Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a slide dump truck in which a discharge plate is provided in the dropper box, and the discharge plate is moved backward to push out the load in the dropper box and discharge it from the rear. It is possible to carry out operations beyond the width of the guard box.

Conventionally, slide dump trucks have been known in which a discharge plate is provided inside the cargo box, and the loaded material in the cargo box is pushed out and discharged from the rear by moving the discharge plate rearward. Since the loaded material discharged onto the ground cannot be spread wider than the width of the dump truck, it was not possible to observe the spread state of the loaded material from the driver's side of the slide dump truck.

The purpose of this invention is to obtain a dump truck that eliminates the drawbacks of these conventional devices.A discharge chute is connected to the rear end of the cargo box, and a discharge guide plate is provided on the inner surface of this discharge chute. It is formed to be wide toward the tip, and the tip protrudes to one side of the guard box, so that the loaded material can be spread beyond the width of the cargo box. An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a cargo box mounted on a vehicle frame F, and the cargo box 1 includes a pair of symmetrical side walls 2, 2, a front wall 3, In addition to being composed of a bottom plate 4 and a rear sliding door 5, guide rails 6, 6 are formed on the upper parts of the side walls 2, 2.

7 is a discharge plate, and the discharge plate 7 is connected to the guide rail 6,
It is fixed to a moving frame 8 that slides back and forth while being guided by a frame 6.

Further, a multi-stage hydraulic cylinder 9 for operating the discharge plate is installed between the back surface of the discharge plate 7 and the front wall 3, and the discharge plate 7 can be freely rotated on the movable frame 8 by the expansion and contraction action of the cylinder 9. The rollers 10 supported by the rollers 10 move along the aforementioned guide rails 6, 6 and slide inside the cargo box 1. 11' is a discharge chute whose front end is fixedly integrated with the rear end of the drip box 1 by welding or the like, and a closing opening 15 is formed above the rear end, and the rear fan door 5
When it rotates rearward around the pivot 12, the sekiguchi 15 is blocked by the rear fan door 5, and the entire discharge chute 11 is formed into a rectangular tube shape diagonally downward from the rear end of the tachibana box 1. , inside the bottom surface 16 there are a plurality of discharge guide plates 13,...
... has been erected.

Furthermore, this cylindrical discharge chute 11 projects toward the right end toward its discharge side to a width wider than the width of the cargo box (FIG. 2). Reference numeral 14 denotes a discharge guide plate arranged on the inner surface of the rear fan door 5. Next, to explain the effect of the present invention, first,
In the state shown in the figure, when the ejection hydraulic cylinder 9 is extended after removing the securing device of the rear door 5 (not shown), the ejection plate 7 attached to the front end of the ejection plate 7
, 2 along guide rails 6, 6 provided on the outer surfaces of the cargo box 1, and discharge the loaded items in the cargo box 1 to the ground through the discharge chute 11.

At this time, the rear fan door 5 is pressed by the rearward movement of the loaded object and extends rearward around the pivot plate 12, and the discharge chute 11
In addition to blocking the opening 15 above the rear end to form a part of a rectangular cylindrical discharge chute, the load is divided into two by a discharge guide plate 14 fixed to the inner surface of the chute. Furthermore, the loaded materials such as bones, earth, sand, and ready-mixed concrete that slide down inside the discharge chute 11 are evenly divided by a discharge guide plate 13 that extends from the connection port with the full box to the tip of the discharge chute and fall to the ground. do. As described above, in the present invention, the spread width of the loaded material is wider in the right direction than the width of the loading platform by the discharge chute, so it is possible to discharge the loaded material while observing it from the driver's side, especially while moving the vehicle. When discharging the loaded material, there is an advantage that the work can be carried out without stepping on the ready-mixed concrete or the like that has been previously poured with tires.
