Description

Technical field

[0001] The invention relates to the technical field of road maintenance equipment, in particular to a ground full-wetting dust prevention equipment. [Background Technology]

[0002] Currently, in the field of road maintenance, due to the increasing severity of dust pollution, effective dust prevention measures are needed. At this time, ground wetting dust prevention equipment is needed to wet the ground, reduce dust flying, and thus reduce the harm of dust to workers' health. It can also reduce the problems of shortened equipment service life and increased failure rate. Therefore, ground wetting dust prevention is an indispensable safety measure in road maintenance and is of great significance for protecting personnel health and construction safety. There are many types of ground wetting dust prevention equipment on the market, but the water spraying range of these devices is usually very limited and cannot cover a large area. Moreover, the spraying mechanism of these devices is not set up properly and cannot spray water mist evenly, resulting in insufficient wetting in some areas and excessive wetting in others. In addition, existing ground wetting dust prevention equipment has some other problems. For example, the nozzle angle of some devices cannot be adjusted and cannot be adjusted according to actual needs, resulting in a limited spraying range. To solve the above problems, there is an urgent need for a ground wetting dust prevention device with a multi-directional and uniform spraying function. [Summary of the invention]

[0022] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] Example 1: Please refer to the attached Figure 1 To the attached Figure 5 The present embodiment provides a ground-wide wetting and dust-prevention device, comprising a frame 1, a water tank 2 mounted on the frame 1, and a spraying mechanism 3 connected to the water tank 2. The spraying mechanism 3 comprises a first flow guide 31 and a second flow guide 32 correspondingly arranged. The first flow guide 31 is provided with a first flow guide surface 3101, and the second flow guide 32 is provided with a second flow guide surface 3201 arranged opposite to the first flow guide surface 3101. A diffuser cavity 33 for water flow to pass through is formed between the first guide surface 3101 and the second guide surface 3201, and the opening of the diffuser cavity 33 is circumferentially arranged. The ground comprehensive wetting and dust prevention equipment of the present invention adopts the cooperation of the first guide member 31 and the second guide member 32 to form a diffusion cavity 33 between the relatively arranged first guide surface 3101 and the second guide surface 3201. When the water flows into the diffusion cavity 33, it will be squeezed by the first guide surface 3101 and the second guide surface 3201 and will be scattered and sprayed along the circumference of the diffusion cavity 33, thereby achieving the effect of all-round spraying and wetting of the ground and maximizing the spraying range of the spraying mechanism.

[0024] The first flow guide 31 includes a first flow guide tube 311, and the second flow guide 32 includes a second flow guide tube 321. The second flow guide tube 321 is nested outside the first flow guide tube 311, forming an annular flow channel 34 for water flow between the outer wall of the first flow guide tube 311 and the inner wall of the second flow guide tube 321. One end of the annular flow channel 34 connects to the water storage tank 2, and the other end connects to the diffuser chamber 33. The water storage tank 2 provides water to the spray mechanism 3 through the annular flow channel 34. The water flows through the annular flow channel 34 to the center of the diffuser chamber 33, and is then sprayed out from the diffuser chamber 33 in a circumferential direction.

[0025] The first flow guide 31 also includes a first flow guide plate 312 connected to one end of the first flow guide tube 311. The second flow guide 32 also includes a second flow guide plate 322 connected to one end of the second flow guide tube 321. The first flow guide surface 3101 and the second flow guide surface 3201 are located on the first flow guide plate 312 and the second flow guide plate 322, respectively. The spray mechanism 3 also includes a second driving member 36 for driving the second flow guide 32 to move vertically on the frame 1. When the second driving member 36 drives the second flow guide 32 to move closer to the first flow guide 31, the second flow guide surface 3201 approaches and abuts the first flow guide surface 3101, thereby closing the diffusion chamber 33. The abutment between the first flow guide surface 3101 and the second flow guide surface 3201 closes the diffusion chamber 33, and the spray mechanism 3 is now released from the omnidirectional scattering state.

[0026] The second guide plate 322 defines a second spray slot 3221 on the second guide surface 3201. When the diffusion cavity 33 is closed, one end of the second spray slot 3221 communicates with the annular flow channel 34, while the other end forms a second nozzle 3222 facing the outside. When the spray mechanism 3 stops its omnidirectional scattering mode, the second spray slot 3221 allows water to be sprayed out, and the spray mechanism 3 now operates in a concentrated spraying mode.

[0027] The first guide plate 312 is provided with a first injection groove 3121 on the first guide surface 3101. When the diffuser cavity 33 is retracted, one end of the first injection groove 3121 is connected to the annular flow channel 34, and the other end forms a first nozzle 3122 facing the outside. The spraying mechanism 3 also includes a first driving member 35 for driving the first guide member 31 to rotate axially around the first guide tube 311 on the frame 1. When the first driving member 35 drives the first guide member 31 to rotate to drive the first guide plate 312 to rotate, the first injection groove 3121 remains connected to the annular flow channel 34 and rotates around the axis, causing the first nozzle 3122 to rotate circumferentially around the first guide plate 312. The ground full wetting dust prevention equipment of the present invention adopts a rotatably arranged first guide member 31, which cooperates with the first injection groove 3121 connected to the annular flow channel 34 on the first guide member 31. When the spraying mechanism 3 is switched to a centralized spraying state after the second guide surface 3201 abuts the first guide surface 3101, the rotation of the first guide member 31 drives the first injection groove 3121 to swing, so that the centralized spraying direction of the spraying mechanism 3 can achieve an all-round adjustment effect.

[0028] A telescopic link 11 is movably mounted on the vehicle frame 1. One end of the telescopic link 11 is connected to the surface of the second deflector plate 322 facing away from the second deflector surface 3201. This link 11 is used to vertically move the second deflector 322, thereby moving the second deflector plate 322 toward or away from the first deflector plate 312. The telescopic link 11 can be driven by a second drive member 36, which can be either electrically or hydraulically driven, ensuring more stable lifting and lowering of the second deflector 32.

[0029] The first guide member 31 and the second guide member 32 are both located at the bottom of the vehicle frame 1, and the height of the second guide plate 322 is higher than the first guide plate 312. This arrangement is conducive to the arrangement of the dust removal mechanism 4 in terms of structural design.

[0030] The fully wetted floor dust prevention device also includes a dust removal mechanism 4, comprising a sweeping disc 41 and a coupling shaft 42 connected thereto. The sweeping disc 41 is located below the first guide plate 312 and is provided with a plurality of brush strips 411 that abut the floor. The spraying mechanism 3 also includes a third drive member 37 for driving the coupling shaft 42 to rotate axially on the frame 1. The third drive member 37 drives the coupling shaft 42 to rotate, thereby driving the sweeping disc 41 to rotate about its axis. The provision of the dust removal mechanism 4, which utilizes the brush strips 411 of the sweeping disc 41 to clean the floor, further enhances the dust prevention effectiveness of the device.

[0031] The first guide tube 311 is hollow, and the connecting shaft 42 passes through the inner side of the first guide tube 311, so that the sweeping disc 41 and the first guide disc 312 rotate coaxially, making the spraying mechanism 3 and the dust removal mechanism 4 more compact in structure.

[0032] The water tank 2 is connected with an extension pipe 21, and one end of the extension pipe 21 away from the water tank 2 is connected with a water gun 22. The water gun 22 can be used for various local flushing needs, expanding the functionality of the water tank 2.

[0033] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
