Abstract

This article defines the parameters of the seeding disk designed for clustered sowing in a pneumatic seeding apparatus. To ensure the tight placement of seeds in the cluster, the holes in the group must be positioned as closely as possible. However, excess seeds tend to stick more to closely spaced holes than to individual holes.

To remove excess seeds, design a fork-shaped seed singulator, which is the most effective and commonly used design, has been applied. In this design, the two prongs of the seed singulator are positioned along a circular row of suction holes, “bordering” the seeds adhered to the holes and pushing away the excess ones. A constructive solution was determined for removing excess seeds from the suction holes arranged in two or three rows for clustered sowing.

This apparatus includes three seed singulators that can be adjusted in two different ways. The seed singulators are mounted on the cover of the seeding apparatus. A system of seed singulators consisting of two radial and one central seed singulator is used to remove excess seeds adhered to the holes of the seeding disk.

To maintain the required vacuum density in the vacuum chamber of the seeding apparatus, a fluoroplast gasket is installed between the body of the apparatus and the disc. It is recommended to use a radial type centrifugal fan as an exhaust device.
