By the horizontal coupling piece 350 formed with a plurality of variable through holes 351 to the fixed through hole 321 is coupled to each other by a bolt (B), the PTO (P) and the work machine (W) of the tractor (T) ) Is configured to transmit power even when the drive shaft is twisted at an angle.

The bracket 362 of the joint shaft housing 360 having the male ply 361 is inserted between the horizontal coupling pieces 350 so as to be coupled to the bolt (B).

An extension joint shaft 370 may be coupled to the male spline 361 of the joint shaft fixing part 300, and the extension joint shaft 370 is formed inside the tapered drive guide shaft 371. Drive arm spline 372 is coupled to the male spline 361, driven guide shaft 374 having a driven arm spline 375 in the polygonal arm spline 373 formed into the drive guide shaft 371 A polygonal male spline 376 coupled to the is configured to be coupled.

Compression coil spring 377 is fitted to the polygonal spline 376 exposed between the drive guide shaft 371 and the driven guide shaft 374 so that a certain amount of play can be absorbed by the compression coil spring 377. have. That is, as the clearance with the drive shaft of the work machine W can be made variable, it is possible to prevent partial deformation or damage due to impact or overload.

The process of binding the work machine (W) to the tractor (T) using the tractor binding hole (200) having such a configuration is as follows.

First, the top link (T-1) provided at the rear of the tractor (T-1) is inserted between the coupling pieces 122 provided on the top of the work machine binding frame 110 is inserted into the fixing hole in the through-hole 121 Insert it so that it is fixed.

Next, the link coupling shaft 131c provided at the binding shaft unlocking unit 130 is coupled to the lower link T-2 provided at the rear of the tractor T, so that the tractor is located at the rear of the tractor T. The binding sphere 100 is to be coupled.

Next, the tractor binding upper frame 210 constituting the tractor binding port 200 and the worker binding lower frame 250 are coupled to the working tool front connection part W 'provided at the front of the working machine W. At this time, the other side of the adjusting piece 260 to the extension piece 211 of the tractor binding upper frame 210 to be coupled to the bolt (B), and then one side of the extension piece 211 is the work machine front connection (W '). To be coupled to the bolt (B). At this time, since the long hole 262 is formed in the adjusting piece 260 in the process that the adjusting piece 260 is coupled, it can be easily coupled.

Next, by loosening the U bolt (243) to the work machine binding lower frame 250 by the bolt through the work machine fixing bolt hole (243b) formed in the variable piece (243) in the state that the butt piece (241) is movable left and right. After the working machine W is coupled, the variable piece 243 is moved up and down to match the through bolt hole 243a formed in the variable piece 243 and the height adjusting hole 242a formed in the fixed piece 242. By fastening with a bolt, the tractor binding port 200 is coupled to the work machine (W).

Through the above process, the coupling process of the tractor (T) and the working machine (W) in the state in which the working machine binding sphere 100 and the tractor binding sphere 200 are coupled as follows.

First, the work machine binding hole provided in front of the work machine W in a state in which the top link T-1 provided at the rear of the tractor T is moved downward by driving the hydraulic cylinder not shown in the forward direction ( After the locking shaft 220 of the 200 is hooked to the tip of the hook piece 124, the hydraulic cylinder is driven in the reverse direction again so that the top link T-1 moves upward and the hook piece hooked to the tip ( 124 is moved along the inclined surface is to be seated in the hook groove (123).

Next, when the hydraulic cylinder is further moved while the hook piece 124 is seated in the hook groove 123, the binding shaft 230 is closed at the inlet of the binding shaft insertion groove 131a of the binding shaft fixing plate 131. As shown in Fig. 6A, the hook type member 132a is pushed upward and the spring 133 is compressed and the annular hook member 132a is rotated clockwise about the hinge axis 131b. When the inlet side of the binding shaft insertion groove 131a is opened, the binding shaft 230 is inserted.

Next, as the binding shaft 230 is inserted and the spring 133 is closed by the restoring force, the annular hook member 132a is rotated counterclockwise to be closed at the inlet side of the open coupling shaft insertion groove 131a. As the binding shaft 230 is prevented from being separated in the reverse direction, the work machine W is coupled to the tractor T.

Thereafter, after the necessary work is completed, the tractor T and the work machine W are separated by pressing the handle 135 clockwise and at the same time by reverse operation.
