[0036] As a specific embodiment of this utility model:
[0037] Feces enter the machine body 1 through the feed hopper 11. The second motor 21 drives the conveying shaft 22 and the spiral blades 23 to rotate, conveying the feces from one end of the machine body 1 to the other. During the conveying process, the feces first pass through the filtration section 1-1. In the filtration section 1-1, the liquid in the feces falls into the liquid collection bin 14 through the filter screen 13, completing the first solid-liquid separation. The feces then pass through the drying section 1-2, where the electric heating element heats the heat-conducting plate 15, which performs preliminary drying of the feces and reduces the moisture content. Next, the feces fall into the collection box 40 through the discharge port 12. The control module is pre-set to start the second motor 21 for a certain period of time, then start the third motor 31 to squeeze the feces, and finally start the fourth motor 41 to push the material. The third motor 31 drives the hydraulic system. The extension and retraction of rod 32 causes the lower pressure plate 33, connecting rod 34, and upper pressure plate 35 to move down or up. After moving down, the lower pressure plate 33 squeezes the feces in the collection box 40, squeezing out the water from the feces and discharging it through the through hole, further reducing the moisture content. Then, the fourth motor 41 drives the push rod 42 to extend, pushing the squeezed feces out of the collection box 40 and into the hopper 51 of the shell 5, completing the second solid-liquid separation. Finally, the feces enter the shell 5 for crushing. The first motor 52 is started, causing the rotating shaft 53 to rotate and the blades 54 to break up and crush the feces. If there is still water, it is discharged from the filter plate 7. The top surface of the filter plate 7 is equipped with a heat-conducting plate 8, which is heated by an electric heating element. The heat-conducting plate 8 performs secondary drying of the feces, facilitating storage or subsequent processing of the feces.
[0038] During the process of crushing the feces inside the shell 5, the feces tend to stick to the inner wall of the shell 5. When the rotating shaft 53 rotates, it drives the horizontal bar 61 and the vertical bar 62 to rotate, which in turn drives the scraper 621 and the brush 622 to rotate along the inner wall of the shell 5 and scrape off the feces attached to the inner wall, thereby improving the processing efficiency.
