Description

An automatic removal device for slag accumulation on a belt conveyor

technical field

The invention relates to the technical field of belt conveyor slag removal, in particular to an automatic belt conveyor slag removal device.

Background technique

In recent years, with the acceleration of my country's infrastructure construction, more and more urban subways and mountain tunnels have been constructed. For the construction of these tunnels, the shield method has become the mainstream trend. When using the shield method for tunnel construction, two The first method is to transport the excavated slag to the slag discharge well by combining the equipment belt conveyor with the marshalling train, and then lift the slag hopper on the marshalling to the designated slag storage pool on the ground by driving , the second is to use the combination of equipment belt conveyor and continuous belt conveyor to transport the excavated slag to the slag discharge well, and then transport the slag to the designated slag storage tank on the ground through the belt conveyor.

The method of slag discharge by crane hopper is relatively mature, and it can transport different types of muck, but the transportation efficiency is low, and it needs to occupy more space to arrange cranes and other equipment, which affects the overall construction period of shield tunneling. Therefore, in the face of tunnel construction with long distance and strict construction period requirements and the size of the slag discharge shaft is small, the slag discharge method with belt conveyor is effective. It not only has high conveying efficiency, good construction environment, but also convenient equipment maintenance.

However, the use of belt conveyors for slag discharge also has disadvantages. For example, the belt conveyor has strict requirements on the particle size of the conveying medium, the belt is difficult to clean and the slag in the slag bucket cannot be cleaned, and the downlink of the output port of the belt conveyor The belt will drop slag, and the slag will accumulate under the belt conveyor. The slag accumulated below will cause problems such as slow running speed and difficult cleaning of the slag. The existing slag removal technical scheme of the belt conveyor can only clean the slag on the belt, but cannot clean the slag accumulated under the belt conveyor. Periodic slag cleaning is required manually to ensure the normal operation of the belt conveyor. Therefore, there is an urgent need for a device to solve the problem that the slag accumulated under the belt conveyor is difficult to clean up.

Contents of the invention

In view of the shortcomings in the above-mentioned background technology, the present invention proposes an automatic removal device for slag accumulation on a belt conveyor, which solves the problem that the slag accumulation under the existing belt conveyor is difficult to clean.

The technical solution of the present invention is realized in the following way: an automatic slag removal device for a belt conveyor, including a belt conveyor, the belt conveyor includes a drive roller that drives the slag delivery belt to rotate, and the drive roller can drive the slag delivery belt to circulate turn. The drive roller includes a first roller and a second roller, the second roller is located at the slag outlet at the top of the belt conveyor, the first roller is located below the second roller, and the slag feeding belt is driven by the first roller and the second roller, The slag below can be transported to the top through the slag conveyor belt. The side of the slag-feeding belt away from the first drum and the second drum is provided with a slag-stopping plate, which can ensure that the slag on the slag-feeding belt will not fall during the upward conveying process. A driven belt bracket is arranged opposite to the left and right of the first drum, and a redirection wheel set is arranged on the driven belt bracket, and a fourth redirection wheel is arranged at a position far away from the first drum and corresponding to the upper and lower sides of the slag outlet.
