Research on the Design and Experiment of Elevators Based on Different Types of Corn Harvesters

In order to solve the problem that the elevator of the corn harvester can realize the maximum transportation quickly and orderly when a large number of corn ears are fed, a corn harvester elevator is designed. Determine the reverse conveying mode according to the different transportation modes of the elevator, analyze the force of the ear during the conveying to determine the width of the scraper, and analyze the throwing motion after the ear is separated from the scraper to determine the vertical displacement of the ear falling into the peeling device.Then use 4 YZB-4 C and 4 YZB-6 A corn harvester elevators because they often contain broken corn stalks in the process of ear ascending, so they can be removed in different ways（4 YZB-4 C models have movable knives and fans to remove impurities, 4 YZB-Model 6 A is equipped with centrifugal fan and pulling roller to remove impurities） as the research object. The ear damage and impurity removal function of the two different corn harvester elevators during the unloading of the ears are used as the test indicators. Carry out self-made test bench test. The test results show that the elevator of the 4 YZB-6 A corn harvester with centrifugal fan is better than the elevator of the 4 YZB-4 C corn harvester in terms of impurity removal, and the ear damage is slightly higher.
