The inner side of the cooling air box 1 is evenly fixedly connected with a guide plate 9, the front end of the cooling air box 1 is fixedly connected with a guide air bin 10, and the bottom end of the guide air bin 10 is symmetrically fixedly installed with a heat dissipation fan 13. The heat dissipation fan 13 transports air into the interior of the guide air bin 10. The arc design of the guide air bin 10 makes the air flow to the interior of the cooling air box 1. The bottom end of the cooling air box 1 is symmetrically fixed. It is connected to two supporting cross bars 7, and both ends of the top of the supporting cross bars 7 are respectively penetrated with movable plug-in slots 8. The middle part of the bottom end of the cooling air box 1 is rotatably connected to the transmission shaft 14, and the two ends of the transmission shaft 14 are respectively fixedly connected to the eccentric wheels 15. The rotation of the eccentric wheel 15 can generate vibration, thereby driving the cooling air box 1 and the grain cooling screen 2 to vibrate, so that the grain is evenly diffused and cooled faster. The eccentric wheels 15 are distributed on both sides of the cooling air box 1, and a servo motor 5 is fixedly installed on the top of the motor support frame 4. The driving end of the servo motor 5 is softly connected to one end of the transmission shaft 14.

The air circulation through the breathable heat dissipation screen 16 improves the heat dissipation effect of the grain. The grain cooling screen 2 is arranged at the top of the cooling air box 1, and the mounting side plates 18 are fixedly installed on the outside of the cooling air box 1.
[0023] The top of the vibration bracket 3 is fixedly installed with a top anti-slip plate 6, the inner side of the vibration bracket 3 is evenly fixedly connected to the limit rod 11, the outer side of the limit rod 11 is nested with a vibration spring 12, the top of the vibration bracket 3 is movably inserted into the inner side of the movable plug-in slot 8, so that the shaking transmission shaft 14 drives the cooling air box 1 to vibrate up and down, the bottom end of the supporting cross bar 7 is evenly provided with a limit rod identical to the limit rod 11, the top of the vibration spring 12 is movably inserted into the outer side of the limit rod at the bottom end of the supporting cross bar 7, and the vibration spring 12 is limited by the limit rod 11 and the limit rod at the bottom end of the supporting cross bar 7 to prevent the vibration spring 12 from detaching due to vibration.
[0024] The front end of the guide air bin 10 is designed in an arc shape, which allows the air to flow more smoothly into the interior of the cooling air box 1. The inner side of the tail end of the cooling air box 1 is designed in an arc shape, which allows the flowing air to turn upward and be transported to the interior of the grain cooling screen 2. The top end of the guide plate 9 is inclined toward the tail end of the cooling air box 1.

Since the top end of the vibration bracket 3 is plugged into the inner side of the movable plug-in slot 8, the shaking transmission shaft 14 drives the cooling air box 1 to vibrate up and down. The vibration of the cooling air box 1 drives the grain cooling screen 2 to vibrate continuously, and the cooling fan 13 delivers air into the interior of the guide air bin 10, through The arc-shaped design of the guide air bin 10 allows the air to flow into the interior of the cooling air box 1, and the air is guided by the guide plate 9 to flow upward at an angle, enter the interior of the grain cooling screen 2 through the heat dissipation screen 16 at the bottom end of the grain cooling screen 2 and be discharged through the heat dissipation screen 16 at the top end of the grain cooling screen 2, and then the dried grain is poured into the interior of the grain cooling screen 2 through the material receiving end 17.
