Abstract
The utility model relates to a grain cleaning centrifugal fan device, and relates to the field of manufacture of wind turbines. A motor and a centrifugal fan are fixed on a main framework to form the grain cleaning centrifugal fan device, a fan rack is seated on the main framework, an axial fulcrum of a shell of the centrifugal fan is seated on a crossbeam of the fan rack in a movable fit manner, and a driving wheel of the motor seated on the main framework is in transmission connection with a driven wheel of the centrifugal fan; and an arc-shaped adjusting slide groove is arranged on the back of the shell of the centrifugal fan, and the centrifugal fan is fixed with the fan rack via fastening bolts. The grain cleaning centrifugal fan device is reasonable in structural design, realizes adjustment of the rotation speed of the fan and accordingly realizes change of wind speed. The fan is further provided with the adjustable fan rack which has a supporting function, more importantly, adjustment of all sides of the fan can be realized, and the angle of the fan can be changed. The fan rack is separated from the main framework, and ground wheels are mounted on the framework, so that the distance between the fan and a screen is adjusted quite conveniently; and the framework is further provided with a simple hydraulic adjusting device, the height and the angle of the fan are adjusted in a general direction, and furthermore, the angle of the fan can be adjusted via the adjusting slide groove of the fan.
Description
Technical field
The utility model relates to a kind of manufacturing field of wind motor, relates to a kind of grain cleaning centrifugal blower device specifically.
Background technology
Centrifugal blower is traditional two-sided supply fan of agricultural type.In the compass screen surface width range, blower fan is arranged to two sections.Blade adopts the forward direction prismatic blade, and the main effect of centrifugal blower is that the seed under the sieve, clever chaff and short stem are separated.Fan airflow can easily blow away clever chaff, but is difficult to the short stem under the sieve is separated with seed.Increase wind speed, help the foreign material under the sieve are blown away, grain cleaning rate is improved, but air velocity is too high, be prone to the seed that the back sieve falls is blown out outside the machine, increase the seed loss late.
Summary of the invention
The utility model is intended to overcome the deficiency of prior art, and a kind of grain cleaning centrifugal blower device is provided.
The grain cleaning centrifugal blower device of the utility model; Be on mainframe, to have fixed motor and centrifugal blower formation; At the mainframe seat of honour blower fan frame is arranged; Seat is on the crossbeam of blower fan frame movingly for the axial fulcrum of the casing of centrifugal blower, and the follower of driving wheel and the centrifugal blower of the motor of seat on mainframe is driving coupling mutually.
As the further improvement of the utility model, described motor is a buncher.
As the further improvement of the utility model, there is arc to regulate chute and fix at the back of the casing of centrifugal blower through fastening bolt and blower fan frame.
As the further improvement of the utility model, follower is to be connected with the armature spindle of centrifugal blower by bearing block, torquemeter and shaft coupling.
As the further improvement of the utility model, a side leg of described mainframe is to be replaced by hydraulic cylinder.
The grain cleaning centrifugal blower device of the utility model, has been realized the adjustment of rotation speed of fan at reasonable in design, thereby realizes the change of wind speed.Blower fan has also adopted the adjustable fan frame, except that the effect of playing support, the more important thing is the adjustment of the upper and lower and forward and backward position that can realize blower fan and changes the blower fan angle.The blower fan frame is separated with mainframe, and frame is equipped with land wheel, and the distance of adjusting blower fan and sieve like this is very convenient; Frame also is furnished with easy hydraulic regulating device, realizes raising from general orientation the height and the angle of rectification campaign machine, and in addition, the angle of blower fan can also be regulated through the adjusting chute of blower fan.
Description of drawings
Fig. 1 is the grain cleaning centrifugal blower apparatus structure sketch map of the utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
The grain cleaning centrifugal blower device of the utility model; Be on mainframe 1, to have fixed motor 2 to constitute with centrifugal blower 3; At mainframe 1 seat of honour blower fan frame 4 is arranged; Seat is on the crossbeam 6 of blower fan frame 4 movingly for the axial fulcrum of the casing 5 of centrifugal blower 3, and there is arc adjusting chute 10 at the back of the casing 5 of centrifugal blower 3 and fixes through fastening bolt and blower fan frame 4.The follower 9 of driving wheel 8 and the centrifugal blower 3 of the motor 2 of seat on mainframe 1 is driving coupling mutually.Follower 9 is to be connected with the armature spindle of centrifugal blower 3 by bearing block 11, torquemeter 12 and shaft coupling 13.Described motor 2 is a buncher.
And a side leg of mainframe 1 can be replaced by hydraulic cylinder 14.
