| Abstract: | In view of demand of mechanized harvesting of shrub plants such as Caragana korshinskii, seabuckthorn, salix psammophila, and Amorpha fruticosa,the 9L-200 shrub harvester was developed and designed.The crawler chassis suitable for sandy land, sandy slope, hilly land and muddy land is adopted, and the quantitative hydraulic pump+proportional valve+variable travel motor is used for driving; Based on the sawing principle, a cutting and feeding header with double circular saw discs rotating inwards to cut shrubs without support is designed; Development of combined chopping drum device; By increasing or decreasing the number of moving knives and tool holders, the stepwise adjustment technology of cutting length is realized; A reverse gear box device has been installed to achieve rapid removal of blockages;According to the field inspection and field test of the National Agricultural Machinery Quality Inspection and Testing Center, the productivity of the machine is 6-10 mu/h, the material cutting length is 20-40 mm adjustable, and all performance indicators meet the design requirements, meeting the market needs of large-scale shrub flat stubble harvesting and industrial resource utilization. |
