Fuente: WIPO "industrial hemp" The utility model relates to the field of industrial hemp breeding, in particular to a multifunctional pollen collecting device for industrial hemp breeding, which comprises a box body, a sieve plate is arranged on the inner wall of the box body through a frame, connecting rods are rotatably connected to the top end of the frame, eccentric rods are rotatably connected to the other ends of the two connecting rods, and discs are fixed to the outer ends of the two eccentric rods. Horizontal round rods are fixed to the two discs, the other ends of the two round rods are in transmission connection with rotating rods, and the same motor is in transmission connection between the two rotating rods. The rotary rods, the round rods, the discs and the like are additionally arranged, the motor is started to drive the rotary rods on the two sides to rotate, then the round rods on the two sides can be driven to rotate, then the two discs are driven to rotate, under the action of the connecting rods, the frame and the sieve plate are driven to move in a reciprocating mode in the vertical direction, flower spikes on the sieve plate are toggled, and pollen can fall into the collecting box easily; and the shaking sieve plate is effectively prevented from being blocked.
