The movement of the connecting shaft drives the anti-stick strip to be reciprocatedly pulled out of the storage shaft.

[0015] The present invention provides an automatic excrement cleaning device for broiler chickens in the whole antibiotic-free breeding process. It has the following beneficial effects:

[0016] (1) In this invention, by setting up a manure scraping device, the manure produced by the chicken coop will fall onto the conveyor belt. The rotation of the rotating motor drives the A conveyor roller to rotate and drives the conveyor belt to transport the manure. The A conveyor roller rotates in coordination with the B conveyor roller and the eccentric rotating rod so that the A scraper can scrape the manure stuck on the conveyor belt to prevent the manure from sticking to the conveyor belt and affecting the conveying environment. The B conveyor roller rotates in coordination with the screw rod to drive the moving blocks on both sides to move back and forth toward the center of the conveyor belt through the spiral grooves opened on the left and right, so as to push the manure on both sides of the conveyor belt to the center of the conveyor belt, so that the manure can be processed in a centralized manner and the manure plates can be prevented from sticking to the gaps on both sides of the conveyor belt, causing the conveyor belt to be blocked and making the conveyor belt unable to work.

[0017] (2) In the present invention, by setting up the screening device, the feces will fall onto the top of the filter plate. At this time, the rotating motor rotates to drive the reciprocating rod to rotate through the spiral groove to drive the moving rod to move back and forth. The movement of the moving rod drives the roller to rotate, so as to squeeze the feces plate back and forth, so that the squeezed water is transported to the drainage plate through the filter plate for discharge. The feces are separated into solid and liquid, and a purer liquid part can be obtained, which can be used as liquid fertilizer or for subsequent treatment. At the same time, solid waste can be more conveniently handled, such as used as solid fertilizer or for other reuse or disposal. At the same time, the rotation of the A rotating rod drives the B rotating rod to move back and forth, so that the filter plate moves back and forth and cooperates with the spring sheet to make the filter net move back and forth quickly and shake, so that the solid feces are transported to the protective plate through shaking and gravity.

[0018] (3) In the present invention, by setting up the squeezing device, the reciprocating rod rotates through the No. 2 belt to drive the rotating wheel to rotate, and the rotation of the rotating wheel drives the C rotating rod to move forward and backward. The movement of the C rotating rod drives the dung plate to slide on the inner wall of the protective shell, so that the dung is transported to the protective plate. The movement of the dung plate drives the movement of the connecting rod. The movement of the connecting rod drives the rolling block to move forward and backward, and cooperates with the auxiliary plate to squeeze the dung. By squeezing the chicken manure, it can be compacted to reduce the volume and weight, which helps to save space and cost during storage, transportation and processing.

[0019] (4) In the invention, the anti-splash device is set up. The movement of the rolling block drives the connection shaft to move. The movement of the connection shaft drives the anti-sticking strip to be reciprocated and withdrawn from the storage shaft. When the feces are squeezed, the feces may splash out from the protective plate. At this time, the splashing feces is blocked by the anti-sticking strip to prevent the splashing feces from polluting the surrounding environment and increasing the risk of infectious diseases. When the anti-sticking strip is retracted, the feces on the surface of the anti-sticking strip can be scraped off by the scraping strip, thereby realizing automatic cleaning of the anti-sticking strip and preventing the anti-sticking strip from being blocked due to the accumulation of feces on the surface.
