Technical Field

[0001] This utility model relates to the field of livestock detection and identification technology, specifically a livestock quantity and body length identification system based on visual detection. Background Technology

[0002] The investigation of dead pigs is an important part of pig farming, insurance claims and animal disease prevention and control. It aims to determine the cause of death, assess the loss and take targeted prevention and control measures through scientific investigation.

[0003] The existing technology (Chinese patent publication number CN119169693A, publication date 2024-12-20) is a livestock monitoring system based on visual images, belonging to the technical field of livestock monitoring systems. It includes collecting data on livestock behavior-induced states, acquiring data such as livestock movements and water splashes, marking the position of livestock, the direction of water splashes, and the position of objects in the livestock behavior-induced state data, and cleaning the livestock behavior-induced state data. When the device is working, the livestock behavior-induced state model will infer the image acquired from the camera in real time, determine the position, direction, or force of livestock, water splashes, or objects, and protect the monitoring head accordingly. Through the setting of the livestock behavior-induced state model, during the livestock monitoring process, it can acquire livestock behavior data or, if objects or water droplets may damage or come into contact with the monitoring head, reposition it or provide protection to prevent livestock from damaging it, thus extending its service life.

[0004] While existing technologies can detect livestock, their visual inspection equipment has a limited detection angle during operation, making it impossible to perform multi-angle visual inspection of livestock. Furthermore, there are blind spots in the detection when the livestock are moving within a fixed detection angle, which has certain limitations.

[0005] Therefore, we propose a visual detection-based livestock quantity and body length recognition system to address the aforementioned problems. Utility Model Content

[0006] The purpose of this invention is to provide a visual detection-based livestock quantity and body length identification system to solve the problems mentioned in the background art, such as the limited detection angle of visual detection equipment during operation, the inability to perform multi-angle visual detection of livestock, and the existence of blind spots in the detection when the detection is at a fixed angle, which have certain limitations.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a livestock quantity and body length identification system based on visual detection, comprising a fixed bracket, a connecting plate fixedly connected to the lower end of the fixed bracket, and a sliding groove provided inside the connecting plate, with a movable frame slidably connected inside the sliding groove. An adjustment box is rotatably connected to the lower surface of the movable frame, and an image recognition device for visual detection of livestock is provided on the lower side of the adjustment box. An adjustment mechanism is provided inside the adjustment box, which adjusts the recognition angle of the image recognition device by rotating a rotating ball contained therein. At the same time, a dust removal mechanism is also provided inside the adjustment box, which cleans the image recognition device synchronously with the operation of the adjustment mechanism.

[0008] Furthermore, a threaded rod is rotatably connected above the connecting plate, and a first motor is fixedly connected above the connecting plate, with the output end of the first motor fixedly connected to the outer end of the threaded rod.

[0009] Furthermore, the outer side of the threaded rod is threaded with a threaded block, and the lower surface of the threaded block is fixedly connected to the upper surface of the movable frame. The movable frame forms a sliding structure with the sliding groove through the threaded block.

[0010] Furthermore, the adjustment mechanism includes a second motor, which is fixedly connected to the side of the movable frame, and the output end of the second motor is rotatably connected to the movable frame.

[0011] Furthermore, a gear is fixedly connected to the output shaft of the second motor, and a gear ring is fixedly connected to the outside of the adjustment box, with the gear ring and the gear meshing with each other.

[0012] Furthermore, a telescopic rod is fixedly connected inside the adjustment box, and a rotating rod is hinged to the output end of the telescopic rod. A rotating ball is nested inside the lower side of the adjustment box, and the rotating ball is fixedly connected to the image recognition device. The upper side of the rotating ball is hinged to the other end of the rotating rod.

[0013] Furthermore, the dust removal mechanism includes a nozzle, a pressure plate is fixedly connected to the outer side of the rotating ball, and an air bladder is fixedly connected between the lower surface of the pressure plate and the interior of the adjustment box, and a nozzle for cleaning the image recognition device is provided through the lower side of the air bladder.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. A threaded rod is provided. When the first motor is started, the threaded rod is rotated, which causes the threaded block to move laterally and simultaneously moves the adjustment box to adjust its position. This allows for better adjustment of the image recognition device's position, thereby better acquiring livestock species and quantity data and providing a favorable basis for subsequent intelligent reporting.

[0016] 2. A telescopic rod is provided. When the telescopic rod is activated, it synchronously causes the rotating rod to rotate. The rotated rod then synchronously pushes the rotating ball hinged at its lower end to rotate as well. This causes the rotating ball to drive the image recognition device to deflect synchronously, thereby enabling visual detection operations at different angles, further identifying the species and number of livestock, and reducing recognition errors.

[0017] 3. When the rotating ball deflects under the action of the rotating rod, the pressure plate deflects synchronously. At this time, the pressure plate can squeeze the air bladder set below it. After being squeezed, the air bladder can discharge the gas stored inside through the nozzle. The discharged gas can be sprayed towards the image recognition instrument and remove the dust attached to the image recognition instrument, reducing the interference of dust on visual detection.

[0018] 4. Start the second motor, which drives the gear to rotate. The rotating gear drives the meshing gear ring to rotate synchronously. At this time, the gear ring drives the adjustment box to rotate, which in turn drives the image recognition device to rotate synchronously. The rotation of the adjustment box and the rotation of the rotating ball work together to further improve the detection range of the image recognition device and reduce detection errors.

The lower end of the fixed bracket 1 is fixedly connected to a connecting plate 2, and the interior of the connecting plate 2 is provided with a sliding groove 3. The interior of the sliding groove 3 is slidably connected to a movable frame 6. The lower surface of the movable frame 6 is rotatably connected to an adjustment box 7, and the lower side of the adjustment box 7 is provided with an image recognition instrument 8 for visual detection of livestock species.

The movable frame 6 forms a sliding structure with the sliding groove 3 through the threaded block 5.

[0028] A threaded rod 4 is installed. When the first motor 9 is started, the threaded rod 4 is rotated by the first motor 9. At this time, the threaded block 5 can synchronously drive the moving frame 6 to move laterally under the threaded action of the threaded rod 4.

[0029] Example 2: Figure 3 , Figure 4 and Figure 6The technical solution shown is provided by the present invention as follows: A livestock quantity and body length recognition system based on visual detection discloses an adjustment mechanism, which realizes the adjustment of the recognition angle of the image recognition instrument 8: The adjustment mechanism is provided inside the adjustment box 7. The adjustment mechanism realizes the adjustment of the recognition angle of the image recognition instrument 8 by rotating the rotating ball 13 contained therein. The adjustment mechanism includes a second motor 10, which is fixedly connected to the side of the moving frame 6. The output end of the second motor 10 is rotatably connected to the moving frame 6. A gear 12 is fixedly connected to the output shaft of the second motor 10.

The upper side of the rotating ball 13 is hinged to the other end of the rotating rod 15.

[0030] When the telescopic rod 14 is activated, it synchronously causes the rotating rod 15 to rotate. The rotated rod 15 then synchronously pushes the rotating ball 13, which is hinged at its lower end, to rotate synchronously. This causes the rotating ball 13 to drive the image recognition device 8 to deflect synchronously, thereby enabling visual detection operations at different angles. This further identifies the species and number of livestock and reduces recognition errors. The second motor 10 is then activated, which drives the gear 12 to rotate.

An air bag 17 is fixedly connected between the lower surface of the pressure plate 16 and the inside of the adjustment box 7. The nozzle 18 for cleaning the image recognition instrument 8 is provided through the lower side of the air bag 17.

[0032] When the rotating ball 13 deflects under the action of the rotating rod 15, it can simultaneously drive the pressure plate 16 to deflect.
