Abstract

PURPOSE:To crush a timber always to the same shape by disposing a small roller for transportation between the space part formed between feed rollers and a turn table plate. CONSTITUTION:The inside space part 72 on the crushing device side of the feed roller 71 is provided with the small roller 75 having an axial projecting part 74 on the outer periphery by pivotally supporting the roller by means of a shaft 77 and a bearing 79. The shaft 77 is interlocked to by a chain 84 to a shaft 51 of the feed roller 71. The feed roller side to be pivotally supported on the other revolving shaft is similarly constituted. Timber is pressed and held by a spring between both feed rollers 71 driven by a hydraulic motor when the timber is pushed from a hopper 41 and the timber is fed toward the turn table plate. The timber is cut by a planing blade to small pieces which are further crushed by a crushing blade. The crushed pieces are then held and fed by the small roller 75.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to a wood crusher that feeds and crushes wood toward a rotary base plate having a plane blade on one side.

[0002]

2. Description of the Related Art Conventionally, in a wood crusher of this type, a feeding device for feeding wood toward a rotary base plate has a structure as shown in FIG. 13, for example. That is, a horizontal shaft 9 driven by a hydraulic motor 7 is provided at a position close to the rotary base plate 3 on a hopper 5 provided with a plane blade 1 and facing the rotary base plate 3 rotated by the drive of the engine. Is provided with a feed roller 11 and faces the feed roller 11 to the wood 13
The feed roller 15 that holds the shaft is fixed to a shaft 19 that is driven by a hydraulic motor 17, and the shaft 19 is supported movably in the lateral direction through the long holes 21 and 21 and is moved by the ammunition machine 23 in the direction of the feed roller 15. Being energized. Feed roller 1
The outer peripheral surface of 1, 15 has a large number of axial projections 25, 2
5, ... are formed.

When the wood 13 placed on the popper 5 is pushed toward the rotary base plate 3, the feed roller 15 is spread against the ammunition 23, and the wood 13 is fed by the hydraulic motors 7 and 17. It is sandwiched between the rollers 11 and 15, pushed into the rotary base plate 3, and cut into small pieces by the plane blade 1.

[0004]

In the conventional wood crushing machine, when the wood 13 has been pushed in by the feed rollers 11 and 15, it is formed between the feed rollers 11 and 15 and the rotary base plate 3 having a plane blade. The piece of wood pushed into the space 27 (shown by the diagonal lines in FIG. 13) is released from being held and moves freely, and when it is pushed by the next piece of wood, the posture changes and There has been a problem that the operation is stopped due to a different shape or being drawn into the feed roller and caught in the feed roller.

[0005]

SUMMARY OF THE INVENTION The present invention provides a small roller for conveyance in a space formed between a feed roller and a rotary base plate.

[0006]

According to the present invention, when the wood fed by the feed roller is completely fed, the wood piece further fed by the small roller and fed by the small roller to the rotary base plate is between the small roller and the rotary base plate. Since the space part is small, it becomes almost a strip, and it does not lead to a situation such as operation stop due to biting into the feed roller.

FIG. 12 shows another embodiment of the present invention, in which the floor surface of the hopper 41 is inclined and the rotary shaft 51 of the feed roller 71 and the rotary shaft 53 of the feed roller 97 are horizontal.
The feed roller 97 is vertically movable up and down diagonally above the feed roller 71, and the small roller of the feed roller 97 is eliminated.

In the present invention, the feed roller system is not limited to the embodiment, and the feed roller may be one.
The present invention can be applied to a method in which the number of rollers is one, a method in which both of them are moved by two feed rollers, and the method of the feed rollers may be either a vertical axis or a horizontal axis.

[0019]

According to the present invention, when the feeding roller finishes pushing, the small roller further pushes it in, so that the wood piece does not change its posture between the feeding roller and the rotary base plate and has the same shape. It can be crushed and does not get caught in the feed roller.
