Automatic feeding device for mammals .

The invention relates to an automatic device for feeding Mammals which have a container for mixing liquid and solid feed components and for holding this liquid feed mixture contains, to which at least one line with a suction device is connected.

This automatic feeding device is characterized according to the invention by a movable suspension of the container under the action of a tension spring and by control devices for supplying the liquid feed components depending on the

respective position or the filling weight of the container.

In the accompanying drawing is an exemplary embodiment the inventive device shown, which schematically a device for feeding calves by means of milk powder and Shows water made milk.

This device contains a silo 1 for receiving the milk powder, the one in its lower, cylindrical part with a conical insert 2 is provided in order to prevent the weight of the milk powder located in the silo 1 from falling onto a distributor wheel installed on the silo floor 3 presses. This distributor wheel 3 is inside a cylindrical The opening of the silo base can be rotated around a vertical axis. Driven is this transfer wheel 3 by a motor 4 with the interposition a gearbox 5. During this rotary movement of the distributor wheel 3, a certain amount of milk powder falls into a container 6 each time, which is suspended at the end of a displaceable parallelogram 7. This parallelogram 7 is under the action of a tension spring 8, whose tensile force is selected accordingly and that on a cross member 25 hangs on two posts 26. The parallelogram 7 is pivotable about a fixed axis 9 on a support of the post 26 is stored.

The container 6 is provided with a stirring device 10 and on his Floor with several nozzles 11 for connecting hose lines equipped, which are provided at their ends with on the wall 27 of a stable or the like. Arranged suckers 13, on which the calves suck can.

The supply of water into the container 6 takes place via a line 14, a tap 15 to adjust the water flow raid a Solenoid valve 16, which rams by the shift of the Pa rallelog 7 is controlled. To do this, the parallelogram is an approach provided, which can move between two contacts 17 and 18. The water supply for the container 6 is opened by the switch 17 when the empty container is in its uppermost position, and the container 6 is interrupted by the switch 18 reaches his lowest position, i.e. when he is with a certain Amount of liquid is filled. This filling quantity for the container 6 can be set by moving the switch * 18 in relation to the Approach 19 by means of a rack 18a.

The amount of milk powder fed into the container 6 for a given The amount of water can also be changed, depending on the value on the number of animals to be fed and above all of their age.

For this purpose, the device according to the invention also contains a Control device for the supply of milk powder as a function of the displacement of the container 6. This control device consists essentially of a perforated plate 20, which with the parallelogram 7 kinematically connected via a lever 7a and displaceable in the vertical direction between two guides 21a and 21b is.

A switch 22 is arranged opposite this perforated plate 20, which sits on a slide 23, which by means of a gear 24 also is displaceable in the vertical direction. A feeler lever of the switch 22 slides on the surface of the perforated plate 20 during the vertical Displacement of this plate, each time this feeler lever hits an opening in the perforated plate 20, a pulse is sent to the drive motor 4 of the distributor wheel it 3 is given. Since this perforated plate 20 kinematically is connected to the container 6, which opposes when filling with water depending on its respective filling weight the effect of the spring 8 decreases downwards, it follows that through the distributor wheel 3 in each case as much milk powder into the container 6 is conveyed as it corresponds to the capacity of this container, since this leads along the perforated plate 20 in front of the switch 22 when it sinks.

As a result of this arrangement, the amount of milk powder placed in the container 6 is directly dependent on the amount in the container 6 Wa s e rm tight e.

Since the supply of milk powder causes a displacement of the perforated plate 20 makes necessary, it can happen that with continuous suction on the suction cups 13, the container 6 remains constantly empty and does not sink can, so that the supply of milk powder remains interrupted and the contents of the container more and more due to the ongoing water supply is diluted. However, tests have shown that the calves stop suckling as soon as the milk powder solution is not concentrated is enough. In this way, the calves themselves regulate the concentration of the milk powder solution produced in the container 6. By the way, one can also get a similar reaction from all other sow » expect animals.

However, the concentration of the milk powder solution can also take place automatically, and by varying the vertical position of the switch 22 before the perforated plate 20. Thus, for example, at a setting of this switch over the upper parts of the perforated plate 20, its sensing lever only for a short distance of the perforated plate slide , if this drops depending on the filling quantity of the container 6, so that the actuation of the switch 22 is already on *

hears before the container 6 has reached its lowest position. on in this way, a lower number of revolutions of the distributor wheel 3 and thus a lower delivery rate of milk powder are obtained in the container 6.

In a modified embodiment, the inventive .Feeding device can also be provided with a signaling device, which, for example, uses a loudspeaker to indicate feeding to the animals.

It goes without saying that the feeding device according to the invention not limited to the processing of milk powder, but rather suitable in the same way "for the production of other, liquid animal feed from liquid and solid components. This means that this device can also be used to feed or nourish all other mammals serve or as a simple drinker, the liquid level of which always remains constant due to the devices described.
