Description

[Detailed Description of the Invention] The present invention relates to a support device for a belt conveyor for transporting raw materials, and more specifically, to a support device for a belt conveyor that has an improved structure of a support that supports a roller-shaped carrier. be.

First, the outline of the support section of the belt conveyor will be explained using FIG. 2 showing one embodiment of the present invention.

As shown in Fig. 2, when loading raw materials onto a belt conveyor, both sides of the conveyor belt 3 are held up under and in the vicinity of the skirt portion 1 of the chute of the raw material conveying device. In order to ensure that the belt 3 moves smoothly, a set of three roller-shaped carriers 4 are placed in a horizontal position in the center of the belt 3, and in a diagonal position with raised outer sides on both sides of the belt 3. In condition, belt 3
Multiple sets are installed at a fixed pitch so that they are in contact with the

In that case, a support is required to support the enclosing carrier, but conventionally, these supports 5, 7 completely surround the enclosing carrier 4 in a box shape, as shown in FIG. It was structured like this. And the inside of the lower bottom support 6 is
It protruded inward from the inner surface of the vertical support 5. Further, the upper ends of the two vertical supports 5 that are parallel to the support shaft 4a of the holding carrier 4 are both connected to the support shaft 4a.
It was located at a higher position than the department. 7 is the support shaft 4a
This is a lateral support that supported the

In these conveyors, the raw material may spill out from both sides of the belt 3 and fall, but when the raw material falls from the belt 3, the raw material passes through the inside of the vertical support 5 and falls down. However, it was deposited on the inner part of the bottom support 6. Therefore, if the conveyor is operated for a long time, the holding carrier 4 will become jammed due to the material that has accumulated high on the bottom support 6 inside the vertical support 5, and the conveyor will not rotate smoothly. Situations often occurred in which the flow of the belt 3 was obstructed.

Furthermore, when replacing the holding carrier 4, in the conventional support configuration shown in FIG. It is necessary to lift the carrier 4 up a large distance, and therefore, it is also necessary to remove the skirt part 1 of the chute as shown in FIG. The drawback was that it took a long time.

The present invention was developed in order to eliminate the above-mentioned drawbacks of the conventional technology, and is designed to prevent the carrier from becoming jammed due to the accumulation of raw materials, and to facilitate the replacement of the carrier. The purpose of this project is to provide a raw material transportation device that provides

With this configuration, when the carrier is lifted slightly and the carrier shaft is separated from the horizontal support, the bottom of the carrier will be higher than the upper edge of the vertical support, so by holding it horizontally, the carrier will move laterally. Can be moved. In addition, even if transported items that overflow from the belt or adhered to the back side of the belt fall into the box-shaped support, the transported items will not accumulate and will pass downward as there is no internal overhang. .

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

FIGS. 2 and 3 illustrate one embodiment of the present invention. In Fig. 2, the reference numeral 1 indicates the skirt portion of the chute.A skirt rubber 2 is attached to the lower end of the skirt portion 1, and the lower end of the skirt rubber 2 is connected to the belt 3 of the conveyor.
is in contact with the top surface of

In the figure, the reference numeral 4 indicates a holding carrier, and this holding carrier 4 is connected to vertical supports 5a and 5b shown in FIG. 3 via a support shaft 4a.
It is rotatably supported by a support 7a between. Further, as shown in FIG. 3, the holding carrier 4 has a roller shape and is configured to be in contact with the belt 3 so that the belt 3 can freely move in parallel. What is indicated by numeral 8 is a pedestal.

The improvements of this embodiment shown in FIG. 3 over the conventional example shown in FIG. 1 are as follows.

In this embodiment shown in FIG. 3, a lower bottom support 6a supporting vertical supports 5a and 5b,
The inside of 6b does not have a structure in which it protrudes toward the holding carrier 4 side as in the conventional example shown in FIG. The support structure or welded structure is used to prevent raw materials from accumulating in the supports 5a and 5b. In addition, the holding carrier 4 and supports 5a, 5b
The distance W between the
For example, larger than the radius of the enclosing carrier 4, 80
~100mm.

Further, the support 5b is configured such that its upper end is lower than the position of the support shaft 4a supported by the horizontal support 7a, and the upper surface of the support 7a and the support shaft 4a are
The sinking dimension A of the holding carrier 4, which is the distance between the lower surface of the holding carrier 4, and the dimension B between the lower end of the holding carrier 4 and the upper end of the support 5b are B=A-(0 to 10
mm). This means that when removing the holding carrier 4, if the holding carrier 4 is lifted and the support shaft 4a is moved even slightly above the upper surface of the horizontal support 7a, the holding carrier will be horizontally moved in the direction of the vertical support 5b. , so that it can be taken out as is without hitting the vertical support 5b. In short, the holding carrier 4 can be taken out by simply lifting it up a little.

Since the present embodiment is configured as described above, all the raw materials falling from the conveyor 3 fall downward without being caught by the bottom support 6a, and as a result, the holding carrier 4 The effect of not causing biting can be obtained.

Furthermore, by reducing the height of at least one of the vertical supports 5a and 5b and taking the dimensions A and B shown in FIG. 3 as described above, when replacing the holding carrier 4, The holding carrier 4 can be easily removed with the minimum dimension A that allows it to be removed. Therefore, when replacing the holding carrier 4, there is no need to lift the holding carrier 4 higher than necessary, so it is only necessary to remove the skirt rubber 2 and lift the conveyor 3 slightly, which is much easier than before. , it is possible to obtain the effect that the trouble of removal can be significantly reduced. Of course, the same applies when attaching the holding carrier 4.

In addition, in this embodiment, although the height of the vertical support 5b is lowered, the height of the other vertical support 5b is reduced instead.
Either lower the height of a or use vertical support 5
The heights of both a and 5b may be reduced. That is, at least one of the vertical supports 5a and 5b parallel to the support shaft 4a of the holding carrier 4 may be set low.

Of course, the present invention can be used in a holding carrier section other than the raw material loading section, and can also be used as a support device for a normal belt conveyor.

As is clear from the above description, according to the present invention, since the structure is as described in the claims for utility model registration, not only can only the carrier roller itself be attached and detached from the box-shaped support extremely easily,
It is possible to eliminate the disadvantage that objects falling from the belt accumulate in the box-shaped support and impede smooth rotation of the carrier.
