[0021] S1: First, extend the bellows into the sewage in the sewage ditch, and use the liquid pump to pump the sewage generated by the poultry in the sewage ditch into the barrel body. The driving motor drives the pulley and the belt to rotate, and the rotation of the pulley drives the spline sleeve to rotate, and the rotation of the spline sleeve drives the rotating rod to rotate, and the rotation of the rotating rod drives the boss and the piston disc to rotate, and the rotation of the piston disc drives the four water outlet pipes to rotate, and the rotation of the four water outlet pipes drives the four L-shaped sleeves to rotate, and the rotation of the four L-shaped sleeves drives the suction cylinders and the four sleeve rings to rotate, and the rotation of the suction cylinder drives the turntable and the stirring rod to rotate horizontally, and the rotation of the sleeve drives the four L-shaped rods to rotate. Due to the setting of the circular ring and the inclined groove, the L-shaped rod will also move up and down when rotating, and the up and down movement of the L-shaped rod drives the sleeve ring to move up and down, and the up and down movement of the sleeve ring drives the first connecting rod and the L-shaped sleeve to move, and the movement of the first connecting rod drives the top turntable to reciprocate, and the top turntable drives another turntable to reciprocate through the second connecting rod, and the reciprocating rotation of the turntable drives the stirring rod to reciprocate and rotate, so as to achieve mixing of the poultry sewage inside the barrel body;

The rotation of the piston plate (25) drives the four water outlet pipes (26). The rotation of the four water outlet pipes (26) drives the four L-shaped sleeves (16). The rotation of the four L-shaped sleeves (16) drives the suction cylinder (9) and the four sleeve rings (15) to rotate. The rotation of the suction cylinder (9) drives the rotating disk (12) and the stirring rod (1 1) horizontal rotation, the ring (15) rotates to drive the four L-shaped rods (22) to rotate, due to the arrangement of the circular ring (18) and the inclined groove (21), the L-shaped rod (22) will also move up and down during the rotation, the up and down movement of the L-shaped rod (22) drives the ring (15) to move up and down, the up and down movement of the ring (15) drives the first connecting rod (13) and the L-shaped sleeve (16) to move, the movement of the first connecting rod (13) drives the top turntable (12) to reciprocate, the top turntable (12) drives the other turntables (12) to reciprocate through the second connecting rod (14), the reciprocating rotation of the turntable (12) drives the stirring rod (11) to reciprocate, so as to achieve mixing of the poultry sewage inside the barrel (1); S2: Due to the arrangement of the connecting groove (29), the boss (30) will also move up and down when it rotates. The up and down movement of the boss (30) drives the rotating rod (3) to move up and down, and the up and down movement of the rotating rod (3) drives the piston plate (25) to move up and down. When the piston plate (25) moves upward, the second one-way valve (27) is closed and the first one-way valve (20) is opened, so that the poultry sewage at the bottom of the barrel body (1) enters the interior of the suction cylinder (9) from the water inlet pipe (19). When the piston plate (25) moves downward, the second one-way valve (27) is opened and the first one-way valve (20) is closed, so that the poultry sewage inside the suction cylinder (9) will be discharged from the water outlet pipe (26) through the horizontal side of the L-shaped sleeve (16) to the upper part of the poultry sewage inside the barrel body (1), so as to achieve the flow mixing of the poultry sewage inside the barrel body (1), thereby ensuring the accuracy of the result of the poultry sewage detection; S3: After the poultry sewage in the barrel body (1) is mixed, the hollow tube (17) is driven to move downward by the electric telescopic rod (2). When the hollow tube (17) contacts the poultry sewage, the poultry sewage enters the hollow tube (17). Finally, the two baffles (10) seal both ends of the hollow tube (17) to keep the poultry sewage in the hollow tube (17) in a static state. The poultry sewage in the hollow tube (17) can then be detected by the detection head.
