[0032] Working principle and technical effects of the present invention: First, the bag opening 602 of the feeding bag 6 and the tank cover 105 are matched and connected to each other, that is, the threaded joint 106 is threadedly connected to the threaded connection hole 603, and the push rod of the handle structure 3 is extended to increase the distance between the end rod 302 and the mixing tank 1, and the third motor 703 of the rope assembly 7 drives the rope drum 702 to rotate, and the rope drum 702 rotates to loosen the pull rope 707, and the hook 708 extends from the mixing tank 1. The hook 708 and the hanging ring 601 are hung with each other, and then the third motor 703 of the rope assembly 7 drives the rope drum 702 to rotate in the opposite direction, and the feeding bag 6 is pulled into the mixing tank 1 until the tank cover 105 and the inner convex ring 107 abut against each other, and the sealing gasket 108 realizes the sealing of the abutment; The output shaft of the first motor 104 rotates, driving the mixing tank 1 to flip up and down relative to the handle structure 3, thereby realizing that the bag opening 602 of the feeding bag 6 faces upward, and the injection plug structure 5 can be used to stably insert the feeding bag 6, thereby realizing the addition of nutrient solution into the feeding bag 6. After the addition is completed, the injection plug structure 5 and the feeding bag 6 are separated from each other; When various nutrient solutions in the feeding bag 6 are mixed and dissolved, at this time, the first motor 104 drives the mixing tank 1 to flip up and down, and then the rotation drive component 2 drives the extruding wheel 8 to rotate along the outside of the feeding bag 6.

The long axis direction of the extruding wheel 8 is inclined to the long axis direction of the feeding bag 6, that is, one of the extruding wheels 8 squeezes the liquid in the feeding bag 6 to flow upward, and the other extruding wheel 8 squeezes the liquid in the feeding bag 6 to flow downward, thereby realizing the up and down circulation of the liquid in the feeding bag 6, and realizing the full mixing and dissolution of the nutrient solution inside the feeding bag 6. When the nutrient solution in the feeding bag 6 is discharged, the bag mouth 602 of the feeding bag 6 faces downward, and the external needle tube is inserted and discharged. In this process, the air pressure of the sealed chamber can be adjusted by the first air pump 102 and the second air pump 103, thereby adjusting the nutrient supply speed by controlling the deformation of the feeding bag 6.
