AI Technical Summary
In traditional crushers, some material flows towards both ends and adheres to the side walls of the crusher body when crushing materials, resulting in reduced crushing efficiency.
By adding guide wheels to both ends of the main shaft of the crusher, the guide teeth on the guide wheels help the material to move closer to the center, thereby improving the crushing efficiency.
The design of the guide wheel promotes the material to move towards the center, which significantly improves the crushing efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of crusher technology, and in particular to a crusher. Background Technology
[0002] A crusher is a common piece of equipment in the solid waste treatment and crushing industry. Its main structure consists of two or more main shafts driven by a motor. The material is reduced in size through shearing, squeezing, and tearing by the blades on the main shafts. Crushers can be used to crush various materials such as wood, plastics, tires, scrap metal, and household waste.
[0003] When traditional crushers crush materials, some materials tend to flow towards both ends and adhere to the side walls of the crusher. In this case, the material at both ends is not easily crushed, resulting in reduced crushing efficiency. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a crusher in which guide wheels are installed at both ends of the main shaft. As the main shaft rotates, the materials at both ends can be guided towards the center, thereby improving crushing efficiency.
[0005] The technical solution of this utility model is as follows:
[0006] A crusher includes a housing with two parallel main shafts inside. Each main shaft has a plurality of cutters, and the cutters on the two main shafts are arranged alternately. A comb plate is provided on the inner wall of the housing between two adjacent cutters. A drive motor for driving the two main shafts is provided on the outer side of the housing. A set of guide wheels is provided between the two sets of cutters at both ends and the inner wall of the housing. Each set of guide wheels includes two wheels, which rotate in opposite directions. The outer edge of the guide wheels is provided with spirally extending inward guide teeth.
[0007] The working principle of the above technical solution is as follows:
[0008] This invention adds a set of guide wheels at both ends of the box body. During the crushing process, the material flowing to both ends will be pushed inward by the guide teeth on the guide wheels as they rotate, promoting the material at both ends to move closer to the center, which can effectively improve the crushing efficiency.
[0009] In a further technical solution, the guide wheel is a ring structure and is rotatably connected to the inner wall of the box. The main shaft passes through the inner ring of the guide wheel, and the bottom of the box is provided with a drive assembly for driving the guide wheel to rotate.
[0010] In a further technical solution, the driving component is a driving wheel that fits against 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 cutting tool has a ring structure and is detachably connected to the spindle.
[0012] In a further technical solution, the top of the comb plate has a slope that slopes downward toward the inside of the box.
[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 shaft. The circuit board is provided with a wound coil and is a PCB printed circuit board. The rotor is provided with a magnet. The rotor and the circuit board are arranged opposite to each other, and the rotor is fixedly connected to the shaft.
[0015] The beneficial effects of the utility model are:
[0016] 1. This utility model adds a set of guide wheels at both ends of the box body. During the crushing process, the material flowing to both ends will be pushed inward by the guide teeth on the guide wheels as they rotate, promoting the material at both ends to move closer to the center, which can effectively improve the crushing efficiency.
[0017] 2. This utility model uses a circuit board motor as the drive motor of the main shaft and a PCB printed circuit board as the motor stator. The overall structure is compact, small in size, light in weight, and has a wide speed range, which makes it more portable and can further improve the working efficiency of the chainsaw.

[0021] The embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0022] Example:
[0023] A type of crusher, such as Figure 1As shown, the device includes a housing 10, inside which are two parallel spindles. Each spindle is equipped with several cutting tools 20, and the cutting tools 20 on the two spindles are arranged alternately. A comb plate 30 is provided on the inner wall of the housing 10 between two adjacent cutting tools 20. A drive motor 40 for driving the two spindles is provided on the outer side of the housing 10. A set of guide wheels 50 is provided between the two sets of cutting tools 20 at both ends and the inner wall of the housing 10. Each set of guide wheels 50 includes two wheels, which rotate in opposite directions. The outer edge of the guide wheel 50 is provided with spirally extending inward guide teeth 51.
[0024] In this invention, a set of guide wheels 50 are installed at both ends of the housing 10. During the crushing process, the material flowing to both ends will be pushed inward by the guide teeth 51 on the guide wheels 50 as they rotate, which will help the material at both ends to move closer to the center and effectively improve the crushing efficiency.
[0025] In another embodiment, the guide wheel 50 has an annular structure and is rotatably connected to the inner wall of the housing 10. The main shaft passes through the inner ring of the guide wheel 50, and the bottom of the housing 10 is provided with a drive assembly for driving the guide wheel 50 to rotate.
[0026] In another embodiment, the driving component is a driving wheel that fits against the outer edge surface of the guide wheel 50, and the outer edge surface of the driving wheel is provided with a driving groove that cooperates with the guide tooth 51.
[0027] In another embodiment, the tool 20 is a ring structure and is detachably connected to the spindle.
