Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and embodiments, it being understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
Referring to fig. 1 to 3, the present invention provides a rice classifying screen, which comprises a supporting frame 9 and a screen mesh 3 positioned on the supporting frame 9; the side surface of the screen 3 is connected with a support frame 9 through a plurality of press plates 10; the lower end of the screen 3 is provided with an oscillating motor 15, and the side surface of the screen 3 is connected with a supporting frame 9 through a sieve pore adjusting plate; the material of screen cloth 3 is stainless steel generally, utilizes screen cloth 3 regulating plate to install on support frame 9 to there is certain slope contained angle with the horizontal plane. When the oscillating motor 15 is operated, the material on the screen mesh 3 is wholly oscillated and moved to one end of the screen mesh 3. The uppermost screen 3 has the largest diameter and the lowermost screen 3 has the smallest diameter. There is the slope contained angle screen cloth 3 and horizontal plane, and is equipped with on the screen cloth 3 and scrapes flitch 16, scrapes flitch 16 and passes through sliding tray 4 and connect screen cloth 3, and the side of screen cloth 3 is equipped with the silo 2 of connecting the case 14 that gathers materials, is equipped with feed inlet 5 on the silo 2, and 2 side seals of silo, and 2 in-connection of silo have the air-blower. The number of the screen meshes 3 can be 2-4 layers, and the diameter of the filtering holes on each layer of the screen meshes 3 decreases from top to bottom. When the material slides downwards, if the thickness of the material is too large, the sliding speed of the material is too high during vibration, and the situation that the material moves to the tail end of the screen mesh 3 before being sieved easily occurs. In order to further improve the filtering effect, the materials which are not fully screened can be directly returned to the material collecting box 14 through the material groove 2 and the air blower, and secondary screening of the materials is realized. The diameters of the sieve holes on the sieve mesh 3 are generally fixed, the materials are very easy to clamp in the oscillation process, and the materials can be cleaned by the scraper plate 16.
Preferably, the feeding port of the screen 3 of the present invention is provided with a material collecting box 14, a weighing assembly 1 is arranged in the material collecting box 14, and the weighing assembly 1 is connected with the material collecting box 14 through a turnover mechanism.
