Description

Technical Field

[0001] This utility model relates to the field of pig farming technology, and in particular to an automatic counting device for penned pigs. Background Technology

[0002] In large-scale livestock farming, the management and transportation of pigs are crucial for ensuring farming efficiency and controlling the spread of diseases. This is especially true for the transfer of weaned piglets, culled sows, and fattening pigs. The standardization of these procedures directly impacts farm biosecurity and economic benefits. During the loading of these pigs onto external transport vehicles, they must move from the farm to the transport platform via specific aisles. However, during this process, pigs are susceptible to external environmental stimuli and the methods used by personnel, leading to backtracking or turning back. Since external transport vehicles and personnel coming into contact with pigs inside and outside the farm may carry unknown sources of risk such as pathogens and contaminants, the returning pigs will directly or indirectly bring potential external contaminants into the farm. Breaking the biosecurity isolation system within the farm can easily lead to the spread of diseases, posing a serious threat to overall farm safety. Accurate counting is a fundamental prerequisite for standardized management during pig transport, directly impacting slaughter statistics, cost accounting, and the formulation of subsequent disease prevention measures. Currently, some pig farms in the industry use manual counting, but this method has significant drawbacks: when pigs move back and forth in aisles and become congested, double counting or omissions are likely, making it difficult to guarantee counting accuracy. Furthermore, manual intervention increases the frequency of contact between personnel and pigs, further increasing biosecurity risks, and is inefficient and unsuitable for the transport needs of large-scale farming.

[0003] To address the drawbacks of manual counting, automated counting devices have been developed and applied in related technical fields. For example, Chinese Patent No. CN214586989U discloses a pig counting device for a pig farm aisle. This device uses a trapezoidal base, side plates, a weighing platform, and an infrared sensor. The weighing sensor responds to the pressure of the pigs, and the infrared sensor senses the passing of pigs and outputs pulse signals. Combined with a display screen, the counting results are visualized, which improves the convenience of pig counting to a certain extent.

[0004] However, existing technologies still have significant defects and shortcomings: On the one hand, existing pig farm passageways are mostly simple channel structures, lacking a dedicated design to prevent pigs from flowing back. The baffles and other components they are equipped with cannot effectively restrict pigs from backtracking or flowing back. Once pigs flow back, it will directly cause the counting device to count repeatedly or deviate from the count, seriously affecting the counting accuracy. On the other hand, pigs flowing back and moving disorderly can easily cause congestion and disorder in the passageways, which not only further aggravates the counting error, but may also paralyze the transfer process. Additional manpower is required for guidance and handling, which reduces the transfer efficiency and increases the risk of contact between personnel and pigs, which is not conducive to biosecurity control. Therefore, it is necessary to improve the design. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes an automatic counting device for penned pigs, which can more accurately solve the problems described above.

Both the front and rear sides of the top of the base are fitted with passageway railings by screws, forming a passageway between two of the railings. A locking and limiting mechanism is fixedly installed at the top center of each passageway railing. A shaft is rotatably connected to the inner center of the locking and limiting mechanism. One-way gates are fixedly installed in a ring at equal intervals on the outer surface of the shaft. A counting mechanism is located at the output end of the passageway inside the railings on the top of the base. A controller is fixedly installed on the top of one of the railings. The one-way gates are used to limit the pigs' movement in one direction. When a pig passes through, it squeezes the one-way gate, causing the shaft to rotate. This rotation allows the pig to pass through the passageway. When a pig retreats, the locking and limiting mechanism prevents the shaft on the one-way gate from rotating in the opposite direction, thus preventing the pig from retreating.

[0008] The counting mechanism includes a guide plate, which is installed inside the passage railing near the exit by screws. A side arm is fixedly installed on the outer side of the guide plate, and a mounting side plate is fixedly installed through the passage railing on the side arm. An infrared beam sensor is fixedly installed on the middle of the outer side of the mounting side plate.

[0009] Furthermore, a reserved slot is provided at one end of the passage guardrail near the installation side plate.

[0013] Further, the limit module comprises a ratchet wheel and a turntable, the ratchet wheel is rotatably connected to the middle part of the outer side of the mounting disc, two ends of the shaft body are connected with the inner side of the ratchet wheel through couplings, the turntable is rotatably connected to the upper end of the outer side of the mounting disc, a limit arm is fixedly mounted on the outer side of the turntable, the lower end of the limit arm is fixedly connected with a limit tooth cone, the limit tooth cone is in meshed connection with the ratchet wheel, the limit tooth cone can naturally fall under its own gravity to be in limit meshing with the ratchet wheel to realize the function of unidirectional transmission, and prevent pigs from flowing back and moving backward.

[0014] Further, a weight plate is fixedly mounted on the outer side of the limit arm at one end close to the limit tooth cone, a weight ball is fixedly mounted on the outer side of the weight plate, a covering shell is covered on the outer side of the mounting disc, the covering shell is used for covering the limit module, and can cover and protect the limit structures such as the ratchet wheel, and the weight ball is used for providing power for the limit tooth cone to ensure that it stably sinks and engages with the ratchet wheel to form unidirectional rotation of the shaft body.

[0015] Beneficial effects of the utility model:

[0016] 1. During the application of this technical solution, by arranging the locking limit mechanism and the guiding structure of the channel guardrail, the moving direction of pigs can be unidirectionally limited during use, so as to prevent the pigs from retreating during the transportation process, and at the same time guide the pigs to move orderly along the preset path, avoid the aisle congestion caused by disorderly shuttling of pigs, thereby achieving the effects of reducing manual intervention and lowering the risk of cross-transmission of pollutants inside and outside the farm, solving the problems in the prior art such as biosafety threats caused by pig backflow, easy aisle congestion requiring manual guidance, and frequent contact between personnel and pigs, making the pig transportation process smoother and more efficient, and adapting to the transportation specification requirements in large-scale breeding scenarios.

[0017] 2. During the application of this technical solution, by setting up guiding and corresponding detection mechanisms, pigs can be accurately guided to the detection area, ensuring that pigs pass through the detection points one by one in an orderly manner.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] An automatic counting device for penned pigs includes a base 1. Passage railings 2 are screwed onto the front and rear sides of the top of the base 1, forming a passageway between two passage railings 2. A locking and limiting mechanism 3 is fixedly installed at the top center of each passage railing 2. A shaft 4 is rotatably connected to the inner center of the locking and limiting mechanism 3. One-way gates 5 are fixedly installed in a ring at equal intervals on the outer surface of the shaft 4. A counting mechanism 6 is located at the output end of the passageway inside the passage railing 2 on the top of the base 1. A controller 7 is fixedly installed on the top of one passage railing 2. The one-way gates 5 are used to limit the pigs' movement in one direction. When a pig passes through, it squeezes the one-way gate 5, causing the shaft 4 to rotate. The rotation of the shaft 4 allows the pig to pass through the passageway. When the pig moves backward, the locking and limiting mechanism 3 prevents the shaft 4 on the one-way gate 5 from rotating in the opposite direction, thus preventing the pig from retreating.

[0027] The counting mechanism 6 includes a guide plate 61, which is screwed to the side of the passage railing 2 near the exit. A side arm 62 is fixedly installed on the outer side of the guide plate 61. A mounting side plate 63 is fixedly installed through the passage railing 2. An infrared beam sensor 64 is fixedly installed on the middle of the outer side of the mounting side plate 63. During the application of this device, by setting up the passage railing 2, locking and limiting mechanism 3, one-way guardrail gate 5, counting mechanism 6, and controller 7, the farmer can guide the pigs into the two passages. The passageway formed between the guardrails 2 provides a limited range for pig movement, preventing them from deviating from the path. As pigs move towards the exit end of the passageway, they press against the one-way gate 5 on the surface of the shaft 4, causing the shaft 4 to rotate inside the locking and limiting mechanism 3. This rotation allows the pigs to pass smoothly through the passageway. When a pig attempts to retreat, the locking and limiting mechanism 3 locks and limits the shaft 4, preventing it from rotating in the opposite direction and the one-way gate 5 from opening towards the entrance end of the passageway. This effectively prevents the pigs from retreating. When the output end moves, it enters the effective range of the guide plate 61 in the counting mechanism 6. The guide plate 61 guides the pigs, allowing them to pass orderly through the detection area of ​​the infrared beam sensor 64. The infrared beam sensor 64 is fixedly installed on the middle of the outer side of the mounting side plate 63. The mounting side plate 63 is fixedly connected to the guide plate 61 through the side arm 62. When a pig passes by, the infrared beam sensor 64 can detect the pig and transmit the signal to the controller 7. The controller 7 is fixedly installed on the top of a channel guardrail 2 and can process the detection signal and record the counting results. This design enables one-way passage during pig transfer, preventing contaminants from being brought into the farm due to backtracking. At the same time, through the guidance of the guide plate 61 and the detection of the infrared beam sensor 64, automatic counting of pigs is achieved, reducing the errors that may occur during manual counting, improving the accuracy of counting and the efficiency of transfer. It eliminates the need for frequent manual intervention, reducing the frequency of contact between personnel and pigs, and ensuring the smoothness of the transfer process, providing strong support for the biosecurity control and standardized management of pig farms.

[0028] Combination Figures 1-3As shown, a reserved notch is opened at the end of the channel guardrail close to the mounting side plate, the reserved notch is arranged in a circular shape and its position corresponds to the detection end of the infrared opposite-emitting sensor, and the two infrared opposite-emitting sensors realize the detection and counting of pigs through the reserved notch. The counting mechanism further comprises a top frame, the top frame is fixedly installed on the top of the locking limit mechanism, a connecting rod is fixedly installed on the side of the top frame close to the mounting side plate, and a laser ranging sensor is fixedly installed at the outer end of the connecting rod, the laser ranging sensor is used for detecting the height of passing pigs. The guide flow deflector is generally arranged in a herringbone shape, the guiding end of the guide flow deflector is disposed on the side close to the shaft body, and the guide flow deflector is used for guiding pigs to the center to ensure that they pass through the bottom of the laser ranging sensor in a concentrated manner to realize the height detection of pigs.

[0029] In the above technical solutions of the embodiments of the present application, during the application of the device, by providing the reserved notch, the top frame, the connecting rod, the laser ranging sensor and the guide flow deflector with a specific structure, in use, when pigs move towards the output end of the aisle, the guide flow deflector, with its overall herringbone structure and the guiding end close to the shaft body, can guide the pigs to the center to ensure the concentrated movement of the pigs. When the pigs are guided to the corresponding position in a centered manner, the reserved notch on the channel guardrail corresponds to the detection end of the infrared opposite-emitting sensor, and the two infrared opposite-emitting sensors detect the passing pigs without being blocked through the reserved notch, so as to realize accurate detection and counting of pigs. At the same time, the connecting rod on the top frame provides mounting support for the laser ranging sensor, and the pigs guided to the center will pass through the bottom of the laser ranging sensor in a concentrated manner, and the laser ranging sensor then completes the detection of the height of the passing pigs. This design allows the detection of the infrared opposite-emitting sensor not to be hindered by the channel guardrail, and cooperates with the centered guidance of the guide flow deflector, which greatly improves the accuracy of pig counting, avoids missed detection or false detection caused by pig deviation, and at the same time, the laser ranging sensor can synchronously obtain pig height data, which enriches the detection information, no additional manual measurement is required, which not only improves the overall efficiency of pig transfer and counting, but also provides more practical data for subsequent breeding management in the pig farm, making the whole counting process smoother, more convenient and with more comprehensive data.

[0030] Embodiment 2

[0031] In conjunction with Figures 1-3 and Figure 5As shown, the locking and limiting mechanism 3 includes a mounting plate 31, which is fixedly installed at the top center of the passageway guardrail 2. A shaft 4 is rotatably connected to the inner side of the mounting plate 31. A limiting module 32 is rotatably installed on the outer side of the mounting plate 31. The two ends of the shaft 4 are connected to the inner side of the limiting module 32 via couplings. The limiting module 32 is used to limit the shaft 4 to prevent reverse rotation and thus prevent pigs from backflowing. The limiting module 32 includes a ratchet 321 and a turntable 322. The ratchet 321 is rotatably connected to the middle outer side of the mounting plate 31. The two ends of the shaft 4 are connected to the inner side of the ratchet 321 via couplings. The turntable 322 is rotatably connected to the upper outer side of the mounting plate 31. A limiting arm is fixedly installed on the outer side of the turntable 322. 323, the lower end of the limiting arm 323 is fixedly connected to the limiting tooth cone 324, the limiting tooth cone 324 and the ratchet 321 are meshed and connected. The limiting tooth cone 324 can fall naturally under its own weight and mesh with the ratchet 321 to achieve the function of unidirectional transmission, preventing the pig from flowing back. A load-bearing plate 325 is fixedly installed on the outer side of the limiting arm 323 near the limiting tooth cone 324. A load-bearing ball 326 is fixedly installed on the outer side of the load-bearing plate 325. The outer side of the mounting plate 31 is covered with a covering shell. The covering shell is used to cover the limiting module 32 and can cover and protect the limiting structure such as the ratchet 321. The load-bearing ball 326 is used to provide power to the limiting tooth cone 324 to ensure that it sinks stably and meshes with the ratchet 321 to form the unidirectional rotation of the shaft 4.

[0032] The technical solution described in the above-described embodiments of this application, during the application of this device, is achieved by setting up an installation plate 31, a limiting module 32, a coupling, a load-bearing plate 325, a load-bearing ball 326, and a covering shell. This allows pigs to move towards the aisle output end and press against the one-way guardrail gate 5, thereby driving the shaft 4 to rotate. The shaft 4 drives the ratchet 321 to rotate synchronously via the coupling. During the rotation of the ratchet 321, it pushes up the limiting tooth cone 324 that meshes with it. The limiting tooth cone 324 rotates with the turntable 322, while the load-bearing ball 326 on the outside of the load-bearing plate 325 provides power to the limiting tooth cone 324, ensuring that it naturally falls back to its original position under gravity, continuously maintaining limiting engagement with the ratchet 321, thus achieving a one-way transmission function. When the pig attempts to... During reverse flow, the meshing structure between the limiting tooth cone 324 and the ratchet 321 restricts the ratchet 321 from rotating in the opposite direction, thus preventing the shaft 4 from rotating in the opposite direction and preventing the pigs from flowing back. At the same time, the outer casing of the mounting plate 31 covers and protects the limiting structure such as the ratchet 321, preventing external impurities from affecting the operation of the components. This design, through the cooperation of the mechanical structure, stably achieves the unidirectional rotation restriction of the shaft 4, effectively preventing the backflow behavior of pigs during the transfer process, reducing the risk of contaminant transmission caused by backflow, ensuring the unidirectional and orderly transfer process, and the setting of the casing extends the service life of the limiting module 32, making the locking and limiting function more stable and reliable, and helping the pig farm to control biosecurity and transfer efficiently.

[0033] The working principle and advantages of this utility model are as follows: During the application period, in the pig transfer and counting stage, the farmers guide the pigs into the passageway of this device. The passageway guardrail 2 defines a fixed path for the pigs to move, preventing them from deviating from the preset trajectory. When the pigs move towards the output end of the passageway, they will squeeze the one-way guardrail gate 5 on the surface of the shaft 4. This squeezing force drives the shaft 4 to rotate inside the mounting plate 31 of the locking and limiting mechanism 3. The mounting plate 31 provides stable support for the shaft 4 and the limiting module 32. When the shaft 4 rotates, it drives the ratchet 321 to rotate synchronously through the coupling. The turntable 322 of the limiting module 32 is rotatably connected to the mounting plate 31. The lower end of the limiting arm 323 on the outer side of the turntable 322 is fixedly connected to the limiting tooth cone 324. The limiting tooth cone 324 and the ratchet 321 are engaged. The outer end of the limiting arm 323 near the limiting tooth cone 324 is provided with A weighted disc 325 is placed, and the weighted ball 326 on the outer side of the weighted disc 325 provides a continuous downward force to the limiting tooth cone 324, ensuring that the limiting tooth cone 324 is always in close contact with the ratchet 321. When the ratchet 321 rotates forward with the shaft 4, the tooth surface of the ratchet 321 pushes up the limiting tooth cone 324. After the limiting tooth cone 324 rotates around the turntable 322, it quickly resets under the gravity of the weighted ball 326 and the weighted disc 325. This does not hinder the forward rotation of the shaft 4, and can also play a limiting role when the pig tries to retreat. If the pig retreats towards the aisle input end, it will squeeze the one-way guardrail 5 and drive the shaft 4 to try to rotate in the opposite direction. At this time, the meshing structure between the limiting tooth cone 324 and the ratchet 321 will restrict the ratchet 321 from rotating in the opposite direction. The shaft 4 will then be unable to rotate in the opposite direction, and the one-way guardrail 5 will be unable to open towards the aisle input end, thus preventing the pig from retreating.

[0034] As the pigs continue to move towards the aisle output end, they will enter the effective range of the guide plate 61. The guide plate 61 guides the pigs that have shifted to the sides of the aisle towards the center through its own structure, so that the pigs can move in a concentrated and orderly manner. The side arm 62 on the outer side of the guide plate 61 is fixedly connected to the mounting side plate 63. The infrared beam sensor 64 on the mounting side plate 63 corresponds to the reserved slot 65 of the aisle guardrail 2. The reserved slot 65 prevents the aisle guardrail 2 from blocking the infrared signal. When the pigs are accurately centered by the guide plate 61, they will pass through the detection area between the two infrared beam sensors 64 one by one. The moment the pig blocks the infrared signal, the infrared beam sensor 64 transmits the detection signal to the controller 7. The controller 7 automatically records a count data.

[0035] While the infrared beam sensor 64 is counting, the top frame 66 provides mounting support for the laser rangefinder sensor 68 via the connecting rod 67. The laser rangefinder sensor 68 is located above the middle of the aisle. Since the pigs have been precisely centered by the guide plate 61, they will accurately pass under the laser rangefinder sensor 68. The laser rangefinder sensor 68 emits a laser beam to the back of the pig, measures the real-time distance between itself and the pig's back, calculates the pig's height data, and then transmits the data synchronously to the controller 7 to realize the automatic detection and recording of the pig's height. The controller 7 uniformly receives and stores the counting data of the infrared beam sensor 64 and the height data of the laser rangefinder sensor 68, which is convenient for the farmers to query and count later.

[0036] This device, through the coordinated operation of its various structures, effectively prevents pigs from retreating during transport, avoiding the introduction of external contaminants into the farm by returning pigs, thus solving the biosecurity threat caused by backflow in the prior art. The guide plate 61 guides pigs to move in an orderly and centered manner, and with the precise detection and counting of the infrared beam sensor 64, it avoids duplicate counting or missed counting caused by disorderly movement of pigs, solving the drawback of poor counting accuracy. The combination of the channel guardrail 2 limiting the path and the guide plate 61 guiding orderly movement reduces the congestion of pigs in the passageway, eliminating the need for manual guidance and reducing the frequency of contact between personnel and pigs. At the same time, the laser ranging sensor 68 enriches the detection dimensions, providing more data support for breeding management. Overall, it realizes the integrated operation of one-way passage of pigs, automatic counting and height detection, adapting to the transportation needs of large-scale breeding.

[0037] During the application of this device, the fixed installation of each structure can be selected by bolt installation, welding installation, screw installation or some flexible snap-fit ​​installation. If a detachable design is required, bolt or screw installation can be selected. If a stable installation is required, welding installation can be selected. The specific requirements can be flexibly selected according to the application requirements.

[0038] During application of this technical solution, the controller 7 is an STM32F103 series microcontroller, installed on top of the guardrail 2 in an easily accessible position. The controller 7 integrates a 1.8-2.4 inch LCD display. The infrared beam sensor 64 is an E3Z-T61 series with a detection distance of 5-50cm. The laser rangefinder sensor 68 is a TF-Luna series with a range of 0.1-8m and an accuracy of ±1mm. The circuit system uses DC12-24V power supply. External power modules supply power to the controller 7, infrared beam sensor 64, and laser rangefinder sensor 68 via power lines. The signal output terminals of the infrared beam sensor 64 and laser rangefinder sensor 68 are connected to the I / O interface of the controller 7 via signal lines. The display signal terminal of the controller 7 is directly soldered to its own display module to achieve real-time reception and display of detection data. If electric control of the unidirectional guardrail is required... The gate 5 can be equipped with a 24V DC geared motor. The motor is equipped with a planetary gearbox (reduction ratio 10-50:1) and an incremental encoder (resolution 100-500 lines). The motor is connected to the controller 7 through an L298N drive module. The controller 7 outputs signals to regulate the motor's operation, achieving precise speed adjustment and rotation angle control of the shaft 4. During use, a microwave radar sensor can be installed at the entrance of the passage to detect whether pigs have entered the passage and trigger counting preparation, a Hall sensor can be installed at the locking limit mechanism 3 to monitor the rotation status of the shaft 4, a pressure sensor can be installed on the passage floor to help confirm the pigs' passage status, and a temperature and humidity sensor can be installed inside the passage guardrail 2 to monitor the breeding environment parameters. All these sensors are connected to the controller 7 through signal lines to improve counting accuracy and device operation stability. Installation and application can be selected according to requirements.

[0039] The scope of protection of this application does not involve improvements to the electronic components of the device or equipment. Therefore, the working principles of each electronic component are not described in detail here. The electronic components in this application are all conventional electronic components used in the prior art. They are all conventional technical means in the prior art, and the application of the prior art is very mature. Therefore, they will not be elaborated here.

[0040] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
