RU2537557C1 - Device for feeding of seeds into opening plow - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: device for seeds feeding contains the funnel divided into two symmetrically located sleeves, and flexible seed drop tubes, connecting the sleeves with opening plow. Above the sleeves the seed flow divider implemented as a twin trough plate, is installed. The bottom of each trough has reflecting protuberances. The divider is tilted towards the sleeves at the angle 12-20° with reference to the horizontal.

EFFECT: invention will allow to improve uniformity of seeds in a line.

Description

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

Known dividing the funnel of the opener (1), containing the receiving part, the guide channel, which is divided into two symmetrically arranged arms, where a reflective plate with a pendulum is installed to maintain the horizontal position of the plate.

A significant drawback of this dividing funnel is that when the seeder is working, a uniform distribution of the seed flow along the sleeves is achieved and a uniform distribution of the sowing material along the bottom of the furrow is not ensured.

Known nozzles for fertilizer wire (2), adopted for the prototype, made in the form of a cylinder, worn on the end of the fertilizer wire with a reflector of the seed in the form of a conical ring mounted with a gap from the bottom of the cylinder, through which the seed is distributed evenly in the form of a wide strip over the bottom of the furrow.

A disadvantage of the known nozzle is the inability to carry out row seeding, which is very important when sowing seeds of vegetable crops.

A patented device for feeding seeds to the opener is based on the same principle as the prototype, namely, on the reflection of the seed to be sown from the ledge of the plate, while the plate itself is tilted towards the sleeves and forms an angle within 12-20 ° with the horizontal.

The presence of protrusions on the inclined plate contributes to a uniform distribution of the seed on the bottom of the furrow.

The plate is pivotally attached to the funnel with the possibility of changing the angle of inclination of the plate with the horizontal and fixing it in a given position.

The plate is easily removable, which allows you to set the appropriate plate when changing the seed (for example, seeds of a different size). The plates have not only different lengths, but also protrusions-reflectors are made excellent in size and quantity, as well as their position at the bottom of the gutter.

The dimensions of the plate, as well as the size of the protrusions-reflectors, their number and their position on the plate are selected by calculation, so that the entire flow of incoming seeds is divided into two equal parts and they are evenly distributed along the bottom of the furrow formed by the opener.

The choice of the plate length determines the corresponding clearance between the plate and the end wall of the funnel, and the size of this gap eliminates any mash of seeds in this gap.

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 all essential features of the claimed device for feeding seeds to the opener. Thus, the patented invention meets the criterion of "novelty."

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

Figure 1 shows the described device for feeding seeds to the opener, General view.

A device for feeding seeds to the coulter contains a funnel 1, which is divided into two symmetrically located sleeves 2, flexible seed tubes 3, a plate 4 in the form of twin grooves 5, the bottom of each groove has protruding reflectors 6.

The plate at one end is pivotally attached 7 to the funnel 1, and the other end of the plate has been tucked under the locking pins, which makes it easy to set one or another angle of inclination of the plate itself.

Figure 2 shows the plate.

Figure 3 shows a diagram of the movement of seeds.

During the work of the seeder, the seed flow falling on the plate 4 is divided into two equal, the latter along inclined troughs, hitting and reflecting from the protrusions, flow down the sleeves in a leveled stream and then fall along the seed tubes to the bottom of the furrow formed by the opener, while the seeds are laid out exactly in a line with an equal interval between seeds.
