Moreover, the fine raw coal with a large water content is also easy to adhere to the inner wall of the raw coal bin. If it is not cleaned in time, the phenomenon of blockage of the raw coal bin will occur, which will directly affect the normal progress of the feeding operation of the raw coal bin. Manual maintenance has many inconveniences and is not convenient to meet people's usage requirements. Content of the Utility Model

The driving motor 102 is fixedly installed in the middle of the upper end of the raw coal bunker main body 101. The driving rod 103 is fixedly installed at the transmission end of the lower end of the driving motor 102. The connecting rod 104 is fixedly installed at the outer end of the driving rod 103;

[0026] The main body mechanism 1 further includes an arc-shaped ash cleaning plate 105, a vertical electric rail 106, a driving carriage 107 and an annular ash cleaning plate 108. The arc-shaped ash cleaning plate 105 is fixedly installed at the outer end of the connecting rod 104. The vertical electric rail 106 is fixedly installed at the right end of the raw coal bunker body 101. The driving carriage 107 is movably installed inside the vertical electric rail 106. The annular ash cleaning plate 108 is fixedly installed at the lower end of the driving carriage 107. When the driving motor 102 operates to drive the driving rod 103 to rotate, the driving rod 103 drives the connecting rod 104 to rotate, and the connecting rod 104 drives the arc-shaped ash cleaning plate 105 to rotate to clean the coal ash adhering to the inner wall of the raw coal bunker body 101. The staff can drive the driving carriage 107 to move up and down by operating the vertical electric rail 106, and the driving carriage 107 drives the annular ash cleaning plate 108 to move up and down, so as to fully clean the coal ash on the inner wall of the raw coal bunker body 101 and avoid the situation that the raw coal bunker body 101 is blocked due to the accumulation of coal ash.

[0027] The driving mechanism 2 includes a feed inlet 201 and a fixed bottom plate 202. The feed inlet 201 is fixedly arranged at the front end of the raw coal bunker body 101, and the fixed bottom plate 202 is fixedly installed at the lower end of the raw coal bunker body 101. The driving mechanism 2 further includes an electric slide rail 203 and an electric slider 204. The electric slide rail 203 is fixedly installed at the front and rear ends of the upper end of the fixed bottom plate 202, and the electric slider 204 is movably installed inside the electric slide rail 203. The driving mechanism 2 further includes a sealing bottom plate 205, and the sealing bottom plate 205 is fixedly installed at the lower end of the electric slider 204. The sealing bottom plate 205 is movably connected to the raw coal bunker body 101. The driving mechanism 2 further includes a hydraulic cylinder 206 and an adjusting rod 207. The hydraulic cylinder 206 is fixedly installed at the upper end of the fixed bottom plate 202, and the adjusting rod 207 is fixedly installed at the transmission end of the upper end of the hydraulic cylinder 206. The driving mechanism 2 further includes a hammering frame 208, and the hammering frame 208 is fixedly installed at the upper end of the adjusting rod 207.

The stirring blades 209 are evenly distributed at the outer end of the driving rod 103. When using the raw coal bunker body 101 for raw coal feeding operation, the raw coal enters the inside of the raw coal bunker body 101 through the feed inlet 201 for storage. The staff operates the electric slide rail 203 to drive the electric slider 204 to move to the right. The electric slider 204 drives the sealing bottom plate 205 to move to the right, separating it from the raw coal bunker body 101. At this time, the discharge port at the bottom of the raw coal bunker body 101 is in an open state, so that the raw coal falls under the action of gravity. The hydraulic cylinder 206 works to push the hammering frame 208 into full contact with the raw coal bunker body 101, hammering the raw coal bunker body 101, so that the raw coal inside the raw coal bunker body 101 is dispersed by the force. In the reciprocating drive of the hydraulic cylinder 206, the stability of the feeding operation of the raw coal bunker body 101 is improved. When it is necessary to stop the feeding operation, the staff operates the electric slide rail 203 to make the electric slider 204 drive the sealing bottom plate 205 to move to the left, so that the sealing bottom plate 205 is in full contact with the raw coal bunker body 101 to protect the discharge port of the raw coal bunker body 101.

[0028] Working principle: When using the raw coal bunker body 101 for raw coal feeding operation, the raw coal enters the interior of the raw coal bunker body 101 through the feed inlet 201 for storage. The staff operates the electric slide rail 203 to drive the electric slider 204 to move to the right. The electric slider 204 drives the sealing bottom plate 205 to move to the right, separating it from the raw coal bunker body 101. At this time, the discharge port at the bottom of the raw coal bunker body 101 is in an open state, allowing the raw coal to fall under the action of gravity. The driving motor 102 works to drive the driving rod 103 to rotate. The driving rod 103 drives the stirring blade 209 to rotate, agitating the raw coal inside the raw coal bunker body 101 to make the raw coal feeding smoother. At the same time, the driving rod 103 drives the connecting rod 104 to rotate, and the connecting rod 104 drives the arc-shaped ash cleaning plate 105 to rotate to clean the coal ash adhering to the inner wall of the raw coal bunker body 101. The staff operates the vertical electric rail 106 to drive the driving carriage 107 to move up and down. The driving carriage 107 drives the annular ash cleaning plate 108 to move up and down to achieve full cleaning of the coal ash on the inner wall of the raw coal bunker body 101, avoiding the situation of blockage of the raw coal bunker body 101 caused by coal ash accumulation. The hydraulic cylinder 206 works to push the hammering frame 208 into full contact with the raw coal bunker body 101 to hammer the raw coal bunker body 101, making the raw coal inside the raw coal bunker body 101 disperse the force. In the reciprocating drive of the hydraulic cylinder 206, the stability of the raw coal bunker body 101 feeding operation is improved. When it is necessary to stop the feeding operation, the staff operates the electric slide rail 203 to make the electric slider 204 drive the sealing bottom plate 205 to move to the left, so that the sealing bottom plate 205 is in full contact with the raw coal bunker body 101 to protect the discharge port of the raw coal bunker body 101.

[0029] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than a limitation on the protection scope of the present invention. Any simple modification or equivalent replacement of the technical solution of the present invention by those of ordinary skill in the art shall not depart from the essence and scope of the technical solution of the present invention.
