Cutter head deep-loosening stubble-ploughing rotary tillage multifunctional machine

Abstract

The invention relates to a cutter head deep-loosening stubble-ploughing rotary tillage multifunctional machine which comprises a transmission case assembly arranged on the side edge and a gearbox assembly arranged at the central position. The transmission case assembly comprises a coulter transmission case assembly and a deep-loosening knife transmission case assembly, and the coulter transmission case assembly and the deep-loosening knife transmission case assembly are connected to two sides or the same side of the gearbox assembly through support arm casings. The coulter transmission case assembly and the deep-loosening knife transmission case assembly both comprise a transmission case body, a driving chain wheel, a driven chain wheel, a transmission chain and a driven half shaft and are further provided with a coulter shaft assembly and a deep-loosening cutter head shaft assembly. Two ends of the deep-loosening cutter head shaft assembly and two ends of the coulter shaft assembly are provided with flanges, one end of the deep-loosening cutter head shaft assembly and one end of the coulter shaft assembly are connected with the driven half shaft through the flanges, and the other end of the deep-loosening cutter head shaft assembly and the other end of the coulter shaft assembly are connected with a bearing half shaft through the flanges. The cutter head deep-loosening stubble-ploughing rotary tillage multifunctional machine is reasonable in structural design and convenient to use and maintain, a series of field operation such as deep loosening, rotary tillage, seeding, fertilizing, stubble ploughing and ditching can be achieved simultaneously, and the problems of land hardening and the like which are caused by the fact that the land cannot be ploughed deeply due to interplanting structural model are effectively solved.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a cutter head subsoiling stubble removal multifunctional rotary tillage machine. 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] Moreover, the supporting farming machinery of the traditional old-fashioned chain transmission box is easy to cause severe mechanical failures such as broken chains, broken shafts, damaged bearings, sprockets, and even broken chain boxe...

AI Technical Summary

Problems solved by technology

Although the strength has been improved in this way, at the corresponding position of the intermediate transmission gear, there is a blind area of ​​about 20cm wide for rotary tillage and stubble removal due to the inability to install the coulter. This defect has not been solved by the prior art.

Even if a small fixed plow is installed, although the soil can be turned up, it cannot be crushed, thus forming a natural ditch, and at the same time, it also brings up the stubble that has been buried in the soil, which directly affects the quality of rotary tillage and sowing. and food production

[0004] What's more serious is that due to the rigid combined transmission between the tractor and the rotary tillage machinery, it is very easy to cause damage to the transmission shaft, transmission gear and bearings due to the instantaneous strong impact force, and it is more likely to cause damage to the transmission box assembly, etc. A catastrophic failure occurs

What's more troublesome is that once a fault occurs, a machine must be completely disassembled, and it takes more than three people and two to three working days to complete the repair, which not only results in high repair costs and time-consuming, but also delays farming. Seriously affected the economic income of farmers, so even the improved gear transmission not only failed to change the previous conditions of easy damage and unstable work, but also brought more disadvantages such as difficult maintenance, high maintenance costs, and delays in farming.
