    A coupling device for connecting the power take off means of an agricultural tractor to a driven shaft of an implement includes an upper guide member 20 connected between the tractor and the implement from which the drive shaft 16 is resiliently supported by the springs 42. The guide member 20 is telescopic and is lockable, when the tractor is coupled to the implement, by means of a lever arm 40 to which the springs 42 are connected. In the coupled condition the lever arm is retracted thereby releasing the drive shaft 16 from the resilient bias of the springs 42 and thereby releasing the drive shaft bearings from any spring loading during operation.

    figure 1
    This invention relates to a hinged attachment for attaching a gun to a tractor,
    The purpose of the invention is to increase the adhesion reliability.
    FIG. Figure 1 shows the hitch in the clutch process; in fig. 2 - the same, after coupling; in fig. 3-6 - top dyshlo, a section; in fig. 7 and 8 - clutch frame of the gun and the tractor.
    FIG. 1 shows the front part of the tractor 1 with a power take-off shaft 2 for a rotating drive of front mounted implements. The guns are lifted by means of a frame hitch consisting of a coupling triangle 3 on tractor 1 and a coupling triangle 4 on an implement 5 (and for coupling, the coupling triangle 3 located on a tractor enters the coupling triangle 4 located on the implement. The coupling on the tractor the triangle 3 is connected to the tractor through the two lower drawbars 6 and the upper drawbar 7. When the clutch is attached, the upper drawbar 7, which is made with the possibility of changing the length, is released from its fixed working position by the control lever 8, which can be done from the cab The traction line through the traction cable 9 and the pressure spring 10 installed inside the drawbar and acting along its axis expand the upper drawbar to the maximum length of the working tool 5, and the propeller shaft part 11 is held in the engaged position with the help of an elastically formed plug. The shaft connected to the tractor is connected via a spring 13 to the control lever, while the part 12 of the drive shaft connected to the tractor is located coaxially with the part 11 of the drive shaft connected to the working tool 5.
    To attach the gun, the tractor is brought to the gun and the tractor triangle 3 is inserted into the tractor triangle 4 guns by raising the lower drawbars 6. The shaft 11 of the propeller shaft connected to the gun is simultaneously inserted into the shaft 12 connected to the tractor. The connection of both parts of the cardan shaft for the transmission of torque is carried out using shaped pipes.
    With further supply of the tractor 1 to the working tool 5, the upper drawbar is moved back so that it is spring-loaded, connected by means of springs 14 with a lever
    The 8 controls of the latch 15 can fall into the lock-and-lock, bikes 16. At the same time, the control lever 8 is deflected around the axis 17 of the lever 8 to the axis of the upper drawbar 7, as a result of which the tension spring or springs 13, which hold the cardan shaft 12 with the tractor, are unloaded.
    Thus, the bearings needed between the torque-transmitting shaped pipes and the protective
    pipes 18 and 19, provided as protection against contact, release the spring from tension.
    An intermediate element 21 or a link, for example a chain, may be provided between the spring 13 and the point of attachment 20 to the lever 8 (FIG. 2). The element has a certain length relative to the spring 13 and a distance a between the point 20 of attachment of the spring to the lever 8 and the axis 17.

    Invention Formula
    The attachment of the working tool to the tractor, which contains the coupling device of the working tool and the tractor, the self-locking drive shaft, consisting of two
    parts, one part of which is connected to the tractor, and the other part to the working tool, and a pivot shaft control lever, rotatable in the longitudinal-vertical plane, connected to the coupling device, which is due to the fact that the coupling device made in the form of two lower and one upper dyshl, while the control lever is pivotally mounted on the upper dyshl,
    provided with a flexible rod attached to the free end of the lever, and connected to the part of the drive shaft connected to the tractor with a spring and / or intermediate element, the length of which is longer than the distance between the spring attachment point on the part of the drive shaft and the spring attachment point and or an intermediate element on the control lever, which is located between the hinge of fastening
    the lever to the upper drawbar and the junction of the control lever with the thrust.
