The working principle of the full-automatic medicine applying and milking device for the nipples of the cows provided by the embodiment of the invention is as follows:

when in use, the collecting box 19 is taken down, the medicinal bath liquid is injected into the material pushing plate groove 28, the device is moved to the lower part of the breast of the cow, the nipple of the cow is positioned in the through hole 16, then the double-shaft motor 44 is started, taking the right side as an example, the double-shaft motor 44 drives the connecting shaft 45 to rotate, the connecting shaft 45 drives the fan blades 46 to rotate, the fan blades 46 rotate to blow air to push the material pushing plate 47 to move rightwards, the output end on the right side of the double-shaft motor 44 drives the short bevel gear 48 to rotate so as to drive the wide bevel gear 40 and the gear 39 to rotate, the gear 39 rotates to do circular motion in the circular groove 12, the circular groove 12 drives the long slide block 14 to slide in the long slide block groove 15, the long slide block 14 drives the short slide block 60 to slide in the short slide block groove 41 through the square fixing block 42, the square fixing block 42, the pushing plate 47 moves leftwards to push the medical bath liquid in the pushing plate groove 28 to move so as to drive the semicircular block 23 to rotate upwards by taking the rotating shaft 24 as a rotating center, meanwhile, the torsion spring 25 stores force, the semicircular block 23 drives the wiping plate support rod 22 to rotate upwards, the rotating shaft 24 pushes the medical bath liquid to be sprayed out from the pressure relief valve groove 57 to be sprayed on nipples of cows for sterilization, the wiping plate support rod 22 rotates to drive the fixed block 20 to rotate upwards by taking the rotating shaft 24 as the rotating center, the fixed block 20 drives the wiping plate 21 to rotate upwards, when the rotating shaft rotates to a maximum angle, the upper block 34 moves downwards by gravity to compress the limit slider spring 37, because the initial state of the telescopic rod 31 is shortest, the upper block 34 cannot compress the telescopic rod 31 by the limit slider 38 and the connecting block 35 when moving downwards, so as to be matched with the inclined surface on the limit slider 38 to push the limit slider 38 to the groove bottom of the connecting block groove, the limiting slide block 38 slides out of the connecting block groove 36 by the elastic force of the limiting slide block spring 37, at this time, the limiting slide block 38 is positioned at one side of the upper slide block 34 close to the through hole 16, the telescopic rod 31 is stretched, at this time, the spring telescopic rod 31 pushes the connecting block 35 leftwards to drive the wiping plate 21 to slide leftwards, when the spraying of the medical liquid is finished, the double-shaft motor 44 is reversed, at this time, the material pushing plate 47 moves rightwards to abut against the left end of the connecting shaft 45, at this time, the medical liquid in the material pushing plate groove 28 does not flow, the semicircular block 23 loses the thrust of the medical liquid to the semicircular block, at this time, the wiping plate support rod 22 rotates downwards by the torsion force accumulated by the torsion spring 25 until the semicircular block 23 abuts against the lower side wall of the material pushing plate groove 28, at this time, because the wiping plate 21 has slid a distance leftwards, at this time, the, and then the wiping plate 21 is driven by the wiping plate supporting rod 22 and the fixing block 20 to rotate by taking the nipple of the cow as a rotation center, so that the nipple of the cow is wiped, and the medicinal bath liquid is wiped off. When the motor 56 is started while the dual-shaft motor 44 is started, the output end of the motor 56 drives the shaft 49 to rotate, the shaft 49 drives the milking mass 54 to rotate around the shaft 49 through the rod 50 and the milking shaft 55, because the milking shaft 55 is positioned at the upper part of the milking mass 54, the lower part of the milking mass 54 is in a vertical state under the action of gravity, seven rollers can simultaneously abut against the nipples of the cows when the shaft 49 continues to rotate, the shafts 49 continue to rotate to drive the rollers at the left side and the right side to approach each other to squeeze the nipples, the rollers at the left side and the right side are driven to roll on the nipples and move downwards to squeeze the milk when the shaft 49 continues to move, the action replaces the manual milking action and perfectly simulates the manual milking action, the collecting box 19 is placed into the collecting box chute 18 after the cows are confirmed to be sick by squeezing a few milks, the collecting box 19 is removed when the milking is finished, for example on the right side, the right wiping plate 21 is pushed to move rightwards, the wiping plate 21 drives the limit sliding block 38 to move rightwards through the connecting block 35, so that the limit sliding block 38 is matched with the inclined plane on the upper sliding block 34 to move downwards to compress the limit sliding block spring 37, and meanwhile, the upper sliding block 34 moves leftwards under the elastic force of the upper spring 33 to enable the limit sliding block 38 to be positioned in the groove of the upper sliding block 34 again.

The above embodiments are only preferred embodiments of the present invention, and are not intended to limit the technical solutions of the present invention, so long as the technical solutions can be realized on the basis of the above embodiments without creative efforts, which should be regarded as falling within the protection scope of the patent of the present invention.
