Electric pneumatic seeder and seeding method

Abstract

The invention discloses an electric pneumatic seeder and a seeding method. The electric pneumatic seeder includes a main control chassis and a seeding apparatus. The main control chassis is internally provided with a power supply module, a vacuum pump, an air blowing pump and a solenoid valve; one side of the main control chassis is provided with scavenging ports; and the other side of the main control chassis is provided with a suction action switch and a suction opening, wherein the suction action switch is connected to the solenoid valve, and the suction opening is connected to the vacuum pump and the air blowing pump. The seeding apparatus includes a suction pipe, a replaceable suction needle arranged at the top end of the suction pipe, and a suction switch arranged at the front section of the suction pipe. The other end of the suction pipe is connected to the suction opening formed in the main control chassis, and the suction switch is connected to the suction action switch arranged on the main control chassis. During usage, the vacuum pump generates negative pressure to suck seeds, and the air blowing pump breaks the vacuum state to release seeds, so that semi-automatic accuracy control seeding of small seeds is achieved. The seeder is smart and is convenient to move. Compared with a conventional seeder, the seeder is high in seeding efficiency and precision and is suitable for seeding various fine seeds.

Description

technical field [0001] The invention relates to a seeder and a seeding method, in particular to an electric air suction seeder and a seeding method Background technique [0002] With the development of modern agriculture, sowing methods have gradually become more advanced, and automatic sowing has been realized. The size of the seeds varies with the species and varieties, and the sowing equipment and sowing methods used are also different. Generally, the place where automatic seeding can be used, usually has a large flat area and large seed particles, which is convenient for seeding and sowing by the seeder. As for the sowing method in the case of a small flat area and small seed particles, the traditional manual sowing is still used at present, and the efficiency is low. Simultaneously, although various large-scale seeding machines have high seeding efficiency at present, they are relatively inconvenient to move. They are not suitable for use in places with few flat areas...

Problems solved by technology

As for the sowing method in the case of a small flat area and small seed particles, the traditional manual sowing is still used at present, and the efficiency is low.

At the same time, although various large-scale seeding machines have high seeding efficiency, they are relatively inconvenient to move. They are not suitable for use in places with small flat areas and variable terrain, and are not suitable for sowing small seeds.

[0003] At present, the seeds of many vegetables and fruits are relatively small and have different shapes, such as: tomato: flat, kidney-shaped, silver-gray, with hairs on the surface, thousand-grain weight 3.0-3.3 grams; eggplant: flat kidney-shaped, yellow, new Seeds are shiny, 1,000-grain weight 4-5 grams, seed life 4-5 years, service life 2-3 years; pepper: flat kidney shape, slightly wrinkled surface, light yellow, spicy taste, 1,000-grain weight 5.0-6.0 grams Celery: double-hanging fruit, the seeds are actually fruits, oval, small, dark brown, with a strong fragrance, and the thousand-grain weight is about 0.47 grams; the particles of these seeds are very small, about 1 / 1 of the thousand-grain weight of rice seeds 18-34 grams 6~1 / 10; It is difficult to achieve fast and uniform sowing with conventional seeders

[0004] The accuracy and uniformity of the sowing depth have a great influence on the subsequent germination and growth of small plant seeds; if the sowing depth is too deep or too shallow, the seeds will germinate, grow too slowly, or even not germinate; if the same batch The uneven depth of seed sowing will easily lead to uneven germination and growth of plants, and the formation of large and small seedlings, which is not conducive to field management and high yield and harvest

Most of the current air-suction seeders are used to sow larger-grained seeds. The control of the seeding depth of this kind of seeder often requires the cooperation of other mechanical structures to achieve it. It is not convenient to use, and for The control of seeding depth and uniformity is not accurate enough
