No-missing chain-driven rotary cultivator with functions of soil casting, stubble cleaning and subsoiling

Abstract

The invention relates to a no-missing chain-driven rotary cultivator with functions of soil casting, stubble cleaning and subsoiling, which comprises a chain drive box assembly disposed in an intermediate drive manner. A power input shaft and a transmission sprocket shaft are disposed inside the front end of a chain drive box, and a power input sprocket is further disposed on the transmission sprocket shaft. A power output shaft is disposed inside the rear end of the chain drive box, and a power output sprocket is disposed on the power output shaft. A transmission chain is disposed on the power input sprocket and the power output sprocket. Two ends of the power output shaft respectively extend out of the chain drive box to be connected to a coupling with a flange, the coupling is connected with a subsoiling cutter shaft assembly, and a turning tool and a coulter are disposed on the coupling. The subsoiling cutter shaft assembly is connected with a support shaft through the flange, the support shaft is connected to a support arm, and the support arm is connected with the chain drive box through a support casing. The no-missing chain-driven rotary cultivator with functions of soil casting, stubble cleaning and subsoiling is simple in manufacture, easy in production, low in cost, high in universality, convenient in maintenance and energy-saving, and has rotary cultivation, stubble cleaning and subsoiling efficiency approximately doubled.

Description

technical field [0001] The invention relates to a rotary tiller, in particular to a subsoiling rotary tiller for throwing soil and removing stubble with chain transmission without missing tillage. Background technique [0002] 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. [0003] 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...

Problems solved by technology

[0002] According to the long-term interplanting structure mode of the current double-cropping or multi-cropping crops, the land cannot have enough time and opportunity for deep plowing, and the land is easy to harden, so that the root system of the crops cannot penetrate deep into the soil to absorb deep water, ground temperature and nutrients.

It has caused serious consequences such as weak seedlings, diseased seedlings, easy to freeze to death in winter, and even lodging and no harvest, seriously affecting grain production and national food security issues

[0003] 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

[0004] For tillage machinery with intermediate transmission, the 20cm wide blind area of ​​rotary tillage and stubble removal is caused by the inability to install the rotary cutter at the corresponding lower end of the intermediate transmission box, which has not been able to solve this problem so far.

Directly affect rotary tillage stubble removal and sowing quality, thus affecting grain yield
