Description

Intermittent seed drill

Technical Field

The utility model relates to the technical field of seed drills, in particular to an intermittent seed drill.

Background technique

A seeder is a planting machine that sows crop seeds. It is a seeder used for a certain type or crop, and is often named after the crop type, such as grain drills, corn hole seeders, cotton seeders, forage spreaders, etc. In addition, sowing methods are also constantly improving. For example, the glue liquid sowing method using a peristaltic pump can eliminate the impact of adverse soil conditions on seed germination, and can also apply pesticides and fertilizers at the same time.

For example, the Chinese patent with the announcement number CN212211904U proposes a new forestry seed seeder. The patent starts the rotating wheel and the transmission device through the generator, pushes the push handle, drives the pulley group to move forward, and the rotating wheel edge moves forward while the rotating wheel rotates, and shovels holes in the land through the soil-scraping steel sheet. When the transmission device rotates, the sowing trough rotates through the transmission device. When the side plate of the sowing trough moves to the right, it squeezes the movable baffle toward the right side plate of the conveying pipe. At this time, the seeds enter the sowing trough from the seed storage trough through the conveying pipe, and the sowing trough rotates out through the transmission device. In the seed storage box for saplings, seeds fall into the holes dug by the soil-scraping steel blades, and the bulldozers push the soil around the holes into the holes to bury the seeds and prevent them from being exposed to the sun. However, in this solution, different saplings have different growth environment requirements, so when they are sown, the reserved spacing also needs to be changed. Since the holes are dug by the soil-scraping steel blades on the rotating wheels, and the spacing of the soil-scraping steel blades on the rotating wheels is fixed, the spacing of the holes dug by the soil-scraping steel blades on the rotating wheels is also fixed, which may not meet the sowing requirements and may affect the sowing effect of the saplings.
