摘要：
The invention relates to agricultural machinery, in particular to a system for cleaning grain heaps of a combine harvester, the drive mechanism of which provides reciprocating movement of the working bodies. The aim of the invention is to simplify the design, reduce dynamic loads in the drive and increase reliability by reducing the inertial forces of oscillating working bodies. This goal is achieved by the fact that in the cleaning system of the combine harvester, comprising a frame, upper and lower sieve mills mounted on top of each other and a shaking board, interconnected by at least two two-arm levers and two recuperators, a drive, according to the invention, recuperators, each of which made in the form of a cylindrical tension-compression spring, installed so that one end of the spring is connected through the hinge to the upper end of the two shoulders of the lever, the other end of the spring is connected through the hinge to the bracket with the shaking board. The proposed cleaning design provides a simplification of the mechanism by eliminating the levers of the damper and allows you to accumulate and give energy to the cleaning drive, which provides oscillatory movement of the shaking board, the upper and lower sieve mill. Reducing the weight of the heat exchanger and connecting the heat exchanger to the shaker board and the upper sieve mill can reduce the dynamic loads on the frame of the combine, reduce the energy consumption of the drive and increase reliability.Изобретение относится к сельскохозяйственному машиностроению, в частности к системе очистки зернового вороха зерноуборочного комбайна, механизм привода которого обеспечивает возвратно-поступательное движение рабочих органов. Целью изобретения является упрощение конструкции, снижение динамических нагрузок в приводе и повышение надежности путем снижения инерционных сил колеблющихся рабочих органов. Поставленная цель достигается тем, что в системе очистки зерноуборочного комбайна, содержащей раму,
