Description

Technical Field

[0001] The present invention relates to the technical field related to coal mining, and in particular to a fully mechanized coal mining mechanism for a working face. Background Art

[0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. They are generally divided into underground and open-pit mines. The vast majority of coal mines in my country are underground mines. Coal mines encompass large areas both above and below ground, as well as related facilities. Coal mines are the spaces humans create when excavating coal-rich geological strata, typically consisting of tunnels, shafts, and mining faces. Coal is the primary solid fuel and a type of combustible organic rock. It is formed by the natural coalification process over long geological periods, when lush vegetation grows over a certain geological period, gradually accumulating into thick layers in a suitable geological environment and then being buried under water or in mud. Among the various geological periods worldwide, the Carboniferous, Permian, Jurassic, and Tertiary periods have the highest coal production, representing important coal-forming periods.

[0003] Traditional coal mining mechanisms generally use multiple coal mining shovels to rotate in a circular motion to mine coal. During operation, this method of coal mining cannot handle relatively hard objects well. If the coal mining shovel directly collides with the hard objects, it is easy to cause wear and tear of the coal mining shovel, affecting its normal service life. In more serious cases, the coal mining shovel may be deformed and cannot perform coal mining operations normally. Summary of the Invention

[0004] The present invention provides a fully mechanized coal mining mechanism for a working face, which solves the problems in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A fully mechanized coal mining mechanism for a fully mechanized working face, comprising a bottom plate and:

[0007] The cam is fixedly provided with a toothed plate on the bottom surface of the base, and a toothed plate is fixedly provided with a toothed plate on one side of the base, and a toothed plate is fixedly provided with a toothed plate on the other side of the base, wherein the toothed plate is fixedly provided with a toothed plate on the bottom surface of the base, and a toothed plate is fixedly provided with a toothed plate on the other side of the base

[0008] As a preferred technical solution of the present invention, the coal mining assembly includes a support member fixedly arranged on one side of the inner wall of the fixed cylinder, one end of the support member is fixedly connected to a sealing block, the sealing block is slidably arranged in the fixed cylinder, one side of the sealing block is fixedly connected to a telescopic column, one end of the telescopic column is slidably connected to the side wall of the fixed cylinder, and the end of the telescopic column is fixedly connected to a mining shovel.

[0009] As a preferred technical solution of the present invention, the pneumatic component includes fixed arms fixedly arranged on both sides of the top of the coal mining shell, a rotating column fixedly connected between the fixed arms, an air cylinder rotatably sleeved on the rotating column, a piston column slidably arranged at one end of the air cylinder, and a telescopic tube fixedly connected between the air cylinder and the air guide pipe.

[0010] As a preferred technical solution of the present invention, the end of the piston column is fixedly connected to the impact hammer, one end of the coal mining shell is hinged to the electric telescopic rod, and one end of the electric telescopic rod is hinged to the outer wall of the gas cylinder. The angle of the impact hammer can be adjusted by extending and retracting the electric telescopic rod, thereby achieving precise crushing of objects.

[0011] As a preferred technical solution of the present invention, the air inlet groove is connected to the air transfer groove, the inner wall of the end of the air inlet groove is rotatably connected to the valve plate, the inner wall of the air inlet groove on one side of the valve plate is fixedly connected to the stop block, the inner wall of the air inlet groove on one side of the valve plate is fixedly connected to the positioning block, and a telescopic part is arranged between the positioning block and the valve plate.

[0012] As a preferred technical solution of the present invention, the mounting plate is fixedly connected to a dust collector away from a side wall of the coal mining shell, and the air inlet end of the dust collector is fixedly connected to a conduit. One end of the conduit passes through the mounting plate, and the end is fixedly connected to a dust suction pipe. During the coal mining process, the dust collector absorbs external dust through the dust suction pipe, thereby improving the environment at the coal mining site.

[0013] As an optimal technical solution of the present invention, a through opening is opened on the bottom wall of the coal mining shell, crawler wheels are set at the bottom of the bottom plate, and a collection box is fixedly connected to the bottom plate below the through opening. During operation, the material eventually enters the collection box through the through opening to realize coal mining and collection.

[0014] The present invention has the following advantages: during actual operation, the rotation of the mounting roller drives the coal mining shovel on the side to rotate, and contacts the coal seam to realize coal mining. If a relatively hard object is encountered during the rotation, the mounting frame will be deflected due to the resistance of the object. During the rotation, the air pump located on one side of the mounting frame is in contact with and connected to the air inlet groove. The air pump sends high-pressure gas into the air inlet groove and into the telescopic tube at one end of the air guide pipe through the air transfer groove. Then the air cylinder is filled with high-pressure gas, which drives the piston column to extend, and the object is hit under the action of the impact hammer. If the object is broken, the mounting frame rotates and resets under the action of the elastic member, and the coal mining shovel follows the mounting roller to continue Continue to rotate to mine coal. If the object is not broken, the mounting frame continues to rotate, and the air pump is connected to the next air inlet groove and then hits the object again. If the object is not broken, the mounting frame continues to rotate to connect the air pump to the air guide groove, and high-pressure gas is sent into the hose. The sealing block in the fixed cylinder drives the telescopic column to move and retract the coal shovel. This method can effectively protect the coal shovel. Then the mounting roller continues to rotate, and the above steps are repeated when the next coal shovel contacts the object until the object is broken. Generally speaking, the device is easy to operate and use, can protect the coal shovel while mining coal, improves the safety of the device, has a longer service life, and is more practical.
