Description

Technical Field

[0001] The invention relates to the technical field of spray fans, in particular to a mine mining spray fan. Background Art

[0002] A large amount of dust is generated during dusty work in places such as mining, stone material processing, and gravel crushing. The emission of these dusts is disorderly and unorganized, covering a large area and with a large total amount. They are blown away by the wind outdoors, causing serious environmental impacts. In the existing technology, spray fans are usually used for dust reduction.

[0003] For example, patent CN217300642U proposes a mining spray fan. The rotating sleeve is rotated, and the movable rod is driven to move downward relative to the main body under the action of the thread, so that the fixed cone is inserted into the ground to prop up the device, and the device can be easily leveled at the same time. The screw is driven to rotate by adjusting the handle, so that the movable block slides inside the movable groove, and the fan body is driven to deflect through the connecting rod. At the same time, the rotating disk is rotated to drive the fan body to rotate to achieve multi-angle spraying. The water in the water tank is injected into the annular cavity through the connecting pipe through the water pump, and then it is evenly sprayed by the atomizing nozzle. The driving motor drives the fan blades to rotate to generate wind force, and the atomized water mist is sprayed out to complete the spraying operation.

[0004] The technical solution disclosed in the above patent document realizes multi-angle spraying by inserting a fixed cone into the ground to enhance the stability of the device during spraying, and drives the fan to rotate through a connecting rod. The shortcomings of the solution are: the nozzle aperture cannot be adjusted, and the vertical height of the fan nozzle cannot be adjusted, resulting in that in the complex geographical environment of the mining area, it cannot be fully adjusted to the actual environment to achieve the maximum dust reduction effect.

In the initial state, the slide frame 44 is arranged horizontally to reduce the vertical height of the device for easy movement. When in use, the motor 41 is turned on to drive the driving rod 42 to rotate. Due to the sliding engagement of the electromagnetic clamping block 43 and the slide frame 44, the slide frame 44 rotates to a vertical state. Then, the third electric push rod 51 is turned on to drive the lifting plate 53 to move along the moving groove 52 and to be in contact with the bottom of the slide frame 44, driving the slide frame 44 to rise until the electromagnetic clamping block 43 is located at the bottom of the slide frame 44. Then, the electromagnetic clamping block 43 is turned on to lock the chain on one side, and the driving power supply of the sprocket device 45 is turned on to drive the transmission of the sprocket and chain. The mounting frame 2 and the air duct 3 rise along the slide frame 44 under the action of the electromagnetic clamping block 43 to adjust the vertical position of the air duct 3.

After moving to the specified position, the cone head is driven into the ground by rotating the screw 12 to fix the control box 1.

[0031] When the device is used, according to the environmental needs of the mining area, the slide frame 44 is initially set horizontally to reduce the vertical height of the device for easy movement. When in use, the motor 41 is turned on to drive the driving rod 42 to rotate. Due to the sliding engagement between the electromagnetic clamp 43 and the slide frame 44, the slide frame 44 rotates to a vertical state. Then, the third electric push rod 51 is turned on to drive the lifting plate 53 to move along the moving groove 52 and to be in contact with the bottom of the slide frame 44, driving the slide frame 44 to rise until the electromagnetic clamp 43 is located at the bottom of the slide frame 44. Then, the electromagnetic clamp 43 is turned on to lock the chain on one side, and the driving power of the sprocket device 45 is turned on to drive the transmission of the sprocket and the chain. The mounting frame 2 and the air duct 3 are moved along the slide frame 4 under the action of the electromagnetic clamp 43. 4 rises, and the vertical position of the air duct 3 is adjusted. During the movement of the mounting frame 2, the telescopic rod 13 in the control box 1 is telescoped to maintain the connection relationship with the mounting frame 2. In the initial state, the elastic metal sheet 24 is expanded outward by its own elasticity, and forms a large-caliber nozzle in cooperation with the elastic rubber cloth 25. The second electric push rod 22 drives the ring 23 to move and squeeze the elastic metal sheet 24, and the elastic metal sheet 24 gradually shrinks inward to form a small-caliber nozzle.
