"ΕΤΙΜΕΝ WASHING MACHINE - SPRING FOR SPRING

The invention relates to a puller washing device for machine washing of udder pullers.

5 At present, in barns, cows' udder pulls are washed with a cloth or so-called as a two-stage wash, in which the pullers are first washed and then dried with disposable towels. However, such washing methods do not always meet the current purity requirements, 10 because the washing result may not be good enough every time. In particular, the purity of the pullers is essential to keep the bacterial population of the milk in such a way that, for example, cheese dairies can operate without quality risks.

EP 189 954 discloses a udder washing device in which a cup-shaped sink is placed around the udders and water is sprayed onto the udders. However, the appliance is heavy and clumsy to use and in addition, when washing, clean water and dirt mix, because 20 nozzles must be in the basin everywhere.

Thus, the same dirt water circulates in the basin around the udder only when part of the outlet pipe leaves. Thus, the cleanliness of the udder after washing is questionable.

In order to eliminate these problems, it is an object of the invention to provide a new type of puller washing device. which guarantees the uniformity and high quality of the pulling result of the pulls, as well as the lightness and speed of the work.

With regard to the features characteristic of the invention, reference is made to the claims.

The udder puller washing device according to the invention comprises a washing chamber with partially open nozzles and outlet ducts. According to the invention, the nozzles form a ring at the open end of the chamber, the diameter of which corresponds to the Dimen-35 seats of the puller, so that the washing device can be pushed around the puller. In this case, the pulling of the puller takes place by pushing the puller in from the mouth opening, i.e. the chamber around the puller, the puller is evenly washed throughout as it passes through the nozzle ring. Although the nozzle ring is preferably close in diameter to the dimensions of the diameter of the puller, the shape of the chamber itself is free depending on, for example, the shape of the body used.

In a preferred embodiment of the invention, the device, in connection with the washing chamber, in the vicinity of the nozzles comprises rotating brushes which, as they rotate, further increase the washing power. The motor of the brushes may be an electric motor in their vicinity or the brushes may be rotated, for example, by a distance motor to which the brushes are connected by a rotating wire.

Preferably, the laundry itself has only a piece with a handle with a cm. a washing chamber, in which a washing water tank with pumps, a rinsing water tank with pumps and a dirt water tank with pumps and a mechanical connection between the brushes and the motor rotating them and an electrical connection between the control unit controlling the device and the circuit breaker in the body are connected to this body. Thus, preferably, the control unit is arranged according to a certain program after receiving the output signal to pump the washing water and then the rinsing water into the washing chamber while sucking out the used water and during the washing further rotating the brushes in a suitable manner.

In a further embodiment of the invention, the chamber comprises nozzles by means of which air can be blown into the washed and rinsed puller to dry it. It is also possible to use the same 20 nozzles for air blowing as are used for washing and rinsing.

The advantage of the invention compared to the prior art is, above all, the accuracy, smoothness and certainty of the washing of the pulls, the washing result depending on a suitable program which is adjustable for the control device. Likewise, the advantage 25 is a considerable acceleration and lightening of the washing operation.

The invention will now be described in detail with reference to the accompanying drawing, in which Figure 1 shows a washing device according to the invention in partial section, Figure 2 shows a part of another washing device according to the invention, and Figure 3 shows a washing device arrangement according to the invention.

One of the washing devices 10 according to the invention shown in Figure 1 comprises a hollow pre-chamber 1, which is an open but otherwise closed space upwards from the body of the device. The device also has a handle 17, which also houses a switch 18, by means of which the device can be easily placed under the udder of the cow and can be lifted so that the puller protrudes into the chamber. In the vicinity of the open upper end 2 of the chamber, in the wall of the chamber there is an annular nozzle 4 with several nozzle holes evenly around the chamber. The nozzle is connected to both the washing water network 3 and the rinsing water network 7 and at the other end 5 of the chamber 20, the lower end of the chamber has an outlet passage from which the water is arranged to exit. The chamber 1 is further articulated along the line 21 so that it can be opened and cleaned whenever necessary.

Figure 2 shows a further embodiment of the device of Figure 1, in which there are rotating brushes 8 below it in the vicinity of the nozzle 4. The brushes are arranged so that their bristles meet each other in the middle of the chamber, so that two cylindrical brushes are sufficient to brush the puller evenly on each side. past.

Figure 3 shows a washing system according to the invention in its entirety. In it, a washing water tank 10 with pumps 13, a rinsing water tank 11 with pumps 14 and a sewage tank 35 12 with pumps 15 are connected to the washing device. Similarly, a motor 9 is connected to the device for rotating the brushes. All pumps, the motor and the washing machine itself are connected to the control unit 16.

which is programmable to perform the pull of the puller as desired. In addition, the unit may include a battery 11 and a charger 20, in which case it is not tied to a fixed place but can be transported as needed 5, e.g. with a milking trolley.

The system according to Figure i operates as follows. When the washing device is taken in hand, it is pushed under the udder so that the puller pushes into the washing chamber and at the same time is pressed from the switch 18, whereby the motor 9 starts 10 to rotate the brushes and the pump 13 pumps washing water from the washing water tank 10 After the set time, the pump .13 stops, possibly also the motor 9 and the pump 14 start, whereby the rinsing water is sprayed from the rinsing water tank 11 through the nozzles into the pull-15. As soon as the pump 13 is started, the pump 15 also starts to suck out the used washing water from the bottom of the washing chamber and is preferably arranged to operate a little longer than the rinsing water pump 14, thus ensuring that the chamber is emptied of water at the end of the rinsing period. The control-20 unit 16 preferably has controllers with which both the washing and rinsing time can be infinitely adjusted, and thus, after finding suitable times, an experiential path can be assured that the washing result is always and in all conditions smooth and good.

The invention has been described in detail above with reference to some preferred embodiments thereof. However, they do not limit the invention, the different applications of which may vary within the scope of the inventive idea defined by the claims.
