Structural and technological analysis of working bodies of the machines for cleaning haulm

The analysis of technological process and working bodies of machines for cleaning are given. These machines are designed for cutting the main array of haulm and cleaning heads root crops from the remnants haulm. We have identified main general constructive flaws and have analyzed theoretical and experimental researches of working process of existing working bodies. Based on this improved construction of the machine for cleaning haulm for two-stage way of harvesting haulm are proposed.
