The cylinder 28 is connected to the push rod 29, and the push rod 29 is connected to the round hole connector 30; the multi-functional medicine water tank 41 is placed in the medicine water pool 42. A faucet 43 is installed on the outer wall of the medicine water pool 42, and a wastewater treatment tank 2 is provided below the faucet 43.

[0037] A connecting device slide plate 50 and a stacking lifting device 54 are provided between the conveying device 1 and the soaking device 55. The slide plate 50 has a certain inclination angle, which is beneficial for the fruits and vegetables after cleaning and drying to enter the soaking process. The function of the stacking lifting device 54 is that when the multi-functional medicine water tank 41 is filled with fruits and vegetables, the air cylinder 26 drives the lifting baffle 27 to descend, close to the slide plate 50 to block the continuous sliding of the fruits and vegetables; when a certain number of fruits and vegetables are blocked, the air cylinder 26 drives the lifting baffle 27 to rise, away from the slide plate 50, so that the fruits and vegetables fall into the multi-functional medicine water tank 41 to continue the next soaking operation.

[0038] During use, first, the air cylinder 25 pushes the push rod 29 to rise, and then the lifting baffle 27 also rises accordingly. At this time, the fruits and vegetables can slowly roll down through the slide plate 50 into the multi-functional medicine water tank 41. When the multi-functional medicine water tank 41 is filled with fruits and vegetables, the air cylinder 25 descends to drive the lifting baffle 27 to descend, thereby blocking the fruits and vegetables transported from the conveying device 1. When the multi-functional medicine water tank 41 can continue to load fruits and vegetables, repeating the above actions can complete the pretreatment process of the fruit and vegetable soaking process. The fruits and vegetables are transported from the stacking lifting device 54 into the multi-functional medicine water tank 41, and then soaked in the medicine water tank 4 for 3 minutes. The chemical components and dosage of the preservative in the medicine water tank 42 are mainly 5% acetic acid aqueous solution of maleopimaric anhydride modified chitosan 200 - 800 μg / mL, Tween 80 0.002 - 0.01 μL / mL, and glycerol 0.002 - 0.01 μL / mL.

[0039] The disc transport device 51 includes a disc transport device base 36, a rotating disc 39, a screw 38, an auxiliary cylindrical support device 35, a ball lifting plate 37 and a transport claw 34; the disc transport device base 36 is installed on the upper part of the bottom plate 45, the rotating disc 39 is on the upper part of the disc transport device base 36, and a ball screw device 56 is installed inside the rotating disc 39. The ball screw device 56 includes a screw 38, a ball lifting plate 37, an auxiliary cylindrical support device 35 and a transport claw 34, and the ball lifting plate 37 performs up and down translational motion on the screw 38 and the auxiliary cylindrical support device 35. In specific use, when the multifunctional medicine box 41 is full of fruits and vegetables, the ball screw device 56 in the disc transport device 51 will lift the multifunctional medicine box 41 up, and then start to rotate after reaching a certain height, and transport the fruits and vegetables that have been soaked for 3 minutes to the workbench 47. During the transportation process, the residual medicine on the fruits and vegetables will drip onto the ground due to gravity. In order to avoid such waste, a medicine recovery device 44 is installed around the disc transport device 51, so that the medicine dripping during the transportation process can be recycled and reused, saving costs; at the same time, during the transportation of fruits and vegetables, the fruits and vegetables on the slide plate 50 will be blocked by the lifting baffle 27 to prevent the fruits and vegetables from rolling directly into the medicine pool 42; when the multifunctional medicine box 41 filled with fruits and vegetables reaches the top of the workbench 47, the cylinder in the multifunctional medicine box 41 will push the push rod 29 to move downward, and the end of the push rod 29 is connected to the round hole connector 30 by an iron chain, and the hinge plate 31 and hinge plate 32 is a hinge connection, so it has a relative rotation effect, so when the push rod 29 moves downward, the hinge plate 32 will open, and the fruits and vegetables will slowly fall to the workbench 47 for the subsequent drying and classification. In the process of the fruits and vegetables falling to the workbench 47, the multifunctional medicine box 41 at the other end of the disc transport device 51 falls into the medicine pool 42. At this moment, the lifting baffle 27 rises, and the fruits and vegetables roll into the multifunctional medicine box 41 with the slide plate 50 and begin to soak. When the fruits and vegetables at one end of the workbench 47 are unloaded, the fruits and vegetables at the other end are soaked for just 3 minutes. The above steps are repeated in a cycle to efficiently complete the fruit and vegetable transport work, and the surface of the fruits and vegetables is efficiently coated with the preservative and quickly dried to form a preservative film.

[0040] A medicine recovery device 44 is installed on the path taken by the multifunctional medicine box 41 as it rotates with the disc transport device 51. The medicine recovery device 44 can effectively recover the medicine dripping from the multifunctional medicine box 41 during movement, and then recycle it through the medicine recovery tank 3.
