Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a securing device for a garbage input box in a garbage collection vehicle.

(Prior Art) Generally, a garbage collection vehicle consists of a garbage storage box mounted on the vehicle body frame and a garbage input box that is tiltably connected to the rear opening of the garbage storage box. It is firmly tied to the garbage storage box. For example, as seen in Japanese Utility Model Publication No. 59-35448, a garbage storage box and a garbage input box are each provided with a hook and a U-shaped locking ring that can be engaged with the hook.

(Problem to be solved by the invention) By the way, since the above-mentioned locking ring is formed in a U-shape, in order to adjustably fix it to the bracket, it is necessary to attach it to each of the U-shaped legs. Two female threads are required for each male thread that is formed. Moreover, since a pair of locking rings are provided on the left and right, it is necessary to tighten or loosen a total of eight female threads in order to adjust the relative positional relationship with the hook, making adjustment cumbersome and There was a problem with the structure being complicated.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a lashing device for a garbage collection vehicle that has a simple structure and is easy to adjust.

(Means for Solving the Problems) The present invention provides a garbage storage system in which a garbage input box is tiltably connected to the rear end of the garbage storage box mounted on the vehicle body frame, and a garbage pushing device is provided inside the garbage input box. In the collection vehicle, a rotatable hook is provided on one side between the garbage input box and the garbage storage box, and a single hook is provided on the other side with a locking shaft that can be engaged with the hook at the tip. It has a structure in which a locking rod is slidably disposed and the locking rod is adjustable and fixed via a pair of nuts.

(Function) When assembling the garbage collection vehicle or adjusting the relative positional relationship of the garbage input box to the garbage storage box during use, the male threaded portion formed at the tip of a single locking rod on each left and right side is used. After loosening the pair of female threads, moving the locking rod back and forth while observing its positional relationship with the hook, tighten the pair of female threads at the appropriate position.

(Embodiment) Hereinafter, an embodiment of the present invention will be described with reference to the drawings.A garbage storage box 1 is mounted on the body frame of a garbage collection vehicle, and a pivot point is attached to the upper end of the rear opening 3 of this garbage storage box 1. A garbage disposal box 2 whose front side is open at 4 is connected so as to be tiltable rearward.

The base end of a lift cylinder 5 is connected to the rear end edges of both sides of the garbage storage box 1, and the lift cylinder 5
At the tip of the bracket 7 is fixed to the garbage input box 2.
One end of a sliding member 8 that is slidably inserted into the housing is connected to the housing. The other end of this sliding member 8 is connected via a connecting rod 9 to the base end of a hook 10 that is pivotally supported on the garbage storage box 2, and this hook 10 is fixedly installed at the bottom of the garbage storage box 1. The locking shaft 11 of the locking rod 11
It is designed to be connected to and disconnected from a. A stopper 12 that can abut against the bracket 7 is fixed to the upper part of the sliding member 8. When the lift cylinder 5 is slightly extended, this stopper 12 abuts against the bracket 7 and the subsequent lift cylinder 5 is moved. By extension, the garbage disposal box 2 can be tilted rearward around the pivot 4.

By the way, as shown in FIGS. 2 and 3, the locking rod 11 is slidably disposed on a guide member 13 having a rectangular insertion hole fixed to the lower part of the rear opening 3 of the garbage storage box 1. The rod body 11b is made up of a rod body 11b, and a locking shaft 11a is held by brackets fixed in a gate shape on both sides of the tip of the rod body 11b, and a male screw portion is formed at the base end of the rod body 11b. There is. A pair of nuts (female threads) 14 are screwed into the male threads while sandwiching the guide member 13 therebetween.

Next, the operation of the embodiment of the present invention will be explained. Normally, as shown in FIG.
The hook 10 is engaged with the locking shaft 11a via the locking shaft 11a, and the garbage input box 2 is firmly secured to the garbage storage box 1.

By the way, when it becomes necessary to adjust the relative positional relationship of the garbage input box 2 with respect to the garbage storage box 1 due to use, grasp the engagement relationship between the hook 10 and the locking shaft 11a and tighten the nut 14. By loosening or tightening, the rod main body 11b can be moved forward or backward, and the positional relationship between the two can be adjusted.

(Effect of the invention) As described above, according to the invention, by attaching the locking shaft that engages with the hook to the locking rod, it is only necessary to attach one locking rod to the left and right sides to the frame of the garbage storage box. This has the advantage that the number of adjustment points is reduced, making the adjustment work easier, and at the same time, the structure of the device can be simplified.
