Oilseed rape precision direct seeding machine based on crawler-type combined harvesting power platform

Abstract

The invention discloses an oilseed rape precision direct seeding machine based on a crawler-type combined harvesting power platform. The oilseed rape precision direct seeding machine comprises a harvesting system, a ploughing and seeding system and a suspension lifting device used for connecting the harvesting system and the ploughing and seeding system, wherein the suspension lifting device comprises a bottom frame, a suspension frame, a guide rail assembly, a lifting hydraulic cylinder and a pair of lifting chains; the pair of lifting chains respectively bypass guide wheels mounted on two sides of the hydraulic lifting cylinder, one end of each of the pair of lifting chains is fixed on the guide rail assembly, and the other ends of the pair of lifting chains are fixed on the suspension frame; and a rear support plate on the ploughing and seeding system is connected with the suspension frame through a central pull rod. Connection between a combined harvester and theploughing and seeding system and lifting of the ploughing and seeding system are achieved through the suspension lifting device, a chassis lifting hydraulic loop of the combined harvester is used for providing power forthe suspension lifting device, the suspension frame is driven to move vertically through the action of the lifting hydraulic cylinder, and therefore the lifting requirement of the ploughing and seeding system is met. The suspension lifting device solves the problem of connection between the combined harvester and the ploughing and seeding system.

Description

technical field [0001] The invention relates to the technical field of sowing in agricultural machinery, in particular to a rape precision direct seeding machine based on a crawler-type combined harvesting power platform. Background technique [0002] Rapeseed is the main overwintering crop in my country. Planting rapeseed can not only make full use of the fallow fields in winter and improve the land utilization rate, but also has a good role in land use and cultivation. Studies have shown that the widely promoted "rice-oil rotation" mode can increase rice yield per unit area Around 6.3%. The middle and lower reaches of the Yangtze River are the main rice-oil rotation cropping areas in my country. In view of the characteristics of heavy soil compaction, large moisture content fluctuations, and large straw retention in this area, the traditional rapeseed sowing operation mainly consists of tractor-mounted rapeseed machine completing stubble removal, Seed bed rotary tillage, fu...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a rapeseed precision direct seeding machine based on a crawler-type combined harvesting power platform, which uses the harvesting platform to collect and process residual stubble and floating grass in the field and throw them back, and completes the rape seeding operation before the straw is scattered, so as to solve the problem of rice oil tankers. The large amount of straw in the field affects the efficiency and quality of rapeseed sowing operations. At the same time, the utilization rate of the combine harvester is improved, and one machine with multiple functions is realized.
