Description

Technical Field

[0001] This invention relates to the field of dust removal technology in building decoration, specifically to an environmentally friendly dust removal device for building decoration projects. Background Technology

[0002] Construction and decoration projects generate a large amount of dust during construction, which not only affects the construction environment and workers' health but also pollutes the surrounding environment. Currently, the most commonly used dust control methods include spray dust suppression and mechanical dust collection.

[0003] However, most existing dust removal devices have the following shortcomings: First, they are single-function, with spraying and vacuuming devices usually being independent equipment that needs to be configured and operated separately, resulting in large space occupation and high costs at the construction site; second, existing devices are mostly fixed installations or only support simple height adjustments, making it impossible to flexibly adjust the angle and orientation of the dust removal components, which is difficult to adapt to the dust removal needs of different heights and locations during decoration and construction, especially in terms of insufficient dust coverage for areas above or below the machine body; third, the dust removal components are mostly rigidly fixed to the main unit using bolt connections, making it cumbersome to replace spray nozzles or vacuum heads, affecting construction efficiency; and fourth, cleaning the dust collection box mostly relies on manual emptying, which is time-consuming, labor-intensive, and prone to causing secondary dust.

[0004] Therefore, there is an urgent need for an environmentally friendly dust removal device for building decoration that integrates spray dust suppression and dust collection, has multi-dimensional adjustable height and angle, and allows for quick disassembly and assembly of dust removal components and easy cleaning of accumulated dust. Summary of the Invention

[0005] To solve the above-mentioned technical problems, an environmentally friendly dust removal device for building decoration engineering is provided. This technical solution solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An environmentally friendly dust removal device for building decoration projects includes a body and a mounting plate. The front and rear sides of the body are fixedly connected to the mounting plate through lifting mechanisms. An adjustment mechanism is provided on the mounting plate. A dust removal mechanism is installed on the body. The dust removal mechanism includes an atomizing nozzle and a suction head. The adjustment mechanism is used to clamp and install the atomizing nozzle or the suction head and to adjust the angle and orientation of the atomizing nozzle or the suction head. The lifting mechanism is used to change the height of the atomizing nozzle or the suction head. Two sets of positioning mechanisms are also installed on the top of the body.

[0007] Preferably, the lifting mechanism includes a first threaded rod and a scissor telescopic component. Fixed frames are fixedly connected to both the front and rear sides of the machine body. The first threaded rod is rotatably connected inside the fixed frame. A first fixed rod is also fixedly installed inside the fixed frame. Two sets of movable frames are slidably connected to the outer wall of the first fixed rod. The two sets of movable frames are respectively threaded to both ends of the outer wall of the first threaded rod, and the threads at both ends of the first threaded rod have opposite directions of rotation.

[0008] Preferably, the interiors of the two sets of movable frames are rotatably connected to the bottom ends of the scissor telescopic member, and the top ends of the scissor telescopic member are rotatably connected to the interiors of the two sets of sliding frames. Both sets of sliding frames are slidably connected to the guide rail, the guide rail is fixedly connected to the interior of the frame, and the top of the frame is fixedly connected to the mounting plate by bolts. A first servo motor is provided on the outer wall of the fixed frame, and the outer end of the first threaded rod is fixedly connected to the output end of the first servo motor.

[0009] Furthermore, the output of the first servo motor drives the first threaded rod to rotate, causing the two sets of movable frames to move closer or further apart. When the two sets of movable frames move closer together, the scissor telescopic component is in an extended state, which also causes the two sets of sliding frames to move closer together, thus causing the mounting plate to move upward. When the two sets of movable frames move further apart, the scissor telescopic component is in a retracted state, which also causes the two sets of sliding frames to move further apart, thus causing the mounting plate to move downward.

[0010] Preferably, the adjustment mechanism includes a first motor fixedly connected to the bottom wall of the mounting plate, the output end of the first motor passing through the bottom wall of the mounting plate and fixedly connected to the rotating frame, a second threaded rod rotatably connected inside the rotating frame, a movable frame threadedly connected to the outer wall of the second threaded rod, the movable frame slidably connected to a second fixed rod, the second fixed rod being fixedly installed inside the rotating frame, and a second servo motor for driving the second threaded rod to rotate being provided on the outer wall of the rotating frame.

[0013] Furthermore, by driving the output end of the first motor to drive the rotating frame to rotate, the moving frame, the first electric push rod, the second electric push rod and the fixed plate as a whole rotate around the output end of the first motor; Furthermore, by driving the output end of the third servo motor, a set of transmission gears and the third threaded rod are rotated as a whole. The rotation of the transmission gears drives the end face gears to rotate, so that all the transmission gears and the third threaded rod rotate synchronously, thereby driving all the clamping parts to move synchronously toward or away from the center position of the fixed plate.

[0014] Preferably, the dust removal mechanism includes a water tank, an inlet pipe, a water pump, an outlet pipe, and an atomizing nozzle. The water tank is fixedly installed at the bottom of the machine body, and the water pump is fixedly installed at the top of the machine body. The input end of the water pump is connected to the water tank through the inlet pipe, and the output end of the water pump is connected to the atomizing nozzle through the outlet pipe.

[0015] Preferably, the dust removal mechanism further includes a collection box, a first dust inlet pipe, a vacuum cleaner, a second dust inlet pipe, and a suction head.

An electric door is rotatably connected to the back of the collection box, and a rod is fixedly installed on the top of both the atomizing nozzle and the suction head. A push-out mechanism is provided inside the collection box.

[0016] Furthermore, when spraying water mist to suppress dust, a water pump delivers water from the water tank to the atomizing nozzles for spraying; while when vacuuming, a vacuum cleaner absorbs the dust and sends it to the collection box.

[0017] Preferably, the positioning mechanism includes a frame fixedly installed on the top of the machine body, a fourth threaded rod rotatably connected inside the frame, the threads at both ends of the fourth threaded rod having opposite directions, and positioning plates threadedly connected to both ends of the outer wall of the fourth threaded rod. A fourth fixed rod is also fixedly installed inside the frame, and both sets of positioning plates are slidably connected to the fourth fixed rod. A fourth servo motor for driving the fourth threaded rod to rotate is installed on the outer wall of the frame.

[0018] Furthermore, by controlling the output of the fourth servo motor to rotate, the fourth threaded rod rotates, causing the two sets of positioning plates to move closer or further apart, thus fixing the atomizing nozzle and the suction head in the dust removal mechanism to the top of the machine body.

[0019] Preferably, the ejection mechanism includes a fifth threaded rod, a fifth fixed rod, a fifth servo motor, and an ejection plate.

[0020] Furthermore, when it is necessary to clean the dust inside the collection box, the electric door is rotated and opened. Then, the output of the fifth servo motor drives the fifth threaded rod to rotate, which moves the ejector plate toward the electric door, thus ejecting the dust quickly and easily.

[0021] Compared with the prior art, the present invention provides an environmentally friendly dust removal device for building decoration projects, which has the following beneficial effects: This invention integrates an atomizing nozzle and a suction head, combining both dust suppression and dust removal functions. The system allows for flexible switching based on actual working conditions, improving dust removal efficiency. A lifting mechanism adjusts the height of the dust removal components, enabling multi-axis adjustment of angle and orientation. This allows for dust suppression in areas above and below the machine, suitable for construction scenarios at different heights. Furthermore, the adjustment mechanism, through clamping components and a fixing plate, allows for quick switching between the atomizing nozzle and the suction head. One device meets multiple dust removal needs, reducing equipment costs. The collection box has a built-in ejection mechanism; opening the electric door automatically ejects accumulated dust, avoiding the tedious manual cleaning and simplifying maintenance.

[0024] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0025] Example 1 Please refer to Figures 1-7As shown, an environmentally friendly dust removal device for building decoration projects includes a body 1 and a mounting plate 101. The front and rear sides of the body 1 are fixedly connected to the mounting plate 101 through a lifting mechanism 2. An adjustment mechanism 3 is provided on the mounting plate 101. A dust removal mechanism 4 is installed on the body 1. The dust removal mechanism 4 includes an atomizing nozzle 405 and a suction head 410. The adjustment mechanism 3 is used to clamp and install the atomizing nozzle 405 or the suction head 410 and to adjust the angle and orientation of the atomizing nozzle 405 or the suction head 410. The lifting mechanism 2 is used to change the height of the atomizing nozzle 405 or the suction head 410. Two sets of positioning mechanisms 5 are also installed on the top of the body 1.

[0026] Example 2 Please refer to Figure 2 As shown, the lifting mechanism 2 includes a first threaded rod 202 and a scissor telescopic component 209.

A first fixed rod 203 is also fixedly installed inside the fixed frame 201. Two sets of movable frames 205 are slidably connected to the outer wall of the first fixed rod 203. The two sets of movable frames 205 are respectively threaded to both ends of the outer wall of the first threaded rod 202, and the threads at both ends of the first threaded rod 202 are in opposite directions.

[0027] Please refer to Figure 2 As shown, the interiors of the two sets of movable frames 205 are rotatably connected to the bottom ends of the scissor telescopic member 209, and the top ends of the scissor telescopic member 209 are rotatably connected to the interiors of the two sets of sliding frames 208.

A first servo motor 204 is provided on the outer wall of the fixed frame 201, and the outer end of the first threaded rod 202 is fixedly connected to the output end of the first servo motor 204.

[0028] Those skilled in the art will understand that the output of the first servo motor 204 drives the first threaded rod 202 to rotate, causing the two sets of movable frames 205 to move closer or further apart. When the two sets of movable frames 205 move closer together, the scissor telescopic member 209 is in an extended state, which also causes the two sets of sliding frames 208 to move closer together, thus causing the mounting plate 101 to move upward. When the two sets of movable frames 205 move further apart, the scissor telescopic member 209 is in a retracted state, which also causes the two sets of sliding frames 208 to move further apart, thus causing the mounting plate 101 to move downward.

[0029] Example 3 Please refer to Figure 3 and Figure 4As shown, the adjustment mechanism 3 includes a first motor 301 fixedly connected to the bottom wall of the mounting plate 101. The output end of the first motor 301 passes through the bottom wall of the mounting plate 101 and is fixedly connected to the rotating frame 302. A second threaded rod 303 is rotatably connected inside the rotating frame 302. A movable frame 306 is threadedly connected to the outer wall of the second threaded rod 303. The movable frame 306 is slidably connected to a second fixed rod 304. The second fixed rod 304 is fixedly installed inside the rotating frame 302. A second servo motor 305 that drives the second threaded rod 303 to rotate is provided on the outer wall of the rotating frame 302.

[0030] Please refer to Figure 3 and Figure 4 As shown, a second motor 307 is provided on the outer wall of the movable frame 306. The output end of the second motor 307 extends into the movable frame 306 and is fixedly connected to the first electric push rod 308 through a connector. The output end of the first electric push rod 308 is fixedly connected to the third motor 309. The output end of the third motor 309 is fixedly mounted on the mounting frame 310.

A fourth motor 311 is provided on the outer wall of the mounting frame 310 to drive the second electric push rod 312 to rotate, and the output end of the second electric push rod 312 is fixedly connected to the fixed disk 313.

[0031] Please refer to Figure 5 As shown, several sets of connecting frames 314 are fixedly connected inside the fixed disk 313. A third threaded rod 315 is rotatably connected inside the connecting frame 314. A third fixed rod 316 is also welded inside the connecting frame 314. A clamping member 319 is slidably connected to the third fixed rod 316. The clamping member 319 is threadedly connected to the outer wall of the third threaded rod 315. A transmission gear 317 is fixedly installed at the outer end of the third threaded rod 315. A set of end face gears 318 is also rotatably connected inside the fixed disk 313. The end face gears 318 mesh with several sets of transmission gears 317. A third servo motor 320 is provided on the outer wall of one set of connecting frames 314. One set of transmission gears 317 is fixedly connected to the output end of the third servo motor 320.

[0032] Those skilled in the art will understand that by driving the output end of the first motor 301 to drive the rotating frame 302 to rotate, the moving frame 306, the first electric push rod 308, the second electric push rod 312 and the fixed plate 313 as a whole rotate around the output end of the first motor 301. Furthermore, by driving the output end of the third servo motor 320, a set of transmission gears 317 and the third threaded rod 315 are rotated as a whole. The rotation of the transmission gear 317 drives the end face gear 318 to rotate, so that all the transmission gears 317 and the third threaded rod 315 rotate synchronously, thereby driving all the clamping parts 319 to move synchronously toward or away from the center position of the fixed plate 313.

[0033] Example 4 Please refer to Figure 2 and Figure 6 As shown, the dust removal mechanism 4 includes a water tank 401, an inlet pipe 402, a water pump 403, an outlet pipe 404, and an atomizing nozzle 405. The water tank 401 is fixedly installed at the bottom of the machine body 1, and the water pump 403 is fixedly installed at the top of the machine body 1. The input end of the water pump 403 is connected to the water tank 401 through the inlet pipe 402, and the output end of the water pump 403 is connected to the atomizing nozzle 405 through the outlet pipe 404.

[0034] Please refer to Figure 1 and Figure 6 As shown, the dust removal mechanism 4 also includes a collection box 406, a first dust inlet pipe 407, a vacuum cleaner 408, a second dust inlet pipe 409, and a suction head 410. The collection box 406 is also fixedly connected to the bottom of the body 1, and the vacuum cleaner 408 is also fixedly installed on the top of the body 1. The input end of the vacuum cleaner 408 is connected to the suction head 410 through the second dust inlet pipe 409, and the output end of the vacuum cleaner 408 is connected to the collection box 406 through the first dust inlet pipe 407. An electric door 412 is rotatably connected to the back of the collection box 406, and a rod 411 is fixedly installed on the top of both the atomizing nozzle 405 and the suction head 410. A push-out mechanism 6 is provided inside the collection box 406.

[0035] Those skilled in the art will understand that when spraying water mist to suppress dust, the water in the water tank 401 is delivered to the atomizing nozzle 405 by the water pump 403 and sprayed out; while when vacuuming, the dust is absorbed by the vacuum cleaner 408 and sent to the collection box 406.

[0036] Example 5 Please refer to Figure 6 As shown, the positioning mechanism 5 includes a frame 501 fixedly installed on the top of the body 1. A fourth threaded rod 502 is rotatably connected inside the frame 501. The threads at both ends of the fourth threaded rod 502 have opposite directions, and positioning plates 505 are threadedly connected to both ends of the outer wall of the fourth threaded rod 502. A fourth fixing rod 503 is also fixedly installed inside the frame 501. Both sets of positioning plates 505 are slidably connected to the fourth fixing rod 503. A fourth servo motor 504 that drives the fourth threaded rod 502 to rotate is installed on the outer wall of the frame 501.

[0037] Those skilled in the art will understand that by controlling the output end of the fourth servo motor 504 to rotate, the fourth threaded rod 502 rotates, causing the two sets of positioning plates 505 to move closer or further apart, thereby fixing the atomizing nozzle 405 and the suction head 410 in the dust removal mechanism 4 to the top of the machine body 1.

[0038] Example 6 Please refer to Figure 7 As shown, the ejection mechanism 6 includes a fifth threaded rod 601, a fifth fixed rod 602, a fifth servo motor 603, and an ejection plate 604. The fifth threaded rod 601 is rotatably connected inside the collection box 406, the fifth fixed rod 602 is welded inside the collection box 406, the fifth servo motor 603 is disposed on the outer wall of the collection box 406, the outer end of the fifth threaded rod 601 is fixedly connected to the output end of the fifth servo motor 603, and the ejection plate 604 is threadedly connected to the outer wall of the fifth threaded rod 601 and slidably connected to the outer wall of the fifth fixed rod 602.

[0039] Those skilled in the art will understand that when it is necessary to clean the dust inside the collection box 406, the electric door 412 is rotated and opened, and then the output end of the fifth servo motor 603 is driven to rotate the fifth threaded rod 601, so that the push plate 604 moves in the direction of the electric door 412, thereby pushing out the dust, which is convenient and quick.

[0040] The working principle of this device is as follows: S1. The machine body 1 in this invention is a trolley that can automatically move in areas requiring dust removal. When water mist spraying is needed to reduce dust, the output of the first motor 301 drives the rotating frame 302 to rotate, causing the moving frame 306, the first electric push rod 308, the second electric push rod 312, and the fixed plate 313 to rotate as a whole to the right side facing the machine body 1. At this time, the first electric push rod 308 and the second electric push rod 312 are in a horizontal state. Furthermore, under the combined action of the output of the first electric push rod 308 and the output of the fourth motor 311, the second electric push rod 312 is in a vertical position. The device moves to the right, causing the fixed plate 313 to move directly above the upper rod 411 of the atomizing nozzle 405. This drives the output end of the second electric push rod 312 to extend, allowing the upper rod 411 of the atomizing nozzle 405 to enter the fixed plate 313. The output end of the third servo motor 320 drives one set of transmission gears 317 and the third threaded rod 315 to rotate as a whole, causing all the clamping parts 319 to move synchronously towards the center position near the fixed plate 313, clamping the upper rod 411 of the atomizing nozzle 405, thus realizing the installation of the atomizing nozzle 405 on the adjustment mechanism 3. S2. Since the machine body 1 has a certain height, when it is necessary to reduce dust in the area above the machine body 1, the atomizing nozzle 405 is kept in a horizontal or upward tilted state by the action of the output end of the second motor 307. Then, in conjunction with the automatic movement of the machine body 1, the adjustable angle of the atomizing nozzle 405, and the extension of the height of the atomizing nozzle 405 by the lifting mechanism 2, water mist can be sprayed to reduce dust in the area above the machine body 1. When dust suppression is required in areas lower than the height of the machine body 1, the output of the second servo motor 305 drives the second threaded rod 303 to rotate, causing the moving frame 306 to move to the position of the rotating frame 302 close to the second servo motor 305. Under the action of the output of the second motor 307, the atomizing nozzle 405 is kept tilted downwards. In the same way, water mist can be sprayed to suppress dust in the area below the machine body 1. S3. Similarly, by installing the vacuum head 410 on the adjustment mechanism 3, it is possible to perform comprehensive vacuuming of the area that needs to be cleaned, which is convenient and quick. When it is necessary to clean the dust inside the collection box 406, the electric door 412 is rotated and opened by driving it. Then, the output end of the fifth servo motor 603 is driven to rotate the fifth threaded rod 601, which causes the push plate 604 to move in the direction of the electric door 412, thus pushing out the dust, which is convenient and quick.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
