Nowadays, many vegetable and flower seedlings are planted by plug seeders, which benefit from the high efficiency of mechanical planting and high survival rate. Let's take a look at the design points of the planter.

According to the seeding method, the seeder can be divided into needle-suction seeder, flat seeder and drum seeder. According to the level of automation technology, they can be divided into manual, semi-automatic and fully automatic planters. my country's research and application started relatively late. After years of development, certain results have been achieved, but the contribution rate is still very low, the application is generally insufficient, and the development speed is relatively slow. There are still many people who choose to plant artificial services. With the development of modern agriculture and changes in characteristic agricultural methods, outdated seeding techniques and equipment cannot be integrated into new methods. There is an urgent need to develop mechanized precision seeding technology for plug seedlings. Our company has issued a fully automatic drum seedling tray seedling planter, which is faster, more efficient and intelligent.

When working, when the photoelectric sensor detects the plug, the conveyor belt stops moving, and the solenoid valve of the vacuum generator is opened to form air pressure inside the seed suction tube. The seed sucking cylinder promotes the sucking part of the sucking pipe. After 0.5 seconds of sucking time, the cylinder drives the sucking pipe holding the seeds back to the seeding position. At this time, the solenoid valve of the seed guide cylinder changes phases, and the cylinder moves down to promote the lower seed guide tube to fix the immovable plate, so that the lower seed guide tube extends into the pressed hole, the solenoid valve of the vacuum generator is turned off, and the seed tube is sucked. The external air pressure subsides; in addition, the blowing solenoid valve is opened to blow the adsorbed seeds out of the seed guide tube, and the solenoid valve is turned off after the blowing; in addition, the seed guide cylinder pulls the seed guide tube to the original position for a Sowing the holes in the row. The conveyor belt and the plugs are advanced by one hole interval, and the above actions are repeated, and the next seeding cycle system is continued. If the plugs are not checked, all the plugs will be seeded.

In this design, a stepper motor is used as an energy source. The speed ratio and stop position of the stepper motor are only the frequency and pulse number of the differential signal. During the seeding process, the distance between the stopper and the tray can be ensured according to the number of pulses from the control panel. In addition, the use of synchronization belts to transmit driving force can avoid the deviation of the conveyor belt and ensure a fixed transmission ratio. The use of stepping motors and timing belts to transmit driving force can further improve the positioning accuracy of the pallet. In addition, it can reasonably reduce the impact and vibration on the tray and the operating table.
