Beschreibung
Zusammenfassung:	The utility model relates to the technical field of grain drying machines, in particular to a grain drying machine air temperature adjusting device which comprises a hot air pipeline, a first sleeve is arranged on the periphery of the hot air pipeline in a sleeved mode, and a plurality of evenly-distributed third air inlet holes are formed in the periphery of the hot air pipeline. First air inlet holes in one-to-one correspondence with the third air inlet holes are formed in the circumferential direction of the first sleeve, the first air inlet holes are located in the upstream of the correspondingly-formed third air inlet holes in the hot air flow flowing direction of the hot air pipeline, and air suction pipes are installed between the first air inlet holes and the correspondingly-formed third air inlet holes in a communicating mode. Due to the fact that the air suction pipes are arranged on the periphery of the hot air pipeline, the entering speed of cold air flow can be increased, compared with a single-s
