Description

The invention relates to agricultural machinery engineering, in particular, to sowing machines producing a variety of sowing seeds of grain crops.

The purpose of the invention is to increase the field germination of seeds by uniformly distributing them in depth.

FIG. 1 shows a schematic representation of the proposed planting arrangement, side view; in fig. 2 - the same, top view.

The device contains a coulter 1 with an obtuse angle of entry into the soil, consisting of an arm 2 with elongated cheeks 3 and this wire 4. The leash 5, rigidly connected with the coulter 1 by means of bolts 6, makes a double-shouldered lever with a regulator 7, and form between them a blunt (approximately 135 °) angle. The double-shouldered lever (5 and 7) is pivotally mounted on the axis 8 of the driver 9 of the incoming roller 10, and the depth controller 7 is connected to the stop 11 via an extension spring 12. In the alignment of the cheeks 3 of the coulter 1 there is a press roller 10, which sits on the axis 13 of the driver 9, the second end of which is pivotally connected to the axis 14 of the frame 15. spring 17 and adjustment holes 18.

The device works as follows.

During movement of the plow and the furrow-forming working bodies, the opener 1 4) ascaps the furrow

(2 times

40 mm wide, In the boro-E-du opened by him, through this wire 4, seeds are fed, which are pressed into the soil coming from behind at | : At yatkom 10,

installed in the alignment of the elongated cheeks 3. At the same time, under the roller, the soil is squeezed, the density of which can be changed by the pressure spring 17, moving it through the holes

18 rods 16. The elongated cheeks 3 of the opener 1 prevent the furrow walls from shedding when the seed is pressed into the ground with a roller. The width of the roller 10 is somewhat larger than the diameter of the wire of wire 4, and its close interposition with the roller eliminates the rolling of seeds along the groove. The furrow is further opened up and filled up with loose, moist soil due to the shedding of the walls, as well as with a chain loop used on modern bays.

The coulter suspension provides a constant value for the burial force acting on the coulter 1 when it vibrates on uneven ground, by setting the depth adjuster 7 and connecting it. with the support 11 of the leash 9 through the extension spring 17. As a result of this arrangement between the coulter suspension and the roller, the depth of the furrow remains constant regardless of the changing soil microrelief and its physicomechanical properties. The size of the opening of the furrow is changed by the action of the depth adjuster 7 on the degree of stretching of the spring 17.
