Description
Technical Field
[0001] This utility model relates to the field of livestock machinery technology, and in particular to a milk liner cleaning tray. Background Technology
[0002] Currently, the cleaning trays for milking machines used in animal husbandry on the market are generally as described in the technical solution of Chinese Patent Application No. 201820273743X, entitled "A Folding Cleaning Tray for Milking Machines". The cleaning seat on the tray block has a bowl-shaped structure and a cavity is provided on the cleaning seat. When in use, the head of the milk liner is squeezed into the cavity of the cleaning seat, and the tail of the milk liner is suspended in the air. As a result, when water is injected for cleaning, the tail of the milk liner is prone to shaking under the impact of water, causing the milk liner to easily detach from the cleaning seat. This results in poor connection stability, low cleaning efficiency, and inconvenience in use. Utility Model Content
[0003] The purpose of this utility model is to provide a milk liner cleaning tray, which has the advantages of simple structure, reasonable design, good connection stability between milk liner and cleaning seat during use, high cleaning efficiency and convenient use.
[0004] The technical solution of this utility model is implemented as follows: a milk liner cleaning tray includes a tray block and a cleaning seat; a water storage cavity is formed inside the tray block, and a water inlet and a water outlet are formed on the tray block. The water outlet is located on the top surface of the tray block, and both the water inlet and the water outlet are connected to the water storage cavity; specifically, the cleaning seat is provided from top to bottom with a mounting column, a spray head, a locking ring groove, a base, and a connecting column; a water passage cavity is formed inside the cleaning seat; the spray head has a structure with a cross-sectional radius that gradually increases from top to bottom, and a spray hole communicating with the water passage cavity is formed on the circumferential surface of the spray head; the connecting column passes through the water outlet of the tray block and enters the water storage cavity, and the connecting column is connected to the tray block. A water inlet is formed on the connecting column, and the water inlet connects the water passage cavity and the water storage cavity.
[0005] This design utilizes a cylindrical cleaning seat, which, from top to bottom, comprises a mounting column, a spray head, a retaining ring groove, a base, and a connecting column. In use, the milk liner is mounted on the cleaning seat, with its milking nozzle extending beyond the spray head and nestled within the retaining ring groove, ensuring a tight fit between the milking nozzle and the bottom of the groove. During cleaning, water enters the water storage chamber through the inlet of the tray block, then flows through the outlet and the inlet of the cleaning seat into the water passage chamber, finally being sprayed out through the spray nozzle to clean the milk liner. This structure, where the milk liner is mounted on the cleaning seat, provides support for the milk liner, preventing it from wobbling at the tail end during cleaning and thus preventing it from detaching from the cleaning seat. Furthermore, the smaller gap between the inner wall of the milk liner and the cleaning seat increases the water flow velocity, creating a stronger flushing force and resulting in better cleaning and significantly improved cleaning efficiency.
[0006] Furthermore, a large head is formed at the top of the sleeve column on the cleaning seat, and the cross-sectional radius of the large head is larger than the cross-sectional radius of the sleeve column.

[0008] Furthermore, the nozzle is a three-dimensional rotating body. The generatrix of the nozzle is divided into a first segment, a second segment, and a third segment from top to bottom. The first and second segments are both arcs, and the radius of the first segment is smaller than that of the second segment. The third segment is a straight line and is parallel to the central axis of the nozzle. The first, second, and third segments respectively constitute the first, second, and third rotating surfaces. The first water spray hole is located on the intersection line of the first and second rotating surfaces, and the second water spray hole is located on the intersection line of the second and third rotating surfaces.
[0009] Furthermore, a connecting nut is provided in the water outlet hole of the tray block, and the connecting post of the cleaning seat is threadedly connected to the connecting nut. A sealing ring is also clamped between the bottom surface of the base of the cleaning seat and the tray block, and the connecting post passes through the sealing ring.
[0010] Furthermore, the tray block includes an upper disc and a lower disc; the upper disc and the lower disc are connected to form the water storage cavity. The upper disc is a frustum-shaped shell with an open bottom. Several water outlet holes are formed on the side of the upper disc. All water outlet holes are evenly distributed around the central axis of the upper disc. There are several cleaning seats. All cleaning seats correspond one-to-one with all water outlet holes. The cleaning seats are connected to the upper disc at an incline.
[0011] Furthermore, the pallet block is equipped with a rotating arm; the rotating arm has a rotating hole and a positioning pin; the rotating hole is an elongated hole; the positioning pin is located between the rotating hole and the pallet block, and the axis of the positioning pin is parallel to the axis of the rotating hole. Both the axis of the positioning pin and the axis of the rotating hole are parallel to the horizontal plane; it also includes a bracket; the bracket includes two clamping plates, which are fixed together to form a rotating clamping space between the two clamping plates, and the front end face of each clamping plate is an arc-shaped surface; the rotating arm of the pallet block is inserted into the rotating clamping space, and the rotating clamping space has a central axis passing through the rotating hole of the rotating arm.

Each clamp has a first positioning recess and a second positioning recess, and the openings of the first and second positioning recesses are both facing upwards. The first positioning recess is located on the top surface of the clamp and is used for the end of the positioning pin to be inserted and positioned when the pallet is in the folded state. The second positioning recess is located on the front end face of the clamp and is an arc-shaped hole recessed towards the first positioning recess. The second positioning recess of each clamp is used for the end of the positioning pin to be inserted and positioned when the pallet is in the working state.
[0012] Furthermore, the support also includes a partition and a fixing mechanism; the fixing mechanism includes two half-hoops, the rear ends of which are connected by screws; the rear ends of two clamping plates are located between the front ends of the two half-hoops, and the partition is provided between the rear ends of the two clamping plates; the front ends of the two half-hoops, the rear ends of the two clamping plates, and the partition are fixed together by screws to form the rotating clamping space between the two clamping plates and the clamping space between the two half-hoops; the partition is a long strip structure, the length of the partition is arranged along the vertical direction, and a limiting part is provided at the top of the partition that extends into the rotating clamping space, the limiting part being used to limit the maximum downward rotation of the pallet block.

Detailed Implementation
[0022] Example 1
[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a milk liner cleaning tray of this embodiment includes a tray block 1 and a cleaning seat 2. A water storage cavity is formed inside the tray block 1, and a water inlet 11 and a water outlet are formed on the tray block 1. The water outlet is located on the top surface of the tray block 1, and both the water inlet 11 and the water outlet are connected to the water storage cavity. The cleaning seat 2 is provided with a mounting column 21, a spray head 22, a locking ring groove 23, a base 24, and a connecting column 25 from top to bottom. A water passage cavity is formed inside the cleaning seat 2. The spray head 22 has a structure with a cross-sectional radius that gradually increases from top to bottom, and a spray hole communicating with the water passage cavity is formed on the circumferential surface of the spray head 22. The connecting column 25 passes through the water outlet of the tray block 1 and enters the water storage cavity. The connecting column 25 is connected to the tray block 1, and a water inlet is formed on the connecting column 25, which connects the water passage cavity and the water storage cavity. In use, the milk liner 3 is fitted onto the cleaning seat 2, with the milking nozzle of the milk liner 3 nested in the retaining ring groove 23, extending beyond the spray head 22. The milking nozzle of the milk liner 3 is tightly fitted to the bottom of the retaining ring groove 23. During the cleaning process, water enters the water storage chamber through the water inlet 11 of the tray block 1, then enters the water passage chamber through the water outlet and the water inlet of the cleaning seat 2, and finally is sprayed out through the spray nozzle of the spray head 22 to clean the milk liner 3. This structure, where the milk liner 3 is fitted onto the cleaning seat 2, provides support for the milk liner 3 via the mounting column 21, preventing the tail of the milk liner 3 from shaking during cleaning and making it less likely for the milk liner 3 to detach from the cleaning seat 2. Furthermore, the smaller gap between the inner wall of the milk liner 3 and the cleaning seat 2 increases the water flow velocity, creating a stronger flushing force and resulting in better cleaning and significantly improved cleaning efficiency.
[0024] like Figure 2 As shown, a large head 26 is also formed at the top of the sleeve column 21 on the cleaning seat 2. The cross-sectional radius of the large head 26 is larger than that of the sleeve column 21. With this structure, the water flow velocity increases again when it passes through the large head 26 during cleaning, thereby further improving the cleaning efficiency.
[0025] To make the structure of the spray head 22 more reasonable, such as Figure 2 As shown, the spray head 22 has four spray holes, all of which are evenly distributed around the central axis of the cleaning seat 2. Below each of the two opposing first spray holes 221, there is a second spray hole 222, the diameter of which is smaller than that of the first spray hole 221. By providing the first spray holes 221 and second spray holes 222 on the spray head 22, and ensuring that the first and second spray holes 221 are not coplanar, the interior of the milk liner 3 can be cleaned thoroughly without any blind spots, making it easier to clean the milk liner 3 completely.
[0026] To enhance the rinsing power of this milk liner cleaning tray during use, such as... Figure 2 As shown, the spray head 22 is a three-dimensional rotating body. The generatrix of the spray head 22 is divided into three segments from top to bottom: a first segment, a second segment, and a third segment. The first and second segments are both arcs, with the radius of the first segment being smaller than that of the second segment. The third segment is a straight line, parallel to the central axis of the spray head 22. The first, second, and third segments respectively constitute the first rotating surface 223, the second rotating surface 224, and the third rotating surface 225. The first water spray hole 221 is located on the intersection line of the first rotating surface 223 and the second rotating surface 224, and the second water spray hole 222 is located on the intersection line of the second rotating surface 224 and the third rotating surface 225. This structure allows the first water spray hole 221 and the second water spray hole 222 to be located in two different directions, resulting in stronger water scouring force when spraying from the spray head 22 during operation, which is beneficial for improving cleaning efficiency.
[0027] To make the connection structure between the cleaning seat 2 and the tray block 1 more reasonable, a connecting nut is provided in the water outlet hole of the tray block 1, and the connecting post 25 of the cleaning seat 2 is threadedly connected to the connecting nut, such as... Figure 2 As shown, the connecting post 25 of the cleaning seat 2 is provided with external threads, and a sealing ring is also clamped between the bottom surface of the base part 24 of the cleaning seat 2 and the tray block 1, and the connecting post 25 passes through the sealing ring.
[0028] To make the structure of tray block 1 more reasonable and to ensure that the water volume reaching each washing seat 2 after passing through tray block 1 is uniform, so as to achieve efficient cleaning of milk liner 3, such as... Figure 1 , Figure 3 As shown, the tray block 1 includes an upper disc 12 and a lower disc; the upper disc 12 and the lower disc are connected to form the water storage cavity. The upper disc 12 is a frustum-shaped shell with an open bottom. Four water outlet holes are formed on the side of the upper disc 12. All water outlet holes are evenly distributed around the central axis of the upper disc 12. There are four cleaning seats 2. All cleaning seats 2 correspond one-to-one with all water outlet holes. The cleaning seats 2 are connected to the upper disc 12 at an incline.
[0029] To make the structure of the milk liner cleaning tray more reasonable, such as Figure 3As shown, this milk liner cleaning tray also includes a mounting base 4; a tray block 1 is mounted on the top surface of the mounting base 4, and a water inlet hole 11 is provided on the top surface of the tray block 1. Two upright plates 5 are mounted on the top surface of the mounting base 4; the two upright plates 5 are arranged side by side, and each upright plate 5 is perpendicular to the top surface of the mounting base 4. A guide hole 51 is provided on the upright plate 5, and the guide hole 51 is an arc-shaped hole. In use, the mounting base 4 is mounted on the milking device through a rotating column passing through the guide hole 51 of the two upright plates 5. This milk liner cleaning tray can rotate relative to the rotating column through the guide hole 51 to switch between the use state and the folded state. In the use state, the top surface of the mounting base 4 is parallel to the horizontal plane, and in the folded state, the top surface of the mounting base 4 is perpendicular to the horizontal plane.
[0030] To ensure the milk liner cleaning tray remains positioned when folded, and to prevent it from automatically switching to the usable state under gravity and obstructing milking operations, such as... Figure 3 As shown, the guide hole 51 of each upright plate 5 is located on the top surface of one end of the mounting base 4, and a fastener 6 is installed on the bottom surface of the other end of the mounting base 4. In use, the milking device is equipped with a locking device that can engage with the fastener 6.
[0031] Example 2
[0032] The difference between this embodiment and Embodiment 1 lies in the structure of how the tray block 1 is installed on the milking device during use. Specifically, as follows: Figure 5 , Figure 6 , Figure 7As shown, a tray block 1 is equipped with a rotating arm 7, and a water inlet hole 11 is provided on the bottom surface of the tray block 1; the rotating arm 7 is provided with a rotating hole 71 and a positioning pin 72; the rotating hole 71 is an elongated hole; the positioning pin 72 is located between the rotating hole 71 and the tray block 1, and the axis of the positioning pin 72 is parallel to the axis of the rotating hole 71. Both the axis of the positioning pin 72 and the axis of the rotating hole 71 are parallel to the horizontal plane; a bracket 8 is also included, and the rear end of the bracket 8 is used to connect to the milking device during use; the bracket 8 The system includes two clamping plates 81, both parallel to the horizontal plane and fixed together, forming a rotating clamping space 87 between them. The front end face of each clamping plate 81 is arc-shaped. The rotating arm 7 of the tray block 1 is inserted into the rotating clamping space 87, and the rotating clamping space 87 has a central shaft 83 passing through a rotating hole 71 of the rotating arm 7. To reduce friction, a roller 84 is provided between the central shaft 83 and the rotating hole 71. The tray block 1 moves relative to the bracket 8 to switch between a used state and a folded state. Switching between; the front end face of each clamping plate 81 is arranged around the axis of the central shaft 83; each clamping plate 81 has a first positioning recess 811 and a second positioning recess 812, the openings of the first positioning recess 811 and the second positioning recess 812 are both set upwards; the first positioning recess 811 is set on the top surface of the clamping plate 81, and the first positioning recess 811 of each clamping plate 81 is used for the end of the positioning pin 72 to be inserted and positioned when the pallet block 1 is in the folded state. When the pallet block 1 is in the folded state, the length direction of the rotation hole 71 of the rotating arm 7 is perpendicular to the horizontal plane; the second positioning recess 812 is set on the front end face of the clamping plate 81, and the second positioning recess 812 is specifically located in front of and above the central shaft 83. The second positioning recess 812 is an arc-shaped hole set concave to the first positioning recess 811. The second positioning recess 812 of each clamping plate 81 is used for the end of the positioning pin 72 to be inserted and positioned when the pallet block 1 is in use. When the pallet block 1 is in use, the length direction of the rotation hole 71 of the rotating arm 7 is parallel to the horizontal plane. This structure can be folded up when not in use, without hindering other work.
[0033] To make the structure of bracket 8 more reasonable, such as Figure 5 , Figure 6 , Figure 7As shown, the bracket 8 also includes a partition 85 and a fixing mechanism 86; the fixing mechanism 86 includes two half-hoops 861, the rear ends of which are connected by screws; the rear ends of the two clamping plates 81 are located between the front ends of the two half-hoops 861, and the partition 85 is provided between the rear ends of the two clamping plates 81. The front ends of the two half-hoops 861, the rear ends of the two clamping plates 81, and the partition 85 are fixed together by screws to form the rotation clamping space 87 between the two clamping plates 81 and the clamping space between the two half-hoops 861; the partition 85 The partition 85 has a long, narrow structure, with its length extending vertically. To prevent the positioning pin 72 from failing to align with the second positioning recess 812 and causing the bottom surface of the tray 1 to collide with the milking device during the downward rotation of the tray block 1 to the working state, a limiting part 851 extending into the rotating clamping space 87 is provided at the top of the partition 85. This limiting part 851 limits the maximum downward rotation of the tray block 1. When the tray block 1 rotates to its maximum downward rotation, the limiting part 851 blocks the end of the rotating arm 7 away from the tray block 1. With this structure, during use, the clamping space of the fixing mechanism 86 clamps a mounting post 9 whose axis is perpendicular to the horizontal plane, thus achieving installation on the milking device.
