The garbage storage box 2 can be dumped (tilted) backward by extension (see FIG. 2). The dust box 3 can be rotated around a fulcrum P2 provided at the top, and can be opened and closed with respect to the dust container 2 by expansion and contraction of the swing cylinder 20 (see FIG. 3). The dust container 3 closes the opening 2a of the dust container 2 at the position shown in FIG. 1, and opens the opening 2a of the dust container 2 when rotated upward as shown in FIG. By dumping the dust storage box 2 rearward with the dust input box 3 pivoted upward, the dust in the dust storage box 2 can be discharged. Note that the dust input box 3 is normally fixed integrally to the dust container 2 by a tailgate lock (not shown), and the tailgate lock is a dust container that is stored by dumping the dust container 2. The trash is thrown out at the time of discharging or inspecting and servicing, so that the dust box 3 can be rotated.

  Next, a loading device T including a rotating plate 4, a pushing plate 5, a push cylinder 6, and a hydraulic motor Mo is provided in the dust box 3. The rotating plate 4 is provided so that both ends thereof are integral with the lower support shaft PL that is rotatably supported through the left and right side walls 3c of the dust box 3 via bearings and can be rotated about the axis. The pushing plate 5 is provided so that both ends thereof are integral with the upper support shaft PU, which is rotatably supported by the left and right side walls 3c of the dust box 3 via bearings, and can swing back and forth about the axis. . By rotating the rotating plate 4 clockwise, the dust thrown into the dust throwing box 3 can be scraped up from the bottom of the dust throwing box 3 to the upper front, and by swinging the pushing plate 5, the rotating plate The dust scraped up by 4 can be pushed into the front side (in the dust container 2). The upper and lower support shafts PU and PL extend in parallel to each other across the dust box 3.

  In one side wall 3c of the dust box 3, a hydraulic motor Mo is provided which is linked to the outer end of the lower support shaft PL and can drive the support shaft PL (and hence the rotating plate 4) in the forward and reverse directions. Further, the dust throwing box 3 accommodates a push cylinder 6 that is interposed between the dust throwing box 3 and the base end portion of the pushing plate 5 and can drive the pushing plate 5 back and forth.

  The rotating plate 4 and the pushing plate 5 can execute a predetermined dust loading cycle for forcibly pushing the dust thrown into the dust throwing box 3 into the dust container 2 in cooperation with each other. In this cycle, when there is a predetermined start operation input, the rotating plate 4 and the pushing plate 5 start from a state where the rotating plate 4 and the pushing plate 5 are in their initial positions (positions indicated by solid lines in FIG. 1). It ends when it returns to the initial position and stops.

  When the rotating plate 4 and the pushing plate 5 are stopped at the initial position, the push cylinder 6 is in the extended state, the hydraulic motor Mo is in the stopped state, and the corresponding electromagnetic valves are in the neutral position. When the solenoid 24s is excited, the push cylinder 6 contracts to swing the push plate 5 counterclockwise (return process), and when the solenoid 24e of the push cylinder solenoid valve is excited, the push cylinder 6 extends. As a result, the pushing plate 5 swings clockwise (pushing process). On the other hand, when the solenoid 25e of the solenoid valve for the hydraulic motor is excited, the rotating plate 4 rotates clockwise (forward rotation process), and when the solenoid 25s is excited, the rotating plate 4 rotates counterclockwise (reverse rotation process).

  When the dust container 2 is in the landing position (posture in FIG. 1), the dump cylinder 19 is in the most contracted state, and the dump cylinder solenoid valve is in the neutral position. When the solenoid 26e of the dump cylinder solenoid valve is energized, the dump cylinder 19 extends and dumps the dust storage box 2. When the solenoid 26s is energized, the dump cylinder 19 contracts to lower the dumped garbage storage box 2 to the landing position (dump lowering). When excitation is off and the dump cylinder solenoid valve is in the neutral position, both ports of the dump cylinder 19 are sealed.

  When the dust box 3 is closed (posture in FIG. 1), the swing cylinder 20 is in the most contracted state, and the swing cylinder solenoid valve is in the neutral position. When the solenoid 27e of the swing cylinder solenoid valve is excited, the tailgate lock operates in the unlocking direction, the swing cylinder 20 extends, and the dust throwing box 3 rotates upward. When the solenoid 27e is demagnetized and the solenoid 27s is energized, the hydraulic oil in the swing cylinder 20 is returned to the tank 21 via the swing cylinder solenoid valve due to the dead weight of the dust throwing box 3, whereby the swing cylinder 20 is contracted, and the dust box 3 is rotated downward. When the solenoid 28 of the tailgate locking solenoid valve is energized after the dust input box 3 reaches the downward rotation end, the tailgate lock is locked and the dust input box 3 is locked.

Therefore, the space for arranging the drive device 58 is reduced, or two types in the vehicle vertical direction are arranged. In the case where the horizontal beams are arranged, it is necessary to avoid the interference with the device disposed in the space Sd under the box by reducing the volume of the dust storage box 2 disposed above the horizontal beam. Therefore, a plurality of devices can be arranged in the space under the box without reducing the space for arranging the driving device or the volume of the dust container box 2.

  Further, the battery 46 (drive device 58) is supported on the upper portion of the rear mounting frame 72b, which is a cross beam, via the support frame 46b, and the dump cylinder 19 (load box tilting device) is supported on the lower portion by the cylinder bracket 80. Since the fixing portion of the support frame 46b and the hinge pin 80a do not interfere with each other, the driving device 58 and the dump cylinder 19 can be easily arranged on a single cross beam. As shown in FIG. 7, the support frame 46b is arranged on the vehicle front side of the mounting frame 72b, and the hinge pin 80a of the cylinder bracket 80 is arranged on the vehicle rear side, so that the support frame 46b and the hinge pin 80a Interference can be avoided.

  The present invention is not limited to the above embodiment.

The dump cylinder 19 is pivotally supported on the mounting frame 72b and the main girder 2c as the packing box tilting device to dump the dust storage box 2, but the dust storage box 2 is dumped using a link mechanism. May be. At this time, one end of the link mechanism may be pivotally supported on the mounting frame 72b.
In addition, the front support portion 63 and the rear support portion 64 are configured as separate members, respectively, and a concave portion is formed on the upper side while integrally forming them, and a part or all of the driving device 58 is disposed in the concave portion. It is also possible.
Moreover, although the hollow part 66 is formed of the main girder 2c, the front support part 63, and the rear support part 64, it can also be formed only by the main girder 2c formed bulky. In this case, a part of the main girder 2c is cut out to form a hollow part 66, and the box lower space Sd may be formed by the hollow part 66 and the vehicle body frame 1b.

  The box lower space Sd is formed below the lower surface of the main girder 2c, but outside or inside the main girder 2c in the vehicle width direction, above the lower surface, and from the bottom plate 2b of the dust container box 2. The lower space may be a box lower space Sd.

The drive device 58 disposed in the box lower space Sd is attached to the box lower mounting portion 72 before the dust container 2 is mounted on the support member 61, but is attached after the dust container box 2 is mounted. You may be made to do.
Further, the drive devices 58 arranged in the box lower space Sd and the box front space Sf are attached to the vehicle body frame 1b via the box lower attachment portion 72 and the box front attachment portion 73, respectively. Of these, the drive device 58 disposed in one or both of the spaces may be directly attached to the upper surface of the vehicle body frame 1b.

Moreover, although the valve block 33 is being fixed to the dust container 2 side, you may be fixing to the vehicle body frame 1b side. In this case, if the valve block 33 is connected to each of the cylinders 6, 19, 20 and the hydraulic motor Mo by using a flexible hydraulic hose instead of the hydraulic pipe 40, the connection described above when the dust container 2 is tilted. The state can be maintained.
Further, the drive device 58 operates all the cylinders and the hydraulic motor constituting the loading device T, but it is sufficient that at least one cylinder is operated.
In addition, the loading device T is a rotary plate type in which dust is loaded by cooperation of the push plate and the rotary plate, but may be a press type in which dust is loaded by a cycle motion of only the push plate 8. In this case, the pushing plate and the cylinder for operating the pushing plate constitute a part of the loading device T.
