[0034] The working principle of the coal cleaning device of the belt 2 conveyor 1 is as follows:

[0035] Reciprocal cleaning:

[0036] When the belt 2 conveyor 1 is started, the driving motor 21 starts to work, the output end of the driving motor 21 drives the reciprocating screw rod 22 to rotate, the reciprocating screw rod 22 drives the rotating shaft 3 to rotate, the belt roller 4 fixedly connected with the rotating shaft 3 drives the belt 2 to convey coal, the reciprocating screw rod 22 is threadedly connected with the sliding sleeve 23, the reciprocating screw rod 22 rotates to drive the sliding sleeve 23 to make reciprocating linear motion along the reciprocating screw rod 22, the driving sliding plate 24 fixedly connected with the outer wall of the sliding sleeve 23 moves together with the sliding sleeve 23, the driving sliding plate 24 is connected with the driven sliding plate 25 through the slide rod 26, and therefore the slide rod 26 drives the reciprocating scraper 7 to make reciprocating motion on one side of the conveyor 1, at this moment, in the process that the belt 2 continuously moves, the reciprocating scraper 7 first contacts the surface of the belt 2, the reciprocating scraper 7 makes reciprocating motion and has a length greater than that of the belt 2, so that the reciprocating scraper 7 can clean different positions of the belt 2 in the transverse direction and effectively cover the whole width direction of the belt 2, and the coal on the surface of the belt 2 is preliminarily cleaned and most of the coal, which is relatively loose and located at the edge of the belt 2, is scraped off.

[0037] Secondary cleaning:

[0038] Meanwhile, the fixed scraper 6 is installed on the top of the fixed seat 5, and the angle and pressure of the fixed scraper 6 can be adjusted through the adjusting assembly, when adjusting, the rotating adjusting nut 35 is rotated, the adjusting nut 35 moves on the thread of the adjusting rod 32, the adjusting nut 35 exerts pressure on the gasket 34 to change the pressure of the gasket 34 on the spring 33, the spring 33 exerts pressure on the other gasket 34, the gasket 34 slides on the adjusting rod 32 to drive the adjusting plate 36 to rotate, since the bottom of the adjusting plate 36 is fixedly connected with the fixed seat 5, the fixed scraper 6 on the fixed seat 5 also rotates to realize the adjustment of the contact angle and pressure of the fixed scraper 6 and the belt 2, so that the fixed scraper 6 can better fit the surface of the belt 2, when the adjusting plate 36 rotates, the adjusting rod 32 also rotates on the fixed plate 31, so that the adjusting rod 32 always forms a 90-degree angle with the adjusting plate 36, when the belt 2 continuously moves forward after being preliminarily cleaned by the reciprocating scraper 7, the fixed scraper 6 cleans the belt 2 again to further remove the residual and stubbornly attached coal on the belt 2, and ensure that the coal on the surface of the belt 2 is cleaned as much as possible.

[0039] Disassembling and assembling the fixed scraper 6:

[0040] When the fixed scraper 6 needs to be replaced or repaired, only the bolt 43 and the fixed nut 44 at one end of the fixed seat 5 are unscrewed, and the inserted piece 42 at the bottom of the fixed scraper 6 is pulled out of the L-shaped sliding groove 41, when assembling, the inserted piece 42 is inserted into the L-shaped sliding groove 41, and then the bolt 43 and the fixed nut 44 are used for fixing.

[0041] The above only describes the embodiments of the present application, and does not limit the patent range of the present application, any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, is also included in the patent protection range of the present application.
