Description

TEAT WASHING MEANS
The present invention concerns a teat washing means for washing udder teats mechanically.
Currently, washing of teats of a cow's udder is prac¬ ticed with fabric towels or in so-called two-phase washing, in which the teats are first washed with dis¬ posable towels and thereafter dried. Said washing met- hods do not always meet the requirements nowadays im¬ posed on cleanliness because the end result of the washing is not necessarily good enough every time. In particular, cleanness of the teats is of primary impor¬ tance in view of maintaining in the milk a bacterial flora which enables cheese dairies, for instance, to operate without quality risks.
In the application print EP 189 954 is disclosed an udder washing means in which a cup-like washing basin is placed around the udder and water is sprayed onto the udder. The means is, however, heavy and cumbersome to use and, in addition, clean water and dirty water become mixed in the washing process because there must be nozzles all around the basin. Hereby the same dirty water is set into rotating movement around the udder in the basin, only part thereof being removed through the removal pipe. Therefore the cleanliness of the udder after the washing is questionable.
In order to eliminate said problems, the object of the invention is to introduce a novel teat washing means with which uniformity and high standard of the teat washing result are guaranteed, as well convenient and rapid working.
Regarding the characteristic features of the invention, reference is made to the claims section. The udder teats washing means of the invention comprises a partly open washing chamber provided with a removal conduit. As taught by the invention, the open end of the chamber is constituted by a mouth aperture dimen- sioned to conform substantially to the cross section of the teat and in the proximity of which, advantageous¬ ly inside the aperture, nozzles have been provided. It is thus understood that the teats can be washed, one at a time, by pushing the teat in through the nozzle aper- ture, that is, applying the chamber around the teat, while at the same time water, or another washing liquid, is jetted against the teat, thus washing it.
Advantageously, the nozzles are also connected to a rinsing water system separate from the washing water system, whereby the teats may first be washed and subse¬ quently rinsed with separate rinsing water. It is also possible to use separate nozzles for the washing and rinsing waters.
Advantageously, the nozzles form at the open end of the chamber a ring encircling the chamber so that the teat will be becomes uniformly washed all over as it passes through the nozzle ring. Although the diameter of the nozzle ring is advantageously close to the teat diameter dimensions, the shape of the chamber itself is subject to no limitations, being determined e.g. by the shape of the body part which is being used.
In an advantageous application of the invention, the means comprises, in conjunction with the washing cham¬ ber, rotating brushes adjacent to the nozzles, these brushes as they rotate even further boosting the washing effect. The motor driving the brushes may be an electro- motor located close to them, or the brushes may be rotated e.g. by a motor mounted at a distance and with which the brushes are connected by a rotating wire. Advantageously, the washing means proper is merely an integral unit fitted with a handle and comprising the above-mentioned washing chamber, in which case to this unit are connected, by flexible tubes, a washing water tank with pump, a rinsing water tank with pump and a used water tank with pump, and a mechanical connection linking the brushes with their drive motor and an electrical connection between the control unit controll¬ ing the means and a switch disposed on the unit. Thus, the control unit is advantageously arranged, after receiving a starting signal, to run through a given programme, pumping washing water, and thereafter rinsing water, into the washing chamber, at the same time draw¬ ing off ■ used water and, during the washing process, moreover rotating the brushes in a suitable manner.
In an additional application of the invention, the chamber comprises additional nozzles with-which air can be blown on the washed and rinsed teat to dry it. It is also possible to use the same nozzles for blowing air which are used in the washing and rinsing steps.
The advantages over prior art which the invention affords include, above all, accurate, uniform and posi- tive washing of the teats, the result of the washing operation depending on a suitable programme, which can be adjusted in the control unit. Considerable saving of time in the washing process and easier work are further advantages.
The invention is described in the following in detail, reference being made to the drawing attached, wherein:- Fig. 1 presents a washing means according to the inven¬ tion, partly sectioned, Fig. 2 presents part of another washing means according to the invention, and Fig. 3 presents a washing means arrangement according to the invention in its entirety.
A washing means according to the invention, depicted in Fig. 1, comprises a cavitary washing chamber 1, which is a space that is open upwards from the unit but otherwise closed. The -means is furthermore provided with a handle 17, on which also has been mounted a switch 18 and with the aid of which it is easy to place the means under the udder of a cow and to lift it so that a teat enters the chamber. On the wall of the chamber, close to its open upper end 2, is located an annular nozzle 4, presenting a plurality of nozzle holes uniformly spaced around the chamber. The nozzle is connected both to the washing water system 3 and to the rinsing water system 7, and at the other end 5 of the chamber, at the lower end of the chamber, a removal conduit has been provided, through which the water has been arranged to escape. The chamber 1 is furthermore hinged to break open along the line 21, whereby it can be opened for cleaning whenever needed.
In Fig. 2 is presented an additional application of the means of Fig. 1, in which rotating brushes 8 have been provided in the vicinity of the nozzle 4 and below it. The brushes have been so disposed that their bristles meet in the middle of the chamber, whereby two cylin¬ drical brushes are sufficient to brush the teat uni¬ formly all over as it passes by the brushes.
In Fig. 3 is presented a washing system according to the invention in its entirety. Therein, to the washing means is connected a washing water tank 10 with pump 13, a rinsing water tank 11 with pump 14 and a used water tank 12 with pump 15. To the means is also con- nected a motor 9 to rotate the brushes. All pumps, the motor and the washing means itself are connected to a control unit 16, which is programmable to carry out the teat washing in desired manner. In addition, the unit may comprise a storage battery 11 and a battery charger 20, in which case it is not bound to a fixed location and may rather be moved as need be, e.g. along with the milking trolley.
The system of Fig. 3 operates as follows. When a person takes the washing means in his/her hand, he/she pushes it in under the udder so that one teat pushes its way into the washing chamber; and at the same time the switch 18 is pressed, whereby the motor 9 begins to rotate the brushes and the pump 13 pumps washing water from the washing water tank 10 through the nozzles onto the teat. After a preset period of time, the pump 13 stops, and possibly also the motor 9, and the pump 14 starts, whereby rinsing water from the rinsing water tank 11 is jetted through the nozzles onto the teat. As soon as the pump 13 has started, the pump 15 also begins to draw off used washing water from the bottom of the washing chamber, and this latter pump is advan¬ tageously arranged to operate somewhat longer than the rinsing water pump 14, whereby complete emptying of the chamber on conclusion of the rinsing period is ensured. The control unit 16 is advantageously provided with controls enabling the washing as well as rinsing time to be steplessly regulated; when once in this way the proper time schedule has been . empirically found, one may rest assured that the result of washing will be uniform and good always and in all circumstances.
The invention has been described in the foregoing in detail, referring to certain advantageous embodiments thereof. However, they are not restrict to the inven¬ tion, of which the various embodiments may vary within the scope of the inventive idea delimited by the claims.
