[0019] The technical solutions of the present application will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0020] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0021] As shown in Figures 1 to 5 The present embodiment discloses a rice production impurity removal device, which comprises a box body 1, a filter cavity 101 is formed inside the box body 1, and an inlet 2 and an outlet 3 are respectively arranged on the top and bottom of the box body 1 and communicate with the filter cavity 101. Two screen plates 4 are arranged in the filter cavity 101 in a vertical direction and are spaced apart, and the screen plates 4 are provided with screen meshes 41, the screen meshes 41 of each screen plate 4 have different screening accuracies, for example, the screen meshes 41 of the upper screen plate 4 have a larger aperture than the lower screen plate 4, so as to realize multi-stage filtering and improve the impurity removal effect on rice. When the rice is filtered, the rice can move in different directions transversely along the screen plates 4 after passing through the two screen plates 4 in turn, so as to ensure that the filtering of the rice is more sufficient, and the two reciprocating screen plates 4 can form dynamic screening, and the screen plates 4 can be inclined to a certain extent during movement, so as to effectively avoid the screen holes of the screen meshes 41 being blocked during the filtering of the rice, and improve the processing efficiency. Therefore, in order to avoid the rice from separating from the screen meshes 41 during the sliding process due to the inclination of the screen plates 4, a fence is further fixed outside the screen meshes 41 to limit the rice.

[0022] In the present embodiment, a guide opening 102 is further arranged through the side wall of the box body 1, the outer side end portions of the two screen plates 4 extend to the guide opening 102 of the side wall of the box body 1, the guide opening 102 is a long strip-shaped through hole and forms a sliding fit with the end portions of the screen plates 4, so that the screen plates 4 can guide the movement of the screen plates 4 during movement, and ensure that the screen plates 4 move stably in the horizontal direction. In addition, since the screen plates 4 are moved transversely by the rotary movement of the connecting arms 5 described below, the screen plates 4 will float in the vertical direction during movement, so the height of the guide opening 102 needs to be set to be greater than the height of the outer side end portions of the screen plates 4, so as to avoid interference with the screen plates 4 during movement of the screen plates 4.

[0023] In the embodiment, the structure that the two sieve plates 4 move towards each other or move away from each other is that a connecting arm 5 is rotatably connected to the inner wall of the box 1 through a bearing, the two ends of the connecting arm 5 are rotatably connected to the outer walls of the two sieve plates 4 respectively, a connecting end 51 extending outward is arranged at the center of the connecting arm 5, and a driving mechanism is connected to the connecting end 51, which is used to drive the connecting arm 5 to reciprocate rotationally, so as to drive the two sieve plates 4 to reciprocate towards each other or move away from each other.

[0024] The specific structure of the driving mechanism comprises a transmission conical gear 61 and a driving conical gear 62, the transmission conical gear 61 is symmetrically sleeved and fixed on the connecting end 51, and the driving conical gear 62 is provided with partial teeth 621. A driving motor 63 is connected to the center of the driving conical gear 62, which is used to drive the driving conical gear 62 to rotate, so that the partial teeth 621 of the driving conical gear 6 are alternately meshed with each transmission conical gear 61. When meshing, the connecting arm 5 produces reciprocating swing, thereby driving the two sieve plates 4 to move linearly towards each other or move away from each other along the guide opening 102. In this process, the reciprocating movement of the two sieve plates 4 makes the rice continuously roll on the surface of the screen 41, improves the impurity separation efficiency and prevents the screen hole from being blocked, and the structure only needs a single driving motor 63 to drive the two sieve plates 4 to move towards each other or move away from each other at the same time, so as to reduce the overall installation cost.

[0025] In order to adapt to different filtering needs, the screen 41 on the sieve plate 4 adopts a detachable design. Specifically, an installation opening is formed on the sieve plate 4, a connecting plate 7 with a first threaded hole is welded on the inner side of the installation opening, a frame 411 is arranged on the outer periphery of the screen 41, and a second threaded hole 411a opposite to the first threaded hole is arranged on the frame 411. By opposing the second threaded hole 411a to the first threaded hole and rotating a locking piece threaded with the first threaded hole and the second threaded hole 411a, the sieve plate 4 and the screen 41 can be fixed to each other, so that the screen 41 can be conveniently disassembled and assembled, and the impurities on the screen 41 can be cleaned.

[0026] Work flow: When working, the worker pours the rice from the feeding opening 2 into the filtering cavity 101, and first falls on the screen 41 of the upper sieve plate 4. The sieve plate 4 is driven by the driving mechanism to move reciprocally, and the large-particle impurities are intercepted on the surface of the screen 41 of the upper sieve plate 4. The rice meeting the size falls to the screen 41 of the lower sieve plate 4 for secondary filtering. After two-stage screening, the clean rice is discharged from the discharging opening 3, and the impurities are retained on the screen 41 and removed by manual cleaning subsequently.

[0027] The specific embodiment is only an explanation of the utility model, and is not a limitation of the utility model. Those skilled in the art can make modifications to the embodiment without creative contribution after reading the specification, but as long as it is within the scope of the claims of the utility model, it is protected by the patent law.
