Detailed Description

The technical solutions in the embodiments of the present invention are described below clearly and completely, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in figure 1, the vertical shaft bottom coal scattering cleaning device comprises a hoisting machine 2 arranged in a vertical shaft 1, wherein the hoisting machine 2 is fixed on a shaft wall 101. The bottom of the vertical shaft 1 is provided with an inclined chute 3 and a drainage slope 4, and the coal automatically slides to a feeding port 5 of the elevator 2 under the action of gravity after falling on the inclined chute 3 at the bottom of the shaft; seepage water on the left and right side well walls 101 also flows to a feeding port 5 of the elevator 2 through a drainage slope 4 and an inclined chute 3 respectively. One end of the coal guide groove 7 is hinged with the discharge port 6 of the elevator 2, the coal guide groove 7 is connected with the elevator 2 through a telescopic cylinder 8, and two ends of the telescopic cylinder 8 are respectively hinged with the coal guide groove 7 and the shell of the elevator 2. The angle of the coal guide groove 7 can be changed by the extension and contraction of the telescopic cylinder 8. The telescopic cylinder 8 can adopt an air cylinder or an oil cylinder, and can also adopt an electric push rod.

During operation, the skip bucket 13 is lowered to a certain position below the discharge opening 6 of the hoister 2; the telescopic cylinder 8 extends to enable the opening of the coal guide groove 7 to fall above the coal charging opening of the skip bucket 13; starting the hoister 2 to lift coal or water, and finally discharging the coal or water into a skip 13 through a discharge port 6 and a coal guide groove 7; after the shaft bottom of the vertical shaft 1 is cleaned, the hoisting machine 2 is closed, and the telescopic cylinder 8 is contracted.

Further, the elevator 2 may adopt a multi-medium structure in the prior art, and preferably adopts a bucket elevator. The bucket elevator is a common lifting device, and mainly comprises a driving wheel 21, a directional wheel 22 and a coal extraction bucket 23, wherein the driving wheel 21 drives the directional wheel 22 to rotate through a traction piece 24 (a chain or a belt), and the coal extraction bucket 23 is arranged on the traction piece 24. The driving wheel 21 drives the traction piece 24 to rotate, the coal lifting bucket 23 scoops up coal or water, the coal or water is lifted to the top along with the traction piece 24, the coal or water bypasses the driving wheel 21 at the upper part and turns downwards, the coal or water is thrown into the coal guide groove 7, and the coal or water falls into the skip bucket 13 from the opening of the coal guide groove 7.

Further, when the amount of water flowing down is large, coal slurry is easily formed with the coal scattering on the inclined chute 3, so that the water slides down slowly and is easily deposited. Therefore, a scraper, a rock loader or other similar equipment can be arranged on the inclined chute 3 to assist the coal slime to slide downwards. Whether the scraper and the rock loader are arranged or not is determined according to actual working conditions.

further, as shown in fig. 2 to 5, an adjusting mechanism 9 is arranged at the bottom of the vertical shaft 1, the adjusting mechanism 9 is located below the bottom of the hoist 2, the adjusting mechanism 9 includes a base 10 and a top seat 11, the top seat 11 is slidably coupled with the base 10, an adjusting telescopic cylinder 12 is arranged between the top seat 11 and the base 10, and two ends of the adjusting telescopic cylinder 12 are respectively coupled (fixedly coupled or hinged) with the top seat 11 and the base 10. The movement of the top base 11 relative to the base 10 can be realized by adjusting the extension and contraction of the telescopic cylinder 12. Coal and water are gathered on the top seat 11 through the inclined chute 3 and the drainage slope 4, when the coal and the water are gathered more, large resistance is generated to the operation of the elevator 2, and at the moment, the top seat 11 can be adjusted downwards to play a role in reducing the height and reducing the resistance; when there is less convergence, the top base 12 can be adjusted upward. The up-and-down adjustment is realized by the expansion and contraction of the expansion cylinder 12.

Similarly, the adjusting telescopic cylinder 12 may be an air cylinder or an oil cylinder, or may be an electric push rod.

Further, the top of the top seat 11 is a concave arc, which is beneficial to gathering coal and water.

Further, the upper end of the base 10 is provided with a lap joint edge.

Further, the inclined chute 3 is preferably arc-shaped. The specific inclination angle (radian) of the inclined chute can be adjusted and designed according to actual working conditions, and the falling coal can slowly and automatically slide on the inclined chute.

the above description has been made in detail only for the preferred embodiment of the present invention, but the present invention is not limited to the above embodiment, and various changes can be made without departing from the spirit of the present invention within the knowledge scope of those skilled in the art, and all such changes are intended to be encompassed by the present invention.
