Combined wheat uniform-sowing machine with spirally guided uniform-sowing mechanism

Abstract

The present invention provides an agricultural machine capable of uniform sowing of wheat, belongs to the technical field of agricultural machinery equipment, and discloses a combined wheat uniform-sowing machine with a spirally guided uniform-sowing mechanism, which is mainly technically characterized by comprising a suspension mechanism, a rotary tillage mechanism, a fertilizing mechanism, a sowing mechanism, a uniform-sowing mechanism, a pressing mechanism and a soil loosening apparatus, wherein the sowing mechanism comprises a seed box, a seed metering device and a seed sowing pipe, and the uniform-sowing mechanism consists mainly of a mandrel, and left and right spiral guide ribs. A principal operating principle of the combined wheat uniform-sowing machine is that seeds fall out of the seed box into the left and right spiral guide ribs within the uniform-sowing mechanism and then are uniformly sown into a fertilizer-soil mixture through a guide outlet, so that the uniform-sowing work of an entire working face is completed. According to the present invention, the fertilizer loss caused by the fact that the base fertilizer is placed on the surface or in shallow soil layer in thetraditional planting can be effectively avoided; the sowing depth of wheat can also be adjusted according to soil moisture content, thereby effectively improving the germination rate of wheat; as a result, damage to wheat seeds are avoided and the thickness of sowing is increased, allowing for a wheat yield increase.

Description

technical field [0001] The invention relates to a wheat compound level sowing machine adopting a spiral guiding level sowing mechanism, which belongs to the technical field of agricultural machinery and equipment. Background technique [0002] In order to increase the yield of wheat, increase soil air permeability, and facilitate the germination of wheat, it is generally necessary to use the method of uniform sowing to carry out rotary tillage on the soil, and complete the uniform sowing and fertilization while rotary tillage, on the one hand, reduce the cost of farming, on the other hand, improve Mechanization of wheat sowing. However, the traditional wheat leveling machine does not fully consider the rationality of the arrangement of the fertilization mechanism, the seeding mechanism, and the rotary tillage mechanism; and lacks the suppression and loosening of the soil, resulting in insufficient covering soil and covering soil density; when the soil moisture content is hig...

Problems solved by technology

However, the traditional wheat leveling machine does not fully consider the rationality of the layout of the fertilization mechanism, the seeding mechanism, and the rotary tillage mechanism; and lacks the suppression and loosening of the soil, resulting in insufficient covering soil and covering soil density; when the soil moisture content is high When the temperature is high, it is easy to harden; making the germination rate of wheat low

Moreover, the fertilizer cannot be evenly mixed with the covering soil; the sowing size accuracy of the seeds sown in the soil cannot be effectively guaranteed; the efficiency and quality of even sowing are affected, and the yield of wheat is reduced
