Description

The utility model relates to agricultural engineering, in particular to seeders for precise sowing of large-fruited seeds, such as oak acorns, chestnuts, and garlic.

A known seeder [SU 982558, A1 USSR, MPK A01S 7/00, 12/23/1982] which consists of a hopper with a seed capture zone, a sowing device made in the form of an inclined elastic band with cells and a belt drive.

As a disadvantage of the seeder, we can note the low degree of filling the cells with seeds and the weak degree of retention of seeds in the cells due to the difference in the shape and size of the seeds.

The known wide-line nursery seeder SPP-3Sh [Posharnikov F.V. Forest seeders. 2007. 440 p.]. The seeder consists of a frame, a hopper, a coulter, a bobbin-mesh sowing apparatus, an inclined box-shaped seed tube, support wheels, a drive and closing working parts. In the SPP-3Sh seeder, the inclined seed tube, in order to increase the uniformity of seed dispersion, is equipped with a distribution device in the form of a cone with trap holes according to the patent [SU 1665910, A01C 7/20, 07/30/1991].

The disadvantage of the seeder is the low degree of filling of the reel cells with seeds and the difficult exit of large-fruited seeds from them.

A forest seeder is known for SLPM nurseries [Zima I.M. Mechanization of forestry work. 1976. 416 p.], including a hopper with tedders, conveyors with scoops for capturing seeds, seed receptacles, a coulter group and compacting rollers.

The disadvantage of the seeder is that the gripping devices in the form of scoops do not provide individual capture of seeds; large seeds fall out of the scoop, and small ones fall in the amount of more than one seed, which leads to an overrun of the seeding rate.

The closest analogues include a forest seeder for large-fruited seeds [RU 2603926 C1, A01C 7/00 (2006.01), 12/10/2016]. The seeder consists of a frame, a hopper, a sowing unit, a seed tube, a coulter, and a closing working element.

Among the disadvantages of the seeder is the lack of a mechanism for adjusting the precise sowing of seeds of various sizes. The seeding unit of the seeder has cells of non-adjustable size. Using a seeder to sow large-fruited seeds of different sizes, for example, acorns and garlic, can lead to overuse of seed. During operation, several small seeds can simultaneously fall into one cell of the sowing apparatus.

The utility model solves the problem of individual distribution of large-fruited seeds in the cells of the sowing apparatus.

The technical result is achieved through the use of bases of different sizes in the cells of the sowing apparatus. The bases are selected based on the size of the seed.

The essence of the utility model is that to implement this task, the proposed seeder for large-fruited seeds consists of a frame, a hopper, a support wheel, a sowing device, cells, a smaller base, a larger base, a seed tube, and a coulter.

At the same time, the seeder for large-fruited seeds is designed for precise sowing of large-fruited seeds. The seeder is a mounted implement mounted on a tractor. The design consists of a frame with a seed hopper. A support wheel is attached to the frame to adjust the depth of planting large-fruited seeds. The sowing device is made of cells. Each cell has a smaller and a larger base. A seed tube and a coulter are mounted under the sowing unit.

The seeder for large-fruited seeds will be clear from the following description and the accompanying drawings.

In fig. Figure 1 shows a diagram of a seeder for large-fruited seeds. In fig. Figure 2 shows view A of the cell of the sowing apparatus.

The seeder for large-fruited seeds consists of frame 1 (Fig. 1). A hopper 2 and a support wheel 3 are mounted on frame 1.

The sowing device 4 (Fig. 1, 2) consists of cells 5 (Fig. 2). In each cell 5, two bases of different sizes are simultaneously mounted - a smaller base 6 and a larger base 7. The smaller base 6 is designed to be removed from cell 5. The seeder for large-fruited seeds includes a seed tube 8 (Fig. 1) and a coulter 9.

The seeder for large-fruited seeds works as follows. Before sowing, the operator adjusts the cells 5 (Fig. 2). To set up, the operator evaluates the size of the seeds and compares them with the size of the smaller base 6 and the larger base 7. The choice of base is carried out based on ensuring the individual distribution of seeds in each cell 5. Seeding device 4 (Fig. 1, 2) without the smaller base 6 (Fig. 2 ) accommodates larger seeds. To be able to limit the size of cell 5 for small seeds, the operator leaves a smaller base 6 in cells 5.

During operation of the seeder, seeds from the hopper 2 (Fig. 1) fill the upper cells 5 (Fig. 2) of the sowing apparatus 4 (Fig. 1, 2). With further rotation of the sowing apparatus 4, the seeds fall into the channels of the seed tube 8 (Fig. 1) and continue to move down to the bottom of the furrow formed by the opener 9.

The proposed seeder for large-fruited seeds allows you to distribute seeds individually in the cells of the sowing apparatus and economically use seed material.
