Background technique

Most mechanized operations in Northeast China are planted in uniform ridges, accounting for about 90% of the total operating area. Rotary tillage and stubble breaking are the two most common farming modes, which are completed by rotary tiller and stubble breaker respectively. In recent years, combined tillage and plowing machines that can complete the above two operations have appeared at home and abroad. There are mainly two types of combined operations machines in China: replacing different knife rollers to meet different operations; using double knife rollers, rotary tillage and crushing Stubble works at the same time. Though these two kinds of forms have greater progress than stand-alone, because of all having two knife rollers, two sets of blade fixing parts and two kinds of blades, still feel inconvenience in agricultural production. the
