Description

Technical Field

[0001] The utility model relates to a spraying device for dairy cow breeding, belonging to the technical field of dairy cow breeding. Background Art

[0002] The technology of spraying medicine on dairy cow udders (also known as udder spraying technology) is an important technology in the field of dairy cow breeding, aiming to prevent and control mastitis and other udder health problems. Mastitis is one of the common health problems of dairy cows, resulting in a decrease in milk production, a deterioration in milk quality, and even affecting the overall health of dairy cows. Therefore, spraying medicine on dairy cow udders is a key preventive and therapeutic measure. Spraying medicine on dairy cow udders can be carried out by workers holding a spray head, or by mechanical spraying. Through a feeding mechanism, a support rod equipped with a spray head is sent forward under the udder of a dairy cow to spray medicine upward. After spraying, the support rod is withdrawn backward and moved to the spraying station of the next dairy cow. During mechanical spraying, since dairy cows may move their bodies, the cow legs may occasionally touch the support rod. If the support rod is rigidly connected to the mounting seat, it is very easy to cause equipment damage. Therefore, it is necessary to design a new type of spraying device so that the support rod has a certain degree of flexibility. When the leg of a dairy cow touches the support rod, the support rod can rotate to adjust its posture and can automatically reset. Summary of the Utility Model

[0016] 1. By providing a relatively rotatable first disk body and a second disk body, the mounting seat has a rotation and reset function. The support rod is fixed on the first disk body. When the leg of a dairy cow kicks the support rod during the spraying process, the first disk body can rotate relative to the second disk body. During the rotation of the first disk body, the lever fixed to the first disk body can push the steel ball in the groove. The steel balls transmit power in sequence and move, and finally the force can be transmitted to the elastic body, causing the elastic body to deform and store energy under pressure. The energy stored in the elastic body can drive the steel ball to move back to its original position, thereby pushing the lever in the reverse direction and driving the first disk body to rotate back to its original position. Therefore, compared with the rigid connection method in the prior art, it has a certain degree of rotational freedom, avoiding accidental damage to the equipment due to external forces;

[0017] 2. By providing a spring positioning pin that cooperates with the positioning groove on the first disk body, when the support rod is in the aligned position, the pin body of the spring positioning pin is located in the positioning groove for alignment and positioning; when the first disk body rotates, the pin body of the positioning pin moves out of the positioning groove, and after resetting, the pin body returns to the positioning groove again and provides a force feedback after alignment;

[0018] 3. A fixed disk is provided below the second disk body. The fixed disk is fixed to the feeding mechanism of the spraying device to provide a mounting base for the mounting seat. The second disk body is connected to the fixed disk by bolts; through the above-mentioned cooperation structure of the first disk body and the second disk body, a certain degree of rotational freedom can be provided for the support rod on the horizontal plane, and through the cooperation structure of the second disk body and the fixed disk, when the support rod is pressed down or lifted, the four screw rods can twist correspondingly in the four long holes, so that the second disk body swings relative to the fixed disk, providing a certain degree of swing freedom for the support rod on the vertical plane.
