Detailed Description

The utility model is further described below with reference to the drawings and examples.

As shown in the figure, the grain dryer of the embodiment comprises a frame 1, a plurality of bin units are arranged on the frame along a vertical array, each bin unit comprises a funnel-shaped bin body 2, a bin cover 3 arranged on the bin body, an upper pore plate 4 fixedly arranged in the bin body, a lower pore plate 5 parallelly attached to the lower part of the upper pore plate, a transverse column 6 arranged on the bin body and supporting the lower pore plate, a plurality of comb plates 7 parallelly arranged on the upper pore plate and a material turning push rod 8 connected with each comb plate.

The feed pipe 9 is arranged in the middle of the bottom of the bin body, the feed pipe 10 is arranged in the middle of the bin cover, the feed pipe is connected with the feed pipe at the bottom of the bin body above the feed pipe, and the feed pipe on the bin cover at the uppermost part is connected with the hopper 11.

The front end and the rear end of the lower orifice plate penetrate through the bin body, a front limiting plate 12 is arranged on the front end of the lower orifice plate, and a rear limiting plate 13 is arranged on the rear end of the lower orifice plate; when the front limiting plate is attached to the outer side surface of the bin body, blanking holes on the upper orifice plate and the lower orifice plate are staggered to form a ventilation seam through which grains cannot pass; when the rear limiting plate is attached to the outer side surface of the bin body, blanking holes on the upper pore plate and the lower pore plate are opposite to form through holes for grains to fall; the frame is provided with electric cylinders 14 which are connected with the lower pore plates in a one-to-one correspondence manner and used for pushing the lower pore plates to translate.
