[0029] Please refer to Figure 1-Figure 5 The utility model provides an automatic body size and weight measuring device for sheep, comprising a limiting gate 1, a reader 2, a weighing device 3, a body size measuring component 4 and a fence 5. The weighing device 3 is a floor scale. The measuring device can be set at the entrance or exit of the sheepfold. The body size measuring component 4 includes three 3D point cloud cameras 41. The limiting gate 1 and the weighing device 3 are arranged side by side. The fence 5 is arranged on both sides of the weighing device 3. The reader 2 is fixedly arranged on the fence 5. A plurality of the 3D point cloud cameras 41 are arranged on the weighing device 3. The sheep can only enter the restricted gate 1 one by one through the weighing device 3 and the left side, right side and top of the fence 5. The sheep then passes through the reader 2 along the fence 5. The reader 2 reads the electronic ear tag of the sheep, and then walks to the weighing device 3 and under the body measurement component 4. The weighing device 3 reads the current weight of the sheep. The three 3D point cloud cameras 41 use laser projection and triangulation principles to obtain the current indicators such as the abdominal circumference, waist circumference and body width of the sheep. During the measurement process, there is no need to ensure that the sheep are motionless, and there is no need for manual transportation and manual driving of the sheep.

[0030] Specifically, refer to Figure 2 The limiting door 1 includes an outer frame 11 and a movable baffle 12. A connecting fulcrum 13 is provided between the outer frame 11 and the movable baffle 12. The movable baffle 12 swings back and forth through the connecting fulcrum 13. The movable baffle 12 is wavy and includes a first peak point 121 and a second peak point 122. The first peak point 121 is lower than the second peak point 122. Figure 3 The first peak point 121 and the second peak point 122 are both high peak points. When the sheep touches the first peak point 121, the second peak point 122 blocks the sheep. As the sheep continues to move forward, the sheep touches the second peak point 122. With the assistance of the connecting fulcrum 13, the first peak point 121 blocks the entrance of the outer frame 11. When the first sheep completely leaves the limiting gate 1, the first peak point 121 is reset, so that the second sheep can enter the limiting gate 1. Therefore, only one sheep can pass through at a time, and the body size and weight of the sheep are measured at intervals.

[0031] Furthermore, the movable baffle 12 is provided with a pushing handle 123 , which is arranged on one side of the first sealing mold. When the movable baffle 12 cannot be reset, the movable baffle 12 can be pushed around the connecting fulcrum 13 with the help of the pushing handle 123 .

[0032] Furthermore, the body size measurement component 4 also includes a gantry 42, and the 3D point cloud camera 41 is fixed on the gantry 42. The 3D point cloud camera 41 is placed at a higher position than the fence 5. The 3D point cloud camera 41 uses a laser arranged therein to emit a light beam, which is projected onto the surface of the sheep body; after the light is reflected by the surface, the position of the reflected light is captured by the camera, and the three-dimensional coordinates of each point on the surface of the sheep are calculated according to the angle and position of the light using the triangulation principle.

[0033] Furthermore, a computer cabinet 43 is provided on the gantry 42, and the computer cabinet 43 is connected to the reader 2, the weighing device 3 and the 3D point cloud camera 41. The computer cabinet 43 has a corresponding control system and sheep growth and development tracking and analysis software, which synthesizes the three-dimensional coordinates of multiple surface points collected by the 3D point cloud camera 41 into a complete sheep body surface model, calculates abdominal circumference, waist circumference, body width, abdominal width and other indicators through point cloud data, and the control system matches and records the electronic ear tag of the sheep read by the reader 2 with the body size and weight data. The sheep growth and development tracking and analysis software automatically stores the above data, realizes the full-cycle recording and tracking of the growth and development data of each sheep from the beginning of breeding to the market, and automatically analyzes the current growth and development status of each sheep, providing a scientific basis for the next step of adjusting and optimizing the sheep feeding plan, and realizing refined feeding.

[0034] Furthermore, the width between the fences 5 is smaller than the width of the weighing device 3 to prevent the sheep from stepping out of the weighing device 3 .

[0035] Furthermore, the gantry 42 includes a hollow tube 421 and a base 422 , and the hollow tube 421 is fixed on the base 422 . The design of the hollow tube 421 facilitates wiring and hides the power cord of the 3D point cloud camera 41 .

[0036] The above-mentioned embodiment only expresses one implementation method of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
