Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically to a coal gangue crusher. Background Technology

[0002] Coal gangue is a solid waste discharged during the coal mining and washing processes. It is a blackish-gray rock with a low carbon content and harder than coal that is associated with coal seams during the coal formation process. It includes gangue from tunneling, gangue extracted from the roof, floor and interlayers during mining, and gangue from coal washing.

[0003] Chinese patent CN221772392U discloses a coal gangue crusher, comprising a casing and a crushing mechanism. The casing has a feed inlet, a receiving cavity, and a discharge outlet connected in sequence. The crushing mechanism includes a crushing structure, a motor, and a screen. The crushing structure includes a hollow shaft and multiple crushing arms. The hollow shaft is rotatably mounted in the receiving cavity, with one end extending to the outside of the casing and connected to the output shaft of the motor via a coupling. The multiple crushing arms are evenly arranged in the receiving cavity around the hollow shaft, with a gap between each crushing arm and the hollow shaft for material to pass through. The screen is detachably mounted at the discharge outlet. When the motor starts, it drives the coupling and the hollow shaft to rotate. Due to the high-speed rotation of the hollow shaft, the material in the gap is crushed by the hollow shaft and the multiple crushing arms. The crushed material falls through the screen at the discharge outlet to the next workstation.

[0004] However, the above solution can only screen crushed coal gangue. Coal gangue itself is a material that is relatively easy to weather and disintegrate by absorbing water. Before processing, the whole pile of coal is usually shoveled into the crushing machine. A large amount of coal gangue that has reached the crushing standard can easily cause a workload on the machine if it is crushed again. In addition, the screen used by this equipment can only be cleaned after it is removed, but the screen mesh is easy to get clogged during the screening process. Frequent cleaning of the screen is not conducive to improving work efficiency. Therefore, it is necessary to design a coal gangue crusher. Utility Model Content

[0005] The purpose of this utility model is to provide a coal gangue crusher that solves the problem in related technologies where only crushed coal gangue can be screened during use. Coal gangue itself is a material that is relatively easy to weather and disintegrate by absorbing water. Before processing, the whole pile of coal is usually shoveled into the crushing machine. A large amount of coal gangue that has reached the crushing standard enters the crushing mechanism for further crushing, which can easily cause a heavy workload on the machine. In addition, the screen used by this equipment can only be removed and cleaned, but the screen mesh is easy to get clogged during the screening process. Frequent cleaning of the screen is not conducive to improving work efficiency.

Larger particles are screened out. When the crushed stone needs to be crushed, the motor three inside the motor box will cause the rotating shaft three and the crushing wheel to rotate and mesh with each other, crushing the stone. The crushed stone falls into the upper part of the second conveyor belt for output, which can save crushing volume and improve crushing efficiency. When cleaning is required, the motor one will be started to rotate the rotating shaft one, which will drive the flip-over filter plate to rotate at the same time. When the flip-over filter plate rotates to the state of being in contact with the rotating shaft two, the motor two will be started to rotate the rotating shaft two. The protrusions on the surface of the rotating shaft two will rotate and knock the flip-over filter plate, causing the blocked stone to fall back into the surface of the first conveyor belt for conveying and crushing.

[0019] 2. The first conveyor belt can be fixed by the inclined U-shaped insert plate. By inserting the limiting insert plates on the upper and lower sides of the insert side plate into the U-shaped cover plate and the bottom plate on the upper and lower sides respectively, the vertical position of the insert side plate on both sides can be fixed, and the U-shaped cover plate can be fixed to maintain the stability of the crusher. By activating the atomizing spray plate, water flow from the water tank can be drawn through the pipeline for atomized spraying to reduce dust during the crushing process.
