[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model embodiment discloses a mine mining spray fan.

[0027] The utility model provides Figure 1-3A mining spray fan shown includes a mobile frame 1, a pushing handle 24 is fixedly provided on the upper end of the outer wall of the mobile frame 1, a driving shaft 2 is rotatably passed through the top of the mobile frame 1, a fan body 3 is fixedly provided on the top of the driving shaft 2, a water tank 4 is fixedly provided at the lower end of the mobile frame 1, a water pipe 5 is connected to the top of the water tank 4, the water pipe 5 is a hose, a water pump 6 is fixedly sleeved on the pipe wall of the water pipe 5, the top of the water pipe 5 passes through the fan body 3 and is fixedly connected to the top of the inner wall of the fan body 3, a spray head 7 is connected to the pipe wall of the water pipe 5, two symmetrically arranged fixed plates 8 are fixedly provided at both ends of the bottom of the mobile frame 1, a cross bar 9 is rotatably passed through the two fixed plates 8 on the same side, and walking wheels 10 are fixedly sleeved on both ends of the cross bar 9.

[0028] Before spraying the inside of the mine, water is added to the water tank 4, and the fan body 3 is started so that the fan body 3 starts to blow air. At the same time, the water pump 6 is started to suck the water in the water tank 4 into the water pipe 5 and eject it outward in the form of mist through the spray head 7. At the same time, under the action of wind, the mist is transported to the inside of the mine and the dust is quickly contacted and reduced. Then the operator pushes the mobile frame 1 with the support of multiple walking wheels 10 by holding the pushing handle 24, and during the pushing process, the driving shaft 2 drives the fan body 3 to rotate through the driving of the walking wheels 10, so that the fan body 3 swings back and forth laterally without the help of external energy, thereby increasing the spray range and the walking distance of the device.

[0029] In order to drive the fan body 3 to perform stable lateral reciprocating swing when the running wheel 10 rotates, Figure 1-3 As shown, the lower end of the driving shaft 2 is provided with a swinging spray mechanism for driving the fan body 3 to reciprocate, and the swinging spray mechanism includes a reciprocating screw rod 11, and the reciprocating screw rod 11 is rotatably connected to the upper end of the inner wall of the moving frame 1, and the rod wall of the reciprocating screw rod 11 is threadedly sleeved with a rack 12, and the rack 12 contacts the top of the inner wall of the moving frame 1 and is meshed with a circular gear 13, and the circular gear 13 is fixedly sleeved on the outer lower end of the driving shaft 2;

[0030] A mounting plate 14 is fixedly provided at the upper end of the inner wall of the movable frame 1, a rotating rod 15 is rotatably penetrated inside the mounting plate 14, a bevel gear 16 is fixedly provided at one end of the rotating rod 15 and the reciprocating screw rod 11, and the two bevel gears 16 are meshed, and a first pulley 17 and a second pulley 18 are fixedly provided at the rear ends of the rotating rod 15 and the cross bar 9, respectively, and a belt 19 is provided for transmission between the first pulley 17 and the second pulley 18.

[0031] When the traveling wheel 10 is driven to rotate, the rotating rod 15 rotates synchronously with the internal cross bar 9 of the traveling wheel 10 through the transmission of the first pulley 17, the second pulley 18 and the belt 19. At this time, under the meshing of the two bevel gears 16, the reciprocating screw 11 and the rotating rod 15 rotate simultaneously, so that under the drive of the reciprocating screw 11, the rack 12 moves back and forth laterally under the sliding limit at the top of the inner wall of the moving frame 1. Since the rack 12 is meshed with the circular gear 13, the circular gear 13 can be meshed with the reciprocating movement of the rack 12 to drive the drive shaft 2 to rotate back and forth, so that the drive shaft 2 drives the fan body 3 to swing back and forth.

[0032] In order to be able to monitor the remaining water in the water tank 4 in a timely and intuitive manner during the spraying process, Figure 1 As shown, a water inlet is provided at the top of the water tank 4, a vertical rod 20 is passed through the water inlet, a floating plate 21 is fixedly provided at the bottom of the vertical rod 20, a scale plate 22 is fixedly provided at the top of the water tank 4, a sliding sleeve 23 is provided on the outer sliding sleeve of the scale plate 22, and the sliding sleeve 23 is fixedly connected to the top of the vertical rod 20.

[0033] When the water tank 4 is full of water, the float plate 21 is pushed by the buoyancy of the water and is located at the uppermost end of the water tank 4. At this time, under the support of the vertical rod 20, the sliding sleeve 23 is also located at the upper end of the scale plate 22. During the continuous spraying process, the water continues to decrease. At this time, under the action of the gravity of the float plate 21, the float plate 21 drives the sliding sleeve 23 to start moving downward. When the sliding sleeve 23 is located at a lower position than the scale plate 22, the remaining water in the water tank 4 is insufficient and needs to be added in time to ensure that the spraying work can be carried out stably and continuously.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
