Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a trash storage device installed in a residential area or the like for temporarily storing trash, and more particularly to a carry-out conveyor used to carry out the stored trash. Related to the mounting structure.

[Conventional technology]

Recently, in a residential area or a housing complex, garbage from ordinary households is temporarily stored in a garbage storage device installed in the residential area, and when the garbage storage device becomes full, the garbage is collected and collected. A method of collecting and transporting it to an incineration site or a burial site is adopted.

Conventionally, as a garbage storage device of this type, Japanese Patent Application No. 58-43
The one described in Japanese Patent No. 961 is known.

As shown in FIG. 8, this dust storage device is provided with a dust storage drum 42 for compressing and storing the dust, and a waste delivery for delivering the dust stored in the storage drum 42 to the dust collection vehicle 40. The conveyor 43 and the storage drum 42
It is configured with an outer case 44 that covers the outside of the entire device in order to prevent accidents involving the human body in the carry-out conveyor 43 or the carry-out conveyor 43. The dust carry-out conveyor 43 slides in the front-rear direction in the vicinity of the discharge port 45 of the storage drum 42. It is provided so as to be possible, and usually enters the lower side of the storage drum 42 and is housed inside the outer case 44.

In the above-mentioned dust storage device, dust is sequentially stored in the storage drum 42, and when the storage drum 42 is filled with dust, the carry-out conveyor 43 is pulled out from the outer case 44, and the front end of the carry-out conveyor 43 is stored. The rear end of the drum 42 is inserted into the dust receiving port 41 of the dust collecting vehicle 40 while facing the discharge port 45 of the drum 42, and the dust discharged from the discharge port 45 of the drum 42 is conveyed through the carry-out conveyor 43. It is designed to be sent to the garbage truck 40.

[Problems to be solved by the device]

In the structure described above, the mounting height of the carry-out conveyor 43 needs to be adjusted to the height of the dust receiving port 41 of the dust collecting vehicle having the highest vehicle height, and the dust storing drum 42 is set in accordance with the mounting height. It is necessary to set the support height of.

However, the height of the dust receiving port 41 of the dust collecting vehicle 40 having a high vehicle height is about 1 m, and the storage drum 4 is adjusted accordingly.
If the height of 2 is set, the position of the dust introduction port 46 of the drum 42 becomes high, and there is a drawback that the operability when throwing in dust is deteriorated.

For this reason, conventionally, as shown in FIG. 8, the loading stage 47 serving as a step is provided below the loading port 46 of the storage drum to cope with the height of the loading port 46. Since it is left outside the outer case 44, it becomes a playground for children and the like, and there is a danger that personal accidents such as a fall accident from the loading stage 47 are likely to occur frequently.

On the other hand, in order to lower the support height of the storage drum 42, the carry-out conveyor 43 is made to project to the rear side of the storage drum, and the storage drum 42 and the carry-out conveyor 43 are placed in the exterior case 4.
If the structure is covered with 4, the exterior case 44 needs to be greatly extended, so that the installation space of the device becomes significantly large. However, the garbage storage device installed in a residential area or the like is required to be stored in a space as small as possible, and such expansion of the installation space is a great obstacle to the facility.

Further, in Japanese Utility Model Publication No. 60-37365, there has been proposed a structure in which a lower end of a belt conveyor is attached to a loading port of a refuse collecting vehicle so as to be vertically movable, and dust is carried in by the belt conveyor. When the lower end of the carry-out conveyor 43 is rotatably attached to the discharge port 45 of the storage drum 42 when applied to the waste collection device shown in FIG. 8, the discharge port and the end of the conveyor do not overlap in the longitudinal direction. Therefore, there is a problem that the dust discharged from the discharge port 45 easily leaks from the rear end portion of the carry-out conveyor 43.

However, in order to prevent the dust from leaking out, if a chute or the like for guiding the dust to an intermediate position of the carry-out conveyor 43 is attached to the discharge port 45, the total length of the storage drum 42 becomes long and the installation space of the device is expanded. I have a problem to do.

The present invention has been made in view of the above problems, and the carry-out conveyor can be compactly housed inside the outer case, and the dust inlet of the storage drum can be set to an appropriate height regardless of the mounting position of the carry-out conveyor. It is intended to provide a garbage storage device.

[Means for Solving the Problems]

In order to solve the above problems, the present invention comprises a dust storage drum that stores dust by compression, and an outer case that covers the outside of the storage drum, and at the discharge port of the storage drum,
In a horizontal state, one end is provided with a dust discharge conveyor that enters the dust collection port of the dust collection vehicle, and the outer diameter of the storage drum discharge side is a tapered portion that reduces in diameter toward the discharge port. An intermediate part in the length direction is attached rotatably in the vertical direction with the vicinity of the discharge port as a fulcrum, and the end on the storage drum side of the carry-out conveyor is positioned below the taper part of the storage drum in a horizontal state. Under the tapered portion, a swinging base that is horizontally rotatable around the lower position of the discharge port is provided. The swinging platform supports the carry-out conveyor, and the discharge-side end of the exterior case is fixed. That is, it is formed in a size that covers the upright conveyer.

[Action]

In the above structure, since the carry-out conveyor is rotatable up and down, and only the end of the carry-out conveyor is allowed to enter below the taper portion of the storage drum, the entire carry-out conveyor can be pulled out below the storage drum. The supporting height of the storage drum can be set lower than that of the conventional structure, and the height of the charging port can be set at a position with good workability.

Moreover, since the conveyor is stored in the outer case in an upright state, the outer case does not need to be extended so that the apparatus can be made compact.

In addition, if the structure is such that the carry-out conveyor is supported by the rocking table,
When the refuse collecting vehicle approaches the carry-out conveyor in a tilted manner, the direction of the carry-out conveyor can be easily matched with the dust collecting car by rotating the rocking table.

In addition, a midway position in the length direction of the carry-out conveyor is made rotatable with respect to the discharge port, and the positions of the rotation fulcrum of the carry-out conveyor and the rotation fulcrum of the rocking platform are horizontal near the discharge port and below the discharge port. Since they are aligned in the same direction, it is possible to prevent spillage of dust carried out to the carry-out conveyor from the discharge port, and it is possible to stack the carry-out conveyor and the rocking platform below the taper part of the storage drum. The amount of the carry-out conveyor protruding from the storage drum can be reduced.
