Pollen sample collecting device

The invention relates to the technical field of agricultural tools, and provides a pollen sample collecting device which comprises a lifting rod and a sampler, the bottom of the lifting rod is fixedly connected with a conical body through a screw, and the top of the lifting rod is fixedly connected with a fixed block through a screw. A first synchronous wheel is driven by a motor to rotate, a second synchronous wheel drives a straight rod to move back and forth, a push rod is pushed to knock a flower rod, pollen falls down and is collected into the sampler through a collection opening, then a weight sensor transmits a signal to enable an electric cylinder to drive a storage box to descend, and the storage box is rotated through a square rod; and after the moving distance is rotated, the electric cylinder drives the storage box to ascend, so that the pollen is collected into other box bodies, and quantitative pollen collection is realized. By means of the technical scheme, the problems that in the prior art, q
