Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pneumatic track stockyard cleaner, in particular to the pneumatic track stockyard cleaner for coal mine. BACKGROUND

[0002] In the daily production and operation of coal mine, the coal bunker plays a crucial role, mainly used for temporary storage of coal and adjusting the rhythm of coal conveying. However, the inside of the coal bunker, especially the bottom and the inner wall, is easily affected by the continuous loading and unloading, accumulation and moisture of coal, and the coal adheres, accumulates and gradually forms a sludge-like material, that is, the coal bunker is silted. If these silt is not cleaned in time, it will occupy the effective volume of the coal bunker, resulting in a decrease in the storage capacity of coal, and may also block the discharge port, so that the coal cannot be smoothly discharged, thereby causing the failure of the entire coal conveying system, seriously affecting the continuity of coal production, which requires the use of pneumatic track stockyard cleaner.

[0003] Early, it is mainly relied on manual entry into the coal bunker for dredging, and workers carry simple tools for operation. This dredging method is extremely low in efficiency, and it needs to invest a large amount of manpower and time cost. With the development of science and technology, mechanical stockyard cleaner gradually begins to face the market. However, the existing mechanical stockyard cleaner still has the following problems: 1. The traditional track structure often lacks effective self-adaptive adjustment mechanism. When encountering large terrain or irregular gangue accumulation, the track cannot be well fitted with the ground, and local suspension may occur, making the equipment unstable, and the chassis and other parts of the equipment may be impacted, and long-term use may also cause damage to the parts. In addition, the frequent shaking and jamming of the equipment during the dredging process are also not conducive to the accurate positioning and cleaning of the silt in each corner of the coal bunker; 2. The width of the silt extraction port is fixed and small. For large-area and thin silt layer, the cleaning efficiency will be very low, because only a small range of silt can be extracted each time, and multiple repeated operations are needed to cover a large area, which is low in extraction efficiency.

[0004] Therefore, it is urgent to provide a pneumatic track stockyard cleaner for coal mine to solve the above problems. SUMMARY
