Description

The present invention relates to square and stag sowing machines with valve-type nesting devices actuated by eccentrics, marker pads for forming recesses in the soil, and rollers serving to activate the nesting devices during their rolling along the grooves in the soil.

In FIG. 1 shows a general view of the seed above; FIG. 2 is the same side view; FIG. 3-side view in section along the line AB (Fig. 1); FIG. 4, 5 and b-parts of the plant.

In the front part of the cutter on the brackets / shaft 2 is installed. On this shaft eccentrics b are fixed at one or another distance from each other, which are connected with valves 4 placed in the outlets of the joints 3 and held in a closed state with by means of springs 5. At each shaft rotation, the eccentrics turn the valves and open the seed access to the soil. To bring the shaft 2 into rotation, a gear 7 is installed on it, which has teeth only for 8 of its circumference (Fig. 5). From the rest of the circumference of the serration, instead of the Yomesch teeth, the rollers 8, as a result of which the chain I-- binds the gear 7 with the serrated W mounted on the right running wheel of the seed drill,

can slip along the rack 7 without rotating it. The sleeve 7 of the teeth 7 is rigidly connected with a set of gears 77 with a different number of teeth located along the entire circumference of the gears. These gears are used exclusively during the first pass of the crop and can move along the shaft 2, whereby the gear ratio in the chain transmission can be changed and the speed of rotation of the shaft 2 reduced or increased. There are stops 72 on the shaft 2, which, resting against the stops 75 mounted on the springs 33, keep the shaft from rotating. To rotate shaft 2 at some angle when separating stops 72 and 75, rollers 6 are used, mounted on springs 77 and resting on cam 75 rigidly fixed on shaft 2. Cranks 75 are fixed to ends of shaft 2 and connected with marker paws 2 (which serve to mark on the soil surface the locations of the nests of the seeds. On these marks, during subsequent passes of the spruce, alignment of the nests is carried out in transverse rows. The leads of the marker paws are hinged to the brackets 27, which are fixed on the ends of the channel 22, pom in the same channel bar, there is a seat 25. There is a steering wheel 24 in front of each seat,

connected to a bent pipe 25, to the end of which are attached the points 2o and 28. The ridge 26 is mounted on a leash 26a rigidly attached to the axis 27, which is the axis of rotation of the leash 28a carrying the padding 28. Katochek26 is a support and rolls on a flat surface , serves to keep axis 27 at a constant distance from the soil surface. The lead 25a of the roller 28 is pivoted about the axis 27 and has a spike 29 connected hingedly to a pull 30, passed through the tube 25 cavity. The latter is made pivotally in the horizontal plane with the help of the steering wheel 24. The opposite end of the rod 30 is provided with a finger 3J protruding from the slit-shaped cut-out of the pipe 25. Finger 5 / is connected by a cable 32 with an emphasis / 5, which is pressed against the shaft 2 by a spring 33 (Fig. 6). During the first pass of the spike, the W gear is connected to one of the gear 7, which provides the required distance between the slots in the row. At the same time, the rollers should be raised above the ground, and the stops / 5 should be separated from the stops 72 to allow free rotation of hall 2. The marker paws 20 are actuated both during the first and subsequent passes of the seed. Starting from the second pass, the strips are alternately put into operation by the right or left pair of coils 26 and 28, B, depending on which pair is closer to the previous pass of the chopstick. In this case, the transfer chain must be worn on the gear 7 with an incomplete number of teeth around the circumference. When lowering the rollers onto the soil surface, the anvil 75 moves towards the shaft 2 and stops its continuous rotation. Shreddings roll in the work on tubercles and soil depressions formed by marker paws 20. The transmission chain, running on the rollers of the toothed roller 7, cannot turn shaft 2 until the roller 28 has a tubercle. When ascending the tubercle, the roller 28 will rise and push forward 30, as a result of which the cable 32 will retract the abutment 75 from the abutment 72. The shaft 2, having the possibility of free rotation, rotates under the action of the spring-loaded rollers 76 supported on the cam 75 fixed on the shaft 2 After the shaft is turned by the rollers 6 at a certain angle, the chain link 9 engages the teeth of the teeth 7, as a result of which the shaft 2 makes a full turn. When the coil 28 falls into the soil cavity, the ha 30 moves backward and the stop 72 engages again with the stop 75, and therefore the rotation of the shaft 2 stops; at that, chain links 9 begin to slip along the rollers of the toothed roller 7. Thus, the correct location of the nests of seeds in transverse rows in this cell is ensured by the fact that the nesting apparatus is put into operation when the roller rises on the tubercles formed at equal distances from each other with marker paws 20.

The subject matter of the invention.
