It wastes time and decreases the quantity of the corn. To solve the problem of corn’s clothes take-off in our country, we designed the corn’s clothes take-off machine including the structure and the technical parameter design. It is a machine that take off the corn’s clothes. It has four types, respectively for single, union of several and big harvest. The machine instead of the traditional handed labor, reduce the people’s labor strength, raise the efficiency and prevent the corn’s damage. The structure of the machine is simple. The machine is easily adopted, reiable and efficiency. The power of the machine can use electric motor、diesel engine and the power of agricultural car.This machine adoption list mutually the alternate current motive makes the motive. Peel to equip to win to peel the son of to have the spiral iron casting son of and the rubber son of to constitute generally, cast iron the son of to have severity to the seed grain to hurt, so this machine adoption the whole rubber son of. Designed under premise that must be get go 95% of take-off rate and efficiency required no less than 1500kg/h, power no more than or equality 3kw. For get to these requirements, main take-off part makes use of rubber c
