The Key Parameter Design and the Experimental Research on 4KM-1800 Trailed Cotton Straw Baling or Harvest

【Objective】 In order to get a reasonable and effective use of cotton straw.It is necessary to develop combine harvest and baling cotton machine with high recovery rate,strong bundle,and high density.【Method】Theory analysis and parameters calculation of the machine working parts structure have been proceeding based on previous forage grass baling mechanism.The optimized structure parameters of combine harvest and baling cotton machine have been determined.【Result】 Test results showed that the best performance of the machine was as follows: work speed ≥ 2 km/h,cotton straw recovery rate ≥95%,work width: 1 400-1 800 mm,productivity: 8-10 bundle/h;reliability ≥90%.【Conclusion】 The development of the models effectively solve the technical problems of a bale of cotton stalk harvesting and improve cotton stalk resources use directly.The recycling costs of the cotton straw and farmland work frequency can be greatly reduced basing on this machine.A renewable energy can be developed and cotton straw baling technology can be promoted in the future.
