が上がって不安定になる。(C) Problems to be solved by the invention With such a configuration, the rod of the hydraulic cylinder rotates with respect to the cylinder when the dump truck is turned, which adversely affects the seal ring of the piston. ， The resistance makes the rotation heavy. On the other hand, Japanese Utility Model Laid-Open No. 51-11509 discloses that a turntable is mounted on a frame and a dump carrier is installed on the turntable. The height of the table increases, and the center of gravity rises and becomes unstable.

ものである。(D) Means for Solving the Problems In order to solve the above problems, the present invention has a swivel dump carrier on which a tiltable and horizontally rotatable dump carrier is installed. In a carrier, a support shaft for supporting a dump truck is rotatably supported in a state of penetrating perpendicularly to the frame, and the dump truck is tiltably mounted by a horizontal pin on the support shaft that is viewed above the frame. The present invention provides a carrier having a swivel dump carrier, characterized in that a hydraulic cylinder is provided between a support shaft that is viewed below and a bottom surface of the dump carrier.

心位置はむやみに高くならない。(E) Action As a result, the hydraulic cylinder itself also turns with the turning of the dump truck, so that the cylinder and rod do not rotate relative to each other. In addition, since there is no such thing as a turntable between the frame and the dump bed, the position of the center of gravity does not unnecessarily increase.

等の適宜ロック手段15が設けられる。As shown in FIGS. 1 and 2, a frame 2 having an E-shape in plan view with a boss 3 attached is provided at the center of the loading platform 1, and rear wheels 4 are mounted on both left and right sides of the frame 2 and will be described later. A support shaft 5 that supports the dump truck is rotatably supported so as to vertically penetrate the boss 3. A hanging piece 7 fixed to the approximate center of the bottom surface of a box-shaped dump carrier 6 is axially attached by a horizontal pin 8 to a portion of the support shaft 5 that is viewed above the frame 2, and the dump carrier 6 is attached.
Is configured to be tiltable in a direction perpendicular to the axis of the horizontal pin 8 (in this case, the supporting point of the horizontal pin 8 becomes rearward as the mounting position of the hanging piece 7 becomes rearward, and as a result, Since the center of gravity is at the front, the tilting angle of the dump truck 6 can be increased). Then, the bottom surface of the dump carrier 6 behind the hanging piece 7 and the support shaft 5 that is viewed below the frame 2
A hydraulic cylinder 9 which can be expanded and contracted is provided in parallel with the tilting surface of the dump truck 6. Further, a swivel device 10 for swiveling the dump carrier 6 together with the support shaft 5, the hydraulic cylinder 9 and the like is incorporated between the dump carrier 6 and the frame 2.
As the swivel device 10, for example, an endless wire 13 is stretched between a passive pulley 11 fixed to a support shaft 5 and a drive pulley 12 pivotally supported in front of a connecting member 17, which will be described later. A handle 14 may be attached, a rack and pinion, a hydraulic cylinder, etc., although not shown. Further, a means for locking the swing of the dump truck 6 by the swing device 10, for example, an upper end portion of a lock pin 15 which can be vertically moved from the connecting member 17 side by a manual operation is provided in an appropriate number on the drive pulley 12 at a corresponding position. An appropriate locking means 15 for selectively engaging and locking the engaging holes 15b ... Is provided.

取り操向はこの方式によって行われる。If the balance weight 36 is attached to the lower front portion of the dump truck 6, the tilting angle of the dump truck 6 can be made larger, which has the advantage that the dumping work of the load can be made more efficient. You can also improve the fall prevention effect. Next, there is a control section 16 in front of the dump truck platform 1, and the coupling of the both 1, 16 is performed by a coupling member 17 extending forward from the frame 2 and a coupling member 18 extending backward from a mission case 28 described later. This is done by fitting a U-shaped member formed at the tip and a fitting member that fits inwardly in a superposed manner, and inserting the connecting pin 19 in the vertical direction into the superposed portion. Therefore, both the control section 16 and the platform section 1 are rotatable about the connecting pin 19 in the horizontal plane, thereby reducing the turning radius. The control unit 16 is equipped with a handle 20, a seat 21, an engine 22 and the like. Of these, the handle 20
Is connected by a connecting rod 26 from a steering mechanism 24 including a pitman arm 23 and the like to an arm 25 mounted on the side of the loading platform 1. This allows the handle
When 20 is turned, the above-mentioned members are actuated, and the control section 16 and the bed section 1 can be bent around the connecting pin 19. engine
The power of 22 is transmitted to a mission case 28, which is freely rotatably supported around the support shaft 27 in the front-rear direction, and is further transmitted to an axle 30 of a front wheel 29 of the control section 16. . At the center of the axle 30, a differential gear is housed and installed in a differential gear case 31 (hereinafter referred to as a differential case 31), so that steering is performed by this method.

The drive shafts (Fig. 3) and 42 are not only bendable via joints 40, 41, but also the center side end of which is fitted inside and outside by spline fitting etc.
The horizontal stoppers 43 are guides fixed in place on the frame 2 side to secure the rotation of the horizontal rotation plate 35 in the horizontal plane.

The dump truck 6 in the normal posture described above is retracted by operating the telescopic operation lever 32 to incline and retract the hydraulic cylinder 9, and the load is unloaded behind the carrier, or the lock means 15 is appropriately released. After the manual handle
By 14, the dump truck 6 can be turned to the desired left or right direction (it can be rotated within 90 degrees to the left and 90 degrees to the right when compared to the normal posture. This is called a 3-point dump) and it is locked again. Then, when the hydraulic cylinder 9 is also expanded and contracted at the locked position, the dump carrier 6 tilts around the horizontal pin 8 and the load can be unloaded at that position. Then, after the hydraulic cylinder 9 is expanded and contracted to return the dump carrier 6 to the horizontal state, it is returned to the normal posture in the same manner as the swing lock operation described above, and the next loading / unloading operation is started.

位置に設置できる。(G) Effect of the Invention As described above, according to the present invention, since the dump truck can be swiveled in the horizontal plane, so-called three-point dump is possible. In this case, the dump truck is mounted on the frame. The hydraulic cylinder for tilting, which is supported by a rotatable support shaft that is projected, is mounted between the support shaft and the dump truck, so the entire hydraulic cylinder rotates when turning, and the cylinder and rod Does not rotate relative to each other. Further, since it is not necessary to provide a turntable, a rotation guide mechanism or the like between the frame and the dump truck, the structure is simple and the dump truck can be installed at a low position with good stability.
