Description

Technical Field

[0001] This utility model relates to the field of livestock machinery technology, and in particular to a milk collector. Background Technology

[0002] Currently, commercially available milk collectors for dairy cows consist of a cup body and a lid. The lid is placed on the cup body and connected by a connecting post and a connecting nut, clamping the cup body between the lid and the nut to secure the cup body and lid together, forming the milk collection chamber. To allow milk to flow out of the milk collection chamber, a milk outlet is provided on the side of the cup body, and the bottom of the cup body is made into a slope that gradually slopes downwards towards the milk outlet. This structure requires a milk outlet and a through hole for the connecting post to pass through the cup body, making the structure relatively complex, inconvenient to clean, and costly to produce. Utility Model Content

[0003] The purpose of this utility model is to provide a milk collector that has the advantages of simple structure, reasonable design, easy cleaning, low production cost and high production efficiency.

[0004] The technical solution of this utility model is implemented as follows: A milk collector includes a cup body, a cup lid, a connecting post, and a connecting nut; the cup lid is placed on the mouth of the cup body, and the cup lid and the cup body are assembled to form a milk collection chamber, with the cup lid having a milk inlet communicating with the milk collection chamber; the connecting post is vertically arranged, with its top end fixedly connected to the cup lid, and its bottom end passing through a through hole provided in the cup body; the connecting nut is threadedly connected to the bottom end of the connecting post, so that the cup body is clamped and fixed between the cup lid and the connecting nut; in particular, a column cavity is formed inside the connecting post, a milk passage hole communicating with the milk collection chamber is formed on the connecting post, and a milk outlet communicating with the column cavity is formed on the bottom end face of the connecting post.

[0005] In this design, the milk outlet of the connecting column is connected to a vacuum-sealed milk outlet pipe, and the milk inlet of the cup lid is connected to the milk cup used for milking via a pipe. During milking, an external vacuum device creates a vacuum in the milk collection chamber, which is then transmitted to the milk cup through the milk inlet. The vacuum-sealed milk cup squeezes milk from the nipple and flows into the milk collection chamber. Because the connecting column also features a cylindrical cavity and a milk passage hole, the milk in the milk collection chamber flows through the milk passage hole and the cylindrical cavity before exiting from the milk outlet. Finally, the milk flows through the milk pipe to the milk storage container. This design only requires a through hole in the cup body for the connecting column to pass through, greatly simplifying the cup's structure, making cleaning easier, and improving production efficiency.

[0006] Furthermore, a bent section is integrally formed on the bottom surface of the connecting nut; the bent section is made of a rigid material; the bottom end of the connecting post is inserted into the bent section.

[0007] Furthermore, the connecting column has at least two milk passage holes; all milk passage holes are evenly distributed around the central axis of the connecting column; each milk passage hole is an elongated hole, the length direction of each milk passage hole is parallel to the central axis of the connecting column, and each milk passage hole extends from the middle of the connecting column to the passage hole of the cup body.

[0008] Furthermore, the connecting column also has reinforcing ribs that divide the milk passage hole into upper and lower parts.

[0009] Furthermore, the cup body has a funnel-shaped structure; a first sealing ring is sandwiched between the top surface of the connecting nut and the cup body.

[0010] Furthermore, the cup body is made of transparent glass; the cup lid, connecting post, and connecting nut are all made of stainless steel; a connecting pipe is formed on the cup lid; one opening of the connecting pipe is the milk inlet, and the other opening of the connecting pipe is connected to the milk collection chamber.

[0012] Furthermore, a raised ring is formed on the connecting post; a through hole is formed on the cup lid; the top end of the connecting post passes through the through hole of the cup lid; and a clamping nut is also included; the clamping nut is threadedly connected to the top end of the connecting post, and the cup lid is clamped and fixed between the clamping nut and the raised ring of the connecting post.

[0013] Furthermore, this emulsion collector also includes a gas distribution valve; a first through hole is formed on the gas distribution valve, and a positioning recess is formed on the bottom surface of the gas distribution valve; the gas distribution valve is located above the cup lid, and the connecting post is set through the first through hole of the gas distribution valve, and the gas distribution valve is clamped between the clamping nut and the top surface of the cup lid; a positioning protrusion is formed on the top surface of the cup lid and inserted into the positioning recess.

[0014] Furthermore, a third sealing ring is installed between the bottom surface of the gas distribution valve and the top surface of the cup lid; a fourth sealing ring is installed between the bottom surface of the cup lid and the protruding ring of the connecting post, and both the third and fourth sealing rings are fitted onto the connecting post.

[0015] Furthermore, this milk collector also includes a hook component; the hook component has a second through hole and a third through hole; the top surface of the gas distribution valve has a fixing screw hole; the hook component is located above the gas distribution valve, and the top end of the connecting column passes through the second through hole of the hook component, and the hook component is clamped between the clamping nut and the top surface of the gas distribution valve; it also includes a fixing screw; one end of the fixing screw passes through the third through hole of the hook component and is locked into the fixing screw hole of the gas distribution valve.

Detailed Implementation

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, a milk collector according to this embodiment includes a cup body 1, a cup lid 2, a connecting post 3, and a connecting nut 4. The cup lid 2 covers the mouth of the cup body 1, and the cup lid 2 and the cup body 1 are assembled to form a milk collection chamber 5. The cup lid 2 has a milk inlet that communicates with the milk collection chamber 5. The connecting post 3 is arranged vertically, and the top end of the connecting post 3 is fixedly connected to the cup lid 2. The bottom end of the connecting post 3 passes through a through hole provided in the cup body 1. The connecting nut 4 is threadedly connected to the bottom end of the connecting post 3, so that the cup body 1 is clamped and fixed between the cup lid 2 and the connecting nut 4. A column cavity 31 is formed inside the connecting post 3. The cross-sectional diameter of the column cavity 31 is about 8mm. A milk passage hole 32 communicating with the milk collection chamber 5 is formed on the connecting post 3. A milk outlet 33 communicating with the column cavity 31 is formed on the bottom end face of the connecting post 3. In use, the milk outlet 33 of the connecting column 3 is connected to the milk outlet pipe under vacuum, and the milk inlet of the cup lid 2 is connected to the milk cup used for milking through a pipe. During milking, an external vacuum device creates a vacuum in the milk collection chamber 5, which is then transmitted to the milk cup through the milk inlet. The vacuum in the milk cup squeezes the milk out of the nipple and flows into the milk collection chamber 5. Because the connecting column 3 also has a column cavity 31 and a milk passage hole 32, the milk in the milk collection chamber 5 can pass through the milk passage hole 32 and the column cavity 31 in sequence before flowing out from the milk outlet 33. Finally, the milk flows through the milk pipe to the milk storage container. This milk collector only needs to form a through hole on the cup body 1 for the connecting column 3 to pass through, which greatly simplifies the structure of the cup body 1, makes cleaning easier, and improves production efficiency.

[0024] To facilitate tightening of the connecting nut 4 and to guide the milk flowing from the milk outlet 33, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, a bent tube portion 41 is integrally formed on the bottom surface of the connecting nut 4; the bent tube portion 41 is made of a rigid material; the bottom end of the connecting post 3 is inserted into the bent tube portion 41. With this structure, the bent tube portion 41 can be used as a handle to rotate the connecting nut 4, making the installation of the connecting nut 4 tool-free and easier to assemble; during use, the end of the bent tube portion 41 away from the connecting nut 4 is connected to the milk outlet pipe which is in a vacuum state.
