Description

Technical Field

[0001] This invention relates to the field of rutin raw material feeding technology, specifically a special controllable feeding and conveying device for rutin production raw materials. Background Technology

[0002] Rutin is an important raw material for the production of pharmaceuticals and health products. Sophora japonica buds, as its core natural raw material, are often transported vertically upwards using bucket elevators in industrial production. Sophora japonica buds are relatively light and have small particles, which easily generate fine powder during transportation. They also have a certain degree of adhesion and poor overall flowability, which are significantly different from the transportation characteristics of conventional granular materials, placing higher demands on the structural adaptability of the conveying equipment.

[0003] Conventional bucket elevators rely on the buckets reaching the top and then ejecting material under centrifugal force and gravity. However, when used for conveying Sophora japonica buds, incomplete ejection is a common problem. Some buds adhere to the inner wall of the buckets and cannot be discharged smoothly, while some material falls back down the casing to the bottom of the equipment, resulting in significant material backflow and leakage. Repeated lifting and conveying of this backflow material reduces the equipment's effective conveying efficiency and increases operating energy consumption. Furthermore, the repeated collisions and falls of the buds cause them to break down, leading to a continuous increase in fine powder content, further exacerbating material adhesion and retention, creating a vicious cycle. This also damages the integrity of the raw material, affecting the stability and efficiency of subsequent rutin extraction.

[0004] During transport, Sophora japonica buds continuously rub and collide with the hopper and machine casing, generating static electricity. Conventional equipment lacks dedicated static electricity conduction and discharge structures, causing static electricity to accumulate on the material and the equipment's inner walls. This accumulation not only exacerbates the adhesion of fine Sophora japonica bud powder to the equipment's inner walls and hopper, further worsening material return and retention problems, but also poses a safety hazard due to electrostatic discharge. As a medicinal raw material, Sophora japonica bud production requires strict environmental safety and cleanliness standards; the dust accumulation caused by static electricity makes it difficult to meet the specifications and quality requirements of pharmaceutical production.

[0005] In existing improvement solutions, mechanical scrapers easily come into hard contact with the hopper, causing the locust flowers to break and damaging the hopper, resulting in poor practicality. Simple air-assisted unloading often uses direct blowing, making it difficult to precisely control the airflow direction and velocity. This easily creates turbulence, causing fine powder to fly around and resulting in raw material loss. Furthermore, it cannot effectively coordinate with the material's projection trajectory and flow path. The simple flow guiding structures equipped in some devices are mostly fixed, unable to be linked with the hopper's operation and airflow conveying. The flow guiding path is prone to creating dead zones where material accumulates, making cleaning difficult, and it cannot simultaneously achieve material guidance and electrostatic discharge.

[0006] Currently, the feeding and conveying equipment for Sophora japonica flowers is difficult to balance in terms of sufficient unloading, return material control, static electricity elimination, and raw material integrity protection. It suffers from insufficient operational stability and low raw material utilization, failing to meet the requirements of efficient, stable, safe, and clean conveying in the continuous industrial production of rutin. Therefore, it is necessary to design a special feeding and conveying device adapted to the characteristics of Sophora japonica flowers, optimize the structural design, and ensure the smooth and stable production process.

[0007] Therefore, we propose a special controllable feeding and conveying device for rutin production raw materials. Summary of the Invention

[0008] One of the technical problems this application aims to solve is that current sophora japonica feeding and conveying equipment cannot simultaneously ensure sufficient unloading, control of material return, elimination of static electricity, and protection of raw material integrity. It also suffers from insufficient operational stability and low raw material utilization, failing to meet the requirements of efficient, stable, safe, and clean conveying processes for continuous industrial production of rutin.

[0009] To solve the above-mentioned technical problems, this application provides a special controllable feeding and conveying device for rutin production raw materials, including a housing. The lower right and upper left parts of the housing are respectively provided with a feed inlet and a discharge outlet. A grounding wire is provided on the outside of the housing. A driven wheel and a driving wheel are provided inside the housing. A chain is provided on the driven wheel and the driving wheel. Several hoppers are provided on the chain. An air pump is provided on the right side of the housing. The air pump is connected to the air outlet of the housing through an air supply pipe. A guide plate is provided on the inner wall of the housing near the top.

[0010] In some embodiments, the air pump is mounted on the support leg, which is located on the right side of the machine housing at the same horizontal level as the discharge port. The air inlet is located on the right side wall of the machine housing at the air pipe connection point. A motor is mounted next to the air pump, and the motor is connected to the drive wheel via a connector.

[0011] In some embodiments, the discharge port is oriented obliquely from right to left and the cross-section decreases from large to small. The guide plate includes an ascending section, a horizontal section, and a descending section, which are connected by arcs in sequence. The starting point of the ascending section is parallel to the center line of the arc-shaped bottom of the hopper at the top of the drive wheel, and the air outlet is parallel to the center line of the arc-shaped bottom of the hopper at the top of the drive wheel.

[0012] In some embodiments, the horizontal section is parallel to the top surface of the casing, the descending section is parallel to the direction of the discharge port, the guide groove formed between the guide plates facilitates the limiting and guiding of the locust flowers, one end of the grounding wire is connected to the guide plate, and the other end is connected to the ground.

[0013] In some embodiments, a second guide plate is provided at the connection between the discharge port and the inner wall of the casing. A left limiting member is provided on the left side of the second guide plate, a limiting edge is provided on the right side of the second guide plate, and a connecting hole is provided at the end of the second guide plate. A connecting shaft is provided in the connecting hole, and a torsion spring is provided on the connecting shaft.

[0014] In some embodiments, a magnet is built into the lower side of the guide plate 2, and the hopper is composed of an arc-shaped bottom, a connecting side plate, and a counter side plate. The connecting side plate is connected to the chain, and a magnet 2 is provided on the outer side of the connecting side plate.

[0015] In some embodiments, the magnetic properties of opposite faces of magnet one and magnet two are opposite.

[0016] In some embodiments, a narrow strip-shaped hole is uniformly provided on the arc-shaped bottom, and an arc edge one and an arc edge two are provided on both sides of the narrow strip-shaped hole.

[0017] In some embodiments, rotating bars are provided on the narrow strip hole, the first arc edge, and the second arc edge.

[0018] In some embodiments, the rotating bar is located at one end of the arc edge and is rotatably mounted on both sides of the arc-shaped bottom plate via a rotating shaft.

[0019] The present invention has at least the following beneficial effects: 1. A continuous guide channel structure is formed by a guide plate located near the top of the inner wall of the machine casing. The rising, horizontal, and descending sections of the guide plate are connected by arcs in sequence. This effectively collects and limits the incomplete throwing of material from the hopper, material sticking to the hopper and falling back, as well as fine powder and fragments of Sophora japonica that slide down the machine casing. This prevents material from scattering into dead corners of the machine casing or falling directly back to the bottom of the cylinder, structurally reducing material return and leakage, ensuring the regularity of the material conveying path, and improving the overall feeding and conveying efficiency. The discharge port adopts a diagonal design from right to left with a cross-section that gradually decreases in size. This, combined with the guiding effect of the guide channel, further guides the material to discharge smoothly, reducing the probability of material accumulation and blockage at the discharge position and ensuring the continuity of the discharge process.

[0020] 2. The device is equipped with an air pump and air inlet that outputs directional airflow. The airflow direction is parallel to the center line of the arc-shaped bottom of the hopper at the top of the drive wheel. This provides auxiliary pushing for the material during the hopper unloading stage. Combined with the guiding trajectory of the guide channel, it stably pushes the gathered Sophora japonica buds towards the discharge port, improving the problem of insufficient throwing distance and incomplete unloading caused by the inherent characteristics of Sophora japonica buds. The narrow strip-shaped hole on the arc-shaped bottom of the hopper forms a cooperative structure with the rotating bar. In its initial state, the rotating bar covers the narrow strip-shaped hole, ensuring the integrity of the material during hopper lifting and preventing premature spillage. When the hopper rotates to the unloading position, the rotating bar rotates around the axis, assisting in throwing the Sophora japonica buds out of the hopper, improving the completeness of unloading. After rotating 90 degrees, the narrow strip-shaped hole is exposed, guiding the airflow from the air inlet forward, allowing the airflow to act more precisely on the material, enhancing the airflow-assisted unloading effect, while avoiding excessive impact on the Sophora japonica buds, reducing material breakage, protecting the integrity of the raw material, and facilitating the stable operation of the subsequent rutin extraction process.

[0021] 3. The guide plate 2 and the magnets on the hopper are arranged with opposite magnetic properties on opposite sides. When the hopper completes unloading and moves downwards, the repulsive force between the magnets can drive the guide plate 2 to rotate around the connecting shaft. This achieves the linkage action of the guide plate 2 without the need for additional power components. During the rotation of the guide plate 2, it further guides the airflow towards the discharge port, carrying residual material towards the discharge port and improving the thoroughness of material discharge. After the hopper is removed, the guide plate 2 can be reset to the limit edge position under the action of a torsion spring. This, combined with the left limit component, limits the rotation amplitude, ensuring the stability and regularity of the reciprocating motion of the guide plate 2 and maintaining the consistency of the overall device operation. The magnet built into the lower side of the guide plate 2 forms a stable magnetic attraction linkage with the magnet on the outer side of the hopper connecting plate. This simple structure and reliable operation reduce the device's failure rate and minimize subsequent maintenance workload.

[0022] 4. The guide plate is connected to the grounding wire and grounded. Static electricity generated by friction during the conveying process of the Sophora japonica buds can be quickly conducted to the ground through contact with the guide plate, preventing the continuous accumulation of static electricity in the material and inside the machine casing. This eliminates the risk of discharge caused by static electricity buildup and reduces the adhesion of Sophora japonica buds to the hopper, machine casing, and inner wall of the guide channel due to static adsorption, further alleviating material retention and backflow problems. A directional and low-speed airflow along the guide channel can disperse the accumulated fine powder of the Sophora japonica buds, preventing dense powder accumulation and the formation of high-charge areas. This reduces the intensity of static electricity generation from the source, working synergistically with the grounded guide structure to comprehensively ensure electrostatic safety during the conveying process, meeting the safety and cleanliness requirements of rutin pharmaceutical raw material production.

Detailed Implementation

[0025] 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.

[0026] Example 1, see Figures 1-8 This invention provides a technical solution: a special controllable feeding and conveying device for rutin production raw materials, including a housing 100. The lower right and upper left parts of the housing 100 are respectively provided with a feed inlet 101 and a discharge outlet 102. A grounding wire 108 is provided on the outside of the housing 100. A driven wheel 112 and a driving wheel 113 are provided inside the housing 100. A chain 111 is provided on the driven wheel 112 and the driving wheel 113. Several hoppers 110 are provided on the chain 111. An air pump 104 is provided on the right side of the housing 100. The air pump 104 is connected to the air outlet 109 of the housing 100 through an air pipe 105. A guide plate 114 is provided on the inner wall of the housing 100 near the top. An air pump 104 is mounted on a support leg 103, which is located on the right side of the housing 100 at the same horizontal level as the discharge port 102. An air inlet 109 is located on the right side wall of the housing 100 at the connection point of the air pipe 105. A motor 106 is mounted next to the air pump 104, and the motor 106 is connected to the drive wheel 113 via a connector 107.

[0027] Specifically, the casing 100 serves as the overall load-bearing and enclosed protective structure. The feed inlet 101 is located at the lower right of the casing 100, and the discharge outlet 102 is located at the upper left of the casing 100. This meets the vertical continuous feeding requirements of Sophora japonica flowers, enabling vertical transfer of raw materials within a limited space and reducing the area occupied in the production area. Simultaneously, the enclosed casing 100 reduces the spillage of fine powder from the Sophora japonica flowers, maintaining a clean production environment. The casing 100 is internally equipped with a driven wheel 112 and a driving wheel 113, which work in conjunction with a chain 111 to achieve cyclic transmission. Several hoppers 110 are evenly arranged on the chain 111. The continuous rotation of the driving wheel 113 drives the chain 111 and the hoppers 110 to run at a uniform speed, allowing the hoppers 110 to stably receive the Sophora japonica flowers entering from the feed inlet 101 and gradually lift them to the height of the discharge outlet 102, forming a continuous and stable material conveying foundation. This transmission method has a mature structure, runs smoothly, and ensures the continuity and reliability of the Sophora japonica flower feeding process. The motor 106 is located next to the air pump 104 and is connected to the drive wheel 113 via the connector 107. It can provide a stable and controllable power output to the drive wheel 113, making it easy to adjust the running speed according to the amount of locust flowers being conveyed, and adapt to the feeding requirements under different working conditions.

[0028] The support leg 103 is fixed to the right side of the housing 100 and is at the same level as the discharge port 102. It is mainly used to support the air pump 104, so that the installation height of the air pump 104 matches the air outlet 109 on the housing 100, shortening the connection length of the air pipe 105, reducing the pressure loss and path bend of the airflow during transmission, and ensuring that the airflow can be delivered to the air outlet 109 in a stable state. At the same time, it makes reasonable use of the idle space on the outside of the housing 100, making the layout of the air pump 104 and the motor 106 more regular, avoiding mutual interference between components, and facilitating the installation, debugging and subsequent maintenance of the equipment. The air pump 104 is connected to the air inlet 109 of the housing 100 via the air pipe 105. The air inlet 109 is precisely set at the connection position of the air pipe 105 on the right side wall of the housing 100. It can directionally introduce external airflow into the unloading area inside the housing 100. The airflow can directly act on the locust flowers in the hopper 110 that has been lifted to the top, helping the material overcome its own adhesion and poor flowability, improving the fullness of unloading, and reducing material residue and backflow.

[0029] A guide plate 114 is installed near the top of the inner wall of the casing 100. This guide plate collects and guides the Sophora japonica buds that are not completely thrown from the hopper 110 or fall back along the inner wall of the casing 100, thus constraining the movement trajectory of the material and preventing it from scattering into dead corners inside the casing 100 or falling back to the bottom of the equipment. This reduces the energy consumption and raw material loss caused by ineffective conveying. A grounding wire 108 is installed on the outside of the hopper 110. This grounding wire, in conjunction with the conductive structure of the guide plate 114, quickly conducts the static electricity generated by the Sophora japonica buds during conveying and friction to the ground. This prevents static electricity from accumulating on the material surface and the inner wall of the equipment. This not only alleviates the problem of Sophora japonica buds adhering to the hopper 110 and the inner wall of the casing 100 due to electrostatic adsorption, but also eliminates the safety hazards caused by electrostatic discharge, meeting the safety and cleanliness requirements of Sophora japonica buds as a medicinal raw material.

[0030] The structural layout is designed to adapt to the characteristics of Sophora japonica flowers, integrating power transmission, airflow-assisted unloading, material guidance, and static discharge functions into one unit. The positions of each component are adapted to each other and work together, which not only ensures the stability and efficiency of Sophora japonica flower conveying, but also solves practical problems such as incomplete unloading, material return and leakage, and static electricity accumulation. The overall structure is simple and compact, and the operation is reliable. It can effectively improve the overall effect of raw material feeding and conveying in rutin production, reduce raw material loss and equipment failure probability, and meet the needs of continuous industrial production.

[0031] Example 2, see Figures 1-8 The discharge port 102 is angled from right to left and its cross-section decreases from large to small. The guide plate 114 includes an ascending section 1141, a horizontal section 1142, and a descending section 1143, which are connected in a circular arc. The starting point of the ascending section 1141 is parallel to the center line of the arc-shaped bottom 124 of the hopper 110 at the top of the drive wheel 113. The air inlet 109 is parallel to the center line of the arc-shaped bottom 124 of the hopper 110 at the top of the drive wheel 113. The horizontal section 1142 is parallel to the top surface of the casing 100, and the descending section 1143 is parallel to the discharge port 102. The guide groove formed between the guide plates 114 facilitates the limiting and guiding of the locust flowers. One end of the grounding wire 108 is connected to the guide plate 114, and the other end is grounded.

[0032] Specifically, the discharge port 102 adopts a design that slopes from right to left and gradually decreases in cross-section. Its core purpose is to conform to the movement trajectory of the Sophora japonica buds after they are thrown from the hopper 110, and at the same time adapt to the guiding direction of the guide plate 114. The gradual decrease in cross-section can gradually shrink the flow space of the material, so that the dispersed Sophora japonica buds gradually converge, avoiding the material from dispersing and accumulating at the discharge port 102, ensuring the smoothness of the discharge process, reducing the residue of fine Sophora japonica bud powder at the edge of the discharge port 102, and the slope setting can use the material's own gravity to assist the discharge, reducing the probability of material blockage at the discharge port 102. It also adapts to the poor flowability of Sophora japonica buds, ensuring that the material can be discharged from the equipment stably and continuously, providing a uniform raw material supply for the subsequent rutin extraction process.

[0033] The guide plate 114 is divided into an ascending section 1141, a horizontal section 1142, and a descending section 1143, with the three sections connected by an arc. This segmented structure can precisely adapt to the movement trajectory of the Sophora japonica buds inside the casing 100. The arc connection design can prevent material from getting stuck or accumulating at the segmented connection points of the guide plate 114, reduce friction between the Sophora japonica buds and the guide plate 114, reduce the probability of Sophora japonica bud breakage, and also reduce material residue, making it easier to clean the equipment later, meeting the cleanliness requirements for pharmaceutical raw material production. The starting point of the ascending section 1141 is parallel to the center line of the arc-shaped bottom 124 of the hopper 110 at the top of the drive wheel 113, which can accurately receive the material thrown from the hopper 110, especially the Sophora japonica buds with a short throwing distance and not completely leaving the hopper 110, avoiding direct impact of the material with the guide plate 114 and causing breakage. At the same time, it can also guide the material smoothly into the guide trajectory of the guide plate 114, reducing material rebound and the occurrence of material return.

[0034] The air inlet 109 is parallel to the center line of the arc-shaped bottom 124 of the hopper 110 at the top of the drive wheel 113. This ensures that the airflow delivered by the air pump 104 is consistent with the direction of the material thrown from the hopper 110. The airflow can directly act on the incompletely thrown locust flowers in the hopper 110 and the material adhering to the inner wall of the hopper 110, helping the material overcome its own adhesion and smoothly detach from the hopper 110. This improves the fullness of unloading, reduces material residue in the hopper 110, thereby reducing the return rate and improving the effective conveying efficiency of the equipment. At the same time, the airflow direction is consistent with the material throwing direction, which can avoid the airflow causing reverse impact on the material and prevent the material from being blown back into the casing 100, further reducing ineffective conveying.

[0035] The horizontal section 1142 is parallel to the top surface of the casing 100, providing a stable guiding space for the projected Sophora japonica flowers. This allows the dispersed flowers to gradually stabilize within the horizontal section 1142, reducing collisions between materials and minimizing the generation of fine powder. Simultaneously, the horizontal section 1142 buffers the material's movement speed, preventing it from colliding with the descending section 1143 due to excessive speed, further protecting the integrity of the raw material. The descending section 1143 is parallel to the discharge port 102, smoothly guiding the material from the horizontal section 1142 to the discharge port 102. This ensures the material's trajectory aligns with the convergence direction of the discharge port 102, achieving a smooth transition from the guide plate 114 to the discharge port 102. This prevents material accumulation at the end of the guide plate 114, further reducing material return and leakage.

[0036] The guide channel formed between the guide plate and 114 can effectively limit and guide the Sophora japonica buds, restricting their movement range inside the casing 100, preventing them from scattering along the inner wall of the casing 100 into dead corners or falling back to the bottom of the casing 100, thus reducing material loss. At the same time, it can also make the material move along a preset trajectory, facilitating better airflow to assist in pushing the material, improving the effect of airflow-assisted unloading, and enabling the material to move towards the discharge port 102 in a concentrated and stable manner, thereby improving the overall conveying efficiency. One end of the grounding wire 108 is connected to the guide plate 114, and the other end is grounded. Utilizing the conductivity of the guide plate 114, the static electricity generated by the friction between the Sophora japonica buds and the hopper 110, the casing 100, and the guide plate 114 during the conveying process is quickly conducted to the ground. This prevents the accumulation of static electricity on the material surface and the inner wall of the equipment. It can alleviate the problem of Sophora japonica buds adhering to the guide plate 114, the hopper 110, and the inner wall of the casing 100 due to electrostatic adsorption, reduce material retention and backflow, eliminate the safety hazards caused by electrostatic discharge, prevent electrostatic sparks from igniting the fine powder of Sophora japonica buds, and at the same time ensure the cleanliness of the Sophora japonica bud raw material, which meets the safety and quality standards for the production of rutin medicinal raw materials.

[0037] The overall design revolves around the characteristics of Sophora japonica flowers, such as strong adhesion, poor flowability, and easy generation of static electricity. Through the directional adaptation and arc connection of each section of the guide plate 114, as well as its coordination with the air inlet 109 and the discharge outlet 102, the material is accurately guided, fully unloaded, and static electricity is discharged. The various structures are mutually adapted and work together, which not only reduces material loss and equipment energy consumption, but also ensures the safety, cleanliness, and stability of the conveying process, thus meeting the needs of continuous industrial production of rutin.

[0038] Example 3, see Figures 1-8A guide plate 116 is provided at the connection between the discharge port 102 and the inner wall of the casing 100. A left limiting member 117 is provided on the left side of the guide plate 116, and a limiting edge 118 is provided on the right side of the guide plate 116. A connecting hole 119 is provided at the end of the guide plate 116, and a connecting shaft 120 is provided in the connecting hole 119. A torsion spring 121 is provided on the connecting shaft 120. A magnet 122 is built into the lower side of the guide plate 116. The hopper 110 is composed of an arc-shaped bottom 124, a connecting side plate 126, and a opposing side plate 127. The connecting side plate 126 is connected to the chain 111, and a magnet 123 is provided on the outer side of the connecting side plate 126. The magnets 122 and 123 have opposite magnetic properties on their opposite sides.

[0039] Specifically, a guide plate 116 is provided at the connection between the discharge port 102 and the inner wall of the casing 100. This guide plate 116 can fill the gap between the guide plate 114 and the discharge port 102, preventing the Sophora japonica buds from accumulating and stagnating at the connection point. This ensures a smooth transition of material from the guide plate 114 to the discharge port 102, further reducing material return. At the same time, it can guide the airflow to form a stable flow trajectory at the connection point, enhancing the effect of airflow-assisted unloading. This is suitable for the characteristics of Sophora japonica buds, which have poor flowability and are easy to adhere, ensuring that the material can continuously and stably enter the discharge port 102. The guide vane 116 has a left limiting element 117 on the left and a limiting edge 118 on the right. The two work together to precisely limit the rotation range of the guide vane 116, preventing it from colliding with the inner wall of the housing 100, the hopper 110, or the discharge port 102 due to excessive rotation angle, thus avoiding damage to the components. At the same time, it also prevents the rotation angle from being too small, which would not be able to effectively guide the material, ensuring that the guiding effect of the guide vane 116 is stable and reliable.

[0040] A connecting hole 119 is provided at the end of the second guide plate 116, and a coupling shaft 120 is installed in the connecting hole 119. The coupling shaft 120 provides a stable rotation fulcrum for the second guide plate 116, allowing the second guide plate 116 to rotate flexibly around the coupling shaft 120, avoiding jamming or other phenomena during rotation, and ensuring the smooth operation of the second guide plate 116. A torsion spring 121 is provided on the coupling shaft 120. The torsion spring 121 can use its own elastic force to automatically drive the second guide plate 116 to return to its initial position after it is pushed to rotate. There is no need to add an additional power component, which simplifies the equipment structure, reduces energy consumption, and ensures that the second guide plate 116 is in the appropriate initial position every time the hopper 110 passes by, achieving stable linkage and ensuring the stability of continuous equipment operation.

[0041] The lower side of the flow guide plate 2 116 has a built-in magnet 122, which can prevent magnet 122 from directly contacting the material and prevent Sophora japonica buds from adhering to the magnet surface and affecting the magnet linkage effect. At the same time, it can also protect magnet 122 from damage caused by friction and collision of the material, extend the service life of magnet 122, and the built-in design can ensure the flatness of the surface of the flow guide plate 2 116, reduce the residue of material on the surface of the flow guide plate 2 116, facilitate subsequent cleaning, and meet the cleanliness requirements of pharmaceutical raw material production. The hopper 110 consists of an arc-shaped bottom 124, a connecting side plate 126, and a counter side plate 127. The connecting side plate 126 is connected to the chain 111, which can firmly fix the hopper 110 to the chain 111, preventing the hopper 110 from loosening or falling off during lifting and unloading, and ensuring the stability of the hopper 110 operation. The arc-shaped bottom 124 can better hold the locust flowers and reduce the residue of locust flowers in the hopper 110. The counter side plate 127 can limit the locust flowers from both sides to prevent the locust flowers from spilling from the sides of the hopper 110 during lifting, thereby reducing material loss.

[0042] A magnet 123 is installed on the outer side of the connecting side plate 126. Magnet 122 and magnet 123 have opposite magnetic properties on their opposite sides. Utilizing the physical property of opposite poles repelling each other, when the hopper 110 completes unloading and moves downward, magnet 123 on the connecting side plate 126 will gradually approach magnet 122 on the lower side of the guide plate 116. The repulsive force generated between the two will push the guide plate 116 to rotate around the connecting shaft 120. During the rotation of the guide plate 116, it can further guide the airflow towards the discharge port 102, and at the same time push the residual material at the connection point towards the discharge port 102, improving the thoroughness of material discharge and reducing material return and material loss. This magnet linkage structure does not require additional power to drive, the linkage action is reliable and precise, and the structure is simple with a low failure rate. It can further optimize the material conveying effect without increasing the complexity of the equipment and energy consumption, and is suitable for the characteristics of Sophora japonica flowers with strong adhesion and easy return.

[0043] The overall structural design aligns with the integrated control and conveying requirements of the equipment. The rotational linkage of the guide plate 116 and the precise coordination of the hopper 110's running trajectory ensure timely and effective material guidance. The cooperation between the left limiter 117, the limit edge 118, and the torsion spring 121 guarantees the stability and regularity of the guide plate 116's movement. The opposing pole repulsion design of magnet 122 and magnet 123 achieves powerless linkage, simplifying the structure while improving the reliability of equipment operation. All components are mutually compatible and work synergistically, further reducing material return, accumulation, and loss during the sophora japonica bud conveying process, ensuring smooth and stable feeding and conveying, meeting the conveying requirements of sophora japonica buds, the raw material for rutin production, and helping to improve overall production efficiency and raw material utilization.

[0044] Example 4, see Figures 1-8The arc-shaped bottom 124 has evenly distributed narrow strip holes 128, and arc edges 130 and 131 are provided on both sides of the narrow strip holes 128. Rotating bars 125 are provided on the narrow strip holes 128, arc edges 130 and 131. The rotating bars 125 are located at one end of arc edge 130 and are rotatably mounted on the two side plates of the arc-shaped bottom 124 via a rotating shaft 129.

[0045] Specifically, the arc-shaped bottom 124 serves as the supporting bottom surface of the hopper 110. Its arc-shaped structure can better conform to the loading and throwing trajectory of the Sophora japonica flowers, reducing the residue of Sophora japonica flowers in the corners of the hopper 110. The evenly arranged narrow strip holes 128 on the arc-shaped bottom 124 are designed to work with the airflow introduced through the air inlet 109 to achieve precise auxiliary unloading. Utilizing the air permeability of the narrow strip holes 128, the airflow can smoothly penetrate the arc-shaped bottom 124 and act on the Sophora japonica flowers in the hopper 110, especially the material adhering to the inner wall of the arc-shaped bottom 124, helping the material overcome its own adhesion and detach from the hopper 110. At the same time, the evenly arranged narrow strip holes 128 can make the airflow more uniform, avoiding the problem of excessive local airflow causing Sophora japonica flower powder to fly away, or insufficient local airflow failing to achieve auxiliary unloading, thus balancing the unloading effect and the integrity of the raw materials.

[0046] The arc edges 130 and 131 on both sides of the narrow strip hole 128 are designed to prevent the edges of the narrow strip hole 128 from forming right angles. Right angles can easily cause the Sophora japonica buds to get stuck, accumulate, or even be scratched and broken during conveying and unloading. The arc transition design of the arc edges 130 and 131 reduces the frictional resistance between the Sophora japonica buds and the edges of the narrow strip hole 128, reduces the probability of Sophora japonica bud breakage, protects the integrity of the Sophora japonica bud raw material, and facilitates the stable operation of the subsequent rutin extraction process. At the same time, it can also reduce the adhesion residue of Sophora japonica buds on the edges of the narrow strip hole 128, making it easier to clean the hopper 110 later, which meets the cleanliness requirements for pharmaceutical raw material production. In addition, the arc edges can also prevent turbulence when the airflow passes through the narrow strip hole 128, ensuring the stability of the airflow and allowing the airflow to act on the Sophora japonica buds more smoothly.

[0047] The rotating bar 125 is mounted on the narrow slot 128, the first arc edge 130, and the second arc edge 131. The rotating bar 125 is located at one end of the first arc edge 130 and is rotatably mounted on both sides of the arc-shaped bottom 124 via a rotating shaft 129. Its design principle utilizes the centrifugal force of the hopper 110 rotating at the top of the drive wheel 113 to drive the rotating bar 125 to rotate flexibly around the rotating shaft 129, achieving a linkage effect of "blocking during loading and opening during unloading." During the process of the hopper 110 receiving and lifting the locust flowers, the rotating bar 125 is in a naturally drooping state, completely blocking the narrow slot 128, preventing locust flower particles or fine powder from leaking out of the narrow slot 128, ensuring the effective loading capacity of the hopper 110, reducing material loss during the lifting process, and also preventing airflow from prematurely passing through the narrow slot 128 during lifting, which could affect the stable loading of the locust flowers.

[0048] When the hopper 110 rotates with the chain 111 to the top of the drive wheel 113 and begins to discharge material, the rotating bar 125 rotates counterclockwise around the shaft 129 under the action of centrifugal force. During the rotation, it can generate an outward thrust on the locust flowers in the hopper 110, helping the locust flowers overcome the adhesion and be thrown out, improving the fullness of discharge, reducing material residue in the hopper 110, and thus reducing the occurrence of material return. When the rotating bar 125 rotates 90 degrees, it will fully open the narrow strip orifice 128. At this time, the airflow introduced through the air inlet 109 can accurately act on the locust flowers that have not been fully thrown and the residual material in the hopper 110 through the narrow strip orifice 128, further pushing the material to move towards the discharge port 102. This works in conjunction with the guiding effect of the first guide plate 114 and the second guide plate 116 to enhance the auxiliary discharge effect.

[0049] The rotating shaft 129 provides a stable fulcrum for the rotating bar 125, ensuring that the rotating bar 125 can rotate flexibly and smoothly under centrifugal force, avoiding jamming or sticking, and ensuring the reliability of the rotating bar 125's operation. This, in turn, ensures that the hopper 110 can achieve stable linkage action every time it unloads. The entire structural design does not require additional power components; it only relies on the centrifugal force of the hopper 110 itself to open and close the rotating bar 125. This simplifies the structure of the hopper 110, reduces the equipment failure rate and subsequent maintenance workload, and effectively balances the stability of the locust flower loading and the thoroughness of unloading. It also caters to the material characteristics of locust flowers, which are highly adhesive, have poor flowability, and are prone to residue, reducing material loss and return rate, improving the effective conveying efficiency of the equipment, and protecting the integrity of the locust flower raw material, meeting the conveying requirements of rutin production raw materials.

[0050] The following is combined Figures 1-8 Explain its working process: In response to the characteristics of Sophora japonica buds being lightweight, sticky, and having poor flowability, this device operates by starting the motor 106. The motor 106 drives the drive wheel 113 to rotate via the connecting piece 107, which in turn drives the driven wheel 112 and the hopper 110 on the chain 111 to rotate via the chain 111. Sophora japonica buds are fed into the feed inlet 101. After entering the hopper 110, the Sophora japonica buds are lifted to the top of the drive wheel 113 and then thrown out into the discharge outlet 102, from which they are discharged. During this process, the air pump 104 is activated to introduce airflow into the air inlet 109. The airflow is parallel to the center line of the arc-shaped bottom 124 of the hopper 110 at the top of the drive wheel 113. When the hopper 110 is on the drive wheel 113, the rotating bar 125 on the arc-shaped bottom 124 is initially blocking the narrow strip hole 128. The rotating bar 125 of the arc-shaped bottom 124 rotates counterclockwise around the rotating shaft 129. During the rotation of the rotating bar 125, it assists in throwing out the Sophora japonica flowers. The rotating bar 125 rotates 90 degrees. After reaching the desired depth, the narrow strip-shaped hole 128 on the arc-shaped bottom 124 can guide the airflow from the air inlet 109 to the front. At the same time, it works in conjunction with the guide plate 114 set on the inner wall of the casing 100. The guide plate 114 forms a guide channel, which includes an ascending section 1141, a horizontal section 1142, and a descending section 1143. When the locust flowers, fine powder, and fragments that are not fully thrown from the hopper 110 and fall back into the hopper slide down the casing 100, they are collected and limited by the guide channel, so that they do not scatter into the dead corner of the casing 100 or fall directly back to the lower part of the barrel. The locust flowers are pushed by the airflow through the ascending section 1141, the horizontal section 1142, and the descending section 1143 to the discharge port 102 and finally discharged from the discharge port 102. Meanwhile, since the magnet 123 on the connecting side plate 126 of the hopper 110 has opposite magnetism to the magnet 122 at the bottom of the guide plate 116, when the hopper 110 throws the sophora flowers and moves downward, the magnet 123 will exert a pushing force on the magnet 122, causing the guide plate 116 to rotate counterclockwise around the connecting shaft 120 to the left limiting member 117. During this process, the rotation of the guide plate 116 guides the airflow to move towards the discharge port 102, driving the sophora flowers to the discharge port 102. After the hopper 110 moves downward, the guide plate 116 rotates in the opposite direction to the limiting edge 118 due to the action of the torsion spring 121. At the same time, the directional, low-speed airflow along the guide channel will disperse the gathered Sophora japonica powder, preventing the powder from densely accumulating and forming a strongly charged area, thus avoiding "a small local pile of powder carrying a large amount of static electricity" and reducing the probability of discharge from the source; the guide plate 114 is connected to the grounding wire 108, which will cause the static-charged Sophora japonica to be instantly grounded through the contact guide channel, completely eliminating the accumulation of static electricity.
