[0024] EMBODIMENT

[0025] Referring to Figs. 1-3 As shown in the figure, the present embodiment provides a dust cover of a belt conveyor, which comprises an upper cover body 1 and a lower cover body 2. The upper cover body 1 and the lower cover body 2 achieve full wrapping of the conveying section, effectively avoiding the outward diffusion of dust. The upper cover body 1 and the lower cover body 2 are respectively fixed at the top and the bottom of the belt conveyor 3. Specifically, the upper cover body 1 and the lower cover body 2 can be respectively fixed at the top and the bottom of the rack of the belt conveyor 3 by bolts. The top plate of the upper cover body 1 is connected with the spraying frame 5 through the lifting driving assembly 4. The spraying frame 5 is provided with uniformly distributed nozzles 6. The lifting driving assembly 4 can drive the spraying frame 5 and the nozzles 6 to move up and down. The top plate of the upper cover body 1 is provided with through holes 7 corresponding to the nozzles 6. After the lifting driving assembly 4 drives the nozzles 6 to descend, the nozzles 6 can pass through the through holes 7 to enter the inside of the upper cover body 1 to facilitate spraying and dust removal. After the lifting driving assembly 4 drives the nozzles 6 to ascend, the nozzles 6 can move out of the upper cover body 1 to facilitate maintenance. The side plate of the upper cover body 1 is provided with access doors 8 which are uniformly distributed along the conveying direction of the belt conveyor 3. The access doors 8 facilitate the maintenance of the components of the belt conveyor 3 in the upper cover body 1. The two ends of the upper cover body 1 are respectively provided with a feeding port and a discharging port. The feeding port and the discharging port are both provided with dust curtains 9. The dust curtains 9 can block the dust, thereby preventing the dust from diffusing into the air outside the dust cover.

[0026] In use, the conveying belt 13 on the belt conveyor 3 conveys the materials, and the lower cover body 2 can collect the conveying material residues falling from the conveying belt 13. The upper cover body 1 and the lower cover body 2 can realize full wrapping of the conveying section, effectively avoiding the diffusion of dust outward. Meanwhile, the dustproof curtain 9 and the nozzle 6 can further prevent the diffusion of dust outward of the dustproof cover. When the components of the belt conveyor 3 need to be overhauled, the maintenance door 8 can be opened for maintenance. When the nozzle 6 needs to be overhauled, the nozzle 6 can be driven by the lifting driving assembly 4 to move out of the upper cover body 1.

[0027] In a further preferred embodiment, the outer wall of the nozzle 6 is fixedly connected with a sealing sleeve matched with the structure of the through hole 7. The sealing sleeve can increase the sealing performance between the nozzle 6 and the through hole 7, preventing dust from overflowing from the gap between the nozzle 6 and the through hole 7.

[0028] In a further preferred embodiment, the lifting driving assembly 4 includes a plurality of support seats 41 and lifting driving devices 42 arranged alternately. The support seats 41 and the lifting driving devices 42 are fixedly connected with the top plate of the upper cover body 1. The top end of the support seat 41 and the top end of the telescopic part of the lifting driving device 42 are provided with bearing grooves 43 matched with the structure of the spraying frame 5. The height of the bearing groove 43 on the lifting driving device 42 is lower than that of the bearing groove 43 on the support seat 41 when the telescopic part is fully retracted, and the height of the bearing groove 43 on the lifting driving device 42 is higher than that of the bearing groove 43 on the support seat 41 when the telescopic part is fully extended. The lifting driving device 42 can be a hydraulic cylinder connected with an oil cylinder by a hydraulic pump to provide hydraulic power.

[0029] When maintenance is needed, the lifting driving device 42 drives the spraying frame 5 to rise. At this time, the lifting driving device 42 supports the spraying frame 5. During normal operation, the lifting driving device 42 drives the spraying frame 5 to descend, and the spraying frame 5 falls onto the bearing groove 43 of the support seat 41, which supports the spraying frame 5. The support seat 41 can reduce the pressure time of the lifting driving device 42, thereby prolonging the service life of the lifting driving device 42.

[0030] In a further preferred embodiment, the dustproof curtain 9 includes a plurality of adjacent rubber strips. The top end of each rubber strip is fixedly connected with the top plate of the upper cover body 1. The rubber strips facilitate the entry and exit of materials.

[0031] Further preferably, the lower cover body 2 is provided with a scraper 10, the bottom end of the scraper 10 is slidably connected with the bottom plate of the lower cover body 2, one end of the scraper 10 passes through a long strip-shaped through hole 11 on the side plate of the lower cover body 2 and is connected with a horizontal driving assembly 12, the length direction of the long strip-shaped through hole 11 is parallel to the conveying direction of the belt conveyor 3.

[0032] Further preferably, the horizontal driving assembly 12 comprises a support plate 121, the support plate 121 is fixedly connected with the side plate of the lower cover body 2. The support plate 121 is provided with a rack 122 arranged along the conveying direction of the belt conveyor 3, and the support plate 121 is further slidably connected with a sliding seat 123. The sliding seat 123 is fixedly connected with a motor 124, the output shaft of the motor 124 is fixedly connected with a gear shaft 125, the teeth on the gear shaft 125 are in meshing connection with the rack 122. The other end of the gear shaft 125 is rotatably connected with a insertion hole on a limiting block 126, the limiting block 126 is slidably arranged in the long strip-shaped through hole 11 and is fixedly connected with the scraper 10.

[0033] In use, the motor 124 drives the gear shaft 125 to rotate, because the teeth on the gear shaft 125 are in meshing connection with the rack 122, so that the motor 124, the sliding seat 123 and the gear shaft 125 can move integrally along the direction of the rack 122, the movement of the gear shaft 125 enables the limiting block 126 to slide in the long strip-shaped through hole 11, the movement of the limiting block 126 drives the scraper 10 to move, thereby achieving the scraping effect on the slag in the lower cover body 2.

[0034] Therefore, the belt conveyor dust cover with the above structure has good dust prevention effect and facilitates the maintenance of the components in the dust cover.
