Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a garbage collection vehicle equipped with a loading device composed of a sliding plate and a pushing plate.

Conventionally, in a garbage collection vehicle equipped with a garbage loading device consisting of a sliding plate and a pushing plate, a starting switch is used.

It is known that when the box is pressed, the pushing plate operates in the order of reversing, crushing, compressing, and stuffing, and the garbage is stored in the garbage storage box.

In such garbage collection vehicles, some garbage may not be crushed or compressed properly, and especially during the compression process, the angle formed between the pushing plate and the bottom wall of the storage chamber may rotate beyond a certain level. Otherwise, there is a drawback that it will be impossible to fill the storage box with garbage.

Moreover, even if the garbage loading device is operated again, the pushing plate only compresses the same position of the garbage, so the garbage can no longer be loaded, and each time the worker removes the garbage that is not compressed to the outside. I had to, Ryo 6. I didn't.

The present invention has been developed in view of these problems.One, when the garbage cannot be compressed during the normal operation process, it is possible to change the compression position of the pushing plate at any time even during the operation to perform packing and compaction. The object of the present invention is to provide a garbage loading device for a garbage collection vehicle.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. In FIG. 11, reference numeral 1 denotes a garbage storage box mounted on the body frame of a garbage collection vehicle. The opened input box 2 is connected so as to be tiltable.

The input box 2 has an input port 5 opened at the lower part of the back surface thereof, and a garbage storage chamber 6 formed in the lower part thereof.

The input box 2 is equipped with a garbage loading mechanism that compresses and crushes the garbage and stuffs it into the garbage storage box 1. The structure of this mechanism will be explained below. Guide groove members 7 formed in the shape of a groove are installed on both side walls of the input box 2 so as to be inclined from the upper front end to the lower rear end. The pivot 14 is pivotally supported.

On the other hand, a sliding plate 8 is housed in the input box 2 and extends to the full width IJ, and guide rollers 9 are pivotally attached to the top and bottom of both sides of the sliding plate 8. It is fitted along the inner wall of the groove member 7 so as to be freely removable.

A pivot shaft 1 is attached to the upper rear surface of the sliding plate 8 via a bracket.
6 is pivotally supported, and this pivot 16 extends along the back surface of the guide groove member 7 and beyond a notch 10 formed in the side wall of the input box 2 so as to match the sliding distance of the slider &8. It protrudes outward from the inside of the input box 2. The outwardly protruding pivot 16 and the first telescopic cylinder 11 provided on the outside of the lower part of the input box 2 are connected along the inclination direction of the guide groove member 7 and are deviated upward. 11 allows the sliding plate 8 to reciprocate along the guide groove member 7.

Note that one end 5 of a second telescopic cylinder 15 is also pivotally attached to the pivot shaft 16 pivotally attached to the upper rear surface of the sliding plate 8, as will be described later.

Further, at the lower end of the sliding plate 8, a push plate 12 that extends completely in the lateral direction of the input box 2 is pivoted 16 so as to be swingable back and forth.
A second telescopic cylinder 15 is connected between a projecting piece 14 protruding from the back surface of the pushing plate 12 and a pivot 16 pivotally attached to the upper part of the back surface of the finger plate 8. This allows the pushing plate 12 to swing back and forth around the shaft support 16.

That is, by sequentially controlling the expansion and contraction of these telescopic cylinders 11 and 15, the operations of reversal (b), crushing (0), and compression (d) are performed from the filling completion state shown in FIG. 1(a). be able to.

Next, the hydraulic circuit will be explained with reference to FIG. 2. P is a hydraulic pump, T is an oil reservoir, vl is an electromagnetic switching valve for the first telescopic cylinder 11, 72 is an electromagnetic switching valve for the second telescopic cylinder 15, and 72 is an electromagnetic switching valve for the second telescopic cylinder 15. v1 is solenoid S Q L-
a, S Q L-b, and the electromagnetic switching valve v2 has solenoids S OL-c and S OT--d, respectively.

6 Also, to explain the electrical circuit diagram with reference to Figure 3, 5W
-1 is a changeover switch to select garbage loading work or garbage discharge work, 5W-2 is a start switch for the garbage loading device,
5W-3 is a selection switch for selecting one-cycle operation or continuous-cycle operation of the garbage loading device, 8W-4 is a stop switch, SW-5 is an individual switch for reversing the push plate 12, and 5W-6 is the sliding plate 8. A single swivel for lifting, i.e., stuffing.

In this case, these switches SW-5 or SW
-6 contact operation allows reversing or packing operation from any operating position.

LS-4 is a limit switch that detects the upper limit position of the sliding plate 8, LS-2 is a limit switch that detects the lower limit position of the sliding plate 8, and LS-4 is a limit switch that detects the forward swing limit position of the push plate 12. Detecting IJ Mitsutwitch, TJ8-3
is a limit switch that detects the backward swing limit position.

Among these limit switches, Its-1, LS-
2 is A7 in which an actuating body is arranged on one side and a limit switch is arranged on the other between the garbage input box 2 and the sliding plate 8.

In addition, the limit switches LS-3 and LS-4 are mounted on the sliding plate 8.
It is arranged on the back surface, and switching control is performed by guiding the back and forth rocking of the push plate 12 by a link mechanism.

0R-1, 0R-4, 0R-3, 0R-4, 0R-5,

It has r-4, a r-5, a r-6, and cr-7.

Further, 'I' R-4 and TR-2 are timers, and have contacts tr-1 and tr-2, respectively.

B is a power source 0 Next, the operation process of the embodiment of the present invention will be explained with reference to FIG. 1. The solid line (a) in FIG. In this state, both the first and second telescopic cylinders 11.15 are extended, the sliding plate 8 is in the raised position, and the limit switch LS is
-1 is activated, and furthermore, the push plate 12 is in the forward swing position and the limit switch L8-4 is activated. In this condition? ) flPGo-12402 (3) Inject the garbage into the input box storage chamber 6 from the input port 5, and switch the changeover switch 5W-1 to the upper position as shown in Fig. 3.
When the start switch s w -2 is operated, the relay 0R
-1 and 0R-2 are self-retained and solenoid SOI+-
d is energized. As a result, the switching valve v2 is switched to the left position and only the second telescopic cylinder 15 is retracted, and the push plate 12 is inverted until its front surface is in a substantially horizontal position, as shown by the chain line (b) in Figure 1. let When the push plate 12 reaches the limit reversal position, the limit switch LS-3 is activated, and the relay OR-3 is self-holding, and at the same time, the relay 0R-3 is activated.
2 is de-energized. As a result, the switching valve v2 is returned to the neutral position, and at the same time, the solenoid BOL b is energized to switch the switching valve v1 to the left position. As a result, the first telescopic cylinder 11 is operated to contract, and the process of crushing the garbage begins.
The sliding plate 8 descends along the guide groove member 7, and the pushing plate 12 connected thereto is parallel to the sliding plate 8 while keeping its front surface substantially horizontal, as shown from the chain line (b) to (Q) in FIG. It is possible to push the input kitchen waste between the pushing plate 12 and the arcuate surface of the bottom of the input box 2.

When the push plate 12 reaches the lowering limit position, the limit switch 1
Since relay 8-2 is activated, relay 0R-4 is self-held, and at the same time, the energization of relay 0R-3 is canceled. Therefore, current is applied to the solenoid 5QL-0, returning the switching valve v1 to the neutral position and simultaneously urging the switching valve V2 to the right position. Therefore, from the state where the crushing of the garbage is completed as shown by the dashed line (0) in FIG.
As shown in the figure, the pieces rotate clockwise until their front surfaces become almost vertical and enter the compression stroke, and the crushed pieces that were temporarily crushed in the previous stroke are pushed between the pushing plate 12 and the flat surface of the bottom of the charging box 2. Then, due to the action of the link mechanism, the limit switch -8
-4 is switched, and relay 0R-5 is self-held, and at the same time, the energization of relay 0R-4 is canceled.

As a result, the first telescopic cylinder 11 is extended from the end of the compression stroke shown in the chain line (d) in FIG. It rises parallel to the ground, and the garbage compressed in the previous step can be stuffed into the garbage storage box 1.

Note that (0) from the inversion completed state shown in FIG. 1(b)
In the crushing process leading to this, the contact operation of limit switch L8-3, which detects the end of reversal, causes relay 0R-3 to self-hold as described above, but at the same time, timer TR-2 continues to be energized. As a result, the sliding plate 8 starts descending, and when the set time has elapsed, the contact tr-2 closes and the relay 0R-7 is activated.

Therefore, the relay 0R-4 is energized through the contact 0r-7, the relay 0R-3 is de-energized to stop the lowering of the sliding plate 8, and then the relay 0R-4 is energized through the contact 0r-4 as described above. The process moves to a compression stroke using the pushing plate 12.

In this way, the sliding plate 8 is prevented from descending by the dust,
Even if the crushing limit position A11 cannot be reached, that is, even if the limit switch TJS-2 is not switched, it is possible to proceed to the next compression stroke after a certain period of time has elapsed.

Also, when relay 0R-4 is energized and shifts to the forward return stroke, limit switch l5-3 is switched and 0R-
Since the power to the timer TR-1 is cut off, the timer TR-1 continues to be powered through the contact ar-'7. Then,
After a certain period of time has elapsed, relay 0R76 is activated via contact tr-1, and relay 0R- is activated via contact cr-6.
5 is energized and self-maintained.

Therefore, since the power supply to relay 0R-4 is cut off, the compression stroke by the pushing plate 12 is stopped, and the sliding plate 8 is raised.
In other words, the process moves to the stuffing process.

In this way, even if the pushing plate 12 is prevented from being compressed by dust and cannot reach the compression limit position, that is, even if the limit switch L S-4 is not switched, it is possible to proceed to the next stuffing stroke. can. By the way, storage chamber 6
If the garbage thrown into the container cannot be compressed by the crushing stroke or the compression stroke (Fig. 5), the timer T R-1 is activated and the process moves to the stuffing stroke, but the pushing plate 12 is at least in a substantially vertical state. Unless it is rotated around the pivot support 16 to a position close to , it is impossible to fill the storage box 1 with garbage.

In this case, the individual packing switch 5W-6 may be operated in contact. This contact action causes solenoid 5QL-)
＞ is directly energized, and the solenoid 5QL- due to the compression stroke
In conjunction with the energization to 0, the pressure oil from the hydraulic pump P causes the second telescopic cylinder 15 to extend with the drained oil that has extended the first telescopic cylinder 11.

From this, the pushing plate 12 rises while continuing the compression stroke. In other words, in order to start the packing process, the garbage is compressed in a chewing manner at different locations (
(FIG. 6), the dust that could not be compressed in the normal sequential operation is compressed at the tip of the pushing plate 12. As a result, the push plate 1
2 rotates in a substantially vertical position, and garbage can be packed into the storage box 1.

In addition, if it is necessary to reverse the push plate 12, just operate the &13 independent switch for reversing SW-a,
The aforementioned individual packing switches SW-5 and St w-6 can be used selectively depending on the type of garbage.

As described above, according to the present invention, by disposing a separate switch for loading in the electric-hydraulic control device that controls the garbage loading device, garbage that cannot be compressed in a normal garbage processing cycle can be moved to a location. This makes it possible to compress the material by changing the amount, which helps improve the workability of garbage collection trucks.
