Description

An underground coal gangue crushing and separating machine

(1) Technical field

The utility model relates to a mining tool, in particular to an underground coal gangue crushing and separating machine.

(2) Background technology

Existing coal gangue crushers generally work on wells. The crusher occupies a large area of land, and the coal gangue needs to be transported to the ground, which requires transportation costs. The crusher also produces a large amount of powder during work to pollute the environment.

(3) Contents of the invention

In order to make up for the deficiencies of the prior art, the utility model provides an underground coal gangue crushing and separating machine which saves land occupation area, reduces transportation costs and reduces environmental pollution.

The utility model is achieved through the following technical solutions:

An underground coal gangue crushing and separating machine, including a drum and an explosion-proof motor, characterized in that: the drum is provided with a spiral drive plate and a lifting plate, and three counter-attack impact hammers located on the same central axis are installed at the center of the drum. Equipped with evenly distributed sieve holes.

Therefore, the beneficial effects of the utility model are: the underground coal gangue crushing and separating machine has a simple structure, saves land occupation area, reduces transportation costs, and reduces environmental pollution.

(4) Description of drawings

Below in conjunction with accompanying drawing, the utility model is further described.

Accompanying drawing 1 is the structural representation of the utility model;

Accompanying drawing 2 is the schematic cross-sectional view of the drum of the utility model.

In the figure, 1 roller, 2 lifting plate, 3 impact hammer, 4 screw drive plate, 5 rotating shaft, 6 feeding port, 7 discharging port.

(5) Specific implementation methods

Accompanying drawing is a kind of concrete embodiment of the utility model. This embodiment includes a drum 1 and an explosion-proof motor, and is characterized in that: the drum 1 is provided with a screw drive plate 4 and a lifting plate 2, and the center of the drum 1 is equipped with three impact hammers 3 located on the same central axis, and the drum 1 The whole is equipped with evenly distributed sieve holes.

With the underground coal gangue crushing and separating machine of the utility model, both the drum 1 and the central shaft are driven to rotate by an external explosion-proof motor, and the surface of the drum 1 is evenly distributed with sieve holes so that the crushed coal particles can be screened out, and the gangue is fed from the feeder. The feed port 6 is sent into the drum 1, driven by the screw drive plate 4 to the right, and then lifted to the top of the drum 1 by the lifting plate 2 and falls freely, the impact hammer 3 rotates in the opposite direction with the drum 1 The generated impact force breaks the free-falling coal gangue, and the coal with low hardness falls to the bottom of the drum 1 after being crushed, and is discharged through the screen holes of the drum 1, while the remaining materials are continuously driven to the right by the screw drive plate 4. The next round of impact is crushed, so that through the impact of the three-wheel impact hammer 3, the coal particles are screened out by the screen holes on the drum 1, and the large pieces of coal gangue are discharged by the discharge port 7. The drum 1 runs slowly to convey the material, while the impact hammer 3 runs in the opposite direction at a high speed to impact the material sliding down the lifting plate 2. For coal blocks with different hardness, the impact force can be adjusted by adjusting the speed of the impact hammer 3 to meet different crushing requirements. . Therefore, the beneficial effects of the utility model are: the underground coal gangue crushing and separating machine has a simple structure, saves land occupation area, reduces transportation costs, and reduces environmental pollution.
