全膜双垄沟旋齿式残膜回收机设计与试验
Design and Experiment of Rotary-tooth Residual Film Recycling Machine with Whole Film Double Ridges and Furrows
摘要
Abstract
After the harvest of full-film double-ridge furrow planting technology in Gansu,the surfaces and furrows of the large ridges are covered with compacted soil layers.The high stubble height leads to the interweaving of corn stubble,fibrous roots and plastic film in the furrows,resulting in incomplete recovery of residual film.This not only causes soil environmental pollution but also affects crop root growth and the transport of water and nutrients.Traditional models under such working conditions have problems,including high impurity content,easy plastic film entanglement,prone to soil accumulation,and incomplete recovery of plastic film in furrows.Based on the principle of the reel,a rotary-tooth residual film recovery machine for full-film double-ridge furrows was designed,realizing continuous lifting,directional transportation and separation of residual film from impurities.Combined with the planting agronomy of the full-film double-ridge furrow planting technology and the residual film recovery working conditions,the overall structure and key component parameters of the machine were determined.Through theoretical calculations and numerical analysis,key components such as the film-picking device,film conveying device,film rolling device,and film-impurity side output device were analyzed and parameterized.According to the Box-Behnken experimental design principle,a three-factor three-level response surface methodology was adopted to optimize the operating parameters of the machine,and the optimization results were verified through experiments.The results showed that the optimal parameters were a machine forward speed of 1.5 m/s,a film-picking depth of 105 mm,and a film-picking rotational speed of 15 rad/s,with a residual film recovery rate of 93.3%.关键词
