Description
Technical Field
[0001] This utility model relates to the field of food processing technology, and in particular to a rice grain washing device. Background Technology
[0002] Rice is a finished product made from paddy through processes such as cleaning, hulling, milling, and finishing. It is a basic food for supplementing nutrients. In addition to being rich in carbohydrates, it also contains protein, fat, vitamins, and 11 kinds of minerals, which can provide the human body with comprehensive nutrition.
[0003] However, in daily life, rice needs to be washed before processing. The washing method is usually manual, which is not only ineffective but also inefficient. Furthermore, existing washing devices often break the rice grains during washing, causing them to be washed away and wasted. Utility Model Content
[0004] In view of this, the present invention aims to provide a rice grain washing device that can reduce the breakage rate of rice grains and improve the washing effect and efficiency of the device.
[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0006] A rice grain washing device includes a cylindrical shell, a washing tank slidably disposed on the shell, and a water inlet pipe rotatably disposed on the washing tank and extending along the height direction of the shell. The washing tank has a feed inlet at the top and a plurality of first drain outlets arranged at intervals along its circumference at the bottom. The shell has a second drain outlet at the bottom that communicates with each of the first drain outlets. The water inlet pipe has a plurality of stirring plates arranged at intervals along its circumference for stirring the rice grains, and each stirring plate is inclined.
[0007] Furthermore, the water inlet pipe is provided with a plurality of water outlet holes arranged at intervals along its circumference, and each water outlet hole is arranged alternately with each of the stirring plates.
[0008] Furthermore, each of the aforementioned stirring plates is provided with multiple through holes, each of which is used to allow water to flow through, thereby reducing the resistance of the corresponding stirring plate.
[0009] Furthermore, the tilt angle of each of the stirring plates is between 5° and 10°.
[0010] Furthermore, a base plate is rotatably provided on the housing, and a plurality of first arc-shaped protrusions are arranged at intervals along their own circumference on the base plate. The bottom of the cleaning tank is provided with second arc-shaped protrusions that correspond one-to-one with each of the first arc-shaped protrusions. Each of the first arc-shaped protrusions and each of the second arc-shaped protrusions contacts each other in sequence to make the cleaning tank vibrate.
[0011] Furthermore, a mounting bracket is provided on the inner wall of the housing, and a driving component for driving the substrate to rotate is provided on the mounting bracket.
[0012] Furthermore, the bottom of the housing is provided with a conical drainage groove, and the second drainage outlet extends along the height direction of the housing and is arranged at the bottom of the drainage groove, and each of the first drainage outlets is connected to the second drainage outlet through the drainage groove.
[0013] Furthermore, the top of the cleaning tank is provided with a downwardly extending slider, which extends circumferentially along the cleaning tank, and the housing is provided with a sliding groove adapted to the slider, and the cleaning tank slides on the sliding groove via the slider.
[0014] Furthermore, the top of the cleaning tank is provided with a cover plate, and the cover plate is provided with a drive unit for driving the water inlet pipe to rotate; the drive unit includes a first gear sleeved on the water inlet pipe, a second gear meshing with the first gear, and a motor for driving the second gear to rotate.
[0015] Furthermore, a gap is provided between each of the stirring plates and the cover plate, and each gap is used for the rice grains to pass through.
[0016] Compared with the prior art, this utility model has the following advantages:
[0017] The rice washing device described in this utility model can save manpower by setting up a water inlet pipe and various stirring plates on the water inlet pipe. At the same time, the stirring plates are set at an angle to fully stir the rice grains, preventing the rice grains from accumulating at the bottom of the tank and clogging the first drain outlet, thereby improving the washing effect of the device. In addition, it can also prevent the rice grains from being damaged by sudden strong pressure, thereby reducing the breakage rate of rice grains and reducing rice waste.
[0018] Secondly, the multiple water outlets on the inlet pipe allow water to enter the washing tank from different heights and positions, ensuring comprehensive contact with every grain of rice. This achieves a balance between water conservation and increased washing efficiency. Furthermore, the staggered arrangement of the water outlets and the agitator plates effectively cleans the plates. The through-holes reduce the resistance to the rotation of the agitator plates, thus lowering energy consumption. They also ensure ample water flow, guaranteeing thorough contact between the rice grains and water, and improving the uniformity of the washing process.
[0019] By setting the tilt angle of each stirring plate between 5° and 10°, the stirring effect of the stirring plate can be improved, thereby enhancing the disturbance of the water flow and washing away impurities attached to the rice grains, which is beneficial to improving the cleaning effect of the device.
[0020] Furthermore, the arrangement of the first and second arc-shaped protrusions causes the washing tank to vibrate, breaking the adhesion between impurities and rice grains, making it easier for the impurities to be washed away by the water flow. The drive unit rotates the base plate, resulting in a simple structure that is easy to design and implement. The mounting bracket provides a foundation for the drive unit, ensuring its stability. The conical shape of the drainage tank guides the water flow quickly to the second drain outlet, improving drainage efficiency and reducing the residual time of water discharged from the first drain outlets, thus preventing impurity accumulation.
[0021] Furthermore, the sliding direction of the washing tank is constrained by the slider and chute design, ensuring its stability. The first gear, second gear, and motor in the drive unit enhance the stability of the water inlet pipe's rotation. Controlling the motor also allows for adjustments to the pipe's speed, preventing the agitator plates on the inlet pipe from damaging the rice grains. Gaps between the agitator plates and the cover plate allow rice grains conveyed by the agitator plates to pass through and fall back into the washing tank, while also breaking up any clumps of rice grains, improving the washing effect.

[0037] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0038] Example 1
[0039] This embodiment relates to a rice grain washing device that can solve the problems of incomplete cleaning, low cleaning efficiency, and easy breakage of rice grains, thereby reducing the breakage rate of rice grains and improving the cleaning effect and efficiency of the device.
[0040] In terms of overall structure, combined Figures 1 to 7 As shown, the rice washing device of this embodiment includes a cylindrical shell 1, a washing tank 2 slidably disposed on the shell 1, and a water inlet pipe 21 rotatably disposed on the washing tank 2 and extending along the height direction of the shell 1. The washing tank 2 has a feed inlet 22 at the top and a plurality of first drain outlets 23 arranged at intervals along its circumference at the bottom. The shell 1 has a second drain outlet 111 at the bottom that communicates with each of the first drain outlets 23. The water inlet pipe 21 is provided with a plurality of stirring plates 212 arranged at intervals along its circumference for stirring the rice grains, and each stirring plate 212 is inclined.
[0041] At this time, with the above settings, the water inlet pipe 21 and the stirring plates 212 on the water inlet pipe 21 can save manpower. At the same time, the stirring plates 212 are tilted to fully stir the rice grains, preventing the rice grains from accumulating at the bottom of the tank and clogging the first drain outlet 23, thereby improving the cleaning effect of the device. In addition, it can also prevent the rice grains from being damaged by sudden strong pressure, thereby reducing the breakage rate of rice grains and reducing rice waste.
[0042] It is worth mentioning that the relevant structural parts not mentioned in the rice grain washing device of this embodiment can be referred to the various structures of rice grain washing that are well known to those skilled in the art, such as multiple support frames 16 arranged at intervals along the circumference of the housing 1 at the bottom of the housing 1, and handles 28 provided at the top of the washing tank 2, etc.
[0043] In practice, rice grains are put into the feed inlet 22 and water flows into the cleaning tank 2 from the water inlet pipe 21. The water inlet pipe 21 is driven and the stirring plates 212 are rotated to clean the rice grains in the cleaning tank 2. The cleaned water carries the impurities in the rice grains and is discharged from the cleaning tank 2 through the second drain outlet 111 and discharged from the shell 1 through the first drain outlet 23.
[0044] Based on the above overall introduction, in this embodiment, as a preferred implementation, such as Figure 4 As shown, the water inlet pipe 21 is provided with multiple water outlet holes 211 arranged at intervals along its circumference, and each water outlet hole 211 is arranged alternately with each stirring plate 212.
[0045] Here, by setting multiple water outlets 211 on the water inlet pipe 21, water can enter the washing tank 2 from different heights and positions, so that the water can fully contact each grain of rice. At the same time, it can also achieve a balance between saving water and improving washing efficiency. Furthermore, the staggered arrangement of each water outlet 211 and each stirring plate 212 can achieve the purpose of cleaning the stirring plate 212.
[0046] It should be noted that the number of stirring plates 212 in this embodiment can be set to three. Of course, in addition to setting three, the design and adjustment can also be made according to the actual stirring requirements, such as setting two or four. In addition, in the specific structure, eight water outlet holes 211 are provided between the two stirring plates 212, and the number of water outlet holes 211 can also be designed and adjusted according to the actual requirements, such as setting six or seven.
[0047] Furthermore, in this embodiment, as a preferred real-time form, such as Figure 3 and Figure 4 As shown, each stirring plate 212 is provided with multiple through holes 2121, and each through hole 2121 is used to allow water to flow through, so as to reduce the resistance of the corresponding stirring plate 212.
[0048] This design, through the through-hole 2121, reduces the resistance to rotation of each stirring plate 212, thereby reducing equipment energy consumption. It also allows water to flow fully, ensuring that the rice grains are in full contact with the water and improving the uniformity of washing.
[0049] In the specific structure, each stirring plate 212 is provided with six sets of through holes 2121 at intervals along its own height direction, and each set of through holes 2121 has six through holes 2121 arranged at intervals along the length direction of the stirring plate 212. Of course, the number of through holes 2121 can also be designed and adjusted according to actual needs.
[0050] Meanwhile, in this embodiment, as a preferred implementation, such as Figure 4 As shown, the tilt angle α of each stirring plate 212 is between 5° and 10°. This design enhances the agitation effect of the stirring plates 212, thereby increasing the turbulence of the water flow and washing away impurities attached to the rice grains, thus improving the cleaning effect of the device. In a specific structure, the tilt angle α of each stirring plate 212 can be set to 8° to achieve a better stirring effect.
[0051] Furthermore, considering that impurities adhering to rice grains are not easily washed away, in this embodiment, as a preferred implementation, such as... Figure 2 , Figure 5 and Figure 6As shown, a base plate 12 is rotatably mounted on the housing 1. The base plate 12 is provided with a plurality of first arc-shaped protrusions 121 arranged at intervals along its own circumference. The bottom of the cleaning tank 2 is provided with second arc-shaped protrusions 24 corresponding one-to-one with each of the first arc-shaped protrusions 121. Each of the first arc-shaped protrusions 121 and each of the second arc-shaped protrusions 24 contacts each other in sequence to make the cleaning tank 2 vibrate.
[0052] Here, the arrangement of each first arc-shaped protrusion 121 and each second arc-shaped protrusion 24 enables the washing tank 2 to vibrate, thereby breaking the adsorption force between impurities and rice grains, making it easier for the impurities to be washed away by the water flow.
[0053] In the specific structure, each of the first arc-shaped protrusions 121 and each of the second arc-shaped protrusions 24 can be set as 1 / 4 spheres, and each of the first arc-shaped protrusions 121 extends downward and each of the second arc-shaped protrusions 24 extends upward.
[0054] It should be noted that the number of the first arc-shaped protrusions 121 in this embodiment can be set to three. Of course, in addition to setting it to three, it can also be set to two or four, as long as it can ensure the stable vibration of the cleaning tank 2.
[0055] Specifically, in this embodiment, as a preferred implementation, such as Figure 2 As shown, a mounting bracket 13 is provided on the inner wall of the housing 1, and a driving component 14 for driving the base plate 12 to rotate is provided on the mounting bracket 13. Thus, by setting the driving component 14 to drive the base plate 12 to rotate, the structure is simple and easy to design and implement. Furthermore, the setting of the mounting bracket 13 can provide a mounting base for the driving component 14, which helps to ensure the stability of the installation of the driving component 14.
[0056] It is worth mentioning that the driving component 14 in this embodiment can be a driving product well known to those skilled in the art, such as motor 263. In the specific structure, the mounting bracket 13 is provided with a mounting base 131, the driving component 14 is installed in the mounting base 131, and is sealed by the substrate 12.
[0057] In specific implementation, the base plate 12 is driven to rotate by the driving component 14, which in turn drives each of the first arc-shaped protrusions 121 to rotate together, so that the arc-shaped surfaces of each of the first arc-shaped protrusions 121 contact the arc-shaped surfaces of each of the second arc-shaped protrusions 24 in sequence, lifting the cleaning tank 2. Then, after the arc-shaped surfaces of the first arc-shaped protrusions 121 and the arc-shaped surfaces of the second arc-shaped protrusions 24 disengage, the cleaning tank 2 falls down. This cycle is repeated, thereby enabling the cleaning tank 2 to vibrate.
[0058] Furthermore, in this embodiment, as a preferred implementation, such as Figure 2As shown, the bottom of the housing 1 is provided with a conical drainage groove 11, and the second drainage port 111 extends along the height direction of the housing 1 and is arranged at the bottom of the drainage groove 11. Each first drainage port 23 is connected to the second drainage port 111 through the drainage groove 11.
[0059] Here, the drainage channel 11 is set in a cone shape, which can guide the water flow to the second drain outlet 111 quickly, thereby improving the drainage efficiency. At the same time, it can also reduce the residual time of the water flow discharged from each first drain outlet 23, thereby avoiding the accumulation of impurities.
[0060] In practice, the water discharged from the second drain outlet 111 carries impurities from the rice grains, flows through the slope of the drain trough 11 to the first drain outlet 23, and is discharged from the shell 1 through the first drain outlet 23.
[0061] In addition, in this embodiment, as a preferred implementation, such as Figure 5 and Figure 7 As shown, the top of the cleaning tank 2 is provided with a downwardly extending slider 25, which extends circumferentially along the cleaning tank 2. The housing 1 is provided with a sliding groove 15 that matches the slider 25. The cleaning tank 2 slides on the sliding groove 15 via the slider 25. Here, the slider 25 and the sliding groove 15 can constrain the sliding direction of the cleaning tank 2 and ensure the stability of the sliding of the cleaning tank 2.
[0062] In the specific structure, the extension distance of the slider 25 is greater than the sum of the extension distances of the first arc-shaped protrusion 121 and the second arc-shaped protrusion 24, thereby preventing the slider 25 from dislodging from the groove 15 when the first arc-shaped protrusion 121 and the second arc-shaped protrusion 24 come into contact. Furthermore, the slider 25 in this embodiment is annular. Of course, in addition to being annular, it can also be configured as multiple arc-shaped segments arranged at intervals along the circumference of the cleaning groove 2.
[0063] Furthermore, in this embodiment, as a preferred implementation, such as Figure 1 and Figure 2 As shown, the top of the cleaning tank 2 is provided with a cover plate 26, and the cover plate 26 is provided with a drive unit for driving the water inlet pipe 21 to rotate. The drive unit includes a first gear 261 sleeved on the water inlet pipe 21, a second gear 262 meshing with the first gear 261, and a motor 263 for driving the second gear 262 to rotate.
[0064] Here, by setting the first gear 261, the second gear 262 and the motor 263 in the drive unit, the stability of the rotation of the water inlet pipe 21 can be improved. At the same time, the rotation speed of the water inlet pipe 21 can be changed by controlling the motor 263, thereby preventing the stirring plate 212 on the water inlet pipe 21 from damaging the rice grains.
[0065] In specific implementation, the water inlet pipe 21 extends along the height direction of the shell 1 and passes through the cover plate 26. The first gear 261 is sleeved on the water inlet pipe 21. The motor 263 drives the second gear 262 to rotate. The meshing between the second gear 262 and the first gear 261 drives the first gear 261 to rotate, so that the water inlet pipe 21 drives each stirring plate 212 to rotate, and stirs the rice grains in the washing tank 2.
[0066] In addition, in this embodiment, as a preferred implementation, such as Figure 2 and Figure 3 As shown, a gap 27 is provided between each stirring plate 212 and the cover plate 26, and each gap 27 is used for rice grains to pass through. Thus, by providing gaps 27 between each stirring plate 212 and the cover plate 26, the rice grains conveyed by the stirring plate 212 can pass through and fall back into the washing tank 2, while the rice grains that are conveyed and stuck together are dispersed, thereby improving the washing effect.
[0067] In practice, the rice grains move upward along the inclined surfaces of each stirring plate 212 and fall back into the cleaning tank 2 through the corresponding gaps 27. Meanwhile, the rice grains tend to stick together in water. When the rice grains pass through the gaps 27, they are dispersed under the pressure of the gaps 27, which can thoroughly clean the rice grains and improve the cleaning effect of the device.
[0068] In this embodiment, the rice grain washing device is used by placing rice grains in the washing tank 2 and injecting water into the washing tank 2 through the water inlet pipe 21. At this time, the motor 263 drives the second gear 262 to rotate, which in turn drives the first gear 261 to rotate. The rotation of the first gear 261 drives the water inlet pipe 21 to rotate, thereby causing the stirring plates 212 to stir and thoroughly wash the rice grains in the washing tank 2.
[0069] Furthermore, by tilting the stirring plates 212, the rice grains can move upward along the stirring plates 212 and fall back into the cleaning tank 2 through the gap 27. At the same time, the base plate 12 is rotated by the driving component 14, causing the first arc-shaped protrusions 121 and the second arc-shaped protrusions 24 to contact each other in sequence, causing the cleaning tank 2 to vibrate. This breaks the adhesion between the rice grains and impurities, improves the cleaning effect of the device, reduces the breakage rate of rice grains, and helps to improve the cleaning effect and efficiency of the device.
[0070] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
