Description

Technical Field

[0001] This utility model relates to the field of auxiliary products for animal husbandry, and in particular to a device for preventing lambs from crossing fences. Background Technology

[0002] In large sheep farms, ewes and their lactating lambs are typically managed in the same pen. The commonly used pen structure consists of a fenced enclosure at the front, with a fixed feeding trough installed outside the fence. During feeding, the farmer pours feed directly into the trough. The ewes, due to their size, can easily extend their heads through the fence gaps to eat. However, this conventional design has significant drawbacks. Because the gaps between the fence bars or mesh are usually designed to be relatively large, small, active lambs can easily squeeze through or jump out of the pen. Escaping lambs often jump directly onto the feeding trough to occupy a spot, which not only hinders the normal eating of other sheep and disrupts the feeding order, but more seriously, it causes the lambs to roam freely outside the pen. This disorderly activity greatly increases the difficulty and complexity of feeding and management. Feeders need to frequently drive away or capture stray lambs, which not only consumes a lot of manpower, but also poses risks of lambs getting lost, injured or causing other accidents, which has an adverse impact on the healthy growth of lambs and the overall management efficiency of the farm. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a lamb anti-crossing restriction device, which can prevent lambs from jumping out of the pen and reduce feeding and management costs.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A lamb anti-crossing restraint device includes a first electromagnetic chuck assembly, a second electromagnetic chuck assembly, a collar, magnets, a Hall sensor, and a wireless driving device. The first and second electromagnetic chuck assemblies are respectively mounted on the lamb's left and right forelegs. The collar is worn around the lamb's neck. The magnets are mounted on the horizontal bars of the sheep pen fence. The Hall sensor and the wireless driving device are electrically connected and both are mounted on the collar. The Hall sensor senses the magnet signal when the lamb's head extends beyond the fence and triggers the wireless driving device to send driving signals to the first and second electromagnetic chuck assemblies, causing them to conduct electricity and magnetically attract each other.

[0006] In some embodiments, the first electromagnetic chuck assembly includes a first battery, a first iron core, a first coil wound on the first iron core, a first receiver, and a first controller. The positive terminal of the first coil is electrically connected to the positive terminal of the first battery, and the negative terminal is electrically connected to the negative terminal of the first battery. The signal output terminal of the first receiver is electrically connected to the signal input terminal of the first controller. The power control terminal of the first controller is connected in series in the circuit between the first coil and the first battery. The power input terminal of the first controller is electrically connected to the positive and negative terminals of the first battery. The second electromagnetic chuck assembly includes a second battery, a second iron core, a second coil wound on the second iron core, a second receiver, and a second controller. The positive terminal of the second coil is electrically connected to the negative terminal of the second battery, and the negative terminal is electrically connected to the positive terminal of the second battery. The signal output terminal of the second receiver is electrically connected to the signal input terminal of the second controller; the power control terminal of the second controller is connected in series in the circuit of the second coil and the second battery; the power input terminal of the second controller is electrically connected to the positive and negative terminals of the second battery; the wireless driving device includes a transmitter and a driving battery; the collar is provided with a mounting shell, and connecting rings are provided on both sides of its outer surface; the mounting shell is mounted on the collar through the connecting rings; the Hall sensor, the transmitter, and the driving battery are all disposed inside the mounting shell; the signal output terminal of the Hall sensor is electrically connected to the signal input terminal of the transmitter; the wireless signal output terminal of the transmitter is wirelessly connected to the signal receiving terminals of the first receiver and the second receiver respectively; the positive and negative terminals of the driving battery are electrically connected to the power input terminals of the Hall sensor and the transmitter respectively.

[0007] Compared with existing technologies, this invention achieves at least the following beneficial effects: This invention uses a Hall sensor to sense the fence magnet and trigger a wireless signal, controlling the electromagnetic chucks on the lamb's left and right front legs to pass a reverse current to generate a strong magnetic attraction, instantly attracting and closing the lamb's legs, precisely preventing the lamb from jumping out of the fence gaps; the device is automatically activated only when the lamb's head extends out of the fence to eat, and is released when the head is retracted into the fence or away from it, ensuring the lamb's normal freedom of movement within the pen while effectively eliminating the risk of lambs jumping over feeding troughs or running around, maintaining the order of the ewe's feeding, and significantly reducing the difficulty and cost of manual herding and management.

[0021] refer to Figure 2 or Figure 3Specifically, the first electromagnetic chuck assembly 1 further includes a first mounting base 16 and a first fixing strap 17. The first mounting base 16 includes a first vertical plate 161 and a first cylinder 162. The first vertical plate 161 is vertically attached to the side of the lamb's left foreleg. The first cylinder 162 is vertically connected to the side of the first vertical plate 161. The first battery 11, the first iron core 12, the first coil 13 wound on the first iron core 12, the first receiver 14, and the first controller 15 are all disposed inside the first cylinder 162. The first fixing strap 17 includes two sets, each set having two straps. The two first fixing straps 17 are disposed at the two ends of the first vertical plate 161. By tightening the two sets of first fixing straps 17, the first mounting base 16 can be securely mounted on the lamb's left foreleg. The second electromagnetic chuck assembly 2 also includes a second mounting base 26 and a second fixing strap 27. The second mounting base 26 includes a second vertical plate 261 and a second cylinder 262. The second vertical plate 261 is vertically attached to the side of the lamb's right foreleg. The second cylinder 262 is vertically connected to the side of the second vertical plate 261. The second battery 21, the second iron core 22, the second coil 23 wound on the second iron core 22, the second receiver 24, and the second controller 25 are all disposed inside the second cylinder 262. The second fixing strap 27 includes two sets, each set having two straps. The two second fixing straps 27 are disposed at the two ends of the second vertical plate 261. By tightening the two sets of second fixing straps 27, the second mounting base 26 can be securely mounted on the lamb's right foreleg. In this embodiment, the ends of the first mounting base 16 and the second mounting base 26 with iron cores are respectively facing each other and symmetrically arranged. This arrangement ensures that the two electromagnetic chuck assemblies can generate magnetic force and magnetically attract each other after being energized. In this specific embodiment, each set of vertical plates and cylinders are made of iron. The iron core and the coil wound around it are coaxially arranged with the cylinder. A metal sealing cap is fixedly connected to the front end of the iron core of each set. The outer diameter of the sealing cap is equal to the outer diameter of the cylinder. The sealing cap and cylinder are fixed together by welding. In this embodiment, each set of fixing straps uses Velcro for connection, allowing for quick assembly and disassembly. The tightness can also be adjusted to match different leg diameters, making it widely applicable. Furthermore, to prevent pressure sores on the lamb's legs from the mounting base, a pad is placed between each set of vertical plates and the leg. This pad is made of high-density sponge, and the side of the pad that contacts the vertical plate is fixed with glue. The side of the pad that contacts the leg is curved for better fit and improved comfort. It should be noted that the electromagnetic chucks in this embodiment are installed on the lamb's front legs so that when the two electromagnetic chucks are energized and generate magnetism and attract each other, the two front legs can be fixed together, effectively preventing the lamb from jumping out of the gaps between the fences.In this embodiment, the wireless connection between the receiver and the transmitter 61 is achieved by infrared connection. The infrared transmitting probe of the transmitter 61 protrudes from the outer surface of the mounting housing 31, and the infrared receiving probe of the receiver protrudes from the outer surface of each set of cylinders.

[0022] To make the collar 3 easy to wear around the lamb's neck, the collar 3 includes a strap 32, a quick-connect buckle 33, and a D-ring buckle 34. The strap 32 is threaded onto the connecting ring 311 of the mounting shell 31. The quick-connect buckle 33 includes a male buckle 331 and a female buckle 332, which are respectively connected to the two ends of the strap 32. The D-ring buckle 34 is adjusted to fit the length of the strap 32.

[0023] The method of using the lamb anti-crossing restraint device is as follows: First, the first electromagnetic chuck group 1 and the second electromagnetic chuck group 2 are respectively installed on the lamb's left and right front legs via their fixing straps. The mounting shell 31 of the built-in Hall sensor 5 and transmitter 61 is fixed to the collar 3 and worn on the lamb's neck. At the same time, magnets 4 are installed on the fence bars. When the lamb approaches the fence, the Hall sensor 5 senses the signal of the magnet 4 and triggers the transmitter 61 to send a wireless command. The first coil 13 of the first electromagnetic chuck group 1 will be supplied with a standard polarity current, and the first iron core 12 will generate the N pole. The second coil 23 of the second electromagnetic chuck group 2 will be supplied with a reverse polarity current, and the second iron core 22 will generate the S pole. The first iron core 12 and the second iron core 22 generate a strong magnetic attraction force, instantly attracting and closing the lamb's front legs to restrict its jumping. When the lamb is full and retracts its neck outside the fence, the Hall sensor 5 is beyond the sensing range of the magnet 4 on the fence, and the magnetic force of the two electromagnetic chuck groups is automatically released, restoring its free movement. No manual operation is required throughout the process.

[0024] It should be understood that all the above embodiments are exemplary and not restrictive. Various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this utility model should be within the protection scope of this utility model.
