Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveyor device used for lifting and handling of coal, ore, and other bulk materials.

Conventionally, bucket conveyors, bucket elevators,
Scraper conveyors, etc., are used, but when buckets and scrapers are made larger to enable large-capacity cargo handling, loose objects tend to adhere to the inner bottom of the basket and the corner of the scraper. In particular, if there is a lot of moisture or a high viscosity, it tends to stick to the corners, which can significantly reduce the conveyance efficiency.

Based on the above-mentioned viewpoints, the present invention provides a conveyor device that is capable of conveying a large volume on a steep slope, and also enables almost complete ejection of highly viscous cargo at a reversing position. An endless loop that circulates between a carry side that rises at a predetermined angle, a return side that descends at a predetermined angle, an upper inversion section that transitions from the carry side to the return side, and a lower inversion section that transitions from the return side to the carry side. A conveyor belt, a group of support rollers arranged parallel to each other at required intervals in the conveyor belt movement direction to support the conveyor belt on the conveying side, and a lower back wall that connects the lower part of the back wall to the surface of the conveyor belt. Equipped with a group of weir plates with an open front that can swing as a fulcrum, guide rollers provided on the outside of the left and right side walls of each shear plate, and guide rails for controlling the posture of the weir plates that allow each guide roller to freely roll into contact. The points are distinctive.

Next, the apparatus of the present invention will be explained by way of embodiments with reference to the drawings.

FIG. 1 shows an embodiment of the apparatus of the present invention in a partially schematic side view, FIG. 2 shows a partially enlarged longitudinal sectional side view, and FIG. This is a sectional view, and FIG. 4 is a view taken in the direction of the arrow in FIG. As shown in the drawings, in the apparatus of the present invention, a frame 1 supports a large number of support rollers 2 so as to be freely rotatable, and a conveyor belt 3 is supported by these two groups of support rollers.

The conveyor belt 3 has a carrying side A that rises at a steep slope.
and the return side B which is parallel to the back side of this carrying side.
It is a flat belt that circulates between an upper reversing section C that transitions from the carrying side A to the returning side B, and a lower reversing section D that transitions from the returning side B to the carrying side A, and moves endlessly.

Horizontal bars 4 are fixed to the surface of the conveyor belt 3 at regular intervals in the belt length direction.

The horizontal beam 4 is made of rubber, and is either integrally fixed to the rubber conveyor belt 3 during vulcanization, or separately molded and bonded.

Each horizontal beam 4 has left and right side walls 5A, 5A and a back wall 5B.
The lower part of the back wall of a plastic or metal weir plate 5 is fixed with bolts and nuts.

Each weir plate 5 has the lower portions of the left and right side walls 5A, 5A bent inward, and the upper portion of the back wall 5B bent forward, and furthermore, the lower edges of the left and right side walls 5A, 5A are formed into concave curved edges. Rubber plates 6, 6 are provided at the inner lower part of the left and right side walls 5A, 5A to prevent cargo from leaking to the sides.
are fixed with bolts and nuts.

In this embodiment, the rubber plates 6, 6 attached to the left and right side walls 5A, 5A are separate from each other, but they may be integrated. In that case, the left and right side walls 5A, 5
It has a shape with the bottom formed at A.

Guide rollers 7, 7 are attached to symmetrical positions on the outer surfaces of the left and right side walls 5A, 5A of the weir plate 5, respectively, so as to be freely rotatable.

Each guide roller 7, 7 is in rolling contact with an angle iron guide rail 8 attached to the frame 1, and the weir plate 5
performs posture control.

That is, when passing through the carrying side A, the guide rollers 7, 7 roll into contact with the inner surface 8a of the guide rail 8, which is parallel to the surface of the conveyor belt 3, so that the front part of the weir plate 5 is separated from the surface of the conveyor belt 3 by a large distance. It is controlled so that it does not fall away and backwards,
When passing through the upper reversing section C, the front part of the weir plate 5 moves to the return side B with a large distance from the surface of the conveyor belt 3, and the loaded material on the inside of the weir plate 5 is transferred to the discharge chute 9. It is controlled so that it can be released, and furthermore, when passing through the return side B,
Each weir plate 5 is controlled so as not to hang from the horizontal beam 4.

Further, in this embodiment, guide rollers 10, 10 are attached to the left and right side walls 5A, 5A of every other weir plate 5, so as to roll into contact with the inner surface 8b of the guide rail 8, which is perpendicular to the inner surface 8a.

The guide rollers 10, 10 prevent the weir plate 5 and the conveyor belt 3 to which the sheath plate 5 is integrally fixed from swinging and meandering in the left-right direction due to the guide rail 8.

Further, vertical bars 11, 11 made of rubber are fixed to the surface of the conveyor belt 3 along the left and right edges thereof.

The vertical bars 11, 11 are members that prevent the cargo from leaking to the left and right sides, and are unnecessary when the rubber plates 6, 6 attached to the weir plate 5 are integrated and the weir plate is bottomed.

In addition, a supply chute 12 is provided at the lower part of the conveying side A for supplying the cargo onto the conveyor belt 3.

Furthermore, in this embodiment, the pulley 13 in the upper inverted section C serving as a driving pulley and the pulley 14 in the lower inverted section D serving as a tension pulley have the same diameter, but the pulley 13 serving as the driving pulley may have a larger diameter. good.

Furthermore, although the guide rail 8 is made of angle iron, it goes without saying that it may be made of channel steel or other materials.

Since the apparatus of the present invention has the above-described configuration, when the cargo such as coal falls from the supply chute 12 onto the conveyor belt 3 that has been transferred to the conveying side A via the lower reversing section D, it will fall. The loaded objects are received by the weir plate 5 one after another and are gradually raised.

Since the attitude of the weir plate 5 is controlled by the guide rail 8, the rising cargo does not fall, and eventually reaches the upper reversing section C and is discharged into the discharge chute 9.

During this period, each time the back wall 5B fixed to the horizontal beam 4 passes over the support roller 2, the weir plate 5
Since it rides on the support roller 2 and is sung up and down each time, even if the cargo is a highly viscous material, it will not get stuck in the corner between the conveyor belt 3 and the weir plate 5.

Furthermore, when passing through the upper reversing section C, the front end of the weir plate 5 is largely separated from the conveyor belt 3,
The cargo is almost completely discharged into the discharge chute 9.

As is clear from the above description, the device of the present invention can be used even if the width of the conveyor belt is increased and the weir plate is increased to transport a large amount of cargo on a steep slope. Since the plate and the conveyor belt can be given relative rocking while passing through the conveyor side, there is no risk of the cargo being stuck to the sheir plate and the conveyor belt, and a highly efficient cargo handling condition can be maintained. In addition to the quiet operation characteristic of belt-based cargo handling and the ability to save installation space, this system offers advantages over any conventional cargo handling device.
