| Abstract: |
| To improve the mechanization level of film residue recovery in cotton field in Xinjiang and solve the problems of low film residue recovery rate and high impurity rate of machine tools, this study designed an integrated machine for film residue recovery and straw returning to field. According to the planting mode and field operation requirements of Xinjiang cotton, the key parts of the whole machine were redesigned. The parameters of the spinner type crushing knife and the skein speed was 1 500 r·min-1. The rotary radius of the film picking drum was 245 mm, and the rotary radius of the template stripping was 278.5 mm. The moving speed of the machine tool, the depth of the pick\|up film teeth in the soil and the rotation speed of the output shaft were selected as the influencing factors, and the recovery rate of the remnant film and the impurity content rate were taken as the test indexes. The design\|expert 8.0.6.1 software was used to carry out three\|factor three\|level orthogonal experiment design. The optimum parameters were determined as follows: the forward speed of the machine tool was 7 km·h-1, the depth of the collecting film teeth into the soil was 25 mm, and the rotation speed of the output shaft was 760 r·min-1. The experimental results showed that under the optimal parameters, the average recovery of residual film was 85.03%, the average impurity content was 15.88%, and the comparison error with theoretical value was less than 3%. The model was reliable. The research results met the requirements of the field operation of the residual film recovery machine. |
