Abstract

PURPOSE:To improve efficiency by shuttling transport by a method wherein the throwing port of a bag body, equipped with a lid, is supported by a supporting frame on the cargo box and a discharging port, equipped at the bottom of the bag body, is opened on and supported by a tail gate at the rear side of the cargo box while cargoes are loaded selectively to the cargo box or the bag body depending on the kind of the cargo. CONSTITUTION:When coal is to be transported, the supporting frame 5 is risen up at the rear side of the cargo box 2 by extending a cylinder 6, then, the coal is thrown into the cargo box through the fore opening of the cargo box 2, the supporting frame 5 is tilted forwardly when the coal is loaded to a predetermined amount and the surface of the coal is covered by the supporting frame 5 and the bag body 7 to transport it. The unloading of the coal is effected by tilting the cargo box 2 rearwardly by a driving device and opening the tail gate 4. When cement is to be transported, the opening and closing lid 8 for the throwing port of the bag body, tilted forwardly by the contraction of the cylinder 6, is opened, the cement is thrown into the bag body 7 through a hopper above the truck and the lid 8 is closed to transport it when the amount of the cement has arrived at the predetermined amount. Unloading of the cement is effected by tilting the cargo box 2 by the driving device after the tail gate is secured to the cargo box 2 and opening the unloading lid 9. The range of loading cargoes may be widened and, therefore, the relative frequency of shuttling transport may be increased.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cargo box for a truck mainly for transporting powder and granular materials.

General cargo containing powder and granular materials such as coal and earth and sand is usually transported by trucks equipped with open-top boxes. Conventionally, special tank cars have been used to transport hydrophobic powder and granular materials such as cement, and if a partially open cargo box is used, the cement must be packed in bags before being transported. I couldn't.

Therefore, even if, for example, after transporting coal to a predetermined destination, there was a request to transport cement on the way back, the return trip had to be carried out with empty vehicles because it could not be transported.

Therefore, especially in a situation where fuel costs have skyrocketed in recent years, in order to reduce transportation costs, for example, coal is used on the outbound journey, and coal is used on the return journey, regardless of whether it is hydrophobic or non-hydrophobic. There was a need for the development of cargo boxes for freight vehicles that could transport various types of powder and granular materials.

This invention is in response to the above-mentioned need, and is capable of selectively transporting general cargo containing powder and granular materials such as stone, coal, earth and sand, and hydrophobic powder and granular materials such as cement. The purpose is to provide cargo boxes for lorries.

'Hereinafter, embodiments of the present invention will be explained based on the drawings.

A cargo box 2 is arranged on the rear formwork of the freight vehicle 1 so as to be tiltable rearward by a driving device M (not shown).
The upper end and the rear end are opened, and the rear end opening (A) (rear fan door 4) has its both upper ends pivoted to the cargo box 2 side!!13 and is arranged to be openable and closable.

Reference numeral 5 denotes a supporting frame (installed on the packing box 2), which includes a vertical frame 5a whose base end is pivoted to the rear end of the side wall 3 of the packing box 2 so as to be able to freely tilt forward, and a tip end of this vertical frame 5a. and a horizontal frame 5b connected via a link 5C so as to maintain a horizontal state at all times, and both ends of a hydraulic cylinder 6 are pivotally connected between the middle part of the vertical frame 5a and the side wall 3 near the front thereof. Intervening,
The vertical frame 5a is tilted forward or erected by the expansion and contraction movement of the hydraulic cylinder 6.

Note that the horizontal frame 5b always maintains a horizontal state regardless of the attitude of the vertical frame 5a, and when the vertical frame 5a is tilted forward and becomes horizontal, the vertical frame 5a and the horizontal frame 5b are in a straight line,
Both frames are joined to the upper edge of the side wall 3 of the packing box 2.

The input lower a of the bag body 7 formed of a strong sheet with waterproof properties such as canvas fabric is supported at the center part of the horizontal frame 51, and the bottom part of the bag body 7 is supported by the rear fan. A frontage is supported corresponding to an opening 4a opened in the center of the door 4, and an outlet 1'' 7b is formed. Further, an opening/closing M8.9 is attached to the input port 1a and the discharge port 1b of the bag body 7, respectively.

Although not shown in the drawings, if a vibrator device is installed at a suitable place on the back of the floorboard of the cargo box 2, the powder and granules stored in the bag body 7 can be discharged more smoothly.

Next, the manner of use of the above embodiment will be explained by taking as an example the case where the cargo is coal and cement vi.

First, if the load is RI coal, extend the hydraulic cylinder 6 to raise the support frame 5 to the rear side of the cargo box 2, and load the coal from the front opening of the cargo box 2. When the amount of coal put into the container 2 reaches a predetermined amount, the hydraulic cylinder 6 is contracted and the C support frame 5 is tilted forward, so that the support frame 5 and the bag body 7 are attached to the top of the coal in the cargo box 2. covered and transported.

Also, inside packing box 2? The lithium charcoal is discharged by tilting the cargo box 2 backward by a drive device and opening the rear fan door 4.

Next, when the load is cement, the hydraulic cylinder 6 is contracted and tilted forward, and the bag body 7 is placed in the loading lower a in the IC state.
The opening/closing fi8 is opened, and cement is poured into the bag body 7 from an upper hopper (not shown) or the like. And Semen 1
When ~ has reached a predetermined amount, the opening/closing lid 8 is closed and the item is transported.

Incidentally, cement may be introduced from the input lower a of the bag 7 with the hydraulic cylinder 6 extended and the support frame 5 erected.

Further, the cement inside the bag body 7 is discharged by securing the rear fan door 4 to the cargo box 2 side, and then tilting the cargo box 2 using a drive device and opening the opening/closing lid 9 of the discharge port b. This discharge [T] 7b is what is to be done next. At this time, if a vibrator device is provided as described above, the JJI will come out even more smoothly. Although the usage has been described above when the loaded items are coal and cement, it is not limited to these. In particular, the loaded items on the cargo box 2 include not only powder and granules, but also steel materials and equipment. This applies to general cargo such as H.

As explained above, the truck box of this invention is
A support frame is provided on the cargo box, and the support frame supports the input port of the bag, and the bottom of the bag is supported with an opening at the rear end of the cargo box (an opening is formed, and the input port is supported by the support frame). By installing an opening/closing lid on the discharge port, it is possible to selectively load the boxes and bags depending on the type of cargo, so one truck can transport general cargo such as Cb method and steel materials. This makes it possible to transport hydrophobic powder and granular materials such as cement, which cannot be transported using conventional open-F section packing boxes that do not particularly like moisture adsorption. Since the range expands, (1
This reduces the number of times the vehicle is operated empty on the way or return route, making it economical and reducing transportation costs.It also has a simple structure and can be easily implemented by modifying the conventional -F section open type cargo box. In addition, by constructing the support frame as a cargo box so that it can be tilted freely, the load on the cargo box can be covered and protected by the support frame and the bag. eC1 The loaded items can be transported safely and reliably to the destination.Furthermore, if the cargo box is configured to be tiltable as in the above embodiment, and the cargo box is tilted during discharge, the contents of the bag can be transported safely and reliably. This has the effect of smoothing out the discharge of the powder and granules that have been thrown in.
