Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. Device is proposed for treating the surface of seeds with protective-stimulating preparations, including a drum with a drive, on the raised side of which a seed hopper and a sprayer for feeding the working fluid are installed. Inside the drum, ring inserts are fixed, forming a solid cylindrical surface. Width and the value of the coefficient of friction of the inner surface are chosen taking into account the increase in the intensity of mixing of the seeds of different cultures, due to the difference in the angles of the rise of the seeds in individual sections of the drum.

EFFECT: invention makes it possible to improve the quality of seed treatment of different crops.

Description

The invention relates to agriculture and can be used for seed treatment with protective stimulating drugs.

Known dresser containing a drum, a mechanical transmission and a drive [1].

Also known is a device for seed treatment, containing a container for seeds in the form of a cylindrical drum mounted on a horizontal axis. Inside the drum, guide elements are fixed for moving the seed layer during processing in the form of blades and means are located for distributing the filler or processing substance [2].

Also known devices for presowing treatment, consisting of a drum made in the form of bodies of revolution, the inner surface of which is made in the form of helical grooves [3, 4].

The disadvantage of these devices is that the mutual mixing of seeds is carried out in the plane of rotation and is largely determined by the geometry and kinematics of the drum without taking into account the influence of the friction coefficients of the seeds on its inner surface, which have a significant dispersion by types of crops and their condition, in particular humidity, which the pre-sowing process varies significantly.

The invention allows to obtain a new technical effect - increasing the intensity of mixing of seeds of various crops due to the difference in the elevation angles in individual sections of the drum. This effect is achieved by the fact that annular inserts forming a continuous cylindrical surface are fixed inside the drum, and their width and the value of the coefficient of friction of the inner surface are selected taking into account the increase in the intensity of mixing of seeds of different crops due to the difference in the angles of rise of seeds in individual sections of the drum.

In FIG. 1 shows a general diagram of a device; FIG. 2 - a fragment of a drum with rings installed (view A of FIG. 1).

The device for pre-sowing treatment includes a tilted rotating drum 1, inside of which annular inserts 2 are fixed, forming a continuous cylindrical surface. In this case, the annular inserts 2 can have different widths S and are made of materials having different friction coefficients, the values of which are selected from the conditions for optimizing the operating modes of individual sections of the drum. On the raised side of the drum 1, a loading hopper 3 for seeds is installed, and a sprayer 4 with a discharge pipe 5 for supplying the working fluid.

A device for presowing processing works as follows. The seeds of the cultivated culture are fed from the raised side of the rotating drum 1 to a continuous inner cylindrical surface formed by annular inserts 2. At the same time, the working fluid in the form of small droplets (aerosol) formed by the sprayer 4 due to the pressure in the discharge pipe 5 is supplied to the seed drop zone.

Seeds lying on the inner surface of the rings 2, move around the circle in the direction of rotation of the drum 1, entraining the upper layers of seeds, while the speed of movement of the upper layers decreases with distance from the seeds lying on the inner surface of the rings 2. Having reached the maximum angle of elevation, the seeds, under the action of gravity, begin a radial movement downward and along the generatrix towards the tilt of the drum 1. At the same time, on the ring inserts 2 having a greater coefficient of friction, the seeds rise to a larger angle and, reaching corner fittings lifting when moving in the zone of transition to the annular insert 2 with a lower coefficient of friction does not occur with moving up the seeds, as on these annular inserts 2, the angle of maximum seed rise is lower. This contributes to the mutual mixing of seeds not only due to radial, but also axial movement, which significantly increases the intensity and uniformity of the application of the drug on their surface.

The width S and the value of the friction coefficients of the inner surface of the annular inserts 2 are selected depending on the technological parameters of the process (type of seeds, their moisture content, etc.) taking into account the increase in mixing intensity due to the difference in the height of the seeds in separate sections along the length of the drum 1.

Thus, the proposed technical solution provides a technical result: universalization of the seed dresser and improving the quality of seed treatment of agricultural crops.
