对新设计的玉米收获机伸缩式拨禾轮进行了试验，通过单拨禾装置试验研究得出：在该拨禾轮（无分禾器）的作用下，拨禾半径由无伸缩齿的50mm扩大到125mm；通过双拨禾装置试验研究得出：拨禾范围由无伸缩齿的170mm扩大到320mm，实现了拨禾区域的扩大。同时，得出了在喂入速度为0．7m/s、摘穗辊转速为800r/min的情况下，较优喂入半径（分别以两拨禾装置的中心计算）为40～120mm。

The test with the telescopic reel of the corn harvester show that the sphere of the telescopic reel extends to 125 mm from 50 mm with single telescopic reel and the sphere of the telescopic reel extends to 320 mm from 170 mm with double telescopic reel .The expansion of the sphere of the telescopic reel comes true .In the meantime we find that the best radius of the feeding is about from 40 mm to 120 mm which is based on the center of the two devices when the speed of the feeding is 0.7m/s , the speed of the stripper roller is 800r/min.
