[0027] An air outlet is formed on the side of the reject frame 3 away from the blast box 65. A discharge frame 67 is fixedly arranged in the air outlet. The bottom of the air inlet frame 66 and the bottom of the discharge frame 67 are flush with the top of the containing frame 62, which facilitates the blowing of the poor quality seeds in the pumpkin seeds on the containing frame 62 through the discharge frame 67. A rotating shaft 63 is arranged through the containing frame 62. The front and rear ends of the rotating shaft 63 are connected to the front and rear sides of the fixed frame 61 through bearings.

[0028] A motor 64 is fixedly arranged on the rear side of the reject frame 3. The output shaft of the motor 64 penetrates the reject frame 3 and the fixed frame 61 and is fixedly connected to the rear end of the rotating shaft 63, which facilitates the rotation of the rotating shaft 63 driven by the motor 64 and the overturning of the containing frame 62. The screening machine body 2 is fixedly provided with a control panel 8 on the side away from the reject frame 3 for controlling the operation of the motor 64 and the blast box 65.

[0029] By arranging the reject assembly 6, the operation of the control panel 8 controls the operation of the blast box 65. The blast box 65 blows air into the reject frame 3 through the air inlet frame 66. Then, the pumpkin seeds to be screened are poured into the feeding frame 4 and gradually fall between the two limiting tables 10 into the containing frame 62. In the process of falling of the pumpkin seeds, the air blowing through the air inlet frame 66 can blow out the poor quality seeds in the pumpkin seeds and the impurities and dust contained in the pumpkin seeds through the discharge frame 67, thereby realizing the rejection of the poor quality seeds and avoiding the mixing of the poor quality seeds with the high-quality seeds, which leads to the decline of the screening quality.
