TECHNICAL FIELD

[0001] The utility model relates to a shelling equipment technical field, specifically a rice sheller impurity removal mechanism. BACKGROUND

[0002] Rice is a genus of cereal crops, and the ancestors of the Yangtze River Basin have planted rice. Rice is divided into indica rice and japonica rice, early rice and mid-late rice, waxy rice and non-waxy rice according to the type of rice. According to the seed saving method, it is divided into conventional rice and hybrid rice. The fruit of rice is rice, and nearly half of the world's population relies on rice as their main food. After the hull of the rice is removed, it is called brown rice. Brown rice can be milled to obtain rice by removing the bran layer. A rice sheller is usually used during the shelling process.

[0003] The main function of the rice sheller is to separate brown rice and chaff. However, the rice entering the sheller may contain stones, soil, immature seeds, and straw. In order to improve the quality of the rice and reduce the wear and tear of the internal parts of the sheller, it is necessary to remove these impurities. Therefore, an impurity removal mechanism needs to be added to the sheller. SUMMARY

[0004] The utility model aims at providing a rice sheller impurity removal mechanism to solve the problems raised in the background.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] A shelling and separating mechanism, which includes a round shell, a support box fixedly connected to the bottom of the round shell, and a feed hopper fixedly connected to the top of the round shell.

[0008] An impurity removal mechanism, which is fixedly arranged inside the support box. The impurity removal mechanism includes a protective cover fixedly connected to the round shell, a fan rotatably connected to the inside of the protective cover, a double-shaft motor fixedly connected to the center position of the protective cover, an output shaft of the double-shaft motor fixedly connected to one end of the fan, a synchronous pulley one fixedly sleeved to the other end of the output shaft of the double-shaft motor, one end of a synchronous belt fixedly sleeved to the synchronous pulley one, the other end of the synchronous belt fixedly sleeved to a synchronous pulley two, a rotating shaft two fixedly sleeved to the synchronous pulley two, a cam fixedly sleeved to the rotating shaft two, a lifting plate abutting the bottom of the cam, and a vibrating frame fixedly connected to the end of the lifting plate.

[0009] Further, the shelling and separating mechanism includes:

[0010] Two husking rollers, which are rotatably connected to the round shell.

[0011] Rotary shafts are arranged with two, which are fixedly sleeved with the center positions of the shelling rollers;

[0012] Spur gears are arranged with two, which are fixedly sleeved with the end portions of the rotary shafts and are meshingly connected between the two spur gears;

[0013] A driving motor is fixedly connected with the rotary shafts at the output end.

[0014] Further, the shelling and separating mechanism comprises:

[0015] Sub-rollers are arranged with two, which are located on one side of the shelling roller and are rotatably connected with the round shell.

[0016] Further, the shelling and separating mechanism comprises:

[0017] A square tube is fixedly connected with the side wall of the round shell;

[0018] A shell collecting box is oppositely connected with the square tube;

[0022] Further, a plurality of shell separating plates are fixedly connected with the inner wall of the round shell at equal distances, and a plurality of inclined plates are fixedly connected with the opposite outer walls of the shell separating plates at equal distances.

[0023] Further, the impurity removing mechanism comprises:

[0024] Inclined plates are fixedly connected with the bottom of the vibrating frame;

[0025] Strip-shaped sieve holes are equidistantly arranged on the inclined plates;

[0026] A baffle is fixedly connected with the end portion of the vibrating frame;

[0027] A pouring plate is fixedly connected with the side wall of the vibrating frame.

[0028] Further, the impurity removing mechanism comprises:

[0029] Sleeving blocks are arranged with two, which are fixedly connected with the side wall of the vibrating frame;

[0030] Limiting columns are arranged with two, which are slidingly sleeved with the sleeving blocks;

[0031] Two buffer springs are provided and are sleeved on the outside of the limiting column.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] 1. Pour the rice from the feed hopper into the hulling and separation mechanism, and then drive the rotating shaft to rotate through the driving motor, so as to drive the two spur gears to engage and rotate, and then drive the two hulling rollers to rotate in opposite directions through the rotating shaft. When the rice passes through the hulling rollers, it will be rubbed by the two hulling rollers, so that the rice grains and husks are separated, and then it will fall onto the hull separating plate and collide with it, which helps to further separate the husks, and then the fan is driven to rotate by the output end of the dual-axis motor, so that air flow can pass through the round husks, making it easier to blow the lighter husks into the square cylinder, and then they will be collected in the hull collecting box. The two ends of the hull collecting box are connected by a limit rod and a sleeve ring, so that the hull collecting box can be lifted and removed for cleaning. The hulling and separation mechanism can speed up the efficiency of rice husking.

[0034] 2. The hulled brown rice and impurities will fall into the vibrating frame, and the output end of the dual-axis motor will drive the synchronous pulley 1 to rotate, and then the synchronous belt will drive the synchronous pulley 2 to rotate synchronously. The synchronous pulley 2 drives the rotating shaft 2 and the cam to rotate, and the protruding end of the cam will push the lifting plate and the vibrating frame to move downward. When the cam rotates to the point where the protruding end and the top surface of the lifting plate are completely separated, the buffer spring will squeeze the vibrating frame and quickly bounce back to its original position, so that the vibrating frame will continue to vibrate as the cam rotates. The vibration can shake the brown rice off the strip sieve holes, while impurities such as straw, stones and soil will be sieved out. As the vibration occurs, the impurities will gradually move along the inclined surface and roll to the pouring plate. The provision of a baffle can prevent the brown rice from rolling to the outside.
