Description

The invention relates to an agricultural machinery industry, in particular to low-sown seedless sowing machines, which can be used in sowing machines.

The purpose of the invention is to improve the uniformity of seeding of non-freeze seeds and reduce their injury.

In Fig.1 schematically shows the proposed sowing machine, side view; figure 2 is a section a - a in figure 1; on fig.Z - view B in figure 2.

The metering apparatus comprises a hopper 1, which is made in a longitudinal section that expands in the middle part and narrows at the top and bottom. In the middle of the expanded part of the bunker installed arching device, made in the form of two eccentrically mounted on the shaft of the disk 2, placed at the end walls of the bunker. On the side planes facing one another, the disks 2 are attached along their mutually opposite radii of the projections 3 of the triangular profile. The tops of the protrusions are directed toward the exit of the seeds, and the lateral faces are inclined to the plane of rotation of the disks at an angle a less than the angle of internal friction of the non-loose seeds.

The protrusions 3 are made with a variable section along the length, decreasing from the periphery of the disk 2 to its center.

In the lower part of the hopper 1 between the disks 2, a dispenser 4 is installed, located above the seed window 5. To ensure a more uniform direction of / 1-A

non-flowing seed current to sem wire under the seed, window 5, adjustable valve 6, installed coil 7.

The drive of the arching discs 2 with the projections 3, the dispenser 4 and the coil 7 is carried out through the gear-chain transmission 8.

Sowing machine operates as follows.

Seed material poured into the cavity formed by the side walls of the hopper 1 and the rotating disks 2, due to the presence of triangular protrusions 3 on the inner side planes of the disks, makes forced reciprocating oscillatory movements left and right, which ensures a constant compulsory loosening of the whole mass of non-loose seeds into the bunker apparatus. At the same time, the loosening of the seeds under the action of the rotating dispenser 4 is pushed through the seeding hole 5 to the coil 7, which directs the seeds evenly through this wire to the groove formed by the collar.

The required sowing rate is adjusted by changing the cross section of the sowing window 5 using the valve 6.

The complete elimination of arching allows us to withstand the stability and quality of seedless seeds sown by agrotechnics until the apparatus bunker is completely emptied, which leads to an increase in labor productivity at sowing due to the reduction of downtime for reasons of process disturbances.

Claims (3)

1. The sowing device containing a hopper with a sowing window and an adjustable shutter, a dispenser mounted on the shaft of the demolition drive with a drive, characterized in that, in order to increase the uniformity of sowing of loose seeds and reduce their injury, the demolition is made in the form of eccentrically mounted on the shaft with the opposite the eccentricity of the discs, on the lateral planes facing one another, on which protrusions are made along mutually opposite radii, with a transverse section of a triangular profile of variable length, whereby the cross-sectional area of the protrusions decreases from the periphery to the center of the disk. 2. The apparatus by π. 1, characterized in that the hopper in longitudinal section is made tapering in the upper and lower parts, and the disks are located at the flat end walls of the hopper, while the horizontal axis of rotation of the shaft is located in the plane of the largest cross section of the hopper. § 3. The device on the square. 1 and 2, characterized in that the side faces of the protrusions are inclined to the plane of rotation of the disks at an angle less than the angle of friction of the seeds.
