Description

Technical Field

[0001] This invention relates to the field of rice grinding technology, specifically a vertical shaft rice grinding machine. Background Technology

[0002] The vertical shaft rice mill is a specialized pulping equipment that adopts a vertical spindle structure. The core grinding unit consists of paired moving and stationary grinding discs. The motor is directly connected to the vertical shaft, which drives the moving grinding discs to rotate at high speed. The processed rice falls into the grinding chamber from the top feed hopper by gravity. Water is continuously added during the grinding process. The fineness of the rice pulp can be flexibly controlled by adjusting the handwheel to control the gap between the moving and stationary grinding discs. The ground pulp and large impurities can flow out from two outlets respectively.

[0003] Operators typically pour large quantities of rice into the conical hopper at once, making it difficult to continuously monitor the feeding process. This is because the conical hopper's neck is a transitional area where the feeding path abruptly narrows. After soaking, starch precipitates from the surface of the rice, increasing its adhesion and the internal friction and binding force between the rice grains. The material at the edge of the neck experiences stronger frictional resistance from the cone wall, resulting in a significantly slower falling speed compared to the central area. The material will squeeze and accumulate here. When the lateral support force formed by the accumulation exceeds the weight of the material itself, it will form an arched material arch, completely blocking the feeding path. This creates a gap in the feeding process, leading to the problem of empty grinding on both the lower and upper grinding discs. Summary of the Invention

The water conveying mechanism includes a fixed ring fixedly connected to the outer wall of the cone bucket, a water conveying pipe fixedly connected to the outer wall of the fixed ring, a number of water outlets opened on the outer wall of the water conveying pipe, a water outlet pipe fixedly connected to the inner wall of the number of water outlets, and a baffle fixedly connected to the outer wall of the number of water outlets. Pressure holding mechanism, which is installed on the inner wall of the outlet; A balancing mechanism is installed on the outer wall of the water supply pipe. The system has five water outlets arranged in a circular array. The water supply pipe is connected to the water outlets, and the water outlets are connected to the water supply pipe. The baffle bends towards the cone. After the water flows out from the water supply pipe through the water outlet pipe, it hits the baffle, causing the water to flow down the cone wall. After the operator installs the lower grinding disc, they install the upper grinding disc and then pour the processed rice into the cone. Water is continuously added during the processing. The motor below the lower grinding disc is started, which drives the lower grinding disc to rotate. The rice and water fall into the gap between the lower and upper grinding discs for grinding. After centrifugal filtration, the residue and rice slurry are discharged separately.

[0005] Preferably, the water conveying mechanism further includes: The fixing component is installed on the outer wall of the water supply pipe; The water outlet assembly is installed on the outer wall of the water outlet pipe on the side away from the water outlet. The operator adds water to the water pipe through a fixed component.

[0006] Preferably, the pressure-holding mechanism includes: Limiting components are installed on the inner wall of the outlet pipe; The active component is installed on the outer wall of the limit component; Different water flow sizes can control the opening degree of the movable components, and the limiting components restrict the movement of the movable components.

[0007] Preferably, the balancing mechanism includes: Overflow assembly, which is installed on the outer wall of the water supply pipe; The regulating component is installed on the inner wall of the outlet pipe; The overflow component reminds the operator of the water flow level, and the adjustment component adjusts the water flow rate.

[0008] Preferably, the fixing component includes an inlet pipe that is connected to the outer wall of the water supply pipe; Water flows from the inlet pipe into the inside of the delivery pipe.

[0009] Preferably, the water outlet assembly includes a tapered tube fixedly connected to the side of the water outlet pipe away from the water outlet; The conical tube is inverted conical in shape, and the inner diameter of the side of the conical tube away from the outlet pipe is smaller than that of the outlet pipe.

[0010] Preferably, the limiting component includes a fixing bracket fixedly connected to the inner wall of the water outlet pipe, a limiting plate fixedly connected to the inner wall of the water outlet pipe, and a locking plate fixedly connected to the inner wall of the water outlet pipe. Among them, the fixing bracket is closer to the water outlet than the limiting plate; The limiting plate and the locking plate are set in a mirror image, and the fixing bracket is in a non-central position, with the fixing bracket installed closer to the tapered tube.

[0011] Preferably, the movable component includes a spring fixedly connected to the outer wall of the fixed frame, and a movable plate is fixedly connected to the side of the spring away from the fixed frame; The spring is located between the limiting plate and the fixing frame; The spring is initially in a stretched state, and the tilt angles of the two sides of the movable plate are the same as those of the limiting plate and the locking plate. Under the action of the spring, the movable plate is tightly attached to the limiting plate.

[0012] Preferably, the overflow assembly includes several balance pipes connected to the outer wall of the water supply pipe, each balance pipe having an overflow port on its outer wall, and each balance pipe having a sliding column slidably connected to its outer wall. The balance pipe is located on the other side of the water outlet and is connected to the water supply pipe. There are five balance tubes in total, arranged in a circular array. Preferably, the adjusting assembly includes an adjusting rod threadedly connected to the outer wall of the outlet pipe, and a movable plug is fixedly connected to the side of the adjusting rod near the tapered pipe; Among them, the taper of the side of the movable plug facing the outlet of the tapered tube is the same as the taper of the inner wall of the tapered tube; The tapered tube is made of rigid silicone.

[0013] The present invention has the following beneficial effects: (1) The present invention utilizes the fact that when water flows into the water delivery pipe from the inlet pipe, the water flow impacts the baffle and is affected by the baffle, impacting the inner wall of the cone bucket. Since the outlet pipe is arranged in a circular array, during the water addition process, the circumferential water inlet penetrates evenly from all sides to the center of the material layer. The entire surface of the rice grains in the constricted section is covered by a water film, and the starch adhesion force and internal friction force between the particles decrease simultaneously, making it difficult to form an arched material arch. Through the application of the above components, the problem of a large amount of material being added into the cone bucket at the same time, resulting in an arched material arch at the constricted section of the cone bucket, which affects the normal material feeding is effectively alleviated.

[0014] (2) The present invention addresses the problem of water flowing from the inlet pipe to the outlet pipe in the above-mentioned device. When a small amount of water comes into contact with the movable plate, the water pressure is insufficient to push the movable plate. At this time, the water entering from the inlet pipe will move to a more distant area. When the water inside the water supply pipe reaches a certain level, the water will overflow the spring, thereby increasing the water pressure on the side of the movable plate near the fixed frame, thus pushing the movable plate towards the locking plate. The elastic potential energy of the spring increases, and the movable plate will disengage from the limiting plate. Thus, the water can flow out from the gap between the movable plate and the outlet pipe and flow out from the direction of the conical pipe. The liquid level in the outlet pipe is at the same level, and all five outlet pipes can output water. Through the application of the above-mentioned components, the problem of water flowing from the inlet pipe into the water supply pipe, the water flow in the outlet pipe near the inlet pipe being larger, and the water flow in the outlet pipe far from the inlet pipe being smaller or even non-existent is effectively prevented.

[0015] (3) This invention utilizes the feature of the above-mentioned equipment where water flow drives the movable plate to move. When the operator adds less water, the water flow is difficult to reach the bend of the balance pipe, thus making it difficult to lift the sliding column. It can be judged that the water flow is too small. When the water flow is too large, the water outlet pipe is blocked. At this time, the water flow will flow towards the balance pipe and lift the sliding column to move upward. When the sliding column passes the overflow port, the water flow will flow out from the overflow port. Thus, it can be judged that the water inlet is too large. Thus, the operator can judge whether the water addition is within the normal range by the degree of lifting of the sliding column and whether water is coming out of the overflow port. Through the application of the above components, the problem of repeated adjustment of water addition by the operator, resulting in excessive waste of rice paste and extended operation time is effectively alleviated.

[0016] (4) The present invention addresses the problem of water flowing out of the conical tube in the above-mentioned equipment. Different operators have different operating habits when adding water, so a fixed size of the outlet diameter is difficult to adapt to different operating needs. When it is necessary to adjust the water flow, the operator can adjust the depth of the adjustment rod by rotating the adjustment rod. Since the curvature of the movable plug cone surface is equal to that of the conical tube, the water flow can be controlled by controlling the distance between the movable plug and the conical tube. Therefore, the water flow can be kept stable and controllable in the face of different inlet flow rates. The application of the above components effectively improves the applicability of the device.

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.

[0021] Example 1, please refer to Figures 1-5 This invention relates to a vertical shaft rice milling machine, comprising a machine base 13, a lower grinding disc 14 rotatably connected to the inner wall of the machine base 13, an upper grinding disc 15 fixedly connected to the top outer wall of the machine base 13, and a conical hopper 16 fixedly connected to the top outer wall of the upper grinding disc 15, and further comprising: Water conveying mechanism 1 is installed on the outer wall of cone 16.

After the operator installs the lower grinding disc 14, they install the upper grinding disc 15 and then pour the processed rice into the cone 16. Water is continuously added during the processing.

The rice and water fall into the gap between the lower grinding disc 14 and the upper grinding disc 15 for grinding. After centrifugal filtration, the residue and rice slurry are separated and discharged.

[0025] Example 2, please refer to Figures 2-8 The present invention is a vertical shaft rice milling machine. Based on Example 1, the fixing component 11 includes a water inlet pipe 113 that is connected to the outer wall of the water supply pipe 112. Water flows from the inlet pipe 113 into the inside of the delivery pipe 112.

[0026] The water outlet assembly 12 includes a tapered tube 124 fixedly connected to the side of the water outlet pipe 122 away from the water outlet 121; Among them, the tapered tube 124 is inverted tapered, and the inner diameter of the side of the tapered tube 124 away from the water outlet pipe 122 is smaller than that of the water outlet pipe 122.

[0027] The limiting component 21 includes a fixing bracket 211 fixedly connected to the inner wall of the water outlet pipe 122, a limiting plate 212 fixedly connected to the inner wall of the water outlet pipe 122, and a locking plate 213 fixedly connected to the inner wall of the water outlet pipe 122. Among them, the fixing bracket 211 is closer to the water outlet 121 than the limiting plate 212; The limiting plate 212 and the locking plate 213 are set in a mirror image, and the fixing bracket 211 is in a non-central position. The fixing bracket 211 is installed closer to the tapered tube 124.

[0028] The movable component 22 includes a spring 221 fixedly connected to the outer wall of the fixed frame 211, and a movable plate 222 is fixedly connected to the side of the spring 221 away from the fixed frame 211. Among them, spring 221 is located between limiting plate 212 and fixing frame 211; The spring 221 is initially in a stretched state. The tilt angles of the two sides of the movable plate 222 are the same as those of the limiting plate 212 and the locking plate 213. Under the action of the spring 221, the movable plate 222 is in close contact with the limiting plate 212.

[0029] The overflow assembly 31 includes several balance pipes 311 connected to the outer wall of the water supply pipe 112. Each balance pipe 311 has an overflow port 312 on its outer wall and a sliding column 313 slidably connected to its outer wall. Among them, the balance pipe 311 is located on the other side of the water outlet 121, and the balance pipe 311 is connected to the water supply pipe 112; There are five balance tubes 311 in total, arranged in a circular array. The adjusting assembly 32 includes an adjusting rod 321 threadedly connected to the outer wall of the outlet pipe 122, and a movable plug 322 is fixedly connected to the side of the adjusting rod 321 near the tapered pipe 124; Among them, the taper of the side of the movable plug 322 facing the outlet of the tapered tube is the same as the taper of the inner wall of the tapered tube 124; The tapered tube 124 is made of rigid silicone.

[0030] One specific application of this embodiment is as follows: When in use, the operator installs the lower grinding disc 14 and then the upper grinding disc 15. The processed rice is then poured into the cone hopper 16. Water is continuously added during the processing. The motor below the lower grinding disc 14 is started to drive the lower grinding disc 14 to rotate. The rice and water fall into the gap between the lower grinding disc 14 and the upper grinding disc 15 for grinding. After centrifugal filtration, the residue and rice slurry are discharged separately.

[0031] Operators typically pour large quantities of rice into the cone hopper 16 at once, making it difficult to continuously monitor the feeding process. This is because the constriction of the cone hopper 16 is a transitional area where the feeding passage abruptly narrows. After soaking, starch precipitates from the surface of the rice, increasing its adhesiveness and the internal friction and binding force between the rice grains. The material at the edge of the constriction experiences stronger frictional resistance from the cone wall, resulting in a significantly slower falling speed compared to the central area. The material tends to press and accumulate here, and when the lateral support force generated by this accumulation exceeds the weight of the material itself... This will form an arched material arch, completely blocking the material feeding passage, creating a gap in the material feeding process, and causing the lower grinding disc 14 and upper grinding disc 15 to grind without material. When water flows from the inlet pipe 113 into the water supply pipe 112, there is a certain amount of water inside the water supply pipe 112, and the water will flow through the outlet 121 to the outlet pipe 122. At this time, the water flows out from the conical pipe 124 and impacts the side of the baffle 123 near the outlet 121. Because the baffle 123 is bent towards the inner wall of the conical bucket... The curved arc shape of the cone hopper 16 means that when the water flow impacts the baffle 123, it is affected by the baffle 123 and impacts the inner wall of the cone hopper 16. Since the water outlet pipe 122 is arranged in a circumferential array, during the water addition process, the circumferential water inlet penetrates evenly from all sides to the center of the material layer. The surface of the rice grains in the entire constricted section is covered by a water film, and the starch adhesion and internal friction between the grains decrease simultaneously, making it difficult to form an arched material arch. At this time, when the grinding is nearing the end, the amount of rice is greatly reduced, and some rice will stick to the inner wall of the cone hopper 16. Conventional operation requires adding a large amount of water, which will lead to the problem of the slurry becoming too thin at the end of the grinding process. By adding water circumferentially at the same time, it is difficult for rice to stick to the inner wall of the cone hopper 16, eliminating the final water addition step and alleviating the problem of the slurry becoming thin due to adding a large amount of water at the end of the grinding process. Through the application of the above components, the problem of a large amount of material being added into the cone hopper 16 at the same time, resulting in an arched material arch at the constricted section of the cone hopper 16, which affects the normal material feeding is effectively alleviated.

[0032] The aforementioned equipment addresses the issue of water entering through the inlet pipe 113 and exiting through the outlet pipe 122. When water enters through the inlet pipe 113, the water flow from the outlet pipe 122 closer to the inlet pipe 113 is larger, while the flow from the outlet pipe 122 further away from the inlet pipe 113 is smaller or nonexistent. This makes it difficult to achieve circumferential water intake and alleviate the arched material arching problem. When water enters through the water pipe 112, the water flow contacts the fixed frame 211 and then the movable plate 222. Due to the spring 221 being biased towards the tapered tube 124, when a small amount of water contacts the movable plate 222, the water pressure is insufficient to push it. The water entering through the inlet pipe 113 then moves further away. Once a certain amount of water is added to the water pipe 112... At this time, the water will overflow the spring 221, thereby increasing the water pressure on the side of the movable plate 222 near the fixed frame 211, thus pushing the movable plate 222 to move towards the locking plate 213. The elastic potential energy of the spring 221 increases, and the movable plate 222 will disengage from the limiting plate 212. Thus, the water can flow out from the gap between the movable plate 222 and the outlet pipe 122, and flow out from the direction of the conical pipe 124. The liquid level in the outlet pipe 122 is at the same level. At this time, all five outlet pipes 122 can output water. Through the application of the above components, the problem of water flowing from the inlet pipe 113 into the delivery pipe 112, the water flow in the outlet pipe 122 near the inlet pipe 113 being larger, and the water flow in the outlet pipe 122 far from the inlet pipe 113 being smaller or even non-existent is effectively prevented.

[0033] Utilizing the characteristic of the aforementioned equipment where water flow propels the movable plate 222, it is difficult for operators to control the water flow during the water addition process. After starting the machine, operators need to adjust the water inlet according to the viscosity of the output slurry. Inexperienced operators need to make repeated adjustments, resulting in excessive waste of unsuitable rice slurry. When the operator adds too little water, the water will first accumulate at the spring 221. When the water pressure reaches a certain level, it will push the movable plate 222 to release some water. However, because the water inlet is less than the water outlet, the water flow is difficult to reach the bend of the balance pipe 311, thus making it difficult to lift the sliding column 313. This indicates that the water flow is too small. When the water flow is too large, the water pressure in front of the movable plate 222 will quickly reach the threshold, thereby pushing the movable plate 222. 2. Move towards the clamping plate 213. Since the inflow is greater than the outflow, the water pressure will quickly push the movable plate 222 to press against the clamping plate 213, thereby blocking the outlet pipe 122. This makes it difficult for water to flow out of the conical pipe 124. After the water outflow from the outlet pipe 122 is blocked, the water will flow towards the balance pipe 311 and lift the sliding column 313 upward. When the sliding column 313 passes the overflow port 312, the water will flow out from the overflow port 312. This allows the operator to determine whether the water volume is within the normal range by observing the degree to which the sliding column 313 is lifted and whether water is flowing out of the overflow port 312. The application of the above components effectively alleviates the problem of repeated adjustments to the water volume by the operator, which leads to excessive waste of rice paste and extended operation time.

[0034] Regarding the issue of water flowing out of the conical tube 124 using the above-mentioned equipment, different operators have different operating habits when adding water. Therefore, a fixed-size outlet diameter is difficult to adapt to different operating needs. When it is necessary to adjust the water flow, the operator can rotate the adjusting rod 321 to adjust the screw depth of the adjusting rod 321. Since the curvature of the conical surface of the movable plug 322 is equal to that of the conical tube 124, the water flow can be controlled by controlling the distance between the movable plug 322 and the conical tube 124. Therefore, the water flow can be kept stable and controllable for different inlet water flow rates. Through the application of the above components, the applicability of the device is effectively improved.
