The sliding block 31 screwed on the threaded rod 29 can only move in the vertical direction on the second limit rod 34, so that when the threaded rod 29 rotates, the sliding block 31 only moves in the vertical direction and cannot rotate along with the threaded rod.
In the preferred technical scheme of this embodiment, a magnet 35 is fixedly mounted at the top end of the sliding rod 21, and the second hollow tube 10 is made of a magnetic material. When the scraping strips 22 move vertically along with the sliding rod 21 and abut against the surface of the filter screen 4, at this time, the magnet 35 fixedly installed at the top end of the sliding rod 21 abuts against and adsorbs the bottom end of the second hollow tube 10, even in the process of cleaning the surface of the filter screen 4 by sliding the scraping strips 22, the impurities attached to the surface of the filter screen 4 are reduced, the wind force acting on the two pieces of gauze 23 through the filter screen 4 is increased, the degree of bending deformation of the gauze 23 is increased, but because the magnetic force adsorbed between the magnet 35 and the second hollow tube 10 can counteract a part of the suddenly increased wind pressure, the two pieces of gauze 23 which are subjected to bending deformation can not directly drive the sliding rod 21 to move downwards, the end part of the sliding rod 21 can abut against the end part of the second hollow tube 10 at this time, and the scraping strips 22 can be driven to continuously rotate for a period of time and then stop without increasing the wind pressure, the end of the sliding rod 21 will leave the end of the second hollow tube 10 and further drive the scraping strip 22 to leave the surface of the filter screen 4, and stop the cleaning work of the surface of the filter screen 4, only when the scraping strip 22 cleans impurities on the surface of the filter screen 4 almost quickly, and at this time, when the wind force acting on the two gauzes 23 through the filter screen 4 reaches a certain degree, the wind pressure generated on the surface of the gauzes 23 at this time is enough to offset the magnetic force absorbed between the magnet 35 and the second hollow tube 10, so that the sliding rod 21 will drive the scraping strips 22 fixedly connected with the surface to move down and leave the surface of the filter screen 4.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
