Description

Technical Field

[0001] This utility model belongs to the field of milking machine technology, and specifically relates to a rotary milking machine. Background Technology

[0002] With the advancement of science and technology, manual milking has been gradually replaced by mechanical milking machines. However, since ordinary milking machines can only milk one cow at a time, the efficiency of milking is low, which leads to increased labor costs. As a result, rotary milking equipment has emerged. Rotary milking machines can milk multiple cows at the same time, greatly improving milking efficiency.

[0003] However, existing rotary milking machines have the following obvious drawbacks: they cannot clean the cow's udder in all directions; even those with cleaning measures cannot achieve thorough cleaning; and after cleaning, there is no drying process, requiring the cow to wait.

[0004] Among existing patents, application number 201810619204.1, entitled "An Intelligent Controlled Rotary Milking Machine for Cows," discloses a machine including a base, a motor, and several milking units. A microcontroller is mounted on a spacer rod, and the microcontroller is electrically connected to a water flow sensor. The milking units are mounted on a rotary table and located between the spacer rods. The water flow sensor is mounted on the milk outlet pipe between the milk cup and the milk storage tank. A reset switch is movably connected to an electric push rod, which is fixed to a vertical rod. The vertical rod is fixed to the spacer rod, and the electric push rod is electrically connected to the microcontroller. This application does not include cleaning the cow's udder, which affects the quality of the milk.

[0005] Another application, numbered 201910417074.8, entitled "A Rotary Milking Machine for Precisely Positioning the Cow's Tears," discloses a cleaning device. However, the cleaning device is fixed, and the water spray holes of the cleaning device are spaced out, which cannot completely cover the entire udder, resulting in blind spots during cleaning, which needs to be addressed. Utility Model Content

[0006] The purpose of this invention is to provide a rotary milking machine that thoroughly cleans and dries the cow's udder before milking to prevent impurities from entering the milk.

[0007] To solve the above problems, the present invention adopts the following technical solution:

[0008] The milking machine is equipped with railings to prevent the cows from moving around, support plates for the cows to stand on, and an operating platform for the cows to enter the railings.

[0009] A rotary milking machine includes a cleaning device and a drying device mounted on railings; the cleaning device is used to clean the cow's udder, and the drying device is used to dry the cleaned udder.

[0010] Furthermore, it also includes a lifting device for driving the cleaning device and the drying device to rise and fall. The lifting device includes a bracket fixedly connected to the railing, a lead screw rotatably connected to the bracket, a lead screw threaded to the lead screw, a guide sleeve fixedly connected to the lead screw, and a fixed plate fixedly connected to the lead screw. The drying device and the cleaning device are mounted on the fixed plate. The guide sleeve is slidably connected to the bracket.

[0011] Furthermore, the bracket is provided with a square tube; the guide sleeve is slidably connected to the square tube.

[0012] Furthermore, the cleaning device includes a turntable rotatably connected to the fixed plate, a connecting rod fixedly connected to the turntable, a retractable corrugated pipe fixedly connected to the connecting rod, and a cleaning pipe fixedly connected to the corrugated pipe; the cleaning pipe is an annular shape made of stainless steel square tubing; the cleaning pipe is fitted onto the outside of the cow's udder.

[0013] Furthermore, the cleaning pipe has a water outlet slit on the inner side near the cow's udder, with adjacent water outlet slits arranged alternately vertically.

[0014] Furthermore, the cleaning device also includes a tee fixedly connected to the corrugated pipe, a water inlet valve connected to one end of the tee, and a water pump fixedly connected to the water inlet valve.

[0015] Furthermore, the drying device includes an air inlet valve connected to the other end of the three-way valve and a blower connected to the air inlet valve.

[0016] Furthermore, the turntable and the fixed plate are rotatably connected by bearings, and the turntable and the fixed plate are locked together by L-bolts.

[0017] Compared with the prior art, the significant beneficial effects achieved by this utility model are as follows:

[0018] By using a lead screw and nut to drive the cleaning and drying devices to move up and down, the udders of dairy cows can be cleaned and dried.

[0019] By using staggered water outlets, water can be continuously sprayed around the cow's udder without any blind spots. After cleaning, the air is blown around the udder via a blower and water outlets. The staggered water outlets have less impact on the strength of the cleaning pipe than a full circle of water outlets. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components.

[0029] Example 1

[0030] like Figure 1 , Figure 2 As shown,

[0031] The existing milking machine is equipped with a fence 1 to prevent the cows from moving, a support plate 2 for the cows to stand on, and an operating platform 4 for the cows to enter the fence 1. The cows enter the support plate 2 of the fence 1 through the operating platform 4, and then the turntable is rotated to place the next cow in the next fence.

[0032] A rotary milking machine includes a cleaning device and a drying device mounted on a railing 1; the cleaning device is used to clean the udder of a dairy cow, and the drying device is used to dry the cleaned udder of the dairy cow.

[0033] It also includes a lifting device for driving the cleaning and drying devices to rise and fall. The lifting device includes a bracket 3 fixedly connected to the railing 1, a lead screw 31 rotatably connected to the bracket 3, a nut 34 threadedly driven by the lead screw 31, a guide sleeve 33 fixedly connected to the nut 34, and a fixed plate 36 fixedly connected to the nut 34. The drying and cleaning devices are mounted on the fixed plate 36. The guide sleeve 33 is slidably connected to the bracket 3. Rotation of the lead screw 31 causes the nut 34 to slide up and down along the guide sleeve 33, thereby driving the cleaning device to clean the cow's udder.

[0034] The bracket 3 is equipped with a square tube 32; the guide sleeve 33 is slidably connected to the square tube 32. The inner cross-section of the guide sleeve 33 is square, which fits the square tube 32, thus preventing the guide sleeve 33 from rotating and allowing it to move only up and down along the square tube 32, thereby restricting the lead screw nut 34 to move only up and down along the lead screw 31. The bracket 3 is equipped with a motor 35, which has forward and reverse rotation and braking functions.

[0035] The cleaning device includes a turntable rotatably connected to the fixed plate 36, a connecting rod 39 fixedly connected to the turntable, a retractable corrugated pipe 40 fixedly connected to the connecting rod 39, and a cleaning pipe 41 fixedly connected to the corrugated pipe 40. The cleaning pipe 41 is annular, made of stainless steel square tubing. The cleaning pipe 41 is fitted over the outside of the cow's udder. Stainless steel is used to prevent rust and secondary contamination of the cow's udder. The annular cleaning pipe 41 can fit over the entire udder for thorough cleaning. Before the cow enters the enclosure 1, the turntable rotates to position the cleaning pipe 41 parallel to the enclosure 1, preventing it from obstructing the cow's entry. After the cow is in position, the turntable is rotated again to position the cleaning pipe 41 below the udder, thus preventing the cleaning pipe 41 from restricting the cow's movement.

[0036] like Figure 4 As shown, the cleaning pipe 41 has a water outlet slit 42 on the inner side near the cow's udder;

[0037] The cleaning device also includes a tee fixedly connected to the bellows 40, a water inlet valve connected to one end of the tee, and a water pump 44 fixedly connected to the water inlet valve.

[0038] The drying device includes an air inlet valve connected to the other end of the three-way valve and a blower 43 connected to the air inlet valve.

[0039] The turntable and the fixed plate 36 are rotatably connected by a bearing 37, and a locking device is provided between the turntable and the fixed plate 36; the locking device prevents the cleaning pipe 41 from rotating arbitrarily, which would affect the movement of the dairy cow.

[0040] The working process of this utility model,

[0041] After the cow is positioned on support plate 3, the turntable is rotated, the locking device is released, and the turntable is rotated so that the cleaning pipe 41 is positioned below the cow's udder. The flexible and extendable corrugated pipe 40 is then manually adjusted to position the cleaning pipe 41 directly below the cow's udder. The motor is started, and the water inlet valve is opened, activating the water pump 44. Clean water is then passed through the water outlet slit 42 to clean the area around the cow's udder. After cleaning, the water pump 44 and water inlet valve are closed, and the air inlet valve and blower 43 are opened to dry the area around the udder. In winter, a warm air blower can be used, and in summer, a cool air blower can be used to increase comfort and prevent discomfort and agitation in the cow during milking. The water used for cleaning is heated to 36-40 degrees Celsius in winter to prevent agitation in the cow.

[0042] Example 2

[0043] The structure of this embodiment is largely the same as that of Embodiment 1.

[0044] The difference is that,

[0045] like Figure 4 As shown, the adjacent water outlets 42 are arranged in an alternating pattern, which avoids opening the entire circular slit and affecting the strength of the cleaning pipe 41. From the top view, the two ends of the adjacent water outlets 42 overlap each other, so that water can be sprayed all around the cow's udder without any blind spots. Combined with the up-and-down movement of the lifting device, the entire cow's udder can be cleaned and dried.

[0046] Example 3

[0047] The structure of this embodiment is largely the same as that of embodiment 2.

[0048] The difference is that,

[0049] like Figure 2 As shown, the turntable and the fixed plate 36 are locked together by L-bolts 38. The L-bolts 38 limit the position of the turntable and the fixed plate 36. When the cleaning pipe 41 is not in use, it is adjusted to be parallel to the fence 1, that is, in the same direction as the cow's walking, and then locked with bolts to prevent the cow from being restricted from moving forward when it enters the fence 1. When the cow enters the fence 1, the bolts are loosened, the cleaning pipe 41 is rotated to be directly under the cow's udder, and then the bolts are locked again to clean and dry the cow.

[0050] Currently, the technical solution of this application has undergone pilot testing, which is a small-scale experiment before the product is mass-produced. After the pilot testing was completed, a user survey was conducted on a small scale, and the survey results showed that user satisfaction was high. Now, preparations have begun for the formal production and industrialization of the product (including intellectual property risk warning surveys).
