Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a front-loading and discharge-type garbage storage device.

[Conventional technology]

Recently, garbage storage devices have been used in garbage processing facilities for residential buildings and other mid-to-high-rise buildings to temporarily store garbage and transfer it to garbage collection trucks. This garbage storage device has a garbage storage drum, which is rotated in the loading direction when loading garbage, and rotated in the same direction when discharging garbage, and the drum is rotated in the same direction to collect garbage toward the discharge port located on the opposite side of the input port. It is now possible to send

[Problem to be solved by the invention]

In this type of conventional garbage storage device, the garbage inlet and outlet are separate, with the inlet being located at a higher position and the outlet being located at a lower position. Therefore, for charging, it is necessary to provide a step, a lifting device, etc. up to the high charging port. In other words, the part of the garbage collection vehicle that receives garbage from the discharge port via a belt conveyor, etc. is relatively high, so in order to make the discharge port a height that matches that height, the installation height of the entire device has to be high, resulting in My mouth goes up even higher. Therefore, the equipment cost of the entire device is also high.

In view of the above points, the present invention can serve as both the input port and the discharge port, so the height of the entire device can be reduced, the structure is simple, and there is no need for a step for loading or a lifting device. The purpose of the present invention is to obtain a front charging and discharging type garbage storage device that is generally inexpensive.

[Means to solve the problem]

The front loading and discharging type garbage storage device of the present invention includes a horizontal garbage storage drum that is rotatably supported in the loading direction and the opposite discharge direction, and a drive that rotates this drum in the loading direction and the discharging direction. When the device and the drum are rotated in the loading direction, the garbage is sent from the entrance/exit side of the drum toward the back side of the drum, and when the drum is rotated in the discharge direction, the garbage is sent from the back side of the drum toward the entrance/exit side. It has a feeding vane provided in the drum, and a loading/discharging structure which is rotatable relative to the drum but supported so as to rotate together with the drum by friction within the opening on the entrance/exit side of the drum. This structure is equipped with an input/discharge sheet that opens into the drum and extends in a direction oblique to the drum rotation axis from a garbage input/discharge opening provided on the front surface of the drum. A loading stopper that comes into contact with a loading and unloading structure that rotates in the same direction when rotated in the same direction, and stops the rotation at a rotational position where the opening in the drum of the loading and unloading chute is at its lowest position, and the drum. When the loading/unloading chute is rotated in the unloading direction, the unloading stopper comes into contact with the loading/unloading structure rotated in the same direction and stops the rotation at the rotational position where the opening in the drum of the loading/unloading chute is at its highest. It is provided in the locus of rotation of the loading and discharging structure.

[Effect]

When the garbage storage drum is rotated in the loading direction, the loading/discharging structure also rotates in the same direction and comes into contact with the input stopper and stops. When the loading and unloading structure is stopped, it automatically assumes the rotational position where the opening in the drum of the loading and unloading chute is at its lowest point, so that when garbage is thrown into the loading and unloading chute, it slides down inside the chute. Fall into the drum. As the garbage accumulates due to loading, when the drum is rotated in the loading direction, the garbage is sent toward the back of the drum by the blades.

When dust accumulates in the drum and needs to be discharged, the drum is rotated in the discharge direction. As a result, the loading/discharging structure also rotates in the discharging direction and comes into contact with the discharging stopper and stops. The stopped loading/discharging structure automatically assumes the rotational position where the outer opening of the loading/discharging chute is at its lowest point, so as the drum rotates in the discharging direction, the dust inside is stirred up and removed from the loading/discharging chute. The waste is sent to the opening in the drum, and from there it slides down the input/discharge chute and is thrown into the sump of the garbage truck.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In Figure 1, a garbage storage drum 2 is placed on an underframe 1.
is provided rotatably around the rotation axis 2a. The drum 2 is supported by a bearing 5 of a support frame 4 via a shaft 3 on its back side, and supported by a pair of support rollers 6 on its entrance/exit side as shown in FIG. There is. The drum 2 is connected to a sprocket 7, a chain 8,
It is rotated via the sprocket 9 in the discharge direction A (FIG. 2) and its opposite loading direction B (FIG. 4).

On the inner surface of the drum 2, there are spiral blades 10 for transporting garbage.
is provided. When the drum 2 is rotated in the loading direction B, the feed blade 10 sends the garbage to the right in FIG. send. A helical blade 12 for scooping up dust is provided on the entrance/exit side of the drum 2, that is, on the left end side in FIG.

A loading/discharging structure 13 is rotatably provided within the opening of the drum 2 on the entrance/exit side. The drum 2 has a bearing 11 at its entrance/exit side end, and a structure 13 is supported by this bearing. This structure 1
3 has a generally cylindrical main body 13a, an outer end wall 13b, and an inner partition plate 13c, and an input/discharge chute 14 is provided between the end wall 13b and the partition plate 13c. It is being This chute has at its outer end a garbage input/discharge opening 14a located at the level of the rotation axis 2a, and its inner end 14d is open to the inside of the drum 2. This shot 1
4 extends in a direction oblique to the rotational axis 2a of the drum, so that the inner end 14b reaches near the inner circumferential wall of the drum. The opening 14a is normally closed by a lid 16. The lid 16 has a charging lid 16a that can be opened and closed, and is slidable along a guide rail 17.

A frame 1 is installed around the loading and unloading structure 13.
8 is fixedly installed, and a pair of stoppers 19 and 20 are provided facing each other on this frame as shown in FIG. The stopper 19 is a discharge stopper, and the stopper 20 is a charge stopper. On the other hand, a protrusion 21 is provided on the loading/discharging structure 13 in a protruding manner.

Next, the effect will be explained.

The state in which garbage is loaded into the drum 2 is as shown in FIGS. 3 and 4. That is, when the drum 2 is rotated in the loading direction B by the motor M after the garbage has been discharged, the structure 13 also rotates in the same direction due to the friction caused by the seal (not shown) between the drum and the structure 13. , the protrusion 21 on the outer surface hits the loading stopper 20, and the structure 13 stops. On the other hand, drum 2 also slightly overruns and is stopped. The position of the protrusion 21 is such that the chute 14 is in the third position when it is stopped by the stopper 20.
As shown in the figure, the opening 14b is set at the lowest position. Therefore, as long as the drum 2 is rotated in the loading direction B by the motor M, the loading and unloading structure 13 automatically assumes the position shown in FIG. Therefore, when the inlet 14a of the lid 16 is opened in this state and the garbage is thrown into the chute 14, the garbage slides down the inside of the chute and falls into the drum 2.
At this time, since the input port is not at a high position on the drum,
There is no need to use stages or lifting devices for loading. When the drum 2 is rotated in the loading direction B from time to time as the garbage accumulates due to loading, the garbage is removed from the blade 1.
0, it is sent to the back of the drum one by one. At this time, the direction of the chute 14 of the structure 13 does not change due to the rotation of the drum.

When the drum is full of dust and must be discharged, the drum is rotated in the discharge direction A in FIG. 2 by the motor M. As a result, the structure 13 is rotated in the same direction, and its protrusion 21 is also moved in the same direction, and after having rotated approximately 180 DEG, it comes into contact with the stopper 19 as shown in FIG. This results in structure 1
3 stops rotating. At this time, the orientation of the chute 14 is as shown in FIG.
It is likely to become higher. On the other hand, after the rotation of the structure 13 stops, the drum 2 also slightly overruns and is stopped. After connecting the sump S of the garbage truck and opening the lid 16, when the drum 2 is rotated again in the discharge direction, the dust inside the drum 2 is scraped up to the opening 14b at a high position by the action of the scraping blade 12 and sent there. It is dropped through the opening 14a into the tailgate sump S (FIG. 1) of the garbage truck.
The opening 14a is at the same height as when garbage is thrown in, so it is not too low, and there is no need to install the entire device high to match the height of the tailgate sump S.

〔Effect of the invention〕

As described above with respect to the embodiments, according to the present invention, garbage can be input and discharged through a single input/discharge port, and the chute connected to this input/discharge port is used for input or discharge. Since the inclination can be set to a suitable angle, charging and discharging operations can be carried out without any trouble, and the problem of the prior art that the charging port is too high can be solved, and an inexpensive garbage storage device can be provided.
