Description

Technical Field

[0001] This invention relates to the field of animal husbandry technology, specifically to a disease prevention and isolation device for animal husbandry and veterinary medicine. Background Technology

[0002] Animal husbandry is a vital component of the agricultural economy, and animal disease prevention and control directly impacts farming efficiency and public health safety. Within the animal husbandry and veterinary disease prevention system, isolation devices are fundamental equipment for physically blocking disease transmission and preventing cross-infection. Their core function is to construct independent isolation spaces using fences and modular barriers, separating sick animals from healthy individuals and allowing for medication and other disease prevention procedures during isolation. With the development of large-scale farming, modular barrier-style isolation devices not only need to fulfill basic spatial separation functions but also require adjustable structural designs to adapt to different animal enclosure openings and isolation scenarios. They must also integrate convenient and safe drug storage and administration mechanisms to reduce the workload of disease prevention personnel and improve disease control efficiency.

[0003] However, existing animal husbandry and veterinary disease prevention and isolation devices still have significant shortcomings in practical applications. Traditional isolation fences are mostly fixed rigid structures, and the fence panels cannot be adjusted to accommodate the actual opening size of the animal shed or isolation requirements, resulting in poor adaptability to the isolation space and insufficient installation flexibility. Furthermore, the medication delivery of existing devices largely relies on disease prevention personnel directly entering the isolation area, increasing the risk of human-animal contact and potentially leading to secondary infections. In addition, existing feeding mechanisms lack effective drug storage and controllable dispensing designs, making it easy for drugs to accumulate, clog, or distribute unevenly during storage and delivery. Moreover, the opening and closing of the dispensing port is mostly manually controlled, lacking linkage with the fence structure, resulting in low automation and making it difficult to achieve safe, convenient, and accurate isolation and medication delivery operations.

[0004] Therefore, we have proposed a disease prevention and isolation device for animal husbandry and veterinary medicine to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a disease prevention and isolation device for animal husbandry and veterinary medicine, to solve the problems of poor adaptability caused by the fixed size of existing isolation fences, the risk of cross-infection due to manual drug administration, and easy blockage of drug dispensing. The device includes a fence and a combined fence. The combined fence is composed of a hollow first fence panel and a hollow second fence panel slidably disposed within it, connected together. The second fence panel has a built-in feeding mechanism, which includes a storage bin, a valve, a dispensing port, and a baffle. A divider is installed in the storage bin to achieve dual-end drug diversion. An adjustment mechanism consisting of guide posts and springs is installed in the second fence panel to assist in the automatic opening and closing of the baffle. The dispensing device receives the dispensing port to guide the flow. A spring plate connects the divider and the dispensing device to provide ejection power. A sliding mechanism, guide rod, intermittent protrusions, and the first and second moving mechanisms work together to achieve directional sliding of the dispensing device, vibration anti-blocking, and guiding limit. Through the interlocking fence structure, it adapts to different animal pen sizes, integrating drug storage, diversion, guidance, controllable opening and closing, and elastic pushing functions within the fence, achieving non-contact and safe drug administration.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a disease prevention and isolation device for animal husbandry and veterinary medicine, comprising a fence and a combined fence, wherein the combined fence comprises a first fence panel and a second fence panel, the first fence panel is fixedly mounted on the fence and is hollow, the second fence panel is slidably mounted inside the first fence panel and is hollow, and a feeding mechanism is provided inside the second fence panel, the feeding mechanism being used to feed medicine; The feeding mechanism includes a storage compartment disposed within the second fence panel. The top of the storage compartment is open, and a valve is provided at the top of the storage compartment for opening and closing the storage compartment. A discharge port is provided at the bottom of the storage compartment, and the discharge port penetrates the second fence panel for drug feeding. The second fence plate is provided with a baffle, which is used to open and close the feed port.

[0007] Preferably, the storage chamber is equipped with a divider, which is used to divert the drugs put into the storage chamber for double-ended feeding.

[0008] Preferably, the second fence plate is provided with an adjustment mechanism, which is used to assist the baffle in automatically opening and closing the feed port; The adjustment mechanism includes a guide post disposed inside the second fence panel, a spring sleeved on the guide post, one end of the spring being fixedly connected to the second fence panel, and the other end of the spring being fixedly connected to a baffle.

[0009] Preferably, a feeder is also provided inside the second fence panel, which is used to assist the drugs in entering the animal shed.

[0010] Preferably, the storage compartment is provided with a spring plate, one end of which is slidably mounted on the feeder, and the other end of which is fixedly mounted on the divider. The spring plate is used to assist the feeder in ejecting the second grid plate.

[0011] Preferably, the storage compartment is further provided with a sliding mechanism, and the feeder is slidably connected to the storage compartment through the sliding mechanism; The feeder includes a sliding groove formed in the storage compartment, and a sliding block adapted to the sliding groove is provided at the bottom of the feeder. The sliding block is slidably disposed in the sliding groove.

[0012] Preferably, a guide rod is also provided in the sliding groove, and the sliding block is slidably disposed on the guide rod.

[0013] Preferably, the sliding groove is further provided with protrusions, which are intermittently arranged in the sliding groove. The protrusions are used to intermittently abut against the sliding block, so that the feeder vibrates when it slides.

[0014] Preferably, the feeder is further provided with a first moving mechanism, and the sliding block is slidably connected to the feeder through the first moving mechanism; The first moving mechanism includes a first moving groove formed in the feeder, and a first moving block adapted to the first moving groove is provided on the sliding block. The first moving block is slidably disposed in the first moving groove, and a first limiting rod is provided in the first moving groove. The first moving block is slidably disposed on the first limiting rod.

[0015] Preferably, the feeder is further provided with a second moving mechanism, and the spring plate is slidably connected to the feeder through the second moving mechanism; The second moving mechanism includes a second moving groove opened in the feeder, a second moving block adapted to it is provided in the second moving groove, the second moving block is slidably disposed in the second moving groove, one end of the spring plate near the feeder is fixedly disposed on the second moving block, a second limiting rod is also provided in the second moving groove, and the second moving block is slidably disposed on the second limiting rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. By using a hollow sliding structure with inner and outer fittings between the first and second fence panels, the overall length of the combined fence can be adjusted, allowing the isolation device to adapt to entrances of different animal pens, avoiding installation redundancy or isolation gaps caused by size mismatches in traditional fixed fences. The feeding mechanism is built into the hollow cavity of the second fence panel, and with dual-opening and closing control of valves and baffles, epidemic prevention personnel can complete drug loading and dispensing without entering the isolation area, cutting off the path of cross-infection between humans and animals. The divider enables simultaneous feeding from both ends, expanding the drug distribution range, avoiding single-point accumulation, improving drug utilization and feeding uniformity, and enhancing the safety and standardization of epidemic prevention operations.

[0017] 2. The adjustment mechanism, through the coordinated action of guide columns and springs, constructs an elastic automatic reset mechanism for the baffle. Under normal conditions, the baffle remains normally closed and sealed. It automatically opens during feeding and returns to its original position afterward, achieving semi-automatic control of the feeding port's opening and closing, reducing manual operation intensity and preventing drug leakage. The feeder forms a closed flow channel, delivering the drug along a predetermined path to the target area in the animal enclosure, avoiding scattering and deviation caused by free fall. The spring plate utilizes elastic potential energy to propel the feeder outward from the fence, shortening the drug's descent distance and reducing splashing and dust generation caused by the impact of the fall, ensuring animals receive the required dosage and maintaining a clean isolation environment.

[0026] 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.

[0027] Example 1: Please refer to Figure 1 - Figure 7 A livestock and veterinary disease prevention and isolation device includes a fence 1 and a combined fence 2. The fence 1 is a rectangular frame welded from metal tubing, with anchor bolts or pre-embedded parts at the bottom for a stable connection to the ground and to define the boundary of the isolation area. The combined fence 2 includes a first fence plate 21 and a second fence plate 22. The first fence plate 21 is made of hollow square tubing, with one end fixed to a post on one side of the fence 1 by welding or bolting, and the tubing extending horizontally. The second fence plate 22 is also made of hollow square tubing, with an outer contour dimension slightly smaller than the inner diameter of the tubing of the first fence plate 21. It slides horizontally within the tubing of the first fence plate 21, and the two are fitted together to allow for sliding expansion and contraction, adjusting the overall length of the combined fence 2. A feeding mechanism 3 is installed within the tubing of the second fence plate 22. The feeding mechanism 3 includes a storage bin 31, a valve 32, and a discharge port 33. The storage bin 31 is a rectangular bin with an open top, its outer wall fixedly connected to the inner wall of the second fence plate 22, and its top opening for receiving medication. Valve 32 is a flip-top plate hinged to the edge of the top opening of storage bin 31, rotating around the hinge axis to open and close storage bin 31. A discharge port 33 is provided at the bottom of storage bin 31. The discharge port 33 is a circular or rectangular through-hole that penetrates vertically through the bottom plate of the second fence plate 22, allowing medicine from storage bin 31 to fall into the animal enclosure. A baffle 5 is also provided on the second fence plate 22. The baffle 5 is a rectangular sliding plate that slides horizontally along the outer or inner side of the bottom wall of the second fence plate 22 via a guide rail groove structure, allowing it to open and close the discharge port 33 by pushing and pulling.

[0028] In this embodiment: During operation, the fence 1 is first fixed to the entrance of the animal shed. The overall length of the combined fence 2 is adjusted by pulling the second fence panel 22 according to the width of the entrance, thus constructing an isolation space. The valve 32 is opened to add medicine to the storage bin 31 and then closed. When feeding, the sliding baffle 5 opens the feed port 33, and the medicine falls into the animal shed under the action of gravity through the feed port 33.

[0029] By designing the first fence panel 21 and the second fence panel 22 as a hollow sliding structure with inner and outer fittings, the limitation of the traditional fixed fence size being non-adjustable is overcome. This allows for expansion and contraction adaptation according to the width of the animal enclosure entrance, improving the versatility and installation flexibility of the isolation device in animal enclosures of different sizes, and avoiding isolation gaps or installation redundancy caused by size mismatch. The feeding mechanism 3 is integrally built into the hollow cavity of the second fence panel 22, integrating the drug storage and dispensing functions with the isolation fence structure. Epidemic prevention personnel only need to load the drug through the valve 32 and operate the baffle 5 from outside the fence to complete the drug dispensing, without entering the isolation area, cutting off the cross-infection path between humans and animals, and improving the safety of epidemic prevention operations. The valve 32 and the baffle 5 form a two-level control for drug storage and dispensing: the valve 32 seals the top opening of the storage chamber 31 to prevent the drug from being contaminated by moisture or accidentally spilling; the baffle 5 precisely opens and closes the feeding port 33 to control the timing and dosage of feeding. The two work together to achieve temporary drug storage protection and precise dispensing, solving the problems of easy contamination from exposed drug storage and difficulty in controlling the dosage of manual drug dispensing in existing technologies.

[0030] Example 2: Please refer to Figure 1 - Figure 7 The storage chamber 31 is also equipped with a divider 4. The divider 4 has a V-shaped or Y-shaped guide plate structure, made of stainless steel sheet by stamping and bending. The upper part is a single inlet, and the lower part is symmetrically branched to form two discharge channels. The ends of the two discharge channels are respectively connected to the two discharge ports 33 at the bottom of the storage chamber 31, or the lower outlet of the divider 4 extends to the two discharge ports 33 through guide pipes. The upper inlet of the divider 4 receives the medicine falling from the storage chamber 31, and the branching structure evenly distributes it to the two discharge directions.

[0031] In this embodiment: during operation, the drug falls into the storage chamber 31 and then gathers at the upper inlet of the divider 4. Under the action of gravity, it flows along the two discharge channels to the two discharge ports 33 respectively, realizing synchronous discharge at both ends.

[0032] By adding a divider 4 inside the storage chamber 31, the drug flow within a single storage space is actively diverted into a dual-end discharge, overcoming the drawbacks of limited feeding coverage and drug accumulation at a single discharge point caused by a single discharge port 33. Dual-end discharge allows the same batch of drugs to be simultaneously delivered to two different locations within the isolation area, expanding the drug distribution area. This is suitable for uniform drug delivery in isolation of multiple animals or in long, narrow animal pens, avoiding uneven feeding or excessively high local drug concentrations caused by single-point feeding. The V-shaped or Y-shaped flow guide structure of the divider 4 utilizes gravity flow for passive diversion, requiring no additional power unit. The symmetrical bifurcation design ensures balanced discharge at both ends, improving drug utilization and feeding efficiency, and expanding feeding functionality while maintaining a simple structure. Example 3: Please refer to Figure 1 - Figure 7 An adjustment mechanism 6 is also provided inside the second fence plate 22. The adjustment mechanism 6 is used to assist the baffle 5 in automatically opening and closing the discharge port 33. The adjustment mechanism 6 includes a guide post 61 and a spring 62. The guide post 61 is a cylindrical metal rod, which is fixedly installed on the inner wall or bottom wall of the second fence plate 22 along the sliding direction of the baffle 5. Both ends are fixed to the second fence plate 22 by welding or threaded connection. The spring 62 is a compression spring or a tension spring, which is coaxially sleeved on the guide post 61. One end is fixedly connected to the inner wall of the second fence plate 22, and the other end is fixedly connected to the side wall of the baffle 5. When the spring 62 is a compression spring, the pre-compression force keeps the baffle 5 in the position of closing the discharge port 33. When the discharge port 33 is opened, the external force overcomes the elastic force of the spring 62 and pushes the baffle 5 to move. After the external force is removed, the spring 62 drives the baffle 5 to automatically reset and close the discharge port 33.

[0033] In this embodiment: During operation, the spring 62 keeps the baffle 5 in the closed feed port 33 position to prevent accidental drug leakage. During feeding, the baffle 5 is compressed by the spring 62 and the feed port 33 is opened by mechanical triggering or manual operation. After the drug has fallen, the spring 62 releases its elastic potential energy to drive the baffle 5 to automatically return to its original position and close the feed port 33.

[0034] The guide post 61 and spring 62 work together to create an elastic automatic reset mechanism for the baffle 5, solving the problems of the baffle 5 relying entirely on manual pushing and pulling, poor operational convenience, and the ease with which the discharge port 33 may remain open or not close properly due to human negligence. The guide post 61 provides precise axial support and guidance for the spring 62, ensuring that the spring 62 always deforms along a predetermined straight line during extension and retraction, preventing the baffle 5 from jamming or tilting due to lateral bending of the spring 62, and improving the straightness and reliability of the baffle 5's movement. The preload of the spring 62 keeps the baffle 5 normally closed, creating continuous sealing pressure on the discharge port 33, preventing accidental leakage, moisture absorption, or foreign object intrusion of the drug during non-feeding periods; after feeding, the spring 62 immediately drives the baffle 5 to automatically return to its original position, eliminating the need for secondary manual operation, realizing semi-automatic control of the opening and closing of the discharge port 33, reducing the labor intensity of epidemic prevention personnel, ensuring precise and controllable feeding timing, and improving the standardization and safety of isolation drug delivery operations.

[0035] Example 4: Please refer to Figure 1 - Figure 7 The second fence panel 22 also contains a feeder 7, which assists in the entry of medicine into the animal enclosure. The feeder 7 is a funnel-shaped or tubular flow guide component, made of polymer material or thin metal sheet. The upper inlet is connected to or integrally connected with the discharge port 33, and the lower outlet extends beyond the outer wall of the second fence panel 22 and faces into the animal enclosure, forming a continuous flow channel. The feeder 7 is connected to the inner wall of the second fence panel 22 by a buckle or bracket.

[0036] In this embodiment: During operation, the drug is discharged through the discharge port 33 and directly enters the upper inlet of the feeder 7. Under the guidance of the feeder 7, it is concentrated and transported to the predetermined position inside the animal house, so as to avoid the drug scattering or deviating during the falling process.

[0037] By adding a feeder 7 below the feed inlet 33, a closed-loop flow channel is constructed from the storage bin 31 to the interior of the animal shed, overcoming the problems of drugs easily scattering, bouncing off course, or failing to accurately fall into the feeding trough due to airflow when falling directly from the feed inlet 33. The tubular or funnel-shaped structure of the feeder 7 physically constrains and guides the trajectory of the falling drugs, ensuring that the drugs are accurately delivered to the target area within the animal shed along a predetermined path, improving the spatial accuracy of drug delivery, and reducing ground contamination and drug waste caused by drug landing point deviations. The lower outlet of the feeder 7 extends close to the animal shed floor or feeding trough, shortening the exposure distance of the drugs in the air, reducing the loss of powdery drugs during delivery, ensuring that animals receive sufficient medication, maintaining the cleanliness of the isolation area, and improving the overall reliability of drug delivery in the epidemic prevention and isolation device. Example 5: Please refer to Figure 1 - Figure 7The storage chamber 31 is also equipped with a spring plate 8. The spring plate 8 is a thin metal plate or a polymer elastic plate with a certain degree of elasticity. One end is slidably mounted on the side wall of the feeder 7 through a sliding connection structure. This sliding connection structure consists of a T-shaped groove opened on the side wall of the feeder 7 and a T-shaped slider set at the end of the spring plate 8, so that the end of the spring plate 8 can slide relative to the side wall of the feeder 7. The other end is fixed to the side wall or outer wall of the divider 4 by welding or bolting. The spring plate 8 is arranged at an angle in the storage chamber 31. Under normal conditions, the plate surface is in an elastic equilibrium position, and it accumulates elastic potential energy when compressed by external force.

[0038] In this embodiment: During operation, when feeding medicine, the feeder 7 is pushed outward of the second fence plate 22 by the elastic potential energy of the spring plate 8, and the lower outlet extends out of the outer wall of the fence plate and approaches the ground of the animal house or the feeding trough; after feeding is completed, the feeder 7 retracts under the action of external force, and the spring plate 8 is reset.

[0039] The divider 4 and feeder 7 are elastically connected by a spring plate 8. The elastic potential energy stored in the spring plate 8 provides the active ejection force for the feeder 7, solving the problems of the feeder 7 being fixed inside the fence panel and the excessive distance between the lower outlet and the animal shed floor, resulting in strong impact force, easy splashing and bouncing of medicine, and easy dispersion of powdered medicine in the air. When the feeder 7 is ejected under the drive of the spring plate 8, the lower outlet extends out of the outer wall of the second fence panel 22 and approaches the target feeding area, significantly shortening the medicine's falling distance and allowing the medicine to enter the feed trough or the ground in a smoother manner, reducing medicine breakage, splashing, and dust raising caused by excessive drop. The sliding setting at one end of the spring plate 8 allows the feeder 7 to have controllable relative displacement with the spring plate 8 during ejection, avoiding structural interference that may occur with rigid connection; the fixed connection between the other end and the divider 4 ensures stable anchoring of the elastic force source, so that the elastic deformation of the spring plate 8 is always in a controllable direction, improving the smoothness and reliability of the feeder 7's ejection action. This elastic pop-out design eliminates the need for external power sources such as motors and cylinders, relying solely on mechanical energy storage to achieve the extension and retraction of the feeder 7, simplifying the device structure and reducing the failure rate.

[0040] Example 6: Please refer to Figure 1 - Figure 7 The storage chamber 31 is also equipped with a sliding mechanism 9, through which the feeder 7 is slidably connected to the storage chamber 31. The sliding mechanism 9 includes a sliding groove 91 formed in the bottom wall of the storage chamber 31 and a sliding block 92 set in the bottom of the feeder 7. The sliding groove 91 is a rectangular through groove or blind groove formed in the ejection direction of the feeder 7, and its length direction is consistent with the extension and retraction direction of the second grid plate 22. The sliding block 92 is a rectangular protrusion adapted to the cross-sectional shape of the sliding groove 91, fixedly set in the bottom of the feeder 7, and slidably set in the sliding groove 91, with the two in a clearance fit.

[0041] In this embodiment: During operation, the feeder 7 is pushed by the spring plate 8 and slides directionally within the sliding groove 91 on the bottom wall of the storage bin 31 via the bottom sliding block 92, thereby achieving smooth extension and retraction relative to the storage bin 31.

[0042] The precise cooperation between the sliding groove 91 and the sliding block 92 provides clear linear motion guidance and load-bearing support for the feeder 7, overcoming the problems of skewness, swaying, or even jamming caused by uneven force or center of gravity shift during the feeder 7's ejection process. The sliding groove 91, located on the bottom wall of the storage chamber 31, directly bears the weight of the feeder 7 and the loaded drug. The sliding block 92 evenly transfers the load to the structure of the storage chamber 31, preventing excessive lateral pulling of the feeder 7 on the spring plate 8 and extending the service life of the spring plate 8. The cross-sectional adaptation design of the sliding block 92 and the sliding groove 91 restricts the lateral freedom of the feeder 7 in the horizontal plane, ensuring that the feeder 7 can only perform linear reciprocating motion in a predetermined direction, improving the trajectory accuracy of ejection and retraction, and ensuring that the lower outlet is always aligned with the target feeding area, guaranteeing the accuracy and consistency of drug delivery. The sliding mechanism 9 standardizes the motion trajectory of the feeder 7, providing a structural basis for subsequent additions of guiding, limiting, and vibration-assisted functions, and enhancing the feasibility of modular expansion of the feeding mechanism 3.

[0043] Example 7: Please refer to Figure 1 - Figure 7 A guide rod 93 is also provided inside the sliding groove 91. The guide rod 93 is a cylindrical metal rod, which is fixedly installed between the two end walls of the sliding groove 91 along the length of the sliding groove 91, and the two ends are connected to the end walls of the sliding groove 91 by welding or threaded fastening. The sliding block 92 has a circular through hole that matches the diameter of the guide rod 93, and it is slidably sleeved on the guide rod 93 through the through hole.

[0044] In this embodiment: During operation, when the sliding block 92 slides in the sliding groove 91, the guide rod 93 passes through the through hole of the sliding block 92 and provides axial guidance, so that the sliding block 92 can only move along the axial direction of the guide rod 93.

[0045] By adding a guide rod 93 within the sliding groove 91, the sliding block 92 changes from sliding against the groove wall to sliding through the rod, solving the problems of the sliding block 92 tilting, deflecting, or insufficient straightness of its movement trajectory caused by uneven bottom surface or excessive lateral clearance within the sliding groove 91. The guide rod 93 provides an independent axial reference for the sliding block 92, strictly constraining its degree of freedom along the rod axis, significantly improving the linear accuracy and repeatability of the sliding motion of the feeder 7, ensuring consistency of the exit position after multiple ejections and retractions. The guide rod 93 bears part of the radial load, reducing the wear pressure on the sidewall of the sliding groove 91; the fit between the through hole of the sliding block 92 and the cylindrical surface of the guide rod 93 can further reduce the movement resistance by using a low-friction coefficient material or adding lubrication, reducing the frictional power consumption that the spring plate 8 needs to overcome to drive the feeder 7 to eject, improving the elastic potential energy conversion efficiency, making the ejection action of the feeder 7 more responsive and agile, and improving the motion quality and durability of the sliding mechanism 9.

[0046] Example 8: Please refer to Figure 1 - Figure 7 The sliding groove 91 is also provided with protrusions 10. The protrusions 10 are hemispherical, trapezoidal or cylindrical protrusions, made of wear-resistant material and fixedly installed on the bottom wall or side wall of the sliding groove 91. They are arranged at equal or non-equal intervals along the length of the sliding groove 91, with a gap between adjacent protrusions 10. The height of the protrusions 10 is designed so that the sliding block 92 makes instantaneous point contact when it passes through, but does not hinder the continuous sliding of the sliding block 92.

[0047] In this embodiment: During operation, as the feeder 7 drives the sliding block 92 to slide in the sliding groove 91, the bottom or side surface of the sliding block 92 periodically makes instantaneous point contact with the intermittently set protrusions 10. Each contact generates a small impact, which is transmitted to the feeder 7 to cause intermittent micro-vibrations.

[0048] By intermittently setting protrusions 10 within the sliding groove 91, the horizontal sliding motion of the sliding block 92 is transformed into periodic micro-vibrations of the feeder 7. This solves the problem of bridging, clumping, or adhesion to the walls of the storage chamber 31 and feeder 7 caused by moisture, static electricity, or compression, resulting in poor feeding or even blockage. During the sliding process, the sliding block 92 periodically passes over the protrusions 10, and each instantaneous point contact generates a micro-mechanical impact. This impact is transmitted to the bottom of the feeder 7 and the connected storage chamber 31 in the form of vibration waves, causing the accumulated drug to be subjected to high-frequency micro-vibrations and maintain a loose flow state. This breaks down the adhesion and static friction between drug particles, ensuring that the drug is continuously and uniformly discharged from the feed port 33. The vibration function is triggered entirely by the sliding motion of the feeder 7 itself, without the need for additional power sources or control circuits such as vibration motors or electromagnetic vibrators. It makes full use of the inherent energy of the mechanism's movement to achieve the anti-clogging function with almost no increase in structural complexity and energy consumption, thereby improving the reliability of drug feeding and the environmental adaptability of the feeding mechanism 3 in humid and sticky drug conditions.

[0049] Example 9: Please refer to Figure 1 - Figure 7 The feeder 7 also includes a first moving mechanism 11, through which the sliding block 92 is slidably connected to the feeder 7. The first moving mechanism 11 includes a first moving groove 111 formed in the bottom wall of the feeder 7, a first moving block 112 formed in the top of the sliding block 92, and a first limiting rod 113 formed within the first moving groove 111. The first moving groove 111 is a rectangular groove formed along the sliding direction of the sliding block 92, formed within the bottom wall of the feeder 7. The first moving block 112 is a rectangular protrusion adapted to the cross-sectional shape of the first moving groove 111, fixedly formed in the top of the sliding block 92, and slidably formed within the first moving groove 111. The first limiting rod 113 is a cylindrical metal rod, fixedly formed along the length of the first moving groove 111 between its two end walls. The first moving block 112 has a circular through hole and is slidably fitted onto the first limiting rod 113.

[0050] In this embodiment: During operation, while the sliding block 92 slides in the sliding groove 91, the top first moving block 112 slides synchronously in the first moving groove 111 on the bottom wall of the feeder 7. The first limiting rod 113 provides axial guidance and limitation for the first moving block 112, so that a stable and controllable sliding connection is formed between the sliding block 92 and the feeder 7.

[0051] A first moving mechanism 11 is added inside the feeder 7 to transform the direct rigid connection or simple contact between the sliding block 92 and the feeder 7 into a precision sliding connection with independent guidance and limiting. This overcomes the problem of increased wear, stress concentration, and even structural loosening caused by the impact and vibration of the protrusion 10 when the sliding block 92 directly pushes the feeder 7. The matching cooperation between the first moving groove 111 and the first moving block 112 provides an additional lateral constraint surface between the sliding block 92 and the feeder 7, increasing the contact guiding area. This ensures that the feeder 7 can maintain a stable connection with the sliding block 92 even when subjected to the impact and vibration of the protrusion 10, preventing the feeder 7 from twisting or laterally misaligning relative to the sliding block 92. The first limiting rod 113 further provides an axial reference for the first moving block 112, ensuring that the driving force transmitted from the sliding block 92 to the feeder 7 is always in a predetermined direction, improving the accuracy and efficiency of force transmission. This layered sliding design combines the external guide (sliding groove 91) of the sliding block 92 with the internal guide (first moving groove 111) of the feeder 7 to form a dual guiding mechanism, which improves the overall stability and impact resistance of the feeder 7, extends the service life of the connection between the sliding block 92 and the feeder 7, and ensures the long-term reliable operation of the feeder 7 under frequent pop-out and vibration conditions.

[0052] Example 10: Please refer to Figure 1 - Figure 7 The feeder 7 also includes a second moving mechanism 12, through which the spring plate 8 is slidably connected to the feeder 7. The second moving mechanism 12 includes a second moving groove 121 formed in the side wall of the feeder 7, a second moving block 122 disposed within the second moving groove 121, and a second limiting rod 123 disposed within the second moving groove 121. The second moving groove 121 is a rectangular groove formed along the sliding direction of the spring plate 8, located within the side wall of the feeder 7. The second moving block 122 is a rectangular protrusion adapted to the cross-sectional shape of the second moving groove 121, slidably disposed within the second moving groove 121. One end of the spring plate 8 near the feeder 7 is fixed to the second moving block 122 by welding or bolts. The second limiting rod 123 is a cylindrical metal rod fixedly disposed between the two end walls of the second moving groove 121 along its length. The second moving block 122 has a circular through hole and is slidably fitted onto the second limiting rod 123.

[0053] In this embodiment: During operation, when the feeder 7 slides relative to the storage bin 31 under the drive of the sliding block 92, the spring plate 8 slides in the second moving groove 121 through the second moving block 122 to achieve relative movement with the feeder 7. The second limiting rod 123 provides axial guidance for the second moving block 122 to ensure that the end of the spring plate 8 always moves along the predetermined trajectory.

[0054] A second moving mechanism 12 is provided on the side wall of the feeder 7 to create a precisely guided sliding connection interface between the spring plate 8 and the feeder 7. This solves the problem of loosening of the sliding fit, skewness of the spring plate 8, or even inaccurate transmission direction of elastic force when one end of the spring plate 8 is directly slidably set on the side wall of the feeder 7 due to wear of the contact surface, increased gap, or vibration impact. The matching cooperation between the second moving block 122 and the second moving groove 121 provides a regular rectangular guide space for the end of the spring plate 8, restricting the degree of freedom of the end of the spring plate 8 other than the sliding direction. This ensures that the spring plate 8 always moves along a predetermined straight trajectory during elastic deformation and reset, avoiding lateral bending or torsion of the spring plate 8 due to uneven force, and ensuring the concentrated transmission of elastic potential energy in the direction that pushes the feeder 7 out. The second limiting rod 123 further provides axial support and guidance for the second moving block 122, making the sliding of the end of the spring plate 8 in the second moving groove 121 more stable and smooth, reducing frictional resistance and wear rate. This design enables the elastic driving action of the spring plate 8 and the linear ejection motion of the feeder 7 to form a highly coordinated linkage. Even if the feeder 7 is frequently vibrated by the bump 10, the spring plate 8 can still maintain a stable connection with the feeder 7 through the second moving mechanism 12, continuously providing a reliable ejection driving force, improving the repeatability of the ejection action of the feeder 7 and the structural reliability of the feeding mechanism 3 under dynamic working conditions.
