[0002]

2. Description of the Related Art Dump trucks used for civil engineering work are
The rear cargo bed can be moved up and down by a cylinder drive. The cargo on such platforms is mainly sand,
When unloading gravel, garbage, etc., the front side is raised to incline the platform, and the load can be automatically unloaded to the rear by using its own weight.

FIG. 14 is a conceptual diagram showing a conventional method for harvesting tea and a method for transporting harvested raw tea leaves.
A tea leaf (raw tea leaf) 101 is cut from a tea tree 100 by scissors and packed in a bag 102 at the same time, and the raw tea leaf 101 is transferred from this bag 102 to a basket 103, and the basket 103 is loaded on a truck 104 to collect cargo. Carry to 105. Collection point 10
In No. 5, after the raw tea leaves 101 are taken out of the basket 103, empty baskets are loaded on the truck 104 and returned to the original position for loading fresh tea leaves again.

In the mechanical harvesting and picking work, the most advanced one is a method of using a rail provided between tea trees to move an automatic tea mower and cutting the tea. The raw tea leaves harvested by the method are finally packed in a bag by the method shown in FIG. The packed green tea leaves are loaded into ordinary trucks and unloaded at the collection point.

[0005]

In transporting the above-mentioned conventional raw tea leaves, during the summer when the temperature is high, the raw tea leaves on the bottom of the bag are steamed and are damaged because of the raw leaves, and the quality is deteriorated. . In addition, fresh tea leaves need not only be packed in a bag when they are transported, but also need to be taken out of the bag when they are unloaded. Therefore, there is a problem that loading and unloading takes time.

12 and 13 are conceptual diagrams for explaining the usage and operation of the dump truck according to the above embodiment of the present invention. In FIG. 12, raw tea leaves 101 cut from a tea tree 100 and packed in a bag 102 are taken out of the bag 102 and transferred to the packing box 15 of the dump truck 1. In this case, the front and rear panel lock mechanisms 12 on the upper panel 10a of the side panel 10 are unlocked, and the upper panel 10a is unlocked.
With a opened and folded, a loading operation is performed.
This makes loading work easy and easy. Next, when the luggage box 15 is almost full to the depth of the lower panel 10b, the upper panel 10a is closed and the panel lock mechanism 12 is used to move the front panel 9 and the rear panel 11 together.
Then, the upper panel 10a is locked and locked. In this state, the depth of the cargo box 15 becomes deeper, so that the loading work is performed using the stepladder 86 or the like.

After the loading is completed, as shown in FIG. 13, the upper surface of the packing box 15 is covered with a hood 87 to prevent the fresh tea leaves 101 from flying while the dump truck 1 is running. At this time, the ventilation device 7 is operated. The dump truck 1 is operated to transport and move the load to a predetermined place on the tea leaf collection area 105. The dump truck 1 is stopped backward in the groove 91, the rear gate 25 is opened, and then the hoist cylinder 2 is operated to dump up the luggage carrier body 4. By this dump up, the rear panel 11 is automatically opened. As a result, the raw tea leaves 1 are transferred onto the conveyor 92 for automatic conveyance.
Drop 01 and unload.

According to the above-described embodiment, the ventilation device 7 can be easily attached to the conventional dump truck, and the ventilation device 7, the net rack 6 and the carrier frame 8 can be used at the time of agricultural work other than the tea leaf harvesting season.
It is possible to use it as a normal dump truck by simply closing the mounting opening 31 by removing it and placing a floor plate on the cargo bed floor 5, and since both side panels 10 can be folded in two steps up and down, There is an advantage that loading work can be done efficiently from either side.

The present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the invention. For example, it can be used for carrying loads other than raw tea leaves.
