Background
The rotary cultivator is a cultivator which is matched with a tractor to complete the operations of ploughing and harrowing. The soil breaking machine has the characteristics of strong soil breaking capacity, flat ground surface after ploughing and the like, and is widely applied. The rotary cultivator has the functions of breaking a plough bottom layer, restoring a soil plough layer structure, improving the soil water storage and preservation capacity of soil moisture, eliminating part of weeds, reducing plant diseases and insect pests, leveling the ground surface, improving the standard of agricultural mechanized operation and the like. The rotary tillage cutter shaft is divided into a horizontal shaft type and a vertical shaft type according to the configuration mode of the rotary tillage cutter shaft. The transverse shaft type rotary cultivator with the cutter shaft horizontally arranged is more applied. The classification has stronger soil-breaking capacity, can make soil finely broken by one-time operation, has uniform soil and fertilizer mixing and smooth ground, meets the requirements of dry land seeding or paddy field planting, is favorable for striving for farming season, improves the work efficiency, and can fully utilize the power of a tractor. But has poor covering capability on stubble and weeds, shallow plowing depth and large energy consumption.
