In the case of a configuration in which the grain hopper is integrally assembled and supported on the rigid frame formed, the grain container frame is used as a base for mounting on the truck bed. , The rear end of the base is supported so that it can be rotated backward, and a post with a winch is installed upright on the front end of the base. It is carried out by winding the grain container with the frame backwards by the operation of the winch by wrapping it around the pulley on the bottom of the front end of the frame via the pulley installed on the upper end of the frame.

In the case where the grain container is configured by suspending the grain bag on the frame assembled in a cage shape, as shown in FIG. 1, the grain container is mounted on the loading platform 1 of the truck T. A frame f assembled in a cage shape is mounted and supported on the upper surface of an underframe-shaped base B to be tilted rearward about a fulcrum shaft f ′ provided on the rear end side. A grain container G is configured by suspending a grain bag g having an openable / closable inlet on the upper surface side and a freely openable / closable discharge cylinder portion on the rear side at f. Then, on the front end side of the base B, a support column c standing upright along the front surface of the frame f is erected, and the winding drum is rotated by the rotation of the handle d to wind the cable b therein. The winch a that operates as described above is assembled, and a pulley w for fixing the position that guides the cable b fed from the winding drum of the winch a is supported on the upper end of the column c, and the rotation of the winding drum is performed. A movable pulley y that moves up and down by a cable b that is fed or wound by is pivotally supported at the lower end on the front surface side of the frame f, so that the dump container is rotated by a manual operation of the winch a. I have to.

[Problems to be solved by the device]

 The above-mentioned conventional means pulls up the movable pulley y pivotally supported on the lower end on the front surface side of the frame f by the operation of the winch a, and when the frame f is tilted and turned rearward, the movable pulley y is moved. As shown in FIG. 2, the axial support position of the pulley y moves rearward as the pulley y rises, and becomes separated rearward with respect to the column c. Since the cable b between the w and the pulley y at the lower end of the frame f is stretched obliquely, a backward bending load is applied to the support column c, so that the support column c can withstand this bending load. It has to be made to be durable, and there is the problem of making it difficult.

This problem is that when the pillar c is provided so as to be tiltable back and forth with respect to the base B and the winch a is operated to pull up the movable pulley y, the pulley y is moved backward. The column c is tilted rearward by the amount of movement of the column c, and the cable b between the pulley w at the upper end of the column c and the pulley y at the lower end of the frame f is held in parallel with the rear surface of the column c. The problem can be solved by adopting a means for applying only the load in the longitudinal direction to the column c.

However, in this case, the column c for mounting and supporting the winch a freely rotates back and forth, which causes a problem that the winch a is not stable and its operation becomes difficult. Further, from this fact, when the handle d is pivotally supported on the base B, a bendable universal joint shaft must be conducted between the handle d and the drive shaft of the winch a, which makes the mechanism troublesome. The problem comes out.

[0007]

【Purpose】

 The present invention has been made in order to solve these problems in the conventional means, and in a dump device for tilting and rotating a grain container by a winch, a fixed pulley for guiding a cable of the winch is used. The strut supported on the upper end side can be constructed as a simple structure by applying only the load in the direction along the longitudinal direction of the strut, while the manual operation of the winch can be performed stably and accurately. The aim is to provide new means of
