Description

Technical Field

[0001] This invention belongs to the technical field of blood collection equipment for livestock breeding, and specifically relates to a newborn calf blood collection auxiliary shaking device. Background Technology

[0002] In livestock breeding and cattle disease detection, breeding and selection, blood sample collection from newborn cattle is a routine and important operation. Due to their small size and thin blood vessels, newborn cattle are prone to struggling during blood collection due to tension, which can lead to poor blood flow. This not only affects the efficiency of blood collection, but may also result in insufficient blood sample volume and reduced sample quality due to incomplete blood collection, thus affecting the subsequent test and analysis results.

[0003] According to the public announcement (CN104337587A), a "foldable portable mobile animal restraint frame" was disclosed. This restraint frame is easy to carry and operate, overcoming the difficulty of restraining large animals in mountainous rural areas. It brings convenience to animal breeders and veterinary staff. After disassembly and folding, the restraint frame can be loaded into tricycles, pickup trucks, minivans, agricultural vehicles, etc., and can be installed and removed on the spot without delaying the effect of diagnosis and treatment. However, there are many technical defects in practical applications: First, it can only fix the body of the calf and cannot assist the blood flow to the blood collection site in any way. It cannot solve the problem of vasoconstriction caused by the tension and struggle of newborn calves, and the phenomenon of incomplete blood collection is common. Second, the manual touching and forced fixation methods can easily cause strong stress reactions in newborn calves, which will not only further aggravate vasoconstriction, making blood collection more difficult, but may also have adverse effects on the health of newborn calves, and cannot meet the blood collection operation needs of newborn calves.

[0004] To address the aforementioned issues, this application proposes a newborn calf blood collection auxiliary device. Summary of the Invention

[0005] This invention addresses the technical problem that traditional devices only have a single restraint function, lack blood collection assistance, and have no structural design adapted to newborn calves, thus failing to meet the blood collection operation requirements of newborn calves. It provides a newborn calves blood collection auxiliary shaking device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a newborn calf blood collection auxiliary shaking device, comprising a base and an inclined platform with anti-slip protrusions installed at an angle on one side of the base; Above the base is a calf riding platform for calves to ride on. The surface of the calf riding platform has a concave pad that fits the contour of the calf's abdomen and neck. When blood is drawn, the calf riding platform moves back and forth in a small, regular motion above the base to simulate the calf's natural activity state and promote blood flow to the blood collection site. The calf riding platform is symmetrically equipped with flexible straps on both sides. The flexible straps can be adjusted and connected to both sides of the calf riding platform to accommodate the blood collection fixation needs of newborn calves of different sizes. A heating pad is detachably installed on the calf riding platform. The heating pad is placed around the neck of the corresponding newborn calf to appropriately increase the local temperature of the blood collection site, achieve vasodilation, and further promote blood flow. The surface of the heating pad has a needle groove for inserting the blood collection tool. The calf riding platform is fixedly equipped with support rods, and a multi-degree-of-freedom light is detachably installed at the top of the support rods. The illumination position of the multi-degree-of-freedom light corresponds to the position of the blood collection site on the neck of the newborn calf, which is used to provide the operator with a clear blood collection field of vision, making it easier to quickly find the blood collection vessel and improve blood collection efficiency.

[0007] As a preferred embodiment of the newborn calf blood collection auxiliary calf shaking device of the present invention, the base is provided with a support groove plate inside, and two sliders are symmetrically slidably arranged inside the support groove plate. Vertical sliding sleeves are symmetrically installed at both ends of the support groove plate, and vertical sliding rods are slidably connected inside the vertical sliding sleeves. The top of each of the two vertical sliding rods is integrally formed with a sliding column. Fixed sliding seats are symmetrically installed on the bottom surface of the calf riding platform. The fixed sliding seats have strip grooves inside. The two vertical sliding rods are slidably connected to the strip grooves inside the two fixed sliding seats through the sliding columns at their top ends. The bottom side of each of the two vertical sliding rods is hinged with a hinge rod, and the other end of the two hinge rods is respectively hinged to the two sliders. During blood collection, the two vertical sliding rods alternately reciprocate, realizing a small-amplitude reciprocating regular shaking in the back-and-forth direction during the blood collection process.

[0009] As a preferred embodiment of the newborn calf blood collection auxiliary shaking device of the present invention, the surfaces of the two sliders are slidably connected to limit rods, the limit rods are fixedly installed in the support bar groove plate, and the outer surface of the limit rods is fitted with springs for auxiliary reset, one end of the spring abuts against the surface of the slider, and the other end of the spring abuts against the inner side wall of the support bar groove plate.

[0010] As a preferred embodiment of the newborn calf blood collection auxiliary shaking device of the present invention, the surface of the toothed plate is provided with a relief groove adapted to the limiting slide rod along its own length direction.

[0011] In a preferred embodiment of the newborn calf blood collection auxiliary shaking device of the present invention, a limiting slider is fixedly installed on the surface of the toothed plate along its own length direction. The inner sidewall of the support bar groove plate is provided with a guide groove adapted to the limiting slider. The toothed plate is horizontally slidably connected to the support bar groove plate through the limiting slider and the guide groove. A vertical guide bar is vertically installed on the inner sidewall of the vertical sleeve. A vertical groove adapted to the vertical guide bar is provided on the surface of the vertical slide rod. The vertical slide rod is vertically slidably connected to the vertical sleeve through the vertical guide bar and the vertical groove.

[0012] As a preferred embodiment of the newborn calf blood collection auxiliary shaking device of the present invention, a retainer is fixedly installed on the same side of the bottom of the two vertical sliding sleeves, and the same transmission shaft is rotatably connected between the two retainers. Gears are fixed on the outer surfaces of both ends of the transmission shaft, and gear rings are fixed on the same side of the two vertical sliding sleeves. The gear rings mesh with gears. A rotating shaft is fixed on one side of the bottom of the two vertical sliding sleeves, and the other end of the two rotating shafts is rotatably connected to the inner side wall of the base. During blood collection, the two vertical sliding sleeves swing back and forth synchronously around the rotating shafts, realizing small-amplitude reciprocating regular shaking in the left and right direction during the blood collection process.

[0013] As a preferred embodiment of the newborn calf blood collection auxiliary shaking device of the present invention, a worm is installed at the output shaft end of the forward and reverse motor, and a U-shaped mounting bracket is rotatably connected to the end of the worm away from the forward and reverse motor. The U-shaped mounting bracket is fixedly connected to the support bar groove plate, and a worm wheel is fixedly installed on the surface of the transmission shaft, with the worm meshing on the surface of the worm wheel.

[0014] As a preferred embodiment of the newborn calf blood collection auxiliary calf shaking device of the present invention, the two vertical sliding sleeves are fixed with limiting shafts on their opposite sides, and two arc-shaped limiting shaft frames are symmetrically installed on the surface of the base. The surface of the arc-shaped limiting shaft frames is provided with arc-shaped grooves, and the limiting shafts are slidably connected in the arc-shaped grooves.

[0015] As a preferred embodiment of the newborn calf blood collection auxiliary shaking device of the present invention, the irradiation end of the multi-degree-of-freedom lighting lamp is integrally formed with a horn-shaped reflector, and multiple shadow reduction lamps are installed in a ring on the inner surface of the reflector.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This equipment is designed specifically for newborn calves, which are small in size and have thin blood vessels. It features a straddle-style calf platform with a concave pad that conforms to the contours of the calf's abdomen and neck, allowing the blood collection site to stretch naturally and avoiding blood vessel compression. At the same time, the transmission structure enables the calf platform to move back and forth in small, rhythmic motions, accurately simulating the natural activity of the calf and actively promoting blood flow to the neck collection site. Combined with a heating pad around the neck, the blood collection site is precisely heated locally, and the heat effect expands the blood vessels and increases the diameter of the vessels. This creates a dual auxiliary effect of swaying to promote flow and heating to expand the vessels, completely overcoming the problems of slow blood flow and vascular constriction in traditional blood collection. This significantly improves the blood sample volume compliance rate and ensures the accuracy of subsequent test results. The equipment uses an inclined platform with anti-slip protrusions to guide the cattle, conforming to the walking habits of newborn calves and avoiding stress caused by forced driving. Flexible and adjustable straps replace the traditional rigid fixation method, which not only avoids squeezing damage to the delicate bodies of newborn calves, but also allows for flexible adjustment of tightness according to the different sizes and ages of newborn calves, ensuring the fixation effect while minimizing the feeling of restraint. The shaking mechanism, through symmetrical transmission and precise limit design, ensures that the calves' shaking on the platform is stable and the trajectory is controllable. The arc-shaped limit structure strictly limits the shaking amplitude, avoiding excessive shaking that may cause the cattle to resist. At the same time, the equipment has a built-in pressure sensor that can monitor the strength of the cattle's struggle in real time. When it exceeds the preset threshold, it automatically adjusts the motor speed to slow down or stop. In conjunction with the needle groove on the heating pad, it provides precise piercing positioning for the blood collection tool, avoiding accidental puncture and injury to the cattle. All these measures reduce the stress response of cattle during the blood collection process, ensuring blood collection safety and the health of the cattle. This equipment uses a single forward and reverse motor as its power source to synchronously drive the forward and backward, left and right swaying mechanism, realizing automated and regular swaying. It replaces the traditional manual restraint and auxiliary swaying operation, significantly reducing manpower input compared to the traditional method, and effectively shortening the blood collection time for a single newborn calf, thus improving the overall blood collection efficiency of large-scale farms. The equipment's flexible straps are adjustable, and the swaying parameters can be precisely controlled to adapt to the blood collection needs of newborn calves of different sizes and ages, achieving multi-purpose functionality. There is no need to configure separate equipment for different sizes of cattle, reducing the overall investment cost of breeding equipment. At the same time, the design of the inclined platform, heating pad, lighting, and other structures further simplifies the blood collection operation process, allowing operators to complete blood collection quickly and accurately, improving operational efficiency. The equipment's swaying transmission system employs precise transmission structures such as gear meshing and worm gears, combined with a symmetrical design of double sliders and double vertical slide bars. This ensures uniform force distribution during transmission, guaranteeing accurate and smooth motion transmission. Simultaneously, a double-guided limiting structure is formed by components such as limit slide bars, limit sliders, and vertical guide bars, strictly limiting the movement trajectory of each transmission component to avoid problems such as skewing, jamming, and tooth breakage. Combined with the elastic buffering and reset effect of springs, this effectively reduces impact forces and component wear during transmission, lowering equipment energy consumption. The self-locking property of the worm gear transmission also prevents accidental swaying due to external forces, improving operational safety. Furthermore, functional components such as heating pads and lighting lamps are designed to be detachable, facilitating daily cleaning, disinfection, maintenance, and replacement, meeting the hygiene and disease prevention requirements of livestock farming. Core components such as support groove plates and bases are made of rigid materials, ensuring the overall structural strength of the equipment and significantly extending its service life and practical value.

[0019] 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.

[0020] Example: Figures 1-14As shown, this invention provides a technical solution: a newborn calf blood collection auxiliary calf shaking device, including a base 1 and an inclined platform 2 with anti-slip protrusions installed on one side of the base 1. Above the base 1 is a calf riding platform 3 for the calf to mount. The surface of the calf riding platform 3 has concave pads adapted to the contours of the calf's abdomen and neck. During blood collection, the calf riding platform 3 moves in a small, rhythmic back-and-forth motion above the base 1, simulating the calf's natural activity and promoting blood flow to the collection site. The inclined structure conforms to the walking habits of newborn calves, avoiding stress caused by forced movement and preventing... The slippery bumps prevent cattle from slipping and falling, improving the safety and comfort of the guidance process. No multiple people are needed for assistance, reducing manpower. The concave pads conform to the contours of the calf's abdomen and neck, allowing for a natural fit, replacing traditional rigid restraint methods and significantly reducing resistance and stress. The straddle-style structure allows the blood collection site (neck) of the newborn calf to stretch naturally, avoiding blood vessel compression caused by a cramped posture, thus facilitating the blood collection operation. The calf's straddle platform features small, rhythmic back-and-forth swaying motions, simulating the calf's natural activity and overcoming the slow blood flow caused by a static posture during blood collection. The device actively promotes blood flow to the neck sampling site, addressing the core issues of thin blood vessels, poor blood flow, and incomplete blood collection at their root, thus improving the blood sample volume compliance rate. The calf riding platform 3 is symmetrically equipped with flexible straps 4 on both sides. These straps 4 are adjustable and connect to both sides of the platform, adapting to the blood collection and fixation needs of newborn calves of different sizes. The adjustable flexible straps 4 are made of flexible material to avoid squeezing or damaging the delicate bodies of newborn calves. The symmetrical adjustable structure on both sides adapts to the fixation needs of newborn calves of different sizes and ages, achieving equipment versatility and eliminating the need for separate systems for different sizes of cattle. The equipment configuration reduces the investment cost of breeding equipment. The adjustable straps allow for flexible control of the tightness of the fixation, minimizing the feeling of restraint and reducing stress response while ensuring that the cattle do not struggle or shift. A heating pad 5 is detachably installed on the calf riding platform 3. The heating pad 5 is placed around the neck of the corresponding newborn calf to appropriately increase the local temperature of the blood collection site, achieve vasodilation, and further promote blood flow. The surface of the heating pad 5 has a needle groove 40 for inserting the blood collection tool. The detachable design facilitates the cleaning, disinfection, and replacement of the heating pad 5, meeting the hygiene and epidemic prevention requirements of animal husbandry.The neck-encircling mounting method enables precise local heating of the blood collection site, controlling the temperature within a suitable range. The thermal effect expands the blood vessels at the collection site, increasing their diameter. This facilitates accurate vessel location for the operator and further promotes blood flow. Combined with a shaking motion, it achieves a dual effect of promoting flow through shaking and expanding the vessel through heating. The lower needle groove 40 provides precise insertion positioning for the blood collection tool, preventing needle deviation and injury to the cattle or accidental puncture of other tissues. This improves the accuracy and safety of the blood collection operation and shortens the operation time. The surface of the calf riding platform 3 is fixedly equipped with supports. The top of the support rod 6 is detachably equipped with a multi-degree-of-freedom lighting lamp 7. The lighting lamp 7 illuminates the blood collection site on the neck of newborn calves, providing operators with a clear view of the blood collection area, facilitating quick location of the blood collection vessel, and improving blood collection efficiency. The multi-degree-of-freedom design allows for flexible adjustment of the lighting angle, height, and distance of the multi-angle lighting lamp 7, achieving comprehensive illumination of the blood collection site without blind spots. This solves the problem of insufficient lighting and poor visibility at the blood collection site in farms, making it difficult to locate blood vessels. This allows operators to quickly and accurately locate blood vessels, significantly improving blood collection efficiency.

[0021] Furthermore, the base 1 has a support groove plate 11 inside, and two sliders 15 are symmetrically slidably arranged inside the support groove plate 11. Vertical sliding sleeves 19 are symmetrically installed at both ends of the support groove plate 11. Vertical sliding rods 21 are slidably connected inside the vertical sliding sleeves 19. The top of each of the two vertical sliding rods 21 is integrally formed with a sliding column 23. The bottom surface of the calf riding platform 3 is symmetrically installed with fixed sliding seats 24. The fixed sliding seats 24 have strip grooves 25 inside. The two vertical sliding rods 21 are slidably connected to the strip grooves 25 inside the two fixed sliding seats 24 through the sliding columns 23 at their top ends. Each of the two vertical slides 16 is hinged to one side of its bottom. The other end of each of the two vertical slides 16 is hinged to one of the two sliders 15. During blood collection, the two vertical slides 21 alternately lift back and forth, achieving a small, regular back-and-forth swaying motion in the front-and-back direction. The symmetrical structure of the two sliders 15 and the two vertical slides 21 ensures uniform force distribution during transmission, avoiding the problem of tilting and irregular swaying of the calf riding platform 3 caused by unilateral force distribution. This ensures the stability of the front-and-back swaying motion and reduces stress on newborn calves caused by uneven equipment swaying. The alternating lifting motion of the two vertical slides 21 achieves a small, regular back-and-forth swaying motion of the calf riding platform 3. The movement trajectory is controllable, avoiding excessive shaking that could cause discomfort to the calf. The vertical lifting motion of the vertical slide bar 21 is converted into the forward and backward horizontal swaying of the calf riding platform 3, achieving a precise conversion of movement. The transmission process is smooth and free of jamming, ensuring the smoothness of the swaying. The sliding cooperation between the slide bar 23 and the strip groove 25 provides guidance for the swaying of the calf riding platform 3, preventing deviation during swaying and ensuring the consistency of the swaying trajectory. The flexible transmission between the horizontal sliding of the slider 15 and the vertical lifting of the vertical slide bar 21 buffers the impact force during the transmission process, avoiding component wear and abnormal noise caused by rigid transmission, while ensuring the accuracy of motion transmission. The displacement of slider 15 can be accurately converted into the lifting height of vertical slide bar 21, achieving controllability of sway amplitude. The sliding cooperation between vertical sleeve 19 and vertical slide bar 21 provides precise guidance for the vertical movement of vertical slide bar 21, avoiding deviation or jamming of vertical slide bar 21 during lifting, ensuring the stability and verticality of vertical slide bar 21 movement, and thus ensuring the stability of swaying of calf riding platform 3. It achieves precise control of small reciprocating regular swaying in the front and back direction of calf riding platform 3, ensuring the swaying flow promotion effect while improving the stability and service life of equipment transmission structure, taking into account both blood collection auxiliary effect and equipment operation reliability.

[0022] Furthermore, a mounting plate 12 is fixedly installed on one side surface of the support bar groove plate 11. A reversible motor 41 is bolted to the surface of the mounting plate 12. A gear 13 is mounted on the output shaft of the reversible motor 41. A toothed plate 14 is provided inside the support bar groove plate 11, between the two sliders 15. The gear 13 meshes with the toothed plate 14. The reversible motor 41, as a power source, can realize the forward and reverse rotation of the motor output shaft, thereby driving the reciprocating horizontal sliding of the toothed plate 14. This provides continuous and controllable power for the alternating sliding of the two sliders 15 and the alternating lifting of the two vertical slide rods 21. It eliminates the need for manual drive, achieving automated shaking, significantly reducing manpower input, and providing more precise control. It is suitable for the actual use scenarios of farms. The meshing transmission between the gear 13 and the toothed plate 14 has high transmission efficiency, precise power transmission, and strong operational stability. The rotational motion of the reversible motor 41 is precisely converted into the horizontal linear motion of the toothed plate 14, ensuring that the sliding distance and speed of the toothed plate 14 are precisely matched with the motor speed. This enables precise control of the frequency and amplitude of the calf riding platform 3's forward and backward swaying. The toothed plate 14 is positioned between the two sliders 15, allowing the reciprocating sliding of the toothed plate 14 to simultaneously drive the sliders 15 on both sides to slide alternately in opposite directions. This, in turn, enables the alternating lifting of the double vertical slide rods 21, ensuring the compactness of the transmission structure, reducing the space occupied by the transmission components, and making the internal structure of the equipment simpler. At the same time, it ensures the synchronicity and coordination of the movement of the sliders 15 on both sides, ensuring the stability of the calf riding platform 3's swaying. This allows for flexible adjustment of the frequency and amplitude of the calf riding platform 3's forward and backward swaying, adapting to the tolerance of different newborn calves. It also improves the transmission efficiency and operational stability of the equipment, while reducing the equipment's maintenance costs and energy consumption.

[0023] Furthermore, both sliders 15 are slidably connected to limit rods 17. The limit rods 17 are fixedly installed within the support groove plate 11. A spring 18 for assisting in resetting is sleeved on the outer surface of the limit rod 17. One end of the spring 18 abuts against the surface of the slider 15, and the other end abuts against the inner wall of the support groove plate 11. The limit rods 17 provide precise and rigid guidance for the horizontal sliding of the sliders 15, strictly limiting the movement trajectory of the sliders 15, preventing the sliders 15 from deflecting, rotating, or jamming during sliding, ensuring the smoothness and straightness of the sliders 15's sliding, and ensuring the regularity of the calf riding platform 3's swaying. When the toothed plate 14 drives the sliders 15 to slide... When in motion, the spring 18 is compressed or stretched, generating elastic potential energy. When the toothed plate 14 slides in the opposite direction, the elastic potential energy of the spring 18 is released, pushing the slider 15 to quickly and smoothly reset, assisting in the reciprocating sliding of the slider 15, reducing the driving load of the motor, and lowering energy consumption. The spring 18 can buffer the impact force during the sliding process of the slider 15, avoiding hard collision between the slider 15 and the inner wall of the support bar groove plate 11, reducing component wear, and extending the service life of the equipment. By using the spring 18 to achieve the auxiliary reset and buffering of the slider 15, the accuracy and stability of the forward and backward rocking mechanism transmission are ensured, while reducing equipment energy consumption and component wear, and improving the impact resistance and service life of the equipment.

[0024] Furthermore, the surface of the toothed plate 14 is provided with a relief groove 28 that matches the limiting slide rod 17 along its own length direction, so as to avoid interference or collision between the toothed plate 14 and the limiting slide rod 17 during horizontal sliding, ensuring the smoothness and smoothness of the sliding of the toothed plate 14, and ensuring the continuity and accuracy of the transmission process.

[0025] Furthermore, a limiting slider 26 is fixedly installed on the surface of the toothed plate 14 along its length. The inner wall of the support groove plate 11 has a guide groove 27 adapted to the limiting slider 26. The toothed plate 14 is horizontally slidably connected to the support groove plate 11 via the limiting slider 26 and the guide groove 27. A vertical guide bar 20 is vertically installed on the inner wall of the vertical sleeve 19. The surface of the vertical slide rod 21 has a vertical groove 22 adapted to the vertical guide bar 20. The vertical slide rod 21 is vertically slidably connected to the vertical sleeve 19 via the vertical guide bar 20 and the vertical groove 22. The cooperation between the limiting slider 26 and the guide groove 27 provides secondary guidance and limitation for the horizontal sliding of the toothed plate 14. This, along with the meshing guidance of the gear 13 and the toothed plate 14, forms a double-guide structure, further restricting the movement trajectory of the toothed plate 14 and preventing it from tilting or deviating during sliding. The meshing clearance between the gear plate 14 and the gear 13 is always uniform to prevent disengagement and improve the stability and accuracy of the transmission. The vertical guide bar 20 and the vertical slide groove 22 provide secondary guidance and limit for the vertical movement of the vertical slide rod 21. Together with the vertical slide sleeve 19 and the vertical slide rod 21, they form a double guide structure, which strictly limits the circumferential rotation of the vertical slide rod 21 and prevents it from rotating during the lifting process. This ensures that the hinge point position of the hinge rod 16 with the vertical slide rod 21 and the slider 15 remains unchanged, ensuring the accuracy of motion transmission. Through the double guide structure, the movement of the gear plate 14 and the vertical slide rod 21 is precisely limited, completely avoiding the skew, tilting and rotation of the transmission components. This ensures that the movement trajectory of each transmission component is accurate and controllable, improves the overall stability and accuracy of the transmission structure, prevents problems such as disengagement and movement jamming, and further extends the service life of the equipment.

[0026] Furthermore, retainers 39 are fixedly installed on the same side of the bottom of both vertical sliding sleeves 19. A common drive shaft 38 is rotatably connected between the two retainers 39. Gears 31 are fixed to the outer surfaces of both ends of the drive shaft 38. Gear rings 30 are fixed to the same side of both vertical sliding sleeves 19, meshing with gears 31. Rotating shafts 29 are fixed to one side of the bottom of both vertical sliding sleeves 19. The other ends of the rotating shafts 29 are rotatably connected to the inner wall of the base 1. During blood collection, the two vertical sliding sleeves 19 synchronously swing left and right around the rotating shafts 29, achieving left-right rotation during blood collection. The small, regular reciprocating oscillations to the right provide stable rotational support for the drive shaft 38, ensuring its coaxiality and preventing it from tilting or wobbling during rotation. This ensures uniform meshing clearance between the gears 31 and gear rings 30 at both ends of the drive shaft 38, enabling synchronous power transmission between the two drive shafts. It also ensures the synchronicity of the oscillations of the two vertical sliding sleeves 19, preventing uneven swaying of the calf riding platform 3 caused by excessively fast or slow swaying on one side, thus improving the stability of the swaying. The rotational motion of the drive shaft 38 is precisely converted into the axial oscillation of the vertical sliding sleeves 19, thus improving the transmission stability. With high efficiency and precise power transmission, it enables precise control of the swing angle and frequency of the vertical sliding sleeve 19, thereby achieving precise regulation of the left-right swaying amplitude and frequency of the calf riding platform 3. The hinged support of the rotating shaft 29 provides a fixed rotation fulcrum for the reciprocating swing of the vertical sliding sleeve 19, strictly limiting the swing trajectory of the vertical sliding sleeve 19 and ensuring that the vertical sliding sleeve 19 swings around a fixed axis, realizing the regular left-right swaying of the calf riding platform 3. The rotating connection method makes the swing friction of the vertical sliding sleeve 19 small, the swing smooth, reduces power loss, and improves the operating efficiency of the equipment. The vertical sliding sleeve 19 also serves as the vertical sliding rod 2. The guide component 1 also serves as a swinging component for left and right swaying, achieving structural integration of the front-to-back swaying mechanism and the left-to-right swaying mechanism. This makes the internal structure of the equipment more compact, reduces the number of parts, lowers the overall size of the equipment and manufacturing costs, while ensuring the coordination of the two swaying mechanisms. This enables precise control of the small-amplitude reciprocating regular swaying in the left and right directions of the calf riding platform 3, which, in conjunction with the front-to-back swaying, forms a compound swaying motion that is closer to the natural activity state of the calf, further enhancing the blood flow promotion effect. At the same time, the structural integration makes the equipment structure more compact, reduces manufacturing costs, and ensures the coordination and stability of the two-way swaying.

[0027] Furthermore, a worm gear 36 is mounted on the output shaft end of the reversible motor 41. A U-shaped mounting bracket 35 is rotatably connected to the end of the worm gear 36 away from the motor 41. The U-shaped mounting bracket 35 is fixedly connected to the support bar groove plate 11. A worm wheel 37 is fixedly mounted on the surface of the transmission shaft 38, and the worm gear 36 meshes with the surface of the worm wheel 37. The U-shaped mounting bracket 35 provides stable rotational support for the free end of the worm gear 36, cooperating with the output shaft of the reversible motor 41 to ensure the coaxiality of the worm gear 36, preventing skewness during rotation, ensuring uniform meshing clearance between the worm gear 36 and the worm wheel 37, and preventing tooth disengagement. The U-shaped mounting bracket 35 is fixed to the support bar groove plate 11, stabilizing the installation position of the worm gear 36 and improving the overall rigidity of the transmission structure. The meshing transmission between the worm gear 36 and the worm wheel 37 is realized. The vertical transmission of power and the reduction and torque amplification transform the high-speed rotation of the forward and reverse motor 41 into the low-speed, high-torque rotation of the transmission shaft 38. This satisfies the power requirements of the left and right swaying mechanism for low speed and high torque, ensuring the stability of the vertical sliding sleeve 19's swing and avoiding stress reactions in newborn calves caused by high-speed swaying. The worm gear 36 and worm wheel 37 transmission have self-locking properties, preventing the transmission shaft 38 from rotating in the opposite direction when the equipment stops or when the newborn calves struggle. This prevents the calf riding platform 3 from swinging unexpectedly due to external forces, improving the operational safety of the equipment. The forward and reverse motor 41 simultaneously drives the gear 13 and the worm gear 36, providing synchronous power to the front-back swaying mechanism and the left-right swaying mechanism, achieving motion synchronization between the two swaying mechanisms. This ensures the complex swaying pattern and coordination of the calf riding platform 3, which is closer to the natural activity state of the calf.

[0028] Furthermore, each of the two vertical sliding sleeves 19 has a limiting shaft 32 fixed on one side of its opposite side. Two arc-shaped limiting shaft brackets 33 are symmetrically installed on the surface of the base 1. The surface of the arc-shaped limiting shaft brackets 33 has an arc-shaped groove 34. The limiting shaft 32 is slidably connected in the arc-shaped groove 34. The curvature of the arc-shaped groove 34 is perfectly matched with the swing trajectory of the vertical sliding sleeves 19, providing precise guidance for the sliding of the limiting shaft 32, strictly limiting the swing angle of the vertical sliding sleeves 19, avoiding excessive swing of the vertical sliding sleeves 19, which would cause the calf riding platform 3 to sway too much from side to side, and preventing the newborn calf from having a strong stress response due to excessive swaying. The swing angles of the two vertical sliding sleeves 19 are consistent, achieving bilateral synchronicity of the left and right swaying of the calf riding platform 3, avoiding tilting of the calf riding platform 3 due to excessive swing angle on one side, and improving the stability of the swaying.

[0029] Furthermore, the illumination end of the multi-degree-of-freedom lighting lamp 7 is integrally formed with a trumpet-shaped reflector 9. Multiple shadow-reducing lamps 10 are installed in a ring on the inner surface of the reflector 9. The trumpet-shaped reflector 9 has a light-focusing effect, which can concentrate the light from the multi-degree-of-freedom lighting lamp 7 onto the blood collection site, improve the light intensity of the blood collection site, and solve the problem of blurred vision caused by light dispersion. The reflective effect of the reflector 9 can make full use of the light source, improve the light utilization rate, and reduce lighting energy consumption. The integrally formed structure ensures the structural rigidity of the reflector 9, avoids deformation due to collision and vibration, and ensures the stability of the light-focusing effect. The multiple shadow-reducing lamps 10 installed in a ring allow the light to illuminate the blood collection site from multiple angles, eliminate the shadows caused by a single light source at the blood collection site, achieve shadow-free lighting, and allow the operator to clearly see the direction and location of the blood vessels, greatly improving the speed and accuracy of finding blood vessels, thereby improving blood collection efficiency.

[0030] Working principle and usage process of this invention: The base 1 serves as the supporting foundation for the equipment and is made of stainless steel to ensure overall strength and stability. The inclined platform 2 is installed at an angle on one side of the base 1, and its surface is provided with anti-slip protrusions to facilitate newborn calves to smoothly step onto the calf riding platform 3 and reduce stress response during the guidance process. The calf riding platform 3 is set above the base 1. Its surface is provided with concave pads that fit the contours of the calf's abdomen and neck, so that the calf's body fits naturally and improves comfort. Flexible straps 4 are symmetrically arranged on both sides of the calf riding platform 3. The flexible straps 4 are made of elastic and wear-resistant rubber material and have a buckle adjustment structure at the end, which can flexibly adjust the tightness according to the body shape of the newborn calf, so as to achieve stable fixation while avoiding excessive restraint. The heating pad 5 is detachably installed on the calf riding platform 3 and is placed around the neck of the corresponding newborn calf. Its surface has a needle groove 40 for accurately locating the insertion point of the blood collection tool. The heating pad 5 is electrically connected to the PLC controller and has an operating temperature adjustment range of 38-40℃. It can locally heat the blood collection site to promote blood vessel dilation and further promote blood flow. The support rod 6 is fixedly installed on the surface of the calf riding platform 3. A multi-degree-of-freedom lighting lamp 7 is detachably installed at its top. The illumination end of the multi-degree-of-freedom lighting lamp 7 is integrally formed with a horn-shaped reflector 9. Multiple shadow reduction lamps 10 are installed in a ring on the inner surface of the reflector 9, which can eliminate the shadow in the blood collection area and provide the operator with a clear field of vision. After the parameters are set, a start signal is sent to the PLC controller. After receiving the start signal, the PLC controller controls the forward and reverse motor 41 to start. The output shaft of the forward and reverse motor 41 simultaneously drives the gear 13 and the worm 36 to rotate. The gear 13 meshes with the toothed plate 14, converting the rotational motion of the motor into the horizontal linear motion of the toothed plate 14 in the support groove plate 11. The motion trajectory of the toothed plate 14 is guided and limited by the limit slider 26 and the guide groove 27. When the toothed plate 14 moves horizontally, its end pushes the slider 15 to slide along the limiting slide rod 17 in the support bar groove plate 11. The spring 18 sleeved on the limiting slide rod 17 is compressed, providing elastic potential energy for the slider 15 to reset. The clearance groove 28 opened on the toothed plate 14 can prevent it from interfering with the limiting slide rod 17. The sliding of slider 15 is transmitted to vertical slide bar 21 through hinge rod 16. Vertical slide bar 21 is located inside vertical sliding sleeve 19 and is vertically guided by the cooperation of vertical guide bar 20 and vertical slide groove 22 to achieve reciprocating lifting up and down; Two vertical sliding rods 21 alternately lift up, and the sliding column 23 at the top slides in the strip groove 25 of the fixed sliding seat 24, thereby driving the calf riding platform 3 to make small reciprocating regular swaying in the back and forth direction, simulating the natural activity state of the calf and promoting blood flow to the blood collection site. Slightly swaying back and forth in the left and right direction: The worm gear 36 meshes with the worm wheel 37 fixed on the transmission shaft 38, transmitting power to the transmission shaft 38 and achieving a stable output of high torque and low speed. The gears 31 at both ends of the transmission shaft 38 mesh with the gear rings 30 fixed on the vertical sliding sleeves 19, driving the two vertical sliding sleeves 19 to move synchronously. The vertical sliding sleeves 19 are hinged to the inner wall of the base 1 through the rotating shaft 29 at the bottom. Driven by the gears 31 and the gear rings 30, the two vertical sliding sleeves 19 swing back and forth synchronously around the rotating shaft 29. The limiting shaft 32 on the vertical sliding sleeve 19 slides in the arc groove 34 of the arc-shaped limiting shaft frame 33, strictly limiting the angle range of the left and right swing, avoiding excessive shaking that could cause discomfort to the newborn calf, and ensuring that the entire shaking process is stable and safe. While the calf is rocking back and forth and left and right on the platform 3, the operator uses the clear vision of the multi-degree-of-freedom lighting 7 to accurately position and insert the blood collection needle through the needle groove 40 on the heating pad 5 to collect blood. The pressure sensor built into the equipment monitors the strength of the newborn calf's struggle in real time. When the detected struggle strength exceeds the preset threshold, the PLC controller will automatically control the forward and reverse motor 41 to reduce the speed or stop running. After the newborn calf recovers and stabilizes, it will resume the preset working state, minimizing its stress response and ensuring blood collection safety and the health of the calf. After blood collection is completed, the operator sends a stop command through the control system, and the forward and reverse motor 41 stops running. Under the reset action of the spring 18, components such as the slider 15, hinge rod 16, and vertical slide rod 21 return to their initial positions, and the calf riding platform 3 stops shaking. Then, the operator unties the flexible straps 4 and guides the newborn calf away from the calf riding platform 3, completing the entire blood collection process.
