Automatic seedling raising hole plate seeding assembly line

The automatic seeding assembly line is a modern agricultural automation machine that uses automatic seeding technology to improve seeding precision and efficiency. It is an advanced equipment for seedling companies to achieve large-scale production and promote industrialized seedling cultivation. Its main steps include mixing soil, feeding, substrate loading, hole pressing, seeding, soil covering, watering and dish out. The existing tray entry technology is that people place the hole trays on the mechanized seeding assembly line one by one, and after a series of procedures, the well seeded hole trays are stacked together. One assembly line needs to repeatedly stack 600-800 seeding trays per hour, which is labor-intensive in manual operation and increases the cost of seedling raising; This increases the labor intensity, reduces the production efficiency, and limits the improvement of mechanization efficiency.

In addition, when manually cooperating with the assembly line, it is necessary to keep pace with the assembly line. High-intensity work can easily lead to untimely delivery of the tray, resulting in blockage of the seedling hole tray on the assembly line, affecting the seeding effect and reducing the production efficiency; On the other hand, it is not easy to control the accuracy of manual stacking, and it is easy to skew or even topple, causing great losses.

The seeder is the key equipment of the factory seedling technology. The traditional mechanical seeder uses mechanical seed picking and releasing, which has a high rate of seed damage and is difficult to control the precision of plant spacing; The operation of magnetic suction precision seeder is cumbersome and inefficient; At present, the pneumatic precision seeder is widely used. The pneumatic precision seeder uses the air pressure difference to take out a single seed from the seed box and discharge it. It uses the air flow as the carrier to complete the seeding. However, the existing pneumatic seeder generally has the disadvantage that it is difficult to drop seeds with small particle size due to excessive adsorption, and it is easy to absorb impurities into the suction nozzle, which hinders the smooth seeding process.
