Grain drying machine

Abstract

The invention relates to a grain drying machine, comprising a frame, on which a hot air device, a cold air device and a drying chamber group for storing grain are arranged, and the drying chamber group is a symmetrically arranged drying chamber one and a drying chamber group. Chamber 2, drying chamber 1 and drying chamber 2 are equipped with hollow drying pipes, the bottom of the drying pipe is connected to the hot air device, the top of the drying pipe is lower than the top of the drying chamber, and the drying chamber in the drying chamber group The lower ends of the dry pipes are provided with feeding augers, and the lower part of the feeding augers in the drying chamber group is also provided with a hot air inlet connected to the hot air device and a cold air inlet connected to the cold air device. Through the cooperation of the drying pipe and the feeding auger, the circular drying of the grain is realized; and because of the alternate air intake of the hot air device and the continuous air intake of the cold air device, the temperature in the first drying chamber and the second drying chamber is equalized, Reduce the coking of grain and effectively realize the uniform drying of grain.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a grain dryer. Background technique [0002] At present, the popularity rate of grain mechanized drying is very low. The boiler is mainly used to heat and dry the grain in the drying tower. The disadvantage is that the heat loss is large during the drying process, which wastes energy and causes environmental pollution; The grain is heated unevenly, and the grain on the periphery may be overheated and cause coking, while the grain in the center is not dehydrated due to less heat, resulting in a decline in grain quality and poor drying effect. Contents of the invention [0003] The present invention aims to solve the above defects, and provides a grain dryer. [0004] In order to overcome the defects in the background technology, the technical solution adopted by the present invention to solve the technical problem is: a grain dryer, including a frame, on which a hot air de...
