A through opening is provided at the top of the degradation tank 1, and a fixed ring 2 matching the opening is hermetically arranged on the opening. A lifting ring 3 matching the inner wall of the fixed ring 2 is slidably arranged in the fixed ring 2. Scissor lifting mechanisms 4 are symmetrically arranged on both sides of the lifting ring 3. The upper end of the scissor lifting mechanism 4 is connected to the lifting ring 3, one side of the lower end of the scissor lifting mechanism 4 is hinged to the guide rod 7, the guide rod 7 is fixedly arranged on the degradation tank 1, and the other side of the lower end of the scissor lifting mechanism 4 is hinged to one end of the push-pull rod 6. The end of the push-pull rod 6 is slidably arranged in a chute on the guide rod 7, and the other end of the push-pull rod 6 is connected to the push-pull handle 5. The cross-sections of the fixed ring 2 and the lifting ring 3 are both circular and coaxially arranged. Among them, the degradation tank 1 is used to degrade feces. The fixed ring 2 and the lifting ring 3 are used in combination. The fixed ring 2 is fixed on the degradation tank 1, and the lifting ring 3 moves up and down under the action of the scissor lifting mechanism 4 in the prior art. After the lifting ring 3 moves up, it cooperates with the discharge port of the squat toilet, and feces enter the degradation tank 1 through the through hole in the lifting ring 3. There are two guide rods 7 symmetrically arranged, and two push-pull rods 6 are also arranged. The function of the push-pull handle 5 is to drive the push-pull rod 6 to move. The movement of the push-pull rod 6 drives the scissor lifting mechanism 4 to work. When the scissor lifting mechanism 4 works, it drives the lifting ring 3 to move up or down.

[0029] In some embodiments, it further comprises a stirring motor 8, a transmission shaft 9, a stirring shaft 10 and stirring blades 11. The transmission shaft 9 is arranged in a stirring groove 12 in the degradation tank 1. The stirring motor 8 is fixedly arranged outside the degradation tank 1 and is used to drive the transmission shaft 9 to rotate. A plurality of stirring shafts 10 are fixedly arranged on the transmission shaft 9, and stirring blades 11 matching the stirring groove 12 are fixedly arranged at one end of the stirring shaft 10. The transmission shaft 9 and the stirring shaft 10 are perpendicular to each other. Two stirring grooves 12 are symmetrically arranged on both sides of the discharge chute 14. Among them, the stirring motor 8 is a prior art. The function of the stirring motor 8 is to drive the transmission shaft 9 to rotate. The transmission shaft 9 drives the stirring shaft 10 and the stirring blades 11 to rotate. The stirring blades 11 fully stir the feces in the stirring groove 12, which facilitates the decomposition of feces by microorganisms. The transmission shaft 9 is arranged in both of the two stirring grooves 12, the stirring shaft 10 and the stirring blades 11 are arranged on the transmission shaft 9, and the two transmission shafts 9 are driven by gears.

[0030] In some embodiments, a reinforcing rib 13 is fixedly arranged on the stirring shaft 10. Among them, the arrangement of the reinforcing rib 13 makes the structure of the stirring shaft 10 stronger and prevents the stirring shaft 10 from breaking during the stirring process.

[0031] In some embodiments, a discharge chute 14 is fixedly arranged on the bottom of the degradation tank 1, and a discharge screw shaft 15 cooperating with the discharge chute 14 is arranged in the discharge chute 14. Among them, the arrangement of the discharge chute 14 and the discharge screw shaft 15 in the prior art facilitates discharging the decomposed feces from the degradation tank 1. A discharge port is arranged on the degradation tank 1, and the discharge port cooperates with the output end of the discharge screw shaft 15, and the discharge port is in a closed state when not discharging.

[0032] In some embodiments, the stirring motor 8 is connected to the transmission shaft 9 through a first transmission chain 16, and the transmission shaft 9 is connected to the discharge screw shaft 15 through a second transmission chain 17. Among them, sprockets are arranged on the stirring motor 8, the transmission shaft 9 and the discharge screw shaft 15, and the use of the first transmission chain 16 and the second transmission chain 17 for transmission makes the transmission smoother. As Figure 3 shown, a single stirring motor 8 drives the discharge screw shaft 15 and the transmission shaft 9 to work simultaneously, which can reduce the manufacturing cost of the equipment.

[0033] In some embodiments, lubricating oil pipes 19 are arranged in cooperation with the first transmission chain 16 and the second transmission chain 17. The input end of the lubricating oil pipe 19 is communicated with a lubricating oil pump 18, and the lubricating oil pump 18 is fixedly arranged on the degradation tank 1. Among them, the arrangement of the lubricating oil pump 18 and the lubricating oil pipes 19 can better lubricate the first transmission chain 16 and the second transmission chain 17 and reduce the wear of the equipment.

[0034] In some embodiments, the discharge screw shaft 15 is connected to a discharge motor 20, the discharge motor 20 is fixedly arranged on the degradation tank 1, and a baffle 21 cooperating with the discharge screw shaft 15 is slidably arranged on the discharge chute 14. As Figure 5 shown, the stirring motor 8 only drives the transmission shaft 9 to rotate for stirring work, while the discharge screw shaft 15 is independently driven by a discharge motor 20 in the prior art and only works when discharging is required, which plays an energy-saving role. The baffle 21 can be pulled and slid in the degradation tank 1, and grooves cooperating with both sides of the baffle 21 are arranged on both sides of the discharge chute 14. The baffle 21 is only opened when discharging. After the baffle 21 is opened by pulling outside the degradation tank 1, the decomposed feces enter the discharge chute 14 and are then discharged by driving of the discharge screw shaft 15.
