Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to an automatic dust suppression device for earthwork construction. Background Technology

[0002] Earthwork engineering is one of the major engineering processes in building construction, encompassing all aspects of earthwork (excavation, filling, transportation, drainage, and dewatering). In civil engineering, earthwork includes: site leveling, roadbed excavation, civil defense project excavation, ground filling, roadbed construction, and foundation pit backfilling.

[0003] During construction, dump trucks are needed to transport the excavated soil. Due to the high dust levels and poor environment at the construction site, the dump trucks accumulate a lot of dust and mud. To prevent dust from being stirred up when the dump trucks drive on the road, they need to be washed with water guns to remove the mud and dust before leaving the site. After washing, a lot of water remains on the truck body. When the dump trucks drive on the road, the water drips directly onto the road, causing the road surface to become slippery and potentially affecting traffic safety. In addition, a large amount of water cannot be recycled, resulting in a waste of water resources. Summary of the Invention

[0014] 1. This invention uses a dust-reducing mechanism to wash away dust and mud from the surface of dump trucks inside the dust-reducing chamber. As the dump truck continues to travel through the dust-reducing mechanism and moves to the water-absorbing mechanism, the water-absorbing mechanisms on both sides absorb the water stains on the left and right sides of the dump truck.

Detailed Implementation

[0025] Please see Figures 1-7 This invention provides a technical solution: an automatic dust suppression device for earthwork construction, comprising a dust suppression chamber 1, with dehydration chambers 2 symmetrically fixedly connected to the left and right sides of the dust suppression chamber 1; a first water storage chamber 3 and a second water storage chamber 4 are respectively provided at the bottom of the dust suppression chamber 1 and the dehydration chamber 2; a support plate 5 is provided on the upper side of the first water storage chamber 3, and the support plate 5 is fixedly connected to the dust suppression chamber 1; inclined plates 6 are symmetrically fixedly connected to the front and rear sides of the dust suppression chamber 1; dust suppression mechanisms are symmetrically provided on the left and right sides inside the dust suppression chamber 1, which are used to clean the dust and mud from the surface of the dump truck located in the dust suppression chamber 1; water suction mechanisms are symmetrically provided on the left and right sides in front of the dust suppression chamber 1, which are used to absorb most of the water stains on the surface of the dump truck after dust suppression by the dust suppression mechanism; a dehydration mechanism is provided in the dehydration chamber 2, which is used to separate the water absorbed by the water suction mechanism so that the water suction mechanism can continuously absorb water.

[0026] During construction, earthwork is one of the main engineering projects, including all earthwork (rock) excavation, filling, transportation, drainage, and dewatering. In civil engineering, earthwork includes: site leveling, roadbed excavation, civil defense excavation, ground filling, roadbed construction, and foundation pit backfilling. During construction, dump trucks are needed to transport the excavated soil. Due to the high dust levels and poor environment at construction sites, dump trucks accumulate a lot of dust and mud. To prevent dust from being generated when driving on the road, dump trucks need to be washed with water guns to remove the mud and dust before leaving the site. After washing, a large amount of water remains on the truck body. When the truck is driving on the road, this water drips directly onto the road, causing slippery surfaces and potentially affecting traffic safety. Furthermore, the large amount of water cannot be recovered, resulting in water waste. When the dump truck needs to remove the soil, it travels through the inclined plate 6 at the rear to enter the dust suppression chamber 1, and then the left side of the dust suppression chamber 1 is activated. The dust suppression mechanisms on both sides operate, washing away dust and mud from the surface of the dump truck. As the dump truck continues to travel through the dust suppression mechanisms and moves to the water suction mechanism, the water suction mechanisms on both sides absorb the water stains on the left and right sides of the dump truck. After the dump truck passes through the water suction mechanism, most of the water stains on its surface are absorbed, and finally the dump truck leaves the dust suppression chamber 1 through the inclined plate 6 at the front. After the water suction mechanism has finished absorbing the water, the dehydration mechanism is activated to separate the water absorbed by the water suction mechanism. The separated water eventually falls into the second water storage chamber 4. This device has a simple structure and is easy to use. It can automatically wash the dump truck, achieving the effect of dust suppression. At the same time, after washing the dump truck, it can absorb the water stains on its surface, effectively avoiding excessive waste of water resources and preventing large amounts of water from dripping onto the road and causing slippery road surfaces.

[0027] As a further embodiment of the present invention, the dust suppression mechanism includes a water pump 7, which is located inside the second water storage chamber 4 and is fixedly connected to the second water storage chamber 4; multiple nozzles 8 are evenly fixedly connected to the inner walls of the left and right sides of the dust suppression chamber 1; a water pipe 9 is fixedly connected to the drainage outlet of the water pump 7, and the other end of the water pipe 9 is connected to the multiple nozzles 8; during operation, when the dump truck drives into the dust suppression chamber 1, the water pumps 7 on the left and right sides are started, and the water pumps 7 can draw water from the second water storage chamber 4 on the left and right sides into the water pipe 9. The water in the water pipe 9 is finally sprayed onto the surface of the dump truck through the nozzles 8, and the sprayed water can wash away the dust and mud on the surface of the dump truck.

[0028] As a further embodiment of the present invention, the water absorption mechanism includes a fixed frame 10, which is located at the center of the dehydration chamber 2 and is fixedly connected to the second water storage chamber 4. A rotating frame 11 is rotatably connected to the surface of the fixed frame 10, and three connecting frames 12 are slidably connected to the surface of the rotating frame 11. The three connecting frames 12 are arranged in a circular array on the surface of the rotating frame 11. A first spring 13 is provided between the connecting frame 12 and the rotating frame 11. One end of the first spring 13 is fixedly connected to the rotating frame 11 and the other end is fixedly connected to the connecting frame 12. A sponge is rotatably connected inside the connecting frame 12. Sponge rod 14; the rightmost sponge rod 14 on the left and the leftmost sponge rod 14 on the right are partially located inside the dust suppression chamber 1; during operation, when the dump truck continues to move forward in the dust suppression chamber 1, the dump truck will come into contact with the sponge rods 14 on the left and right sides. When the sponge rod 14 comes into contact with the dump truck, it will absorb the water stains on its surface. As the dump truck continues to move forward, the sponge rod 14 will rotate in coordination with the dump truck to absorb water stains; after the sponge rod 14 in the absorption position has absorbed the water stains, the dry sponge rod 14 can be adjusted to the absorption position to continue absorbing water stains by driving the rotating frame 11 to rotate.

[0029] As a further embodiment of the present invention, the dehydration mechanism includes a sliding frame 15, which is slidably connected to a fixed frame 10, and a second spring 16 is fixedly connected to the upper surface of the sliding frame 15, with the upper end of the second spring 16 fixedly connected to the fixed frame 10; a first motor 17 is fixedly connected to the upper side of two sponge rods 14 located away from the dust settling chamber 1 on the surface of the sliding frame 15, and a drive disk 18 is fixedly connected to the bottom end of the output shaft of the first motor 17, with the bottom end of the drive disk 18 fitting against the rotating shaft of the sponge rod 14; a switching mechanism is provided above the dust settling chamber 1, which is used to switch the sponge rod 14 located inside the dust settling chamber 1 after it has absorbed water. 14. Switch to the dehydration position and switch the dehydrated sponge rod 14 to the water absorption position. During operation, when the drive rotating frame 11 rotates, the sponge rod 14 that has absorbed water can be moved away and the dry sponge rod 14 can be adjusted to the absorption position. At this time, the sponge rod 14 that has absorbed water is exactly at the bottom position of the drive disc 18 in front. Under the action of the second spring 16, the sliding frame 15 will drive the drive rod 27 to fit with the sponge rod 14. At this time, the first motor 17 is started. The first motor 17 will drive the sponge rod 14 to rotate through the drive disc 18. When the sponge rod 14 rotates, the centrifugal force can throw out the water absorbed inside it.

[0030] As a further embodiment of the present invention, the switching mechanism includes a second motor 19, which is fixedly connected to the dust settling chamber 1, and a threaded rod 20 is fixedly connected to the rear end of the output shaft of the second motor 19. A sliding plate 21 is threadedly fitted onto the surface of the threaded rod 20. The sliding plate 21 is slidably connected to the dust settling chamber 1, and a first connecting rod 22 is symmetrically rotatably connected to the left and right sides of the sliding plate 21. A torsion spring 23 is fixedly connected to the surface of the first connecting rod 22 at the connection point with the sliding plate 21, and the other end of the torsion spring 23 is fixedly connected to the sliding plate 21. A limiting ring 24 is provided on the upper side of the dehydration chamber 2. The limiting ring 24 is circular and fixedly connected to the dehydration chamber 2. An opening is provided on the side of the limiting ring 24 near the dust settling chamber 1. A first drive is fixedly connected to the upper surface of the connecting frame 12. Moving block 25, the first driving block 25 is in contact with the limiting ring 24 and is close to the dust chamber 1. The first driving block 25 and the opening of the limiting ring 24 are fitted with a clearance. The front end of the first connecting rod 22 is slidably connected to the second driving block 26. The outer surface of the second driving block 26 is inclined and the inner surface is vertical. The first driving block 25 is located in the opening of the limiting ring 24 and its inner surface is in contact with the first driving block 25. During operation, when the sponge rod 14 needs to be replaced, the second motor 19 can be started to drive the threaded rod 20 to rotate. When the threaded rod 20 rotates, it will drive the sliding plate 21 to slide forward. When the sliding plate 21 slides forward, it can drive the first driving block located in the opening of the limiting ring 24 under the action of the first connecting rod 22 and the second driving block 26 on its surface. 25 moves away from the dust settling chamber 1. At this time, the first driving block 25 will drive the connecting frame 12 connected to it to move. When the first driving block 25 moves to the position outside the opening of the limiting ring 24, the first connecting rod 22 will push the first driving block 25 to move along the trajectory of the limiting ring 24 through the second driving block 26. When the first driving block 25 moves, it drives the rotating frame 11 to rotate through the connecting frame 12. When the rotating frame 11 rotates, it will drive the other two sponge rods 14 to move synchronously. When the next first driving block 25 moves to the opening position of the limiting ring 24, under the action of the first spring 13, the next first driving block 25 will directly enter the opening of the limiting ring 24, and the dry seawater corresponding to the next first driving block 25 will be directly connected to the limiting ring 24. The cotton swab 14 will move directly to the water absorption position, and the water-absorbed cotton swab 14 is exactly at the bottom of the drive plate 18 in the front position. At this time, the second motor 19 can be controlled to drive the sliding plate 21 to reset backward. When the sliding plate 21 moves backward, it drives the second drive block 26 to move backward through the first connecting rod 22. After the second drive block 26 disengages from the first drive block 25, the first connecting rod 22 rotates and resets under the action of the torsion spring 23. When the sliding plate 21 slides to the rearmost position, the second drive block 26 will be squeezed upward when it moves to the position where it contacts the first drive block 25 located in the opening of the limiting ring 24. After the second drive block 26 passes through the first drive block 25, it will fall down under its own weight.

[0031] As a further embodiment of the present invention, a sliding block 36 is slidably connected to the surface of the sliding frame 15 at the position of the first driving block 25 near the front side. A driving rod 27 is slidably connected to the surface of the sliding block 36 and passes through the sliding block 36. The driving rod 27 is in contact with the first driving block 25 at the front side, and a third spring 28 is fixedly connected to the surface of the sliding block 36. The other end of the third spring 28 is fixedly connected to the sliding frame 15. A connecting frame 29 is fixedly connected to the surface of the driving rod 27. The connecting frame 29 is slidably connected to the sliding frame 15, and a locking block 30 is fixedly connected to the surface of the connecting frame 29. A slot 31 is formed on the surface of the fixed frame 10 at the position above the locking block 30. A second connecting rod 32 is rotatably connected to the surface of the sliding frame 15, located near the dust settling chamber 1. An arc-shaped plate 33 is rotatably connected to the other end of the second connecting rod 32. The arc-shaped plate 33 is in contact with the inner wall of the limiting ring 24 and is slidably connected to the fixed frame 10. During operation, when the sliding plate 21 moves forward, it drives the first driving block 25, located within the opening of the limiting ring 24, to move away from the dust settling chamber 1 via the first connecting rod 22 and the second driving block 26. This movement of the first driving block 25 pushes the arc-shaped plate 33, which in turn drives the sliding frame 15 upwards via the second connecting rod 32. As the sliding frame 15 slides upwards, it drives the surface of its sliding frame 15... The locking block 30 and the drive plate 18 move upwards; when the second drive block 26 drives the first drive block 25 to a position where it disengages from the opening of the limiting ring 24, the locking block 30 on the surface of the sliding frame 15 moves to the same height as the slot 31; as the sliding plate 21 continues to slide, the three first drive blocks 25 begin to move along the surface of the limiting ring 24. The arc plate 33 remains stationary under the action of the first drive blocks 25, while the first drive block 25 at the front position will disengage directly from the drive rod 27 when it moves. At this time, the drive rod 27 drives the sliding frame 15 to move under the action of the third spring 28. When the sliding frame 15 moves, it will drive the locking block 30 to directly engage with the slot 31. Inside; when the second driving block 26 drives the first driving block 25 to the position where it is disengaged from the arc plate 33, the sliding frame 15 will not reset under the action of the locking block 30 and the locking groove 31, and the arc plate 33 will remain stationary; when the next first driving block 25 moves to the opening position of the limiting ring 24, the second driving block 26 pushes the first driving block 25 to the position of the squeezing driving rod 27. After the driving rod 27 is squeezed, it will drive the locking block 30 to disengage from the locking groove 31 through the sliding frame 15. After the locking block 30 disengages from the locking groove 31, the sliding frame 15 moves downward to reset under the action of the third spring 28, and the driving disk 18 will fit against the rotating shaft of the sponge rod 14 at its bottom.

[0032] As a further embodiment of the present invention, a plurality of permeable holes 34 are evenly provided on the surface of the support plate 5; filters 35 are symmetrically fixedly connected to the left and right sides of the first water storage chamber 3, and the other ends of the filters 35 on the left and right sides are respectively connected to the second water storage chambers 4 on the left and right sides; during operation, when the nozzle 8 sprays water to wash the dump truck, the washed mud water will flow directly into the first water storage chamber 3 through the permeable holes 34; when the water pump draws water from the second water storage chamber 4, the water in the first water storage chamber 3 will flow into the second water storage chamber 4 through the filters 35, thereby effectively saving water resources.
