in order to improve the picking efficiency of agricultural wastes such as straws, a mechanical picking mode is widely used, and a picker is used as an important component of a baler, and is used for picking up the agricultural wastes such as strawberries or straws scattered on the ground and conveying the agricultural wastes to a feeding end of the baler, so that mechanical picking and packing operations are realized. However, the conventional pickup has a high failure rate and a low pickup rate, and the reasons for this are as follows: the existing straw bundling machine is formed by transferring a pasture bundling machine, and the principles and the structures of the two machines are completely the same. Since most of the pasture grass is planted in a flat area of plain or sloping land, a pickup device in the pasture grass pickup operation does not contact with the ground surface, and crops such as corn and the like are usually planted on ridge platforms with height differences, which causes unevenness of the picked-up ground. When ridge culture farmland is picked up for operation, the elastic teeth of the pickup device can be in limited contact with the straws in the furrow only when being embedded into ridge soil. The pick-up device rotating at a high speed continuously carries out high-speed whipping on the straw cage platform and the soil on the ground surface, and sucks a large amount of soil (commonly called black soil) on the ground surface while picking up the straw, so that the problems of high soil content rate of grass and nutrient soil loss are caused, and in addition, the elastic teeth and the whole structure of the pick-up device can cause abnormal rapid abrasion due to non-standard use, so that the pick-up missing rate is high, and the energy consumption of equipment is increased; although the domestic grass baler imitation manufacturers also find the problems of high failure rate, difficulty in maintenance and the like, and adopt the shaftless horizontal elastic-tooth pickup to replace the traditional elastic-tooth pickup, the pickup principle is still the same, only at the cost of sacrificing the use function, the maintenance difficulty is reduced to a limited extent, but the problems of high equipment missing pickup rate and high grass bale soil containing rate still exist, and after the pickup is used for a period of time, the problem that the missing pickup rate is improved again due to the fact that the picked-up equipment is still seriously abraded due to the fact that the picked-up ground is uneven is solved, the defect caused by the fact that the flat ground pickup operation is transferred to ridge crop waste pickup is not really solved, and unnecessary use cost is brought to users.
