Description

Technical Field

[0001] This utility model belongs to the field of rice hulling technology, and specifically relates to a rice hulling device. Background Technology

[0002] Rice grains consist of the husk, bran, embryo, and endosperm. The purpose of rice processing is to separate the endosperm from the other parts with minimal breakage, producing rice with better eating quality.

[0003] In the prior art, CN218486039U discloses a rice hulling device; it includes a working box, a base fixedly connected to the left side of the working box, a geared motor fixedly connected to the upper end of the base, and a bellows fixedly connected to the inner wall of the working box. This invention, through the coordinated arrangement of the geared motor, crossbar, and one-way blades, allows the lightweight hull to separate from the rice, which falls through a hole into a collection box for collection. A sieve can separate broken rice and fine impurities. A crossbar, cam, and vertical rod can move the horizontal plate and sieve upwards. A push plate, sliding plate, and return spring can reset the horizontal plate and sieve and move them upwards, repeating this cycle. Therefore, the horizontal plate and sieve can vibrate up and down, preventing broken rice and fine impurities from clogging the sieve, increasing the sieving effect, and thus improving the practicality of the device.

[0004] When hulling rice, the rice is poured into the hulling device for hulling. After hulling, the rice passes through the separation chamber and is blown out by the wind, separating the rice husk from the rice. The above method uses a geared motor to drive the crossbar to rotate, which in turn drives the one-way blades to rotate, blowing the mixture of rice and rice husks that fall into the working box. However, the working box is relatively large, and when the one-way blades blow the rice husks, the rice husks are easily scattered inside the working box, making it difficult for the rice husks to accurately enter the collection box through the holes. In addition, the rice husks are easy to fall onto the screen during the scattering process and be discharged from the outlet at the same time as the rice, thus reducing the practicality of the rice hulling device.

[0012] Furthermore, the second drive assembly includes a second motor and a rotating rod. The output end of the second motor is fixedly connected to one end of the rotating rod, and a support plate is fixedly installed at the bottom end of the second motor. One side of the support plate is fixedly connected to one side of the housing.

[0013] An eccentric wheel is fixedly connected to the outer surface of the rotating rod, and a second connecting rod is rotatably connected to the outer surface of the eccentric wheel. A fixed rod is rotatably connected to one end of the second connecting rod, and a fixed frame plate is fixedly connected to both ends of the fixed rod. The top end of the fixed frame plate is fixedly connected to the bottom end of the sieve plate.

[0014] Furthermore, a through groove is provided on one side of the box, and a collection box is slidably connected inside the through groove. A collection hopper is provided on the upper side of the collection box, and the outer surface of the collection hopper is fixedly connected to the inner wall of the box.

[0015] Furthermore, a discharge hole is provided on one side of the box body, and one end of the screen plate extends to the outside of the discharge hole.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model removes hulled rice by pouring it into the body of the hulling device. The mixture of rice and hulls falls onto the surface of the separating drum. Then, the first drive assembly, in conjunction with the rotating shaft, drives the separating drum to rotate, impacting the rice and hull mixture. The blowing assembly blows the flying hulls into the hull tube connected to one side of the bottom of the U-shaped frame and sprays them out. Under the rotation of the separating drum, the spiral conveyor blades push the rice that has fallen into the inner wall of the U-shaped frame, and the rice falls through the rice tube to the top of the diversion plate. The U-shaped frame can separate the rice hull and rice separation stage from the fine screening process of rice, preventing the hulls from falling onto the screening components and causing blockage. It also allows the rice and hulls to be diverted through the hull tube and rice tube respectively, thereby improving the practicality of the rice hulling device.

[0018] 2. This utility model drives a rotating rod to rotate by starting a second motor, which in turn drives an eccentric wheel fixedly connected to its outer surface to rotate. Since the outer surface of the eccentric wheel is rotatably connected to the inside of the second connecting rod, and the inside of the other end of the second connecting rod is rotatably connected to the outer surface of the fixed rod, when the eccentric wheel rotates, one end of the second connecting rod shakes along the rotation trajectory of the eccentric wheel. Consequently, the other end of the second connecting rod drives the fixed rod to shake. Since both ends of the fixed rod are fixedly connected to the bottom of the sieve plate through a fixed frame plate, when the fixed rod shakes, it can drive the sieve plate to shake, thereby finely screening the rice that falls onto the surface of the sieve plate.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Please see Figures 1-4As shown, this utility model is a rice hulling device, including a box body 1. A hulling device body 2 is fixedly installed at the top of the box body 1. A first drive assembly 3 is fixedly installed on one side of the box body 1. A rotating shaft 4 is rotatably connected inside the box body 1. A separating roller 5 is fixedly connected to the outer surface of the rotating shaft 4. A spiral conveying blade 6 is fixedly connected to the outer surface of the separating roller 5. A U-shaped frame 7 is fixedly connected inside the box body 1. A rice husk tube 8 is fixedly connected to the bottom end of the U-shaped frame 7. A rice tube 9 is opened at the bottom end of the U-shaped frame 7. A blowing assembly 10 is fixedly installed on the inner wall of the U-shaped frame 7. A diverter plate 11 is fixedly installed on the inner wall of the box body 1. One end of the first drive assembly 3 is fixedly connected to one end of the rotating shaft 4. A screening assembly 12 is arranged on the lower side of the diverter plate 11. A second drive assembly 13 is fixedly installed inside the box body 1. The second drive assembly 13 is fixedly connected to the screening assembly 12.

[0030] In use, unhulled rice is poured into the hulling device body 2 for hulling. The hulled rice and husk mixture falls through the bottom of the hulling device body 2 into the box 1 and onto the surface of the separating roller 5. Since the surface of the separating roller 5 has slits, it facilitates the entry of rice and husks into the separating roller 5. The first drive assembly 3 drives the rotating shaft 4 to rotate. Because the outer surface of the rotating shaft 4 is fixedly connected to the inside of the separating roller 5, the rotation of the rotating shaft 4 drives the separating roller 5 to rotate. During the rotation of the separating roller 5, it impacts the rice and husk mixture falling onto the outer surface of the separating roller 5, causing the rice to fall quickly to the inside of the U-shaped frame 7. The husks fly inside the separating roller 5. The blowing assembly 10 generates wind to blow the flying husks inside the separating roller 5 to the other end of the separating roller 5. Because the U-shaped frame 7 is located on the outside of the separating roller 5, the husks can enter... The rice husks are blown into the rice husk tube 8 connected to the bottom of the U-shaped frame 7 by the wind and sprayed out. The rice husks are collected by a collection bag or other holding device placed on the outside of the rice husk tube 8. At the same time, the rice passes through the separating roller 5 and falls into the inner wall of the U-shaped frame 7. The rotation of the separating roller 5 drives the spiral conveyor blade 6 fixedly connected to its surface to rotate. The surface of the spiral conveyor blade 6 is set to rotate in close contact with the inner wall of the U-shaped frame 7. The separating roller 5 drives the spiral conveyor blade 6 to push the rice on the inner wall of the U-shaped frame 7, so that the rice enters the rice tube 9 connected to the bottom of the U-shaped frame 7 and falls onto the surface of the diversion plate 11. Since the diversion plate 11 is inclined, the rice can flow downwards under its own weight and fall onto the top of the screening component 12. The second drive component 13 is activated to drive the screening component 12 to screen the rice, thereby filtering out debris, small stones and other impurities.

[0031] This invention removes the husks from the rice by pouring unhulled rice into the body 2 of the hulling device. The rice and husk mixture falls onto the surface of the separating drum 5. Then, the first drive assembly 3, in conjunction with the rotating shaft 4, drives the separating drum 5 to rotate, impacting the rice and husk mixture. The blowing assembly 10 blows the flying husks into the rice husk tube 8 connected to one side of the bottom of the U-shaped frame 7 and sprays them out. Under the rotation of the separating drum 5, the spiral conveyor blade 6 pushes the rice that has fallen into the inner wall of the U-shaped frame 7, and the rice falls through the rice tube 9 to the top of the diversion plate 11. The U-shaped frame 7 can separate the rice husk separation stage from the rice fine screening process, preventing the rice husks from falling onto the screening assembly 12 and causing blockage. It also allows the rice and husks to be diverted through the rice husk tube 8 and the rice tube 9 respectively, thereby improving the practicality of the rice hulling device.

[0032] In one embodiment, for the first motor 301, the first drive assembly 3 includes the first motor 301, the output end of the first motor 301 is provided with a first connecting rod 302, and a mounting plate 303 is fixedly installed on one side of the first motor 301.

[0033] One side of the mounting plate 303 is fixedly installed on one side of the housing 1, and one end of the first connecting rod 302 passes through the interior of the housing 1 and is fixedly connected to one end of the rotating shaft 4. Thus, when the first motor 301 is started to drive the first connecting rod 302 to rotate, it can drive the rotating shaft 4 to rotate. The mounting plate 303 and the first motor 301 are fixedly installed with bolts, which makes it convenient for staff to install or maintain them.

[0034] In one embodiment, for the above-mentioned air collecting duct 1001, the air blowing assembly 10 includes an air collecting duct 1001, an air inlet 1002 is provided inside the air collecting duct 1001, and a fan blade 1003 is rotatably arranged inside the air collecting duct 1001, and the inside of the fan blade 1003 is fixedly connected to the outer surface of the rotating shaft 4.

[0035] The outer surface of the air collecting duct 1001 is in contact with the inner wall of the U-shaped frame 7 and is fixedly connected to the inner wall of the box 1. The air inlet 1002 passes through the air collecting duct 1001 and the box 1, so that the inside of the air collecting duct 1001 is connected to the outside of the box 1. Thus, when the first drive assembly 3 is started to drive the rotating shaft 4, since the inside of the fan blade 1003 is fixedly connected to the outer surface of the rotating shaft 4, the rotating shaft 4 can drive the fan blade 1003 to rotate. This, together with the air collecting duct 1001, blows air into the inside of the separating drum 5, causing the rice husks inside the separating drum 5 to be blown into the inner wall of the U-shaped frame 7 at the end away from the blowing assembly 10, thus completing the separation of rice husks and rice.

[0036] In one embodiment, for the sieve plate 1201, the screening assembly 12 includes the sieve plate 1201, the top end of the sieve plate 1201 is fixedly connected to a baffle 1202, one side of the baffle 1202 is fixedly connected to a first support rod 1203, the surface of the first support rod 1203 is rotatably connected to a third connecting rod 1204, one end of the third connecting rod 1204 is rotatably connected to a second support rod 1205, and one end of the second support rod 1205 is fixedly connected to the inner wall of the housing 1.

[0037] The baffle 1202 is designed to restrict rice grains falling onto the surface of the sieve plate 1201, preventing them from falling onto the outside of the sieve plate 1201. Four sets of the first support rod 1203, the third connecting rod 1204, and the second support rod 1205 are symmetrically fixed to opposite sides of the two sets of baffles 1202. When the sieve plate 1201 shakes and moves the baffles 1202, the two sets of baffles 1202 move the first support rod 1203 fixed on one side. Since the second support rod 1205 is fixedly connected to the inner wall of the housing 1, and the two ends of the third connecting rod 1204 are rotatably connected to the outer surfaces of the first support rod 1203 and the second support rod 1205 respectively, the sieve plate 1201 can shake in a fixed direction, thereby improving the stability of the sieve plate 1201.

[0038] In one embodiment, for the second motor 1301, the second drive assembly 13 includes the second motor 1301 and the rotating rod 1302. The output end of the second motor 1301 is fixedly connected to one end of the rotating rod 1302. A support plate 1303 is fixedly installed at the bottom end of the second motor 1301. One side of the support plate 1303 is fixedly connected to one side of the housing 1.

[0039] An eccentric wheel 1304 is fixedly connected to the outer surface of the rotating rod 1302. A second connecting rod 1305 is rotatably connected to the outer surface of the eccentric wheel 1304. A fixed rod 1306 is rotatably connected to one end of the second connecting rod 1305. A fixed frame plate 1307 is fixedly connected to both ends of the fixed rod 1306. The top end of the fixed frame plate 1307 is fixedly connected to the bottom end of the sieve plate 1201.

[0040] By starting the second motor 1301, the rotating rod 1302 is driven to rotate, causing the rotating rod 1302 to drive the eccentric wheel 1304 fixedly connected to its outer surface to rotate. Since the outer surface of the eccentric wheel 1304 is rotatably connected to the inside of the second connecting rod 1305, and the inside of the other end of the second connecting rod 1305 is rotatably connected to the outer surface of the fixed rod 1306, when the eccentric wheel 1304 rotates, one end of the second connecting rod 1305 is driven to sway along the rotation trajectory of the eccentric wheel 1304. Consequently, the other end of the second connecting rod 1305 drives the fixed rod 1306 to sway. Since both ends of the fixed rod 1306 are fixedly connected to the bottom of the sieve plate 1201 through the fixed frame plate 1307, when the fixed rod 1306 sways, it can drive the sieve plate 1201 to sway, thereby finely sieving the rice that falls onto the surface of the sieve plate 1201.

[0041] In one embodiment, for the aforementioned through groove 14, a through groove 14 is provided on one side of the box body 1, a collection box 15 is slidably connected inside the through groove 14, a collection hopper 16 is provided on the upper side of the collection box 15, and the outer surface of the collection hopper 16 is fixedly connected to the inner wall of the box body 1.

[0042] The rice is finely sieved by the shaking of the sieve plate 1201. Small stones or debris mixed in with the rice and of relatively heavy weight can pass through the sieve holes at the top of the sieve plate 1201 and fall into the collection hopper 16. Since the bottom of the collection hopper 16 is through-hole and a collection box 15 is set below the collection hopper 16, the small stones or debris fall into the collection box 15 for collection. Since a through groove 14 is provided on one side of the box body 1, it is convenient for the collection box 15 to pass through the through groove 14 and enter the box body 1, so that the staff can clean up the small stones or debris that fall into the collection box 15 in a timely manner.

[0043] In one embodiment, for the discharge hole 17, the discharge hole 17 is provided on one side of the box body 1, and one end of the screen plate 1201 extends to the outside of the discharge hole 17.

[0044] The discharge hole 17 is wider and higher than the sieve plate 1201, and the sieve plate 1201 extends beyond the outer side of the discharge hole 17, making it easier for workers to collect the sieved rice with tools.

[0045] In summary, by means of the above-mentioned technical solution of this utility model, unhulled rice is poured into the body 2 of the hulling device for hulling. The hulled rice and rice husk mixture falls from the bottom of the body 2 onto the surface of the separating drum 5. The first motor 301 is started to drive the first connecting rod 302 to rotate, which in turn drives the rotating shaft 4 and the separating drum 5 to rotate. The separating drum 5 impacts the rice and rice husk mixture, causing the rice to fall quickly to the inside of the U-shaped frame 7. The rice husks fly inside the separating drum 5. The rotating shaft 4 drives the fan blades 1003 to rotate, blowing air into the inside of the separating drum 5, causing the rice husks inside the separating drum 5 to be blown into the rice husk tube 8 and sprayed out. At the same time, when the separating drum 5 rotates, it drives the spiral conveyor blades. 6. The rice on the inner wall of the U-shaped frame 7 is pushed into the rice tube 9 and falls onto the surface of the diversion plate 11. The diversion plate 11 diverts the falling rice to the top of the sieve plate 1201. At the same time, the second motor 1301 is started to drive the rotating rod 1302 to rotate, which in turn drives the eccentric wheel 1304 to rotate. When the eccentric wheel 1304 rotates, one end of the second connecting rod 1305 shakes along the rotation trajectory of the eccentric wheel 1304. Then, the other end of the second connecting rod 1305 drives the fixed rod 1306 to shake. Thus, when the fixed rod 1306 shakes in conjunction with the fixed frame plate 1307, it can drive the sieve plate 1201 to shake, thereby finely screening the rice that falls onto the surface of the sieve plate 1201.

[0046] Through the above technical solution, 1. By pouring unhulled rice into the body 2 of the hulling device for hulling, the rice and husk mixture falls onto the surface of the separating drum 5. Then, the first drive assembly 3, in conjunction with the rotating shaft 4, drives the separating drum 5 to rotate, impacting the rice and husk mixture. The blowing assembly 10 blows the flying husks into the rice husk tube 8 connected to the bottom side of the U-shaped frame 7 and sprays them out. Under the rotation of the separating drum 5, the spiral conveyor blade 6 pushes the rice that has fallen into the inner wall of the U-shaped frame 7, and the rice falls through the rice tube 9 to the top of the diversion plate 11. The U-shaped frame 7 can separate the rice husk and rice separation stage from the rice fine screening process, preventing the rice husks from falling onto the screening assembly 12 and causing blockage. It can also divert the rice and rice husks through the rice husk tube 8 and the rice tube 9 respectively, thereby improving the rice hulling efficiency. 1. Practicality of the shell device; 2. By starting the second motor 1301, the rotating rod 1302 is driven to rotate, which causes the rotating rod 1302 to drive the eccentric wheel 1304 fixedly connected to its outer surface to rotate. Since the outer surface of the eccentric wheel 1304 is rotatably connected to the inside of the second connecting rod 1305, and the inside of the other end of the second connecting rod 1305 is rotatably connected to the outer surface of the fixed rod 1306, when the eccentric wheel 1304 rotates, one end of the second connecting rod 1305 is driven to sway along the rotation trajectory of the eccentric wheel 1304. Then, the other end of the second connecting rod 1305 drives the fixed rod 1306 to sway. Since both ends of the fixed rod 1306 are fixedly connected to the bottom end of the sieve plate 1201 through the fixed frame plate 1307, when the fixed rod 1306 sways, it can drive the sieve plate 1201 to sway, thereby finely sieving the rice that falls onto the surface of the sieve plate 1201.
