The mulching vinyl must be collected for the next crop season, but was left alone due to a shortage of labor. The used mulching vinyl that was left alone acted as one of the main sources of environmental pollution on farms. In order to solve these problems, a self-propelling vinyl remover was developed. The self-propelling vinyl remover consists of a travelling part and rotating of remover wheel. Each output device has a 1.5ps engine and a 2.5ps engine. The vinyl was twisted 17~47cm/times length. The bobbin's diameter was 160mm and it's stable travelling speed was 0.5m/s. The revolution of the remover wheel bobbin was 60rpm to maintain the wheel's linear velocity. As seen at performance test at the field which had 950mm ridge intervals and 10a area, the average working speed was 0.56m/s and the turning time was 15seconds. Therefore, the working performance was 40.1min/10a. Key Words : Vinyl Remover( ), Twist Wheel( ), Uplift Load( ), Self-Propelling Type( ) 1. 서론,,, * ** *** # : E-mail : kimtw@knu.ac.kr,,.. - 113 -
