Soil preparation seeding all-in-one
The utility model belongs to the field of agricultural machinery, a be used for dark root class crops harvester of underground is related to, in particular to soil preparation seeding all-in-one.
With the continuous development of the mechanized land cultivation and preparation, among them, the rotary cultivator has been greatly popularized in recent years, and at present, when various technologies gradually mature, how to improve the production efficiency and save the machine tool consumption is one of the key problems of the land cultivation and preparation machine.
At present, a horizontal rotary cultivator occupies a dominant position in a soil cultivation and preparation operation link, but has a plurality of inevitable defects, wherein the most important is that under long-term rotary cultivation operation, a rotary blade extrudes soil, so that a plough bottom layer which is difficult to break through is formed, the plough bottom layer can reduce the growth space of crop roots and reduce the water storage and soil moisture conservation capacity of the soil. Adopt vertical rotary tillage operation, will avoid the appearance of plough layer greatly, compare traditional horizontal rotary tillage moreover, vertical rotary tillage still has advantages such as hack ability reinforce, the depth of cultivation is dark, realization no-tillage.
Under the current situation of agricultural mechanization, the situation of combined operation of multiple agricultural machines can be avoided during operation, most of the agricultural machines carry out independent operation, so that when one agricultural requirement is finished, another agricultural machine needs to be replaced for next operation, and time and labor loss is avoided; secondly, every round of agricultural machinery operation, the tractor all needs to carry out the compaction to farmland soil, reciprocates to cause soil compaction easily many times, reduces soil permeability and hydroscopicity. Therefore, the combined integration operation of multiple agricultural machines is necessary, the operation efficiency can be effectively increased, and the influence of the machine on the environment is reduced.
For the fertilization operation, there are generally three modes of broadcast sowing, furrow sowing and hole sowing, the fertilizer consumption of the broadcast sowing operation is large, the fertilizer can only be scattered on the soil surface, and the absorption of the fertilizer in the crop seed development process is hindered. The fertilization and seeding integrated operation in the traditional operation mode also has the defect of uneven fertilizer seeding.
