Problems solved by technology
[0002] Automatic milking technology simulates manual milking action through intermittent vacuum operation to achieve milking. The milk squeezed out during the working process of the automatic milking machine is usually in a mixed state of liquid and gas. When measuring the flow of milk due to gas Interference factors, there will always be measurement errors, and the milk flow during milking will continue to change with time. The early flow is small, the middle flow is large, and the flow speed is fast. When the milk is about to be milked, the flow will decrease again. , which also affects the accuracy of the milk flow measurement

A milk production measuring device for dairy cows, comprising a lower cover, a gas phase balance tube, a milk outlet switch, a weighing sensor, and a controller, the controller is electrically connected to the weighing sensor, and the controller is based on the The real-time weight value provided by the load cell and the pre-stored upper and lower limit weight values control the opening and closing of the milk outlet switch, and record the opening times of the milk outlet switch. The total milk production of the cow in this measurement process is calculated by the number of times the milk outlet switch is turned on. The present invention adopts the combined design of the weighing sensor, the milk outlet switch and the timing unit, which realizes the weighing type flow measurement and eliminates the need for For the flow error caused by the gas mixed in the milk, the present invention also adopts a gas phase balance pipe to separate the gas in the extruded milk, so that the milk can continuously flow into the milk production measuring device of the dairy cow.
Description
technical field [0001] The invention relates to a flowmeter, in particular to a milk production measuring device for dairy cows. Background technique [0002] The automatic milking technology simulates the manual milking action through intermittent vacuum operation to realize milking. During the working process of the automatic milking machine, the milk is usually mixed with liquid and gas. Interference factors, there will always be measurement errors, and the milk flow during milking will continue to change with time. The early flow is small, the intermediate flow is large, and the flow rate is fast, and the flow will decrease when the milk is about to be milked. , which also affects the accuracy of the milk flow measurement. SUMMARY OF THE INVENTION [0003] In view of this, it is necessary to provide a milk production measuring device for dairy cows that can eliminate errors caused by gas mixed in milk. [0004] A milk production measuring device for dairy cows, compr...
