Description of the Related Art In order to improve the annual operation rate of a working vehicle, it is preferable that a snow removing machine or the like can be mounted in addition to a general-purpose working device such as a bucket or a hydraulic shovel. For this reason, a quick coupler (or a quick hitch) which is attached to the tip of the work vehicle arm and can be operated from the work vehicle side is used. In the conventional quick coupler, it is necessary to remodel the attachment on the working device side so as to correspond to the coupling operation mechanism of the coupler, and there is a disadvantage that the remodeling requires cost and labor.

A link device is formed by connecting a pin 37 to one end of a link 38 connected to a pin 39. Pins 40 and 42 project from the inner surfaces of the open jaws 24a and 25a on both sides, and these pins penetrate windows or slots 41 and 43 provided on the inner wall of the support frame, respectively. In addition, the central jaw 2
Pins 44, 46 penetrating through the elongated holes 45, 47 of the support frame wall are symmetrically protruded from both side surfaces of 3a. Interlocking device E
1 and E2 have the same configuration. The interlocking device may be a single connecting rod as long as each end is fitted and connected to the pin 42 and the pin 46, but a length adjusting means 50 capable of resisting pushing and pulling corresponding to the height adjustment of the support frame. , 51 are preferred. The pin receiving recesses C1 and C2 of each clamp device are shown in FIG.
As shown in FIG. 9, the side surface is formed in an intaglio shape, and the inner surface of the intermediate portion of each jaw is tapered as shown in FIG.

The pins 13, 18, and 19 for connecting the coupler of the present invention and the work vehicle arm also have the same specifications. A pair of hydraulic cylinders 3 in the coupler of the present invention
0 is connected in parallel and operated from the working vehicle side, and when the rods 33 of both cylinders are retracted (moved upward in the figure), the rotating body 35 is rotated, and the both-side open jaws 24 are
a and 25a are opened. Since the central opening jaw 23a is connected to both opening jaws via the interlocking device, the center opening jaw 23a opens by the same angle in conjunction with this opening movement. In this state, each clamp device is matched with each pin position of the working device, each pin is fitted into the pin receiving recess of the fixed jaw, and then the hydraulic cylinder is operated to lower the piston rod 33, whereby each open jaw is closed. Clamp each pin. At this time, a stopper 35a for setting the position of the pin shaft 37 of the rotating body 35 connected to the piston rod to a position slightly exceeding the center line of the connecting shaft 39 and the connecting pin 39 of the opening jaw (a so-called over-center type) is provided. By providing this, even if the cylinder oil pressure fluctuates during the operation, the clamping force of the open jaw does not become unstable, so that it is safe.
Further, the movement of each of the left and right cylinders is ensured to be interlocked via the central opening jaw 23a and the left and right interlocking devices.

外力に対して安定である。[Effect] The coupler of the present invention is extremely economical as compared with the conventional coupler because the existing pins can be used without modifying the working device, and is used in combination with the pin position correspondence function to various devices. It is also possible to use a working device that has not been used, and it is possible to increase the annual operating rate of the working vehicle. Further, unlike the conventional coupler, which is in contact with the semicircular arc of the pin or the inner peripheral surface of the hook, unlike the conventional coupler, the clamp device grips the entire circumference of the pin and is therefore stable against external force from the working device side. .
