Outer transmission；Power is driven by V-shaped band (7b), and in power output to screw conveyor shaft (4b), entire mechanical system is in running order；
Cereal is pre-installed in tanker (2), is then opened first and is adjusted valve plate (2b), and cereal relies on reenters feeding screw feeder mechanism certainly
(4), valve plate (2b) adjusting grain feed quantity size can be adjusted by adjusting first at this time；It feeds screw feeder mechanism (4) and pushes grain
After food enters elevator (5) bottom, drive the scraper plate (5e) on chain (5d) by grain hoisting by the lower sprocket (5c1) of bottom
To elevator grain outlet, then investment may bring up tanker (3)；
By rotating the adjusting handle (6e) of elevator angle adjusting mechanism (6), adjusting screw rod (6c) rotation is driven, makes to adjust and slide
Smooth guide rod of the block (6b) in regulating box (6a) is moved forward and backward, connecting rod (6d) the traction elevator being connected with adjusting slider (6b)
(5) it is rotated around screw conveyor shaft (4b), to change the tilt angle of elevator (5), targetedly carries out experimental study；It is adjustable simultaneously
Tanker (3) can be slid back and forth along slide rail guide (1i) out, so that it is guaranteed that grain, which accurately enters, may bring up tanker
(3)；Weighing sensor (9) can be weighed in real time to tanker (2) is entered；Laser opposite-radiation cereal is housed on elevator channel (5a)
Flow sensor carries out real-time monitoring to by the grain of sensor；To carry out multiplicating experiment, can directly open adjustable
The second of tanker (3) bottom adjusts valve plate (3c) out, and cereal slideway of being put out cereal is made to enter tanker (2)；It, can to terminate to test
First to pull out the connecting pin (8a2) for slideway lower end of putting out cereal, promotion puts out cereal slideway (8) around the rotation axis that may bring up at tanker grain outlet
(8a1) rotates and slides into another direction, and cereal is made to draw off experimental bench, opens simultaneously unloading for the feeding screw feeder casing lower end (4a)
Grain lid (4c) clears up the cereal for remaining in screw feeder bottom.
