Background technique

According to the current long-term intercropping structure pattern of double-cropping or multi-cropping crops, the land cannot have enough time and opportunity for deep plowing, and the land is easy to harden, making it impossible for crop roots to penetrate deep into the soil to absorb deep water, ground temperature and nutrients. It causes serious consequences such as weak seedlings, sick seedlings, easy to freeze to death in winter, and even lodging and no harvest, which seriously affects grain production and national food security.

With the rapid advancement of my country's mechanization process, the popularization and application of large and super large agricultural machinery, the original matching rotary tiller, stubble remover, rotary seeder, ridger, ditcher, subsoiler and other tillage machines The variable speed transmission box is no longer suitable for the supporting use of the current high-horsepower agricultural machinery, and it is easy to cause severe mechanical failures such as broken chains, damaged bearings, gears, and even broken transmission box assemblies, especially for farming machinery with intermediate transmission. The corresponding lower end of the transmission box has a 20cm wide blind spot for rotary tillage and stubble removal due to the inability to install the rotary cutter, which has not been able to solve this problem so far. It directly affects the stubble removal and sowing quality of rotary tillage, thus affecting the grain yield.
