Description

  The present invention relates to a cutting device that cuts and harvests the foliage of a cultivated plant extending from a ridge, and a foliage guide device attached to the cutting device.

  In perennial tuberous root plants such as asparagus and udo, young shoots grow from the root. This young shoot is harvested and sold as an edible material, and is used as a food material such as salad. When cultivating tuberous root plants, the roots are grown after harvesting the young shoots so that the young shoots are sufficiently grown at the harvest time (for example, spring). When the root grows, the foliage grows on the ground. The foliage extends radially upward from the bud where the tuberous plant is planted, or protrudes to the side of the bud and falls into the ground below the bud. However, the foliage part is indispensable for photosynthesis for growing the root part, while it becomes a hindrance when young shoots are harvested at the next harvest time. Therefore, the grown foliage is cut before the harvest time (for example, from autumn to winter). For this cutting operation, a cutting device (for example, the agricultural machine 10 described in Patent Literature 1) that cuts and cuts the stems and leaves of the cultivated plant extending from the straw is used.

  The agricultural working machine 10 described in Patent Literature 1 includes a working machine main body 11 and a foliage derivative 71 (divider), is attached to the rear portion of the tractor 1, and is used by running the tractor 1 backward (retreating). The foliage derivative 71 is detachable so as to be separated from the tractor 1 on either the left or right side or both sides of the rear part of the work machine body 11 (front part of the tractor 1 in the direction of travel) and protrude in the direction of travel (backward of the tractor 1). It is attached. The foliage derivative 71 is disposed in an inclined shape so that the rear end is positioned downward, and the lower end portion, which is the rear end portion, is formed in a tapered shape. The height of the foliage derivative 71 can be adjusted with respect to the work machine main body 11, and the tilt angle with respect to the horizontal can be adjusted by rotating the operation body 50 for height adjustment. In Patent Document 1, the foliage derivative 71 is positioned in the forward region E in the traveling direction of the cutting rotation part 30 of the work machine body 11 by guiding the foliage part A1 on the ridge H1 of the field H, and cutting the cutting rotation part 30 It is described that the blade 23 cuts the foliage A1 finely.

  In the agricultural working machine 10 described in Patent Literature 1, one end of the rod-like foliage derivative 71 is positioned in the vicinity of the skirt of the ridge H1 of the field H. The foliage derivative 71 extends in the length direction of the heel H1 and is inclined so as to rise toward the front portion of the work implement body 11 (the rear side in the work direction, the forward direction of the tractor 1). For this reason, the foliage derivative 71 induces the foliage part A1 on the upper surface of the foliage derivative 71 so as to scoop up the foliage part A1.

  However, the foliage A1 extends from the ridge H1. For this reason, the tip of the foliage derivative 71 hardly comes into contact with the foliage part A1, and finally comes into contact with the foliage part A1 at a portion near the rear part (front part in the traveling direction of the tractor 1) of the foliage derivative 71. That is, the portion on the front side (the rear side of the tractor 1) from the portion that contacts the foliage portion A1 for the first time in the foliage derivative 71 does not effectively induce the foliage portion A1 extending from the ridge H1.

  When the tractor 501 travels on the tractor 501 along the rod 302 in this state, the tip portion 152 of the foliage guidance device 151 scoops up the foliage portion 303 extending so as to craw near the ground 301. At this time, the guide rod 160 hangs from the rod 302 and contacts the foliage 303 that is separated from the ground 301. Here, since the foliage portion 303 is fixed to the heel 302, the foliage portion 303 slides and moves inward while being pulled by the guide ridge 160 as the guiding heel 160 moves forward in the traveling direction, and the side plate 111 is moved. In the vehicle width direction inner side, it is guided above the shoot upper part 151a. When the tractor 501 further travels, the foliage portion 303 moves further in the vehicle width direction due to the inclination of the foliage upper part 151a.

  When the tractor 501 travels, a part of the driving force of the tractor 501 is input from the input shaft 116 and transmitted to the rotor shaft 112 via the power transmission unit 115, and the rotor shaft 112 is rotated around the axis. Thereby, the cutting blade 103 rotates and the foliage part 303 induced | guided | derived by the foliage guidance device 151 is cut. The foliage portion 303 is cut from the ground 301, is caught in the rotation locus 103a, and moves along the guide path 169 shown in FIG. The foliage portion 303 is pulverized while moving along the guide path 169 and falls to the ground 301 from between the cutting blade 103 and the rotor cover 110 on the rear side in the traveling direction with respect to the rotor shaft 112.

  Thus, according to the cutting device 101, the guide rod 160 contacts both the foliage portion 303 that crawls the ground 301 and the foliage portion 303 that hangs down from the reed 302, and the foliage portion 303 that extends from the reed 302 is efficiently cut. It is. In the reaping device 101, the foliage guiding device 151 has the guiding member 158 and spreads in a plane, and since this guiding member 158 is inclined inward in the vehicle width direction, more foliage portions 303 are harvested. It is reliably guided to the blade 103. Further, the lock mechanism 168 makes it easy to attach and detach the foliage guidance device 151 to the reaping device main body 101a.

  FIG. 10 is a left side view of the reaping device main body 101 a held by the stand 201. In the present embodiment, the stand 201 can hold the reaping device main body 101a. Here, the stand 201 is used in a state of being placed on the placement surface 401, and extends upward from the base 202 along the placement surface 401, a caster 203 attached to the base 202, and the base 202. And a stand arm 204 inclined with respect to the vertical direction. An example of the placement surface 401 is the ground surface 301. Another example of the mounting surface 401 is a floor surface (not shown) of a warehouse.

  The cross-sectional shape of the mounting arm 161 provided in the foliage guidance device 151 is the same as the cross-sectional shape of the stand arm 204. The stand arm 204 has a pin mounting hole 205. For this reason, the first pin 166 is inserted into one pin mounting hole 205, the first pin 166 is hooked on the pin receiving portion 164, and the stand arm 204 is fitted into the holder 163 of the foliage guiding device 151. The pin mounting hole 205 and the through hole 165 of the holder 163 are aligned and the second pin 167 is inserted, whereby the reaping device main body 101a is held in a state separated from the mounting surface 401 by the stand 201. . Thus, in the reaping device 101 of the present embodiment, the holder 163 is used to attach the foliage guidance device 151 to the reaping device main body 101a and also to hold the stand 201 on the stand 201.
