One end of the conveyor belt 4 passes through the side of the drying box 1 and extends into the feeding box 2, and the other end of the conveyor belt 4 passes through the other side of the drying box 1 and extends into the discharging box 3. The discharging box 3 is provided on the side of the drying box 1, and both ends of the conveyor belt 4 are connected to driving wheels 6. A first rotating shaft 5 is provided at the center of the driving wheel 6. One end of the first rotating shaft 5 is rotatably connected to the feeding box 2, and the other end passes through the feeding box 2 and is driven by a first motor 7.

One end of the second rotating shaft 9 is rotatably connected to the feed box 2, and the other end is connected to a feed pipe 12, and the feed pipe 12 is arranged obliquely downward, and a cross bar 13 is provided between the second rotating shaft 9 and the feed pipe 12, and a connecting rod 14 is hinged in the middle of the cross bar 13, and a driving rod 15 is hinged on the connecting rod 14, and the driving rod 15 is driven by a second motor 16, and the second motor 16 is arranged on the top of the feed box 2, and a heating box 18 is provided on the side of the feed box 2, and the heating box 18 is connected to the feed box 2 through a first channel 27, and the heating box 18 is connected to a blower 17 on the side away from the feed box 2, and a discharge port 34 is provided at the bottom of the discharge box 3.

[0022] When the feed drying device dries the feed, the first motor 7 is first started, and the first motor 7 rotates to drive the conveyor belt 4 to move. The top movement direction of the conveyor belt 4 is from the feed box 2 to the drying box 1. Then the second motor 16 is started, and the output shaft of the second motor 16 rotates to drive the driving rod 15 to rotate. The driving rod 15 rotates to drive the connecting rod 14 to move. The connecting rod 14 and the cross bar 13 are hinged, and the connecting rod 14 drives the cross bar 13 to move, thereby driving the feed pipe 12 to swing back and forth around the second rotating shaft 9. The feed pipe 12 reciprocates back and forth in the width direction of the conveyor belt 4. At the same time, the feed passes through the feed pipe 12 and falls on the top of the conveyor belt 4 in the feed box 2, so that the feed falls evenly on the conveyor belt 4 The feed is transported into the drying box 1 as the conveyor belt 4 moves. At this time, the blower 17 is started, and the blower 17 draws the outside air into the heating box 18. The heating box 18 is provided with a heating wire, and the heating wire is energized to heat the air. The hot air enters the feed box 2 through the first channel 27, and then enters the drying box 1 through the second channel 28. The feed on the conveyor belt 4 contacts with the hot air, the temperature rises, and the moisture contained in it evaporates into water vapor and flows upward out of the drying box 1 with the hot air. The dried feed continues to move with the conveyor belt 4, and enters the discharge box 3 from the third channel 35, and is discharged from the discharge port 34 at the bottom of the discharge box 3, thus completing the feed drying operation.
