DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the utility model clearer, the technical scheme in the utility model will be described clearly and completely in combination with the drawings in the utility model below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0025] As potential carriers of pathogenic bacteria, cows may carry Brucella bacteria and other various pathogenic bacteria such as Escherichia coli and Staphylococcus aureus. During the traditional manual milk pipe docking process, the staff need to frequently manually contact the milk pipe, which exposes them directly to a high-risk environment of pathogenic bacterial infection. Frequent direct contact increases the possibility of pathogenic bacteria spreading to the human body, causing the staff to face a high risk of Brucella infection. Brucella not only causes physical pain to patients, such as fever, sweating, joint pain and other symptoms, but also may cause long-term health problems, seriously affecting the physical health and quality of life of practitioners. At the same time, infection with other pathogenic bacteria may also cause various diseases, further threatening the health of practitioners.

[0026] Manual operation of the milk pipe docking has problems in precision and sealing. Since manual operation is greatly affected by human factors, it is difficult to achieve complete precision during each docking, which may result in loose connection of the milk pipe and gaps. Such a non-sealed state is prone to cause milk leakage, resulting in waste of milk. In addition, the leaked milk not only reduces the actual yield, but also may contaminate the surrounding environment, increasing the risk of cross infection. More seriously, the non-sealed milk pipe allows external air, dust, impurities and the like to enter the milk delivery system, causing the milk to be contaminated and affecting the quality of the milk. Once the quality of the milk does not meet the standards, it not only cannot meet the market demand, but also may cause economic losses to the dairy enterprises and damage the reputation of the enterprises.

[0027] As shown in Figure 1 The milk pipe docking device of the utility model embodiment comprises a three-dimensional moving mechanism 1 and a docking mechanism 2. The docking mechanism 2 comprises a quick connector 21 and a driving assembly 22. The quick connector 21 comprises a male head body, a female head body 211 and a pressing handle 212 hinged to the female head body 211. An inner concave curved surface is arranged on the male head body. An outer convex curved surface matched with the inner concave curved surface is arranged on the pressing handle 212. A through slot is arranged on the female head body 211 at a position corresponding to the outer convex curved surface. The outer convex curved surface passes through the through slot and contacts the inner concave curved surface. The male head body is suitable for being installed on a milk cart. The female head body 211 is installed on the output end of the three-dimensional moving mechanism 1. The driving assembly 22 is installed on the female head body 211 and is in transmission connection with the pressing handle 212. The driving assembly 22 is used to drive the pressing handle 212, so as to realize quick docking and separation of the male head body and the female head body 211.

[0028] Exemplarily, the female head body 211 is provided with a hinged seat which can be integrally formed with the female head body 211 or welded or arranged on the female head body 211 through other connecting manners, and a through slot is arranged on the female head body 211 inside the hinged seat, and the pressing handle 212 is hinged on the female head body 211 through the hinged seat. In an embodiment, the pressing handle 212 is hinged on the hinged seat through a knurled pin, a through hole is arranged on the pressing handle 212 which matches the cylindrical surface of the knurled pin, and a mounting hole is arranged on the hinged seat which matches the knurled part of the knurled pin, the knurled pin is fixedly installed on the hinged seat, and the pressing handle 212 can rotate relative to the knurled pin; by arranging the knurled pin, the connection between the pressing handle 212 and the hinged seat is more firm.

[0029] It should be noted that the three-dimensional moving mechanism 1 is used to realize the movement in X, Y and Z directions. In other words, the three-dimensional moving mechanism 1 is used to adjust the spatial position of the docking mechanism 2, so that the female head body 211 can accurately align with the male head body on the milk cart.

[0030] In actual application, when the milk conveying pipe needs to be docked, the three-dimensional moving mechanism 1 moves the docking mechanism 2 to the position of the milk cart, so that the female head body 211 can align with the male head body on the milk cart. Then, the driving assembly 22 drives the pressing handle 212 to rotate, so that the outer convex arc surface passes through the through slot and contacts with the inner concave arc surface on the male head body, realizing the docking of the female head body 211 and the male head body. When the milk conveying pipe needs to be separated, the driving assembly 22 drives the pressing handle 212 to rotate reversely, so that the outer convex arc surface is separated from the inner concave arc surface, and the female head body 211 and the male head body can be quickly separated. In this way, through the cooperative work of the three-dimensional moving mechanism 1 and the docking mechanism 2, the quick and stable docking of the male head body and the female head body 211 is realized.

[0034] It should be noted that the Z-axis moving assembly 13 is the part of the three-dimensional moving mechanism 1 that realizes the vertical direction (Z-axis) movement. Among them, the frame 131 is the support structure of the Z-axis moving assembly 13, which is usually made of high-strength and lightweight materials (such as aluminum alloy) to ensure the stability and lightness of the overall structure. The frame 131 provides mounting space for the lifting module 133 and the mounting platform 132. The mounting platform 132 usually adopts a flat plate structure, and the surface is precisely machined to ensure the installation accuracy and stability of the female head body 211. The mounting platform 132 is connected with the frame 131 through the lifting module 133 to realize the vertical movement. The mounting platform 132 provides stable support for the female head body 211 and moves up and down with the movement of the lifting module 133 to adjust the vertical position of the female head body 211. Among them, the lifting module 133 can adopt multiple types, such as a lead screw lifter, an air cylinder, an electric push rod or a linear motor, etc.

[0036] In an optional embodiment, as shown, Figure 1 As shown, the milk conveying pipe docking device further comprises a pipe storage mechanism 3, the pipe storage mechanism 3 comprises a rope 32, a mounting bracket 33 and a rope winding and unwinding assembly 31, the mounting bracket 33 is mounted on the X-axis moving assembly 11, the mounting bracket 33 is arranged opposite to the frame 131, the rope winding and unwinding assembly 31 is mounted on the mounting bracket 33, the first end of the rope 32 is mounted on the rope winding and unwinding assembly 31, and the second end of the rope 32 is mounted on the frame 131; wherein the female head body 211 is connected with a milk inlet pipe 23, the milk inlet pipe 23 is arranged along the length direction of the rope 32 and connected with the rope 32. Exemplarily, a plurality of pull rings are arranged along the length direction of the rope 32, the pull rings are sleeved on the rope 32 and connected with the milk inlet pipe 23.

[0037] It should be noted that during the milk pipe docking process, when the three-dimensional moving mechanism 1 adjusts the position of the female head body 211, the pipe storage mechanism 3 works synchronously. The rope winding and unwinding assembly 31 unwinds or winds the rope 32 in time according to the movement distance of the female head body 211 in the X-axis direction, so that the milk inlet pipe 23 can be extended or stored along the length direction of the rope 32.
