Abstract

The utility model relates to a rice processing machine, particularly a high effective separation sieve plate for grains and brown rice. The utility model can separate the vibrating grains and brown rice with slope bosses according to the gravity difference of paddies and brown rice. The bosses are uniformly and staggeringly arranged on the surface of a base body of the sieve plate, and the bottom parts of the bosses form a rectangle or other special shapes, wherein two asymmetric slopes are bulged at the direction of length of the rectangular bosses. Two symmetric inclined end surfaces are bulged at the direction of width of the front slopes of the bosses and the back vertical surfaces of the bosses. The utility model changes an original technology that sieves of different apertures are stamped on a steel plate to separate the grains and the brown rice, and in vibration, the grains and the brown rice are separated through the slope bosses due to the difference of gravity. The sieve plate has the advantages of high separation efficiency of the grains and the brown rice, thorough separation, energy saving and practicality.

Description

Efficient grain rough separating screen plate

Technical field

The utility model relates to the rice processing equipment, and it is different to refer in particular to a kind of gravity according to paddy and brown rice, and the efficient grain rough separating screen plate that utilizes grain that the inclined-plane boss will vibrate and brown rice to separate.

Background technology

Modern large-scale rice processing unit procedure is: earlier with hulling machine with the paddy broken shell after, selection by winnowing is shelled into brown rice, polishing then, classification, look choosing, packing are dispatched from the factory.But the unclean grain that much shells is often arranged in the brown rice, and in order to remove grain in the rice, traditional practice is to adopt with the round-hole mesh in different apertures grain to be separated greater than the principle of the grain of rice according to the grain external diameter, broken shell processing again.Because the grain and the grain of rice all respectively have size, thus often clear through the also difficult thoroughly choosing of ten or twenty layer screening, time-consuming power consumption, poor effect, the Shi Mizhong that dispatches from the factory has paddy, and the consumer is difficult to accept.

Summary of the invention

The purpose of this utility model is improved at shortcoming that exists in the background technology and problem, and a kind of technology advanced person is provided, and cost is low, especially Shi Yong efficient grain rough separating screen plate.

The technical scheme that realizes the utility model purpose is: the gravity according to grain and brown rice is different, utilize grain and the brown rice of inclined-plane boss in will vibrating to separate, it is surface with the sieve plate matrix boss that evenly is being staggered, the bottom of boss is rectangle or other abnormity, the length direction of rectangle boss projection two asymmetric inclined-planes wherein, facade behind boss front bevel and the boss, the end face that width projection two symmetries tilt.

The utility model change former on steel plate the different apertures of punching press carry out paddy, rough separation processes with sieve aperture, grain is different owing to gravity with brown rice in the vibration, by the inclined-plane boss it is separated, because grain band shell, proportion is lighter, can make progress away by the inclined-plane boss, grain of rice proportion is heavier, can not enter boss, can only below walk, by the discharging opening that is contained in the frame upper/lower terminal it is separated fully, vibration force is provided by the vibrating motor that is contained on the frame, this sieve plate paddy, rough separative efficiency height separate thoroughly energy-conservation practicality.

The specific embodiment

By Fig. 1,2,3 as can be known, the utility model is with the surface of sieve plate matrix (1) boss (2) that evenly is being staggered, the bottom of boss (2) is rectangle or other abnormity, the length direction of rectangle boss projection two asymmetric inclined-planes wherein, facade (4) behind boss front bevel (5) and the boss, the end face (3) that width projection two symmetries tilt.

Boss described in the utility model (2) front bevel (5) forms a α angle with the vertical plane of sieve plate matrix (1), and back facade (4) forms the δ angle less than the α angle with the vertical plane of sieve plate matrix (1).The both ends of the surface (3) of described boss (2) and the vertical plane of sieve plate matrix (1) form the β angle of a symmetry.The utility model improves more than ten times than former different apertures round-hole mesh efficient; Improved rice quality, can be with paddy, rough thorough separation, former sieve plate is not accomplished; Can save energy more than 50%; Can reduce unit, sieve plate cost 30%.

Claims
