A flat device 85 is attached. The leveling device 85 is disposed on the rear side of the digging rotor 32. The leveling device 85 has an inclined portion 86 that extends in the vertical direction and inclines backward as it goes outward in the body width direction, and the inclined portion 86 is disposed at a symmetrical position with respect to the center in the body width direction. . For this reason, when the residual trunk processing machine 1 advances to the front side, the soil on the upper surface of the ridge U where the residual trunk Z is dug up is leveled by the inclined portion 86, and the surplus soil is machined along the inclined portion 86. It moves outward from the center in the width direction and is discharged to the outside of the ridge U.

  Next, the operation | movement which performs the residual stem processing operation | work of the residual stem Z planted in the fence U by the residual stem processing machine 1 concerning this invention is demonstrated. As shown in FIG. 3, first, the remaining trunk processor 1 is attached to the rear portion of the traveling machine body 90, and the traveling machine body 90 is installed at a position where the traveling machine body 90 can straddle the ridge U. Then, the traveling machine body 90 is moved forward along the heel U, and the power from the traveling machine body 90 is transmitted to the input unit 27 of the remaining trunk processor 1. When power is transmitted to the remaining trunk processor 1, the excavation rotor 32 rotates in the upcut direction (arrow A direction) and the feed roller 45 rotates in the arrow B direction as shown in FIG. To do. When the traveling machine body 90 moves forward in such a state, the stem Zk of the remaining trunk Z is pushed down toward the front side by the forward movement of the traveling machine body 90. Here, when the stem Zk of the remaining trunk Z pushed down toward the front side is inclined in the left-right direction, the inclination of the stem Zk is corrected by the guide member 81 and guided toward the center in the body width direction. For this reason, the remaining trunk Z is pulled into the aircraft with a small inclination in the left-right direction, and the remaining trunk Z can be reliably pulled into the aircraft.

  The remaining trunk Z whose inclination has been corrected by the guide member 81 is digged up by scooping up the root Zn from the lower side to the upper side by the digging rotor 32, and the rotation direction of the digging claw 34 so that the root Zn precedes it. It is drawn downstream. Then, when the root Zn is drawn and moved to the upper side of the digging rotor 32, it is further drawn to the machine body side by the feed roller 45. The feed roller 45 is disposed facing the digging rotor 32 and is rotated in the same direction as the digging rotor 32 on the side facing the digging rotor 32, so that the root Zn is coupled with the digging rotor 32. Send it to the rear side so as to hold it. Further, the feed roller 45 suppresses the vertical movement of the remaining trunk Z caused by the remaining trunk Z digged up by the digging rotor 32 still contacting the digging rotor 32, and sends the remaining trunk Z to the rear side to send the remaining trunk Z. For the processing, the workability of the remaining trunk processing work can be improved.

  Then, the remaining trunk Z is inserted between the pair of first rollers 51 so that the root portion Zn precedes, and conveyed to the rear side while being sandwiched between the pair of first rollers 51. The remaining trunk Z transported by the first roller 51 is transported to the rear side while being sandwiched between the pair of second rollers 52 and sent to the cutting rotor 56 side. The remaining trunk Z sent from the second roller 52 is shredded by a rotating cutting rotor 56, and fragments of the remaining trunk Z are discharged by the blower 59 shown in FIG. The inside is raised and discharged from the upper end portion of the shooter 60 and accommodated in the accommodating portion 70.

  Further, along with such a remaining stem processing operation, as shown in FIG. 5A, the surface of the ridge U from which the remaining trunk Z is dug up by the inclined portion 86 of the leveling device 85 is leveled. That is, when the remaining trunk processing machine 1 advances to the front side, the surface of the ridge U that has been dug up and roughened by the remaining trunk Z is leveled by the front side movement of the inclined portion 86. Then, the soil remaining without being leveled by the inclined portion 86 is washed away obliquely rearward and rearward along the inclined portion 86 and discharged to the outside of the ridge U. For this reason, the surface of the kite U can be smoothed smoothly, and as a result, the work of leveling the kite U in the post-work of the kite U is omitted, and the labor of the post-work can be reduced. . Further, even when a part of the shredded fragment of the remaining trunk Z falls on the ridge U, the fragment is sunk into the soil where the fragment is made uniform by the inclined portion 86. For this reason, the operation | work for putting a fragment | piece in a cage | basket in the post-operation of the cage | basket U becomes unnecessary, and the labor of a post-operation can be reduced more.

  In this way, the remaining trunk Z planted in the basket U is continuously processed along with the forward movement of the traveling machine body 90.

  As shown in FIG. 1, the rear wheel 14 is provided so that the position of the rear wheel 14 can be adjusted in the vertical direction with respect to the body frame 10, so that the position of the rear wheel 14 is moved up and down with respect to the body frame 10. When the remaining trunk processing machine 1 is mounted on the traveling machine body 90, the tilling depth of the excavation rotor 32 can be adjusted. For this reason, the tilling depth of the excavation rotor 32 can be adjusted according to the overhanging depth of the root Zn of the remaining trunk Z planted in the fence U, and the root Zn of the remaining trunk Z is reliably dug up from the fence U. Processing can be performed.

  Further, as described above, since the cutting device 40 is configured independently from the body frame 10, the cutting device 40 and the body frame 10 can be assembled separately, and the assembly work of the remaining trunk processing machine 1 can be easily performed. can do. Furthermore, by removing the cutting device 40 from the machine body frame 10, it can be used as a cutting device alone. Further, when maintenance is performed on the cutting device 40, if the cutting device 40 is detached from the body frame 10, maintenance work on the cutting device 40 can be easily performed.

  Furthermore, in the above-described embodiment, the remaining trunk processor 1 is of a type that is pulled by the traveling machine body 90, but the remaining trunk processor 1 may be configured to be capable of traveling. In this case, a member that can push down the remaining trunk Z forward is provided in front of the guide member 81.
