山东省聊城农机研究所的科研技术人员,近期研制成功了为小四轮拖拉机配套的、前置式4MCB-2型拔棉柴机。该机已通过科研鉴定,并获得国家专利。该机主要由起拔机构、扶持喂入机构、拔棉柴机构、输送机构、动力传递机构、行走机构、悬挂提升机构和机架等部分组成。起拔机构采用圆锥圆柱复合形拔辊。该拔辊前端为圆锥台,后端为圆柱,它综合了圆锥形拔辊喂入性能好和圆柱形拔辊起拔性能好的优点。这种锥柱复合形拔辊是目前辊式拔棉柴机中较理想的一种起拔器。该机针对棉柴的特殊长势具备“强制喂入、
Shandong Liaocheng Agricultural Machinery Research Institute of scientific and technical personnel, the recent successful development of a small four-wheel tractor supporting the front 4MCB-2-pulling cotton. The machine has passed scientific research appraisal, and access to national patents. This machine is mainly composed of lifting mechanism, supporting feeding mechanism, pulling cotton mechanism, conveying mechanism, power transmission mechanism, traveling mechanism, suspension lifting mechanism and rack and other components. Pull out the mechanism using tapered cylindrical composite pull. The front end of the pulling roller is a truncated cone, the rear end is a cylinder, which combines the advantages of good feeding performance of the conical pulling roller and good lifting performance of the cylindrical pulling roller. This cone-shaped composite pull rod roller pull the current pull-cotton machine in a more ideal type of puller. The machine for the special development of cotton with ”compulsory feeding,
