Description

Technical Field

[0001] The utility model relates to the technical field of wind protection devices, in particular to a wind erosion prevention and dust suppression device for open-pit coal mines. Background Technique

[0002] When the distance between the coal seam and the ground surface is very close, generally, the surface soil layer is directly stripped to excavate coal, which is an open-pit coal mine. After the coal is mined, it is placed in a coal storage yard for storage. During the stacking process of coal in the coal storage yard, the wind will cause wind erosion on the surface of the coal, and at the same time, dust will be generated. The dust will be transmitted to the atmospheric environment through the external wind force, thus seriously polluting the atmospheric environment. Therefore, a wind erosion prevention and dust suppression device for open-pit coal mines is needed to block the wind, protect the coal and ensure the safety of the atmospheric environment.

[0003] At present, most of the existing wind erosion prevention and dust suppression devices for open-pit coal mines use windbreak and dust suppression nets to block wind and suppress dust. After the position of the windbreak and dust suppression net is fixed, since the size of the ventilation opening remains unchanged, the size of the ventilation opening cannot be adjusted according to the wind force. Therefore, it is impossible to ensure that the ventilation opening can prevent dust from flying and ensure smooth ventilation at the same time, resulting in poor overall wind erosion prevention and dust suppression effect of the device. For this reason, the utility model provides a wind erosion prevention and dust suppression device for open-pit coal mines, and solves the above problems through a driving motor, a T-shaped slide rail and other limiting structures. Summary of the Utility Model

[0013] Beneficial effects

[0014] The utility model provides a wind erosion prevention and dust control device for open-pit coal mines. Compared with the prior art, it has the following beneficial effects:

[0015] (1) By setting a wind sensor in the utility model, the wind force can be sensed. When the wind force is large, the wind sensor will control the driving motor to drive the turntable to rotate a certain distance. The turntable drives the transmission rod to make a circumferential rotation, and the transmission rod drives the L-shaped connecting plate to move horizontally along the T-shaped slide rail, thereby driving the adjustable dust control net to move horizontally along the main body of the windbreak and dust control net. As a result, the through holes of the main body of the windbreak and dust control net and the adjustable dust control net are misaligned, so as to change the size of the through holes on the main body of the windbreak and dust control net, thus improving the effect of windbreak and dust control.

[0016] (2) By setting a fixing component in the utility model, the assembly of the adjustable dust control net can be effectively realized, making the disassembly between the main body of the windbreak and dust control net and the adjustable dust control net convenient and fast. At the same time, by setting a spraying component, the dust can be further reduced, effectively suppressing the spread of dust. Description of the Drawings
