Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a storage and discharge device for garbage, and particularly to a storage and discharge device that can temporarily store garbage and supply the garbage to a compactor or the like as appropriate.

(Prior art) Conventionally, garbage discharged from a garbage truck is temporarily stored, and the stored garbage is transferred to a container via a compactor or supplied to an incinerator. The device is known.
For example, as seen in Japanese Patent Application Laid-open No. 54-98059, a garbage storage and discharge device has a hopper discharge port that faces the input port of the compactor and communicates with it, and a transfer plate that is movable back and forth inside the hopper. By sliding this transfer plate, the garbage stored in the hopper can be supplied from the input port to the front of the compactor.

(Problem to be Solved by the Invention) By the way, when garbage is dumped into a hopper from a garbage collection vehicle, it becomes clogged as it goes below the hopper, and the garbage also contains large garbage such as kitchen waste and miscellaneous garbage. Due to its low specific gravity and poor fluidity, it is easily compressed during discharge and tends to form blocks.

Therefore, when the dust is discharged by the transfer plate, a "bridging phenomenon" occurs in which the inner wall surfaces of the hopper above the input port are bridged.

For this reason, in the garbage storage and discharge device, a bridging elimination device that removes bridging phenomenon is installed facing the input port of the compactor, assuming that the bridging phenomenon occurs, and the bridging elimination device is activated each time the garbage is discharged by the transfer plate. There was a problem of poor work efficiency.

(Means for Solving the Problems) The present invention has been made in view of the above points, and provides a garbage storage and discharge device in which the hopper has a structure that makes it difficult for the bridging phenomenon to occur in consideration of the properties of the garbage. This is what we provide.

According to the present invention, a garbage transfer means is provided in a garbage storage chamber having an input port opened at the upper part, and an opening is formed at the front end discharge port of the garbage storage chamber at the bottom thereof so as to be substantially flush with and continuous with the bottom of the storage chamber. In addition to installing garbage discharge hoppers, the inner width of the opening of the garbage discharge hoppers is
It has a configuration in which the width is larger than the inner width of the bottom of the exhaust port of the dust storage chamber.

(Function) According to the present invention, when the garbage stored in the storage chamber is moved toward the discharge port by the garbage transfer means, the garbage is moved while being compressed and solidified.
When the garbage reaches the garbage discharge hopper beyond the discharge port of the storage chamber, the compressed garbage expands because the width of the opening of the garbage discharge hopper is larger than the inner width of the bottom of the discharge port of the storage chamber. The compressed state is released and the material falls through the opening without causing any bridging.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a garbage storage chamber, which has an input port 2 at the top and a discharge port 3 at the front. The inclined walls 4 and 5 are formed so as to become tapered toward the bottom.

Reference numeral 6 denotes a garbage transfer means, which includes a transfer plate 7 that is slidable along a guide member 16 installed at the bottom of the garbage storage chamber 1, and a hydraulic cylinder arranged between the transfer plate 7 and the storage chamber 1. By moving the transfer plate 7 horizontally from the rear of the storage chamber 1 to the front discharge port 3 via the drive means 8, the garbage stored in the storage chamber 1 is passed through the discharge port 3. It can be supplied to a dust discharge hopper 9 which will be described later.

Reference numeral 9 denotes a garbage discharge hopper that is connected to the front end of the garbage storage chamber 1, and includes a front wall 10 and left and right side walls 11, 1.
2, the bottom part is formed into an opening that is continuous and substantially flush with the bottom surface of the storage chamber 1, and the front wall 1
The inner walls of the left and right side walls 11, 12 are formed into inclined walls 13, 14, 15 that taper downward.

The inner width A of the opening of the dust discharge hopper 9 is larger than the inner width B of the bottom of the discharge port 3 of the dust storage chamber 1.

The upper part of the garbage discharge hopper 9 is opened and connected to the input port 2 formed at the upper part of the garbage storage chamber 1, so that garbage can be directly dumped into the garbage discharge hopper 9 from the garbage collection vehicle. ing.

Next, the operation of the present invention will be described. Garbage collected by a garbage collection vehicle (not shown) is first dumped into the storage chamber 1 and is temporarily stored therein.

When the garbage thus stored is transferred to a container or the like, the transfer plate 7 is moved forward via the drive means 8.

As a result, the garbage pushed forward by the transfer plate 7 moves from the discharge port 3 of the storage chamber 1 to the opening of the garbage discharge hopper 9, and falls from the opening into a compactor or the like (not shown).

At this time, since the opening width A of the dust discharge hopper 9 is made larger than the bottom width B of the dust storage chamber 1, the compressed and solidified state of the dust is released by its expansion, and the dust is smoothly prevented from bridging. It is dropped onto the front of the compactor.

(Effects of the Invention) As explained above, in the storage and discharge device of the present invention, the front end discharge port of the garbage storage chamber is provided with a garbage discharge hopper that has an opening that is continuous and substantially flush with the bottom of the storage chamber. At the same time, the inside width of the opening of the garbage discharge hopper is made larger than the inside width of the bottom of the discharge port of the garbage storage chamber, which prevents the occurrence of a bridging phenomenon of garbage in the garbage discharge hopper part during the discharge and transfer of garbage, and eliminates bridging. Since there is no need to operate the device each time the transfer plate transfers the garbage, the discharge operation can be carried out efficiently.
