Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a backfilling device for backfilling excavation with earth and sand.

[0002]

2. Description of the Related Art In order to backfill earth and sand in a portion excavated by an excavator in civil engineering work, such as pipe laying work, earth and sand for backfilling is carried in by a dump truck or the like and loaded and unloaded from its loading platform. .

[0003] In such unloading, when there is a sufficient place to stop the car and the excavation area is large, the loading platform can be tilted by the lifting action of the loading platform and can be discharged from the end as it is. If the excavation area is narrow or the excavation groove width is narrow, it must be lowered manually.

[0004]

[Problems to be Solved by the Invention] Such manual loading and unloading is inefficient, and the work is poor on scaffolding where the loading platform is occupied by earth and sand.

On the other hand, a mechanized shovel such as a backhoe may be used. However, the shovel car itself needs to be installed, and a wide range of road occupation is required, which causes traffic congestion and a boom for supporting the shovel bucket. At the time of turning, the bucket portion and the rear portion jump out of the occupied range, giving a feeling of anxiety to a passing vehicle driver or a pedestrian.

An object of the present invention is to eliminate the disadvantages of the above-mentioned conventional example, and to efficiently backfill soil and sand from a truck bed without human intervention and without using a large excavator. Is to provide a backfilling device that can easily perform backfilling.

[0007]

In order to achieve the above object, the present invention is mounted on a carrier such as a truck, and has a sediment intake opening and a sediment discharge opening in a main body movable by casters. A sand collecting device provided with a transport mechanism by a screw-incorporated cylinder between the opening and the earth and sand sending port, and an earth feeding pipe having one end connected to the earth and sand sending port of the sand collecting device and having a discharge nozzle at the other end. And the fact that a pressure feed mechanism by the exhaust gas of the vehicle is attached to the earth and sand discharge port.

[0008]

According to the first aspect of the present invention, the sand collecting device placed on the carrier such as a truck takes in the sediment on the carrier through the sediment intake opening while sequentially moving the place by the casters, and uses the screw to sediment. Collect and send to the outlet. Then, the earth and sand is discharged from a discharge nozzle disposed on the excavation portion through a soil pipe from the discharge port into the excavation groove. In this way, the earth and sand for backfilling mounted on a bed such as a truck is mechanically carried into the excavation trench, and backfilling is automatically performed.

According to the second aspect of the present invention, in addition to the above-mentioned functions, the earth and sand can be sent farther and at a higher speed by using the exhaust gas of the vehicle to pressure-pipe the pipes. Can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail with reference to the drawings. 1 to 5 show one embodiment of the backfill device of the present invention. FIG. 6 shows a use state.

In FIG. 6, reference numeral 1 denotes a dump truck, 1a
Is the carrier. The sand collecting device 2 is placed on the carrier 1a.

The sand collecting device 2 is movable by providing a plurality of casters 3 on the lower surface of the circular drum type main body 2a. The casters 3 may be self-propelled with one of them as driving wheels, or may have a wireless or remote control steering mechanism.

A screw 4 is provided at the center of the main body 2a.
And a cylinder 5 having a driving motor 4a for the screw 4 provided at an upper end thereof.
In addition, an earth and sand discharge port 7 is provided at an upper position. In this manner, the earth and sand intake opening 6 and the earth and sand discharge port 7 are connected by the transport mechanism using the cylinder 5 having the screw 4 built therein.

Further, a vehicle 16 is connected to the earth and sand discharge port 7.
A pumping mechanism 11 consisting of a merging pipe for feeding the exhaust gas of
Attach 12 and connect the root of the soil feeding pipe 8 provided with the discharge nozzle 9 at the other end via the adapter 12. It is also conceivable to provide the pumping mechanism 11 on the adapter 12 side.

Next, the method of use will be described. The backfill 1a of the dump truck 1 is loaded with earth and sand for backfilling, and the sand collecting device 2 is placed on the earth and sand. A hawklift or a hawklift-like crane truck 13 is arranged behind the dump truck 1, and an excavation groove 14 in which a pipe material 15 is set exists beyond the hawlift.

The crane truck 13 supports a rectangular outer frame 18 extending in the front-rear direction above the vehicle 16 with a plurality of lifting legs 17 standing upright from the vehicle 16 so as to be able to move up and down.
A rectangular inner frame 19 that slides so as to protrude forward and backward with respect to 18 is provided.Furthermore, a running rail 21 of a hoist or other elevating machine 20 extends along the length direction of the inner frame 19, and
It was provided to be able to move laterally in the width direction.

Further, the crane truck 13 is provided with a protruding rod type compacting device 22 and the like. At the same time, the discharge nozzle 9 is held above the excavation groove 14, and the soil transfer pipe 8 from the discharge nozzle 9 is provided. Is connected to the sand collecting device 2. Further, an air supply hose 23 from an exhaust pipe of the vehicle 16 of the crane truck 13 is connected to the pumping mechanism 11.

This completes the setting. The sand collecting device 2 moves sequentially on the carrier 1a with the casters 3,
Take in the sediment on the loading platform 1a from the sediment intake opening 6,
It is collected and sent to the earth and sand discharge port 7 by the screw 4.

The earth and sand is discharged from the earth and sand discharge port 7 through the earth feeding pipe 8 and into the excavation groove 14 from the discharge nozzle 9, and the earth and sand for backfilling mounted on the loading platform 1a is mechanically Is carried into the excavation trench 14 and backfilling is automatically performed.

At the earth and sand sending-out port 7, exhaust gas of the vehicle 16 is sent in by the pumping mechanism 11 to send the earth and sand by pipe.

[0021]

[Effects of the Invention] As described above, the backfilling device of the present invention is capable of efficiently transporting the earth and sand from the truck bed without manpower and without using a large excavator. And can be easily backfilled.
