Through slope filter screen 9's setting, can carry out filtration treatment to the waste water after spraying, the purpose of circulating water has been realized, resources are saved, when starting driving motor 17, can drive motor shaft 18 and rotate, and then two transmission helical gears 25 of accessible drive clean pivot 20 and rotate, clean pivot 20 rotates and can drive clean scraper blade 23 through fixed plate 21 and activity slide bar 22 and rotate, thereby realized can carrying out self-cleaning to slope filter screen 9 and handled the purpose, and simultaneously, under extrusion spring 24's spring action, can extrude to promote clean scraper blade 23 and hug closely slope filter screen 9 always and carry out cleaning treatment, clean effect is better, effectively reduce the condition that slope filter screen 9 appears being blockked up, the practicality is good.
When the motor rotating shaft 18 rotates, the control rotating shaft 26 can be driven to synchronously rotate through the driving belt wheel 33 and the driving belt 34, the control rotating shaft 26 rotates to drive the notch gear 31 to rotate, when the notch gear 31 rotates to be meshed with the linkage rack 30, the notch gear 31 rotates to drive the linkage rack 30 to move downwards, then the hexagonal slide bar 28 can drive the knocking block 29 to be far away from the inclined filter screen 9, meanwhile, the knocking spring 32 can be compressed, when the notch gear 31 rotates to be separated from the linkage rack 30, under the elastic action of the knocking spring 32, the knocking block 29 can be pushed to automatically reset and knock on the inclined filter screen 9 through extrusion, particle impurities blocked in meshes of the inclined filter screen 9 can be ejected, and the anti-blocking effect is better.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
