Technical Field

The invention relates to the technical field of agricultural machine belts, in particular to a flexing-resistant cloth-wrapped agricultural machine belt.

Background

In recent years, agricultural machinery and equipment in China are rapidly developed, and particularly, after the original manual harvesting of corn peanuts in the north is changed into mechanical harvesting, the requirements of the agricultural machinery and equipment are greatly increased. The agricultural machine belt is the main driving medium of agricultural machine equipment, and compared with the common wrapping cloth belt, the agricultural machine belt has the advantages of large ratio of top width to thickness, thinner belt body and lower bending stress. The quality of the agricultural machine belt determines the harvesting quality and efficiency of the harvester, the cloth-coated agricultural machine belt has better wear resistance but inferior flexing performance to that of the cutting belt, and in order to prevent the agricultural machine belt from being damaged in the receiving season and causing economic loss, a part of the harvesters often select a foreign cloth-coated agricultural machine belt which is very high in price.

The foreign cloth-covered agricultural belt usually uses wide-angle cloth as a cloth-covering layer to improve the flexibility of the agricultural belt, the wide-angle cloth is expensive, the warp and weft angles of the wide-angle cloth are 120 degrees, the cost is high, and the flexibility resistance is general, so the improvement is needed.

Disclosure of Invention

In view of the above, the invention aims to provide a flexing-resistant cloth-wrapping agricultural machine belt.

In order to solve the technical problems, the technical scheme of the invention is as follows:

resistant inflection infantees machine area is including the area body to and the infantees layer of cladding in the area body outside, the infantees layer includes two-layer cord fabric, and wherein two-layer cord fabric alternately infantees, and the crossing angle of two-layer cord fabric is 150.

Further, the belt body is sequentially provided with a fiber chloroprene rubber layer, a fiber-free chloroprene buffer rubber layer, a chloroprene rubber cement layer, a fiber-free chloroprene buffer rubber layer and a fiber-containing chloroprene rubber layer from top to bottom; wherein the chloroprene rubber cement layer is internally provided with a plurality of cords with length directions arranged along the belt body transmission direction.

Further, the cord is an aramid cord.

Further, the belt body also comprises a cord fabric layer arranged at the lowest part; wherein the cord direction of the cord fabric layer is perpendicular to the transmission direction of the belt body.

Further, the cord fabric comprises two layers.

Furthermore, in the chloroprene rubber layer with fibers, the length direction of the fibers in the chloroprene rubber layer with fibers is vertical to the transmission direction of the belt body.

Compared with the prior art, the invention has the advantages that:

according to the agricultural machinery cotton-covered belt, the cord fabric is adopted to replace the traditional wide-angle fabric to serve as the cloth wrapping layer, the crossing angle of the two layers of cord fabrics is set to be 150 degrees, so that the cost can be reduced, the bending stress is lower compared with that of 120 degrees when the two layers of cord fabrics are crossed to be 150 degrees, the transverse rigidity and the flexibility of the agricultural machinery cotton-covered belt are improved to the maximum extent, and the service life of the agricultural machinery belt is greatly prolonged.
