In China, glutinous rice flour is widely used to make various traditional snacks and festival foods, such as tangyuan (sweet rice balls), nian gao (New Year cake), glutinous rice balls, and qingtuan (green rice dumplings). In Southeast Asia, glutinous rice flour is also commonly used to make various pastries and desserts. With the development of globalization and people's pursuit of food culture, the market demand for glutinous rice flour continues to grow, and its application scope is gradually expanding into the international food market.

[0003] When using a glutinous rice flour screening device, traditional screening devices often have glutinous rice flour deposited inside. Once deposited, it is not easy to collect quickly, which can easily cause blockage of the collection port, thus preventing normal screening and reducing the efficiency of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a glutinous rice flour screening device to solve the problem mentioned in the background art that the glutinous rice flour deposited inside the traditional screening device is not easy to collect quickly after deposition, which easily leads to blockage of the collection port of the device, thus preventing normal screening and reducing the working efficiency of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a glutinous rice flour screening device, comprising a fixed base, wherein multiple vibration springs are equidistantly welded to the top of the fixed base near the edge along the circumferential direction, a first screening disc is fixedly welded between the top ends of the multiple vibration springs, a first collection port is provided on one outer surface of the first screening disc, a second screening disc is installed on the top of the first screening disc, a second collection port is provided on one outer surface of the second screening disc, an inlet is provided at the top center of the second collection port, and a filter screen is fixedly provided on the inner wall of the second screening disc near the bottom edge.

[0006] In a preferred embodiment, a motor is fixedly installed at the top center of the fixed base, and a rotating rod is fixedly welded to the motor via an output shaft, and the rotating rod is movably connected to the first screening disc.

[0007] In a preferred embodiment, a first transmission block is fixedly provided on the outer surface of the rotating rod near the bottom edge, and ball bearings are rolled on the top of the first transmission block near both sides.

[0008] In a preferred embodiment, four transmission protrusions are equidistantly arranged at the bottom of the first screening disc along the circumferential direction, and the transmission protrusions are engaged with the balls.

[0009] In a preferred embodiment, a scraper is slidably provided on the outer surface of the rotating rod near the top edge, and a fixing short rod is fixedly provided on the top of the scraper near both sides.

[0010] In a preferred embodiment, a second transmission block is slidably sleeved between the outer surfaces of the two fixed short rods, and the bottom of the second transmission block is fixedly connected to the rotating rod.

[0011] In a preferred embodiment, a return spring is fixedly welded to the bottom edge of the second transmission block near both sides, and the return spring is fixedly welded to the scraper.

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

[0013] This invention firstly involves pouring unscreened glutinous rice flour into the top of a filter screen through the inlet. Starting the motor causes the output shaft to rotate, driving the first transmission block. The interaction between the ball bearings and the transmission protrusion causes the first and second screening discs to vibrate. The vibration of the second screening disc synchronously vibrates the filter screen. The qualified glutinous rice flour is sieved into the first screening disc, while larger particles are discharged through the second collection port. When the qualified glutinous rice flour falls into the first screening disc... Inside the first screening disc, when the rotating rod drives the second transmission block to rotate, the fixed short rod drives the scraper to rotate synchronously. The rotation of the scraper can quickly scrape the glutinous rice flour sieved inside the first screening disc towards the first collection port, thereby achieving a rapid collection effect. With the setting of the return spring, when the first screening disc vibrates up and down, it will drive the scraper to slide up and down. The reverse force of the return spring can make the scraper fit against the inner bottom surface of the first screening disc, improving the scraping effect of the scraper on the glutinous rice flour and improving the working efficiency of the equipment.

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a glutinous rice flour screening device, including a fixed base 1. Multiple vibration springs 2 are equidistantly welded to the top of the fixed base 1 near its edge along the circumferential direction. The vibration springs 2 stabilize the vibration of the first screening disc 3 and the second screening disc 5. A first screening disc 3 is fixedly welded between the tops of the multiple vibration springs 2. A first collection port 4 is provided on one outer surface of the first screening disc 3. The first screening disc 3 and the first collection port 4 allow for the unified collection of the screened glutinous rice flour. A second screening disc 5 is installed on the top of the first screening disc 3. A second collection port 6 is provided on one outer surface of the second screening disc 5. The second collection port 6 allows for the unified collection of larger glutinous rice flour particles. An inlet 7 is provided at the center of the top of the second collection port 6, allowing the glutinous rice flour to be inverted inside the device. A filter screen 8 is fixedly installed on the inner wall of the second screening disc 5 near its bottom edge. When the device vibrates, the filter screen 8 separates the unscreened glutinous rice flour.

[0022] A motor 10 is fixedly installed at the top center of the fixed base 1. When the motor 10 is started, the rotation of the output shaft of the motor 10 can drive the rotating rod 11 to rotate. The rotating rod 11 is fixedly welded to the output shaft of the motor 10, and the rotating rod 11 is movably set with the first screening disc 3. The rotation of the rotating rod 11 can drive the first transmission block 12, the scraper 14 and the second transmission block 16 to rotate synchronously. The first transmission block 12 is fixedly installed on the outer surface of the rotating rod 11 near the bottom edge. The top of the first transmission block 12 is rolled with balls 13 near the two sides. The bottom of the first screening disc 3 is equidistantly arranged with four transmission protrusions 9 along the circumferential direction, and the transmission protrusions 9 are engaged with the balls 13. The rotation of the first transmission block 12 can drive the balls 13 to rotate in a circle. Under the transmission engagement of the balls 13 and the transmission protrusions 9, the first screening disc 3 and the second screening disc 5 can be driven to vibrate.

[0023] A scraper 14 is slidably mounted on the outer surface of the rotating rod 11 near its top edge. A fixed short rod 15 is fixedly mounted on the top of the scraper 14 near both sides. A second transmission block 16 is slidably sleeved between the outer surfaces of the two fixed short rods 15, and the bottom of the second transmission block 16 is fixedly connected to the rotating rod 11. A return spring 17 is fixedly welded to the bottom of the second transmission block 16 near both sides, and the return spring 17 is fixedly welded to the scraper 14. Through the arrangement of the fixed short rods 15 and the second transmission block 16, when the rotating rod 11 drives... When the second transmission block 16 rotates, the scraper 14 can be driven to rotate synchronously through the fixed short rod 15. The rotation of the scraper 14 can quickly scrape the glutinous rice flour sieved inside the first screening disc 3 towards the first collection port 4, thereby achieving a rapid collection effect. With the setting of the reset spring 17, when the first screening disc 3 vibrates up and down, it will drive the scraper 14 to slide up and down. The reverse force of the reset spring 17 can make the scraper 14 fit with the inner bottom surface of the first screening disc 3, improving the scraper 14's scraping effect on the glutinous rice flour.

[0024] Working principle: When the glutinous rice flour screening device is used, the unscreened glutinous rice flour is first poured into the filter screen 8 through the feed port 7. By starting the motor 10, the output shaft of the motor 10 drives the first transmission block 12 to rotate. With the transmission engagement of the ball bearing 13 and the transmission protrusion 9, the first screening disc 3 and the second screening disc 5 vibrate. The vibration of the second screening disc 5 synchronously drives the filter screen 8 to vibrate. The qualified glutinous rice flour is screened through the filter screen 8 and falls into the interior of the first screening disc 3, while larger particles are discharged and collected through the second collection port 6. After falling into the first screening disc 3, the rotation of the rotating rod 11 drives the second transmission block 16 to rotate, which in turn drives the scraper 14 to rotate synchronously through the fixed short rod 15. The rotation of the scraper 14 can quickly scrape the glutinous rice flour sieved inside the first screening disc 3 towards the first collection port 4, thereby achieving a rapid collection effect. With the setting of the return spring 17, when the first screening disc 3 vibrates up and down, it will drive the scraper 14 to slide up and down. The reverse force of the return spring 17 can make the scraper 14 fit with the inner bottom surface of the first screening disc 3, which improves the scraping effect of the scraper 14 on the glutinous rice flour and improves the working efficiency of the equipment.
