Description

Technical Field

[0001] This utility model relates to the field of rice-brown separation technology, and in particular to a rice-brown separation device. Background Technology

[0002] Rice is an important staple food, rich in carbohydrates and providing people with abundant nutrition. In the rice production and processing process, it is very important to separate the brown rice and husk after the rice is hulled. If the brown rice and husk are not completely separated, and the brown rice is directly processed in the next step, it will affect the subsequent processing effect and be detrimental to the quality of the finished rice.

[0003] A search revealed a rice-straw separation device with patent number CN215964683U, comprising a box body. The inner top wall of the box body is provided with a feed hopper extending to its top. The inner top wall of the box body is provided with guide rods located on the left and right sides of the feed hopper. A first screen plate is provided between the left and right sides of the inner wall of the box body and sleeved on the outside of the two guide rods. A first spring is provided between the top of the first screen plate and the inner top wall of the box body and sleeved on the outside of the guide rods.

[0004] However, the above-mentioned rice-husk separation device still has shortcomings. Directly pouring brown rice into the sieve causes the brown rice and husk to pile up together, making it difficult to feed the material evenly and smoothly. This results in feeding too much material at once, which is not conducive to the complete separation of brown rice and husk. At the same time, it is not easy to lift the brown rice and husk, causing them to pile up together and making it difficult to blow out the husk, thus reducing the effect of rice-husk separation. Therefore, we propose a rice-husk separation device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a rice-husk separation device that can feed brown rice evenly and smoothly, which facilitates the rapid screening of brown rice and husks in the later stage, improves the separation efficiency, and can also lift the brown rice and husks to separate them and facilitate the blowing out of the husks, thereby improving the rice-husk separation effect.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a machine body for separating rice husks, a feeding hopper fixedly connected to the top of the machine body, a box fixedly sleeved on the outside of the feeding hopper, a uniform speed feeding mechanism between the box and the feeding hopper, a screen slidably sleeved inside the machine body, a shaking screen mechanism between the screen and the machine body, a lifting mechanism on the machine body above the screen, and rice husk blowing and absorption mechanisms on both sides of the machine body.

[0007] A further feature of this invention is that the uniform speed feeding mechanism includes a partition fixedly connected to the feed hopper and a drive motor fixedly connected to the housing. A turntable is fixedly connected to the output shaft of the drive motor. A push-pull rod is rotatably connected to the front side of the turntable. A movable plate is rotatably connected to one end of the push-pull rod. Feeding holes are provided on the top of both the movable plate and the partition. A sliding plate is fixedly connected to one side of the movable plate.

[0008] By adopting the above technical solution, brown rice is poured into the feeding hopper. The drive motor drives the turntable to rotate, which in turn drives the push-pull rod to reciprocate left and right. The push-pull rod drives the moving plate to reciprocate left and right in the feeding hopper. During the movement, the discharge hole on the moving plate can periodically align with the discharge hole on the partition plate. When aligned, the brown rice can flow out from the discharge hole, making the brown rice feed at a uniform speed. This avoids feeding too much at once, which would be detrimental to the separation of brown rice and husk. Furthermore, the reciprocating motion of the moving plate improves the flowability of the brown rice, making it less prone to clogging.

[0009] A further feature of this invention is that the sliding plate is slidably fitted inside the box, and the movable plate is slidably fitted inside the feed hopper.

[0010] By adopting the above technical solution, it is convenient to guide the moving board and the sliding board, making their movement more stable.

[0011] A further feature of this invention is that a return spring is fixedly connected to one side of the slide plate, and one end of the return spring is fixedly connected to the inner wall of one side of the box.

[0012] By adopting the above technical solution, the initial force is provided to the skateboard under the action of the return spring, making the skateboard and the moving board move more smoothly and preventing them from getting stuck.

[0013] A further feature of this invention is that the toggle mechanism includes an upper motor fixedly connected to one side of the machine body, a rotating shaft fixedly connected to the output shaft of the upper motor, and a plurality of toggle plates fixedly connected to the outer side of the rotating shaft.

[0014] By adopting the above technical solution, the upper motor drives the rotation of the shaft and the agitator, which in turn agitates and lifts the brown rice and husks, thus separating the brown rice and husks and improving the separation effect of brown rice and husks.

[0015] A further feature of this invention is that the husk blowing and absorption mechanism includes a vacuum cleaner fixedly connected to one side of the machine body and a fan fixedly connected to the other side of the machine body. A suction nozzle is fixedly connected to one side of the vacuum cleaner, and the suction nozzle is fixedly installed on the inner wall of one side of the machine body.

[0016] By adopting the above technical solution, the husks in brown rice can be blown out by a fan, and then absorbed into the corresponding recycling point by the suction of a vacuum cleaner, which is convenient for users.

[0017] A further feature of this invention is that the shaking screen mechanism includes four sleeves fixedly connected to the machine body and a lower motor fixedly connected to one side of the machine body. A vertical spring is fixedly connected to the bottom inner wall of the sleeve, a lifting plate is fixedly connected to the top of the vertical spring, and a connecting rod is fixedly connected to the top of the lifting plate. All four connecting rods are fixedly connected to the bottom of the screen. A drive shaft is fixedly connected to the output shaft of the lower motor, and two cams are fixedly sleeved on the outer side of the drive shaft. Both cams movably abut against the bottom of the screen.

[0018] By adopting the above technical solution, the drive shaft and two cams are driven to rotate under the action of the lower motor. When the cam rotates upward, it will drive the screen to move upward and stretch the vertical spring. When the cam rotates downward, the cam does not contact the screen. At this time, under the elastic force of the vertical spring, the screen moves downward and resets, thus forming the screen's up-and-down reciprocating shaking. Under the shaking, not only is the separation of brown rice and husk accelerated, but the brown rice flows down into the collection box for collection and processing, while the husk stays at the top of the screen. Under the blowing of the aforementioned fan and the suction of the vacuum cleaner, the husk can be sucked out for processing, making the separation of rice and brown rice more thorough. At the same time, the shaking can prevent the screen from clogging and improve the screening efficiency.

[0019] A further feature of this invention is that two ear plates are fixedly connected to the inner walls of both sides of the body, and four sleeves are fixedly connected to the top of the corresponding ear plates.

[0020] By adopting the above technical solution, it is convenient to install and fix the four sleeves on the inner walls of both sides of the machine body.

[0021] A further feature of this invention is that the four lifting plates and connecting rods are slidably sleeved in their respective sleeves.

[0022] By adopting the above technical solution, the lifting plate and connecting rod can be guided, making their movement more stable and smooth.

[0023] A further feature of this invention is that an outlet is provided on the front side of the machine body, and a collection box is slidably fitted inside the outlet.

[0024] By adopting the above technical solution, it is convenient to collect and process the sieved brown rice.

[0025] The beneficial effects of this utility model are:

[0026] 1. This utility model uses a drive motor to rotate a turntable, which in turn drives a push-pull rod to reciprocate left and right. The push-pull rod then drives a moving plate to reciprocate left and right within the feed hopper. During this movement, the discharge holes on the moving plate can periodically align with the discharge holes on the partition plate. When aligned, the brown rice can flow out from the discharge holes, ensuring uniform feeding and preventing excessive feeding at once, which would hinder the separation of brown rice from the husks. Furthermore, the reciprocating motion of the moving plate improves the flowability of the brown rice, making it less prone to clogging.

[0027] 2. This utility model uses an upper motor to drive the rotation of the shaft and the agitator, which in turn agitates and lifts the brown rice and husks, separating the brown rice from the husks and improving the separation effect. The fan blows the husks out of the brown rice, and the vacuum cleaner sucks the husks into the corresponding recycling area, making it convenient for users.

[0028] 3. Under the action of the lower motor, this utility model drives the drive shaft and two cams to rotate. When the cams rotate upward, they will drive the screen to move upward and stretch the vertical spring. When the cams rotate downward, the cams do not contact the screen. At this time, under the elastic force of the vertical spring, the screen moves downward and resets, thus forming the screen's up-and-down reciprocating shaking. Under the shaking, not only is the separation of brown rice and husks accelerated, but the brown rice also flows down into the collection box for collection and processing, while the husks remain at the top of the screen. Under the blowing of the aforementioned fan and the suction of the vacuum cleaner, the husks can be sucked out for processing, making the separation of rice and brown rice more thorough. At the same time, the shaking can prevent the screen from clogging and improve the screening efficiency. Attached Figure Description

[0043] Preferably, the shaking screen mechanism includes four sleeves 23 fixedly connected inside the machine body 1 and a lower motor 7 fixedly connected to one side of the machine body 1. A vertical spring 24 is fixedly connected to the bottom inner wall of the sleeve 23. A lifting plate 25 is fixedly connected to the top of the vertical spring 24. A connecting rod 22 is fixedly connected to the top of the lifting plate 25. All four connecting rods 22 are fixedly connected to the bottom of the screen 19. A drive shaft 20 is fixedly connected to the output shaft of the lower motor 7. Two cams 21 are fixedly sleeved on the outer side of the drive shaft 20.

[0044] Preferably, two ear plates are fixedly connected to the inner walls of both sides of the body 1, and four sleeves 23 are fixedly connected to the top of the corresponding ear plates.

[0045] Preferably, the four lifting plates 25 and the connecting rods 22 are slidably sleeved in the corresponding sleeves 23.

[0046] Preferably, the front side of the body 1 has an outlet, and a collection box 2 is slidably fitted inside the outlet.

[0047] In operation, brown rice is poured into the feed hopper 4. The drive motor 8 rotates the turntable 9, which in turn drives the push-pull rod 10 to reciprocate left and right. The push-pull rod 10 then drives the moving plate 12 to reciprocate left and right within the feed hopper 4. During this movement, the discharge holes 11 on the moving plate 12 periodically align with the discharge holes 11 on the partition plate 26. When aligned, the brown rice flows out from the discharge holes 11, ensuring a uniform discharge speed and preventing excessive discharge that would hinder separation of the brown rice and husks. The reciprocating motion of the moving plate 12 also improves the flowability of the brown rice, reducing the likelihood of blockage. Simultaneously, the upper motor 5 drives the rotation of the rotating shaft 15 and the agitator 16, which in turn agitates and lifts the brown rice and husks, separating them so that the blower 17 can easily blow the husks out of the brown rice. Under the suction of the vacuum cleaner 6, the rice husks can be absorbed and collected at the recycling point, making it convenient for users. At the same time, under the action of the lower motor 7, the drive shaft 20 and the two cams 21 are driven to rotate. When the cam 21 rotates upward, it will drive the screen 19 to move upward and stretch the vertical spring 24. When the cam 21 rotates downward, the cam 21 does not contact the screen 19. At this time, under the elastic force of the vertical spring 24, the screen 19 moves downward and resets, thus forming the up and down reciprocating shaking of the screen 19. Under the shaking, not only is the separation of brown rice and rice husks accelerated, but the brown rice flows down into the collection box 2 for collection and processing, while the rice husks stay on the top of the screen 19. Under the blowing of the fan 17 and the suction of the vacuum cleaner 6, the rice husks can be sucked out for processing, making the separation of rice and rice more thorough. At the same time, the shaking can prevent the screen 19 from clogging and improve the screening efficiency.
