The protrusion wheel 44 is pivoted on the mounting frame 43 with the drums close to each other by being shifted by 1/2 of the protrusion mounting pitch, as shown in FIGS. 3a and 3b, so that the protrusions do not come into contact with each other. .

The chip manufacturing machine of this invention is constructed as described above, and the procedure for manufacturing chips using this manufacturing machine will be described below.

Although not shown, when the wood for chips A is sent on a belt conveyor installed in front of this chip making machine and transferred from between the supports 41 onto the conveyor 23, the fluid cylinder 46 is operated depending on the amount of wood. A plurality of protruding wheels 4 are pivotally supported on the mounting frame 43 by varying the angle of inclination of the arm rod 42 with respect to the floor material 21.
4 and the belt conveyor 23,
The lumber a piled up between the conveyor 23 and the pair of guide side walls 24 is moved to
4 in the counterclockwise direction, that is, in a direction that prevents the wood a from advancing, the order of the wood a to be conveyed is given priority to the lowest wood that is in direct contact with the belt conveyor 23, and a large load is placed on the cutter mechanism 39. It is possible to avoid giving

That is, before the large number of pieces of wood a stacked on the conveyor 23 are carried into the cutter mechanism 39, the plurality of protruding wheels 44 are arranged so as to be inclined at approximately the same angle as the inclination angle of the disc body 391 with cutting blades. Said rotation of 44 limits its advancement.

Therefore, the number of pieces of wood cut by the cutter mechanism 39 may vary from a few pieces as shown in Figure 2a to several dozen pieces as shown in Figure 2b, and the size and hardness of the pieces of wood may vary. Even if the lumber is different, the feed amount of each lumber can be adjusted by changing the rotation speed of the protruding wheel 44 by the motor 451, and the flying off due to the large impact received by the lumber when it is cut by the cutter mechanism 39 can be reduced. Can be done.

In this case, since the arm rod 42 of the mounting frame 43 to which the protruding wheel 44 and the motor 451 are attached is connected to the spring 47 via the traction cord 49, even if the wood a suddenly moves downward, the elasticity of the spring 47 will Sudden downward movement of the mounting frame 43 can be prevented.
