Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sewage storage device in a dust-pushing device for storing sewage discharged during dust-pushing.

As shown in FIG. 6, the conventional sewage storage device in the dust removal device includes a sewage tank 03 below the bottom plate 02 of the push container 01, and a sewage hole 04 in the bottom plate 02 to drain the sewage inside the push container 01. The wastewater is introduced into the wastewater tank 03 through the wastewater hole 04 and stored therein. Further, the sewage stored in the sewage tank 03 is discharged by opening a drain port 05 formed in the side surface of the sewage tank 03.

By the way, in the above structure, since the sewage hole 04 communicating with the sewage tank 03 is bored in the bottom plate 02 of the pushing container, the dust is strongly pressed against the bottom plate 02 when the pushing plate operates to push the dirt. The sewage hole 04 is closed by the pressed dust. Therefore, the sewage in the container 01 is transferred to the sewage tank 04.
Problems arise that are difficult to guide within.

Moreover, since the dirt is caught in the sewage hole 04 when the dirt is pushed in, the problem of worsening the pushing effect arises.
Furthermore, when cleaning the inside of the dust container 01, the cleaning water inside the container 01 first enters the sewage tank 04 and is then discharged from the drain port 05, which worsens the flow of the cleaning water and There is also the problem that the discharge of small particles becomes difficult.

The present invention is intended to solve the above problems, and embodiments will be described below with reference to the drawings.

1 indicates a dust pushing device, and this dust pushing device 1
consists of a push-in container 3 connected to the rear end opening of the dust container 2, and a push-in plate 4 having approximately the same width as the width of the push-in container 3 and installed inside the push-in container 3. 3 has a bottom plate 5 and both side walls 6, 6, and has an extrusion port 7 communicating with the inside of the container 2 at the front and an input port 8 at the rear. The pushing plate 4
is actuated by a hydraulic cylinder (not shown) as appropriate;
By moving its tip along the bottom plate 5 of the pushing container 3, the pushing plate 4 can push the debris in the pushing container 3 into the container 2, and after the pushing is completed, it can be turned over. You can move to the pushing start position again.

Reference numeral 9 denotes a sewage tank provided below the bottom plate 5 of the push-in container 3, and this sewage tank 9 extends between both side walls 6, 6 of the push-in container 3.

Upper drain ports 10, 10 that open into the push container 3 and lower drain ports 11, 11 that open into the sewage tank 9 are provided on both side walls 6, 6 of the push container 3 to which the bottom plate 5 is attached, respectively. The lower drainage ports 11, 11 are extremely larger than the upper drainage ports 10, 10. Thus, the upper drain ports 10, 10 can directly discharge the sewage and washing water in the push-in container 3 to the outside of the container, and the lower drain ports 11, 11 can drain the sewage stored in the sewage tank 9 as will be described later. can be discharged outside the container.

12, 12 are sewage lids that are provided on both side walls 6, 6, respectively, and can hermetically close the upper drain ports 10, 10 and the lower drain ports 11, 11 at the same time;
These sewage lids 12, 12 each drain port 1 on the left and right.
0, 11, 10, 11 are closed, the sewage lids 12, 12 communicate through gaps 13, 13 formed by the inner surfaces and the side walls 6, 6, and the sewage in the push-in container 3 flows through the gaps. 13, 13, and is guided into the wastewater tank 9 and accommodated therein.

Since the sewage lids 12 and 12 have the same structure,
To explain one of them with reference to Figure 3, the sewage lid 1
2 is attached to the center of the support arm 14, one end of this support arm 14 is rotatably supported 15 by an appropriate member, and the other end of the support arm 14 is provided with an appropriate tightening device 16. Tightening device 16
By tightening, the sewage lid 12 seals the sewage holes 10, 11, and by releasing the tightening device 16, the sewage lid 12 is rotated around the shaft support 15, thereby opening the drain ports 10, 11. be able to.

The present invention has the above-described configuration, and the dust thrown into the push-in container 3 through the input port 8 slides on the bottom plate 5 by the operation of the push-in plate 4 and is accommodated in the dust container 2.

During the pushing operation, the dust is compressed and pushed between the pushing plate 4 and the bottom plate 5, so at this time, the sewage drips onto the bottom plate 5 and perforates the side walls 6, 6 of the pushing container 3. Upper drain outlet 10, 10
It flows out first, and then flows through the gaps 13, 13 between the sewage lids 12, 12 and the side walls 6, 6 to the lower drain 1.
1 and 11, and thereby the wastewater is stored in the wastewater tank 9. Next, after the dust collection work, in order to discharge the sewage in the sewage tank 9, the sewage lids 12, 1
If you open 2, the sewage in the sewage tank 9 will flow to the tank 9.
Can be discharged outside. Furthermore, when cleaning the inside of the dust container 2 and the push-in container 3, the washing water flows onto the bottom plate 5 of the push-in container 3 and directly flows out of the container 3 through the upper drainage ports 10, 10. The washing water flows out quickly, which makes the washing work smooth.

As described above, the present invention provides an upper drain opening into the push-in container and a lower drain opening into the sewage tank on the side wall of the push-in container to which the bottom plate is attached, and further provides the only sewage lid for opening and closing the upper and lower drain ports. By installing this, the sewage in the push-in container is stored in the sewage tank through the gap between the sewage lid and the side wall, and during washing, the washing water is directly discharged from the upper drain port to the outside of the container, so the washing water is It has a good flow and allows for smooth cleaning work.

In addition, since a hole that communicates with the sewage tank is drilled in the side wall, there is no need to close the drain port with dust when pushing in the waste water.Furthermore, since there is no drain port etc. drilled on the bottom plate, the dust on the bottom plate is not blocked. It has good sliding properties and allows for smooth pushing work.
