[0024] By adopting the above technical solution, when the back blowing air pipe 4 blows air to clean the filter cloth 8, the second motor 21 is started. The second motor 21 drives the upper rotating shaft 24 to rotate. The upper rotating shaft 24 drives the lower rotating shaft 24 to rotate through the pulley 22 and the connecting belt 23. The rotation of the two rotating shafts 24 drives several fixed cylinders 25 to rotate. The fixed cylinder 25 drives the knocking ball 29 to hit the fixed strip 26 on the filter cloth 8, so that the filter cloth 8 is vibrated. After the filter cloth 8 is vibrated, the impurities attached to the filter cloth 8 fall off. At the same time, the sliding column 28 slides in the fixed cylinder 25, and the spring 27 is compressed.

When the filter cloth 8 needs to be cleaned, the pressure pump 3 and the back-blowing pipe 4 can be used to blow air to clean the filter cloth 8. By setting the knocking assembly 2, when the back-blowing pipe 4 blows air to clean the filter cloth 8, the second motor 21 is turned on. The second motor 21 drives the upper rotating shaft 24 to rotate. The upper rotating shaft 24 drives the lower rotating shaft 24 to rotate through the pulley 22 and the connecting belt 23. The two rotating shafts 24 drive a plurality of fixed cylinders 25 to rotate. The fixed cylinders 25 drive the knocking balls 29 to hit the fixing strips 26 on the filter cloth 8, so that the filter cloth 8 is vibrated. After the filter cloth 8 is vibrated, the impurities attached to the filter cloth 8 fall off. At the same time, the sliding column 28 slides in the fixed cylinder 25, and the spring 27 is compressed. When the knocking ball 29 leaves the fixing strip 26, the spring 27 rebounds and pushes the sliding column 28 to reset. By setting the knocking assembly 2, the filter cloth 8 can be knocked and vibrated, and the cleaning effect on the filter cloth 8 is better.
