Description

Non-missing tillage chain drive throwing soil and stubble removal subsoiling rotary tiller

technical field

The invention relates to a rotary tiller, in particular to a subsoiling rotary tiller with chain drive for throwing soil and stubble.

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.

At present, the subsoiling rotary tiller adopts a set of heavy hook-shaped plow at the front end of the rotary tiller: the hook-shaped plow inserted into the soil is forcibly pulled by the strong traction force for subsoiling; the rotary tiller at the rear is then used for rotary tillage and crushing , There are also direct single subsoilers that do not perform rotary tillage and crushing. This type of subsoiler rotary tiller not only needs strong power traction, high power consumption, high manufacturing cost, and is easy to be damaged, but also has a single function and cannot achieve rotary tillage. Plowing, subsoiling, stubble removal and other multi-purpose effects of one machine.

The middle transmission tillage machinery, because of the corresponding lower end of the middle transmission box, cannot install the rotary cutter, which causes a 20cm wide blind area of rotary tillage and stubble removal, 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.
