Description

Technical Field

[0001] The utility model belongs to the technical field of rice polishing, and in particular relates to a polishing device for rice processing. Background Art

[0002] After brown rice is milled, a small amount of bran powder still remains on the surface of the rice grains, which affects the appearance quality, storage quality and taste of the rice. By adding an appropriate amount of water for "polishing", it is helpful to completely remove the rice bran on the surface of the rice grains, and it can also gelatinize the starch on the surface of the rice grains, improve the smoothness of the rice, and improve the appearance of the rice while facilitating its preservation.

[0003] In the prior art, after searching Chinese patent number CN212524208U, a rice processing and polishing device is disclosed; it includes a material storage box, a polishing box and a water collecting box, a reserved cavity is provided at the bottom of the material storage box, a filter screen is fixed to the top of the reserved cavity by bolts, fans are installed at both ends of the material storage box through mounting grooves, a No. 1 protective net is fixed to one side of the fan by bolts, and a waterproof and breathable membrane is glued to one side of the No. 1 protective net, a polishing box is installed on the top of the material storage box through a mounting frame, a stirring motor is fixed to the top of the polishing box by bolts, a water pump is fixed to one end of the top of the polishing box by bolts, a feed connecting pipe is fixed to the other end of the top of the polishing box by bolts, and a storage hopper is welded on the top of the feed connecting pipe. The utility model sprays water on the rice in the rice mixing project so that it can be evenly mixed with water, and can air-dry the polished rice at the same time, which is suitable for being widely promoted and used.

[0004] When polishing rice, most of the rice is piled up when it is loaded, which easily causes a part of the rice to accumulate at the bottom of the polishing chamber and not be polished. The above scheme drives the unloading drum to pour the rice into the polishing box through a small motor, and drives the stirring rod to stir the rice through a stirring motor. However, there is a lot of rice accumulated in the polishing box, so that the stirring rod cannot fully stir the rice accumulated at the bottom of the polishing box when it rotates, resulting in poor polishing effect.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] A driving assembly 6 is fixedly installed on one side of the box body 1, a polishing assembly 7 is fixedly installed inside the box body 1, one end of the polishing assembly 7 is fixedly connected to the output end of the driving assembly 6, and a feeding assembly 8 is rotatably provided on the other end of the polishing assembly 7.

[0031] When in use, the rice to be polished is poured into the interior of the hopper 2. Since the hopper 2 passes through the box body 1, one end of the hopper 2 is arranged to be sleeved with the top end of the first conveying component 3, so that the rice can fall to the top end of the first conveying component 3 through the hopper 2, and then the first conveying component 3 is started to drive the rice to be uniformly transported. At the same time, the external drinking water is connected to the water spray component 4, and the rice transported at the top end of the first conveying component 3 is uniformly moistened by starting the water spray component 4. Since the feeding component 8 is arranged below the conveying end of the first conveying component 3, the rice transported at the top end falls into the interior of the feeding component 8 under the continuous transportation of the first conveying component 3. The polishing cylinder 704 is driven to rotate by starting the driving component 8 in cooperation with the output end, and the first motor 701 is started to drive the rotating shaft 702 to rotate, so that The rotating shaft 702 can drive the polishing roller 703 fixedly installed on the outer surface to rotate. Since the polishing cylinder 704 and the rotating shaft 702 are two driving sources, they can rotate in opposite directions. Since the interior of the feeding component 8 is connected to the interior of the polishing component 7, the rice inside the feeding component 8 can enter the interior of the polishing cylinder 704 for polishing. When polishing is completed, the discharge pipe 705 fixedly installed at the bottom of the polishing cylinder 704 is driven by controlling the driving component 8 to move to the top of the second conveying component 5, and then the solenoid valve arranged inside the discharge pipe 705 is started to open the discharge pipe 705, so that the polished rice inside the polishing cylinder 704 cooperates with the discharge pipe 705 to fall to the top of the second conveying component 5, and the rice is transported to the outside of the box body 1 by starting the second conveying component 5.

[0032] The utility model starts the driving component 8 to cooperate with the output end to drive the polishing cylinder 704 to rotate, and at the same time starts the first motor 701 to drive the rotating shaft 702 to rotate, so that the rotating shaft 702 can drive the polishing roller 703 fixedly installed on the outer surface to rotate. Since the polishing cylinder 704 and the rotating shaft 702 are two driving sources, they are rotated in opposite directions. Since the interior of the feeding component 8 is connected with the interior of the polishing component 7, the rice inside the feeding component 8 can enter the interior of the polishing cylinder 704 for polishing. Since the polishing cylinder 704 rotates under the action of the driving component 8, the rice inside the polishing cylinder 704 can be driven to roll upward under the action of the centrifugal force generated by its rotation, and then cooperate with the polishing roller 703 to rotate in the opposite direction inside the polishing cylinder 704, so that the rice inside the polishing cylinder 704 can be fully stirred, thereby improving the polishing effect of the polishing device for rice processing.

[0033] In one embodiment, for the above-mentioned first conveying component 3, the first conveying component 3 includes a first conveyor belt 301, a first baffle 302 is fixedly installed on the top of the first conveyor belt 301, a mounting frame 303 is fixedly connected to the top of the first baffle 302, the top of the mounting frame 303 is fixedly installed on the inner wall of the box body 1, the top of the first conveyor belt 301 is fixedly connected to a flow limiting frame 304, and the interior of the flow limiting frame 304 is socketed with the outer surface of the hopper 2.

[0034] A limiting flow groove is opened on one side of the flow limiting frame 304, so when the rice inside the hopper 2 enters the interior of the flow limiting frame 304, it will not flow out under the rice's own gravity. When the first conveyor belt 301 is started to transport the top rice, the friction force can drive the top rice to evenly pass through the flow limiting groove opened on one side of the flow limiting frame 304, thereby transporting the rice with uniform thickness.

[0035] In one embodiment, for the above-mentioned water spray assembly 4, the water spray assembly 4 includes a water pump 401, a water spray pipe 402 is fixedly installed at the water outlet end of the water pump 401, one end of the water spray pipe 402 is fixedly connected to a water distribution pipe 403, and a nozzle 404 is fixedly installed at the bottom end of the water distribution pipe 403.

[0036] The water distribution pipe 403 is fixedly installed on the top of the inner part of the box body 1 and is arranged directly above the first transport component 3. When the first transport component 3 transports rice and passes under the water spraying end of the water spraying component 4, the water pump 401 is connected to the external drinking water by connecting the water pump end to start the water pump 401 to extract drinking water, and spray it from its outlet end to the inside of the water spraying pipe 402. Since one end of the water spraying pipe 402 passes through the box body 1 and is connected to the inside of the water distribution pipe 403, the water source enters the inside of the water distribution pipe 403 through the water spraying pipe 402, and is sprayed from the multiple groups of nozzles 404 arranged at the bottom thereof. The nozzles 404 spray in a mist form, which has a larger coverage area, thereby moistening the rice passing under the nozzles 404, and making the rice moistened more evenly.

[0037] In one embodiment, for the above-mentioned second conveying component 5, the second conveying component 5 includes a second conveying belt 501, a material receiving frame 502 is fixedly installed on the top end of the second conveying belt 501, and a second baffle 503 is fixedly connected to the top end of the second conveying belt 501.

[0038] The second conveying component 2 is arranged at the bottom end of the box body 1 and corresponds to the bottom of the polishing component 7. The polished rice is discharged through the discharge pipe 705 by the polishing component 7, and then the polished rice falls into the inside of the receiving frame 502 and the top of the second conveyor belt 501. By starting the second conveyor belt 501, the polished rice can be transported to the outside of the box body 1, so as to enter the next process. The setting of the second day baffle 503 can limit the rice transported at the top of the second conveyor belt 501, making its transportation process more stable.

[0039] In one embodiment, for the above-mentioned driving component 6, the driving component 6 includes a second motor 601, and a driving gear 602 is fixedly installed on the output end of the second motor 601. The outer surface of the driving gear 602 is meshingly connected with a driven gear 603, and the interior of the driven gear 603 is fixedly connected to the outer wall of the polishing cylinder 704.

[0040] By starting the second motor 601 to drive the driving gear 602 fixedly installed at the output end to rotate, the driving gear 602 drives the driven gear 603 meshing with it to rotate. Since one end of the polishing cylinder 704 is rotatably connected to the inner wall of the box body 1 through a bearing, and the interior of the driven gear 603 is fixedly connected to one end of the polishing cylinder 704, when the driven gear 603 rotates, it can drive the polishing cylinder 704 fixedly connected to its interior to rotate, thereby independently controlling the rotation of the polishing cylinder 704.

[0041] In one embodiment, for the above-mentioned feeding component 8, the feeding component 8 includes a feeding barrel 801, and a feeding screw 802 is rotatably arranged inside the feeding barrel 801, the inner wall of the feeding screw 802 is fixedly connected to the outer surface of the rotating shaft 702, and the top of the feeding barrel 801 is fixedly connected to a feeding hopper 803.

[0042] Since the inner wall of the feeding screw 802 is fixedly connected to the outer surface of the rotating shaft 702, when the first conveying component 3 pours the rice to be polished into the interior of the feeding hopper 803 and enters the interior of the feeding barrel 801 connected to its bottom end, the first motor 701 is started to drive the rotating shaft 702 to rotate, and drives the feeding screw 802 fixedly connected to its outer surface to rotate inside the feeding barrel 801, thereby being able to quantitatively push the rice inside the feeding barrel 801 into the interior of the polishing barrel 704 connected to one end thereof.

[0043] In one embodiment, for the through slot 9 , a through slot 9 is opened on one side of the box body 1 , and one end of the second conveying assembly 5 cooperates with the through slot 9 to extend to the outside of the box body 1 .

[0044] The through slot 9 is opened through one side of the box body 1, so that the second transport component 5 can pass through the through slot 9 and extend to the outside of the box body 1, so that the second transport component 5 can discharge the polished rice out of the box body 1 to enter the next tapping process.

[0045] In summary, with the aid of the above technical solution of the utility model, the rice to be polished is poured into the interior of the hopper 2, and then the rice can fall through the hopper 2 to the top of the first conveyor belt 301. When the first conveyor belt 301 is started to transport the rice at its top, the friction force can drive the rice at its top to evenly pass through the flow limiting groove opened on one side of the flow limiting frame 304, thereby transporting the rice with uniform thickness. When passing under the water spray component 4, the water pump 401 is started to extract drinking water, and the water is discharged from the water spray component 4. The water is sprayed into the water spray pipe 402, and then the water source enters the water distribution pipe 403 through the water spray pipe 402, and is sprayed from the multiple groups of nozzles 404 arranged at the bottom thereof. The nozzles 404 spray in a mist-like manner, so that the coverage area is large, thereby wetting the rice. Under the continuous conveyance of the first conveyor belt 301, the wetted rice is conveyed to the inside of the feeding hopper 803, and enters the inside of the feeding cylinder 801, and then the first motor 701 is started to drive the rotating shaft 702 to rotate, and drive the solid surface of the rotating shaft 702 to rotate. The fixedly connected feeding screw 802 rotates inside the feeding cylinder 801, and can push the rice inside the feeding cylinder 801 quantitatively into the inside of the polishing cylinder 704 connected to one end thereof, and at the same time, the rotating shaft 702 drives the polishing roller 703 to rotate. Since the polishing cylinder 704 rotates under the action of the driving component 8, it can drive the rice inside the polishing cylinder 704 to roll upward under the action of the centrifugal force generated by its rotation, and then cooperate with the polishing roller 703 to rotate in the opposite direction inside the polishing cylinder 704, so that the rice inside the polishing cylinder 704 can be fully stirred to complete the polishing of the rice, and then the driving component 8 is controlled to drive the discharge pipe 705 fixedly arranged at the bottom end of the polishing cylinder 704 to move to the top of the second conveying component 5, and then the solenoid valve arranged inside the discharge pipe 705 is started to open the discharge pipe 705, so that the polished rice inside the polishing cylinder 704 cooperates with the discharge pipe 705 to fall to the top of the second conveying component 5, and the rice is transported to the outside of the box body 1 by starting the second conveying component 5.

[0046] Through the above technical scheme, 1. Start the driving component 8 to cooperate with the output end to drive the polishing cylinder 704 to rotate, and at the same time start the first motor 701 to drive the rotating shaft 702 to rotate, so that the rotating shaft 702 can drive the polishing roller 703 fixedly installed on the outer surface to rotate. Since the polishing cylinder 704 and the rotating shaft 702 are two driving sources, they can be rotated in opposite directions. Since the interior of the feeding component 8 is connected with the interior of the polishing component 7, the rice inside the feeding component 8 can enter the interior of the polishing cylinder 704 for polishing. Since the polishing cylinder 704 rotates under the action of the driving component 8, the rice inside the polishing cylinder 704 can be driven to roll upward under the action of the centrifugal force generated by its rotation, and then Cooperate with the polishing roller 703 to rotate in the opposite direction inside the polishing cylinder 704, so that the rice inside the polishing cylinder 704 can be fully stirred, thereby improving the polishing effect of the polishing device for rice processing; 2. The inner wall of the feeding screw 802 is fixedly connected to the outer surface of the rotating shaft 702, so that when the first conveying component 3 pours the rice to be polished into the interior of the feeding hopper 803 and enters the interior of the feeding cylinder 801 connected to its bottom end, then start the first motor 701 to drive the rotating shaft 702 to rotate, and drive the feeding screw 802 fixedly connected to its outer surface to rotate inside the feeding cylinder 801, so that the rice inside the feeding cylinder 801 can be quantitatively pushed to the interior of the polishing cylinder 704 connected to one end thereof.
