Description

[Detailed description of the invention] This invention is a dump truck in which a diagonal plate is installed on the rear axle at the rear of the loading platform in order to properly distribute the load (sand, gravel, etc.) on the front and rear axles of the dump truck. It is related to packing boxes.

Conventionally, in a dump truck, when you want to load a load to the full allowable load of the coupler and rear wheels,
If it is possible to increase the load borne by the coupler, it is advantageous to load the load as close to the front of the vehicle as possible, so the load is loaded in the front of the cargo box.

However, since it is difficult to provide the rear wheels at the front due to the design of the vehicle, the rear wheels are provided at the rear of the vehicle. Therefore, the floor surface of the cargo box provided above the rear wheels extends to the rear of the wheels, and the floor surface behind the rear fan provided on the cargo box is exposed. Therefore, when a load is loaded onto a loading platform using a shovel loader or the like with the floor exposed, the load inevitably falls and accumulates on the floor behind the rear fan. If the vehicle is operated with this condition as it is, the cargo accumulated on the rear floor surface during driving will be undesirably scattered on the road due to vibrations of the vehicle. Therefore, it is possible to manually remove the sand, gravel, etc. that have fallen onto the floor behind the rear fan before operation, but this is extremely troublesome and requires a lot of effort.

This invention is a device that improves the above-mentioned drawbacks, and even if a loaded object falls onto the slanted plate, it will not fall onto the floor behind the rear fan, but will immediately fall to the ground, and will fall onto the floor behind the rear fan. The purpose is to prevent deposition.

The present invention provides a vehicle with a floor surface 11 located behind the rear surface of the rear fan 6 provided at the rear of the cargo box 5.
A loading box for a dump truck, characterized in that a slanted plate 10 is provided to cover the rear floor surface 11,
To explain in more detail based on one embodiment with reference to the drawings, as shown in FIG. 4, in a vehicle 2 having a floor surface 11 behind a rear fan 6, a pair of hinge brackets 12 are provided on the left and right sides of the upper part of a cargo box 5. The rear fan 6 is rotatably attached to the rear fan 6 with a hinge pin 7, and a diagonal plate 10 and a reinforcing plate 13 are provided on the side surfaces of the rear fan 6, which are inclined so as to have a triangular cross section. The vehicle 2 is connected to the coupler 3 by the tractor 1 as shown in FIG.
are rotatably connected.

Since the present invention is constructed as described above, when a load is loaded into the cargo box 5 using a shovel loader or the like as shown in FIG. It can be prevented from immediately sliding down on the slanted plate 10 and depositing on the floor surface 11. In addition, when unloading the cargo loaded in the cargo box 5, even if the cylinder 4 is actuated and the cargo box 5 is rotated and tilted around the shaft 9 of the dump bracket 8 as shown in FIG. Since the fan 6 is rotatable about the hinge pin 7, there is no resistance to discharging the loaded object, and the loaded object can be easily lowered.

Therefore, according to the present invention, it is possible to prevent the loaded items from falling onto the road from the floor surface while driving, and it is also possible to eliminate the manual work of removing the loaded items from the floor surface, which is practical in terms of safety and work. have an effect.
