Further, the material conveying screw rod rotates through a rotating motor A fixed on the hopper cover, automatic material conveying to the screening box body through the material conveying screw rod is achieved, and meanwhile the hopper is prevented from being blocked.
Further, even unloader is narrow down wide toper post, even unloader fixes the lower terminal surface at defeated material screw rod, defeated material screw rod exports the material from the hopper in, the slope terminal surface of even unloader can be followed to the material of output is scattered, simultaneously because even unloader can rotate along with defeated material screw rod, so the material can get rid of to remove in the stone screening plant with certain inclination behind the unloading of even unloader and carry out the screening, the material of whereabouts will disperse in removing the stone screening plant terminal surface like this, prevent that the material from directly falling to the impurity discharge gate that removes stone screening plant, by the discharge.
Further, the stone removing and screening device is a conical cylinder with a wide upper part and a narrow lower part, and is rotationally fixed in the screening box body through a sliding ring connected with a horizontal rod, so that the stone removing and screening device can rotate in the screening box body under the driving of a transmission device.
Further, even unloader is located and removes stone screening plant, prevents that the material from being thrown away stone screening plant or directly getting rid of to remove the impurity discharge gate of stone screening plant.
Further, the bottom face of screening box inclines, the discharge of the material of being convenient for, and the screening box is equipped with the material and collects the mouth.
To sum up, the beneficial effects of this application: according to the device, the centrifugal sedimentation principle is utilized to separate stone, sand and other impurities in rice, and the centrifugal sedimentation device is difficult to separate because of larger collision friction force when separating solid-solid materials, so that the device uniformly and slowly conveys the materials to the inner end surface of the stone removing and screening device for screening through centrifugation during discharging, and the working efficiency is greatly improved; because the device has simple structure and low manufacturing cost, the device is convenient for subsequent maintenance.
