Description

Technical Field

[0001] This invention relates to the field of nutritional rice processing technology, specifically to a mixed grain nutritional rice processing device based on an energy-saving electric motor. Background Technology

[0002] Mixed grain rice is made from brown rice, oats, buckwheat, quinoa, and black rice, which are ground, mixed, and recombined to create a combination of various nutrients.

[0003] Current methods for grinding mixed grains into nutritional rice mainly employ a single-stage rigid grinding structure driven by a motor. In actual operation, due to the varying hardness of the grains, grinding different grains with a fixed-specification grinding structure can result in insufficient grinding of hard grains and stringy adhesion of soft grains due to their toughness. To address this issue, existing technologies primarily use a combination of hammering and airflow to grind the grains. During the grinding process, lightweight, qualified powder, heavy, large particles, and uncrushed lumps accumulate mixed at the bottom of the grinding chamber. Qualified powder does not detach from the grinding area in time, and as the heavy, large particles continue to be repeatedly hammered, they become encased and obscured by the powder, unable to effectively contact the hammering surface. This prolonged retention at the bottom of the chamber prevents thorough grinding, leading to an imbalance where fine powder is over-ground and coarse powder remains intact. This reduces the overall uniformity of the ground material and restricts the processing quality of the finished mixed grain nutritional rice product. Summary of the Invention

[0004] The purpose of this invention is to provide a mixed grain nutrient rice processing device based on an energy-saving electric motor, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mixed grain nutrient rice processing device based on an energy-saving electric motor, comprising: The cylinder body and the inner cylinder disposed within the inner cavity of the cylinder body, wherein the top of the cylinder body is provided with multiple feed inlets communicating with the inner cavity of the inner cylinder, and further includes: The crushing mechanism includes a drive assembly installed at the top of the feed inlet, a pressing assembly connected to the drive assembly, and a cover provided on the inner wall of the inner cylinder. Multiple spring members are distributed circumferentially on the top of the cover, and a pressing member is connected to the top of each spring member. The outer wall of the cover is sequentially provided with a first guide member arranged in a circumferential pattern and a first protruding strip arranged in an alternating pattern along the central axis of the cover. The inclination angle of the first guide member is smaller than that of the first protruding strip. The inner wall of the inner cylinder is sequentially provided with a second guide member arranged in a circumferential pattern and a second protruding strip arranged in an alternating pattern along the central axis of the inner cylinder. The inclination angle of the second guide member is smaller than that of the second protruding strip. The first guide member and the second guide member are engaged with each other. The pneumatic mechanism includes channels distributed inside the inner cylinder sidewall, one end of the channel being connected to the bottom of the inner cylinder and the other end of the channel being located at the top of the inner cylinder, and the outer walls of the extruder and the cover are respectively provided with sealing components for fitting the inner wall of the inner cylinder; The lifting mechanism includes a pressure plate connected to the bottom of the cover, and several shovels are evenly distributed along the circumference of the bottom of the pressure plate.

[0006] Preferably, the drive assembly includes an energy-saving motor, the output end of which is provided with a screw, the screw passing through the top of the cylinder, the outer wall of the screw being threaded with a connector, both ends of which are fixedly connected to the inner wall of the extruder, and the bottom end of the screw is provided with a crushing component.

[0007] Preferably, a ring is fixedly installed on the outer wall of the extrusion member, and the top end of each spring member is connected to the bottom of the ring.

[0008] Preferably, the sealing assembly includes a first sealing ring and a second sealing ring, wherein the first sealing ring is fitted onto the outer wall of the extruder, and the second sealing ring is fitted onto the outer wall of the cover.

[0009] Preferably, the bottom end of the channel is provided with an air inlet, which is connected to the bottom inner side of the inner cylinder, and the top end of the channel is provided with an exhaust port, which is connected to the top inner side of the inner cylinder.

[0010] Preferably, the bottom of the pressure plate has several slots along the circumferential direction, and the shovel plate is movably installed inside the slots.

[0011] Preferably, one end of the shovel plate is provided with a shaft, and the two ends of the shaft are connected to the inside of the groove.

[0012] Preferably, a plurality of cutting blades are evenly distributed on the inner side of the shovel plate, and the cutting blades are distributed below the groove opening.

[0013] Preferably, the inner wall of the inner cylinder has a plurality of guide strips evenly distributed along the circumferential direction, and the outer wall of the extrusion piece and the outer wall of the ring are both provided with grooves, the grooves being connected to the guide strips.

[0014] Preferably, the bottom of the extrusion member is provided with a valve body, and the bottom of the valve body is connected to the inner side of the bottom of the cover.

[0015] Compared with the prior art, the beneficial effects of the present invention are: In this technology, the engagement of the first and second guide members generates an oblique torque, causing the cover and inner cylinder to rub against each other. Combined with the larger angle and the densely arranged first and second convex strips from top to bottom, the residence time of the grains in the upper crushing zone is extended. This achieves simultaneous extrusion, rubbing, and cutting of grains with varying hardness, thoroughly crushing hard grains and preventing soft grains from sticking together. This avoids the defects of traditional single-stage rigid crushing, such as over-crushing of fine powder and retention of coarse powder, improving the uniformity and processing quality of the finished grain rice. Simultaneously, during the downward pressing process, the first and second sealing rings construct a sealed crushing chamber, autonomously generating a high-pressure airflow through the downward extrusion action. The air inlet and outlet form a self-circulating air duct. During the downward pressing process, the light and qualified fine powder is automatically conveyed upward to the top of the crushing zone, separating the fine powder from the heavy and uncrushed lumps of grain at the bottom in real time. This prevents the fine powder from covering the coarse particles and obscuring the crushing working surface, reducing ineffective repeated crushing actions, improving crushing efficiency, and further shortening the working time of the energy-saving motor. In addition, the hinged opening and closing shovel plate with a cutter at the bottom of the pressure plate retracts and scoops up the lumps of material at the bottom during the downward pressing stage and assists in cutting. During the upward stage, the shovel plate slowly opens and throws the material to the second convex strip on the side wall, continuously turning over the accumulated grains at the bottom of the cavity, preventing material from accumulating in dead corners, and allowing the grains to repeatedly enter the crushing zone for processing, ensuring that the material is fully crushed.

Detailed Implementation

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

[0019] To address the problem of lightweight, qualified powder, heavy, large particles, and uncrushed lumps accumulating at the bottom of the grinding chamber during existing grinding processes, where qualified powder fails to detach from the grinding area in time, and heavy, large particles become trapped and obscured by powder as they are repeatedly hammered, preventing them from effectively contacting the hammering surface and resulting in prolonged stagnation at the bottom of the chamber and insufficient grinding, thus leading to over-grinding of fine powder and under-grinding of coarse powder, a mixed grain nutrient rice processing device based on an energy-saving electric motor is proposed. (Refer to...) Figures 1-5 and Figure 8 As shown: The system includes a cylindrical body 100 and an inner cylinder 211 disposed within the cavity of the cylindrical body 100. The top of the cylindrical body 100 is provided with multiple feed inlets 101 communicating with the inner cavity of the inner cylinder 211. It also includes: The crushing mechanism 200 includes a drive assembly installed on the top of the feed inlet 101, a pressing assembly connected to the drive assembly, and a cover 208 disposed on the inner wall of the inner cylinder 211. A plurality of spring members 207 are distributed along the circumferential direction on the top of the cover 208. A pressing member 205 is connected to the top of the spring members 207. The outer wall of the cover 208 is provided with a first guide member 209 arranged in a ring and a first protrusion 210 arranged in an alternating manner along the central axis of the cover 208. The inclination angle of the first guide member 209 is smaller than that of the first protrusion 210. The inner wall of the inner cylinder 211 is provided with a second guide member 212 arranged in a ring and a second protrusion 213 arranged in an alternating manner along the central axis of the inner cylinder 211. The inclination angle of the second guide member 212 is smaller than that of the second protrusion 213. The first guide member 209 and the second guide member 212 are engaged and connected. The pneumatic mechanism 300 includes a channel 303 distributed inside the side wall of the inner cylinder 211. One end of the channel 303 is connected to the bottom of the inner cylinder 211, and the other end of the channel 303 is located at the top of the inner cylinder 211. The outer walls of the extruder 205 and the cover 208 are respectively provided with sealing components for fitting the inner wall of the inner cylinder 211. The lifting mechanism 400 includes a pressure plate 401 connected to the bottom of the cover 208, and a number of shovels 404 are evenly distributed along the circumference at the bottom of the pressure plate 401.

[0020] Specifically, different grain raw materials are stored inside the feed inlet 101. When it is necessary to process nutritious rice, the grain raw materials are released into the extruder 205 installed inside the inner cylinder 211 by opening the valve at the bottom of the feed inlet 101 for crushing.

[0021] The pressing assembly is connected to the drive assembly for transmission. The drive assembly moves the pressing component 205 downwards. Simultaneously, a controller, such as a controllable logic controller, sends a signal to open the valve body 214 at the bottom of the pressing component 205. The valve body 214 can be an electrically controlled valve or a solenoid valve, allowing the grains inside the pressing component 205 to enter the inner cylinder 211. During the pressing process, the pressing component 205 crushes and grinds the grains inside the inner cylinder 211. A cover 208 is movably fitted onto the outer side of the pressing component 205. A first guide 209 distributed on the outer wall of the cover 208 engages with a second guide 212 distributed on the inner wall of the inner cylinder 211, and the guides are inclined. During the pressing process, the second guide... 212 exerts an oblique thrust on the first guide member 209, causing the cover 208 to twist slightly. The inner cylinder 211 remains fixed relative to the cover 208. A first protrusion 210 and a second protrusion 213 are respectively provided between the outer wall of the cover 208 and the inner wall of the inner cylinder 211. During the downward twisting process, the first protrusion 210 and the second protrusion 213 can crush and pulverize the grains. The first protrusion 210 and the second protrusion 213 are distributed sequentially from top to bottom, from dense to sparse, forming a dense area and a sparse area. This increases the residence time of the grains in the upper dense area, achieving multiple crushing processes. The second guide member 212 and the second protrusion 213 are fixed on the inner wall surface of the inner cylinder 211. Figure 7 and Figure 8 As shown, the first convex strip 210 and the second convex strip 213, through their different spacing distribution, can separate grains of different particle sizes. By using a single drive component to combine extrusion crushing and torsional crushing, the crushing efficiency can be improved while reducing the number of drive units, thereby reducing the number of times the energy-saving motor 201 operates and reducing the energy consumption of the energy-saving motor 201. The energy-saving motor 201 is a YE5 series model, which can improve the energy-saving effect while ensuring operating efficiency.

[0022] The outer walls of the extruder 205 and the cover 208 are respectively provided with a first sealing ring 301 and a second sealing ring 302. The first sealing ring 301 and the second sealing ring 302 are made of food-grade hydrogenated nitrile rubber. During the pressing and crushing process, the extruder 205 and the cover 208 simultaneously generate air pressure on the inside of the inner cylinder 211 through the pressure generated by pushing. Several channels 303 are opened on the side wall of the inner cylinder 211. Lightweight powder structure is input from the bottom end to the top end of the channel 303 through the air pressure and input into the inside of the extruder 205. The pressure generated during pressing forms a continuous action, which can separate the powder from the uncrushed grains, so that the uncrushed grains are exposed for further crushing. By reducing the powder coating on the grains, useless pressing and crushing actions can be effectively reduced, so that the grains can be crushed evenly, thereby improving the crushing efficiency and reducing the running time of the energy-saving motor 201.

[0023] Several shovels 404 are distributed and installed at the bottom of the cover 208 via the pressure plate 401. During the pressing process, the shovels 404 are inserted into the grains and powder at a 45° downward angle in a petal shape. When the shovels 404 come into contact with the bottom of the inner cylinder 211, the pressure generated by the squeezing closes the shovels 404. After completing one pressing and crushing action, as the pressing component is lifted, the shovels 404 are driven to rise synchronously. During the rising process, the shovels 404 slowly open, which can throw the grains to the second protrusions 213 distributed on the inner wall of the inner cylinder 211. The second protrusions 213 are distributed with multiple protrusions, which can slow down the falling speed of the grains, making it easier to crush the grains when pressing down again, thereby further improving the crushing efficiency.

[0024] Supplementary explanation, combined with Figure 10 and Figure 11 R1 is the rotation direction of the energy-saving motor 201 when the pressing component is pressed down, corresponding to the pressing action achieved by L1. When the pressing reaches the bottom of the inner cylinder 211, the first guide 209 and the second guide 212 engage to form an oblique thrust, causing the cover 208 to twist and perform further crushing action. This causes the shovel plate 404 to gradually close and shovel up the grains and powders at the bottom. When the pressing and crushing process is completed and the material rises, the energy-saving motor 201 rotates to state R2, driving the pressing component 205 to rise. At the same time, the spring component 207 pushes the cover 208 to rotate and reset. The shovel plate 404 slowly unfolds and throws the grains onto the second protrusion 213 for the next crushing process.

[0025] like Figures 2-8As shown, the drive assembly includes an energy-saving motor 201. The output end of the energy-saving motor 201 is provided with a screw 202, which passes through the top of the cylinder 100. The outer wall of the screw 202 is threaded with a connector 204. Both ends of the connector 204 are fixedly connected to the inner wall of the extruder 205. A crusher 203 is provided at the bottom end of the screw 202. A ring 206 is fixedly installed on the outer wall of the extruder 205. The top ends of the springs 207 are all connected to the bottom of the ring 206. Several guide strips 215 are evenly distributed along the circumferential direction on the inner wall of the inner cylinder 211. Grooves are provided on the outer wall of the extruder 205 and the outer wall of the ring 206. The grooves are connected to the guide strips 215. A valve body 214 is provided at the bottom of the extruder 205. The bottom of the valve body 214 is connected to the inner side of the bottom of the cover 208.

[0026] Specifically, a screw 202 is located at the output end of an energy-saving motor 201. A controller sends a signal to the energy-saving motor 201 to drive the screw 202 to rotate in both directions, thereby achieving rotational lifting. A connector 204 is connected to the outer wall of the screw 202, and its two ends are fixedly connected to the inner wall of the extruder 205, enabling the extruder 205 to be adjusted in height. A crusher 203 is located at the bottom end of the screw 202, which performs pre-crushing during the first feeding process and also provides mixing. A ring 206 provides mounting support for the spring 207. A guide bar 215 is located on the inner wall of the inner cylinder 211 and engages with the outer walls of the extruder 205 and the cover 208, providing guidance during lifting. A valve 214, in conjunction with the controller, controls the opening and closing of the valve, facilitating the sealing and release of grain materials.

[0027] like Figure 3 , Figure 5 and Figure 7 As shown, the sealing assembly includes a first sealing ring 301 and a second sealing ring 302. The first sealing ring 301 is sleeved on the outer wall of the extrusion 205, and the second sealing ring 302 is sleeved on the outer wall of the cover 208. The bottom end of the channel 303 is provided with an air inlet 304, which is connected to the bottom inner side of the inner cylinder 211. The top end of the channel 303 is provided with an exhaust port 305, which is connected to the top inner side of the inner cylinder 211.

[0028] Specifically, the first sealing ring 301 and the second sealing ring 302 are respectively provided on the outer walls of the extruder 205 and the cover 208, providing a sealing effect and thus improving the sealing performance during use. Powder can be input into the interior of the channel 303 through the air inlet 304 and output back into the interior of the extruder 205 through the exhaust port 305. After the crushing process is completed, the valve body 214 and the bottom valve can be opened to discharge the processed powder.

[0029] like Figure 8 and Figure 9 As shown, the bottom of the pressure plate 401 has several slots 402 along the circumferential direction. The shovel plate 404 is movably installed inside the slots 402. One end of the shovel plate 404 is provided with a shaft 403. The two ends of the shaft 403 are connected to the inside of the slots 402. Several cutters 405 are evenly distributed on the inside of the shovel plate 404. The cutters 405 are distributed below the slots 402.

[0030] Specifically, the slot 402 provides space for installation and movement. The shaft 403 movably mounts the shovel plate 404 inside the slot 402 and has a damping effect, providing a slow unfolding effect and reducing the material drop speed. Furthermore, the damping effect of the shaft 403 is formed by a torsion spring or friction damper sleeved on the shaft 403. The cutter 405 provides an auxiliary function of crushing and chopping after shoveling, while also increasing the support strength of the shovel plate 404 to ensure the crushing effect.

[0031] Combining the above features and effects, the complete working principle of this technology is as follows: Multiple feed inlets 101 store different types of grain raw materials. During processing, the bottom valve of the feed inlet 101 is opened to release the grain into the inner cavity of the extruder 205 at the top of the inner cylinder 211. An energy-saving motor 201 serves as the power source for the drive assembly. The forward rotation of the energy-saving motor 201 drives the screw 202 to rotate along the R1 direction. The screw 202 drives the connecting piece 204 downward through threaded engagement. The connecting piece 204 synchronously pulls the extruder 205 vertically downward along the guide strip 215 on the inner wall of the inner cylinder 211. The device simultaneously opens the bottom valve body 214 of the extruder 205, allowing the grains inside the extruder 205 to fall into the crushing chamber formed by the cover 208 and the inner cylinder 211. The crushing component 203 at the bottom of the screw 202 moves down synchronously to pre-crush the falling grains. During the downward pressing process of the extruder 205, the ring body 206 compresses the spring component 207, pushing the cover 208 downward synchronously. The first guide component 209, which is inclined on the outer wall of the cover 208, engages and slides with the second guide component 212, which is inclined on the inner wall of the inner cylinder 211. The difference in their inclination angles creates an oblique component force, forcing the cover 208 to produce... A slight circumferential twist occurs, and the first convex strips 210, distributed around the outer wall of the cover 208 and decreasing in density from top to bottom, rub against the second convex strips 213 on the inner wall of the inner cylinder 211, performing a dual crushing action of compression and rubbing on the grains. The inclination angles of the first guide member 209 and the second guide member 212 are smaller than those of the first convex strips 210 and the second convex strips 213, respectively. The larger inclination angle of the convex strips can prolong the residence time of the grains in the upper crushing zone, achieving multi-level repeated crushing and adapting to the graded crushing of grains with different particle sizes; the first sealing ring 301 on the outer wall of the extrusion member 205, and the cover... The second sealing ring 302 on the outer wall of 208 is tightly fitted with the inner wall of the inner cylinder 211 to form a sealed cavity. The extruder 205 and the cover 208 descend to compress the air in the cavity. The high-pressure airflow flows into the channel 303 through the air inlet 304 at the bottom of the channel 303 on the side wall of the inner cylinder 211. The airflow carries the light qualified powder in the cavity upward along the channel 303 and flows back to the upper space of the extruder 205 through the exhaust port 305 at the top of the channel 303. This separates the qualified fine powder from the heavy grain lumps at the bottom that are not completely crushed, reducing the situation where fine powder wraps around coarse particles, resulting in insufficient crushing.The bottom pressure plate 401 of the cover 208 moves downwards, and the shovel 404, hinged to the shaft 403 inside the slot 402, is tilted at 45° and plunges into the material pile at the bottom of the cavity. After the pressure plate 401 touches the bottom, the bottom reaction force pushes the shovel 404 to retract and close inwards around the shaft 403. The inner cutter 405 of the shovel 404 simultaneously cuts and crushes the clumps of grain. After a single pressing and crushing process is completed, the energy-saving motor 201 rotates in the opposite direction along R2, and the screw 202 lifts the connecting piece 204, driving the extruder 205 upwards. The spring in the compressed state... 207 The elastic rebound pulls the cover 208 to reverse twist and reset, and the pressure plate 401 rises synchronously. After the bottom is no longer constrained by pressure, the damped shaft 403 drives the shovel 404 to slowly unfold outward. The shovel 404 carries the uncrushed grains from the bottom and throws them to the surface of the second convex strip 213. The protrusions on the surface of the second convex strip 213 slow down the falling speed of the grains. The material remains in the crushing zone to wait for the next round of downward crushing cycle. After all the grains are crushed to the standard, the valve body 214 and the discharge valve at the bottom of the cylinder are opened, and the finished nutritional rice powder is discharged uniformly.

[0032] It should be noted that, in practical application, this solution can also employ a method for grinding and processing mixed grain rice, including the following steps: S1: The drive assembly drives the extruder 205 to move downward, and the grains enter the crushing chamber between the cover 208 and the inner cylinder 211 from the bottom of the extruder 205. The crushing chamber is the space between the inner cylinder 211 and the cover 208. S2: During the pressing process of the extruder 205, the first guide 209 and the second guide 212 mesh to generate oblique torque, which drives the cover 208 to rotate circumferentially relative to the inner cylinder 211. The first convex strip 210 and the second convex strip 213 perform dual crushing of the grain by extrusion and rubbing. S3: During the pressing process of the extruder 205, the sealing component and the inner wall of the inner cylinder 211 form a sealed cavity. The pressing action compresses the air in the cavity of the inner cylinder 211 to generate a high-pressure airflow. The high-pressure airflow carries the light qualified powder through the channel 303 from the bottom to the top of the inner cylinder 211, so that the qualified powder is separated from the uncrushed lumps. S4: When the extrusion piece 205 is pressed down to the bottom, the shovel plate 404 is retracted by the reaction force and shovels up the material accumulated at the bottom. S5: When the extruder 205 rises, the shovel plate 404 slowly unfolds, throwing the material onto the second protrusion 213, so that the material stays in the crushing zone and waits for the next crushing cycle. The crushing zone is the area inside the crushing chamber. S6: Repeat steps S2-S5 until all grains are ground to the required standard. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
