[0024] The electric milking device and method of the present invention will be described in more detail below in conjunction with the schematic diagram, wherein the preferred embodiments of the present invention are shown. It should be understood that the present invention described herein can be modified by a person skilled in the art while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as being broadly known to a person skilled in the art and not as a limitation of the present invention.

[0025] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are in very simplified form and in non-precise proportions, and are only used to facilitate and clearly assist in illustrating the purpose of the embodiments of the present invention.

[0026] like Figure 1-4 As shown, an embodiment of the present invention proposes an electric milking device, comprising a mounting frame 1 and a first milking mechanism 2, a second milking mechanism 3 installed on the mounting frame 1, and a driving mechanism 16 for driving the first milking mechanism 2 to move, the first milking mechanism 2 comprises two milking claws 5 which are rotatably installed on both sides of the upper end of the mounting frame 1 through a rotating shaft 4, a milking baffle 6 is fixedly installed on one end of the two milking claws 5 close to the rotating shaft 4, and a pressing plate 7 is provided on the inner side of one end of the two milking claws 5 away from the rotating shaft 4, and a tension spring 8 is connected between the two milking baffles 6.

[0027] The driving mechanism 16 includes a driving motor 9 fixedly mounted on the mounting frame 1 , a transmission shaft 10 fixedly mounted on the output shaft end of the driving motor 9 , a first cam 11 fixedly mounted on the transmission shaft 10 , and the first cam 11 abuts against the inner wall of the milking baffle 6 .

[0028] In this embodiment, the second milking mechanism 3 includes a positioning claw 12 rotatably mounted on the rotating shaft 4 at a position directly below the milking claw 5. There are two positioning claws 12, and the two positioning claws 12 are rotatably mounted on the two rotating shafts 4 respectively. A positioning baffle 13 is fixedly mounted on one end of the two positioning claws 12 close to the rotating shaft 4, and a positioning plate 14 is provided on the inner side of one end of the two positioning claws 12 away from the rotating shaft 4. The two positioning baffles 13 jointly abut against a second cam 15, and the second cam 15 is fixedly mounted on the transmission shaft 10.

[0029] In this embodiment, reference Figure 3 The first cam 11 includes a pair of parallel sides and a pair of arc sides, one of the parallel sides and one of the arc sides are connected in sequence, the second cam 15 is elliptical, and the long axis direction of the second cam 15 is inconsistent with the direction of the parallel sides of the first cam 11; for example, the angle α can be between 15° and 45°, and other angles can be set according to actual needs.

[0030] Specifically, by starting the driving motor 9, the transmission shaft 10 is driven to rotate, so that the first cam 11 and the second cam 15 also start to rotate. The specific shape design of the first cam 11 and the second cam 15 and the specific installation method of each other can realize that during the milking process, the two positioning plates 14 and the two pressing plates 7 clamp the cow's nipples in turn to simulate the action of hand milking and reduce damage to the cow's nipples. At the same time, the two positioning plates 14 clamp and position the lower end of the cow's nipples to avoid shaking of the cow's nipples during milking, thereby facilitating the collection of the taken emulsion.

[0031] In this embodiment, the inner end surfaces of the positioning plate 14 and the pressing plate 7 are both arranged in arc shape, and the positioning plate 14 and the pressing plate 7 are both made of silicone material.

[0032] Specifically, the curved surface design fits the round cross-section of the cow's nipple and will not damage the nipple, but the stimulation is more thorough and sufficient. The silicone material further reduces damage and stress and improves the efficiency of milking and milk testing.

[0033] In this embodiment, the pressing plate 7 and the positioning plate 14 are detachably mounted on the milking claw 5 and the positioning claw 12 respectively by fixing screws.

[0034] Specifically, the pressing plate 7 and the positioning plate 14 are detachably mounted on the milking claw 5 and the positioning claw 12 respectively by fixing screws, so that the operator can conveniently replace, clean and disinfect the pressing plate 7 and the positioning plate 14 .

[0035] The following lists the preferred embodiments of the electric milking device to clearly illustrate the content of the present invention. It should be clear that the content of the present invention is not limited to the following embodiments, and other improvements through conventional technical means of ordinary technicians in this field are also within the scope of the present invention.

[0036] like Figure 5 As shown, the embodiment of the present invention provides an electric milking method, comprising the following steps:

[0037] S100, positioning and placing the device: moving the device so that the cow's nipple is located between the two pressing plates 7 and the two positioning plates 14, and ensuring that the pressing plate 7 is located at a corresponding height position of the cow's nipple sphincter.

[0038] Specifically, Figure 3 As shown, the first cam 11 is composed of a pair of parallel edges and a pair of arc edges, and the second cam 15 adopts the design of an elliptical cam. Before positioning and installing the device, the drive motor 9 is started so that the parallel edge of the first cam 11 contacts the milking baffle 6, and the drive motor 9 is turned off. At this time, the two milking claws 5 and the two positioning claws 12 are in an open state, and then the device can be positioned and placed.

[0039] S200, automatic collection of milk samples: starting the driving motor 9 to drive the first cam 11 and the second cam 15 on the transmission shaft 10 to rotate, thereby completing the automatic collection of milk samples.

[0040] Specifically, after the device is positioned and placed, the driving motor 9 is started, and the first cam 11 and the second cam 15 are driven to rotate through the transmission shaft 10. When the long sides of the first cam 11 and the second cam 15 contact the milking baffle 6 and the positioning baffle 13 respectively, the opposite milking claws 5 and the opposite positioning claws 12 will move closer, the pressing plate 7 squeezes the cow's nipples, and the positioning plate 14 positions and clamps the cow's nipples. When the first cam 11 and the second cam 15 rotate from the long side to the short side, the tension spring 8 will gradually pull the close ones apart. When the milking claw 5 rotates from the short side to the long side again, it starts to squeeze the cow's nipple, and repeats this process to achieve automatic collection of milk samples. Due to the specific shape design of the first cam 11 and the second cam 15 and their specific installation methods, during the milking process, when the positioning claw 12 and the milking claw 5 approach the cow's nipple, the positioning plate 14 will contact the cow's nipple first, and then the positioning plate 14 will contact the cow's nipple. The one-after-the-other operation simulates the action of hand milking and reduces damage to the cow's nipple.

[0041] S300, cleaning and disinfection of the device: After the milk sample of a cow is collected, the pressing plate 7 and the positioning plate 14 are rinsed with clean water and disinfectant water to complete the cleaning and disinfection of the device.

[0042] Specifically, the pressing plate 7 and the positioning plate 14 on the milking claw 5 and the positioning claw 12 are disassembled by rotating the fixing screws of the milking claw 5 and the positioning claw 12, and the pressing plate 7 and the positioning plate 14 that have been cleaned and disinfected are replaced. The milk sample is taken from the next cow, and the disassembled pressing plate 7 and the positioning plate 14 are rinsed with clean water and disinfectant water to prepare for replacement and use next time.

[0043] In summary, the present invention has the following advantages over the prior art:

[0044] (1) The device provided by the present invention is easy to operate and can be quickly mastered by inexperienced personnel. It can efficiently simulate the operation process of manual milking, reduce the labor intensity of operators, and detect cow breast diseases more quickly and conveniently, thereby indirectly improving the economic efficiency of the ranch.

[0045] (2) The present invention performs necessary cleaning and disinfection on the milking baffle and the positioning baffle in the device after the milk sample is collected, thereby effectively avoiding the risk of cross-infection due to bacteria between different cows and avoiding the mixing of milk samples from different cows that affects the test results.

[0046] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
