BACKGROUND OF THE INVENTION Conventionally, belts have been widely used as simple and efficient transmission means or conveyance means for transmitting various mechanical devices or for conveying objects. However, in factories, workshops, farms, etc. where there is a lot of dust or where particulate materials are handled, dust may adhere to the transmission surface of the belt or belt wheel, substantially increasing the outer diameter of the belt wheel. In some cases, the running speed of the belt may be changed or, in some cases, the belt may be removed from the belt pulley. This often occurs particularly when conveying powder and granular materials, and is a drawback of belt-based transmission or conveyance.

To solve this problem, attempts have been made to minimize the amount of dust or particulate matter that adheres to the belt or belt wheel by placing a scraper or brush in contact with the belt or belt wheel, but even then the operation is still sometimes stopped. In addition, as the scrapers and brushes wear out, their effectiveness gradually decreases, so they must be replaced with new ones as appropriate.In the end, there is no fundamental solution. The present invention was proposed for the purpose of preventing the adhesion of dust and particulate matter without using such scrapers or brushes, in other words, by simply devising the shape or structure of the belt and belt wheel. It is.

When the endless belt runs, the cavity maintains an airtight state between the peripheral edge of the belt sheave and the wall of the cavity in the curved running portion that is in contact with the belt sheave, and also maintains a sealed state between the left and right belt sheaves when running in a straight line. In some parts, the flexibility of the endless belt itself closes the incision and maintains a sealed state. That is, the cavity of the belt is always closed, and it is possible to prevent dust and particulate matter from entering the cavity.

The illustrated embodiment will be described in detail below. In the first embodiment shown in FIGS. 1 to 3, 1
2 is a round endless belt made of a flexible material, such as rubber or synthetic resin, or a material made by weaving reinforcing fibers into these materials; A cavity with an isosceles triangular cross section provided in the corner, the corner opposite to the base 3, that is, the apex formed by both hypotenuses coming together, coincides with the inner circumferential surface of the endless belt 1, and the cavity 2 is placed there. A notch 4 that can be opened is made in the inner peripheral surface of the endless belt 1. Although this notch 4 can be pushed open, it is normally closed by the closing force due to the flexibility of the endless belt 1 itself. Reference numerals 5 and 5 refer to belt pulleys which are mounted on shafts at required intervals on the left and right and are wound around both sides of the endless belt 1.The peripheral edge 6, which has a chevron-shaped cross section, is thrust into the cavity 2 through the above-mentioned notch 4, and the peripheral edge 6 is The end face 7 of the cavity 2 is brought into contact with the bottom side 3, and the left and right wall surfaces of the cavity 2 are brought into pressure contact with the left and right side surfaces of the peripheral edge part 6. When the endless belt 1 runs in the direction of the arrow in Figure 1,
In the part A, the peripheral edges 6 of the belt pulleys 5, 5 rush into the cavity 2 while pushing the notch 4 open, and in the part B, the notch 4 closes again. That is, the cavity 2 of the endless belt 1 maintains a sealed state between the peripheral edge 6 of the belt sheaves 5, 5 and the wall surface of the cavity 2 in the curved traveling portion where it is in contact with the belt sheaves 5, 5, and In the linear running portion between the belt pulleys 5, 5, the flexibility of the endless belt 1 itself closes the notch 4 and maintains a sealed state. Therefore, the cavity 2 is always closed, and no dust or particulate matter can enter the cavity 2. However, strictly speaking, a minute gap is created just before the peripheral edge 6 of the belt pulleys 5, 5 and the notch 4 are joined or separated from each other at the positions A and B shown in FIG. There is no risk of powder or particulate matter entering. When it is necessary to eliminate such fears,
As shown in FIG. 5 as a modification of the first embodiment,
An annular groove 8 is dug in the end surface 7 of the belt pulleys 5, 5, and the annular groove 8 and the inside 10 of the tube shaft 9 are communicated through a passage 11, and an air supply pump (not shown) prepared separately is provided. Therefore, if air is forcibly blown through the cavity 2 and ejected from each of the above-mentioned gaps, external dust and powder particles will not enter through the gaps. Next, in the second embodiment shown in FIG. 4, the present invention is applied to a flat endless belt, and like the round endless belt 1 of the first embodiment, the lower surface (or inner surface) is made of a flexible material. This is different from the first embodiment in that a bulge is integrally molded into the bulge, and a series of cavities 2 with an isosceles triangular cross section are provided along the length of the bulge. Since this is the same as the first embodiment, the same parts will be given the same numbers and the explanation will be omitted.

As is clear from the above description, in the belt transmission device of the present invention, the cavity of the endless belt is
In the curved running part that is in contact with the belt sheave, a sealed state is maintained between the peripheral edge of the belt sheave and the wall of the cavity, and in the straight running part between the left and right belt sheaves, the endless belt itself is flexible. The notch is closed by the closing force and maintained in that state. Therefore, the cavity is always closed and no dust or particulate matter can enter the cavity, so it is no longer necessary to introduce dust or particulate matter into the transmission surface between the belt and the belt pulley as in the past. There is no need to change the running speed of the belt or remove the belt from the belt pulley.
