Description

The present invention relates to square and stag sowing machines with valve type jacking devices driven from the running wheel by means of an automaton periodically activated through a system of levers by twin wheels rolling through grooves previously conducted in the direction perpendicular to the cutting direction. In the proposed plant, in order to eliminate the need for making furrows at close distances between each other, several pairs of castors are used that are mounted on rods of different lengths.

In the schematic drawing of FIG. 1 depicts a general side view of the crop; FIG. 2 - the same top view on a reduced scale; FIG. 3, 4, 5 - details of the crop.

A seed box 7 is installed on the frame 3 of the seed plant with the sowing devices 6, which are driven from the running wheel 2. The openers of the 53 seedlings are hinged by means of leads 56 to the front part of the frame. In the sockets 54 coulters, as usual, the seed pipes 5 are lowered with their lower ends. The outlet openings of the coulters are closed by valves 52 connected to rods 60, which in turn are connected hinged to brackets 49 attached to the coulters 55.

The openings of the openers of the coulters are closed using springs 55 attached to the drivers 56. On the shaft 9 there are bent JO arms, the number of which must correspond to the number of coulters. Rings 50 are attached to the lower ends of the levers / O, which cover the thrusts 60. Levers / (dogs 46 46 are hingedly attached to the levers by springs 62, the compression of which is adjusted by nuts 63 (Fig. 3). Dogs are made in the form of two-arm levers one of the arms of this lever is a fork, which includes traction 3} with a stop 72. When the tractor pulls 75 to the right (Fig. 1), the dog 46 turns clockwise, and its end opposite to the fork engages the gear 4, which is driven by the sprocket wheel. and engaging the pawl with the gear 4, it retracts together with the lever W to the right, and the valve 52 opens the opener outlet. Thus, the valve opens the opener opening using the automatically acting above device, periodically triggered by the thrust 75. gear 4 is produced under the action of a fixed stop 77, and by disengaging the dog with the gear the valve takes its

the original position with the help of a spring 55. The end of the thrust rod 13 is pivotally attached to the lever 24 rigidly fixed on the rod 4J. On the same rod 41, levers 25 are installed, which are provided with stops 39 and are connected by cables 36 with two shoulder levers 36 carrying wheels 32. When lowering the wheel 32 into one of the grooves, preliminary held perpendicular to the Span, two shoulders lever 35 fixed pivotally to the axis of the wheel 34j turns at a certain angle and tightens the cable 36; as a result, the lever 25 also rotates, and its anvil 39, engaging with the anvil 40 of the rod 41, rotates the latter as well. When this happens the inclusion in the work nested valve devices. In the initial (vertical) position, the levers 25 are driven by springs 43. The wheels 32 and 34 are installed in pairs on different lengths of the bar 57, which is provided for eliminating the need to create furrows over distances close to each other. Installing shtang 37 carrying wheels 32 and 34, and

coulters 55 to the transport position, carried out by a lever device 20 of conventional type.

The subject matter of the invention.

A square and square seeding crop with valve-type seat apparatuses driven by a running wheel by means of an automaton periodically activated by paired wheels rolling through grooves previously conducted in a direction perpendicular to the course of the cut, different in order to eliminate the need to make furrows at close distances between each other, several pairs were used in it. wheels 52 and 34 mounted on different lengths of shtanga 57, with two shoulders levers 55 carrying wheels 52 at their ends connected by cables 36 to levers 25 rotatably mounted on the rod 41 and serving to turn the latter when the stops 39 vi 40 are engaged x activation of the slot machines.
