The present invention solves the above problems and can achieve the following effects.
1. Overall processing time is short and the cost is low. That is, the entire combination type rotary cutter is integrated with the adjacent cutter table disks locked together, and one cutter table disk is a disk having a thickness of several centimeters, and therefore can be manufactured with a normal processing tool. Further, since the processing of the locking recess is extremely simple, the entire processing is easy, the processing time is short, and the cost is low.

2. High rotational cutting effect can be obtained. That is, the combined rotary cutter of the present invention is heavy and has a large inertia, so that a large kinetic energy can be obtained during high-speed rotation. Further, the rotating cutters of the adjacent cutter base disks are shifted from each other by a constant angle, and after all, cutting is performed alternately and large sawdust can be produced, so that a high cutting effect is obtained.

3. Easy maintenance. If one rotating cutter breaks down, only the broken cutter can be taken out and replaced, making maintenance very easy.

4). Wide application range. Since the cutting effect of the present invention is high, it is possible to cut hard wood such as cocoons, tree trunks, branches, wooden scrapboards and wooden furniture in addition to general wood. Furthermore, it can be applied to a wide range of fields such as agriculture, industry and environmental business.

5. The width of the crushed tree can be adjusted flexibly. Since the crushed work width W of the combined rotary cutter 30 of the present invention (refer to FIG. 3, also referred to as the width of the crushed tree) is determined by the number of cutter table disks 31, the relatively large combined timber crushing When the machine is manufactured, the lengths of the carriage 10 and the drive shaft 20 may be increased, and at the same time, a large number of cutter base disks 31 may be assembled (enlargement of the crushing work width W). On the other hand, it can be easily modified to a small-sized combination wood crusher (reduction of the crushing work width W). Therefore, it is possible to flexibly adjust the crushed work width of the combined wood crusher.
