Uniform-sowing seeder

Abstract

The invention provides a uniform-sowing seeder. The seeder comprises a sowing depth control part and a uniform sowing head; the uniform sowing head comprises a seed guide part and a division part; oneend of the seed guide part is connected with a seed guide pipe of the seeder, and the other end of the seed guide part is communicated with an inlet of the division part; the division part is arranged on the sowing depth control part; the interior of the division part is divided into a plurality of discharging grooves through division walls; the sowing depth control part is arranged on a cross beam of the seeder, located behind a rotary tillage cutter set and used for adjusting the soil entering depth of the uniform sowing head. According to the seeder, the consistent sowing depth of the seeds and uniform sowing can be achieved at the same time, the seeds can be more uniformly distributed, the development and growth of crops are facilitated, the yield and income of the crops are increased, and the agricultural development is promoted.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a uniform sowing seeder. Background technique [0002] The uniform sowing technology is based on the growth and development characteristics of crops, and fully utilizes the coordination mechanism of uniform and robust individual crops and sufficient and reasonable groups. The uniform distribution of crops in uniform sowing operations creates a condition of balanced nutrition for a single plant, and the individual nutrition competition in the seedling stage is small. , the growth of a single plant is robust, which is beneficial to the formation and development of dominant tillers, promotes the growth and robustness of a single plant, and fully exerts the yield formation potential of dominant tillers, so as to achieve high yield and high efficiency of crops. At present, some uniform sowing machines have appeared in China, but most of them use the dense row sowing technology, w...

AI Technical Summary

Problems solved by technology

For crops sown in dense rows, the sowing depth is still inconsistent, so that the growth speed of the crops becomes different, and there will be uneven emergence, which is not conducive to the increase of crop production. In addition, for crops sown in dense rows, the difference between the front and rear plant spacing and the left and right plant spacing is still relatively large. Large, does not fully reflect the advantages of uniform sowing technology
