Description

Technical Field

[0001] This utility model relates to the field of dust suppression technology in earthwork engineering, specifically a dust suppression device for earthwork engineering construction. Background Technology

[0002] Earthwork engineering is a general term for earthwork and stonework, usually measured in cubic meters. It covers all construction processes such as excavation, filling, transportation, drainage, and dewatering of earth (stone). When carrying out earthwork engineering, a large amount of dust will be generated on site. Dust can cause harm to workers and the environment, so dust suppression treatment is necessary.

[0003] Existing patent CN218130762U discloses a high-efficiency dust suppression device for earthwork engineering. The device includes a water tank housing a water pump, with a fixed pipe connected to the pump's outlet. A flexible hose is connected to one end of the fixed pipe, and a spray pipe is connected to the other end. Spray nozzles are symmetrically arranged on one side of the spray pipe. A mounting plate is screwed to one side of the water tank, and a movable plate is located on one side of the mounting plate. Limit rings are symmetrically arranged on one side of the movable plate. A connecting plate is located on the upper surface of the trolley on one side of the water tank, and a storage box is installed on one side of the connecting plate. The spray pipe is secured by engaging the limit rings. Under the operation of a cylinder, the sliding plate connected to the movable plate can move, allowing the spray pipe to be used in different positions and effectively suppressing dust generated during earthwork engineering, thus protecting the environment.

[0004] Based on the search of the aforementioned patents and in conjunction with existing dust suppression devices, it was found that although the aforementioned dust suppression devices can spray dust at the construction site, the spraying range of the nozzle is limited, resulting in a lower dust suppression effect. At the same time, their fixed position makes it inconvenient for workers to remove them for handheld spraying, thus reducing their practicality. Utility Model Content

[0005] The purpose of this utility model is to provide a dust suppression device for earthwork construction, in order to solve the problems mentioned in the background art. Although the existing dust suppression devices can spray dust at the construction site, the spraying range of the nozzle is limited, resulting in a lower dust suppression effect. At the same time, the fixed position makes it inconvenient for workers to remove and use for hand-held spraying, thus reducing practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust suppression device for earthwork construction, comprising a movable base and a water supply pipe, wherein a water tank is fixedly connected to the top of the movable base, an adjustment component is provided on the top of the water tank, and a pick-and-place component is provided on the top of the water tank;

[0007] The adjusting component includes a first rotating shaft connected to the top of the water tank, a first actuating plate fixedly connected to the outside of the first rotating shaft, a rotating plate fixedly connected to the outside of the first rotating shaft, a vertical plate fixedly connected to the top of the water tank, a first spring disposed between the vertical plate and the rotating plate, a second rotating shaft connected to the top of the water tank, a motor fixedly connected to the top of the second rotating shaft, and a second actuating plate fixedly connected to the outside of the second rotating shaft. Both the first rotating shaft and the second rotating shaft are rotatably connected to the water tank, and the two ends of the first spring are fixedly connected to the vertical plate and the rotating plate, respectively.

[0008] Preferably, the picking and placing component includes a lifting seat, a fixing plate fixedly connected to both sides of the top of the lifting seat, a through opening on one side of the fixing plate, a guide rod disposed in the through opening, an arc-shaped clamp fixedly connected to one end of the guide rod, and a second spring sleeved on the outside of the guide rod. The two ends of the second spring are fixedly connected to the arc-shaped clamp and the fixing plate, respectively, and the guide rod is slidably connected to the through opening.

[0009] Preferably, a water pump is fixedly connected to one side of the water tank, a water pump pipe is fixedly connected to one side of the water pump, a hose is fixedly connected to the other side of the water pump, a spray pipe is fixedly connected to one side of the water supply pipe, multiple nozzles are fixedly connected to one side of the spray pipe, the water pump pipe is connected to the water tank, and the hose is connected to the water supply pipe.

[0010] Preferably, a sliding rod is fixedly connected to one side of the rotating plate, and a sliding opening is provided on one side of the vertical plate, with the sliding rod slidably connected to the sliding opening.

[0011] Preferably, a fixed frame is fixedly connected to the top of the first rotating shaft, and a cylinder is installed inside the fixed frame. The output end of the cylinder is fixedly connected to the lifting seat.

[0012] Preferably, guide grooves are provided on both sides of the top of the lifting seat, and guide blocks are slidably connected in the guide grooves. The guide blocks are fixedly connected to the arc-shaped clamping plate.

[0013] Preferably, a water filling hopper is fixedly connected to one side of the top of the water tank, and the water filling hopper is funnel-shaped.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting up a movable base, water supply pipe, water tank, and adjusting components, the motor can drive the second rotating shaft to rotate, which in turn drives the second actuating plate to rotate. The rotation of the second actuating plate can contact the first actuating plate and push it to rotate, which in turn drives the first rotating shaft to rotate, which in turn drives the rotating plate to rotate, which in turn squeezes the first spring to deform. When the second actuating plate disengages from the first actuating plate, the first spring returns to its original position, which can drive the first rotating shaft to return to its original position, which can make the nozzle swing repeatedly, thereby increasing the dust suppression spray range and greatly improving the practicality of the device.

[0016] 2. With the addition of a pick-and-place component, pulling the guide rod can move the arc-shaped clamping plate, which in turn causes the second spring to deform. The water pipe can be placed between the two arc-shaped clamping plates. The thrust generated by the deformation of the second spring can push the arc-shaped clamping plate to fix the water pipe. At the same time, the water pipe can be removed from the two arc-shaped clamping plates, making it easier for workers to hold the water pipe and spray dust suppression in some dead corners, which can further increase the spraying range and thus further improve its practicality.

A water tank 12 is fixedly connected to the top of the movable base 1. An adjusting component and a pick-and-place component are provided on the top of the water tank 12. The adjusting component includes a first rotating shaft 21 connected to the top of the water tank 12, a first actuating plate 22 fixedly connected to the outside of the first rotating shaft 21, a rotating plate 23 fixedly connected to the outside of the first rotating shaft 21, a vertical plate 24 fixedly connected to the top of the water tank 12, a first spring 25 disposed between the vertical plate 24 and the rotating plate 23, a second rotating shaft 26 connected to the top of the water tank 12, and a motor fixedly connected to the top of the second rotating shaft 26. The motor 27 and the second actuating plate 28 are fixedly connected to the outside of the second rotating shaft 26. The first rotating shaft 21 and the second rotating shaft 26 are both rotatably connected to the water tank 12. The two ends of the first spring 25 are fixedly connected to the vertical plate 24 and the rotating plate 23, respectively. The motor 27 can drive the second rotating shaft 26 and the second actuating plate 28 to rotate, which in turn can drive the first actuating plate 22 and the first rotating shaft 21 to rotate, which in turn can drive the rotating plate 23 to rotate, which in turn can drive the first spring 25 to deform. The first spring 25 returning to its original position can drive the first rotating shaft 21 to return to its original position, which in turn can cause the water pipe 11 to swing repeatedly, thereby increasing the spraying range. A water pump 41 is fixedly connected to one side of the water tank 12. A water pump 41 is fixedly connected to a water suction pipe 42 on one side and a hose 43 on the other side. A water delivery pipe 11 is fixedly connected to a spray pipe 44 on one side, and multiple nozzles 45 are fixedly connected to one side of the spray pipe 44. The water suction pipe 42 is connected to a water tank 12, and the hose 43 is connected to the water delivery pipe 11. When the water pump 41 works, it can draw water from the water tank 12 through the water suction pipe 42, and then the water enters the water delivery pipe 11 and the spray pipe 44 through the hose 43, and then be sprayed out through the nozzles 45 to suppress dust. A sliding rod 51 is fixedly connected to one side of the rotating plate 23, and a sliding port 52 is opened on one side of the vertical plate 24. The sliding rod 51 is slidably connected to the sliding port 52. The first spring 2... Five are set on the outside of the sliding rod 51. The rotation of the rotating plate 23 can drive the sliding rod 51 to move. The sliding rod 51 can support the first spring 25 and prevent the first spring 25 from tilting when it deforms. The top of the first rotating shaft 21 is fixedly connected to the fixed frame 61. The fixed frame 61 is installed in the fixed frame 61. The output end of the cylinder 62 is fixedly connected to the lifting seat 31. The operation of the cylinder 62 can push the lifting seat 31 to move vertically, which can facilitate the vertical movement of the nozzle 45 and make it easy to change the working height of the nozzle 45. A water filling funnel 81 is fixedly connected to one side of the top of the water tank 12. The water filling funnel 81 is funnel-shaped and can facilitate the addition of water into the water tank 12.

[0029] Please see Figure 1 , Figure 2 , Figure 5 as well as Figure 6The loading and unloading components include a lifting base 31, fixed plates 32 fixedly connected to both sides of the top of the lifting base 31, an opening 33 on one side of the fixed plate 32, a guide rod 34 disposed in the opening 33, an arc-shaped clamping plate 35 fixedly connected to one end of the guide rod 34, and a second spring 36 sleeved on the outside of the guide rod 34. The two ends of the second spring 36 are fixedly connected to the arc-shaped clamping plate 35 and the fixed plate 32, respectively. The guide rod 34 is slidably connected to the opening 33. By pushing the arc-shaped clamping plate 35, the guide rod 34 can be moved, and at the same time, the second spring 36 can be squeezed to deform it. The water pipe 11 can be placed in two arc-shaped clamping plates. Between the clamping plates 35, the thrust generated by the deformation of the second spring 36 can push the two arc-shaped clamping plates 35 to fix the water pipe 11. At the same time, it is easy to remove the water pipe 11 from the lifting seat 31, so that the water pipe 11 can be held by hand to spray dust in some dead corners. The top two sides of the lifting seat 31 are respectively provided with guide grooves 71, and guide blocks 72 are slidably connected in the guide grooves 71. The guide blocks 72 are fixedly connected to the arc-shaped clamping plates 35. The arc-shaped clamping plates 35 can drive the guide blocks 72 to move. The guide blocks 72 can prevent the arc-shaped clamping plates 35 from tilting and ensure the stable movement of the arc-shaped clamping plates 35.

[0030] Working principle: During operation, the water pipe 11 is first fixed, and the two arc-shaped clamps 35 are pushed to move in opposite directions. The movement of the arc-shaped clamps 35 causes the second spring 36 to deform. Then, the water pipe 11 is placed between the two arc-shaped clamps 35. The thrust generated by the deformation of the second spring 36 pushes the two arc-shaped clamps 35 to fix the water pipe 11. The water pump 41 is started, and the water pump 41 draws water from the water tank 12 through the water pipe 42, then discharges it into the hose 43, and then into the water pipe 11 and the spray pipe 44. Finally, it is sprayed out through the nozzle 45 for dust suppression. The motor 27 is started, which drives the second rotating shaft 26 and the second actuating plate 28 to rotate. The rotation of the second actuating plate 28 allows it to contact the first actuating plate 22 and push... When the device is rotated, the first actuating plate 22 drives the first rotating shaft 21 and the rotating plate 23 to rotate. The rotation of the rotating plate 23 can cause the first spring 25 to deform. When the second actuating plate 28 moves away from the first actuating plate 22, the first spring 25 resets and drives the first rotating shaft 21 to reset. This repeated motion can cause the nozzle 45 to swing repeatedly, thereby increasing the spraying range. The cylinder 62 can be activated to push the lifting seat 31 to move vertically, thereby adjusting the spraying height of the nozzle 45. When manual spraying is required, the arc-shaped clamp 35 can be pushed again, and then the water pipe 11 can be removed. The worker can then hold the water pipe 11 and spray some dead corners. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
