A combined seeder for rapeseed ridge cropping and direct seeding

Abstract

The invention discloses a rape ridge culture direct-seeding combined seeding machine. The rape ridge culture direct-seeding combined seeding machine comprises a transmission device, an earth entry amplitude fixing device, a rotary tillage device, a furrowing block forming device, a block surface management device, an earth scraping clearing device, a seeding device and a fertilizing device; the transmission device is used for transferring power, the earth entry amplitude fixing device comprises furrowing amplitude fixing small front ploughs at two sides of the right front side of installation; the rotary tillage device and the furrowing block forming device are used for furrowing, ridging and forming a block; the block surface management device is arranged behind a stander and between two furrowing amplitude fixing small front ploughs; the fertilizing device is arranged above the stander and in front of the seeding device; the seeding device is arranged above the rear of the stander, and a seeding opening of the seeding device is arranged behind the block surface management device. By adopting the rape ridge culture direct-seeding combined seeding machine, six tasks of operation such as soil rotary tillage, weeding stubble cleaning, furrowing ridging, formation of blocks, fertilization application and seeding can be completed simultaneously, so that the labor intensity is alleviated, the operation efficiency can be improved, and the high-quality high-efficiency integrated operation can be effectively realized.

Description

technical field [0001] The invention relates to a seeding machine, in particular to a rapeseed ridge-cropping and live-seeding combined seeder that forms a ridge into a box and integrates operations. Background technique [0002] Rapeseed is China's main oil crop. China's edible vegetable oil self-sufficiency rate is only 39.4%. The importance of rapeseed production has been raised to the height of national strategic security. The traditional way of planting rapeseed is inefficient and labor-intensive. Most of those who stay in rural areas to engage in agricultural production are old, weak, sick and disabled. Relying on this labor force structure and using traditional production methods cannot meet the requirements of large-scale expansion of rapeseed area and increase of total rapeseed production. Therefore, developing a series of rapeseed production machinery, assembling and integrating high-efficiency rapeseed cultivation technology, and realizing mechanized production ...

AI Technical Summary

Problems solved by technology

[0003] The winter rape production area in the south has sufficient rain before winter, which leads to overgrown weeds in the field, which seriously affects the growth of rapeseed seedlings, and the high stubble left in the field after harvesting the previous crops also seriously affects the emergence of rapeseed. Ditching and drainage, ridge formation, sowing and fertilization can be completed at one time, and the rape seeding machine is particularly important
