Description

Technical Field

[0001] The invention relates to the technical field of rice processing, in particular to organic rice fine processing and sorting equipment. Background Art

[0002] Organic rice refers to rice produced in accordance with organic agricultural standards during the planting process. These standards usually include not using chemically synthesized pesticides, fertilizers, herbicides, and genetically modified technology. Organic rice finishing and sorting equipment is used to clean, hull, mill, polish, color sort and other processes of rice to produce high-quality rice.

[0003] During rice production and processing, rice grains vary in size, and the shriveled or smaller grains need to be sorted and screened out to ensure the overall quality control requirements of the processed rice grains. However, existing rice processing equipment usually filters out large particles of debris through a sieve plate, so that shriveled or smaller rice grains are still mixed in, resulting in limited sorting capacity. The quality control of the processed rice after sorting still does not meet the actual processing requirements.

[0004] Therefore, the present invention proposes an organic rice fine processing and sorting device to make up for and improve the deficiencies of the prior art. Summary of the invention

[0017] Beneficial effects:

[0018] 1. This device is equipped with a wind sorting mechanism, which uses a fan to blow airflow to the falling rice, so that the shriveled particles in the rice are blown to the air outlet by the airflow, thereby removing the empty shells, broken rice, grass clippings and other light impurities in the rice. At the same time, the use of wind sorting can treat the rice more gently, reducing the increase in broken rice rate caused by rough operation, while improving the sorting efficiency. It can also reduce the loss of rice and improve the overall quality of rice.

[0019] 2. This device is provided with a collection component. When the airflow blows the light impurities to the air outlet, the airflow pushes the impurities to gradually decrease, so that the impurities fall into the collection tank. At the same time, some impurities attached to the filter are shaken off into the collection tank. This avoids the pollution problem caused by the impurities spreading outward from the air outlet on the one hand, and collects the impurities directly into the collection tank on the other hand, reducing the time for additional transportation and cleaning.

[0020] 3. The device is provided with a control mechanism. When the airflow blows down the falling rice, the arc baffle is switched on and off to control the intermittent falling of the rice. The opening angle of the arc baffle can be adjusted to control the falling amount of the rice each time. The intermittent falling helps to maintain the stability of the airflow in the outer shell, avoid airflow turbulence caused by too much material, and ensure that each rice grain has enough opportunity to contact with the airflow, so as to more effectively separate light impurities.

[0021] 4. This device is equipped with a screening mechanism. The rice that has been selected by wind is then screened out with a sieve plate to screen out small rice particles, which can effectively remove small rice particles that do not meet the size requirements. Removing small rice particles by screening can help ensure the consistency of rice particle size. In the subsequent rice husking process, it can avoid the problem of different rice sizes, resulting in low husking efficiency and more broken rice, which helps to improve the overall quality of rice.

[0022] 5. The device is provided with a spreading component, which throws the selected rice onto the surface of the sieve plate through the rotating blades, so that the rice can be distributed more evenly on the sieve plate, increasing the chance of each particle contacting the sieve hole, so that the rice can be screened out quickly, avoiding the problem of rice accumulating on the sieve plate due to slow screening speed.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0037] See also Figure 1 , Figure 2 , Figure 3 and Figure 5The air selection mechanism 2 includes an outer shell 21 fixedly connected to the top of the bracket 1, an air inlet 22 is opened at one end of the outer shell 21, an air outlet 23 is opened at the other end of the outer shell 21, a feed hopper 28 is fixedly connected to the top of the outer shell 21, a discharge pipe 27 is fixedly connected to the bottom of the outer shell 21, a fan 24 is rotatably connected to the air inlet 22, a mounting frame 7 is fixedly connected to the side of the outer shell 21, a motor 26 is fixedly connected to the top of the mounting frame 7, a transmission shaft 25 is fixedly connected to the output end of the motor 26, and a collecting component 29 for collecting shriveled rice is arranged inside the outer shell 21.

[0038] During specific operation, before the paddy rice is processed into rice, the paddy rice is put into the feed hopper 28, and the paddy rice falls from the feed hopper 28 into the outer shell 21. At this time, the motor 26 drives the fan 24 to rotate through the transmission shaft 25, and the rotating fan 24 blows the high-speed airflow from the air inlet 22 to the inside of the outer shell 21, so that the dry particles in the paddy rice are blown to the air outlet 23 by the airflow, thereby removing the empty husks, broken rice, grass clippings and other light impurities in the paddy rice.

[0039] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 The collecting assembly 29 includes a moving frame 291 slidably connected to the inside of the outer shell 21, a filter 292 is fixedly connected to the inside of the moving frame 291, a first connecting rod 295 is fixedly connected to the outside of the moving frame 291, and a first pull rod 296 is fixedly connected to one end of the first connecting rod 295 away from the moving frame 291, and the first pull rod 296 is slidably connected to the outside of the outer shell 21.

[0040] The collecting assembly 29 further includes a collecting groove 293 opened at the bottom of the outer shell 21 . A first collecting frame 294 is slidably connected to the bottom of the collecting groove 293 . The collecting groove 293 is located on the right side of the moving frame 291 .

[0041] During specific operation, after the fan 24 blows away the impurities, a part of the impurities fall directly into the collection tank 293, and the other part of the impurities are blown to the surface of the filter 292 by the airflow. At this time, these impurities are attached to the filter 292, and the first connecting rod 295 and the movable frame 291 are driven by the first pull rod 296 to move back and forth inside the outer shell 21, so that the impurities attached to the surface of the filter 292 are shaken off into the collection tank 293, and the impurities entering the collection tank 293 enter the first collection frame 294. When the first collection frame 294 is full of impurities, the first collection frame 294 can be pulled out and the collected impurities can be processed centrally.

[0042] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7The control mechanism 3 includes an arc-shaped baffle 31 horizontally rotatably connected to the bottom of the feed hopper 28, and second connecting rods 32 are fixedly connected to both ends of the arc-shaped baffle 31. A slide groove 34 is provided at one end of the second connecting rod 32 away from the arc-shaped baffle 31, and a hinge seat 35 is rotatably connected inside the slide groove 34. A reset component 39 for driving the arc-shaped baffle 31 to close is also provided on the outside of the outer shell 21.

[0043] The control mechanism 3 also includes a second pull rod 33 symmetrically slidably connected to the outside of the outer shell 21. The two second pull rods 33 are fixedly connected with a threaded section 37 at one end close to the hinge seat 35. The threaded section 37 slides through the hinge seat 35. The threaded sections 37 on both sides of the hinge seat 35 are threadedly connected with nuts 38. The threaded section 37 is fixedly connected to the first pull rod 296 at one end away from the second pull rod 33.

[0044] One end of the two second pull rods 33 away from the threaded section 37 is fixedly connected to a cross rod 36 , and the middle portion of the cross rod 36 slides through the transmission shaft 25 .

[0045] During specific operation, the second connecting rod 32 is pulled to rotate by the second pull rod 33, and the second connecting rod 32 drives the arc baffle 31 to rotate synchronously. At this time, the rotating arc baffle 31 makes the bottom of the feed hopper 28 in an open state, so that rice can fall from the feed hopper 28 into the outer shell 21.

[0046] When the amount of rice that falls each time needs to be controlled, the two nuts 38 can be loosened, and then the hinge seat 35 is pushed on the threaded section 37. At this time, the arc baffle 31 can be deflected synchronously, and finally the two nuts 38 can be tightened.

[0047] See also Figure 4 , Figure 6 , Figure 7 and Figure 8 The reset assembly 39 includes a rotating disk 391 fixedly connected to the outside of the transmission shaft 25, and a wedge block 392 is symmetrically fixedly connected to the side of the rotating disk 391 close to the cross bar 36. A first spring 393 is sleeved on the outside of the transmission shaft 25, and one end of the first spring 393 abuts against the side of the cross bar 36 away from the rotating disk 391, and the other end of the first spring 393 is fixedly connected to the outer shell 21.

[0048] During specific operation, while the motor 26 drives the transmission shaft 25 to rotate, the transmission shaft 25 drives the rotating disk 391, and the rotating disk 391 pushes the cross bar 36 to move in the direction close to the outer shell 21 through the two wedge blocks 392. At the same time, the cross bar 36 squeezes the first spring 393, and the cross bar 36 synchronously drives the second pull rod 33 to move. The moving second pull rod 33 drives the arc baffle 31 to rotate through the second connecting rod 32. Similarly, when the second pull rod 33 moves, it synchronously drives the first pull rod 296 to move. When the first pull rod 296 moves, it synchronously drives the first connecting rod 295 to move. When the first connecting rod 295 moves, it synchronously drives the moving frame 291 and the filter screen 292 to move. Finally, the squeezed first spring 393 pushes the cross bar 393 in the opposite direction. 6 moves in the direction away from the outer shell 21. At this time, the cross bar 36 synchronously drives the second pull rod 33 to move in the opposite direction. The second pull rod 33 that moves in the opposite direction drives the arc baffle 31 to rotate through the second connecting rod 32 to close the bottom of the feed hopper 28, thereby realizing the intermittent closing of the feed hopper 28 and controlling the intermittent falling of rice into the outer shell 21. Similarly, when the second pull rod 33 moves in the opposite direction, it synchronously drives the first pull rod 296 to move in the opposite direction. When the first pull rod 296 moves in the opposite direction, it synchronously drives the first connecting rod 295 to move in the opposite direction. When the first connecting rod 295 moves in the opposite direction, it synchronously drives the moving frame 291 and the filter screen 292 to move in the opposite direction. In this way, the filter screen 292 can move back and forth, thereby shaking off impurities attached to the filter screen 292.

[0049] See also Figure 1 , Figure 2 , Figure 5 and Fig. 9 The screening mechanism 4 includes a mounting rod 41 rotatably connected to the outer shell 21, an outer frame 42 is rotatably connected to the bottom of the mounting rod 41, a sieve plate 43 is fixedly connected inside the outer frame 42, a second collecting frame 44 is slidably connected to the bottom of the outer frame 42, and a spreading component 60 is provided at the bottom of the discharge pipe 27 to evenly disperse the rice onto the sieve plate 43.

[0050] The screening mechanism 4 also includes a sliding rod 45 vertically slidably connected to the mounting frame 7, both ends of the sliding rod 45 are fixedly connected to extrusion plates 47, a second spring 48 is sleeved on the outside of the sliding rod 45, one end of the second spring 48 is fixedly connected to the extrusion plate 47 at the top of the sliding rod 45, and the other end of the second spring 48 is fixedly connected to the mounting frame 7, a cam 46 is fixedly connected to the outside of the transmission shaft 25, the cam 46 abuts against the extrusion plate 47 at the top of the sliding rod 45, a first connecting rod 49 is rotatably connected to the outside of the outer frame 42, the first connecting rod 49 is rotatably connected to the second connecting rod 50 at one end away from the outer frame 42, the second connecting rod 50 is rotatably connected to the mounting frame 7 at one end away from the first connecting rod 49, and the first connecting rod 49 and the second connecting rod 50 are located directly below the extrusion plate 47 at the bottom of the sliding rod 45.

[0051] During specific operation, when the motor 26 drives the transmission shaft 25 to rotate, the cam 46 outside the transmission shaft 25 rotates synchronously, and the rotating cam 46 pushes the extrusion plate 47 on the top of the slide rod 45, thereby squeezing the slide rod 45 downward. During the downward movement of the slide rod 45, the extrusion plate 47 at the bottom of the slide rod 45 pushes the first connecting rod 49 and the second connecting rod 50, so that the first connecting rod 49 and the second connecting rod 50 rotate, thereby using the first connecting rod 49 and the second connecting rod 50 to push the outer frame 42 to move to one side. Similarly, when the second spring 48 pushes the slide rod 45 to move upward, the extrusion plate 47 at the bottom of the slide rod 45 The pressing plate 47 releases the squeezing of the first connecting rod 49 and the second connecting rod 50. At this time, the connection between the first connecting rod 49 and the second connecting rod 50 bends upward, and the outer frame 42 moves to the other side under the action of gravity, so that the outer frame 42 swings back and forth left and right, and the rice that has fallen on the surface of the sieve plate 43 is sieved. The rice that has been selected by wind is then passed through the sieve plate 43 to sieve out small particles of rice, which can effectively remove small particles of rice that do not meet the requirements. The small particles of rice enter the second collecting frame 44 and are collected and processed collectively, and the qualified rice slides from one side of the outer frame 42 into the collection container.

[0052] See also Figure 5 , Figure 6 and Fig. 9 The material spreading assembly 60 includes a rotating shaft 602 which is horizontally rotatably connected to the bottom of the discharge pipe 27, a plurality of blades 603 are fixedly connected to the outer side of the rotating shaft 602, a discharge port 601 is opened on the side of the discharge pipe 27, and a driven gear 605 is fixedly connected to the extended end of the rotating shaft 602. A driving gear 604 is rotatably connected to the side of one of the mounting rods 41, and the driving gear 604 and the driven gear 605 are connected by a chain 606. The driving gear 604 is fixedly connected to a ratchet 607, and a pawl 608 is rotatably connected to the side of the mounting rod 41, and the pawl 608 is meshed with the ratchet 607. A metal spring 609 is fixedly connected to the side of the mounting rod 41, and the metal spring 609 conflicts with the pawl 608.

[0053] During specific operation, when the outer frame 42 swings back and forth left and right, the outer frame 42 also drives the mounting rod 41 to swing synchronously. When the mounting rod 41 moves to one side, it drives the pawl 608 to rotate synchronously. At this time, the pawl 608 will not drive the ratchet 607 to rotate, but when the outer frame 42 drives the mounting rod 41 to move to the other side, the pawl 608 will drive the ratchet 607 to rotate synchronously. At this time, the ratchet 607 can rotate synchronously under the restriction of the pawl 608. Since the ratchet 607 is fixedly connected to the driving gear 604, when the ratchet 607 rotates, it drives the driving gear 604 to rotate synchronously. The driving gear 604 drives the driven gear 605 to rotate through the chain 606, and the driven gear 605 drives the rotating shaft 602 to rotate as well. The rotating shaft 602 drives the blade 603 to rotate, so that the blade 603 throws the rice in the discharge pipe 27 from the discharge port 601 to the surface of the screen plate 43.

[0054] Working principle:

[0055] The rice is put into the feed hopper 28, and the rice falls through the air separation mechanism 2 to remove empty husks, broken rice, grass clippings and other light impurities in the rice. The removed impurities are collected and processed by the collecting component 29. When the rice falls from the feed hopper 28, the control mechanism 3 controls the rice to fall intermittently. The rice that has been air-selected also enters the discharge pipe 27, and is scattered from the discharge pipe 27 onto the surface of the screen plate 43 by the spreading component 60, and then the small rice particles that do not meet the requirements are removed by the screening mechanism 4.
