The hydraulic pressure switching unit 31 includes a plurality of electromagnetic valves (not shown), and the hydraulic oil discharged from the hydraulic pump 32 is supplied to a desired cylinder by switching the open / close ports of these electromagnetic valves. Thereby, switching of the expansion / contraction operation of each cylinder 14, 16, 21, 27, 28 is controlled, or the operation is stopped. An accumulator 29 is connected to a hydraulic pipe 30a for operating the discharge cylinder 21 via an electromagnetic valve 29a as a switching valve.

  In the electromagnetic valve 29a, the accumulator 29 is cut off from the hydraulic pipe 30a when the hydraulic circuit is operated. On the other hand, when the garbage collection vehicle 1 travels with an empty load, particularly when the discharge cylinder 21 is extended, the solenoid valve 29 a is switched so that the pressure oil of the accumulator 29 acts on the discharge cylinder 21. As a result, the hydraulic pressure in the discharge cylinder 21 is maintained and the discharge cylinder is prevented from being bent, so that the seal member at the tip of each stage of the discharge cylinder 21 is prevented from being damaged.

  The hydraulic circuit 30 includes a hydraulic tank 33 that stores hydraulic oil. The hydraulic circuit 30 is configured such that the hydraulic oil in the hydraulic tank 33 is sucked up by the hydraulic pump 32 and distributed to the supply-side hydraulic pipe 30 b and supplied to the hydraulic pressure switching unit 31. Then, the hydraulic oil that has passed through the hydraulic pressure switching unit 31 is circulated through the recovery-side hydraulic pipe 30 c, filtered by the return filter 34, then circulated through the hydraulic pipe 30 c ′, and recovered again in the hydraulic tank 33.

Or output a rising signal.

  In addition, when the reversal instruction button is pressed, the operation device 36 outputs a reversal signal for reversing the compression plate 15 to the controller 35. When the controller 35 receives various signals output from these operating devices 36, the controller 35 switches the opening / closing port of the solenoid valve in accordance with the various signals to the hydraulic pressure switching unit 31, thereby switching the sliding cylinder 14 and the swing cylinder 16. A control signal for controlling to extend or stop is output.

  Next, the operation of the dust loading device 8 having the above configuration will be described with reference to FIGS. FIG. 5 is a schematic longitudinal sectional view for explaining the lifting end position of the refuse loading device 8, FIG. 6 is a schematic longitudinal sectional view for explaining the inversion finishing position of the dust loading device 8, and FIG. FIG. 8 is a schematic longitudinal sectional view explaining the end position, and FIG. 8 is a schematic longitudinal sectional view explaining the compression end position of the dust loading device 8. 5 to 8, the sliding cylinder 14 is omitted for simplification.

  As shown in FIG. 5, in a state where both the sliding cylinder 14 and the swing cylinder 16 are extended and the sliding plate 10 is in the rising end position (the uppermost position), the dust 40 is put into the dust charging box 5 through the charging port 7. And push in the loading instruction button. When the loading instruction is made by the loading instruction button, the operation device 36 outputs the aforementioned loading signal to the controller 35. The controller 35 receives this loading signal and controls the operation of the hydraulic pressure switching unit 31 so as to perform the following loading operation.

  First, in the state shown in FIG. 5, the swing cylinder 16 is retracted and the compression plate 15 is reversely operated to reach the reverse end position (see FIG. 6) (reversing step). Thereafter, the sliding cylinder 14 is retracted and the sliding plate 10 is lowered, and the compression plate 15 is lowered accordingly (lowering step). When the compression plate 15 reaches the lowering end position (see FIG. 7), the swing cylinder 16 is extended to swing the compression plate 15 forward, and the process proceeds to the compression step.

  When the compression plate 15 swings to the compression end position (see FIG. 8) (compression stroke), the sliding cylinder 14 is extended to raise the compression plate 15 (ascending step). When the compression plate 15 reaches the rising end position (see FIG. 5), the series of loading operations is finished. As a result, the dust loading operation can be repeated with each process of inversion, lowering, compression, and ascending as one cycle.

  As described above, when starting to load the dust 40 into the dust container 3, the discharge cylinder 21 is extended and the discharge plate 17 is disposed at the rearmost position in the dust container 3. . And when the force with which the dust 40 loaded by the dust loading device 8 presses the discharge plate 17 reaches a predetermined value or more, the discharge cylinder 21 is retracted so that the discharge plate 17 gradually moves forward. I have to. By such a movement operation of the discharge plate 17, the dust 40 can be loaded into the dust container 3 while being compressed.

  When the dust container 3 is filled with the dust 40, the dust container 5 is tilted to open the rear opening 4 of the dust container 3 and extend the discharge cylinder 21, thereby expanding the dust container box. The discharge plate 17 located at the front part of 3 is moved backward so that the dust 40 accommodated in the dust storage box 3 can be discharged.

  Here, in the refuse collection vehicle 1 in the present embodiment, the number of stages of the discharge cylinder 21 is large and the total length is long, so that the deflection of the discharge cylinder 21 increases. Therefore, the seal member at each end of the discharge cylinder 21 may be damaged, and oil may ooze out from the seal member. The oozed oil is received by the oil receiving portion 25 provided below the step of the discharge cylinder 21. It is accepted. Therefore, in the refuse collection vehicle 1, the oil that has oozed out of the discharge cylinder 21 is prevented from dripping into the dust container 3.

Therefore, the oil that has oozed out due to the deflection of the multistage discharge cylinder 21 is transmitted to the lower stage through each stage of the discharge cylinder 21, and is received in a concentrated manner by the oil receiving portion 25 provided below the lowest stage. Can do. As a result, the collected oil can be managed collectively, and the collected oil can be easily treated.

  In addition, the garbage collection vehicle 1 has a guide portion including the guide groove member 19 and the guide convex member 20 and an oil supply pipe 26 that supplies oil from the oil receiving portion 25 to the guide portion. The discharged oil can be received by the oil receiving portion 25 and supplied to the guide portion by the oil supply pipe 26 and reused for lubrication between the guide groove member 19 and the guide convex member 20. Thereby, it is not necessary to discard the collected oil, and waste can be eliminated.

  In the garbage truck 1 in this embodiment, the solenoid valve 29a is normally switched so that the accumulator 29 is disconnected from the hydraulic pipe 30a of the discharge cylinder 21, but the waste 40 is not loaded and discharged. When the cylinder 21 is not operated, the electromagnetic valve 29 a is switched so that the accumulator 29 is connected to the hydraulic piping 30 a of the discharge cylinder 21. Thereby, when the discharge cylinder 21 is not operated, the hydraulic pressure in the discharge cylinder 21 can be maintained by the accumulator 29 and the deflection of the discharge cylinder 21 can be prevented, so that the tip seal member at each stage of the discharge cylinder 21 can be prevented from being damaged. Therefore, it is possible to prevent oil bleeding from the front end of each stage of the discharge cylinder 21.

  In the present embodiment, the oil receiving portion 25 is provided only below the step between the first piston tube 21b and the cylinder tube 21a of the discharge cylinder 21, but is provided below each step of the discharge cylinder 21. It is also possible. In this case, it is possible to connect the respective oil receiving portions by piping, collect them in the lowermost oil receiving portion 25, and perform the same processing as described above.
