BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust storage facility for temporarily storing dust collected by a small garbage truck and transferring it to a large garbage truck.

[0002]

2. Description of the Related Art In a region where a refuse disposal facility is not nearby, the refuse must be transported over a long distance by a garbage truck. However, if garbage trucks frequently travel on the road, local residents along the road will complain. Therefore, a treatment method has been proposed in which a plurality of dust trucks for garbage trucks are temporarily stored in a place near the refuse trucks, and the waste trucks are transshipped to large trucks and transported to a refuse truck facility.

[0003]

However, in such a treatment method, it is absolutely necessary to have a facility for collectively storing the dust and dirt, and such a storage facility is capable of removing offensive odors and sewage from the outside from the viewpoint of pollution prevention. It is not allowed to leak to.

Further, in this storage facility, it is desired to thoroughly save space and cost because it is difficult to secure a site and cost.

The present invention has been proposed to meet such a requirement, and temporarily collects the dust collected by the dust collecting vehicle from the outside and stores it, so that the dust collecting vehicle is more hygienic than the conventional one. The purpose is to provide a compact dust storage facility that can be transshipped.

In order to achieve the above object, a dust storage facility according to the present invention has a vertical side wall having a discharge port at a lower end portion, and a lower end portion which is arranged so as to face the vertical side wall at the discharge port. A dust hopper having a continuous arc side wall, an extruding member arranged so as to be capable of reciprocating along an arc side wall inner surface of the dust hopper, an inlet connected to the discharge port at one end, and the other end. And a horizontal rotary drum provided with an outlet covered with an openable / closable lid plate.

Further, the dust storage facility according to the present invention includes a dust hopper having a vertical side wall having a discharge port at a lower end portion, and a circular arc side wall arranged to face the vertical side wall and having a lower end portion continuous with the discharge port. And a push-out member disposed so as to be capable of reciprocating along the inner surface of the arc side wall of the dust hopper.

[0008]

FIG. 1 shows an embodiment of the present invention.
It will be described with reference to FIG. This garbage storage facility 1
As shown in FIG. 1, a dust hopper 3 for inputting the dust 2, an extruding means 6 for pushing the dust 2 from the dust hopper 3,
The rotary drum 11 for horizontally storing the extruded dust 2 is provided.

As shown in FIGS. 2 and 3, the dust hopper 3 has a vertical side wall 4 and a circular arc side wall 5 which are arranged to face each other so that a charging port 3a for the dust 2 is formed at the upper end. A discharge port 4a for the dust 2 is formed at the lower end of the vertical side wall 4,
The lower end of the arc side wall 5 is continuous with the discharge port 4a.
The arc side wall 5 is formed of an arc of about a quarter around the support shaft P1.

The pushing means 6 includes two parallel arms 8 and 8 whose upper ends are rotatably attached to the left and right outer plates 7 and 7 of the dust hopper 3 by the support shafts P1 and P1. Cylinders 9, 9 and 2 for rotating the arms 8, 8
It is composed of a push member 10 that is bridged over the lower ends of the book arms 8, 8.

As shown in FIG. 2, each outer plate 7 has a storage space 7a for protecting the arm 8 and the cylinder 9. As shown in FIG. 3, a semi-circular cutout groove 7b for passing both ends of the pushing member 10 along the circular arc side wall 5 is formed in the lower part of the storage space 7a.

An upper end portion 9a of each cylinder 9 is rotatably attached to an upper portion of the outer plate 7 by a support shaft P2, and a rod end portion 9b thereof is attached to an intermediate portion of the arm 8 by a support shaft P3. There is.

As shown in FIG. 3, the extruding member 10 has a scooping surface 10a having a concave partial cylindrical surface on the side corresponding to the input port 3a, and a convex pressing surface 10b having a convex partial cylindrical surface on the side corresponding to the discharge port 4a. Is formed in.

On the other hand, as shown in FIG. 1, the rotary drum 11 has a horizontally-arranged cylindrical shape, and the dust 2 is provided at both front and rear ends thereof.
11a and 11b, respectively. Entrance 11
a is connected to the discharge port 4a of the dust hopper 3 and the outlet 11b
A lid plate 12 that can be opened and closed is provided in the. The rotary drum 11 can be rotated in the circumferential direction by a motor (not shown), and inside thereof, a spiral fin 11c for crushing or moving the dust 2 forward is formed as required. Although not shown, it also has a built-in filter that removes wastewater and the like generated during the crushing and compression processes.

Further, at the charging port 3a of the dust hopper 3,
A fall prevention gate 13 formed by arranging a plurality of grid bars 13a at equal intervals in parallel is arranged to be openable and closable in the horizontal direction. In addition, a touch sensor 14 that activates a drive source (not shown) of the fall prevention gate 13 when the rear wheel of the dust collection vehicle 15 comes into contact with the road surface is provided on the road surface near the input port 3a.

Next, the operation of the dust storage facility 1 will be described. When the rear wheel of the dust collection vehicle 15 is not in contact with the touch sensor 14, the input port 3a of the dust hopper 3 is covered by the fall prevention gate 13 to prevent the worker from falling into the dust hopper 3. .

Further, the inlet 11a of the rotary drum 11 is normally provided.
Is closed by the pressing surface 10b of the pushing member 10 and the outlet 11b is closed by the cover plate 12, so that the offensive odor inside the rotary drum 11 does not leak to the outside.

[0018] Then, a refuse collecting vehicle 15 loaded with the refuse 2
Moves to the inlet 3a and the rear wheel touches the touch sensor 14
When it contacts with, the fall prevention gate 13 slides above the rotary drum 11. In this state, the dust 2 is thrown from the plurality of dust trucks 15 instead of the throw-in port 3a of the dust hopper 3 and accumulated on the inner surface of the arc side wall 5.

When the dust 2 is accumulated on the inner surface of the circular arc side wall 5 to a certain height, the cylinders 9 and 9 are retracted so that the pushing member 10 is moved upward along the inner surface of the circular arc side wall 5 (A in FIG. 3).
Direction).

The dust 2 accumulated on the inner surface of the arc side wall 5 is
It is scooped up by the scooping surface 10a of the pushing member 10 moving along the inner surface of the circular arc side wall 5, climbs over the pushing member 10 and falls to the pressing surface 10b side (the discharge port 4a side). At this time, since the scooping surface 10a is formed as a concave cylindrical surface, the dust 2 easily crosses over the extruding member 10 and the load on the cylinder 9 is reduced, and the dust 2 serves as the charging port 3a of the dust hopper 3. It acts to prevent extrusion from the.

Next, the cylinders 9 and 9 are extended to rotationally move the pushing member 10 downward (direction B in FIG. 4) along the inner surface of the arcuate side wall 5 to remove the dust 2 falling in front of the pressing surface 10b. It pushes out from the discharge port 4a at the pressing surface 10b. On this occasion,
Since the pressing surface 10b of the convex partial cylindrical surface is formed downward, it serves to efficiently push out the dust 2 to the discharge port 4a so as not to escape above the pushing member 10. Moreover, since the dust 2 newly pushed out functions as a lid of the inlet 11a of the rotary drum 11, the offensive odor inside the rotary drum 11 does not leak to the outside.

The extruded dust 2 enters the rotary drum 11 through the inlet 11a of the rotary drum 11, is agitated by the fins 11c of the rotary drum 11 shown in FIG. 1, and is gradually compressed and stored.

When the dust 2 is stored in the rotary drum 11 to some extent, the lid plate 12 is opened to automatically discharge the dust 2 from the outlet 11b to the charging port 16a of the large dust truck 16. The refuse 2 transferred to the large garbage truck 16 is transported to a refuse disposal facility and placed in a refuse pit (not shown).

According to this dust storage facility 1, all the dust 2 that has been thrown into the dust hopper 3 from the small dust collection vehicle 15.
Of the pushing member 1 that reciprocates along the inner surface of the arc side wall 5.
With 0, extrusion into the rotary drum 11 can be performed quickly and reliably. Further, since the rotary drum 11 can crush and compress the dust 2 in a sealed state, there is no fear that a strange odor or the like leaks to the outside.

Therefore, although the entire apparatus is extremely compact, a plurality of small dust trucks 15 of the small refuse truck 15 are temporarily collected in a very hygienic and safe manner before being loaded into the large refuse truck 16. Can be stored.

FIG. 5 is a sectional side view of a modification of the refuse storage facility. In this dust storage facility 21, the input port 23a of the dust hopper 23 is formed in a funnel shape larger than the input port 3a of the dust hopper 3, and the rotary drum 11 is omitted and the discharge port 4a of the dust hopper 23 is provided. A large-sized garbage truck 16 has a loading port 16a connectable thereto.

Since the other constructions, functions and effects of the pushing means 6 and the like are almost the same as those of the above-mentioned refuse storage facility 1, the same reference numerals are given to simplify the illustration and description. According to this example, the entire configuration can be further downsized by the space where the rotary drum 11 is omitted.

[0028]

As described above, according to the dust storage facility of the present invention, since the pushing member is reciprocated along the inner surface of the arc side wall in the dust hopper, it is required outside the dust hopper. Space can be minimized, and all the dust on the arc side wall can be reliably pushed out to the discharge port of the dust hopper by this pushing member. In addition, dust is crushed and compressed in a rotary drum that is shielded from the outside and temporarily stored, so that foul odors and sewage do not leak to the outside before being loaded into a large garbage truck, which contributes to pollution prevention. Is.

[0029] In particular, it becomes possible to temporarily and safely store the dust of a plurality of small dust trucks with a rotating drum that is smaller than its volume in a sanitary manner, and secure a sufficient site for the dust relay facility. It is extremely convenient for local governments that cannot.
