Seedling-separating device for agricultural machine

The invention provides a seedling-separating device for an agricultural machine, and relates to the field of auxiliary devices of agricultural machines. The seedling-separating device comprises one or more sub-seedling separating devices, wherein each sub-seedling separating device comprises two seedling-separating plates; a certain angle is formed between every two seedling-separating plates, and every two seedling-separating plates are intersected at the front part of the corre-sponding sub-seedling separating device; the intersection line of every two seedling-separating plates is arc-shaped, and every two seedling-separating plates are connected with the agricultural machine. The seedling-separating device for the agricultural machine is simple in structure and compact; besides, by virtue of the seedling-separating device, the traffic capacity of the agricultural machine in farmlands can be effectively improved.
