Description

Technical Field

[0001] This invention relates to the field of rice pulverization technology, specifically to a fine rice pulverization device for processing rice germ powder. Background Technology

[0002] Rice germ powder processing involves extracting and refining the germ portion of rice. The core of this process is to retain the active nutrients in the germ, such as protein, dietary fiber, vitamin E, and oryzanol. Since the germ is easily lost with the rice bran during conventional rice milling, it is necessary to first use specialized separation equipment to effectively separate the germ from the rice bran and broken rice. Then, it undergoes drying and stabilization treatments (such as extrusion puffing or microwave enzyme inactivation) to extend its shelf life. Finally, high-purity germ powder is obtained through fine grinding. This powder is widely used in functional foods, infant complementary foods, and nutritional fortification. A hammer mill is required to grind the rice during processing.

[0003] In existing technology, a hammer mill is used for fine crushing of rice. After removing metal impurities by magnetic separation, the rice or separated germ is evenly fed into the crushing chamber by a vibrating feeder. The high-speed rotating hammer blades break the material through repeated striking, impacting and friction. The crushed powder is discharged through a screen surrounding the bottom or side wall of the crushing chamber. Coarse particles that do not pass through the screen remain in the crushing chamber and continue to be impacted by the hammer blades until they can pass through the screen. The raw materials that pass through the screen are collected and processed centrally.

[0004] However, during use, the germ powder may become blocked in the pneumatic conveying outlet pipe due to moisture, static electricity, or compression. Usually, it is necessary to stop the machine and knock the pipe. It is not possible to use the rotational force of the hammer to knock the outlet pipe, which will cause production interruption, reduce continuous operation efficiency, and cause material accumulation and uncontrolled temperature rise in the crusher due to frequent start-stop. This will accelerate the oxidation and rancidity of heat-sensitive oils in the germ powder. At the same time, uneven knocking force can easily damage the pipe or cause loosening and air leakage at the connection.

[0005] Although it can solve the problem of using hammering power to beat the pipe, it cannot discharge the material according to the crushing rate. Therefore, it is impossible to dynamically match the discharge amount according to the crushing rate, which will make the thickness of the material layer on the screen unstable. Fine powder cannot be discharged in time and will be repeatedly hammered. This not only reduces the crushing efficiency, but also leads to a wider particle size distribution of the finished product and an increased proportion of overly fine powder, which will affect the subsequent processing performance of rice germ powder. Summary of the Invention

[0006] The purpose of this invention is to provide a fine rice pulverizing device for processing rice germ powder, so as to solve the problem of simultaneously using its own hammer rotational power to strike the discharge pipe and performing the pulverizing and discharge operation according to the pulverizing rate.

[0009] Preferably, the discharge control assembly includes a third pulley, a second transmission belt, a fourth pulley, a third rotating rod, a first limiting block, a second pinion gear, a rack, and a second limiting block. The bottom of the first limiting block is fixedly installed on the upper surface of the discharge valve.

The outer surface of the third pulley is drivenly installed on the inner ring of the second transmission belt, and the inside of the second transmission belt is fixedly installed on the outer surface of the second rotating rod. The inside of the second pinion gear is fixedly installed on the outer surface of the third rotating rod. The upper surface of the rack intermittently meshes with the outer surface of the second pinion gear. The lower surface of the second limiting block is fixedly installed on the upper surface of the discharge valve, and the inside of the second limiting block is slidably connected to the outer surface of the rack.

[0010] Preferably, a fixing sleeve is fixedly installed on the outer surface of the rotating rod 2, a receiving frame is fixedly installed on the outer surface of the fixing sleeve, and a striking hammer is fixedly installed at the bottom of the receiving frame.

[0011] Preferably, a rectangular block is fixedly installed on the upper surface of the discharge valve, a connecting spring is fixedly installed on the left side of the rectangular block, and a guide rod is fixedly installed on the left side of the rectangular block.

[0013] Preferably, a control rod is installed inside the discharge valve, and a connecting gear is fixedly installed on the outer surface of the control rod. The outer surface of the connecting gear intermittently meshes with the upper surface of the rack.

[0014] Preferably, a cabinet door is installed on the front of the lower side of the rack, a control panel is installed on the front of the upper side of the rack, and control buttons are installed on the right side of the control panel.

[0015] Preferably, a feed block is fixedly installed on the outer surface of the crushing chamber.

[0016] Preferably, a discharge pipe II is fixedly installed on the lower surface of the connecting plate, one end of the discharge pipe II is fixedly installed with the internal outlet of the discharge valve, and a discharge hopper is fixedly installed on the other end of the discharge pipe II.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention solves the problem in existing technologies where germ powder forms bridges and blockages in the pneumatic conveying outlet pipe due to moisture, static electricity, or compression, requiring machine shutdown and pipe tapping. A drive motor rotates a connecting shaft, which in turn rotates pulley one. Pulley one, via a transmission belt one, drives pulley two, which in turn rotates a rotating rod one and a small gear one. The small gear one intermittently meshes with a large gear, driving the large gear and rotating rod two to rotate intermittently. This, in turn, causes the fixed sleeve, receiving frame, and striking hammer to oscillate periodically, automatically tapping the outlet pipe two. This structure utilizes the hammer's rotational force to tap the outlet pipe without requiring manual tapping, avoiding production interruptions, improving continuous operation efficiency, and preventing material accumulation, uncontrolled temperature rise, and oxidative rancidity of heat-sensitive oils in the germ powder caused by frequent start-stop cycles. It also avoids damage to the pipe or loosening and leakage at connections caused by uneven manual tapping force.

[0018] This invention solves the technical problem of the inability to dynamically match the discharge amount according to the crushing rate in the prior art by setting up a discharge control component. When the rotating rod 2 rotates, it drives the pulley 3 to rotate. The pulley 3 drives the pulley 4 and the rotating rod 3 to rotate through the transmission belt 2. The rotating rod 3 drives the small half gear 2 to intermittently mesh with the rack, pushing the rack to slide within the limit block 2. When the rack slides, it compresses the connecting spring and moves under the guidance of the guide rod. At the same time, the rack intermittently meshes with the connecting gear, driving the connecting gear and the control rod to rotate, thereby realizing the dynamic adjustment of the opening angle of the discharge valve. This structure enables the discharge valve to automatically adjust the discharge rate according to the crushing speed, ensuring that the material layer thickness on the screen remains stable. This allows fine powder to be discharged in a timely manner without being repeatedly hammered, thereby improving crushing efficiency, making the particle size distribution of the finished product more concentrated, reducing the proportion of overly fine powder, improving the subsequent processing performance of rice germ powder, and achieving synergistic optimization of energy saving and quality. The rectangular block provides fixed support for the connecting spring and guide rod, the first limiting block ensures the stable rotation of the rotating rod three, the second limiting block ensures the precise sliding of the rack, the connecting plate fixes the discharge valve to the frame, and the discharge hopper realizes the centralized collection of finished products.

[0021] 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.

[0022] Please see Figure 1 , Figure 5 and Figure 6As shown, the present invention provides a technical solution: a rice fine grinding device for processing rice germ powder, comprising a frame 1, a grinding chamber 6 fixedly installed on the right side of the frame 1, a screen 7 installed inside the grinding chamber 6, a drive motor 5 fixedly installed on the right side inside the frame 1, a connecting shaft 9 fixedly installed on the output shaft of the drive motor 5, the outer surface of the connecting shaft 9 being rotatably mounted to the inner wall of the grinding chamber 6, a discharge pipe 11 fixedly installed on the outer surface of the grinding chamber 6, a discharge valve 12 installed at one end of the discharge pipe 11, a connecting plate 13 fixedly installed at the bottom of the discharge valve 12, the left side of the connecting plate 13 being fixedly installed to the right side of the frame 1, a striking component 10 installed on the outer surface of the connecting shaft 9, a discharge control component 16 for converting rotational power into control force installed at the power output end of the striking component 10, the striking component 10 including a pulley 101, a transmission belt 102, a pulley 103, and a rotating rod 1 104, small half gear 105, large gear 106, and rotating rod 107; the interior of pulley 101 is fixedly installed with the outer surface of connecting shaft 9; the inner ring of transmission belt 102 is driven by the outer surface of pulley 101; the outer surface of pulley 103 is driven by the inner ring of transmission belt 102; one end of rotating rod 104 is rotatably installed with the inner wall of frame 1; the interior of small half gear 105 is fixedly installed with the outer surface of rotating rod 104; the outer surface of large gear 106 intermittently meshes with the outer surface of small half gear 105; one end of rotating rod 107 is rotatably installed with the inner wall of frame 1; the outer surface of rotating rod 107 is fixedly installed with the interior of large gear 106; a fixing sleeve 108 is fixedly installed on the outer surface of rotating rod 107; a receiving frame 109 is fixedly installed on the outer surface of fixing sleeve 108; and a striking hammer 1010 is fixedly installed at the bottom of receiving frame 109.

[0023] Specifically, the power of the drive motor 5 is extracted through the connecting shaft 9. Pulley 101 is fixed to the connecting shaft 9, and the power is smoothly and efficiently transmitted to pulley 103 via the transmission belt 102. This belt drive method has certain buffering and shock absorption properties, effectively reducing impact and vibration during power transmission, ensuring the stability and reliability of power transmission, and preventing damage to subsequent components due to excessive instantaneous impact force. It provides continuous and stable power support for subsequent crushing and discharge control operations. The pulley 103 drives the rotating rod 104 to rotate, which in turn causes the small gear 105 to rotate. The small gear 105 intermittently meshes with the large gear 106, a design that causes the large gear 106 to rotate intermittently. The large gear 106 drives the rotating rod 107 to rotate, and the fixed sleeve 108 rotates together with the rotating rod 107. The receiving frame 109 and the striking hammer 1010 also perform circular motion. The striking hammer 1010 can intermittently strike the screen 7 according to a certain pattern and frequency, effectively preventing the screen 7 from clogging, ensuring that the rice germ powder can pass through the screen 7 smoothly, and improving the crushing efficiency and output quality.

[0024] according to Figure 1 , Figure 7 and Figure 8 As shown, the discharge control assembly 16 includes a third pulley 161, a second transmission belt 162, a fourth pulley 163, a third rotating rod 164, a first limiting block 165, a second pinion 166, a rack 167, and a second limiting block 168. The bottom of the first limiting block 165 is fixedly installed on the upper surface of the discharge valve 12. The outer surface of the third rotating rod 164 is rotatably installed on the inner wall of the first limiting block 165. The inside of the fourth pulley 163 is fixedly installed on the outer surface of the third rotating rod 164. The inner ring of the second transmission belt 162 is driven by the outer surface of the fourth pulley 163. The outer surface of the third pulley 161 is driven by the inner ring of the second transmission belt 162. The inside of the second transmission belt 162 is fixedly installed on the outer surface of the second rotating rod 107. The inside of the second pinion 166 is fixedly installed on the outer surface of the third rotating rod 164. The upper surface of rack 167 intermittently meshes with the outer surface of pinion 166. The lower surface of limit block 168 is fixedly installed with the upper surface of discharge valve 12, and the interior of limit block 168 is slidably connected with the outer surface of rack 167. A rectangular block 169 is fixedly installed on the upper surface of discharge valve 12. A connecting spring 1610 is fixedly installed on the left side of rectangular block 169. A guide rod 1611 is fixedly installed on the left side of rectangular block 169. One end of connecting spring 1610 is fixedly installed with the back of rack 167. One end of guide rod 1611 is fixedly installed with the back of rack 167. A control rod 1612 is installed inside discharge valve 12. A connecting gear 1613 is fixedly installed on the outer surface of control rod 1612. The outer surface of connecting gear 1613 intermittently meshes with the upper surface of rack 167.

[0025] Specifically, pulley three 161 is connected to pulley four 163 via transmission belt two 162, and transmission belt two 162 is also fixed to rotating rod two 107, so that the rotation of rotating rod two 107 in the striking assembly 10 can be accurately transmitted to the discharge control assembly 16. Rotating rod three 164 rotates with pulley four 163, driving pinion two 166 to rotate. Pinion two 166 intermittently meshes with rack 167. This intermittent transmission converts rotation into reciprocating linear motion of rack 167, and then through the intermittent meshing of rack 167 with connecting gear 1613, the rotation of control rod 1612 is precisely controlled, ultimately achieving precise control of the opening and closing of discharge valve 12, ensuring that rice germ powder is discharged at the appropriate time, improving discharge accuracy and product quality stability. The first limiting block 165 provides stable support for the third rotating rod 164, ensuring its smooth rotation; the second limiting block 168 slides and limits the rack 167, so that the rack 167 can only move in a straight line in a specific direction, avoiding deviation or shaking, and ensuring accurate meshing between the second pinion 166 and the rack 167, and between the rack 167 and the connecting gear 1613. This improves the stability and reliability of the entire discharge control assembly 16 transmission, reduces the probability of failure, and extends the service life of the equipment.

[0026] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a cabinet door 2 is installed on the lower front of the frame 1, a control panel 3 is installed on the upper front of the frame 1, a control button 4 is installed on the right side of the control panel 3, a feed block 8 is fixedly installed on the outer surface of the crushing chamber 6, a discharge pipe 14 is fixedly installed on the lower surface of the connecting plate 13, one end of the discharge pipe 14 is fixedly installed to the inner outlet of the discharge valve 12, and a discharge hopper 15 is fixedly installed on the other end of the discharge pipe 14.

[0027] Specifically, the control panel 3 and control buttons 4 located on the front of the upper side of the frame 1 provide operators with an intuitive and convenient operating interface. Operators can view the equipment's operating status and parameters through the control panel 3, and easily start, stop, or adjust operating parameters such as crushing speed and output using the control buttons 4, improving operational convenience and efficiency. Furthermore, the centralized location of the control components on the front of the frame 1 allows operators to easily operate and monitor the equipment during operation, while keeping them away from potentially hazardous areas such as the crushing chamber 6, ensuring operator safety.

[0028] The overall mechanism achieves the following effect: the operator starts the equipment via control button 4 on control panel 3, the drive motor 5 starts running, and drives the connecting shaft 9 to rotate. The connecting shaft 9 drives the hammers inside the crushing chamber 6 to rotate at high speed. At the same time, the connecting shaft 9 transmits power to the pulley 101 of the striking component 10. After removing metal impurities, rice or separated germ is magnetically separated and then evenly fed into the crushing chamber 6 by the vibrating feeder through the feed block 8. The high-speed rotating hammers inside the crushing chamber 6 are driven by the connecting shaft 9 to crush the material through repeated striking, impacting, and friction. The crushed powder passes through the screen 7 and is discharged. The coarse particles that do not pass through the screen remain in the crushing chamber 6 and continue to be impacted by the hammers until they can pass through the screen 7. The raw material that passes through the screen 7 enters the discharge valve 12 through the discharge pipe 11 and is finally collected and discharged from the discharge hopper 15 of the discharge pipe 2 14. When the connecting shaft 9 rotates, it drives the pulley 101 fixed on its outer surface to rotate synchronously. The pulley 101 transmits power to the pulley 103 through the transmission belt 102. Belt pulley 2 103 drives rotating rod 104 to rotate, and rotating rod 104 drives small gear 105 to rotate. Small gear 105 intermittently meshes with large gear 106, driving large gear 106 to rotate intermittently. Large gear 106 drives fixed sleeve 108 to swing through rotating rod 2 107, and fixed sleeve 108 drives receiving frame 109 to swing. The hammer 1010 at the bottom of receiving frame 109 periodically strikes discharge pipe 2 14 to prevent powder from bridging and clogging in the pipe. When rotating rod 2 107 rotates, it drives belt pulley 3 161 fixed on its outer surface to rotate synchronously. Belt pulley 3 161 transmits power to belt pulley 4 163 through transmission belt 2 162. Belt pulley 4 163 drives rotating rod 3 164 to rotate within limit block 165. Rotating rod 3 164 drives pinion 2 166 to rotate. Pinion 2 166 intermittently meshes with rack 167, pushing rack 167 to slide within limit block 2 168. When rack 167 slides, it compresses connecting spring 1610 and moves under the guidance of guide rod 1611. At the same time, rack 167 intermittently meshes with connecting gear 1613, driving connecting gear 1613 to rotate. Connecting gear 1613 drives control rod 1612 to rotate, thereby realizing dynamic adjustment of the opening angle and discharge speed of discharge valve 12. The discharge amount is matched according to the crushing rate. When pinion 2 166 disengages from rack 167, the compressed connecting spring 1610 releases its elastic force, pushing rack 167 to slide back and reset within limit block 2 168. At the same time, guide rod 1611 ensures the accuracy of the reset direction. When the rack 167 slides in the reverse direction, it drives the connecting gear 1613 to rotate in the reverse direction again, which in turn drives the control rod 1612 to rotate in the reverse direction, so that the discharge valve 12 returns to the initial state and waits for the next working cycle.The rectangular block 169 provides fixed support for the connecting spring 1610 and the guide rod 1611. During the entire operation, the operator can maintain and repair the inside of the equipment through the cabinet door 2 on the front of the frame 1, and monitor and adjust the equipment operating parameters through the control panel 3 and control buttons 4.

[0029] The control panel 3 can use a Siemens S7-200SMART series CPUSR20 PLC controller as the core control unit. Its matching control buttons 4 are Schneider XB2BA31C metal buttons and APTAD16-22DS indicator light buttons. The drive motor 5 is a Siemens 1LE0001 series IE4 high-efficiency three-phase asynchronous motor. The discharge valve 12 uses a pneumatic or electric butterfly valve, such as an Emec D971X-16Q electric wafer butterfly valve or an SMC pneumatic ball valve, paired with a valve positioner. For power supply, external three-phase 380V AC power is supplied directly to the drive motor 5 and provides 24VDC control power to the control panel 3 and control buttons 4 via a main circuit breaker and switching power supply (such as a Mean Well SDR-240-24) installed inside the frame 1. Simultaneously, control power is supplied to the actuator of the discharge valve 12 via a relay module.

[0030] When using the machine, ensure that the rotation direction of the drive motor 5 is consistent with the designed meshing phase of the striking component 10. Otherwise, the small half gear 105 and the large gear 106 may jam or fail to transmit intermittently. Regularly check whether the connecting spring 1610 and guide rod 1611 above the discharge valve 12 are contaminated by germ dust and have slow return. Clean the accumulated powder in the slide of the limit block 168. At the same time, observe whether the meshing gap between the rack 167 and the connecting gear 1613 has increased due to wear. If there is obvious back clearance, replace it in time. Third, before starting the machine, ensure that there are no hard objects left in the crushing chamber 6. The feeding speed of the feed block 8 should be gradually adjusted from slow to fast to avoid instantaneous overload that may cause the connecting shaft 9 to twist or the transmission belt 102 to slip and burn. Fourth, after each shift, open the cabinet door 2 to clean the germ dust accumulated inside the frame 1 and check whether the rubber buffer layer of the striking hammer 1010 is worn and exposes the metal substrate. If it is worn, replace it immediately to prevent damage to the discharge pipe 14.

[0031] 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.
