[0002] As people's requirements for living environment standards continue to increase, they have gradually realized that environmental protection is of great significance to improving environmental quality. At this stage, whether it is road construction, house construction, or mining, a large amount of flying dust will be generated.

[0024] In the above method, in order to extract clean water, a water pump 11 is fixed on the water tank 2, and one end of a water pumping pipe 12 is fixed on the water inlet thereof, and the other end of the water pumping pipe 12 is fixedly connected to one side of the water tank 2, and one end of a bellows 13 is fixed on the water outlet of the water pump 11, and the other end of the bellows 13 extends into the transfer tube 10 and is rotatably connected to the transfer tube 10, and the bellows 13 passes through one side of the frame 9 and is fixedly connected to one side of the frame 9, thereby ensuring that the frame 9 can be smoothly raised and lowered.

[0025] In this embodiment, in order to support the double-sided rack 18 and the motor 20, a load-bearing plate is fixed on the top column 8, and an avoidance hole is opened on the load-bearing plate, and the bellows 13 passes through the avoidance hole, so as not to hinder the stretching of the bellows 13, and a cross plate is fixed on the top of the load-bearing plate, and the bottom of the motor 20 set above is fixedly connected to the cross plate, and a concave seat 15 is fixed on the top of the cross plate, and two connecting rods 16 are fixed in the concave seat 15, and the two connecting rods 16 The same slide plate 17 is installed on the upper slide, and the top of the slide plate 17 is fixedly connected to the double-sided rack 18.

The top of the slider extends to the top of the support plate and is fixed with a support column, and the top of the support column is fixedly connected to the water outlet pipe 3.

[0028] The working principle of the dust suppression equipment provided by the utility model is as follows:

[0029] When dust suppression work is required, first pour a sufficient amount of clean water into the water tank 2, then start the water pump 11, the water pump 11 begins to extract clean water, and the clean water enters the water outlet pipe 3 through the water suction pipe 12, the bellows 13 and the transfer pipe 10 in turn, and then is sprayed out through the nozzle 4 to form water mist. Then, start the motor 20, and its output shaft drives the toothed gear 21 to rotate. When the teeth on it contact one side of the double-sided rack 18, the two form a meshing, thereby driving the double-sided rack 18 to move longitudinally. At the same time, the teeth on the other side of the double-sided rack 18 will mesh with the full-tooth gear 14, thereby driving the full-tooth gear 14 to rotate, which can drive the transfer pipe 10 and the water outlet pipe 3 to rotate, so that the nozzle 4 starts to move to one side. The toothed gear 21 is in contact with the toothed gear 18, and the return spring 19 is in a compressed state. Then, when the teeth of the toothless gear 21 are separated from the teeth of one side of the double-sided rack 18, the compressed return spring 19 loses its restriction and then automatically rebounds, thereby driving the double-sided rack 18 in the opposite direction, and then causing the full-tooth gear 14 to rotate in the opposite direction, so that the nozzle 4 rotates back until the teeth of the toothless gear 21 are in contact with the teeth of the double-sided rack 18 again, which drives the nozzle 4 to rotate again. After that, in this way, under the continuous operation of the motor 20, the nozzle 4 forms a forward and reverse reciprocating motion, thereby performing water spraying and dust reduction work in a swinging posture, and then pulling the carrier 1, the mobile left-right swinging dust reduction work can be performed, thereby increasing the dust reduction range;

[0030] In subsequent use, if the dust height is high, in order to adapt to the dust reduction height, motor 2 can be started, and its output shaft will drive the adjusting screw 6 to rotate, and then through its threaded cooperation with the lifting plate 7, the top column 8 can be driven to rise, thereby being able to bring the water outlet pipe 3 and the nozzle 4 up, until the nozzle 4 rises to the specified height, then turn off motor 2, and then continue the spraying dust reduction work.

[0031] Compared with the related art, the dust reduction equipment provided by the utility model has the following beneficial effects:

[0032] The utility model provides a dust reduction device. Through the meshing cooperation of the toothless gear 21, the full-tooth gear 14 and the double-sided rack 18, the water outlet pipe 3 and the nozzle 4 can be swung back and forth left and right, so that a swinging spray dust reduction operation can be performed. This can increase the dust reduction range to a certain extent, and further enhance the dust reduction effect. Moreover, through the threaded cooperation between the adjusting screw 6 and the lifting plate 7, the height position of the nozzle 4 can be adjusted according to actual needs, so as to meet the dust reduction work in different situations, and the applicability is strong.
