[0024] refer to Figures 1 to 6 A floating coal cleaning device for a tail roller of a mining belt conveyor, comprising a rectangular frame 2 mounted on a body frame at the tail of the belt conveyor, the rectangular frame 2 being arranged in parallel with the tail roller 1 of the belt conveyor, a scraper 3 is arranged close to the side of the tail roller 1 of the belt conveyor along its axial direction, the scraper 3 is arranged on the rectangular frame 2, and the scraper 3 is used to scrape the floating coal particles on the tail roller 1 of the belt conveyor to avoid the belt from running off and reduce the damage rate of the belt;

[0025] A collecting port is provided on the top wall of the rectangular frame 2, a cavity is provided in the rectangular frame 2 in a horizontal direction, the collecting port is connected to the cavity, rotating rollers 6 are vertically installed at both ends of the cavity, a same conveyor belt 5 is sleeved on the two rotating rollers 6, the rotating rollers 6 rotate to drive the conveyor belt 5 to move, the conveyor belt 5 is used to take out the cleaned floating coal, instead of manually cleaning the floating coal under the scraper, which reduces the labor intensity of the staff, and also avoids the potential safety hazard of manual cleaning to the personal safety of the staff;

[0026] A rotating shaft 11 of one of the rotating rollers 6 extends out of the rectangular frame 2, and a first bevel gear 12 is sleeved on the protruding end. A second bevel gear 13 meshing with the first bevel gear 12 is provided on one side of the first bevel gear 12. The second bevel gear 13 is sleeved on the central axis of the tail roller 1 of the belt conveyor. The tail roller 1 of the belt conveyor rotates to drive the first bevel gear 12 to rotate through the second bevel gear 13 sleeved on its central axis, thereby driving one of the rotating rollers 6 to rotate through the rotating shaft 11, and then driving the conveyor belt 5 to move, so as to bring out the floating coal under the scraper.

[0027] The floating coal on the surface of the tail roller 1 of the belt conveyor is scraped off by the scraper 3, and the scraped floating coal is discharged to both sides of the belt conveyor through the rotating roller 6 and the conveyor belt 5, thereby avoiding manual cleaning of the scraped floating coal, reducing the labor intensity of the staff, and avoiding safety hazards to the personal safety of the staff caused by manual cleaning.

[0028] A strip-shaped mounting block 8 is installed at the bottom of the scraper 3 along its length direction. A support rod 9 is horizontally penetrated through the strip-shaped mounting block 8. Both ends of the support rod 9 are arranged on the rectangular frame 2 through fixing blocks 7.

[0029] The lower end of the scraper 3 is connected with an arc-shaped guide plate 4, which is used to guide the cleaned floating coal into the collection port and bring it out through the conveyor belt 5.

[0030] Water nozzles 10 are installed on both sides of the scraper 3 through vertical connecting pipes 14. The water nozzles 10 are facing the tail roller 1 of the belt conveyor. The water nozzles 10 are used to flush the coal powder particles on the surface of the tail roller 1 of the belt conveyor and make them flow into the rectangular frame 2 to prevent the coal powder from being adsorbed on the surface of the tail roller 1 of the belt conveyor, thereby causing the belt to deviate.

[0031] A gap is left between the conveyor belt 5 and the inner wall of the rectangular frame 2, and the gap is used to prevent the rectangular frame 2 from blocking the floating coal under the scraper, thereby affecting the conveyor belt 5 from conveying the floating coal under the scraper.

[0032] The device also includes a coal-rolling prevention device 15 disposed at the bottom of the rectangular frame 2, and the coal-rolling prevention device 15 is used to prevent floating coal from being drawn into the belt and the tail roller 1 of the belt conveyor, thereby preventing the floating coal from jamming the tail roller 1 of the belt conveyor;

[0033] The anti-coal rolling device 15 includes an arc-shaped guide groove 1502 arranged at the bottom of the rectangular frame 2 through a vertical plate 1504. The arc-shaped guide groove 1502 is vertically arranged on the inner wall of the belt and is slidably connected to the belt. The belt is propped up by the cooperation of the vertical plate 1504 and the arc-shaped guide groove 1502, so that the belt has a slope. The vertical plate 1504 is arranged on one side of the arc-shaped guide groove 1502, and a shovel plate 1503 inclined upward is arranged on the other side of the arc-shaped guide groove 1502. The belt has a slope. When the floating coal falls on the inner wall of the belt, it moves downward under the influence of gravity. The shovel plate 1503 slides into the arc guide groove 1502 to prevent floating coal from clogging the tail roller 1 of the belt conveyor. A spiral rod 1506 is provided in the arc guide groove 1502 along the tangential direction. A sealing plate 1501 is provided at one end of the arc guide groove 1502. One end of the spiral rod 1506 extends out of the sealing plate 1501 and is connected to an external driving mechanism. The rotation of the spiral rod 1506 drives the floating coal inside the arc guide groove 1502 to move outward, and the floating coal that falls on the inside of the belt is cleaned to prevent the tail roller 1 of the belt conveyor from being stuck with the belt, thereby causing the belt to break.

[0034] The external driving mechanism is a driving motor 1505 .

[0035] The working principle of the present invention is as follows: the driving motor 1505 is started, the flushing nozzle 10 is connected to the external water pipe, and the flushing nozzle 10 is controlled to spray water, so that the flushing nozzle 10 flushes the surface of the tail roller 1 of the belt conveyor, and the coal powder adsorbed on the surface of the tail roller 1 of the belt conveyor is washed down, and flows into the cavity through the scraper 3 and the arc guide plate 4, and finally discharged to both sides of the belt conveyor;

[0036] When the belt conveyor is started, the tail roller 1 of the belt conveyor is driven to rotate synchronously. When the tail roller 1 of the belt conveyor rotates, the scraper 3 scrapes the floating coal on the tail roller 1 of the belt conveyor and enters the conveyor belt 5 in the rectangular frame 2 through the arc guide plate 4;

[0037] At the same time, the tail roller 1 of the belt conveyor rotates to drive the first bevel gear 12 to rotate through the second bevel gear 13 on its central axis, and drives the rotating roller 6 to rotate through the rotating shaft 11, thereby driving the conveyor belt 5 to move, and transporting the floating coal on the conveyor belt 5 to both sides of the belt conveyor.

[0038] When the floating coal falls on the inner side of the belt, it moves downward due to gravity and slides into the arc guide groove 1502 through the shovel plate 1503. The drive motor 1505 starts to drive the screw rod 1506 to rotate. The rotation of the screw rod 1506 drives the floating coal inside the arc guide groove 1502 to move outward, and the floating coal that falls on the inner side of the belt is carried out.

[0039] The present invention scrapes the floating coal on the surface of the tail roller 1 of the belt conveyor through the scraper 3, and discharges the scraped floating coal to both sides of the belt conveyor through the rotating roller 6 and the conveyor belt 5, thereby avoiding manual cleaning of the scraped floating coal, reducing the labor intensity of the staff, and avoiding the safety hazard of manual cleaning to the personal safety of the staff.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
