Chain drive multi-shaft shallow tillage ditching method for oilseed rape transplanting

Abstract

A chain drive multi-shaft shallow tillage ditching method for oilseed rape transplanting can perform shallow tillage ditching by using a chain drive multi-shaft shallow tillage ditching device for oilseed rape transplanting. The chain drive multi-shaft shallow tillage ditching device for oilseed rape transplanting is hanged on a tractor through a three-point suspension device; a tractor PTO output device is connected to a bevel gear box of the chain drive multi-shaft shallow tillage ditching device for oilseed rape transplanting; the bevel gear box transmits power to a side transmission box; a multi-shaft shallow tillage assembly is connected o the side transmission box; a ditching assembly and a first shaft shallow tillage part of the multi-shaft shallow tillage assembly are coaxial; a soil flattening assembly for flattening soil and arranging bed surfaces is arranged on a rack; ditching blades for ditching and a shallow tillage blade tooth group for shallow tillage are arranged on a sharing rotary tillage shaft of the ditching assembly and the multi-shaft shallow tillage assembly. In this way, paddy field stubble cutting, rotary tillage, ditching, soil throwing, shallow tillage, soil smashing, soil flattening and bed surface arrangement can be performed integrally; and soil aggregates are fine through multi-shaft shallow tillage, thereby facilitating mechanical transplanting and growth of seedlings of oilseed rape.

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 method 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
