Description

Technical Field

[0001] The utility model relates to the technical field of coal mine excavation, in particular to a spray dust suppression device for coal mine excavation. Background Art

[0002] Coal mining refers to the process of creating or expanding underground tunnels and working spaces through excavation and development during the coal mining process. This process is a key part of coal mining production as it provides the necessary access and working space for subsequent coal mining.

[0003] Specifically, coal mine excavation involves a variety of technologies and methods, including but not limited to the use of tunneling machines, drilling and blasting, bolting and shotcreting to excavate new tunnels, as well as the repair and expansion of existing tunnels through methods such as brushing, roof picks, and bottom drilling. Excavation operations are usually carried out at the interface between coal seams, rock strata, or coal seams and rock strata to more efficiently mine coal resources. In addition, with the advancement of science and technology and the development of coal mining production technology, coal mine excavation technology is constantly being updated and upgraded. For example, more and more coal mines are now adopting comprehensive mechanized excavation technology. By introducing advanced excavation equipment and supporting processes, excavation is mechanized, automated, and intelligent, further improving excavation efficiency and safety.

[0004] However, when the existing technology is actually used, a large amount of dust is generated during coal mine excavation operations due to factors such as coal seam crushing and mechanical equipment operation, which not only seriously endangers the health of workers but also increases the risk of explosions and fires. The traditional spray dust suppression device has a relatively single spray coverage range and angle, which is not convenient to adjust according to the excavation angle and position of the coal mine excavation equipment, making it difficult to meet the needs of safe and efficient production in modern coal mines. Utility Model Content

[0005] The purpose of the present utility model is to provide a spray dust suppression device for coal mine excavation, so as to solve the problem raised in the above background technology that a large amount of dust will be generated during coal mine excavation operations due to factors such as coal seam crushing and mechanical equipment operation, which not only seriously endangers the health of workers, but also increases the risk of explosion and fire. The traditional spray dust suppression device has a relatively single spray coverage range and angle, which is not convenient to adjust according to the excavation angle and position of the coal mine excavation equipment, and thus it is difficult to meet the needs of safe and efficient production in modern coal mines.

[0007] The transmission gear of the upper end is meshed with the gear of the driven gear, and the transmission gear of the driven gear is meshed with the gear of the driven gear.

[0008] Preferably, fixing holes are formed through the four corners of the mounting base, and there are four fixing holes, which are symmetrically distributed at the four corners of the mounting base.

[0009] Preferably, the bottom of the water pumping pipe passes downward to the bottom of the water tank.

[0010] Preferably, the transmission gear ring is fixedly mounted on the outer curved surface of the rotating base.

[0013] Preferably, the water inlet at the rear end of the spray head is connected to the water outlet of the water pump through a connecting hose.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. When water is pressurized and discharged into the spray head, the spray head will atomize and spray the water forward. When the water is atomized and sprayed forward, the blower fan is turned on by control. When the blower fan is turned on, the atomized water will be sprayed forward along the inside of the spray barrel. When the atomized water is sprayed forward along the inside of the spray barrel, the rotating motor is turned on by control. When the rotating motor is turned on, it will drive the transmission gear to rotate. When the transmission gear rotates, it will engage and drive the transmission gear ring to rotate. When the transmission gear ring rotates, it will drive the rotating base to rotate horizontally. When the rotating base rotates horizontally, it will synchronously drive the spray barrel to swing horizontally to spray, thereby achieving spray dust reduction while being able to adjust the spray position by horizontal swing.

[0016] 2. The utility model also controls to start the first swing motor. When the first swing motor is turned on, it drives the first swing arm to swing up and down. When the first swing arm swings up and down, the second swing motor is controlled to start. When the second swing motor is turned on, it drives the second swing arm to swing up and down. When the first swing arm and the second swing arm swing up and down, the spray barrel can be synchronously driven to swing back and forth to extend or swing and retract. The electric telescopic rod is controlled to start. When the electric telescopic rod is turned on, it drives the swing platform to swing up and down. When the swing platform swings up and down, it drives the spray barrel to swing up and down to adjust the spray angle, thereby realizing that the spray barrel can swing back and forth to extend or swing and retract while swinging up and down to adjust the spray angle, so that the spray barrel can achieve the effect of multi-angle and multi-position spray dust reduction.
