Design and test on double-roller sweet potato vine crushing and returning machine

At present, all most sweet potato crushing machineries are improved based on potato seedling killer or straw crushing and returning the machine and adopt single-roller mulch type seedling killing structure, and there are problems such as low crushing qualification rate of ridge vines, easy entanglem...

To solve the problems, a double-roller sweet potato vine crushing and returning machine with the structure of the front roller picking and the back roller crushing was designed.
