[0031] As shown in the Figure 1 embodiments of the present application provide a rice processing equipment for removing impurities, including the machine box 1, the lower end surface of the machine box 1 is fixed with a plurality of supporting legs 101, one end of the machine box 1 is provided with a fan mechanism, the other end is provided with an air outlet, the upper end surface of the machine box 1 is fixed with a feeding hopper 2, the lower end surface of the machine box 1 is provided with a first impurity discharge hopper 3, a rice discharge hopper 4 and a second impurity discharge hopper 5. As shown in the Figure 4 the upper end surface of the first impurity discharge hopper 3, the rice discharge hopper 4 and the second impurity discharge hopper 5 are sequentially arranged on the bottom surface of the machine box 1 towards the air outlet end, the lower end of the first impurity discharge hopper 3, the rice discharge hopper 4 and the second impurity discharge hopper 5 all extend out of the lower end surface of the machine box 1, and the lower end of the rice discharge hopper 4 is towards the lower side of the machine box 1, and the lower end of the first impurity discharge hopper 3 and the second impurity discharge hopper 5 is towards the other side of the lower side of the machine box 1.
[0032] As shown in the Figure 2As shown, the fan mechanism inside the casing 1 includes a rotating shaft 8, which is rotatably mounted inside the end of the casing 1. Fan blades 801 are mounted on the rotating shaft 8. One end of the rotating shaft 8 extends outward from the casing 1 and is fixed to a drive wheel 802. A motor 9 is fitted to the end of the rotating shaft 8 away from the drive wheel 802. The motor 9 is fixed to the outside of the casing 1, and its shaft is fixed to the end of the rotating shaft 8. Therefore, the rotating shaft 8 can be driven to rotate by the motor 9, causing the fan blades 801 to blow air. This allows rice falling from the feed hopper 2 to be separated by air, with good quality rice falling into the rice discharge hopper 4, and impurities heavier or lighter than rice falling into the first impurity discharge hopper 3 and the second impurity discharge hopper 5, respectively.
[0033] In addition to Figure 3 As shown, a reciprocating screw 6 is rotatably mounted on the top of the chassis 1. One end of the reciprocating screw 6 is fixed with a driven wheel 601. A transmission belt is sleeved between the driven wheel 601 and the driving wheel 802, so that when the rotating shaft 8 drives the fan blade 801 to blow air, it can also drive the reciprocating screw 6 to rotate.
[0034] A horizontal control plate 7 is slidably installed inside the feed hopper 2. The middle part of the control plate 7 has a discharge port 702 that connects the machine box 1 and the inside of the feed hopper 2. A slider 701 that extends horizontally out of the bottom of the feed hopper 2 is fixed on one side of the control plate 7. The slider 701 is threaded onto the reciprocating screw 6, so that the control plate 7 can reciprocate inside the feed hopper 2.
[0035] In specific implementation, the bottom side of the feed hopper 2 is provided with a strip groove for the slider 701 to slide horizontally out, and the bottom ends of the feed hopper 2 are provided with openings for the two ends of the control plate 7 to pass through respectively. The control plate 7 slides horizontally in the feed hopper 2 along its length direction, and the length of the control plate 7 is at least twice the length of the inner long side of the feed hopper 2.
[0036] The working principle of this utility model is as follows: When using this rice processing impurity removal equipment, rice can be placed in the feeding hopper 2. By starting the motor 9, the rotating shaft 8 is driven to rotate. The rotating shaft 8 drives the fan blades 801 to blow air inside the machine housing 1. At the same time, the drive wheel 802 at the end of the fan blades 801 drives the driven wheel 601 to rotate the reciprocating screw 6 through the transmission belt, thereby controlling the material control plate 7 to move back and forth in the feeding hopper 2. This allows the rice in the feeding hopper 2 to fall quickly and evenly from different positions on the top of the machine housing 1 through the movable discharge port 702. This not only ensures the feeding speed and air separation efficiency, but also avoids excessive feeding at one point, thus ensuring the air separation effect. In addition, this device can control the blowing and uniform feeding with a single motor 9, which is beneficial for energy saving.
