Description

Technical Field

[0001] This utility model belongs to the technical field of livestock breeding equipment, specifically a modular calf care device. Background Technology

[0002] In the development of calf farming technology, various calf care devices have been widely used. However, these products still have some problems in practical use. Currently, calf care devices on the market are usually fixed in place, making them difficult to disassemble and move, and thus hard to adapt to farms of different sizes and site conditions. This results in some farms being unable to flexibly adjust their existing care devices when adjusting the scale of farming or changing the site layout, increasing management costs and operational inconvenience.

[0003] To improve performance, some manufacturers have attempted to increase flexibility by adding modular designs. However, such improvements often suffer from unstable connections between modular components and complex assembly and disassembly, resulting in poor overall system stability and ease of operation, as well as high maintenance costs.

[0004] A search revealed a movable and easy-to-clean calf island design, publication number CN113748993B, dated November 29, 2022. This design utilizes tracks and a sliding frame, allowing for easy movement and disassembly of the calf island for cleaning. However, this design has the following problems in practical applications: 1. The complex structure of the tracks and sliding frame increases the manufacturing cost and maintenance difficulty of the device; 2. The movement and disassembly process requires manual operation, which is inconvenient, especially in large-scale farms, resulting in a large workload; 3. The sliding frame is prone to displacement during use, affecting the calves' living environment.

[0005] A search revealed a calf island design with publication number CN116195519B, published on August 20, 2024. This design includes a heating base, a sand trough, and a cleaning and disinfection device, enabling rapid cleaning and disinfection of the calf island. However, this design has the following problems in practical applications: 1. The complex structure of the cleaning and disinfection device increases manufacturing costs and maintenance difficulty; 2. While the heating base and sand trough design provide a certain level of comfort, the sand trough easily accumulates dirt during long-term use, requiring frequent cleaning; 3. This device mainly relies on manual operation for cleaning and disinfection, cannot be automated, and has low efficiency.

[0006] The aforementioned problems indicate that traditional calf care devices currently on the market are insufficient to effectively address the flexible adjustment needs arising from varying farming scales and site conditions. Therefore, this invention provides a modular calf care device that adapts to changes in farming scale, overcoming these shortcomings and offering a more flexible, efficient, and adaptable solution to changing environments.

[0036] like Figures 1 to 6 As shown, this utility model provides a modular calf care device, which includes a main frame 1 and multiple modular units 2 horizontally arranged within the main frame 1. Fixed supports 3 are symmetrically arranged on both sides of the main frame 1, and casters 4 are installed at the bottom of the fixed supports 3. The casters 4 allow the entire device to be easily moved between different locations, adapting to farms of different sizes and site conditions. Automatic doors 5 are installed at the feed inlet and outlet of the main frame 1, respectively. The automatic doors 5 are fixedly connected to the surface of the main frame 1, and several sensors 6 are fixedly connected inside. The upper surfaces of the sensors 6 are flush with the corresponding upper surfaces of the main frame 1. Sensors 7 are positioned above the corresponding sensors 6. Several second motors 8 are installed on the surface of the main frame 1, and the output shafts of the second motors 8 are fixedly connected to the sensors 7. When a calf enters or exits the main frame 1, the sensor 7 detects the calf and sends a signal to the second motor 8. The second motor 8 drives the automatic door 5 to open or close, realizing automatic control of calf entry and exit, while simultaneously isolating the environment inside the main frame 1 to prevent external factors from interfering with the calf's life.

[0037] The main frame 1 contains several connecting modules 9. Connecting locks 10 are installed between adjacent connecting modules 9, securing multiple module units 2 into a single unit. The connecting locks 10 located at the feed inlet and outlet of the main frame 1 isolate the calves from the external environment, preventing escape. Rectangular grooves 11 are formed on the surface of the connecting modules 9. Several buckles 12 are symmetrically arranged on the upper part of the rectangular grooves 11. The buckles 12 are slidably connected to the connecting modules 9 via second rectangular grooves 13 inside the rectangular grooves 11. Several second springs 14 are installed within the second rectangular grooves 13. The two ends of each second spring 14 are fixedly connected to the connecting module 9 and the buckles 12, respectively. A third sensor 15 is installed at the end of the connecting module 9 and is fixedly connected to the inner wall of the main frame 1. When multiple module units 2 need to be combined, the connecting modules 9 achieve quick connection and fixation through the cooperation of the buckles 12 and the second springs 14. When disassembly is required, the buckles 12 automatically pop out after the third sensor 15 detects a disassembly signal, facilitating the disassembly of the module unit 2.

[0038] A connecting block 16 is fixedly connected to the inner wall of the main frame 1. A slide rail 17 is fixedly connected to the surface of the connecting block 16. A slider 18 is slidably connected to the surface of the slide rail 17. A connecting rod 20 is rotatably connected to the surface of the slider 18 via a second bearing 19. A connecting module 9 is fixedly connected to the surface of the slider 18. Multiple pulleys 21 are provided inside the slider 18, distributed on the four sides of the slide rail 17. The pulleys 21 are rotatably connected inside the slider 18 via a fixed rod 22 and a third bearing 23. The design of the slide rail 17 and slider 18 allows the connecting module 9 to slide freely inside the main frame 1, facilitating the adjustment of the positions between different module units 2 and adapting to farms of different sizes. The pulleys 21 make the sliding process smoother, reduce frictional resistance, and improve operational convenience.

[0039] Multiple support frames 24 are installed on the upper part of the main frame 1. A heating lamp 25 and an ultraviolet lamp 26 are mounted on the top of each support frame 24. The irradiation area of ​​the heating lamp 25 and ultraviolet lamp 26 inside the main frame 1 is adjusted by extending and retracting the support frame 24. Figure 2 As shown, a support plate 27 is positioned between two adjacent support frames 24, with the support frames 24 mounted on the surface of the support plate 27. The surface of the support plate 27 is mirrored to enhance lighting and improve the care quality for calves. The telescopic adjustment of the support frames 24 is achieved through a telescopic motor housed within them. The control signal of the telescopic motor is adjusted by a controller according to the actual needs of the calves, ensuring that the calves receive suitable light and temperature conditions at different growth stages.

[0040] The upper part of the main frame 1 is symmetrically equipped with an air inlet box 28 and an air outlet box 29, such as... Figure 3As shown, ultraviolet lamps 26 are embedded in the surface of the air inlet box 28. Air from outside the main frame 1 is drawn into the air inlet box 28 and blown towards the inside of the main frame 1 near the discharge port, cooling the ultraviolet lamps 26 and forming an air curtain to prevent heat from escaping from the inside of the main frame 1. An air inlet box 28 is located on one side of the exhaust box 29. Several first air curtain machines 30 are embedded inside the exhaust box 29. A baffle plate 31 is provided between two adjacent first air curtain machines 30, and the baffle plate 31 is fixedly connected to the exhaust box 29. The air inlet box 28 and the exhaust box 29 are internally connected. The cooling box 32 is connected to the air inlet of the exhaust box 29 via a pipe, and the heating box 33 is connected to the air outlet of the heating lamp 25 via a pipe. Second air curtain machines 34 are installed inside the feed inlet of the main frame 1, and the air inlets of the second air curtain machines 34 are connected to the inside of the exhaust box 29 via pipes. By setting up the first air curtain machine 30 and the second air curtain machine 34, multiple air curtains are formed, which further enhances the heat insulation and escape prevention effects, while maintaining air circulation inside the main frame 1 and improving the quality of the calf's living environment.

[0041] The connecting lock 10 and the third sensor 15 are fixedly connected to the inner wall of the main frame 1. The connecting lock 10 located at the feed inlet and feed outlet of the main frame 1 is made of opaque material to prevent external light from interfering with the calves and to maintain a stable living environment for the calves. The connecting lock 10 located inside the main frame 1 is made of transparent material, which facilitates monitoring the calves' living conditions and does not affect the irradiation effect of the ultraviolet lamp 26. The top of the main frame 1 is provided with a mounting plate 35, and the heating lamp 25 and ultraviolet lamp 26 are installed in the mounting groove 36 opened on the surface of the mounting plate 35. The upper part of the main frame 1 is symmetrically provided with a heating mounting box 37 and a cooling mounting box 38. Several heating boxes 33 are embedded in the surface of the heating mounting box 37, and several cooling boxes 32 are embedded in the surface of the cooling mounting box 38. Small holes 39 are evenly opened on the side of the exhaust box 29 near the air inlet box 28. The interior of the cooling box 32 is connected to the interior of the exhaust box 29 through pipes. The installation of heating box 33 and cooling box 32 allows for precise control of temperature and humidity inside the main frame 1, improving the living comfort of calves.

[0042] The main frame 1 houses a tray 40, with flanges 41 along its outer edge. Protruding columns 42 are evenly fixedly connected inside the tray 40. Drainage holes 43 are evenly distributed on the side walls of the tray 40. Several water-guiding grooves 44 and water-gathering grooves 45 are formed on the surface of each support plate 27. A connecting block 46 connects adjacent water-gathering grooves 45 and is fixedly connected to both support plates 27. The tray 40 is used to collect calf waste. The flanges 41 prevent waste from overflowing. The drainage holes 43 and water-guiding grooves 44 allow liquid waste to drain smoothly from the tray 40. The water-gathering grooves 45 and connecting blocks 46 allow for concentrated collection of liquid waste, facilitating cleaning. The surface of the tray 40 is also mirrored to enhance lighting and improve the calf's living environment.

[0043] The working principle and operation process of this modular calf care device are as follows:

[0044] First, the modular calf care device is moved to the desired farm location. The device can be easily moved to the designated location using the fixed supports 3 on both sides of the main frame 1 and the casters 4 at the bottom. Multiple modular units 2 are combined into a single unit via connecting modules 9 and connecting locks 10. The connecting locks 10 automatically lock and unlock under the control of the third sensor 15, ensuring the stability of the connection between the modular units 2 and the ease of disassembly.

[0045] When a calf enters the main frame 1, sensors 6 and 7 inside the automatic door 5 detect its entry. Sensor 6 detects the calf's body shape and position, while 7 detects the calf's specific entry and exit movements, transmitting signals to the second motor 8. The second motor 8 then drives the automatic door 5 to open. After the calf enters the main frame 1, the automatic door 5 closes under the control of the sensor 7, isolating the environment inside the main frame 1 and preventing interference from external factors. Simultaneously, the closing signal of the automatic door 5 is transmitted to the heating lamp 25 and ultraviolet lamp 26 via the controller, activating the heating lamp 25 and ultraviolet lamp 26 to provide suitable light and temperature conditions for the calf.

[0046] The support frame 24 inside the main frame 1 is telescopically adjustable via a telescopic motor, adjusting the irradiation areas of the heating lamps 25 and ultraviolet lamps 26 according to the actual needs of the calf. For example, in the early stages of calf development, when the temperature is low, more heating lamps 25 are needed; as the calf grows, the temperature requirement gradually decreases, and the number of heating lamps 25 can be appropriately reduced while the number of ultraviolet lamps 26 is increased to meet different growth needs. The telescopic adjustment of the support frame 24 is automatically controlled by a controller. The controller adjusts the position of the support frame 24 based on real-time data provided by sensors 6 and 7, ensuring that the calf receives optimal environmental conditions at different growth stages.

[0047] The air inlet box 28 and air outlet box 29 inside the main frame 1 form an air curtain through an air curtain machine to maintain a stable internal environment. Ultraviolet lamps 26 are embedded in the surface of the air inlet box 28. Air from outside the main frame 1 is drawn into the air inlet box 28 and blown towards the inside of the main frame 1 near the discharge port by the first air curtain machine 30. During this process, the air cools the ultraviolet lamps 26, preventing them from overheating and affecting their lifespan. Simultaneously, the first air curtain machine 30 and the second air curtain machine 34 form an air curtain to prevent heat from escaping from the main frame 1, maintaining a warm and stable living environment for the calves. The cooling box 32 is connected to the air inlet of the exhaust box 29 through a pipe, expelling the cooled air and maintaining airflow circulation inside the main frame 1. The heating box 33 is connected to the air outlet of the heating lamp 25 through a pipe, delivering heated air into the main frame 1 to further improve the comfort of the calves.

[0048] When calves need to excrete waste, the tray 40 effectively collects their excrement. The outer edge of the tray 40 has flanges 41 to prevent waste from overflowing. Protruding posts 42 are evenly and fixedly connected inside the tray 40, preventing calves from slipping and increasing the tray's load-bearing capacity. Drainage holes 43 are evenly distributed on the side walls of the tray 40, and several water guide channels 44 are formed on the surface of the support plate 27, allowing liquid waste inside the tray 40 to drain smoothly through the drainage holes 43 and water guide channels 44. The design of the water collection trough 45 and connecting block 46 allows for centralized collection of liquid waste, facilitating regular cleaning. The surface of the tray 40 is mirrored to enhance light penetration and improve the calf's living environment.

[0049] When a calf needs to leave the main frame 1, sensors 6 and 7 inside the automatic door 5 detect the calf's departure. Sensor 6 detects the calf's body shape and position, and 7 detects the calf's specific departure action, transmitting a signal to the second motor 8. The second motor 8 then drives the automatic door 5 to open. After the calf leaves the main frame 1, the automatic door 5 closes under the control of sensor 7, restoring the isolation state of the internal environment of the main frame 1. Simultaneously, the controller automatically adjusts the on / off status of the heating lamp 25 and ultraviolet lamp 26 based on the calf's departure information, ensuring that the internal environment of the main frame 1 remains suitable after the calf leaves.

[0050] When the heating lamp 25 and ultraviolet lamp 26 inside the main frame 1 require maintenance, the telescopic adjustment function of the support frame 24 can easily move the heating lamp 25 and ultraviolet lamp 26 to the edge or bottom of the main frame 1 for replacement or repair. The operator can control the telescopic motor through the controller to adjust the support frame 24 to a position that is easy to operate without disassembling the entire module unit 2, saving maintenance time and costs.

[0051] Furthermore, the modular design of module unit 2 allows the entire device to be flexibly adjusted according to the actual needs of the farm. For example, when the farm expands, more module units 2 can be added, and they can be quickly combined by connecting module 9 and connecting lock 10. When the farm shrinks or the layout needs to be adjusted, the excess module units 2 can be easily disassembled and recombined into a new structure to adapt to different farming scales and site conditions.

[0052] In summary, this modular calf care device, through its modular design, allows for easy disassembly and relocation, adapting to farms of different sizes and site conditions, reducing management costs and operational inconvenience. The use of automatic doors 5 and sensors 7 enables automatic control of calf entry and exit, improving operational convenience. The telescopic adjustment of the support frame 24 allows the heating lamp 25 and ultraviolet lamp 26 to be adjusted according to the actual needs of the calves, improving care effectiveness. The air curtain design of the air inlet box 28 and exhaust box 29 ensures airflow within the device while reducing heat loss, improving energy efficiency. The tray 40 effectively collects calf excrement, maintaining a clean living environment and improving calf growth quality.
