When the upright remaining stem on the ground coming in from approaching the rotating shaft 1, the upright remaining stem is pushed downstream by the rotating blades 2 provided on the rotating shaft 1 in a plurality of stages. At this time, since the movement of the remaining stem is stopped by the fixed blade 6, the upright remaining stem is cut short by being pinched by the rotary blade 2 and the fixed blade 6, and falls downward. The roots of the upright remnants below the remnant treatment device remain in the soil. The stem portion of the upright remaining stem is overlapped in a plan view during rotation, and the blade is rotated by sandwiching the stem between the blade portion of the rotary blade 2 and the blade portion of the fixed blade 6 provided in a pair near the height direction. The stems of the upright stems caught in the soil are easily cut into a plurality of stems without moving vertically.

According to the first aspect of the present invention, since the root portion of the upright remaining stem lower than the stem processing device is left in the soil as it is and the rotary stem 2 and the fixed blade 6 cut the stem portion located in the device, cutting is performed. Sometimes, the stem can be easily cut without vertical movement. Further, since the upright stem that has entered from the front is cut and immediately exits the device through the side opening 5 on the lower rotation side, the amount of rotation of the remaining stem in the device is reduced, and the horsepower loss is small and the cutting efficiency is reduced. improves. According to the second aspect of the present invention, the stem portion of the upright remaining stem is overlapped in a plan view during rotation, and the blade is rotated by sandwiching the stem between the pair of rotating blades 2 and fixed blades 6 provided near the height direction. Therefore, the stem of the upright remaining trunk whose lower end portion is grasped in the soil can be easily cut into a plurality of stems without escaping in the vertical direction. According to the third aspect of the present invention, the side cover 7 that covers the outside of the side opening portion 5 gradually increases the outer wall surface from the upper end to the lower end, and a discharge port 8 is provided at the lower end. Therefore, when the side cover 7 is not provided, there is a possibility that the remaining cutting stem may scatter directly to the side and be damaged by contact with another object. In the present invention, however, the remaining stem jumps out of the apparatus from the side opening 5. The remaining cutting trunk can be easily guided to the lower side of the side cover 7 and can be guided to fall from the discharge port 8 at the lower end toward the surface of the soil. According to a fourth aspect of the present invention, an elastic body 9 is provided on the inner wall surface of the side cover 7 so as to cover a part or the whole of the inner wall surface. 7 can be guided to fall on the soil surface while reducing the contact sound and repulsive force in the inside 7, and it is quiet, and the scattering movement of the cutting residue on the soil surface can be reduced, which is safe. According to the fifth aspect of the present invention, the remaining cutting stem carried around without being discharged from the lower end of the side cover 7 is attached to the upper cover 11 provided on the opposite side of the side cover 7.
The rotary blade 2 can be discharged from here and can not be left in the apparatus, so that there is no contact of the rotary blade 2 again and the horsepower loss is reduced. According to a sixth aspect of the present invention, the remaining trunk processing device is mounted on the front of the body 12 of the moving vehicle, and the cutting operation is performed by running the body 12 forward, and the driver can ride or follow the rear of the body 12 when the vehicle is running. In this case, the front part of the shadow of the trunk processing unit cannot be directly seen. However, since the rear window 13 is provided on the back part of the cover 3 of the trunk processing unit, the rear window 13 allows the front opening 4 of the cover 3 to be opened. , The driver can directly confirm the approach position of the upright standing trunk standing forward, move the steering of the body 12 left and right to move forward, and the driving operation is easy. The invention according to claim 7 is directed to a rotary blade 2 of the remaining stem treatment device.
