Description

Technical Field

[0001] The utility model relates to the technical field of ore crushing, in particular to a mining stripping waste rock crushing mechanism. Background Art

[0002] A mine refers to an independent production and operation unit that mines ores with a certain mining area. Mines include coal mines, metal mines, non-metallic mines, building materials mines, chemical mines, etc. The size of a mine should be consistent with the economically reasonable service life of the mine. Only in this way can we save infrastructure costs and reduce costs. In the mining production process, mining operations consume the most manpower and material resources, occupy the most funds, and are also the production link with the greatest potential for reducing mining costs.

[0003] A large amount of waste rock is generated during mining. In order to reuse the waste rock, it needs to be crushed. At present, when the mine waste rock is crushed, it needs to be transported to the crushing equipment through a conveyor belt. The waste rock is easy to roll down on the conveyor belt due to the inclination of the conveyor belt, and more dust will be generated when the waste rock is crushed. The dust will affect the surrounding working environment and the health of the workers. Utility Model Content

[0004] The purpose of the utility model is to provide a mining waste rock crushing mechanism, which has the advantages of convenient loading, absorbing dust generated by crushing and preventing dust, and solves the problems raised by the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mining waste rock crushing mechanism, comprising a crushing box, a mounting plate and a dust collecting box, wherein symmetrically distributed crushing rollers are rotatably mounted in the crushing box, a discharge pipe is mounted at a lower position on a side end surface of the crushing box, a feed port is provided at an upper position on a side end surface of the crushing box away from the discharge pipe, a cover shell is mounted on the outside of the feed port and is located at the side end of the crushing box, two mounting plates are symmetrically welded to the side ends of the crushing box and are located on the outside of the feed port, symmetrically distributed driving wheels and driven wheels are rotatably mounted between the mounting plates, a conveyor belt is arranged between the driving wheel and the driven wheel, and equidistantly distributed limiting plates are arranged on the conveyor belt, the dust collecting box is mounted on the upper end of the crushing box, a dust suction pipe is mounted on the side end of the dust collecting box, and the dust suction pipe extends into the cover shell.

[0006] When using the mine stripping waste rock crushing mechanism of the utility model,

[0007] The operation of the first driving device can make the driving wheel rotate, so that the conveyor belt can be operated, and the mine waste rock can be added to the conveyor belt. The ore can be transported by the conveyor belt in cooperation with the limiting plate, and the ore can be transported to the crushing box. The operation of the third driving device can make the two crushing rollers rotate, and the mine waste rock can be crushed by the two crushing rollers. After the ore is crushed, it can be discharged from the discharge pipe. In the process of crushing the mine waste rock, the dust generated by the crushing will gush out from the feed port. The operation of the second driving device can make the fan blades rotate at a high speed. The high-speed rotation of the fan blades can generate negative pressure in the bellows and the dust collecting box. The dust gushing out of the feed port can be absorbed by the dust suction pipe, and the absorbed dust can enter the dust collecting box for collection. The air can enter the bellows from the connecting port and can finally be discharged from the air outlet. The dust filter cloth can prevent the dust from being discharged.

[0008] Preferably, a support leg is installed at the lower end of the crushing box, and four support legs are arranged in an array with respect to the crushing box.

[0009] Preferably, a first driving device is installed on the side end of the mounting plate, and the main shaft of the first driving device is connected to the axis of the driving wheel.

[0010] Preferably, an equipment box is provided at the rear end of the crushing box, the rotating shaft of the crushing roller extends to the equipment box and a gear is installed therein, the gears are meshed and connected with each other, a third driving device is provided in the equipment box, and the main shaft of the third driving device is connected to the axis of the gear.

[0011] Preferably, a cleaning port is provided at a side end of the dust collecting box, a cleaning door is installed at the cleaning port, and a handle is installed on the outer surface of the cleaning door.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. Add the mine waste rock to the conveyor belt, through which the ore can be transported. The limiting plate can prevent the ore from rolling off the conveyor belt, so that the ore can be transported to the crushing box, which is convenient for loading.

[0015] 2. When the mine waste rock is crushed, the dust generated by the crushing will gush out from the feed port. The second driving device can make the fan blades rotate at high speed. The high-speed rotation of the fan blades can generate negative pressure in the bellows and the dust collecting box. The dust gushing out of the feed port can be absorbed by the dust suction pipe.
