Description

Technical Field

[0001] The utility model relates to the technical field of coal crushers, in particular to a coal crusher. Background Art

[0002] After searching, Chinese Patent No. 202221949877.1 discloses a coal crusher. The utility model rotates a screening element arranged in a shell, and the screening element has a screening groove. Coal particles enter the feed trough from the discharge hopper and are screened by the screening element. Coal particles with smaller particle sizes fall directly into the first discharge channel through the screening groove, and coal particles with larger particle sizes fall into the first discharge channel from both ends of the screening element. Coal particles of different particle sizes are pre-screened before crushing, so that coal with smaller particle size does not need to be crushed, thereby improving the crushing efficiency.

[0003] Under the existing technology, in the field of mining electromechanics, workers often use coal crushers to crush whole pieces of coal to facilitate the later use and transportation of the coal. However, some existing coal crushers can only crush coal blocks and directly pile the crushed coal blocks on the ground. The structure is relatively simple and it is not easy to collect the crushed coal blocks. The workers need to collect the coal blocks piled on the ground, which is time-consuming and labor-intensive, increases the labor intensity of the workers, and indirectly affects the work efficiency of the workers.

The two sets of transmission rollers 12 are connected through a conveyor belt 13. The conveyor belt 13 can convey the crushed coal blocks. The outer side of the conveyor belt 13 is fixedly connected with a baffle 14. Through the setting of the baffle 14, the crushed coal blocks can be firmly blocked on the conveyor belt 13, which effectively prevents the conveyor from being crushed. When the belt 13 drives the broken coal blocks to move, the broken coal blocks may fall off. The baffle can prevent the coal blocks from sliding off the surface of the conveyor belt 13. A third transmission wheel 15 is fixedly sleeved on the front side of the outer surface of the left transmission roller 12. The second transmission wheel 8 is connected to the third transmission wheel 15 through a second belt 16. A collecting trough 17 is provided on the inner side of the fixed plate 11.

Due to the rotatability of the moving wheel 18, it is convenient for the staff to move the collecting trough 17.

[0024] In order to ensure the stability of the rotating shaft 6 when it rotates along the inside of the shell 2, the utility model has a stabilizing plate 19 movably sleeved on the front side of the outer surface of the rotating shaft 6. Through the mutual cooperation between the stabilizing plate 19 and the supporting plate 20, the rotating shaft 6 in rotation can be effectively limited and supported to prevent the rotating shaft 6 from shaking significantly during rotation, thereby ensuring the stability of the rotating shaft 6 in rotation along the inside of the shell 2. The lower surface of the stabilizing plate 19 is fixedly connected to the supporting plate 20, and the back side of the supporting plate 20 is fixedly connected to the front side of the shell 2. The mutual cooperation between the stabilizing plate 19 and the supporting plate 20 can effectively limit and support the rotating shaft 6 in rotation, thereby ensuring the stability of the rotating shaft 6 in rotation along the inside of the shell 2.

[0025] In order to improve the stability of the connection between the feed trough 5 and the shell 2, the utility model has a reinforcement plate fixedly connected to the right side of the lower surface of the feed trough 5, and the right side of the reinforcement plate is fixedly connected to the top of the left side of the shell 2. The reinforcement plate increases the connection area between the feed trough 5 and the shell 2, and improves the stability of the connection between the feed trough 5 and the shell 2.

[0026] In order to ensure the stability of the left-side transmission roller 12 during rotation, the utility model has a stabilizing block 22 movably sleeved on the front side of the outer surface of the left-side transmission roller 12. The stabilizing block 22 can limit and support the rotating transmission roller 12 on the left side, thereby indirectly ensuring the stability of the left-side transmission roller 12 during rotation.

[0028] In order to improve the stability of the connection between the support plate 20 and the shell 2, the utility model has a triangular plate 21 fixedly connected to the lower surface of the support plate 20. Through the arrangement of the triangular plate, the connection area between the feed trough 5 and the shell 2 is increased, and the stability of the feed trough 5 when being used is indirectly guaranteed. The back side of the triangular plate 21 is fixedly connected to the front side of the shell 2.

[0030] When in use, the staff starts the drive motor 3, and the output end of the drive motor 3 drives the first transmission wheel 4 to rotate clockwise. At the same time, due to the setting of the first belt 10, the first transmission wheel 4 can indirectly drive the second transmission wheel 8 to rotate clockwise, and then the second transmission wheel 8 drives the rotating shaft 6 to rotate clockwise along the stabilizing plate 19 and the inside of the shell 2, and the rotating shaft 6 drives the crushing roller 7 to rotate clockwise inside the shell 2. Then the staff pours the whole piece of coal into the inside of the shell 2 through the feed chute 5. When the crushing roller 7 contacts the coal, it can start to crush it. Then the crushed coal falls into the inside of the inclined plate 9. Because the inclined plate 9 is in an inclined state, the crushed coal will roll to the right along the inside of the inclined plate 9 until it rolls onto the conveyor belt 13. At the same time, due to the setting of the second belt 16, the second transmission The wheel 8 can indirectly drive the third transmission wheel 15 to rotate clockwise, and the third transmission wheel 15 drives the transmission roller 12 on the left to rotate clockwise along the inside of the fixed plate 11. At the same time, due to the setting of the conveyor belt 13, the conveyor belt 13 and the transmission roller 12 on the right can be driven to rotate at the same time, so that the conveyor belt 13 drives the baffle 14 to rotate. Because the baffle 14 blocks the coal blocks, the coal blocks can be prevented from rolling on the surface of the conveyor belt 13 until the conveyor belt 13 and the baffle 14 transport the crushed coal blocks to the designated position, and finally fall into the collecting tank 17. After the collection is completed, due to the rotatability of the moving wheel 18, the staff can pull the collecting tank 17 out of the inner side of the fixed plate 11, and then push the collecting tank 17 filled with crushed coal blocks to the designated storage point. At this point, the crushing, collection and transportation of the coal blocks are completed.
