Description
Technical Field
The utility model belongs to the technical field of agricultural seeder seed metering ware, concretely relates to does not hinder the bunch planting formula seed metering body of seed. Is suitable for sowing soybeans, mung beans, kidney beans and corns.
Background
Spring sowing requirement: uniform planting, no double-plant or seedling shortage, mechanical drill seeding, different soil fertility, different varieties and different acre yield. The prior mechanical seeding and seed discharging bodies have three types:
1. the air suction type seed discharging body has the defects that the more the number of seeding lines is, the higher the horsepower consumption is, the fan is easy to break down due to long-time high-speed rotation, the maintenance cost is high, and the seeding speed change has certain influence on the control of the air volume, so that the seeding speed is not uniform.
2. The finger-rest type seed sowing body needs to use a plurality of sets of seed sowing bodies when a plurality of seedling belts are sowed, so that the cost of the seeder is greatly increased. And the structure is more complicated, the failure rate is high, and the maintenance is difficult.
3. The advantages of the hole-seeding body are that the seed-seeding body has low cost and simple structure and convenient maintenance, but the seed-cracking phenomenon is caused if the seed-lubricating agent is not added in the traditional hole-seeding body, and the seed-cracking phenomenon can not be completely avoided even if the seed-lubricating agent is added.
In summary, the existing seed metering modes have problems, and the problem of seeding cannot be well solved.
Disclosure of Invention
An object of the utility model is to solve the problem that exists among the prior art, provide a many equidistant seed metering of grain, need not artifical spatfall final singling between the seedling, need not add the seed lubricant, do not crack the seed (press from both sides kind), no percentage of damage, the seed metering is rapid, and stability is good, and the commonality is strong, low price, easy maintenance's seed metering device.
In order to achieve the above purpose, the utility model adopts the following technique: a hole sowing type precision seed sowing body,
the seed retaining plates are formed by casting front and rear mounting flanges on the same shell; the rolling brush is contacted with the seed sowing wheel in the middle of the seed sowing body; a seed cleaning knife is arranged below the seed sowing wheel.
The seeding device comprises a further upper cover, a seed filling opening, a seeding tray arranged inside the shell, a rolling brush baffle sheet and a molecular device below the rolling brush baffle sheet. The seed sowing wheel is of a cylindrical structure, and the upper part of the seed sowing wheel is provided with a pit which is in accordance with the size of the seeds. In order to ensure the seed-sowing accuracy and avoid cracking, the sowing is designed at the intersection of the rolling brush and the seed sowing wheel.
The seed injection port is of a square structure and falls into the seed discharging body, the bottom end of the seed injection port is an incomplete inclined plane, and the distance from the deepest part to the top end is 54 mm.
Furthermore, the diameter of the seed wheel is 112mm, the width of the seed wheel is 39mm, each seed body is 3, and the seed wheel is replaced according to the size of seeds.
The diameter of the rolling brush is 71mm, and the width of the rolling brush is 38mm, and each seed discharging body is 3.
The rotation direction of the seed sowing wheel is the same as that of the hairbrush, namely the linear velocity direction of the seed sowing wheel at the intersection of the seed sowing wheel and the hairbrush is opposite, so that redundant seeds are brushed, and one seed in one hole is guaranteed.
The rotating speed ratio of the seed wheel to the rolling brush is 14: 27.
The distance between the rolling brush and the shaft of the seed sowing wheel is 90 mm.
Further, a seed cleaning knife is arranged below the seed sowing wheel, and seeds in the holes stably drop into the molecular device.
Furthermore, a molecular device is arranged below the seed sowing body, and the dropped seeds are respectively divided into two seedling belts or three seedling belts.
The beneficial effects of the utility model reside in that: seeds with different sizes can be sown by replacing different seed sowing wheels. The soft combination part between the rolling brush and the seed sowing wheel is used for sowing, so that the seeds are not clamped, the seeds are not damaged, the breakage rate is avoided, and no seed lubricant is needed to be added. The seed clearing knife can clear away the redundant seeds in time to improve the seeding stability. The seed discharging body has strong universality and can be exchanged and installed with the current popular seed discharging body.

Detailed Description
As shown in the figure, a hole sowing type precision seed sowing body is formed by casting seed separation blades and mounting flanges on the front and the rear of the seed separation blades on the same shell; the rolling brush is contacted with the seed sowing wheel in the middle of the seed sowing body; a seed cleaning knife is arranged below the seed sowing wheel.
Further, the seed injection port 4, the rolling brush baffle 5, the front mounting flange 15 and the rear mounting flange 13 are all cast into a cast iron shell body at one time. The transparent acrylic upper cover 1 is fixed on the shell by screws. As shown in the figure, the driving sprocket 9 drives the rolling brush wheel sprocket 11, and the sowing sprocket 10 rotates clockwise in figure 2. The rolling brush 6, the shaft and the bearing are arranged in the seed sowing body, and the rolling brush mounting cover 12 is arranged. The seed wheel 3, the shaft and the bearing are arranged in the seed body, and the seed wheel mounting cover 14 is arranged.
