Manufacturing method of gangue bin funnel wall protection device

Abstract

The invention discloses a manufacturing method of a gangue bin funnel wall protection device. The device comprises a funnel, a mounting ring and a control panel, the top of the outer side of the funnel is provided with a splicing disc, the bottom of the funnel is provided with mutually communicated material guide pipes, and two sides in each material guide pipe are provided with through holes A; and reinforcing plates which are connected with one another are uniformly arranged at the bottom of the mounting ring. Through mutual cooperation of the fitting buffer assemblies, a protective frame matched with the funnel can be assembled outside the funnel, and a self-adaptive buffer assembly aiming at the impact on the surface of the funnel is formed according to extrusion fitting of a fitting plate, rubber buffer cotton and a concave layer in the frame, so that vibration and loss of the inner wall of the funnel caused by gangue discharging are reduced, the protection characteristic of the outer wall of the funnel is further improved under welding reinforcement of the multiple sets of reinforcing plates and the connecting rings, and damage caused by external factors and gangue conveying to the inner wall and the outer wall of the funnel is greatly prevented.

Description

technical field [0001] The invention relates to the technical field of gangue bins, in particular to a manufacturing method for a funnel wall protection device for gangue bins. Background technique [0002] The stones mixed in the coal seam contain a small amount of combustibles and are not easy to burn. They are commonly known as "gangue". . The pile of gangue on the ground of the mine is called "gangue mountain". When conveying or screening materials for gangue, it is often necessary to use a funnel for auxiliary feeding; [0003] When the current funnel is in use, due to the large gravity of the gangue body, the inner wall of the funnel will produce a large impact and vibration every time it touches the gangue. With the long-term use of the funnel, it is easy to cause the inner wall of the funnel to rupture, resulting in gangue during transportation. Stuck, greatly delaying the work efficiency of the operator, increasing the difficulty and inconvenience of the operation...

Problems solved by technology

[0003] When the current funnel is in use, due to the large gravity of the gangue body, the inner wall of the funnel will produce a large impact and vibration every time it touches the gangue. With the long-term use of the funnel, it is easy to cause the inner wall of the funnel to rupture, resulting in gangue during transportation. Stuck, greatly delaying the work efficiency of the operator, increasing the difficulty and inconvenience of the operation of the staff, when the funnel is used, most of the funnels are installed in a conical structure, but the gangue is supported by the structure of the conical guide It is easy to cause blockage at the discharge port. The outer surface of the common funnel is clean and smooth, and it is not convenient to install a treatment structure for material blockage, which makes the gangue funnel unable to adapt to the work needs of the operator and reduces the practical value of the device.
