Problems solved by technology

[0002] At present, the rotary drum seeders on the market have the defects of low seeding accuracy, poor cavitation, and unstable seeding rate.
The sowing accuracy is poor. The reason is that when the cylinder rotates, the seeds are turned in the inner cavity of the shell. When they encounter the leaking hole on the shell wall, they will leak out without seeding, which leads to more and less seeds leaking out.

Embodiment approach 1

[0021] A seed metering device used on a rotary seeder, which is in the form of a hollow box (1), with a seeding inlet and outlet (2) and a seeding outlet (5) on the box wall, and a box inner cavity Seed storage bin (3), seed taking spoon (4); the mouth of the seed storage bin is opposite to the mouth of the seed taking spoon, the seed discharge inlet and outlet are located under the seed taking spoon, and the seeding outlet 5 is located behind the seed storage bin The volume of the seed storage bin is greater than the volume of the seed taking spoon; the seed discharge inlet and outlet, the sowing outlet, the seed storage bin and the seed picking spoon have respectively interconnected seed passages.

[0022] The seed meter is fixed on the peripheral wall of the housing (6) of the rotary drum seeder ( figure 1 , figure 2 , image 3 ), the seed discharge inlet and outlet (2) communicate with the inner cavity of the housing (6) through the peripheral wall of the housing.

Embodiment approach 2

[0024] This mode is basically the same as Embodiment 1, the difference is that the seed metering device is fixed on the inner peripheral wall of the inner cavity of the housing (6) of the drum type seeder ( figure 1 , Figure 7 ), the sowing outlet (3) leads to the outside through the peripheral wall of the housing.

Embodiment approach 3

[0026] This mode is basically the same as Embodiment 1, the difference is that the seed metering device's seed metering inlet and outlet are located on the side of the hollow box ( Figure 5 ), there is a seed return slope (9) on the opposite side of the seed discharge inlet and outlet. The seed meter is located on the outer side wall of the housing (6) of the rotary drum seeder ( Image 6 ), the seed discharge inlet and outlet communicate with the inner cavity of the housing through the side wall of the housing (6).

[0027] In this way, since the seed discharge inlet and outlet are not directly below the seed picking spoon, after the seed return slope is added, the redundant seeds can flow back into the inner cavity of the housing along the slope during seed discharge.

[0028] The seed metering device is simpler in structure than the rotary bin type seed metering device, but has the seeding effect of the rotary bin type seed metering device; the structure is simpler than t...

Abstract

The invention provides a seed sowing device used for a rotary barrel type seeder. The appearance of the seed sowing device is a hollow box body; a seed-sowing seed inlet / outlet and a seeding outlet are formed in the wall of the box body, wherein a seed storage cabin and a seed taking spoon are arranged in an inner cavity of the box body; the opening surface of the seed storage cabin is opposite to the opening surface of the seed taking spoon; the seed-sowing seed inlet / outlet is located under the seed taking spoon; the seeding outlet is located behind the seed storage cabin; the capacity of the seed storage cabin is larger than that of the seed taking spoon; and seed channels, which are communicated with one another, are formed among the seed-sowing seed inlet / outlet, the seeding outlet, the seed storage cabin and the seed taking spoon. Compared with a rotary cabin type seed sowing device and a spoon wheel type seed sowing device, the seed sowing device provided by the invention is simple in structure and has similar effects, and also has the advantages of no damages to seeds and no blocking. The seed sowing device can be matched with a power machine, so that high-speed seeding is realized. At present, farmers almost utilize the rotary barrel type seeder, and the seeding precision of the seed sowing device is higher than that of the rotary barrel type seeder; and the conversion and upgrading of the seed sowing device are very easy and the seed sowing device has good market prospect.

Description

technical field [0001] A seed meter used on a rotary seeder relates to the field of seeders. Background technique [0002] The rotary drum seeders on the market all have the defects of low seeding accuracy, poor cavitation, and unstable seeding rate. The sowing accuracy is poor. The reason is that when the cylinder rotates, the seeds are turned in the inner cavity of the shell. When they encounter the leaking hole on the shell wall, they will leak out without seeding, which leads to more and less seeds leaking out. . Contents of the invention [0003] Add a seed meter before the seeds are sown to improve the sowing accuracy. [0004] Technical solutions: [0005] A seed metering device used on a rotary seeder, which is characterized in that it is a hollow box body (1), with a seeding inlet and outlet (2) and a sowing outlet (5) on the wall of the box body. The inner cavity has a seed storage chamber (3) and a seed taking spoon (4); the mouth of the seed storage chamber...
