The fixing frame 12 is arranged in the middle of the two groups of base bodies 11, so that the end output end of the motor body 1 will drive the belt 15 to rotate, and at the same time will drive the first rotating shaft 14 to move synchronously. Because the end of the first rotating shaft 14 is hingedly connected to the second rotating shaft 16, the rotation of the second rotating shaft 16 can drive the plurality of fan blades 17 arranged in the middle to move. At this time, the fan blades 17 can blow upward during rotation, and the surface of the base body 11 can be cooled and dusted. This step can accelerate the flow of air in the working environment of the motor body 1, reduce the problem that the surface temperature of the motor body 1 is too high and difficult to dissipate after long-time high-load work, and cause internal circuit damage of the motor body 1. At the same time, with the help of upward blowing wind power, the problem of surface accumulation of more coal dust can be reduced when the motor body 1 works in a coal environment for a long time, and the cleanliness of the middle of the motor body 1 is improved.

[0024] As Figure 2 And 3As shown, the fixed frame 12 bottom torsion spring is connected with the frame 2; the frame 2 middle part is fixedly connected with the filter screen 21; the frame 2 top is fixedly connected with the first top block 22; the first rotating shaft 14 middle part is fixedly connected with the second top block 23; the second top block 23 and the first top block 22 middle part are arc-shaped; during operation, by setting the frame 2 in the middle of the fixed frame 12, the frame 2 end will be attached to the inner wall of the fixed frame 12 bottom during the non-rotation of the first rotating shaft 14, and when the first rotating shaft 14 rotates, the air-permeable filter screen 21 will block the dust from the outside, and at the same time, the second top block 23 set in the middle will move synchronously during the rotation of the first rotating shaft 14, and when the second top block 23 is close to the middle part of the first top block 22, because they are arc-shaped, the second top block 23 can push the frame 2 downward, at this time the frame 2 will be inclined in the fixed frame 12 bottom, and then after the reset of the torsion spring, it will quickly impact on the fixed frame 12 bottom, and this step is repeated, and the filter screen 21 is set to reduce the problem that the impurities or garbage from the outside adhere to the fan blade 17 and the middle part of the second rotating shaft 16 under the action of suction force during the rotation of the fan blade 17, and after a long time, the first rotating shaft 14 and the second rotating shaft 16 connection appears large resistance, and the second top block 23 can make the frame 2 frequently rotate in the fixed frame 12 bottom, and improve the cycle of the filter screen 21 during use.

[0025] As shown in Figure 2 and 4 The motor body 1 end is fixedly connected with the support plate 3; the support plate 3 top is rotatably connected with the rotating plate 31; the rotating plate 31 end is fixedly connected with a plurality of scraping blades 32; the scraping blade 32 end and the middle part of the belt 15 are in contact; during operation, by setting the support plate 3 at the end of the motor body 1, the plurality of scraping blades 32 will be closely attached to the middle part of the belt 15 and remove the impurities attached to the surface of the belt 15 under the friction and the gravity of the overall downward pressure of the rotating plate 31 during the clockwise movement of the belt 15, and the rotating plate 31 is set to improve the cleanliness of the middle part of the belt 15, reduce the problem that the belt 15 surface accumulates a lot of coal dust or impurities, causes subsequent caking and corrosion of the belt 15 surface, and improves the use cycle of the belt 15.

[0026] As shown in Figure 4As shown, the bottom of the support plate 3 is fixedly connected with a fixing part 4; the inner wall of the fixing part 4 is fixedly connected with a first spring 41; the top of the first spring 41 is fixedly connected with a top ball 42; the top of the top ball 42 is in contact with the middle part of the rotating plate 31; in working, the first spring 41 is arranged at the bottom of the support plate 3, so that when the belt 15 rotates clockwise, the middle part of the top ball 42 is pressed, and at the same time, the length of the first spring 41 is compressed, and when the output end of the motor body 1 reversely rotates, the elastic force generated by the first spring 41 and the friction force generated after the scraper 32 is removed can make the rotating plate 31 frequently shake up and down in the middle part of the support plate 3, and the shaking force generated by the first spring 41 arranged in this step can clean the impurities accumulated and caked in the middle part of the scraper 32, and improve the accuracy of the subsequent scraping of the middle part of the belt 15 by the scraper 32.

[0027] As shown in Figure 4 , the end of the rotating plate 31 is fixedly connected with a second spring 5; the end of the second spring 5 is fixedly connected with a counterweight 51; in working, the second spring 5 is arranged at the output end of the rotating plate 31, and under the action of inertia, the counterweight 51 shakes at the output end of the rotating plate 31, and this step cooperates with the shaking counterweight 51 and the easily deformable second spring 5 to improve the frequency of the whole rotating plate 31 shaking in the middle part of the support plate 3, and further reduces the problem that the scraper 32 needs to be frequently manually cleaned.

[0028] As shown in Figure 4 , the middle part of the scraper 32 is fixedly connected with a reinforcing part 6, and the other end of the reinforcing part 6 is fixedly connected to the top of the rotating plate 31; in working, the reinforcing part 6 is arranged in the middle part of the plurality of scrapers 32, so that the reinforcing part 6 fixes the ends of the plurality of scrapers 32 together, and this step cooperates with the reinforcing part 6 to improve the problem of deformation and bending of the middle part of the scraper 32 after long-term use, and further improves the accuracy of the scraper 32 in scraping the impurities in the middle part of the belt 15.

[0029] As shown in Figure 4 , the middle part of the top ball 42 is fixedly connected with a rubber pad 7; in working, the rubber pad 7 is arranged in the middle part of the top ball 42, so that the rotating plate 31 contacts the surface of the rubber pad 7 first during extruding the top ball 42, and this step cooperates with the rubber pad 7 to reduce the wear and tear and scratches between the middle part of the rotating plate 31 and the top ball 42, and reduces the problem that the two are difficult to push the top ball 42 downward after subsequent contact.

[0030] The working principle is that the two groups of base bodies 11 are fixed in the working area by bolts, and the motor body 1 is connected to the power supply to normally work. The fixed frame 12 is arranged in the middle of the two groups of base bodies 11, so that the end output of the motor body 1 drives the belt 15 to rotate during the working process, and simultaneously drives the first rotating shaft 14 to move synchronously. The first rotating shaft 14 is hingedly arranged between the end and the second rotating shaft 16, and the rotating force of the second rotating shaft 16 drives the plurality of fan blades 17 arranged in the middle to move. At this time, the fan blades 17 can blow upward during the rotating process, and the surface of the base body 11 is cooled and dusted. The frame 2 is arranged in the middle of the fixed frame 12, so that the end of the frame 2 is attached to the inner wall at the bottom of the fixed frame 12 when the first rotating shaft 14 is not rotating. When the first rotating shaft 14 rotates, the air-permeable filter screen 21 can block the dust from the outside. When the first rotating shaft 14 rotates, the second top block 23 arranged in the middle moves synchronously, and when the second top block 23 is close to the middle of the first top block 22, the second top block 23 can drive the frame 2 as a whole to be downwardly jolted due to the arc-shaped arrangement between the two. At this time, the frame 2 is inclined at the bottom of the fixed frame 12, and then is quickly impacted on the bottom of the fixed frame 12 after being reset by the torsional spring, so as to be repeatedly performed. The support plate 3 is arranged at the end of the motor body 1, so that the plurality of scrapers 32 are closely attached to the middle of the belt 15 and remove the impurities attached to the surface of the belt 15 under the friction force and the gravity of the whole downward pressing of the rotating plate 31 when the belt 15 rotates clockwise. The first spring 41 is arranged at the bottom of the support plate 3, so that the middle of the pressure ball 42 is pressed when the belt 15 rotates clockwise, and the length of the first spring 41 is compressed. When the output end of the motor body 1 reversely rotates, the friction force generated after the first spring 41 and the scraper 32 are separated can make the rotating plate 31 frequently shake up and down in the middle of the support plate 3. The second spring 5 is arranged at the rotating output end of the rotating plate 31, and under the action of inertia, the counterweight 51 is shaken at the output end of the rotating plate 31. The reinforcing member 6 is arranged in the middle of the plurality of scrapers 32, so that the reinforcing member 6 fixes the ends of the plurality of scrapers 32 together. The rubber pad 7 is arranged in the middle of the pressure ball 42, so that the rotating plate 31 contacts the surface of the rubber pad 7 first during the extrusion of the pressure ball 42.
