[0002] The agricultural machinery has more functions and can be used for fertilization, seeding, watering and the like, and can also be used for pesticide spraying and pest killing. During loading, the materials such as fertilizers, seeds and water are usually loaded into barrels and then sent to a high place, and then gravity is used for falling. The traditional loading method needs manpower to send the material barrels to a specified height, but this method consumes a lot of labor and has certain safety risks. The existing loading method mainly uses lifting equipment for loading.

[0003] For example, patent application No. CN201720383384.9 discloses an agricultural machinery vehicle-mounted lifting device. When loading is needed, the frame platform is laid down to the oblique front lower side. At this time, the platform is low in position, facilitating loading. After loading is completed, the platform is pulled up to the predetermined position by a hand winch, and the platform is fixed on the higher position of the agricultural machinery by the cooperation of the clamping groove and the clamping opening and the self-locking buckle.

[0004] The lifting method in the prior art still needs manpower to exert power, and the lifting is realized by the hand winch. However, when the weight of the material barrel is heavy, manpower cannot be used for lifting. In addition, during the lifting process, if the hand slips, a safety risk is easily caused.
