[0023] An environmentally friendly grain dryer with dust removal during discharging comprises a drying tank 1, a feeding piece 2 is fixedly mounted at the lower end of the drying tank 1, the lower end of the feeding piece 2 gradually narrows and dust removal holes 5 are symmetrically opened on both sides, a hair dryer 3 is fixedly mounted on one side of the feeding piece 2, a connecting pipe 4 is fixedly mounted on the output end of the hair dryer 3, an end of the connecting pipe 4 away from the hair dryer 3 extends into the feeding piece 2 and a dust removal piece 21 is fixedly mounted, a plurality of groups of air outlet ends 22 are fixedly mounted on both sides of the dust removal hole 5 of the dust removal piece 21, a curved panel 20 is fixedly mounted above the dust removal piece 21 in the feeding piece 2, a feeding assembly is arranged at the bottom of the drying tank 1, and the feeding assembly can ensure that the dried grain falls onto the curved panel 20 in a concentrated manner.

[0024] Among them, the discharging assembly includes a lower fixed plate 18 and a material guide 15. The lower fixed plate 18 is fixedly installed at the lower end of the drying tank 1. The upper movable plate 17 is rotatably installed on the lower fixed plate 18. The lower fixed plate 18 is provided with a lower unloading trough 23. The upper movable plate 17 is provided with an upper unloading trough 19. The upper unloading trough 19 can overlap with the lower unloading trough 23.

[0025] The guide member 15 is fixedly mounted at the lower end of the drying tank 1 and the lower end of the guide member 15 is located on the upper surface of the upper movable plate 17 .
