The invention discloses a
laser opposite shooting grain flow monitor experimental platform device and a control method. The
laser opposite shooting grain flow monitor experimental platform device comprises a rack, a grain box, an adjustable grain
discharge box, a grain
discharge slide way, a feeding
auger mechanism, a lifting device, a lifting device angle regulating mechanism, and a power mechanism, wherein the adjustable grain
discharge box is arranged at the uppermost position of the rack, the grain box is above the
auger, grain falls under gravity from the grain discharge box, enters the grain box through the grain discharge slide way, and then falls into the
auger through the grain box, the grain enters the lifting device under push of the auger, then is lifted through a scraper in the lifting device, in lifting, the grain passes a
laser opposite shooting flow sensor and is thrown out from a grain discharge port of the lifting device finally, and a weighing sensor at the bottom ofthe grain box weighs reduced grain so as to calibrate the flow sensor. Through adoption of the device, grain is reused in the
test platform, when the grain needs to replace, the direction of the grain discharge slide way is regulated, the grain is released and stops being reused. The angle of the lifting device can be regulated, and
technical support is provided for determination of an optimal inclination angle of the lifting device.
