DETAILED DESCRIPTION

[0034] The technical solutions of the present application will be further described in detail below in combination with specific embodiments.

[0035] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0036] Embodiment 1:

[0037] A rotary disc type milking device for intelligently controlling the entry and exit of cows, such as Figures 1 to 10As shown, the system includes a base 1 and a control unit for controlling the entry and exit of cows. The control unit includes a limiting ring 4 and a support plate 8. The limiting ring 4 is rotatably connected to the top outer wall of the base 1, and the support plate 8 is fixed to the circumferential outer wall of the limiting ring 4 by bolts. A housing frame 16 is fixed to the top of the support plate 8 by bolts, and a top plate 17 is fixed to the top of the housing frame 16 by bolts. A negative pressure assembly is installed on the top of the top plate 17. A milking mechanism is installed at the output end of the negative pressure assembly, and a rigid pipe 25 is installed at the input end of the negative pressure assembly. A sliding plate 2 is fixed to the top outer wall of the base 1 by bolts. 36, and the top of the slide plate 36 is fixed with an air cylinder 40, and the inner wall of the air cylinder 40 is slidably connected with a piston plate 28. The outer wall of the air cylinder 40 is equipped with a pressure relief valve, and one end of the air cylinder 40 is fixed with a connector assembly that works with a rigid pipe 25. One end of the piston plate 28 is welded with a pressing rod 29, and one end of the pressing rod is fixed with a driving assembly. The driving assembly includes a drive arm 35 welded to one end of the pressing rod 29, and a rotating shaft 39 is movably connected to the side wall of the drive arm 35. A flexible strip 41 is fixed to the outer circumference of the rotating shaft 39, and an indicator light 38 is installed at one end of the flexible strip 41.

[0038] By mounting the support plate 8 in a ring on the outer circumference of the limiting ring 4, the cow moves onto the support plate 8 during milking and is milked by the milking mechanism. The milking mechanism is fixed to the cow's udder during milking. After the negative pressure component is activated, the negative pressure is used to drive the milking mechanism to perform milking operations. After the cow finishes milking, when the corresponding connector component on one of the support plates 8 moves to connect with one end of the rigid pipe 25, the air output from the negative pressure component is introduced into the air cylinder 40 through the connector component. The air pressure pushes the piston plate 28, causing the squeeze rod 29 to slide along the air cylinder 40 and drive the indicator light 38 to move laterally. A pressure relief valve is installed on the air cylinder 40 to ensure the safety of the negative pressure component during operation. When the indicator light 38 is turned on, it can attract the cow. At the same time, when the flexible strip 41 moves laterally and contacts the cow's head, the cow moves backward under the guidance of the indicator light 38, thus leaving the support plate 8, making it easier for the next cow to get onto the support plate 8 for milking.

[0039] Furthermore, the negative pressure assembly includes a vertical plate 26 and a negative pressure pump 33. The vertical plate 26 is fixed to the top outer wall of the top plate 17 by bolts, and the negative pressure pump 33 is fixed to the outer wall of one side of the vertical plate 26 by bolts, and the rigid pipe 25 is threaded to the output end of the negative pressure pump 33.

[0040] When milking, the negative pressure pump 33 is started to generate negative pressure, which causes the milking assembly to descend under the action of negative pressure and milk to be squeezed out from the cow's teat.

[0041] Further, the milking mechanism comprises a support plate 20 and a pressure sensor 21, the support plate 20 is fixed on the inner wall of the housing frame 16 by bolts, and the pressure sensor 21 is fixed on the top of the support plate 20 by screws, and the top of the pressure sensor 21 is fixed with a storage tank 55 by screws, and the side wall of the storage tank 55 is provided with a negative pressure pipe 27, and one end of the negative pressure pipe 27 is fixed with a connecting pipe 19, and the end of the connecting pipe 19 away from the storage tank 55 is provided with a breast pump 15;

[0042] When the staff inserts the breast pump 15 into the udder of the cow during milking, the breast pump 15 and the udder are adsorbed and fixed under the action of negative pressure, the milk is guided by the breast pump 15 and the connecting pipe 19, and finally moves to the storage tank 55 for storage, the weight of the milk in the storage tank 55 is monitored by the pressure sensor 21, when the weight of the milk reaches the set milking amount, the pressure sensor 21 feeds back the electrical signal to the processing terminal, and the processing terminal controls the negative pressure pump 33 to be closed, at this time, the negative pressure in the breast pump 15 disappears, and the breast pump 15 automatically falls off from the udder of the cow.

[0043] Further, the top outer wall of the base 1 is fixed with a support frame 11 by bolts, and the through hole formed in the surface of the support frame 11 is rotatably connected with a conveying pipe 12, and the top of the conveying pipe 12 is welded with a guide pipe 3, and the end of the guide pipe 3 away from the conveying pipe 12 is fixedly connected with the circumferential inner wall of the limiting ring 4, and the bottom of the storage tank 55 is fixed with a milk discharge pipe 23 through a flange, the bottom of the milk discharge pipe 23 is fixed with an annular pipe 6 through an electromagnetic valve 5, and the annular pipe 6 and the guide pipe 3 are connected through a connecting pipe;

[0044] When the pressure sensor 21 monitors that the weight of the milk in the storage tank 55 reaches the set value, at this time, the processing terminal controls the electromagnetic valve 5 to be opened when receiving the electrical signal, so as to guide the milk in the storage tank 55 into the annular pipe 6 through the electromagnetic valve 5, and finally guide the milk into the conveying pipe 12 through the guide pipe 3 by using the connecting pipe, and guide the milk into the collecting tank for collection by using the conveying pipe 12, when one of the milking mechanisms fails, the electromagnetic valve 5 is closed to facilitate the maintenance of the milking mechanism.

[0045] Further, the top outer wall of the base 1 is fixed with a mounting frame 9 by bolts, and the top inner wall of the mounting frame 9 is fixed with a driving motor 10 by bolts, and the output end of the driving motor 10 and the circumferential outer wall of the conveying pipe 12 are driven by a synchronous belt;

[0046] The driving motor 10 can drive the conveying pipe 12 to rotate by the transmission action of the synchronous belt, and the limiting ring 4 is driven to rotate in the process of rotating the conveying pipe 12.

[0047] Further, the joint assembly comprises an extrusion pipe 34, a corrugated expansion pipe 45, a lining plate 46 and a tapered chuck 47, the extrusion pipe 34 is connected to one end of the air cylinder 40 through a flange, the corrugated expansion pipe 45 is fixed to one end of the extrusion pipe 34 by adhesion, and the lining plate 46 is adhered to the other end of the corrugated expansion pipe 45, and the tapered chuck 47 is welded to one side of the outer wall of the lining plate 46;

[0048] When the tapered chuck 47 gradually approaches one end of the hard pipe 25, the tapered chuck 47 is finally connected to the hard pipe 25 due to the tapered end of the tapered chuck 47 and the elasticity of the corrugated expansion pipe 45, and the negative pressure pump 33 generates negative pressure after being started again when the breast pump 15 falls off the cow's breast, so that air is introduced into the extrusion pipe 34 through the negative pressure pump 33 and the hard pipe 25, and then the air inflates into the air cylinder 40 through the extrusion pipe 34, thereby realizing the lateral movement of the indicator light 38.

[0049] Further, one end of the extrusion pipe 34 is fixed with a shielding shell 52, the circumferential inner wall of the shielding shell 52 is slidably connected with a guide rod 48, the corrugated expansion pipe 45 and the lining plate 46 are fixedly connected, the other end of the guide rod 48 is fixedly connected with the lining plate 46, one end of the guide rod 48 is fixed with an electromagnet 49 through a screw, one side of the inner wall of the shielding shell 52 is fixed with a permanent magnet 51 through a screw, and the adjusting spring 50 is clamped between one side of the outer wall of the permanent magnet 51 and one side of the outer wall of the electromagnet 49;

[0050] The relative movement path between the tapered chuck 47 and the extrusion pipe 34 can be guided by arranging the corrugated expansion pipe 45 and the shielding shell 52, thereby avoiding the bending of the tapered chuck 47 relative to the extrusion pipe 34, when the tapered chuck 47 and the hard pipe 25 are clamped, the adjusting spring 50 can be used to support the tapered chuck 47 and the hard pipe 25 to ensure the relative stability between them, and when the electromagnet 49 is electrified, the magnetic poles of the electromagnet 49 and the permanent magnet 51 repel each other, which further ensures the relative stability between the tapered chuck 47 and one end of the hard pipe 25, and avoids the separation between them during the air inlet process.

[0051] Further, the outer wall of the top of the base 1 is fixed with a sliding plate one 14 through a bolt, and the top of the sliding plate one 14 is fixed with a rack 13 through a bolt, and one end of the rotating shaft 39 is connected with a gear 42 engaged with the rack 13 through a key;

[0052] The gear 42 and the rack 13 are arranged to enable the indicator light 38 to rotate during lateral movement, and the indicator light 38 and the flexible strip 41 rotate during rotation to rotate and move the head of the cow, thereby improving the guiding effect on the cow.

[0053] Further, the sliding groove is arranged on the side wall of the rack 13 and is slidably connected with a sliding block 24, the rotating shaft 39 is rotatably connected with the sliding block 24, the through hole is arranged on the surface of the sliding block 24 and is embedded with a spraying disc 44, and the outer wall of one side of the spraying disc 44 is threadedly connected with a spray head 43;

[0054] The spray head 43 and the spraying disc 44 are arranged to clean and flush the support plate 8 when the sliding block 24 moves transversely, the spray head 43 can clean the shell of the indicator lamp 38 when spraying, and the flexible strip 41 can move the water sprayed by the spray head 43 when rotating, so that the spraying range of the spray head 43 is improved.

[0055] Further, the through hole is arranged on the surface of the lining plate 46 and is embedded with a proximity switch 53, the outer wall of the hard pipeline 25 is welded with a square plate 54, and the square plate 54 is threadedly connected with an induction plate 22 which is used in cooperation with the proximity switch 53;

[0056] When the induction plate 22 rotates with the limiting ring 4, the magnetic poles of the electromagnet 49 and the permanent magnet 51 are opposite, so that the adjusting spring 50 is compressed, when the proximity switch 53 moves to the induction plate 22, the proximity switch 53 feeds back a signal to the processing terminal at this time, the processing terminal controls the driving motor 10 to stop driving the limiting ring 4 and the support plate 8 to rotate, at this time, the pressure sensor 21 feeds back the monitored pressure value to the processing terminal, if the amount of milk in the storage tank 55 reaches the set amount at this time, the processing terminal controls the electromagnet 49 to change the magnetic pole so that the joint assembly and the hard pipeline 25 are attracted and fixed, if the amount of milk in the storage tank 55 does not reach the set amount, the processing terminal controls the driving motor 10 to make the driving motor 10 continue to drive the limiting ring 4 and the support plate 8 to rotate.

[0057] Further, the outer wall of the top of the support plate 8 is fixed with a isolation fence 18 through bolts, and the outer wall of the top of the base 1 is fixed with a fence 2 through bolts;

[0058] The isolation fence 18 is arranged to separate multiple support plates 8, and the fence 2 is arranged to protect the cows when the limiting ring 4 and the support plate 8 rotate.

[0059] Further, the top of the base 1 is placed with a ramp 7;

[0060] The ramp 7 is arranged to guide the cows to go up and down.

[0061] In this embodiment, when milking a cow is required, the drive motor 10 first drives the limit ring 4 and the support plate 8 to rotate. When one of the support plates 8 rotates to a position directly opposite the ramp 7, the ramp 7 and the indicator light 38 guide the cow to move onto the support plate 8 via the ramp 7. Then, the operator inserts the milk suction head 15 into the cow's udder. The negative pressure assembly fixes the milk suction head 15 to the cow's udder. The negative pressure assembly draws milk into the storage tank 55 for storage. The pressure sensor 21 monitors the weight of the milk in the storage tank 55. When the milk collection reaches the set weight, the pressure sensor 21 sends an electrical signal back to the processing terminal. The processing terminal then controls the negative pressure assembly to close, completing the milking of the cow.

[0062] Example 2:

[0063] A type of intelligent rotary milking equipment for controlling the entry and exit of cows, such as Figures 1 to 10 As shown, in order to support the cows, this embodiment makes the following additions based on embodiment 1: the inner walls of the grooves opened on the side walls of the second slide plate 36 and the grooves opened on the side walls of the first slide plate 14 are slidably connected to the same limiting rail 37, and the inner wall of the bottom of the second slide plate 36 is fixed with a telescopic cylinder 32 by bolts, and the inner wall of the telescopic cylinder 32 is slidably connected with a telescopic rod 31, and the top of the telescopic rod 31 is fixedly connected to the bottom of the limiting rail 37. The bottom of the telescopic cylinder 32 and one end of the air cylinder 40 are fixed with the same air pipe 30.

[0064] As the piston plate 28 slides along the inner wall of the air cylinder 40, it pushes the gas medium inside the chamber of the air cylinder 40. The gas medium is introduced into the bottom of the telescopic cylinder 32 through the air pipe 30. The gas medium is used to lift the telescopic rod 31, so that the limiting bar 37 can slide up along the sliding plate 14 and the sliding plate 2 36. This allows the limiting bar 37 to release its protection on the cow when it needs to leave the support plate 8. When the cow that has finished milking leaves, and other cows that need to be milked move to the support plate 8, when the joint assembly and the rigid pipe 25 disengage, the limiting bar 37 moves down along the sliding plate 14 and the limiting bar 37 under its own weight. A certain amount of damping is set between the limiting bar 37 and the sliding plate 14, and the groove opened on the side wall of the limiting bar 37, so as to slow down the falling rate of the limiting bar 37 and prevent the limiting bar 37 from falling too fast. At the same time, the squeezing rod 29 is reset relative to the air cylinder 40 by the conduction effect of the air pipe 30.

[0065] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
