Description

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to a chassis for the construction of combined agricultural units.

Chassis for compiling combined agricultural units are known, comprising a frame with a device for connecting it to a tractor, driving wheels, supporting wheels, whose attachment brackets are pivotally connected to the chassis frame and connected to it by a hydraulic cylinder, upper and lower longitudinal tools for hanging the tools.

The disadvantage of such chassis is that for lifting tools into the transport position, mounted on the chassis frame and on the linkage mechanism, there are two independent devices that complicate the chassis design and make it difficult for the mechanic to raise the tools.

In order to provide simultaneous lifting to the transport position of the tools mounted both on the chassis frame and on the linkage mechanism, as well as to ensure the possibility of copying the soil relief in the working position by means of the tools mounted on the linkage mechanism, the support wheel brackets are rigidly connected to each other. with plates, on which the lower longitudinal hinges of the attachment mechanism are hinged, the raising of which to the transport position is provided by their abutment into the surface of the beam.

FIG. 1 shows the chassis in the working position, side view; in fig. 2 - the same, in the transport position, top view; in fig. 3 - the same, side view.

The chassis for compiling the combined agricultural aggregates consists of

a two-section frame 1 having a connector along plane A-A (Fig. 1 and Fig. 2).

The front bar 2 is connected by pins 3 to frame 1 and pin 4 to a hook-on bracket 5 having two pins 6 for fastening it with

lower t hami hitch tractor.

To the rear beam 7, the beam 8 of the rolling wheels 9 is hingedly fastened. The beam 8 has plates 10 for hinging in them

lower nozdolnye t g 11 mechanism of attachment of guns. In the upper longitudinal section 12 and the lower section 11, a rack of 13 guns is fixed, for example, seeds 14.

The cylinders 15 lifting working tools in the transport position is installed between the bar 8 and the transverse bar 16.

In front of the shashi on the longitudinal bars x of the chassis frame body 17 is installed, and

Also the bar 18 of a cultivator is fixed. Rotator cultivators 19 of a rotating type are hinged to the cultivator sections.

The chassis works as follows.

At movement of the unit the cultivator makes preseeding cultivation; the rippers located behind the ground shred the ground, and the rear mounted plant sows it.

At the end of the rut and when moving, the tractor’s hydraulic system is turned on, the lower linkage of the tractor’s hitch mechanism raises the front part of the chassis frame, the hydraulic cylinders 15 rotate the beam 8 relative to the frame 1, the wheels 9 roll back, raise the rear part of the frame and the beam 8. Simultaneously with lifting the beam 8 the plates 10 are rotated, raising the fasteners of the fastening of the lower rigs 11, which, resting with their ends into the bar 8, raise the spider to the transport position.

Thus, by means of one hydraulic drive, the working tools are mounted simultaneously to the transport position, mounted both on the frame and on the linkage mechanism.

When the guns are in the working position, the support wheels roll forward by means of hydraulic cylinders 15, the end parts of the lower longitudinal ribs no longer interact with the bar, as with a stop, and the splitter can freely copy the soil relief in the longitudinal vertical plane by turning the lower and upper longitudinal ribs relative to the fastening hinges. them respectively with plates 10 and chassis frame 1.

Subject invention

Chassis for compositing

agricultural units, containing a frame with a device for connecting it to a tractor, rolling support wheels, whose attachment brackets are hingedly connected to the chassis frame and connected to it by a hydraulic cylinder, the upper and lower longitudinal links of the tools mounted on the frame of the tool, characterized in that for the purpose of simultaneous lifting into the transport position of the tools mounted on the frame and attachment mechanism and ensuring the possibility of copying the relief of the soil in the working position of the tools mounted on the fur measurable hinge, cantilevers supporting wheels rigidly interconnected transversely positioned bolster with plates on which are hinged the lower longitudinal thrust adjusting mechanism, which rise to the transport position is provided by abutment of a surface of the timber.
