Description

The invention relates to agricultural machinery, in particular to the selection of sowing machines. The purpose of the invention is to improve the uniformity of distribution of seeds along the row. The sowing machine contains a guide tube 1 with a divider in the form of rods 2. · The rods 2 are set at an angle to the axis of the tube with their free ends forming a central axial hole. The ratio of the hole diameter to the distance between the free ends of the rods along the perimeter is 2: 1. The device also has a cone 4 in the cylinder 6 with outflow window 8 and equalizer 9. When working, the seeds go through the tube 1 and the divider into the cylinder 3. When the latter is lifted, the seeds are distributed by the cone 4 and when it rotates enter window 8 to the equalizer 9 and then sent into the seed tube. 2 Il.

The invention relates to agricultural machinery, in particular to the selection of sowing machines.

The aim of the invention is to improve the uniformity of distribution of seeds along the row.

Figure 1 shows a diagram of a conical metering device, a side view; figure 2 - divider, top view.

The proposed apparatus consists of a guide tube 1 with a divider in the form of rods 2, mounted under the ·, γ angle to the axis of the tube in the loading cylinder 3, resting on the cone 4 with the disk 5. The cone installed in the outer cylinder 6 forms the seed channel 7. In the outer cylinder made discharge port 8, for which is fixed equalizer 9,

When working seeds through a direction; The tubing 1 and the divider 2 enter the loading cylinder 3. When it is lifted by the cone 4, they are distributed along the seed channel.7. By rotating the cone 4 and the disk 5, the seeds are fed through the outflow port 8 to the equalizer 9 and then sent to the seed tube.

If, when fed into the apparatus, the seeds in the guide tube are not located in the center, then they, when passing into the divider, encounter resistance of the bars and the more seeds,

In the meantime, a significant number of them are delayed and sent to the center of the divider, where they freely pass into the loading cylinder. The result is a redistribution of seeds in the splitter. This ensures that the bulk of the seed is fed through the center of the guide tube in any direction of the seed flow when it enters the tube.

Claims (1)

Claim A conical metering device containing a guide tube, a loading cylinder, an outer cylinder enclosing a conical distributor, c. the lower part of which is equipped with a movable disk and a seed equalizer, characterized in that, in order to increase the uniform distribution of seeds along the row, in the upper part of the guide tube there is a divider, made in the form of rods rigidly fixed on its inner surface, which are angled to the axis of the tube with the formation of their free ends of the central axial hole, with the angle of inclination of the bars equal to the angle of inclination of the equalizer to the axis of the disk, and the ratio of the diameter of the hole to the distance between one ends of the bars on the perimeter is 2: 1.
