Description

Technical Field

[0001] This invention belongs to the field of epoxy flooring technology, specifically an epoxy flooring construction device. Background Technology

[0002] Epoxy flooring is a high-strength, wear-resistant, and aesthetically pleasing flooring option. It boasts advantages such as seamless construction, a solid texture, excellent chemical resistance, corrosion resistance, dust resistance, easy maintenance, and low upkeep costs. Epoxy flooring can be designed in various ways to meet different application requirements, including thin-layer coatings, 1-5mm thick self-leveling floors, anti-slip and wear-resistant coatings, mortar-type coatings, anti-static coatings, and anti-corrosion coatings.

[0003] Some technical solutions for epoxy flooring have also emerged in the prior art. For example, a Chinese patent with application number 2020108173184 discloses a floor coating construction surface treatment device, which includes a bottom plate and a top plate arranged concentrically, and the top plate and the bottom plate are connected by three support rods evenly distributed around the circumference; the material storage mechanism includes an upper movable plate and a lower movable plate sleeved on the support rods.

[0004] Currently, in existing technologies, traditional epoxy flooring construction generates a large amount of dust during the grinding process when the construction equipment comes into contact with the floor. Traditional construction equipment does not have a dust treatment device. Through long-term use and observation, we have found that if the dust is not treated, it will cause harm to the construction workers. Therefore, we propose an epoxy flooring construction device. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies and solve the problem of excessive dust generated during the grinding of epoxy flooring by the construction equipment, which lacks a fume treatment device, this invention proposes an epoxy flooring construction device.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: An epoxy flooring construction device according to this invention includes a main body; a grinding device is installed inside the main body; a negative pressure collection device is fixedly connected to the top of the main body; a suction pipe is installed at the bottom of the negative pressure collection device and penetrates the top side wall of the main body; a suction port is fixedly connected to the side wall of the suction pipe at a position corresponding to the grinding disc of the grinding device; a first bracket is fixedly connected to the inner side wall of the suction pipe; a rotating shaft is rotatably connected to the middle of the first bracket; a spiral impeller is fixedly connected to the middle of the rotating shaft at a position above the suction port; a rotating head is fixedly connected to the bottom end of the rotating shaft; the rotating head is rotatably connected to the bottom end of the suction pipe. When in use, the main unit carries a grinding device to perform grinding on the epoxy floor. During the grinding process, dust is generated. At this time, the negative pressure collection device is turned on. Under the action of atmospheric pressure, the dust near the suction port and the rotating head is sucked into the suction pipe, thereby cleaning the dust near the grinding disc at the bottom of the grinding device. This avoids the dust generated during grinding from affecting the construction personnel. Moreover, when there is air flow inside the suction pipe, the spiral impeller will drive the rotating shaft to rotate, which in turn drives the rotating head to rotate at the bottom of the suction pipe. At this time, the rotating head will suck in the dust in the circular area at the bottom of the suction pipe, increasing the suction range.

[0007] Furthermore, a horn-shaped dust collection pipe is rotatably connected to the side wall of the rotating head; by adding a horn-shaped dust collection pipe to the rotating head, the air intake can be expanded during the rotating dust collection process, thereby further improving the dust collection range.

[0008] Furthermore, a gear is fixedly connected to the middle of the trumpet-shaped dust collection pipe; a gear plate is fixedly connected to the dust collection pipe at a position corresponding to the gear; the gear meshes with the gear plate; multiple sets of brush seats are fixedly connected to the middle of the trumpet-shaped dust collection pipe; cleaning brushes are provided inside the brush seats; during the process of the rotating head driving the trumpet-shaped dust collection pipe to rotate at the bottom of the dust collection pipe, the trumpet-shaped dust collection pipe rotates on the rotating head under the action of the gear meshing with the gear plate. At this time, the cleaning brushes on the brush seats will sweep the dust on the epoxy floor, sweeping up and removing the dust that cannot be directly sucked up by the suction port and the trumpet-shaped dust collection pipe, increasing the cleanliness of the floor after the main body construction, and avoiding the problem of secondary pollution of the floor caused by dust and impurities remaining on the floor after construction.

[0009] Furthermore, an elastic rope is fixedly connected to the inner wall of the brush holder; a pull rod is fixedly connected to the middle of the elastic rope; the end of the pull rod is fixedly connected to the cleaning brush; during the rotation of the trumpet-shaped dust collection pipe, the cleaning brush will move to the outside of the brush holder under the support of the elastic rope, thereby increasing the length of the cleaning brush extending out of the brush holder, avoiding situations where the cleaning brush cannot reach areas with depressions in the ground, and increasing the cleaning range that the cleaning brush can clean. When the trumpet-shaped dust collection pipe is not rotating, the cleaning brush will be pulled back into the brush holder by the elastic rope, avoiding the wear problem caused by the cleaning brush continuously contacting the ground during the transportation and movement of the main body.

[0010] Furthermore, a set of limiting blocks are fixed to the side wall of the trumpet-shaped dust collection pipe inside the brush holder; a counterweight ball is provided between the limiting blocks; a baffle is provided at the bottom end of the pull rod between the two limiting blocks; during the rotation of the trumpet-shaped dust collection pipe, as the cleaning brush moves outward from the brush holder, the counterweight ball between the limiting blocks will squeeze the pull rod through the baffle, increasing the length of the cleaning brush extending out of the brush holder, further improving the cleaning range of the cleaning brush. Moreover, when the speed of the trumpet-shaped dust collection pipe is relatively slow, the counterweight ball will intermittently strike the pull rod under the action of gravity, removing dust from the cleaning brush and increasing the cleanliness of the cleaning brush.

[0011] Furthermore, multiple sets of S-shaped support frames are fixedly connected to the cleaning brush; spring pieces are fixedly connected between the multiple sets of S-shaped support frames; after the S-shaped support frames on the cleaning brush extend out of the brush seat port, the spring pieces between the S-shaped support frames will open the S-shaped support frames, increasing the cleaning range of the cleaning brush; after the cleaning brush retracts into the brush seat, the port of the brush seat will squeeze the spring pieces, reducing the distance between the S-shaped support frames and reducing the space occupied by the cleaning brush.

[0012] Furthermore, the S-shaped support frame is equipped with multiple sets of cleaning strips; a rubber sheet is fixed to the top of each cleaning strip; the length of each cleaning strip is shorter than the length of the cleaning brush; when encountering large pieces of dust on the epoxy floor during construction that are difficult to sweep up with the cleaning brush, the cleaning strip and the rubber sheet will sweep them up so that they can be sucked into the funnel-shaped dust collection pipe, further increasing the cleanliness of the floor after the main body is constructed.

[0013] The beneficial effects of this invention are:

[0014] 1. This invention provides an epoxy flooring construction device. By adding a dust collection device inside the epoxy flooring construction device, the dust generated near the grinding device can be collected through the operation of the negative pressure device, the dust suction pipe and the dust suction port during the operation of the construction device, thus avoiding the problem that the large amount of dust generated during the grinding of the flooring will affect the health of the construction workers.

[0015] 2. In this invention, by adding a rotatable, funnel-shaped dust collection pipe to the bottom of the suction pipe, the range of dust collection can be increased, further reducing the dust content inside the construction device and preventing a single suction pipe from being unable to collect dust in all aspects.

[0016] 3. In this invention, by adding a cleaning brush to the outside of the trumpet-shaped dust collection pipe, dust on the ground that cannot be sucked up by the suction pipe can be swept up and then sucked up through the trumpet-shaped dust collection pipe and the suction port, making the epoxy floor cleaner and tidier after the construction device has passed.

The main body 1 carries the grinding device 11 to perform grinding on the epoxy floor. During the grinding process, dust will be generated. At this time, the negative pressure collection device 2 is turned on. Under the action of atmospheric pressure, the dust near the suction port 22 and the rotating head 33 will be sucked into the suction pipe 21, thereby cleaning the dust near the grinding disc at the bottom of the grinding device 11 and avoiding the problem of dust affecting the construction personnel. Moreover, when there is air flow inside the suction pipe 21, the spiral impeller 32 will drive the rotating shaft 31 to rotate, which will drive the rotating head 33 to rotate at the bottom of the suction pipe 21. At this time, the rotating head 33 will suck in the dust in the circular area at the bottom of the suction pipe 21, increasing the suction range.

[0029] In one embodiment of the present invention, a horn-shaped dust collection pipe 34 is rotatably connected to the side wall of the rotating head 33; by adding the horn-shaped dust collection pipe 34 to the rotating head 33, the air intake can be expanded during the rotating dust collection process, thereby further improving the dust collection range.

[0030] In one embodiment of the present invention, a gear 341 is fixedly connected to the middle of the trumpet-shaped dust collection pipe 34; a gear disc 342 is fixedly connected to the dust collection pipe 21 at a position corresponding to the gear 341; the gear 341 meshes with the gear disc 342; multiple sets of brush seats 35 are fixedly connected to the middle of the trumpet-shaped dust collection pipe 34; a cleaning brush 351 is provided inside the brush seat 35; during the process of the rotating head 33 driving the trumpet-shaped dust collection pipe 34 to rotate at the bottom of the dust collection pipe 21, the trumpet-shaped dust collection pipe 34 rotates on the rotating head 33 under the action of the gear 341 meshing with the gear disc 342. At this time, the cleaning brush 351 on the brush seat 35 will sweep the dust on the epoxy floor, sweeping up and removing the dust that cannot be directly sucked up by the suction port 22 and the trumpet-shaped dust collection pipe 34, increasing the cleanliness of the floor after the construction of the main body 1, and avoiding the problem of secondary pollution of the floor caused by dust and impurities remaining on the floor after construction.

When the trumpet-shaped dust collection pipe 34 is not rotating, the cleaning brush 351 will be pulled back into the brush holder 35 by the elastic rope 352, avoiding the wear problem caused by the cleaning brush 351 continuously contacting the ground during the transportation and movement of the main body 1.

[0032] In one embodiment of the present invention, a set of limiting blocks 36 are fixedly connected to the side wall of the trumpet-shaped dust collection pipe 34 inside the brush seat 35; a counterweight ball 361 is provided between the limiting blocks 36; a baffle is provided at the bottom end of the pull rod 353 between the two limiting blocks 36; during the rotation of the trumpet-shaped dust collection pipe 34, as the cleaning brush 351 moves outward from the brush seat 35, the counterweight ball 361 between the limiting blocks 36 will squeeze the pull rod 353 through the baffle, thereby increasing the length of the cleaning brush 351 extending out of the brush seat 35, further improving the cleaning range of the cleaning brush 351. Moreover, when the speed of the trumpet-shaped dust collection pipe 34 is relatively slow, the counterweight ball 361 will intermittently strike the pull rod 353 under the action of gravity, removing dust from the cleaning brush 351 and increasing the cleanliness of the cleaning brush 351.

[0033] In one embodiment of the present invention, multiple sets of S-shaped support frames 37 are fixedly connected to the cleaning brush 351; spring pieces 371 are fixedly connected between the multiple sets of S-shaped support frames 37; after the S-shaped support frames 37 on the cleaning brush 351 extend out of the brush seat 35 port, the spring pieces 371 between the S-shaped support frames 37 will open the S-shaped support frames 37, increasing the cleaning range of the cleaning brush 351; after the cleaning brush 351 retracts into the brush seat 35, the port of the brush seat 35 will squeeze the spring pieces 371, reducing the distance between the S-shaped support frames 37 and reducing the space occupied by the cleaning brush 351.

[0034] In one embodiment of the present invention, the S-shaped support frame 37 is provided with multiple sets of cleaning strips 372; a rubber sheet 373 is fixedly attached to the top of the cleaning strip 372; the length of the cleaning strip 372 is shorter than the length of the cleaning brush 351; when encountering large pieces of dust on the epoxy floor during construction that are difficult to sweep up by the cleaning brush 351, the cleaning strip 372 and the rubber sheet 373 will sweep them up so that they can be sucked into the trumpet-shaped dust collection pipe 34, further increasing the cleanliness of the floor after the main body 1 is constructed.

[0035] Working Principle: During use, the main body 1 carries the grinding device 11 to perform grinding on the epoxy floor. Dust is generated during the grinding process. At this time, the negative pressure collection device 2 is activated. Under atmospheric pressure, the dust near the suction port 22 and the rotating head 33 is sucked into the suction pipe 21, thus cleaning the dust near the grinding disc at the bottom of the grinding device 11 and preventing dust from affecting the workers. Furthermore, when there is airflow inside the suction pipe 21, the spiral impeller 32 drives the rotating shaft 31 to rotate, which in turn drives the rotating head 33 to rotate at the bottom of the suction pipe 21. The rotating head 33 then sucks in dust within a circular area at the bottom of the suction pipe 21, increasing the suction range. A funnel-shaped dust collection pipe 34 is added to the head 33, which can expand the suction port and further increase the suction range during the rotational suction process. As the rotating head 33 drives the funnel-shaped dust collection pipe 34 to rotate at the bottom of the suction pipe 21, the funnel-shaped dust collection pipe 34 rotates on the rotating head 33 through the meshing of gear 341 and gear disc 342. At this time, the cleaning brush 351 on the brush holder 35 will sweep the dust on the epoxy floor, sweeping up and removing the dust that cannot be directly sucked up by the suction port 22 and the funnel-shaped dust collection pipe 34, increasing the cleanliness of the floor after the main body 1 is installed, and avoiding the problem of secondary pollution of the floor caused by residual dust and impurities. During the rotation of the funnel-shaped dust collection pipe 34, the cleaning brush 351... Supported by the elastic rope 352, the sweeping brush 351 moves outward from the brush holder 35, thereby increasing the length of the sweeping brush 351 extending beyond the brush holder 35. This prevents the sweeping brush 351 from missing areas due to depressions in the floor, increasing the cleaning range of the sweeping brush 351. When the trumpet-shaped dust collection pipe 34 is not rotating, the sweeping brush 351 is pulled back into the brush holder 35 by the elastic rope 352, avoiding wear caused by continuous contact with the ground during the transport and movement of the main body 1. During the rotation of the trumpet-shaped dust collection pipe 34, as the sweeping brush 351 moves outward from the brush holder 35, the counterweight ball 361 between the limiting blocks 36 presses the pull rod 353 through the baffle, causing the sweeping brush 351 to move outward from the brush holder 35. The increased length of the sweeping brush 351 extending beyond the brush holder 35 further enhances its cleaning range. Furthermore, when the flared dust collection pipe 34 rotates at a slower speed, the counterweight ball 361 intermittently strikes the pull rod 353 under the influence of gravity, removing dust from the sweeping brush 351 and increasing its cleanliness. After the S-shaped support frame 37 on the sweeping brush 351 extends beyond the brush holder 35, the spring pieces 371 between the S-shaped support frames 37 open them, further increasing the cleaning range of the sweeping brush 351. When the sweeping brush 351 retracts into the brush holder 35, the ends of the brush holder 35 compress the spring pieces 371, reducing the distance between the S-shaped support frames 37 and minimizing the space occupied by the sweeping brush 351.When encountering large clumps of dust on the epoxy floor that are difficult to sweep up by the cleaning brush 351 during construction, the cleaning strip 372 and rubber sheet 373 will sweep them up, allowing them to be sucked into the funnel-shaped dust collection pipe 34, further increasing the cleanliness of the floor after construction.
