JPS5871228A - Cargo case for dump truck - Google Patents

Abstract

PURPOSE:To selectively perform either a small amount of dumping or a great amount of dumping using a single cargo case by rotatively fitting a pair of slide plates to the rear flapping door provided with dumping port. CONSTITUTION:When powder or the like is dumped, it is guided to a dumping port 8 side by means of a slide plate 12 and is dumped a bit from a dumping port 8 when an opening/closing cover 10 is opened and a cargo case 1 is tilted since the lower end of the rear flapping door 6 is fastened by a hooking device 7. When earth and sand or the like is dumped, if the fastening of the rear flapping door 6 is released by revolving the slide plate 12 inside, covering the dumping port 8, tilting the cargo case 1, and operating the hooking device 7, the rear flapping door 6 swings by its dead weight and the whole rear of the cargo case 1 is opened and then earth and sand is dumped.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a loading box for a dump truck, and particularly to a loading box f that can be used to arbitrarily discharge a small amount or a large amount of loaded material.

The load of the Congo Song dump truck, especially the small amount of the loaded material [I1 should be discharged or carried out A F l-7 The cargo box was discharged into the backward thrust []' Jt role further discharged the loaded material 1] (after fine writing to lead to) Is it a counterfeit VF with slide plates welded to the 5 corners? tsu fl/-1 m.

However, if only a small amount of discharge is required (9), there is a problem (1) (8) In order to make effective use of the truck, there is a problem when transporting a load that does not require a small amount of discharge, such as earth and sand. In some cases, in that case, the rear power instigation Is &-open seven [
However, there was a drawback that the slide plate was bent and a small amount could only be discharged, and it took a long time to discharge.

In order to solve the above-mentioned drawbacks, the present invention provides a slide plate at the rear corner of the box for items that require the discharge of a small amount of loaded material, such as powder or granular material, so that the loaded material can be dust or sand. For items that do not require a small amount of discharge, such as items, the sliding plate can be stored in the rear fan door, and the sliding plate can be used as a hanging F matamono.

The following embodiment will be explained with reference to the drawings. ill i- is assembled (

As described above, the present invention pivots a pair of slide plates to a rear fan door having a discharge port, and by rotating the slide plates outward, the loaded material is guided to the discharge port side, and the slide plate is rotated outward. By providing a pivot point, the rear door can be swung integrally with the side sliding door, so it is possible to selectively discharge a small quantity or a large quantity from one cargo box.
