The back wall of the recycling box 1, the free end of the filter 3 is located between the spaced limit blocks 4, the rotating ball 7 is movably arranged on the back wall of the recycling box 1, the cantilever 8 and the lever 10 are respectively connected to both sides of the rotating ball 7, and the cantilever 8 is located below the filter 3, and the lever 10 is located outside the back wall of the recycling box 1, the knocking hammer 9 is arranged at the free end of the cantilever 8, and a rectangular notch is provided at the lower part of the back wall of the recycling box 1, the collection box 5 is drawer-styled at the bottom of the inner cavity of the recycling box 1 through the rectangular notch, and the baffle 6 is arranged on the back wall of the collection box 5 and fixed to the recycling box 1 by bolts 61 to cover the rectangular notch.

[0012] Preferably, the air suction pipe 21 and the dust suction pipe 11 are trumpet-shaped pipes, and the trumpet mouth of the air suction pipe 21 is located in the inner cavity of the recovery box 1, and the trumpet mouth of the dust suction pipe 11 is located outside the front wall of the recovery box 1. The setting of the trumpet mouth improves the efficiency of air suction and dust collection, thereby improving the overall dust recovery effect of the device.

[0013] Preferably, a rubber handle 101 is provided at the free end of the lever 10, and a rubber pad 91 is provided on the top surface of the hammer 9. The rubber handle facilitates the operation of the lever and improves the comfort when the lever is moved; the rubber pad protects the filter screen and prevents the hammer from damaging the filter screen surface.

[0014] Preferably, a perspective window 12 is provided in the middle of the side wall of the recovery box 1. Through the transparent window, it is convenient to check the dust recovery situation in the collection box, so as to clean the collection box in time.

[0015] Preferably, an air outlet pipe 22 is provided at the air outlet end of the fan 2.

[0016] The device is placed at the masonry processing site of the construction, the dust suction pipe of the recycling box is facing the dust from the masonry processing, the fan is started, the suction end of the fan sucks air through the suction pipe, the suction pipe absorbs the dust in the air through the suction pipe, so that the dust enters the recycling box through the suction pipe, the dust in the air is filtered through the filter, so that the filtered air enters the fan through the suction pipe, and finally is discharged through the outlet pipe. When the fan is started, the suction force generated by the fan will suck one end of the filter upward, so that the free end of the filter moves upward and presses against the upper When the fan is turned off, the free end of the filter will automatically fall down under the action of its own gravity, causing the free end of the filter to hit the lower limit block, thereby facilitating the cleaning of the dust adsorbed by the filter. At the same time, the lever can be turned to drive the hammer to knock on the filter through the rotating ball and the cantilever, which also has the effect of cleaning the dust. The cleaned dust falls into the collection box for recycling. After observing that the collection box is full of dust through the perspective window, remove the bolts of the baffle, pull the collection box out of the recycling box, and then dump the dust to the recycling area.

[0017] The device sets the filter so that the filter can be cleaned when the fan is started and shut down. The filter can also be knocked by a rotating ball, a cantilever, a hammer and a lever, so that the dust accumulated on the filter falls into the collection box, thereby ensuring the dust collection effect. There is no need to disassemble and clean the filter, which reduces production costs, improves dust recovery efficiency, realizes green construction of masonry processing, and avoids impacts on the health of construction workers and the environment.
