Description

Technical Field

[0001] The present invention relates to the technical field of crushers, in particular to a crusher. Background Art

[0002] Crusher is a general equipment in the solid waste treatment and crushing industry. Its main structure is composed of two or more main shafts, which are driven by motors. The cutters on the main shafts shear, squeeze and tear to reduce the size of the materials. Crusher can be used to crush various materials such as wood, plastic, tires, scrap iron and domestic garbage.

[0003] When a traditional crusher crushes materials, some of the materials will flow to the two ends and stick to the side walls of the box. At this time, the materials at the two ends are not easy to be crushed, resulting in reduced crushing efficiency. Summary of the invention

[0004] In view of the above problems, the present invention provides a crusher with guide wheels installed at both ends of the main shaft. As the main shaft rotates, the materials at both ends can be assisted to move closer to the center, thereby improving the crushing efficiency.

[0005] The technical solution of the present invention is as follows:

[0006] A crusher comprises a box body, wherein two parallel main shafts are arranged in the box body, each of the main shafts is respectively provided with a plurality of cutters, and the cutters on the two main shafts are arranged alternately in sequence, a comb plate is provided on the inner wall of the box body between two adjacent cutters, and a driving motor for driving the two main shafts is provided on the outer side of the box body; a group of guide wheels is respectively provided between the two groups of cutters located at both ends and the inner wall of the box body, each group of guide wheels comprises two guide wheels, the two guide wheels rotate towards each other, and the outer edge surface of the guide wheel is provided with guide teeth which extend inward in a spiral.

[0007] The working principle of the above technical solution is as follows:

[0008] The present invention installs a set of guide wheels at both ends of the box body respectively. During the crushing process, the materials flowing to the two ends will be pushed inward with the assistance of the guide teeth on the guide wheels during the rotation of the guide wheels, thereby promoting the materials at the two ends to move closer to the center, which can effectively improve the crushing efficiency.

[0009] In a further technical solution, the guide wheel is an annular structure and is rotatably connected to the inner wall of the box body. The main shaft passes through the inner ring of the guide wheel. A driving component for driving the guide wheel to rotate is provided at the bottom of the box body.

[0010] In a further technical solution, the driving assembly is a driving wheel that fits with the outer edge surface of the guide wheel, and the outer edge surface of the driving wheel is provided with a driving groove that cooperates with the guide teeth.

[0011] In a further technical solution, the tool is an annular structure and is detachably connected to the main shaft.

[0012] In a further technical solution, the top of the comb plate has an inclined surface that slopes downward toward the inner side of the box body.

[0013] In a further technical solution, the drive motor is a circuit board motor.

[0014] In a further technical solution, the circuit board motor includes a circuit board, a rotor and a rotating shaft, the circuit board is provided with a winding coil, and the circuit board is a PCB printed circuit board; a magnet is provided on the rotor, the rotor and the circuit board are arranged relative to each other, and the rotor is fixedly connected to the rotating shaft.

[0015] The beneficial effects of the present invention are:

[0016] 1. The present invention installs a set of guide wheels at both ends of the box body. During the crushing process, the materials flowing to the two ends will be pushed inward with the assistance of the guide teeth on the guide wheels during their rotation, so as to promote the materials at both ends to move closer to the center, which can effectively improve the crushing efficiency.

[0017] 2. The present invention adopts a circuit board motor as the driving motor of the main shaft and a PCB printed circuit board as the motor stator. The overall structure is compact, the volume is small, the weight is light, the speed range is large, and it has higher portability, which can further improve the working efficiency of the electric saw.
