Description

Technical Field

[0001] This utility model relates to the field of environmental protection, and in particular to a dust suppression device for environmental protection. Background Technology

[0002] With the increasing density of urban residential communities, air pollution in these areas has become increasingly severe, especially in communities near highways, mining areas, and factories. The primary contributor to air pollution is inhalable particulate matter, particularly around construction sites where concentrations of PM2.5 and PM10 are significantly higher, seriously impacting the health of residents. Environmental protection is a pressing issue that permeates all aspects of life and production. For instance, construction sites generate substantial amounts of dust, necessitating the use of appropriate dust suppression devices for environmental protection. A search of Chinese patents revealed publication number CN215311138U, which discloses a dust suppression device for environmental protection. The device includes: a water tank with a partition horizontally inserted into the upper part of its inner cavity; an installation mechanism located at the bottom of the water tank; and a dust suppression mechanism within the inner cavity of the water tank. This dust suppression mechanism includes a connecting housing hinged to the top of the inner cavity, atomizing nozzles evenly installed on the top of the connecting housing, and a hydraulic rod installed on one side of the partition to lift the connecting housing. A water pump is located at the bottom of the inner cavity of the water tank, with its output end connected to a connecting pipe. The top of the connecting pipe passes through the partition and is connected to a flexible hose, the other end of which communicates with the inner cavity of the connecting housing. This dust suppression device for environmental protection is convenient to store and carry while ensuring effective dust suppression, and it can be easily fixed to a wall.

[0003] Existing dust suppression devices have a small dust suppression range. Generally, dust suppression devices suppress dust by spraying water from nozzles. However, the spray direction of the nozzles is fixed, resulting in a fixed spray area and a small spray range. If the spray range needs to be increased, a large number of nozzles need to be installed, which increases costs, reduces practicality, and makes it inconvenient to use. In order to solve the above problems, we propose a dust suppression device for environmental protection. Utility Model Content

[0004] The purpose of this invention is to provide a dust suppression device for environmental protection, which has the advantage of a large dust suppression range.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dust suppression device for environmental protection, comprising a base plate, a fixed shell bolted to the top of the base plate, a partition bolted to the inner wall of the fixed shell, a first rotating shaft and two second rotating shafts rotatably sleeved on the top of the partition, the first rotating shaft being located between the two second rotating shafts and rotatably sleeved with the inner wall of the fixed shell, a full-tooth gear fixedly sleeved on the surface of the first rotating shaft, a half-tooth gear fixedly sleeved on the top of the second rotating shaft, the half-tooth gear and the full-tooth gear being compatible, a height adjustment mechanism provided on the top of the first rotating shaft, an angle adjustment mechanism provided on the top of the height adjustment mechanism, a spraying mechanism provided on the surface of the angle adjustment mechanism, a synchronous pulley fixedly sleeved on the bottom of the second rotating shaft, a synchronous belt drivingly connecting the surfaces of the synchronous pulleys, a motor bolted to the top of the fixed shell, and the output end of the motor extending into the interior of the fixed shell and connected to the top of the left second rotating shaft via a coupling.

[0006] By adopting the above technical solution, the two second rotating shafts are rotated synchronously by the rotation of the motor. The rotation of the second rotating shafts drives the half-tooth gears to rotate, and the two half-tooth gears alternately mesh with the full-tooth gears. The full-tooth gears drive the first rotating shaft to rotate back and forth, thereby making the spray head rotate back and forth to spray. This method can achieve the purpose of a large spraying range, improve the efficiency of dust suppression, and reduce the cost of use.

[0008] By adopting the above technical solution, the lead screw is rotated by rotating the adjusting head. The rotation of the lead screw drives the slider to move, and the movement of the slider drives the tensioning wheel to move. The movement of the tensioning wheel tensions the synchronous belt, thereby adjusting the tension of the synchronous belt, ensuring the stability of the transmission, and facilitating its use.

[0010] By adopting the above technical solution, and by setting up a height adjustment mechanism, the spray head can be moved to the required height by loosening the first bolt, and the telescopic rod can be fixed by tightening the first bolt, thus adjusting the spray height.

[0011] The present invention is further configured such that: the angle adjustment mechanism includes a U-shaped frame, the bottom of the U-shaped frame is bolted to the top of the telescopic rod, a fixed shaft is fixedly sleeved between the inner walls of the U-shaped frame, a rotating ring is rotatably sleeved on the surface of the fixed shaft, an anti-slip toothed plate is slidably connected to the inner wall of the rotating ring, a second bolt is rotatably connected to the surface of the anti-slip toothed plate, and the second bolt is threadedly connected to the inner wall of the rotating ring; an anti-slip toothed ring is fixedly sleeved on the surface of the fixed shaft, and the anti-slip toothed ring meshes with the anti-slip toothed plate.

[0012] By adopting the above technical solution, by setting an angle adjustment mechanism, rotating the second bolt to disengage the anti-slip toothed plate from the anti-slip toothed ring, adjusting the spray head to the required angle, and tightening the second bolt to engage the anti-slip toothed plate with the anti-slip toothed ring and fix them, the spray angle can be adjusted.

[0014] By adopting the above technical solution and setting up a spraying mechanism, spraying is facilitated.

[0015] The present invention is further configured such that one end of the lead screw extends to the outside of the fixed shell and is bolted to an adjusting head.

[0016] By adopting the above technical solution, the lead screw can be easily rotated by setting an adjustment head.

[0017] The present invention is further configured such that: the bottom of the base plate is bolted with multiple casters.

[0018] The above technical solution, by incorporating casters, facilitates movement.

[0019] The present invention is further configured such that a push handle is bolted to the top of the base plate.

[0020] The above technical solution, by setting up a push handle, facilitates movement.

[0021] In summary, this utility model has the following beneficial effects: 1. This utility model uses a motor to rotate two second rotating shafts synchronously. The rotation of the second rotating shafts drives the half-tooth gears to rotate, so that the two half-tooth gears alternately mesh with the full-tooth gears. The full-tooth gears drive the first rotating shaft to rotate back and forth, thereby causing the spray head to rotate back and forth to spray. This method can achieve a large spraying range, improve dust suppression efficiency, and reduce operating costs. 2. This utility model uses the rotating adjustment head to rotate the lead screw, which in turn drives the slider to move. The slider then drives the tensioning wheel to move, which in turn tensions the timing belt. This allows for adjustment of the timing belt tension, ensuring transmission stability and making it convenient to use. Attached Figure Description

A motor 13 is bolted to the top of the fixed housing 2, and the output end of the motor 13 extends into the interior of the fixed housing 2 and is connected to the top of the left second rotating shaft 5 through a coupling. The rotation of the motor 13 causes the two second rotating shafts 5 to rotate synchronously. The rotation of the second rotating shafts 5 drives the half-tooth gear 7 to rotate, so that the two half-tooth gears 7 alternately mesh with the full-tooth gear 6, causing the full-tooth gear 6 to drive the first rotating shaft 4 to rotate back and forth. This causes the spray head 26 to rotate back and forth and spray, which can achieve the purpose of a large spraying range, improve the dust suppression efficiency, and reduce the operating cost.

[0026] refer to Figure 1 The height adjustment mechanism 8 includes a telescopic rod 18, which is slidably sleeved with the inner wall of the first rotating shaft 4.

By setting the height adjustment mechanism 8, the spray head 26 can be moved to the required height by loosening the first bolt 19 and by tightening the first bolt 19 to fix the telescopic rod 18, thus adjusting the spray height.

[0027] refer to Figure 4 The angle adjustment mechanism 9 includes a U-shaped frame 20. The bottom of the U-shaped frame 20 is bolted to the top of the telescopic rod 18. A fixed shaft 21 is fixedly sleeved between the inner walls of the U-shaped frame 20. A rotating ring 22 is rotatably sleeved on the surface of the fixed shaft 21.

An anti-slip toothed ring 25 is fixedly sleeved on the surface of the fixed shaft 21, and the anti-slip toothed ring 25 meshes with the anti-slip toothed plate 23. By setting the angle adjustment mechanism 9, rotating the second bolt 24 disengages the anti-slip toothed plate 23 from the anti-slip toothed ring 25, adjusts the spray head 26 to the required angle, and tightens the second bolt 24 to engage the anti-slip toothed plate 23 with the anti-slip toothed ring 25, fixing them in place, thereby enabling the adjustment of the spray angle.

[0028] refer to Figure 1The spraying mechanism 10 includes a spray head 26, which is bolted to the surface of the rotating ring 22.

This allows for adjustment of the tension of the synchronous belt 12, ensuring transmission stability and ease of use.

[0030] Referring to the figure, one end of the lead screw 16 extends to the outside of the fixed housing 2 and is bolted to an adjusting head 30. By setting the adjusting head 30, it is easy to rotate the lead screw 16.

[0031] Referring to the figure, the bottom of the base plate 1 is bolted with multiple casters 31, which facilitate movement.

[0032] Referring to Figures 1 and 2, a push handle 32 is bolted to the top of the base plate 1, which facilitates movement.

[0033] Brief description of operation: Water pump 28 delivers water from water tank 29 to connecting pipe 27, and then from connecting pipe 27 into spray head 26 for dust suppression. Motor 13 rotates, driving second shaft 5 to rotate. Second shaft 5 rotates, driving synchronous pulley 11 to rotate. Synchronous pulley 11 rotates, driving synchronous belt 12 to rotate. Synchronous belt 12 rotates, driving another synchronous pulley 11 to rotate. The other synchronous pulley 11 rotates, driving another second shaft 5 to rotate. This causes the two second shafts 5 to drive half-gear 7 to rotate synchronously, thus causing the two half-gear 7 to alternately mesh with full-gear 6, causing full-gear 6 to reciprocate. The reciprocating rotation of full-gear 6 drives... The first rotating shaft 4 rotates, causing the spray head 26 to reciprocate and spray to suppress dust, thus achieving a large dust suppression range. The adjusting head 30 rotates the lead screw 16, which in turn moves the slider 15. The slider 15 then moves the tension wheel 17, which in turn tensions the synchronous belt 12, thus allowing adjustment of the tension of the synchronous belt 12. The second bolt 24 is rotated to disengage the anti-slip toothed plate 23 from the anti-slip toothed ring 25, allowing the spray head 26 to be adjusted to the required angle. The second bolt 24 is then tightened to engage the anti-slip toothed plate 23 with the anti-slip toothed ring 25, fixing them in place, thus allowing adjustment of the spray angle.
