Description
Technical Field
[0001] The utility model relates to the technical field of rice processing equipment, in particular to a rice impurity removal device for rice processing. Background Art
[0002] In the process of removing the outer husk and cortex of rice to obtain rice, it will be mixed with various impurities such as sand, gravel, soil and rice straw due to defects in the processing environment and processing equipment. In order to ensure the quality of rice, the rice needs to be removed after husking.
[0003] The utility model patent with patent authorization announcement number CN221753976U discloses a device for removing impurities and stones for rice processing, including: a base plate; a box body, the box body is installed on the base plate, two box doors are provided on the box body, a vibration component for driving the box body to vibrate is installed between the box body and the base plate, a feed frame is fixedly inserted on the top of the box body; the first filter frame is detachably installed on the box body.
[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that when rice is added through the top opening of the feed frame, the rice falls at a fast speed. Therefore, in order to ensure the removal effect of dust and straw, the blowing fan needs to be kept on during the rice adding process. As a result, when the blowing fan blows air on the rice, some dust and straw will enter the air in the working environment through the top opening of the feed frame under the influence of the airflow, and cannot be effectively collected by the collection frame. The actual use effect is not ideal and it is easy to cause pollution to the working environment.
[0005] Therefore, it is necessary to invent a rice processing rice impurity removing device to solve the above problems. Utility Model Content
[0006] The utility model aims to provide a rice impurity removal device for rice processing. The device is provided with a second impurity removal mechanism so that before the rice is added into the shell through the top opening of the feed frame, the suction pump is started. After the suction pump is started, the air inside the sealing cover is sucked through the second negative pressure pipe, so that negative pressure is generated inside the sealing cover. The negative pressure is transmitted to the inside of the hollow frame through the dust filter bag, the internal threaded sleeve, the external threaded sleeve and the first negative pressure pipe, and then transmitted to the entrances of multiple air holes. When the rice passes through the hollow frame, the dust and straw in the rice enter the hollow frame through the air holes under the action of the negative pressure, and then enter the dust filter bag through the first negative pressure pipe, the external threaded sleeve and the internal threaded sleeve in sequence and are collected. After the collection and impurity removal are completed, the sealing door on the left side of the sealing cover is opened, and then the internal threaded sleeve is unscrewed from the outside of the external threaded sleeve, and finally the dust and straw are poured out from the inside of the dust filter bag and processed, so as to solve the problem proposed in the above background technology that when rice is added through the top opening of the feed frame, the rice falls at a fast speed. Therefore, in order to ensure the removal effect of dust and straw, the blowing fan needs to be kept on during the rice adding process. As a result, when the blowing fan blows air to the rice, some dust and straw will enter the air in the working environment through the top opening of the feed frame under the drive of the airflow, and cannot be effectively collected by the collection frame. The actual use effect is not ideal, and it is easy to cause pollution to the working environment.

[0030] For descriptive purposes, this disclosure may use spatially relative terms such as "below," "beneath," "beneath," "below," "above," "upper," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the drawings is turned over, a component described as "below" or "beneath" another component or feature would then be oriented "above" the other component or feature. Thus, the exemplary term "below" can encompass both "above" and "below" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein interpreted accordingly.
[0031] Figure 1 The figure is a schematic diagram of the overall structure of a rice impurity removal device for rice processing according to one embodiment of the present disclosure.
[0032] Figure 2 The figure is a schematic diagram of the overall cross-sectional structure of a rice impurity removal device for rice processing according to one embodiment of the present disclosure.
[0033] Figure 3 1 is a schematic cross-sectional structural diagram of a shell mechanism 2 and a first impurity removal mechanism 3 of a rice impurity removal device for rice processing according to one embodiment of the present disclosure.
[0034] Figure 4 1 is a schematic cross-sectional structural diagram of a second impurity removal mechanism 4 of a rice impurity removal device for rice processing according to an embodiment of the present disclosure.
[0035] like Figures 1-4 As shown, the rice impurity removal device for rice processing disclosed herein may include: a base 1 , a shell mechanism 2 , a first impurity removal mechanism 3 , a second impurity removal mechanism 4 and other components.
[0036] like Figure 3 As shown, in the present disclosure, the shell mechanism 2 includes an outer shell 21, a vibration motor 22 and a feed frame 23, wherein the outer shell 21 is fixedly arranged on the top of the base 1, the vibration motor 22 is fixedly arranged through the middle of the left side of the outer shell 21, and the feed frame 23 is fixedly nested on the top of the outer shell 21.
[0037] Thus, the rice to be cleaned is added into the housing 21 through the top opening of the feed frame 23 for the cleaning operation. In addition, during the rice cleaning process, the vibration motor 22 drives the housing 21 to vibrate, so that the rice and solid impurities in the rice can pass through the first filter plate 31 and the second filter plate 32 to be screened.
[0038] like Figure 3 As shown, in a preferred embodiment, the first impurity removal mechanism 3 includes a first filter plate 31, a second filter plate 32, a supporting plate 33 and a handle 34, wherein the first filter plate 31, the second filter plate 32 and the supporting plate 33 are arranged in sequence from top to bottom and are all slidably penetrated and arranged on the right side of the shell 21 and extend into the interior of the shell 21, and the handle 34 is fixedly arranged on the right side of the first filter plate 31, the second filter plate 32 and the supporting plate 33.
[0039] Therefore, after the impurity removal is completed, large particles of debris are accumulated on the top of the first filter plate 31, rice is accumulated on the top of the second filter plate 32, and small particles of debris are accumulated on the top of the supporting plate 33. After the impurity removal is completed, the handle 34 is pulled, and the handle 34 drives the first filter plate 31, the second filter plate 32 and the supporting plate 33 to move outward. At this time, a large amount of rice accumulated on the top of the second filter plate 32 falls from the top of the second filter plate 32 and is discharged. Then, a small amount of large particles of debris on the top of the first filter plate 31 and a small amount of small particles of debris on the top of the supporting plate 33 are cleaned.
[0040] like Figure 4 As shown in the present disclosure, the second impurity removal mechanism 4 includes a hollow frame 41, an air hole 42, a first negative pressure pipe 43, a sealing cover 44, an externally threaded sleeve 45, an internally threaded sleeve 46, a dust filter bag 47, a second negative pressure pipe 48 and a suction pump 49, wherein the hollow frame 41 is fixedly arranged at the bottom of the feed frame 23, a plurality of air holes 42 are provided, and the plurality of air holes 42 are evenly opened on the inner side of the hollow frame 41, the first negative pressure pipe 43 is fixedly penetrated and arranged on the left side of the hollow frame 41 and extends to the outside of the shell 21, the sealing cover 44 is fixedly sleeved on the outside of the first negative pressure pipe 43 and fixedly arranged on the left side of the outer shell 21, the external threaded sleeve 45 is fixedly sleeved on the outer end of the first negative pressure pipe 43 and is located inside the sealing cover 44, the internal threaded sleeve 46 is threadedly sleeved on the outside of the external threaded sleeve 45, the dust filter bag 47 is fixedly connected to the bottom of the internal threaded sleeve 46, the second negative pressure pipe 48 is fixedly penetrated and arranged on the rear side of the sealing cover 44, and the suction pump 49 is fixedly connected to the end of the second negative pressure pipe 48 and fixedly arranged on the left side of the outer shell 21.
[0041] Thus, before the rice is added into the shell 21 through the top opening of the feed frame 23, the suction pump 49 is started. After the suction pump 49 is started, the air inside the sealing cover 44 is sucked through the second negative pressure pipe 48, so that a negative pressure is generated inside the sealing cover 44. The negative pressure is transmitted to the inside of the hollow frame 41 through the dust filter bag 47, the internally threaded sleeve 46, the externally threaded sleeve 45 and the first negative pressure pipe 43, and then transmitted to the entrance of the multiple air holes 42. When the rice passes through the hollow frame 41 subsequently, the dust and straw in the rice enter the inside of the hollow frame 41 through the air holes 42 under the action of the negative pressure, and then enter the dust filter bag 47 through the first negative pressure pipe 43, the externally threaded sleeve 45 and the internally threaded sleeve 46 in turn and are collected. After the impurity removal is completed, the sealing door on the left side of the sealing cover 44 is opened, and then the internally threaded sleeve 46 is unscrewed from the outside of the externally threaded sleeve 45. Finally, the dust and straw are poured out from the inside of the dust filter bag 47 and disposed of.
