[0003] In the mining process of traditional coal mining equipment, key parts such as tooth cutters are frequently worn, but the existing equipment lacks a convenient part replacement mechanism. Workers need to spend a lot of time and energy to disassemble and install, which not only increases the labor intensity, but also causes the equipment to shut down for a long time, seriously affecting the overall progress of coal mining and increasing the mining cost. In addition, in the process from coal mining to subsequent processing, the crushing equipment has limited crushing capacity for large coal blocks, and it is difficult to crush them to a suitable particle size, which makes the subsequent crushing mechanism overloaded and the processing efficiency low, unable to meet the needs of efficient production in coal mines. Moreover, during the transportation of coal, due to the lack of effective collection and guiding devices, coal blocks are easily scattered, which not only increases the cleaning cost, but also reduces the continuity of production.

A closed cover 3 502 is installed inside the feeding bin 1, and a motor 3 503 is installed inside the closed cover 3 502.

A rotating shaft 506 is installed on the output end of the hydraulic rod 2 505, and a roller 507 is installed inside the rotating shaft 506.

[0030] Specifically, the crushing mechanism 5 is responsible for crushing larger coal blocks in the electromechanical equipment of the coal mine, and reducing the pressure of the subsequent crushing mechanism. The fixed seat 501 in the crushing mechanism 5 is fixed to the side surface of the feeding bin 1 to provide a mounting position for the crushing mechanism. The closed cover 3 502 is installed in the feeding bin 1 to protect the motor 3 503 from dust and coal dust. The motor 3 503 is in the closed cover 3 502, and the output power drives the fixed seat 501 to rotate to adjust the angle of the mounting seat 2 504 and the hydraulic rod 2 505. The mounting seat 2 504 is fixed to the outer surface of the fixed seat 501, providing installation and rotation support for the hydraulic rod 2 505, so that the hydraulic rod 2 505 can adjust the position and angle of the rotating shaft 506 and the roller 507.

[0031] The crushing mechanism 4 includes a conveyor belt 401, which is installed inside the feeding bin 1. A transport port 402 is opened on the outer surface of the feeding bin 1.

The elevator 403 is installed in the feeding bin 1 and penetrates the transportation port 402 and is adjacent to the conveyor belt 401. When the conveyor belt 401 transports the coal blocks to the vicinity, the elevator 403 is started, the coal blocks are lifted and transported out, and the position of the coal is changed so that it can enter the collection bin 404.

[0033] A shovel plate 6 is installed on one side of the feeding bin 1 close to the lifting block 202 , and a rake claw 7 is installed on the upper surface of the shovel plate 6 .

[0034] Specifically, the shovel plate 6 is used to collect the coal blocks, and the rake claw 7 is used to assist the coal blocks to enter the subsequent components.

[0035] A water tank 8 is provided on the upper surface of the feeding bin 1, and the water tank 8 is arranged between the lifting block 202 and the transport port 402. A small hole 9 is opened on the lower surface of the water tank 8, and a spray hole 10 is opened on the upper surface of the feeding bin 1. The spray hole 10 corresponds to the small hole 9, and a baffle 11 is installed inside the spray hole 10.

[0036] Specifically, the water tank 8 is used to store liquid, and the small hole 9, the spray hole 10 and the baffle 11 cooperate with each other to adjust the speed of the water spray.

[0037] The outer surface of the roller 507 is provided with spikes 12 .

[0038] Specifically, the spikes 12 are used to break up coal lumps.

[0039] A crawler belt 13 is provided at the lower part of the feeding bin 1 .

[0040] Specifically, the crawler track 13 is used to disperse the weight of the equipment and provide grip.

[0041] Working principle: In coal mining operations, after the equipment is started, the crawler 13 drives the equipment to the working area, and then the mining mechanism 2 is started. First, the hydraulic rod 1 208 extends, pushing the lifting block 202 to rotate around the side surface of the fixed plate 201, driving the mining rod 203, the liquid storage tank 311 and the hydraulic rod 3 331 installed thereon to rise to a suitable height to prepare for the mining operation. Subsequently, the drill bit 204 on the mining rod 203 is driven to rotate at a high speed, and the tooth cutter 206 is in direct contact with the coal. , relying on the sharp edge of the toothed cutter 206 and the rotational force of the drill bit 204, the coal is cut from the rock mass. During the mining process, if the toothed cutter 206 is worn, the replacement mechanism 3 can be started to replace the toothed cutter 206; when replacing the toothed cutter 206, the hydraulic rod 331 is extended, pushing the fixing ring 332 and the connecting parts to move, so that the working cover 321 slides on the mining rod 203 to the vicinity of the drill bit 204, and then the motor 2 334 rotates to drive the steel cable 335 to contract, so that the working cover 321 opens and wraps the drill bit 204. The head 204 is connected to the torsion sleeve 323 inside the torsion sleeve 323 and the tooth seat 205, and the hexagonal groove 328 inside the torsion sleeve 323 is meshed with the hexagonal protrusion outside the tooth cutter 206. Then the motor 1 325 is started, and the gear 326 at its output end drives the gear ring 327 to rotate the torsion sleeve 323, and the hexagonal groove 328 is meshed with the hexagonal protrusion, so that the damaged tooth cutter 206 is separated from the tooth seat 205, and then the supply mechanism 31 is started. Since a new tooth cutter 206 is placed in advance in the delivery hose 313, , the liquid in the liquid storage tank 311 is sent into the delivery hose 313 through the liquid pump 312, driving the new tooth knife 206 inside to move to the torsion sleeve 323 to push out the removed damaged tooth knife 206, and then reverse the motor 1 325, tighten the new tooth knife 206, and complete the replacement; during the replacement process, the motor 2 334 can pull the working cover 321 through the steel cable 335, and combine the cooperation of the rotating rod 337 and the base 336 to flexibly adjust the opening and closing angle of the working cover 321 to ensure that the replacement operation is carried out smoothly.

[0042] The mined coal blocks will fall on the outside of the roller 507. If the volume of the coal block is too large, the crushing mechanism will be started, and the motor 3 503 will drive the fixed seat 501 to rotate to adjust the angle of the hydraulic rod 2 505, and then the hydraulic rod 2 505 can adjust the position and angle of the rotating shaft 506 and the roller 507. The spikes 12 on the outer surface of the roller 507 can effectively insert the coal block. During the rotation of the roller 507, the larger coal block is broken into smaller blocks, reducing the working pressure of the subsequent crushing mechanism.

[0043] The crushed coal blocks are transported to the shovel plate 6. The rake claws 7 on the shovel plate 6 can prevent the coal blocks from rolling down, and facilitate their introduction into the feeding bin 1. In the feeding bin 1, the conveyor belt 401 transports the coal blocks to the elevator 403. The elevator 403 lifts the coal blocks through the transport port 402 and transports them to the collecting bin 404. The guide plate 405 on the collecting bin 404 guides the coal blocks to smoothly enter the collecting bin 404. In the collecting bin 404, the crushing wheel 406 rotates at high speed to crush the coal blocks so that their particle size meets the requirements of subsequent processing. The slope plate 407 in the collecting bin 404 helps the crushed coal to slide smoothly in the collecting bin 404.

[0044] In addition, when a large amount of dust is generated during the process of transporting coal blocks to the collection bin 404, the baffle 11 can be opened to allow the water in the water tank 8 to be sprayed out through the small holes 9 and the spray holes 10 to reduce dust in the working area, improve the working environment, reduce the harm of dust to equipment and operators, and soften the coal blocks for subsequent crushing.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
