FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular: to the coulters used in seeding machines.

The opener is known, which makes a leash with a disk knife and a furrow with it installed on it with this funnel flj.

The disadvantages of the known coulter are the sticking of the coulter when working on wet soil and the uneven placement of seeds on the slopes due to deviation of the seed and, therefore, the coulters from the direction of movement of the sowing unit.

The closest technical solution to the invention is openers containing a leash connected to a U-shaped frame on which a circular knife is installed and: this direction of the funnel, the circular knife being spring-loaded relative to the U-shaped frame in the transverse direction 2.

The disadvantages of these coulters are sticking them in the soil during operation.

in wet areas, a significant amount of dirt is available for their movement and limited ability to rotate coulters in a horizontal plane, which affects the uniformity and quality of seed placement when working on slopes.

The purpose of the invention is to improve the process of self-cleaning of the coulter from the soil and reduce the drag resistance of

10 direction of travel.

This is achieved by the fact that the habits are provided with a guide with a vertical axis, and the U-shaped frame has a slider with a groove, the slider being podshuzhinen relative to the leash and installed in the guide so that the vertical axis is located in the slider groove.

Claims (2)

The opener contains a U-shaped frame 1, between the longitudinal bars of which the disk knife 3 is mounted on the axis 2, and the guide funnel 4 with the adjustable adjustable reflector 5 is fixed on the frame 1 on the frame 1. On the axis 6 the leash 7 is movably mounted with a vertical axis 8 attached a guide: 9, made in the form of a cylindrical sleeve. The axis 8 is fixed by a nut 10. At the ends of a straight 9, bearings 11 are installed to reduce sliding friction, which are closed by covers 12. Frame 1 has a crawl 13 in the front part, which enters the direction 9, 9 and has a longitudinal groove through which the axis passes 8. The slider 13 is connected to the driver 7, in which groove 14 is made, with the help of spring 15, the tension of which is adjusted by nut 16. To copy the soil relief, pressure rod 17 is attached to spring 7 with a spring 18. The opener works on the slope following in a way. The disk knife 3 forms a boil in the soil, at the bottom of which seeds fall from a seed funnel 4 with a reflector 5. When the crop deviates from the direction of movement due to sliding on a slope or a curved path of movement on a plain, the disk knife 3 with this guide hopper 4 under the action of lateral forces is set in the direction of movement, providing a predetermined seed-seeding uniformity. The frame 1 is rotated around the axis 8, and the spring 15 is elastically deformed. The rotation of the disk is limited by the size of the groove 14 in the leash 7 4. H). . Since the frontal part of the disk knife 3 and this guide funnel 4 will be affected by variable forces due to a change in the mechanical properties of the soil, they will lead to self-oscillations of the opener at which the slider 13 will move in the guide 9. In this case, the spring 15 will elastically deformed in the longitudinal plane., Axis 8 prevents the rotation of frame 1 in a vertical plane. Auto-oscillations will reduce the coupon resistance of the coulter by 8-10%, eliminate blocking of the coulter and this guide funnel with 4 soil and plant residues, as well as sticking with moist soil, which will make it possible to start spring sowing 3-4 days earlier than usual. . However, such a day gives an increase of at least 1 centner / ha, therefore, it is possible to obtain an increase in yield of grain crops of 3-5 centners / ha. By virtue of the fact that the dimensions of the guide and the leash are commensurate with the cross-sectional dimensions of the disk and the direction of the & . the funnels, the coulters can be arranged in one row for carrying out consistent as well as narrow sowing (in the figures shown, the turning unit for more readable drawing is shown in an enlarged view compared to the times, measures of the disk knife and this guide funnel Formula of the invention The opener contains a leash connected by a U-shaped frame on which a circular knife and a seed guide are mounted, characterized in that, in order to improve the self-cleaning of the coulter from the soil and reduce traction while maintaining the ability to install the coulter in the direction of movement, the leash is provided with a guide with vertical axis, the aP-forming frame has a slider with a groove, and the slide is spring-loaded relative to the driver and installed in the guide so that the vertical axis is located in the slot of the slide. attention during examination 1.
