Development of chain-driving lever type machine for rape stalk dividing

The Chain-driving lever type machine was designed to resolve the problem of stalk dividing in rape harvesting, which had much difficulty in stalk dividing due to the across branches. Self-propelled walk chassis equipped with DC variable speed motor, while double power was used to achieve independent control of stalk dividing and walking. Then, acrylic material with arc-shaped structure was the critical working parts in stalk dividing, side expansion rollers were designed for sub-compartment forming. Tests showed that speed of 0.6m / s, angle of 60 ° -70 ° for driving lever obliquity, chain speed of 1.1 -1.2m/s, the effect of dividing stalk was better. It could achieve the stalk dividing operation for rape before mechanized harvesting.
