[0002] A construction site is a building construction site, which refers to the construction activities such as house construction, civil engineering, equipment installation, pipeline laying, etc. for industrial and civil projects. It is an approved construction site and a place where humans conduct safe production, civilized work, and construction, including all areas on land, sea, and air where construction work can be carried out. Since a large amount of dust particles are easily generated during the construction process, dust removal is usually required to ensure the health of workers and environmental safety.

[0003] At present, when the existing construction site dust removal equipment is in use, most of them use fans to absorb the dust on the construction site, and then use filters to intercept and filter the dust, and finally discharge clean air. Since the filter holes on the surface of the filter are very easy to accumulate dust, causing the filter holes to be blocked, the filtering and dust removal effect will be affected over time. Frequent shutdowns for replacements will greatly affect work efficiency, and the blocked dust is not easy to clean, resulting in poor use effect. Summary of the invention

With the continuous knocking of the baffle assembly and the knocking block, the dust impurities in the filter holes can be shaken out and introduced into the dust collecting box; and with the switching of the filter screens, clean water can be controlled to flush the inclined filter screen below, and the flushed sewage can be made to flow into the liquid collecting box; by regularly controlling the filter screen to cyclically switch and clean, it can be ensured that the clean and tidy filter screens can always intercept and filter the dust impurities on the construction site, which greatly ensures the dust removal effect, and there is no need for repeated disassembly and cleaning, and it is extremely convenient and efficient to use, so as to solve the above-mentioned deficiencies in the technology.

The suction fan (8) generates suction force, so that dust at the construction site can be sucked into the dust removal box (4) through the suction hood (6). The sucked air can be filtered through the filter screen (17) vertically installed in the dust removal box (4), so that dust impurities are intercepted, and clean air can pass through the filter screen (17) and be discharged from the air duct (7); S2, the intercepted dust impurities can fall along the filter screen (17) toward the box seat (5), and are guided by the inclined filter screen (17) below to the inner bottom end of the box seat (5). Under the isolation of the baffle plate (14), the dust impurities can fall into the dust collecting box (11) to be collected and stored, and the inspection door (12) can be opened for cleaning; S3, and by starting the driving motor (23), the driving motor (23) drives the first rotating handle (24) to rotate, and then the first rotating handle (24) can drive the second rotating handle (25) to move, so that the second rotating handle (25) drives the knocking block (26) to move, and under the support and limit of the limit rod (27), the knocking block (26) can be driven to reciprocate and continuously knock the fixed frame (16), so that the filter screen (17) on the fixed frame (16) vibrates, so that the dust impurities can be quickly guided to the inner bottom end of the box seat (5); S4, the baffle (14) is driven down by the electric push rod (13) to remove the obstruction of the baffle (14) interlacing between the two filter screens (17), and then the driving motor (21) drives the driving wheel (19) to rotate, so that the driving wheel (19) drives the driven wheel (18) to rotate through the belt (20), and then the driven wheel (18) can drive the rotating rod (15) to rotate, so that the rotating rod (15) drives the three fixed frames (16) thereon to rotate, so that the fixed frames (16) can rotate. 16) drives the plurality of filter screens (17) to shift positions, so that the filter screens (17) with dust impurities accumulated and blocked in the filter holes are transferred to the box seat (5), while the clean and tidy filter screens (17) are transferred to the dust removal box (4) and abut against the arc-shaped inner wall, and then the baffle (14) is controlled to rise and reset, and because the dirty surface of the filter screen (17) transferred to the box seat (5) faces downward, with the continuous knocking of the knocking block (26), the dust impurities in the filter holes can be shaken out and introduced into the dust collection box (11); S5, with the switching of the filter screen (17), when a filter screen (17) is switched to the water delivery pipe (30), the water pump (29) is started to pump clean water in the water storage tank (28) into the water delivery pipe (30), and then the clean water is sprayed out from each nozzle (31) through the water delivery pipe (30), and the sprayed clean water can wash the filter screen (17) inclined below, and under the isolation of the baffle plate (14), the washed sewage can flow into the liquid collection box (9) and can be discharged to the outside through the discharge pipe (10); S6. By regularly repeating steps S4-S5, the filter (17) is cyclically switched and cleaned, thereby ensuring that the clean and tidy filter (17) can always intercept and filter the dust impurities on the construction site, greatly ensuring the dust removal effect, and there is no need for repeated disassembly and cleaning, which is extremely convenient and efficient to use.
