Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a belt conveyor connecting portion conveying device provided at a connecting portion when conveying bulk materials such as ore to another belt conveyor.

When moving bulk materials such as ore or coal from one belt conveyor to another, the structure is such that the fallen materials are collided with a stone box and then stored on the belt conveyor.

Therefore, it has been pointed out that depending on the type of loose material, the loose material may turn into powder and generate dust.

Considering the above facts, the present invention prevents loose objects that have the possibility of powdering or scattering dust by mitigating the impact energy when they fall, and stones that have no risk of powdering. It is an object of the present invention to provide a belt conveyor connecting portion conveying device that enables rapid conveyance by colliding with a box.

The belt conveyor joint conveying device according to the present invention winds an endless belt around drums arranged above and below between a pair of belt conveyors, and has side plates erected on both sides of the endless belt, and a longitudinal direction of the endless belt. A box-shaped space is formed between the side plates by providing a plurality of horizontal plates in a right angle direction.This box-shaped space accommodates loose materials that can be powdered, and is blocked by a drum to prevent collision of loose materials. Energy is alleviated to prevent pulverization, and for loose items with no risk of pulverization, the drum and guide are moved by a drive device and the loose items are transported to a stone box provided on the opposite side of the endless band of the guide and the plate. It is designed to allow rapid transportation by dropping and colliding with each other.

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, the first belt conveyor 10 on the delivery side has a pair of drums 12 arranged horizontally (however, one drum 12 is not shown in FIG. 1), and an endless belt is connected to these drums 12. A band 14 is wrapped around it and driven in the direction of arrow A.

A second belt conveyor 16 having a conveyance direction perpendicular to the conveyance direction of the first belt conveyor 10 (direction perpendicular to the paper surface) is arranged below the first belt conveyor 10. The bulk material 20 dropped from the container 10 is conveyed.

Above the second belt conveyor 16, there is provided a skirt 22 whose inner diameter gradually increases toward the top, so that the falling bulk materials 20 can fall appropriately onto the endless band 18 of the second belt conveyor 16. .

This first belt conveyor 10 and second belt conveyor 16
A connecting portion conveying device 24 according to the present invention is disposed at the connecting portion.

This conveying device 24 has a pair of drums 28 attached to the frame 26.
．． 30 is pivotally supported.

These drums 28, 30 are both arranged horizontally with their axes parallel to the drum 12 of the first belt conveyor 10, and are arranged above and below.

An endless band 32 is wound around these drums 28,30.

In this endless band 32, the intermediate portions of the drums 28, 30 are guided by a plurality of guide rollers 34 which are pivotally supported on the frame 26.

As shown in FIG. 3, a pair of rubber corrugated side plates 36 are erected on both side edges of the endless band 32 (both ends in the direction perpendicular to the plane of the paper in FIG. 1).

Further, a plurality of horizontal plates 38 are erected at appropriate intervals in the longitudinal direction of the endless band 32 in a direction perpendicular to the longitudinal direction, and the bottom part is surrounded by the endless band 32 and the periphery is surrounded by the side plates 36 and the horizontal plates 38. A box-shaped space 40 is provided for transporting bulk items 20.

A stone box 42 that also serves as a guide is provided below the drum 12 of the first belt conveyor 10 and above the second belt conveyor 16, and is fixed to the frame 26.

This stone box 42 has a vertical portion 44 that is a box-shaped space 40.
Its surface (on the right side in FIG. 1) close to the opening of the box-shaped space 40 closes the box-shaped space 40 and serves as a guide to prevent the loose objects 20 from falling from the box-shaped space 40.

Further, an extension part 46 is provided from the lower end of this vertical part 44, which is bent at right angles in the direction opposite to the endless band 32 and extended horizontally. ) and the upper surface of the extension portion 46 are arranged so as to function as a stone box.

The length of the stone box 42 in the vertical direction is such that the upper end is slightly below the drum 12 of the first conveyor 10, and the lower end ends near the endless band 32 that is wound around the drum 30 and bent.

The frame 26 is a trolley 5 on a horizontally laid rail 48.
0, and the drum 28 is driven by the motor 52 on the truck 50 (in the direction of arrow B) to rotate the endless band 32 in the longitudinal direction.

Further, a truck driving motor 54 is provided on the truck 50 so that the truck wheels 56 can be driven together with the frame 26 in the transport direction of the first belt conveyor 10 (left and right direction in FIG. 1).

Here, as shown in FIG. 1, the arrangement in which the loose objects 20 from the first belt conveyor 10 are dropped into the box-shaped space 40 is the first position, and as shown in FIG. 1 Stone box 4 separated from the belt conveyor 10
2 is a loose item 20 that is dropped from the first belt conveyor 10.
The arrangement corresponding to is the second position.

Next, the operation of the above embodiment will be explained.

First, an explanation will be given of the operation when dropping loose materials 20 that may be powdered from the belt conveyor 10 onto the second belt conveyor 16.

The motor 54 drives the cart 50 to the first position, in which the endless belt 32 approaches the first belt conveyor 10 as shown in FIG. 1, and the motor 52 drives the endless belt 32 in the direction of arrow B. When the stone box 42 is moved, the loose objects 20 dropped from the endless belt 14 by the rotation of the first belt conveyor 10 in the direction of arrow A are accommodated in the box-shaped space 40 at the upper part of the stone box 42 .

The stored bulk items 20 are rotated in the direction of arrow B of the endless band 32 so that the open part of the box-shaped space 40 is moved to the stone box 42.
It is closed on the back side and scattered downward.

This loose material 20 is transferred to the drum 30 by the movement of the endless band 32.
When the stones reach the vicinity, the box-shaped space is unblocked by the stone box 42, so that they fall from the box-shaped space 40 and onto the endless belt 18 of the second belt conveyor 16.

The fallen bulk material 20 is conveyed by the endless belt 18 to the end of the second belt conveyor 16 and then to the next process.

Since the bulk items 20 are accommodated in the box-shaped space 40 and conveyed downward, the collision energy due to the fall is absorbed while being accommodated from the first belt conveyor 10 into the box-shaped space and from the box-shaped space to the second belt conveyor 16. Since there is only a head difference between the particles and the impact energy is small, there is significantly less risk of powdering and dust scattering.

Next, when transporting bulk materials with no risk of pulverization, the motor 54 is driven to move the trolley 50 to the second position shown in FIG. Separate it from the belt conveyor 10.

At this second position, the endless band 32 is stopped without driving the motor 52.

The loose objects 20 dropped from the endless body 14 by the drive of the first belt conveyor 10 collide with the back surface of the vertical section 44 and the extension section 46 of the stone box 42 and then fall onto the second belt conveyor 16. Since there is no risk of pulverization, the particles are properly accommodated on the second belt conveyor 16 without scattering dust.

As explained above, the connecting part conveying device according to the present invention uses the endless belt, side plates, horizontal plates, and guides to convey loose materials that are likely to become powdered, thereby preventing powdering and scattering of dust. Bulk items that are not likely to become damaged are dropped into the stone box and stored on the second belt conveyor 16, which has the excellent effect of efficient conveyance.
