Description

technical field

The invention relates to the technical field of seed bed preparation, in particular to a seed bed preparation device and preparation method of a combined direct seeding machine of rapeseed.

Background technique

Tilling machinery is a key link in agricultural production, and its plowing quality directly affects the growth quality of crops. The cultivation and planting of rapeseed is mainly carried out by means of raising seedlings and transplanting, which is labor-intensive, has many production processes and low production efficiency. Existing seeders generally adopt the full-width and shallow-rotation operation mode, the seed bed is not obvious, the depth of rotary tillage is not enough, and the depth of seed sowing is difficult to ensure; the implementation of full-width rotary tillage has difficulties in effectively utilizing straw, serious soil erosion, and the main root system of rape seedlings in the later stage. Underdevelopment 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.

Just as the Chinese utility model discloses a seed bed rotary tillage device for combined direct seeding of rapeseed (public number: CN201207799), including the right channel plate of the seed bed, the left channel plate of the seed bed, the ditching and fertilizing shovel, the combination of the right rotary tiller and the Combination of winding blades and left-rotary tiller rollers. Each pair of seed bed right channel plate and seed bed left channel plate form a group of seed bed channels; ditching and fertilizing shovels are installed in front and in the middle of the seed bed channel; The right ends of the combined cutter shafts are respectively installed on the main frame, and the other ends are connected by spline sleeves; 6 sets of rotary tillers are installed on the cutter shafts, which are respectively located between each pair of channel plates; the anti-winding blades are welded to the combination of the left and right rotary tiller rollers On the knife shaft, it is located between the left and right rotary knife seats.

The current seed bed preparation device has the following disadvantages: 1. The traditional rotary tiller disrupts the soil fertility gradient from bottom to top, changes the original good soil structure, and reduces the ability of crop stubble to fix soil, resulting in soil compaction and drought resistance. 2. Due to the poor soil crushing effect, the soil is easy to cause sticky and heavy compaction, resulting in a low soil fragmentation rate, which is not suitable for seed growth.
