Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a garbage collection vehicle. In a garbage loading device for a garbage collection vehicle, in which a tailgate is pivotally attached to the opening of a loading box that stores garbage so that it can be opened and closed, the tailgate is closed when loading garbage, the loading mechanism inside the tailgate is operated, and the loading box is opened and closed. The tailgate is designed to rotate upward when discharging dust from the vehicle.

However, with this type of garbage loading device,
The tailgate, including the bottom sump section and side panels, is quite large and heavy, and it requires a considerable amount of power to rotate it upwards with a dump cylinder, etc. to discharge dust, and it also has a large weight. There is a danger that the tailgate may fall from its raised position. Furthermore, the sump part of the tailgate is constructed integrally with the side plate, and each time the tailgate is opened, the sump part separates from the lower edge of the cargo box opening part. Sewage in the garbage tends to leak at the joint of the box opening.

The present invention aims to solve the above-mentioned safety and hygiene problems of the known technology.

Next, embodiments of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a packing box of a garbage collection vehicle, inside which garbage is collected. Packing box 1
Both side walls 1a extend rearward and downward from the opening at the rear end of the packing box to form extended side plates 2, and the bottoms of these side plates 2 are integrally connected by a bottom plate 3. There is. The bottom plate 3 is integrally connected to the floor 1b of the cargo box 1, and is curved downward from the floor 1b to form a sump section 4 for garbage. The lower portions of both side plates 2 are integrally connected by a connecting member 5 at the rear edge of the bottom plate 3.

A shape member 6 is fixed to the upper part of the opening of the packing box 1,
The upper end portions of both side plates 9a of the tailgate 9 are pivotally connected to the bracket 7 fixed thereto by means of a pivot pin 8. The tailgate side plates 9a are integrally connected to each other by a panel-shaped deflector 10 on the side of the cargo box 1, and are connected by a connecting member 11 at the lower end of the side opposite to the cargo box. The tailgate side plate 9a is provided so as to be in contact with the inside of the side plate 2 of the sump portion 4.

The side plate 2 of the sump portion 4 is formed hollow, and a driven wheel 12 is provided inside the side plate 2 . This driven wheel 12 consists of a sprocket wheel, for example,
It is driven by a drive source 13 such as a hydraulic motor provided below the cargo box via a transmission element 14 such as a chain. The rotating shaft 15 of the driven wheel 12 projects inside the side plate 2, and both ends of one longitudinal side edge of the conveyor panel 17 are fixed thereto. Therefore, by operating the drive source 13, the conveyor panel 17 can be rotated so that its leading end traces a trajectory 17a in FIG. 2.

A pivot 19 (second
As shown in the figure, a ram panel 20 is pivotally mounted. The lapel 20 has a panel portion 20a extending downward from the pivot 19, and a portion 20b extending obliquely upward from the pivot 19.
The lower end of a piston rod 22a of a ram cylinder device 22 is pivotally connected to the tip of the piston rod 22a by a pivot pin 21. The upper end of the ram cylinder device 22 is pivotally connected to the aforementioned bracket 7 by a pivot pin 23.

A contact protrusion 24 is formed on the inner surface of the tailgate side plate 9a at a position where the upper surface of the portion 20b comes into contact when the ram panel rotates from the position of the ram panel 20 shown by the solid line in FIG. 2 to the position of the ram panel shown by the chain line. It is integrated.

Note that 25 is a locking member for fixing the tailgate side plate 9a to the sump part side plate 2.

As shown in FIG. 3, a discharge plate 26 is provided inside the cargo box 1 and is movable forward and backward toward the opening thereof.

In the above configuration, in order to load garbage, the conveyor panel 17 is rotated clockwise in the state shown in FIGS. 1 and 2. As a result, its tip is displaced along the bottom plate 3 of the sump section 4 and scrapes the garbage dumped thereon. During this scraping operation, the ram panel 20 is displaced from the solid line position in FIG. 2 to the chain line position. Then, when the conveyor panel 17 rises to the solid line position in FIG.
Push the garbage on top into packing box 1.

In order to discharge the garbage collected in the packing box 1 as described above, the locking member 25 is unlocked,
The ram cylinder device 22 is deflated. As a result, the ram panel 20 rotates counterclockwise, and its portion 20b comes into contact with the protrusion 24. When the ram cylinder device is further contracted, the contraction force is applied to the protrusion 2
4 on the tailgate 9, the tailgate 9 is opened in the direction of arrow A to the position shown in FIG. In this state, the discharge plate 26 is advanced to the position shown by 26A in FIG. 3 using a hydraulic device (not shown) to discharge the garbage in the cargo box 1. At this time, some of the dust falls into the sump section 4 and remains there.

Therefore, the conveyor panel 17 is reversed counterclockwise to push out the garbage in the sump section 4, and the conveyor panel 17 is stopped at the chain line position in FIG. 3, and the discharge plate 26 is moved to the position shown by 26B. advance. This completes the discharge of the garbage, so return the discharge plate 26 to the initial position, rotate the conveyor panel 17 clockwise and return it to the solid line position, extend the ram panel 22, and extend the tailgate 9.
After lowering the tailgate 9, use the locking member 25 to close the tailgate 9.
to the side plate 2 of the sump section.

In the modified embodiment shown in FIG. 4, the side plate 2 of the sump part 4 is cut out to a considerably lower position as shown at 2a, and a protrusion 27 with a hole through which the locking member 25 acts is formed on the upper edge 2a of the side plate 2. It stands out from the rest.

In the present invention, the embodiments of which have been described above, the weight of the tailgate is reduced by opening the bottom of the tailgate and removing the sump of the tailgate, and instead, a sump portion that functions as a tailgate sump is provided. The conveyor panel and its drive mechanism, which form part of the garbage loading mechanism, are supported by the sump section on the vehicle body side, and the garbage loading mechanism is attached to the tailgate itself. Since only the ram panel and ram cylinder device are supported as other parts of the ram panel, the tailgate itself is extremely light while fulfilling the functions of a conventional tailgate-type garbage loading device, reducing the power required to operate the tailgate. It is possible to reduce the risk of falling and to reduce the risk of falling.

In the present invention, by supporting the conveyor panel, its drive mechanism, and the sump section on the vehicle body side separately from the tailgate that moves up and down, the output for the up and down movement of the tailgate is greatly reduced. be able to. Moreover, in the present invention,
The sump section with the mechanism of the tail gate section is always integrally connected to the cargo box, and the bottom plate is curved and recessed in the middle, so leakage of waste liquid is completely prevented. In addition, even if the sump part is integrated with the cargo box, the discharge plate allows garbage to be discharged from the cargo box without any problem.Furthermore, the conveyor panel drive mechanism supported by the fixed sump part can be moved up and down by the tailgate. Since there is no accompanying vertical movement, failures are less likely to occur and operation is stable.
