Abstract

The invention relates to agricultural machinery. The aim of the invention is to reduce the time to adjust the depth of the coulters. The crop contains a bunker with sowing devices communicated with the material guides of 9 single disc coulters 11, which are hinged on the leads 12. Centurions have support rollers 10, which are also hinged on the frame of the splices with the help of leads 13. On the sleeves 12. And 13 are installed pivotally interconnected bushings 14, which with the help of connecting rods 16 and cranks 18 are pivotally connected to the shaft 19, on which the control lever 20 is rigidly fixed. Turning the control lever 20 in one direction or another, is moved with the help cranks I8 and connecting rods 16 bushings 14 relative to the leads 12 and 13, thereby changing the angle between the leads 12 and 13 and, accordingly, the relative position of the height of the coulters 1I relate to the rollers 10. 10 Il. i (L

The invention relates to agricultural machinery, namely, forks that can be used for sowing various types of materials (grain and leguminous crops), fertilizing with fertilizers, soil application of tukov, sowing of grass crops, etc.

The purpose of the invention is to reduce the time to adjust the depth of the coulters.

Figure 1 shows the side view of the plant; figure 2 - soshnikov group, side view; figure 3 is the same, top view.

The crop contains frame 1, a hopper with containers 2 and 3 for sowing materials, sowing devices 4, bundles of wires 5, footplate 6, spring drivers 7, press rolls 8, material guides 9, support rollers 10, right and left ones - Nodiskovy coulters 11, leads of 12 coulters and installed at an angle to them leads 13 support rollers. On the leads of 12 coulters and 13 support rollers, sleeves 14 are freely mounted, which are connected by hinges 15 between themselves and to the frame by means of a crank mechanism, made in the form of a connecting rod 16, connected by a hinge 17 to a crank 18 fixed on the shaft 19 with a control lever 20 secured thereto, which has a spring-loaded retainer (not shown) entering the inter-gear space of the toothed sector fixed to the frame 21. The drivers 12 and 13 of the openers and support rollers are hinged on the shaft 19.

Selka works as follows.

Sowing materials from containers 2 and 3 mounted on frame 1 are seized by sowing devices 4 and fed into material directors 9 and grooves opened by disc coulters 11. Sown into soil

the seeds are sealed and rolled by the rollers 8 mounted on spring leads 7 at the rear

The change in the depth of the coulters 11 is made by changing the position of the press rollers 10 relative to the coulters. This is achieved by having the gate of the control lever 20 in one direction or the other by moving the cranks 18 and the connecting rods 16 of the sleeves 14 relative to the leads 12 and 13 of the openers 11 and the supporting rollers 10, thereby providing

15 thereby changing the angle between the leads 12 and 13 and, accordingly, the relative position along the height of the coulters 11 relative to the support rollers 10.

The use in the planting of a decentralized device for changing the seeding depth of various materials will ALLOW to reduce the time for reconfiguring the universal seed, simplified25

its design, reduce the cost (replacing several brands of locks with one) and expand the scope of its application.
