The pulverizing chamber (5) is located on one side of the transmission gear (602), and a fixed block (704) is fixedly connected to the bottom. The inner side of the fixed block (704) is rotatably connected. There are squeezing rollers (705), the bottom of which is in contact with the top of the second conveyor belt (702). 9. the control method of the automatic comprehensive separation and reuse system of municipal sewage as claimed in claim 8, is characterized in that: specifically comprises the following steps: S1: The municipal sewage is poured into the inside of the box (1) through the feeding hopper (2). After the sewage falls on the first conveyor belt (303), the water in the sewage passes through the leaking through holes on the surface of the first conveyor belt (303). 304) flow into the first water collecting box (305), and the garbage in the sewage remains on the surface of the first conveyor belt (303) to perform preliminary solid-liquid separation; S2: Turn on the servo motor (301) to drive the first rotating roller (302) to rotate, the first rotating roller (302) can drive the first conveyor belt (303) to transport the garbage on its surface, and the garbage passes through the pressing roller (306) When it is between the first conveyor belt (303), the pressing roller (306) squeezes the garbage to squeeze out the moisture, and then falls into the crushing chamber (5); S3: At the same time, the worm (3076) is driven to rotate by the adjusting handle (3077), and the worm (3076) drives the worm wheel (3075) on one side to rotate, so that the worm wheel (3075) can drive the rotating rod (3073) to rotate, so that the rotating rod (3073) It can drive the gear (3074) to rotate, the gear (3074) can drive the arc-shaped rack (3072) to rotate, and the arc-shaped rack (3072) drives the connecting frame (3071) to move in an arc-shaped motion on the box (1), thereby making the The position of the nip roller (306) changes, so that the distance between the nip roller (306) and the first conveyor belt (303) changes, so that the nip roller (306) and the first conveyor belt (303) are changed. The extrusion distance between them can be adjusted; S4: The servo motor (301) drives the second pulley (604) to rotate, the second pulley (604) drives the first pulley (603) to rotate through the belt (605), and the first pulley (603) drives two sets of crushing rollers (601) Rotate to cut the garbage falling into the crushing chamber (5), the cut garbage falls on the second conveyor belt (702), the driving motor (703) drives the second rotating roller (701) to rotate, and the second rotating roller ( 701) Drive the second conveyor belt (702) to rotate, when the cut garbage passes through the squeeze roller (705), the squeeze roller (705) squeezes the garbage again to squeeze out moisture, and then the moisture falls into the second water collecting box (706) ), while the waste is transported away from the box (1) by the second conveyor belt (702). 10. The control method for automatic comprehensive separation and reuse of municipal sewage according to claim 9, characterized in that: the surface of the box (1) is provided with a control panel, and the control panel is connected to a drive motor (703), a servo The motor (301) is electrically connected.
