DETAILED DESCRIPTION

[0025] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] See also Figure 1 , Figure 2 and Figure 3 As shown, a device for suppressing dust from road excavation comprises a body 1, a lifting rack 3 arranged on the body 1 for installing a water spray pipe 2, and a driving adjustment mechanism 4 arranged on the body 1 for limiting the vertical sliding adjustment of the lifting rack 3, the driving adjustment mechanism 4 comprises a gear 41 for sliding the lifting rack 3 in the vertical direction and a rotating handle 42 for driving the gear 41 to rotate, the device for suppressing dust from earth excavation also comprises a locking mechanism 5 for fixing the position of the lifting rack 3 and a filtering mechanism 6 for collecting and purifying dust, the lifting rack 3 is provided with an installation groove for installing a connecting pipe 44, the connecting pipe 44 is a telescopic pipe, which is convenient for extending movement, the body 1 can be provided with a water pipe connecting port for supplying water to a water tank 441, a closed rotating cover can be provided on the connecting port, and the closed rotating cover can be used to close the water pipe connecting port to effectively prevent dust and garbage from entering.

[0027] When dust reduction treatment is required for the dust-contaminated area, the submersible water pump 442 is started and the water in the water tank 441 is transported and sprayed through the connecting pipe 44 and the water spray pipe 2 to achieve the dust reduction effect. When the height of the dust reduction needs to be adjusted, the meshing lifting rack 3 is driven to slide in the vertical direction by rotating the gear 41. When the lifting rack 3 slides, the height of the water spray pipe 2 can be adjusted in the vertical direction, which is convenient for adapting to dust reduction work in different dust-contaminated areas.

[0028] See also Figure 3 and Figure 5As shown, the driving and adjusting mechanism 4 also includes a mounting sleeve 43 and a connecting pipe 44; the mounting sleeve 43 is arranged on the machine body 1; the connecting pipe 44 is arranged on the machine body 1 and is fixedly connected to the lifting rack 3, the other end of the connecting pipe 44 is connected to the water spray pipe 2, and the mounting sleeve 43 is provided with a travel groove for the vertical square sliding of the lifting rack 3, and the machine body 1 is provided with a water tank 441 for supplying water to the connecting pipe 44 and the water spray pipe 2, and a submersible water pump 442 is arranged in the water tank 441, and the submersible water pump 442 is also provided with a suction pipe for supplying water to the connecting pipe 44.

[0029] When dust reduction work is required at the construction site, the submersible water pump 442 in the water tank 441 is started, and the water in the water tank 441 can be sprayed out through the connected connecting pipe 44 and the water spray pipe 2 through the water suction pipe. At this time, the water supply work to the connecting pipe 44 and the water spray pipe 2 can be completed.

[0030] See also Figure 3 , Figure 4 and Figure 5 As shown, the driving adjustment mechanism 4 also includes a transmission rod 45 ; the transmission rod 45 is rotated and arranged on the body 1 , the transmission rod 45 is coaxially fixed with the gear 41 , and the other end of the rotating handle 42 is fixedly connected to the transmission rod 45 .

[0031] When dust reduction work is required in dust areas at different heights, first, the user covers the rotating handle 42 with his hand and rotates it. When the rotating handle 42 rotates, it can drive the transmission rod 45 coaxially fixed therewith to rotate, and then the gear 41 coaxially fixed therewith the transmission rod 45 can rotate synchronously. When the gear 41 rotates, it can drive the lifting rack 3 meshing with it to slide upward. When the lifting rack 3 moves upward, it can drive the connecting pipe 44 fixed thereto to move upward synchronously. Since the connecting pipe 44 is a telescopic pipe, it can drive the connecting pipe 44 to be telescopic when the lifting rack 3 moves, so as to achieve the lifting and lowering of the water spray pipe 2, which is convenient for targeted spraying and dust reduction in dust-contaminated areas in different areas, thereby improving the applicability of the device.

[0032] See also Figure 5 and Figure 7 As shown, the locking mechanism 5 includes a mounting plate 51 and a slide rod 52; the mounting plate 51 is arranged on the mounting sleeve 43; the slide rod 52 is arranged on the mounting plate 51 for linear horizontal sliding, and a return spring 521 is sleeved on the slide rod 52, and the two ends of the return spring 521 are respectively fixed to the ends of the mounting plate 51 and the slide rod 52, and a pulling block is arranged at the other end of the slide rod 52, and the pulling block is circular in shape.

[0033] When the height of the lifting rack 3 needs to be adjusted, the operator first holds the pulling block and pulls the slide bar 52 outward. This action compresses the reset spring 521. The slide bar 52 is continuously pulled until it is completely out of contact with the lifting rack 3. At this time, the slide bar 52 no longer interferes with the rising action of the lifting rack 3. After the height adjustment of the lifting rack 3 is completed, the slide bar 52 is released. The elastic force of the reset spring 521 causes the slide bar 52 to automatically reset, contact the lifting rack 3 again, and engage and fix it, thereby locking the lifting rack 3. This design not only provides the lifting and locking function of the lifting rack 3, but also ensures that the water spray pipe 2 will not fall freely during the spraying process due to the lack of positioning of the lifting rack 3.

[0034] See also Figure 7 As shown, the locking mechanism 5 further includes a block 53 ; the block 53 is disposed on the slide bar 52 and close to one side of the lifting rack 3 , and the shape of the block 53 is a trapezoidal block that better fits the gap between the lifting racks 3 .

[0035] When the slide bar 52 moves, it can drive the block 53 fixed thereto to move relatively closer to and farther from the lifting rack 3, so as to fix the position of the lifting rack 3 after lifting.

[0036] See also Figure 2 , Figure 6 and Figure 8 As shown, the filtering mechanism 6 includes a vacuum generator 61 and a dust box 62; the vacuum generator 61 is arranged on the machine body 1 and away from the side of the mounting sleeve 43; the dust box 62 is arranged on the machine body 1, the air inlet end of the vacuum generator 61 is connected to an air suction pipe 63 fixed to the dust box 62, the dust box 62 is provided with a plurality of through holes for dust to enter, a sponge block 64 for absorbing dust is arranged in the dust box 62, and the water outlet end of the submersible water pump 442 is connected to a water outlet pipe 65, which passes through It passes through and extends into the dust box 62. Several atomizing nozzles can be connected to the water outlet pipe 65 to atomize the water in the water tank 441 and spray it into the dust box 62. A mounting closure plate 66 is slidably provided on the dust box 62 to close the dust box 62 when there is no need to clean or replace the sponge block 64. A pair of connecting plates 67 are provided on the mounting closure plate 66. The connecting plates 67 are provided with pin holes. By inserting the insertion rod 68 into the pin holes, the mounting closure plate 66 and the dust box 62 can be fixedly connected.

[0037] When the dust removal area needs to be vacuumed, the vacuum generator 61 is started to suck the dust in the air into the dust box 62 through the suction pipe 63. At the same time, the submersible water pump 442 works to atomize the water in the water tank 441 through the water outlet pipe 65 and the atomizing nozzle and then spray it into the dust box 62. The water mist contacts the dust, causing the dust to fall onto the sponge block 64. Under the wetting effect of the atomizing nozzle, the sponge block 64 can more effectively absorb and fix the dust thereon. When the sponge block 64 in the dust box 62 needs to be cleaned or replaced, it is only necessary to pull the plug rod 68 out of the latch hole, and then slide the mounting closure plate 66 out of the dust box 62, so that the sponge block 64 can be easily taken out for cleaning or replacement for recycling.
