Description

Square sowing plants are known using marker wheels that serve to drive; the nesting apparatus of the seedling and the simultaneous marking of the locations of the nests of seeds on the floor surface and provided with brake pads for correcting the location of the nests in transverse rows. In the proposed plant, for the purpose of automatic braking of the girder wheels in accordance with the change in the degree of cohesion of the soil along the path of the crop, a coulter was used, mounted on a pivot pole that is connected to the brake shoe lever.

In the schematic of FIG. 1 depicts a general side view of the crop; FIG. 2, 3, 4 - separate parts of the cutter.

In the nesting seeding, the nesting apparatuses are implemented in the form of valves 15 that block the openings of the seed tubes 16 and are connected via a cable to a rotating cam 14, which serves to periodically deflect down the pull of 10 against the action of springs 12 The cam shchiba 14 is driven into rotation not from the sprocket 5 sprocket wheel, but from special marker wheels // located on the sides of the spruce and equipped with clips 13, which serve to mark the places

the location of the nests of seeds on the floor surface. Spurs 13 are located on wheels // so that they sink into the soil in those places where the floor where the sowing of seeds was made. Bringing the valve-slot apparatus into action from the marker wheels, and not from the crawler wheel, is provided for those purposes in order to increase the uniformity of the distance between the seed seats, since, according to the author, the marker wheels of the proposed type are less prone to skidding than the crawler wheels. Sowing machines 9 for seed which serve for directing seeds from 8 to seed tube 16, are rotated, as usual, from the running wheel for 5 seed.

The adjustment of the location of the nests in transverse rows is carried out in a spindle by braking the axis of the marker wheels with the help of brake shoes, which are either activated by hand or by a special automatic device described below. A handheld device for braking the yay of marker wheels shown on the tfig. 2, is made in the form of a pulley 7, a spike sitting on the axis of the marker wheels, and a pad 22 connected to the handle 23 and mounted on the spring 25. By turning the handle 25, the pad 22 presses against the tongue 7, and thereby produces

braking marker wheels and alignment of the location of nests in transverse rows. On the current / FIG. 2 shows a handheld device for lifting the marker wheels, made in the form of a handle 24, carrying, at the end of the worm to 26, which causes the rotation of the gear 27, rigidly connected with the gear 28, moving along the arc-shaped gear frame 6. mounted on pivot arms 4 supporting marker wheels. When the handle 24 is rotated, the gear 28 moves along an arc-shaped gear frame b, as a result of which the rotary levers 4 together with the wheels 7 / up or down.

An automatic device for tormenting the marker wheels / 7 is depicted in FIG. 3. This device uses a coulter / (mounted on a swivel stand — the hole 19 in which the lever 19 is missed, fitted with a spring 20 and connected to the brake pad 19. When the coulter 18 moves in the soil, its stand is depending on the degree of connectivity soil, to a greater or lesser extent, deviates from the vertical position. With appropriate deviation of the rack 18 block 19, with the help of the spring 20 presses "{to the pulley sitting on the axis of the marker wheels. With this device the author believes that it is possible to perform an automatic braking The marker wheels 7 / crop, put in this case, depends on the degree of connectivity of the soil and, therefore, is coupled with more or less skidding of the marker wheels.

h In FIG. 4 shows a device for automatically raising the marker wheels during the races of the crop, as well as during its installation in the transport position. V. This device uses a pivotal double-arm lever 29, connected with an SUSHEM shoulder with a help, and a cable with an automatic device 27 of the usual type, and the other with an arc-shaped frame 5. When the automatic machine 27 rotates, the cable and lever 2Y are rotated, so that the opposite end of the latter rises and moves

upwards the frame 6, with which the axis of the marker wheels is connected. The device connecting the axis of the marker wheels with the arcuate frame b, as already indicated in the description of the manual elevator, consists of two gears 27 and 28 (Fig. 2) mounted on the levers 4 supporting the axis of the marker wheels. The gear 27 is in engagement with the worm 26 of the manual elevator. ,

The arc of the frame 6 moves in the guides 33. In view of joro, that the lever 29 and the levers 4 supporting the marker wheels rotate around various centrifuges, it is possible that the BaHj is wedged; i.e., the frame 6 in the guides 33. To avoid this, the lever of the lever 25 at point 31 has the slot in which the bolt is passed, connecting frame 6 with lever 29.
