The invention discloses a seeder land wheel with a speed change function. According to the seeder land wheel with the speed change function, the efficiency of adjusting the seeding plant spacing during seeding in spring is effectively achieved, the use space of a seeder is saved through the combination of a gearbox and a land wheel, and therefore, the effect that the furrow width and furrow distance of the seeder are more flexibly adjusted is achieved. A joint of a land wheel support and a seeding box is concentric with a power input shaft, and the land wheel support and seeding machine angle adjusting device is arranged below, so that the height of the land wheel of the seeding machine can be conveniently adjusted while the length of an input chain of the seeding machine is not influenced. A gear falling prevention device is arranged in the gearbox, so that gear falling can be effectively prevented.

    本发明为带有变速功能的播种机地轮,有效的解决了在春季播种时调节播种株距的效率,并且通过变速箱与地轮的结合节省了播种机的使用空间,从而达到更加灵活的调节播种机隆宽,隆距的效果。地轮支架与播种箱连接处与动力输入轴同心,在下方设置有地轮支架与播种机角度调节装置,可以在不影响播种机输入链条长度的同时,方便的调节播种机地轮高度。在变速箱内部设有防掉档装置,能有效的防止掉档的发生。
