Description

Technical Field

[0001] This invention relates to the field of sheep assessment technology, specifically to an assessment device for the physiological state of semi-free-range breeding in sheep. Background Technology

[0002] In sheep reproductive management, accurately grasping the reproductive physiological status of individuals is of great significance for improving reproductive efficiency and optimizing herd structure. Currently, fecal testing technology has been widely used in the reproductive monitoring of ruminants. By analyzing hormone metabolites in feces, key physiological information such as the estrous cycle, pregnancy status, and ovarian function of ewes can be obtained. At the same time, the detection of parasite eggs and pathogenic microorganisms in fecal samples can assess the individual's health level and avoid reproductive performance decline due to infection. In addition, changes in stress-related indicators such as cortisol in feces can also reflect the impact of external environmental stress on reproductive physiological status.

[0003] Currently, sheep manure sampling is mainly concentrated in stall-feeding environments, usually by manually collecting fresh manure in the sheepfold. However, with the popularization of semi-free-range and fully free-range feeding models, the activity range of sheep has increased. In open spaces, manure is not easy to locate, and the collection efficiency is low. Moreover, the mixing of the flock makes it difficult to obtain individual manure samples, which seriously affects the accuracy of reproductive physiological status assessment. In addition, manual collection is not only time-consuming and labor-intensive, but also prone to sample contamination, making it difficult to meet the needs of continuous monitoring and undisturbed sampling.

[0004] A Chinese patent discloses a device for collecting ram feces and urine, application number: CN201720598851.X. This device can be used under both stall feeding and grazing conditions, and it is fixed firmly to the experimental sheep. Therefore, there is an urgent need for a technical device suitable for semi-free-range feeding conditions that can automatically or semi-automatically collect feces from individuals, in order to improve the accuracy and efficiency of sample collection and provide reliable support for real-time monitoring and data-driven management of the reproductive physiological status of ewes.

[0016] Compared with the prior art, the advantages of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use; 1. Equipped with a synchronous collection mechanism, the sheep manure receiving structure and dry-wet separation structure are formed by the cooperation of a guide tube, sliding tube, buttock pad, sieve box, drain valve, filter plate, sliding rod, and spring. This promotes dry-wet separation, effectively and promptly removing mucus and urine mixed in the sheep manure. While preventing liquid from mixing with the manure and affecting the collection quality, it also improves the dryness of the manure. This not only improves the smoothness of the manure's movement within the suction tube, making the collection process more efficient and stable, but also prevents the rapid growth of bacteria caused by damp manure. While reducing the bacterial growth rate, it also slows down the fermentation and deterioration of sheep manure. On the other hand, it can be equipped with a diversion guide, manure bottle, partition and mesh for diversion and storage, so as to realize the relatively independent sealing and preservation of sheep manure of each sheep at different times. This can provide a more comprehensive and three-dimensional sheep manure test sample for the assessment and detection of the reproductive physiological status of each sheep during the free-range process. At the same time, it can avoid the collected sheep manure from contacting the ground, which can effectively ensure the freshness and purity of the collected sheep manure sample, effectively avoid interference from miscellaneous bacteria and impurities, and make the detection work more reliable. By combining a slide, pull rod, piston, pull ring, guide valve, and negative pressure pipe, a synchronous conversion structure can be formed. This structure can convert and utilize the energy consumed by sheep during walking, running, and jumping while grazing. Combined with the transmission and limiting effects of ropes, leg rings, hanging ears, and limiting heads, it can appropriately increase the way sheep expend energy during movement, providing stable negative pressure traction during manure collection. This allows for more efficient transfer of manure within the suction pipe, ensuring more stable and precise placement of manure into the manure bottle, thus improving the efficiency of manure collection. Furthermore, appropriately increasing the energy expenditure during sheep movement can assist in exercise, strengthening their physique, promoting better digestion, and facilitating better growth and development.

[0017] 2. An intermittent guiding mechanism is provided. Through the cooperation of the external pipe, guide box, slider, bend, and filter head, a negative pressure guiding structure can be formed. This structure can limit and guide the negative pressure traction force during sheep manure collection, achieving dynamic control of the negative pressure value. This can significantly improve the stability of the negative pressure traction force during sheep manure collection. In addition, the flow-limiting guiding effect of the blower pipe, air inlet pipe, limiting box, plug, and limiting ring can dynamically limit the air pressure value that can be stored in the air storage box. This not only converts and utilizes excess airflow, promoting more stable transfer of sheep manure, but also further improves the dryness of sheep manure. Moreover, it can be adaptively adjusted according to the extra energy consumed by each sheep during free-range activities, meeting the adaptability of sheep manure collection work to sheep of different sizes and growth stages. This makes the collection work more stable and efficient for collecting manure from various sheep during free-range activities, effectively improving the adaptability of sheep manure collection work to sheep flocks and increasing the effective scope of use of the device. By combining an air storage box and a positive pressure pipe, a directional energy storage and conversion structure can be formed. This structure can temporarily store some of the energy consumed by sheep during movement, providing a stable driving force for the conversion of sheep manure collection and discharge. Furthermore, the dynamic linkage of the sliding box, collecting pipe, sliding plate, push rod, sealing plate, leakage hole, and push-pull plate, along with the flow-limiting and shut-off functions of the manure discharge port, on / off valve, light ring, switch, drain valve, and pressure regulating valve, allows for intermittent collection of sheep manure according to actual needs. While ensuring the amount of sheep manure collected per batch, excess manure can be discharged promptly to prevent clogging. This makes the manure collection process more stable and avoids manure accumulation that increases the burden on the device and sheep. In addition, the synchronous collection mechanism guides the manure and provides relatively independent sealing and storage, enabling more precise quantitative collection of manure at different times during sheep grazing. This more efficiently meets the needs of assessing and detecting the reproductive physiological state of sheep.

[0018] In summary, this device can simultaneously collect sheep manure at different times during the grazing process according to actual needs, and can also achieve intermittent quantitative packaging and storage of sheep manure at different times. At the same time, it can promote the separation of dry and wet manure, effectively improve the quality of sheep manure collection, and make the collected sheep manure samples purer. In addition, by consuming some of the sheep's physical energy during exercise, it provides directional negative pressure adsorption force for the sheep manure collection work. While making the sheep manure collection work smoother and more stable, it can also play an auxiliary exercise role, improving the growth and health of the sheep.

[0019] Furthermore, this device, combined with the characteristics of semi-free-range feeding, significantly improves the feasibility and accuracy of monitoring reproductive physiological status under semi-free-range conditions through real-time, targeted, and pollution-free collection of sheep manure. Compared to traditional methods that can only collect manure samples in sheep pens, this device can obtain manure samples under the natural behavior of sheep moving freely, avoiding hormone level deviations caused by human interference or environmental changes. This ensures that the test data is closer to the sheep's true physiological state, improving the scientific rigor of reproductive pattern analysis. At the same time, the continuous, automated, and multi-time-segment sample collection achieved by the device can form a single, multi-dimensional, and high-temporal-resolution manure sample database, providing richer and more accurate evidence for subsequent estrus monitoring, pregnancy diagnosis, stress assessment, nutritional level judgment, and potential pathogen screening in ewes.

[0020] The device can operate stably for a long time in a semi-free-range environment, has a strong structural adaptability, and can complete sampling without changing the sheep's normal activity patterns. This further enhances its applicability and promotional value in actual breeding scenarios. Overall, this device not only solves the technical pain points of difficult sheep manure collection, high sample contamination rate, and difficulty in distinguishing individual samples under free-range conditions, but also provides an efficient, reliable, and innovative technical approach for monitoring the reproductive performance and health management of semi-free-range sheep flocks, which has significant practical significance and economic benefits.

[0026] The working principle and usage process of this invention: In actual use, the fecal collection and preservation device for assessing the physiological state of semi-free-range sheep breeding firstly selects a restraint belt 1 of appropriate size according to the sheep's physique and puts it on the sheep's body, so that the sheep's legs pass through the four leg binding rings 217. Pull the restraint belt 1, and after it is in close contact with the sheep's body, drag the male buckle 16 and female buckle 17 to make a slight adjustment to the overall restraint position of the restraint belt 1, so that the rump pad 203 is aligned with the sheep's buttocks, and pull the restraint belt 1 closer so that the rump pad 203 is in close contact with the sheep's buttocks. Then, fix the restraint belt 1 in the current position on the sheep's body through the male buckle 16 and female buckle 17, and tighten the leg binding rings 217 to provide auxiliary fixation for the restraint belt 1. Then, air is injected into the slide cylinder 210 through the regulating valve 13 to limit the air pressure in the space outside the pull rod 211 inside the slide cylinder 210, and adjust the air pressure on the end face of the piston 212. This air pressure is the reset pushing air pressure of the piston 212 during the working process. Air is also injected into the limiting box 322 through the air nozzle 15 to limit the air pressure on the end face of the block 323. This air pressure is the maximum air pressure that the air storage box 306 can store during the working process, and the block 323 slides towards the blower pipe 320 side under the action of this air pressure, so as to block the air filling pipe 321. Next, air is injected into the sliding box 309 through the pressure regulating valve 319 to adjust the air pressure in the space outside the push rod 312 inside the sliding box 309, limiting the air pressure on the end face of the sliding plate 311. This air pressure is the adjustment air pressure of the sealing plate 313 during operation. Under the action of this air pressure, the sliding plate 311 drags the push-pull plate 315 close to the guide seat 208 through the push rod 312, so that the sealing plate 313 is completely embedded in the guide seat 208. At this time, the manure outlet 300 is blocked by the sealing plate 313, while the leakage hole 314 is aligned and connected with the bottle mouth of the manure bottle 209. Next, the air inside the guide box 302 is extracted through the negative pressure valve 14, so that the space inside the guide box 302 between the negative pressure valve 14 and the slider 303 is in a negative pressure state. Adjust the negative pressure, and the negative pressure value is equal to the negative pressure value of sheep manure adsorption during the working process, so that the slider 303 is moved to the side of the negative pressure valve 14 under the traction of the negative pressure, so that it blocks the communication port of the filter head 305. It should be noted that during the aforementioned adjustment process, the air pressure on the end face of piston 212 should be greater than the maximum air pressure that can be stored inside air storage box 306, and the maximum air pressure that can be stored inside air storage box 306 should be greater than the air pressure on the end face of slide plate 311. At the same time, the absolute value of the negative pressure between negative pressure valve 14 and slider 303 should be less than the maximum air pressure that can be stored inside air storage box 306. The aforementioned process of adjusting the initial air pressure at various locations can also be uniformly adjusted before the restraint strap 1 is put on the sheep. The specific order can be flexibly adjusted according to individual work habits. During the adjustment process, the air pressure on the corresponding restraint strap 1 can be adjusted proportionally according to the size and growth status of each sheep. After the aforementioned adjustment work is completed, and after the clean manure bottle 209 is installed on the guide seat 208, and after the power supply circuit of the storage battery 12, the light ring 316 and the switch 317 is connected, the sheep manure collection and preservation work can be officially carried out. During the collection of sheep manure, after the aforementioned adjustments, in the initial state, the mouth of the manure bottle 209 is aligned with the leakage hole 314. At this time, the manure bottle 209 and the guide seat 208 remain unobstructed. As the sheep moves during the grazing process, the leg binding ring 217 will move back and forth synchronously with its limbs. Then, under the limitation of the hanging ear 218 and the limiting head 219, the rope 216 will intermittently pull the pull rod 211 through the pull ring 213. When the pull rod 211 is pulled, it will overcome the air pressure on the end face of the piston 212 on one side of the pull rod 211, and drive the piston 212 to slide towards the pull ring 213 inside the slide cylinder 210. When the pull rod 211 is not pulled, the piston 212 will return to its original position under the pressure of the air pressure on the end face of the pull rod 211. As the sheep walks, the piston 212 will move back to its original position inside the slide cylinder 210. Furthermore, under the guiding action of the flow guide valve 214, during the reciprocating motion of the piston 212, the airflow inside the guide seat 208 will be continuously drawn through the negative pressure pipe 215, so that the top of the bottle mouth of the fecal bottle 209 is in a negative pressure state. At the same time, under the conduction of the fecal suction pipe 207, the airflow inside the sieve box 204 will also be synchronously pulled and present a negative pressure state. With the connection of the guide cylinder 201 and the slide pipe 202, the concave part of the end face of the buttock pad 203 will also present a negative pressure state. As the piston 212 continues to move and continuously draws airflow, the negative pressure inside the guide tube 201 will further increase. With the connection of the outer pipe 301, the slider 303 inside the guide box 302 will also be simultaneously pulled by the negative pressure. When it is sufficient to overcome the pull of the negative pressure on the other end of the slider 303, the slider 303 will move to the side of the outer pipe 301, so that the filter head 305 is connected to the outer pipe 301 through the bend 304. At this time, the external airflow will be pulled by the negative pressure. After being filtered by the filter head 305, it enters the guide tube 201 through the bend 304 and the outer pipe 301 to compensate for the airflow, so that the negative pressure inside the guide tube 201 and the negative pressure between the slider 303 and the guide valve 214 are kept in a balanced state. Furthermore, the negative pressure above the bottle mouth of the fecal bottle 209 will be kept in a dynamic balance state. Furthermore, under negative pressure traction, when sheep defecate, under the dual traction of gravity and negative pressure, the sheep feces will fall into the concave part of the buttock pad 203, and fall into the sieve box 204 along the slide tube 202 and guide tube 201. Under the sieving and filtering of the filter plate 206, if the sheep feces contain liquid, the liquid will pass through the filter plate 206 and be discharged through the drain valve 205, while the sheep feces will roll along the filter plate 206 under the dual action of gravity and negative pressure, and fall into the suction pipe 207. Further, under the action of negative pressure and gravity, it will enter the guide seat 208 along the suction pipe 207. Subsequently, under the dual traction of negative pressure and gravity, sheep manure will pass through the first drain hole 314 on one side of the suction pipe 207 and fall into the opposite manure bottle 209. As more sheep manure falls into the manure bottle 209, when the manure bottle 209 is full, the sheep manure will block the light emitted by the lamp ring 316. After the light is lost, the switch 317 will give a control signal to the on / off valve 308, causing the on / off valve 308 to open briefly and then close. During the reciprocating motion of the piston 212, the airflow drawn in through the negative pressure pipe 215 is forced into the air storage box 306 through the positive pressure pipe 307, where it is stored and accumulated, causing the air pressure inside the air storage box 306 to rise. After the on / off valve 308 is opened, the stored airflow enters the manifold 310 through the on / off valve 308 and then enters the slide box 309. As can be seen from the aforementioned adjustment, the maximum air pressure stored inside the air storage box 306 is greater than the air pressure on the end face of the slide plate 311 on one side of the push rod 312. As a result, the airflow entering the slide box 309 through the manifold 310 will push the slide plate 311 to move accordingly. Driven by the sliding plate 311, the push rod 312 will cause the push-pull plate 315 to slide, causing the sealing plate 313 to slide towards the suction pipe 207. Finally, when the sliding plate 311 abuts against the limiting ring 324, the sealing plate 313 will block the opening above the bottle mouth of each manure bottle 209, and the manure discharge port 300 will also be connected to the leakage hole 314 at the same time, and will remain in this state for a period of time. The excess sheep manure will be discharged through the leakage hole 314 and the manure discharge port 300. After the aforementioned on / off valve 308 is closed, in the subsequent process, as the sheep moves, the airflow pushed by the piston 212 will accumulate again inside the air storage box 306. As the air pressure inside the air storage box 306 rises, with the connection of the blower pipe 320, the airflow inside the air storage box 306 will enter the restrictor box 322. When it is sufficient to overcome the air pressure on the other end of the block 323, the block 323 will be pushed to the side of the air nozzle 15, no longer blocking the inflation pipe 321, and the airflow will then enter the guide tube 201 through the inflation pipe 321. This allows for the release and depressurization of the airflow inside the air storage box 306, maintaining a balance between the air pressure inside the air storage box 306 and the air pressure between the air nozzle 15 and the block 323. Even if the air pressure inside the air storage box 306 remains at the maximum storable air pressure value set during the adjustment process, the excess airflow entering the guide tube 201 through the air filling pipe 321 will simultaneously fill the screen box 204, the manure suction pipe 207, and the guide seat 208, intermittently impacting and pushing the sheep manure, thus facilitating the smoother transfer and discharge of the sheep manure. After a period of time, the drain valve 318 is opened manually by the external controller. The airflow that was injected into the slide box 309 through the collection pipe 310 will be discharged through the drain valve 318. After losing the airflow support, the slide plate 311 will be pushed by the air pressure on the side of the push rod 312 and the push-pull plate 315 will be pushed back to its original position by the push rod 312. The sealing plate 313 will also be reset, so that the manure outlet 300 is blocked by the sealing plate 313 again, and the leakage hole 314 is aligned with the bottle mouth of the manure bottle 209 for connection. Subsequently, when the sheep defecate, under the traction of gravity and negative pressure, the sheep manure enters the guide seat 208. Since the first manure bottle 209 on one side of the suction pipe 207 is already full of sheep manure, it will pass through the second drain hole 314 on that side under the traction of negative pressure and fall into the corresponding second manure bottle 209 on that side. Then the aforementioned process will be repeated. In the process of operation, the drain valve 318 is opened intermittently at regular intervals, so that sheep manure at different times during the free-range process can be collected and preserved through different manure bottles 209, providing a stable sample for the assessment and detection of the reproductive physiological status of each sheep during the free-range process.
