Abstract
The utility model discloses an air-volume-adjustable exhaust fan used for a cereal drying machine. The air-volume-adjustable exhaust fan comprises an air drum, in which multiple blades arranged in an annular array are installed. The blades are rotatably supported between the inner wall of the air drum and the axle center of the air drum. A rotary disc, having the same center with the air drum, is arranged at the outer wall of the air drum at an interval. One side, close to the blades, of the inner wall of the air drum is fixedly provided with rotary shafts used for controlling rotation of the blades at the middle portions. The other end of each rotary shaft penetrates through the air drum and is fixedly connected with the rotary disc. A carrying handle is additionally arranged at the outer wall of the rotary disc. The air-volume-adjustable exhaust fan used for the cereal drying machine has following beneficial effects: the air-volume-adjustable exhaust fan is simple in structure, convenient in production, quick in disassembly and high in applicability; according to needs, air exhaust volume and total pressure of the cereal drying machine can be adjusted; and cereals are stably ensured during a drying process.
Description
Technical field
The utility model relates to grain machinery technical field, is specifically related to a kind of air volume adjustable air bells exhauster for grain drier.
Background technique
Grain drier is the one of dryer, is the general designation of various grain drying equipments.Be provided with air bells exhauster at grain drier outlet housing, for drying layer hot blast is extracted out, flowed cereal is dried by hot blast, the exhaust air rate size of air bells exhauster and total head can directly affect the drying effect of grain drier drying layer.Existing market is mainly the oven dry degree that directly determines of the air bells exhauster by buying different capacity, and so not only controllability is poor, but also can directly affect the drying effect of dryer.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of simple in structure, easy to use, can be according to using the air volume adjustable air bells exhauster for grain drier that need to adjust exhaust air rate size.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
For an air volume adjustable air bells exhauster for grain drier, comprise air duct, the blade that several circular array shapes are arranged is installed in described air duct; Described blade rotary is supported between air duct inwall and air duct axle center, on described air duct outer wall, the rotating disk of concentric setting is installed in gap, blade can be controlled the rotatingshaft of described blade rotary near a middle side part fixed installation of air duct inwall, the other end of described rotatingshaft, through air duct, is fixedly connected on described rotating disk.
Further improvement as technique scheme:
On the outer wall of described rotating disk, add and move handle.
Further improvement as technique scheme:
Between described air duct inwall and air duct axle center, add pull bar.
The utlity model has following advantage: the utility model is simple in structure, easy to make, dismounting is convenient, can, according to using needs, regulate big or small exhaust air rate and the total head of grain drier, and applicability is strong, for cereal provides stable guarantee in Dry run.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
As shown in Figure 1, a kind of air volume adjustable air bells exhauster for grain drier of the present embodiment, comprises air duct 1, and the blade 2 that several circular array shapes are arranged is installed in described air duct 1.
In order to solve the technical problem described in background technique, the technical solution of the utility model is, described blade 2 rotary supports are between air duct inwall 3 and air duct axle center 4, on described air duct 1 outer wall, the rotating disk 5 of concentric setting is installed in gap, blade 2 can control near a middle side part fixed installation of air duct inwall 3 rotatingshaft 6 that described blade 2 rotates, the other end of described rotatingshaft 6, through air duct 1, is fixedly connected on described rotating disk 5 by fork 7.
When use, by rotary turnplate 5, just can utilize rotatingshaft 6 to be with moving vane 2 axial-rotations, adjust blade angle, can change air output and pressure.
Embodiment 1
In the present embodiment, for the convenient rotating disk 5 that rotates, can on the outer wall of rotating disk 5, install additional and move handle 8.
Embodiment 2
In the present embodiment, in order to improve the bulk strength of air duct, can between air duct inwall 3 and air duct axle center 4, install pull bar 9 additional.
The foregoing is only preferred implementation of the present utility model, protection domain of the present utility model is not limited in above-mentioned mode of execution, and every technological scheme that belongs to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, some improvements and modifications of carrying out under the prerequisite that does not depart from principle of the present utility model, these improvements and modifications also should be considered as protection domain of the present utility model.
