である。 As shown in Figure 1, A in the figure is a garbage collection vehicle.
A tank body 1 is installed at the bottom of the tailgate to store wastewater discharged from inside the tailgate. As shown in FIGS. 2 to 5, this tank body has a drain port 2 on one side, and this drain port 2 is provided with a lidding device that closes the tank watertightly from the outside. This lidding device has a fixing bracket 3 and a tightening member 4 on the left and right sides with the drain port 2 in between, one end 5a of a support arm 5 is pivotally supported on the fixing bracket 3, and the other end 5b is supported on the fixing bracket 3. A lid plate 6 is configured to be releasably engaged with the tightening member 4, and is provided at the longitudinal center of the support arm 5 to cover the drain port 2 when the support arm is in the tightened state. is provided.
The support arm 5 includes a pivot side arm 5 which is a channel member having a U-shaped cross section and whose one end 51a is pivoted to the fixed bracket 3 via a pin 31.
1, and one end 5 at the other end 51b of the pivot side arm 51.
A hanging side arm 52 is made of a channel member having a U-shaped cross section and whose midway end on the 2a side is pivotally supported via a pin 7.
The locking side arm 52 has a structure in which the locking side arm 52 is configured such that the free end on the other end 52b side is hooked to the tightening member 4. Along with being there,
The inner surface of the connection end that faces the pivot side arm 51 from the outside is cut out in a tapered shape so that it can freely rotate in the arm rotation direction (the direction opposite to the broken line arrow). Also,
In the figure, reference numeral 3 denotes an adjustment bolt screwed from the outside into one end 52a of the hanging side arm 52 located between the pivot point a of the pivot side arm 51 and the axis b of the hanging side arm 52. are screwed together toward the pivot side arm 51, and by adjusting the forward and reverse rotation, the latching side arm 52 is rotated in the arm rotation direction, and the support arm 5 relative to the tightening member 4 is rotated. It is now possible to adjust the tightening allowance. Further, reference numeral 9 in the figure is a bracket coaxially supported by a pin 7 that connects both arms 51 and 52, and the lid plate 6 is fixed to this bracket 9 so that it can swing freely. Furthermore, numeral 10 in the figure is a gasket attached to the corresponding surface of the cover plate 6 on the drain port 2 side.

のである。 Therefore, according to the above-mentioned configuration according to this invention, when the cover plate is closed to the drain port of the tank body by the rotation operation by opening one side of the support arm,
The lid plate is coaxially and pivotably supported by a pivot connecting portion between a pivot side arm and a hook side arm that constitute a support arm, and a hook whose free end is hooked to a tightening member. The side arm can be rotated in the direction of arm rotation (opening/closing direction of the cover plate) using an adjustment bolt screwed from the outside, so the cover plate can always be adjusted from the perpendicular direction to the opening surface of the drain. The packing contacts with an even pressing force, and no local pressure is applied to the packing corresponding to the edge of the pivot end of the support arm, making it possible to maintain a uniform tightness over the entire packing. Not only can the durability be improved, and the tightness can be easily adjusted according to the decrease in the elasticity of the packing, the dimensions of the cover plate can also be freely adjusted according to the opening size of the drain. It is also possible to expect an improvement in cleaning work efficiency due to the enlargement of the frontage size, and it is also possible to achieve effects such as making the entire lid closing mechanism thinner and more compact.
