The fully-mechanized mining support 1 in the figure is only for illustration and is composed of an upper plate seat and a lower plate seat, and the two are fixedly connected through a plurality of circular vertical rods. The water tank is fixedly arranged on the lower plate seat. At the same time, in the specific setting process, the circular vertical rods can also be set as cylinders and telescopic rods, and the corresponding telescopic rods can be driven to expand and contract by the operation of the cylinders, so as to control the angles of spraying and dust removal; but at this time, the pipes fixedly connected to the water tank 21 subsequently need to be set as flexible hoses.
[0045] The hood cylinder 3 is hollow with both ends communicating, used to protect the dust removal part. A filter screen plate is fixedly installed on one side of the hood cylinder 3. The filter screen plate can be installed on the hood cylinder 3 by a detachable fixing method, such as threaded connection. Further, the outer surface of the filter screen plate can be set to be inclined. At the same time, a detachable collection cylinder is fixedly communicated with the hood cylinder 3, which is convenient for collecting larger impurities collected from the filter screen plate and facilitating regular treatment. On the other side of the hood cylinder 3, a control plate 9 is fixedly installed. The control plate 9 can be integrally formed with the hood cylinder 3, or the hood cylinder 3 can be set to have one end open, and the unopened side is the control plate 9. The separate naming here is for the convenience of subsequent understanding. The control plate 9 is rotatably installed with a fan 5 through a rotating shaft 4. The rotating shaft 4 is rotatably installed on the control plate 9, and the fan 5 is fixedly installed on the rotating shaft 4. When the rotating shaft 4 rotates, it can drive the fan 5 to rotate, thereby sucking external dust, or during spraying, using the air flow generated by the rotation of the fan 5 to assist spraying.

At this time, the elastic telescopic rod 12 is subject to centrifugal force and expands and contracts under the action of the centrifugal force. At the same time, when the centrifugal force decreases, due to its own elastic function, it will automatically adaptively shorten. Other existing structures can also be used to replace the elastic telescopic rod 12; The elastic shielding assembly includes a shielding block 13 and an elastic connecting block 14. A shielding block 13 is fixedly installed at the end of each elastic telescopic rod 12 away from the rotating shaft 4.

A plurality of fixed support rods are fixedly installed on the cover cylinder 3, and the atomizing water pipe 28 is fixedly arranged between the atomizing water pipe 28 and the fixed support rods. In addition, the connection part between the atomizing water pipe 28 and the atomizing nozzle 29 can be set as a flexible pipe, and the rest of the part is still a rigid pipe. An electric telescopic rod is set on the cover cylinder 3. One end of the electric telescopic rod is rotatably connected with the atomizing nozzle 29. The telescopic movement of the electric telescopic rod is used to drive the atomizing nozzle 29 to adjust the angle; the air pipe 20 is used to assist the atomizing nozzle 29 when needed to increase its coverage area. Its air outlet end can also be set as a flexible pipe, and then it can be set as the adjustment of the single air outlet angle, or directly set to be adjusted together with the atomizing nozzle 29. The existing common setting methods are not elaborated here.

The second control component can control the driving and rotating component or the spraying component, and control the operation of the two alone or simultaneously; the second control component includes a rigid blocking structure and a damping limit sliding structure. The rigid blocking structure is installed inside the control cylinder 6 through the damping limit sliding structure.

[0056] Further explanation, the above fixed connection, unless otherwise clearly specified and limited, should be understood in a broad sense. For example, it can be welding, gluing, or integrally formed setting, etc., which are common means well-known to those skilled in the art.
[0057] In the present invention, for the convenience of understanding, the water flow velocity generated by the operation of the water pump 22 is divided into three levels here. The first level has the maximum flow velocity. At this time, the sliding block 31 is in the lowest position, below the impact water pipe 27, and the regulation block 32 is below the atomizing water pipe 28. The second level has a relatively large flow velocity. At this time, the sliding block 31 moves up a certain distance, but does not block or does not completely block the impact water pipe 27, but at this time the atomizing water pipe 28 is completely blocked. The third level has a relatively small flow velocity. The sliding block 31 completely blocks the impact water pipe 27, or is located between the impact water pipe 27 and the atomizing water pipe 28;
[0058] At the first level: The water flowing out of the impact water pipe 27 impacts the blades 26, driving the blades 26 to rotate. The rotation of the blades 26 drives the shaft body 7 to rotate. The rotation of the shaft body 7 drives the rotation of the rotating shaft 4 through the transmission structure 8. The rotation of the rotating shaft 4 drives the fan 5 to rotate. At this time, the rotation speed of the fan 5 is the maximum, the length of the elastic telescopic rod 12 is the longest, and the blocking block 13 blocks the through hole 10. At this time, the wind generated by the operation of the fan 5 flows out from the air duct 20;
[0059] The water flowing out of the atomizing water pipe 28 is atomized and sprayed out through the atomizing nozzle 29. At this time, it can cooperate with the wind flowing out of the air duct 20 to assist the effect of atomized dust suppression;
[0060] At the second level: At this time, the rotation speed of the fan 5 decreases, the length of the elastic telescopic rod 12 shortens, and the shielding block 13 shields the second through hole 11. At this time, the wind generated by the operation of the fan 5 flows out through the first through hole 10, and then flows into the dust removal cloth bag 19 through the first cover 15, the dust inlet pipe 17, and the mounting seat 18 for dust reduction;
[0061] At the third level: At this time, the fan 5 stops rotating, and water is atomized and sprayed out through the atomizing water pipe 28 and the atomizing nozzle 29 for dust reduction alone.
[0062] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
