Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, specifically to a rice milling device for rice processing. Background Technology

[0002] A rice milling machine is a process for removing the husks and whitening brown rice. The rice milling machine mainly uses the collision and friction between rice grains and between rice grains and rice sieves to open and whiten the rice. The air spray system then separates the rice bran from the rice grains and discharges it through the sieve holes.

[0003] A search revealed a utility model patent with Chinese patent publication number CN220143465U, which discloses a rice milling device for reducing broken rice. The device includes a milling cylinder, a load-bearing base at the bottom of the milling cylinder, a feeding pipe at the top of the load-bearing base, a servo motor on one side of the milling cylinder, a rice collection box on one side of the load-bearing base, a bran discharge box on one side of the load-bearing base, and a discharge pipe on one side of the bran discharge box. This utility model utilizes a rice collection box, a bran discharge box, a discharge pipe, a fan cylinder, a filter plate, fan blades, and a drive motor. The device uses the drive motor to rotate the fan blades for air separation. Because the outer layer of rice is lighter than the grains, the outer layer is blown into the bran discharge box during the rice's fall after milling. This screening method is highly effective and increases the device's working efficiency.

[0004] However, this method has certain drawbacks. During the air separation process, due to the gravity of the rice grains as they fall, a large number of rice grains will press down on the husk and accumulate, resulting in insufficient separation between the husk and the rice grains. This requires further separation by workers, increasing the workload of manual separation and thus reducing the overall efficiency of rice processing. Utility Model Content

[0005] The purpose of this invention is to provide a rice milling device for rice processing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rice milling device for rice processing, comprising: a base frame, a feeding frame fixedly installed on the top of the base frame, and a frame door provided on the base frame; a rice milling cylinder, fixedly installed on the top of the feeding frame, a closing plate provided at one end of the rice milling cylinder, an opening at the bottom of the rice milling cylinder, a screening plate detachably installed on the feeding frame, and located directly below the opening of the rice milling cylinder; a rice milling roller, rotatably installed on one side of the inner wall of the rice milling cylinder, an mounting plate slidably installed between the two sides of the inner wall of the base frame, and a collection frame detachably installed on the top of the mounting plate; a fan, fixedly inserted into one side of the base frame, a discharge pipe installed on the other side of the base frame, and a moving component installed on the base frame for driving the mounting plate to move up and down.

[0007] As a further preferred embodiment of this technical solution, a drive motor is installed at the bottom of one side of the rice milling cylinder, and the output end of the drive motor is fixedly connected to one end of the rice milling roller.

[0008] As a further preferred embodiment of this technical solution, a magnet is fixedly installed on the top of the mounting plate, the collection frame is made of iron, and the magnet is magnetically connected to the collection frame.

[0009] As a further preferred embodiment of this technical solution, the moving component includes a rotating rod rotatably mounted between the two sides of the inner wall of the bottom frame. Multiple circular plates are fixedly sleeved on the outer periphery of the rotating rod, and the multiple circular plates are offset from the center of the rotating rod. A linkage component is installed between one end of the rotating rod and one end of the rice milling roller.

[0010] As a further preferred embodiment of this technical solution, the linkage component includes a first pulley fixedly installed at one end of the rotating rod, and a second pulley fixedly installed at one end of the rice milling roller, wherein the first pulley and the second pulley are connected by belt drive.

[0011] As a further preferred embodiment of this technical solution, the screening plate is slidably inserted into the feed frame, and a limit plate is rotatably mounted on the feed frame via a damping shaft.

[0014] (1) This utility model uses a moving component to quickly move the collection frame upward. By utilizing the principle of inertia, the rice grains and the pressed skin are lifted upward. Then, with the help of wind, the skin and rice grains are separated. After multiple operations, the rice grains are discharged through the discharge pipe, which effectively separates the rice grains from the skin. This avoids the problem that a large number of rice grains will press down on the skin and accumulate when falling, resulting in insufficient separation between the skin and rice grains, and subsequent separation by workers. This reduces the labor intensity of workers and improves the overall work efficiency of rice processing.

[0015] (2) The present invention has a detachable screening plate, which is convenient to replace. Screening plates with different aperture sizes are convenient for screening different types of rice, thus improving the adaptability of the device. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 1-4 As shown in this embodiment, a rice milling device for rice processing includes: a bottom frame 1, a feeding frame 2 fixedly installed on the top of the bottom frame 1, and a frame door provided on the bottom frame 1;

[0023] The rice milling cylinder 3 is fixedly installed on the top of the feeding frame 2. One end of the rice milling cylinder 3 is provided with a closed plate, and the bottom of the rice milling cylinder 3 has an opening. A screening plate 4 is detachably installed on the feeding frame 2 and is located directly below the opening of the rice milling cylinder 3.

[0024] Rice milling roller 31 is rotatably mounted on one side of the inner wall of the rice milling cylinder 3. An mounting plate 5 is slidably mounted between the two sides of the inner wall of the bottom frame 1. A collection frame 6 is detachably mounted on the top of the mounting plate 5.

[0025] A blower 7 is fixedly inserted into one side of the base frame 1. A discharge pipe 8 is installed on the other side of the base frame 1. A moving assembly 9 for driving the mounting plate 5 to move up and down is installed on the base frame 1. A drive motor 10 is installed at the bottom of one side of the rice milling cylinder 3. The output end of the drive motor 10 is fixedly connected to one end of the rice milling roller 31.

[0026] The user places rice grains inside the rice milling cylinder 3 by opening the closed plate on the side of the rice milling cylinder 3, and starts the drive motor 10 and the fan 7. When the drive motor 10 starts, it drives the rice milling roller 31 to rotate and crush and remove the husk from the rice grains. After the rice milling operation is completed, the rice grains and rice husks will pass through the screening plate 4 and enter the bottom frame 1. When the rice grains and rice husks enter the bottom frame 1, because the rice husks are lighter and the rice grains are heavier, the rice husks will be blown into the discharge pipe 8 by the wind and discharged from the discharge pipe 8, while the rice grains will fall into the collection frame 6. When the collection frame 6 is filled with a certain amount of milled rice grains, the moving component 9 quickly moves the collection frame 6 upward. Using the principle of inertia, the rice grains and the pressed husks are lifted upward, and then the husks and rice grains are separated by the wind and discharged through the discharge pipe 8, thus achieving effective separation of rice grains and husks.

[0027] like Figure 3 As shown, a magnet 11 is fixedly installed on the top of the mounting plate 5, the collection frame 6 is made of iron, and the magnet 11 is magnetically connected to the collection frame 6.

[0028] When you need to remove the rice grains, simply open the frame door on the bottom frame 1, forcefully pull the collection frame 6 out of the bottom frame 1, and then process the rice grains inside the collection frame 6.

[0029] like Figure 2 As shown, the moving component 9 includes a rotating rod 91 rotatably mounted between the two sides of the inner wall of the base frame 1. Multiple circular plates 92 are fixedly sleeved on the outer periphery of the rotating rod 91, with the circular plates 92 offset from the center of the rotating rod 91. A linkage component 93 is installed between one end of the rotating rod 91 and one end of the rice milling roller 31. The linkage component 93 includes a first pulley 931 fixedly mounted on one end of the rotating rod 91, and a second pulley 932 fixedly mounted on one end of the rice milling roller 31. The first pulley 931 and the second pulley 932 are connected by a belt drive.

[0030] When the drive motor 10 drives the rice milling roller 31 to rotate, the first belt pulley 931 and the second belt pulley 932 drive the rotating rod 91 to rotate synchronously, thereby driving the circular plate 92 to rotate, which in turn causes the mounting plate 5 to bounce up, and at the same time drives the collection frame 6 to move, thereby causing the rice grains and the pressed skin to rise.

[0031] like Figure 1 As shown, the screening plate 4 is slidably inserted into the feed frame 2, and the feed frame 2 is rotatably mounted with a limit plate 12 via a damping shaft.

[0032] During rice milling, the screening plate 4 cannot be changed according to the size of the rice variety, and can only be used for one type of rice, which has certain limitations. By rotating the limiting plate 12 to move it away from the front of the screening plate 4, it can be directly pulled out and replaced. Screening plates 4 with different aperture sizes can be used to screen different types of rice, which improves the adaptability of this device.

[0033] like Figure 2 As shown, a discharge frame 13 is fixedly inserted on one side of the bottom frame 1. The discharge frame 13 has an inclined surface, and the discharge pipe 8 is fixedly inserted on the discharge frame 13.

[0034] The discharge frame 13 is designed to facilitate the concentrated entry of the surface material into the discharge pipe 8, making it less likely to remain in the bottom frame 1.

[0035] This utility model provides a rice milling device for rice processing, the specific working principle of which is as follows:

[0036] The user places rice grains inside the rice milling cylinder 3 by opening the closed plate on the side of the rice milling cylinder 3, and starts the drive motor 10 and the fan 7. When the drive motor 10 starts, it drives the rice milling roller 31 to rotate and crush and remove the husk from the rice grains. After the rice milling operation is completed, the rice grains, along with the rice bran, will pass through the screening plate 4 and enter the bottom frame 1. When the rice grains and rice bran enter the bottom frame 1, because the rice bran is lighter and the rice grains are heavier, the rice bran will be blown into the discharge pipe 8 by the wind and discharged from the discharge pipe 8, while the rice grains will fall into the collection frame 6. When the collection frame 6 is filled with a certain amount of milled rice grains, the moving component 9 quickly moves the collection frame 6 upward. Using the principle of inertia, the rice grains and the pressed husk are lifted upward, and then the husk and rice grains are separated by the wind. After multiple operations, the rice grains are discharged through the discharge pipe 8, achieving effective separation of rice grains and husk.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
