Parameter design and optimization of white celery screw congestion device
In order to solve the problem of uneven soil distribution in the developed ridge-three row parsley machine,the working process of the machine was analyzed and simulated based on the discrete element theory.The influence of each factor on the uniformity of soil distribution was analyzed by taking the rotation speed,pitch of the helicoid in the helical soil feeding device and the angle of the feeding port of the soil forming die as experimental factors.A three-factor and three-level combination experiment was designed,and the parameter combination of the model was optimized and solved,and the optimal parameter combination of soil uniform distribution was obtained as follows:the spiral rotation speed was 180 r/min,the spiral pitch was 200 mm,and the feeding angle of the soil forming mold was 63°.Field experiments were carried out on the optimized screw soil feeding device on an earner.The results showed that the soil in four ridges was uniform and formed in accordance with the requirements of earthen cultivation,which improved the efficiency of earthen cultivation and met the requirements of three rows of parsley planting mode on four ridges.
