Description

The invention relates to agricultural machinery, in particular, to mechanisms for converting to transport belts, and to regulating the depth of tillage of wide-grip hinged sectional agricultural tools.

The purpose of the invention is to improve the performance properties of agricultural implements.

FIG. 1 shows the mechanism, the type of the right lever of the balance carriage, does not begin to affect the left lever 6 of the balance carriage, thereby raising the front wheel 8 above the floor surface; The thrust pad 10 is designed so that when the mechanism is rotated in the horizontal plane together with the vertical axis 4 in the bearings 3, the support wheel 8 freely passes under the frame 1. Thus, the mechanism having two

position of near transport.

To move the gun to the long-distance transport position, the tractor driver turns the side sections over the central section in the horizontal plane (not shown). At the same time, the mechanism with one support wheel, like a conventional vane, is rotated 90 ° along with axis 4 in bearings 3 and

ku working position; in fig. 2 - the same, the support wheels in the working position, with the transport position. The recess becomes automatically one transfer mechanism in the transport mode. In this case, the tool is transferred to the position and adjustment of the tillage depth of the agricultural tool includes frame 1 with a vertical bracket 2. Vertical axis 4 is installed on frame 1 and bracket 2 in bearings 3 and frame 4 is connected to hinge 5 by means of hinge 5. levers 6 and 7. The hinge 5 is installed at the junction of the levers 6 and 7. At the ends of the levers 6 and 7, the support wheels 8 and 9 are fixed at a certain radius, supporting wheels 8 and 9 are fixed. 8 and 9 form a balance car netku. The lever 7 is provided with a thrust pad 10, a screw pair 11 and a bracket 12 in which groove 3 is made. On the vertical axis 4, the fixed part of the hydraulic cylinder 14 is pivotally fixed, the rod of which is connected to the bracket 12 of the lever 1. The frame 1 is also fixed to the working bodies 15.

The mechanism for converting the tillage depth of the agricultural implements to transport positions works in the following way.

In the process of operation (Fig. 1), the support wheels 8 and 9, located on the levers 6 and 7 of the balance carriage, roll over the uneven surface of the floor, smoothing them, which significantly improves the stability of the stroke of the working bodies 15 at a predetermined processing depth. The depth of travel of the working bodies 15 is adjusted by a screw pair 11 by changing the angle between the levers 6 and 7 of the balance carriage. So that the hydraulic cylinder 14 does not impose restrictions on the longitudinal-angular oscillations of the balance bar 30

Noah carriage in the bracket 12 provides a groove 13.

At the end of the work, the tractor operator puts the hydraulic cylinder 14 into operation, the rod of which is mixed in the groove 13 of the bracket 12 and selects all the gaps. Then, I will act on the first lever 7

The position in the horizontal plane, perpendicular to the direction of movement of the unit. When the machine moves, the bearing vane wheel is oriented in the direction of movement.

To move the tool into the working position, the tractor operator performs all the operations indicated above in reverse order.

The effectiveness of the invention lies in the possibility of using paired wheels on the balance carriage to create wide-grip articulated sectional cultivators-flat-cuts, which improves the stability of the tool working bodies at a given depth of processing, which in turn increases the yield of grain crops.
