Embodiment

[0025] A specific gravity stoner for rice, basically as attached figure 1 , attached figure 2 And attached image 3 Shown, comprise collection box 1 and be positioned at the separating barrel 2 in collecting box 1, be provided with annular groove on the outer wall of the top of separating barrel 2, be provided with guide rod 5 in collecting box 1, guide rod 5 is two . One end of the guide rod 5 is fixed on the collection box 1, and the other end of the guide rod 5 extends into the groove and is slidably connected with the groove, so that the collection box 1 and the separation bucket 2 can rotate relatively, and the side of the separation bucket 2 Separation holes 8 are provided on the wall. When the separation barrel 2 rotates, the guide rod 5 limits the separation barrel 2 to prevent the separation barrel 2 from shifting under the action of centrifugal force when the separation barrel 2 rotates.

[0026] An air motor 3 is arranged above the collecting box 1 , and a driv...

Abstract

The invention relates to the technical field of separating device assembly of separating solid by screening or sieving or using gas flow, and discloses a specific-gravity stoner for rice. The specific-gravity stoner for rice comprises a collecting box and a separating barrel, and further comprises a fan, wherein a separating hole is formed in the side wall of the separating barrel; a pneumatic motor is fixedly arranged above the collecting box; a drive part is fixedly arranged below the collecting box; the separating barrel is fixedly connected to the output shaft of the drive part; a separating shaft is rotatably connected in the separating barrel; the separating barrel is fixedly connected to the output shaft of the pneumatic motor; the periphery of the separating shaft is fixedly equipped with a packing auger; the blade of the packing auger is gradually reduced from bottom to top; a negative-pressure section and a dust-removal section which communicates with the negative-pressure section are arranged in the separating shaft; a gas hole which communicates with the negative-pressure section is formed in the side wall of the separating shaft; a gas outlet of the pneumatic motor communicates with the negative-pressure section; the dust-removal section communicates with outside air; and a gas outlet of the dust-removal section is positioned above the gas inlet of the negative-pressure section. According to the scheme adopted by the invention, the specific-gravity stoner is simple in structure, and conveniently removes gravels and sediments in grains.

Description

technical field [0001] The invention relates to the technical field of screening or sieving, or separating solids from solids by means of air flow, in particular to a specific gravity destoner for rice. Background technique [0002] The specific gravity de-stoner machine is a machine that separates heavy impurities such as grain and sand according to the specific gravity of grain (rice) and sand. The specific gravity stoner has the advantages of good stone removal effect, simple structure, small size and low energy consumption. After the grain is cleaned by the specific gravity stoner, the stone removal rate is about 95%. [0003] Chinese patent announcement number is: the utility model of CN203437331U, discloses a kind of specific gravity destoner, comprises machine tool, is arranged on the suction hood above the machine tool, is arranged on the vibrating motor below the machine tool or on either side of front and rear sides, through spring and The frame connected to the m...
