Abstract
Description
Technical Field
[0001] The present application relates to the technical field of screening machines, and in particular to a glutinous rice flour screening device. Background Art
[0002] For the production process of glutinous rice flour, dry grinding is one of the indispensable steps. In this step, a special grinding machine is usually used to dry grind glutinous rice into a fine powder. During the dry grinding process, glutinous rice will be placed in the grinding machine and then ground by mechanical force to finally produce fine and uniform glutinous rice flour. In order to make the taste of glutinous rice flour more delicate and improve its quality, glutinous rice flour often needs to be sieved after grinding to make the particle size of the glutinous rice flour uniform and remove impurities.
[0003] For example, the utility model patent with publication number CN215918142U specifically discloses a rapid impurity removal device for the production and processing of glutinous rice flour. Through the arrangement of a fixed block, a shock-absorbing spring, a telescopic sleeve, an impurity removal groove, a vibration block, a vibration motor, a card slot, a card block and a screening net, when in use, it can cooperate with the screening net to quickly shake the glutinous rice inside to remove impurities. When the glutinous rice enters the impurity removal groove from the feed hopper, it can be quickly impurified and screened into the collection box below.
[0004] In the above patent, the device drives the screening net to vibrate through a vibration motor, so that the glutinous rice is screened and impurities are removed. However, for glutinous rice flour, when the glutinous rice flour falls out of the sieve holes on the screening net, some glutinous rice flour may remain on the screening net due to being relatively moist, which may clog the sieve holes over time and affect subsequent screening work. Therefore, it is necessary to provide a glutinous rice flour screening device with a cleaning device to solve the above problem.
[0005] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.
[0024] like Figure 1-Figure 2 As shown, the present application provides a glutinous rice flour screening device, comprising a bracket 1, the bracket 1 is arranged in a glutinous rice flour processing workshop, and a grinder 2 is fixedly installed on the top of the bracket 1, the grinder 2 is used to dry-grind glutinous rice into glutinous rice flour, the grinder 2 has a feed port 21 and a discharge port 22, wherein the glutinous rice enters the grinder 2 through the feed port 21, and after the glutinous rice is ground by the grinder 2, it is discharged from the discharge port 22;
[0025] At the same time, a screening mechanism 3 is provided on one side of the discharge port 22, and the screening mechanism 3 is used to screen the glutinous rice flour to make the particle size of the glutinous rice flour more uniform, thereby ensuring that the quality and particle size of the glutinous rice flour during the processing process meet the production requirements.
[0026] The screening mechanism 3 includes a receiving plate 31, and a plurality of rotating wheels 32 adapted to the bracket 1 are arranged at the bottom of the receiving plate 31, so that the receiving plate 31 is suitable for moving on the top of the bracket 1 through the rotating wheels 32, and a connecting frame 33 is fixedly installed on the top of the receiving plate 31, and a sieve plate 34 is hinged in the connecting frame 33, and the ground glutinous rice flour is output from the discharge port 22 to the sieve plate 34;
[0027] At the same time, a driving part 4 is arranged on one side of the screening mechanism 3, and the driving part 4 includes a motor 41 arranged at the bottom of the bracket 1, and a first turntable is fixedly installed at the output end of the motor 41. At the same time, a rotating shaft 42 is rotatably connected above the motor 41 on the bracket 1, and the rotating shaft 42 has a second turntable. A belt is arranged between the first turntable and the second turntable, so that the motor 41 is suitable for driving the rotating shaft 42 to rotate;
[0028] At the same time, an eccentric shaft 43 is fixedly installed on the end of the rotating shaft 42 away from the second rotating disk, and a connecting rod 44 is rotatably connected to the eccentric shaft 43. The end of the connecting rod 44 away from the eccentric shaft 43 is fixedly connected to the receiving plate 31, so that when the rotating shaft 42 rotates, the eccentric shaft 43 and the connecting rod 44 cooperate to drive the receiving plate 31 to reciprocate on the bracket 1, and at this time, the glutinous rice flour on the sieve plate 34 will be evenly sieved and fall into the receiving plate 31;
[0029] At the same time, the connecting frame 33 and the receiving plate 31 are respectively provided with a first discharge end 35 and a second discharge end 36 on the end away from the grinder 2.
