往复揉搓式花生脱壳装置研制与试验OA

Aiming at the problems of low net removal rate,high mechanical damage rate and poor variety adaptability of existing peanut shelling devices,a reciprocating kneading peanut shelling device was developed.Taking Yuhua 22 as the test object,kinematics analysis was carried out on the working principle of shelling,and the optimal design size optimiza-tion method and kinematic graphic analysis method were used to analyze and determine when the minimum shelling gap was 12mm,and the square mesh edge of the woven screen was used.When the length is 14mm,the speed of the reducer is 70r/min,and the angle between the rocker and the vertical direction is 25°,the shelling performance is better.Using the above optimal structural design parameters,the comprehensive performance test of the device was carried out.The shelling test results showed that the average dehulling rate was 98.11%,the breakage rate was 2.76%,and the germina-tion rate was 98.2%,which met the quality of peanut shelling in the industry.The fatigue damage test of the dot rubber shows that after the accumulative operation of the reciprocating peanut shelling device for 75 hours,it is no longer condu-cive to the continued shelling of peanuts and should be replaced in time.The successful trial production of the device can provide a reference for the innovative design of peanut shelling device.
