Definitions

  • the invention relates to the detection of the milk yield of cows during milking with the aid of a milking device which sucks the milk from each individual animal and conveys it to a collecting hardener, the amount of milk extracted being measured continuously during milking.
  • the invention is based on the flow rate measurement and it is the object of the invention to provide a method or a device which enables the farmer to determine the values of interest to him about the milk delivery of each individual animal with simple and accurate accuracy Above all, to record it in a reliable manner, without influencing the milking process as such in any way and in particular delaying it. It should also be ensured, if possible, that the measured values are obtained in a form that largely facilitates their recording and, if necessary, later evaluation.
  • This object is achieved according to the invention in a method of the type mentioned at the outset for determining the milk yield of cows during milking with kilfe of a suction milking device, in which the amount of milk sucked out from each individual animal is measured, in that after the milk has been sucked off a separation of the admixed air and possibly occurring foam is carried out and the milk is fed at a substantially constant pressure to a calibrated opening or line, the flow of which at this pressure is during the Milking the maximum amount of milk to be expected per unit time means that the flow through this opening or line is interrupted and the milk is collected when the inflow falls below the maximum flow rate and the pressure exceeds a predetermined fluctuation range, and that the flow times are recorded and added up .
  • the pressure driving the milk through the calibrated opening can be achieved by accumulating the milk to a given level of accumulation.
  • the level of the pent-up milk can be kept constant within predetermined limits by regulating the outflow.
  • the flow times can then, for example, be displayed on a display device which can be calibrated for quantities.
  • the invention further provides a device for determining the milk yield of cows during milking with the aid of a suction milking device, in particular for carrying out the method described above, in which seen in the suction line leading to each cow in the flow direction before it flows into the to the collecting tank leading line is connected a collecting container that collects the conveyed milk-air mixture, which is connected to the collecting line on the one hand via a negative pressure line opening at its top or in its area and on the other hand via a calibrated outlet line or opening connected to its bottom , which can be opened and closed by a control valve, the control of which is carried out by means of the receptacle associated with the elements responsive to the liquid level in the receptacle, via which the liquid level in the sense of keeping a predetermined level constant with a r predetermined fluctuation range is controllable, and include the opening times of the valve summarize and sum up.
  • a solenoid valve can be provided to open and close the outlet opening or line, and an electronic timepiece measuring its opening times can be connected in parallel with the solenoid valve, which has a summing device for the measured opening times and preferably has a display device for the measured and totaled times is calibrated in flow rates,
  • the devices which detect the liquid level in the collecting container can include electrodes which protrude through the side container wall or from above into the collecting container. Instead, however, a float can also be arranged in the collecting container, which acts on switches, in particular microswitches, in the control circuit of the solenoid valve during its upward and downward movement in the collecting container.
  • Fig. 1 shows an arrangement that can also be retrofitted with existing suction milking systems without difficulty
  • Fig. 2 shows a modification of the embodiment
  • a conventional milking device is assumed.
  • the milk of the animal to be tested is sucked in together with air via line 11. It would normally be conveyed in this form into the collecting line 12 and further into the collecting container.
  • the milk is from a collecting container 13 in which the line 11 is guided.
  • the collecting container 13 has a conical bottom which merges into an outlet line 14.
  • a solenoid valve 15 is arranged shortly before it flows into the collecting line 12.
  • a further pipe 16 is connected, which forwards the negative pressure in the collecting line 12 via the collecting container 13 to the suction line 11.
  • milk mixed with air flows through the line 11, possibly also mixed with foam, into the collecting container 13.
  • air and milk are separated from one another, with any foam that may be deposited on the milk.
  • the milk initially rises in the container 13 according to the inflow range until the liquid level reaches one of the two electrodes 17, 19.
  • This electrode 17, which is insulated through the wall of the container 13, is connected to a control and display unit 20.
  • the electrode 19 As soon as the liquid in the collecting container reaches the electrode 19, the control device 20 can respond to the solenoid valve 15, the winding 151 is excited and the valve 15 opens.
  • the liquid level in the collecting container 13 cannot rise further because the diameter of the outlet line 14 is dimensioned so large that the flow through the line 14 is greater at the liquid height determined by the electrode 19. than the maximum amount of milk to be expected that can flow in via line 11 per unit of time.
  • the liquid level in the container 13 will drop after opening the valve 15.
  • the valve 15 is closed via the control device 20.
  • the opening time is recorded and saved. It can also be continuously displayed on the display scale 201.
  • the process described above is repeated, i.e. the milk level in the collecting container 13 rises again until the electrode 19 is reached.
  • the then opening solenoid valve drains the milk collected until the lower level at electrode 17 is reached.
  • the solenoid valve closes and the opening time is added to the one already displayed and so on. It should also be mentioned that it is expedient to make the height difference between the electrodes 17 and 19 and the calibrated part of the line 14 in the vicinity of the valve 15 as large as possible. Changes in the milk level in the collecting container 13 are then taken into account as a percentage in the measurement.
  • the modification of the device according to the invention according to FIG. 1 shown in FIG. 2 relates only to the collecting container 23 and the scanning elements for the liquid level assigned to it.
  • the remaining parts correspond to the parts of Fig. 1 and are therefore provided with the same reference numerals.
  • the modified embodiment should be of particular advantage in cases where the aim is to eliminate the influence of foam on the measurement result as far as possible.
  • two microswitches 27 and 29 are arranged, which take over the function of the electrodes 17 and 19 of FIG. 1 and are connected to the control device 20 via control lines 30.
  • the mode of operation of the device corresponds to that of the device according to FIG. 1.

Abstract

Un procede et un dispositif pour determiner le rendement laitier des vaches durant la traite utilisent un dispositif de traite par 2 aspiration. La quantite de lait aspire de chaque animal est ainsi continuellement mesuree en introduisant le lait, apres elimination de l'air qui y est melange, sous une pression pratiquement constante dans un conduit calibre dont le debit sous cette pression correspond a quantite maximale de lait produite par unite de temps durant la traite. Lorsque l'afflux de lait est inferieur au debit maximum et/ou lorsque la pression depasse un intervalle de variation donne, l'ecoulement a travers ce conduit est interrompu, le lait produit est accumule et les temps d'ecoulement a travers le conduit calibre sont additionnes. La pression determinante pour l'ecoulement est obtenue en retenant le lait jusqu'a un niveau d'accumulation maintenu constant, a l'interieur de limites predeterminees, par exemple en reglant l'ecoulement, les temps d'ecoulement pouvant etre affiches sous forme de debits. Dans un dispositif particulier pour la mise en oeuvre d'un tel procede on utilise un dispositif usuel de traite par aspiration dans lequel on connecte un recipient de reception (13) au tuyau d'aspiration (11) avant son embouchure dans le conduit collecteur (12). Le recipient de reception (13) est relie au conduit collecteur par l'intermediaire de deux tuyaux (14, 16) dont l'un, sous depression, aboutit a la partie superieure du recipient de reception et dont l'autre est un conduit d'ecoulement de sortie (14) relie au fond du recipient, qui peut etre ouvert ou ferme en fonction du niveau de liquide dans le recipient (13) et qui coopere avec un appareil pour le calcul et l'affichage des temps d'ecoulement.
