Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The conveying device for coal mine coal preparation as shown in fig. 1 and 2 comprises a feeding channel 1, wherein a spiral feeding shaft 11 is arranged in the feeding channel 1, the spiral feeding shaft 11 is connected to an output end of a first motor 12, a feeding port 13 is arranged at the upper end of the front side of the feeding channel 1, a discharging port 14 is arranged at the lower end of the tail part of the feeding channel 1, a plurality of discharging ports 2 are sequentially arranged on the bottom wall of the feeding channel 1, a plurality of feeding rollers 21 are arranged in the discharging ports 2, the feeding rollers 21 are sequentially and equidistantly spaced in the discharging ports 2, and the mutual distances among the plurality of feeding rollers 21 in the discharging ports 2 are sequentially increased from front to back, the feeding rollers 21 are arranged on a driving wheel 22, the driving wheel 22 is connected with a driving wheel 24 through a driving belt 23, and the driving wheel 24 is connected to an output end of a second motor 25.
In a preferred embodiment, the feeding channel 1 is obliquely supported by the support frame 15, and the feeding channel 1 is obliquely supported, so that coal blocks can be conveyed and screened more conveniently.
As a preferred embodiment, the feeding roller 21 is flush with the inner side end of the discharge opening 2, so that the rotation of the feeding roller 21 can better promote the forward conveying transmission for pushing the screened coal briquettes, and can avoid the coal briquettes from being stuck in the discharge opening 2.
In a preferred embodiment, the driving wheel 22 and the driving wheel 24 are both chain wheels.
The utility model provides a conveying device for coal mine coal dressing when sorting the coal mine piece to the exploitation, send into it in pay-off passageway 1, in its in-process of transportation, carry out the screening coal dressing of the coal mine piece of different granularity size through a plurality of discharge openings 2 that set up.
After the coal lump material is fed from the feeding port 13, the first motor 12 drives the spiral feeding shaft 11 to rotate, so that the coal lump is conveyed, and in the conveying process, the coal lump material sequentially passes through the discharging ports 2 on the feeding channel 1 from top to bottom to be screened.
During the coal dressing, second motor 25 drive action wheel 24 rotates, and under the transmission of driving belt 23, control drives each feed roll 21 synchronous rotation from driving wheel 23, again because of in discharge opening 2, has certain interval between the adjacent feed roll 21, and then through this interval that exists between feed roll 21, screens the coal mine lump material of different granularities. The granularity is less than this interval then through discharge opening 2, outside the screening, the granularity is big, then under feed roll 21's rotation, drives it and continues to carry forward, via next discharge opening 2 department, between the bigger feed roll 21 of interval, carries out screening coal dressing once more.
The above-described embodiments are merely illustrative of the preferred embodiments of the present invention and are not intended to limit the spirit and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by the technical solution of the present invention by those skilled in the art should fall into the protection scope of the present invention, and the technical contents claimed by the present invention have been fully recorded in the claims.
