SU36713A1 - Automatic lifting mechanism for seed coulters - Google Patents

Description

The invention relates to automatic lifting mechanisms for seed coulters using a knuckle coupling, one part of which is a chain gear connected to the running wheel of the seed wheel, and the second is provided with an engaging roller.

In the proposed automatic lifting mechanism, the gear of one pole of the coupling is provided on the front side with two tides, and the second half of the clutch in the form of discs is provided with a through hole for the passage of the rollers under the action of a lever.

In FIG. 1 shows the general view of the mechanism from above; FIG. 2-gear; FIG. 3-part clutch with rollers; FIG. 4- part of the coupling adjacent to the lever with two windows.

Gear 1 (Fig. 1 and 2), freely mounted on shaft 2 (Fig. 1) and receiving movement from the traveling wheel of the spar using the Gall circuit, is included in the automatic lifting mechanism for the coulters. On the same shaft 2 is a clutch , one half 3 (figs. 1 and 3) of which is wedged on shaft 2, and the other half 4 (figs. 1 and 4) can rotate freely. Inside the clutch 3, two through windows 5 are made, in which (yes),. V

The rollers 6 (Figs. 1 and 3) can move under pressure of the pressure lever 7, rotating at point 8 (Fig. 1). For the free passage of the curved ends of the lever 7 to the rollers 6 in the disk 4, two windows 9 were made (Fig. 4). When not in use, the rollers are held in the position shown in FIG. 1 using a spring 10 fixed in part 3 of the coupling. When the lever 7 is pressed, its curved ends through the windows 9 of the disk 4. Push the rollers 6 through the windows 5 until they touch the tides 11 (Fig. 1 and 2) of the gear 1. This gear wheel rotates, as already indicated, from the crawler wheel , with its tides 11, carries away the disk 3, abutting against the rollers, as a result rotates the shaft 2 and raises the coulters of the seeds. The rollers carried by gear 1 make half turns and come to the other windows 5 of the same disk 3 and, if by that time the lever 7 is released, then the rollers under the influence of the spring 10 and roll back to their place again according to the provided slope, release the clutch with gear . Coulters remain raised. If necessary, they are lowered again by the lever 7 on the rollers and the described operation is repeated.

The subject matter of the invention.

An automatic lifting mechanism for coulter coulters using a clutch, one part of which is a chain gear connected to the running wheel

and the second is provided with an engaging roller, characterized in that the gear 1 is single ;, the coupling half is provided on the front side with two tides I, and the second half of the coupling in the form of discs 3, 4 has a through hole 9, 9 for passage of the rollers 6 by the action of the lever 7. .
