[0002] In the steel and coal industries, a large amount of bulk materials needs to be discharged by a belt conveying discharging trolley, and the discharging trolley is generally arranged on a track at the top of a stock bin. When the discharging trolley discharges materials, a large amount of dust is generated in the process of falling of the materials from a material conveying device to a discharging hopper and a chute. The discharging trolley is located at the top of the stock bin, and the dust diffuses throughout the stock bin, which affects the health of workers. Therefore, a mobile dust removal trolley is usually used in the discharging process.

[0003] The existing mobile dustproof trolley uses a steel plate and a sealing belt for sealing. Due to the wear and tear and loosening of the sealing belt and the accumulation of dust inside the sealing belt in the long-term use process, the sealing belt deviates from the track, the dust removal device is not tightly sealed, the pressure in the ventilation groove is reduced, and the dust removal effect is affected. In severe cases, the mobile dust removal trolley deviates from the running track. SUMMARY

The belt tightening rod drives the sealing belt to move downward in the belt fixing groove through friction. The arc surface of the locking slider is squeezed by the sealing belt and enters the locking slider groove, while the plane of the locking slider is squeezed on the sealing belt. At the same time, the sealing belt has a tendency to drive the belt tightening rod to rotate in the opposite direction, which increases the pressure of the locking slider plane on the sealing belt, prevents the sealing belt from loosening, and improves the sealing effect of the sealing belt.

[0019] 2. During the movement of the dust removal trolley, it is squeezed by the sealing belt and always moves in the roller travel groove. At the same time, the travel roller rolls in the roller travel groove, and the travel roller rolls on the sealing belt and compacts the sealing belt. The positioning rollers on both sides of the travel roller roll on the positioning track. The inclined groove design of the positioning track prevents the travel roller from deviating from the roller travel groove and the sealing belt from deviating from the belt sealing groove, while ensuring the sealing effect between the sealing belt and the dust removal trolley, and ensuring the negative pressure environment inside the dust removal trolley.

[0020] 3. When the sealing belt moves upward along the groove of the cleaning plate on the front side of the dust removal trolley, the roller is attached to the sealing belt, and the wedge slot of the roller is blocked by the straight edge of the limiting wedge, so that the roller cannot rotate and can only slide on the sealing belt, and at the same time drives the cleaning plate to rotate, so that the bottom of the cleaning plate is attached to the sealing belt to clean the dust on the surface, prevent excessive accumulation of dust on the surface of the sealing belt, and cause the sealing belt to detach from the belt sealing groove. When the sealing belt moves downward along the groove of the cleaning plate on the front side of the dust removal trolley, it will drive the roller to rotate again, and the bottom of the cleaning plate is away from the sealing belt, which prevents the cleaning plate and the roller from excessively wearing the sealing belt, thereby improving the service life of the sealing belt and the sealing performance.

[0032] Cleaning plate rotating shafts 311 are provided at both ends of the cleaning plate 31, spring grooves 3111 are provided on the cleaning plate rotating shaft 311, and support springs 3112 are provided on the spring grooves 3111. Roller grooves 312 are also provided at the tops of both ends of the cleaning plate 31, and slider grooves 313 are provided in the roller grooves 312. The roller assembly 33 is located in the roller grooves 312.

[0033] A limit plate slot 321 is provided on the edge of the belt limit plate 32, and the limit plate slot 321 is snapped onto the side plate of the limit plate groove 211.

[0034] The roller assembly 33 includes a roller 331, a roller fixing part 332 and a limiting wedge 333. The roller 331 rolls on the inner wall of the sealing belt 12. A baffle groove 3311 is provided on one side of the roller 331. A wedge slot 3312 is provided in a circular array on the edge of the baffle groove 3311. The roller fixing part 332 is provided with a slider 3321 and a roller shaft 3322. A baffle 3323 is provided at the end of the roller shaft 3322.

[0035] One end of the dust suction pipe 4 is a dust suction port 41, and the other end of the dust suction pipe 4 is a dust collection port 42. A tail fixing plate 43 is provided inside the dust collection port 42, and the tail fixing plate 43 is connected to the inspection plate 214 by bolts. The unloading vehicle 5 is provided with a unloading bin 51, and a dust suction groove 52 is provided on the top of the unloading bin 51. The dust suction port 41 is provided at the top of the dust suction groove 52 and is connected to the dust suction groove 52.

[0036] During specific use, when the unloading vehicle 5 is unloading, a large amount of dust will appear in the unloading bin 51. The ventilation slot body 11 generates suction under the action of the fan, and the airflow drives the dust in the unloading bin 51 through the dust suction slot 52 and the dust suction port 41 of the dust suction pipe 4, enters the dust suction pipe 4, and is discharged into the ventilation slot body 11 from the dust discharge port 42. The dust enters the ventilation slot body 11 and is then collected by the ventilation end of the ventilation slot body 11. The sealing belt 12 is set in the ventilation slot body. The end of the sealing belt 12 is fixed in the belt sealing groove 113 at the top of the body 11, and the end of the sealing belt 12 is fixed in the belt fixing groove 117. At the same time, the tightening rod regulating disk 14 is driven to rotate by rotating the crank 142 in the forward direction. The regulating disk gear 141 of the tightening rod regulating disk 14 drives the tightening rod gear 131, thereby rotating the belt tightening rod 13. The belt tightening rod 13 drives the end of the sealing belt 12 to move downward, thereby tightening the sealing belt 12. During the forward rotation of the belt tightening rod 13, the locking slider 133 is locked. When the belt 12 is tightened, the belt tightening rod 13 will no longer drive the sealing belt 12 to move, and the belt tightening rod 13 will only slide relatively on the sealing belt 12 to prevent the sealing belt 12 from loosening. At this time, after the locking slider 133 passes over the sealing belt 12, the crank handle 142 is stopped, and the plane of the locking slider 133 will fit on the sealing belt 12, and the sealing belt 12 cannot squeeze the locking slider 133 into the locking slider groove 132. At the same time, the sealing belt 12 has a tendency to drive the belt tightening rod 13 to rotate in the opposite direction, increasing the pressure of the plane of the locking slider 133 on the sealing belt 12, preventing the sealing belt 12 from loosening. When the sealing belt 12 is tightened, it will not deviate from the belt sealing groove 113, thereby improving the sealing effect of the dust removal ventilation slot 1.

[0037] During the movement of the unloading car 5, the dust collection pipe 4 is driven, and the dust collection pipe 4 drives the dust collection trolley 2 to move, so that the dust collection trolley 2 travels on the ventilation slot body 11, and the bottom of the dust collection trolley 2 slides between the two positioning rails 111. At the same time, during the movement of the dust collection trolley 2, the sealing belt 12 is fitted on the dust collection trolley 2 and moves. The dust collection trolley 2 is subjected to the pressure of the sealing belt 12, so that the dust collection trolley 2 is always fitted in the roller travel groove 112, and the travel roller 22 rolls in the roller travel groove 112, that is, the travel The roller 22 rolls on the sealing belt 12 and compacts the sealing belt 12. The positioning rollers 221 on both sides of the traveling roller 22 roll on the positioning track 111. The inclined groove design of the positioning track 111 prevents the traveling roller 22 from deviating from the roller traveling groove 112. The two pairs of belt limit plates 32 in front and behind the dust removal trolley 2 correct the sealing belt 12 to prevent the sealing belt 12 from deviating from the belt sealing groove 113, while ensuring the sealing effect between the sealing belt 12 and the dust removal trolley 2, and ensuring the negative pressure environment inside the dust removal trolley 2.

[0038] When the sealing belt 12 moves on the dust removal trolley 2, the sealing belt 12 moves upward from the front side of the dust removal trolley 2. When the sealing belt 12 moves upward along the cleaning plate groove 215, the roller 331 is attached to the sealing belt 12. Under the elastic force of the wedge spring 3331, the limiting wedge 333 slides into the wedge slot 3312 of the roller 331. The wedge slot 3312 is blocked by the straight edge of the limiting wedge 333, so that the roller 331 cannot rotate. The bottom of the cleaning plate 31 is moved upwardly in the slider slot 313 of the cleaning plate 31, so that the bottom of the cleaning plate 31 is in contact with the surface of the sealing belt 12, thereby cleaning the dust on the surface of the sealing belt 12 and preventing excessive accumulation of dust on the surface of the sealing belt 12. The sealing belt 12 is gradually lifted up in the belt sealing groove 113, causing the dust removal ventilation slot 1 to leak, thereby reducing the airtightness and negative pressure strength of the dust removal ventilation slot 1. The belt cleaning device 3 is also provided at the rear side of the dust removal trolley 2 to ensure that the sealing belt 12 can be cleaned at the same time during the two-way movement of the dust removal trolley 2. When the sealing belt 12 passes the rear side of the dust removal trolley 2, the sealing belt 12 moves downwardly. When the roller 331 rolls on the sealing belt 12, the wedge slot 3312 will squeeze the oblique edge of the limiting wedge 333, and then squeeze the limiting wedge 333 into the wedge slot 3324, so as not to block the rotation of the roller 331. At the same time, the roller 331 and the sealing belt 12 move downward, driving the cleaning plate 31 to rotate, so that the bottom of the cleaning plate 31 is away from the sealing belt 12, preventing the cleaning plate 31 and the roller 331 from excessively wearing the sealing belt 12, thereby increasing the service life of the sealing belt 12.
