所述的风机11由风机电机19带动,风机11与阶梯型主风道12通过风道变径18螺栓连接,分风道15与梯型主风道12通过连接风道变径14螺栓连接,分风道15与风干段Ⅱ各层风干段侧板17通过法兰螺栓连接,并与对应的圆筒形排风网管道20相通。The fan 11 is driven by a fan motor 19, the fan 11 is connected to the ladder-type main air duct 12 by 18 bolts with variable diameters in the air duct, and the sub-air duct 15 is connected with the ladder-shaped main air duct 12 through 14 bolts connecting the air duct with a reduced diameter. The sub-air duct 15 is connected to the side panels 17 of the air-drying section of each layer of the air-drying section II through flange bolts, and communicates with the corresponding cylindrical exhaust network pipe 20 .

参照图4、图5,所述第一梯形导向板3的下出口宽度和第一梯形导向板3的高度是根据粮食自然流动的休止角设定的,既能让粮食自然流动又能防止粮食外溢。即粮食从储粮段向下流动,经过风干段Ⅱ,最后到达排粮机构Ⅲ。Referring to Fig. 4 and Fig. 5, the width of the lower outlet of the first trapezoidal guide plate 3 and the height of the first trapezoidal guide plate 3 are set according to the angle of repose of the natural flow of the grain, which can not only allow the grain to flow naturally but also prevent the grain from Spill. That is, the grain flows downward from the grain storage section, passes through the air-drying section II, and finally reaches the grain discharge mechanism III.

如图6、7:所述圆筒形排风网管道20正好安装到储粮段Ⅰ内部第一梯形导向板3下出口的中间位置,或安装到风干段Ⅱ每层正对第二梯形导向板16的下出口的中间位置,直径和第一梯形导向板3或第二梯形导向板16的下出口宽度相同,这样既保证第一梯形导向板3或第二梯形导向板16与圆筒形排风网管道20之间的距离能够被自然风吹透,又能保证里面的粮食不发霉。As shown in Figures 6 and 7: the cylindrical exhaust network pipe 20 is just installed in the middle of the outlet of the first trapezoidal guide plate 3 inside the grain storage section I, or installed in the second trapezoidal guide on each floor of the air-drying section II The middle position of the lower outlet of plate 16, diameter and the first trapezoidal guide plate 3 or the lower outlet width of the second trapezoidal guide plate 16 are identical, both ensured like this the first trapezoidal guide plate 3 or the second trapezoidal guide plate 16 and cylindrical shape The distance between the air exhaust network pipes 20 can be blown through by the natural wind, and can ensure that the grain inside is not moldy.

如图11、12所示,下搅龙8壳设计成槽型,方便储存粮食,前后法兰与底座支架7通过螺栓连接,在槽型壳体下面是活动插板,方便清理堵塞的粮食。As shown in Figures 11 and 12, the lower auger 8 shell is designed as a groove, which is convenient for grain storage. The front and rear flanges are connected to the base support 7 by bolts, and there is a movable plate under the groove shell, which is convenient for cleaning the blocked grain.

如图13所示:阶梯型主风道12上窄下宽,可以避免风量分配的不均匀。As shown in Figure 13: the stepped main air duct 12 is narrow at the top and wide at the bottom, which can avoid uneven distribution of air volume.

实施例2:Example 2:

如图14所示,此种风干机结构为自然通风型,与机械通风不同的地方在于不使用风机,而是改由烟囱式风道22,在烟囱式风道顶部安装一无动力风机21,靠自然风风干。As shown in Figure 14, the structure of this kind of air dryer is a natural ventilation type, and the place different from mechanical ventilation is that no blower fan is used, but a chimney-type air duct 22 is changed, and an unpowered fan 21 is installed on the top of the chimney-type air duct. Air dry by natural wind.
