DETAILED DESCRIPTION

[0020] The utility model aims at the problems existing in the prior art and provides a dust reduction device for a dump truck. The device reduces dust by spraying an aqueous solution, thereby ensuring that a large amount of dust is not generated when unloading goods and reducing environmental pollution.

[0021] See also Figure 1The utility model mainly includes a water tank 3, a water pump 4 and a spray assembly 5. The water tank 3 is fixed at the bottom of the compartment 2 of the dump truck, the water pump 4 is installed in the water tank 3, the spray assembly 5 is installed on the top of the compartment 2, and the spray assembly 5 is connected to the water pump 4 through a water pipe 6, and the water pipe 6 is embedded in the inner wall of the compartment 2.

[0022] See also Figure 2 , Figure 3 The spray assembly 5 includes a protection box 51 fixed on the top of the carriage 2, a nozzle 52 is installed at the bottom of the protection box 51, and the nozzle 52 is connected to the water pump 4 through a water pipe 6. A support plate 53 is fixedly connected to the top opening of the protection box 51, and the edge of the support plate 53 is connected to the inner wall of the protection box 51. A plurality of evenly distributed first water seepage holes 54, second water seepage holes 55 and third water seepage holes 56 are respectively opened in different areas on the support plate 53. The apertures of the three water seepage holes are different. The protection box 51 An annular groove 511 is provided at the upper end of the side wall, and a turntable 57 is rotatably connected between the inner walls of the annular groove 511. The turntable 57 is located at the upper part of the support plate 53, and a water outlet hole 58 is provided on the turntable 57. A coaxial bolt 59 is inserted between the turntable 57 and the support plate 53. The bolt 59 passes through the center hole of the turntable 57 and is threadedly connected with the through hole in the middle of the support plate 53. By rotating the turntable 57, the water outlet hole 58 can be aligned with the first seepage hole 54, the second seepage hole 55 and the third seepage hole 56 respectively.

[0023] A connecting base 571 is fixedly connected to the upper part of the rotating disk 57 . A clamping groove 572 is formed at the upper edge of the connecting base 571 . A protective cover 573 is threadedly connected between the inner walls of the clamping groove 572 .

[0024] The turntable 57 is made of stainless steel, and anti-slip grooves 574 are arranged around the turntable 57 .

[0025] When the dump truck is unloading, the staff first pours an appropriate amount of aqueous solution into the water tank 3, and then starts the water pump 4. The aqueous solution in the water tank 3 is transmitted to the spraying component 5 through the water pump 4 and the water pipe 6 for spraying. The sprayed aqueous solution combines with the dust particles in the air to make the dust fall and avoid a large amount of dust. If the dust particles are too large and a large amount of water needs to be sprayed, the staff can adjust the spraying component 5 to increase the amount and density of water sprayed, which can effectively suppress dust and ensure the safety of construction workers.

[0026] The dust generated when the dump truck unloads is related to the type of bulk material, so the water spraying amount should be adjusted according to the type of bulk material. When the water spraying amount needs to be adjusted, the staff first rotates the bolt 59 so that the turntable 57 can rotate relative to the support plate 53, and then rotates the turntable 57 so that the water outlet 58 on the turntable 57 is aligned with the appropriate water seepage hole on the support plate 53. When the water outlet 58 is aligned with the first water seepage hole 54, a high-density aqueous solution can be sprayed, which is suitable for dust with larger particles; when the water outlet 58 is aligned with the second water seepage hole 55, a medium-density aqueous solution can be sprayed; when the water outlet 58 is aligned with the third water seepage hole 56, an atomized aqueous solution can be sprayed, which is suitable for small particles of dust. After each adjustment of the position of the water outlet 58, the bolt 59 needs to be tightened again to fix the position of the water outlet 58 to avoid deviation during the dust reduction process.

[0027] When dust suppression is not required, in order to prevent dust from the construction site from entering the water outlet 58 and causing the water seepage holes on the support plate 53 to be blocked, after each spraying work is completed, the staff will rotate the protective cover 573 to the inside of the slot 572, and the protective cover 573 will cover the water outlet 58 to prevent dust from entering, thereby extending the service life of the spraying component and improving work efficiency.

[0028] The turntable 57 is made of stainless steel, which is not easily rusted by corrosion from air and aqueous solutions. Meanwhile, anti-skid patterns 574 are provided on the surface of the turntable 57 to increase the friction between the hands of the staff and the turntable 57, making the turntable 57 more convenient.
