Abstract

FIELD: agriculture.

SUBSTANCE: device for feeding seeds into a coulter of a vegetable seed drill contains a funnel dividing into two or more branches, flexible seed ducts. The ends of the seed ducts are attached to a scatterer. The latter is made in the form of a quarter of the Bernoulli lemniscate. The scatterer bottom is made corrugated. The height of the projections of the corrugated bottom is made diminishing from the maximum at the entrance and to zero at the descent of the seeds from the scatterer. The corrugated scatterer bottom is made slidable for narrowing or widening the flow of seeds being sown.

EFFECT: invention will allow to increase the uniformity of seed distribution.

Description

The invention relates to the field of agricultural engineering and can be used for sowing seeds of vegetable crops.

1. Known dividing funnel opener [A.S. USSR No. 406500, АСС 7/20, publ. 04/27/72], containing the receiving part, the guide channel, divided into two symmetrically located sleeves, where a reflective plate with a pendulum is installed to maintain the horizontal position of the plate.

A significant drawback of this long funnel is that when the seeder is working, a uniform distribution of the seed flow over the arms is achieved, when their even number does not provide an even distribution of the seed flow with an odd number of arms.

1. Known nozzles for fertilizer conduit [A.S. USSR No. 350414, АСС 7/20, publ. 05/28/71], adopted for the prototype, made in the form of a cylinder, worn on the end of the fertilizer line with a reflector of the seed in the form of a conical ring installed with a gap from the bottom of the cylinder, through which the seed is uniformly distributed in the form of a wide strip along the bottom of the furrow.

A disadvantage of the known nozzle is the impossibility of narrowing or expanding the flow of sown seeds, which is very important when sowing seeds of vegetable crops.

A patented device for feeding seeds to the coulter is based on the same principle as the prototype, namely, on the reflection of the sowing material from the protrusion of the corrugated bottom of the diffuser, having the configuration of the fourth part of Bernoulli lemniscate.

The presence of protrusions, the height of which from the maximum at the seed inlet to the diffuser decreases to zero by the moment the seeds come off the diffuser, forms a uniform distribution of seeds in the flow along the width of the diffuser with the damping of seed vibrations in this flow as the flow approaches the exit from the bottom of the diffuser, regardless In addition, the flow channel narrows or expands.

This effect is achieved due to the fact that the bottom of the diffuser is made according to the lemniscate, when the reflected seed never strikes a second time on the same protrusion, since they move in different directions.

The dimensions of the bottom of the diffuser, as well as the size of the protrusions-reflectors, their number and their position on the lemniscate plate, are selected by calculation, so that the entire flow of incoming seeds is dispersed evenly in the falling amplitude-damped seeds coming down from the diffuser.

An analysis of the prior art by the applicant, including a search by patents and scientific and technical sources of information and identification of sources containing information about analogues of the claimed device for feeding seeds to the opener, revealed that the applicant did not find analogues for the device for feeding seeds to the opener, characterized by , similar to all the essential features of the claimed device for feeding seeds to the opener.

Thus, the patented invention meets the criterion of "novelty." To verify the compliance of the patented invention, a device for feeding seeds to the opener, with the criterion of "inventive step", the applicant conducted an additional search for known solutions to patents and scientific and technical sources of information. The search results showed that the patented invention, a device for feeding seeds to the coulter for the combination of distinctive features does not fall under the well-known technical solutions and does not follow explicitly from the prior art for specialists.

In FIG. 1 shows a funnel dividing the flow of seeds into two arms.

In FIG. 2 shows the bottom of the diffuser.

In FIG. 3 shows a diagram of the movement of seeds during operation of the seeder.

The device for feeding seeds to the coulter contains a funnel 1, which is divided into at least two sleeves 2, flexible seed tubes 3, a diffuser, made according to a curve forming 4-5 Bernunlli lemninskates, the bottom being made in the form of a corrugation, the height of the corrugations decreases from maximum at the input of the seed input to zero when the seeds come off the bottom of the scatterer, the decaying wave decays.

By the time the seeds come off the diffuser 6, the seeds stop jumping on the bottom of the diffuser and roll onto the surface of the soil strip formed by the coulter 7.

The corrugated bottom of the diffuser, consisting of two halves, is movable, they can be narrowed or the flow of seeds sown can be expanded with a constant width of the soil strip formed by the coulter.

A patented device for feeding seeds to the opener provides uniform distribution of seeds on the surface of the sowing strip.

During the work of the seeder, the flow of metered seeds entering the funnel is divided into at least two, the latter, falling on the corrugated bottom of the diffuser, hitting and bouncing off the protrusions, flowing down to the surface of the soil strip formed by the coulter with an even flow and are coarsened with soil.
