Abstract

The utility model relates to the field of agricultural engineering and can be used in precision seeders for greenhouse and ground sowing.

The sowing apparatus for sowing radishes consists of a seed hopper, a rotating drum mounted on a shaft, and a casing. The drum of the sowing apparatus has holes-cells for the sown seeds. The drum has a three-row arrangement of cells. The distance between the rows of cells on the drum meets the agrotechnical requirements for planting radishes. Unloading of seeds from the cells occurs under the influence of gravity. The casing acts as a limiter for the seed scattering zone. The hopper contains plates with an angle of 35°. This allows you to reduce the loading area and increase the volume of seeds above the cell, increasing the likelihood of it being filled.

Description

The utility model relates to the field of agricultural engineering and can be used in precision seeders.

A known sowing apparatus contains a seed chamber installed in a housing, a rotating disk and a fixed disk, which is pressed against the plane of the rotating disk by a spring, characterized in that the cells are formed from grooves located along the periphery of the rotating disk from the side of the plane of the fixed disk (RF Patent No. 126557 IPC A01C 7/04, publ. 04/10/2013).

The objective of this technical solution is to improve the quality of sowing by eliminating the clogging of cells with seeds, increasing field germination and reducing injury to seeds - due to the design and shape of the cells of the vertical disk apparatus, which are formed by the plane of the fixed disk and grooves located along the periphery of the movable disk. This allows the seeds to freely fill the cells and fall out of them under their own weight, eliminating injury.

The disadvantage of this seeder is that the cells become clogged.

The closest technical solution to the proposed utility model is the seeder of the SMK-3 seeder, designed for three-row sowing of small-seeded vegetable crops in greenhouses, hotbeds and in open ground (Seeder of small-seeded crops SMK-3 (VPS27/1-10/4): [site /URL: https//tdrosta.ru/katalog/sredstva-mexanizacii/test-tovar-2-2-2html. Date accessed 05/04/2023). The SMK-3 seeder has a modular design that can be changed by adding sowing sections (up to 5 sections) to an extended shaft with stamped wheels. Three sowing sections of the SMK-3 seeder are fixed on a transverse shaft with an adjustable interval along the axes equal to the row spacing.

The disadvantages of this design include low seeding accuracy.

The purpose of this utility model is to simplify the design in order to increase the accuracy and uniformity of sowing small-seeded crops.

This task is achieved by creating a single body of a three-row sowing unit made of durable plastic using 3D printing technology. Due to this, the cost of the structure is reduced. In addition to the hopper, the sowing device contains a rotating drum with cells mounted on a shaft, which is partially covered with a casing. Restriction plates are installed in the hopper. The cell diameter allows for single filling, which increases the accuracy and quality of seed sowing. By installing a restrictive casing, the seed scattering area is reduced, while the sowing accuracy increases.

In fig. Figure 1 shows a diagram of the sowing apparatus (right view). In fig. 2 diagram of the sowing apparatus (front view). In fig. 3 diagram of the sowing apparatus (top view with arrangement of the hopper limit plates).

The sowing apparatus (Fig. 1) includes a seed hopper 1, a rotating drum 2 mounted on a shaft, a casing 3. The drum has holes - cells 5 (Fig. 2) for the seeds to be sown. The cell diameter is 4.5 mm, which is one and a half diameters of an average seed, which improves the quality of individual seed selection. The cells narrow downwards. Drum 2 has a three-row arrangement of cells 5. The distance between the rows of cells 5 on drum 2 is 80 mm, and between the cells in a row is 40 mm, which meets the agrotechnical requirements for planting radishes. Three-row seeding drum 2 allows you to increase the planting area in one pass. Unloading of seeds from cells 5 occurs under the influence of gravity. The casing 3, attached on one side to the hopper 1, acts as a limiter for the seed scattering zone. It partially covers the surface of drum 2 along an arc and along the length of drum 2. The gap between the restrictive casing and the seeding drum is 1.5 mm. In the hopper 1 (Fig. 2, 3) plates 4 are installed, the angle between which is 35°. This allows you to reduce the loading area and increase the volume of seeds above cell 5, increasing the likelihood of it being filled.

The seeder operates as follows:

The seeds enter the hopper 1, pass between the restrictive plates 4 and are distributed individually in the cells 5 of the drum 2, the restrictive casing 3 limits the seed scattering zone and ensures that the seeds enter directly into the unloading zone. Then the seeds fall into the ground under the influence of gravity.
