Benefits of technology

[0036] 1. This device uses a crushing component to transport the rice from left to right. During transport, the rice husks on the outer surface of the rice are crushed, separating the rice grains from the husks and thus achieving rice dehulling. Most of the dehulled rice husks fall through the filter plate of the sleeve shell onto the deflecting base plate below. Therefore, the mesh of the filter plate is easily blocked by the shell. At this time, the jet concave plate can continuously blow air in the opposite direction to the filter plate that has rotated to the upper part, thereby blowing out the rice husk fragments blocking the mesh of the filter plate and achieving the effect of clearing the mesh of the filter plate. In conjunction with the grinding ring, larger rice husks are further crushed, thus preventing rice husks from clogging the mesh of the filter plate later. This eliminates the need for frequent replacement of related screen components, allowing the device to continuously process large quantities of rice.

Description

Technical Field

[0001] This invention belongs to the field of grain processing technology, specifically a rice milling machine based on rice processing. Background Technology

[0002] Rice is a finished product made from paddy through cleaning, hulling, milling, and finishing processes. It is a staple food for people in most parts of China. Milling is a very important step in rice processing. Brown rice flows into the whitening chamber from the hopper. Due to the internal pressure and mechanical force, the brown rice is squeezed in the whitening chamber. After self-friction and mutual friction between the brown rice and the grinding wheel, the bran of the brown rice can be quickly removed, increasing the grade and whiteness of the rice.

[0003] Existing rice milling machines require transferring the fed paddy rice to a cylinder with a screen structure for dehulling. However, when processing paddy rice continuously, the screen mesh is easily clogged by the rice husks, resulting in poor dehulling effect. Therefore, the screen needs to be replaced frequently after a certain period of use, which makes the equipment operation inconvenient. Therefore, improvements are needed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention to solve its technical problems is: a rice milling machine based on rice processing, comprising a suspension component, a crushing component, a driving component, a feeding component, and a self-cleaning component. The self-cleaning component is symmetrically arranged on both sides of the top of the inner wall of the suspension component. The crushing component is arranged at the lower part of the self-cleaning component. The feeding component is inserted into the left side of the crushing component. The driving component is arranged on the left side of the outer surface of the suspension component.

[0005] The suspension components include containers;

[0006] The lower surface of the container is symmetrically provided with load-bearing feet on the left side, and a load-bearing plate is inserted into the lower surface of the container on the right side.

[0007] The crushing component includes a sleeve shell, an inner rolling shaft, and a rotating ring sleeve;

[0008] The left side of the inner cavity of the sleeve shell is rotatably connected to the inner wall of the rotating ring through an annular groove. The left end of the sleeve shell is inserted into the left side of the inner wall of the container. The rotating ring divides the sleeve shell into left and right cylinders, of which the right cylinder is longer and can rotate along the inner wall of the rotating ring.

[0009] The outer surface of the inner roller shaft is uniformly provided with grinding rings. The grinding rings do not contact the inner wall of the sleeve shell. When rice is added to the inside of the sleeve shell, the grinding rings can squeeze the rice against the inner wall of the sleeve shell, thereby crushing the rice husks on the outer surface of the rice grains. The left end of the inner roller shaft is inserted into the shaft of the drive component, and the right end of the inner roller shaft is rotatably connected to the right side of the inner wall of the container through the shaft.

[0010] A filter plate is evenly inserted into the right side of the inner cavity of the sleeve shell through a slot. After the rice is added into the inside of the sleeve shell through the feeding component, the crushing component transports the rice from left to right while dehulling the rice, and finally discharges the rice grains from the right side of the device.

[0011] Furthermore, the suspension component also includes an upper fixed plate, an inclined frame, and an inner drive shaft:

[0012] The upper fixing plate is inserted into the top of the container cavity, and the left side of the inclined frame is inserted into the left side of the container cavity;

[0013] The outer surface of the inner drive shaft is rolledly connected to the outer surface of the sleeve shell. Rotary motors are symmetrically inserted at both ends of the inner drive shaft, and the outer surface of the rotating motor housing is inserted into the inner wall of the container through a plate.

[0014] Furthermore, the suspension component also includes:

[0015] A ducting fan is provided on the left side of the inner wall of the container, and a baffle plate is provided on the right side of the ducting fan. The bottom of the baffle plate is inserted into the inner wall of the container, and the top of the baffle plate is sleeved with the left end of the outer surface of the sleeve shell through a groove.

[0016] The deflecting bottom plate is rotatably connected to the bottom of the container cavity via a rotating shaft. The lower surface of the deflecting bottom plate is evenly provided with traction handles. The crushed rice husks will fall through the filter plate onto the upper surface of the deflecting bottom plate, and then gather on the left side of the deflecting bottom plate under the action of the wind force of the duct fan.

[0017] A pre-reserved slot is located on the right side of the bottom of the container's inner cavity, and a storage component is installed inside the pre-reserved slot.

[0018] Furthermore, the self-cleaning component includes:

[0019] A pressure-controlled top plate, the lower surface of which is inserted into the upper surface of the upper fixed plate;

[0020] A compression pusher, the top of which is evenly inserted into the bottom of the inner cavity of the pressure control top plate, and the lower part of the compression pusher extends into the interior of the container through a through-hole;

[0021] The spray concave plate has its top cavity inserted into the bottom end of the compression pusher. The spray concave plate has uniformly opened air spray mesh holes in its groove, and the groove on the lower surface of the spray concave plate is pressed against the outer surface of the sleeve shell. The pressure control top plate can extend the compression pusher by pressurizing it, thereby moving the spray concave plate closer to the lower sleeve shell, so that the groove of the spray concave plate is sleeved on the outside of the sleeve shell.

[0022] Furthermore, the driving component includes:

[0023] The main motor has a support platform at its lower part;

[0024] The fan blade shaft has its top end inserted into the shaft inside the duct fan cavity, and its outer surface is rolledly connected to the outer surface of the main motor shaft via a first transmission belt.

[0025] Furthermore, the drive component also includes:

[0026] The drive shaft is symmetrically inserted into the left side of the container's inner cavity. The right end of the drive shaft is inserted into the center of the left end of the inner rolling shaft. A third transmission belt is sleeved on the middle of the outer surface of the drive shaft. The back of the outer surface of the fan blade shaft is rolledly connected to the back of the right drive shaft through a second transmission belt. When the main motor drives the drive shaft to rotate, it drives the fan blade shaft to rotate through the first transmission belt, thereby causing the impeller inside the induced draft fan to rotate, achieving the effect of blowing air to the left. When the fan blade shaft rotates, it also drives the drive shafts on both sides to rotate through the second and third transmission belts, causing the inner rolling shaft inside the sleeve shell to rotate.

[0027] Furthermore, the dispensing component includes:

[0028] The bottom end of the guide frame is inserted into the top of the inner cavity of the guide frame via an insertion interface, and the top end of the guide frame is inserted into the top of the inner cavity of the upper fixing plate.

[0029] Guide baffles are symmetrically arranged at the top of the inner wall of the guide frame shell;

[0030] An internal drive motor is symmetrically inserted into both sides of the inner cavity of the guide frame housing. An impact rod is sleeved on the outer surface of the internal drive motor shaft, and the outer surface of the impact rod is rotatably connected to the inner wall of the guide frame housing.

[0031] Furthermore, the holding component includes:

[0032] A retention frame, the bottom of which is inserted into the inner wall of a pre-reserved slot, a narrow groove is evenly provided on the left side of the inner cavity of the retention frame, and a wide groove is provided on the right side of the inner cavity of the retention frame.

[0033] An inclined sliding plate, the outer surface of which is slidably connected to the inner wall of the retention frame;

[0034] The built-in container plate has its lower surface inserted into the bottom of the inner wall of the retention frame. Control push rods are evenly inserted into the top of the inner cavity of the built-in container plate, and the top of the control push rods is inserted into the lower surface of the inclined slide plate. The built-in container plate can drive the control push rods to slide up and down through an internal driver, thereby shaking the inclined slide plate above. When the inclined slide plate has not slid to the height of the wide-mouth cutting groove, the rice material shaken on the upper surface of the inclined slide plate will be sucked out by the left-side wind force, and the lighter rice husks inside will be discharged through the narrow-mouth cutting groove. Then the inclined slide plate will slide to the height of the wide-mouth cutting groove, and the retained rice material will be discharged from the wide-mouth cutting groove into the interior of the inclined frame.

[0035] The beneficial effects of this invention are as follows:

[0036] 1. This device uses a crushing component to transport the rice from left to right. During transport, the rice husks on the outer surface of the rice are crushed, separating the rice grains from the husks and thus achieving rice dehulling. Most of the dehulled rice husks fall through the filter plate of the sleeve shell onto the deflecting base plate below. Therefore, the mesh of the filter plate is easily blocked by the shell. At this time, the jet concave plate can continuously blow air in the opposite direction to the filter plate that has rotated to the upper part, thereby blowing out the rice husk fragments blocking the mesh of the filter plate and achieving the effect of clearing the mesh of the filter plate. In conjunction with the grinding ring, larger rice husks are further crushed, thus preventing rice husks from clogging the mesh of the filter plate later. This eliminates the need for frequent replacement of related screen components, allowing the device to continuously process large quantities of rice.

[0037] 2. The inner roller shaft rotates the outer surface grinding ring to squeeze the rice material against the inner wall of the sleeve shell, thereby crushing the rice husks. As the sleeve shell rotates continuously due to the driving action of the inner roller shaft during operation, the rice material that accumulates at the bottom axis of the sleeve shell due to gravity can be distributed more evenly in the lower part of the inner wall of the sleeve shell. This avoids the problem of rice material accumulation causing the grinding ring to get stuck and leading to device failure, and also avoids the problem of accumulated rice material crushing the rice grains inside the shell.

[0038] 3. When the rice is fed from the guide frame shell into the inside of the guide frame shell, the rice slides down the guide baffle towards the center. At this time, the impact rod rotates continuously under the drive of the internal drive motor. The rice that is stuck together will be broken up by the impact rod, so that the rice is fed more evenly into the inside of the sleeve shell along the inner wall of the guide frame shell. This prevents the rice from accumulating in a single position and causing the sleeve shell to become blocked. At the same time, the outer shell of the rice is pre-treated to create cracks so that the grinding ring can crush the rice husk more easily.

[0039] 4. The rice grains that have passed through the hulling tray will be transported together with the remaining hulls to the right end outlet of the sleeve shell. In order to ensure the high purity of the collected rice, the rice is not directly put into the inclined frame. Instead, a holding component is set up to collect the batch of rice. Then, through a sieving-like shaking method, the smaller broken hulls in the rice are separated from the rice remaining in the holding frame, realizing a three-stage screening process. After screening, the rice grains are transferred to the inclined frame and then discharged outside the device, thereby effectively reducing the debris mixed in with the rice grains.

[0049] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0050] Example 1, please refer to Figures 1-5 The present invention provides a technical solution: a rice milling machine based on rice processing, including a suspension component 1, a crushing component 2, a driving component 3, a feeding component 4 and a self-cleaning component 5. The self-cleaning component 5 is symmetrically arranged on both sides of the top of the inner wall of the suspension component 1. The crushing component 2 is arranged at the lower part of the self-cleaning component 5. The feeding component 4 is inserted into the left side of the crushing component 2. The driving component 3 is arranged on the left side of the outer surface of the suspension component 1.

[0051] Suspension component 1 includes container 11;

[0052] A load-bearing foot 110 is symmetrically provided on the left side of the lower surface of container 11, and a load-bearing plate 111 is inserted into the right side of the lower surface of container 11.

[0053] The crushing component 2 includes a sleeve shell 21, an inner rolling shaft 24, and a rotating ring sleeve 23;

[0054] The left side of the inner cavity of the sleeve shell 21 is rotatably connected to the inner wall of the rotating ring sleeve 23 through an annular groove. The left end of the sleeve shell 21 is inserted into the left side of the inner wall of the container 11. The rotating ring sleeve 23 divides the sleeve shell 21 into left and right cylinders, of which the right cylinder is longer and can rotate along the inner wall of the rotating ring sleeve 23.

[0055] The outer surface of the inner roller shaft 24 is uniformly provided with grinding rings 25. The grinding rings 25 do not contact the inner wall of the sleeve shell 21. When rice is added to the inside of the sleeve shell 21, the grinding rings 25 can squeeze the rice against the inner wall of the sleeve shell 21, thereby crushing the rice husks on the outer surface of the rice grains. The left end of the inner roller shaft 24 is inserted into the shaft of the drive component 3, and the right end of the inner roller shaft 24 is rotatably connected to the right side of the inner wall of the container 11 through the shaft.

[0056] A filter plate 22 is evenly inserted into the right side of the inner cavity of the sleeve shell 21 through the slot. After the rice is added into the inside of the sleeve shell 21 through the feeding component 4, the crushing component 2 transports the rice from left to right while dehulling the rice, and finally discharges the rice grains from the right side of the device.

[0057] Suspension component 1 also includes an upper fixed plate 12, an oblique frame 14, and an inner drive shaft 13:

[0058] The upper fixing plate 12 is inserted into the top of the inner cavity of the container 11, and the left side of the inclined frame 14 is inserted into the left side of the inner cavity of the container 11.

[0059] The outer surface of the inner drive shaft 13 is rolledly connected to the outer surface of the sleeve shell 21. Rotary motors are symmetrically inserted at both ends of the inner drive shaft 13, and the outer surface of the rotating motor housing is inserted into the inner wall of the container 11 through a plate.

[0060] Suspension component 1 also includes:

[0061] A duct fan 17 is located on the left side of the inner wall of the container 11. A baffle plate 16 is located on the right side of the duct fan 17. The bottom of the baffle plate 16 is inserted into the inner wall of the container 11, and the top of the baffle plate 16 is sleeved with the left end of the outer surface of the sleeve shell 21 through a groove.

[0062] The bottom of the deflecting base plate 18 is rotatably connected to the bottom of the inner cavity of the container 11 via a rotating shaft. The lower surface of the deflecting base plate 18 is evenly provided with traction handles 19. The crushed rice husks will fall through the filter plate 22 onto the upper surface of the deflecting base plate 18, and then gather on the left side of the deflecting base plate 18 under the action of the wind force of the duct fan 17.

[0063] A reserved slot 15 is located on the right side of the bottom of the inner cavity of container 11, and a storage component 6 is installed inside the reserved slot 15.

[0064] Self-cleaning component 5 includes:

[0065] The pressure control plate 51 has its lower surface inserted into the upper surface of the upper fixing plate 12.

[0066] The top of the compression pusher 52 is evenly inserted into the bottom of the inner cavity of the pressure control top plate 51, and the lower part of the compression pusher 52 extends into the interior of the container 11 through the through-hole.

[0067] The top of the jet concave plate 53 is inserted into the bottom of the compression pusher 52. The jet concave plate 53 has uniformly opened jet mesh holes 54 in the groove. The groove on the lower surface of the jet concave plate 53 is pressed against the outer surface of the sleeve shell 21. The pressure control top plate 51 can pressurize the compression pusher 52 to make the compression pusher 52 extend, thereby moving the jet concave plate 53 closer to the lower sleeve shell 21, so that the groove of the jet concave plate 53 is sleeved on the outside of the sleeve shell 21.

[0068] Unhulled rice is fed into the sleeve shells 21 on both sides from the feeding component 4. Then, the driving component 3 drives the inner rolling shaft 24 inside the sleeve shell 21 to rotate synchronously. When the inner rolling shaft 24 rotates, the rice is pushed from left to right along the inner wall of the sleeve shell 21 through the threaded inner rolling shaft 24 on the outer surface. The rice is continuously crushed closer to the inner wall of the sleeve shell 21, thereby crushing the outer shell of the rice. The broken rice husks will fall through the mesh of the filter plate 22 onto the upper surface of the deflection base plate 18.

[0069] When the rice is discharged from the right end of the sleeve shell 21 under the pushing action, the rice will be mixed with some rice husks and thrown away. At this time, the duct fan 17 will generate a right-to-left wind force through the adsorption effect, blowing the lighter rice husks into the deflecting bottom plate 18, while the heavier rice grains will be thrown directly into the interior of the holding component 6. After subsequent processing by the holding component 6, the rice grains are transferred to the interior of the inclined frame 14, and then discharged from the device, thus obtaining the hulled rice.

[0070] After processing, a large amount of rice husks will accumulate on top of the deflection base plate 18. At this time, the operator opens the deflection base plate 18 downwards using the traction handle 19 to pour out the rice husks on the upper surface of the deflection base plate 18. Then, the duct fan 17 blows back to blow away the rice husks remaining on the outer surface of the baffle plate 16 and the upper surface of the deflection base plate 18, thereby achieving the cleaning of the rice husks.

[0071] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: based on embodiment 1, the driving component 3 includes:

[0072] The main motor 31 has a support platform at its lower part.

[0073] The top end of the fan blade shaft 33 is inserted into the shaft inside the duct fan 17, and the outer surface of the fan blade shaft 33 is rolledly connected to the outer surface of the main motor shaft 31 through the first transmission belt 32.

[0074] Drive component 3 also includes:

[0075] The drive shaft 35 is symmetrically inserted into the left side of the inner cavity of the container 11. The right end of the drive shaft 35 is inserted into the center of the left end of the inner rolling shaft 24. A third transmission belt 36 is sleeved on the middle of the outer surface of the drive shaft 35. The back of the outer surface of the fan blade shaft 33 is rolledly connected to the back of the right drive shaft 35 through the second transmission belt 34. When the main motor 31 drives the drive shaft 35 to rotate, it drives the fan blade shaft 33 to rotate through the first transmission belt 32, thereby causing the impeller inside the induced draft fan 17 to rotate, achieving the effect of blowing air to the left. When the fan blade shaft 33 rotates, it will drive the drive shafts 35 on both sides to rotate through the second transmission belt 34 and the third transmission belt 36, causing the inner rolling shaft 24 inside the sleeve shell 21 to rotate.

[0076] Delivery component 4 includes:

[0077] The bottom end of the guide frame 41 is inserted into the top of the inner cavity of the guide frame 41 through the insertion interface, and the top end of the guide frame 41 is inserted into the top of the inner cavity of the upper fixing plate 12.

[0078] Guide baffles 42 are symmetrically arranged on the top of the inner wall of the guide frame shell 41;

[0079] An internal drive motor 43 is symmetrically inserted into both sides of the inner cavity of the guide frame housing 41. An impact rod 44 is sleeved on the outer surface of the shaft of the internal drive motor 43, and the outer surface of the impact rod 44 is rotatably connected to the inner wall of the guide frame housing 41.

[0080] Component 6 of the Sena component includes:

[0081] The bottom of the retention frame 61 is inserted into the inner wall of the reserved slot 15. The left side of the inner cavity of the retention frame 61 is evenly provided with a narrow groove 62, and the right side of the inner cavity of the retention frame 61 is provided with a wide groove 63.

[0082] The inclined slide plate 66 has its outer surface slidably connected to the inner wall of the retention frame 61.

[0083] The built-in container plate 64 has its lower surface inserted into the bottom of the inner wall of the retention frame 61. Control push rods 65 are evenly inserted into the top of the inner cavity of the built-in container plate 64, and the top of the control push rods 65 is inserted into the lower surface of the inclined slide plate 66. The built-in container plate 64 can drive the control push rods 65 to slide up and down through the internal driver, thereby shaking the inclined slide plate 66 above. When the inclined slide plate 66 has not slid to the height of the wide-mouth slit 63, the rice material shaking on the upper surface of the inclined slide plate 66 will be sucked out by the left-side wind force, and the lighter rice husks inside will be discharged through the narrow-mouth slit 62. Then the inclined slide plate 66 will slide to the height of the wide-mouth slit 63, and the retained rice material will be discharged from the wide-mouth slit 63 into the interior of the inclined frame 14.

[0084] When the rice is transferred inside the sleeve shell 21, the pressure control plate 51 pressurizes the compression pusher 52 to push the jet concave plate 53 downward, so that the groove of the jet concave plate 53 fits against the outer surface of the sleeve shell 21. Then, the jet mesh 54 of the jet concave plate 53 blows air from the outside to the inside of the filter plate 22 of the sleeve shell 21. With the effect of the inner drive shaft 13 continuously rotating the sleeve shell 21, the jet concave plate 53 can continuously blow air in the opposite direction to the filter plate 22 that has rotated to the upper part, thereby blowing out the rice husk fragments blocked in the mesh of the filter plate 22 and achieving the effect of clearing the mesh of the filter plate 22.

[0085] When the rice is fed from the guide frame shell 41 into the interior of the guide frame shell 41, the rice slides down the guide baffle 42 towards the center. At this time, the impact rotating rod 44 rotates continuously under the drive of the internal drive motor 43, thereby breaking up the rice that comes into contact with it, so that the rice is fed more evenly into the interior of the sleeve shell 21 along the inner wall of the guide frame shell 41.

[0086] When the rice is discharged from the sleeve shell 21, it enters the interior of the retention frame 61, specifically the upper part of the inclined slide plate 66. Since it is for distributing and feeding rice, the processed rice inside the sleeve shell 21 accumulates on the upper surface of the inclined slide plate 66. Then, the internal loading plate 64 drives the control push rod 65 to reciprocate vertically, thereby shaking the rice on the upper surface by pushing the inclined slide plate 66. During this process, the inclined slide plate 66 is not pushed further... At the height of the wide-mouth slit 63, when the rice grains are shaken, they will be temporarily thrown into the air. At this time, the smaller fragments of the rice grains will be driven by the airflow from the left-side guide fan 17, passing through the narrow-mouth slit 62 and separating from the rice grains retained inside the holding frame 61, thus achieving a three-stage screening process. After screening, the built-in container plate 64 pushes the inclined slide plate 66 to its highest point. At this time, the rice grains on the upper surface of the inclined slide plate 66 will pass through the wide-mouth slit 63 and enter the inclined discharge frame 14, and then be discharged outside the device.

[0087] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
