Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a disc plow-type tilling device that is used by being attached to a tractor.

<Prior Art> A disc plow type tilling device is used by being attached to the rear of a tractor. A tillage device with this value has a disc plow with a plurality of discs installed on a disc shaft, arranged on the left and right so that it forms a letter shape when viewed from above, and
Each Dinuk plow is forcibly driven by power from a tractor. In addition, a rotary plowing part for opening the mouth is provided at a slightly forward position between the left and right disc plows, and the pawl shaft of this rotary plowing part is driven in the up-cut direction to open the plow. I'm trying to open it up.

<Problems to be Solved by the Invention> However, in the conventional tillage device, the claw shaft of the rotary tiller was installed perpendicular to the direction of travel, so even though outward-facing claws were used, the tilled soil mass Another drawback is that waste straw and other debris on the surface of the field are scattered forward toward the tractor. In addition, although I used my claws to send straw flying forward, it was still in its path and I was unable to remove it in any direction.
There was also the problem that if the nail got tangled with the nail, it would end up wrapping around the nail shaft. In addition, in the past, only the rotary tiller was used to till the central part, and a disc plow was used to collect gravel from the left and right on the plowing site, so there was no need to worry about the central part of the ridge being too high. In addition, since the gravel plowed by the disc plow would sit on top of the soil that had expanded and softened due to rotary tilling, there was a risk that the inversion properties of the gravel would be poor in the center.

<Means for solving the problems> In view of such conventional problems, the present invention provides a method for solving the problems of tilled soil,
Actively scatters waste straw, etc. to the front and outside to prevent waste straw, etc. from scattering towards the tractor side and from wrapping around the rotary tiller, and improves the reversibility of the gravel and the ridge shaping effect. It was provided for the purpose of A plowing device in which a rotary plowing part for opening the plow having an outward claw and rotating in an up-cut direction is provided between the disc plows, and the disc plow is forcibly driven by power from a tractor,
The rotary tiller is provided in pairs on the left and right so that the claw shafts thereof are substantially parallel to the disc axis of the disc plow and have a V-shape in plan view.

<Effects of the Invention> According to the present invention, the rotary plowing part for plowing which has an outwardly directed claw and rotates in the up-cutting direction is arranged so that the claw axis thereof is substantially parallel to the disc axis of the disc plow and is in the shape of a rectangle in plan view. Since a pair of blades are provided on the left and right so that the blades form a shape, the rotation of the outward claws can actively blow away tilled soil clods, waste waffles, etc. on the surface of the field in an anterolateral direction in the direction of travel. Therefore, unlike the conventional method, the waste straw is not blown forward toward the tractor, and the waste straw and the like are removed outward, so that it is completely possible to prevent the waste straw from becoming entangled. Moreover, since the rotary tiller blows the tilled soil in an anterolateral direction, the opening of the tillage mark is effective, and the disc plow can turn over the gravel well, and it also brings the gravel from the left and right to the center. However, the medium heat part does not rise particularly high, and the ridge shaping effect is good.

<Example> Hereinafter, the present invention will be described in detail with regard to the illustrated example.
In the figure and FIG. 2, (1) is a tractor, (2) is a rear wheel, and (3) is a PTO shaft. (4) is a hydraulic system, which has a pair of left and right lift arms [51'k[f]. (6)
C. A tilling device with a three-point link a! at the rear of the tractor (1) consisting of a top link (7) and a pair of left and right lower links (8). It is mounted to be pulled up and down via a structure (9).

The tilling equipment @ (6) consists of a machine frame αQ, a pair of left and right disc plows Qll, and a pair of left and right rotary tillers for mouth opening (12).
Support tubes (141
and an overhanging tube GFj provided from each outer end of this support tube (141) so as to have a shape in a plan view,
A transmission case O extending downward from the outer end of each overhanging cylinder US
G, and each projecting tube tap is reinforced with a link αη. Each disc plow Qll has a disc shaft α9 that is rotatably supported between a transmission case αG and a gear case Q81 on the inner end side, and a solid phase (the cause of the seven strange cloth visits) attached to this at equal intervals. /7 eln J-9m-h--b Female disc plow α]) are arranged in a V-shape in plan view. The input gear case 7-a3 has an input shaft and a bevel gear so that the FTO shaft (3) of the tractor (1) is inputted through the universal joint shaft (2 nt-) as shown in Fig. 3. This bevel gear mechanism (C) connects each Dinuk plow through the support part side, the transmission shaft in the overhanging cylinder, the universal joint (■), the transmission shaft (■), and the winding transmission mechanism in the transmission cane αG. The rotary tiller o2 is configured to transmit power to the disc shaft 09 of the rotary tiller o2.
It consists of four outward-facing tilling claws planted on it,
The claws are arranged substantially parallel to each disk axis α9 and in the shape of a letter when viewed from above. Each pawl shaft ■ is rotatably supported between the bearing case in the center front part and the gear booth rib, and the disc shaft α9 is supported via the gear C1υ in the gear case [phase] as shown in FIG. This pawl shaft (to) is rotated in the up-cut direction (arrow a) opposite to the disc shaft (1G).The tilling pawl of each rotary tiller is connected to the pawl shaft (in the embodiment). The gear cases a3 are arranged in a line on top of the gear case, but the phase is 180 degrees different on the left and right sides.Each gear case a3 is supported by the machine frame αQ via a bracket (c), and the bearing cane c
It is supported by the input gear case a3 via the ni bracket (to). The gear case (toward) is provided with the front and lower sides inclined in a square shape.The claw shaft ■ is located below the disk shaft 09, and the radius of the rotary tilling part U is smaller than that of the disk ■. It is. (2) is a rotary cover provided above the hill portion Gz of the rotary #, which is attached to a bracket (to) or the like. In addition, this rotary cover (to)
Although it is desirable that most of the tilled soil is scattered to the front and sides, it can also be omitted.

In the above-mentioned groove shape, when plowing the field, the power from the PTO@i31 of the tractor (1) forces all the disks ω of the disk plow συ to drive the disk axis a9 in the direction of the arrow b. While forcibly driving the rotary tiller az2 in the direction of the arrow a, turn the tiller (6
) Full towing. That is, the PTO shaft (3) of the tractor (1)
The power is transmitted from the universal joint shaft 12D to the tilling device (6) through the input shaft, and from the bevel gear i in the gear case 03 to the transmission shaft example ■, through the wrap transmission mechanism ω, to the disc shaft o9. As a result, the disks (2) of the left and right disk books (11) rotate about the disk shaft (19 turns Q in the direction indicated by the arrow b).

- When the disc shaft α9 rotates, power is transmitted to the pawl shaft through the gear C(1) c+a in the gear case (to), and the tilling pawls ■ of the left and right rotary tilling part mouths are in opposite phases to each other. Rotate in the direction of arrow a to avoid interference.

When the rotary tilling part concave turns in the direction of arrow a (then, since the claw shaft (support) is inclined with respect to the direction of movement and the tilling claw is of the outward type, the tilled soil lumps and waste straw etc. As shown in Fig. 5, it can be removed by blowing it forward and outward in the direction of travel (arrow C) and to the side as shown by arrow d.Therefore, tilled soil clods, waste straw, etc. can be removed toward the tractor (1) side. It will not fly away.Also, since the tiller is removed from the center to the outside as indicated by the i-d arrow, and brought to the front of the passage position of the disc book ■, the passage traces of the left and right rotary tiller concave , it becomes a groove shape with a predetermined tilling depth and has a good mouth opening effect.Rotary tilling section Q31
After opening by C, as shown in Fig. 6, the field is plowed by rotating the disc ■ of the disc book u11, and the gravel 3 is plowed.
Flip it 1m and move it towards the center to form a chain.

In this case, since the opening is good as described above, the innermost disk (2) plows the sides of the groove-like portion, and the reversibility of the gravel is very good. Also, each disc
Since the tilled soil is tilled and turned over by the rotary tiller u2, tillage ±371 is collected in the center, and since the tillage remains are backfilled, the ridges formed after tilling are also particularly high in the center. There is no problem, and the ridge adjustment effect is good.

If the claw shaft of the rotary tiller ■ is made lower than the disc shaft Og, the length of the tiller claw (support) can be reduced, and the input gear case located above can be lowered, making it easier to till the rotary tiller. The height of the entire device (6) can be reduced.

The tilling arrangement of the rotary tiller (2) may be arranged in a line in the axial direction on the claw shaft (2), but as shown in Fig. They may be provided at roughly even corners in the direction, and this arrangement is effective in preventing vibrations during tilling.
