The fourth step, through control button operation chest abdominal girth measuring device 2, successively measure the chest girth and the abdominal girth of sheep, concrete operating procedure: the stretching (contracting) button of the pushing cylinder 28 is pressed to enable the draw bar 25 and the U-shaped rod 26 to be located at the belly position of the sheep, then the stretching button of the left and right cylinders I21, the stretching button of the left and right cylinders II 22 and the switch-on button of the electromagnet 252 are pressed to enable the aligning rod 241 to be located at the middle position of the two frame bodies 1, meanwhile, the draw bar 25 sucks the ball 271, then the contracting button of the left and right cylinders I21, the stretching button of the upper and lower cylinders I23 and the stretching button of the left and right cylinders I21 are pressed in sequence to enable the ball 271 to be finally attached to the aligning rod 241, the resetting of the sheep is recorded, then the contracting button of the left and right cylinders I21, the stretching button of the upper and lower cylinders I23 and the stretching button of the left and right cylinders I21 are pressed in sequence to enable the ball 271 to return to the left end of the lower side of the. All the buttons for the above measurement can be replaced by a general circumference measuring button, i.e. the circumference measuring button is pressed down when the drawbar 25 and the U-shaped bar 26 are pushed to the corresponding chest or abdomen position by the push cylinder 28.
In a fifth step, the anchoring device 3 and the thoracoabdominal circumference measuring device 2 are returned to the initial position by means of the control button 51 (which can also be controlled by means of a total control button 51).
And sixthly, pressing down reverse buttons (the vertical rod 42 rotates by 90 degrees, and the baffle rod 43 is parallel to the transverse rod 11) of two driving motors 44 at the front end of the frame body 1 to drive the sheep out of the space between the two frame bodies 1.
It should be noted that although the present specification describes embodiments, not every embodiment includes only a single technical solution, and such description of the specification is only for clarity, and those skilled in the art should take the specification as a whole, and the technical solutions in the embodiments may be appropriately combined to form other embodiments that can be understood by those skilled in the art.
