[0032] In the initial state, a large gap is left between several groups of arc plates 816 to facilitate sewage to enter, the elastic member 815 is in a stretched state, and the threaded sleeve 812 is located at the bottom of the thread groove; the driving member 3 drives the driving rod 4 to rotate, the driving rod 4 drives the sliding rod 5 to rotate, the limiting rod 74 drives the threaded sleeve 812 to rotate, and the rotation direction of the sliding rod 5 is opposite to the rotation direction of the threaded sleeve 812.

[0033] As an embodiment of the present invention, please refer to Figure 2 , Figure 3 , Figures 7 to 9 , the side pressure assembly 82 includes: A connecting plate 821 connected to the arc plate 816; A connecting rod 822 connected to the connecting plate 821; The rotating cylinder 823 is rotatably connected to the connecting rod 822; The spiral spring 824 is disposed inside the rotating cylinder 823, and one end of the spiral spring 824 is connected to the rotating cylinder 823, and the other end of the spiral spring 824 is connected to the connecting rod 822; The water pressure plate 825 is connected to the rotating cylinder 823; The power assembly 826 has one end connected to the connecting plate 821 and the other end connected to the sliding rod 5 .

[0034] The sliding rod 5 drives the power component 826 to move, and the power component 826 drives the water pressure plate 825 to rotate around the connecting rod 822. The two sets of relative water pressure plates 825 drive the sewage to move, so that the sewage impacts each other and improves the stirring effect. The setting of the spiral spring 824 ensures that the water pressure plate 825 can return to the original position.

[0038] The threaded sleeve 812 drives the sliding folding rod 811 to move upward, and the sliding folding rod 811 drives the sensing piece 1 831 to move upward. When the threaded sleeve 812 cannot continue to move, the sensing piece 1 831 contacts the sensing piece 3 833 and transmits the signal to the controller (not shown in the figure). The controller controls the telescopic piece 6 to work and drives the sliding rod 5 to move upward, so that the sewage between the several groups of arc plates 816 is lifted upward. When the threaded sleeve 812 drives the sliding folding rod 811 to move downward and the threaded sleeve 812 cannot continue to move, the sensing piece 1 831 contacts the sensing piece 2 832 and transmits the signal to the controller. The controller controls the telescopic piece 6 to work and drives the sliding rod 5 to move downward.

[0039] The working principle of the present invention is as follows: in the initial state, a large gap is left between the plurality of arc plates 816, the elastic member 815 is in a stretched state, and the threaded sleeve 812 is located at the bottom of the threaded groove; Pour sewage and medicine into the housing 1, the driving member 3 drives the driving rod 4 to rotate, the driving rod 4 drives the sliding rod 5 to rotate, the driving rod 4 drives the gear 1 751 to rotate, the gear 1 751 drives the gear 2 752 to rotate, the gear 2 752 drives the gear ring 754 to rotate, the gear ring 754 drives the limit rod 74 to rotate, the limit rod 74 drives the connecting sleeve 72 to revolve, the connecting sleeve 72 drives the stirring rod 73 to rotate, and the sewage and medicine are stirred; At the same time, the connecting sleeve 72 drives the sliding folding rod 811 to rotate, and the sliding folding rod 811 drives the threaded sleeve 812 to rotate, and the rotation direction of the sliding rod 5 is opposite to the rotation direction of the threaded sleeve 812. Under the force provided by the elastic member 815, the threaded sleeve 812 is threadedly connected with the thread groove, so that the threaded sleeve 812 drives the sliding folding rod 811 to move upward, the threaded sleeve 812 drives the support rod 814 to move, and the support rod 814 drives the arc plate 816 to rotate, so that the groups of arc plates 816 are close to each other, the gap is reduced, and the sliding folding rod 811 is connected to the threaded sleeve 812. The rod 811 drives the induction member 1 831 to move upward synchronously. When the threaded sleeve 812 moves to be separated from the threaded groove, the threaded sleeve 812 cannot continue to move upward, the elastic member 815 is in a compressed state, the induction member 1 831 contacts the induction member 3 833, and transmits a signal to the controller (not shown in the figure). The controller controls the telescopic member 6 to work, driving the sliding rod 5 to move upward, so that the sewage between the several groups of arc plates 816 is lifted upward, thereby lifting the bottom sewage to the top, ensuring that the sewage and the reagent are evenly mixed; After the bottom sewage is lifted, the driving member 3 rotates in the opposite direction, and under the reaction force of the elastic member 815, the threaded sleeve 812 is threadedly connected with the threaded groove again, so that the threaded sleeve 812 drives the support rod 1 814 to move, so that the arc plate 816 rotates and returns to the initial position; The sliding rod 5 drives the fan-shaped plate 8261 to rotate, and the arc plate 816 drives the fixed rod 8264 to rotate, and the fan-shaped plate 8261 and the fixed rod 8264 rotate in opposite directions. When the fan-shaped plate 8261 contacts the fixed rod 8264, the fixed rod 8264 is squeezed and moves upward, driving the second support rod 8263 to move, and the second support rod 8263 drives the sliding block 8262 to move, and the sliding block 8262 drives the roller 8266 to move, thereby squeezing the water pressure plate 825, so that the two groups of water pressure plates 825 move relative to each other, so that the sewage impacts each other, thereby improving the stirring and mixing effect.
