Seedbed rotary cultivator for minimum-tillage precise combined direct seeder

Abstract

The invention discloses a seedbed rotary tilling device for less-tillage and fine-quantity rape combined direct seeder, which comprises right channel plates of the seedbed, left channel plates of the seedbed, ditching and fertilizing shovels, a right-rotary blade roller assembly, an anti-twisting blade and a left-rotary blade roller assembly, wherein each pair of the right channel plate and the left channel plate of the seedbed form a group of seedbed channel; the ditching and fertilizing shovels are arranged on the front side and the middle part of the seedbed channel; the left end of the blade shaft of the left-rotary blade roller assembly and the right end of the blade shaft of the right-rotary blade roller assembly are respectively arranged on a main frame, and the other ends are connected with each other through a spline housing; six groups of rotary blades are arranged on the blade shafts and are respectively positioned between each pair of the channel plates; and the anti-twisting blade is welded on the blade shafts of the left-rotary blade roller assembly and the right-rotary blade roller assembly and between a left-rotary blade holder and a right-rotary blade holder. The seedbed rotary tilling device can achieve operations of the fine-quantity rotary tillage, fertilizer groove ditching, deep fertilizing and filling of the fertilizer groove on the seedbed, and is suitable for the seedbed rotary tillage for no-tillage / less-tillage fine-quantity direct seeding operation for the seeds of the rape or other crops with front stubble crop covers.

Description

technical field [0001] The invention relates to the technical field of planting machinery in agricultural machinery, in particular to a seed bed rotary tillage device for rapeseed with less tillage and precision combined with a direct seeding machine. Background technique [0002] The traditional cultivation and planting of rapeseed is mainly carried out by raising seedlings and transplanting, which is labor-intensive, has many production processes and low production efficiency. At present, the existing seeders generally adopt the operation method of full-width and shallow rotation, the seed bed is not obvious, the depth of rotary tillage is not enough, and the depth of seed sowing is difficult to guarantee; the implementation of full-width rotary tillage has difficulties in effectively using straw, serious soil erosion, and the late stage of rape seedlings. The underdeveloped tap root system leads to defects such as poor lodging resistance of rapeseed. In order to meet the ...

[0002] The traditional cultivation and planting of rapeseed is mainly carried out by seedling cultivation and transplanting, which has high labor intensity, many production processes and low production efficiency

At present, the existing seeders generally adopt the operation method of full-width and shallow rotation, the seed bed is not obvious, the depth of rotary tillage is not enough, and the depth of seed sowing is difficult to guarantee; the implementation of full-width rotary tillage has difficulties in effectively using straw, serious soil erosion, and the late stage of rape seedlings. Underdeveloped main root system leads to defects such as poor lodging resistance of rapeseed; in order to meet the needs of conservation tillage, no-tillage / less-tillage combined direct seeding is the main technical development trend of rapeseed cultivation
