Abstract
The utility model relates to the field of agricultural machinery, concretely relates to seed metering plate of a double-strip seeder on soybean ridge. The seed discharging plate comprises a long seed guiding groove, a short seed guiding groove, a hole nest, a shaft hole, a mounting hole and a seed discharging plate body. The long seed guide groove 1 is parallel to the central line of the short seed guide groove 2, and the included angle alpha between the long seed guide groove 1 and the horizontal groove is 28-29 degrees. When the seed-metering disc rotates in the seed-metering device, the seeds in the seed-filling area successively pass through the long seed-guiding grooves and the short seed-guiding grooves and accurately enter the hole nest, then the seeds rotate along with the long seed-guiding grooves and the short seed-guiding grooves, the seeds are forcibly pushed by the seed-metering disc and are discharged into the seed-guiding pipe through the seed-metering opening, and the seeds flowing out of the seed-guiding pipe fall into a seed ditch formed by the ditching disc, so that the seeding process is completed. The seed discharging plate has simple structure, good practicability and low manufacturing cost. The seed metering is accurate in the operation process, the consistency is good, the uniformity of the seed distance can be improved, the seedling emergence in the later period is neat, the seeding precision and the seeding quality are improved, and a solid foundation is laid for improving the grain yield.
Description
Technical Field
The utility model relates to the field of agricultural machinery, concretely relates to seed metering plate of a double-strip seeder on soybean ridge.
Background
With the continuous development of modern agricultural machinery and technology, field crop planting modes have been developed from traditional extensive sowing modes such as hole sowing, drill sowing and the like to precise sowing, mechanical sowing and the like. In the process of seeding operation, the seeding apparatus is a very important device, and the seeding plate is a key component of the seeding apparatus and plays a vital role in the seeding effect. The existing soybean seed metering disc is not suitable for double-strip precision seeding on ridges, and has the disadvantages of complex structure, high manufacturing cost and difficult maintenance. The seeding effect can not meet the requirement in the operation process, the phenomena of seed leakage and uneven seed sowing can not occur, the precision and precise seeding can not be ensured, the operation quality and the working efficiency of the seeder can be greatly reduced, the operation cost is increased, and great troubles are brought to users.
Disclosure of Invention
The utility model aims at providing a seed discharging plate of a double-strip seeder on soybean ridges. The seed discharging plate has good practicability and simple structure, and ensures the accuracy and consistency in the seeding process.
In order to achieve the above purpose, the technical scheme of the utility model is that: the seed discharging plate comprises a long seed guiding groove, a short seed guiding groove, a hole nest, a shaft hole, a mounting hole and a seed discharging plate body. The range of the length A of the long seed guide groove is 35-38 mm, the range of the length B of the short seed guide groove is 18-20 mm, the radius R of the shaped hole nest is 5-6 mm, and the edge of the nest hole is provided with a chamfer. The long seed guide groove is parallel to the central line of the short seed guide groove, and the included angle alpha between the long seed guide groove and the short seed guide groove is 28-29 degrees. The long seed guiding grooves, the short seed guiding grooves and the shaped pits are evenly distributed in an array along the circumference, the number of the long seed guiding grooves and the number of the short seed guiding grooves are respectively 30, and the number of the shaped pits is 60. The seed sowing plate body is provided with a shaft hole and a mounting hole.
When the seed-metering disc rotates in the seed-metering device, seeds in the seed-filling area successively pass through the long seed-guiding grooves and the short seed-guiding grooves and accurately enter the hole nest, then rotate, are forcibly pushed by the seed-metering disc, are discharged through the seed-metering opening, enter the seed-guiding pipe, and fall into a seed ditch formed by the ditching disc through the seeds flowing out of the seed-guiding pipe, so that the seeding process is completed. The seed discharging plate has simple structure, good practicability and low manufacturing cost. The seed metering is accurate in the operation process, the consistency is good, the uniformity of the seed distance can be improved, the seedling emergence in the later period is neat, the seeding precision and the seeding quality are improved, and a solid foundation is laid for improving the grain yield.

Detailed Description
As shown in fig. 1 and 2, the seed discharging plate comprises a long seed guiding groove 1, a short seed guiding groove 2, a hole nest 3, a shaft hole 4, a mounting hole 5, a seed discharging plate body 6 and the like. The range of the length A of the long seed guiding groove 1 is 35-38 mm, the range of the length B of the short seed guiding groove 2 is 18-20 mm, and the edge of a hole of the type hole pit 3 with the radius R of 5-6 mm is provided with a chamfer. The long seed guide groove 1 is parallel to the central line of the short seed guide groove 2, and the included angle alpha between the long seed guide groove 1 and the horizontal groove is 28-29 degrees. The long seed guiding grooves 1, the short seed guiding grooves 2 and the type hole pits 3 are evenly distributed in an array along the circumference, the number of the long seed guiding grooves 1 and the number of the short seed guiding grooves 2 are respectively 30, and the number of the type hole pits 3 is 60. The seed sowing plate body 6 is provided with a shaft hole 4 and a mounting hole 5.
When the seed-metering disc rotates in the seed-metering device, seeds in the seed-filling area successively pass through the long seed-guiding grooves 1 and the short seed-guiding grooves 2 and accurately enter the hole nest 3, and then rotate, the seeds are forcibly pushed by the seed-metering disc, discharged through the seed-metering opening, enter the seed-guiding pipe, and fall into a seed ditch formed by the ditching disc through the seeds flowing out of the seed-guiding pipe, so that the seeding process is completed.
