Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for feeding wood into a wood crusher.

Conventionally, in crushers that produce sawdust by pulverizing thinned wood, the thinned wood is fed in while being held between a conveyor and a presser roller. There were drawbacks such as the inability to send.

In order to eliminate the above-mentioned drawbacks, the present invention is a device in which plate conveyors are vertically mounted on shafts in a machine frame, and the plate conveyor feeds the wood while holding it between the plates. It is also characterized by the fact that even scraps can be fed in regardless of the size of the material. Hereinafter, the configuration of the present invention will be explained with reference to embodiment figures.

A lower longitudinal rotation shaft 2, 2' is mounted on the front and back positions of the side plates 1, 1' facing each other on both sides, and a pair of chain wheels 3, 3 fixed to the lower longitudinal rotation shaft 2, 2' and a chain wheel 3. The lower plate conveyor 5a with plates 4 successively attached to the side plates 1, 3' is adjusted, and the upper front rotating shaft 7 is set by protruding projecting plates 6, 6' on the front upper surface of the side plates 1, 1'. At the same time, both ends of the rotating shaft 7 are made to protrude outward from the projecting plate, and one bearing 8 and two bearings 9 are freely suspended on the protruding parts of both ends of the rotating shaft 7. An arm rod 10 and an arm rod 10' which also serves as a chain cover are provided protruding outward from the rear upper ends of the side plates 1, 1', and the arm rods 10,
A bearing 8' and a bearing 9' are provided at the tip of the shaft 10' to support the upper rear rotating shaft 7', and the sprocket wheel 1 is mounted on the rotating shafts 7, 7' front and rear facing the arm rod 10' which also serves as a chain cover.
1 and 11', the endless chain 12 is adjusted, and the rear end of the cover frame 13, which has an inverted U shape when viewed from the end, is connected to the upper rear rotating shaft 7'.
At the same time, the lower surfaces of both sides of the cover frame 13 are attached to the upper surfaces of the side plates 1 and 1', and the interlocking shaft 1 is attached to the front end of the cover frame 13.
4 is mounted on a shaft, and within the cover frame 13, a pair of chain wheels 15, 15 are mounted on the rotating shaft 7', and a pair of chain wheels 15' are mounted on the interlocking shaft 14.
15' is fixed to constitute a lumber feeding device 16 in which an upper plate conveyor 5b to which boards 4 are successively attached is adjusted.

In addition, numeral 17 in the figure indicates a crusher cutter section. Next, the effects of the present invention will be explained with reference to embodiment figures.

The wood feeding device 16 according to the present invention is used by connecting the rear part of the wood feeding device 16 to the input port of a wood crusher, and the front upper and lower rotating shafts 2 and 7 are linked with a prime mover. The upper moving part of the lower plate conveyor 5a and the lower moving part of the upper plate conveyor 5b are both rotated in the rear direction while reciprocally rotating the upper and lower plate conveyors 5a.
, 5b, the thinning material is inserted into the space between the front faces and is fed in a pinched manner. The upper and lower surfaces of the wood are transferred to the upper and lower plate conveyor 5a.
, 5b, the wood will not fly away even if a reaction force is applied to the wood during crushing, and if the wood has a large diameter, the tip of the upper plate conveyor 5b will pivot around the rear rotating shaft 7''. At the same time, the rear end of the upper plate conveyor 5b also rotates upward along with the arm rods 10 and 1'' about the front rotating shaft 7, so that the clamping and feeding operation is smooth regardless of the diameter of the wood. In addition, even short wood scraps can be crushed by being pinched and fed to the crusher, and there is no slippage of the wood during feeding, making it possible to carry out efficient feeding work. , which has the remarkable effects mentioned above.
