Description

In the proposed chess plant, the adjustment of the location of the nests of seeds in transverse rows is carried out with the help of pegs stuck into the soil at certain distances from each other and interacting with a special lever associated with the transfer to nesting apparatuses made in the form of drums. .

In the schematic drawing of FIG. 1 shows a general view of the seed above; FIG. 2.-general side view of the nesting apparatus; FIG. 3 and 4-transfer details; FIG. 5 and b is a general view of the device for inserting rings into the soil; FIG. 7 is a general perspective view of a comb for pulling pegs from the soil.

Each nesting machine of the crop is a drum / ((into which the seeds are loaded). The drum 10 rotates on a fixed axis 7, to which a disk B with a protrusion I is fixed downwards is rigidly attached. To push the seeds out of the drum cavity into seed tube 1 pistons 2, the rods 3 of which are provided at the ends with rollers 5 and mounted on springs 4. When the drum rotates, the rollers 5 of the rods 3 abut against a fixed protrusion P, as a result of which the pistons 2 throw seeds into the tubes / and further into the openers 15. Drums 10 with (196 )

water is rotating from the drive shaft of the tractor. For these purposes, a shaft (b) is installed in the front part of the cutter, which is connected with the cardan shaft 18 of the tractor by means of a pair of conical gears. The gear / of this gear sits on the shaft 16 freely and receives continuous rotation from the drive shaft 18. The gear / is rigidly connected to the gear with a tube 28 (Fig. 4). Between the gears / and // on the tube, a gear /// is mounted with a movable stop 29. Gear IV is connected by a chain drive with the gear 19 attached to the drum 10. On the tube 28, a lever 30 is pivotally mounted, fitted on the upper end 32, and on the lower end is a spatula 31, which, when the peg is driven into the soil, rotates the lever 30, which in turn displaces the abutment 29, as a result of which the teeth 111 and IV are connected with each other by means of a spring-loaded dog 36 and rotate together. When the pawl 36 is collapsed under the action of a spring between the teeth of the teeth II, the latter connects to the teeth ///, as a result the shaft / b receives rotation and in turn transfers the rotation to the drum 10. The teeth 19 of the latter are rigidly connected to the teeth V, which by means of a chain transmission transmits rotation to the gear ///. At that moment,

when the stop 29 pulls the dog Wb away from the teeth of the teeth / 7, the drum 10 stops rotating. During the reverse movement of the stop 29 under the action of the protrusion 32 of the lever 30, the dog 36 again engages the teeth of the teeth //. Dimensions of the teeth /// must be calculated in such a way that it makes one turn at several turns of the drum 10. After several turns of the drum 10, the stop 29 will lift the pawl 36 and the gear on the drum 10 will be turned off, as a result of which its rotation will be suspended. The drum is put into operation at the moment when the stop 29 will be retracted by the lever 30 and the dog 36 will again link the teeth // and IV. Thus, the operation of the drum 70 is performed at specific locations of the site in accordance with the location of the pegs.

A device made in the form of a lever 37 pivotally attached to the frame (Fig. 5, 6) mounted on spring 39 and carrying spring-mounted plates 43 at its downward-curved end for clamping pegs was used for inserting pegs into the soil of the spike. When the lever 37 is moving, under the action of a rotating figured cam, between the plates 5, the peg 25 is driven into the soil. A comb 24, fixedly attached to the frame, was used to push the pegs out of the soil in the spreader.

The subject matter of the invention.

Claims (4)

1. Chess-sowing crop with nesting apparatuses made in the form of drums, equipped with pressures for pushing out seeds and driven from the cardan hall of the tractor, characterized in that for periodically switching off the gear to the sowing drums, for the purpose of automatic correction arrangement of the nests of seeds in transverse rows, a movable stop 29 is used, located on the /// gear and designed to raise the dog 36, which connects the teeth P and IV, of which I have been installed with the possibility of free rotation on the shaft (b) is brought into continuous rotation from the tractor's universal drive shaft, and gear IV is rigidly fixed on the shaft 76, transmitting the rotation to the sowing drums and at the same time releasing the teeth ///, bearing the stop 29. 2. The form of making the crop according to claim 1, characterized in that for moving the stop 29, 8, the dog has 36 teeth // and IV is freely suspended on the tube 28, the lever 30, periodically deflected by the pegs 25, stuck in soil at a certain distance from each other. 3. In the village of PP. 1 and 2 use a device for sticking pegs into the soil, characterized in that it is made in the form of a lever 37 hinged to the frame, carrying spring plates 43 for clamping pegs 25 and driven by a rotating figured cam 40. 4. In the village of PP. 1-3, use of a device for pulling the pegs out of the soil, made in the form of a comb 24, fixedly mounted on the seed frame. Shig sigz 4 /% hp Have .fig5
