  A coulter 18 is rotatably attached to the coulter attachment arm 17. During agricultural work by the agricultural work machine 1, the coulter 18 shallowly enters the ground surface of the field and leaves residual roots of crops (for example, sugar cane which has already been harvested) left on residues in the ground (for example, straw and weeds). Perform functions such as cutting.

  The feature of the present invention is that the left and right positioning agricultural working tool holders 11 are fixed so that the fixing positions to the left and right ends of the horizontal frame 2 can be easily adjusted. With such a configuration, it is possible to easily adjust the distance between the left and right positioning agricultural implement holders 11, the knife beam 15, and the coulter 18.

(Fixed position adjustment structure)
The structure 22 (hereinafter referred to as "fixed position adjusting structure") for adjusting the fixed position of the left and right positioning agricultural work tool holder 11 will be described with reference to Figs. 3 (a) and 4 schematically showing its configuration and operation. , Will be described below. The appearance of the members shown in FIGS. 3 (a) and 4 which are schematic views is slightly different from the appearance of the members of this embodiment shown in FIGS. 1, 2, 5 etc., but the same reference numerals are used for the same members. .

  As shown to Fig.3 (a), the closing plate 23 in which the screw hole 24 was formed is being fixed to the edge part of the right and left of the horizontal flame | frame 2. As shown in FIG. Further, on the outer surface of the lateral frame 2 at a position closer to the center by a predetermined distance from the left and right ends of the lateral frame 2, the left and right regulating members 27 project integrally or separately from the lateral frame 2. It is fixed at the center and immovable. The "predetermined interval" will be described later. The restricting member 27 may be configured to be immovably fixed by a fixing tool such as a bolt after adjusting the fixing position in the left-right direction of the horizontal frame 2.

  The horizontal frame 2 is fitted to the left and right positioning agricultural implement holders 11, and the fitting hole 28 (Fig. 1) has a shape and a dimension that enables the positioning agricultural implement holder 11 to slide relative to the lateral frame 2. Although the fitting cylinder 12 is provided in 2, 5, etc., it is penetratingly formed in the left-right direction in FIG.

  The positioning agricultural implement holder 11 is attached to the end of the lateral frame 2 by the horizontal frame 2 being fitted in the fitting hole 28, but the pressing member 29 is closed from the outside of the positioning agricultural implement holder 11 It is fixed to the plate 23 by means of bolts 30 and provided immovably at the end of the transverse frame 2. The pressing member 29 inserts the bolt 30 into the bolt insertion hole 31 and screws the bolt 30 into the screw hole 24 of the closing plate 23 of the horizontal frame 2 to fix it.

  A plurality of spacers are fitted and attached to the left and right ends of the horizontal frame 2 respectively. In the present embodiment, as shown in FIG. 1, FIG. 2 (a), FIG. 3 (a), FIG. 4 and FIG. 5, the plurality of spacers, the first spacer 33, the second spacer 34 and the third spacer 35 The structural example which provided three spacers is shown.

  The spacer may be of any configuration that can be attached to and detached from the lateral frame 2, but the spacers 34 to 35 shown in FIG. 3A are substantially U-shaped in cross section each having an opening at one end side. A bolt insertion hole 37 is formed in the portion, and it can be mounted by being fitted to the lateral frame 2 and passing the bolt 38 through the bolt insertion hole 37 and fastening with a nut 39.

  Since the spacers 34 to 35 are each formed in a substantially U-shaped cross section, as shown in FIG. 4 described later, when the spacers 34 to 35 are allocated and arranged and mounted on the horizontal frame 2, It is possible to fit into the lateral frame 2 from the opening of the L-shaped spacer and to extract it from the opening (in other words, it can be inserted and removed).

  In particular, even though the plurality of spacers 34 to 35 are attached to the horizontal frame 2 and the pressing member 29 is fixed to the closing plate 23 by the bolt 30, the pressing member 29 will be described later. It is possible to remove and insert from the opening while shifting the spacer toward the substantially U-shaped opening without removing the.

  Note that two modifications of the spacer are shown in plan views in FIGS. 3 (b) and 3 (c), respectively. Both the spacer 45 shown in FIG. 3 (b) and the spacer 46 shown in FIG. 3 (c) are formed of an elastic material, and when attached to the lateral frame 2, the opening is opened against the elastic force. It is configured to be fitted into the lateral frame 2 and elastically press-fit. If a spacer is made in such a configuration, bolts and nuts can be omitted.

  In FIG. 4, the example of adjustment of the attachment position of the agricultural tool holder 11 for positioning which provided three spacers, the 1st spacer 33, the 2nd spacer 34, and the 3rd spacer 35, is shown. In FIG. 4, the first spacer 33 and the second spacer 34 have the same lateral width (for example, 50 mm), and the third spacer 35 has twice the lateral width (for example, 100 mm).

  The first spacer 33, the second spacer 34, and the third spacer 35 are selectively allocated or selectively attached to predetermined positions of the lateral frame 2, respectively, and these spacers allow positioning for the lateral frame 2 to be positioned. Three adjustment examples which adjust the fixed position of the left-right direction of the farming implement holder 11 are concretely demonstrated in FIG.4 (a)-(c).

  In adjustment example 1 shown in FIG. 4A, the first spacer 33, the second spacer 34 and the third spacer 35 are mounted between the regulating member 27 and the positioning agricultural implement holder 11 in the lateral frame 2. Then, the pressing member 29 abuts against the outer surface of the positioning agricultural tool holder 11, and the bolt 30 is inserted into the bolt insertion hole 31 of the pressing member 29 and screwed into the screw hole 24 of the closing plate 23 (FIG. a) Refer to a), and fix the positioning agricultural implement holder 11.

  By adjusting and fixing both of the left and right positioning agricultural implement holders 11 (see FIG. 1) as in this adjustment example 1, the distance between the left and right positioning agricultural implement holders 11 can be adjusted most widely. It becomes.

  In the adjustment example 2 shown in FIG. 4B, the first spacer 33 and the second spacer 34 are attached between the regulating member 27 and the positioning agricultural tool holder 11 in the lateral frame 2, and the third spacer 35 is It is mounted between the positioning agricultural work tool holder 11 and the pressing member 29. Then, by inserting the bolt 30 into the bolt insertion hole 31 of the pressing member 29 and screwing it into the screw hole 24 of the closing plate 23, the positioning agricultural work tool holder 11 is fixed.

  By adjusting and fixing both the left and right positioning agricultural implement holders 11 as in this adjustment example 2, the distance between the left and right positioning agricultural implement holders 11 can be adjusted to be narrower than in the case of FIG. Become.

  In adjustment example 2 shown in FIG. 4C, the first spacer 33 is mounted between the regulating member 27 and the positioning agricultural implement holder 11 in the lateral frame 2, and the second spacer 34 and the third spacer 35 are It is mounted between the positioning agricultural work tool holder 11 and the pressing member 29. Then, by inserting the bolt 30 into the bolt insertion hole 31 of the pressing member 29 and screwing it into the screw hole 24 of the closing plate 23, the positioning agricultural work tool holder 11 is fixed.

  By fixing both the left and right positioning agricultural implement holders 11 as in this adjustment example 3, the distance between the left and right positioning agricultural implement holders 11 can be adjusted narrower than in the case of FIG. 4B.

  As described above, the first spacer 33, the second spacer 34, and the third spacer 35 are selectively selected between the regulating member 27 and the positioning agricultural implement holder 11, and between the positioning agricultural implement holder 11 and the pressing member 29. By allocating and mounting, it becomes possible to adjust the fixed position of the positioning agricultural tool holder 11 with respect to the lateral frame 2. As a result, the distance between the left and right positioning agricultural implement holders 11 can be appropriately adjusted.

  In general, the left and right positioning agricultural working tool holders 11 are in the same adjustment state, and in many cases, the interval between the two is adjusted as a symmetrical position at the center of the width direction of the agricultural working machine 1. However, the left and right positioning agricultural implement holders 11 may not be in the same adjustment state, but may be in an asymmetrical position according to the state of the field instead of being in a symmetrical position at the center in the lateral width direction of the agricultural working machine 1 .

  By the way, as described above, the regulating member 27 fixed at the center from the left and right ends of the horizontal frame 2 by a predetermined distance is fixed. The “predetermined distance” is the outer surface of the regulating member 27 and the pressure member 29 It is determined in consideration of the configuration in which the first spacer 33, the second spacer 34, the third spacer 35, and the positioning agricultural implement holder 11 are disposed in contact with each other between the inner side surfaces.

  That is, in the “predetermined interval”, the length between the outer surface of the regulating member 27 and the inner surface of the pressing member 29 is the length of the first spacer 33, the second spacer 34, the third spacer 35, and the positioning agricultural implement holder 11. It is determined to be the same as the total length of all the width (hereinafter referred to as “total width of the spacer and the positioning tool holder for positioning”).

  When the length between the outer surface of the regulating member 27 and the inner surface of the pressing member 29 is slightly smaller than the total width of the spacer and the positioning agricultural implement holder, the so-called "tightening" is performed when the pressing member 29 is fixed by the bolt 30. There is a merrit that "there is no looseness between a plurality of spacers, there is no looseness between the spacers and the positioning tool, and a firm fastening without looseness is possible.

  Conversely, when the length between the outer surface of the regulating member 27 and the inner surface of the pressing member 29 is slightly larger than the total lateral width of the spacer and the positioning agricultural implement holder, the pressing member 29 is fixed with the bolt 30 There is a gap.

  The gap here does not mean an excess gap that causes the positioning agricultural implement holder to slide 1 to 2 cm or more to the left and right due to it, and as will be described later, the spacers 33 to 35 are substantially U-shaped. It means a slight gap that can be inserted and removed in the direction of the opening.

  If there is such a gap, as shown in FIGS. 4A to 4C, the allocation of the plurality of spacers 33 to 35 is changed (the arrangement is changed), and the fixed positions of the left and right positioning agricultural implement holders are fixed. When the pressure member 29 is fixed to the closing plate 23, the spacers 33 to 35 can be pulled out and inserted in the direction of the substantially U-shaped opening, and the work for removing or mounting the spacer is easy. The merit of becoming

  Taking into consideration the merits of tightening and fixing as described above and the above-mentioned clearance, the length between the outer surface of the restricting member 27 and the inner surface of the pressing member 29 is the total width of the spacer and the agricultural tool holder for positioning and Even if they do not match exactly, one of the above-mentioned merits can be obtained.

  Therefore, the difference between the outer surface of the restricting member 27 and the inner surface of the pressing member 29 is the same as the total width of the spacer and the positioning agricultural implement holder. Even if there are, it may be "approximately the same length".

  In addition, for example, in the case where it is desired to prevent in advance either the tightening and fixing or the occurrence of the above-mentioned gap from occurring in advance, or when it is desired to actively use any of the respective merits, the tightening and fixing and the above When it is desired to intentionally adopt any of providing a gap, intentionally, the length between the outer surface of the restricting member 27 and the inner surface of the pressing member 29 is set to the spacer and the agricultural tool holder for positioning The configuration may be smaller or larger than the total lateral width of.

(Specific structure of fixed position adjustment structure)
Although the description based on the schematic view of the fixed position adjusting structure 22 which is the feature of the present invention is as described above, the specific structure and function of the fixed position adjusting structure 22 in the present embodiment will be described in FIG. In the present embodiment, as shown in FIG. 5A, the first spacer 33, the second spacer 34, and the third spacer 35 are used for the left and right portions of the horizontal frame 2.

  The first spacer 33, the second spacer 34 and the third spacer 35 are selectively allocated or selected between the regulating member 27 and the positioning agricultural work holder 11 and between the positioning agricultural work holder 11 and the pressing member 29. By mounting in combination, it is possible to adjust the fixed position of the positioning agricultural implement holder 11 with respect to the lateral frame 2.

  For example, as shown in FIG. 5 (b), the first spacer 33, the second spacer 34 and the third spacer 35 can be used as the fitting cylinder 12 of the regulating member 27 and the positioning agricultural tool holder 11 on the left and right of the lateral frame 2. Fit and tighten with bolts 38 for installation. When the three spacers are attached in this manner, the distance between the left and right positioning agricultural implement holders 11 is the widest.

  In the present embodiment, the configuration in which the first spacer 33, the second spacer 34, and the third spacer 35 are used as the plurality of spacers has been described.

  In addition, the plurality of spacers may be a combination of only one having the same width, a combination including ones having different widths, or a combination including ones having the same width and a different width.

  As described above, the agricultural working machine 1 according to the present invention is between the regulating member 27 and the positioning agricultural implement holder 11 and the positioning agricultural implement holder 11 and the pressing at the left and right of the horizontal frame 2 to which the regulating member 27 is fixed. It is possible to adjust and fix the fixing position of the positioning agricultural implement holder 11 by selectively allocating or selectively attaching a plurality of spacers to either or both of the members 29. Become.

  With such a configuration, the agricultural working machine 1 according to the present invention does not have to perform operations such as checking the fixing position in the lateral direction of the agricultural working tool holder 11 for positioning in the horizontal frame 2 in detail at the time of adjustment. It becomes possible to adjust easily and accurately.

  Further, since a plurality of spacers are selectively allocated or selectively combined and mounted on a predetermined portion of the horizontal frame 2, the horizontal fixing position of the positioning agricultural tool holder 11 is determined in advance. It is possible to adjust by selecting the plurality of positions. As a result, the fixed positions of the left and right agricultural tools such as the left and right knife beams 15 and the coulter 18 can be simply, accurately, and adjusted to desired positions.

  Further, in the agricultural work machine 1 of the present invention, since the positioning agricultural work tool holder is not configured to be fastened to the horizontal frame 2 by bolts, apart from the above-mentioned advantageous clearance, the agricultural work tool holder for positioning by normal bolt looseness There is no lateral displacement of 11.

  Furthermore, in the agricultural work machine 1 of the present invention, since the fixed position of the positioning agricultural work holder 11 is adjusted via the spacer, an external force acts on the left and right agricultural work or positioning agricultural work holder 11 during agricultural work. The positioning agricultural implement holder 11 does not shift in the lateral direction.

  Therefore, the fixed positions of the left and right agricultural working tools such as the knife beam 15 and the coulter 18 in the present embodiment do not shift in the lateral direction, and the distance between the left and right agricultural working tools does not change. It will be maintained at intervals, enabling stable farming operations in the field.

  As mentioned above, although the form for implementing the agricultural-working machine which concerns on this invention was demonstrated based on the Example, this invention is not limited to such an Example, The technical said was described in the claim. It goes without saying that there are various embodiments within the scope of the matter.

  For example, the pressing member 29 prevents the positioning agricultural work tool holder 11 and the plurality of spacers (the first spacer 33, the second spacer 34, and the third spacer 35) from coming out of both ends of the lateral frame 2 outward. It is a member of

  Therefore, the pressing member 29 is fixed to the both ends of the lateral frame 2 by welding instead of being configured to be attachable to and detachable from the closing plate 23 by the bolt 30, or integrated as one part of the lateral frame 2 at both ends. It may be configured such that the positioning agricultural work tool holder 11 and the spacer do not come out laterally from both ends of the lateral frame 2.

  In such a configuration, the positioning agricultural working tool holder 11 is divided and the fitting hole is also divided, and the horizontal frame 2 is inserted into the divided fitting holes without being inserted from the end of the horizontal frame 2 Thus, the divided positioning agricultural work tool holder 11 is assembled to the lateral frame 2 so as to be integrated.

  Since the agricultural work machine according to the present invention is configured as described above, in addition to the agricultural work machine provided with knife beams, coulter disks, and a fertilizer discharge port on the left and right, agricultural work tools are provided on the other left and right to adjust the distance between the left and right.
