Description

Technical Field

[0001] This utility model relates to the technical field of rice polishing machines, specifically a high-efficiency, low-energy-consumption rice polishing machine with a auger-free box structure. Background Technology

[0002] Rice polishing machines are a key component of rice processing equipment. They play a crucial role in the rice processing process, effectively removing the bran from the surface of the rice through fine friction, resulting in a smoother and shinier appearance. They also greatly enhance the texture and fineness of the rice.

[0003] When polishing rice, rice polishing machines typically require two polishing processes: initial polishing and fine polishing. The transition from initial polishing to fine polishing involves using a spiral conveyor (or auger) to transport the rice. As described in Chinese patent publication CN2885499Y, a dual-body high-efficiency rice polishing machine with an upper and lower assembly, it consists of: "a rice polishing machine body and an initial polishing machine mounted on the body. Below the initial polishing machine, a fine polishing machine is connected via a spiral conveyor. The semi-finished product from the rice outlet is returned by the spiral conveyor mechanism in the middle of the machine and sent into the fine polishing chamber located below for a second fine polishing."

[0004] Through a search of the aforementioned patents, we found that our solutions, in this regard, still have certain drawbacks. Because the rice requires a screw conveyor for the second polishing process, the conveying distance is increased, indirectly increasing the possibility of rice breakage during transport, which is detrimental to ensuring the integrity of the rice. Furthermore, the operation of the screw conveyor indirectly increases the overall energy consumption and manufacturing cost of the equipment. Based on this, we have specifically designed a high-efficiency, low-energy-consumption rice polishing machine with a screw conveyor-less housing structure. Summary of the Invention

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5A high-efficiency, low-energy-consumption rice polishing machine with a auger-free housing structure includes a main outer shell 1. An upper polishing roller assembly 6 is disposed on the top inner side of the main outer shell 1, and a lower polishing roller assembly 14 is disposed inside the main outer shell 1 at the bottom of the upper polishing roller assembly 6. The upper polishing roller assembly 6 includes an upper polishing roller 601 and a right-handed conveying head 602 fixed to the right side of the upper polishing roller 601. The surface of the upper polishing roller 601 is divided into four equal parts by upper polishing ribs 603. The lower polishing roller assembly 14 includes a lower polishing roller 1401 and a left-handed conveying head 1402 fixed to the left side of the lower polishing roller 1401. The surface of the lower polishing roller 1401 is divided into four equal parts by lower polishing ribs 1403. An upper discharge seat 5 fixed to the main outer shell 1 is rotatably connected to the left side of the upper polishing roller 601, and a lower feed seat 13 fixed to the main outer shell 1 is rotatably connected to the left side of the lower polishing roller 1401. The upper discharge seat 5 and the lower feed seat 13 are connected through a guide assembly.

[0023] Please see Figure 1 In this embodiment, the upper polishing roller 601 is rotatably connected to the upper feed seat 7 fixed on the main housing 1, the top of the upper feed seat 7 is connected to the feed hopper 2 fixed on the top of the main housing 1, and the right-hand conveying head 602 is rotatably installed inside the upper feed seat 7.

[0024] Specifically, the feed hopper 2 is used to feed rice that needs to be polished. The right-handed conveyor head 602 rotates inside the upper feed seat 7, which can transport the rice falling from the feed hopper 2 to the left, so that it contacts the upper polishing rib 603 to achieve the initial polishing.

[0025] Please see Figure 1 In this embodiment, the right side of the lower polishing roller 1401 is rotatably connected to the lower discharge seat 15 fixed on the main housing 1, the bottom of the lower discharge seat 15 is connected to the lower discharge nozzle 16, and the left-hand conveying head 1402 is installed inside the lower feed seat 13.

[0026] Specifically, the lower rice outlet 16 is used to discharge the polished rice for easy collection, while the left-hand rotating conveyor head 1402 rotates inside the lower feed seat 13, so that the rice can be transported from the left to the right, so that the rice can come into contact with the lower polishing rib 1403 to achieve secondary fine polishing.

[0027] Please see Figure 1 In this embodiment, the feeding assembly includes an upper rice outlet 9, a receiving frame 10, and a feeding guide frame 11. The upper rice outlet 9 is fixedly connected to the bottom of the upper feeding seat 5. The receiving frame 10 is fixed to the left side of the main housing 1 and located at the bottom of the upper rice outlet 9. The feeding guide frame 11 is fixedly connected to the top of the lower feeding seat 13, and the feeding end of the feeding guide frame 11 is connected to the discharging end of the receiving frame 10.

[0028] Specifically, the upper rice outlet 9 is used to discharge rice polished by the upper polishing roller 601 and can be guided into the receiving frame 10. Through the transfer of the receiving frame 10, the rice can enter the guide frame 11 and fall from the top of the lower feed seat 13 into the interior for easy transmission by the left-hand conveyor head 1402.

[0029] Please see Figure 1 In this embodiment, a side shell 3 is also provided on the left side of the main shell 1. An upper main shaft pulley 4 and a lower main shaft pulley 12 are provided in the side shell 3. The upper main shaft pulley 4 is connected to the left end of the upper polishing roller 601 through a shaft, and the lower main shaft pulley 12 is connected to the left end of the lower polishing roller 1401 through a shaft.

[0030] Specifically, a drive device (a motor commonly used in the field, which is common knowledge in the field, and whose working principle is known technology; the specific model and specifications can be selected and determined according to the device and actual conditions, so it will not be described in detail) can be installed at the inner bottom of the side housing 3. This device is connected to the upper spindle pulley 4 and the lower spindle pulley 12 by a belt, thereby driving the upper spindle pulley 4 and the lower spindle pulley 12 to rotate, which in turn drives the upper polishing roller 601 and the lower polishing roller 1401 to rotate.

[0031] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, the upper polishing rib 603 is designed as an inclined structure on the upper polishing roller 601, and the lower polishing rib 1403 is provided with two sections on the lower polishing roller 1401. The section of the lower polishing rib 1403 near the left-hand conveying head 1402 is designed as an inclined structure, and the end near the lower discharge seat 15 is designed as a straight structure.

[0032] Specifically, the upper polishing ribs 603 are all inclined, and the angle becomes gentler, resulting in less resistance and a lower breakage rate of rice. The lower polishing ribs 1403 are inclined in one section and straight in another. The inclined section can achieve secondary polishing of the rice, while the straight section can achieve polishing precision of the rice.

[0033] Please see Figure 1 , Figure 4 and Figure 5 In this embodiment, an octagonal screen assembly 8 is installed between the upper discharge seat 5 and the upper feed seat 7, which is sleeved on the outside of the upper polishing roller 601. An octagonal screen assembly 8 is also installed between the lower feed seat 13 and the lower discharge seat 15, which is sleeved on the outside of the upper polishing roller 601. The screen assembly 8 includes a left screen 801 and a right screen 802 that are fixed together by bolts.

[0034] Specifically, the screen assembly 8 consists of two quadrilateral left screens 801 and right screens 802, which are fixed together with bolts, so that the left screens 801 and right screens 802 can be easily separated for cleaning or cleaning the mesh.

[0035] Please refer to the figure. Figure 1 and Figure 4 In this embodiment, a lower bucket 17 is installed inside the main housing 1 and at the bottom of the lower polishing roller assembly 14. A suction pipe 1701 is connected to one side of the lower bucket 17. The end of the suction pipe 1701 away from the lower bucket 17 passes through the main housing 1 and is connected to the external ventilation device.

[0036] Specifically, rice polishing produces rice bran, which falls out through the mesh of the screen assembly 8. Since a lower hopper 17 is provided on the inner bottom wall of the main outer shell 1, and a suction pipe 1701 is connected to the lower hopper 17, and the suction pipe 1701 is connected to an external ventilation device (the ventilation device is a commonly used fan in the field, which is common knowledge in the field, and its working principle is a well-known technology. The specific model and specifications can be selected and determined according to the device and the actual situation, so it will not be described in detail). Thus, the rice bran inside the main outer shell 1 can be quickly extracted by the suction of the ventilation device.

[0037] Please see Figure 2 , Figure 3 and Figure 5 In this embodiment, a ventilation groove 604 is provided on the surface of the upper polishing roller 601 and near each upper polishing rib 603, and a ventilation groove 1404 is provided on the surface of the lower polishing roller 1401 and near each lower polishing rib 1403. A water pipe 18 is inserted into the interior of both the upper polishing roller 601 and the lower polishing roller 1401, and an atomizing nozzle 1801 is connected to the surface of both water pipes 18.

[0038] Specifically, during the polishing process, the water pipe 18 guides the water, and the atomizing nozzle 1801 atomizes and diffuses the water inside the upper polishing roller 601 and the lower polishing roller 1401, and it is emitted from the first ventilation groove 604 and the second ventilation groove 1404 respectively, thereby moisturizing the rice and improving the polishing effect.

[0039] Please see Figure 1 and Figure 4 In this embodiment, the main outer shell 1 and the side outer shell 3 have the same shape, and multiple concave reinforcing plates 19 are welded to the front and back of both the main outer shell 1 and the side outer shell 3.

[0040] Specifically, the concave reinforcing plate 19 has a concave structure that can change the stress distribution of the shell, disperse external pressure to a wider area, improve rigidity, and enhance the stability of the main shell 1 and the side shell 3.

[0041] When using: Rice is fed into the upper feed seat 7 from the feed hopper 2. The right-handed conveyor head 602 rotates to convey the rice. When the rice reaches between the upper polishing roller 601 and the screen assembly 8 sleeved on the outside of the upper polishing roller 601, the upper polishing ribs 603 on the upper polishing roller 601 push the rice and the inner wall of the screen assembly 8 to contact and rub the rice, and convey the rice from right to left to achieve the initial polishing of the rice. Then the rice is discharged from the upper rice outlet 9 into the receiving frame 10, and then into the guide frame 11 before entering the lower feed seat 13. The left-handed conveyor head 1402 conveys the rice from left to right to the lower polishing roller 1401 and the screen assembly 8 sleeved on the outside of the lower polishing roller 1401. During the conveying process, the lower polishing roller 1401 and the lower polishing ribs 1403 perform secondary polishing on the rice. Finally, the rice that has been polished twice is discharged through the lower rice outlet 16.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
