SU101165A1 - Adaptation to nesting slabs, working from knot-gauge wire, for changing the magnitude of the intergeds in rows - Google Patents

Description

The nested seams operating from the knotted wire are not designed to change the magnitude of the interglands in rows equal to the pitch of the wire nodes interacting with the seeding catcher. This reduces the versatility of the seeds and is the reason for their use only for sowing crops with the same and constant magnitude of the interglands in rows.

The peculiarity of the proposed adaptation to nesting forks is that, in order to provide the possibility of changing the magnitude of the interglands in rows at a constant pitch between the nodes of the wire, in the transmission from the knotter to the seed cells of the spike detachable cams, turning the ratchet bristle from the dog mounted on the catcher.

FIG. 1 is a schematic side view of the device; in fig. 2 view from the front.

Movement from knotted wire 1 and catcher 2 is transmitted to its sowing organs in a device using a disk 5 with detachable jaws 4 attached to the disk on one side. The disk is made in the form of ratchet pinion with teeth 5, for periodical rotation of which a doggie 6 is used, pivotally mounted on the lower end of the catcher 2 and adjacent to the teeth of the disk from above. The disk is pivotally mounted on an axis 7, cantilever-mounted on a bracket 8 attached to the frame of the cutter and carrying the dog 9, which interacts with the teeth 5 and prevents the disk 3 from being randomly rotated in the opposite direction to the feed of the dog 6.

On axis 10, which is cantilever-mounted on bracket S, is mounted a lever 11, which interacts with the cams 4 and is connected by a pull 12 with the lever 13 of the square shaft 14 of the SS-6 type, which controls the operation of the seed metering machines. The levers 15 of the shaft 14 t gami 16 are connected to the valves 17 of the openers 18 of the chain.

With a constant pitch, the mechkud wire nodes / fixture make it possible to vary the magnitude of the interglands in rows by changing the number of cams 4 attached to the disk 5 with one or another pitch between them.

If, with twelve cams on a disk, the magnitude of the interglacial distance in a row is equal to the pitch between the wire nodes /, for example, 70 cm, then if the cam is removed from the disk through one six cams //, the lever will be turned one. For two teeth feeds 5 by the pawl 6 and the magnitude of the interglands in the order is doubled and will be 140 cm. With four cams 4 on the disk 3, the value between the pairs is 210 cm, and with three cams 280 cm.

To dry square-nesting seeding, the coulters of the crop are installed with a distance between them equal to the size of the inter nest in rows.

The presence on the mill of the described device allows to expand

spraying for a variety of crops and shedding melons, cucumbers, zucchini and other crops in a square-nesting way.

Subject invention

Adjustment to the nesting shells, working with them from the knot-gauge wire, to change the magnitude of the interglands in rows, characterized in that, in order to ensure the possibility of this change at a constant step size between the wire knots, in the transmission from the catcher to the sowing organs, a disk with a variable pitch between its detachable cams, turned by the ratchet gear from the pawl mounted on the catcher, is applied.
