Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sewage lid opening / closing device for a sewage tank that stores sewage discharged from dust in a garbage truck.

[0002]

[Prior Art]

 Conventionally, a waste water receiving device for a refuse collecting vehicle is provided with a waste water tank at the bottom of a dust throwing box, and a discharge port is provided at the side of the waste water tank, as seen in the one disclosed in Japanese Patent Publication No. 60-10961. In addition to being formed, a sewage lid for opening and closing the discharge port is provided so as to be openable and closable, and the sewage lid can be locked and released by operating a lock lever arranged at the rear part of the sewage tank.

When the dust in the dust storage box is discharged into the pit formed on the ground, the rear part of the dust collection vehicle (dust input box portion) is arranged above the pit, and then the lock lever is operated. The waste water lid was opened to discharge the waste water, and after the dust throwing box was tilted upward, the waste plate was moved to the rear to discharge the dust.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional one, the lock lever is arranged at the rear part of the dirty water tank, and therefore the operator has to lean over the pit and operate the lock lever, and the operator accidentally falls into the pit. There was a risk that it would end up, and it was extremely dangerous.

[0005]

[Means for Solving the Problems]

 The waste water lid opening / closing device of the waste water tank in the dust collecting vehicle of the present invention has a dust throwing box provided with a dust loading device connected to the rear opening of the dust storing box mounted on the vehicle frame in a tiltable manner. In a dust collection vehicle provided with a wastewater tank for storing wastewater discharged from dust at the bottom of the throw-in box, the discharge port formed on the side of the wastewater tank can be opened and closed by a wastewater lid. The sewage lid is provided with a hinge part on the front side of the sewage tank so as to be opened from the rear side. Furthermore, the hinge portion of the lock lever of the lashing device for lashing the sewage lid is the sewage lid. The lock lever is disposed on the rear side of the lock lever and the grip portion of the lock lever is disposed on the front side.

[0006]

[Action]

 The sewage lid is configured to open from the rear around the hinge part on the front side of the sewage tank, and the hinge part of the lock lever that locks the sewage lid is arranged on the rear side of the sewage cover and locked. By arranging the lever gripping member in the front, when draining sewage from the sewage tank together with dust into the pit formed on the ground, the operator rotates the lock lever from the front to secure the lashing device. Release the shackles and open the sewage lid.

【Example】

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

FIG. 1 shows a rear portion of a garbage truck according to the present invention.

In FIG. 1, reference numeral 1 denotes a dust storage box mounted on a vehicle frame of a dust collection vehicle. At the rear opening of the dust storage box 1, a dust input box 2 having an open front is provided with a pivot 3. It is connected so that it can be tilted. Further, a dust loading device (not shown) is installed in the dust throwing box 2, and the dust throwing device is used to feed the dust thrown from the throwing port provided at the lower rear portion of the dust throwing box 2. It is configured to be pushed in.

Reference numeral 10 denotes a dirty water tank 10 provided at the bottom of the dust throwing box 2, which is configured to store dirty water discharged from the dust when the dust is loaded.

A discharge port 11 (see FIG. 3) for discharging the waste water stored in the waste water tank 10 is formed on a side portion of the waste water tank 10. The discharge port 11 is shown in FIGS. The sewage lid 20 shown is configured to be openable and closable.

The sewage lid opening / closing device for opening and closing the sewage lid 20 will be described below.

The sewage lid opening / closing device is composed of an opening / closing arm 30 connected to the center of the sewage lid 20 via a bracket 31, and a lashing device 40 for staking the sewage lid 20 in a closed state. There is.

The opening / closing arm 30 is horizontally arranged along the side portion of the dirty water tank 10, and is configured to be rotatable around a hinge portion 32 provided on the front side of the dirty water tank 10. As a result, the sewage lid 20 is configured to open and close from the rear.

The lashing device 40 includes a lock lever 41 provided on the opening / closing arm 30 and a lashing pin 33 provided at the tip of the opening / closing arm 30 by the urging force of the lock lever 41. And a pressing member 48 that presses the closed side.

The lock lever 41 has a gripping member 43 whose base end is pivotally supported by a hinge 42 on the rear side of the opening / closing arm 30, and a slide member slidably provided in the middle of the gripping member 43. Since it is composed of a U-shaped fastening arm 46 whose both ends are pivotally supported by the member 45, it is fastened by a spring 47 interposed between the sliding member 45 and the tip of the gripping member 43. The arm 46 is always urged in the arrow P direction in FIGS.

The tip of the gripping member 43 is formed in a gripping portion 43a that is gripped by an operator when opening / closing the dirty water lid 20, which facilitates the opening / closing operation from the front.

A base end of the pressing member 48 is pivotally supported on a side rear side of the dirty water tank 10 via a bracket 48 a, and a tip end thereof is an engaging portion with the securing arm 46. There is. A locking member 49 that locks to the securing pin 33 of the opening / closing arm 30 is fixed to the tip of the pressing member 48.

When discharging the dust stored in the dust storage box 1 into the pit A as shown in FIG. 1, the rear part of the dust collection vehicle (the portion of the dust input box 2) is located above the pit A. After the placement, the lock lever 41 is operated to open the dirty water lid 20 to discharge the dirty water, and the dust throwing box 2 is tilted upward, and then the discharging plate provided in the dust storing box is moved backward. By doing so, the dust is discharged.

To open the dirty water lid 20 by operating the lock lever 41, an operator holds the grip portion 43a of the lock lever 41 from the front and rotationally operates the lock lever 41 to lock the fastening device 40. It is done by releasing. As a result, the worker can safely open the sewage lid 20 without jumping over the pit A.

[0021]

[Effect of the device]

 As described above, according to the sewage lid opening / closing device of the present invention, when the sewage in the sewage tank is discharged together with the dust into the pit formed on the ground, the operator rotates the rock lever from the front. Since the sewage lid can be opened by releasing the staking device to release the sewage lid, the operator can open the sewage lid without jumping over the pit, and the sewage lid can be opened easily and safely. You can
