DETAILED DESCRIPTION

[0016] The utility model will be further explained in connection with the drawings.

[0017] As Figure 1 , Figure 2 , Figure 3The shown corn selection device includes a box 1, a feeding conveyor belt 2, and a discharging conveyor belt 4. The box 1 has a feeding port on one side and a discharging port on the other side. The feeding conveyor belt 2 is fixedly connected to the box 1 through the feeding port. The discharging conveyor belt 4 is fixedly connected to the box 1 through the discharging port. The discharging conveyor belt 4 is provided with a support at the bottom. The support is arranged on the working surface through the bottom of the box 1. The box 1 is provided with a support plate 5 fixedly connected to the inside of the box 1. The support plate 5 is provided with a plurality of selection tables 6 fixedly connected thereto. The selection tables 6 are provided with trapezoidal grooves.
