Description

Technical Field

[0001] This utility model relates to the field of calf measurement technology, and in particular to a calf measuring device. Background Technology

[0002] In modern ranch management, regular and accurate calf health monitoring is crucial for ensuring healthy calf growth and improving farming efficiency. The growth and development of calves directly impacts future milk production, meat quality, and overall farming costs in adult cattle. Therefore, accurately obtaining various calf health indicators, such as height, shoulder height, and weight, is essential for ranches to develop scientific and reasonable feeding plans, disease prevention strategies, and breeding programs. Currently, the traditional calf health monitoring devices widely used in ranches are primarily designed to meet basic health monitoring needs. These devices typically consist of core components such as a concave plate, weighing sensors, a weighing plate, a fence, and an external display screen. The concave plate serves as the supporting frame for the entire measuring device, providing a stable mounting base for other components. The weighing sensor is a key element for accurately measuring calf weight, converting the pressure applied by the calf to the weighing plate into an electrical signal, which is then processed to derive the weight value. The weighing plate, located at the center of the concave plate, is the platform where the calf stands directly for weight measurement. The enclosure is designed to guide and limit the calf's range of movement, ensuring it remains in the appropriate position on the weighing plate during measurement, thus improving accuracy. The external display screen is used to display the measured data in real time, facilitating recording and analysis by farm staff.

[0003] In actual calf weighing operations, especially weight measurement, staff usually need to drive the calf onto the weighing plate of the weighing device. For some younger calves or those with limited mobility, staff may even need to carry them to the designated location. However, due to the physiological characteristics of calves, unexpected situations often occur during the weighing process, with calves urinating on the weighing plate being one of the more common problems. Because of the limitations in the structural design of traditional weighing devices, gaps inevitably exist between the concave plate and the weighing plate. When a calf urinates on the weighing plate, the urine can easily flow into the concave plate through these gaps.

[0004] Once urine enters the concave plate, it can easily come into contact with the load cells installed within. As high-precision electronic components, load cells have stringent requirements for their working environment. Their internal electronic circuitry and sensitive elements are highly susceptible to corrosion from moisture, impurities, and chemicals in urine. Urine intrusion can cause short circuits and component corrosion in the load cells, affecting their normal operation and leading to inaccurate measurement data or even complete failure. This not only causes significant disruption to the daily management of the farm but may also result in the inability to promptly ascertain the true weight of calves, leading to the development of inappropriate feeding plans and negatively impacting the calves' growth and development. Utility Model Content

[0005] The purpose of this invention is to address the problem in existing technologies where workers typically need to herd calves onto the weighing plate of the weighing device. For younger, less mobile calves, workers may even need to carry them to a designated location. However, due to the physiological characteristics of calves, unexpected situations often arise during the weighing process, with calves urinating on the weighing plate being a common problem. Because of limitations in the structural design of traditional weighing devices, gaps inevitably exist between the concave plate and the weighing plate. When a calf urinates on the weighing plate, the urine can easily flow into the concave plate through these gaps.

[0006] Once urine enters the concave plate, it can easily come into contact with the load cell installed within. As a high-precision electronic component, the load cell has stringent requirements for its working environment. Its internal electronic circuitry and sensitive elements are highly susceptible to corrosion from moisture, impurities, and chemicals in urine. Urine intrusion can cause short circuits and component corrosion in the load cell, thus affecting its normal operation and leading to inaccurate measurement data or even complete failure. This not only causes significant disruption to the daily management of the farm but may also result in the inability to promptly ascertain the calf's true weight, leading to the development of inappropriate feeding plans and negatively impacting the calf's growth and development. Therefore, a calf weighing device was proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A calf weighing device includes a concave base and a weighing sensor for weighing calves. The concave base is concave, and the bottom of the weighing sensor is fixedly connected to the inner wall of the bottom of the concave base. A weighing plate is slidably connected to the inner wall of the concave base, and the bottom of the weighing plate contacts the top of the weighing sensor. Side rails I and II are fixedly provided on the top two sides of the concave base, respectively. Doors are installed on one side of each end of side rail II via hinges. A flow preventer is provided on the weighing plate to prevent calf urine from flowing into the concave base through the gap between the concave base and the weighing plate.

[0009] To prevent overflow, the drain plug also includes an overflow prevention mechanism, which allows excess urine to be drained when there is too much urine inside.

[0010] In one possible design, the flow preventer includes a baffle plate and three limiting strips for preventing the baffle plate from moving on the weighing plate. The bottom of each of the three limiting strips is welded to the top of the weighing plate. The bottom of the baffle plate has three slots. The baffle plate is placed on the weighing plate, and the limiting strips are inserted into the slots. The top of the baffle plate is concave.

[0011] In one possible design, the overflow prevention mechanism includes an overflow pipe and a housing. The overflow pipe is located on one side of the baffle plate, and one side of the housing is fixedly connected to one side of the concave seat. A connecting pipe for discharge is fixedly provided on one side of the housing and is connected to it. One end of the overflow pipe is located above the housing.

[0012] In one possible design, long insert plates are welded to one side of both ends of the side panel I, and short insert plates are welded to one side of the door body. Both the long and short insert plates have slots, and the same pin is inserted into both slots. The pin is L-shaped.

[0013] In one possible design, a discharge hole is provided on one side of the baffle plate, and an internal thread is provided inside the discharge hole. An external thread is provided on the outer side of one end of the overflow pipe, and the overflow pipe is threadedly connected to the discharge hole.

[0014] In one possible design, a fixing ring is fixedly sleeved on the outer side of one end of the overflow pipe, and a sealing ring for improving the sealing between the fixing ring and the baffle plate is fixedly provided on one side of the fixing ring, and anti-slip texture is provided on the overflow pipe.

[0015] In this application, when guiding a calf into the weighing device for physical testing, the worker holds the latch and pulls it out of the sockets of the long and short plates. Because the latch is L-shaped, it is easy for the worker to grip and operate. After pulling out the latch, the door can rotate freely around the hinge connected to side rail II. At this time, the door is pushed outward to open the entrance of the weighing device (the other door is closed). The worker gently guides the calf into the weighing device, using food or soft calls to encourage the calf to voluntarily enter the space enclosed by side rail I, side rail II, and the door, and stand on the barrier plate on the weighing plate. Side railings I and II restrict the calf's movement, ensuring it stands in a suitable position for weighing. The gate is then closed, its hinges rotating and simultaneously moving a short latch. When the gate is fully closed, the short latch aligns with the long latch. A pin is then inserted to secure the gate. Once the calf stands on the railings, its weight is applied to the weighing plate, which transmits pressure to a load cell at the bottom. The load cell converts the pressure signal into an electrical signal and transmits it to an external display device, showing the calf's weight. The operator can then accurately measure the weight. This data should be accurately recorded for subsequent breeding management analysis. During the weighing process, if the calf urinates on the weighing plate, the baffle will act as a barrier. Because the top of the baffle is concave, the urine will accumulate in the concave area of ​​the baffle, preventing urine from flowing directly into the concave seat from the gap between the concave seat and the weighing plate. This protects the weighing sensor and other electronic components inside the concave seat from urine corrosion. When too much urine accumulates in the baffle, it will flow into the overflow pipe through the drain hole on one side of the baffle. The urine then flows into the box inside the overflow pipe, which serves as a temporary storage box for urine. When it is necessary to clean the urine... Workers can drain urine through a connecting pipe fixed on one side of the box. The connecting pipe can be connected to a suitable drain pipe or collection container (the connecting pipe has a connecting flange for connecting to external pipes). Since one end of the overflow pipe is connected to the baffle plate by threads, the connection is tight and easy to disassemble and clean. The fixing ring and its sealing ring further improve the sealing of the connection and prevent urine leakage (the fixing ring will press against the baffle plate and squeeze the sealing ring during the tightening of the overflow pipe). Since the baffle plate is placed on the weighing plate, it can be easily removed for cleaning. It should be noted that the overflow pipe needs to be removed before removing the baffle plate.

[0016] The beneficial effects of this utility model are as follows:

[0017] In this invention, a calf weighing device utilizes a flow preventer and an overflow prevention mechanism. The top of the flow preventer's baffle plate is concave, effectively blocking calf urine and causing it to accumulate within the concave area, preventing urine from flowing into the concave seat and contacting the weighing sensor. When there is excessive urine in the baffle plate, the overflow pipe of the overflow prevention mechanism can drain the urine into a storage box, preventing urine accumulation and overflow from damaging the weighing device again. This design effectively solves the problem of urine erosion, ensures the normal operation of the weighing sensor, guarantees the accuracy of calf weight measurement data, provides a reliable basis for farms to formulate reasonable feeding plans, and is beneficial to the growth and development of calves.

[0018] In this invention, a calf weighing device is placed on a weighing plate via a baffle plate and secured by three limiting strips. The baffle plate can be easily removed for cleaning. However, before removing the baffle plate, the overflow pipe must be disconnected. One end of the overflow pipe is threaded to the baffle plate, ensuring a tight connection and easy disassembly. The retaining ring and its sealing ring press against the baffle plate during the tightening of the overflow pipe, further improving the sealing performance and preventing urine leakage. This flexible structural design allows workers to easily clean the baffle plate and overflow pipe, removing residual urine and dirt, ensuring the hygiene of the weighing device, extending its service life, and reducing farm operating costs.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In one embodiment: Refer to Figure 1-4 A weighing device includes: a concave base 1, a weighing sensor, a weighing plate 11, side rails I 2, side rails II 3, a door 4, a spill preventer, and an overflow prevention mechanism. These components work together to accurately measure the weight of calves, while effectively solving the problem of urine eroding the internal components of the weighing device during calf weighing. The concave base 1 has a concave structure, providing a stable support frame for the entire weighing device. The bottom of the weighing sensor is fixedly connected to the bottom inner wall of the concave base 1 with bolts, ensuring that the weighing sensor is firmly installed and can accurately sense the pressure transmitted by the weighing plate 11 above.

[0026] The weighing plate 11 is slidably connected to the inner wall of the concave seat 1. This design allows the weighing plate 11 to move smoothly downwards when subjected to pressure from the calf, accurately transmitting the pressure to the weighing sensor at the bottom. The bottom of the weighing plate 11 is in close contact with the top of the weighing sensor, ensuring timely and accurate pressure transmission. Side rails I2 and II3 are fixedly installed on both sides of the top of the concave seat 1, respectively. The side rails restrict the calf's range of motion, ensuring that the calf stands in a suitable position during the weighing process, thus improving the accuracy of the measurement.

[0027] Both ends of side panel II3 are hinged to door bodies 4, which can rotate freely around the hinges to open and close the measuring instrument inlet. Long insert plates 7 are welded to one side of both ends of side panel I2, and short insert plates 6 are welded to one side of door body 4. Both long insert plates 7 and short insert plates 6 have slots into which the same L-shaped pin 5 is inserted. When door body 4 is closed, the short insert plate 6 aligns with the slot of the long insert plate 7, and the pin 5 is inserted into the slot to secure door body 4, preventing it from accidentally opening during weighing. The L-shaped pin 5 design makes it easy for operators to grip and operate, improving ease of use.

[0028] A flow preventer is installed on the weighing plate 11, primarily to prevent calf urine from flowing into the concave seat 1 through the gap between the concave seat 1 and the weighing plate 11. The flow preventer includes a baffle plate 10 and three limiting strips 12. The bottoms of the three limiting strips 12 are welded to the top of the weighing plate 11, fixing the position of the baffle plate 10. The bottom of the baffle plate 10 has three slots. When the baffle plate 10 is placed on the weighing plate 11, the limiting strips 12 are inserted into the slots, preventing the baffle plate 10 from moving on the weighing plate 11. The top of the baffle plate 10 is concave; this design allows calf urine to accumulate within the concave area of ​​the baffle plate 10, preventing urine from flowing everywhere.

[0029] To prevent overflow due to excessive urine in the overflow preventer, an overflow prevention mechanism is installed. This mechanism includes an overflow pipe 9 and a housing 8. The overflow pipe 9 is located on one side of the baffle plate 10. When the urine accumulated in the baffle plate 10 exceeds a certain amount, the urine will flow out through the overflow pipe 9. One side of the housing 8 is fixedly connected to one side of the concave seat 1 with bolts. One end of the overflow pipe 9 is located above the housing 8, allowing the urine flowing out of the overflow pipe 9 to flow smoothly into the housing 8 for storage. A connecting pipe 15 for discharge is fixedly installed on one side of the housing 8 and is connected to it. The connecting pipe 15 has a connecting flange for easy connection to an external drain pipe or collection container. When it is necessary to clean the urine in the housing 8, the urine can be discharged through the connecting pipe 15.

[0030] This application is for the field of calf testing, but can also be used in other fields applicable to this application.

[0031] In another embodiment: Reference Figure 1-4 A calf measuring device, used in the field of calf measurement.

[0032] A discharge hole is provided on one side of the baffle plate 10, and an internal thread 13 is provided inside the discharge hole. An external thread is provided on the outer side of one end of the overflow pipe 9. The overflow pipe 9 and the discharge hole are tightly connected by the threaded connection. This connection method is not only tight, but also easy to disassemble and install, and facilitates cleaning and maintenance of the overflow pipe 9 and the baffle plate 10. A fixing ring 14 is fixedly fitted on the outer side of one end of the overflow pipe 9. A sealing ring is fixedly provided on one side of the fixing ring 14. During the tightening of the overflow pipe 9, the fixing ring 14 will press against the baffle plate 10, thereby improving the sealing between the fixing ring 14 and the baffle plate 10 and preventing urine leakage. In addition, the overflow pipe 9 is provided with anti-slip texture, which increases the friction for operators when installing and disassembling the overflow pipe 9, making operation easier.
