May be. In this case, in the conventional rotary refuse collection vehicle, when the rotary plate 6 is rotated from the horizontal position substantially flush with the rear height of the trash container 1 to the avoidance position of about 45 degrees, the pushing plate 8 is rotated.
Is swung rearward from the forward position, so that the rear end opening of the dust container 1 is long (while the rotating plate 6 rotates about 315 degrees from the avoidance position of about 45 degrees to return to the horizontal position). )
It is open and a lot of trash goes back to the trash input box 4 side,
There is a problem that hinders the next garbage loading operation.

SUMMARY OF THE INVENTION An object of the present invention is to provide a rotary refuse collection vehicle capable of suppressing the return of small loose garbage (empty cans, bottles, etc.) and resilient refuse to the refuse input box side.

[0007]

According to the present invention, in order to achieve the above-mentioned object, the dust put in the dust input box is disposed inside a dust input box which is openably and closably attached to a rear opening of the dust container. A rotating plate that lifts up to the height of the rear opening of the storage box,

The detection switch is connected in parallel to the return start detection switch, and can be switched on and off by the changeover switch. If necessary, the changeover switch connects the return start delay detection switch to the return start detection switch, and The return start is delayed.

[0009]

FIG. 1 is a block diagram showing an embodiment of the present invention.
A description will be given based on FIG.

FIG. 1 shows a return control mechanism of a pushing plate in a rotary refuse collection vehicle according to the present invention. In FIG. 1, reference numeral 13 denotes a cam plate fixed to one end of the rotating shaft 5 and rotates integrally with the rotating plate 6. Reference numeral 14 denotes a detection switch for starting the return of the push plate 8 fixed via a bracket 16 to a switch mounting base 15 mounted on the frame of the dust box 4 and is a normally open proximity switch. A position in which the cam plate 13 approaches and closes the contacts only while rotating from the horizontal position to the avoidance position of about 45 degrees, and a position where the cam plate 13 separates and opens the contacts when the rotating plate 6 rotates to the avoidance position of about 45 degrees. Stick to Reference numeral 17 denotes a detection switch for delaying the return of the push plate 8 fixed to the switch mounting base 16 in the vicinity of the detection switch 14 for retreat start via the bracket 18. The cam plate 13 is in close proximity and the contact is closed only during the rotation from the position before the avoidance position of about 45 degrees to the avoidance position of about 180 degrees, and the rotating plate 6 is rotated by about 18 degrees.
When the cam plate 13 is rotated to the 0-degree avoidance position, the cam plate 13 is separated and fixed at a position where the contact is opened. The return start delay detection switch 17 is electrically connected in parallel with the return start detection switch 14, and is retracted by a changeover switch (not shown) disposed at an arbitrary position (for example, a dust bin or the like). The electrical connection with the start detection switch 14 can be interrupted.

Next, the operation of loading dust in the rotary dust collection vehicle of the present invention will be described.

First, when general garbage is pushed into the garbage storage box 1, the changeover switch electrically disconnects the return start detection switch 17 of the push-in plate 8 from the retreat start detection switch 14. Is loaded. Then, as in the conventional case, dust is loaded in the manner shown in FIGS. 4A to 4F, and the dust is pushed into the dust storage box 1.

Next, in the case where small loose garbage such as empty cans and bottles and garbage having resilience are pushed into the garbage storage box 1 with a special purpose or mixed with general garbage, a changeover switch is used to delay the return start of the pushing plate 8. The detection switch 17 is electrically connected to the reverse start detection switch 14, and the refuse is loaded in this state. Then, by the cooperation of the reverse start detection switch 14 and the return start delay detection switch 17, as shown in FIG. 2, when the rotary plate 6 rotates to the avoidance position of about 180 degrees, the push plate 8 is moved from the forward position. Swing backward. As a result, the rear opening of the dust container 1 is closed by the pushing plate 8 until the rotary plate 6 rotates from the horizontal position to the avoidance position of about 180 degrees. The rotation plate 6 is shortened during the rotation of about 180 degrees from the avoidance position of about 180 degrees to return to the horizontal position, so that it is possible to suppress the return of the dust to the dust input box 4 side, and to prevent the dust from being inserted from the dust input port to the outside. Can be prevented by the rotating plate 6.

In the above-described embodiment, the pushing plate 8 is swung backward from the forward position when the rotating plate 6 is rotated to the avoidance position of about 180 degrees. The period during which the opening is open is shortened, and the garbage input box 4 for garbage
If the return to the side can be suppressed, the avoidance angle of the rotating plate 6 for swinging the pushing plate 8 backward can be any number of times.

[0015]

As described above, in the rotary refuse collection vehicle of the present invention, the start of the return of the push plate is delayed by the changeover switch as necessary, thereby shortening the period during which the rear opening of the refuse storage box is open. In the case where small loose garbage such as empty cans and bottles and resilient garbage are pushed into the garbage storage box after mixing with dedicated or general garbage, reversion of the garbage to the garbage input box side is suppressed. At the same time, it is possible to prevent the dust from being thrown out from the input port of the dust input box, so that the next operation of loading the dust can be smoothly performed, and a great improvement in workability can be expected.
