[0002] Rice is composed of husk, cortex, embryo and endosperm. The purpose of rice processing is to separate the endosperm from other parts with the least degree of crushing to make rice with better edible quality.

[0003] In the process of realizing the utility model, the inventors found that there are at least the following problems in the technology: during the rice processing process, rice with different particle sizes needs to be graded and selected (whole and intact rice is larger particles, and damaged and broken rice is smaller particles), so that rice with different particle sizes can be processed separately. When the current rice grading and selection device is in operation, it is usually not convenient to automatically grade and discharge rice with different particle sizes, and some operations need to be performed manually, which is relatively troublesome.

[0004] Therefore, we propose a rice processing, grading and selecting device to solve the above problems. Utility Model Content

[0008] As a preferred embodiment, the two inner support shafts are both horizontally arranged and symmetrically arranged on both sides of the bracket, and the two inner support shafts are both rotatably connected to the selection tank; so that the two inner support shafts can operate stably and drive the bracket to flip.

[0009] As a preferred embodiment, the bracket is U-shaped, and a hood is welded on the side where the second motor is located, wherein the hood is sleeved on the outside of the second motor; thereby the hood is used to protect the second motor, and both the first motor and the second motor require power supply from external power facilities.

[0010] As a preferred embodiment, the upper support shaft is vertically arranged and rotatably connected to the top wall of the bracket, so that both the upper support shaft and the grading disk can operate stably.

[0011] As a preferred embodiment, the multiple groups of grading holes are distributed in a circular array along the central axis of the grading disk, and some of the grading holes pass through the guide slope; so that when the grading disk is in operation, the rice can be thrown toward the guide slope, thereby throwing small particles of rice out of the grading holes.

[0012] As a preferred embodiment, guide slopes are provided on both sides of the inner cavity of the selection tank, and the ends of the two guide slopes lead to the discharge port, so that the rice can be discharged from the discharge port more quickly under the guidance of the guide slopes.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3 A rice processing and grading and selecting device comprises a selecting tank 1 and a grading and selecting mechanism located in the inner cavity of the selecting tank 1, support feet 14 are installed at the four corners of the bottom wall of the selecting tank 1, a feeding pipe 2 is welded integrally at the center of the top wall of the selecting tank 1, and a first motor 3 is horizontally installed on one side wall of the selecting tank 1, inner support shafts 4 are respectively arranged on both sides of the inner cavity of the selecting tank 1, an output shaft of the first motor 3 is coaxially connected with one of the inner support shafts 4, and a bracket 5 is welded between the two inner support shafts 4, the two inner support shafts 4 are both horizontally arranged and symmetrical to the two sides of the bracket 5, and the two inner support shafts 4 are both rotatably connected to the selecting tank 1, so that the two inner support shafts 4 can operate stably and drive the bracket 5 to flip;

[0021] The grading and selecting mechanism includes a second motor 6 installed on the bottom wall of the bracket 5, an upper support shaft 8 coaxially connected to the output shaft of the second motor 6, and a grading disk 9 welded on the upper support shaft 8. The bracket 5 is U-shaped, and a hood 7 is welded on the side of the bracket 5 where the second motor 6 is located, wherein the hood 7 is sleeved on the outside of the second motor 6, so that the hood 7 is used to protect the second motor 6. The first motor 3 and the second motor 6 both need to be powered by external power facilities, wherein the upper support shaft 8 and the grading disk 9 are designed to be coaxial, and the upper support shaft 8 is vertically arranged and rotatably connected to the top wall of the bracket 5, so that the upper support shaft 8 and the grading disk 9 can both operate stably;

[0022] A guide slope 10 is formed on the top wall of the grading disk 9 toward the inside thereof, and a plurality of groups of grading holes 11 penetrating to the bottom wall thereof are drilled in the grading disk 9 in the vertical direction. The plurality of groups of grading holes 11 are distributed in a circular array along the central axis of the grading disk 9, and some of the grading holes 11 pass through the guide slope 10, so that the grading disk 9 can throw the rice toward the guide slope 10 when it is in operation, thereby throwing small-grained rice out of the grading holes 11, so that the rice with smaller grains can be sorted out and discharged first through the plurality of groups of grading holes 11, and a discharge port 13 communicating with the inner cavity of the selection tank 1 is provided on the bottom wall of the selection tank 1, so that the rice is discharged through the discharge port 13, and guide slopes 12 are provided on both sides of the inner cavity of the selection tank 1, and the ends of the two guide slopes 12 lead to the discharge port 13, so that the rice can be discharged from the discharge port 13 more quickly under the guidance of the guide slopes 12.

With the operation of the grading disk 9, the rice will be thrown to the guiding slope 10. At the same time, since the rice is in a moving state, the smaller particles in the rice will be more easily discharged through the grading holes 11, and discharged from the discharge port 13 under the action of the guiding slope 12, so that the smaller particles of rice are quickly sorted out and discharged; then the second motor 6 is kept running, and the first motor 3 is operated to drive the bracket 5 and the two inner support shafts 4 to flip, so that the grading disk 9 is flipped more than 90°, so that the larger particles of rice remaining in the grading disk 9 can be poured out and discharged from the discharge port 13 (it should be noted during actual manufacturing that the grading disk 9 cannot conflict with the inner wall and other structures of the selecting tank 1 when flipping).
