Combined precision seeder based on principle of built-in feeding

Abstract

The invention discloses a combined precision seeder based on the principle of built-in feeding. The combined precision seeder structurally comprises a main assembly body, storage boxes, a fixed frame,four drive motors, looseners, a sowing mechanism and driving wheels; rear ends of the drive motors are uniformly and equally distributed at the front end of the fixed frame. In order to prevent blockage, four material separation pipes respectively guide seeds in a material separation port into a material distribution mechanism, a feeding shaft in the material distribution mechanism is used for quantitative packing and is pushed down through a protruding push pin, a built-in rotating rod is in the static state in rotation, seeds are pushed out through a top-rotating cone head and are sown laterally to avoid accumulation in the soil, shaking of a shake-out mechanism can greatly increase the falling speed of the seeds, the whole use can guaranteed the accurate quantitative sowing, the position of the seeds is decentralized, the absorption of nutrients is greatly improved, and the impact on growth is prevented.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a combined precision seeder based on a built-in dialing principle. Background technique [0002] Seeder is a planting machine that uses crop seeds as the object of sowing. It is used for a certain type or a certain type of crop. The seeder is a common agricultural equipment that plays a vital role in the planting of wheat, corn and other crops. Among them, the seeding mechanism is the core of the seeder, which is the concentrated expression of the working performance of a seeder. Whether the seeding is appropriate or not directly affects the growth and production of crops. There are such problems in the use of existing technologies on the market: [0003] The current planters cannot achieve precise control, especially in the planting process of small-particle seeds, the error amount reaches the range of plus or minus 3 seeds, and the seeds are all placed in a concentrated manner, resu...

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 combined precision seeder based on the built-in dialing principle, so as to solve the problem that the current seeder cannot achieve precise control, especially in the process of planting small-grained seeds. The error amount is within the range of plus or minus 3 grains, and the seeds are put in concentratedly, which leads to the inability to absorb enough nutrients in the soil during the concentrated germination process, thereby reducing the germination rate, and the survival rate and growth rate of the seedlings cannot be improved. the presented problem
