Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a garbage storage device used for storing and transporting garbage.

[Conventional technology and its problems]

In recent years, the distance between residential areas and garbage disposal sites has become longer.
In the method of collecting garbage by making many garbage collection trucks reciprocate during that time, there is a problem that the collection efficiency decreases and causes traffic congestion and the like.

For this reason, the conventional collection method is to transfer the garbage collected by a garbage truck to a large relay vehicle, and then transport the garbage to a final treatment site by the relay vehicle.

However, in the collection method described above, conventional garbage trucks use a method of flipping up the tailgate of the rear door and dumping the garbage collection box to discharge garbage. If garbage is transferred directly from the garbage truck to the relay truck, there are problems such as the tailgate interfering with the garbage truck or the garbage truck's discharge position being lower than the reception truck's receiving position. Therefore, in order to transfer the garbage, it is necessary to discharge one load of garbage from the garbage truck and transport the garbage to the relay vehicle using a conveyor device or the like.

However, since a large space is required for the transfer site for transferring such garbage, it is difficult to secure such a location near a residential area, and the stench of garbage discharged from garbage trucks can cause problems in the surrounding area. It has the disadvantage of disturbing the environment.

On the other hand, in residential areas, housing complexes, etc., garbage storage devices are installed to temporarily store -111Q household garbage and collect it in garbage trucks when the garbage is full.

As shown in FIG. 10, this garbage storage device includes a garbage storage drum 41 having spiral blades 42 on its inner peripheral surface, and a garbage storage drum 41 mounted on a mount 4.
The storage drum 41 is rotatably supported on the storage drum 41, and has an input port 44 on the rear surface, and an output port 45 that can be opened and closed with a door 46 on the front surface.
A garbage conveyor 47 is attached so as to be slidable back and forth.

In the above device, when garbage is inputted from the input port 44,
The storage drum 41 is rotated, and the dust is compressed and stored on the front surface of the drum by the feeding action of the spiral blade 42. and,
When the garbage is full, the unloading conveyor 47 is inserted into the garbage truck 48 and the storage drum 41 is removed.
is rotated to carry out the garbage from the discharge port 45.

In this storage device, there is no tailgate at the discharge port 45,
Moreover, since the storage drum 41 is not dumped, it is possible to carry out the garbage directly from the discharge port to a large relay vehicle. The height of the pedestal 43 is set to match the garbage reception port of the garbage truck with the highest vehicle height, so when loaded on a moving vehicle, the center of gravity becomes extremely high, making it difficult to transport by vehicle. There's a problem.

Also, instead of transferring the garbage to the relay truck, the storage drum 41
When discharging garbage directly to a garbage disposal site or the like, the method of discharging the garbage from the discharge port 45 using the feed of the spiral blade 42 has the disadvantage that the discharge speed is slower and the discharge efficiency is lower than that of the dump method.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a garbage storage device that enables transportation by a traveling vehicle, transfer of garbage to a large relay vehicle, and discharge of garbage using a dumping method.

[Means to solve the problem]

In order to solve the above problems, the present invention rotatably supports a garbage storage drum equipped with spiral blades on the inner circumferential surface on a pedestal, provides an input port on the rear surface of the storage drum, and opens and closes it with a door on the front surface. In a garbage storage device equipped with a discharge port, the rear surface of the storage drum is used as an opening/closing door that pivots vertically around the upper end as a fulcrum, and the height of the pedestal can be changed.

[Effect]

The storage device with the above structure, with the height of the pedestal lowered,
It is loaded onto a moving vehicle and transported. When transferring trash to a relay vehicle, the storage device is removed from the vehicle, the height of the pedestal is raised, and the trash is transported to the relay vehicle through the discharge port on the front of the storage drum.

On the other hand, when the garbage is directly discharged from the storage drum while loaded on a traveling vehicle, the rear opening/closing door is opened and the storage device is dumped onto the traveling vehicle and discharged.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in FIGS. 1 and 2, the garbage storage device A of the embodiment includes a garbage storage drum 1, a pedestal 2 that supports the storage drum 1, and a carry-out conveyor 3 that carries out the garbage in the storage drum 1. It consists of

The storage drum 1 is a hollow drum with openings at both front and rear ends, and the opening at the rear end serves as a discharge port 4. This storage drum 1 has an outer circumferential surface tapered so that the diameter decreases from the middle in the length direction toward the front side, and is rotatably supported by a large ball bearing 5 and a roller 6 provided on a pedestal 2.

Further, a gear ring 7 is attached to the circumferential surface of the storage drum 1, and a gear connected to an electric motor 8 meshes with the gear ring 7. This electric motor has an external t
The power connector connected to B is connected.

A plurality of scraping blades 10 are attached to the inner circumferential surface of the storage drum 1 at regular intervals in the circumferential direction along the rear opening 9, and a spiral shaped A feed blade 11 is attached.

The rear opening 9 of the storage drum 1 is covered by an opening/closing door 13 that rotates in the vertical direction about a pin 12 at the upper end.
A hook 14 for lashing the vehicle and an air cylinder 15 for rotating the hook 14 are attached.

A garbage inlet 16 is formed in the center of the lower part of the opening/closing door 13, and a lockable lid plate 17 is attached to the inlet 16. This cover plate 17 is rotatably attached to the lower end as a fulcrum, and can be used as a garbage platform when it is tilted forward.

Further, on the back side of the opening/closing door 13, a dust guide plate 18 is attached which enters inside the storage drum 1 when the opening/closing door closes the rear opening S, and the guide plate 18 and the scraping blade 10 of the storage drum 1 As a result, the garbage inputted from the input port 16 is sent to the back side of the drum.

A lid 19 for opening and closing the discharge port 4 at the front end of the storage drum 1 is attached, and an air cylinder 21 for rotating the lid 19 is connected to an arm 20 that supports the lid 19.

Moreover, the conveyor 3 for carrying out disposed below the discharge port 4 is slidably attached to a rail 23 extending in the front-rear direction via a rocking table 22 that swings in the horizontal direction.

When this conveyor 3 is pulled out forward, its tip protrudes from the discharge port 4 and swings together with the swing table 22.
When pushed backward, its tip is stored under the storage drum 1.

The reason why the unloading conveyor 3 is made swingable in this way is that when the relay vehicle approaches the discharge port 4 at an angle, the rocking table 22 is swung to change the orientation of the unloading conveyor 3 to the receiver of the relay vehicle. This is because by aligning the conveyor 3 with the entrance, the conveyor 3 can be reliably inserted into the receiving opening.

On the other hand, as shown in FIGS. 4 and 5, legs 25 are foldably attached to the four corners of the lower surface of the pedestal 2 via pins 24, and a shaft 26 connects the two legs 25 on the front and rear sides. .2
6 are connected to pins 28, 28, which are respectively connected to air cylinders 27, 27.

This bin 28.28 is connected to the placket 29.28 on the underside of the pedestal 2.
It is movably fitted into a long hole 30.30 in the longitudinal direction provided in 2S, and when the air cylinder 27.27 is expanded or contracted,
The bins 28, 28 move back and forth, and each 125 is raised or folded.

Furthermore, each leg 25 is provided with a cylinder chamber (as shown) inside, and by letting air in and out of the cylinder chamber, the foot seat 31 expands and contracts to change its length. Here, an introduction pipe (when shown) connected to an external air source is connected to the cylinder chamber 1825, the air cylinder 27.27 for folding the legs, and the air cylinder 15.21 described above.

Further, at the front end of the pedestal 2, there is a dump cylinder 34, which will be described later.
A hole 32 for connecting a piston pin is provided,
A hole 33 through which a support shaft 35 is rotatably inserted is provided at the rear end of the pedestal 2.

The garbage storage device A of the embodiment has the above structure,
When installing in a vacant lot such as a residential area, as shown in FIG. 1, the legs 25 of the pedestal 2 are erected, and the opening/closing door 13 of the storage drum 1 is secured to the rear opening 9 with the hook 14. In this case, the length of the legs 25 is adjusted so that the position of the input port 16 matches the posture of a person to throw in the garbage.

In addition, when loading and transporting on a traveling vehicle, as shown in FIGS. 6 and 7, the wI525 is folded and placed on the loading platform of the traveling vehicle B, and the dump cylinder 34 is inserted into the hole 32 at the front end of the pedestal 2. A support shaft 35 attached to the vehicle B is connected to the hole 33 at the rear end.

In order to store garbage in both of the above usage conditions, the garbage is thrown into the storage drum 1 through the input port 16, and the storage drum is rotated by the electric motor 8.

As a result, the garbage is removed between the scraping blade 10 and the garbage guide plate 1.
It is sent to the back side of the storage drum 1 by the guide 8, and then sent to the back side of the drum by the action of the sending blade 11. Then, when garbage is sequentially thrown in later, the garbage is pressed against the lid 19 that closes the discharge port 4 and is stored inside the drum 1 in a compressed state.

Next, if you want to transfer the stored garbage to a large relay truck,
As shown in FIG. 8, the storage device A is installed on the ground with the legs 25 upright, and the length of the legs 25 is adjusted so that the conveyor B for carrying out is slightly higher than the position of the reception port 36 of the broadcast vehicle C. to 1
j1 verse.

In this state, the unloading conveyor 3 that has been pulled out is inserted into the receiving bay 36 of the relay vehicle C, the lid 19 is rotated to open the discharge port 4 of the storage drum, and the storage drum 1 is rotated by the electric motor 8. At the same time, the conveyor 3 for carrying out is operated. Thereby, the garbage is sent out from the discharge port 4 onto the carrying-out conveyor 3 by the action of the feeding blade 11, and is sent into the inside of the relay vehicle C by the carrying-out conveyor 3.

On the other hand, in order to discharge the garbage with the storage device loaded on the traveling vehicle, remove the hook 14, untie the opening/closing door 13, and extend the dump cylinder 34 to store the garbage as shown in FIG. Dump device A. As a result, the opening/closing door 13 rotates to open the rear opening 9 of the storage drum 1, and the garbage is discharged from the rear opening 9.

In the above embodiment, the height of the pedestal 2 is changed by the two structures of extending and contracting the legs 25 and folding the 1j125, but it is also possible to change the height of the pedestal by only one structure. good.

Furthermore, when discharging the dump truck, the opening/closing door 13 is naturally opened by gravity acting on itself, but it may be forcibly opened/closed by a cylinder or the like.

〔Effect of the invention〕

As described above, this invention makes it possible to change the height of the pedestal that supports the storage drum, making it possible to load it onto a traveling vehicle and drive it, and also to adjust the height of the discharge position. This has the effect of making it easier to transfer trash to the relay vehicle.

In addition, since the rear surface of the storage drum is provided with an opening/closing door, the garbage can be discharged by dumping the storage device, and there is an advantage that garbage can be efficiently discharged.
