Separating machine

Abstract

The invention relates to a separating machine. The separating machine comprises a box body, a feeding bin, an air compressor, an upper screen, a lower screen, pin shafts, a rack, a rotating shaft, a tooth-missing gear, a connecting rod, a limiting spring, a motor and a material collecting groove, wherein the feeding bin is arranged at the top end surface of the box body, the material collecting groove is formed in the bottom end surface of the interior of the box body, the air compressor is arranged at the left end surface of the interior of the box body, the upper screen and the lower screenare rotationally connected to the interior of the box body, the rack is connected in the box body in a sliding mode, the connecting rod is fixedly arranged at the right end of the rack, the two ends of the connecting rod are movably connected to the pin shafts, the tooth-missing gear is arranged on the rotating shaft, the rotating shaft is fixedly connected with the output end of the motor, the upper screen is connected to the top end surface of the box body through the limiting spring, and the tooth groove of the tooth-missing gear is meshed with the tooth groove of the rack. By the design, the two screens are driven to rotate in a reciprocating mode through the cooperation of an incomplete gear mechanism and the limiting spring, impurities are enabled to roll on the screens, and the problem that the impurities cannot be screened due to stacking is solved.

Description

technical field [0001] The invention relates to the field of rice processing equipment, in particular to a separator. Background technique [0002] Rice is the finished product of rice after cleaning, husking, rice milling, finishing and other processes. The germ and aleurone layers of rice contain nearly 64% of rice nutrition and more than 90% of the nutrients needed by the human body, and are the main food of the southern people. Rice contains about 75% carbohydrates, 7%-8% protein, 1.3%-1.8% fat, and is rich in B vitamins. The carbohydrates in rice are mainly starch, and the protein contained is mainly rice glutenin, followed by rice gelatin and globulin. High, digestibility 66.8%-83.1%, is also a kind of higher in cereal protein. [0003] When rice is harvested, there are impurities such as stones, skinned rice or rice grains mixed inside, which need to be removed. However, the position and angle of the screen of the traditional separation mechanism are fixed, and the...
