Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, specifically to a sieve plate for a rice polishing machine. Background Technology

[0002] A rice polishing machine is a piece of equipment used for rice processing. Its main function is to treat the surface of rice. During operation, rice enters the polishing machine and is tumbled by a rotating device inside. Simultaneously, an appropriate amount of water or polishing agent is added. Under the action of friction and the polishing agent, impurities such as bran on the surface of the rice are removed, making the rice surface smoother and shinier. This not only improves the appearance quality of the rice, making it look crystal clear, but also extends its shelf life to some extent. Furthermore, polished rice may have a more delicate texture, making it an indispensable piece of equipment in modern rice processing.

[0003] Inside a rice polishing machine, a traditional sieve plate is responsible for sieving the rice, usually by using a filter plate. However, this traditional method has obvious drawbacks. When changing to a different sized sieve plate, the entire filter plate must be disassembled and a new, compatible filter plate installed. This process is cumbersome, time-consuming, and requires considerable manpower. Furthermore, replacing the filter screen generates a lot of dust, making the process inconvenient. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a rice polishing machine sieve plate with multiple filter positions, multiple filters, quick filter replacement, and a good replacement environment.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is as follows: a rice polishing machine sieve plate, including an outer shell, a plurality of sieve plates are slidably arranged inside the outer shell, placement strips are symmetrically fixed on both sides of the sieve plates, a limiting groove that matches the placement strips is provided on the inner side wall of the outer shell, a baffle is detachably provided on the front side of the outer shell, a dustproof frame is fixedly provided on the top of the outer shell, a dustproof plate is detachably provided inside the dustproof frame, and a vacuum cleaner is provided on the rear side of the outer shell.

[0006] Furthermore, the outer casing has several perforated mounting plates on its sidewalls.

[0007] Furthermore, the limiting grooves are arranged in pairs and opposite to each other, and each limiting groove is provided with a guide strip on its upper and lower walls, and the placement strip is provided with a guide groove on its upper and lower walls that cooperates with the guide strip.

[0008] Furthermore, the limiting groove has oblique protrusions on the upper and lower walls near the sieve plate, the placement strip has oblique grooves on the upper and lower walls that match the oblique protrusions, and the guide strip has a semi-circular cross-section.

[0009] Furthermore, the front sides of the outer shell are symmetrically provided with limiting strips, and the two ends of the baffle are slidably disposed between the limiting strips and the front sidewall of the outer shell. The two ends of the baffle are connected and fixed to the outer shell by screws.

[0010] Furthermore, the dustproof frame has a pull-out opening on the front side, through which the dustproof plate slides. The front side of the dustproof plate has a sealing strip that blocks the pull-out opening, and the two ends of the sealing strip are connected and fixed to the dustproof frame by screws.

[0011] Furthermore, a filter screen is provided at the port of the vacuum cleaner.

[0012] Compared with existing technologies, this invention has the following advantages: The outer casing contains multiple sieve plates and limiting grooves for fixing the sieve plates, enabling multiple sieving processes during rice polishing and achieving excellent sieving results. Each sieve plate is slidably mounted within the outer casing, and its front side is secured by a baffle, facilitating quick replacement and disassembly of the sieve plates without removing the entire outer casing, making it convenient and practical. The removable dustproof plate blocks dust above the sieve plates when removing the baffle for replacement. Combined with a vacuum cleaner, this ensures the cleanliness of the interior of the outer casing, effectively preventing dust from scattering after opening the baffle. This provides a cleaner, dust-free environment for sieve plate replacement and ensures that the rice falls smoothly onto the sieve plates for sieving. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] Combined with appendix Figure 1A rice polishing machine sieve plate includes an outer shell 1. The outer shell 1 has several perforated mounting plates 9 on its side wall, which facilitates the secure installation of the sieve plate 2 on the rice polishing machine, ensuring its positional stability during operation and facilitating the normal operation of the entire polishing process.

[0021] Combined with appendix Figure 4 Appendix Figure 5 The outer casing 1 has several slidable screen plates 2 on its inner side. Placement strips 3 are symmetrically fixed on both sides of the screen plates 2. The inner wall of the outer casing 1 has limiting grooves 4 that cooperate with the placement strips 3. The limiting grooves 4 are arranged in pairs and opposite to each other. The upper and lower walls of the limiting grooves 4 are provided with guide strips 10. The upper and lower walls of the placement strips 3 are provided with guide grooves that cooperate with the guide strips 10. The limiting grooves 4 arranged in pairs and opposite to each other can ensure the stable placement of the screen plates 2. The guide strips 10 and the guide grooves can facilitate the quick and accurate installation of the screen plates 2 inside the outer casing 1. The limiting groove has oblique protrusions 11 on the upper and lower walls near the sieve plate 2. The placement strip 3 has oblique grooves on the upper and lower walls that cooperate with the oblique protrusions 11. The oblique protrusions 11 cooperate with the oblique grooves to further enhance the stability of the sieve plate 2 installation and prevent it from shaking or shifting during operation. At the same time, it can also increase the sealing of the sieve plate 2 installation location and prevent dust or rice from getting stuck in the joint. The guide strip 10 has a semi-circular cross-section, which reduces sliding friction, makes the sieve plate 2 slide more smoothly, and can reduce the wear caused by sliding, further ensuring the sealing of the sieve plate 2 installation location.

[0022] Combined with appendix Figure 1 Appendix Figure 2 The outer shell 1 is detachably provided with a baffle 5 on the front side. The front sides of the outer shell 1 are symmetrically provided with limiting baffles 12. The two ends of the baffle 5 are slidably disposed between the limiting baffles 12 and the front side wall of the outer shell 1. The two ends of the baffle 5 are connected and fixed to the outer shell 1 by screws. The limiting baffles 12 facilitate quick and accurate installation of the baffle 5, thereby facilitating the replacement of the sieve plate 2. The screws can increase the stability of the baffle 5 and prevent dust from being emitted from the baffle 5 during the rice polishing process.

[0023] Combined with appendix Figure 1 Appendix Figure 2 A dustproof frame 6 is fixedly installed on the top of the outer shell 1. A dustproof plate 7 is detachably installed inside the dustproof frame 6. A pull-out opening is provided on the front side of the dustproof frame 6. The dustproof plate 7 is slidably installed through the pull-out opening. A sealing strip 13 is provided on the front side of the dustproof plate 7 to block the pull-out opening. The two ends of the sealing strip 13 are connected and fixed to the dustproof frame 6 by screws. The pull-out opening facilitates the pull-out replacement of the dustproof plate 7. The sealing strip 13 is fixed by screws to ensure the sealing of the pull-out opening, effectively preventing dust from escaping, ensuring the dustproof effect, and facilitating the maintenance of the dustproof plate 7.

[0024] Combined with appendix Figure 3A vacuum cleaner 8 is provided on the rear side of the outer casing 1. A filter screen is provided at the port of the vacuum cleaner 8 to prevent rice particles from being sucked in during the vacuuming process, thus avoiding damage to the vacuum cleaner and waste.

[0025] The specific implementation method of this utility model is as follows: First, the placement strip 3 is slid into the limiting groove inside the outer shell 1 along the guide strip 10. Then, the two ends of the baffle 5 are slidably installed between the limiting baffle 12 and the outer shell 1 and fixed with screws, thereby realizing the stable installation of the sieve plate 2.

[0026] The outer casing 1 is installed on the rice polishing machine using the perforated mounting plate 9. During the rice polishing and sieving process, the dustproof plate 7 is removed, and the sealing strip 13 is installed at the pull-out opening to ensure that the rice can fall smoothly onto the sieve plate 2 for sieving and to prevent dust from escaping.

[0027] When the screen plate 2 needs to be replaced, first remove the sealing strip 13, quickly install the dustproof plate 7 into the dustproof frame 6 through the pull-out port, and then install the sealing strip 13. At this time, the dustproof plate 7 can prevent dust from continuing to fall into the screen plate 2. Turn on the vacuum cleaner 8 to suck out the dust inside the outer shell 1 until the inside of the outer shell 1 is clean. Remove the baffle 5, take out the screen plate 2 from the front and replace it.

[0028] After the sieve plate 2 is replaced, install the baffle 5, remove the dustproof plate 7, and install the sealing strip 13, then it can be put into use again.
