Two air hoses and third air hose are entered from the first air hose under pneumatic jig 2 respectively to 2 lower section of pneumatic jig, proportion sieve 5 and 6 air feed of vibrating screen
Side wind from 2 lower to upper part of pneumatic jig flow, by whereabouts it is light it is miscellaneous blow back top, repeat wind-force removal of impurities, enter in this way
Contained light miscellaneous amount greatly reduces in material in follow-up proportion sieve 5, and the second air hose is utilized to sieve 5 lower section air feeds and the to proportion at this time
Three air hoses are aided with wind-force impurity elimination, further go removing light impurities to 6 air feed of vibrating screen while progress proportion winnows, shakes removal of impurities
And dust.
5, vibrating screen 6 is sieved since wind, the second air hose and the third air hose of the first air hose feeding pneumatic jig 2 are respectively fed to proportion
The purpose of wind is different, and institute's required airflow would also vary from, and the feed product weight of feed hopper is entered in the unit interval
Amount can also influence institute's required airflow, therefore the utility model is equal in 7 discharge pipe of main air blower, the first air hose and the second air hose
Equipped with volume damper, the volume damper includes air-flow plate, and the air-flow plate is mounted on each wind by shaft
In pipe, one end of the shaft is stretched out outside air hose, and rotates by 8 drive shaft of motor
When each air hose institute required airflow is adjusted, the utility model is adjusted using automatic control system, such as Fig. 6
It is shown the automatic control system connection relationship diagram, the automatic control system includes controller 16, and and controller
16 connections, and it is separately positioned on the biography of the wind-force at 7 discharge pipe of main air blower, the first air hose, the second air hose and third air hose air outlet
Sensor 21, the motor 8 to control each shaft rotation is also connected to controller 16, since each air hose institute required airflow is mainly by unit
Time enters the decision of the inventory in pneumatic jig, therefore pneumatic gate valve 14 is arranged, as shown in Fig. 2, the pneumatic gate valve 14 includes

It is slidably connected, fixed door-plate 17 is installed with cylinder 19 towards 2 side of pneumatic jig, and push rod and the slide door plate 18 of the cylinder 19 connect
It connects, cylinder 19 controls the flexible of its push rod by solenoid valve 20, and then controls movable doorboard 18, i.e., is pushed away by the control of solenoid valve 20
The degree that bar is released i.e. 2 upper end opening degree of controllable pneumatic jig, to the inlet of control material, the solenoid valve 20 is connected to
Controller 16.Here controller 16 can be the computer for being pre-loaded with control program, wind sensor 21, solenoid valve 20 and motor
8 by cable network or wireless network connection to the controller 16, and unit interval inlet amount has been previously set in controller 16
The relationship of air quantity in push rod released amount and each air hose is pushed with solenoid valve 20.
In addition, main air blower 7, dedusting fan 4, proportion sieve 5 and vibrating screen 6 can be controlled by controller 16 and be opened and closed, also may be used
To manually control, it is introduced by taking the control of controller 16 as an example in the present embodiment.
Material sieves 5 rear ends after pneumatic jig 2, proportion sieve 5 screening, from proportion and enters vibrating screen 6, refering to Fig. 3, vibrating screen
6 include shell 9 and vibration screen, and the vibration screen includes level-one sieve 10 and two level sieve 11, the level-one sieve 10
Sieve pore is more than the sieve pore of two level sieve 11, and the dust entered in the material of vibrating screen 6 is blown away by the wind that third air hose is sent into,
The grain impurity bigger than cereal stays on level-one sieve 10, and the particle impurity smaller than cereal is then fallen in shell, and cereal stays in two level
On sieve 11, level-one sieve 10, two level sieve 11 are removably installed in shell 9, for different material, it is convenient to more
Change the sieve with different size perforations.
Between 9 lower end of shell of vibrating screen 6 and rack 1 be equipped with loss of weight spring, as shown in Figures 4 and 5, the loss of weight spring by
The interior spring 12 and outer spring 13 of coaxial arrangement are constituted, and the interior spring 12 is connect with rack 1 with the lower end of outer spring 13,12 upper end of interior spring
It being connect higher than outer spring 13, and with shell 9, the interior spring 12 being coaxially arranged and outer spring 13 collectively form loss of weight spring, intensity higher,
Buffering effect is more preferable, and the service life is longer.
Multistage pneumatic separation grains separating machine operation principle and process provided by the utility model is as follows：Pneumatic gate valve 14 controls wind
Sieve 2 upper end opening sizes, determine that the unit interval enters the amount of the raw grain material in pneumatic jig 2, thus can determine the first air hose,
Respectively institute's required airflow is set in controller 16 first when carrying out grain selecting using the machine for second air hose and third air hose
The inlet amount of unit interval, required airflow value determines in the release length of 19 push rod of cylinder, each air hose at this time, and controller 16 is sent
The push rod that signal controls cylinder 19 to solenoid valve 20 pushes slide door plate 18 to arrive set value, and main air blower 7 starts air feed, and each wind-force passes
Sensor 21 detects wind-force at each air hose air outlet, and measured value is returned to controller 16, and compared with setting value, is tied according to comparing
Fruit, 16 feedback signal of controller adjusts the opening degree of air-flow plate to each motor 8, until 21 measured value of each wind sensor
It is consistent with setting value.
After the completion of adjustment, you can screened into raw grain material, controller 16 controls dedusting fan 4, proportion sieve 5 and vibration
Sieve 6 is opened, and material enters pneumatic jig 2 by feed hopper 3, and part is gently miscellaneous to be inhaled into dedusting fan 4, contains not yet in the material of whereabouts
The light miscellaneous wind sent by the first air hose being removed, which rises, to be risen, and selection by winnowing removal of impurities is repeated, and material enters proportion sieve 5 and carries out
Proportion screens, and the wind that the second air hose is sent out carries out selection by winnowing removal of impurities to the material in proportion sieve 5, and material enters vibrating screen 6 later, together
When third air duct blow carry out selection by winnowing removal of impurities again, by pneumatic jig 2 repeat selection by winnowing removal of impurities, proportion screening, vibration screening mistake
It is aided with wind-force removal of impurities in journey, effectively improves the dust removal rate of refiner, improve the cleanliness factor of finished product of grain, while avoiding blocking
Screen mesh.
It should be noted that the structure not specifically described in the present invention, such as proportion sieve 5 and each screen fraction
Impurities outlet etc., is the same as those in the prior art, without detailed description.
Technical solutions of the utility model are exemplarily described utility model above in conjunction with attached drawing, it is clear that this practicality
Novel specific implementation is not subject to the restrictions described above, as long as using the methodology and technical solution progress of the utility model
Various unsubstantialities improve, or it is not improved the design of utility model and technical solution are directly applied into other occasions,
It both is within the protection scope of the present invention.
