| Abstract: |
| In order to solve the problem of twining of potato vines that affected mechanized operations at harvest time, a flail potato vine cutting machine was designed. The shape, number, arrangement and movement of the flail, being the key component of the machine, were analyzed theoretically, and the structure and main parameters of the machine were determined. Furthermore, the prototype was used f
or field orthogonal experiment, in which the factors were flail speed, forward speed and blade type, and the indicators were percentage of uncut vines and power consumption. The experimental results showed that the optimal operating parameters of the machine were: flail speed: 1700 r·min-1; type of flail blades: Y-type; forward speed: 3.8 km·h-1. The working performance of the machine was stable and the percentage of uncut vines was 1%, meeting the technical design requirements and agronomic requirements. |
