Air suction roller type precision wheat direct-seeding and seed discharging device

Abstract

The invention belongs to the technical field of feeding equipment, and particularly relates to an air suction roller type precision wheat direct-seeding and seed discharging device. The air suction roller type precision wheat direct-seeding and seed discharging device comprises a seed box (1), seed sucking needles (2), seed sucking slotted holes (3), a sealed regulating device (4), a seed sucking roller (5), an air blowing chamber (6), a seed discharging shaft (7), a seed discharger body (8), an air sucking chamber (9) and sealing elements (10). The air suction roller type precision wheat direct-seeding and seed discharging device is characterized in that four groups of the seed sucking slotted holes (3) are uniformly distributed in the seed sucking roller (50), the air sucking chamber (9) and the air blowing chamber (6) are distributed on the seed discharger body (8), and the sealed regulating device consists of a locking spring, a spring seat and a locking nut. The air suction roller type precision wheat direct-seeding and seed discharging device disclosed by the invention is simple in structure, high in practicality, low in cost, high in adaptability and good in generality; the seed sucking single grain rate can be increased; the seed sucking needles (2) approach to seed crowds from bottom to top, so that the seed crowds are prevented from forming pits due to the situation that the seed sucking needles (2) impact seeds when approaching to the seed crowds from top to bottom, and the influence of the uneven surface of a seed layer on seed suction is avoided.

Description

technical field [0001] The invention belongs to the technical field of seeding equipment, and in particular relates to an air suction roller type wheat precision direct seeding device. Background technique [0002] Wheat belongs to the Triticum genus of the grass family, and it is one of the earliest cultivated crops in the world. After long-term development, it has become one of the food crops with the widest distribution, the largest area, the second total output, the largest trade volume and the highest nutritional value in the world. [0003] There are 43 countries in the world, and 35%-40% of the population takes wheat as the main food. Wheat grains are rich in starch, more protein, a small amount of fat, and a variety of mineral elements and vitamin B. It is a commercial grain with rich nutrition and high economic value. [0004] Since the output of wheat planting areas in my country has stagnated in the past ten years, the general yield per mu is about 500 kilograms...

AI Technical Summary

Problems solved by technology

Most of the traditional planting forms and seeding machines are drill planting models, and the output has reached the limit of about 500 kg. The planting forms and planting machines are backward, with defects and deficiencies, and it is difficult to increase the output.

Moreover, due to the low rate of agricultural mechanization in my country, agricultural machinery has not been used on a large scale. According to the traditional wheat planting method, the yield of wheat has not been greatly improved.
