Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to improve the uniformity of multi seeding. The sowing machine contains a hopper 1, a frame 2 with a chassis, coulters 3 with a parallelogram suspension 4, a V-shaped trench formed by an inclined-mounted conveyor 5 and a fixed wall 6. In the wall there are stepped downstream windows, to which are connected the funnels 8 and sem wires 9. The lower edges of the sowing windows are beveled to the direction of movement of the conveyor belt. Seeds from the hopper 1 enter the V-shaped groove and as the conveyor belt 5 moves, they flow through the seed boxes into this wire 9 and then into the furrow. Due to the inclined position of the conveyor 5 and the wall 6 and the sloping seed windows, the seeding uniformity increases. 5 il. with S (L

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to sowing machines for grass seeding,

The aim of the invention is to improve the uniformity of multi seeding.

Fig. 1 is a diagram of the sowing apparatus for small seed crops; FIG. 2 is a view A of FIG. 1; Fig. 3, node I in FIG. 2; FIGS. 4 and 5 — sowing unit, possible arrangements,

 The sowing machine for small-seed crops consists of a seed bin 1, a frame 2 with a running gear, coulters 3 with a parallelogram suspension 4 and a metering device, which is made in the form of a V-shaped groove formed by a moving endless belt of the conveyor 5 and a fixed wall casing 6 in which the rows of sowing windows 7 are made. To the sowing windows 7 are connected funnels 8, connected by sem wires 9 with openers 3, Sowing windows 7 are made step-down in the direction of movement of the endless belts 5, Exhaust edges 10 you Seed windows 7 are beveled in the direction of movement of the conveyor belts.

The sowing unit can be made with the location of the bunker in the middle part (Fig, 4) or bins at the ends of the conveyor (Fig, 5),

The sowing apparatus for small seed crops works as follows

Seeds of crops sown in the bunker 1 come into a V-shaped chute, one side of which is made movable in the form of an endless moving conveyor belt 5 and the second in the form of a fixed wall 6. movement from the support wheels, spreads out the seeds under the bunker 1 from the initial height of the seed hill up to the outlet of the bunker with a constant lower

By adjusting the height of the knoll as it moves from its place of supply to the U-shaped chute to the ends of the conveyor (Fig 4) or vice versa (Fig. 5), the sowing windows 7, made in the fixed wall 6, provide sowing of seeds from the apparatus . Since the profile of the hillock of seeds when the belt 5 moves from the point of supply to the V-shaped groove decreases, the sowing windows 7 of the wall 6 are also made stepwise-lowering, which ensures continuous sowing of seeds at each sowing window, to ensure evenness of sowing Seed and waste edges 10 of the sowing windows 7 are made beveled towards the direction of movement of the conveyor belt 5.

Thus, as a result of the work of the sowing apparatus, a multiply ordered stream of sowing seeds is formed, which flow through this wire into the groove formed by the open joint 3. As a result, the seeds of small-seed crops are evenly sown in the groove with the required seeding rate.

The use of the present invention allows for multiuniform seed sowing of small seed crops with the required seed rate, which leads to savings in seed material and higher yields.
