[0020] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0021] like Figure 1-5 As shown, a construction dust removal fence includes a support base 1, support plates 5 are respectively provided at both ends of the support base 1, and an adjustment structure is provided on the support plate 5. The adjustment structure includes a plurality of baffles 12 rotatably connected to the support base 1 and with the same rotation direction, and a filter screen 2 detachably connected to the support plate 5 is provided at the front end of the baffle 12.

[0022] When the utility model is in use, the support base 1 supports the support plate 5, and the support base 1 is fixed around the construction site. When the construction environment needs to be ventilated, the baffle 12 can be driven to rotate to a state perpendicular to the filter 2. The gap between the baffles 12 is the largest, and the ventilation volume can be increased. The filter 2 can block the dust passing through the baffle 12 to prevent the dust in the construction site from adhering to the baffle 12. When encountering strong winds, the baffle 12 can be rotated to a state parallel to the filter 2 to close the gap between the baffles 12, which can effectively prevent the construction site from being blown away, causing dust in the construction site to fly.

[0023] The adjustment structure also includes a worm 7 rotatably connected to the support plate 5, the worm 7 is meshed with a worm wheel 8, the worm wheel 8 is fixedly connected to a transmission rod 9, and a plurality of active bevel gears 10 are evenly arranged on the transmission rod 9. An upper rotating shaft 15 and a lower rotating shaft 14 are respectively arranged in the middle of the upper and lower ends of the baffle 12, and a driven bevel gear 11 meshed with the active bevel gear 10 is arranged on the upper rotating shaft 15.

[0024] like Figure 1 and 2 As shown, a handle 6 is provided at one end of the worm 7, and the worm 7 is driven to rotate by the handle 6, and the worm 7 drives the worm wheel 8 to rotate, and the worm wheel 8 drives the transmission rod 9 to rotate. During the rotation of the transmission rod 9, the active bevel gear 10 is driven to rotate at the same time, and the active bevel gear 10 drives the driven bevel gear 11 to rotate respectively. The driven bevel gear 11 drives the baffle 12 to rotate through the upper rotating shaft 15 and the lower rotating shaft 14. When it is necessary to ventilate the construction environment, the baffle 12 can be driven to rotate to a state perpendicular to the filter 2. The gap between the baffles 12 is the largest, which can increase the ventilation volume. When encountering strong wind weather, the baffle 12 can be rotated to a state parallel to the filter 2, and the gap between the baffles 12 is closed, which can effectively prevent the construction site from being blown and causing dust to fly in the construction site.

[0025] A plurality of drainage grooves 3 are evenly arranged on the support base 1 , and a supporting rotating cylinder 16 rotatably connected to the lower rotating shaft 14 is arranged in the drainage groove 3 .

[0026] like Figure 5 As shown, when water accumulates on the construction site, the water can be discharged through the drainage trough 3 due to the effect of the baffle 12, and the support drum 16 is rotatably connected to the lower rotating shaft 14, thereby supporting and limiting the rotation of the baffle 12.

[0027] The two ends of the filter screen 2 are respectively provided with limit plug plates 13 , and one end of the support plate 5 is respectively provided with a limit block 17 slidably connected to the limit plug plates 13 .

[0028] like Figure 1 and 4As shown, a mounting hole 4 is provided on the limit block 17, and the limit block 17 is fixed on the support plate 5 through the mounting hole 4. When the filter screen 2 is installed, the limit plug plates 13 at both ends of the filter screen 2 can be inserted into the inner wall of the limit block 17, and the position of the filter screen 2 can be fixed by the limit block 17. When the filter screen 2 needs to be replaced and cleaned, the limit plug plates 13 can be pulled out of the limit block 17, which is convenient for simple disassembly, replacement and installation of the filter screen 2.

[0029] The intervals between the baffles 12 are the same, and the length of the intervals is the same as the width of the baffles 12 .

[0030] like Figure 2 As shown, since the upper end of the baffle 12 rotates around the upper rotating shaft 15 in the middle, when wind blows, the baffle 12 can be completely rotated to a state parallel to the support base 1. At this time, since the length of the spacing is the same as the width of the baffle 12, gaps between the baffles 12 can be avoided, which can effectively prevent wind from entering the construction site and causing dust to be raised.

[0031] The filter screen 2 is evenly provided with a plurality of filter holes, and the height of the filter screen 2 is greater than the height of the baffle 12 .

[0032] like Figure 1 As shown, the filter screen 2 can filter the dust generated during the construction process to prevent it from adhering to the baffle 12 and making it inconvenient to clean.

[0033] The working process of the utility model is as follows: when the utility model is in use, the support base 1 supports the support plate 5, fixes the support base 1 around the construction site, drives the worm 7 to rotate through the rotating handle 6, drives the worm 7 to rotate, drives the worm wheel 8 to rotate, and drives the transmission rod 9 to rotate. During the rotation of the transmission rod 9, the active bevel gear 10 is driven to rotate at the same time, and the active bevel gear 10 drives the driven bevel gear 11 to rotate respectively. The driven bevel gear 11 drives the baffle 12 to rotate through the upper rotating shaft 15 and the lower rotating shaft 14. When it is necessary to ventilate the construction environment, the baffle 12 can be driven to rotate to a state perpendicular to the filter screen 2. The gap between the baffles 12 is the largest, which can increase the ventilation volume. When encountering strong wind weather, the baffle 12 can be rotated to a state parallel to the filter screen 2, and the gap between the baffles 12 is closed, which can effectively block the blowing of the construction site, causing dust to fly in the construction site.

[0034] The filter 2 can block the dust passing through the baffle 12 to prevent the dust in the construction site from adhering to the baffle 12, and when the filter 2 needs to be replaced and cleaned, the limit plug 13 can be pulled out of the limit block 17, so that the filter 2 can be easily disassembled and replaced.

[0035] When water accumulates in the construction site, the water can be discharged through the drainage trough 3 due to the effect of the baffle 12 .

[0036] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
