Technical Field

[0001] This invention relates to the field of auxiliary equipment for construction engineering, and in particular to a waterless dust control device for construction engineering. Background Technology

[0002] Dust is an open source of pollution that is caused by dust on the ground being blown into the atmosphere by wind, human activity, or other means. It is an important component of total suspended particulate matter in ambient air.

[0003] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of buildings, including foundation construction, main structure construction, roofing construction, and decoration construction. A large amount of dust is often generated at construction sites.

[0004] Currently, water spraying is commonly used at construction sites to reduce airborne dust. However, while this method solves the problem, it also has the following drawbacks:

[0005] Using water spraying to treat dust results in a significant waste of water resources and makes roads slippery, affecting pedestrian traffic. Therefore, we propose a waterless dust treatment device for construction projects. Summary of the Invention

[0006] Purpose of the Invention: The purpose of this invention is to provide a waterless dust control device for construction projects, which solves the problems of water waste and slippery roads affecting pedestrian traffic caused by the water spraying method used in the existing construction dust control technology. This invention achieves efficient adsorption and interception of dust generated during construction without the need for water, effectively reducing the dust content in the air in the construction area, improving the construction environment, saving water resources, avoiding traffic safety hazards caused by slippery roads, and having a simple structure, convenient operation, and adaptability to the dust control needs of various construction scenarios.

[0007] Technical solution: A waterless dust control device for construction engineering, including a dust collection box, a dust collection fan fixedly installed on the front surface of the dust collection box, a dust collection pipe rotatably connected to the top of the dust collection box via a rotating shaft, and two filter boxes arranged inside the dust collection box;

[0008] A spur gear is fixedly connected to the outer wall of the suction pipe. A motor is fixedly connected to the upper surface of the suction box and to the left of the suction pipe. An incomplete gear is fixedly connected to the top of the output shaft of the motor. The outer wall of the incomplete gear meshes with the outer wall of the spur gear.

[0009] Furthermore, a base plate is fixedly connected to the bottom of the vacuum box, and multiple casters are fixedly connected to the lower surface of the base plate.

[0010] Furthermore, a handle is fixedly connected to the upper surface of the base plate and to the left of the dust collection box, and a sponge sleeve is fixedly connected to the outer wall of the handle.

[0011] Furthermore, a fixing strip is fixedly connected to the top of the dust collection box and to the right of the dust collection pipe. Two crossbars are slidably connected inside the fixing strip. An L-shaped toothed rod is fixedly connected to the left end of the two crossbars. The left end of the L-shaped toothed rod meshes with the outer wall of the spur gear. A spring is fixedly connected to the opposite side of the L-shaped toothed rod and to the outer wall of the two crossbars.

[0012] Furthermore, inside the dust collection box and below the two filter boxes, there are shafts rotatably connected via pivots. Multiple cams are fixedly connected to the outer wall of the shaft. The left end of the shaft extends through to the left side of the dust collection box and is fixedly connected to a drive wheel. The outer walls of the two drive wheels are connected together by a drive belt. An L-shaped bracket is fixedly connected to the left side of the dust collection box.

[0026] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example

[0028] like Figure 1 , Figure 2 and Figure 3As shown, a waterless dust treatment device for construction engineering is provided, including a dust collection box 1, a dust collection fan 2 fixedly installed on the front surface of the dust collection box 1, a dust collection pipe 3 rotatably connected to the top of the dust collection box 1 through a rotating shaft, and two filter boxes 4 arranged inside the dust collection box 1.

[0029] A circular gear 5 is fixedly connected to the outer wall of the suction pipe 3. A motor 6 is fixedly connected to the upper surface of the suction box 1 and to the left of the suction pipe 3. An incomplete gear 7 is fixedly connected to the top of the output shaft of the motor 6. The outer wall of the incomplete gear 7 meshes with the outer wall of the circular gear 5.

[0030] A fixing strip 12 is fixedly connected to the top of the dust collection box 1 and to the right of the dust collection pipe 3. Two crossbars 13 are slidably connected inside the fixing strip 12. An L-shaped toothed rod 14 is fixedly connected to the left end of the two crossbars 13. The left end of the L-shaped toothed rod 14 meshes with the outer wall of the spur gear 5. Springs 15 are fixedly connected to the opposite side of the L-shaped toothed rod 14 and the outer wall of the two crossbars 13.

[0031] When in use, start motor 6. The output shaft of motor 6 drives the incomplete gear 7 to rotate. When the incomplete gear 7 meshes with the spur gear 5, it will drive the spur gear 5 and the suction pipe 3 fixedly connected to it to rotate the suction direction in a small amplitude. At this time, under the meshing action of the spur gear 5, the L-shaped toothed rod 14 slides to the right along the fixed bar 12 through the two crossbars 13 and squeezes the spring 15 to make it elastically deformed.

[0032] When the incomplete gear 7 disengages from the sprocket 5, the spring 15 returns to its elastic deformation, and the tip of the L-shaped rack 14 abuts against the sprocket 5 for positioning.

[0033] Through the above movements, the intermittent rotation direction and positioning of the suction pipe 3 are achieved, and the suction angle of the suction pipe 3 can be flexibly adjusted to expand the dust adsorption range. At the same time, the suction fan 2 is started, and the suction fan 2 generates negative pressure, which sucks the dust in the construction area into the dust collection box 1 through the suction pipe 3. The dust is then intercepted and filtered by two filter boxes 4 to achieve waterless dust collection and dust reduction.

[0034] like Figure 1 As shown, a base plate 8 is fixedly connected to the bottom of the dust collection box 1, and multiple casters 9 are fixedly connected to the lower surface of the base plate 8;

[0035] A handle 10 is fixedly connected to the upper surface of the base plate 8 and to the left of the dust collection box 1, and a sponge sleeve 11 is fixedly connected to the outer wall of the handle 10.

[0036] Operators can hold the handle 10 with the sponge sleeve 11 and use the multiple casters 9 on the lower surface of the base plate 8 to move the entire device flexibly within the construction area. The sponge sleeve 11 increases the friction between the hand and the handle 10, improving grip comfort and preventing slippage during prolonged gripping. It also allows for flexible adjustment of the dust collection location based on the distribution of construction dust, ensuring comprehensive dust treatment within the construction area.

[0037] like Figure 4 , Figure 5 and Figure 6 As shown, inside the dust collection box 1 and below the two filter boxes 4, there are shafts 16 rotatably connected by a pivot. Multiple cams 17 are fixedly connected to the outer wall of the shaft 16. The left end of the shaft 16 extends through to the left side of the dust collection box 1 and is fixedly connected to a drive wheel 18. The outer walls of the two drive wheels 18 are connected to a drive belt 19. An L-shaped bracket 20 is fixedly connected to the left side of the dust collection box 1. A motor 21 is fixedly connected to the inner side of the L-shaped bracket 20. The right end of the output shaft of the motor 21 is fixedly connected to the left side of the drive wheel 18 located above the left side of the dust collection box 1.

[0038] The right side of the filter box 4 extends through to the right side of the dust collection box 1 and is fixedly connected to a handle 22;

[0039] Multiple movable plates 23 are provided on the inner side of the filter box 4. Two striking blocks 24 are fixedly connected to the lower surface of the movable plate 23. A conical push rod 25 is fixedly connected to the center of the lower surface of the movable plate 23. The bottom end of the conical push rod 25 extends through to the bottom of the filter box 4 and contacts the top of the outer wall of the cam 17. A spring 26 is fixedly connected to the opposite side of the movable plate 23 and the filter box 4 and to the outside of the conical push rod 25.

[0040] After prolonged use, a large amount of dust will accumulate inside the filter box 4, which can easily cause filter blockage and affect the dust collection effect. At this time, the motor 21 fixed on the L-shaped bracket 20 can be started. The output shaft of the motor 21 drives the transmission wheel 18 fixedly connected to it to rotate. The transmission wheel 18 drives another transmission wheel 18 and the corresponding shaft 16 to rotate synchronously through the transmission belt 19. When the shaft 16 rotates, it drives multiple cams 17 on its outer side wall to rotate. During the rotation of the cams 17, they will continuously squeeze the conical push rod 25, pushing the conical push rod 25 to move the movable plate 23 upward and squeeze the spring 26. When the protruding end of the cam 17 disengages from the conical push rod 25, the spring 26 restores its elastic deformation, driving the movable plate 23 and the striking block 24 to return to their original position downward. The striking block 24 strikes the inner wall of the filter box 4. Through reciprocating striking, the dust attached to the inner wall of the filter box 4 is removed, realizing the self-cleaning of the filter box 4.

[0041] When self-cleaning cannot completely remove the clogged dust, you can hold handle 22 and pull the filter box 4 out from the right side of the dust collection box 1 for manual cleaning or replacement. After cleaning, push the filter box 4 back into the dust collection box 1 to ensure that the device continues to work stably.

[0042] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
