Description

Technical Field

[0001] The invention relates to the field of rice processing, and in particular to a rice processing system and method. Background Art

[0002] Rice processing is a complex and delicate process involving multiple links, aimed at converting rice into high-quality rice products. In the early stages of processing, it is generally divided into processes such as husking, destoning, and dust removal to separate the rice husk and rice, thereby obtaining brown rice for subsequent fine processing. The early brown rice preparation process directly affects the subsequent rice processing quality.

[0003] The Chinese invention patent application with the publication number CN110302859A, a rice processing device and a rice processing process, belongs to the field of rice processing. The technical solution includes a stone remover, a lower hopper, a limit rod driven by a motor, a limit block on the main conveyor belt, a secondary conveyor belt with a buffer spring, and a tertiary conveyor belt. The invention achieves the effect of shortening the rice processing process, reducing the floor space of the rice processing equipment, and enabling the rice bags to be transported stably, and is applied to rice processing.

[0004] The existing rice needs to go through multiple processes during the processing. After the rice is taken out from the barn in the early stage, the amount of rice entering the processing process is controlled by a weight loss flow control scale. However, since the rice is piled up and stored in the barn, it is easy to clump inside, which is easy to affect the subsequent processing steps. In addition, the rice is generally screened in the first step after transportation to screen out impurities such as stones inside. The existing screening method generally adopts vibration screening, but during the screening process, some smaller rice will be screened out along with stones and impurities, resulting in loss and waste. In addition, when the rice is transported to the surface of the vibrating screen, it generally forms an accumulation, which needs to be manually flattened. In addition, during the vibration process, when the accumulation thickness of the rice is high, the vibration cannot guarantee that all the rice is effectively screened, which ultimately affects the processing quality of the rice.

[0039] The breaking component 11 is arranged in the feeding pipe 101 and is used to break up the rice to avoid agglomeration;

[0040] The screening component 20 is arranged in the vibrating cleaning screen 002 and is used to screen the rice to remove internal impurities;

[0041] The combing assembly 21 is arranged in the vibrating cleaning screen 002 and is used for combing and leveling the rice in the screening screen.

[0042] Furthermore, in the above structure, the breaking up component 11 includes a fixed frame 1101, which is symmetrically installed on the inner wall of the feed pipe 101, and a rotating shaft 1102 is rotatably connected between the two groups of fixed frames 1101.

[0043] The connecting frame 1104 can enable the rotating shaft 1102 to drive multiple groups of auxiliary stirring shafts 1105 to rotate.

[0044] Furthermore, in the above structure, fan blades 1106 are fixedly connected above the rotating shaft 1102, a sealing cylinder 1107 is installed above a set of fixing frames 1101, and the fan blades 1106 are arranged inside the sealing cylinder 1107, an air intake pipe 1108 is connected through one side of the sealing cylinder 1107, and the air intake pipe 1108 is connected to an external air pump pipeline.

[0045] The gas is transported to the sealing tube 1107 through the air inlet pipe 1108. At this time, the fan blades 1106 are driven by the gas, thereby causing the rotating shaft 1102 to rotate.

[0047] The air in the sealing cylinder 1107 can be transported to each group of through holes 1110 through the threaded hole 1109 to blow the rice in the feeding pipe 101 to avoid the rice being blocked in the feeding pipe 101. The cooperation of the gear 1112 and the gear ring 1113 can make the stirring auxiliary shaft 1105 rotate as a whole and at the same time rotate on its own, so as to break up the agglomerated rice.

[0048] Furthermore, in the above structure, the screening assembly 20 includes a support frame 2001, which is installed below the material distribution box 201, and sliders 2002 are installed at the four corners of the support frame 2001.

[0049] Through the cooperation of the slide groove 2004 and the slider 2002, the screen frame 2003 can be limited and moved within the support frame 2001.

[0050] Furthermore, in the above structure, a sieve hole 2005 is opened in the sieve frame 2003, and the apertures of the sieve holes 2005 are opened in the sieve frame 2003 in sequence from large to small, and one side of the larger sieve hole 2005 of the sieve frame 2003 is arranged below the discharge port of the distribution box 201, and a connecting rod 2006 is rotatably connected to one side below the sieve frame 2003, and a sliding cavity 2007 is opened in the connecting rod 2006, and a limiting rod 2008 is connected through the sliding cavity 2007, and the limiting rod 2008 is fixedly connected to the inside of the support frame 2001.

[0051] By arranging the sieve holes 2005 from large to small, the stones in the rice can be screened out, and the subsequent small sieve holes 2005 can screen out the dust. Due to the cooperation of the limit rod 2008 and the sliding cavity 2007, the connecting rod 2006 can be driven to rotate when the sieve frame 2003 moves.

[0052] Furthermore, in the above structure, a screen frame 2009 is rotatably connected below the connecting rod 2006, and the connection method of the screen frame 2009 and the support frame 2001 is the same as the connection method of the screen frame 1 2003, and the inclination direction of the screen frame 2009 is opposite to that of the screen frame 1 2003, and the side of the screen frame 2009 away from the connecting rod 2006 is rotatably connected to the rocker 2010, a motor 2011 is installed on one side of the support frame 2001, a turntable 2012 is installed on the output end of the motor 2011, and one side of the turntable 2012 is rotatably connected to the rocker 2010.

[0053] The motor 2011 drives the turntable 2012 to rotate, so that the rocker 2010 drives the screen frame 2009 to slide. At this time, the screen frame 2009 can drive the screen frame 1 2003 to move through the connecting rod 2006, and because the screen frame 2009 and the screen frame 1 2003 are arranged in opposite directions, the screen frame 2009 can screen out the missed rice.

[0054] Furthermore, in the above structure, the combing assembly 21 includes a protective frame 2101, which is installed in the support frame 2001, and the protective frame 2101 covers the screen frame 1 2003 and the screen frame 2009. The inner wall of the protective frame 2101 is symmetrically rotatably connected with a screw rod 2102, one side of the screw rod 2102 is connected to the output end of a servo motor 2110, and the servo motor 2110 is fixedly connected to the inner wall of the protective frame 2101, an internal threaded tube 2103 is threaded on the screw rod 2102, and a slide rod 2104 is fixedly connected below the internal threaded tube 2103, and a limiting ring 2105 is fixedly sleeved on the slide rod 2104.

[0055] The servo motor 2110 can drive the screw rod 2102 to rotate, so that the screw rod 2102 drives the internal threaded tube 2103 to move, and the internal threaded tube 2103 drives the sliding rod 2104 to slide back and forth along both sides of the screen frame 1 2003 and the screen frame 2 2009.

[0056] Furthermore, in the above structure, a sleeve 2106 is slidably connected to the slide rod 2104, and a spring 2107 is fitted between the sleeve 2106 and the limiting ring 2105. This structure is also provided on one side of the screen frame 2009. A roller 2108 is rotatably connected to one side of the limiting ring 2105. The roller 2108 fits the edge of the screen frame 1 2003. A combing rod 2109 is installed between the two groups of rollers 2108, and the combing rod 2109 is provided inside the screen frame 1 2003.

[0057] By moving the slide bar 2104, the roller 2108 can be moved along the edges on both sides of the screen frame 1 2003 and the screen frame 2 2009, and due to the action of the spring 2107, the roller 2108 can always fit with the edges on both sides of the screen frame 1 2003 and the screen frame 2 2009, and the movement of the roller 2108 can drive the combing rod 2109 to rotate, thereby combing the rice inside the screen frame 1 2003 and the screen frame 2 2009.

[0058] A rice processing method comprises the above rice processing system, wherein the processing steps are as follows:

[0059] S1: The rice is conveyed to the weight-loss flow control scale 001 through the feed hopper 102 to control the weight. At this time, the gas is conveyed to the sealing cylinder 1107 through the air pump. At this time, the gas will blow the fan blade 1106 to rotate the stirring screw plate 1103, stirring the agglomerated rice to break it up;

[0060] S2: At this time, the connecting pipe 103 can transport the rice to the inside of the feed hopper 102 above the vibrating cleaning screen 002, so that the rice falls onto the screen frame 1 2003, and the motor 211 drives the screen frame 2 2009 and the screen frame 1 2003 to shake, so that the rice is screened;

[0061] S3: When the rice is being screened, the screw 2102 and the internal threaded tube 2103 cooperate to make the slide bar 2104 drive the roller 2108 to slide along the edges of the screen frame 2 2009 and the screen frame 1 2003, so that the combing rod 2109 moves and rotates, turning and combing the rice, thereby improving the screening effect.

[0062] like Figure 1-9As shown, the rice is transported to the feed pipe 101 through the feed hopper 102, and the gas will enter the sealing cylinder 1107 through the air inlet pipe 1108. At this time, the gas will blow the fan blade 1106, so that the rotating shaft 1102 drives the stirring screw plate 1103 to rotate, and the rotating shaft 1102 drives the multiple groups of stirring auxiliary shafts 1105 to rotate as a whole through the connecting frame 1104, so that the gear 1112 moves along the gear ring 1113, so that the stirring auxiliary shaft 1105 rotates, so that the rice passing through the inside of the feed pipe 101 is scattered to avoid the rice from clumping. At this time, after the rice passes through the weightless flow control scale 001, it will enter the distribution box 201 through the connecting pipe 103. The rice finally falls onto the screen frame 1 2003, and the motor 2011 is started at this time. The motor 2011 drives the screen frame 2009 to reciprocate through the rocker 2010 and the turntable 2012, and drives the upper screen frame 1 2003 to shake through the connecting rod 2006. At the same time, the servo motor 2110 drives the screw 2102 to rotate, so that the internal threaded tube 2103 drives the sliding rod 2104 to move, so that the roller 2108 moves along the edge of the screen frame 1 2003 and the screen frame 2 2009, and drives the combing rod 2109 to rotate, turning the rice, so that the rice can be graded and screened to remove the internal stones, and the combing rod 2109 can improve the screening effect.

[0063] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

A combing rod (2109) is installed between the two groups of rollers (2108), and the combing rod (2109) is provided inside the first screen frame (2003).

10. A rice processing method, comprising a rice processing system according to any one of claims 1 to 9, characterized in that: The processing steps are as follows: S1: The rice is conveyed to the weight-loss flow control scale (001) through the feed hopper (102) to control the weight. At this time, the gas is conveyed to the sealing cylinder (1107) through the air pump. At this time, the gas blows the fan blade (1106) to rotate the stirring screw plate (1103), stirring the agglomerated rice to break it up; S2: At this time, the connecting pipe (103) can transport the rice to the inside of the feed hopper (102) above the vibrating cleaning screen (002), so that the rice falls onto the screen frame 1 (2003), and the motor (211) drives the screen frame 2 (2009) and the screen frame 1 (2003) to shake, so that the rice is screened; S3: When the rice is being screened, the screw (2102) and the internally threaded cylinder (2103) cooperate to cause the sliding rod (2104) to drive the roller (2108) to slide along the edges of the second screen frame (2009) and the first screen frame (2003), thereby causing the combing rod (2109) to move and rotate, thereby turning and combing the rice and improving the screening effect.
