Abstract

The sensor is intended to measure temperature and electric conductivity of milk from each quarter individually during the milking process. It consists of the body of the circular section with two short sleeves with built-in probes for measurement of temperature and electric conductivity of milk, which are during the milking process permanently dipped in milk. The sensor enables to measure temperature and electric conductivity throughout the whole milking from each quarter individually. It does not require any special modifications of the milking set. The measurement by this sensor enables to select milk cows with changed state of health or damaged milk by inflammation processes.<IMAGE>

Vynález sa týká snímača na meranie teploty a elektrickej vodivosti mlieka u dojnic z jednotlivých štvrtiek vemena.The invention relates to a sensor for measuring the temperature and electrical conductivity of milk in dairy cows from individual udder quarters.

Vačšina doteraz vyvinutých snímačov na meranie teploty a vodivosti sú zabudované v rozdělovači mlieka, připadne niektoré sondy na meranie teploty sú vlepené do hadic strukových gúm. Meranie teploty v rozdělovači neposkytuje objektivně výsledky, pretože nastáva podstatné zníženie teploty vzhladom na vzdialenost medzi ceckom a rozdelovačom. Vlepené tepelné sondy do ceckových gúm na meranie teploty v mieste lepenia po určitom čase sa zhoršuje kvalita ich upevnenia z dóvodu kůrnatenia gumy a straty jej elastickosti. Riešenie snímača vodivosti z každého cecku samostatné podlá PAULA a SPECKMANA umiestneného v krátkej mliekovodnej hadici ceckovej gumy nenašlo uplatnenie v praxi z důvodu jeho nadmernej velkosti.Most of the temperature and conductivity sensors developed so far are incorporated in the milk distributor, or some temperature probes are glued into the teat rubber hoses. Measuring the temperature in the manifold does not objectively produce results because there is a substantial reduction in temperature due to the distance between the boil and the manifold. The glued thermal probes in the tumbler rubber to measure the temperature at the bonding point after a certain time deteriorate the quality of their attachment due to the rubber bending and loss of elasticity. The solution of the conductivity sensor from each teat separately according to PAUL and SPECKMAN placed in the short milk-water hose of the teat rubber has not found its application in practice due to its excessive size.

Z posledných doterajších riešení, t.j. upevnenie snímača na posledný krúžok ceckovej gumy neumožňujú spolahlivé upevnenie, pretože při napínaní ceckovej gumy může příst’ k jeho uvolneniu a zároveň je problematické aj čistenie daného snímača.Of the latest solutions, i. attaching the sensor to the last ring of the rubber band does not allow reliable mounting because the tension of the rubber band can be loosened while cleaning the sensor.

Skůr uvedené nevýhody sú odstránené snímačom zmien fyzikálnych vlastností mlieka podlá vynálezu, ktorého podstata spočívá v tom, že počas dojenia v meracej komoře snímača sú trvale ponořené vodivostná a tepelná sonda. Snímač je umiestnený v hadici ceckovej gumy pomocou krátkých nátrubkov. Elektrické signály sú vodičom vedené zo sond na zberný konektor, rýchlo upnutelný na hornom veku rozdelovača.The aforementioned disadvantages are eliminated by the sensor of changes in the physical properties of the milk according to the invention, which consists in the fact that during the milking in the measuring chamber of the sensor the conductive and heat probe are permanently immersed. The sensor is placed in the teat rubber hose with short sleeves. The electrical signals are routed from the probes to the collector connector, which can be quickly mounted on the top cover of the distributor.

Snímač sa napája na zberný’ konektor zástrčkou vedenou do konektora.The sensor is fed to the collector ’connector by plugging it into the connector.

Medzi podstatné výhody snímača patří jeho umiestnenie blízko cecku v krátkej mliekovodnej hadici ceckovej gumy, minimálně tepelné straty, velká pevnost, meranie teploty a vodivosti z každého struku samostatné, jednoduchá montáž a demontáž, malé rozměry, možnost’ signalizácie ukončenia dojenia z každej štvrťky samostatné a nezasahovanie do konštrukčných parametrov rozdelovača.Significant advantages of the sensor include its location near the drip in a short milk-water hose of the drip rubber, minimum heat loss, high strength, temperature and conductivity measurement from each teat separately, easy assembly and disassembly, small dimensions, not interfering with the design parameters of the distributor.

Na obr. 1 je schematicky znázorněný predmet vynálezu a na obr. 2 je celkový pohíad zapojenia snímača v dojacej súprave.In FIG. 1 is a schematic illustration of the invention and FIG. 2 is an overall view of the sensor wiring in the milking kit.

Snímač zmien fyzikálnych vlastností mlieka pozostáva z telesa kruhového prierezu 2, s dvorní krátkými nátrubkami 2_.The sensor of changes in the physical properties of milk consists of a body of circular cross-section 2, with yard short sleeves 2.

Vlastně teleso snímača je vyrobené z nehrdzavejúceho a nezávadného materiálu. Priečne stredom je rozdělený na dve komory, ktoré sú spojené otvorom vo vrchnej Časti snímača 2 a malým otvorom v spodnej časti snímača 4_. V meracej komoře (prívodnej) 2 sú umiestnené 2 elektrody na meranie vodivosti mlieka £ a sonda na meranie teploty mlieka 2· Meracia komora je riešená tak, že při normálnom prietoku mlieka počas dojenia sú elektrody a tepelná sonda trvale ponořené v mlieku. Při zníženom prietoku a následné po ukončení dojenia, aby sa všetko mlieko odsálo z meracej komory je na spodu malý odsávací otvor 4. Predná stená snímača je z priehladného materiálu a snímatelná, čo umožňuje po znečistění snímača ho vyčistit. Celý snímač je z nezávadného materiálu odolného voči agresívnemu prostrediu. Snímač je možné rýchlo odpojit od dojacieho zariadenia a zo zberného konektora 2· Tým ďe daná možnost rýchleho rozobratia celej časti rozdelovača.Actually, the sensor body is made of non-corrosive and harmless material. The transverse center is divided into two chambers which are connected by an opening in the upper part of the sensor 2 and a small opening in the lower part of the sensor 4. In the measuring chamber (supply) 2 there are 2 electrodes for measuring the conductivity of milk a and a probe for measuring the temperature of the milk 2. At a reduced flow rate and after milking is complete to suck all milk out of the measuring chamber, a small suction opening 4 is located at the bottom. The whole sensor is made of harmless material resistant to aggressive environment. The sensor can be quickly disconnected from the milking equipment and the collection terminal 2 · This e d option given the rapid dismantling of the whole of the distributor.

Snímač zmien fyzikálnych vlastností mlieka má nasledovný pracovný režim: Při dojení mlieko preteká daným snímačom tak, že najprv sa zhromažďuje v meracej komoře 5 a po jej naplnění vrchným otvorom vytéká cez odvádzaciu komoru 9 do rozdelovača 10. V meracej komoře sa pomocou elektrod a tepelnej sondy sa snímajú elektrické signály o kvalitě mlieka. Tře sú potom prostredníctvom elektrického vedenia napojené na merací a vyhodnocovací obvod. Snímač sa čistí samočinné pri dezinfekci! dojacej súpravy. Váčšie nečistoty, ktoré můžu vzniknut při spadnutí ceckových nástrčiek sú zadržané v snímači. Po uvolnění prednej steny sa dá snímač vyčistit.The milk change sensor has the following operating mode: When milking, the milk flows through the sensor so that it first collects in the measuring chamber 5 and after filling it through the upper opening flows through the discharge chamber 9 into the distributor 10. In the measuring chamber is electrodes and heat probe. the milk quality electrical signals are recorded. The three are then connected to the measuring and evaluation circuit by means of an electrical line. The sensor cleans automatically when disinfecting! milking kits. Any dirt that may be caused by dropping the tin plugs is retained in the sensor. The sensor can be cleaned by releasing the front panel.
