FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to salines for regular sowing of agricultural crops.

The purpose of the invention is to reduce energy consumption and improve operational reliability by braking gears.

FIG. 1 shows one section: a cut, top view; FIG. 2 is the same side view; in fig. 3 is a diagram of the interaction with the soil of a toothed disk knife during its movement with braking (slipping),

The proposed crop (Figs. 1 and 2) includes a frame 1, on which support-driving wheels 2 are installed, gear disc knives 3 and double-disc coulters 4 mounted along (toothed out gear disc knives 3, if you look in the direction of translational movement The frame I is equipped with a transverse shaft 5, to which, by means of connecting rods 6, the shafts 7 and 8 of the battery with serrated disk knives No. 1 are hingedly attached 3. The knives 3 in the battery x are attached to shafts 7 and 8 rigidly. and 8 mates with shaft 5 chain drives 9 and 0 “Shaft 5 in turn is matched with chain ereda- i1 whose wheel axle 12 2.

The dp of ensuring the lay down ratio (slowdown) of 1.2-5.0 gear ratio of chain transmissions 9 1I from shaft 7 to axis 2 and chain transmissions 10 and 11 from shaft 8 to axis 12 should be equal to 0.45-1.875. The serrated circular knives 3 (Fig. 3) are made with teeth 13. The working faces 14 of teeth 13 are set to adjust the angular velocity of its rotation of the disks 3 and tilted into the inside of the disk 3 at an angle of 0-30 to its radius 15 through the apex of the tooth 13 ,

Shafts 7 and 8 (Figs. 1 and 2) by means of telescopic rods 16

with frame 1. Bars 16 are spring-loaded with pin 17,

In the working position, the seed weight moves in the V direction. Part of the weight of the seed is transported through frame 1, telescopic rods 16 and springs 17 on one side and through frame 1, shaft 5 connecting rods 6 on the other side are transferred to shafts 7 and 8 of the disk batteries and consequently, on the toothed disks 3, which are pressed against the soil and interact with it. The gear discs 3 do not roll freely over the soil, as they are connected via shaft 7 and 8, chain drives 9, 10 and 1 to axis 12 of the support wheel 2. Circumferential speed Vg of the end of tooth 13 (Fig. 3) of disk 3 1.2-5.0 times less than the translational speed V selkio The absolute speed Va of the end of the tooth 13 is determined by the vector sum of V and Vg and in the process of interaction with the soil has a direction to the side. Therefore, when the disk 3 slips, the working faces 14 of its teeth 13 interact with soil as a dihedral wedge with a positive angle of entry into the soil and vertik The main component S of the soil resistance forces is directed towards the deepening of disk 3; the Z value is determined from the vector relation

Z R - X,

where R and X are, respectively, equal to each other, and a and horizontal are the components ciiFi of soil resistance to deformation by a disk.

Moving along the rod I6 the point of attachment of the end of the springs 17 regulates the degree of compression of the springs 17 and, consequently, the force of pressing the discs 3 to the ground.

In the grooves formed by the toothed discs 3, seeds are sown by double-disc coulters 4 mounted along the track of the discs 3.
