The image shows a portable, single-bucket milking machine, which is used to extract milk from cows or buffaloes. These machines are designed to apply a constant vacuum to the teats, mimicking the sucking action of a calf, and then convey the milk to a container. Key components and features of the machine include:

Vacuum Pump:

This is a crucial part of the system, creating the vacuum necessary to extract milk.
Pulsator:

The pulsator ensures periodic squeezing of the teats to maintain blood circulation, mimicking the natural milking process.
Milk Claw and Teat Cups:

The claw connects the teat cups, which are attached to the cow’s teats. These cups have an inner liner that gently massages the teat while extracting milk.
Milk Container:

The extracted milk is collected in a stainless steel bucket, which is part of the portable unit.
