Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a bent bucket conveyor structure.

(B) Conventional technology Conventionally, bucket conveyors with buckets attached to the outer surface of the conveyor belt have been uniform for either vertical or horizontal conveyance; This was accomplished by placing the ends of the bucket conveyors in different directions opposite each other and transferring the material from one bucket conveyor to the other.

(c) Problems to be solved by the invention Therefore, during transfer, much of the conveyed material spilled, resulting in a small amount of final conveyance and poor conveyance efficiency.

(d) Means for solving the problem In the present invention, the vertical portion is bent in an upright manner from the horizontal conveying portion via the bending pulley, and the bending pulley is integrally connected to the shaft via the shaft body. On the outer circumferential surface of the supported left and right cylindrical hubs, left and right downstream vanes that have a constant angle with respect to the axis and are gradually constricted downward are connected in a radial manner relative to each other, and the downward constriction between the left and right downstream vanes is created. To provide a bent bucket conveyor structure in which a shaped space is used as a flow path for leakage from a bucket, and another bucket is located below the narrowing of the same flow path.

(e) Effect According to the present invention, when the conveyor belt is rotated, the conveyed objects stored in buckets and conveyed horizontally in the horizontal conveyance section are continuously conveyed in the vertical direction in the vertical conveyance section. The direction change from horizontal conveyance to vertical conveyance is performed by bending the conveyor belt guided by a bending pulley.

Therefore, when the conveyor belt changes direction from the horizontal direction to the vertical direction, it faces the bending pulley, and the pulley rotates as the conveyor belt rotates, and the flow path S is positioned below the bucket 3. However, another bucket 3 is located below the constriction of the flow path S, and leakage from the bucket 3 is stored in the lower bucket 3.

(F) Effects According to the present invention, it is possible to combine horizontal conveyance and vertical conveyance, and when changing the conveyance direction, leakage from the bucket is guided by the falling blades and collected in the lower bucket. , it is possible to efficiently transport objects.

(G) Example The example of the present invention will be explained in detail based on the drawings.
A indicates a bent bucket conveyor, and this conveyor A has a conveyor belt 2 suspended within a conveyor case 1, and a large number of bucket belts 3 attached to the outer peripheral surface 2' of the conveyor belt 2. Thus, the conveyor belt 2 bends from the horizontal conveying section 4 suspended in the horizontal direction through the bending pulley 5 to form a rising vertical conveying section 6, and from the vertical conveying section 6 through the guide rollers 7. The horizontal carry-out conveyance unit 8 is suspended in a bent state, and the conveyed articles inputted from the input port 9 at the base end of the conveyor case 1 are conveyed through the rotation of the conveyor belt 2 while being stored in the bucket 3. , the conveyor case 1 is carried out from the outlet 10 at the tip thereof.

Here, the bending pulley 5 will be explained as follows. That is, the bending pulley 5 is
Left and right cylindrical hubs 1 integrally supported via a shaft body 11
Left and right flow down vanes 14 and 14' having a constant angle θ with respect to the axis 13 are radially connected to each other on the outer peripheral surfaces of the left and right flow down vanes 14 and 12', and the tip edges of the left and right flow down vanes 14 and 14' are shaped like a bucket. 3 is formed into a perfect circular shape in a projected plane so as to guide the conveyor belt 2 by coming into contact with the outer circumferential surface 2' of the conveyor belt 2 on both sides. Therefore, when the conveyor belt 2 is rotated while being guided by the bending pulley 5, the lower constricted space between the left and right flow down vanes 14, 14' facing each other on the lower side of the bucket 3 is removed by the bucket 3.
The flow route S for leakage material is set as follows.

Further, at this time, the bucket 3 is configured to be located below the narrowing of the flow path S.

In addition, in the figure, 15 is a skirt, and the horizontal conveyance section 4
It covers the outer surface 2' of the conveyor belt 2 from the left and right sides.

Further, in the figure, 16 is a drive pulley, and 18 is a guide pulley.

The embodiment of the present invention is configured as described above, and when the conveyor belt 2 is rotated and the conveyed object is inputted from the input port 9, the conveyed object is placed on the conveyor belt 2 by the skirt 15. It is supported without spilling, efficiently stored in the bucket 3, transported laterally by the horizontal transport section 4, and transported vertically by the vertical transport section 6 via the bending pulley 5. However, when the bucket 3 passes opposite the bending pulley 5, the left and right flow down vanes 14, 1 facing each other on the lower side of the bucket 3
4' space becomes the downstream path S and the lower bucket 3
It becomes constricted towards. That is, leakage from the bucket 3 on the left and right downstream vanes 14, 14' is guided by the left and right downstream vanes 14, 14', and is stored in the bucket 3 on the lower side. However,
The objects transported by the vertical transport section 6 are transferred to the unloading transport section 8
It is carried out from the carrying out port 10 via.

Therefore, when changing the direction of the bucket 3 from the horizontal transport section 4 to the vertical transport section 6, leakage from the bucket 3 can also be received by the lower bucket 3, improving transport efficiency.

Therefore, no matter how far away the horizontal distance is,
It can be moved by the horizontal conveyance section 4 and smoothly conveyed in the vertical direction by the vertical conveyance section 6.

Further, since the horizontal carry-out conveyance section 8 is provided on the vertical conveyance section 6, an inclined chute is not required, and the height of the vertical conveyance section 6 can be made as low as possible.

Moreover, the vertical conveyance section 6 can be formed with an arbitrary slope.
