The loading platform 2 has left and right side surfaces 2a, 2a in the width direction of the vehicle 1 which are inclined toward the center of the bottom surface, and a front side surface and a rear portion in the front and rear direction of the vehicle 1. The side surface is also inclined toward the bottom surface side, so that the civil engineering material a in the loading platform 2 easily flows down toward the bottom center side.

A discharge groove 2b is elongated in the center of the bottom surface of the loading platform 2 in the vehicle direction, that is, in the front-rear direction of the vehicle 1. Below the opened discharge groove 2b, a discharge path 5 for discharging the civil engineering material a in the loading platform 2 is disposed along the discharge groove 2b in the front-rear direction of the vehicle 1. I have.

Left and right side surfaces 2a, 2a of the loading platform 2 which are inclined
A plurality of elastic plates 3 for elastically reciprocatingly reciprocating toward the inner side of the loading platform 2 are attached at regular intervals to the inner surface side. For example, a rubber plate is used as the elastic plate 3.

Each of the elastic plates 3 repeatedly elastically deforms toward the inside of the loading platform 2 to swing the civil engineering material a inside the loading platform 2 so that the civil engineering material a is moved to the discharge groove 2b. The formation of a so-called bridge on the upper side is prevented,
This serves to prevent the liquid from flowing down into b.

Left and right side surfaces 2a, 2a of the loading platform 2 inclined
Are formed with a plurality of notches 2c each having a rectangular shape and a certain size at a certain interval, and each elastic plate 3 is attached to each notch 2c from the inner surface side. That is, each elastic plate 3 is attached so as to be elastically deformed toward the inside of the loading platform 2.

At the outside of the loading platform 2 in which the notch holes 2b are formed, pressers 4 for pressing the elastic plates 3 toward the inside of the loading platform 2 at regular intervals are attached. The pressing machine 4 repeats the pressing motion to swing the elastic plate 3 toward the inside of the loading platform 2. For example, a hydraulic cylinder is used for the pressing machine 4.

Each pressing device 4 is provided with a piston 4a which moves forward and backward toward the elastic plate 3, and a pressure head 4b which directly presses the elastic plate 3 is provided at the tip of the piston 4a. The pressing surface of the pressing head 4b is formed in a partially spherical shape. Each pressing machine 4 is vertically attached to each inclined elastic plate 3 by a connecting beam 4c.

The discharge path 5 disposed below the discharge groove 2b at the center of the bottom surface of the loading platform 2 has both longitudinal front and rear ends extending outward from the front and rear ends of the loading platform 2, respectively. A discharge port 5a is formed at a lower portion on the rear end side of the discharge path 5 extending outward and rearward from the rear end of the loading platform 2. The discharge port 5a is a place where the civil engineering material a sent out in the discharge path 5 is discharged.

A screw conveyor 6 is provided inside the discharge path 5 in the longitudinal direction. The screw conveyor 6 is a device that sends out the civil engineering material a in the loading platform 2 that has flowed down into the discharge path 5 toward the discharge port 5a on the rear end side of the discharge path 5, and the screw 6b is helically wound around the rotating shaft 6a. It has a structure formed in a shape. The screw 6b formed around the rotation shaft 6a is for directly sending out the civil engineering material a, and is formed toward the discharge port 5a of the discharge path 5.

The rotary shaft 6a of the screw conveyor 6 is arranged in the longitudinal direction of the discharge path 5, and the front end of the rotary shaft 6a passes through the front end of the discharge path 5 and is located in front of the front end of the discharge path 5. The rear end of the rotary shaft 6a is rotatably supported by the rear end of the discharge path 5 in a linked manner with a drive motor 7 provided on the outside.

The drive motor 7 composed of a hydraulic motor is
For example, it comprises a hydraulic circuit as shown in FIG. The hydraulic circuit includes a hydraulic pump 7a, a manually operated valve 7b, a throttle valve 7c.
And so on. These devices constituting the hydraulic circuit are provided in a box 7 installed on the loading platform in front of the loading platform 2.
d.

In the lower part on the rear end side of the discharge path 5, the civil engineering material a sent out from the discharge port 5a of the discharge path 5 is sent to the side of the road or directly above the long groove dug along the side band and there. A discharge conveyor 8 is provided for discharging the water downward.
For example, a belt conveyor is used as the discharge conveyor 8.

The discharge conveyor 8 is located at the rear end of the vehicle 1.
Are provided in parallel with the width direction. The entire discharge conveyor 8 is movable in the front-rear direction, and when the discharge conveyor 8 is used, the discharge conveyor 8 moves in the width direction of the vehicle 1 so that the leading end side 8a of the conveyor projects from the side.

The discharge conveyor 8 has a conveyor tip 8a which is rotatable in a horizontal direction about the lower side of the discharge port 5a when the conveyor tip 8a projects in the width direction of the vehicle 1. The distal end 8a can be freely adjusted in the discharge direction.

Next, the operation based on the configuration of the above embodiment of the present invention will be described below. The civil engineering work material a made of sand, asphalt material, or the like is buried in a long groove formed along the side band of the road, or the construction work material a is loaded at the construction location b where the side band portion of the road is paved. The vehicle 1 loaded on the vehicle 2 is driven to move. The traveling direction of the vehicle 1 is moved by driving the civil engineering material a so as to be parallel to the construction location b.

Next, the discharge conveyor 8 attached to the rear end of the vehicle 1 is horizontally moved in the width direction of the vehicle 1 so that the front end 8a of the conveyor projects from the side end of the vehicle 1 in the width direction. The conveyer tip side 8a is located above the construction location b.

After that, the pressing machine 4, the drive motor 7, and the discharge conveyor 8 are operated, and while confirming that the civil engineering work material a falls to the predetermined work place b from the conveyor tip side 8a, the vehicle 1 is checked. Is moved at a low speed along the construction site b.

When the pressing machine 4 operates, the piston 4a of the pressing machine 4 repeats the forward and backward movement toward the elastic plate 3. That is,
When the piston 4a of the pressing machine 4 advances toward the elastic plate 3, the pressing head 4b attached to the tip of the piston 4a
Moves forward and contacts the elastic plate 3.

The contacting pressing head 4b moves while further pressing the elastic plate 3 toward the inside of the loading platform 2. For this reason, the elastic plate 3 pressed by the pressing head 4 b moving forward is elastically deformed into a convex shape inside the loading platform 2.

After the piston 4a has advanced most and extended, it starts to retract. When the piston 4a starts to retreat, the pressing head 4b at the tip of the piston 4a also starts to retreat. When the pressing head 4b retreats, the elastic plate 3, which has been elastically deformed toward the inside of the loading platform 2 by the pressing head 4b, is restored to its original flat state by the elastic force.

When the pressing machine 4 repeats the forward and backward movements in this manner, the elastic plate 3 pressed by the pressing machine 4 repeatedly swings in a convex manner toward the inside of the loading platform 2 by being elastically deformed.
A plurality of elastic plates 3 provided on the inclined left and right side surfaces 2 a of the loading platform 2 repeatedly elastically deform inwardly toward the inside of the loading platform 2 to swing, thereby forming a discharge groove of the loading platform 2. The civil engineering work material a on the upper side of 2b also swings.

When the civil engineering material a on the upper side of the discharge groove 2b swings, a so-called bridge which causes clogging by the civil engineering material a itself is formed on the upper side of the discharge groove 2b by its own weight or the like. Can be prevented.
As a result, the civil engineering material a inside the loading platform 2 smoothly flows down into the discharge channel 5 from the discharge groove 2b on the bottom center side of the loading platform 2 without being clogged.

The civil engineering material a that has flowed down into the discharge path 5 is sent out toward the rear end side of the discharge path 5 by a screw conveyor 6 rotated by a drive motor 7. The civil engineering material a sent out toward the rear end side of the discharge path 5 by the rotating screw conveyor 6 is discharged downward from a discharge port 5a formed in a lower portion on the rear end side of the discharge path 5.

The civil engineering material a discharged from the discharge port 5a is located below the discharge port 5a on the rear end side of the discharge conveyor 8, and falls on the rear end surface of the discharge conveyor 8 to be driven. The sheet is conveyed toward the front end side 8a of the conveyor by the discharge conveyor 8. Because the conveyor tip side 8a is located above the construction location b, the civil engineering construction material a sent to the conveyor tip side 8a surely falls to the construction location b below.

At this time, the vehicle 1 is moving at a low speed, and the conveyer tip 8a projecting laterally from the rear end of the moving vehicle 1 is also moving, and the conveyer tip is moving. 8a, the civil engineering material a is continuously dropped and discharged, so that the civil engineering material a is successively and successively and reliably applied to the construction location b of the civil engineering material a formed along the moving direction of the vehicle 1. It can be sent out and constructed.

In the case where the construction point b is bent during construction and the construction point b cannot be maintained parallel to the traveling direction of the vehicle 1, the discharge conveyor 8 is moved to the conveyor tip end 8a around one end. Swivel horizontally,
Alternatively, by moving the discharge conveyor 8 in the front-rear direction,
It is adjusted so that the conveyor tip side 8a is always positioned above the construction location b.

It should be noted that the present invention is not limited to the above embodiment of the present invention, and it is needless to say that various modifications can be made without departing from the spirit of the present invention.

[0038]

As is apparent from the above description, according to the vehicle provided with the civil engineering material discharge device according to the present invention, the granular civil engineering work made of the protective sand in the long groove excavated along the side zone of the road. The material can be reliably poured into the long groove without spilling around the long groove, and the post-processing work by spilling around the long groove as in the conventional case can be completely eliminated, and the manpower to perform the post-processing work can be eliminated. The work time for post-processing can be omitted, and the work time can be reduced. In addition, since no shovel is used, no special operator who operates the shovel is required, and even a worker who does not have special skills can easily perform the work. Also, when asphalt material is paved on the side of the road, the asphalt material can be surely sown on the pavement portion in the same manner as described above, so that the number of workers can be reduced and the work time can be shortened. . In addition to this, it is possible to prevent a state in which the so-called bridge is formed in the loading platform and the granular construction material is not discharged smoothly, and the granular construction material in the loading platform is smoothly placed above the construction site. Can be sent out.
As described above, in the work of applying the granular civil engineering work material to the work site, it is possible to improve the work efficiency and to reduce the work cost. is there.

In the case of the second aspect, the tip of the conveyer is projected to the side of the vehicle so as to see the tip of the conveyer from which the civil engineering material is discharged from the driver's seat while driving the vehicle. It is possible to check the progress of work, and to immediately know that civil engineering construction material discharged from the tip of the conveyor is discharged to a location off the construction site, Can be prevented from occurring.

Further, in the case of the configuration of claim 3,
Even when the construction site is bent, it can be adjusted so that the tip side of the conveyor from which the civil engineering construction material is discharged and dropped is always located above the construction site.
