The distributor of the seeder sowing device for different depth sowing is made in the form of a roller with three cells located at an angle of 45 ° from each other, the profile of the first cell has the shape of a curved surface connecting the middle and right parts of the roller along the radius, the profile of the second cell is a cone-shaped recess made by in the middle of the roller, and the profile of the third cell has the shape of a curved surface connecting the middle and left parts of the roller along the radius, characterized in that in the first and third cells the movement of seeds is limited by the side wall of the roller curvilinearly connected to the middle part of the roller cell. Technical result - improved quality the distribution of seeds of row crops, melons and vegetables of various sizes in the opener compartments for different seeding in the soil with simultaneous exclusion of their injury.

Description

The utility model relates to agricultural engineering, in particular to the design of the seeder section for sowing row crops, melons and vegetables.

A known seeder section for multi-level nesting seeding of row crops, containing a bracket, an articulated lever parallelogram suspension, a pneumatic sowing device with a hopper, a dispenser, a three-level opener, stubblers, a rolling wheel and a train. A distributing device in the form of a roller with three cells located at an angle of 45 ° from each other is installed under the pneumatic metering device, while the profile of the first cell has the shape of a curved surface connecting the middle and right parts of the roller along the radius, the profile of the second cell is a cone-shaped recess, made in the middle of the roller, and the profile of the third cell has the shape of a curved surface connecting the radius of the middle and left parts of the roller (RU 2626757 from 07/31/2017).

The disadvantage of the design of this sowing section is that the technical result is aimed at the formation of the nest due to the roller of the dispensing device, which has no restrictive side walls in the first and third cells.

There is a chance of injury to the seeds with a slight gap. In the absence of a gap, noise and additional energy consumption from friction forces increase. There is wear parts.

The objective of the claimed utility model is to eliminate this drawback.

The technical result is an increase in the quality of distribution of seeds of row crops, melons and vegetables of various sizes in the opener compartments for different depth seeding in the soil while eliminating their injury.

The indicated technical result is achieved by the distributor of the seeder sowing apparatus for different depths of nest sowing in the form of a roller with three cells located at an angle of 45 ° from each other, while the profile of the first cell has the shape of a curved surface connecting the middle and right parts of the roller along the radius, the profile of the second the cell is a cone-shaped recess made in the middle of the roller, and the profile of the third cell has the shape of a curved surface connecting the radius of the middle and left portion of the roller, wherein the first and third cells seed movement is restricted sidewall roller curvilinearly connected to the middle portion of the roller cell.

The design is illustrated by drawings.

In FIG. 1 shows a distribution roller (general view).

In FIG. 2 - distribution roller (top view).

In FIG. 3 - profile of the first cell (section AA in Fig. 1).

In FIG. 4 - profile of the second cell (section BB in Fig. 1).

In FIG. 5 is a profile of a third cell (section BB in FIG. 1).

The distribution device is made in the form of a roller 1 (see Fig. 1 and 2), mounted on the drive shaft. On the roller 1, grooves are made, forming three cells 2, 3, 4, located at an angle of 45 ° from each other. The profile of the first cell 2 (see Fig. 3) has the shape of a curved surface that connects the middle and right parts of the roller 1. The profile of the second cell 3 (see Fig. 4) is a cone-shaped recess made in the middle of the roller 1. The profile of the third cell 4 (see Fig. 5) has the shape of a curved surface connecting the radius of the middle and left parts of the roller 1. The synchronous rotation of the seed disk and the roller is ensured by a chain transmission.

The distribution of seeds by roller into the corresponding openings of the opener is as follows.

In the zone of atmospheric pressure, the seeds are separated from the disk and, under their own weight, fall down into the middle part of the roller 1 for sequential distribution in the cells. If the seed enters the first cell 2, then due to the shape of the profile it is shifted to the right side of the roller and gently stops at the side wall, with further rotation of which it is sent to the right compartment of the three-level opener. When the seed enters the second cell 3, no displacement occurs and the seeds are fed into the main compartment of the three-level opener. The direction of the seeds in the left compartment is due to the third cell 4, the profile of which moves the seeds to the left side of the roller 1 and is also limited by its side wall. Smooth braking of seeds in front of the side wall of the roller is due to the curvilinear connection with its side wall.

Thus, the profile of the cells and the presence of the side wall of the distribution roller will allow to exclude injury to the seeds of row crops, melons and vegetables, as well as to sow them in different ways regardless of their size and shape.

Claims (1)

The distributor of the sowing apparatus of the seeder for different depths of nest sowing, including a roller with three cells located at an angle of 45 ° from each other, while the profile of the first cell has the shape of a curved surface, connecting the radius of the middle and right parts of the roller, the profile of the second cell is conical a recess made in the middle of the roller, and the profile of the third cell has the shape of a curved surface connecting the radius of the middle and left parts of the roller, characterized in that in second and third cells seeds limited movement sidewall roller curvilinearly connected to the middle portion of the roller cell.
