BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a conveyor structure in which a core is enclosed in a conveyor structure and the core includes rope and cloth.

2. Description of the Related Art

A conventional conveyor for an agricultural machine can use a composite belt formed by rubber and fiber cloth, instead of a chain, for power transmission. However, as shown in FIGS. 1 and 2, a core structure layer 200 disposed inside the widely used conventional conveyor structure may be exposed to the outside environment, and subsequently may be directly affected by water, vapor, or external objects easily.

Furthermore, the widely used conventional conveyor structure for an agricultural machine has a core structure layer 200 formed by a chemical fiber cloth only. In this case, the conventional conveyor structure has poor flexibility, and the joint part of the core structure layer 200 is more fragile. Therefore, what is needed is to develop a conveyor structure to solve the aforementioned problems.

Please refer to FIGS. 3 to 8, which respectively are an appearance view, a schematic view, a sectional view, a schematic view of a first winding operation, and a schematic view of a second winding operation, a schematic view of a third winding operation of a conveyor structure according to an embodiment of the present invention. As shown in figures, a conveyor structure 10 includes a first conveyor structure layer 100, a core structure layer 200 and a second conveyor structure layer 300.

In this embodiment, the core structure layer 200 can be disposed on the first conveyor structure layer 100, and includes a rope layer 201, a plurality of first wefts 202, a plurality of second wefts 203 and a cloth layer 204. In an embodiment, the rope layer 201 and the cloth layer 204 include chemical fiber rope and chemical fiber cloth, respectively; and, the core structure layer 200 can combine the rope layer 201 and the cloth layer 204 to improve the durability of the core structure layer 200. For example, when one or either of the rope layer 201 and the cloth layer 204 is damaged, the other of the rope layer 201 and the cloth layer 204 can still maintain integrity of the conveyor structure 10 of the present invention. As a result, the core structure layer 200 of the present invention can provide a support force with a certain degree, unless the rope layer 201, the cloth layer 204, and the plurality of first wefts 202 and the plurality of second wefts 203, which are the reinforced assistant structure, are all damaged.

In practice, the rope layer 201 can be disposed on the first conveyor structure layer 100, and includes the plurality of warp ropes 2011. The plurality of second wefts 203 and the plurality of first wefts 202 can be obliquely intertwined with each other and wrapped on the rope layer 201, or on the cloth layer 204, or on the rope layer 201 and the cloth layer 204. The cloth layer 204 can be disposed on the rope layer 201. For example, the cloth layer 204 can be adhered on the rope layer 201. The second conveyor structure layer 300 can be disposed on the core structure layer 200. In an embodiment, the first conveyor structure layer 100 and the second conveyor structure layer 300 can include rubber.

Upon practical demand, the plurality of second wefts 203 and the plurality of first wefts 202 can be obliquely intertwined with each other and wrapped on the rope layer 201, or on the cloth layer 204. In an embodiment, the rope layer 201 can be adhered with the cloth layer 204 first, and the combined layer can be obliquely wrapped and crossed on the rope layer 201 and the cloth layer 204.

During the manufacturing process of the conveyor structure 10 of the present invention, in order to fix the shape of the rubber of the first conveyor structure layer 100 and the second conveyor structure layer 300, a sulfidation process must be performed. During the sulfidation process, the first conveyor structure layer 100 and the second conveyor structure layer 300 are applied by a pressure, and the plurality of first wefts 202 and the plurality of second wefts 203 can constrain the plurality of warp ropes 2011, or the cloth layer 204, or the plurality of warp ropes 2011 and the cloth layer 204, so as to resist compression caused by the pressure. For this reason, the plurality of first wefts 202 and the plurality of second wefts 203 are crossed each other in latitude direction during the sulfidation process. This ensures that the intensity of tear resistance in latitude direction can be enhanced and the plurality of warp ropes 2011 in longitude direction can be protected from being exposed because of compression during the sulfidation process.

In an embodiment, a width of the core structure layer 200 can be lower than that of each of the first conveyor structure layer 100 and the second conveyor structure layer 300, as shown in FIG. 3, the core structure layer 200 can be fully sandwiched between the first conveyor structure layer 100 and the second conveyor structure layer 300. Since the core structure layer 200 is not exposed to outside environment, the core structure layer 200 is not easily affected by water, vapor or external objects directly.

In an embodiment, the rope layer 201, the plurality of first wefts 202, the plurality of second wefts 203 and the cloth layer 204 can include man-made fibers, and the first conveyor structure layer 100 and the second conveyor structure layer 300 can include rubber. The extensibility of each of the rope layer 201, the plurality of first wefts 202, the plurality of second wefts 203, and the cloth layer 204 is lower than that of each of the first conveyor structure layer 100 and second conveyor structure layer 300. In this way, the first conveyor structure layer 100 and the second conveyor structure layer 300 can be supported effectively.

Please refer to FIGS. 9 and 10, which are a first schematic view and a second schematic view of a conveyor structure according to an embodiment of the present invention, respectively. In an embodiment, the conveyor structure 10 can include a plurality of convex structures 400 formed on a top surface of each of the first conveyor structure layer 100 and the second conveyor structure layer 300. The plurality of convex structures 400 are formed on the top surfaces of the first conveyor structure layer 100 and the second conveyor structure layer 300 by a cutting manner. The plurality of convex structures 400 in cooperation with gear or other power source can be used for power transmission.

In an embodiment, the conveyor structure 10 can be adapted to an agricultural machine 500, and the plurality of fastening members 501 of the agricultural machine 500 are disposed on the conveyor structure 10. Under the condition that the plurality of fastening member 501 penetrates the first conveyor structure layer 100, the core structure layer 200, and the second conveyor structure layer 300, the portions of the core structure layer 200 not penetrated by the fastening members 501 can provide a support force to the first conveyor structure layer 100 and the second conveyor structure layer 300.

In the core structure layer 200, a portion of the cloth layer 204, a portion of the warp rope 2011 of rope layer 201, portions of the second wefts 203, and portions of the first wefts 202, which are not penetrated by the fastening member 501, can provide a portion of the support force to the first conveyor structure layer 100 and the second conveyor structure layer 300, so as to maintain entire conveyor structure 10 to be stable.

Furthermore, the portion of the cloth layer 204 not penetrated by the fastening member 501 can provide a portion of the support force to the first conveyor structure layer 100 and the second conveyor structure layer 300, so that the conveyor structure 10 can be protected from being broken or damage easily because of bending force, tension or other external force.

In addition, the portions of the rope layer 201, the first wefts 202 and the second wefts 203 not penetrated by the fastening members 501 can also provide the support force to the first conveyor structure layer 100, the second conveyor structure layer 300 and the cloth layer 204, so that the cloth layer 204, the rope layer 201, the plurality of first wefts 202, and the plurality of second wefts 203 can be used to effectively improve the intensity of entire conveyor structure 10.

The present invention disclosed herein has been described by means of specific embodiments. However, numerous modifications, variations and enhancements can be made thereto by those skilled in the art without departing from the spirit and scope of the disclosure set forth in the claims.
