    • Objective 

      To explore the feasibility of sugarcane vertical clamping-conveying technology for the whole stalk harvester, and provide a technical support for solving the problem of long sugarcane channel and low working efficiency of the existing stalk-type sugarcane combine harvester.

      Method 

      A kind of vertical stripper was designed in a clamping-conveying channel for 4ZZX-48 sugarcane harvester . A harvesting test of this device was conducted in field. The influence factors of leaf stripping effect were analyzed, including the rotation rate of conveyor chain sprocket(n1), the installation angle of leaf stripping roller(β), the rotation rate of leaf stripping roller(n2) and sugarcane feeding speed(q)

      Result 

      The values of n1 and n2 had significant impact on leaf stripping effect. The ranking of influence was n1>n2>q>β. When n1 was 60 r/min , n2 was 360 r/min , β was 30° and q was 7.5 kg/s, the machine got the best stripping effect and leaf stripping rate was 76.6%. The results of curve regression analysis showed that there was a quadratic polynomial relation between clearing rate and the ratio of n2 to n1. When the value of n2/n1 ranged from 5 to 6, clearing rate reached the maximum of around 77%.

      Cluclusion 

      This harvester, based on sugarcane vertical clamping-conveying and stripping technology, is feasible and has certain reference value for research and development of a new whole stalk sugarcane harvester.
