Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a dumping box device and a method of operating a dumping box in a garbage receiving place for dumping garbage collected by a garbage truck.

[0002]

2. Description of the Related Art Generally, garbage collected by a garbage truck is dropped into a hollow garbage pit formed in a garbage receiving area, and thus the garbage accumulated in the garbage pit is collectively incinerated. However, since the garbage pit is formed in a concave shape having a depth of, for example, 10 meters (m) to 20 meters from the ground, it is dangerous to drop garbage directly into a garbage pit from a general vehicle without a dump function. Is expected to accompany. For this reason, garbage of general vehicles is provided with a dumping box on a platform which is a garbage entrance of the garbage pit, the garbage is temporarily transferred to the dumping box, and then the garbage transferred to the dumping box is dropped into the garbage pit. , So that trash can be safely dropped. As such a damping box, one as shown in FIG.
Is pivotally supported on the frame via a support shaft 20 disposed below the tip of the dust pit 3 so that the base end of the dumping box 19 can swing upward. One end of the operating arm 21 which expands and contracts by force is pivotally supported on the upper portion on the tip end side of the dumping box 19, and the other end is pivotally supported on the platform 2 which is the entrance of the dust pit 3. By swinging the rear end of the dumping box 19 upward with the extension of the operation arm 21, the dumping box 19 is brought into a dropping position in which the tip of the dust pit faces downward. It is configured to drop from the opening formed on the part side and drop to the dust pit 3 side.

[0003]

Since the conventional dumping box 19 swings around a support shaft 20 located outside of the dust pit 3, the dumping box 19 is set to the above-described dropping posture. In some cases, dust may drop not only on the dust pit 3 side but also on the platform 2 side. In this case, the garbage falling on the platform 2 side emits offensive odor. Therefore, even if the odor prevention door 4 is closed to separate the garbage pit 3 from the platform 2, the odor is generated on the platform 2 side. There is. Moreover, the dust falling to the platform 2 side may be located at the lower part of the dumping box 19 by returning the dumping box 19 from the dropping posture to the original posture in which the dust can be received. There is a problem that it is difficult to push the trash to the trash pit 3 side and drop it. On the other hand, it is conceivable to dispose the spindle of the dumping box in the dust pit and arrange the tip of the dumping box in the dust pit to solve the above problem.
In this case, since the tip of the dumping box is always located in the garbage pit, there is a problem that the garbage entrance of the garbage pit cannot be closed by the odor prevention door, so that it cannot be adopted. There is a problem to be solved by the present invention.

[0004]

FIG. 1 shows an embodiment of the present invention.
The description will be made based on the drawings shown in FIGS. In the drawing,
Reference numeral 1 denotes a dumping box device to which garbage collected by a garbage truck is transferred. The dumping box device 1 includes a platform 2 through which a garbage truck enters and exits.
The platform 2 is provided in a garbage receiving area composed of a garbage pit 3 formed in a mortar-shaped concave hole by digging down a floor surface (ground) of about 20 m. Incidentally, the platform 2 and the garbage pit 3 are separated by a pair of left and right odor prevention doors 4 which open and close in a double-opening manner in the front-rear direction, and are used only for dumping garbage to the garbage pit 3 by the dumping box device 1. The door 4 is set to open.

A mounting recess 5 is formed on the floor of the platform 2 at the front of an odor prevention door 4 which serves as a garbage entrance for the garbage pit 3, and the mounting recess 5 is provided with a damping box of the present invention. A dumping box 6 constituting the apparatus is arranged, and refuse unloaded from a general vehicle having no dumping function is temporarily transferred to the dumping box 6. Here, the mounting recess 5
The edge of the bottom surface 5a of the dust pit 3 side (front side) is formed so as to follow the inclined surface 3a of the dust pit 3 and has a stepped shape. An outer cylindrical body (corresponding to a base of the present invention) 7 having a rectangular cylindrical shape is provided on both right and left sides of the bottom surface 5a of the mounting recess.
a is directed in the front-rear direction and the opening is close to the dust pit 3 side. The length of the outer cylinder 7 in the front-rear direction is set shorter than the length of the damping box 5 in the front-rear direction. 8 is the outer cylinder 7
An inner bar (corresponding to a slide member of the present invention) which is internally fitted and supported in the cylindrical hole 7a of the inner bar 8a.
Is formed in a prism shape longer in the front-rear direction than the outer cylinder 7, and the front portion (the tip on the dust pit side) is
It is arranged so as to protrude from. Further, a spacer 7b is interposed between the inner bar 8 and the outer cylinder 7, and the inner bar 8 is configured to be slidable (slidable) in the front-rear direction with respect to the outer cylinder 7. On the other hand, a long hole 7c long in the front-rear direction is formed on the rear side of the outer cylindrical body 7, and an engaging protrusion 8a protruding from the rear of the inner bar 8 is movably fitted in the long hole 7c. are doing. Thus, the inner bar 8 is engaged with the outer cylindrical body 7 from the inactive position where the engaging projection 8a engages with the rear end edge of the elongated hole 7d. It is set so that it slides between the operating positions where it is combined.

Although the duping box 6 is box-shaped, a side portion (front side portion) on the dust pit 3 side is removed and formed in an opening 6a. When the dumping box 6 in the original position in which the dust is transferred is in a dropping position in which the rear end side swings upward, the dust is set to drop by its own weight from the opening 6a. On the lower surface of the bottom of the dumping box 6, projecting pieces 6b are formed integrally on the left and right sides of the front end (the end on the dust pit 3 side) and project downward. The base ends of the swing support shafts 9 whose parts project outward from the left and right side surfaces of the damping box are integrally supported. On the other hand, the inner bar 8
A bearing bracket 8b is integrally provided on the upper surface of the front end of the swinging support shaft 9. The protruding distal end of the swing support shaft 9 is rotatably supported on the bearing bracket 8b, whereby the damping box 6 and the inner The bar 8 is set so as to be swingable at the lower end of the dumping box 6 and at the tip end on the dust pit 3 side. Further, on the bottom lower surface of the damping box 6, rollers 6c are respectively supported on the left and right sides of the rear end portion, and each roller 6c is set so as to be guided to travel on the upper surface of the outer cylindrical body 7. ing.

[0008] Support brackets 6d projecting from the left and right outer sides of the damping box 6 are provided at the front end and above and project to the left and right sides. The driving means is connected. In other words, the operating arm 10 that constitutes the driving means is provided with the cylinder cylinder 10a and the cylinder rod 10b that fits inside the cylinder cylinder 10a so as to be able to protrude and retract at the front end side (front end side). When the electric motor 11 is driven, the cylinder rod 10b is moved in and out of the cylinder cylinder 10a, so that the entire length of the operation arm 10 is set to expand and contract. Then, the distal end of the cylinder rod 10b (the front end of the operating arm 10) is connected to the support bracket 6d of the damping box 6.
While supporting the base end of the cylinder cylinder 10 (the rear end of the operating arm 10) via a substantially L-shaped support arm 12 fixedly supported by the side surface 5 b of the mounting concave hole 5. The operating arm 10 is supported so as to be freely swingable in the vertical direction, so that the operating arm 10 is extended and contracted between a fixed member (a member fixed to the mounting recess 5) and the damping box 6 as a movable member. With this configuration, the upper end on the distal end side of the damping box 6 is set to be pushed and pulled with the expansion and contraction of the operation arm 10 based on the driving of the electric motor 11, and thus the driving means is configured. .

Next, the operation of the damping box 6 will be described. In normal times, the dumping box 6
The roller 6c at the rear end is in contact with the upper surface of the outer cylindrical body 7, and is in the original posture in which dust can be received.
Further, in this state, the inner bar 8 is located at a non-operation position where the inner bar engaging projection 8a is engaged with the rear end edge of the outer cylindrical body long hole 7c. (Front end) part closes for odor prevention door 4
But is located outside the dust pit 3, and this position corresponds to the retreat position of the dumping box 6 of the present invention. Then, from this state, the odor prevention door 4
Is released, and the electric motor 11 is driven to extend the operating arm 10, so that the damping box 6 is slid so as to be pushed forward. The slide movement is set so as to run on the upper surface of the reference numeral 7. Further, at this time, since the damping box 6 is connected to the inner bar 8 via the support bracket 6d, the swing support shaft 9, and the bearing bracket 8b, the inner bar 8 is forcibly slid forward and the inner bar 8 is moved. Along with the sliding movement of the abutment portion 8a to an operating position (a state corresponding to FIG. 4) where the front end edge of the outer cylindrical body hole 7c is engaged, the inner bar 8 is restricted from sliding forward. The setting is such that the forward sliding movement of the dumping box 6 is restricted. When the inner bar 8 is located at the operation position, the dumping box 6 has a positional relationship in which the front end on the dust pit 3 side enters the dust pit 3 from the opened odor prevention door 4. The dumping box 6
Is set as the forward position according to the present invention.

When the operating arm 10 is further extended while the damping box 6 is located at the forward position, the forward movement of the damping box 6 is restricted. Cylinder 10
a, while rocking the base end of the cylinder rod 10b in the vertical direction and the front end of the front end of the damping box 6 forward.
Is set so that the rear end portion swings upward with the swinging shaft 9 pivotally supported at the lower end portion as a fulcrum, and changes to a dropping posture (a state corresponding to FIG. 5). Incidentally, the return of the dumping box 6 from the dropped posture to the original posture is performed by the operation arm 1.
First, the damping box 6, which is in the dropping posture in the forward position, swings downward, whereby the roller 6d comes into contact with the upper surface of the outer cylinder 7, and slides rearward in this state. Then, it is set to move to the evacuation position and then return to the original posture.

In the embodiment of the present invention configured as described above, refuse from a refuse collection vehicle having no dumping function is temporarily transferred to the dumping box 6, and the rear end of the dumping box 6 is moved upward. In this case, the dust naturally falls from the opening 6a in front of the dumping box 6 to the dust pit 3 side. In this case, the damping box 6 is provided with a odor prevention door having a closed front end. 4 from the retracted position located outside the garbage pit 3 through the open odor prevention door 4 to the garbage pit 3
And displaced to a forward position in which the rear end portion moves upward at the forward position. As a result, the opening 6a of the dumping box 6 in the dropping posture is in the dust pit 3
The dust that naturally falls from the portion is surely dropped into the dust pit 3, falls into the mounting recess 5 behind the dust pit 3, and the odor preventing door 4 is moved. Even if the door is closed, garbage remains on the platform 2 side, thereby preventing a problem that a bad smell is generated. Moreover, in this case, the dumping box 6 is displaced to the forward position where the dumping box 6 is moved into the dust pit 3 beyond the odor prevention door 4 only when the dust is dropped, so that the dumping box 6 is always located between the platform 2 and the dust pit. Therefore, the odor preventing door 4 can be attached to the entrance and exit of the garbage pit 3.

Further, in the above-described embodiment, the sliding movement of the damping box 6 in the front-rear direction and the vertical swing at the forward position are performed between the frame (mounting recess 5) and the damping box 6. Actuating arm 1 provided on
Since the operation is performed in accordance with the operation of extending 0, it is not necessary to provide each driving member as in the case where the operation in each direction is configured by using different driving means. The number of points can be reduced and the structure can be simplified.

The present invention is, of course, not limited to the above-described embodiment, but it is of course possible to configure the sliding operation and the swinging operation of the damping box to be operated by a special driving member. As such, FIG.
The second embodiment shown in FIG. In other words, this device has a configuration in which the gantry 13a on which the damping box 13 is placed is slid in the front-rear direction by the extension operation of the first operating arm 14 provided between the mounting recess 13 and the gantry 12a. The gantry 13a and the damping box 13 are
Is swingably connected via a swinging support shaft 13b disposed at a lower front portion of the damper, and further extended by a second operating arm 15 provided between the gantry 13a and the upper front end of the damping box 13. The rear end of the damping box 13 swings upward about the pivot 13b. Also in this case, after the damping box 13 is slid to the forward position, the rear end portion is swung upward at the forward position, and the damping box 13 is moved forward.
Can be set in a dropping posture in a state where the front end is located in the dust pit.

Next, a third embodiment shown in FIG. 7 will be described. This is provided with a pedestal 17 in a mounting recess 16 formed in the platform 2, and the pedestal 17 is configured to move up and down via a pantograph-type mechanism based on driving of a telescopic first operating arm 18, and A slidably movable and swingable damping box 6 similar to that of the first embodiment is disposed on the gantry 17. With this configuration, dust can be prevented from falling into the mounting recess 16 and dust can be reliably removed from the dust pit 3.
In addition, the height of the dumping box 6 can be adjusted, and the work of transferring dust from a general vehicle to the dumping box 6 can be facilitated, so that the burden on the operator can be reduced.
