The purpose of this utility model is realized by following technical scheme:

A kind of dryer, its formation is that it comprises cylindrical shell and power transmission shaft, the midfeather of having set up defences in the said cylindrical shell is drying chamber above the midfeather, is the hot blast chamber below, midfeather is provided with passage, the hot blast chamber is provided with air inlet, and drying chamber one end is provided with charging aperture, and the other end is provided with discharge gate and exhaust outlet, being fixed with the stirring material pushing tooth on the vertical power transmission shaft that places in the drying chamber, stirring material pushing tooth and show in the shape of a spiral shape along axle and arrange at interval.

According to the different cultivars of oven dry material, the gear tip clearance that stirs material pushing tooth is apart from also different, and general gear tip clearance stirs material pushing tooth and is distributed on the power transmission shaft apart from selecting between 30mm-150mm.

According to the different cultivars of oven dry material, the aperture of the passage on the midfeather is also different with pitch of holes, and general passage is directly selected φ 2mm-φ 10mm for use, and pitch of holes is selected 50mm-100mm for use.The dryer of different structure size, the quantity of its dividing plate passage are also different, as the dryer that is used to dry straw of long 6m, wide 1.3m, high 2m; The passage quantity of dividing plate is that the aperture is Φ 4-Φ 8mm between 2000-3000, and pitch of holes is between 60mm-80mm.

For operating efficiency and the product dries quantity that improves dryer, be provided with air-introduced machine in the air inlet of said hot blast chamber and the pipeline between hot air source, the exhaust outlet of drying chamber and an air exhauster join, perhaps the air inlet of hot blast chamber directly joins with the pipeline of hot air source, and the direct and blast pipe of the exhaust outlet of drying chamber joins.

For the charging aperture of drying chamber can close wind and be convenient to charging simultaneously, the charging aperture place of drying chamber is provided with the feed impeller that power drives, and for the drying chamber discharge gate can close wind and be convenient to discharge simultaneously, the discharge gate place is provided with the marker impeller that power drives.

Drying machine structure provided by the utility model is simple, adopts profile of tooth screw feeder structure, and material is fully contacted with hot blast, and can promote material continuously and discharge from discharge gate, can realize working continuously.This speculative investment is little, take up an area of less, easy to operate, dries quantity is good.This dryer particularly suitable oven dry straw and piece, sheet, section shape material.
