Design and experiments of a two-stage lift chain tapered shaft self-unloading residual film picker
The residue of waste film in the soil directly affects the emergence rate of seeds and the absorption and utilization of nutrients,while also causes great white pollution.The problem of picking up and recycling agricultural residual film has always been a persistent problem that troubles agricultural technicians and machinery personnel.The traditional drum,squirrel cage,and rake type residue film picking and recycling machines have unsatisfactory picking effects and low picking efficiency.In order to solve the problem of low residual film collection rate in traditional picking methods under the full film double ridge and ditch planting mode on the Loess Plateau,a two-stage lifting chain cone axis self-unloading residual film pickup machine is designed.The designed film scraper is used to achieve complete collection of residual film under the compacted soil,and a two-stage lifting chain mechanism is designed to screen and clean the soil blocks.The self-unloading mechanism is used to quickly release the film debris box,effectively reduce the intensity of manual work.The results indicate that the residual film pickup machine has excellent operational performance and is more suitable for the full film double ridge planting mode in the Loess Plateau.The two-stage lifting chain cone axis self-unloading residual film pickup machine has a stable residual film pickup rate of around 95％under various sowing modes.
