Description

Technical Field

[0001] This application relates to the technical field of rice processing, and in particular to a polishing apparatus for rice processing. Background Technology

[0002] In rice processing, polishing is a crucial step in improving the appearance and storage performance of rice. The main purpose of polishing is to remove bran and impurities from the surface of the rice grains through mechanical friction, while simultaneously forming a smooth, glossy film on the surface, thus improving its commercial value.

[0003] According to announcement number CN217989394U, this utility model relates to the field of rice processing technology and discloses a polishing device for rice processing, including a box body. Handles are fixedly connected to the top of the left and right sides of the box body. A feed inlet is provided on the upper surface of the box body. First sliding grooves are fixedly connected to the front and rear sides of the upper surface of the box body. A feed baffle is slidably connected to the inner side of the first sliding groove. A disc is movably connected to the inner wall of the left side of the box body. This polishing device for rice processing, by setting a screen and using a motor to drive the disc to rotate, stirs the rice in the box with polishing rollers. This allows the device to separate broken rice and dust generated during polishing, thus solving the problem that current rice processing polishing devices on the market are unable to separate broken rice, dust, and other impurities generated during polishing, thereby affecting the quality of the processed rice.

[0004] The above-mentioned device polishes rice mainly by using a motor to drive a polishing roller to rub the rice in the mixing tank. However, the polishing structure is simple, and the polishing effect on rice needs to be improved. Utility Model Content

[0005] In order to solve the problems mentioned in the background art, this application provides a polishing apparatus for rice processing.

[0006] The polishing device for rice processing provided in this application adopts the following technical solution:

A screen is inclinedly arranged inside the processing chamber. Baffles are installed on both sides of the inner wall of the processing chamber, with the lower surfaces of the baffles abutting the top of the screen. Multiple sets of kneading mechanisms are fixedly installed at equal intervals between the sides of the baffles. Each kneading mechanism includes a fixed plate and a guide rod fixedly installed between the sides of the two baffles. A rectangular sleeve is sleeved on the outside of the guide rod. A support plate is fixedly installed on the side of the rectangular sleeve. A rubbing board is elastically connected to the side of the support plate. Protrusions are fixedly connected to the corners on the same side of the multiple rectangular sleeves. A horizontal plate is installed between the multiple protrusions. Cylinders are installed on both sides of one side of the baffle, with the extension and retraction ends of the cylinders fixed to the side of the horizontal plate.

[0008] Preferably, springs are installed at all four corners between the support plate and the side of the washboard, and a limiting rod passes through the support plate and the spring, with one end of the limiting rod fixed to the side of the washboard.

[0009] Preferably, rubber sleeves are installed between the four corners of the washboard and the support plate, and each rubber sleeve covers the corresponding spring.

[0010] Preferably, the polishing mechanism includes turntables rotatably mounted on both sides of the inner wall of the processing cavity, a plurality of polishing rollers are circumferentially arranged between the two sides of the turntables, a drive motor is mounted on the side of the processing cavity, and the output end of the drive motor is fixed to the center of the turntable on the same side.

[0011] Preferably, the polishing mechanism includes turntables rotatably mounted on both sides of the inner wall of the processing cavity, a plurality of polishing rollers are circumferentially arranged between the two sides of the turntables, a drive motor is mounted on the side of the processing cavity, and the output end of the drive motor is fixed to the center of the turntable on the same side.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] refer to Figures 1-5 As shown, this application discloses a polishing device for rice processing, including a processing chamber 1 and a polishing mechanism installed inside the processing chamber 1. Rice to be polished is added into the processing chamber 1 through the feeding port at the top of the processing chamber 1. The polishing mechanism is used to polish the rice. A screen 6 is inclinedly arranged inside the processing chamber 1. Baffles 5 are installed on both sides of the inner wall of the processing chamber 1, and the lower surface of the baffles 5 is attached to the upper part of the screen 6, so that the rice can be polished in a concentrated area between the two baffles 5.

[0023] Multiple kneading mechanisms are fixedly installed at equal intervals between the sides of the two side baffles 5. Each kneading mechanism includes a fixed plate 10 and a guide rod 15 fixedly installed between the sides of the two side baffles 5. A rectangular sleeve 17 is sleeved on the outside of the guide rod 15. A support plate 18 is fixedly installed on the side of the rectangular sleeve 17. A rubbing board 16 is elastically connected to the side of the support plate 18. Protrusions 14 are fixedly connected to the corners of the multiple rectangular sleeves 17 on the same side. A horizontal plate 11 is installed between the multiple protrusions 14. Cylinders 12 are installed on both sides of one side baffle 5. The cylinder 12 is fixed to the side of the horizontal plate 11 by extending and retracting. The cylinder 12 drives the horizontal plate 11 to move back and forth laterally. Then, the moving horizontal plate 11 drives multiple protrusions 14 to move synchronously, so that multiple rectangular sleeves 17 can slide outside the guide rod 15. Thus, the support plate 18 can drive the rubbing board 16 to move back and forth on the side of the fixed plate 10. In this way, the rice in the gap between the fixed plate 10 and the rubbing board 16 can be continuously elastically rubbed, increasing the polishing structure of the device and further improving the polishing effect on the rice.

[0024] refer to Figure 4 and Figure 5As shown, springs 20 are installed at the four corners between the support plate 18 and the side of the rubbing board 16. Limiting rods 19 pass through the support plate 18 and the springs 20, and one end of the limiting rods 19 is fixed to the side of the rubbing board 16, so that the rubbing board 16 can move elastically along the guide of the multiple limiting rods 19, avoiding excessive force applied to the rice during rubbing and causing damage to the rice.

[0025] refer to Figure 5 As shown, rubber sleeves 13 are installed between the four corners of the washboard 16 and the support plate 18, and each rubber sleeve 13 covers the outside of the corresponding spring 20 to prevent rice from getting stuck in the gaps of the spring 20 and affecting the normal elastic movement of the washboard 16.

[0026] refer to Figure 1 and Figure 2 As shown, the polishing mechanism includes a turntable 7 rotatably mounted on both sides of the inner wall of the processing cavity 1. Multiple polishing rollers 8 are arranged circumferentially between the sides of the two turntables 7. A drive motor 2 is mounted on the side of the processing cavity 1, and the output end of the drive motor 2 is fixed to the center of the turntable 7 on the same side.

[0027] The output of the drive motor 2 can drive the turntable 7 to rotate, so that multiple polishing rollers 8 can rotate synchronously to stir and rub the rice, thereby polishing the rice.

[0028] refer to Figure 1 and Figure 2 As shown, a door 3 is provided on one side of the processing chamber 1. A guide plate 4 is installed on the side of the processing chamber 1 below the door 3. The door 3 allows for easy opening and closing of the side opening of the processing chamber 1, so that the polished rice can be guided to the collection point with the help of the guide plate 4.

[0029] refer to Figure 2 As shown, a lower inclined plate 9 is installed at an angle below the screen 6 inside the processing chamber 1 to facilitate the discharge of debris falling from below the screen 6 to an opening on one side of the processing chamber 1.

[0030] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] The implementation principle of a polishing device for rice processing according to an embodiment of this application is as follows:

[0033] During processing, the rice to be polished is added into the processing chamber 1 through the feeding port at the top of the processing chamber 1. Then, the drive motor 2 and cylinder 12 are started. The output end of the drive motor 2 can drive the turntable 7 to rotate, so that multiple polishing rollers 8 rotate synchronously to stir and rub the rice, thereby polishing the rice.

[0034] Simultaneously activated cylinder 12 drives horizontal plate 11 to move back and forth laterally. Then, the moving horizontal plate 11 drives multiple protrusions 14 to move synchronously, allowing multiple rectangular sleeves 17 to slide outside the guide rod 15. As a result, support plate 18 can drive rubbing plate 16 to move back and forth on the side of fixed plate 10, thereby continuously elastically rubbing the rice in the gap between fixed plate 10 and rubbing plate 16, increasing the polishing structure of the device and further improving the polishing effect on the rice.
