Abstract:

During cleaning process of rice combine, the rice threshed mixtures could adhere to or block the sieve surface. In order to study the interface adhesion law of rice threshed mixtures under different vibration modes, three modes of vibration test bench were designed, including linear vibration, circular arc vibration and jitter. The adhesive mass on working face under three vibration modes kept stable when the vibration time exceeded 15 s. When the vibration amplitude was increased from 10 mm to 30 mm, the adhesive mass on the working face under three vibration modes was effectively reduced. As the vibration frequency was increased from 2 Hz to 3.5 Hz, the adhesive mass on the working face under three vibration modes was quickly reduced. The acceleration peak value of linear vibration working face was obviously higher than that of circular arc vibration and jitter. The linear vibration working face has the best anti-adhesion effect. The influences of test factors on the anti-adhesion capabilities of linear vibration working face in descending order are amplitude, frequency and vibration time. The influence of test factors on the anti-adhesion capabilities of circular arc vibration and jitter working face in descending order are frequency, amplitude and vibration time.
