The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific uses.

[0031] Example 1: Please refer to Figure 1 , Figure 7 , Figure 8-Figure 10 The present invention provides a technical solution: a dust suppression device for construction engineering, specifically comprising:

[0032] A machine base 1, a bottom wheel 2 is movably mounted at the bottom of the machine base 1, and angle adjustment devices 3 are movably mounted on both sides of the top of the machine base 1, and the angle adjustment devices 3 are used to adjust the angle of the dust reduction device, so as to facilitate the degree of change of the angle and improve the dust reduction effect;

[0033] The angle adjustment device 3 includes a main beam 31, a vertical rod 32 is movably installed in the inner cavity of the main beam 31, a swing piece 33 is fixedly connected to the outer surface of the vertical rod 32, and an arc bar 34 is fixedly installed in the middle of the left bottom of the swing piece 33. The arc bar 34 moves toward the main beam 31, and the arc bar 34 slides along the bottom groove of the sleeve frame 44. When the arc bar 34 moves, it squeezes the spring part 35 and moves. The spring on the outer surface of the spring part 35 gradually buffers itself, and the spring part 35 squeezes the swing piece 3 3, a spring member 35 is movably mounted on the inner surface of the arc strip 34, a chuck 36 is movably mounted on the middle part of the right side of the throw-off member 33, the spring member 35 is connected to the chuck 36 through the throw-off member 33, the throw-off member 33 is located between the chuck 36 and the spring member 35, and a notch corresponding to the spring member 35 is movably opened at the inner cavity of the throw-off member 33, the spring member 35 is composed of a spring and a rod, the arc strip 34 itself has a certain curvature, and the spring member 35 is connected to the sleeve frame member 44 through the arc strip 34.

[0034] When the height needs to be adjusted, the sleeve frame 44 moves downward, the sleeve frame 44 squeezes the arc strip 34 to move, the arc strip 34 moves toward the main beam 31, and the arc strip 34 slides along the bottom groove of the sleeve frame 44. When the arc strip 34 moves, it squeezes the spring member 35 to move. The spring on the outer surface of the spring member 35 gradually buffers itself, and the spring member 35 squeezes the fling member 33 to move. The fling member 33 gradually folds over, and the fling member 33 forms an upward tilt. The spring member 35 is connected to the chuck 36 through the fling member 33. The fling member 33 is composed of a plate and an arc strip. The arc bar 34 is composed of two parts. The spring member 35 squeezes the upper plate of the swing member 33 to move. The bottom of the upper plate of the swing member 33 moves to the side away from the main beam 31, and pushes the arc bar 34 back to the outermost side of the frame member 44 again, and then moves clockwise through the bottom of 33 to ensure the balance of the frame member 44 when it is lifted or lowered. The chuck 36 prevents the swing member 33 from loosening and reinforces it, thereby ensuring that the equipment has the force adjusted according to the height, and automatically twists the support collection angle, thereby improving the efficiency of dust reduction and facilitating the purpose of environmental treatment.

[0035] Example 2: Please refer to Figure 1 , Figure 2 , Figure 5-Figure 8 , the present invention provides a technical solution: a leveling device 4 is movably installed on the top of the angle adjustment device 3, and the leveling device 4 is used to adjust the height position of the dust reduction treatment;

[0036] The leveling device 4 includes an upper plate 41, a side piece 42 is movably mounted on the front of the bottom of the upper plate 41, and the side piece 42 is moved by an external force to cause the side piece 42 to slide up or down along the side wall of the slide plate 43, a sleeve frame 44 is movably mounted on the left side of the side piece 42, a slide plate 43 is slidably mounted on the side edge of the bottom of the side piece 42, a filter layer 45 is movably mounted in the middle of the inner cavity of the sleeve frame 44, and the filter layer 45 screens the particle size of the dust, and the particle dust seeps out from the bottom of the filter layer 45, a part of which is retained in the upper layer of the filter layer 45, and the other part falls to the bottom of the sleeve frame 44 after being screened by the filter layer 45, and a cleaning device 46 is movably mounted on the right side of the upper surface of the filter layer 45;

[0037] The cleaning device 46 also includes an inclined plate 461, and a vertical bar 462 is movably installed on the left side of the inclined plate 461. The vertical bar 462 gradually changes from a loose state to a tightened state. The vertical bar 462 drags the curved bar 463 to move, and the comb bar 464 moves with the curved bar 463. The comb bar 464 gradually scrapes the dust on the upper part of the filter layer 45. The curved bar 463 is movably installed on the inner wall of the vertical bar 462. The comb bar 464 is fixedly connected to the inner surface of the curved bar 463. The comb bar 464 gradually scrapes the dust on the upper part of the filter layer 45. A support seat 465 is fixedly installed in the middle of the bottom of the inclined plate 461.

[0038] The other end of the vertical bar 462 is movably mounted on the slide plate 43 through the inner cavity of the inclined plate 461 and the support seat 465. A groove corresponding to the vertical bar 462 is opened in the middle of the support seat 465. The vertical bar 462 gradually changes from a relaxed state to a tightened state. The vertical bar 462 drags the curved bar 463 to move, and the comb bar 464 moves with the curved bar 463. The vertical bar 462 is made of rubber. The angle between the curved bar 463 and the vertical bar 462 is less than ninety degrees. A supporting accessory is arranged between the side member 42 and the sleeve frame member 44, and the supporting accessories between the sleeve frame member 44 and the side member 42 are arranged in a "V"-shaped structure. The supporting accessories are located between the side member 42 and the sleeve frame member 44. The side member 42 is connected to the sleeve frame member 44 through the supporting accessories, and vibrates through the coordinated action of the lifting and lowering displacement of the side member 42 and the sleeve frame member 44. The supporting accessories are a plate in the middle of the bottom of the sleeve frame member 44 close to the main beam 31, and the filter layer 45 itself is provided with evenly distributed grooves.

[0039] When dust reduction treatment is required, the side piece 42 slides along the side wall of the slide plate 43, and a supporting accessory is provided between the side piece 42 and the frame piece 44. When the side piece 42 slides up or down, the side piece 42 links with the supporting accessory to vibrate, and the frame piece 44 is jolted when it moves up or down to cause the dust inside to move. The filter layer 45 comes into contact with the dust, and the filter layer 45 itself is provided with a slot, and the filter layer 45 screens the particle size of the dust. Particulate dust seeps out from the bottom of the filter layer 45, a part of which is retained in the upper layer of the filter layer 45, and the other part falls to the bottom of the frame piece 44 after being screened by the filter layer 45. Dust with uniform particles is gradually dispersed to the bottom, and is treated by the liquid reaction inside the through pipe 6, so that the equipment has the functions of collecting dust, screening dust, preventing dirty ground, and dust reduction treatment, thereby reducing unnecessary dust reduction costs and improving the practicality of treatment.

[0040] When it is necessary to process the dust particles on the upper part of the filter layer 45, the filter layer 45 is divided into an upper and a lower part due to the effect of bumps and vibrations, and the dust particles in the upper part fall into the notch of the filter layer 45. When the frame member 44 bumps, the gap between the inclined plate member 461 and the filter layer 45 gradually becomes larger, and the other end of the vertical bar 462 is located inside the inclined plate member 461 and is movably installed on the slide plate 43 through the support seat 465. When the frame member 44 slides upward, the frame member 44 is gradually connected to the other end of the vertical bar 462, and the other end of the vertical bar 462 is located on a side close to the inclined plate member 461. When the frame member 44 slides upward, the other end of the vertical bar 462 is squeezed by the upward displacement of the frame member 44. Since the vertical bar 462 itself is an elastic structure, since the frame member 44 is far away from the outermost side of the main beam 31 and is squeezed by the throwing member 33 Under the pressure, the inner side of the frame member 44 close to the main beam 31 gradually sinks downward, and the inclined plate member 461 sinks downward synchronously. Due to the relative force, the other end of the vertical bar 462 forms a bulge, and the depression of the vertical bar 462 is formed before the balance adjustment. The vertical bar 462 itself is deformed, and the vertical bar 462 forms a convex shape. When the vertical bar 462 is convex, the linkage force of 463 changes. The vertical bar 462 drags the curved bar 463 to move, and the comb bar 464 moves with the curved bar 463. The comb bar 464 gradually scrapes the dust on the upper part of the filter layer 45, thereby wiping and breaking the dust blocked in the filter layer 45, realizing the function of dust reduction treatment, reducing the difficulty of breaking and separating the dust in the upper part and interfering with the overall dust reduction efficiency, improving the quality of dust decomposition in the air, and promoting air freshness.

The swing bar 74 is embedded in the inner cavity of the hook 72. A notch corresponding to the swing bar 74 is reserved in the middle of the inner groove of the first clamping plate 71. The hook 72 is an arc-shaped structure. A rod is provided between the first clamping plate 71 and the frame member 44. The hook 72 is symmetrically designed with the center of the torsion bar 73 as a reference. The second clamping plate 75 and the first clamping plate 71 are not exactly the same in specifications and dimensions. The first clamping plate 71 is made of stainless steel.

[0043] When in use, the device is first pushed to a suitable construction project, and then the dust cleaning liquid is added to the inner cavity of the water tank part 5, and enters into the interior of the frame part 44 through the through pipe 6, and the side part 42 is moved by external force to cause the side part 42 to slide up or down along the side wall of the slide plate 43, thereby ensuring that the equipment has the basic conditions for adjusting the height processing and realizing the convenience of subsequent dust removal.

[0044] When dust suppression is required, the height position needs to be fixed, that is, one end of the torsion bar 73 is connected to the output end of the motor, and the torsion bar 73 is energized to rotate, and the torsion bar 73 acts on the first clamping plate 71 to move. Corresponding rotating textures are provided between the torsion bar 73 and the first clamping plate 71, and the torsion bar 73 forms a tendency to rotate and swing. The rotation of the torsion bar 73 causes the two first clamping plates 71 to deform, and the first clamping plate 71 extends into the interior of the angle adjustment device 3. The first clamping plate 71 is limited and gradually slides upward, and the top of the right end of the first clamping plate 71 slides upward, and the first clamping plate 71 slides upward. 71 is connected with the sleeve frame part 44, and the first clamping plate 71 acts on the sleeve frame part 44 to move upward synchronously, and the first clamping plate 71 moves along the inner cavity of the angle adjustment device 3. When the first clamping plate 71 slides to a suitable position, the hook 72 at the bottom is gradually pushed upward, and the hook 72 acts on the swing bar 74 to move. The swing bar 74 is embedded and installed in the inner cavity at the bottom end of the first clamping plate 71, and the swing bar 74 is pushed to the groove of the first clamping plate 71 to form a lock.
