Development and research of tillage operating device with polymeric materials

Polymeric materials are advised to be used in the construction of operating devices for energy-saving soil cultivation. Purpose of work is to develop the design of new operating devices with polymer materials. Development of the design of new operating devices with polymeric materials is carried out by replacing part of the metal parts with ultra-high molecular polyethylene of low density. New operating devices carry out several technological operations in one pass. The design of the new operating device contains a rack with a chisel for deep tillage. The front of the rack is equipped with removable plowshare blades. Clod crusher with a possibility of movement and thrust plate are located at the chisel. In the upper part of the rack the ripper for surface tillage is mounted with the possibility of replacing. Ultra-high molecular polyethylene of low-density was installed on the chisel and clod crusher of the tillage operating device, the thrust plate and the ripper for surface tillage are made entirely of polymeric material. Decrease to 18.28% of draught resistance of the operating device with polymeric materials was established.
