In the preferred embodiment of the present invention, drying cavity one and the bottom end of drying cavity two are equipped with material pneumatic distribution Device.
In the preferred embodiment of the present invention, blower fan one and blower fan two connect drying cavity one and drying cavity two respectively Bottom.
In the preferred embodiment of the present invention, drying cavity one, drying cavity two are by circular cylindrical cavity and cylindrical cavity Hollow drying pipe is provided with funnel cavity composition under body, the cylindrical cavity body, the drying ttom of pipe end is deeply to leakage In the cavity that struggles against.
In the preferred embodiment of the present invention, the bottom of drying pipe also is provided with grain discharging opening, and grain discharging opening Several are radially distributed with along drying pipe.
In the preferred embodiment of the present invention, warm-air pipe and air intake tube outer surface are enclosed with heat-insulation layer.
The beneficial effects of the invention are as follows:It is simple in construction, by drying the cooperation of pipe and feeding packing auger, realize the He of drying cavity one The grain of the inner bottom part of drying cavity two is constantly blown out to drying cavity one and drying cavity two by hot air apparatus and cooling air unit, is realized The circulation drying of grain;Again because hot air apparatus replaces the lasting air intake of air intake and cooling air unit so that drying cavity one and drying Temperature equalization in chamber two, reduces the coking of grain, effectively realizes the uniform drying of grain.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention.
Embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
A kind of grain drier as shown in Figure 1, including frame 1, frame 1 is provided with hot air apparatus, cooling air unit and is used for Hold the drying cavity group of cereal, drying cavity group is symmetrically arranged drying cavity 1 and drying cavity 23, drying cavity 1 and drying cavity Hollow drying pipe 4 is equipped with 23, drying pipe 4 bottom is connected to hot air apparatus, and drying pipe 3 top is less than drying cavity top, The bottom of feeding packing auger 5 in feeding packing auger 5, drying cavity group is equipped with the lower end of drying pipe 4 in drying cavity group to be additionally provided with and hot blast The hot air inlet 6 of device connection and the cold air inlet 7 of cooling air unit connection, hot air apparatus include air pump 8, the drying being sequentially connected Heater 9, warm-air pipe 10, hot-air distributor 11 and blast pipe 12, the blast pipe 12 are two, and drying cavity 1 is connected respectively With drying cavity 23, and drying cavity 1 and drying cavity 23 pass through blast pipe 12 connect hot-air distributor 11, hot-air distributor 11 Controller is connected, cooling air unit includes the blower fan 1 and blower fan 2 14 being connected with drying cavity 1 and drying cavity 23, drying cavity 1 and the top of drying cavity 23 be all connected with the elevator 15 that is fed for cereal, be equipped with grain in drying cavity 1 and drying cavity 23 Full device 16, drying pipe 4 top is additionally provided with grain discharging opening 17, and drying cavity 1 and the peripheral of drying cavity 23 are additionally provided with insulation dress Put.
Drying cavity 1 and the bottom end of drying cavity 23 are equipped with material pneumatic distributor 18, realize discharging and the air-flow of grain Air inlet is controlled, when there is grain discharge, and material pneumatic distributor realizes that grain-export is opened, and simultaneously closes off air inlet, facilitates grain Food discharge.
