69 results about "Seed drill" patented technology

A seed drill is a device that sows the seeds for crops by positioning them in the soil and burying them to a specific depth. This ensures that seeds will be distributed evenly. The seed drill sows the seeds at the proper seeding rate and depth, ensuring that the seeds are covered by soil. This saves them from being eaten by birds and animals, or being dried up due to exposure to sun. With seed drill machines, seeds are distributed in rows, however the distance between seeds along the row cannot be adjusted by the user as in the case of vacuum precision planters. The distance between rows is typically set by the manufacturer. This allows plants to get sufficient sunlight, nutrients, and water from the soil. Before the introduction of the seed drill, most seeds were planted by hand broadcasting, an imprecise and wasteful process with a poor distribution of seeds and low productivity. Use of a seed drill can improve the ratio of crop yield (seeds harvested per seed planted) by as much as nine times.The use of seed drill saves time and labor...

A roller-type double-action finger-clamp precision seed drill

The present invention discloses a roller-type double-action finger-clamp precision seed drill, belonging to the technical field of seeding equipment. The seed-picking assembly includes a paddle, a second elastic element, and a finger clamp. The finger clamp includes two finger clamps, namely an active finger clamp and a passive finger clamp. The middle parts of the two finger clamps are hinged and the hinge point is fixed to the seeding disk. The second elastic element is used to push the heads of the two finger clamps to rotate in directions away from each other. During the rotation of the seeding disk, when the finger clamp rotates to enter the seeding opening, the passive finger clamp rotates under the action of the second elastic element to unload the seeds. When the finger clamp leaves the seeding opening, a cam drives the active finger clamp to rotate, causing the head of the passive finger clamp to extend into the shell. In the present invention, after the seeds are picked up by the finger clamp, they are clamped and protected by the two finger clamps, thereby separating from the inner wall of the shell. Therefore, when the finger clamp continues to rotate, the seeds no longer rub against the inner wall of the shell, which is beneficial to protecting the seeds and reducing the friction damage they suffer, which is beneficial to improving the survival rate of the seeds.
