Specific embodiments

[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0015] Please refer to Figures 1 - 9, an embodiment of the present invention is: an adjustable spray device for controlling construction dust, including a box body 1, a water tank 2 is fixedly connected to the bottom of the inner wall of the box body 1; a water pump 6 is installed on the left side of the water tank 2, a support frame 7 is fixedly connected to the bottom of the inner wall of the box body 1, a double-shaft motor 8 is fixedly connected to the upper surface of the support frame 7, a reciprocating screw rod 9 is fixedly connected to the upper end output of the double-shaft motor 8, a limit frame 10 is fixedly connected to the upper surface of the box body 1, a lifting plate 11 is slidably connected to the circumferential surface of the reciprocating screw rod 9, a rack plate 12 is fixedly connected to the left side of the limit frame 10, a groove column 13 is rotatably connected to the front of the lifting plate 11, a nozzle 3 is rotatably connected to the inner wall of the lifting plate 11, a connecting rod 14 is rotatably connected to the upper surface of the nozzle 3, a fixed column 15 is fixedly connected to the right side of the connecting rod 14, a filtering mechanism 4 is arranged on the inner wall of the box body 1, and a cleaning mechanism 5 is arranged on the lower surface of the box body 1. When the device is started, the water pump 6 pumps the water placed in the water tank 2 on the box body 1 through a hose into the nozzle 3 to realize the water spraying of the device. At the same time, the double-shaft motor 8 placed on the support frame 7 is started to drive the reciprocating screw rod 9 to rotate. The rotation of the reciprocating screw rod 9 drives the lifting plate 11 located in the limit frame 10 to move up and down. The up and down movement of the lifting plate 11 drives the nozzle 3 to move up and down, enabling the device to spray up and down, and being able to capture dust from the top and bottom of the space simultaneously. The dust will diffuse throughout the space. By adopting the up and down spraying method, the water droplets can fully contact the dust at different heights, thus greatly improving the dust capture efficiency. Compared with single-direction spraying, it can reduce the dust content in the air more quickly and comprehensively. The upper end of the reciprocating screw rod 9 contacts the inner wall of the limit frame 10, the inner wall of the limit frame 10 contacts the surface of the lifting plate 11, the rack surface of the rack plate 12 meshes with the gear of the groove column 13, the surface of the connecting rod 14 slides in the inner wall of the short plate on the left side of the lifting plate 11, and the right end of the fixed column 15 slides in the groove of the groove column 13. When the lifting plate 11 moves up and down in the device, it drives the groove column 13 to move up and down. Because the gear on the groove column 13 meshes with the rack plate 12 located on the limit frame 10, the up and down movement of the lifting plate 11 drives the gear on the groove column 13 to rotate. Due to the special groove arranged in the groove column 13, the rotation of the groove column 13 drives the fixed column 15 to move back and forth. The back and forth movement of the fixed column 15 drives the connecting rod 14 to move back and forth in the small block on the left side of the lifting plate 11. Since the long rod of the nozzle 3 is elastically telescopic, the connecting rod 14 drives the nozzle 3 to rotate around the lifting plate 11 to realize the rotary spraying of the nozzle 3. The left and right spraying can form a relatively wide spraying area in the horizontal direction, enabling the water droplets to evenly cover a large area of space, greatly improving the dust removal coverage area and effect.

[0016] Working principle: When the device is started, the water pump 6 pumps out the water in the upper water tank 2 placed on the box body 1 through the hose into the nozzle 3, realizing the water spraying of the device. At the same time, the double-shaft motor 8 placed on the support frame 7 starts to drive the reciprocating lead screw 9 to rotate. The rotation of the reciprocating lead screw 9 drives the lifting plate 11 located in the limit frame 10 to move up and down. The up and down movement of the lifting plate 11 drives the nozzle 3 to move up and down, enabling the device to spray water up and down, and being able to capture dust from both the top and bottom of the space. The dust will diffuse throughout the space. By adopting the up and down spraying method, the water droplets can fully contact the dust at different heights, thus greatly improving the dust capture efficiency. Compared with single-direction spraying, it can reduce the dust content in the air more quickly and comprehensively. When the lifting plate 11 moves up and down in the device, it drives the groove column 13 to move up and down. Since the gear on the groove column 13 meshes with the rack plate 12 located on the limit frame 10, the up and down movement of the lifting plate 11 drives the gear on the groove column 13 to rotate. Due to the special grooves provided in the groove column 13, the rotation of the groove column 13 drives the fixed column 15 to move back and forth. The back and forth movement of the fixed column 15 drives the connecting rod 14 to move back and forth in the small block on the left side of the lifting plate 11. Since the long rod of the nozzle 3 is elastically telescopic, the connecting rod 14 drives the nozzle 3 to rotate around the lifting plate 11 to realize the rotary spraying of the nozzle 3. The left and right spraying can form a relatively wide spraying area in the horizontal direction, enabling the water droplets to evenly cover a large area of space, greatly improving the dust removal coverage area and effect.

[0017] Please refer to Figures 1 - 9, on the basis of the above embodiments, in another embodiment of the present invention, the filtering mechanism 4 includes: a first gear 41, a gear set 42, a rack column 43, and a filtering box 44. The lower surface of the first gear 41 is rotatably connected to the upper surface of the box body 1, and the lower surface of the second gear set 42 is rotatably connected to the upper surface of the box body 1. The surface of the rack column 43 slides on the inner wall of the short board on the upper surface of the box body 1. The circumferential surface of the filtering box 44 is fixedly connected to the bottom of the inner wall of the box body 1 through an L-shaped rod. When the double-shaft motor 8 rotates, it drives the first gear 41 to rotate. Since the first gear 41 meshes with the lower gear of the gear set 42, the rotation of the first gear 41 drives the lower gear of the gear set 42 to rotate. The rotation of the lower gear of the gear set 42 drives the upper sector gear in the gear set 42 to rotate. Since the upper sector gear of the gear set 42 meshes with the rack column 43, the rotation of the upper sector gear of the gear set 42 drives the rack column 43 to move backward. When the upper sector gear on the right side of the gear set 42 has completely passed, the upper sector gear on the left side of the gear set 42 just meshes with the rack column 43, driving the rack column 43 to move forward, so that the rack column 43 drives the brush plate to move back and forth on the upper surface of the box body 1, pushing the water on the upper surface of the box body 1 into the small holes opened on the upper surface of the box body 1, and entering the filtering box 44 through the small holes. The activated carbon in the filtering box 44 filters the water and then returns to the water tank 2 again. At the same time, due to the long-term accumulation of waste water and dust, dust condensation may occur on the upper surface of the box body 1, resulting in the device being too dirty. The dust removal waste water usually contains a large amount of dust, particulate matter, etc. Through filtration, most of the suspended particulate matter in the waste water can be effectively removed, thereby realizing the recycling of water resources. The filtering mechanism 4 further includes: a limiting column 45, a stirring fan blade 46, a first fixing plate 47, a first pushing column 48, a second pushing column 49, and a screw rod 410. The bottom end of the screw rod 410 is rotatably connected to the bottom of the inner wall of the filtering box 44. The bottom end of the limiting column 45 is fixedly connected to the upper surface of the box body 1. The inner wall of the stirring fan blade 46 is fixedly connected to the circumferential surface of the screw rod 410. The inner wall of the second pushing column 49 is movably connected to the circumferential surface of the screw rod 410. The surface of the screw rod 410 is provided with a non-self-locking spiral groove. A clamping block is arranged on the inner wall of the second pushing column 49, and the clamping block is located in the non-self-locking spiral groove. The upper surface of the first fixing plate 47 is fixedly connected to the top of the inner wall of the box body 1 through an elastic telescopic column. The bottom of the first pushing column 48 is fixedly connected to the upper surface of the first fixing plate 47. The circular block on the circumferential surface of the reciprocating screw rod 9 contacts the upper surface of the rack column 43. The rack column 43 meshes with the gear set 42. The inner wall of the limiting column 45 contacts the surface of the second pushing column 49. The circumferential surface of the first pushing column 48 slides on the inner wall of the box body 1. The lower surface of the lifting plate 11 contacts the upper end of the first pushing column 48. When the lifting plate 11 of the device moves up and down, it will drive the first pushing column 48 to move up and down. Since the second pushing column 49 is limited by the limiting column 45, the up and down movement of the first pushing column 48 drives the second pushing column 49 and the first fixing plate 47 to move up and down respectively. The up and down movement of the second pushing column 49 drives the screw rod 410 to rotate. The rotation of the screw rod 410 drives the stirring fan blade 46 to rotate. The device can stir the activated carbon in the filtering box 44, increasing the contact area between the activated carbon and the waste water.Thus, the wastewater can be filtered more cleanly.

[0018] The cleaning mechanism 5 includes: a collection box 51, a second fixing plate 52, and a brush disc 53. The collection box 51 is fixedly connected to the lower surface of the box body 1. The back surface of the second fixing plate 52 is fixedly connected to the front surface of the box body 1. The brush disc 53 is rotatably connected to the lower surface of the second fixing plate 52 through a long rod. When the dual-axis motor 8 is started, the output shaft at the lower end will drive the pulley group to rotate. The pulley group drives the brush disc 53 located below the second fixing plate 52 to rotate. The two brush discs 53 are connected through a pulley group. The brush disc 53 rotates to sweep the dirty water sprayed on the road surface and sundries such as stones into the collection box 51, enabling the device to collect substances such as stones at the construction site. Since there are many stones at the construction site, they may block the forward movement of the wheels at the bottom of the device, easily causing the device to jolt and resulting in device damage. The device sweeps the stones and other sundries into the collection box 51, avoiding this problem. The cleaning mechanism 5 further includes: an inclined column 54, a push plate 55, and a third push column 56. The bottom end of the inclined column 54 is rotatably connected to the inner wall of the collection box 51 through a torsion spring. The push plate 55 is fixedly connected to the front surface of the inclined column 54. The upper end of the third push column 56 is fixedly connected to the lower surface of the first fixing plate 47. The lower output end of the dual-axis motor 8 is connected to the long rod of the brush disc 53 through a pulley group. The number of brush discs 53 is two, and the two brush discs 53 are connected through a pulley group. The lower surface of the push plate 55 contacts the inner wall of the collection box 51. The surface of the third push column 56 contacts the inner wall of the box body 1. The roller at the lower end of the third push column 56 contacts the inclined surface of the inclined column 54. When the first fixing plate 47 moves up and down, it drives the third push column 56 to move up and down. The third push column 56 moves up and down to drive the roller below the third push column 56 to move up and down on the inclined surface of the inclined column 54 located in the collection box 51. The third push column 56 drives the inclined column 54 to rotate. The inclined column 54 rotates to drive the push plate 55 to rotate. The device can dial the stones and other sundries into the collection box 51, effectively utilizing the space in the collection box 51 and further increasing the practicality of the device.

[0019] Working principle: When the dual-axis motor 8 rotates, it drives the first gear 41 to rotate. Since the first gear 41 meshes with the gear at the bottom of the gear set 42, the rotation of the first gear 41 drives the gear at the bottom of the gear set 42 to rotate. The rotation of the gear at the bottom of the gear set 42 drives the sector gear at the top inside the gear set 42 to rotate. Since the sector gear at the top of the gear set 42 meshes with the rack column 43, the rotation of the sector gear at the top of the gear set 42 drives the rack column 43 to move backward. When the sector gear at the top of the right gear set 42 has completely passed, the sector gear at the top of the left gear set 42 just meshes with the rack column 43, driving the rack column 43 to move forward, causing the rack column 43 to drive the brush plate to move back and forth on the upper surface of the box body 1, pushing the water on the upper surface of the box body 1 into the small holes opened on the upper surface of the box body 1 and flowing into the filter box 44 through the small holes. The activated carbon in the filter box 44 filters the water and then returns it to the water tank 2. At the same time, due to the long-term accumulation of waste water and dust, dust condensation may occur on the upper surface of the box body 1, making the device too dirty. The device can filter most of the suspended particles in the waste water through filtration, which usually contains a large amount of dust, particulate matter, etc., thus realizing the recycling of water resources. When the lifting plate 11 of the device moves up and down, it drives the first push column 48 to move up and down. Since the second push column 49 is limited by the limiting column 45, the up and down movement of the first push column 48 drives the second push column 49 and the first fixing plate 47 to move up and down respectively. The up and down movement of the second push column 49 drives the screw rod 410 to rotate, and the rotation of the screw rod 410 drives the stirring fan blade 46 to rotate. The device can stir the activated carbon in the filter box 44, increasing the contact area between the activated carbon and the waste water, so that the waste water is filtered more cleanly.

[0020] When the dual-axis motor 8 starts, the output shaft at the lower end drives the pulley group to rotate. The pulley group drives the brush disc 53 located below the second fixing plate 52 to rotate. The two brush discs 53 are connected by a pulley group. The rotation of the brush disc 53 sweeps the dirty water and sundries such as stones sprayed on the road surface into the collection box 51, enabling the device to collect substances such as stones at the construction site. Since there are many stones at the construction site, they may block the forward movement of the wheels at the bottom of the device, easily causing the device to jolt and resulting in device damage. The device sweeps the stones and other sundries into the collection box 51, avoiding this problem. When the first fixing plate 47 moves up and down, it drives the third push column 56 to move up and down. The third push column 56 drives the roller below the third push column 56 to move up and down on the inclined surface of the inclined column 54 located in the collection box 51. The third push column 56 drives the inclined column 54 to rotate, and the rotation of the inclined column 54 drives the push plate 55 to rotate. The device can dial the stones and other sundries into the collection box 51, effectively utilizing the space inside the collection box 51 and further increasing the practicality of the device.
