在玉米脱粒旺季,自制一架手摇玉米脱粒机,可使脱粒速度增快几十倍,而且脱出的玉米不破、不碎,玉米棒与玉米粒又不掺杂在一起。这种手摇玉米脱粒机的制作十分简便,且又经济,其制作方法是:用“312”轴承一盘(内径为6厘米),在轴承内壁焊接上6只高1.5厘米、厚0.4厘米、长与轴承厚度相等的铁“牙齿”,并在内壁焊接一钢筋摇柄,然后在轴承外壁焊接一块“(?)”形铁板,下端安上两只螺丝。在使用时,把“(?)”形铁板卡在条凳边上,用下端的铁丝固定。然后右手摇转轴承,左手把玉米棒塞入带齿的轴承中,就可以脱粒了。
In the corn threshing season, homemade a hand-cranked corn thresher, threshing speed can make dozens of times faster, and prolapse of the corn is not broken, not broken, corn cob and corn do not doubly together. This hand-cranked corn thresher production is very simple and economical, its production method is: With a “312” bearing a (6 cm inner diameter), the inner wall of the bearing welded 6 high 1.5 cm, 0.4 cm thick, Length of the bearing with the same thickness of iron “teeth”, and welded in the inner wall of a steel handle, and then welded to the outer wall of a “(?)” Iron, the bottom of the two screws. In use, the “(?)” Iron stuck in the bar stool, with the lower wire fixed. Then roll your right hand bearing, the left hand into the corn cob gear bearing, you can threshing.
