Design and Test of Air-Sieve Peanut Vine Crusher and Film Remover
In order to solve the problem that the film residue of peanut vine used as feed after the harvest of mulched pea-nuts seriously affects the health of livestock,a peanut seedling crushing and film removal machine was designed based on the physical characteristics of crushed peanut seedlings and film,which can complete the functions of feed crushing,screening and transportation,negative pressure film removal,return material transportation,discharge collection,etc.at one time.The key components of the whole machine are designed and analyzed,and the structure and working parameters of the crushing device,air screen cleaning device and other components are mainly determined.The experimental design was carried out by using Design Expert.The effects of vibrating screen frequency and fan speed on the cleaning quality of peanut seedling film residue were studied,and the working parameters of peanut seedling crushing film remover were opti-mized.The test results show that the frequency of vibrating screen and fan speed have significant effects on film removal rate and loss rate;When the optimal parameters are the vibrating screen frequency of 3.4 Hz,the rotating speed of fan 1 is 1 000 r/min the rotating speed of fan 2 is 1 350 r/min,and the rotating speed of fan 3 is 1 500 r/min,the removal rate of the peanut seedling crushing film remover is 96.8％,and the loss rate is 1 1.2％,so that the residual film in peanut seedling can be cleaned.
