[0030] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0031] Please refer to the attached drawing, which is a structural schematic diagram of a preferred embodiment of a bran removal system and rice milling and polishing equipment provided by the present invention.

[0032] A bran discharge system, used for discharging residues generated by a rice milling and polishing device, comprises:

[0033] A residue collection chamber 6 is provided in the main body 1 of the rice milling and polishing device. The residue collection chamber 6 is used to collect the residue in the main body 1. An exhaust port is provided on the outer wall of the residue collection chamber 6. The exhaust port is connected to the exhaust device 5. The exhaust device 5 is used to extract the residue in the residue collection chamber 6.

[0034] A rotatable cleaning assembly 7 is arranged in the residue collection chamber 6, and the cleaning assembly 7 is used to break up the residue in the residue collection chamber 6 and push it to the discharge port.

[0035] The utility model collects the residue in the main body 1 through the residue collecting chamber 6. The outer wall of the residue collecting chamber 6 is provided with a discharge port, and the discharge port is connected to the vacuum device 5, so that the residue in the residue collecting chamber 6 is extracted by the vacuum device 5 to carry out the bran discharge process; in addition, a rotatable cleaning component 7 is provided in the residue collecting chamber 6 to break up the residue in the residue collecting chamber 6 and push it to the discharge port, which can further reduce the resistance to the discharge of the residue and effectively improve the efficiency of bran discharge.

[0036] Preferably, please refer to Figure 1 and Figure 2 As shown, the cleaning assembly 7 includes a rotating member 704, and a first cleaning member 705 and a second cleaning member 706 are arranged in an annular array on the outer wall of the rotating member 704. The first cleaning member 705 and the second cleaning member 706 are used to break up the residue and push the residue to the discharge port.

[0037] It is understandable that simply relying on the external vacuum device 5 to extract the residue will result in a large resistance to bran discharge, so a cleaning component 7 is provided in the residue collection chamber 6 to break up the residue and then more smoothly extract the residue through the vacuum device 5 .

[0038] Preferably, please refer to Figure 3 and Figure 4 As shown, the first cleaning member 705 and the second cleaning member 706 are arranged at intervals.

[0039] Specifically, the first cleaning member 705 includes an L-shaped structure composed of a horizontal plate and a vertical plate, and the horizontal plate of the first cleaning member 705 is connected to the outer wall of the rotating member 704 .

[0040] It can be understood that the contact area between the first cleaning member 705 and the residue is small, and the L-shaped structure can better break up the residue. By arranging the first cleaning member 705 and the second cleaning member 706 at intervals, the first cleaning member 705 and the second cleaning member 706 can respectively achieve the functions of breaking up and sweeping up the residue.

[0041] Optionally, see Figure 3 and Figure 4As shown, at least one connecting rod is provided between the vertical plate of the first cleaning member 705 and the outer wall of the rotating member 704 .

[0042] It is understandable that when the rotating member 704 rotates rapidly, in order to enhance the stability of the first cleaning member 705, the connecting rod acts as a reinforcing rib to reduce the impact of centrifugal force and residues on the first cleaning member 705.

[0043] Preferably, please refer to Figure 3 and 4 As shown, the second cleaning member 706 includes a cleaning base plate 7061 and a cleaning side edge 7062 vertically arranged on the cleaning base plate 7061, the cleaning base plate 7061 is connected to the outer wall of the rotating member 704, the first end of the cleaning side edge 7062 is connected to the rotating member 704, and the second end of the cleaning side edge 7062 has a gap with the rotating member 704.

[0044] It can be understood that the cleaning side edge 7062 and the tangent line of the outer wall of the rotating member 704 are inclined at a certain angle, so that the contact area with the residue is increased through the cleaning side edge 7062, and more residues are quickly swept out.

[0045] Preferably, the bottom edge of the first end of the cleaning side edge 7062 is combined with the cleaning bottom plate 7061 and the rotating member 704 to form a material through hole.

[0046] It can be understood that the bottom edge of the first end of the cleaning side 7062, the cleaning bottom plate 7061 and the rotating member 704 together form a material through hole, which prevents residues from accumulating at the angle between the cleaning side 7602 and the rotating member 704.

[0047] Preferably, please refer to Figure 1 and 2 As shown, the discharge port of the residue collection chamber 6 includes a first discharge port 702 and a second discharge port 703 , and both the first discharge port 702 and the second discharge port 703 are connected to the air extraction device 5 .

[0048] It is understandable that the cleaning device 7 is used to remove the residues, and the double discharge ports are connected to the double suction device 5, so that the efficiency of bran discharge can be effectively improved.

[0049] Preferably, please refer to Figure 1 As shown, the rotating member 704 includes a rotating body of a cylindrical structure, a mounting cylinder is arranged at the center line of the rotating body, the mounting cylinder is used to cooperate with the main shaft 4 of the driving mechanism, a hollow groove is opened in the rotating body, and reinforcing ribs are arranged between the side wall of the hollow groove and the mounting cylinder.

[0050] It is understood that the "rotating member 704" herein refers to the rotating structure connected to the main shaft 4. In some embodiments, the rotating member 704 is a cylindrical structure or a disc-shaped structure, and the rotating member 704 is driven to rotate by the driving mechanism. Specifically, the mounting cylinder of the rotating body cooperates with the main shaft 4 of the driving mechanism, and the hollow groove can greatly reduce the overall weight of the rotating member 704, reduce the driving energy consumption, and improve the operating stability of the rotating member 704.

[0051] According to another aspect of the utility model, a rice milling and polishing device is also provided, which comprises the above-mentioned bran discharge system.

[0052] The rice milling and polishing equipment of the utility model also has the above-mentioned beneficial effects.

[0053] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0054] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. The above is only the preferred implementation method of the utility model. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of the utility model, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without improvement, should be regarded as the protection of the utility model.
