For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of roller drier, comprise base and be located at the drying machine body on base, the import department of drying machine body is provided with material intake mechanism, described material intake mechanism comprises the support being located on base, support is provided with Power Drive Unit and carrier pipe, the interior coaxial rotating shaft being rotatably connected on support that is provided with of carrier pipe, rotating shaft is stretched out carrier pipe one end and is connected with Power Drive Unit by actuating unit, carrier pipe is horizontally disposed with, discharging opening one end of carrier pipe extend in drying machine body by the charging aperture of drying machine body, carrier pipe is provided with feed hopper on this external top, one end of drying machine, in rotating shaft, be provided with vertically packing auger blade, the pitch of packing auger blade first reduces rear increase by feed hopper to discharging opening.
Described carrier pipe is provided with at least one row's stirring screw vertically, and every is stirred screw and is all threaded with carrier pipe and radially extend in carrier pipe.
The discharging opening place of described carrier pipe is provided with the broken net of material by set bolt.
Described support is provided with two fixed heads, the top of fixed head is provided with the installation hole slot of circular arc, the radius of hole slot and the exradius of carrier pipe are installed to be equated, on carrier pipe, be arranged with the installing plate of annular, carrier pipe is placed in the installation hole slot of two fixed heads, and the fastening bolt by axial setting between installing plate bottom and fixed head removably connects.
Adopt technique scheme, Power Drive Unit is reducing motor, actuating unit is tape handler, reducing motor drives rotating shaft to rotate by tape handler, material enters in carrier pipe by feed hopper, packing auger blade in rotating shaft rotarily drives material and moves to discharging opening, because the pitch of packing auger blade first reduces rear increase by feed hopper to discharging opening, be that packing auger blade is variable-pitch blade, material is first extruded then loose in carrier pipe, stirring under the stopping of screw, material is fractured into discrete shape simultaneously.The pitch of packing auger blade first reduces rear increase, and corresponding compression ratio first reduces rear increase.Packing auger blade is snapped together by the not equidistant blade of multistage, stirs screw and is located at the junction that packing auger blade is fastening.The broken net of material is installed at the discharging opening place of carrier pipe, can when discharging, to material, further cuts apart and fragmentation.The broken Netcom of material crosses bolt and is arranged on auger discharging mouth place, can select the fragmentation net of different pore size to realize flexibly according to different materials and control.
Carrier pipe is placed in the installation hole slot of two fixed heads, and the fastening bolt by axial setting between installing plate bottom and fixed head removably connects, and this structure is fixed, is convenient to dismounting.Prop up and be erected on base, be convenient to so whole carrying.
The utility model has been used for reference the operation principle of bulking equipment in grain machine equipment, realized the object of while bulk material when charging, improved the contact area of heat exchanger tube in material and roller drier, thereby improved heat exchange efficiency, saved energy consumption, reduced production cost, practical, be easy to apply.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of material intake mechanism in Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, a kind of roller drier of the present utility model, comprise base 13 and be located at the drying machine body 1 on base 13, the import department of drying machine body 1 is provided with material intake mechanism, material intake mechanism comprises the support 2 being located on base 13, support 2 is provided with Power Drive Unit 3 and carrier pipe 4, the interior coaxial rotating shaft 5 being rotatably connected on support that is provided with of carrier pipe 4, rotating shaft 5 is stretched out carrier pipe 4 one end and is connected with Power Drive Unit 3 by actuating unit 6, carrier pipe 4 is horizontally disposed with, discharging opening one end of carrier pipe 4 extend in drying machine body 1 by the charging aperture of drying machine body 1, one end top of carrier pipe 4 outside drying machine body 1 is provided with feed hopper 7, in rotating shaft 5, be provided with vertically packing auger blade 8, the pitch of packing auger blade 8 first reduces rear increase by feed hopper 7 to discharging opening.
