Research On The Key Parts Of The Corn Combine Reaping Both Corn Stalk And Spike

Corn is one of three major grain crops in our country,which also the high-quality raw material for livestock industry.With the development of agriculture mechanization and the development of stock raising,the corn combine reaping both corn stalk and spike is becoming a hotspot.It can harvest corn ear and stalks,at the same time,it can chop corn stalks.It reduces the recycling process and solves the problem of the development of animal husbandry.Firstly,the essay definite the program of the knapsack of corn combine reaping both corn through theoretical analysis,the collection part of corn ear adopts combination of stalk pulled roller.The gathering part of stalk adopts collection system which is made of reciprocating type cutter to cut off stalks,conveyor box of auger,double-layer floating rollers convey stalks,chopping and throwing of disc cutter shredding machine.In order to adapt various working condition and pattern,the machine is designed with two separated lift cutting workbench which can work independently,to realize harvesting corn ear and stem.Second,the essay is focus on the details design of stalk collection,fix structure,layout and parameters of rotor cutting by analyzing and calculation,with low vibration,uniformly forced and cutting stem.Four feeding-rollers with different diameter and tooth form make stalks ordered,and delivery its to the rear of the machine,then the chopper cut off them and tossed to the field.This article established the three-dimensional model of the disc shredder,and matching knife modal analysis using ANSYS to determine the design is reasonable.Thirdly,the essay is focus on the details design of disc shredder.The shredder is a high-speed moving parts,in order to avoid the occurrence of the phenomenon of resonance in the shredding process.This article established the three-dimensional model of the disc shredder,and matching knife modal analysis using ANSYS to determine the design is reasonable.Finally,in order to verify the performance of the knapsack of corn combine reaping both corn,we conducted a field experiment in the experimental field.Experiments show that the structure of the machine is reasonable,the performance of the harvester have reached the design requirements of the mission statement and consistent with national standards.
