Description

Technical Field

[0001] The utility model relates to the technical field of rice hullers, in particular to a rice huller with a rapid dust removal component. Background Art

[0002] In the existing grain processing industry, rice hullers are one of the indispensable and important equipment. When grinding grains, traditional rice hullers inevitably produce a lot of dust. These dust and other debris not only affect the quality of the processed grains, but also cause pollution to the workshop environment. In order to avoid the above phenomenon, people have developed rice hullers with dust removal functions, such as the "Rice Huller with Automatic Dust Removal Function" with authorization announcement number CN217410862U. It uses a spraying method to achieve dust removal. Although this has a high dust removal effect, the sprayed water mist can easily escape to the grains being processed, resulting in an increase in the moisture content of the grains being processed. After the processing is completed, it needs to be aired again. The operation is somewhat cumbersome and is not conducive to the normal progress of subsequent work. This has affected the quality and efficiency of grain processing to a certain extent.

[0033] In this embodiment, in order to prevent the grains on the sieve plate 3 from falling from the front and rear sides of the sieve plate 3 , baffles are fixedly installed on the front and rear sides of the top of the sieve plate 3 .

[0037] The grain grinding processing part and related circuits and electronic components all use existing technologies, which can be fully implemented by those skilled in the art. Needless to say, the content protected by this application does not involve improvements to software, circuits and methods.

[0038] Working principle:

[0039] When the rice huller with a rapid dust removal component of the present invention starts to work, first the power is turned on and motor 1 32 and motor 2 5 are started, and the grains enter the rice milling processing part 2 in the rice huller shell 1 through the feed hopper 11 for grinding. The ground grains and husk mixture falls on the sieve plate 3. Due to the drive of motor 1 32, the turntable 33 pushes the sieve plate 3 to reciprocate back and forth through the support rod 35, which can control the sieve plate 3 to quickly screen the husks and grains. The separated grains fall into the bottom of the rice huller shell 1 through the sieve holes of the sieve plate 3, and due to the inclined design of the bottom inner wall of the rice huller shell 1, the grains can smoothly slide to the feed port of the discharge pipe 12, and thus be discharged from the rice huller shell 1, while the husks and unshelled grains and other debris remain on the sieve plate 3 and are thrown up during the reciprocating motion of the sieve plate 3. The unshelled grains will move along the sieve plate 3 and be discharged through the discharge port.

[0040] At the same time, under the action of motor 2 5, the rotating shaft 51 and the gear disc 54 are driven to rotate. Due to the meshing relationship between multiple gears 56 and the gear disc 54, multiple rotating pins 55 and fan blades 57 also start to rotate synchronously. The rotating fan blades 57 draw the air in the rice huller shell 1 into the mounting cylinder 4 through the air inlet pipe 13 and then discharge it through the air outlet. In this process, the chaff and other debris on the screen plate 3 and the thrown chaff and other debris can be sucked into the mounting cylinder 4, and are intercepted by the filter plate 41, and then fall into the cloth bag 42 for collection.

[0041] When the motor 2 5 drives the rotating shaft 51 to rotate, the multiple scrapers 52 also rotate accordingly, which can clean the filter plate 41, thereby effectively preventing the filter plate 41 from being blocked by debris such as husks, and ensuring the continuous and efficient operation of the filter plate 41.

[0042] In addition, since baffles are fixedly installed on the front and rear sides of the sieve plate 3, the grains on the sieve plate 3 are effectively prevented from falling from the front and rear sides of the sieve plate 3, thereby improving the efficiency of grain processing, and the setting of the guide rod 31 ensures the stability and guidance of the sieve plate 3 during the reciprocating motion.

[0043] The above is a detailed introduction to the rice huller with a rapid dust removal assembly provided by the present invention. This article uses specific embodiments to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only intended to help understand the method and core concept of the present invention.
