Description

[Detailed Description of the Invention] The present invention relates to a garbage input device in a garbage pit of an incinerator.

In incinerator facilities for municipal waste, etc., as shown in Figure 1, garbage a brought in by a garbage truck 1' is temporarily stored in a garbage pit 2', and this garbage a is placed in the upper part of the pit. Using the crane 3', the incinerator is loaded into the charging hopper 4' of the incinerator body.
The garbage is sent to the combustion section 5' in the furnace by a chute for incineration, and a garbage truck 1' approaches the garbage pit 2' at a required height on one side of the garbage pit 2' in order to throw the garbage into the pit. A garbage input gate 7' is provided which is continuous with a platform 6'.

However, when dumping garbage, if the garbage truck 1' is a dump truck type with a dumping function,
Garbage can be dumped directly into the pit from the garbage truck 1' with the door of the garbage input gate 7' open, but if the garbage truck 1' does not have a dumping function, the garbage input gate 7' is opened. It is inefficient to manually scrape out and fill the pit with a scoop, etc., and it also causes problems such as odor leaking out from inside the pit, safety of the worker, and outside air entering the pit. As shown in the figure, a dumping box 8' is installed on the floor outside the garbage input gate 7', and after the garbage from the garbage truck 1 is temporarily stored in this dumping box 8', the door 9' of the garbage input gate 7' is opened. is opened as shown by the dashed line in the figure by a hydraulic cylinder mechanism, etc., and in this state, the damping box 8' is rotated and raised about the pivot point below the pit side end by the hydraulic cylinder mechanism, etc. provided below. (dashed line in the figure), the garbage is thrown into the garbage pit 2' from the discharge port at the end of the pit.

However, in the case of the above-mentioned dumping box structure, it is necessary to open the door of the garbage input gate quite widely, and since the opening/closing action of the door and the rotational raising action of the dumping box are performed separately, the opening time of the gate is This increases the length of time, which not only poses problems in terms of odor leakage and safety, but also requires two drive means, the door and the dumping box, which requires a large number of parts and increases the cost of the equipment.

The present invention has been devised to eliminate the above-mentioned conventional drawbacks of using a dumping box as a garbage input device in the garbage pit of an incinerator, and to simplify the structure so that garbage can be input efficiently and safely. A dumping port having a lower surface sloping downward toward the pit side is provided on the floor of the garbage input gate, and a dumping box capable of blocking the dumping port is made slidable toward the inside of the pit, and the pit side can be lifted up. Furthermore, the door of the garbage input gate is pivoted at a predetermined position on the ceiling so that it can freely rotate upwards inside the pit, and the lower end of the door is attached to the pit side end of the dumping box so that it can be rotated by a hinge structure. The damping box is characterized in that the damping box is connected so that the door can be rotated upwardly inside the pit, so that the damping box slides inward of the pit while its end on the pit side is lifted to perform a damping action. It is.

Next, an embodiment of the present invention will be explained based on FIGS. 3 to 5.

As in the past, the garbage pit 2 is provided with a garbage input gate 7 at a required height on one side thereof, which is connected to a platform 6 through which the garbage collection vehicle 1 enters and which is connected to the platform 6 through a barrier wall 10 which also serves as a vehicle stop. There is. On the floor of the garbage input gate 7, there is a drop opening 12 having a required width and having a triangular cross section and having a lower surface 11 sloping downward toward the pit and communicating with the inside of the pit.
A damping box 20 that can close the drop-in port 12 is installed to be able to slide inward into the pit and lift at least the pit side, as shown in the figure. In the case of the embodiment, there are supporting members 13, which serve as rails, on both sides of the drop-in port 12 in the floor.
13 is fixedly installed, and the supporting member 13,1
A damping box 20 is placed on top of the damping box 3. Although both ends of the damping box 20 can be placed directly on the supporting members 13, 13, as shown in the figure, rollers 1 are placed at both lower ends of the platform 6 side end, that is, the rear end of the damping box 20.
4, 14, and placing the rollers 14, 14 on the supporting members 13, 13 is suitable for the sliding operation. It is also desirable to provide a portion on the pit side end of the damping box 20 to rest on the supporting members 13, 13. The rear end side of the dumping box 20 is provided as a garbage discharge port 21, which is opened as shown in the figure or can be opened by a side plate pivotally supported on the upper edge. In either case, the flange 22 on the upper edge of the rear end is provided so as to rest on the upper surface of the shielding wall 10, and the damping box 20 and the shielding wall 10 are
Prevents odor from escaping from the gap between the

The door 9 of the garbage input gate 7 has its upper end pivoted 16 at a predetermined position on the ceiling 15 so as to be rotatable upwards inside the pit, and its lower end is connected to the end of the dumping box 20 on the pit side. are rotatably connected by a hinge structure,
The damping box 20 is lifted from the pit side by the pivoting action of the door 9 upwards inside the pit, and slides toward the inside of the pit, and the damping box 20 also returns to its original position by the pivoting return action of the door 9. ing. 17 is damping box 2
0 and door 9 are shown. In the case of the illustrated embodiment, the door 9 has an inclined upper part 9a and a hanging lower part 9b connected by a hinge connecting part 18. The lower part 9b is always maintained in a hanging state so that the door 9 is not strained due to the lifting load of the damping box 20.

Reference numeral 19 denotes a hydraulic cylinder mechanism serving as a means for rotating the door 9. An output rod 19a of the cylinder mechanism 19 is connected to the outside of the upper part 9a of the door 9, and the door is moved by the forward and backward action of the rod 19a. 9 rotates and returns to the inside of the pit upwards. Note that the means for rotating the door 9 is not limited to the one that uses the cylinder mechanism described above.

The present invention is constructed as described above, and when loading garbage carried in by the garbage truck 1,
After the garbage a is transferred from the garbage truck 1 into the dumping box 20 with the door 9 of the garbage input gate 7 closed, the door 9 may be rotated upward and inside the pit as shown by the chain line in FIG. 3. , this door 9
In conjunction with the rotation of the dumping box 20, the side connected to the door 9, that is, the pit side, is lifted and tilted, and the angle of inclination increases with the upward movement, and the rear end of the damping box 20 is installed. The dumping box 20 slides inward while remaining in contact with the dumping box 20, and due to the inclination of the dumping box 20, the dust in the box finally falls from the discharge port 21 at the rear end to the drop in port 12, and the inclination of the dump port 12 Bottom surface 1
1, the garbage is thrown into the garbage pit 2.
After throwing in the garbage, when the door 9 of the garbage input gate 7 is rotated downward, the dumping box 20 will slide toward the platform 6 and the pit side end will move downward to return to its original state. return to position,
The dumping port 12 is blocked by the dumping box 20, and the door 9 of the garbage input gate 7 is closed.
is kept closed.

As described above, according to the garbage input device of the present invention,
By linking the garbage input gate door and the dumping box, the garbage input gate and dumping port can be opened and closed in one operation, and at the same time garbage can be loaded from the dumping box. Not only is it easier to operate compared to the conventional method in which the dumping box and dumping box were operated separately, but the opening time of the garbage input gate and waste inlet can be significantly shortened. Since the connected end of the pit can be lifted up, there is no need to open the gate widely, and the opening of the drop-in port can be reduced, which reduces the outflow of odors from the garbage pit and makes it safer. It has high performance and is easy to work with. Furthermore, since the driving means for operating the door and damping box is located in one place, the number of parts is small, and the cost required for equipment is low, making it economical.
