Description

Technical Field

[0001] The present application belongs to the technical field of pulp aramid agricultural machinery belts, and specifically relates to a pulp aramid agricultural machinery belt with a meridian cord structure. Background Art

[0002] Agricultural machinery belts refer to transmission belts used in agricultural, horticultural and forestry equipment. Their varieties and specifications include almost all V-belts and a small number of flat belts and special-shaped belts. The most important of these is the continuously variable speed belt used in combine harvesters.

[0003] Aramid pulp is obtained by surface fibrillation treatment of aramid fibers. Its unique surface structure greatly improves the adhesion of the mixture, making it very suitable as a reinforcing fiber for use in friction and sealing products.

[0004] However, the base adhesive of existing pulp aramid agricultural machinery belts often breaks during use, which affects the overall service life of the agricultural machinery belts and reduces their use efficiency. Utility Model Content

[0005] The purpose of this application is to provide a pulp aramid agricultural machinery belt with a radial cord structure in order to solve the problem that the base glue of the existing pulp aramid agricultural machinery belt mentioned above often breaks during use, affecting the overall service life of the V-belt and reducing the use efficiency.

[0006] The technical solution adopted in this application is as follows: a pulp aramid agricultural machinery belt with a radial cord structure, comprising a pulp aramid agricultural machinery belt main body, the upper end of the pulp aramid agricultural machinery belt main body is provided with a high wear-resistant fiber top rubber layer, the lower end of the high wear-resistant fiber top rubber layer is provided with a radial cord layer, the lower end of the radial cord layer is provided with a high modulus low shrinkage hard wire layer, the lower end of the high modulus low shrinkage hard wire layer is provided with a high wear-resistant fiber bottom rubber layer, and the lower end of the high wear-resistant fiber bottom rubber layer is provided with an anti-cracking cloth.

[0007] By adopting the above technical solution and the above design, the risk of breakage of the high-wear-resistant fiber base rubber layer is reduced, the service life of the pulp aramid agricultural machinery belt body is extended, and the utilization efficiency is improved.

[0008] In a preferred embodiment, a strength layer is provided at the upper end of the radial cord layer, a radial cord is provided at the lower end of the strength layer, a cord glue is provided at the lower end of the radial cord, and an adhesive glue is provided at the lower end of the cord glue.

[0009] By adopting the above technical solution, the strength layer provides the main lateral stiffness for the pulp aramid agricultural machinery belt body, so that the pulp aramid agricultural machinery belt body can maintain good shape stability during operation and prevent it from excessive deformation. The radial cord improves the load capacity of the pulp aramid agricultural machinery belt body, minimizes the circumferential bending stress of the pulp aramid agricultural machinery belt body, and reduces the risk of cracking and damage. The cord glue tightly bonds the radial cords together to form an integral cord layer, ensuring that the relative positions of the cords are fixed and work together to effectively transmit power. The adhesive glue firmly bonds the cord structure to other components to ensure the integrity and stability of the entire pulp aramid agricultural machinery belt body, and prevents delamination, peeling and other phenomena during use.

[0010] In a preferred embodiment, the upper surface of the high wear-resistant fiber base rubber layer is sprayed with a protective coating.

[0011] By adopting the above technical solution, it has excellent chemical corrosion resistance, can effectively prevent the erosion of chemical substances such as fertilizers, pesticides, oil stains, etc. on the high wear-resistant fiber base rubber layer, reduce the risk of cracking and damage, and extend the service life of the pulp aramid agricultural machinery belt body.

[0012] In a preferred embodiment, the main material of the high wear-resistant fiber top rubber layer and the high wear-resistant fiber bottom rubber layer is EPDM rubber.

[0013] By adopting the above technical scheme, it has high-strength transmission, lateral rigidity, wear resistance, high temperature resistance and bending resistance. It can effectively resist external friction, wear and high temperature influences during the transmission process of the pulp aramid agricultural machinery belt main body, protect the internal structure of the pulp aramid agricultural machinery belt main body, and at the same time, reduce the friction and wear between the high-wear-resistant fiber bottom rubber layer and other components, prevent the high-wear-resistant fiber bottom rubber layer from breaking, and extend the service life of the pulp aramid agricultural machinery belt main body.

[0014] In a preferred embodiment, the radial cords are aramid cords, which are arranged at an angle of approximately 90° to the tread centerline.

[0015] By adopting the above-mentioned technical solution, this arrangement method enables the cord to better withstand the circumferential tension generated by the pulp aramid agricultural machinery belt body during the transmission process, thereby improving the load capacity of the pulp aramid agricultural machinery belt body. At the same time, it also minimizes the circumferential bending stress of the pulp aramid agricultural machinery belt body, reducing the risk of cracking and damage.

[0016] In a preferred embodiment, the adhesive is made of chloroprene rubber.

[0017] By adopting the above technical solution, it has good viscosity, aging resistance and chemical corrosion resistance, so that it has good adhesion to a variety of materials, can effectively bond the curtain structure with other components, and improve stability.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0019] In this application, the design of the overall structure of the pulp aramid agricultural machinery belt body reduces the risk of breakage of the high-wear-resistant fiber base rubber layer, maintains stable performance, and extends the service life of the pulp aramid agricultural machinery belt body. At the same time, it also strengthens power transmission, reduces slippage, ensures operation accuracy and efficiency, and improves safety during work. BRIEF DESCRIPTION OF THE DRAWINGS
