Description

A kind of suction seed type seeder

technical field

The utility model relates to the technical field of agricultural machinery and equipment, in particular to a seed-suction planting machine.

Background technique

Sowing is an important part of the peanut production process. At present, film-covered planting is a major feature of peanut production in my country. Film-covered hole-piercing is a new sowing technology developed in recent years. It is beneficial to soil because it has little disturbance to the soil. Moisture conservation and drought resistance can also save the artificial membrane breaking link, while saving man-hours, avoid burning seedlings and ensure full seedlings. There are still many problems in the operation performance of the existing film seeders, and the domestic research is basically in the stage of individual technology research. The seeder is the core component of the seeder, and its working quality directly affects the performance of the seeder in the field. According to the principle of seed picking, it can be divided into two categories: mechanical type and pneumatic type. The pneumatic type seed picker has no strict requirements on the size of the seeds, does not need to be selected and graded, has less damage to the seeds, and is easy to achieve single-grain on-demand, and has the potential to increase the operating speed of the planter. have been extensively researched and applied. There are many problems in the existing domestic air-suction precision seeders. The operating speed is generally low. After the seeder increases the speed, the seeding quality will decrease significantly, resulting in a high cavitation rate. This is mainly due to the exhaustion of the air-suction seeder. The seed device is formed by the interaction of factors such as filling, clearing, scraping, and sorting under high-speed working conditions. Therefore, it is of great significance to solve the existing problems of the air-suction seeder and design a new structure.

Utility model content

Aiming at the defects of the prior art, the utility model provides a systemic seed seeder with simple structure, high seeding quality and no damage to seeds.

In order to solve the above technical problems, the utility model adopts the following technical scheme: a kind of internal suction seed sower, including traction frame, roller body, duckbill, inoculation box, air chamber and seed box, the air chamber is installed in the roller body, The seed box is connected to the air chamber; the roller body is connected to the traction frame; the duckbill is installed on the roller body, which is docked with the inoculation box, and the inoculation box is installed in the roller body. A transmission disc is installed on the transmission shaft, and a seed suction roller is fixed on the transmission disc. The seed suction roller is installed in the air chamber, and the air chamber is fixed on the transmission shaft through a bearing; the seed suction roller is provided with a seed suction hole for taking seeds; The air chamber is equipped with a trachea; a seed guide is also installed in the roller body, one end of the seed guide is docked with the seed suction roller, and the other end is docked with the duckbill.

Further, there is a slideway on the side wall of the air chamber, and the seed suction roller has a protruding sliding wall, and the seed suction roller is installed in the air chamber to form a sealed cavity through the sliding wall installed in the slideway. Rotate relative to the air chamber along the air chamber track.

Further, the air chamber is an annular groove structure with a cavity inside, one side of which is a disconnected part, and one end of the seed guide is opposite to the disconnected part of the air chamber. When the seed suction roller rotates out of the air chamber, the negative pressure disappears. The seeds on it fall into the seed guide due to their own weight.

Further, the transmission shaft is connected with the traction frame through a bearing seat.

During operation, the rotation of the roller body drives the transmission shaft to rotate, and the drive plate connected by the key drives the seed suction roller to rotate relative to the air chamber. On the seed suction hole; when turned out of the air chamber, due to the disappearance of the negative pressure, the seeds on the seed suction hole fall, fall into the corresponding inoculation box under the action of the seed guide, and enter the duckbill to sow into the hole.

The utility model drives the transmission shaft to rotate through the rotation of the roller body, and drives the seed suction cylinder to rotate relative to the air chamber. The seed suction hole absorbs the seeds under the action of the negative pressure of the air chamber. When it is turned out of the air chamber, the negative pressure disappears, and the seed suction hole The upper seed falls, falls into the corresponding inoculation box through the seed guide, and is sown into the hole through the duckbill. The quality of seed selection is effectively improved, and the damage to seeds is reduced.
