Description

Technical Field

[0001] This utility model relates to the field of stirring components, and in particular to a stirrer for preparing oral vaccine solutions in livestock and poultry farms. Background Technology

[0002] In the prevention and control of coccidiosis in chickens, the immunization effect of coccidiosis vaccines is highly dependent on the immunization method. Drinking water immunization has become the mainstream method due to its ease of operation, but its effectiveness is directly affected by the uniformity of the dispersion of the suspending agent. Therefore, the applicant has developed a dedicated coccidiosis vaccine suspending agent and supporting preparation equipment (see Chinese patents CN116531497A and CN220425174U). Specifically, for small-scale farms without stirring devices, a manual stirring method using a strainer is proposed, which can achieve rapid preparation of small amounts of suspending solution.

[0003] However, in large-scale waterline immunization scenarios, the large number of chickens requiring immunization necessitates the preparation of hundreds of liters of suspension. Continuing to use a strainer for stirring not only drastically increases labor intensity but also makes it difficult to ensure uniform dispersion of the large volume of liquid, potentially leading to uneven vaccine distribution and reduced immunization efficacy. While specialized stirring equipment could solve this problem, coccidiosis vaccines only need to be administered once per breeding cycle, resulting in low utilization of dedicated equipment and making cost-effectiveness impractical.

[0004] It is worth noting that abandoned IBC (Integrated Circuit Holder) containers are commonly found in farms. These containers have openings such as feed inlets and filling outlets, and can be used directly as containers for preparing suspension aids, meeting basic needs such as adding water, feeding, and discharging. However, the height of these containers typically exceeds 1 meter, making it difficult to effectively stir the suspension aid deposited at the bottom manually using a strainer. This leads to clumping and insufficient dispersion of the suspension aid. Therefore, there is an urgent need to develop a lightweight stirring solution that adapts to the structure of IBC containers and can quickly and uniformly prepare large volumes of suspension aids.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] The following is in conjunction with the appendix Figures 1 to 5 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0041] A stirrer for preparing oral vaccine solutions in livestock and poultry farms, used to stir the solution in container 9, includes a stirring shaft 1, several stirring components 4 and a support assembly 5;

[0042] The support assembly 5 is installed at the bottom end of the stirring shaft 1, and the support assembly 5 is used to abut against the bottom of the inner cavity of the container 9;

[0043] Several of the stirring elements 4 are installed at intervals on the stirring shaft 1, and at least one of the stirring elements 4 is a shearing stirring element 41.

[0044] The stirring shaft 1 refers to the rod-shaped component that transmits rotational power. It can be made of stainless steel tubing, and its length can be adjusted according to the container height. The support assembly 5 refers to the positioning structure located at the bottom of the stirring shaft 1. It can be implemented using a support plate structure with self-lubricating bearings to reduce the swaying of the stirring shaft end and to prevent wear on the container bottom caused by contact only at the end fulcrum of the stirring shaft 1. The shearing agitator 41 refers to a stirring unit with a crushing function. It can be implemented using a disc structure with staggered teeth to break up agglomerated suspending agent particles.

[0045] Specifically, the existing drive device 8 (e.g., a handheld electric drill) is connected to the top of the stirring shaft 1 via a fastening assembly, transmitting rotational power to the stirring shaft 1. The support assembly 5 contacts the bottom of the container 9 to form a stable support point. Multiple layers of stirring components 4 are distributed along the axial direction of the stirring shaft 1, forming stirring zones covering different liquid layers. The shearing stirring component 41 generates shearing force through high-speed rotation, achieving shearing and dispersion of the suspending agent clumps and mixing of the suspension. The upper and lower fixed points ensure the stability of the stirring shaft 1 during high-speed rotation, preventing uneven mixing caused by shaft oscillation. The spacing of the stirring components 4 ensures axial circulation of the liquid, eliminating suspending agent deposition at the bottom of the container.

[0046] Compared to existing technologies, traditional manual stirring can only act on the liquid surface and cannot create three-dimensional flow. Stirring with a strainer has blind spots, and the stirring force is limited by human effort. This invention achieves uniform stirring of the entire suspension solution across a large volume, significantly reducing the intensity of manual operation. The support component 5 forms a stable support point by contacting the bottom of the container 9, effectively suppressing vibration of the stirring shaft 1 and ensuring stability during high-speed operation. The shearing stirring component 41 specifically addresses the problem of suspending agent particle agglomeration, and the multi-layer stirring structure forms axial circulating flow, eliminating bottom sedimentation. The overall solution is adaptable to the structure of abandoned ton containers in aquaculture farms, allowing for quick installation without container modification. Furthermore, existing drive equipment 8 in aquaculture farms can be reused.

[0047] Furthermore, the shearing and stirring component 41 includes a shearing hub, a dispersing disc 412, a plurality of upper shearing teeth 413 and a plurality of lower shearing teeth 414;

[0048] The shearing hub is integrally provided in the middle of the dispersion disk 412, and the shearing hub is sleeved on the stirring shaft 1;

[0049] The outer edge of the dispersion disk 412 is provided with a plurality of upper shear teeth 413 at equal intervals, and the lower shear teeth 414 are disposed between two adjacent upper shear teeth 413. The upper shear teeth 413 extend upward and the lower shear teeth 414 extend downward.

[0050] It is a bushing structure that fits onto the stirring shaft 1. Specifically, it can be installed on the stirring shaft 1 using an interference fit or other assembly structure to achieve synchronous movement between the stirring component 4 and the rotating shaft. The dispersing disc 412 is a disc structure that supports the dispersing teeth. Specifically, it can be manufactured using a stamping process. The integrally formed shearing hub enhances the structural rigidity to resist the centrifugal force generated by high-speed rotation. The upper shearing teeth 413 and the lower shearing teeth 414 are shearing teeth that extend upward and downward, respectively. Specifically, they can be made by welding metal sheets to the edge of the dispersing disc 412. The upper shearing teeth 413 and the lower shearing teeth 414 are arranged alternately to form a three-dimensional interlaced shearing structure.

[0051] Specifically, when the stirring shaft 1 drives the shearing and stirring component 41 to rotate, the synchronous rotation of the shearing hub and the stirring shaft 1 ensures efficient power transmission. The dispersion disk 412 maintains structural stability during high-speed rotation, preventing deformation due to centrifugal force. The upper shearing teeth 413 apply an upward shearing force to the liquid during rotation, while the lower shearing teeth 414 generate a downward reverse shearing force. The two opposing fluid forces interact to form vortices between adjacent dispersion teeth. This bidirectional shearing action causes the suspending agent particles to be subjected to mechanical impact in both the vertical and horizontal directions simultaneously, tearing the agglomerated structure in multiple directions. The alternating upper and lower dispersion teeth form a continuously varying shear gradient in the circumferential direction, promoting turbulent diffusion of the liquid in the radial direction, achieving a uniform distribution of the suspending agent particles in three-dimensional space.

[0052] Furthermore, the upper shear tooth 413 and the lower shear tooth 414 are blades with a parallelogram cross-section.

[0053] The edges of the parallelogram shear teeth form an angle α with the dispersion disk 412, further improving the shearing effect.

[0054] Furthermore, the stirring element 4 located at the bottom is an axial stirring element 42;

[0055] The axial stirring component 42 includes a stirring hub 422 and a plurality of axial stirring blades 421. The stirring hub 422 is sleeved on the stirring shaft 1, and the plurality of axial stirring blades 421 are spaced apart on the outer edge of the stirring hub 422. The axial stirring blades 421 are inclined in the vertical direction.

[0056] The axial stirring element 42 refers to the stirring element installed at the lowest end of the stirring shaft 1 (excluding the support assembly at the bottom of the stirring shaft). It is connected to the stirring shaft 1 via the stirring hub 422 and is used to enhance fluid turbulence in the bottom region of the container. The stirring hub 422 is the central connecting component of the axial stirring element 42. Specifically, it can be a ring-shaped sleeve structure, coaxially fixed to the stirring shaft 1 via a keyway or set screw, used to transmit rotational power and support the axial stirring blades 421. The axial stirring blades 421 refer to the blade structure distributed circumferentially along the stirring hub 422. Specifically, they can be formed by bending rectangular, trapezoidal, or fan-shaped thin plates. The blade plane forms an inclined angle with the axis of the stirring shaft 1, used to generate vertical (axial) fluid shear force during rotation.

[0057] Specifically, when the stirring shaft 1 drives the axial stirring element 42 to rotate, the inclined axial stirring blades 421 generate a vertical component force in the horizontal rotation direction, pushing the fluid at the bottom to move upward. A continuous pressure gradient is formed between adjacent axial stirring blades 421, causing the suspending agent particles deposited at the bottom of the container to be entrained into the stirring area. The tilt angle of the axial stirring blades 421 can adjust the fluid lifting speed and prevent particles from re-settling. The rigid connection between the stirring hub 422 and the stirring shaft 1 ensures efficient power transmission and prevents energy loss caused by blade oscillation.

[0058] Compared to existing technologies, traditional manual strainer stirring only creates localized eddies near the liquid surface and cannot effectively act on the bottom of the container. The horizontal circulation generated by conventional radial stirring blades easily creates dead zones at the bottom of deep containers, leading to continuous deposition of the suspending agent. This solution, through the inclined structure design of the axial stirring blades, increases vertical fluid movement while maintaining horizontal stirring capability, forming a circulating flow path from bottom to top. Through the above technical solution, this application effectively solves the clumping problem caused by suspending agent deposition at the bottom of the container, achieving continuous suspension mixing by directional lifting of the bottom material, ensuring the uniform dispersion of large-volume suspensions in large-scale immunization scenarios.

[0059] Furthermore, the axial stirring blade 421 includes a connecting end 4211, a lower blade end 4212, an upper blade end 4213, and an outer blade end 4214;

[0060] The connecting end 4211 is inclinedly fixed to the outer edge of the stirring hub 422. One end of the lower end 4212 of the blade is connected to the lower end of the connecting end 4211. One end of the upper end 4213 of the blade is connected to the upper end of the connecting end 4211. The other end of the lower end 4212 of the blade is connected to the lower end of the outer end 4214 of the blade. The other end of the upper end 4213 of the blade is connected to the upper end of the outer end 4214 of the blade.

[0061] The connecting end 4211 refers to the connecting structure that forms an inclined angle with the outer edge of the stirring hub 422. This can be achieved through welding. This inclined angle causes the stirring blade to generate vertical fluid shear force during rotation. The lower blade end 4212 refers to the blade edge extending outward from the lower part of the connecting end 4211. This can be achieved using an arc-shaped curved surface transition structure, used to guide the liquid downward flow and impact the bottom sediment. The upper blade end 4213 refers to the blade edge extending outward from the upper part of the connecting end 4211. This can be achieved using a curved surface structure symmetrical to the lower blade end 4212, used to generate upward liquid backflow. The outer blade end 4214 refers to the closed structure connecting the outer edges of the lower blade end 4212 and the upper blade end 4213. This can be achieved using an integrally formed arc-shaped structure, which enhances the blade structure strength and generates a radial centrifugal force field and an axial circulating fluid dynamic field by forming a continuous curved surface.

[0062] To further explain, the connecting end 4211 is fixed to the stirring hub 422 at an angle, causing the axial stirring blade 421 to exhibit a spatial torsion shape. When the stirring shaft 1 drives the stirring hub 422 to rotate, the lower end 4212 of the blades of the axial stirring blade 421 cuts into the bottom region of the liquid, disturbing the deposited suspending agent particles. As the axial stirring component 42 rotates as a whole, the blades rise along the curved surface of the axial stirring blade 421, causing the liquid to form an upward flow and preventing secondary sedimentation of the particles. This combined axial and radial flow pattern can cover the space from the bottom to the middle of the container, effectively breaking up the agglomeration of the suspending agent particles.

[0063] like Figure 4 The diagram shows a specific embodiment of the axial agitator 42, the purpose of which is to allow the liquid at the bottom of the container 9 to flow axially upwards, so that the agitator 4 in the middle can provide sufficient shear to quickly hydrate the suspending agent particles. Moreover, since some of the suspending agent may settle to the bottom, if it were not in the form of axial flow but radial flow, the suspending agent at the bottom of the container might not be easily agitated and might settle to the bottom, affecting the hydration process.

[0064] Furthermore, the support assembly 5 includes a fisheye bearing inner ring 51, a fisheye bearing outer ring 52, a support plate 53, and an anti-slip pad 54;

[0065] The inner ring 51 of the fisheye bearing is located on the stirring shaft 1, the outer ring 52 of the fisheye bearing is located on the top of the support plate 53, the anti-slip pad 54 is located on the bottom of the support plate 53, and the inner ring 51 of the fisheye bearing is rotatably connected to the outer ring 52 of the fisheye bearing.

[0066] A fisheye bearing is a bearing with a spherical contact structure, specifically a spherical plain bearing or a spherical roller bearing. The inner ring 51 of the fisheye bearing is fixedly connected to the end of the stirring shaft 1. The outer ring 52 of the fisheye bearing is equipped with a support plate 53, specifically the outer ring 52 and the support plate 53 are integrally formed. The inner ring 51 and the outer ring 52 of the fisheye bearing achieve multi-angle deflection through the spherical contact surface. The support plate 53 is a flat plate structure that contacts the bottom of the container 9, specifically made of round or square steel plate, which increases the contact area to distribute the axial load transmitted by the stirring shaft. The anti-slip pad 54 is an elastic pad with a high coefficient of friction, specifically molded from rubber or silicone material, with a thickness of 3-8 mm. It is fixed to the bottom surface of the support plate by adhesive or snap-fit ​​methods to prevent the support assembly from sliding at the bottom of the container.

[0067] Specifically, the inner ring 51 of the fisheye bearing is rigidly connected to the end of the stirring shaft 1. When the stirring shaft 1 rotates, the outer ring 52 of the fisheye bearing and the support plate 53 remain stationary, while the inner ring 51 rotates synchronously with the stirring shaft. The spherical contact surface allows the stirring shaft 1 to deflect within a certain angle range. When the anti-slip pad 54 on the bottom surface of the support plate 53 contacts the bottom of the container 9, it uses elastic deformation to conform to the uneven area of ​​the bottom surface of the container 9, while simultaneously using frictional resistance to counteract the tangential force generated by the rotation of the stirring shaft 1. When the bottom surface of the container is tilted or locally concave, the spherical contact structure of the fisheye bearing can adaptively adjust the angle of the stirring shaft axis, preventing vibration caused by the slippage of the support point from being transmitted to the stirring shaft.

[0068] Furthermore, it also includes a seated bearing assembly 2, which is mounted on the stirring shaft 1 and is used for installation and connection with the container 9;

[0069] The mounted bearing assembly 2 includes a bearing body, a bearing housing, and several catches;

[0070] The bearing body is sleeved on the stirring shaft 1, and the bearing seat is rotatably connected to the outer side of the bearing body;

[0071] Several of the aforementioned hooks are provided on the outside of the bearing housing, and the bearing housing is installed and connected to the opening of the container through the hooks.

[0072] The bearing body is fitted onto the upper middle part of the stirring shaft 1. The bearing seat is connected to the bearing body via a rotating joint, allowing the stirring shaft 1 to rotate freely within the bearing seat. Hooks are arranged in a circumferential array on the outer periphery of the bearing seat. When the bearing seat is pressed down to the container opening, the barbs of the hooks open outwards under elastic action. After the bearing seat is fully embedded in the opening, the hooks spring back and fasten to the flange structure at the edge of the container opening. During this process, the elastic deformation of the hooks can adapt to the flanges of containers with different thicknesses. The tilt angle design of the barbs ensures that a downward component force is generated when the stirring shaft rotates, further enhancing the engagement strength between the hooks and the container edge.

[0073] Furthermore, the seated bearing assembly 2 is adjustablely mounted on the stirring shaft 1.

[0074] When the stirring mechanism needs to adapt to containers of different heights, the operator can first release the axial fixation between the bearing assembly 2 and the stirring shaft 1. For example, in a threaded fit structure, the bearing seat can be rotated to move up and down along the threaded section of the stirring shaft. When it reaches the position that matches the current container opening height, the locking nut can be tightened for axial positioning. In a clamp-type structure, after loosening the clamp bolts, the bearing seat can be slid directly to the target position and then tightened. After adjustment, the bearing assembly 2 maintains a stable connection with the container opening and ensures that the depth of the lower end of the stirring shaft 1 extending into the container matches the total height of the container, ensuring that the bottom support assembly 5 can effectively contact the bottom surface of the container cavity.

[0075] Furthermore, the distance between the bottom of the stirring element 4 located at the lowest point and the bottom of the stirring shaft 1 is less than 5 cm;

[0076] The distance between the topmost stirring element 4 and the top of the stirring shaft 1 is greater than 10cm.

[0077] By limiting the distance between the bottommost stirring element 4 and the bottom of the stirring shaft 1, a vortex region close to the bottom of the container is formed when the stirring shaft 1 rotates, directly impacting the deposited suspending agent particles and preventing agglomeration. Furthermore, effective stirring is achieved even with small amounts of solution. Simultaneously, by limiting the distance between the topmost stirring element 4 and the top of the stirring shaft 1, a stable circulating flow field is formed in the upper part of the container, ensuring uniform diffusion of the suspending agent in the liquid surface area. This spatial arrangement allows the stirring action to cover the entire height from the bottom to the top of the container. Especially in ton containers with a height exceeding 1 meter, the synergistic effect of strong bottom shearing and extended upper stirring creates a three-dimensional stirring effect without dead zones.

[0078] Furthermore, it also includes a coupling 3, which is installed at the top end of the stirring shaft 1 and is used to connect to the drive end of the drive device 8. The coupling 3 refers to a power transmission connector, which can be implemented using a quick-release universal coupling to facilitate quick docking with the external drive device 8.

[0079] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
