SJ-100型自走式烟草上房机的设计与试验

Design and experiment of SJ-100 self-propelled tobacco lifting machine

为实现烟草上房烘烤时烟草顺利提取、输送、有序摆放,减轻劳动强度,设计研制了SJ-100型自走式烟草上房机。该机包括行走装置、提取装置、升降输送装置、摆放装置。行走装置为电机前驱后轮转向的四轮底盘,兼具良好的操作性能和通过性能;提取装置和摆放装置均采用双平行四边形机构,可在上下升降和前后推送摆放过程中始终保持烟草平衡状态。工作时,提取装置提取烟草后,经升降输送装置移动到摆放装置,并在烤房上摆放。试验结果表明,作业过程中烟草提取平稳且提取力足,输送顺畅,摆放整齐有序,测得行走速度3.11 m/s,单次提取质量150 kg,输送速度0.2 m/s,净升降输送高度1.9 m,作业质量满足烤房布局要求和作业要求。

Aiming at achieving that tobacco was extracted, transported and ordered in an orderly manner and reducing labor intensity. the SJ-100 self-propelled tobacco lifting tobacco was designed. The tobacco lifting machine mainly composed of walking device,lifting device, delivering device and putting device. A four-wheel chassis of the motor drive and the rear wheel steering was used as walking device to achieve good performance of passing and operating. Both the lifting device and the putting device adopt the double parallelogram mechanism, which can always keep the tobacco in balance during the up-and-down lifting and the front and rear pushing. When the machine works, the tobacco on the ground was lifted from the lifting device and moved to the placement device via the lift conveyor and then placed on the grill. The test results show that the process of tobacco lifting and putting were smoothly and orderly, the walking speed was 3.11 m/s, the single lifting quality was 150 kg, the conveying speed was 0.2 m/s, the net elevating conveyor height was 1.9 m, It is shown that all working quality index can meet the requirements of the curing barn and the tobacco lifting.
