Technical Field

[0001] This utility model relates to the technical field of rice polishing machines, specifically a rice polishing device. Background Technology

[0002] A rice polishing machine is a mechanical device used to improve the appearance quality and gloss of rice. It removes bran and tiny impurities from the surface of rice through physical methods, making the rice look whiter and smoother.

[0003] Currently, rice polishing machines are basically composed of four parts: the housing, the agitator, the polishing cylinder, and the dust collector. Although the dust collector can prevent a large amount of rice husk ash from being blown up when the polishing machine is working, the collected rice husk ash needs to be cleaned separately, which increases the difficulty of maintenance. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a rice polishing device to solve the problem mentioned in the background art that the rice polishing machine needs to clean the rice husk ash separately.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rice polishing device, comprising a cylinder, a first support provided on the outer wall of the cylinder, a second motor installed at one end of the first support, one end of the shaft of the second motor connected to the shaft at one end of the cylinder, a sealing door hinged to one side of the cylinder, a lock provided on the sealing door, a partition fixedly connected inside the cylinder, a polishing plate provided on the inner wall of the bottom of the cylinder, a stirrer provided on the polishing plate, an opening provided on the partition, a filter screen provided on the top of the partition, a negative pressure fan provided on the top of the filter screen, and an exhaust port provided on the top of the cylinder.

[0006] Preferably, a sealing plate is rotatably connected to the top side of the partition opening, and the sealing plate is symmetrically distributed about the bisector of the partition opening.

[0011] Preferably, a first motor is installed on the other side of the cylinder, and one end of the first motor shaft is connected to one side of the rotating shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This device can automatically discharge rice husks while automatically discharging the material, thereby avoiding separate operations for discharging the material and discharging the rice husks, and improving work efficiency.

[0014] (2) This device is equipped with a cylinder that automatically adjusts its angle up and down, and the cylinder is divided into two parts by a partition.

[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] Please see Figure 1-4 This utility model provides a technical solution: a rice polishing device, including a cylinder 3, a first support 2 provided on the outer wall of the cylinder 3, a second support 6 fixedly connected to one side of the first support 2, and a hydraulic cylinder 18 installed on the inner wall of the second support 6. The top of the hydraulic cylinder 18 is movably connected to the bottom of the cylinder 3. The hydraulic cylinder 18 is rotatably connected to the cylinder 3, thus cooperating with the rotation of the cylinder 3 during rotation, and also providing support to one side of the cylinder 3, improving the stability of the cylinder 3 during use. A rotating shaft 16 is rotatably connected to the inner wall of the cylinder 3, and a stirrer 12 is fixedly connected to the outer wall of the rotating shaft 16. A first motor 1 is installed on the other side of the cylinder 3. One end of the motor 1 shaft is connected to one side of the rotating shaft 16; this structure allows the rotating shaft 16 to rotate via the first motor 1, thereby causing the stirrer 12 to oscillate left and right, thus agitating the rice and allowing it to repeatedly contact the polishing plate 17 for polishing; the polishing plate 17 can be made of polishing stone; a second motor 15 is installed at one end of the first bracket 2, and one end of the shaft of the second motor 15 is connected to the shaft at one end of the cylinder 3. A sealing door 4 is hinged to one side of the cylinder 3, and a latch 5 is provided on the sealing door 4. The latch 5 includes a pin and a socket bracket. The socket bracket is located on the outer wall of the cylinder 3, and the pin is located on the sealing door 4, thereby sealing the sealing door 4 to the cylinder 3. Internally, a partition 14 is fixedly connected to the cylinder 3. A polishing plate 17 is installed on the inner wall of the bottom of the cylinder 3, and an agitator 12 is installed on the polishing plate 17. An opening is opened on the partition 14, and a sealing plate 13 is rotatably connected to the top side of the opening of the partition 14. The sealing plates 13 are symmetrically distributed about the bisector of the opening of the partition 14. When the negative pressure fan 7 of this structure is working, it can use the suction force of negative pressure to pull the sealing plate 13 upward and rotate it open, thereby ensuring the smooth collection of rice husk ash. A fixing frame 10 and a dust cover 9 are fixedly connected to both sides of the opening of the partition 14. The dust cover 9 is fitted on the outer wall of the fixing frame 10 and is made of rubber. The bottom side of the dust cover 9 is fixedly connected to the top of the sealing plate 13 through the dust cover. 9 can provide dust protection for the fixing frame 10 and the support spring 11, preventing rice husk ash from adhering to the surface of the fixing frame 10 and the support spring 11 and making them difficult to clean; the support spring 11 is fixedly fixed at the bottom of the fixing frame 10 at an angle, and one end of the support spring 11 is fixedly connected to the top of the sealing plate 13; this structure can support the sealing plate 13 to seal the partition 14 through the support spring 11, preventing rice husk ash on the top of the partition 14 from falling into the lower end of the partition 14; a filter screen 8 is provided on the top of the partition 14, and a negative pressure fan 7 is provided on the top of the filter screen 8, and an exhaust port is opened on the top of the cylinder 3; the filter screen 8 can intercept rice husk ash, reducing the phenomenon of rice husk ash adhering to the surface of the negative pressure fan 7.

[0023] Working principle: When using this rice polishing device, first open the sealing door 4 and the latch 5 to add the rice to be polished into the cylinder 3. At this time, the right side of the cylinder 3 is tilted upward. Then, after closing the sealing door 4 and the latch 5, the first motor 1 drives the rotating shaft 16 and the agitator 12 to move the rice to contact the polishing plate 17 for polishing. During the polishing process, the rice husk produced is adsorbed by the negative pressure of the negative pressure fan 7 and passes through the partition 14 to be collected at the top of the partition 14. When the negative pressure fan 7 stops, the negative pressure decreases, and the sealing plate 13 descends under the support of the support spring 11 to seal the top opening of the partition 14. Then, the sealing door 4 and the latch 5 are opened, and the collection frame is used to correspond to the top and bottom discharge areas of the partition 14 respectively. Then, the second motor 15 drives the cylinder 3 to rotate, causing the right side of the cylinder 3 to tilt downward. At the same time, the hydraulic cylinder 18 retracts. When the cylinder 3 tilts, the rice and rice husk inside the cylinder 3 are collected respectively.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
