Description

[Detailed Description of the Invention] This invention relates to an improvement of a skirt belt attachment device in a belt conveyor.

When conveying materials such as ore using a belt conveyor, the conveyor belt may spill, especially near the chute.In order to prevent this, flexible parts are installed on the longitudinal sides of the belt conveyor. A skirt belt may be provided.
Traditionally, the skirt belt has been affixed to a fixed skirt attached to the frame of the belt conveyor. That is, as shown in FIG. 3, a plurality of inverted L-shaped mounting brackets 22 are fixed at appropriate intervals to a fixed skirt 21 attached to a frame (not shown) of a belt conveyor. After the skirt belt 23 is brought into contact with the outer surface of the skirt belt 21, a wedge 24 is driven between the outer surface of the skirt belt 23 and each of the above-mentioned mounting brackets 22 to fix the skirt belt 23, or a fixing method is used to fix the skirt belt 23 to the fixed skirt using bolts and nuts. A means (not shown) was used to do so.

However, as mentioned above, the fixed skirt 2
When the upper half of the skirt belt 23 is fixed to the conveyor belt 25 and the skirt belt 23
If the conveyor belt 25 gets caught in the small gap between the bottom edge and the conveyor belt 25, it will not be easily removed, and the conveyor belt 25 will drag the conveyor belt 25 with the object caught, causing damage to the conveyor belt and skirt belt. Damage could occur due to wear and tear.

The skirt belt attachment device of this invention was proposed to solve the above-mentioned problems, and is a belt presser with a weight attached to the outside of the fixed skirt provided on the side of the conveyor belt. It is characterized in that the skirt belt is suspended from the fixed skirt or another fixed member so as to be close to each other, and the skirt belt is sandwiched between the fixed skirt and the belt holder.

This invention will be explained below based on the embodiment shown in FIGS. 1 and 2.

1 is a conveyor belt, 2 is a chute, and 3 is a fixed skirt fixed to a frame (not shown) of the belt conveyor. The fixed skirt 3 is made of a strong material such as a steel plate, and is usually provided on both sides of the conveyor belt 1 along with a skirt belt 5 (described later) over a distance of several meters to several tens of meters from the chute 2.

A belt holder 4 is made of a strong material such as an iron plate and has a rectangular front view, and is used to hold the skirt belt 5 between it and the fixed skirt 3, as will be described in detail later. The belt presser 4 is held close to the outer surface of the fixed skirt 3 so as to be suspended from above. In the illustrated example, a plurality of L-shaped hanging pieces 6, 6 fixed to the outer surface of the fixed skirt 3, an inverted V-shaped hanging member 7 fixed to the corresponding position on the outer surface of the belt presser 4, By hooking the belt holder 7, the belt holder 4 is removably suspended.
It may also be hung from a fixed member other than the above, for example, the frame of a belt conveyor.

Further, a weight 8 is mounted on the outer side of the belt presser 4.
is provided removably or fixedly. The weight 8 in the illustrated example is detachably provided, and the legs of a U-shaped mounting member 9 are fixed to the outer surface of the belt presser 4, and between the mounting member 9 and the belt presser 4. A plurality of inverted V-shaped hanging members 10, 1 each having one end fixed to the body of the cylindrical weight 8 are inserted into the formed insertion hole 9a.
The other end of 0 is inserted.

As is conventionally known, the skirt belt 5 is made of a highly flexible rubber-like elastic material, and in the present invention, it is inserted between the outer surface of the fixed skirt 3 and the inner surface of the belt presser 4, and Weight 8 on presser foot 4
Due to the presence of the belt, the belt presser 4 is pressed and held by the belt presser 4 which acts in close contact with the fixed skirt 3 side. That is, since the belt presser 4 is suspended (hanging) with the top of the hanging member 7 serving as the point of suspension P, it is possible to swing outward about the point of action P. A horizontal component of gravity due to the weight 8 attached to the outer side of the belt 4 acts inward, thereby sandwiching the skirt belt 5 between the stationary skirt 3 and the stationary skirt 3. The lower end side of the skirt belt 5 may be in contact with the upper surface of the conveyor belt 1, or may have a slight gap between it and the upper surface.

In addition, in the present invention, the skirt belt 5 and the fixed skirt 3 can be provided on both sides or one side of the belt conveyor, and the location where they are installed is not limited to the chute 2 portion. Further, it goes without saying that a plurality of belt pressers 4 for pressing the skirt belt 5 against the fixed skirt 3 may be provided for one skirt belt 5. Furthermore, a type in which the weight 8 can be removably locked to the belt presser 4 not only makes handling easier, but also allows the belt to be attached to the skirt belt according to the drive speed of the conveyor belt 1 or the type of material to be transported. When changing the clamping force of the weight 8, it is possible to easily change the weight 8 to another weight having a different weight.

According to the above-described skirt belt attachment device for a belt conveyor of this invention, the conveyed object M on the conveyor belt 1 falls sideways and tries to fit into the lower end sides of the conveyor belt 1 and the skirt belt 5. Also, the lower part of the skirt belt 5 is pushed by the conveyed object M, and the belt presser 4, which is suspended and can swing outward, is pushed slightly outward against the pressing force of the weight 8. As the belt presser 4 is tilted, the lower part of the skirt belt 5 also slightly expands in the direction of arrow A, so that the object M is almost completely prevented from being caught. Furthermore, when the conveyed object M that was in contact with and pressed against the skirt belt 5 moves and disappears, the belt presser 4 returns to its original position due to the horizontal force of the weight 8, and the skirt belt 5 automatically returns to its original state. Return to target.

Therefore, according to the present invention, damage to the conveyor belt 1 and the skirt belt 5 caused by the object M being caught in the conveyor belt 1 and the skirt belt 5 can be significantly reduced, and the service life of the conveyor belt 1 and the skirt belt 5 can be greatly extended.
