Technical Field
[0001] The invention relates to a dust shaking device for a dust box of a sweeping vehicle. Background Art
[0002] The sweeper is an integrated garbage cleaning device that combines sweeping and vacuuming. During the cleaning process, the sweeper will send dust into the dust box and filter out the dust under the action of the filter cartridge for centralized collection. Some of the dust in the filter cartridge will adhere to the inner wall of the filter cartridge. Over time, the filter holes on the inner wall of the filter cartridge will be clogged with dust, resulting in greater resistance of the filter cartridge and less air volume, which in turn leads to worse filtering effect of the filter cartridge and ultimately causes the failure of the dust suction effect. In order to remove the dust attached to the inner wall of the filter cartridge, the existing method is to frequently remove the dust box and clean the filter cartridge to restore the function of the filter cartridge, and then reinstall the dust box. The operation is cumbersome, the use is troublesome, time-consuming and labor-intensive, and needs further improvement. Summary of the invention

[0019] When in use, two vertically distributed filter cartridges 10 are arranged in the dust box 1 and the two filter cartridges 10 are arranged below the cover plate 5, and the two knocking blocks 19 respectively cooperate with the outer walls of the two filter cartridges 10; the upper end openings of the two filter cartridges 10 are respectively concentrically arranged with the two through holes 52, the box cover 2 is installed on the upper end of the dust box 1, and the two fans 3 arranged in the box cover 2 are respectively arranged above the upper end openings of the two filter cartridges 10, and the two fans 3 are started to run, and then the dust is sucked into the box cover 2 with the help of wind force, and then falls into the two filter cartridges 10 for collection. After accumulation to a certain extent, the two cartridge covers 4 arranged at the bottom of the dust box 1 are opened to remove the dust at one time. The above principle is the prior art; and the feature of the present invention is that before the dust falls into the filter cartridge 10, it will first pass through the two through holes 52; and when a large amount of dust is attached to the filter holes on the inner walls of the two filter cartridges 10, the air inlet resistance will become larger and the air outlet will become smaller, thereby affecting the filter cartridge.

At the same time, the cover plate 5 is also flexibly connected to the dust box 1 with the help of four first springs 7 and four knob screws 8. The vibration of the vibration motor 6 will eventually drive the traction rod 16 to move back and forth in the sleeve 17 with the help of the cover plate 5 and the bottom plate 11, thereby driving the upper ends of the two rocker rods 18 to move back and forth up and down. Then, the slide grooves 181 on the two rocker rods 18 will slide back and forth along the two pin shafts 20 respectively, thereby driving the bending sections 182 on the two rocker rods 18 to frequently open outward and move inward, thereby driving the two knocking blocks 19 to frequently knock on the outer walls of the two filter cartridges 10, and then shake off the dust attached to the inner wall of the filter cartridge 10 to restore the patency of the filter holes on the inner wall of the filter cartridge 10, thereby restoring the filtering effect.
[0020] The present invention can automatically shake off the dust attached to the inner wall of the filter cartridge 10 to restore the function of the filter cartridge 10. There is no need to frequently disassemble and assemble the dust box to clean the filter cartridge. The operation is simple, which greatly facilitates use and saves time and effort.
