JPS5941409B2 - Discharge plate support device in slide dump - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support device for a discharge plate in a slide dump truck provided with a discharge plate that is movable back and forth into a cargo box.

Conventionally, in some dump trucks of this type, rollers are provided on the discharge plate, while guide rails are formed on the cargo box, and the discharge plate is guided and supported by these guide rails and rollers. The disadvantage was that the structure was complicated and balance adjustment was difficult.

The object of the present invention is to obtain a support device for a discharge plate that eliminates the drawbacks of these conventional devices, in which a holding member is provided extending on the side wall of a cargo box, and a support member is provided at an appropriate position on the discharge plate on the inner surface of the cargo box. The sliding member that comes into contact with the presser member is fixed, and the discharge plate is balanced vertically and horizontally.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Reference numeral 1 denotes a cargo box mounted on a vehicle frame 2;
It is composed of left and right side walls 3, a front wall 4 and a bottom wall 5, and a rear fan door 6 is pivotably supported 7 at the rear thereof so as to be openable and closable.

Reference numeral 8 denotes a holding member attached to the upper surfaces of the left and right side walls 3, and the holding member 8 extends over the entire length of the side wall 3 so that its tip protrudes inward of the cargo box.

Reference numeral 9 denotes a discharge plate, and a scraper plate 10 is installed at the bottom of the discharge plate, and a multistage hydraulic cylinder 11 for moving the discharge plate back and forth is pivotally mounted between the discharge plate 9 and the front wall 4.

On the other hand, an L-shaped lower pad 12 is fixed to the lower corner of the discharge plate 9 in the front-rear direction, and the pad 12 is in contact with the bottom wall 5 and the inner surface of the side wall 3.

Further, an upper pad 13 is provided on the upper surface of the discharge plate 9 so as to make contact with the lower surface of the portion where the aforementioned presser member 8 protrudes inward from the cargo box.
is fixed.

Therefore, the lower pad 12 and the upper pad 13 can keep the discharge plate 9 vertically and horizontally balanced.

14 is a discharge chute connected to the rear of the cargo box 1.

Next, the operation of the apparatus of the present invention will be explained. First, in the state shown in FIG. 1, a cargo box is loaded and then moved to a discharge station.

When arriving at the discharge location, the rear fan door 6 is opened and the hydraulic cylinder 11 is then extended.

When the hydraulic cylinder 11 is extended, the discharge plate 9 attached to its front end comes into contact with the side portions of the lower pad 12 between the left and right side walls 3, 3 of the cargo box 1, and is fixed to the upper end of the discharge plate. The upper pad 13 and the lower part of the lower pad 12 come into contact with the lower surface of the presser member 8 and the surface of the bottom wall 5, respectively, thereby moving forward while maintaining vertical and horizontal equilibrium.

On the other hand, the second embodiment will be described with reference to FIGS. 3 and 4. Reference numeral 15 is fixed to the left and right ends of the front surface of the discharge plate 9 so as to slightly protrude from the outer shape of the discharge plate in the vertical and horizontal directions. The rear pad 15 serves as a sliding member, and the rear pad 15 is removable from the discharge plate 9.

Reference numeral 15' denotes a front pad fixed to the rear side of the discharge plate, which, together with the rear pad 15, maintains the longitudinal balance of the discharge plate 9.

Therefore, in the discharge plate 9, the protruding side end of the rear pad 15 is fixed to the inner surface of the side wall 3 of the cargo box 1, the protruding upper end thereof is fixed to the lower surface of the presser member 8, and the bottom wall 5 is fixed to the lower end of the discharge plate 9. Since the discharge plate 9 and the scraper plate 10 are in contact with each other, the discharge plate 9 can be moved with respect to the inner surface of the cargo box without any gap.

In addition, if the vertical and horizontal balance of the discharge plate 9 with respect to the cargo box 1 is lost due to long-term use, remove the sliding member,
Fix the sliding member again with bolts, etc. and make adjustments.

As described above, in the discharge plate support device of the present invention, since the inner surface of the packing box is configured as a guide, there is no need to provide rollers on the discharge plate, and furthermore, a guide rail that engages with the rollers is installed in the cargo box. This is not necessary, and as a result, the inside of the packaging box can be made relatively large.

In addition, the vertical and horizontal balance of the discharge plate with respect to the cargo box can be achieved at the same time between the inner surface of the cargo box, the holding member, and the sliding member fixed in place around the discharge plate. This has the advantage that it can be easily adjusted even in the event of an accident.
