Abstract

A plant seed harvesting device comprises a multi-layer net unit; the multi-layer net unit comprises collecting net, intermediate layer net and bottom layer net; the collecting net, the intermediate layer net and the bottom layer net are all plate-like structure having a plurality of meshes; the peripheral edge of the plate-like structure is a net frame, area with the meshes is net face; The collecting net, the intermediate layer net and the bottom layer net are arranged closely in the axial direction to form the multi-layer net unit; mesh sizes on the collecting net, the intermediate layer net and the bottom layer net are configured to be successively and gradually decreased; plant seeds can pass through the meshes of the collecting net; air but not plant seeds can pass through the meshes of the bottom layer net.
