Description

Ate 1 The invention relates to agriculture, in particular to a device for anti-erosion sowing of grain crops on slopes. It is known a wellbore-forming device containing multi-cavity wheels, freely mounted on horizontal axes, which are mounted on the frame with alternating even and odd number of blades. The disadvantage of this device is the formation of small holes that, after several irrigations, decrease in volume, and wash off grains, increased soil erosion and increased yield. The closest in technical essence and the achieved result to the proposed is a device for sowing agricultural crops along furrows, which contains frame furrow cutters with openers located at the rear and symmetrically to its longitudinal axis, connected to this C2 wire. A disadvantage of the known devices is the formation of a continuous groove, which contributes to soil erosion on the slopes. The purpose of the invention is to prevent water erosion by cutting out discontinuous furrows and increasing yield. This goal is achieved by having a frame for cutting, a furrow cutter with soschniki connected to the wires symmetrically to its longitudinal axis, equipped with a crank-connecting mechanism , in the connecting rod of which a through longitudinal groove is made, at the same time the furrow cutter is rigidly fixed on the connecting rod, and this wires are placed in its groove and have a stop located on the connecting rod, which is spring-loaded relative to the frame. FIG. 1 shows a seeding device, side view; FIG. 2 the same, rear view; Fig, 3 is a diagram of the device in the lower position of the furrow cutter, side view; in fig. 4 the same, with the upper position of the cut furrows. The device consists of a frame 1 on which a curvature-knee mechanism is mounted. The crankshafts 2 and 3 40J of the latter are connected with the help of connecting rods 4, on which the furrows 5 are rigidly fixed with symmetrical dumps. On the frame 1- there is a fixed board 6 fixed on which rigid tubular openers 7 are mounted in pairs. The rigid sem wires 8 of each pair of SOP1NIKS 7 are interconnected, and on top they are connected to a bunker (not shown) by means of flexible pipes 9. guide bushing 10. At the upper end of each pair of sem wires 8 openers, a support pin 11 is installed, which is also the opener travel regulator. Each pair of wires 7 passes through the longitudinal groove 12 of the connecting rod 4. On each pair of wires, a compression spring 13 is installed, the lower end of which rests on a ring 14 fixed on the wires. On each ring 14, a stop is fixed in the form of symmetrical rollers 15, which are in contact with profiles 16 fixed on the connecting rod 4 in the area of the groove 12. The device operates as follows. During the forward movement of the slurry, the crankshaft 2 (or 3) receives an intermittent rotary motion, while in the working process the shaft knees are in a vertical plane. In the lower position of the knee, the furrow cutter 5 cuts into the soil to a depth H, and each tubular coulter 7 to a depth H, which is approximately 0.5 N (Fig. 3). In this position, the seed wheel moves forward a distance equal to the furrow length (or jumper), after which the crankshaft rotates 180 ° and stops in this position. With this rotation, the columnar shafts 2 and 3 of the knee, which are in the lower position before, take the upper position and vice versa (fig. 3 and 4). The furrow cutter 5, which is rigidly mounted on the connecting rod 4, rises by the value H and takes the position shown in Fig. 4. When the furrow cutter leaves the soil, its tip is from the soil surface at a distance of LD and the furrow formation stops. Furrow cutters mounted on the connecting rods of the lower knees, at this moment form the furrows. During the 3 rotations of the shafts 2 and 3, the connecting rods 4 make a plane-parallel movement, contact with the profiles and lift the ring and the coulters 7 up and up. The openers keep up vertical position. The course of each coulter H (equal to the stroke of the limiter and due to the distance between the rollers 15 and the top point of profile 16 (HS, Fig. 3 and 4). When lifting the coulters, the spring 13 compresses and ensures constant contact of the rollers 15 with the profiles 16. Thus Thus, in the upper position of the connecting rod, the tip of the furrow cutter is above the soil surface, and each of the pair of coulters is deepened by the value of Hg. 4 rotates 180 in the direction shown in the diagram. The crank is lowered by inserting a furrow cutter into the soil. Simultaneously under the influence of its own weight and force of the spring 13, the coulters pair is also lowered by N. sleeves 10. As a result, the furrow cutter goes deeper into the soil by the amount H, and the vomer on H, results in continuous sowing of seeds and staggered furrows with a constant sowing depth. The use of the proposed device will completely eliminate the soil washout. The implementation of intermittent furrows, which have a larger volume than the known ones, will increase the soil moisture, which contributes to an increase in plant growth and an increase in yield by 25%.
