Description

Technical Field

[0001] This invention relates to the field of animal husbandry technology, specifically to a positioning device for sheep mating with a limiting function. Background Technology

[0002] In livestock farming, sheep breeding is a crucial step in ensuring flock reproduction and improving farming efficiency. Scientific and rational breeding practices can not only increase conception rates but also optimize sheep genes, improving the growth performance and disease resistance of offspring. Sheep need to be positioned during breeding, but existing sheep breeding positioning devices still have certain shortcomings, such as: The "Special Frame for Sheep Breeding" with application number CN201520681114.7 lacks the function of limiting the sheep's hind limbs and can only position the sheep's head. This leads to problems such as swaying and displacement of the sheep during the breeding process due to the lack of limb restraint. This not only interferes with the smooth progress of the breeding operation and increases the difficulty of manual intervention, but also directly reduces the breeding efficiency and success rate. Furthermore, it cannot automatically spray cleaning liquid to disinfect and clean the breeding area of ​​the sheep before breeding, which can easily breed bacteria and spread diseases. This not only affects the health of the sheep, but also further restricts the standardization and hygiene and safety level of breeding operations. In view of this, and in response to the above problems, we conducted in-depth research and proposed a positioning device for sheep mating with a positioning function. Summary of the Invention

[0003] The purpose of this invention is to provide a sheep mating positioning device with a limiting function, so as to solve the problems mentioned in the background art of poor limiting effect and inability to automatically clean and disinfect existing positioning devices.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a positioning device for sheep mating with a limiting function, comprising a base plate and a ramp fixedly installed at its rear end; A bracket is fixedly installed at the front end of the top of the base plate, and a fixing tube is fixedly installed on the inner wall of the bracket. An electric telescopic rod is fixedly installed on the top surface of the bracket, and the output shaft of the electric telescopic rod movably passes through the top of the bracket and is fixedly connected to the moving tube. The base plate has clamps on its upper left and right sides at the rear, and the clamps are installed at the rear end of the moving mechanism. The moving mechanism is mounted on the base plate and is connected to an adjustment mechanism mounted on the base plate. A liquid storage tank is mounted on the front bottom of the base plate and is connected to the nozzle through a liquid delivery mechanism. The liquid delivery mechanism is connected to the moving mechanism through a transmission mechanism and is mounted on the bottom surface of the base plate through a fixed plate. The nozzle is movably connected to a rotating mechanism mounted on the base plate and is connected to a drive mechanism mounted on the fixed plate. An auxiliary heating mechanism is mounted on the liquid delivery mechanism and is connected to a fragrance mechanism mounted on the top surface of the base plate.

[0005] The above technical solution facilitates the restriction of sheep's head and hind limbs, automatic cleaning and disinfection of the mating area, temperature control of the cleaning solution, and creation of environmental fragrance. It comprehensively solves the problems of poor restriction effect and insufficient hygiene protection of traditional devices, and improves the stability, safety and standardization of mating operations.

[0006] As a preferred embodiment of the present invention, the moving mechanism includes a first motor fixedly installed on the bottom surface of the base plate, and a first bidirectional lead screw is keyed to the shaft end of the first motor. Two slide blocks are symmetrically sleeved on the outer side of the first bidirectional lead screw, and the first bidirectional lead screw is threadedly connected to the slide blocks. The top surface of the slide blocks is slidably connected to the bottom surface of the base plate, and a moving frame is fixedly installed on the bottom surface of the slide blocks. The moving frame passes through a first through slot opened in the base plate, and a mounting rod is slidably provided on the moving frame. The rear end of the mounting rod is connected to the clamp through a bearing.

[0007] By adopting the above technical solution, it is convenient to drive the first bidirectional lead screw to rotate through the first motor, thereby driving the two slides and the moving frame to slide relative to or opposite to each other, and thus adjusting the lateral distance of the clamps on both sides, providing a basic adjustment function for the hind limb limit, and ensuring the adaptability and stability of the limit.

[0008] As a preferred embodiment of the present invention, the adjustment mechanism includes a second motor fixedly installed on the bottom surface of the base plate. The shaft end of the second motor is keyed to a first screw, and the rear end of the first screw is connected to a fixing block fixedly installed on the bottom surface of the base plate via a bearing. A connecting plate is sleeved on the outer side of the first screw, and the connecting plate passes through a second through slot opened on the base plate. The connecting plate is slidably connected to the second through slot. A straight plate is fixedly installed on the top surface of the connecting plate, and the top surface of the straight plate is slidably connected to a slider fixedly installed at the front end of the bottom of the mounting rod.

[0009] By adopting the above technical solution, it is convenient to drive the first screw to rotate through the second motor, thereby moving the connecting plate and the straight plate back and forth. With the help of the slider, the mounting rod is pushed to slide laterally along the moving frame, so as to realize the adjustment of the front and rear position of the clamp, so that the clamp can effectively fit the limiting part of the sheep's hind limb.

[0010] As a preferred embodiment of the present invention, the infusion mechanism includes a cylinder fixedly installed on the left side of the bottom of the base plate, and a suction pipe is fixedly connected to the bottom front end of the cylinder, and the suction pipe is fixedly connected through the bottom of the storage tank. The front end of the left side wall of the cylinder is fixedly connected to one end of a hose, and the other end of the hose is fixedly connected to a nozzle. A sliding rod is slidably provided through the rear side wall of the cylinder, and a piston adapted to the cylinder is fixedly installed at the front end of the sliding rod, and the sliding rod slidably passes through the fixing plate.

[0011] By adopting the above technical solution, it is easy to drive the piston to slide back and forth in the cylinder through the slide rod, and to draw the cleaning and disinfection liquid from the storage tank through the liquid extraction pipe, and then deliver it to the nozzle through the hose, so as to achieve stable delivery and spraying of the cleaning liquid.

[0012] As a preferred embodiment of the present invention, the transmission mechanism includes a housing fixedly installed on the left side of the bottom surface of the base plate, and a first bidirectional lead screw passes through the right side wall of the housing through a bearing. The left end of the first bidirectional lead screw is connected to the rear end of the second screw through a bevel gear set. The second screw passes through the front side wall of the housing through a bearing, and the front end of the second screw is connected to the rear side of the fixed plate through a bearing. A connecting plate is sleeved on the outer side of the second screw, and the second screw is threadedly connected to the connecting plate. The top surface of the connecting plate is slidably connected to the bottom surface of the base plate, and the front side of the connecting plate is fixedly connected to the rear end of the slide rod.

[0013] By adopting the above technical solution, it is convenient to drive the bevel gear set and the second screw to rotate through the rotation of the first bidirectional lead screw, thereby driving the connecting plate to move the slide bar back and forth, and realizing the reciprocating motion of the piston.

[0014] As a preferred embodiment of the present invention, the rotating mechanism includes a rotating rod that passes through the base plate via a bearing, and a movable plate is fixedly installed at the top of the rotating rod. A retaining seat is fixedly installed at the top surface of the movable plate away from the rotating rod, and the retaining seat is movably engaged with the nozzle.

[0015] The above technical solution facilitates the rotation of the movable plate and the card holder by rotating the rotating rod, thereby adjusting the angle of the nozzle and enabling the nozzle to be aimed at the sheep breeding area, thus improving the targeting of cleaning and disinfection. At the same time, the movable snap-fit ​​design of the card holder and the nozzle allows for quick disassembly of the nozzle for maintenance, replacement, or individual use, enhancing the flexibility and practicality of the device.

[0016] As a preferred embodiment of the present invention, the driving mechanism includes a driving rod that slides through a fixed plate. The front end face of the driving rod movably abuts against the bottom surface of a push rod, and the front end face of the driving rod and the bottom surface of the push rod are inclined surfaces that match each other. The push rod slides through the base plate and the fixed tube in sequence, and the push rod is located below the moving tube. A rack is fixedly installed at the rear end of the push rod, and the rack meshes with a driving gear fixedly installed at the lower end of the rotating rod surface. A circular plate is fixedly installed on the surface of the driving rod, and the front side of the circular plate is fixedly connected to the rear end of a tension spring. The tension spring is sleeved on the outside of the driving rod, and the front end of the tension spring is fixedly connected to the rear side of the fixed plate.

[0017] The above technical solution facilitates the use of the lifting and lowering motion of the moving tube to trigger the nozzle angle adjustment. When the moving tube is pressed down, it pushes the push rod downward, which, through the inclined plane, drives the drive rod to move backward and stretches the tension spring. The rack moves synchronously, driving the drive gear and rotating rod to rotate, thus turning the nozzle to the seeding area. After seeding, the moving tube moves upward, the tension spring resets, and drives the drive rod, push rod, and rack back to their original positions, automatically resetting the nozzle. No manual operation is required, improving the linkage and automation level of the device's actions.

[0018] As a preferred embodiment of the present invention, the auxiliary heating mechanism includes an air inlet pipe fixedly disposed through the rear end of the left side wall of the cylinder, an air outlet pipe fixedly disposed through the rear end of the bottom of the cylinder, and the air outlet pipe fixedly penetrates the rear and front side walls of the liquid storage tank. A box body is fixedly installed on the inner bottom surface of the liquid storage tank, and a liquid extraction pipe is fixedly disposed through the bottom of the box body. The air outlet pipe is fixedly disposed through the rear and front side walls of the box body, and a through hole is opened at the lower end of the right side wall of the box body. The air outlet pipe has a serpentine shape in the box body. An electric heating plate is fixedly installed inside the rear side of the cylinder body.

[0019] The above technical solution facilitates the heating of the gas at the rear of the cylinder by an electric heating plate. When the hot gas is transported through the serpentine gas outlet pipe, it preheats the box and the cleaning liquid inside through heat conduction, avoiding the stress response caused by the low-temperature cleaning liquid to the sheep. The serpentine structure design extends the heat exchange path, improves heating efficiency and uniformity, and the through holes ensure that the cleaning liquid in the storage tank can be continuously replenished to the box, ensuring the continuity of preheating and liquid supply.

[0020] As a preferred technical solution of the present invention, the fragrance mechanism includes a box body fixedly installed on the front end of the top of the base plate, the top surface of the box body is provided with an openable lid, the air outlet pipe is fixedly installed through the bottom of the base plate and the bottom of the box body, and a bracket is fixedly installed on the inner wall of the box body. The left and right side walls of the box body are fixedly provided with air supply pipes, and the top of the air supply pipes are evenly provided with multiple air outlet holes.

[0021] The above technical solution facilitates the use of gas discharged through the gas supply pipe to carry the fragrance medium on the rack, and evenly diffuse it into the mating environment through the gas outlet of the gas supply pipe, thereby improving the odor of the mating area. At the same time, a fragrance that the sheep like can be selected to alleviate their stress response and improve the comfort and cooperation of the sheep during mating. The box lid can be opened to facilitate the replacement of the fragrance medium and adapt to different usage needs.

[0022] As a preferred embodiment of the present invention, a third motor is fixedly installed on the right side of the bracket, and the output shaft of the third motor passes through the right side wall of the bracket via a bearing. A second bidirectional lead screw is keyed to the shaft end of the third motor, and the left end of the second bidirectional lead screw is connected to the left side of the vertical plate fixedly installed on the top surface of the base plate via a bearing. A guide rod is provided on the front side of the second bidirectional lead screw, and the right end of the guide rod is fixedly connected to the inner right side wall of the bracket, and the left end of the guide rod is fixedly connected to the left side of the vertical plate. Two limiting frames are symmetrically sleeved on the outer side of the second bidirectional lead screw, and the second bidirectional lead screw is threadedly connected to the limiting frames, and the guide rod slides through the limiting frames.

[0023] By adopting the above technical solution, it is convenient to drive the second bidirectional lead screw to rotate through the third motor, thereby causing the two limiting frames to slide towards or away from each other along the guide rod, clamping and limiting the sheep's body on both sides. Combined with the limiting structure of the head and hind limbs, it forms a comprehensive limiting and fixing, effectively preventing the sheep from shaking or shifting during mating, and further improving the stability and safety of mating operations.

[0024] Compared with the prior art, the beneficial effects of the present invention are: the sheep mating positioning device with limiting function; 1. The sheep's head is clamped by a moving tube driven by an electric telescopic rod, which works in conjunction with a fixed tube to hold the neck. The hind limbs are fixed in a close fit by adjusting the lateral spacing of the clamps with the moving mechanism and adjusting the front and rear positions of the clamps with the adjusting mechanism. Compared with traditional single-part positioning devices, this effectively avoids problems such as sheep shaking and displacement during mating, reduces the difficulty of manual intervention, significantly improves the stability and success rate of mating operations, and provides a reliable guarantee for precision mating. 2. Relying on the linkage design of the mobile mechanism and the transmission mechanism, the infusion mechanism can be driven without an additional power source, realizing the automatic extraction, delivery and spraying of cleaning and disinfection liquid. At the same time, through the cooperation of the drive mechanism and the rotation mechanism, the nozzle is adjusted to turn towards the mating area during the head positioning process, ensuring that the cleaning liquid is sprayed to the target area. This completely solves the problems of manual cleaning and incomplete disinfection in traditional devices, realizes the automation of the cleaning and disinfection process, effectively reduces the risk of bacterial growth and disease transmission in the mating area, protects the health of sheep, and promotes the standardization and hygiene of mating operations. 3. The added auxiliary heating mechanism heats the gas through an electric heating plate. When the hot gas is transported through the serpentine gas outlet pipe, it fully exchanges heat with the cleaning liquid in the storage tank, thus preheating the cleaning liquid. This avoids the stimulation to sheep caused by direct spraying of low-temperature cleaning liquid, and reduces the struggling and resistance behaviors of sheep caused by stress reactions. It not only ensures the smoothness of the mating process, but also further improves the welfare level of sheep. It is especially suitable for mating operations in low-temperature environments. 4. After the auxiliary heating unit completes its preheating function, the gas discharged from it is introduced into the fragrance unit and comes into contact with the fragrance medium. The fragrance is then evenly diffused into the mating environment through the gas delivery pipe. On the one hand, this can improve the smell of the mating area. On the other hand, a fragrance medium that the ewes like can be selected to relieve their tension, or a scent similar to that of rams can be selected to attract ewes in estrus to soothe their emotions and stimulate their estrus response. This improves the comfort and cooperation of the sheep during the mating process, indirectly increasing the success rate of mating and forming an integrated environmental optimization solution of "cleaning-preheating-scenting". 5. The limiting frame is driven by a third motor to clamp the sheep in opposite directions, forming a three-dimensional limiting structure with the head and hind limbs, which further improves the stability of sheep limiting.

Multiple air outlets are evenly opened on the top of the air supply pipes 48.

[0038] Working principle: When in use, after the sheep walks up the ramp 6 onto the base plate 1, the electric telescopic rod 5 is activated. The electric telescopic rod 5 drives the moving tube 4 to slide down along the inner wall of the bracket 2, which, together with the fixed tube 3, clamps and limits the sheep's neck to achieve head positioning. After the moving tube 4 moves downward and contacts the push rod 36, it will push the push rod 36 downward, causing the drive rod 35 to move backward. This will cause the drive rod 35 to drive the rack 37 to move backward synchronously, and cause the circular plate 39 to move synchronously to stretch the tension spring 40. Since the rack 37 meshes with the drive gear 38, the drive gear 38 drives the rotating rod 31 to rotate. The rotating rod 31 drives the card seat 33 to rotate through the movable plate 32. The card seat 33 drives the nozzle 23 to rotate synchronously, so that the nozzle 23 rotates to face the sheep mating area. Then, the first motor 7 is started, which drives the first bidirectional lead screw 8 to rotate. The first bidirectional lead screw 8 drives the two slide blocks 9 to slide towards each other along the bottom surface of the base plate 1. The slide blocks 9 drive the moving frame 10 to move synchronously along the first through groove 49. The moving frame 10 drives the clamps 12 to move towards each other through the mounting rod 11 until the clamps 12 fit against both sides of the sheep's hind legs. At the same time, the second motor 13 is started, which drives the first screw 14 to rotate. The first screw 14 drives the connecting plate 16 to slide back and forth along the second through groove 34. The connecting plate 16 drives the straight plate 17 to move synchronously. The straight plate 17 pushes the mounting rod 11 to slide laterally along the moving frame 10 through the slider 18, adjusting the front and back position of the clamps 12, so that the sheep's hind legs can be limited and fixed by the clamps 12. When the first bidirectional lead screw 8 drives the two slide blocks 9 to move towards each other, it drives the second screw 27 to rotate through the bevel gear set 28. The second screw 27 drives the connecting plate 30 to slide backward along the bottom surface of the base plate 1. The connecting plate 30 pushes the slide rod 24 to move backward along the fixed plate 29. The slide rod 24 drives the piston 25 to slide backward inside the cylinder 19. The hot air heated by the electric heating plate 45 in the right side area inside the cylinder 19 can be transported through the air outlet pipe 42. The air outlet pipe 42 runs through the box 43 in a serpentine shape. The cleaning and disinfection liquid in the box 43 is preheated by heat conduction so as to avoid low temperature liquid irritating the sheep when spraying it to the sheep mating area. When the piston 25 moves backward, the cleaning and disinfection liquid is drawn from the box 43 through the liquid extraction pipe 20 in the front area of ​​the cylinder 19. The gas delivered by the vent pipe 42 is delivered to the box 46. After contacting the fragrance medium on the bracket 47, the gas carrying the fragrance is discharged through the vent of the vent pipe 48, thereby improving the breeding environment. At the same time, by releasing a scent that ewes like, the stress response of the ewes can be relieved, or a scent similar to that of rams can be released to attract ewes in estrus to soothe their emotions and stimulate their estrus response. Subsequently, the first motor 7 drives the first bidirectional lead screw 8 to rotate in the opposite direction, causing the two clamps 12 to move away from each other, thereby opening the sheep's two hind legs for mating. At the same time as the first bidirectional lead screw 8 rotates in the opposite direction, the second screw 27 rotates in the opposite direction through the bevel gear set 28, causing the slide rod 24 and piston 25 to move forward, delivering the cleaning and disinfecting liquid to the nozzle 23 through the hose 22, so that the cleaning and disinfecting liquid is sprayed onto the sheep mating area, realizing automatic disinfection and cleaning of the sheep mating area; at the same time, gas is drawn into the rear area of ​​the cylinder 19 through the air inlet pipe 41 and heated by the electric heating plate 45. After mating, the hind limbs of the sheep are released from fixation, and the moving tube 4 is moved upward by the electric telescopic rod 5. At this time, under the pulling action of the tension spring 40, the electric drive rod 35 of the circular plate 39 moves forward to reset, so that the push rod 36 is reset upward and the rotating rod 31 is reset to rotate and drive the nozzle 23 to reset. The design of the nozzle 23 engaging with the bracket 33 allows the nozzle 23 to be removed for flexible use.

[0039] Example 2

[0040] Specifically, such as Figure 11 - Figure 12As shown, the difference between this embodiment and Embodiment 1 is that a third motor 50 is fixedly installed on the right side of the bracket 2, and the output shaft of the third motor 50 passes through the right side wall of the bracket 2 through a bearing. The shaft end of the third motor 50 is keyed to a second bidirectional lead screw 51, and the left end of the second bidirectional lead screw 51 is connected to the left side of the vertical plate 52 fixedly installed on the top surface of the base plate 1 through a bearing. A guide rod 53 is provided on the front side of the second bidirectional lead screw 51, and the right end of the guide rod 53 is fixedly connected to the right inner wall of the bracket 2, and the left end of the guide rod 53 is fixedly connected to the left side of the vertical plate 52. Two limiting frames 54 are symmetrically sleeved on the outer side of the second bidirectional lead screw 51, and the second bidirectional lead screw 51 is threadedly connected to the limiting frame 54. The guide rod 53 is slidably installed through the limiting frame 54.

[0041] With the above structural design, by starting the third motor 50, the third motor 50 drives the second bidirectional lead screw 51 to rotate, and the second bidirectional lead screw 51 drives the two limit frames 54 to slide towards each other along the guide rod 53, thereby limiting the two sides of the sheep's body and further improving the positioning stability.
