Peanut seeder

Abstract

The invention belongs to the field of agricultural equipment, and specifically relates to a peanut seeder. The peanut seeder comprises a seeding sieve, the seeding sieve comprises a round plate, a circumference-shaped wall is arranged on the outer diameter edge of one side of the round plate close to a seed feeding box, two rows of obround particle through holes are uniformly arranged along the circumference direction of the wall; two annular slots are formed in the inner side of the wall along a circumference direction, the two annular slots respectively penetrate through central lines of thetwo rows of particle through holes; and an arc seed blocking plate for shielding the particle through holes is arranged below the inner side of the wall. A large number of peanut seeds enter an innercavity of a shell so as to enter the wall of the seeding sieve, the seeding sieve is rotated through the driving of a seeding shaft, thereby disturbing the seeds and reducing the seed blocking; the seeding sieve is composed of the wall, the round plate and the particle through holes, and the red skin damage of the seed is reduced in the rotation of the seeding sieve; the seed blocking plate is matched with the annular slots to realize the flux control of the peanut seed.

Description

technical field [0001] The invention belongs to the field of agricultural equipment, in particular to a peanut seeder. Background technique [0002] Peanut is the main economic crop in my country. Due to its good planting benefits, the planting area has increased year by year. Now the planting area has reached about 70 million mu. In the process of peanut planting, the amount of work in sowing and harvesting is the most urgent mechanization problem to be solved. my country's peanut sowing has basically achieved mechanized sowing, but there are problems such as poor sowing effect and low efficiency. The main reason is that there are many technical problems in the seeder, the core component of the seeder. [0003] The seeder is the core and key component of the seeder, which directly determines the quality of sowing. The existing peanut seeders are mainly the outer groove wheel seeder and the spoon wheel seeder. At a certain speed, the peanut seeds rely on their own weight. E...

Problems solved by technology

my country's peanut sowing has basically realized mechanized sowing, but there are problems such as poor sowing effect and low efficiency. The main reason is that there are many technical problems in the seeder, the core component of the planter.

[0003] The seeder is the core key part of the seeder, which directly determines the seeding quality. The existing peanut seeders are mainly outer groove wheel seeders and spoon wheel seeders. Entering the main body of the seeder through the seeding box, due to the large amount of entry, a large number of seeds pour into the seeding cavity together, causing seed congestion, and it is easy for the seeds to be blocked and cannot be discharged. At the same time, the internal structure of the existing seeder is easy to damage the peanuts. Seeds cause a high rate of breakage, which cannot meet farmers' requirements for peanut sowing
