Description

A specific gravity separator for small grains

Technical Field

The utility model relates to the technical field of grain sorting, in particular to a specific gravity sorting machine for small grains.

Background Art

After harvest, grains usually need to be cleaned before they can be stored. Grain cleaning usually uses a gravity sorter, which can separate materials into heavy materials, light materials, large impurities and light impurities. The main structure of a traditional gravity sorter includes an inclined vibrating screen driven by a vibrating motor, an air suction hood is arranged on the upper part of the vibrating screen, the air suction hood is connected to the air suction pipe and the feed box respectively, a grain collection box and an impurity collection box are respectively arranged at the lower part of the vibrating screen, and an angle adjustment mechanism is also arranged at the lower part of the vibrating screen. However, the traditional gravity sorter can only adjust the inclination angle of the vibrating screen, but cannot adjust the height of the vibrating screen. Therefore, the vibrating screen can only be installed on a seat with a fixed height, which has great limitations.

After searching, a grain specific gravity separator disclosed in the prior art (application number: CN201521012458.5) records that "the height adjustment structure includes a retractable support rod arranged in the middle of the vibrating screen and vertical mounting plates respectively arranged on both sides of the vibrating screen, threaded holes are opened on the outer sides of the vertical mounting plates, and brackets are respectively provided on both sides of the vibrating screen, and vertical strip holes are opened on the brackets. T-shaped bolts are threadedly connected in the threaded holes, and the rod of the T-shaped bolt passes through the strip hole, and the inner side of the head of the T-shaped bolt is pressed against the outer side of the bracket". The gravity separator loosens the T-bolt to separate the inner side of the T-bolt from the outer side of the bracket, and then moves the T-bolt, the vertical mounting plate and the vibrating screen upward or downward along the strip holes on the bracket. When the height meets the requirement, the T-bolt is tightened again to press the inner side of the T-bolt head against the outer side of the bracket to complete the adjustment of the vibrating screen height. However, the gravity separator only performs one sorting process on the grain, resulting in poor sorting effect and failure to effectively sort grains of different sizes. The grains then need to be sorted a second time, thereby reducing the grain sorting efficiency.

In this embodiment, the switches of the blowing assembly 2 and the vibrator 6 are first started in sequence, and the vibrator 6 drives the sieve plate 12, the sieve plate 2 15 and the sieve plate 3 16 to vibrate synchronously through the horizontal plate 1 7 and the fixed frame 3, and then the grain to be sorted is put into the box body 1 through the feed hopper 9, and the large-sized and light-weight debris in the grain will be retained on the surface of the sieve plate 12, and under the action of the airflow blown by the blowing assembly 2, the debris will fall into the discharge plate 13 through the discharge port, and then discharged from the box body 1, and the grain after the preliminary filtration will be screened for the second time on the surface of the sieve plate 2 15, wherein the smaller-sized grain and the smaller-sized debris will fall on the sieve plate 3 16 The surface of the sieve plate three 16 intercepts the grain, so that the debris two falls into the waste box 5, and the grain on the surface of the sieve plate three 16 will fall into the discharge plate three through the discharge port three, and then be discharged from the box body 1.
