SU148290A1 - Vomer for square nesting forks - Google Patents

Description

Known coulters for square-nesting-si lok have significant frontal resistance, are structurally complex and do not provide high-quality seeding.

In the proposed coulter mounted directly under the sowing disc, the nest-forming device is made in the form of a rotating rotor with sectors.

This provides a reduction in drag coujHHKa and an increase in the time to calm seeds.

For sowing a given number of seeds into the nest in the opener, lining is applied, which are installed on top of the sowing disc so that the number of disk cells located above each sector of the rotor is equal to the number of seeds sown in one nest.

The turning of the sowing disc, rotor and opening of the valve can be performed from the measuring wire periodically using a knotter and a synchronizing clutch of a cellular or storage type.

According to the act of laboratory and field testing of SKGR-6 forks with 1 proposed coulter, an exact sowing of a given number of seeds into the nest is provided within the limits of agro demands.

The drawing shows the opener device.

The opener with a rotary valve nest-forming device is intended for square-nested sowing of tilled crops with a given number of grains in the nest.

The opener contains a sowing machine / with a horizontal arrangement of the sowing disc 2, having a peripheral cell arrangement, a rotor 3 with a vertical axis of rotation, a valve 4 driven by a knotter, a conical pair 5, which ensures synchronous rotation of the sowing disc with the rotor.

Sectors of the rotor 5 are directly placed under the sowing disc, which ensures dividing sm.n into portions, since the number of cells of the sowing disc located above the rotor sector determines

No. 148290 - 2 seeds in portions. The adjustment of the number of seeds in a chunk (12-3-4, etc.) is done with overlays mounted on top of the disk, the purpose of which is to cut off the extra cells of the sowing disk 2. When the coulter works, the rotor 3 and the valve are coordinated with each other using a synchronizing clutch cellular or storal type. The advantage of this joint is that the seeds are delivered by the rotor 3 to the valve 4 grouped in portions.

When the knotter fork is rejected, the following operations are performed.

Synchronization is activated, and α-coupling, thereby setting the sowing disk 2 and the rotor 5 into rotation; seeds from the cells of the sowing disk through the sowing window 6 - enter the sector of the rotor; the valve opens and the portions of the seeds on it enter the groove.

After the synchronization clutch is turned off, a period of lagging begins. This period continues until the next activation of the synchronization clutch.

The process described is repeated at each connection.
