MELXIDINRIfiHTHWG ·..· j DESCRIPTION

The invention relates to a device for milking cattle, essentially comprising a walking surface with catching means, for example a grid, a group of milking cups which are connected to a common collecting hose via a milk distributor. Such milking systems are often used in stalls of any design, for example in herringbone stalls, loose stalls, carousel stalls, whereby the animal is brought to the milking parlor and guided into the correct position by grids or similar means. The milker only needs to connect the milking cups to the four teats, after which milking can begin. The milking process is often automatically terminated by a vacuum control signal, whereby the milking cups automatically detach from the teats. During the milking process, the common collecting hose lies loosely on the udder and thereby exerts an uneven load on the animal's udder, namely more on the two front collecting spaces than on the two rear ones. This means that the front collecting areas are empty sooner than the often larger rear collecting areas. Because the automatic termination of the milking process responds to the first empty collecting area, this means that the animal is not completely milked dry.

The invention aims to create a milking system in which the above-mentioned problem is solved. The device according to the invention differs in that

Walking surface 1/ onto which the animal/here a cow can be led from the free-stall stall to the milking parlor and from which it can run away again after the milking process. The animal is guided through a catching fence 2, of which three parallel bars are shown. The fence can of course have any suitable design. The milking device consists of four milking cups 3, which are connected to the common collecting hose 5 via a milk distributor 4. The collecting hose 5 leads to a collecting vessel 6. The milking cups are controlled by a vacuum hose 7. Such a milking device can be of any known type and falls outside the scope of the invention. According to the invention, a hose carrier 8 is attached, which is shown here in the form of a pivoting lever. The lever is pivotably suspended at 9 on an L-shaped support 10 which is attached to the lower beam 2 of the grille.

The free end 11 of the swivel lever 8 is provided with a bracket 12, with which the hose 5 and the vacuum hose 7 can be attached _to the swivel lever 8. The swivel lever 8 is extended past the joint 9, to which extension 13 the lower end of a traction cable 14 is attached. The traction cable is attached at the top to a pulley of a block and tackle, the other pulley 16 of which is attached to the lower end of a piston 17 of a vacuum cylinder 18. The rope 19 of the block and tackle is connected at one end to the lower end of the piston 17 and runs over the pulley 15 or pulley 16 to the milk distributor 4.

of the milking device* The cylinder 18 is connected via a connection support to the vacuum system, which also includes the vacuum hose

7. The vacuum system is not shown further, as this is considered to be generally known.

Finally, it should be mentioned* that the pivot lever 8 is provided with an eyelet 21 at a point between the joint 9 and the end 11, to which the end of a tension spring 22 is connected. The tension spring rests at the other end on the support 10 of the pivot lever 8.

The device shown above works as follows: After the cow D has been placed in the correct position near the milking device, the milker can bring the milking cups 3 to the animal's udder. He does this after the vacuum of the cylinder 18 has been removed, whereby piston 17 sinks and releases cable 19. As a result, the milking cup group 3 sinks and each of these milking cups can be connected to a teat. As piston 17 sinks, cable 14 is also released, whereby spring 22 moves the pivot lever 8 from the position shown with a dotted line in Fig. 2 to the position shown with solid lines. This raises the vacuum hose 5 or vacuum hose 7 to below a point above the walking surface 1, namely approximately in the middle under the animal D.

After the pulsating vacuum system on hose 7 has been activated, the milking process can take place, which is assumed to be known. By turning the swivel lever

8 lifts the hose 5 so far, the weight acting on the teat cup group 3 is mainly carried by the

·· i J hi Ui

nindeep zither! of the udder/ that is, from the posterior collecting chambers. Through this pulling movement

the rear collecting spaces are emptied very effectively. After the milking process has been completed by the automatic release of the teat cups 3, the vacuum can also be automatically reset at lower pressure. As a result, the piston 17 is moved upwards, taking the cable 14 with ^it ; ^when the pulling force on the cable 14 is ^released , the pivoting lever 8 is returned to the position shown in dashed lines in Fig. 2 and the teat cup group 3 is automatically raised.

The animal is then free to move away via running surface 1.

The facility is now ready for the next milking process.
The invention is not limited to the embodiment described above. The pivot lever 8 can be replaced by another hose carrier system, for example by a lifting cylinder mounted in the floor 1.
