It is arranged so as to be located below the outlet filter at the bottom of the crushing chamber. When crushing objects to be crushed such as trees and tree branches, the objects to be crushed are put into a hopper and supplied to a crushing device by a supply conveyor. The object to be crushed fed by the supply roller onto the fixed blade is crushed into chips in the crushing chamber between the moving blade and the fixed blade which are rotated by the rotary drum, and the crushed product is the outlet filter at the bottom of the crushing chamber. Through the passage hole and falls on the discharge conveyor, and is discharged to the outside by the discharge conveyor.

破損等の不具合が発生する。By the way, when the crushed object is waste wood generated by dismantling a house, etc., the crushed object that is thrown into the loading section by a loading machine such as a power shovel with a grapple is a foreign substance such as a metal lump that is not to be crushed. May be mixed in. When foreign matter such as a metal lump is mixed, a moving blade such as a cutter bit mounted on the rotary drum of the crushing device is overloaded and a problem such as damage to the crushing device occurs.

成したものがあった。For this reason, the fixed blade support for fixedly supporting the fixed blade has a structure that can be opened and closed by pivotally supporting it at an appropriate position that is not coaxial with the head side rotation shaft of the supply conveyor, and further supports the fixed blade support with shear pins. Then, when the reaction force that the fixed blade receives during crushing becomes excessive, the shear pin is broken to avoid overload, and the crushing device is protected from damage.

掛からないように、この隙間は微小に設定されている。The object to be crushed, which is put into the hopper and supplied by the supply conveyor, is fed onto the fixed blade by the feed force of the feed roller rotating above the rotary shaft on the head side of the feed conveyor. Therefore, this gap is set to be small so that the material to be crushed does not get caught in the gap between the rotary shaft of the head and the fixed blade of the supply conveyor.

いう不具合があった。Therefore, when the fixed blade support is pivotally supported at an appropriate position which is not coaxial with the head side rotation axis of the supply conveyor, the shear pin is broken due to the inclusion of metal lumps, etc. When the support rotates, the fixed blade moves only in the direction away from the rotary shaft on the head side of the supply conveyor, and this gap expands. There was a problem that the fixed blade support could not be returned to the original position and the crushing work could be restarted unless it was caught.

枝粉砕機を提供することを目的とする。Further, when the shear pin is broken, a new shear pin is required for repairing the shear pin, it takes time to replace the shear pin, and the grinding operation must be interrupted during that time, which is uneconomical. The present invention is to solve the above problems in a tree crusher, hold a fixed blade against the crushing reaction force received at the time of crushing, and attach a metal lump etc. to the object to be crushed and attach it to the rotating drum. If the moving blade is overloaded, the fixed blade can be rotated in a direction away from the reaction force to prevent damage to the crusher. An object of the present invention is to provide a tree crusher capable of easily returning to a state in which crushing work can be performed without a crushed product, a metal lump, or the like being caught.

Based on the hydraulic cylinder that holds the fixed blade support in place, the hydraulic pressure sensor that detects the internal pressure of the hydraulic cylinder, and the detection data from the hydraulic sensor, the fixed blade support can be used when the grinding reaction force received by the fixed blade becomes excessive. By providing a controller for controlling the hydraulic cylinder so as to rotate in a direction away from the crushing reaction force, the fixed blade support that has rotated can be easily returned to its original position by the operation of the hydraulic cylinder.

The gap between the drive shaft 15 on the head side of the supply conveyor 2 and the fixed blade 10 is kept small. Therefore, the object to be crushed, the metal lump, etc., which are being crushed, are not caught in this gap, and the metal lump or the like moves with the rotation of the fixed blade support 9 and the fixed blade 10.
It slides down the slope formed by the and is discharged to the outside of the crushing device 2 through an opening opened at the bottom of the crushing chamber 6.

It is not necessary to remove the object to be crushed or the metal lump sandwiched in the gap or replace the parts such as the shear pin, and the fixed blade support 9 that has been rotated can be easily returned to the original position to restart the crushing work promptly. Therefore, the work efficiency is good and it is economical.

できる。As described above, in the tree crusher of the present invention, when a lump of metal is mixed into the object to be crushed at the time of crushing and the moving blade mounted on the rotary drum is overloaded, It is possible to prevent damage to the crushing device by rotating the fixed blade in a direction away from the reaction force. Even if the fixed blade rotates, the object to be crushed, the metal lump, and the like being crushed are not caught in the gap between the supply conveyor and the fixed blade, and the crushing operation can be easily restored.
