[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1-4 , this utility model provides two technical solutions:

[0021] Example 1

[0022] See also Figure 1 In an embodiment of the utility model, a thermal power generation coal crusher with dust removal and vibration reduction includes a base 1, a shock-absorbing pad 2 is provided on the upper part of the base 1, a crushed coal box 3 is provided on the upper part of the shock-absorbing pad 2, a feed port 4 is provided on the upper part of the crushed coal box 3, and a dust-proof mechanism 5 is provided between one side of the crushed coal box 3 and the feed port 4. The thermal power generation coal crusher with dust removal and vibration reduction also includes a driving mechanism 6 for driving the crusher inside the crushed coal box 3 to rotate.

[0023] See also Figure 2 In the embodiment of the present invention, the dust-proof mechanism 5 includes a storage box 51 arranged on one side of the crushed coal box 3 and a cover plate 52 hinged to the edge of the side of the feed port 4 away from the crushed coal box 3. The side of the cover plate 52 away from the feed port 4 is provided with a side panel 53, one side of the side panel 53 is provided with an opening groove 54, and the other side of the side panel 53 is provided with a dust hood 55 communicating with the opening groove 54. A suction fan 56 is installed on the side of the dust hood 55 away from the side panel 53, and the outlet end of the suction fan 56 is connected to a conveying pipe 57, and the other end of the conveying pipe 57 is provided in the storage box 51.

[0024] In the above scheme, coal is poured into the feed port 4 and the suction fan 56 is operated, so that dust generated by the coal pouring is sucked into the suction fan 56 and falls into the storage box 51 for storage.

[0025] For further information, see Figure 2 In the embodiment of the present invention, a hydraulic cylinder 58 is installed on the side of the storage box 51 away from the crushed coal box 3. The output shaft of the hydraulic cylinder 58 is hinged with a connecting rod 59. One end of the connecting rod 59 away from the output shaft of the hydraulic cylinder 58 is hinged to the side of the cover plate 52. The hydraulic cylinder 58 drives the connecting rod 59 to move, and the connecting rod 59 rotates the cover plate 52 so that the cover plate 52 covers the feed port 4. In this way, no dust will be generated during crushing.

[0026] For further information, see Figure 2In the embodiment of the present invention, air-permeable nets 510 are provided on the upper sides of both sides of the storage box 51. The air-permeable nets 510 can enable the suction fan 56 to smoothly suck the dust into the storage box 51, thereby preventing the internal pressure of the storage box 51 from being too high.

[0027] The second embodiment differs from the first embodiment in that:

[0028] See also Figure 3-Figure 4 In the embodiment of the present invention, the driving mechanism 6 includes a driving motor 61 arranged on the upper part of the base 1 and a driven wheel 62 rotatably arranged on one side of the coal crushing box 3. One end of the driven wheel 62 is connected to the crusher inside the coal crushing box 3. The output shaft of the driving motor 61 is connected to the driving wheel 63. The driving wheel 63 and the driven wheel 62 are connected by a belt 64. The driving mechanism 6 also includes a belt tensioning assembly 65 for tensioning the belt 64.

[0029] In the above scheme, during crushing, the driving motor 61 drives the driving wheel 63 to rotate, the driving wheel 63 causes the belt 64 to drive the driven wheel 62 to rotate, and the driven wheel 62 drives the crusher inside the coal crushing box 3 to rotate, and the crusher crushes the coal.

[0030] See also Figure 3-Figure 4 In the embodiment of the present invention, the belt tensioning assembly 65 includes a screw 651 rotatably arranged on the upper part of the base 1, and the outside of the screw 651 is screwed with a moving block 652 through a thread, and a handle 653 is also provided on the outside of the screw 651. A guide roller 654 is rotatably provided at one end of the moving block 652, and the guide roller 654 is used to adjust the tension of the belt 64.

[0031] In the above scheme: if the belt 64 is too loose, the screw 651 is driven to rotate by rotating the handle 653, the screw 651 drives the moving block 652 to move, and the moving block 652 drives the guide roller 654 to move, so that the guide roller 654 presses the belt 64 downward, so that the belt 64 is in a taut state to prevent the belt 64 from slipping.

[0032] For further information, see Figure 3-Figure 4 In the embodiment of the present invention, the upper part of the moving block 652 is located on one side of the screw 651 and a limit rod 655 is longitudinally slidably provided. The lower end of the limit rod 655 is fixedly provided on the upper part of the base 1. When the moving block 652 moves, it will slide on the limit rod 655, which plays a guiding and limiting role for the moving block 652.

[0033] Working principle: Pour coal into the feed port 4, then the hydraulic cylinder 58 drives the connecting rod 59 to move, and the connecting rod 59 rotates the cover plate 52 so that the cover plate 52 covers the feed port 4. In this way, no dust will be generated during crushing. When pouring coal, the cover plate 52 opens the feed port 4 and the suction fan 56 is operated at the same time. In this way, the dust generated by pouring coal will be sucked into the suction fan 56 and fall into the storage box 51 for storage.

[0034] During crushing, the driving motor 61 drives the active wheel 63 to rotate, and the active wheel 63 causes the belt 64 to drive the driven wheel 62 to rotate, and the driven wheel 62 drives the crusher inside the coal crushing box 3 to rotate, and the crusher crushes the coal. If the belt 64 is too loose, the screw 651 is driven to rotate by turning the handle 653, and the screw 651 drives the moving block 652 to move, and the moving block 652 drives the guide roller 654 to move, so that the guide roller 654 presses the belt 64 downward, so that the belt 64 is in a taut state to prevent the belt 64 from slipping.
