Description

Technical Field

[0001] This utility model relates to the field of dust suppression spraying technology in coal mines, and in particular to a dust suppression and environmental protection spraying device for coal mine civil engineering. Background Technology

[0002] A search revealed a Chinese patent with authorization number CN220047573U, which discloses a dust control and environmental protection spraying device for coal mine civil engineering. This device effectively solves problems such as difficulty in adjusting the spraying angle and low spraying efficiency. It includes a housing with support plates fixed to its front and rear sides. A movable plate is mounted on the housing, with its right end hinged to the support plates. Multiple nozzles are installed on the movable plate. The housing contains a first chamber and a second chamber. A rotating shaft arranged in a front-rear direction is rotatably connected within the first chamber, and a gear is coaxially fixed to the rotating shaft. A rack that meshes with the gear is slidably connected vertically within the housing. A frame located above the housing is fixed to the upper end of the rack, and rollers are hinged to the front and rear ends of the frame. The lower surface of the movable plate has sliding grooves that cooperate with the rollers. The rollers move along the sliding grooves, thereby controlling the rotation of the movable plate. The nozzles are connected to the second chamber via water pipes.

[0003] The dust control and environmental protection spraying device for coal mine civil engineering in the above patent has the following shortcomings: Although the movable plate is rotated, the angle of the multiple nozzles on the movable plate remains consistent, resulting in the spraying range remaining unchanged during use. It is impossible to adjust the local nozzles. When it is necessary to spray a local area, it cannot be adjusted, which will reduce the effectiveness of the device. Therefore, the above problems need to be solved. Utility Model Content
