[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carry-out conveyor for continuously carrying out earth and sand.

[0002]

2. Description of the Related Art As a conventional unloading conveyor, as shown in FIG. 7, a closed loop casing formed by connecting left and right of a plurality of earth and sand unloading plates 1 to an annular chain 2 and folding them back at both ends. Insert the chain 2 into the pipe 4 along the axis of the casing pipe 4,
The chain 2 is driven by a motor or the like to continuously carry out the earth and sand put into the casing pipe 4,
Some of them are discharged from the discharge port 4a on the ground side portion of the casing pipe 4. In the figure, 7 is a hopper into which the earth and sand discharged from the discharge port 4a are input, 8 is a dump truck that conveys the discharged earth and sand, 9 is a floor slab of the building to be constructed, and 18 Is a backhoe that transports earth and sand.

Here, in such a carry-out conveyor, at an appropriate position along the length direction of the casing pipe 4 (in the figure,
At two positions A and B corresponding to each root cutting surface, a wall body 11a surrounding the casing pipe 4 and having an opening surface gradually increasing from the lower side to the upper side is provided, and the wall body 11a is provided.
A hopper device 11 for guiding earth and sand into the casing pipe 4 is attached along the above.

Further, a lower unit 10 is provided at a turning point of the lower portion of the casing pipe 4, and the lower unit 10 is provided with a wall 12a whose opening surface gradually increases from the lower portion to the upper portion, and , A hopper device 12 for guiding the earth and sand into the lower unit 10 along the wall 12a
Is attached.

[0005]

However, in the conventional carry-out conveyor, the wall bodies 11a, 12a are loaded by throwing earth and sand into the hopper device 11 fixed to the casing pipe 4 or the hopper device 12 provided in the lower unit 10. Since the inner surface of the container is slid and guided into the casing pipe 4 or the lower unit 10, when the soil is gravel soil, it is smoothly guided into the casing pipe 4 or the lower unit 10, but In the case of, if the supply is equal to or less than the carrying capacity of the carry-out conveyor, it is smoothly guided like sand and gravel, but if the supply is carried out above the carry capacity of the carry-out conveyor, as shown in FIG. 8 or 9, The earth and sand are walls 11a, 1
It adheres to the inner surface of 2a to form an arch shape (see 14 in the figure) and narrows the openings of the hopper devices 11 and 12. As a result, the charged sand cannot be guided into the casing pipe 4, and the sand is removed from the hopper device. There is a problem of overflow from 11 and 12.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a carry-out conveyor that can smoothly guide even cohesive soil into a casing pipe.

[0007]

The carry-out conveyor of the present invention is a closed-loop casing pipe formed by connecting the left and right of a plurality of earth and sand carry-out plates to an annular chain and folding the chain at both ends. In the carry-out conveyor in which the chain and the earth and sand carrying-out plate are inserted in a state along the axis of the casing pipe, and the chain is driven and driven by a motor or the like, an appropriate lengthwise direction of the casing pipe. At a position, a hopper device is provided that includes a wall body that surrounds the casing pipe, and that guides the earth and sand and the like to the earth and sand swallowing portion of the casing pipe along the wall body. At least a part of the wall body of the hopper device has a wall body. An endless belt running from the upper part of the casing pipe toward the soil swallowing part of the casing pipe is attached. Drive means for the belt travel driven toward the sediment swallowing portion of the casing pipe, characterized in that is provided.

[0008]

In the carry-out conveyor of the present invention, the belt is constantly driven toward the earth and sand swallowing section. Therefore, even if the earth and sand adhere to the wall of the hopper device to form an arch, the earth and sand attached to the belt are moved to the casing pipe side,
The adhered earth and sand is scraped off by the earth and sand carrying-out plate moving in the casing pipe. As a result, it is possible to prevent the arching phenomenon from occurring inside the hopper.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A carry-out conveyor according to an embodiment of the present invention will be described below with reference to the drawings. The same components as those of the conventional carry-out conveyor will be described with the same reference numerals.

In the carry-out conveyor of this embodiment, as shown in FIG. 1, the hopper device 20 is fixed at an appropriate position along the length direction of the casing pipe 4.

The hopper device 20 has a flange portion 22 bolted to the lower casing pipe 4b, a flange portion 23 bolted to the upper casing pipe 4c, and the flange portions 22 and 23. And a wall body 21 fixed so as to surround the casing pipe 4d. The casing pipe 4d is configured so that the interior of the casing pipe 4d communicates with the space surrounded by the wall body 21 in a state where there is no portion surrounded by the wall body 21.

Further, the hopper device 20 includes a notch 21a formed by notching a part of the wall 21 on the earth and sand input side, and rollers 24 attached above and below the notch 21a.
25, an endless belt-shaped metal or rubber belt 26 stretched between these rollers 24, 25, and the belt 26 for the earth and sand swallowing portion 27 of the casing pipe 4d.
The roller 24 or 25 for driving the vehicle toward
Drive means (for example, motor) (not shown) for rotationally driving
It has and. Although not shown, a cover that covers the belt 26 is attached to the outer surface of the wall 21.

Next, the operation of the carry-out conveyor of this embodiment will be described.

First, by driving the chain 2 to travel, the earth and sand carrying-out plate 1 is moved in the lengthwise direction within the casing pipe 4. Then, the belt 26 is driven.
Then, the backhoe 18 removes the earth and sand generated during the root cutting work.
And is loaded into the space surrounded by the wall 21 from the upper opening of the hopper device 20. The deposited earth and sand slides on the inner surface of the wall body 21 or by a belt sent to the casing pipe 4d side, so that the casing pipe 4d
It is guided inside and is conveyed downward by the earth and sand carrying-out plate 1 which moves downward in the casing pipe 4d, and is discharged from the discharge port 4a of the casing pipe 4.

Here, even when highly viscous earth and sand is put into the hopper device 20, the viscous soil adhering to the belt 26 is constantly driven from above from inside the casing pipe 4d by driving the belt 26 toward the casing pipe 4d side. It is scraped off by the earth and sand carrying-out plate 1 which moves downward.

As a result, the arching due to the cohesive soil does not occur inside the hopper, and the injected cohesive soil can be guided into the casing pipe 4d. Then, the earth and sand and the like are conveyed to the outside by the moving earth and sand unloading plate 1.

In this way, the belt 2 is driven by driving the driving means.
By running 6 toward the earth and sand swallowing portion 27 of the casing pipe 4d, the earth and sand adhering to the belt 26 attached to the wall body 21 can be removed, and the hopper function can be always maintained in a normal state. Even then, it can be smoothly introduced into the casing pipe.

Although the hopper device 20 is provided in the middle of the casing pipe 4, as shown in FIG. 6, the wall body 51 constituting the lower unit 50 provided at the folding back point of the lower portion of the casing pipe 4. In addition, a cutout 51a similar to that of the above-described embodiment is formed to form the cutout 51a.
Alternatively, the belt 26 similar to that of the above-described embodiment may be installed.

In the above embodiment, the two belts 26 are used.
Are arranged in a substantially V shape, but this is merely an example. For example, as shown in FIG. 4, three belts 30 are arranged in an inverted trapezoidal shape so as to surround the earth and sand swallowing portion 27 of the casing pipe 4. Alternatively, as shown in FIG. 5, one belt 40 may be arranged at a position facing the earth and sand swallowing portion 27 of the casing pipe 4.

Further, although the belt 26 made of metal or rubber is used in the embodiment, a so-called mesh belt in which metal wires are woven in a mesh shape can be used.

Although the outer surface of the belt 26 is a smooth surface in the above embodiment, a plurality of protrusions may be provided depending on the nature of the earth and sand.
