SU1222215A1 - Disc furrow opener - Google Patents

Description

The invention relates to agricultural machinery, in particular, coulters for the simultaneous sowing of seeds of different crops with different depth of embedment in the soil.

The purpose of the invention is to ensure the sowing of seeds of various crops.

FIG. 1 shows a disc coulter assembly, side view; in fig. 2 - interposition of body sections and disks.

The disk coulter comprises a housing 1, made sectional, a receiving funnel 2 with a socket 3, disks of a large 4 and smaller 5 diameters. The coulter body 1 consists of two sections — a fixed 6 and a movable 7, on which axes the disks 4 and 5 are mounted. On the fixed section 6 of the body there is a groove 8, and on the mobile 7 a ledge 9 with a “dovetail” section. Holes 10 are made at the bottom of the groove at equal distances from each other for two locking bolts 11. For the convenience of installing the opener to the embedment depth at holes 10, it is possible to set

Create a scale with numbers showing the difference between the embedment depths of simultaneously sown seeds. On the disk of smaller diameter 5, a hole 12 is made for locking bolts 11.

Disk opener works as follows.

Depending on the type of crops being sown at the same time, the difference between these depths is determined on the basis of the values of the depth of their embedding according to agrotechnical requirements. Before the start of operation of the unit, this difference is set on all the coulters, which are then adjusted together with the (set screw) locking bolts 11 and the furrows are cut and sown in them, thereby seeding the seeds of different crops to different depths. When sowing seeds of other crops, sections 6 and 7 of the coulter body are retooled, i.e., their height is adjusted relative to each other.
