Design and Virtual Experiment of Shunt Type Electromagnetic Vibration Seeding Apparatus for Rice Direct Seeding Machine

Abstract

The 2BD-8 self-propelled shunt type rice direct seeding machine is equipped with a shunt plateaccording to the seeding amount. It has good working performance and high efficiency. Usingit for mechanized direct seeding rice production can achieve the purpose of saving labor, time,energy and high yield. However, the machine has a large width, large running resistance, andserious mud retention, and the machine is matched with the original rice transplanter head, sothe high cost is not conducive to popularization. Therefore, it has been improved and designed.The eight-row machine is changed to a six-row machine to reduce the width of the wholemachine. It is used with a 6-horsepower walking tractor to reduce costs and is suitable for usein southern small fields. This study also conducted a virtual test on the designed shuntelectromagnetic vibration seeding apparatus. The test results show that the force of the seedwhen traveling on the seed plate is reasonable; the forward speed is 21.7mm/s ,which meets therequirements of agronomy for the seeding speed; the throwing index of the seed on the seedplate is 0.4 less than 1, so the seed slides on the seed plate. The virtual simulation test resultsare basically consistent with the theoretical calculation results, and the design is reasonable.
