Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-Figure 4 A rice production and selection grading device includes a body 1, a cavity is opened in the body 1, and the body 1 is provided with: a first rotating plate 2, a second rotating plate 6, a first telescopic rod 3 and a second telescopic rod 7, as shown in the attached Figure 3 As shown, the first rotating plate 2 and the second rotating plate 6 are arranged in the cavity to rotate in an upward and downward order, and the first telescopic rod 3 and the second telescopic rod 7 are fixedly mounted on the upper ends of the first rotating plate 2 and the second rotating plate 6 respectively;

[0030] The body 1 is also provided with: a first upper plate 4, a second upper plate 8, a first filter hole 5 and a second filter hole 9, as shown in the attached Figure 3 As shown, the first upper plate 4 and the second upper plate 8 are fixedly connected to the output end of the first telescopic rod 3 and the output end of the second telescopic rod 7 respectively, and the first upper plate 4 and the second upper plate 8 are shaken up and down by the first telescopic rod 3 and the second telescopic rod 7 respectively. At the same time, the first filter hole 5 is opened on the first rotating plate 2 and the first upper plate 4, and the second filter hole 9 is opened on the second rotating plate 6 and the second upper plate 8, so that the rice passes through the first filter hole 5 twice and the second filter hole 9 twice, increasing the number of rice screenings, and the diameter of the first filter hole 5 is much larger than the diameter of the second filter hole 9, and then under the accelerated screening of the first upper plate 4 and the second upper plate 8 that are shaken up and down, the first filter hole 5 and the second filter hole 9 perform three-level screening processing on the rice, so that large particles, medium particles and small particles of rice are separated;

[0031] The machine body 1 is further provided with: a collecting assembly, which is arranged on the machine body 1 and is used to collect the rice after the three-stage screening in sequence, that is, to collect large-grain, medium-grain and small-grain rice respectively; a driving mechanism, which is arranged on the machine body 1 and is used to adjust the inclination angles of the first rotating plate 2 and the second rotating plate 6 to control the rice screening time. If the rice needs to be finely screened, the inclination angles of the first rotating plate 2 and the second rotating plate 6 are reduced, the rice sliding speed is reduced, and the rice screening time is increased; if the rice needs to be roughly screened, the inclination angles of the first rotating plate 2 and the second rotating plate 6 are increased, the rice sliding speed is increased, and the rice screening time is reduced;

[0032] A feed port 10 communicating with the cavity is provided at the upper end of the machine body 1 , and the feed port 10 is located above the first upper plate 4 , through which rice can be poured into the cavity for screening, and a cleaning port 14 is provided at the lower end of the machine body 1 .

[0033] The collection assembly includes: a side opening 11, a collection trough 12, an inclined guide plate 13 and a lower end receiving box 15, as shown in the attached Figure 1 As shown, two side openings 11 are opened at the side ends of the body 1 in an upper and lower order, two collecting troughs 12 are fixedly connected to the lower ends of the two side openings 11, and four inclined guide plates 13 are fixedly connected to the first rotating plate 2, the first upper plate 4, the second rotating plate 6 and the second upper plate 8, and the inclined guide plates 13 are tilted downward to guide the rice to slide downward, and the lower end storage box 15 is fixedly installed at the lower end of the cavity.

[0034] The collection component also includes: Figure 3 As shown, the two upper inclined guide plates 13 extend out of the cavity through the upper side opening 11, and the two lower inclined guide plates 13 extend out of the cavity through the lower side opening 11. The two upper inclined guide plates 13 guide large-grain rice into the upper collecting trough 12, and the two lower inclined guide plates 13 guide medium-grain rice into the lower collecting trough 12.

The driving cylinder 21 allows the movable rack 22 to move up and down linearly, and the first rotating shaft 16 is located at one end in the cavity and the second rotating shaft 17 is located at one end in the cavity and is fixedly connected to the first rotating plate 2 and the second rotating plate 6 respectively. At the same time, the movable rack 22 is meshed with the first gear 18 and the second gear 19 at the same time, and the first rotating plate 2 and the second rotating plate 6 are deflected at the same time.

[0037] The functional principle of this utility model can be explained through the following operation modes:

[0038] First, start the driving cylinder 21, and let the output end of the driving cylinder 21 drive the moving rack 22 to move up and down linearly.

The first telescopic rod 3 and the second telescopic rod 7 are started to make the first upper plate 4 and the second upper plate 8 shake up and down, thereby accelerating the screening, and the rice slides downward along the first upper plate 4 and the first rotating plate 2, and large grains of rice are intercepted by the first filter hole 5, while medium and small grains of rice fall onto the second upper plate 8, and medium grains of rice are intercepted by the second filter hole 9, while small grains of rice fall into the storage box 15 at the lower end.
