Chain driven multi-shaft shallow-ploughing and furrowing device

Abstract

Provided is a chain driven multi-shaft shallow-ploughing and furrowing device for oilseed rapetransplantation. A three-point suspension is hitched to a rack and a bevel gear box respectively and used for being rapidly hitched to various power machine heads, power is transferred by a tractor PTO output device to the bevel gear box, the bevel gear box transfers the power to a side drive box, a multi-shaft shallow-ploughing assembly is connected with the side drive box, a furrowing assembly is coaxial with the first-shaft shallow-ploughing portion in the multi-shaft shallow-ploughing assembly, the side drive box transfers the power to the furrowing assembly and the multi-shaft shallow-ploughing assembly so as to drive the furrowing assembly and the multi-shaft shallow-ploughing assembly, a soil flatting plate assembly is installed on the rack and located above the multi-shaft shallow-ploughing assembly and used for flatting soil and finishing a compartment face. The multi-shaft shallow-ploughing assembly integrates a stubble cleaning portion, a shallow-ploughing device and a rotary tillage and furrowing device so as to achieve integration of rice field stubble cutting, rotary tillage, furrowing and soil throwing, shallow-ploughing soil breaking and soil flatting and compartment face finishing. In addition, multi-shaft shallow ploughing is adopted, so that shallow-ploughing soil aggregates are thin and broken, and mechanical transplantation and growth of oilseed rapeseedlings is promoted.

Description

technical field [0001] The invention relates to the technical field of agricultural transplanting machinery, in particular to a chain-driven multi-axis shallow plowing ditching device for rapeseed transplanting. Background technique [0002] my country's rapeseed production areas are mainly concentrated in the provinces of the Yangtze River Basin and the Yunnan-Guizhou Plateau. Hunan Province has fertile land, a mild climate, and a subtropical monsoon climate. It mainly grows rice, rapeseed and other crops. There are two ways of planting rapeseed and transplanting. Compared with Direct direct seeding and transplanting can not only increase the coincidence of crop growth time, shorten the field growth time, but also help increase yield or multiple cropping index; especially the use of soil-based pot seedling transplanting can shorten the greening period during the transplanting process and further shorten The field growth period is used to solve the contradiction of crop connec...

Problems solved by technology

[0003] However, the yield of rapeseed is low, and the planting income is low, especially in the planting of rapeseed seedlings, such as intensive cultivation such as plowing, rotary tillage, box lifting, seedling raising, and transplanting, which will greatly increase production costs, reduce income, and even lose money; if With no-tillage sowing, due to no-tillage sowing, the growth period of rape field increases, which is not conducive to multi-cropping planting, and the overall income is low; while using no-tillage transplanting, because the soil is more compact during rotary tillage and no-tillage transplanting, it is not easy It is good for the root growth of rapeseed, coupled with the low content of available nutrients in the soil, it is easy to cause premature aging of rapeseed and low yield
