Description

Technical Field

[0001] This utility model relates to the field of milking machine technology, and more specifically to a central rotating device. Background Technology

[0002] Rotary milking machines are core equipment for modern large-scale dairy farms to achieve efficient and automated milking operations. Their basic working principle is that cows waiting to be milked enter a slowly rotating circular turntable in sequence. During one rotation, the machine automatically completes a series of operations, including teat cleaning, cup-setting, milking, and post-milking septic baths. Finally, the cows leave the turntable near the entrance. This continuous flow operation mode greatly improves milking efficiency and reduces labor costs.

[0003] In a rotary milking machine, the central rotating mechanism is the core hub of the entire system. Located at the geometric center of the turntable, it plays a crucial role in connecting the stationary plant infrastructure with the rotating turntable. Its core function is to achieve continuous and sealed transfer of media such as water, electricity, gas, vacuum, and milk between the stationary and rotating pipelines.

[0004] However, after a period of use, carbon residue accumulates on the slip rings of existing center rotating devices, causing arcing and short circuits in the cables, which seriously affects the safety of the power system. Therefore, how to provide a center rotating device with high safety is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0022] The electric rotary kettle 8 is connected to the end of the vacuum rotating part 5 away from the vacuum fixing part 4. One end of the electric rotary kettle 8 is provided with a communication cable outlet. The communication cable 11 inside the electric rotary kettle 8 extends out of the communication cable outlet and is electrically connected to the communication cable of the milking machine through a double carbon brush.

[0023] During use, the connecting flange 3 is fixed on the central base on site to ensure the stability of the central rotating device. The electric rotating vessel 8 provides communication signals to the milking machine's turntable to control the movement of the turntable. The communication cable 11 inside the electric rotating vessel 8 is connected to the milking machine's communication cable through a double carbon brush to ensure the safety of the electric rotating vessel 8 and the rotating device.

[0024] Vacuum inlet 13 is connected to a vacuum pump. The vacuum pump introduces air into the vacuum fixing part 4 and drives the air into the rotary distributor. After being conveyed by the rotary distributor, the air enters the vacuum rotating part 5 and then flows out through vacuum inlet 13 to be delivered into the milking machine to ensure that the milk is squeezed out smoothly.

[0025] In some embodiments, the vacuum fixing part 4 and the vacuum rotating part 5 are made of stainless steel, which ensures the sealing of the vacuum fixing part 4 and the vacuum rotating part 5 and prevents gas leakage.
