Technical Field

Background

A rice mill is a machine for milling and husking grains. The traditional rice mill has single function and only has the rice milling and husking functions. In the process of processing grains, in order to meet better rice milling and husking effects, impurities are generally removed from the grains before the grains are put into a rice mill. However, this process is generally performed manually or by a separate device. This approach is inefficient and costly. Some rice mills have separate impurity removal assemblies for removing impurities from grain. However, the impurity removal effect of the components is not good, and the requirement of subsequent rice milling and husking can be met by removing impurities for many times.

Detailed Description

The utility model will be described in further detail with reference to the following drawings and specific embodiments.

As shown in fig. 1-2, a three-layer grain sieve of a vibrating screen rice mill comprises a sieve frame 501, a coarse impurity screen 502 which is obliquely arranged is arranged inside the sieve frame 501, a coarse impurity discharge hole 503 which is communicated with the coarse impurity screen 502 is arranged at a position on the outer side wall of the sieve frame 501 corresponding to the lower end of the coarse impurity screen 502, a grain screen 504 is arranged at a position below the coarse impurity screen 502 inside the sieve frame 501, the grain screen 504 is obliquely arranged and has the same oblique direction as the coarse impurity screen 502, the mesh size of the coarse impurity screen 502 is larger than that of the grain screen 504, a gap 505 is arranged between the lower end of the grain screen 504 and the inner side wall of the sieve frame 501, a grain discharge hole 506 is arranged at a position on the lower surface of the sieve frame 501 corresponding to the gap 505, a fine impurity baffle 507 whose oblique direction is opposite to the grain screen 504 is arranged at a position below the grain screen 501, the fine impurity baffle 507 is connected with the grain screen 504, the fine impurity baffle 507 is obliquely arranged and the oblique direction is opposite to the grain screen 504, and a fine impurity discharge hole 508 communicated with the fine impurity baffle 507 is arranged at the position, corresponding to the lower end of the fine impurity baffle 507, of the outer side wall of the screen frame 501.

In this embodiment, the coarse impurity screen 502 and the grain screen 504 are inclined at the same angle.

In this embodiment, the higher end of the fine impurity barrier 507 is connected to the lower end of the grain screen 504.

In this embodiment, the higher end of the fine impurity barrier 507 and the lower end of the grain sieve 504 are connected by a fine impurity connecting plate 509.

The three-layer grain sieve is not limited to a rice mill and can be used for other machines needing sieving functions. And the power can be matched for independent use.

The coarse impurity screen 502 of the three-layer grain screen has a mesh opening size set to allow most of the grains 511 and the fine impurities 512 to pass through. The grain sieve 504 has a mesh aperture set to a size that blocks the grains 511 and allows the fine impurities 512 to pass through. During operation, grains 511 containing impurities are fed into the screen frame 501, and the three-layer grain screen 5 operates under the driving of the power of the rice mill. The grains 511 containing impurities fall onto the coarse impurity screen 502, the coarse impurity screen 502 has screen holes through which the grains 511 and the fine impurities 512 pass, and the coarse impurities 510 which cannot pass are discharged from the coarse impurity discharge port 503 by the vibration of the three-layer grain screen 5. The grain 511 containing the fine impurities 512 falls onto the grain sieve 504, and since the mesh opening of the grain sieve 504 is set to a hole diameter capable of blocking the grain 511 and allowing the fine impurities 512 to pass, the fine impurities 512 fall onto the fine impurity baffle 507 through the mesh opening of the grain sieve 504, and are discharged from the fine impurity discharge port 508. The grains which do not pass through the grain sieve 504 are discharged from the grain 511 discharging port 506 by the vibration of the three-layer grain sieve 5.

In order to achieve a better screening effect, the outer side of the coarse impurity screen 502 is hermetically connected with the inner side wall of the screen frame 501. The higher end of the grain sieve 504 and the two side surfaces adjacent to the higher end are hermetically connected with the inner side wall of the sieve frame 501. The fine impurity baffle 507 and the two side faces adjacent to the higher end thereof are hermetically connected with the inner side wall of the screen frame 501.

The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
