Description

2. A crop according to claim 1, about tl and h and rani with the fact that each cassette is equipped with a cellular plate with a groove on one side of it, in which a finger is installed at one end, the other end of which is placed in a direction

track, with a hole in

Each cassette has an oblique cut on the side of the extension. The cassette case has a transverse groove on one side for fixing it in the cassette holder, and

for the passage of a finger. the other side - the longitudinal groove

The invention relates to agricultural machinery, in particular, to breeding plants for large-scale sowing of seeds of agricultural crops. The known breeding selection, containing a frame, a bunker in which hollow body cassettes with openings are installed, a guide track, a cash register feeding mechanism and coulters DG 3 The disadvantage of the known selection is that in sowing the second stage of the selection process The works are laid in rows parallel to the passage of the unit. With this arrangement, the samples to be tampered are unequal with respect to adjacent tracks. Uneven plant development makes it difficult to objectively evaluate variety samples. The purpose of the invention is to provide the same conditions for the development of a plant by sowing seeds of variety samples in rows across the planting pass. The goal is achieved by mounting cassette holders on the selection box on the coulters, which are fixed to the frame by means of an endless chain conveyor at an angle to the longitudinal axis of the cutter, while the cassette feeding mechanism is designed in the form of a spring-loaded two-arm lever, one shoulder of which is located in the zone of the hopper for feeding the cassettes into the cassette holders from it, and the other shoulder is curved to interact with the coulter, the guide track being in the form of eskonechnogo closed loop ML to the branch which is oriented parallel to the upper branch of the endless conveyor, and the other - in gorizonTsshnoy plane at an angle to the lower branch of the conveyor. In addition, each cassette is provided with a honeycomb plate with a groove on one of its sides, in which one end is mounted with a finger, the other horse of which is placed in the guide track, and the hole in each cassette on the extension side of the cellular plate has an oblique cut, the cassette case, on the one hand, has a transverse groove for fixing it in the cassette holder, and on the other hand, a longitudinal groove for the passage of fingers. FIG. 1 shows a selection plant, rear view in FIG. 2 the same, top view; in fig. 3 - loading device, top view; in fig. 4 shows section A-A in FIG. 3 in FIG. 5 - movement mechanism. cell cassette plate; 6 is the same, top view; in fig. 7 - cassette, bottom view; in fig. 8 - the same, top view. Breeding plant consists of a frame. 1 with supporting wheels 2, on which is mounted a gearbox 3 with a V-belt drive 4 for driving four sprockets 5 with harnesses; On them are two endless / sht 6 chains forming a conveyor on which the coulters 7 with cassette holders 8 are fixed. In the longitudinal: grooves 9 of the cassette holders 10 fingers are installed, the outer ends of which are located in the curved track 11; rigidly mounted on shafts, set-; lenny in ball bearings; 12, which can move relative to the frame for tensioning the chains 6. On the frame of the cutter there is a hopper 13 for charged cassettes and a bunker 14dp, empty cassettes, under which a rod 15dl of ejection of empty cassettes from the cassette holders is fixed on the frame. In order to prevent the bend chain from bending, when cutting furrows, the openers 16 are mounted above the lower branches of the furrows, rigidly mounted on the frame of the cutting frame. The feeding mechanism of the cassettes 17 for grabbing them by the cassette holder 8 consists of a two-armed lever 18 which is spring-loaded relative to the frame and which is mounted on an axis of rotation 19 fixed on the frame of the cutter. AT ; the lower shoulder of the lever 18, which has a pro-i longitudinal groove, freely enters the cylindrical end of the finger 20, which

The collar is inserted into a specially profiled groove on the bottom of the hopper of the charged cassettes. The second end of the finger 20 goes into the hopper and serves to extend the lower end of the cassette out of it. The other lever arm is made straight to interact with the vomer 7..

The cassette consists of a housing 21, a cellular plate 22 inserted into it, and a spring 23 for fixing the latter.

The case has a hole 24 and several slots. Hole 24 is designed to eject seeds from the cells, and its oblique cut ensures uniform seed deposition from the plate cells. The groove 25 is intended for fixing the cassette case with a pin 26 above the barrel. in a certain position when its apertures 24 are located above this seed opener nozzle. The groove 27 is intended to slide the finger 10 into the cellular plate 22 and drive it when moving the plate. The mesh plate is a rectangular, trough-shaped container divided by partitions 28 into separate rectangular cells. In the front part of the plate there is a groove dc drive with its finger 10.

Selka works as follows.

When forming a breeding nursery, the seeds are laid in the cells {Plates 22 at the rate of the required seeding rate. The filled honeycomb plate 22 is inserted into the housing 21 where it is fixed by a spring 23. The charged cassettes are stacked in blocks and stored until sowing. During sowing, the loaded cassettes are loaded into the hopper 13, turn on the tractor's power take-off shaft and start moving . l

When the coulter 7 moves on the upper branch of the conveyor, it deflects the arm of the upper arm 18, which by the lower end pushes the cassette out of: the hopper 13 through the pszac 20. When the cassette holders are in the cassette holder, the pin 26 enters the groove 25 of the housing 21 / and the palei 10 - into the groove 27 of the cellular plastic, and this emitting hole. The hole 2 4 of the housing 21 is aligned with this opener of the opener 7. Insert the cassette into the cassette holder

it is fixed, and the lever comes off the coulter and, under the action of a spring, is set to its original position, corresponding to the grip of the next cassette. Next, the cassette is removed from the hopper, and the next one is replaced in its place, and so on.

On the lower branch of the conveyor, the sonic enters a predetermined depth into the soil and forms a furrow. During this period, the finger 10, moving in the lower part of the guide 11, moves along the groove 9 of the cassette holder 8 and moves the cellular plate 22 above this seed ejecting hole of the housing 21. At the same time, the seeds shifted by the long side of the neck, slid to the oblique cut of this ejection hole and fall into the coulter as it passes over the oblique cut.

At the time of the beginning of the coulter, all seeds are ejected from the cell plate. Upon further movement, the coulter moves from the lower position to the upper finger 10, carried away by the guide 11, moves along the groove of the cassette holder in the opposite direction and pushes the cellular plate into the holder, where it is fixed by the spring 23. Next, the cartridge 17 abuts the rod 15, turns around cassette holder 8, comes out of it and falls into the hopper 14. The opener without a cassette is ready to capture the next cassette from the bunker and repeat the new cycle.

As a result of the addition of the translational movement of the unit and the relative movement perpendicular to the direction of movement of the unit, the angle between the direction of movement of the unit and the direction of movement of the traction chain is determined by the formula:

OS

and sinfts-tt-f

where VQ, is the speed of the unit;

V - relative speed

chains.

The use of the invention makes it possible to place the seeds of the test samples in a row, perpendicular to the aisle of the plant, and thus create the same conditions for the development of seeds.
