a peanut seeder

technical field

The utility model belongs to the field of agricultural equipment, in particular to a peanut seeder.

Background technique

Peanut is the main economic crop in my country. Due to the good planting efficiency, the planting area has increased year by year. Now the planting area has reached about 70 million mu. During the peanut planting process, the sowing and harvesting links are heavy, which is the most urgent mechanization problem to be solved. 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.

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.

Sliding in the ring groove, one side of the seed retaining plate is fixed on the inner wall of the housing through flange bolts, and the seed retaining plate and the surrounding wall rotate relatively; a seed outlet is provided under the housing side, and the seed exporting The opening is facing the lower end of the seed retaining plate, and the seed outlet is fixedly connected with the seed introduction pipe. With this design, a large number of peanut seeds enter the inner cavity of the shell and enter the surrounding wall of the sowing sieve. The seeding shaft drives the sowing sieve to rotate, thereby disturbing the seeds and reducing seed clogging. Reduce the damage of the red coat of seeds; the seed blocking plate cooperates with the ring groove to realize the flow control of peanut seeds.

Further, the depth directions of the two arc ends of the grain-passing through hole are inclined to the radial direction of the seeding sieve and away from the low end of the seed retaining plate, with an inclination angle of 10 to 30 degrees; the ends of the seed retaining plate are arc-shaped And has a rubber cover. With such a design, with the cooperation of the seed retaining plate, the excess seeds in the through-hole can be discharged into the seeding sieve along the inclined edge; the arc-shaped end face and the rubber sleeve can greatly reduce the damage of peanut seeds.

Further, an arc-shaped adjustment plate that can block two rows of grain-passing holes is provided under the inside of the surrounding wall, and one end of the adjustment plate is against the lower end of the seed blocking plate; one side of the adjustment plate passes through On the outer side wall of the housing, the adjustment plate moves relative to the side wall of the housing. With such a design, through the adjustment plate, the seeding sieve can be controlled to discharge two grains, single grain or no grain, so as to adapt to different situations.

Further, the seed introduction tube is provided with two channel cavities obliquely downward to the nozzle, and each channel cavity is respectively opposite to the particle passing hole that rotates through the seed outlet. Such design facilitates the smooth discharge of seeds from the seed guide tube.

Further, the shell is made of transparent plastic material. This design makes it easy to observe the internal conditions and troubleshoot problems in time.

Compared with the prior art, the beneficial effects obtained by the utility model are: the peanut seeds rely on their own weight, enter the main body of the sower from the sowing box through the sowing box, and a large number of seeds pour into the sowing cavity together, causing the seeds to be blocked. The shaft rotates the seeding sieve to disturb the seeds, thereby solving the problem of seed clogging. At the same time, the transparent shell can observe the internal situation at any time to prevent clogging; the peanut seeds are in the sowing sieve, and cooperate with the seed blocking plate to prevent the red coat of peanut seeds from being damaged; The adjustment of the adjustment plate can control the number of seeds; the seed guide tube makes the implantation position of the seeds more uniform. The utility model has the advantages of simple structure and convenient maintenance and use.
