Design and Test of Circular Saw Blades for Caragana Microphylla Harvesters
The caragana microphylla circular saw blade was one of the main parts of the harvester.In the process of cut-ting,the blade was stressed unevenly,and the reciprocating cutting action leaded to its easy loss.The performance and ma-terial characteristics of caragana microphylla blade were investigated,the special steel was used as blade base and plasma arc cladding as high alloy powder coatings was applied on the blade surface to obtain excellent wear resistance and strength by optimizing tooth shape and heat treatment parameters.After friction and wearing test and field harvest test of the main body,the results showed that this caragana microphylla blade had good stubble effects,and its service life was 1～2 times longer than that of the similar products.
