Further, the tail end of the connecting edge and the attaching end face of the spoke are arranged in the same plane.
Further, the joint end surfaces of the two groups of spokes are tightly attached, at least 12 welding spots are arranged, and the welding spot ring rows are uniformly distributed on the edges of the joint end surfaces.
Further, a central hole is formed in the center of the spoke, and the combined spinning belt pulley is installed on the main shaft of the agricultural machine through the central hole.
Further, the edge of the center hole is provided with assembly holes, the assembly holes are provided with a plurality of groups, and the annular rows are uniformly distributed on the circumferential surface of the center hole.
Further, the fitting holes are provided with 6 groups.
Compared with the prior art, the utility model has the following advantages:
the two groups of single-groove belt pulleys are welded to form the large-diameter combined spinning belt pulley, so that the production is convenient, and the process is simple. And the spoke positions of the two groups of single-groove belt pulleys adopt an electric welding mode of at least 12 points, and the joint of the V-shaped grooves adopts circumferential laser welding, so that the strength of the spoke and the belt pulleys is increased, and the deformation generated in use is reduced.

Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in figures 1-2, the large-diameter double-wheel combined spinning belt pulley is mainly used for meeting the functional requirements of agricultural machine belt pulley transmission. The combined spinning belt pulley disclosed by the utility model is formed by manufacturing a 2mm steel plate, spinning and folding a large-diameter single-groove belt pulley 100 with triangular grooves, and then welding two groups of single-groove belt pulleys 100.
Specifically, the single groove pulley 100 includes a spoke 110, the rim of the spoke 110 is folded by a spinning process to form a V-groove 120, and the outer rim of the V-groove 120 is provided with a connecting edge 121. The distal end of the connecting edge 121 and the abutting end face of the spoke 110 are disposed in the same plane. The connecting edges 121 of the two sets of single-groove pulleys 100 are attached to each other, and the spokes 110 are also attached to each other. The spokes 110 and the V-grooves 120 are welded and fixed by a welding process, respectively, to form a combined spinning pulley.
The joint end surfaces of the two groups of spokes 110 are tightly attached, at least 12 welding spots are arranged, and the welding spot ring rows are uniformly distributed on the edges of the joint end surfaces. The strength of the spoke 100 is increased, and the joint of the two V-shaped grooves 120 is welded by adopting circumferential laser to increase the strength of the belt pulley, so that the same rigidity of the casting is achieved.
The center of the spoke 110 is provided with a center hole 111, and the combined spinning pulley is mounted on the main shaft of the agricultural machine through the center hole 111. The edge of the central hole 111 is provided with an assembly hole 112, the assembly hole 112 is provided with a plurality of groups, and the annular rows are uniformly distributed on the circumferential surface of the central hole 111. The fitting holes 112 are provided with 6 groups. Small holes are also distributed on the edge of the central hole 111.
Specifically, the two single groove pulleys 100 are spot welded after pre-punched to ensure concentricity of the two pulleys. After spot welding, the assembly holes 112 and the central holes 111 are punched, and the two wheels are symmetrically combined together to increase the rigidity of the pulley groove and reduce deformation in use. The belt pulley large-diameter belt pulley of the product has high strength, can bear severe working environment, and is widely applied to agricultural machinery transmission belt pulleys.
The product has the characteristics of novel product design, high strength, high processing precision, light structure, high assembly efficiency, long service life of the product and the like, and changes the cast iron belt pulley into a rotary pressure high-strength double-groove belt pulley, thereby producing good economic benefit and having very wide application prospect.
