Preferably, described bearing is taper roll bearing.
Preferably, the upper surface of described supporting plate is downward-sloping in discharge outlet.
Preferably, the diameter of described first air-vent and the second air-vent increases from top to bottom gradually, and the maximum gauge of the first air-vent and the second air-vent is all no more than soybean diameter.
Preferably, the upper surface of described cover is circular arc.
Compared with prior art, the invention has the beneficial effects as follows: this spiral soybean drying unit, soybean can be flow down slowly by spiral-tube, the rotation of spiral-tube soybean can be made to mix evenly, be heated evenly, and the direction of the rotating speed of motor and electric machine rotation can change the time of speed that soybean stays and oven dry.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1-2, the invention provides a kind of technical scheme: a kind of spiral soybean drying unit, comprise bracing frame 1 and feeding cylinder 3, supporting plate 2 is provided with in support frame as described above 1, described feeding cylinder 3 is positioned at directly over supporting plate 2, described feeding cylinder 3 is fixedly connected with supporting plate 2 by supporting leg 4, the upper end of described feeding cylinder 3 is provided with charging aperture 5, spiral-tube 6 is provided with in the middle part of the inner chamber of described feeding cylinder 3, the lower end of described spiral-tube 6 is connected with the external diameter cylindrical bump 61 less than the external diameter of spiral-tube 6, the middle part of described supporting plate 2 is provided with jack 7, described jack 7 internal fixtion is provided with bearing 8, described projection 61 is plugged in bearing 8, and projection 61 is fixedly connected with the inner ring of bearing 8, such spiral-tube 6 just can block bearing 8 completely, soybean is unlikely to fall into in bearing 8, described bearing 8 is taper roll bearing, such power bearing axial direction, the lower surface of described projection 61 is connected with motor 9, described motor 9 is fixed on bracing frame 1, the upper surface circumference of described supporting plate 2 is provided with baffle plate 10, the side of described baffle plate 10 is provided with discharging opening 11, the upper surface of described supporting plate 2 is downward-sloping at discharging opening 11 place, be convenient to the outflow of soybean, the upper end of described spiral-tube 6 is provided with cover 12, the upper surface of described cover 12 is circular arc, the middle part of described cover 12 is provided with hole 121, air inlet pipe 13 is plugged with in described hole 121, described air inlet pipe 13 is fixed on bracing frame 1, described air inlet pipe 13 is connected with air-heater 14, and air-heater 14 is positioned at the side, bottom of bracing frame 1, the circumference of described spiral-tube 6 is provided with helical-blade 15, the circumference of described spiral-tube 6 is evenly provided with the first air-vent 16, the circumference of described feeding cylinder 3 is evenly provided with the second air-vent 17, the diameter of described first air-vent 16 and the second air-vent 17 increases from top to bottom gradually, and the maximum gauge of the first air-vent 16 and the second air-vent 17 is all no more than soybean diameter.
Operation principle: after motor 9 starts, spiral-tube 6 starts to rotate, soybean flows to from charging aperture 5, under the effect of helical-blade 15, flow to bottom slowly, at this moment air-heater 14 is started working, top blast hot-air inwards, the diameter of the first air-vent 16 and the second air-vent 17 increases from top to bottom gradually, blow out the gas that goes like this evenly, soybean is dropped on supporting plate 2 after flowing to bottom, baffle plate 10 stops outside soybean and spatters, then soybean is flowed out through discharging opening 11, and discharging opening 11 place is provided with certain gradient, is conducive to the outflow of soybean.
Although illustrate and describe embodiments of the invention, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments without departing from the principles and spirit of the present invention, scope of the present invention is by claims and equivalents thereof.
