Description

Technical Field

[0001] This utility model relates to the field of rice noodle processing technology, specifically to a rice washing mechanism for rice noodle processing. Background Technology

[0002] Rice is rich in many essential nutrients and is one of the staple foods of the Chinese people, enjoying widespread popularity. With the advancement of technology, rice is gradually being processed into other types of products besides cooked rice, such as rice noodles, rice cakes, and rice parcels. Before further processing, rice needs to be thoroughly washed to remove impurities from the surface, which can further improve the quality of rice by-products.

[0003] A Chinese patent (publication number: CN216757443U) discloses a rice washing device, comprising a water tank, a washing bucket, a stirring assembly, and a cleaning assembly. A drain pipe is fixedly connected to the water tank. The washing bucket is located inside the water tank, with its bottom rotatably connected to the bottom wall of the water tank. Multiple filter holes are formed on the wall of the washing bucket. The stirring assembly is located inside the washing bucket and is used to stir the rice grains inside. The cleaning assembly includes a cleaning roller and a driving component. The cleaning roller is rotatably connected to the water tank, and multiple bristles inserted into the filter holes are fixedly connected to the cleaning roller. The driving component drives the cleaning roller to rotate. During rice washing, when rice grains become stuck in the filter holes, the bristles on the cleaning roller can push the rice grains out of the filter holes, reducing the problem of rice grains clogging the filter holes and thus improving the washing effect of the rice.

[0004] The aforementioned equipment lacks a scrubbing component during the rice washing process. The stirring rod merely rotates the rice without making sufficient contact with it. Impurities on the surface of the rice cannot be completely removed simply by rotating the rice with the stirring rod. In particular, rice bran, dust, and slightly adhered dirt attached to the surface of the rice grains often require the friction generated by scrubbing to be effectively removed.

[0005] To address these issues, we designed a rice washing mechanism for rice noodle processing. Utility Model Content

[0006] The purpose of this invention is to provide a rice washing mechanism for rice noodle processing, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a rice washing mechanism for rice noodle processing, including a washing drum, a stirring frame rotatably connected inside the washing drum, a servo motor connected to the washing drum to drive the stirring frame to rotate, a connecting plate connected to the stirring frame, and two sets of rubbing components arranged on the connecting plate. Each rubbing component includes two rubbing rods rotatably connected inside the washing drum, the two rubbing rods rotating in opposite directions, and multiple rubbing protrusions integrally formed on each rubbing rod. The rubbing protrusions are linearly arrayed and evenly spaced along the axial direction of the rubbing rod, and a driving component for driving the rubbing rods to rotate is provided inside the washing drum.

[0008] Furthermore, the driving component includes a fixed gear ring connected inside the washing drum, a first transmission gear rotatably connected to the connecting plate, the first transmission gear meshing with the fixed gear ring, a second transmission gear meshing with the other side of the first transmission gear, and the first transmission gear and the second transmission gear being coaxially arranged with two scrubbing rods respectively.

[0009] Furthermore, both the second and first transmission gears are connected to a fixing rod, the bottom of which passes through the connecting plate and is connected to a mounting frame. The top of the scrubbing rod is connected to a fixing block, which is inserted into the mounting frame.

[0010] Furthermore, the mounting frame is threaded with limiting bolts to limit the position of the fixing block.

[0011] Furthermore, a feed hopper is connected to one side of the washing drum.

[0012] Furthermore, the outer surface of the scrubbing protrusion is integrally formed with anti-slip particles.

[0013] Furthermore, the two sets of the scrubbing components are arranged symmetrically around the vertical cross-section of the agitator.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. After the servo motor is started, the stirring rack drives the washing components to move in a circular motion, covering the entire washing drum; the transmission gears work together to drive the washing rods to rotate in the opposite direction, and the washing protrusions and anti-slip particles increase friction, creating a dual effect that ensures the washing protrusions make full contact and friction with the rice. Compared to the traditional method that relies solely on stirring, this method can more efficiently remove rice bran, dust, and other dirt, avoiding the problem of insufficient washing in certain areas.

[0015] 2. Depending on the characteristics of the rice grains to be washed, replace with a suitable scrubbing rod. When replacing, simply insert the fixing block at the top of the scrubbing rod into the installation frame, and then tighten the fixing block with the limit bolt to complete the installation. This setting can also prevent the scrubbing rod from loosening and falling off during operation. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a rice washing mechanism for rice noodle processing, including a washing drum (1), a stirring rack (2) rotatably connected inside the washing drum (1), a servo motor (8) for driving the stirring rack (2) to rotate connected to the washing drum (1), a connecting plate (3) connected to the stirring rack (2), and two sets of rubbing components provided on the connecting plate (3). The rubbing components include two rubbing rods (4) rotatably connected inside the washing drum (1), the two rubbing rods (4) rotating in opposite directions, and multiple rubbing protrusions (5) integrally formed on the rubbing rods (4). The rubbing protrusions (5) are distributed in a linear array at equal intervals along the axial direction of the rubbing rods (4). A driving component for driving the rubbing rods (4) to rotate is provided inside the washing drum (1).

[0020] In practice, the servo motor (8) is started, and the servo motor (8) drives the stirring rack (2) to rotate inside the washing drum (1). The stirring rack (2) drives the connecting plate (3) to rotate synchronously, and the connecting plate (3) in turn drives the two sets of washing components to make circular motion around the axis of the stirring rack (2). At the same time, the driving component drives the two washing rods (4) in each washing component to rotate in opposite directions. Since the two sets of washing components are symmetrically arranged, they can achieve a uniform effect on the rice in different areas of the washing drum (1). During the rotation of the washing rod (4), the washing protrusions (5) on its surface move together with the washing rod (4) and come into full contact with the rice. When the washing rod (4) rotates, it will produce a kneading effect on the rice, realizing active washing of the rice instead of simple passive stirring. The multiple washing protrusions (5) integrally formed on the washing rod (4) and distributed at equal intervals in a linear array along the axis increase the contact area between the washing components and the rice. Under the dual action of the reverse rotation of the scrubbing rod (4) and the circular motion of the scrubbing component driven by the stirring rack (2), the scrubbing protrusion (5) can make full and dense contact friction with the surface of the rice. This friction can effectively remove the rice bran, dust and slightly sticky dirt attached to the surface of the rice grains.

[0021] See Figure 1-4 The driving component includes a fixed gear ring (6) connected inside the washing drum (1), a first transmission gear (7) rotatably connected to the connecting plate (3), the first transmission gear (7) meshing with the fixed gear ring (6), and a second transmission gear (9) meshing with the other side of the first transmission gear (7). The first transmission gear (7) and the second transmission gear (9) are respectively coaxially arranged with two scrubbing rods (4).

[0022] In practice, when the servo motor (8) drives the stirring rack (2) to rotate the connecting plate (3), the first transmission gear (7) on the connecting plate (3) will rotate around the axis of the fixed gear ring (6). Since the first transmission gear (7) meshes with the fixed gear ring (6), the fixed gear ring (6) will generate a reaction force on the first transmission gear (7) during the rotation, causing the first transmission gear (7) to rotate. After the first transmission gear (7) rotates, it will drive the second transmission gear (9) meshing with it to rotate. Since the first transmission gear (7) and the second transmission gear (9) are coaxially set with the two scrubbing rods (4) respectively, the rotation of the first transmission gear (7) and the second transmission gear (9) will directly drive the corresponding two scrubbing rods (4) to rotate.

[0023] See Figure 1-4The second transmission gear (9) and the first transmission gear (7) are both connected to a fixing rod (13). The bottom of the fixing rod (13) passes through the connecting plate (3) and is connected to the mounting frame (10). The top of the scrubbing rod (4) is connected to a fixing block (11), which is inserted into the mounting frame (10).

[0024] In practice, when assembling the scrubbing rod (4) and the transmission gear, the fixing block (11) at the top of the scrubbing rod (4) is aligned with the opening of the mounting frame (10), and then the fixing block (11) is inserted into the mounting frame (10) to achieve the initial connection between the scrubbing rod (4) and the first transmission gear (7) or the second transmission gear (9). When the first transmission gear (7) or the second transmission gear (9) rotates, it will drive the mounting frame (10) to rotate through the fixing rod (13), and the mounting frame (10) will then drive the scrubbing rod (4) to rotate through the fixing block (11). This setup allows the scrubbing rod (4) to be replaced according to the size of the rice grains.

[0025] See Figure 1-4 The mounting frame (10) is threaded with a limiting bolt (12) that limits the position of the fixing block (11).

[0026] In practice, after the fixing block (11) is inserted into the mounting frame (10), the limiting bolt (12) is rotated. Since the limiting bolt (12) is threadedly connected to the mounting frame (10), as the limiting bolt (12) rotates, its end will gradually approach the fixing block (11) until it is tightly pressed against the fixing block (11), thereby fixing the fixing block (11) in the mounting frame (10) and preventing the fixing block (11) from loosening or falling off in the mounting frame (10).

[0027] See Figure 1-4 The washing drum (1) is connected to a feed hopper (14) on one side.

[0028] In practice, the operator pours the rice to be washed into the inlet of the feed hopper (14). Under its own gravity, the rice slides down the inner wall of the feed hopper (14) and enters the washing drum (1).

[0029] See Figure 1-4 The outer surface of the scrubbing protrusion (5) is integrally formed with anti-slip particles.

[0030] In practice, when the scrubbing rod (4) drives the scrubbing protrusion (5) to rub against the rice, the anti-slip particles on the outer surface of the scrubbing protrusion (5) will come into close contact with the rice surface. Since the anti-slip particles have a certain degree of roughness, they can increase the friction between the scrubbing protrusion (5) and the rice.

[0031] See Figure 1-4The two sets of scrubbing components are symmetrically arranged with the vertical cross-section of the stirring rack (2) as the center.

[0032] In practice, when the two symmetrical sets of mechanisms rotate with the stirring rack (2), they can simultaneously cover the left and right areas of the washing drum (1). Combined with the reverse rotation of each set of washing rods (4) and the friction of the washing protrusions (5), all the rice in the drum can be thoroughly washed.

[0033] Working principle: According to the characteristics of the rice grains to be washed, select the appropriate washing rod (4), align the fixing block (11) on the top of the rod with the opening of the mounting frame (10) and insert it to complete the connection. Then rotate the limiting bolt (12) on the mounting frame (10) so that its end is tightly against the fixing block (11) to fix the washing rod (4). The operator pours the rice to be washed into the feed hopper (14) on one side of the washing drum (1) and starts the servo motor (8) on the washing drum (1). The servo motor (8) drives the internal stirring frame (2) to rotate. The stirring frame (2) synchronously drives the connecting plate (3) and the two sets of washing components on the connecting plate (3) to make a circular motion around the axis of the stirring frame (2). When the connecting plate (3) rotates, the first transmission gear (7) on it makes a circular motion around the fixed toothed ring (6) inside the washing drum (1). Because the first transmission gear (7) and the fixed toothed ring (6) mesh with each other, the fixed toothed ring (6) generates a reaction force on the first transmission gear (7), causing it to rotate. The first transmission gear (7) then drives the meshing second transmission gear (9) to rotate. Since the first transmission gear (7) and the second transmission gear (9) are respectively coaxially set with the two washing rods (4) of the same washing component, they eventually drive the two washing rods (4) to rotate in opposite directions. When the scrubbing rod (4) rotates, the scrubbing protrusions (5) distributed at equal intervals along the axis on its surface move together. The anti-slip particles on the outer surface of the protrusions increase the friction with the rice. Under the combined action of the scrubbing rod (4) rotating in the opposite direction and the stirring rack (2) driving the scrubbing components to rotate in a circular motion, the scrubbing protrusions (5) make full and dense contact friction with the surface of the rice, effectively removing rice bran, dust and slightly sticky dirt from the surface of the rice grains.
