[0031] In this embodiment of the invention, when the grain is being transported, it is first transported by the running transfer belt 3, and then by the running conveyor belt 4. When the grain is being transported by the conveyor belt 4, it is transported by the drying tray 10, which can blow hot air from bottom to top to dry the grain.
[0032] In this embodiment of the invention, the drying tray 10 is an existing hot air blower device used for drying grains, which will not be described in detail here;
[0033] In this embodiment of the invention, a conical frame 6 is fixedly installed on the top of the machine body 1. The installation position of the conical frame 6 is directly above the drying tray frame 10, and it is used to collect the blown hot air and impurities contained in the grain.

[0034] In this embodiment of the invention, when hot air blows and dries the grain from bottom to top, the hot air passing through the conveyor belt 4 can enter the conical frame 6 and then be transported to the blower plate 8 through the arc-shaped air supply pipe 7, so that the hot air can be blown onto the transfer belt 3 through the blower plate 8 to complete the preheating treatment of the conveyed grain, thereby improving the drying efficiency of the grain and the energy-saving effect of the equipment.
[0035] In this embodiment of the invention, when hot air dries the grain conveyed above the conveyor belt 4 from bottom to top, it can blow impurities contained in the grain into the conical frame 6, such as chopped straw and grain husks, thereby improving the performance of the equipment.
