Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wastewater storage tank for a garbage collection vehicle.

Conventionally, garbage collection vehicles have been known in which a discharge plate is slidably disposed in a garbage storage box mounted on the vehicle body frame, and in the case of such garbage collection vehicles, sewage leaked from the garbage is collected. In order to collect wastewater, a wastewater tank is installed further forward of the discharge plate in the most forward position.

In such a sewage tank, multiple openings are drilled into the floorboard of the garbage storage box to collect sewage, but the openings are blocked by waste that has gotten around to the front of the discharge plate, causing the sewage to drain. There was a problem that collection was not carried out smoothly, or the sewage in the sewage tank would spill out from the opening due to sudden starts, sudden stops, or rolling when making a right or left turn, staining the driver's cab.

The present invention has been made in view of the above points, and is designed to smoothly collect wastewater inside the garbage storage box and to prevent the collected wastewater from splashing out to the outside as much as possible so as not to contaminate the surrounding area. The present invention provides a sewage storage tank for a garbage collection vehicle.

Therefore, in the present invention, a garbage input box is tiltably connected to the rear opening of the garbage storage box mounted on the vehicle body frame, and a discharge plate that is slidable in the front and rear directions is provided inside the garbage storage box. In the garbage collection vehicle, a discharge port is opened across the width of the floor of the garbage storage box located on the back side of the discharge plate, a storage tank is fixed to the lower part of the discharge port, and a storage tank is fixed to the bottom of the discharge port. A structure in which a lid body having a groove formed in the width direction of the garbage storage box is fixed, and further, at least one end of the groove is opened to communicate with the storage tank, and a letter-shaped shielding plate is attached above the opening. It has the following.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In Fig. 1, the garbage storage box 1 mounted on the frame of a garbage collection vehicle has a hinge pin 2' at the rear upper end so that the garbage input box 2 can be raised and lowered. The rear part of the garbage storage box 1 is opened into the garbage input box 2 through an opening 3 thereof.

The garbage input box 2 has an input port 4 at its rear and a garbage storage chamber 5 at its lower part.

This garbage input box 2 houses a garbage pushing device A that pushes garbage into the garbage storage box 1. This device A consists of a telescopic cylinder 6, a hydraulic motor 7, a telescopic cylinder 6, a hydraulic It is composed of a push plate 9 and a rotary plate 8 connected to a motor 7.

A garbage discharge plate 10 is housed in the garbage storage box 1 so as to be able to slide back and forth.
The back surface of the is connected via a link mechanism 12 to a telescoping cylinder 11 pivotally supported at the front of the garbage storage box 1, and the discharge plate 10 slides back and forth within the trash storage box 1 by the expansion and contraction operation of the telescoping cylinder 11. I'm starting to be able to do it.

In FIG. 1, when the discharge plate 10 is fully contracted in front of the garbage storage box 1, as shown by the chain line,
A discharge port 13 is opened on the back side of the discharge plate 10 and extends completely across the floor width direction of the garbage storage box 1.
A storage tank 14 is fixed to the lower part of the discharge plate 13.

Furthermore, the discharge port 13 has a
A lid body 16 is fixed to the garbage storage box 1 in which a groove 15 forming an open channel is formed across the width direction of the garbage storage box 1 so as to cover the inside of the garbage storage box 1. At least one left and right end of the groove 15 formed in the lid body 16 has an opening 17 that communicates with the storage tank 14 . A cross-sectional shielding plate 18 is fixed to prevent inward splashing of wastewater into the wastewater.

The horizontal part of the shielding plate 18 is connected flush with the floorboard, and the vertical part is fixed so as to fill only the upper part of the groove 15 without blocking the flow of waste water.

Next, the operation of the embodiment of the present invention will be explained.
Now, as shown by the solid line in FIG. 1, the telescopic cylinder 11 is extended to move the discharge plate 10 near the rear opening end of the garbage storage box 1, and then the garbage pushing device A is activated to move the garbage into the garbage input box 2. The garbage is forced into the garbage storage box 1 through the opening 3. Then, the pushing pressure applied to the front surface of the discharge plate 10 is applied to the telescopic cylinder 11.
When the pressure becomes higher than the internal pressure, the discharge plate 10 gradually retreats, and the garbage storage box 1 can evenly store highly densely compressed garbage.

On the other hand, when discharging the garbage in the garbage storage box 1, if the garbage input box 2 is rotated upward around the hinge pin 2' and then the telescopic cylinder 11 is extended, the discharge plate 10 moves back and the garbage is removed. can be discharged.

By the way, in the above operation, the garbage is compressed to a high density in the garbage storage box 1, so the sewage extracted from the garbage enters the back side of the discharge plate 10, and then falls into the groove formed in the lid body 16. Further groove 15
It flows down through an opening 17 opened at one end and is stored in the storage tank 14.

The wastewater that has flown down and is stored in the storage tank 14 in this way is subject to inertia that tends to splash out through the opening 17 due to the sudden start, sudden stop, or rolling of the garbage collection vehicle when turning right or left. However, even if the wastewater travels along the inner wall of the storage tank 14 and reaches the opening 17, it collides with the shielding plate 18, and its horizontal part prevents it from splashing upward, while its vertical part prevents it from splashing inward. Since the projecting direction of the sewage water is changed downward, it does not splash out to the outside.

As described above, according to the present invention, even when sewage stored in a storage tank is splashed up due to the sudden start or stop of a garbage collection vehicle, the resulting sewage is splashed to the outside by colliding with the shielding plate. As a result, sewage does not adhere to the driver's cab of the garbage collection vehicle, and no foul odor is generated.
