Double-row corn seeder pulled by mini-tiller by adopting auto-rotation and pit expanding principle

Abstract

The invention discloses a double-row corn seeder pulled by a mini-tiller by adopting an auto-rotation and pit expanding principle. The double-row corn seeder structurally comprises quantitative splitting bins, chain shafts, moving wheel sets, soil loosening shovels, traction arms, a fixed cross beam and storage boxes. According to the double-row corn seeder, conveying pipes are used for being connected with the quantitative splitting bins for receiving seed grains, at the moment, under driving of the moving wheel sets, the left ends of pressure levers are pried through stirring mechanisms, thepressure levers press the conveying pipes and seed splitting assemblies downward, finally, pressure rotating mechanisms make built-in reset pipes and pit expanding mechanisms rotate under pressure, the pit expanding mechanisms driven by rotation can effectively improve the soil breaking efficiency, soil shoveling stirring pieces automatically open discharge ports for material falling along the infiltration and support of the soil in the soil breaking process, so that the seeds can enter the discharge ports successfully, that is, the entering efficiency of the soil is improved, the damage of the seed splitting assemblies can be avoided, and the seeding depth is equally controlled.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a double-row corn seeder driven by a micro-tiller adopting the principle of self-rotating pit expansion. Background technique [0002] The traditional corn sowing is to use manual digging and blanking, but in the face of large-scale sowing work, it cannot be completed efficiently by manpower, and the artificial spacing of the sowing cannot achieve the effect of equidistant, so it is necessary to use a corn planter to Work to improve work efficiency and quality. The corn planter has the characteristics of uniform sowing, stable row spacing, good soil covering, seed saving, and high work efficiency. There are such problems in the use of existing technologies on the market: [0003] The current corn seeder adopts a conical direct-push pit, which cannot control the depth according to the quality and hardness of the soil. As a result, the depth of the pit will also change when encountering...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a double-row corn planter driven by a micro-tiller using the principle of self-rotation and pit expansion, so as to solve the problem that the current corn planter uses a conical direct push type to enter the pit. It is impossible to control the depth according to the quality and hardness of the soil, which leads to changes in the depth of the pit when encountering soil with a large difference in quality, and the long-term impact with the soil cannot guarantee the service life well, which needs to be optimized.
