ABSTRACT

At the time the corn is harvested ,the labor force of corn’s clothes taked-off by hand is very strong, wasting time and decreasing the quantity of the corn.To solve the problem of corn’s clothes taked-off that is of great importance 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 takes off the corn’s clothes ,which has four types ,respectively meets the demand of single ,union of several and big harvest.The machine takes the place of the traditional handed-labor,reducing people’s labor strength,increasing the efficiency and preventing the corn’s damage.The structure of the machine is simple and the machine is easily adopted,reliable and of high efficient.The power of the machine can use electric motor、desel engine and the engine of three-wheeled agricultural car.This machine adopt the alternate current as the motives.The cylinder of the taked-off list is consisted of spiral iron cylinder and rubber cylinder.The spiral iron has some hurt to the seed of the corn.So this machine adopt the whole rubber cylinder.This machine is designed under the premise that must be get to 95% of taked-off rate and efficiency required no less than 1500kh/h,power no more than 3kw.To get to these requirements ,main taked-off part makes use of rubber cylinder ,and they are installed up-down.The machine can adjust the distance between the two cylinder according to the size of the corn and is more reasonable than the way of traditional design in structure.After calculation and check ,the machine meets the demand of design,and makes some improvements in the corn’s taked-off list and the way of transmission system,comparing with the traditional design.Worthwhile,it is widely applied in rural.
