Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to earth and sand, gravel, concrete, mortar, cement, shell grains, coal, coke, and other particles and powders.
The present invention relates to a device for transferring a material to be transferred, which is a fluid material such as a kneaded material or a semi-kneaded material, or a waste material such as dust or paper waste, from a place to another place through a cylinder.

[Prior Art] Conventionally, a cord body is inserted into a long cylindrical body, a transfer body is arranged at an appropriate interval in the cord body, and the cord body is pulled in the longitudinal direction of the cylinder body. An apparatus has been developed for transferring the substance contained in the container by a transfer body.

As a driving means of the above-mentioned conventional transfer device, as shown in FIG. 3, a drive wheel around which a cord is wound is provided with a cutout portion, and the transfer body is rotationally driven while being engaged with the cutout portion.

[Problems to be Solved by the Invention] However, in the above-described conventional drive device, when the spacing between the transfer bodies changes due to the expansion and contraction of the cords, a gap occurs between the transfer body and the cutout portions of the drive wheels, and the transfer bodies are notched. Therefore, there is a problem that the drive cannot be performed as a result, and sometimes the transfer body, the drive wheel and the like are destroyed.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to smoothly and surely rotate a transfer body even if the ropes expand and contract and the intervals between the transfer bodies change. It is an object of the present invention to provide a transfer device that can be driven and that can produce a rope, a transfer body, and the like simply and inexpensively.

[Means for Solving the Problems] A transfer device of the present invention includes an elongated tubular body, a cord body inserted through the tubular body, and a transport body arranged at an appropriate interval in the cord body. Driving means for pulling and driving the cord in the longitudinal direction of the tubular body, means for supplying a substance to be transferred provided in an upstream portion of the tubular body in the pulling direction, and a downstream portion of the tubular body in the pulling direction In the transfer device including the discharge portion provided in the above, the drive means includes an idle wheel around which the rope is wound, a drive rod rotatably provided on at least one side of the idle wheel, and the drive rod. It is characterized in that it is composed of a prime mover that rotationally drives.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes an earth discharging pipe, for example, a structural steel pipe having a certain length is added to form a tubular body having a desired length. The soil discharge pipe 1 is erected in a substantially vertical direction, and an upper part thereof is an upper horizontal part 1a bent in the horizontal direction. The lower part of the earth discharging pipe 1 is also a lower horizontal part 1b bent in a substantially horizontal direction, and a loading hopper 2 is provided in the middle of the lower horizontal part 1b.

A wire 3 as a rope is inserted through the earth discharging pipe 1, extends outward from the discharge port of the upper horizontal portion 1a of the earth discharging pipe 1, passes through the inside of the return pipe 4, Lower horizontal part
Returning to 1b, forming an endless loop as a whole.

Disc-shaped transfer bodies 5 are arranged and connected to the wire 3 so as to keep appropriate intervals therebetween.

A drive device A is disposed in front of the discharge port of the upper horizontal portion 1a of the soil discharge pipe 1.

The drive device A is mainly composed of an idler wheel 6, a drive rod 7, and a prime mover 8, as shown in an enlarged view in FIG.

The idler wheel 6 can freely rotate, and the wire 3 is wound around the groove 6a formed on the outer peripheral surface thereof. Further, the idler wheel 6 is formed with a notch 6b for receiving the transfer body 5.

The drive rod 7 is configured to be rotatable around the same axis as the rotation center axis of the idler wheel 6 independently of the idler wheel 6. Four drive rods 7 are provided on each of the upper and lower sides of the idler wheel 6 so as to contact the rear surface of the transfer body 5. The drive rod 7 may be provided only on one side of the idler wheel 6, and the number thereof may be any number as required.

The drive rod 7 is rotationally driven by a prime mover 8 such as a motor.

Since the transfer device of the present embodiment is configured as described above, when the wire 3 is pulled by the drive device A, the transfer body 5 moves in the earth discharging pipe 1 from bottom to top.

When the excavated soil S is loaded into the loading hopper 2 in this state, the soil S enters the soil discharge pipe 1 between the transfer bodies 5 and is pushed upward by the transport bodies 5 to be transferred upward. It is discharged from the discharge port of the horizontal portion 1a into the hopper 9, further dropped on the belt conveyor 10 and transferred in the horizontal direction.

The idler wheel 6 is positioned in the notch 3b as the wire 3 is wound around in the notch 6b with the transfer body 5 received therein, and the drive rod 7 is rotationally driven in the arrow direction by the prime mover 8. The transfer body 5 comes into contact with the back surface of the transfer body 5 and is forcibly driven to rotate, so that the idle wheel 6 also rotates.

[Effects of the Invention] A long tubular body, a cord body inserted through the tubular body, a transfer body arranged at an appropriate interval in the cord body, and the cord body in the longitudinal direction of the cylinder body. A driving means for pulling and driving, a means for supplying the substance to be transferred, which is provided in an upstream portion of the tubular body in the pulling direction, and a discharge portion, which is provided in a downstream portion of the tubular body in the pulling direction,
In the transfer device, the drive means includes an idler wheel around which the rope is wound, a drive rod rotatably provided on at least one side of the idler wheel, and a prime mover for rotationally driving the drive rod. Therefore, even if the ropes expand and contract and the spacing between the transport bodies changes, the transport bodies can be smoothly and reliably rotated, and the ropes and the transport bodies can be manufactured simply and at low cost. I can.
