Capacity can be increased. Moreover, the swing member 53
Is provided forward and below the rotating shaft 51 of the feed roller 49, so that even if a force acts on the feed roller 49 in the forward direction due to the branches and leaves on the fixed plate 57, the force Also, the swinging member 53 swings to raise the feed roller 49.

Also, a feed hydraulic pump 45 for rotating the feed roller 49 and a cutting hydraulic pump 22 for rotating the rotary rotor 19 are separately provided, and a hydraulic circuit for the feed means 43 is provided. Since the hydraulic circuit for the cutting machine 17 is provided separately, even when the cutting machine 17 is stopped, the feeding means 43 can be driven arbitrarily, thereby allowing the rotation between the rotary blade 33 and the fixed blade 59. There is an advantage that the feeding roller 49 can be rotated in the reverse direction even if the branch tree is bitten.

Further, the discharge amounts of the feed hydraulic pump 45 and the cutting hydraulic pump 22 are set such that the outer edge of the feed blade 50 rotates 20 mm per rotation of the rotary rotor 19, that is, the feed roller 49 rotates. Since it is controlled so that a desired amount of branch trees per one rotation of the blade 33 is fed to the rotating rotor 19 side, the amount of branch trees sent per one rotation of the rotary blade 33 can be adjusted, and the rotation can be performed. By cutting the blade 33, the cutting can be made to have a certain size. Moreover, by changing the discharge amount of the feed hydraulic pump 45 or the cutting hydraulic pump 22, it is possible to change and set the amount of branch and tree sent per one cutting of the rotary blade 33. The setting of the size of the cutting obtained by cutting the blade 33 and the fixed blade 59 can be changed.

The cutting operation can be performed smoothly without hindering the rotation.

Further, a substantially L-shaped mounting notch 29 is
The rising surface against the mounting surface 30a that abuts the side surface of 33
Since the peripheral side of 30b is formed so as to be inclined toward the blade end 34, centrifugal force acts on the rotary blade 33 and the holding member 31 attached to the mounting notch 29 when the rotary rotor 19 is rotated at high speed. However, a reaction force from the rising surface 30b acts on the holding member 31 against this centrifugal force, and the holding member 31
The rotary blade 33 can be accurately held by the 31 and the force acting on the bolt 37 as a fixing means can be reduced.

The hole 35 for mounting the rotary blade 33 is a blade end.
It is formed as a long hole extending to the 34 side, and the rotary blade 33 is
Is provided so as to be slidable on the blade end portion 34 side, so that if the rotary blade 33 does not protrude from the peripheral edge of the rotary rotor 19 by a desired length due to wear of the blade end portion 34, the bolt 37
To release the pinching by the holding member 31,
To the blade end 34 side along the hole 35,
The protruding length of the blade end 34 of the 33 can be adjusted. In particular, since the hole 35 is formed with a width substantially equal to the outer diameter of the leg of the bolt 37, the rotary blade 33 does not shift in the lateral direction (the axial direction of the rotary rotor 19) during this sliding.

Moreover, since the rotary blade 33 is sandwiched and mounted by the pressing member 31, even when the rotary blade 33 is slid along the hole 35 toward the blade end 34, the pressing member 31 is not required. This has the advantage of receiving the reaction force of the centrifugal force from the rising surface 30b.

Further, the rotary rotor 19 can be easily manufactured by engraving the mounting notch 29 and the escape portion 28 adjacent to each other, and the rotary blade 33 and the holding member are bolted to the mounting notch 29 by the bolt 37. There is an advantage that the rotary blade 33 can be easily mounted on the rotary rotor 19 by mounting the rotary blade 19.

The screen 39 is detachably attached to the discharge port 38 of the cutting machine 17.

If the size is smaller than the diameter of the tailgate 12
And the size of the cut material stored in the storage box 1 can be reduced to a certain size or less.
When the screen 39 is removed, the rotating blade 33 and the fixed blade 59
Thus, the cut material can be discharged to the tailgate 12 as it is.

Further, the cuttings cut by the cutting machine 17 are discharged into the tailgate 12 which closes the storage box 1, and the cuttings 17 are put into the storage box 1 by the pushing device 101 mounted on the tailgate 12. Because of the feeding configuration, the cut material does not scatter outside the storage box 1 when stored in the storage box 1.
