A kind of farmland soil three-dimensional finishing machine

Abstract

The invention discloses a three-dimensional finishing method for farmland soil. The method performs three-dimensional finishing on the mellow soil layer of one finishing belt and the raw soil layer of the adjacent finishing belt, so as to obtain the mellow soil belt and raw soil which are alternately distributed horizontally. It can realize the purpose of thickening the mellow soil layer and accelerating the ripening of the raw soil. At the same time, it discloses a three-dimensional soil finishing machine for farmland, including a frame. The inner sides of the two side plates of the frame are sequentially fixed from right to left. The three-dimensional finishing mechanism, Raw soil three-dimensional finishing mechanism and soil distribution and paving mechanism, wherein, mellow soil three-dimensional finishing mechanism includes mellow soil tillage mechanism and mellow soil shovel mechanism; raw soil three-dimensional finishing mechanism includes raw soil tillage mechanism and raw soil shovel mechanism; The soil distribution paving mechanism includes a transfer mechanism. The technology and supporting equipment can simultaneously arrange the soil three-dimensionally in the horizontal and vertical directions, thicken the mellow soil layer and separate the raw soil layer in the short term, accelerate the maturation of the bottom raw soil in the long run, and realize the overall and long-term thickening of the soil in the ploughing layer. Fertilize.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a three-dimensional soil finishing machine for farmland. Background technique [0002] Affected by high-intensity agricultural utilization, the soil physical and chemical properties of cultivated land, especially sloping cultivated land, deteriorated, and the prominent manifestations are soil compaction and shallow cultivated layer, which make the soil water holding and fertilizer supply capacity insufficient, and the land productivity declines significantly, which has become a constraint to the sustainable development of agriculture. main factor. In order to thicken the ploughing layer, loosen the compacted soil, and maintain soil fertility, deep plowing (including deep loosening, deep plowing, and complete soil layer replacement) and ridge farming are currently being implemented, supplemented by certain fertilization measures, such as planting Green manure, straw returnin...

AI Technical Summary

Problems solved by technology

However, this tillage method is similar to subsoiling in nature, and it also has the problem of short duration of effect; although ridge tillage can realize the thickening of the plow layer without disturbing the structure of the plow layer, but this tillage method has no effect on promoting the deep soil layer. The raw soil maturation effect of ridge farming is limited, and it cannot "open source" the soil of the plow layer. At the same time, ridge farming has poor adaptability in seasons and areas with insufficient rainwater resources, which limits its practical application in constructing a reasonable plow layer.
