DETAILED DESCRIPTION

[0043] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] See also Figures 1 to 14 In one embodiment, a rice noodle processing grinder includes a grinding base 1, a moving grinding head 2, a filter plate 7, and a driving assembly 4. The moving grinding head 2 is movably mounted on the grinding base 1. The filter plate 7 is mounted on one side of the grinding base 1 and the moving grinding head 2. The driving assembly 4 is used to drive the moving grinding head 2 to rotate, and also includes a moving grinding tooth 100 and a fixed grinding tooth 22.

[0045] The grinding base 1 is a stepped ring, the stepped plane inside the grinding base 1 is inclined toward the axis, and a plurality of fixed grinding teeth 22 are fixedly mounted on the stepped plane inside the grinding base 1;

[0046] The dynamic grinding head 2 is annular, and a plurality of dynamic grinding teeth 100 are fixedly installed at one end of the dynamic grinding head 2 close to the fixed grinding teeth 22. The dynamic grinding teeth 100 cooperate with the fixed grinding teeth 22. The cross-sections of the fixed grinding teeth 22 and the dynamic grinding teeth 100 are trapezoidal, and the spacing between adjacent fixed grinding teeth 22 gradually decreases from the outer side of the grinding base 1 to the inner side of the grinding base 1.

[0047] The filter plate 7 is annular and fixedly connected to the grinding base 1;

[0048] A conical plate 8 is fixedly mounted on the inner wall of the filter plate 7 , and a discharge port 84 is opened at the axis of the conical plate 8 .

[0049] A plurality of feed ports 21 are provided at one end of the movable grinding head 2 , a mounting bracket 11 is fixedly mounted on one end of the grinding base 1 , a feed hopper 12 is detachably mounted on the mounting bracket 11 , and one end of the feed hopper 12 corresponds to the feed port 21 .

[0050] In this embodiment, the stepped plane on the inner side of the grinding base 1 is set to be inclined toward the axis, thereby generating a flow diversion effect, so that the rice grains with smaller particle sizes (after grinding and crushing) can be moved inward during the grinding process, and if the rice grains with slightly larger particle sizes stay on the inner side, they will be crushed by the action of the moving grinding teeth 100;

[0051] By setting the intervals between adjacent fixed grinding teeth 22 and adjacent movable grinding teeth 100 to be gradually changed, the broken rice grains can be guided when grinding the rice grains. During the grinding process, the rice grains will be split into two. The cyclic splitting process is actually the cyclic breaking of the rice grains, so that the particle size of the rice grains is gradually reduced, so that the rice grains can be ground more finely.

[0052] By making the cross-sections of the fixed grinding teeth 22 and the movable grinding teeth 100 trapezoidal, during the rotation of the movable grinding head 2, the fixed grinding teeth 22 and the movable grinding teeth 100 are tightly engaged with each other and rise to the top surface of the trapezoid to fit the movable grinding head 2 and then suddenly drop. The sudden drop process can produce a collision and extrusion effect during the grinding process, and the rice grains are collided and extruded before the contact grinding of the fixed grinding teeth 22 and the movable grinding teeth 100 is performed, so that the grinding effect is better;

[0053] The annular grinding base 1 and the movable grinding head 2 are provided to make the grinding process a cyclic process. When the fineness requirement cannot be met, the grinding head will stay between the fixed grinding teeth 22 and the movable grinding teeth 100 for continuous grinding operation.

[0054] During the grinding process, first, the soaked rice grains are put into the feed hopper 12, and then the dynamic grinding head 2 is driven to rotate by the driving component 4. During the rotation of the dynamic grinding head 2, the feed port 21 corresponds to the feed hopper 12, thereby completing the feeding, and the rice grains fall between the dynamic grinding teeth 100 and the fixed grinding teeth 22 through the feed port 21. During the continuous rotation of the dynamic grinding head 2, the dynamic grinding head 2 shakes up and down, and the up and down shaking is the change in the relative contact position between the dynamic grinding teeth 100 and the fixed grinding teeth 22. After grinding, the rice grains are fused with water to become rice slurry, and then the rice slurry will flow down along the conical plate 8, so that the rice slurry is collected through the discharge port 84.

[0055] Taking into account the requirement for the fineness of rice noodles, a solution route is adopted in which the rice slurry is first ground and then dried to obtain finer rice noodles.

[0056] See also Figure 4 , Fig. 9 , Fig.10 In one embodiment, it further includes a telescopic member 10 , the conical plate 8 is a flexible plate, and the output end of the telescopic member 10 is connected to the discharge port 84 .

[0057] In this embodiment, the output end of the telescopic member 10 is connected to a lifting plate 19. Since the conical plate 8 is a flexible plate, the shape of the flexible plate can be changed under the action of the telescopic member 10. The conical plate 8 in the figure is funnel-shaped, which is the default initial state. The telescopic member 10 is started, and the telescopic member 10 pushes the flexible plate, and the flexible plate changes from a funnel shape to an inverted funnel shape, thereby adjusting the original drainage from outside to inside to drainage from inside to outside.

[0058] During the grinding process, the soaked rice grains are put into the feed hopper 12, and then the dynamic grinding head 2 is driven to rotate by the driving component 4. During the rotation of the dynamic grinding head 2, the feed port 21 corresponds to the feed hopper 12, so as to complete the feeding. The rice grains fall between the dynamic grinding teeth 100 and the fixed grinding teeth 22 through the feed port 21. During the continuous rotation of the dynamic grinding head 2, the dynamic grinding head 2 shakes up and down, and the up and down shaking is the change of the relative contact position between the dynamic grinding teeth 100 and the fixed grinding teeth 22. After grinding, the rice grains are fused with water to become rice slurry, and then the rice slurry will flow down along the conical plate 8, that is, the rice slurry can be retained by the conical plate 8. After a period of time, the telescopic member 10 is started to change the conical plate 8. It is in the shape of an inverted funnel, so that the rice slurry can flow in the reverse direction, from the conical plate 8 to between the fixed grinding teeth 22 and the movable grinding teeth 100, so as to realize the reverse flushing of the filter plate 7, and can avoid the clogging of rice grains at the filter screen and the jamming of rice grains at the mesh of the filter plate 7. Secondly, the reverse flow of rice slurry can reorganize the position of rice grains between the fixed grinding teeth 22 and the movable grinding teeth 100, that is, the rice grains originally located on the inside are flushed to the outside, so as to continue the grinding operation. Thirdly, the flushing of rice slurry allows the rice powder ground between the fixed grinding teeth 22 and the movable grinding teeth 100 to be dissolved in the rice slurry, so that it is taken away when the conical plate 8 is deformed next time, so that less water can dissolve more rice powder, that is, the concentration of rice slurry is increased, thereby improving the efficiency of subsequent rice slurry drying.

[0059] See also Fig. 9 In one embodiment, a hinged plate 82 is rotatably mounted on the discharge port 84 , and a sealing strip 83 is mounted on one end of the hinged plate 82 .

[0060] In this embodiment, two hinged plates 82 are rotatably mounted at the discharge port 84 , and the hinged plates 82 are semicircular in shape.

[0061] By providing a hinged plate 82, sealing of the discharge port 84 can be achieved. When discharge is required, the telescopic member 10 is moved away from the hinged plate 82, and the hinged plate 82 is flipped under the action of the gravity of the rice slurry carried thereon, thereby completing the discharge. When discharge is not required, the hinged plate 82 is pressed tightly by the telescopic member 10, thereby sealing of the discharge port 84 can be achieved.

[0062] See also Fig.11 , Fig.12 , Fig.13 In one embodiment, it also includes a filter cloth 9, a filter cloth 9 is installed on the inner side of the filter plate 7, one end of the filter cloth 9 is connected to the connecting plate 15, and the other end of the filter cloth 9 is located at the discharge port 84. Both ends of the filter cloth 9 are open, and a lifting rod 20 is installed at one end of the connecting plate 15 close to the discharge port 84.

[0063] In this embodiment, during the grinding process, when the hinged plate 82 is opened, one end of the filter cloth 9 is open at the discharge port 84 and prolapses outside the discharge port 84. First, the hinged plate 82 is closed by the telescopic member 10, and the open end of the filter cloth 9 is clamped by the sealing strip 83 on the hinged plate 82, so that one end of the filter cloth 9 is sealed and clamped. Then, the soaked rice grains are put into the feed hopper 12, and then the dynamic grinding head 2 is driven to rotate by the driving assembly 4. The dynamic grinding head 2 During the rotation, the feed port 21 corresponds to the feed hopper 12, so that the feeding is completed, and the rice grains fall into the space between the movable grinding teeth 100 and the fixed grinding teeth 22 through the feed port 21. During the continuous rotation of the movable grinding head 2, the movable grinding head 2 shakes up and down, and the up and down shaking is the change of the relative contact position between the movable grinding teeth 100 and the fixed grinding teeth 22. After grinding, the rice grains are fused with water to become rice slurry, and then the rice slurry flows down along the conical plate 8 and flows into the The filter cloth 9 is used to store the rice slurry. After a period of time, the telescopic member 10 is activated to change the conical plate 8 into an inverted funnel shape. At this time, under the action of the telescopic member 10, one end of the filter cloth 9 is lifted above the hinged plate 82 under the action of the lifting rod 20, that is, the filter cloth 9 forms an independent retention space. Under the action of gravity, the water in the rice slurry in the filter cloth 9 is filtered out and flows into the fixed grinding teeth 22 along the conical plate 8. The filtered water is In this way, the filter plate 7 can be reversely flushed, and the clogging of rice grains in the filter screen and the jamming of rice grains in the mesh of the filter plate 7 can be avoided. Then, the telescopic member 10 is started. Under the action of the telescopic member 10, the conical plate 8 becomes funnel-shaped. When the telescopic member 10 continues to extend and retract until the hinged plate 82 is away from the telescopic member 10, the hinged plate 82 is opened, and one end of the filter cloth 9 becomes open again. At this time, the rice slurry (higher concentration) at the center of the filter cloth 9 can be discharged.

[0064] See also Figure 1 , Figure 2 In one embodiment, it also includes a transmission component 6, a positioning shaft 18 is installed at one end of the connecting plate 15 away from the discharge port 84, a cover plate 3 is installed on the filter plate 7, a rotating column 5 is movably installed on the cover plate 3, the rotating column 5 is transmission-connected with the positioning shaft 18, the transmission component 6 is connected to the rotating column 5, and the transmission component 6 is used to drive the rotating column 5 to rotate forward and reverse and the positioning shaft 18 to move back and forth.

[0065] In this embodiment, the forward and reverse rotation of the rotating column 5 can be realized by providing a transmission assembly 6, and the forward and reverse rotation can be converted into reciprocating movement by transmission connection between the rotating column 5 and the positioning shaft 18.

[0066] See also Fig.13 , Fig.14 In one embodiment, the transmission connection method of the rotating column 5 and the positioning shaft 18 can adopt the following scheme: a threaded ring 17 is fixedly installed on the connecting plate 15, and a center limiting hole 52 and an annular groove 53 are opened on the rotating column 5. The center limiting hole 52 corresponds to the positioning shaft 18, the threaded ring 17 is located in the annular groove 53, and the rotating column 5 is threadedly connected with the threaded ring 17.

[0067] In this embodiment, the outer side surface of the threaded collar 17 is provided with an external thread, and the annular recessed groove 53 is provided with an internal thread corresponding to the threaded collar 17 .

[0068] When the rotating column 5 rotates forward, the positioning shaft 18 is located in the central limiting hole 52, which can limit the position of the connecting plate 15. The telescopic member 10 is started, and the conical plate 8 is presented as an inverted funnel shape through the telescopic member 10. At this time, the threaded collar 17 just contacts the annular groove 53. When the rotating column 5 continues to rotate, the threaded collar 17 is threadedly connected with the annular groove 53, so that the connecting plate 15 and the threaded collar 17 rise until the top of the external thread reaches the top of the internal thread. At this time, there is no relative movement between the threaded collar 17 and the rotating column 5. Then, the rotating column 5 will drive the threaded collar 17 to rotate while rotating. When the connecting plate 15 and the threaded collar 17 rise, one end of the filter cloth 9 also rises at the same time, that is, the overall height of the filter cloth 9 increases, so that the rice slurry can be concentrated at the bottom. When the rotating column 5 rotates and drives the threaded collar 17 to rotate, since the filter cloth 9 is clamped and fixed at one end, one end of the filter cloth 9 is gradually "tightened" during the rotation process, and the filter cloth 9 can be twisted by torsional force, so that the rice slurry can be squeezed. At the same time, under the action of rotation, the rice slurry is subjected to the action of centrifugal force, so that the moisture is thrown out.

[0069] See also Figures 11 to 13 In one embodiment, a plurality of second arc-shaped flexible rods 14 and a first arc-shaped flexible rod 13 are movably installed at one end of the filter cloth 9, the first arc-shaped flexible rod 13 is slidably connected to the second arc-shaped flexible rod 14, an elastic telescopic tube 16 is installed between the second arc-shaped flexible rod 14 and the connecting plate 15, a plurality of limit rods 51 are installed on the rotating column 5, and the limit rods 51 are located on the outside of the second arc-shaped flexible rod 14 and the first arc-shaped flexible rod 13, and an annular groove 81 corresponding to the first arc-shaped flexible rod 13 and the second arc-shaped flexible rod 14 is opened on the conical plate 8.

[0070] In this embodiment, the second arc-shaped flexible rod 14 is provided with a through hole corresponding to the first arc-shaped flexible rod 13 , and the first arc-shaped flexible rods 13 at both ends of the second arc-shaped flexible rod 14 are located in the through hole and are slidably connected to the second arc-shaped flexible rod 14 .

[0071] During the grinding process, when the hinged plate 82 is opened, one end of the filter cloth 9 is open at the discharge port 84 and prolapses outside the discharge port 84. First, the hinged plate 82 is closed by the telescopic member 10, and the open end of the filter cloth 9 is clamped by the sealing strip 83 on the hinged plate 82, so as to achieve the sealing and clamping of one end of the filter cloth 9, and then the soaked rice grains are put into the feed hopper 12, and then the dynamic grinding head 2 is driven to rotate by the driving assembly 4. After grinding, the rice grains are fused with water to become rice slurry, and then the rice slurry will flow down along the conical plate 8 and flow into the filter cloth 9, that is, the rice slurry is achieved through the filter cloth 9. After a period of time, the telescopic member 10 is started to change the conical plate 8 into an inverted funnel shape. During the change, the first arc-shaped flexible rod 13 or the second arc-shaped flexible rod 14 is close to the limit rod 51, that is, the first arc-shaped flexible rod 13 will be retracted into the second arc-shaped flexible rod 14, so that the upper end of the filter cloth 9 can be retracted. After the change is completed, the threaded ring 17 just contacts the annular groove 53. When the rotating column 5 continues to rotate, the threaded ring 17 is threadedly connected to the annular groove 53, so that the connecting plate 15 and the threaded ring 17 rise until the outer When the top of the thread reaches the top of the internal thread, there is no relative movement between the threaded collar 17 and the rotating column 5. Then, the rotating column 5 rotates and drives the threaded collar 17 to rotate. When the connecting plate 15 and the threaded collar 17 rise, one end of the filter cloth 9 also rises at the same time, that is, the overall height of the filter cloth 9 increases, and the top of the filter cloth 9 is gathered, so that the rice slurry is concentrated at the bottom. When the rotating column 5 rotates and drives the threaded collar 17 to rotate, since the filter cloth 9 is clamped and fixed at one end, one end of the filter cloth 9 is gradually "tightened" during the rotation process, and the filter cloth 9 can be twisted by the torsional force, thereby The rice slurry can be squeezed, and under the action of rotation, the rice slurry is subjected to the centrifugal force, so that the water is thrown out, and then the rotating column 5 is driven to reverse through the transmission component 6, so that the threaded ring 17 gradually decreases. When the threaded ring 17 is separated from the rotating column 5, under the gravity of the rice noodle block, the conical plate 8 changes from an inverted funnel shape to a funnel shape, and then the telescopic member 10 continues to retract, so that the hinged plate 82 rotates. After the hinged plate 82 rotates, one end of the filter cloth 9 is in a prolapsed state, so that it can be "released" under the gravity of the rice noodle block above, so that the dehydrated rice noodle block can be discharged.

[0078] The transmission assembly 6 can also use the reciprocating movement of the rack to realize the positive and negative rotation of the gear, which is not limited to the above solution.

[0079] Working principle of the present invention: During the grinding process, when the hinged plate 82 is opened, one end of the filter cloth 9 is open at the discharge port 84 and prolapses outside the discharge port 84. First, the hinged plate 82 is closed by the telescopic member 10, and the open end of the filter cloth 9 is clamped by the sealing strip 83 on the hinged plate 82, so as to achieve the sealing and clamping of one end of the filter cloth 9, put the soaked rice grains into the feed hopper 12, and then drive the dynamic grinding head 2 to rotate through the driving component 4. During the rotation of the dynamic grinding head 2, the feed port 21 corresponds to the feed hopper 12, so as to complete the feeding, and the rice grains fall into the dynamic grinding teeth 100 and the fixed grinding teeth 22 through the feed port 21. After grinding, the rice grains are fused with water to become rice slurry, and then the rice slurry will flow down along the conical plate 8 and into the filter cloth 9, that is, the rice slurry is retained by the filter cloth 9. After a period of time, the telescopic member 10 is started to change the conical plate 8 into an inverted funnel shape. During the change, the first arc-shaped flexible rod 13 or the second arc-shaped flexible rod 14 is close to the limiting rod 51, that is, the first arc-shaped flexible rod 13 will be retracted into the second arc-shaped flexible rod 14, so that the upper end of the filter cloth 9 can be retracted. After the change is completed, the threaded ring 17 just contacts the annular sink groove 53. When the rotating column 5 continues to rotate, the threaded ring 1 7 is threadedly connected with the annular sink groove 53, so that the connecting plate 15 and the threaded collar 17 rise until the top of the external thread reaches the top of the internal thread. At this time, there is no relative movement between the threaded collar 17 and the rotating column 5, and then the rotating column 5 will drive the threaded collar 17 to rotate while rotating. When the connecting plate 15 and the threaded collar 17 rise, one end of the filter cloth 9 also rises at the same time, that is, the overall height of the filter cloth 9 increases, and the top of the filter cloth 9 is in a gathered shape, so that the rice slurry is concentrated at the bottom. When the rotating column 5 rotates and drives the threaded collar 17 to rotate, since the filter cloth 9 is clamped and fixed at one end, one end of the filter cloth 9 is gradually "raised" during the rotation process. The "force" can twist the filter cloth 9 through torsional force, and then squeeze the rice slurry. At the same time, under the action of rotation, the rice slurry is subjected to the centrifugal force, so that the water is thrown out, and then the rotating column 5 is driven to reverse through the transmission component 6, so that the threaded collar 17 gradually decreases. When the threaded collar 17 is separated from the rotating column 5, under the gravity of the rice noodle block, the conical plate 8 changes from an inverted funnel shape to a funnel shape, and then the telescopic member 10 continues to retract, so that the hinged plate 82 rotates. After the hinged plate 82 rotates, one end of the filter cloth 9 is in a prolapsed state, so that it can achieve "release of force" under the gravity of the rice noodle block above, so that the dehydrated rice noodle block can be discharged.
