Design of the Corn straw counters-field

Abstract

In recent years with the corn yield significant enhancement of straw, root, the increasing number of crop also. The resulting problems is clean up straw, follow chi, became farmers sow the land before headaches. As for work, when does not affect to prepare for the progress of the straw stalk, some farmers had to local burned. Do so just a waste of resources and environmental pollution. We can put it to pieces after the stalks strewn in the field, the environmental protection can alter the soil physicochemical. Corn straw chopper drive is one such farm implements. This design uses shock-free laws are arranged in knife edge, the work by the tractor by way of farming after the suspension.
