Automated sowing streamline for breeding plug tray

Abstract

The invention discloses an automatic seedling tray seeding assembly line. The seeding assembly line is sequentially fixed with a seedling tray upper tray device, a substrate laying device, a precision roller sowing device, a spraying device, a substrate covering device, and a seedling tray stacking device. A seedling raising tray is placed above the seedling raising tray upper plate device, and the seedling raising tray is pushed to the sowing line along the conveyor belt. The working efficiency of the assembly line of the present invention is 10 times that of the traditional artificial seedling raising mode, reduces the labor cost by two-thirds, and can significantly improve the quality of seedling raising. The operation is simpler, the work efficiency and quality are higher, the commonality of parts is better, the reliability and safety are higher, and the market prospect is very broad.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, and mainly relates to an automatic seedling tray seeding assembly line. Background technique [0002] The automatic seeding assembly line is a modern agricultural automation machine that uses automatic seeding technology to improve seeding accuracy and efficiency. It is an advanced equipment for seedling companies to achieve large-scale production and promote industrial seedlings. The main steps include mixing soil materials, feeding trays, substrates Packing, hole punching, sowing, soil covering, watering, and plate removal. The existing tray feeding technology is that people place the trays one by one on the mechanized seeding assembly line. After a series of processes, the sown trays are stacked together. An assembly line needs to repeatedly stack 600-800 seeding trays per hour. Plates, manual operation is labor-intensive and increases the cost of seedling cultivation; this inc...

Problems solved by technology

The existing tray feeding technology is that people place the trays one by one on the mechanized seeding assembly line. After a series of processes, the sown trays are stacked together. An assembly line needs to repeatedly stack 600-800 seeding trays per hour. The manual operation is labor-intensive and increases the cost of seedling cultivation; this increases the labor intensity, reduces production efficiency, and limits the improvement of mechanization efficiency

In addition, when working with the assembly line manually, it needs to be consistent with the pace of the assembly line. High-intensity work will easily cause the trays to be untimely, resulting in plugging of the seedling trays on the assembly line, affecting the seeding effect and reducing production efficiency. On the other hand, artificial The accuracy is not easy to control when stacking discs, and it is easy to be skewed or even dumped, causing great losses

[0003] The seeder is the key equipment of industrial seedling raising technology. The traditional mechanical seeder adopts mechanical seed picking and seeding, which has a high rate of seed damage and difficult to control the precision of plant spacing; the magnetic suction precision seeder is cumbersome to operate and has low operating efficiency; currently Pneumatic precision seeders are mostly used. Pneumatic precision seeders use airflow pressure difference to take out a single seed from the seed box and discharge it. The airflow is used as the carrier to complete the sowing.

However, the existing pneumatic seeders generally have the disadvantage of difficulty in dropping seeds due to excessive adsorption force for small-sized seeds, and are easy to absorb impurities to block the suction nozzle, hindering the smooth progress of the sowing process.
