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, as a support device for the discharge plate in this type of dump truck, there is a device that supports the discharge plate against the cargo box using rollers, pads, etc., but these devices support the discharge plate in a fixed posture and position. When doing so, the structure is complicated because it is supported by separate rollers, pads, etc. disposed in the vertical and horizontal directions, and it is difficult to adjust the position of the discharge plate.

The purpose of this invention is to obtain a support device for a discharge plate that eliminates the drawbacks of these conventional devices.A guide rail having a vertically tapered surface is attached to the cargo box side, and this guide rail is attached to the discharge plate side. By providing a supporting tapered row on one surface of the taper, the vertical and horizontal positional adjustment of the discharge plate can be performed simultaneously using the same roller.

An embodiment of the present invention will be described below with reference to the drawings. A is a cargo box, and the cargo box A is composed of left and right side plates 1, 2, a front wall 3, and a bottom plate 4, and a rear door 5 is provided at the rear of the box. is pivoted 6 so that it can be opened and closed freely.

Guide rails 7 and 7' are attached to the outer surfaces of the left and right side plates 1 and 2, and the guide rails 7 and 7' extend over the entire length of the side plates 1 and 2, and their upper and lower surfaces are tapered. There is.

Reference numeral 8 denotes a discharge plate, on the upper part of which is installed a support plate 9, and on the lower part thereof a scraper plate 10, respectively, and between the discharge plate 8 and the front wall 3 is a hydraulic cylinder 11 for driving the discharge plate.
12 and 13 have landed.

Reference numerals 14, 14' denote arm sections hanging from both left and right ends of the support plate 9, and the guide rails 7, 14, 14' of the arm members 14, 14'
There are tapered rollers 15 at the top and bottom positions before and after 7'.
, 16, 17, 18, 15', 16', 17', 18'
are provided respectively, and the tapered rollers 15, 16,
17, 18, 15', 16', 17', and 18' are in contact with the tapered surfaces of the guide rails 7 and 7', respectively;
Its ends are attached to the arms 14, 14' with nuts 19, 20.
, 21, 22, 19', 20', 21', and 22'.

Note that 23, 23, . . . are reinforcing frames provided between the left and right side plates 2, 3 of the loading box 1 and the longitudinal girders 24, 25, and 26 is the reinforcing frame for the loading box 1.
This is a discharge chute connected to the rear of the machine. Next, the operation of the device of the present invention will be explained. First, cargo is loaded in the state shown in FIG. 1, and then the device is moved to a discharge location.

Upon arrival at the discharge location, the rear door 5 is opened and the hydraulic cylinder 11 is extended. When the hydraulic cylinder 1 is extended, the discharge plate 8 attached to its front end moves toward the guide rails 7, 7 attached to the outer surfaces of the left and right side plates 1, 2 of the cargo box A.
' and tapered rollers 5, which are attached to arm sections 14, 14' hanging down from both ends of the support plate 9 attached to the upper part of the discharge plate 8, and support the guide rails 7, 7'.
16, 17, 18, 15', 16', 17', and 18', it moves rearward smoothly while maintaining the positional relationship in the vertical direction and in the direction of the cargo box with respect to the surgery box A, and the loading inside the cargo box A is carried out. The material is discharged through the discharge chute 26. Further, if the positional relationship of the discharge plate 8 with respect to the cargo box A in the vertical direction and in the direction inside the cargo box is disrupted due to long-term use, each tapered roller may be moved back and forth as appropriate.

That is, for example, after loosening the right inner nut and inserting the right outer nuts 19', 20', 21', and 22',
If the left outer nuts 19, 20, 21, and 22 are loosened and the left inner nut is inserted, the discharge plate 8 moves to the left in the direction of the cargo box. Also, loosen the upper inner nut, tighten the upper outer nuts 19, 21, 19', and 21', then loosen the lower outer nuts 20, 22, 20', and 22', and tighten the lower inner nut. Once the discharge plate 8 is pushed in, the discharge plate 8 moves downward so that the scraper 10 comes into approximate contact with the bottom plate 4. By selecting an appropriate nut and moving it forward or backward in this manner, it becomes possible to move the discharge plate 8 in the vertical direction or in the direction into the cargo box.

As described above, in the present invention, a guide rail having a vertically tapered surface is provided on the outer surface of the side plate of the cargo box, and a tapered roller adjustably attached to the discharge plate is attached to the tapered surface of the guide rail. , the discharge plate can be adjusted vertically and longitudinally relative to the cargo box.
It becomes possible to maintain the adjusted posture and move it back and forth.
