Chaff cutter chaff use and maintenance as a more dangerous products, in the use and maintenance of the user should be taken seriously enough, as follows: 1, should familiar with before starting the manual, according to the provisions and adjustments maintenance, check the fasteners are tightened, the blade rotation direction is the same predetermined direction, such as locking bolts on the chassis. 2, according to the requirements of the instruction manual, gear often butter filling, non-dry grinding, guillotine cut every time, oiling once. 3, chaff workplace should be spacious, have a reliable fire-fighting equipment. 4, under instructions of the appropriate choice of matching motor, allowed to increase the spindle speed when using chaff price, not allowed to freely tear down the protective cover; the job may not use sticks, iron bars forced feeding. 5, the replacement of moving and stationary blade when tightening bolts, high strength bolts must not be replaced with ordinary fasteners. 6. An exception occurs when the job should immediately stop inspection chaff, prohibit troubleshooting when the machine is running. 7, moving, keep sharp fixed knife. 8, when the chaff disabled machine manufacturer, should wipe the surface dust and stolen goods, in the open air should pay attention to rain, moisture and prevent rust. Fixed blade as a main component 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 agricultural chaff cutter, identified carburizing layer thickness of 0.3mm, 0.6mm and 0.9mm at optimal carburizing temperature is 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 .
