2. In the present invention, through the setting of a heavy protection mechanism, after the loading table rises to the preset height of the belly, the user can realize the fine adjustment of the position of the toggle top rod by holding the bottom sleeve and turning it upwards. The engagement of the ratchet rod avoids the falling of the bottom sleeve through the self-locking effect, and the toggle top rod bears against the joint of the corbel to restrain the range of motion of the corbel to prevent the yak from kicking and hurting people in a frightened state. After that, the second air cylinder is activated. , the top sleeve slides on the top of the ratchet rod, so that the ratchet rod is located on the top of the rotating pin and rotates counterclockwise until the toggle top rod bears against the corbel joint. In addition, the top sleeve drives the top end plate of the ratchet rod to rotate counterclockwise synchronously through the top sleeve spring. Under the action of the support rod, the subsequent bolting of the left splint of the end plate to the thigh of the cow is realized, so that the yak is always under the restraint to avoid injury incidents.

3. In the present invention, through the setting of the double protection mechanism, during the rotation and locking process of the end plate, the swing rod at the open end of the splint contacts the tendon of the thigh, and the swing rod overcomes the elastic force of the torsion spring and rotates counterclockwise, so that the bottom locking point is released from the anti-fall. Hook groove, after the thigh is completely placed in the inner cavity of the splint, the swing rod is returned to the anti-drop hook slot again under the elastic restoring force of the torsion spring. Once it is placed in the accommodating cavity, it cannot break free under the restraint of the splint. With the setting of the toggle ejector, the scientific mechanical structure ensures the maximum restraint of the corbel and avoids the occurrence of injuries caused by the corbel.

4. The present invention activates the third cylinder through the setting of the triple protection mechanism, drives the synchronizing rod to rotate in the shaft sleeve on the left side of the frame through the driven crank, synchronously drives the guard plate set in the middle of the synchronizing rod to turn over, and sends the subsequent milk picking mechanism to the shaft. When entering the preset milk collection position, the guard plate is set to facilitate the collection of the spilled or splashed milk during the milk collection process, so as to avoid the waste of milk. In addition, it also limits the sideways position of the yak to ensure the milk collection position. of stability.

5. In the present invention, through the setting of the milk picking mechanism, the turntable is activated to make it rotate, and the position of the rollers in the corner groove of the turntable surface changes, so that the jaws slide and close inside the back plate to hold the teat of the yak, and the jaws are multi-segmented. The yak is set in the same structure and is elastically connected to the base through a spring, which reduces the discomfort brought to the yak when the gripper grips the teat, and avoids irritating the yak and causing emotional fluctuations. The back plate is located on the right side of the guard plate. In the masturbation action of milk, first squeeze the base of the nipple, and then squeeze the nipple in sequence to express the milk, so as to ensure the output rate of yak milk.
