The disinfection and sterilization ultraviolet lamp 823 inside the U-shaped mounting plate 821 pre-disinfects the filling area. The preservation liquid in the liquid storage tank 3 is sucked into the transfer pipeline 824 by the transfer pump and transmitted to the connection box 826 through the telescopic hose 825. At this time, the electric telescopic rod 827 extends or retracts according to the instructions of the controller 7, driving the connection box 826 and the filling head 828 to accurately move above the clamped large fruits. The filling head 828 ensures sealed contact with the filling bottle through the sealing ring 829 around it, and then starts the filling operation. Finally, after the filling head 828 accurately and appropriately injects the preservation liquid into the filling bottle, the electric telescopic rod 827 drives the filling head 828 to reset, thus completing the work of filling the preservation liquid.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
