It has a box frame shape with the upper part 13b open and a slit 19 formed between the bottom plate 16 and the rear end plate 18 on the bottom side. Therefore, a mounting shaft 20 that also serves as a reinforcing shaft is installed between the front upper parts of the side plates 15, 15, and three contact pieces 21 made of angle iron are provided on the upper surface side of the front edge of the bottom plate 16. The bottom plate 16 is fixed at intervals, and the bottom plate 16 is further reinforced by welding and fixing reinforcing rods 22 made of iron pipe material arranged along the slits 19 at the rear end side. It should be noted that the reinforcing rod 22 may be made of other materials such as angle iron. Also,
Arc-shaped slots 23 are bored in each of the rear end sides of the side plates 15, 15, and nuts 24 are fixed at positions corresponding to the slots 23 on both side edges of the inner surface of the rear end plate 18. The bolt part 25a of the L-shaped handle 25 is screwed into the nut 24 from the outside through the slot 23, and the rear end plate 18 is rotatable around the pivot 17 within the range of the slot 23, and can be rotated as desired. By tightening the handle 25 at this position, the side plate 15 and the flange portion 25b of the handle 25 are brought into pressure contact and fixed. Therefore, the width of the slit 19 can be set arbitrarily.

されている。 On the other hand, on the rear end side of the dump truck loading platform 12, an opening/closing frame plate pivot piece 27 is protruded from the upper part of the rear end of both side frame plates 26, 26, similar to the conventional one. The opening/closing frame plate 28 at the rear end is fixed to the inside upper part and is pivotally connected via a bracket 28a that protrudes upward.
A plurality of lock pieces 28b, 28b are provided at the lower part thereof so as to protrude downward at predetermined positions except when ejecting 4.
It is configured to be fixed to the bottom of the loading platform 12 via. Therefore, both side frame plates 26, 26
At a position closer to the front than the pivot piece 27, hook pieces 29 each having a notch 29a on the front side are protruded.

い。 The chute device main body 13 is attached to the rear end of the loading platform 12 when discharging the loaded object 14, and as shown in FIGS. At the same time, the mounting shaft 20 is engaged with the notch 29b of the hook piece 29 in a state where it overlaps with the outside of the hook piece 29, and the contact pieces 21...
It is attached by bringing it into contact with the rear end surface of the bottom plate 30 of. Under this installation condition, the shoot device main body 13
The main body 13 is held in a stable posture because its weight acts in a direction to rotate the main body 13 toward the vehicle body 11 around the mounting shaft 20. Therefore, the operation of discharging the loaded object 14 is performed by tilting the loading platform 12 after the opening/closing frame plate 28 is in an unlocked state.
As a result of this operation, as shown in FIG. 6, the opening/closing frame plate 28 opens toward the inner space 13c of the chute device main body 13 due to its own weight and the pressure of the loaded object 14. It flows into the interior and falls onto the track bed 31 from the slit 19 at a constant rate. Therefore, if the vehicle body 11 is moved forward at a constant speed during this discharge, a loaded layer 14a of a constant thickness is laid on the road bed 31. Note that since the lock piece 28b provided at the lower end of the opening/closing frame plate 28 is located at a position offset from the contact piece 21 of the shoot device main body 13, there is no problem in the opening operation of the opening/closing frame plate 28.

る利点がある。(Unique effects of the invention) According to the dump truck chute device according to this invention, the falling speed of the loaded material discharged to the rear of the vehicle body can be arbitrarily adjusted by tilting the loading platform, and it is possible to drop the loaded material little by little at a fixed rate. For example, when laying a load with a constant thickness on the base of a road bed during road paving work, etc., the above discharge can be carried out while moving the vehicle forward at a constant speed, eliminating the need for conventional ground leveling using mechanical or human power. The excellent effect is that the work is omitted or simplified and the workability is greatly improved. In addition, since the chute device body is detachable from the loading platform, it is possible to remove everything other than the load discharger so that it does not interfere with the operation of the dump truck, and it is possible to use one chute device body at the construction site. It has the advantage that it can be shared by multiple dump trucks.
