3 results about "Winnowing" patented technology

The invention discloses an impurity removing machine. The impurity removing machine is characterized by comprising a base, a shell installed on the base, a feeding mechanism, a winnowing mechanism, a screening mechanism and a power mechanism. The feeding mechanism comprises a feeding hopper, a feeding roller and a feeding gate. The winnowing mechanism comprises a volute arranged on the left side of the feeding mechanism, a motor installed in the volute, and a centrifugal impeller installed on an output shaft of the motor. The screening mechanism comprises a first-layer screen, a second-layer screen, a third-layer screen and a fourth-layer screen which are sequentially located in the shell from top to bottom. The power mechanism comprises a motor, a main shaft and an auxiliary shaft. A gear is installed on an output shaft of the motor, and the motor, the main shaft, the auxiliary shaft and the gear of the feeding roller are in transmission connection through chains. Huge impurities, large impurities, impurities in same size as grains and small impurities, such as rice straw chippings of grains, can be rapidly and accurately screened out, and the impurities are classified and tested. The impurity removing machine is suitable for impurity detection of grains and oil departments such as grain depots and quality supervision departments.

The invention discloses a multiple winnowing device for tobacco shreds, which comprises an equipment main body, and the equipment main body comprises an accommodating mechanism for performing multiple winnowing on the tobacco shreds; the winnowing mechanism is arranged in the containing mechanism and comprises a first winnowing piece, a second winnowing piece and a third winnowing piece, and the wind power and the heights of the first winnowing piece, the second winnowing piece and the third winnowing piece are sequentially decreased; the collecting mechanism is arranged in the containing mechanism, located below the winnowing mechanism and used for collecting different tobacco shreds screened out by the first winnowing piece, the second winnowing piece and the third winnowing piece. By arranging the equipment body, in the winnowing process, wind power blowing is matched with gravity falling to automatically sort tobacco shreds into four groups of different types of tobacco shreds, compared with a traditional winnowing device adopting pure wind power sorting, the energy loss needed by winnowing is smaller, the economic benefit of an enterprise is improved, and the economic benefit of the enterprise is improved. And unified classified recycling is achieved through the collecting mechanism, the using effect of the device is better, treatment by a user is facilitated, and the practicability of the device is effectively improved.
