The invention relates to the field of agriculture, in particular to combined machines.

Known combined tillage machine containing three-section along the length of the frame and fixed thereto, the working bodies of the USSR No. 604527, MKI7A01B 59/04). To improve longitudinal stability and decreasing dimension in height frame made in sections pivotally interconnected and further conjugated by means of hydraulic cylinders which lift the sections and the translation machine in transport position.

A disadvantage of the known construction is that each of the hinged connection of the sections required in the hydraulic cylinder, and providing a working position of the sections requires rigid fixation manually, which is connected with the tractor from the tractor cab.

The closest to the technical nature of the claimed is selected as a prototype combined tillage machine, comprising a series arrangement pivotally connected and further connected by a cylinder frame sections with disc and ripping the working bodies and the roller (Pat. OF THE RUSSIAN FEDERATION NO. 2483508, A01B 59/04). In transport position the frame on the side view has a Z-shape. When shifting from transport to working position, a second frame section (Ripper working bodies),turning is lowered, the angle between it and the third frame section with the roller increases, but even rink in contact with the soil remains less than 90°. Therefore, when lowering the car rink, usually not rolled back, and he rolled forward and prevents the penetration of the working bodies, placed in front of him. This shortcoming makes it difficult to use the machine.

An object of the invention is to provide a reliable translation machine from the transport position into the working position.

The technical problem is solved in that the curtain combined machine containing a consistent set pivotally coupled three sections of the frame with the working bodies, such as disk and ripping on the front and second sections, and rollers mounted on the lower end of the third section of the frame, the front and second sections are connected by a hydraulic cylinder to rotate the second section on the fingers of her pivotally mates with the first section, according to the invention the front and the third sections of the frame are connected by a rod pivotally coupled with the fingers mounted on these sections, on the front section, the axis of the finger to pull on the front and above the axis of the finger pivotally connecting the first and second sections of the frame, the finger swivel thrust to the third section of the frame is located at its upper end in front of the axis of the pin�connection of the second and third frame sections and, at least one finger to install traction is made rotatable about its axis, in addition, when the transport position of the machine the distance between the most distant points of the fingers to install the thrust is less than its operating length, and rink in contact with the soil, this distance is equal to the working length of pull, and the angle between the second and third frame sections, at least not less than 90°. In addition, the working length of pull is made adjustable.

The invention is illustrated by drawings. Fig.1 shows a hinged combined machine in transport position, side view; Fig.2 - the same, before penetration of the working bodies rink in contact with the soil, side view. Fig.3 shows the position of the frame of the rink at the time of his contact with the soil in the absence of thrust between the first and third sections, side view.

Hinged combined machine contains three consecutively placed pivotally coupled to the frame section. On the front section 1 with a hinge device 2 and jaws 3, 4 contains the open and closed grooves 5, installed the disc operating 6. In the second section of the frame 7 is fixed shank working bodies 8 and the connecting fingers 9 disposed in the front of the frame and installed in open grooves 4, and the fingers 10 is in closed grooves 5. The rear part of the section 7 contains the cheeks 11 of the fingers 12, which are installed tert�I section 13 of the frame. At its lower end is fixed boronka 14 and an ice rink 15. Front 1 and the second section of the frame 7 are further connected by a hydraulic cylinder 16 which, when the transport folding machine turns up the second section 7 of the 10 fingers her swivel front section 1.

Front 1 and the third section 13 of the frame connected by rods 17 pivotally mounted on both sides of the section 7 of the frame on the fingers 18 placed on the cheeks 3 1 front section of the frame and rotating about its axis, the fingers 19 on the upper ends of the third section 13. Rod 17 contains the eyelet for mounting on the finger 18 and the pivot pin 19 has a transverse hole for the mounting of traction 17. The axis of the finger 18 is placed in front of and above the axis of the finger 10. Pivot pin 19 is located in front of the axis of the finger 12 swivel 7 second and third frame sections 13.

In the transport position of the machine the distance l between the most distant points of the fingers 18 and 19 is less than the working length 5 thrust, and when shifting from transport to working position and the contact of the rink 15 with the soil, the distance l is equal to the working length of s rods 17, and the angle β between the second 7 and third frame sections 13 is at least not less than 90°.

The working length of s thrust 17 consider the distance from the point of eyelets closest to the front end 17 to thrust element (nut) limiting the movement of the thrust rotation�now one of the finger 19. Working length s thrust 17 is made adjustable by means of nuts on the end of it. Length adjustment of traction 17 when changing roll diameter 15 or shank type bodies 8.

In the second section of the frame 7 can be installed (with a chisel) support wheel 20 with screw adjustment mechanisms for depth, brackets 21 limiting the turning down of section 13 of the frame and lowering the rink 15-transportation of the machine, and adjusting bolts 22 that limits the turn-up section 13 of the frame and the depth of the machine when it is working without wheels.

The device operates as follows.

When shifting from operating position to transport position her maglubiyet by means of a hinged device of a tractor, then a hydraulic cylinder 16 is moved forward second section of the frame 7 with 10 fingers until it stops in front of the rib grooves 5 and the release of the fingers 9 from open grooves 4, then section 7, turning on the fingers 8, together with section 13 of the frame will rise up into the transport position. While turning the fingers 19 are some down thrust) 17, the thrust is rotated by the finger 18 and the frame 13 with the roller 15 is rotated by the fingers 12 and is lowered until it stops in the brackets 21. In the transport position of the machine the distance l between the most distant points of the fingers 18 and 19 is less than the working length s of thrust.

When shifting from �transport position into the working position by a hydraulic cylinder 16 is rotated section 7 of the frame and lower the car to the supporting surface. The finger 9 comes into the open groove 4, and a hydraulic cylinder 16 moves backward second section of the frame 7. Since the thrust axis of rotation 17 (the axis of the finger 18) placed in front of and above the axis of the finger 10, when approaching the rink 15 to the supporting surface of the rod 17, by acting on the pivot pin 19, section 13 rotates the frame and deflects it back from the vertical position. While working length thrust s=l, and the angle between frames 7 and 13 is at least 90°. Upon further lowering of the machine rink 15 on the support surface (soil) would move backwards, preventing the penetration of the working bodies mounted on front 1 and second frame sections 7.

When the machine is a hydraulic cylinder 16 is set to "neutral". Under the action of traction resistance section 7 of the frame remains in the backwards position, additional fixation is required.

The use of this device allows to provide reliable shifting from transport to working position.
