SU13377A1 - Differential lifting mechanism for plows - Google Patents

Description

In the well-known two-legged lever plows, you have the disadvantage that the field wheel, with its weight during plowing, plows the plow towards zero (but the plow is moving to the left) and the plow, due to this, cannot go smoothly, fluctuating from the topography of the soil.

In order to eliminate this drawback in the differential lifting mechanism, a clutch is used, allowing zak; The axis of the furrow wheel is immobile both during the transport of the plow and during plowing, whereas the axis of the field wheel can only be fixed during transport.

In the schematic drawing of FIG. 1 and 1 depict the specified coupling in two projections; FIG. 2 — equipped with the proposed lifting mechanism — a plow mounted for operation; FIG. 3 - the same plow installed for transportation: FIG. 4 and 5, respectively, the location of the parts of the lifting mechanism in both cases marked; FIG. 6 and 6 - a detail of the mechanism; FIG. 7-part plow frame.

Coupling X (Fig. 1) of the differential lifting mechanism for plows is equipped with: a) a rocker groove for the finger L of the crank 2) the axis of the furrow wheel (Fig. 4); b) a fist g serving as a stop for the crank j) when turning the coupling on the finger B (Fig. 6) with

ti F from the lever H (Figs. 2 and 3), n c) with a lever, near the hinge E, lever D, D which is intended to be pressed against the ledge Ж of the axis and the field wheel when raising the plow. For raising the latter, a groove groove a is provided (fig. (I), which serves to guide roller 3 (php. 1) of lever D, and located in the tide of pad Y fixed on the plow frame (Fig. 6), fitted with an opening to it to reinforce pin B and a hole for maintaining the axis of the furrow wheel. Fig. 7 shows a part of the plow frame with the arrangement of the axes during plowing.

To raise the plow while moving the lever H to the extreme position shown in FIG. 3, the clutch will rotate in the same direction and the crank pin L at the axis of the furrow wheel will begin to slide along the rocker groove a, while the fist z will be pressed to the crank p, due to which the furrow wheel will begin to approach under the plow, and the latter will rise from the ground . While the coupling X is moving, the finger 3 of the lever D will also begin to slide along the groove of the cover plate U. From half a turn along this groove lever C with its shoulder D will be pressed into the axis of the field wheel and press it to the protrusion G-. From this point on, the zero wheel will begin to abut the ground and also contribute

To lift the plow up and out of the ground. When lever H takes the position shown in FIG. 3, the wheels will come together and the plow will be ready to be transported. When the lever is reversed, the wheels will begin to diverge in different directions and the legs will assume the position shown in FIG. 2

The subject of the patent.

Differential lifting fur, low for plows, characterized by the use of a coupling g, equipped with: a) a slipway for finger L of a crank

axes of the wheel wheel, b) with a fist g serving as a stop for the crank p when turning the coupling on a finger with the help of a pull F from a lever, and c) with a lever D, a shoulder D, which is intended for the lever to the axle and field axis When lifting the plow, for each end of the plow, a rocker groove is used to guide 5 lever D and is flat in the tide of pad J fitted with a hole, to strengthen the pin and hole to support the axis of the furrow wheel.
