DE1026568B - Control device for the water supply to the cattle tank - Google Patents

Description

GERMAN

The invention relates to a control device for the water supply to cattle drinking bowls. The control device should enable the cattle to drink at any time in the barn. She should also Also suitable for drinking basins set up outdoors. For this purpose, control devices are already with from Animal moving and a sealing body against the inlet pipe pressing valve known. So is at of such a known regulating device, the water flow through a valve lever operated by the flap controlled, which in turn presses a sealing body against the opening of the water supply pipe. The lifting of this valve body takes place against the force of a specially provided spring, which at the same time holds the flap in the normal closed position. The known regulating device avoids wasting water and always provides the animal with fresh water, but consists of several parts, which are all exposed to the weather when the drinking basins are set up outdoors and therefore wear out quickly and fail. This is especially true for the feather exposed to moisture, which after a short time Time corroded.

The invention avoids these difficulties in that the sealing body consists of a cylindrical There is a role that is rotatably mounted with a horizontal axis in the flap that it is in the rest position the supply pipe closes and the flap resiliently holds in the closed position when the flap is depressed on the other hand, it is elastically deformed by the animal and releases the flow of water. The deformation takes place under the lever pressure of the flap and releases a gap at the seat of the roller in the water supply pipe. As soon When the pressure on the flap ceases, the flap is returned to its original cylindrical shape The receding roll is pushed back into the closed position and the water supply is shut off. At the When the valve is opened, the roller does not lift off the valve, but merely rotates and deforms above the valve.

The control device according to the invention consists practically only of two moving parts, which can be made from non-metallic materials and are therefore not exposed to corrosion. With the Role according to the invention can fulfill three functions, namely regulate the water supply, the valve body Press elastically onto the valve body and push the basin flap through after the water has been withdrawn return the animal elastically to the closed position. No special valve or balancing springs are required for this for the pelvic valve.

The sealing body seat and the adjoining water inlet pipe have an expediently cylindrical cross section for a uniformly sealing seat. Under the regulating device for the water supply

for claims 1 and 2

Antonio Bertazzoni, Guastalla (Italy),
has been named as the inventor

Pendulum flap can be pivoted in a swivel rod, which when the flap is unintentionally lifted hooks behind a stop in the drinking bowl and prevents the flap from swiveling up.

The drawing shows an embodiment of the invention. It shows

1 shows a side view of the device attached to a basin in the closed position; the Dashed lines show the position of the moving parts when the water inlet is actuated;

Fig. 2 shows the control device completely swiveled up;

Fig. 3 shows a mechanical lock against unintentional pivoting up.

At the rear end of the basin 1, a hollow element 2 is screwed in the longitudinal direction and connected at its lower end to the water pipe. The upper end of this part 2 forms a support for the roller 3, which is made of sufficiently elastic material, ζ. B. rubber (Para), and is freely rotatable about the horizontal axis 4. The axle 4 is attached to a lever where it acts as the weight (resistance). The lever rotates around pivot point 5; the force is provided by the pressure exerted on the part 6 by the animal's nose.

The way it works is as follows: In the rest position, the weight of the calculated weight holds Lever the roller 3 against the support, for. B. Edge 7, the part 2 is pressed and thus ensures inevitable

Tightness. To drink, the animal presses on the lever 6, which is shaped accordingly, e.g. B. as one Flap that gives the animal's nose a certain area. The pressure with the nose lowers the lever. These Movement is communicated to the axis 4, which is preferably not aligned for the purpose of better effectiveness with power lever and pivot point and so squeezes the roller against the edge 7 of the part 2 and transversely emotional. As a result of this movement, the side of the roller 3 which is located after the actual basin deviates from the corresponding part of the support and opens a slot through which the water flows freely. When the animal stops pushing the lever, the roller takes on its own elasticity returns to its original shape, pushes the lever back into its rest position and closes at the same time the water inlet.

The invention also offers the possibility of using the lever, which can be pivoted upwards by more than 90 °, to be lifted completely so that the inside of the pool is completely accessible for cleaning and the roller 3, can be easily replaced if necessary. Foreign bodies can also be removed from the water pipe in this way remove. The inside of the roller 3 has a concentric small tube that receives the axis 4. This one by any two pens, e.g. B. split pins, it is sufficient to pull out the axis to the role can be changed quickly and easily.

To prevent the animal from lifting the nasal valve or from any excess water pressure is thrown up, a pivot rod 8 attached under the flap engages under a stop 9. If the nasal valve has to be loosened, the swivel rod can be pushed down after the The flap can be removed from the stop 9. Without exceeding the scope of the invention, the invention can be subjected to extensive changes in its construction details.

Claims (3)

Patent claims: 1. Control device for the water supply to cattle drinking basins with one moved by the animal and one Sealing body against the inlet pipe pressing flap, characterized in that the sealing body consists of a cylindrical roller (3) made of elastic material with a horizontal axis (4) is rotatably mounted on the flap (6) so that it shuts off the supply pipe in the rest position and resiliently holds the flap in the closed position upon depression of the flap by the animal on the other hand elastically deformed and the water inflow releases. 2. Control device according to claim 1, characterized in that the sealing body seat (7) and the adjoining water inlet pipe (2) have a cylindrical cross-section. 3. Control device according to claims 1 and 2, characterized in that under the Pendulum flap (6) a pivot rod (8) is articulated, which when the unintentional lifting of the The flap hooks behind a stop (9) in the drinking basin and prevents the flap from swiveling up.
