For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0041] It should also be noted that, in the description of the present application, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment. In the absence of further restrictions, the elements defined by the statement "comprise one..." do not exclude the presence of other identical elements in the process, method, article or equipment including the elements.

[0042] In order to solve the problems existing in the prior art, an embodiment of the present application provides a milk sampler, such as Figure 1-2As shown, it includes a sampling bottle 1; a shunt tube 5 connected to the bottle mouth of the sampling bottle 1 through a connecting cover 2; the connecting cover 2 is configured to adjust the milk flow rate when the shunt tube 5 transports milk into the sampling bottle 1; a stirring component is arranged in the inner cavity of the sampling bottle 1; the stirring component includes a rotating shaft 31 arranged along the extension direction of the sampling bottle 1, a plurality of first rod bodies 32 extending outwardly from the outer side wall of the rotating shaft 31; and a plurality of second rod bodies 33 corresponding to the plurality of first rod bodies 32, the second rod bodies 33 are connected to the end of the first rod body 32 away from the rotating shaft 31; the ends of the plurality of second rod bodies 33 close to the connecting cover 2 and the ends away from the connecting cover 2 are not on the same plane. Specifically, when the lengths of the plurality of second rods 33 are all equal and the center points thereof are all connected to the corresponding first rods 32, the plurality of first rods 32 may be staggered so that the ends of the plurality of second rods 33 close to the connection cover 2 and the ends away from the connection cover 2 are not on the same plane; when the plurality of first rods 32 are arranged around the same circumference, the plurality of second rods 33 of the same length may be staggered so that the ends of the plurality of second rods 33 close to the connection cover 2 and the ends away from the connection cover 2 are not on the same plane.

[0043] In the above-mentioned embodiment of the present application, since the milk entering the sampling bottle 1 is an uninterrupted process, the sampling personnel also need to uninterruptedly transfer the collected milk samples from the sampling bottle 1 to the detection bottle. If the milk in the sampling bottle 1 is not mixed evenly, it will cause errors in the milk detection and inaccurate detection results. Therefore, the setting of the stirring component can make the milk entering the sampling bottle 1 always maintain a uniformly mixed state, reduce the probability of errors in the detection process, and greatly improve the accuracy. Specifically, the setting of the second rod body 33 in the stirring component close to the connecting cover 2 and the end away from the connecting cover 2 are not on the same plane, which can increase the stirring force of the stirring component and make the milk in the sampling bottle 1 more evenly mixed. The connecting cover 2 can control the flow rate of milk entering the sampling bottle 1 according to the milking speed of the cow, so that the amount of front milk, middle milk and back milk produced by the cow entering the sampling bottle 1 is also relatively uniform, further improving the accuracy of milk detection.

[0044] In a specific embodiment, a driving assembly connected to the rotating shaft 31 and used to drive the rotating shaft 31 to rotate is installed at the bottom of the sampling bottle 1. When the driving assembly is turned on, the driving assembly can drive the rotating shaft 31 to rotate, and the rotating shaft 31 drives the first rods 32 and the second rods 33 to rotate, so as to achieve stirring of the milk flowing into the sampling bottle 1.

[0045] Furthermore, the driving assembly includes a driving shaft 41 connected to the rotating shaft 31; the driving shaft 41 extends to the top of the bottom of the sampling bottle 1; a driving motor 42 for driving the driving shaft 41 to rotate; and a power supply (not shown in the figure) for providing electrical energy to the driving motor 42. The driving assembly also includes a power switch; when the power switch is turned on, the power supply can supply power to the driving motor 42, the driving motor 42 rotates, and the driving shaft 41 on the driving motor 42 drives the rotating shaft 31 to rotate, thereby stirring the milk sample in the sampling bottle 1; when the power switch is turned off, the power supply stops supplying power to the driving motor 42, the driving motor 42 stops rotating, and the rotating shaft 31 also stops rotating, and the stirring of the milk sample in the sampling bottle 1 stops. The power supply can be a battery. Of course, the power supply method can also be other methods without affecting the use effect of this application.

[0046] In a specific embodiment, the bottom of the sampling bottle 1 is raised upward around the driving shaft 41 to form an annular protrusion 11; the center of the annular protrusion 11 forms a plug-in slot 12; the rotating shaft 31 is connected to the driving shaft 41 of the driving assembly through the plug-in slot 12. In other words, the driving shaft 41 is located at the bottom of the plug-in slot 12, and the rotating shaft 31 passes through the plug-in slot 12 to connect with the driving shaft 41. The formation of the plug-in slot 12 on the annular protrusion 11 improves the stability of the rotating shaft 31. When the rotating shaft 31 and the driving shaft 41 fail to separate during rotation, the rotating shaft 31 will not be separated from the plug-in slot 12 due to the obstruction of the side wall of the plug-in slot 12, and the sampling bottle 1 will not be damaged.

[0047] In a specific embodiment, a plurality of second rods 33 are evenly arranged around the outer periphery of the protrusion 11. In this way, the plurality of second rods 33 are closer to the bottom of the sampling bottle 1 than the connecting cap 2, so that even if there is less milk sample in the sampling bottle 1, it can still be stirred evenly.

[0048] In a specific embodiment, the connecting cover 2 includes a shell 21 having a accommodating cavity and the two ends of which are respectively connected to the bottle mouth of the sampling bottle 1 and the tube mouth of the shunt tube 5; the shell 21 has a top wall, a bottom wall and a side wall forming the accommodating cavity, and the shell 21 also includes a first joint portion (not shown in the figure) and a second joint portion (not shown in the figure) which are respectively connected and fixed to the bottle body of the sampling bottle 1 and the tube mouth of the shunt tube 5, the first joint portion is formed by the top surface edge of the shell 21 extending outward, or is formed by the top surface edge of the shell 21 being recessed inward, and the second joint portion is formed by the bottom surface edge of the shell 21 extending outward, or is formed by the bottom surface edge of the shell 21 being recessed inward. The top wall of the shell 21 includes a first opening (not marked in the figure) communicating with the accommodating chamber, and the bottom wall includes a second opening (not marked in the figure) communicating with the accommodating chamber, and the first opening and the second opening are arranged opposite to each other; the side wall of the shell 21 includes a sliding hole 22 communicating with the accommodating chamber; the connecting cover 2 also includes: a rotatable flow control member located in the accommodating chamber of the shell 21; the flow control member includes a channel 231 that can be communicated with the first opening and the second opening; the channel 231, the first opening and the second opening can be communicated; the side wall of the flow control member includes a lever 232 that passes through the sliding hole 22 and extends to the outside of the side wall of the shell 21; the lever 232 is used to drive the flow control member to rotate in the accommodating chamber of the shell 21 to control whether the channel 231 is communicated with the first opening and the second opening.

[0049] The flow control member in the accommodating cavity of the shell 21 is rotated by using the lever 232. When the two ends of the channel 231 are connected to the first opening and the second opening respectively, a milk circulation conduit is formed. The milk in the shunt tube 5 is transported to the body of the sampling bottle 1 through the milk circulation conduit. The position of the lever 232 can be adjusted to adjust the size of the milk circulation conduit, that is, the degree of connection between the first opening, the second opening and the channel 231 can be adjusted, thereby changing the milk flow rate of milk flowing into the sampling bottle 1.

[0050] In a specific embodiment, a sealing strip (not shown in the figure) is provided between the inner wall of the housing 21 and the outer wall of the flow control member; the sealing strip can prevent milk from flowing between the housing 21 and the flow control member, thereby preventing milk from flowing out of the slide hole 22, and can also prevent milk from flowing into the body of the sampling bottle 1 from between the housing 21 and the flow control member. Specifically, two sealing strips can be provided, one on each side of the slide hole 22. Here, the flow control member will generate friction with the sealing strip when rotating, but this does not affect the rotation of the flow control member.

[0051] In a specific embodiment, the housing 21 and the flow control element are both cylindrical structures; Figure 2As shown, the radial cross-sections of the first opening, the second opening and the channel 231 can all be fan-shaped structures, and the centers of the first opening and the second opening in the fan-shaped structure can be located on the central axis of the housing 21, but are certainly not limited to being located on the central axis of the housing 21, and the arcs are respectively located on the inner side of the top edge and the inner side of the bottom edge of the housing 21. The sliding hole 22 is arranged on the side wall of the housing 21 in an arc shape with the center position of the cylindrical housing 21 as the center.

[0052] Specifically, the first opening may include a plurality of first sub-openings, the second opening may include a plurality of second sub-openings, and the channel 231 includes a plurality of sub-channels 231; the plurality of first sub-openings, the plurality of second sub-openings and the plurality of sub-channels 231 correspond to each other one by one, the plurality of first openings respectively penetrate from the outside of the top wall of the housing 21 to the accommodating cavity of the housing 21, the plurality of second sub-openings respectively penetrate from the outside of the bottom wall of the housing 21 to the accommodating cavity of the housing 21, and each of the sub-channels 231 respectively penetrates from the top wall to the bottom wall of the flow control member. Here, this is not shown in the structural diagram. When the plurality of first sub-openings, the plurality of second sub-openings and the plurality of sub-channels 231 are connected respectively, the flow rate of the milk entering the collection bottle from the shunt tube 5 is the largest. If it is desired to reduce the flow rate of the milk entering the collection bottle from the shunt tube 5, the lever 232 is driven to rotate the flow control member to connect some of the first sub-openings, some of the second sub-openings and some of the sub-channels 231. If it is desired to almost stop the flow rate of the milk entering the collection bottle from the shunt tube 5, the lever 232 is continued to be driven to rotate the flow control member to disconnect the first sub-opening, the second sub-opening and the sub-channels 231. Here, it can be said that when the first sub-opening, the second sub-opening and the sub-channels 231 are all disconnected, the milk stops flowing into the sampling bottle 1. Of course, a small amount of milk sample may flow into the sampling bottle 1, but this does not affect the use of the flow control member and will not affect the collection of the milk sample.

[0053] Furthermore, the outer side wall of the housing 21 may be marked corresponding to the plurality of sub-channels 231, for example, with a digital identifier, which may be a natural number such as 1, 2, 3, etc. When the lever 232 corresponds to different numbers, the degree of connectivity between the first opening, the second opening, and the channel 231 is also different. For example, when the lever 232 corresponds to 1, the first opening, the second opening, and the channel 231 are all connected; when the lever 232 corresponds to 2, the first opening, the second opening, and the channel 231 are 50% connected; when the lever 232 corresponds to 3, the first opening, the second opening, and the channel 231 are not connected.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
