[0002] In agricultural production, mulching technology is widely used in various crop cultivation, significantly improving crop yields and quality. However, if mulch films are not promptly recovered after use, the remaining film in the soil can cause soil compaction, hinder crop root growth, and affect water and nutrient transport, leading to reduced crop yields and causing serious pollution to the ecological environment.

[0003] The distance between the picking parts of traditional residual film pickers and the ground is difficult to adjust in real time according to terrain changes. It lacks a flexible adaptive adjustment mechanism and is difficult to meet diverse operational needs. The picking parts are prone to collision and damage with the ground, or the residual film is not picked up thoroughly due to being too high from the ground, which limits its application in farmland with complex terrain.

[0008] Furthermore, the floating assembly includes a supporting shaft and a fixed shaft, and the supporting shaft and the fixed shaft are arranged parallel to the inner wall of the frame. A swing arm is provided on the supporting shaft for damping rotation. The floating wheel is connected and rotated at the end of the swing arm through an axis, and a spring rod is hinged on the fixed shaft, the end of which is hinged to the swing arm.

[0009] Furthermore, the buffer assembly includes a push groove and a push block, the push grooves are opened on both side walls of the buffer groove, the push blocks are slidably arranged in the push grooves, a movable shaft is provided between the two groups of push blocks, the buffer wheel is rotatably arranged on the movable shaft, a buffer spring is provided between the push block and one end side wall of the push groove, and the buffer spring is arranged away from the floating wheel.

[0010] Preferably, a mounting block is provided on the support plate.

[0011] The present invention adopts the above structure to achieve the following beneficial effects:

[0012] 1. By setting the swing arm and spring rod, the floating wheel can change its height according to the terrain. With the help of the buffer spring and push block, the buffer wheel is supported and pushed, so that the drive belt can always keep the tension state. The drive roller and transmission groove drive the drive belt to realize the rotation of the drive belt. The spikes are used to pick up the residual film to meet the use requirements of different terrains.
