Description

The subject of the invention is a equestrian multitool, consisting of a frame with a set of different working elements, pivotally connected to the main frame, supported on two running wheels and equipped with a shaft fitting. The working frame is rotated in the horizontal plane to direct the working bodies between the rows between the arms, and the lever to the transport position, by the lever.

In such ku; 1tn1 ator. The hoist lifting mechanism adjusts the design of the cultivator and requires a remarkable reinforcement during its maintenance.

In the proposed cultivator, this disadvantage is eliminated by the fact that the function of the idle-lift lever is performed by the control knobs, by fixing the working frame in the transport position, by means of a mechanical mechanism consisting of a bracket with two grooves, into which the spring-loaded latch is inserted through the lever system from the handle. control the cultivator, with one notch serving to fix the working frame in irregular and volatile conditions when turning the cultivator, and the other to fix the frame in the transport position.

FIG. 1 is a view of a cultivator; c. FIG. 2 above and in FIG. The y and 4 mechanisms fix the transport position of the working frame in two projections.

The main frame 1 of the cultivator rests on the D1sh running train 2 and has a double girder 3. The working frame 6 is attached to the main frame with double hinges 4 and 5 and 5, which together with the frame 1 II of 5 g represents the hinge articulated in horizontal plane and alorallogram.

The frame 6 is attached to the working bodies 7, and if necessary, increase the width of the grip-dopoliptelp the working bodies 8; Frame 6 with handles 9.

No. 80299

The latch TpaiicjropTiioro position of frame 6 consists of a bracket 10 secured on the main frame, having two notches A and B. Through the bracket 10 freely passes the i-pivot shaft I, on which the hinges 12 are rigidly mounted and pivotally connected through 13 with 5 working legs 5 frame 6. On the lifting shaft, the lever 14, 1 is rigidly fixed. In which the latch 15 runs, irizhimaema down spring 16.

A hinge 17 is connected to the pivot lever 14, carrying a latch 15. Wire rod 18 extends from the end of the bar 17 to the control handles.

When the cultivator is operating, the thrusters 5, 13 and 12 and the lever 14 are also in the lowest position, and the irish 15 does not touch the crown of the Tain 10 (shown by the dotted line parafig. 3). The working rotation of the handle 9 (in the directions shown by the arrows in Fig. 2) directs the barrel organs along the aisles.

Perrd by turning the cultivator at the end of the pens working raise the handles 9 upwards, thereby raising the frame 6 with the working bodies. At the same time, ti 5 will shift upward ti 15 and tipper 12 rotates lift shaft 11, and with it the lever 14. When latch 15 reaches the notch A, it pushes the spring 16 into it and locks the working frame in this way in high idodeiiii.

For moving to another area, it is necessary to raise the frame even higher; A further raise of the handles causes the latch 15 to pop into the recesses B and fix this rise.

To lower the frame 6 into the working and working condition of the tractor 18, it pulls back the nlap 17 and thereby removes the latch 15 of the slot A or B. When this frame is due to its own weight, it is lowered to the ground.

Subject invention

Multi-cultivator, characterized in that the device for fixing the sub-frame with a set of working bodies is shaped as a base-mounted bracket with two external grooves into which the spring-loaded latch is inserted through the system of levers from the handle of the cultivator, and one dimple turns for fixing the working frame in a raised position when turning the cultivator, and the other for fixing the frame in the transport position.
