Description

Technical Field

[0001] The utility model relates to the technical field of grain processing, and more specifically to a grain processing polishing device. Background Art

[0002] Grain processing refers to the business activities of converting raw grains into semi-finished grains or finished grains, or converting semi-finished grains into finished grains. During the rice processing, in order to improve the appearance of the rice, it is necessary to use a polishing device to polish the shelled rice.

[0003] After searching, the existing patent (publication number: CN220027093U) discloses a polishing device for grain processing. During use, rice is added into the polishing box through a feeding pipe, the feeding pipe is sealed, and the first motor is started to drive the threaded rod to rotate. The rotation of the threaded rod drives the threaded block and the rack to move. The movement of the rack drives the first gear and the first rotating shaft to rotate. The rotation of the first rotating shaft drives the polishing box to rotate. The rotation of the polishing box can drive the rice to be fully turned over. At the same time, the third motor is started to drive the second gear to rotate. The rotation of the second gear drives the third gear to rotate. The rotation of the third gear drives the polishing roller to rotate. The rotating polishing roller can fully polish the rice, thereby increasing the polishing efficiency. However, the inventor discovered the following problems in the prior art during the process of realizing the utility model: although the above-mentioned polishing device can ensure that the rice can be polished evenly, when used for rice processing, a staged processing method is adopted, that is, the rice is first added into the polishing box. During the polishing process, the polishing box is in a rotating state. At this time, in order to prevent the rice from leaking out of the discharge pipe, the discharge pipe is closed. After the polishing is completed, the discharge pipe is opened again to pour out the whole rice. Such a processing method has the defects of discontinuous processing and low processing efficiency.

[0004] In view of this, the utility model proposes a grain processing polishing device capable of continuously processing rice. Utility Model Content

[0024] The polishing vibration assembly includes a plurality of polishing rollers 5 rotatably connected to the inside of the polishing box 1, the polishing rollers 5 correspond to the positions of the receiving mesh plate 4, the plurality of polishing rollers 5 are divided into two groups, each group of polishing rollers 5 are connected by a chain transmission, two reduction motors 6 for driving the two groups of polishing rollers 5 to rotate are fixedly installed on the front of the polishing box 1, a shaft rod 7 is rotatably connected to the front of the polishing box 1, the output shaft of the reduction motor 6 on the left side is connected to the shaft rod 7 by a chain transmission, a protective shell is provided on the outside of the chain, a plurality of knocking blocks 8 are welded on the surface of the shaft rod 7 in a circular array at equal intervals, an arc block 9 is fixedly installed on the surface of the receiving mesh plate 4, and the positions of the knocking blocks 8 and the arc block 9 correspond.

[0025] When the utility model is in use, rice is continuously added into the polishing box 1 from the feed hopper 2, and the rice slides down to the right from the surface of the receiving mesh plate 4 in the polishing box 1. During the sliding process, the polishing roller 5 is driven to rotate by the reduction motor 6, so that the effect of polishing the rice can be achieved. At the same time, the striking block 8 is driven to continuously collide with the arc block 9 through the rotation of the shaft rod 7, so that the receiving mesh plate 4 can be vibrated, and the rice is promoted to turn over on the surface of the receiving mesh plate 4, so as to ensure the uniformity of the rice polishing process. When the overall device is in use, the rice can be continuously polished, and the processing effect is high.

[0026] The receiving mesh plate 4 is movably installed on the inner wall of the polishing box 1, and a limiting slide bar 10 is fixedly installed on the inner wall of the polishing box 1.

The receiving mesh plate 4 is slidably connected to the surface of the limiting slide bar 10, and the surface of the limiting slide bar 10 is sleeved with a return spring 11 for supporting the receiving mesh plate 4.

[0027] Since the receiving mesh plate 4 is slidably connected to the surface of the limiting slide rod 10 under the elastic support of the return spring 11, when the knocking block 8 and the arc block 9 collide, the receiving mesh plate 4 can be driven to vibrate strongly, which has a good effect on turning the rice.

[0028] A slag collecting drawer 12 is inserted on the left side of the polishing box 1 . The slag collecting drawer 12 extends into the interior of the polishing chamber, and the upper opening of the slag collecting drawer 12 corresponds to the lower end position of the receiving mesh plate 4 .

[0029] During the polishing process, the receiving mesh plate 4 vibrates, so that the rice bran can pass through the receiving mesh plate 4 and fall into the slag collecting drawer 12, thereby achieving the effect of collecting the rice bran and ensuring the quality of the finished rice product.

[0030] A handle is welded on the left side of the slag collecting drawer 12 , and a magnet 13 is embedded on the left side of the slag collecting drawer 12 . An iron sheet 14 is embedded on the left side of the polishing box 1 , and the magnet 13 and the iron sheet 14 are magnetically attracted to each other.

[0031] By providing the magnet 13 and the iron sheet 14 and utilizing the magnetism between the magnet 13 and the iron sheet 14, the slag collecting drawer 12 can be positioned to avoid the slag collecting drawer 12 being separated due to the vibration of the device.

[0033] A notch 19 is provided on the right side of the dust box 18 corresponding to the air outlet end of the air inlet pipe 16 , and a dust filter 20 is embedded on the left side of the dust box 18 , and the dust filter 20 corresponds to the position of the air inlet end of the exhaust fan 17 .

[0034] By providing the dust box 15 and the dust collecting box 18, during the rice polishing process, the exhaust fan 17 is used to induce air to flow into the dust collecting box 15, so that the dust generated by the rice polishing can be introduced into the dust collecting box 15, and then collected in the dust collecting box 18 under the filtering action of the dust filter 20, thereby ensuring the cleanliness of the processing environment and the quality of the rice.

[0035] It is worth noting that, since the suction force of the exhaust fan 17 acts on the inside of the dust box 15, the negative pressure directly acts on the surface of the dust box 18, and therefore, there is no need to perform additional positioning on the dust box 18.

[0036] An inclined plate 21 is fixedly mounted on the inner left wall of the polishing box 1 , and the inclined plate 21 corresponds to the air inlet end position of the air inlet pipe 16 .

[0037] By providing the inclined plate 21 , the rice bran falling from the receiving mesh plate 4 can be blocked, thereby preventing the rice bran from entering the dust collecting box 15 under the action of the airflow.

[0038] Finally, it should be noted that the drawings of the embodiments disclosed in the present invention only involve structures related to the embodiments disclosed in the present invention, and other structures may refer to the usual design.
