Analysis and Test of the Tillage Layer Roll-Type Residual Film Recovery Mechanism

Abstract

With the extensive use of plastic film mulching in planting, the amount of residual plastic film in soil has been increasing, causing soil and water pollution, harming crop growth, and reducing agricultural product quality and yield. In response to this issue, this study proposes a roll-type residual film recovery mechanism using the tillage layer method. The structure and operation principles of this system are discussed, and a detailed analysis of its key components and working process is provided. The lifting cutter operates at a speed of 22.37 rad/s, the pick-up drum at 4.58 rad/s, the roll forward rotation picks up the film at 13.74 rad/s, and the roll reverse film rotation unloads the film at 17.57 rad/s, with the unloading wheel rotating at a speed of 4.5 rad/s. ADAMS (software of automatic dynamic analysis of mechanical systems) Version No.2019 is used for modeling and analysis, and the displacement and velocity change patterns of MARKER_499, MARKER_500, and MARKER_505, which are marked points of the spring-tooth tips and are found to be the same. The maximum resultant displacement of MARKER_499 and MARKER_500 is 22.146 mm when picking up plastic film and 17.047 mm when unloading plastic film. Meanwhile, the maximum resultant displacement of MARKER_500 and MARKER_505 is 231.715 mm in the film-picking area and 234.028 mm in the film-unloading area. After analyzing the velocity of MARKER_499 during picking and unloading of the film, it was determined that the absolute velocity for the picking direction was 79,809.407 mm/s, and for the unloading direction it was 10,2266.168 mm/s. Bench tests show a tillage gathering rate of 71.6% and a surface gathering rate of 83.4%, meeting the performance requirements of the roller-type residual film recovery mechanism. These findings provide a theoretical basis for the design of the structure and operational parameters for the roll-type residual film recovery mechanism using the tillage layer method.

YOLOv5-Atn: An Algorithm for Residual Film Detection in Farmland Combined with an Attention Mechanism

“…Mechanical recycling can effectively overcome the disadvantages of manual recycling, improve labor productivity and the residual film collection rate, and meet the requirements for discarded mulching film recycling [ 6 ]. In recent years, researchers have developed many forms of residual film recycling machines [ 7 , 8 , 9 , 10 ], but residual film recycling machines are almost useless for small sizes of film. In view of the shortcomings of the existing residual film recycling machines, this paper proposes the use of target detection technology to identify and locate residual film to provide a theoretical basis for the realization of the development of an intelligent residual film picking machine.…”

“…Contemporary methods of mechanized recycling of residual film have shown good results, and different types of film recovery machinery have emerged, as shown in Figure 2. Shi et al [3] propose a roll-type residual film recovery mechanism using the tillage layer method. The structure and operation principles of this system are discussed, and a detailed analysis of its key components and working process is provided.…”
