Description

Technical Field

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

[0002] The rubber roller rice husker is a commonly used rice husking equipment in rice processing. The rubber roller rice husker mainly uses a pair of rubber rollers rotating in opposite directions to realize rice husking. The rice enters the working area between the two rubber rollers. Due to the squeezing and friction of the rubber rollers, the husk of the rice is crushed and separated from the rice. The rubber material on the surface of the rubber roller has a certain elasticity and friction, which can effectively remove the husk without damaging the rice.

[0003] However, during the rice husk husk husk process, the husk is crushed by the rubber rollers, and part of the husk is ground into fine powder. Since the rubber rollers are usually open, and to ensure the smooth rotation of the rubber rollers, there is usually a gap between the rubber rollers and the door of the rice husk husk machine. The powder produced by the rice husk husk husk enters the inner ring surface of the rubber roller through the gap between the rubber roller opening and the door driven by the airflow inside the rice husk husk machine or with the movement of the rice. The rice husk powder entering the inner ring surface increases the friction inside the rubber roller, just like a fine abrasive. During the rotation of the rubber roller, the powder particles will constantly rub against the rubber and metal parts inside the rubber roller, accelerating the wear of the rubber roller and affecting the balance of the rubber roller, that is, the rubber roller will vibrate. The vibration of the rubber roller will make the pressure on the rice during the hulling process unstable, resulting in incomplete hulling. Some rice may only have partially damaged outer shells and not completely separated. The unstable pressure may also cause the rice to be over-extruded and damaged, reducing the quality of the rice and requiring secondary processing, which increases production and time costs.

This helps the rubber roller to provide stable and uniform friction and extrusion when in contact with rice, ensuring the stability and effectiveness of the rice husking process, thereby avoiding more grain particles from getting stuck on the outer ring surface of the rubber roller, which increases the friction of the rubber roller and requires greater motor kinetic energy to drive it; The water stains on the outer ring surface of the rubber roller are absorbed by the sponge sleeve. As the rubber roller continues to rotate, the dryness of the surface of the rubber roller can be ensured, reducing the wear caused by moisture. At the same time, after removing the water stains, the surface of the rubber roller can maintain proper roughness and elasticity. The stable performance of the rubber roller makes the squeezing force on the rice in the rice husking process more balanced and moderate, which helps to reduce the rate of rough and broken rice and further improve the quality and stability of rice husking. Through the squeezing of the pressure plate, it can be ensured that the sponge sleeve always remains dry, and the water stains on the outer ring surface of the rubber roller can be continuously and effectively removed, so that the water absorption process of the sponge sleeve does not need to be interrupted due to water saturation, thereby ensuring the continuity of the operation of the outer ring surface treatment component, which helps the rubber roller to always maintain a good surface condition and mechanical properties.

[0020] The rice husker 11 is provided with an inner ring processing component for removing impurities from the inner ring surface of the rubber roller 12. The inner ring impurity removal component includes two reciprocating screw rods 21, one end of the two reciprocating screw rods 21 is respectively fixedly connected to the inner wall of the two adjacent rubber rollers 12, the other end of the two reciprocating screw rods 21 is respectively fixedly connected to a sleeve plate 22, and the two reciprocating screw rods 21 are respectively slidably connected to a slide plate 23, the bottom ends of the two slide plates 23 are respectively fixedly connected to an upper rotating shaft 24, the bottoms of the two upper rotating shafts 24 are respectively rotatably connected to a lower rotating shaft 25, and the tops of the two lower rotating shafts 25 are respectively fixedly connected to a sleeve 26, and the two sleeves 26 are respectively rotatably connected to the adjacent upper rotating shafts 24. The two sleeves 26 are respectively sleeved on the surfaces of the adjacent reciprocating screw rods 21, and the two reciprocating screw rods 21 are symmetrically sleeved with two dust covers 27, and the ends of the two dust covers 27 on one reciprocating screw rod 21 that are close to each other are rotatably connected to the two sides of the sleeve 26, and the ends of the two dust covers 27 on one reciprocating screw rod 21 that are away from each other are rotatably connected to the sleeve plate 22 and the rice husker 11, and the inner wall of the rice husker 11 is symmetrically fixedly connected with two U-shaped support rods 28, and the tops of the two U-shaped support rods 28 are both extended into the adjacent rubber rollers 12, and the lower surfaces of the tops of the two U-shaped support rods 28 are both in contact with the inner annular surfaces of the adjacent rubber rollers 12, and the tops of the two U-shaped support rods 28 are respectively fixed. A vertical plate 29 is fixedly connected, and the tops of the two vertical plates 29 are slidably connected to the adjacent lower rotating shaft 25. Two slot plates 210 are symmetrically fixedly connected to each of the two vertical plates 29. A track slot 211 is opened on each of the four slot plates 210. A push plate 212 is slidably connected inside each of the four track slots 211. A telescopic tube 213 is fixedly connected to the top surface of each of the four push plates 212. The tops of the four telescopic tubes 213 are fixedly connected to the sleeve 26. The end of the telescopic tube 213 connected to the sleeve 26 is the fixed end, and the end of the telescopic tube 213 connected to the push plate 212 is the telescopic end. The four telescopic tubes 213 are hollow inside, and each of the four telescopic tubes 213 is provided with a A spring 214 is arranged, and the two ends of the four springs 214 are fixedly connected to the adjacent sleeves 26 and the push plates 212. The four push plates 212 are fixedly connected to a poking rod 215 on one side close to the sleeve plate 22. Two debris discharge grooves 216 are symmetrically arranged on the box door 13. The side of the box door 13 away from the rubber roller 12 is symmetrically rotatably connected to two flaps 217. Torsion springs are arranged at the rotational connection between the two flaps 217 and the box door 13. The two flaps 217 correspond to the positions of the two debris discharge grooves 216 respectively. A debris collection box 218 is fixedly connected to the side of the box door 13 close to the flap 217, and a debris discharge door 219 is rotatably connected to the side of the debris collection box 218 away from the box door 13.

[0021] Among them: Reference Fig.10 and Fig.11The track groove 211 is in a right-angle trapezoidal shape, and the inclined surface of the track groove 211 is close to one side of the sleeve plate 22. The track groove 211 is composed of two upper and lower straight grooves, a vertical groove and an inclined groove. There is a height difference between the straight groove and the inclined groove at the bottom of the track groove 211. Specifically, the bottom straight groove of the track groove 211 is high, and the inclined groove is low. When the push plate 212 slides inside the track groove 211 to the intersection of the bottom straight groove and the inclined groove, the push plate 212 will fall into the lower inclined groove. At this time The push plate 212 can only slide upward along the inclined groove, that is, the height difference between the straight groove at the bottom of the track groove 211 and the inclined groove is set to limit the push plate 212 to move only clockwise, acting on the inner ring processing component, specifically: the push plate 212 slides along the bottom of the inner wall of the rubber roller 12 toward the sleeve plate 22. When the push plate 212 slides to the inclined groove of the track groove 211, the push plate 212 will gradually rise in height and will not conflict with the inner wall of the rubber roller 12, thereby preventing impurities inside the rubber roller 12 from being pushed inward.

[0022] Among them: the dust cover 27 is set to be a pleated stacked shape, and the dust cover 27 is made of rubber. The setting function of the dust cover 27 is to prevent impurities inside the rice husker 11 from entering the thread groove of the reciprocating screw 21, ensuring the smooth sliding of the slide plate 23 on the reciprocating screw 21.

[0023] When the door 13 rotates to close the rice husker 11, the two flaps 217 are respectively located on the moving paths of the two poking rods 215 in the two rubber rollers 12, that is, the poking rods 215 can push the flaps 217 to rotate upward.

[0024] Among them: Reference Figure 4 As shown, the bottom of the collecting box 218 is arranged as an inclined surface, so as to facilitate the impurities on the inner annular surface of the rubber roller 12 to enter the interior of the collecting box 218 .

[0025] The top surface of the push plate 212 is configured as an inclined surface inclined toward one side of the sleeve plate 22 , so as to prevent powder impurities from accumulating on the top surface of the push plate 212 .

[0026] When the inner ring processing assembly is running, the rice husker 11 and the two rubber rollers 12 are running to husker the rice. At this time, the box door 13 rotates to close the inside of the rice husker 11.

[0027] At this time, the two rubber rollers 12 are in the process of rotating towards each other, and the U-shaped support rod 28, the vertical plate 29, and the groove plate 210 do not rotate synchronously with the rubber rollers 12. The powder generated during the husking process will enter the inner annular surface of the rubber roller 12 through the gap between the opening of the rubber roller 12 and the box door 13, driven by the internal airflow of the rice husker 11 or with the movement of the rice.

[0028] The powder impurities entering the inner annular surface of the rubber roller 12 will be restricted by the U-shaped support rod 28 , the vertical plate 29 , and the groove plate 210 , so that the powder impurities cannot rotate synchronously with the rubber roller 12 , and are accumulated on both sides of the vertical plate 29 .

[0029] At this time, the rotation of the rubber roller 12 drives the reciprocating screw 21 to rotate synchronously. At this time, the slide plate 23 is on the reciprocating screw 21, and there is a tendency for the reciprocating screw 21 to drive the reciprocating screw 21 to rotate synchronously. However, at this time, the slide plate 23 is limited on the reciprocating screw 21 by the upper rotating shaft 24 and the lower rotating shaft 25, so that the slide plate 23 can only slide along the reciprocating screw 21. Then, when the reciprocating screw 21 rotates, the slide plate 23 slides along the thread groove of the reciprocating screw 21, and the slide plate 23 deflects accordingly along the thread groove of the reciprocating screw 21, so that the slide plate 2 The upper rotating shaft 24 is made to rotate inside the lower rotating shaft 25 through the upper rotating shaft 24, and then with the rotation of the reciprocating screw 21, the lower rotating shaft 25 is in the limit position of the reciprocating screw 21, and the lower rotating shaft 25 reciprocates on the top of the reciprocating screw 21, and then the lower rotating shaft 25 drives the sleeve 26 to reciprocate synchronously, that is, reciprocates from the inside to the outside inside the rubber roller 12, at this time, the sleeve 26 drives the push plate 212 to move synchronously through the telescopic tube 213, and at this time, the push plate 212 slides unidirectionally inside the track groove 211, refer to Fig.11 As shown, at this time, the push plate 212 slides in a clockwise cycle inside the track groove 211. Combined with the above, when the push plate 212 slides from the rubber roller 12 to the sleeve plate 22, the powder impurities accumulated on both sides of the vertical plate 29 will be pushed toward the sleeve plate 22 by the push plate 212, and in this process, the poking rod 215 pushes the flap 217 to rotate upward, and the torsion spring connected to the flap 217 and the box door 13 produces elastic deformation. At this time, the collection box 218 is connected to the inside of the rubber roller 12, and the push plate 212 pushes the powder impurities into the collection box 218. When the poking rod 215 no longer conflicts with the flap 217, the torsion spring of the flap 217 elastically resets, so that the flap 217 covers the impurity discharge groove 216 again, so that the rubber roller 12 is no longer connected to the inside of the collection box 218, thereby preventing the rice that has been husked from entering the collection box 218.

[0030] When the push plate 212 moves in the opposite direction, the push plate 212 enters the top straight groove of the track groove 211. At this time, the telescopic end of the telescopic tube 213 shrinks and the spring 214 is elastically compressed. At this time, the push plate 212 does not conflict with the inner annular surface of the rubber roller 12, avoiding the powder impurities being pushed to the inner side of the rubber roller 12 by the reverse movement of the push plate 212. As the push plate 212 circulates, the powder impurities are pushed into the collection box 218, which can reduce the accumulation of powder impurities inside the rubber roller 12, avoid the friction between the powder particles and the internal components of the rubber roller 12, reduce the wear rate of the rubber roller 12, and thus significantly extend the service life of the rubber roller 12. By continuously removing the powder impurities, the rubber roller 12 can be kept in a good balance state, ensuring that it is more stable during high-speed rotation, thereby maintaining the rice husking accuracy of the rubber roller 12, improving the quality and stability of rice husking, and avoiding the greater power required by the rubber roller 12 due to friction, resulting in greater energy consumption required by the connected motor, thereby saving the energy consumption of the motor.

[0031] The push plate 212 circulates to push the powder impurities into the collecting box 218, so that the powder impurities on the inner ring surface of the push plate 212 are collected in the collecting box 218, thereby realizing independent collection of the removed powder impurities. Independent collection of impurities can prevent the removed powder impurities from re-entering the rice husker 11 and the rubber roller 12, thereby avoiding the circulation and accumulation of powder impurities in the rice husker 11 and the rubber roller 12, reducing the risk of secondary contamination of the rice husker 11 and the rubber roller 12, and further improving the quality and stability of rice husking.

[0032] Reference Figure 4 As shown, when finishing husking rice, the user can rotate the impurity discharge door 219 upward to remove the powder impurities inside the impurity collection box 218.

[0033] Embodiment 2: The rice itself contains a certain amount of moisture. When the rice enters the rice husking machine 11 for husking, the rice contacts the rubber roller 12, and the moisture on its surface will be transferred to the outer ring surface of the rubber roller 12 during the contact and friction process. At the same time, during the husking process, after the husk is broken into smaller fragments, its specific surface area increases, and it is more susceptible to the adsorption force of moisture, thereby adhering to the outer ring surface of the rubber roller 12. Impurities adhering to the outer ring surface of the rubber roller 12 will change the surface properties of the rubber roller 12, and affect the friction and pressure distribution between the rubber roller 12 and the rice. This makes it impossible for the rice to obtain a uniform and stable force during husking, resulting in incomplete husking of the rice, and the husk of some rice grains cannot be completely removed, thereby reducing the husking rate.

[0034] The distribution of water stains will soften the rubber material on the surface of the rubber roller 12 and reduce its wear resistance. It will also affect the friction between the rubber and other components, making the rubber roller 12 more susceptible to wear during rotation, shortening the service life of the rubber roller 12 and affecting the rice husking effect.

[0035] See also Figure 1 , Figure 2 as well as Fig.12 , Fig.13 As shown, in order to solve the above-mentioned problem, two outer annular surface processing components are symmetrically arranged on the rice husker 11, and the outer annular surface processing components include a storage box 31, which is fixedly connected to the side wall of the rice husker 11, and a flap 2 32 is rotatably connected to the outer wall of the rice husker 11 through a torsion spring, and a transverse shaft 33 is rotatably connected to the inner wall of the rice husker 11 on the side close to the rubber roller 12, and a sponge sleeve 34 is sleeved on the outer surface of the transverse shaft 33, and a water baffle 36 is fixedly connected to the top surface of the storage box 31, and two water baffles 36 are fixedly connected to the top surface of the storage box 31 and located on both sides of the pressure plate 35, and a water storage tank 37 is fixedly connected to the top surface of the inner wall of the storage box 31, and a drainage hole is provided on the bottom surface of the water storage tank 37, and a drainage cover 38 is clamped at the bottom of the drainage outlet of the water storage tank 37.

[0036] The top surface of the inner wall of the storage box 31 is in contact with the outer surface of the rubber roller 12, the side wall of the storage box 31 is not in contact with the outer surface of the rubber roller 12, and a through hole is provided on the side wall of the storage box 31 for the impurities scraped off from the top of the storage box 31 to fall.

[0037] Among them: the sponge sleeve 34 is squeezed and matched with the outer ring surface of the rubber roller 12, that is, the sponge sleeve 34 is attached to the outer ring surface of the rubber roller 12, and the sponge sleeve 34 is squeezed and deformed, and the pressure plate 35 is squeezed and matched with the transverse shaft 33, that is, the water retaining plate 36 is attached to the surface of the sponge sleeve 34, and the sponge sleeve 34 is squeezed and deformed.

[0038] Wherein: both ends of the sponge cover 34 are provided with anti-slip grooves arranged in a ring shape.

[0039] Among them: Reference Fig.13 As shown, the top of the sundries storage box 31 is set to be open, and the opening of the sundries storage box 31 is located between the pressure plate 35 and the water retaining plates 36 on both sides.

[0040] During the operation of the outer ring surface treatment component, the rubber roller 12 is in the process of rotating. At this time, the impurities on the outer ring surface of the rubber roller 12 are scraped off by the top of the inner wall of the storage box 31, and the scraped impurities fall on the bottom of the inner wall of the storage box 31. As the rubber roller 12 continues to rotate, the impurities on the outer ring surface of the rubber roller 12 are continuously scraped off by the storage box 31. The scraping of impurities reduces the friction between the impurities and the surface of the rubber roller 12, so that the surface of the rubber roller 12 can always remain relatively clean and smooth, and maintain its original roughness and elasticity. This helps the rubber roller 12 to provide stable and uniform friction and extrusion when in contact with the rice, ensuring the stability and effectiveness of the rice husking process, thereby preventing more grain particles from getting stuck on the outer ring surface of the rubber roller 12, which increases the friction of the rubber roller 12 and requires a larger motor kinetic energy to drive it; the impurities scraped off the outer ring surface of the rubber roller 12 fall to the bottom of the inner wall of the storage box 31. When the rice husking is finished, the user can rotate the flap 2 32 upwards to remove the impurities inside the storage box 31.

[0041] During the rotation of the rubber roller 12, the sponge sleeve 34 relies on the anti-skid grooves at both ends to increase the friction between it and the outer ring surface of the rubber roller 12. At this time, the sponge sleeve 34 drives the transverse shaft 33 to rotate synchronously with the rubber roller 12, and the water stains on the outer ring surface of the rubber roller 12 are absorbed by the sponge sleeve 34. With the continuous rotation of the rubber roller 12, the dryness of the surface of the rubber roller 12 can be ensured, and the wear caused by moisture can be reduced. At the same time, after the water stains are removed, the surface of the rubber roller 12 can maintain appropriate roughness and elasticity and other characteristics, which can make the squeezing force of the rubber roller 12 on the rice during the rice husking process more balanced and moderate, which helps to reduce the rate of rough and broken rice and further improve the quality and stability of rice husking.

[0042] During the process of the sponge sleeve 34 rotating and absorbing the moisture on the outer ring surface of the rubber roller 12, the pressure plate 35 squeezes the sponge sleeve 34 so that the moisture inside the sponge sleeve 34 is squeezed out by the pressure plate 35, and the squeezed moisture flows into the water tank 37 along the surface of the pressure plate 35. During this process, the two water retaining plates 36 on both sides of the pressure plate 35 can prevent the moisture from entering the water tank 37 and splashing into the rice husker 11.

[0043] Furthermore, during the process of the sponge sleeve 34 rotating and absorbing moisture from the outer surface of the rubber roller 12, the squeezing of the pressure plate 35 can ensure that the sponge sleeve 34 always remains dry, and can continuously and effectively remove water stains from the outer surface of the rubber roller 12, so that the water absorption process of the sponge sleeve 34 does not need to be interrupted due to water saturation, thereby ensuring the continuity of the operation of the outer surface treatment component, which helps the rubber roller 12 to always maintain a good surface condition and mechanical properties.

[0044] When finishing husking rice, the user can pull out the drainage cover 38 to drain the water inside the water storage tank 37.
