Vibrate cleaning plant.
Technical background
It is one of critical process during grain harvest to clean, and cleaning loss is most important loss during grain harvest
Form, the height of cereal clean rate to follow-up grain storage and transportation, be machined with important influence, the particularly wet glutinous paddy such as rice, rape
It is big that thing cleans task difficulty, and loss late is high, and clean rate is low, therefore, optimizes wet glutinous crop vibrative and cleans operation form, further carry
The transaction capabilities of high cleaning plant are to ensure the key that wet glutinous cereal drop damage increases income.
At present, domestic and international grain harvesting machine generally use Type Airflow Rice-Wheat Cleaning Apparatus with Centrifugal Fan-Oscillating Sieve, in operation process, vibrating screen is driving
Reciprocal simple harmonic motion is done under the drive of mechanism, under the cooperation of fan airflow, emersion object is shaken on compass screen surface, in emersion object respectively into
Point it is gradually disengaged, is layered, the glume of lighter weight, debris, short stalk discharges body with air-flow, and the seed of heavier mass can be
Moved on compass screen surface, seed falls into sieve aperture during movement, is finally completed sieve.However, high-moisture percentage cereal passes through threshing
After the rubbing of device, impact, the substantial amounts of bleeding sap of emersion object surface attachment, emplastic promotes in emersion object each component constantly
It is adhered to each other, forms block aggregate, the single reciprocal shake of vibrating screen can not breaks up the material of reunion, and seed is swept along in thing
It can not be separated in time in dough, with the extension of activity duration, material is accumulated on sorting screen surface, causes sieve pore blockade, is cleaned
The operating efficiency of sieve is greatly reduced.Under conditions of cleaning plant structural parameters are constant, by the vibration for greatly improving sorting screen
Frequency, the job parameter such as rotating speed of wind turbine can reduce the appearance of reunion material to a certain extent, but certainly will produce more
Energy consumption, shorten the service life of cleaning plant, and cause sorting purpose insufficient, percentage of impurity is excessive.
Take a broad view of the technology and performance of above-mentioned grain cleaning machine, be badly in need of a kind of being suitable for wet glutinous cereal, turning over that Throwing abilities are strong, subtract
Glutinous desorption, the reciprocal deflecting that operating efficiency is high, reliability is high turn over the wet glutinous high-efficiency grain vibration cleaning plant of Throwing formulas.
