Description

At the beginning of plowing, when laying the first furrow, both wheels go on virgin soil and in order for the plow to go horizontally, they must be raised to the same height. Since the first b (5 beams are usually plowed smaller than the normal depth, when plowing the second furrow to the normal depth, the left wheel going on virgin soil should be raised to a height equal to the normal plowing depth, and the right (furrowed) going along the laid shallower than the first furrow, should be raised by the difference in depth of the 1st and 2nd furrow. When plowing the third and subsequent furrows, the left wheel, going along virgin soil, should be raised to a height equal to the normal depth, and the right (furrow), as going along the furrow is already normal th depth, should remain in the plane of the blade of the plowshare, when plowing it is desirable to have three types of lifting wheels: 1) uniform lifting of both wheels, necessary when plowing the first furrow; 2) the lagging of the furrow wheel with respect to the left, necessary for plowing the second furrow; 3) lifting only the left wheel, necessary for the third and subsequent furrows.

The axle a of the left wheel A, traveling on virgin soil, is fixedly connected with the shoulder b,

rotates in the bearing i the leash With the hinges Q d connects the arm b with the rotary lever //, having a point: the rotation is fixed on the frame 3. The axis e of the furrow (right) wheel running along the furrow, is fixed in bearing L. The lever, having the form of a hook, is connected by a hinge. t to the knee / and can be thrown over the hinge 3, fixed in the frame, at / on the fingers 1 or 2 of the lever H,

When plowing the first furrow, setting a cavity at lever M on finger 1, while rotating the lever // in the direction of the arrow “, we get the greatest rise of the furrow wheel B, equivalent to lifting the wheel L, i.e. both wheels A and B are raised uniformly by the same height; as the lever H is rotated in the direction of the arrow, the reverse movement will occur and both wheels A and B will lower and lead the plow out of the furrow to the transport position. When plowing the second furrow, setting the notch at the lever / W on the finger 2, while rotating the lever ff in the direction of arrow a, we obtain a reduced lift of the furrow wheel B, equal to the difference in depths of the 1st and 2nd furrow, i.e. - the left wheel L rises normally, and the right B lags behind. As the lever rotates, in the direction of the arrow, the left wheel of the wheel starts to fall. I ha, rotate on

bolt 1 and sliding its notch X along the pin M fixed in the lever, push it into it and release the lever Ж with the finger 2, which rests against its back i finger 3, under the action of the pin R, the pressure on the hinge will slide. The furrow wheel will also lower and the plow will exit the furrow to the transport position. During the reverse rotation of the lever H, the lever M with its weight automatically captures the notch at the finger and the plow will be in the working position. When plowing the third and subsequent furrows, having thrown the lever M on the fixed finger 3, we lock the furrow wheel B; when the hub of H rotates along the arrow, only the left wheel A rises. When the lever H is rotated along the arrow p, the mechanism will move, similar to the previous one, i.e. m ha P will release the lever M from the finger 3, which will be pressed against the bolt O with a back and, under the action of the puller R, will start sliding: press and press the hinge t. Both wheels

empty, l will bring the plow out of the furrow to the transport position. When the lever H is reversed, the plow will automatically return to the working position.

The subject of the patent.

A lifting mechanism for frame plows, characterized in that the knee / axis of the pivot wheel B is connected to the lever H swiveled near the hinge 3 by means of the lever M, the pn finger of which serves to attach the hinge to it, provided with a slot. X, ti p and pit and J is designed to clutch it with one of the fingers 1.2 to 3 levers ff, in order to communicate to the tandem wheel the lifting speed, respectively, equal to or less than the speed of the vertical movement of the field wheel, or for fixed installation the first wheel in the plane of the bottom of the furrow when the lever // is turned counterclockwise.
