Chaff wide practicality :( i) crushed scope, including sawdust, wood shavings, twigs, wood and all kinds of crop straw, corn stalks, cotton stalks, rice husks, peanut shells, Guayang, valley stalks, wheat straw and other. (B) the product advantages, high output power is small, the production of particles can not have warm, no color, simple structure, easy to operate, a person can operate, processing a wide range of agricultural chaff cutter, chaff material from the length restriction manufacturer particle size adjustable length. (C) the wide range of applications, used in crop straw crushing process, is fodder plants, charcoal plants, straw coal plants, plant breeding and other best processing equipment. Used in many fields straw pellet fuel, pellets, biomass power generation. (Iv) advanced technology, straw grinder I plant research is energy efficient straw dedicated grinder, the main highlight of high yield, low energy consumption, low cost. Rural grinder currently used generally fail to crush the technical requirements straw chaff price, and smash up efficiency and low, if such a low crush straw is worth something too expensive and not worth the candle. And my straw shredder plant study addresses the vast rural areas is a difficult problem for many years, in order to allow users of our products have a better understanding of surface, users are welcome to come to my factory inspection. Fixed blade as a main component chaff chaff, and direct contact with the straw, the sharpness of the blade determines the chaff performance is good or bad, not only increases the wear passive consumption of steel, but also directly affect the processing quality straw . In order to improve the effective working time of the blade, to improve processing quality forage, use of local gas carburizing, quenching, tempering heat treatment process for surface hardening blades Q235: Select carburizing carburizing layer thickness and temperature and their interactions. role as the main experimental factors to the blade hardness gradient index orthogonal test, analysis of variance to determine the carburizing layer thickness of 0.3mm, 0.6mm and 0.9mm at optimal carburizing temperature was 900 ℃, 925 ℃ and 950 ℃; the blade thickness of three carburizing and 65Mn chaff cutter blade mounted on the wear test. Analyzed under different conditions blade microstructure and hardness distribution; heat deformation analysis theory put forward effective measures to prevent the deformation; after the wear test, the wear characteristics of the macroscopic analysis of the blade, the wear size, corner radius, wear quality .
