Description

Milk flow meter

(1) technical field:

The utility model relates to a kind of mechanical device, especially a kind of milk flow meter.

(2) background technology:

At present, the type of flowmeter has a lot, as canal formula flowmeter, electromagnetic flowmeter, target type meter, vortex street, turbine | flow integrator positive displacement (elliptic gear, waist wheel, rotary-piston, scraper plate, screw rod etc.) flowmeter, Doppler ultrasonic flow meter, Coriolis flowmeter etc., but all require measured fluid flow even in their principle of work and the application in liquid flow measurement thereof, liquid is full of measures the cross section.Because to milk is to carry out in the negative pressure process, gas, milk mix, and have a large amount of irregular bubbles to be mixed in wherein, above-mentioned these flowmeters all can't be accurately the output of milk of automatic gauge milk cow in real time.Now, the flowmeter of the output of milk of some real-time automatic gauge milk cows is arranged abroad, easily do not nuzzled up, cover electrode surface, make the output signal fluctuation by the bubble that may exist in the milk but all solve potential electrode; Or the apolegamy of electrode material and measured medium is not good at, and produces chemical actions such as passivation or oxidation, and electrode surface forms dielectric film, and galvanochemistry and polarization phenomena etc., all hinders normal measuring reliability and accuracy.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of milk flow meter, and it can solve the problem that prior art exists, and measures milk production of cow accurately, and can measure the milk conductivity simultaneously.

The technical solution of the utility model: a kind of milk flow meter, it is characterized in that it is by energy threshold and metered body are constituted, the output terminal of energy threshold is connected with the input end of metered body, said metered body comprises loam cake, place metered body in the loam cake advance milk mouthful, counting valve, in the solenoid valve of air pressure between diaphragm and the film seat of film seat, control counting valve of diaphragm, the counting valve of intermediate receptacle, the lower cover of electrode, the milk outlet that places the metered body in the lower cover, counting valve is arranged and places the interior tracheae of film seat of counting valve; Said counting valve input end is connected with the output terminal that advances the milk mouth of metered body, its output terminal is connected with the input end of the milk outlet of metered body, there is the intermediate receptacle of electrode to be connected with the counting valve in said according to electrode, the output terminal of the milk outlet of said metered body is connected with the diaphragm of counting valve, said solenoid valve is connected with the input end of tracheae in the film seat that places the counting valve, and the output terminal of the tracheae in the said film seat that places the counting valve is connected with the diaphragm of counting valve.

Diaphragm, the film seat that makes energy threshold, the control diaphragm that makes energy threshold and film seat between air pressure solenoid valve and place tracheae formation in the film seat that makes energy threshold; The said output terminal that advances milk mouthful that makes energy threshold is with the diaphragm that makes energy threshold and the input end of the milk outlet of energy threshold is connected; The said output terminal of the milk outlet of energy threshold that makes is connected with the input end that advances the milk mouth of metered body; Said solenoid valve with place make energy threshold the film seat in the tracheae input end be connected; The said output terminal of the tracheae in the film seat that makes energy threshold that places is connected with the diaphragm that makes energy threshold.

Method of work of the present utility model is: when system begins to milk, make the vacuum solenoid energising of energy threshold that source of the gas is become vacuum pressure by atmospheric pressure, it is recessed to enable valve film, energy threshold is opened,, flowed out by milk outlet by advancing milk mouthful inflow milk, flow to the jigger milk inlet, this moment, jigger counting valve film projection was an atmospheric pressure in the film seat, and the jigger end opening closes to be finished.When milk constantly flows in the jigger, the milk liquid level rises steadily, when liquid level arrives when opening glass electrode height, because milk makes out current lead-through between glass electrode and the public electrode, system gives the solenoid valve power on signal of counting valve, solenoid valve action (conducting vacuum, disconnect with atmosphere), diaphragm is upper and lower all to be in vacuum and not to have pressure differential, and diaphragm is recessed, and the counting valve is opened, milk is imported milk flowing pipe road (promptly being flowed out by the milk outlet), the solenoid valve outage, the diaphragm projection, system log (SYSLOG) leaves cup once.Reach out cup simultaneously at the milk liquid level, record conductivity.The circulation said process has all squeezed to milk, and the output of milk is each round-robin accumulative total numerical value; System stops to milk, and energy threshold cuts out, the end of milking of this ox.

Superiority of the present utility model is: 1. measuring accuracy height and good reliability; 2. measure milk output the time, guarantee the quality of milk by the conductivity of monitoring milk, and learn the health status of milk cow.
