Description

  The present invention relates to a garbage truck.

  A garbage collection vehicle has a cargo box mounted on the vehicle body, and a tailgate having a built-in dust loading device is connected to the rear of the cargo box. The dust loading device conveys the dust thrown into the tailgate into the packing box, the rotating plate that transports the dust thrown into the tailgate to the packing box side, and is carried by this rotating plate. Rotating plate type equipped with a pushing plate that pushes the dust into the packing box, a scratching plate that rotates and scrapes the dust put into the tailgate, and a pushing that lifts the dust together with the pushing plate and pushes it into the packing box A compression type equipped with a plate is well known.

  Also, as a discharge device that discharges dust from the packing box, a tilting type that discharges the dust in the packing box by lifting and tilting the front side of the packing box, and storing a discharging plate in the packing box, There are known a discharge plate type that retreats and discharges dust, and a combination type that accommodates the discharge plate in the packing box and tilts the packing box. The front wall of the packing box that houses the discharge plate is provided with an inspection hole that is used when checking the inside of the packing box in front of the discharge plate and when workers enter and leave for cleaning. The inspection hole is tightly closed so that the odor does not leak.

  As shown in FIG. 4, these dust loading and unloading devices are driven by hydraulic oil supplied from a hydraulic pump 20 driven by a part of the engine power of the dust collecting vehicle taken out by the PTO device. It was. In this way, when using a part of the engine power as the driving force for the dust loading device, etc., the engine is operated and the dust is loaded while the engine speed is increased to obtain the required output. ing.

  By the way, since a relatively large hydraulic pressure is required when operating the dust loading device, the engine output has been increased. However, in recent years, as a countermeasure against engine noise during loading, a cycle is required when loading dust. Various techniques have been proposed to increase the oil pressure without increasing the engine output by supplying electric power.

For example, an induction machine that generates electric power from engine power and a battery are provided, and a motor is driven by the electric power generated by the induction machine and the electric power supplied from the battery, and the hydraulic pump is operated by the motor. Therefore, a technique for driving the dust loading device has been proposed (see, for example, Patent Document 1). When such a technique is adopted, in addition to the electric power from the induction machine, the electric power from the battery can be supplementarily supplied to the motor, so that a large hydraulic pressure can be periodically generated when the garbage is loaded.
Japanese Patent Laid-Open No. 5-4702 (2nd page, FIG. 1)

  However, even in the technology described in Patent Document 1, since a part of the engine power is still used as the driving force of the dust loading device, the engine is not loaded when the dust is loaded even though the vehicle is not running. It is necessary to maintain the state in which the is operated. For this reason, even if the increase in engine output could be prevented, environmental problems due to the generation of noise and exhaust gas have not been solved.

  An object of the present invention is to provide a garbage collection vehicle capable of preventing generation of noise and exhaust gas by realizing "idling stop" at the time of dust loading and saving fuel for operating the engine. is there.

  In order to solve the above-described problems, the invention according to claim 1 is directed to a vehicle body having a cargo box mounted on the rear side of the cab, a tailgate continuously provided at a rear portion of the cargo box, and built in the tailgate. In a refuse collection vehicle comprising a refuse storage device and a storage battery for supplying electric power, the dust storage device is driven by power supplied from the storage battery.

  According to invention of Claim 1, a refuse loading apparatus can be driven with the electric power supplied from a storage battery. Accordingly, it is not necessary to use a part of the engine power as the driving force of the dust loading device as in the conventional dust loading device, so that an “idling stop” at the time of dust loading can be realized. As a result, it is possible to prevent noise and exhaust gas from being generated when dust is loaded, and to save fuel for operating the engine.

  According to a second aspect of the present invention, in the refuse collection vehicle according to the first aspect, the packing box is tilted so that the rear part of the packing box is positioned relatively downward with respect to the front part of the packing box. Further comprising tilting means and a storage box for storing the storage battery, wherein the storage box is disposed between the driver's cab and the packing box so as not to prevent tilting of the packing box. And being fixed to the vehicle body.

  According to the invention described in claim 2, since the tilting means for tilting the packing box is provided so that the rear part is positioned relatively downward with respect to the front part of the packing box, the garbage is disposed behind the packing box by the action of gravity. The storage box for storing the storage battery is located between the driver's cab and the packing box and does not prevent the packing box from tilting (for example, a position slightly separated from the packing box). ) And is fixed to the vehicle body, so that the storage battery does not receive an impact when the dust is discharged due to the tilting of the packing box. Further, since the storage battery does not tilt with the packing box, there is no fear of dropping due to tilting, and power can be supplied stably.

  The invention according to claim 3 is the refuse collection vehicle according to claim 1, further comprising an inspection hole provided in a front wall of the packing box, and a storage box for storing the storage battery. Is arranged between the cab and the cargo box and is movable in the left-right direction of the vehicle body, and the inspection hole is closed and opened by moving the storage box in the left-right direction of the vehicle body. And

  According to the third aspect of the present invention, for example, in a garbage collection vehicle in which the discharge plate is stored in the packing box, the storage box for storing the storage battery is disposed between the cab and the packing box, and the left and right direction of the vehicle body. Since the storage box is moved in the left-right direction of the vehicle body, the inspection hole of the packing box can be closed and opened. Therefore, the storage box can function as a lid member for the inspection hole. In addition, the storage box for storing the storage battery is movable in the left-right direction of the vehicle body, and the storage battery can be loaded by protruding the storage box from the vehicle body, so that the storage battery can be easily replaced.

  The invention according to claim 4 is the refuse collection vehicle according to claim 3, comprising a rail provided on the vehicle body along the left-right direction of the vehicle body, and a wheel provided at a lower portion of the storage box, The storage box moves in the left-right direction of the vehicle body as the wheels of the storage box travel along the rail of the vehicle body.

Further, fuel for operating the engine can be saved.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the present embodiment, a dust collection vehicle equipped with a “rotary plate type” dust loading device will be described as an example.

  First, the structure of the garbage truck 1 which concerns on this Embodiment is demonstrated using FIGS. 1-3.

  As shown in FIG. 1, the garbage collection vehicle 1 includes a vehicle body 4 on which a cab 2 is mounted at the front and a cargo box 3 at the rear, a tailgate 5 connected to the rear of the cargo box 3, A dust discharge plate 6 configured to be movable in the front-rear direction of the vehicle body 4 in the packing box 3 and pushing the dust in the packing box 3 backward to discharge, a dust loading device 7 built in the tail gate 5, and a storage battery for supplying power 8, a storage box 9 for storing the storage battery 8, an engine driven by a predetermined fuel, a PTO device for extracting engine power, a hydraulic pump driven by the power extracted by the PTO device, and driven by electric power supplied from the storage battery 8 The electric pump 10 (see FIG. 3 (a)) to be configured is provided. The engine, PTO device, and hydraulic pump are not shown.

  As shown in FIG. 1, the cargo box 3 is fixed to the vehicle body 4 in a state of being arranged at a predetermined interval from the cab 2. The front wall of the packing box 3 is provided with an inspection hole (not shown) used when cleaning the back surface of the dust discharge plate 6. The size and shape of the inspection hole can be appropriately determined in consideration of the specifications of the dust discharge plate 6, the maximum load of dust in the packing box 3, and the like. In the present embodiment, an inspection hole is provided in the left part of the front wall of the packing box 3.

  The tailgate 5 and the dust discharge plate 6 are driven by hydraulic oil supplied from a hydraulic pump driven by engine power extracted by the PTO device. That is, the tailgate 5 and the dust discharge plate 6 are driven while the engine is operating.

  As shown in FIG. 2, the dust loading device 7 rotates in a predetermined direction (in the direction of arrow A), so that the dust G thrown into the tailgate 5 is lifted and conveyed to the packing box 3 side. There is a rotating plate 7a, and a pushing plate 7b that pushes the dust G conveyed by the rotating plate 7a into the cargo box 3 by swinging in the longitudinal direction of the vehicle body (the direction of the arrow B and the arrow C). .

  As shown in FIG. 3A, the rotating plate 7 a and the pushing plate 7 b of the dust loading device 7 are driven by hydraulic oil supplied from an electric pump 10 driven by electric power from the storage battery 8. That is, the rotating plate 7a and the pushing plate 7b are driven by the electric power supplied from the storage battery 8 even when the engine is stopped.

  The storage battery 8 supplies power for driving the rotating plate 7a and the pushing plate 7b of the dust loading device 7. A plurality of storage batteries 8 are accommodated in the storage box 9 and are detachable, and can be replaced with spare storage batteries when the power is reduced. In the present embodiment, a storage battery 8 that can be charged by a household power source and can be charged from an in-vehicle state is employed.

  As shown in FIG. 1, the storage box 9 is placed between the cab 2 and the cargo box 3 of the vehicle body 4. A rail (not shown) extending in the left-right direction of the vehicle body is provided in a region on the upper surface of the vehicle body 4 where the storage box 9 is placed. A wheel (not shown) is provided at the lower part of the storage box 9. Then, by placing the wheels of the storage box 9 on the rails of the vehicle body 4 and running, the storage box 9 can be moved in the left-right direction of the vehicle body.

  When the storage box 9 is not moved, the inspection hole provided in the front wall of the packing box 3 is closed by the back surface of the storage box 9. On the other hand, since the inspection hole is provided in the left part of the front wall of the packing box 3, the inspection hole can be opened by moving the storage box 9 to the right side.

  The inspection hole can be reliably closed by providing a mechanism for fixing the storage box 9 at a predetermined position on the front wall of the cargo box 3. For example, a flange that pivots up, down, left and right is provided on the back of the storage box 9 and a flange is provided in the inspection hole, and both the flanges are secured to secure both the storage box 9 and the inspection hole. Can be made.

  Next, the dust loading operation of the garbage truck 1 according to the present embodiment will be described.

  First, the garbage truck 1 is stopped at a predetermined position, and the engine in the idling state is stopped. Next, when the operator turns on a switch for driving the garbage loading device 7, the electric pump 10 is driven by supplying electric power from the storage battery 8 to the electric pump 10. Then, the rotating plate 7a and the pushing plate 7b of the dust loading device 7 are driven by the hydraulic oil supplied from the electric pump 10, and the dust loading device 7 loads dust in the following cycle.

  When the dust G is put into the tailgate 5, the rotating plate 7a and the pushing plate 7b are located on the packing box 3 side (see FIG. 2A). When the dust G is put into the tailgate 5 and the worker presses the loading button, the rotating plate 7a is rotated in the direction of arrow A, and the dust G is lifted to the cargo box 3 side (FIG. 2 ( b) and (c)). When the rotating plate 7a rotates clockwise by a predetermined angle from the loading start position, the pushing plate 7b starts to swing in the direction of arrow B, gradually moves away from the packing box 3, and the rotating plate 7a finishes lifting. When it does, the dust G swept up by the rotating plate 7a will be in the state which can be pushed in in the packing box 3. FIG. Then, when the rotating plate 7a that has lifted up the dust G reaches a substantially horizontal state toward the packing box 3, the pushing plate 7b swings in the direction of the arrow C toward the packing box 3 side, The dust G on the rotating plate 7a is pushed into the packing box 3 (see FIGS. 2D and 2E).

  In the refuse collection vehicle 1 according to the embodiment described above, the rotating plate 7a and the pushing plate 7b of the dust loading device 7 are driven by the electric power supplied from the storage battery 8. Accordingly, it is not necessary to use a part of the engine power as the driving force of the dust loading device as in the conventional dust loading device, so that an “idling stop” at the time of dust loading can be realized. As a result, it is possible to prevent noise and exhaust gas from being generated when dust is loaded, and to save fuel for driving the engine.

  Moreover, in the refuse collection vehicle 1 which concerns on embodiment described above, since it is movable in the front-back direction of a vehicle body within the cargo box 3, it has the dust discharge plate 6 which pushes the dust in the cargo box 3 back, and discharges it. The dust can be discharged from the rear opening. Further, since the storage battery 8 is stored in the storage box provided in front of the packing box 3, the capacity (storage amount) of the storage battery can be increased. Therefore, for example, it is possible to set the amount of stored electricity that can be electrically loaded in one collection operation and replace the storage battery every time the loading operation is performed.

  Further, in the garbage truck 1 according to the embodiment described above, the storage box is disposed between the cab 2 and the cargo box 3 and is movable in the left-right direction of the vehicle body. 9 can be closed and opened in the inspection hole of the cargo box 3 by the movement in the left-right direction of the vehicle body. That is, the storage box 9 can function as a lid member for the inspection hole.

  In the above embodiment, the example in which the present invention is applied to the dust collecting vehicle 1 provided with the rotary plate type dust loading device 7 is shown. However, other types (for example, compression type) of the dust loading device are shown. The present invention can also be applied to a garbage truck equipped with

  Moreover, in the above embodiment, while the cargo box 3 was fixed to the rear part of the vehicle body 4 and the dust discharge plate 6 was provided in the cargo box 3, instead of providing the dust discharge plate 6, It is also possible to provide tilting means for tilting the cargo box 3 so that the rear part is positioned relatively downward with respect to the front part of the cargo box 3. By tilting the cargo box 3 with such tilting means, the dust can be moved to the rear of the cargo box 3 by the action of gravity and discharged.

  When the tilting means for the packing box 3 is employed instead of the dust discharge plate 6 as described above, the storage box 9 is placed at a position slightly separated from the packing box 3 so as not to prevent the tilting of the packing box 3. Secure it after placing it. By arranging and fixing the storage box 9 at such a position that does not prevent the tilting of the packing box 3 in this way, the storage battery 8 is not impacted when dust is discharged due to the tilting of the packing box 3. Further, since the storage battery 8 does not tilt together with the packing box 3, there is no fear of dropping due to tilting, and power can be supplied stably.

  Moreover, in the above embodiment, while the cargo box 3 was fixed to the rear part of the vehicle body 4 and the dust discharge plate 6 was provided in the cargo box 3, the example has been described. On the other hand, tilting means for tilting the cargo box 3 so as to position the rear portion relatively downward can also be provided. By providing both the dust discharge plate 6 and the tilting means, dust can be effectively discharged by the action of the dust discharge plate 6 and the action of gravity.

  When the tilting means is employed together with the dust discharge plate 6 as described above, the storage box 9 is attached to the front surface of the cargo box 3 so as to be movable in the left-right direction of the vehicle body. In this way, by attaching the storage box 9 to the front surface of the cargo box 3 so as to be movable in the left-right direction of the vehicle body, the storage box 9 functions as a lid member for opening and closing the inspection hole. Can be realized.

  Moreover, in the above embodiment, the inspection hole is provided in the left side portion of the front wall of the packing box 3, and a configuration is adopted in which the inspection hole is opened by moving the storage box 9 to the right side. It is also possible to adopt a configuration in which an inspection hole is provided in the right side portion of the front wall of the packing box 3 and the inspection hole is opened by moving the storage box 9 to the left side.

  In the above embodiment, as shown in FIG. 3A, the electric pump 10 is driven by the electric power supplied from the storage battery 8, and the dust loading device is driven by the hydraulic oil supplied from the electric pump 10. Although the example which driven the 7 rotation board 7a and the pushing board 7b was shown, the drive system of these rotation board 7a and the pushing board 7b is not restricted to this.

  For example, an electric actuator for driving the rotating plate 7a and the pushing plate 7b of the dust loading device 7 is provided, and the rotating plate 7a and the pushing plate 7b are driven by driving the electric actuator with electric power supplied from the storage battery 8. (See FIG. 3B).

  Further, a motor 11 driven by electric power supplied from the storage battery 8 is provided, the hydraulic pump 12 is driven by the motor 11, and the rotary plate 7 a of the dust loading device 7 and the hydraulic oil supplied from the hydraulic pump 12 and You may drive the pushing board 7b (refer FIG.3 (c)).

  Further, in a dust loading device other than the rotating plate type (for example, a compression type dust loading device), as shown in FIG. 3B, the hydraulic actuator is replaced with an electric actuator, or as shown in FIG. Alternatively, the electric pump 10 can be replaced with a hydraulic pump 12 driven by a motor 11.

  Further, in the above embodiment, the example in which the tailgate 5 and the dust discharge plate 6 are driven by the engine power extracted by the PTO device has been shown. However, these tailgates are obtained using the power supplied from the storage battery 8. 5 and the dust discharge plate 6 can be driven.

  In addition, in the case where the refuse loading device 1 according to the above embodiment is provided with tilting means for tilting the cargo box 3 so that the rear part is positioned relatively downward with respect to the front part of the cargo box 3. The power supplied from the storage battery 8 can also be adopted as energy for tilting the packing box 3.
