Description

(5) COUNTER SEEDER

1 The invention relates to technical means that allow the selection and counting of seeds of agricultural crops, and can be used in seed control laboratories and breeding centers of the country as a 1k distribution counter when breeding new varieties and hybrids.

Known pneumatic counter spreader containing an electric motor, an aspirator, an air duct, a reading device with a set of reading plates

Disadvantages of the device - inaccuracy of reference, noise at work, relatively large losses of electricity.

The closest in technical essence to the present invention is a seed distributor, containing a source of alternating voltage, a reading panel fixed on the handle holder and made with cells in the shape of seeds, which are reinforced

electrodes connected via connecting wires with a source of alternating voltage. When the source is switched on to the grid, the electrodes of the reading panel are supplied with voltage across the connecting wires and a non-uniform electric field is formed around them. When the scorer is brought to the seeds, an electrical force acts on the latter, under the action of which the seeds are polarized, attracted to the electrodes and filled the cells made in the plate. The seeds are kept on the electrodes until the voltage is removed from them, after which they fall into growth cells or a cuvette.

However, for the selection and counting of large seeds, a high voltage must be applied to the electrodes, which reduces the quality of the reference, leads to the corona of the potential electrode, and under the action of ionization, the insulation is intensively aging, the electrodes are emitted from it impair the hygienic conditions of use. The purpose of the invention is to increase the reliability of the device. The goal is achieved by the fact that in the seed meter counter containing a source of alternating voltage, a reference panel fixed on the handle-holder and made with cells in the form of seeds and connecting wires, the reference panel is made of alternately arranged conductive and dielectric plates The conductive plates are connected via connecting wires to the corresponding terminals of the alternating voltage source. This is explained by the fact that the electric force acts in the immediate vicinity of the electrodes and depends not only on the intensity of the electric field, but also on the effective contact surface. The known counter-stretcher SJ / is a half-cylinder surface with a height equal to the gap thickness. as proposed, it is almost a hemisphere diameter equal to the diameter of the seed. Therefore, for this counter-distributor, the electrical force acting on the seeds will be higher with the same voltage on the electrodes as the known one. This follows from the principle of superposition of potential fields. Due to this, it is possible to reduce the voltage applied to the electrodes. FIG. 1 shows the counter-splitter, section; in fig. 2 — a reference panel with a plate connection scheme, a slit; in fig. 3 reading panel, bottom view. The seed calculator counter contains an alternating voltage source (not shown), a holding handle 1, a reading panel 2 made of conductive 3 and dielectric plates, and connecting wires 5. The counting terminal # to the seed works as follows. When the alternating voltage source is switched on, the bi-conductive plates 3 are alternated with the alternating field of the reference panel 2 on the reference panel 2 and the voltage is applied. Due to the principle of superposition of potential fields, due to the large number of conductive plates 3 of alternating polarity, a non-uniform electric field of increased tension is formed. Seeds that fall into the zone of action are polarized and, under the action of electrical force, are drawn to the conductive plates 3 filled in the 2 cells made in the reference panel and preventing two or more seeds from being attracted to one cell at a time. The seeds are kept in the cells of the reading panel 2 until they are removed from the last voltage from the source. This ends one cycle of operation and begins the next. As a result of using the proposed device, it is possible to reduce the voltage applied to the electrodes, to expand the range of operation of the replaceable reading panel, to reduce the number of reading panels in the set. Thus, the use of this counter-seed meter will improve the reliability and clarity of reference, unify the reading panels, improve hygienic and comfortable conditions of operation. Claims for a seed seeds clerk containing a source of alternating voltage, a readout panel mounted on a handle-holder and made with cells in seed form, and connecting wires, characterized in that, in order to increase the reliability of the device, the readout panel made of alternately arranged conductive and dielectric plates; the conductive plates are connected via connecting wires to the corresponding terminals of the alternating voltage source.
