DD265750A3 - FEEDING DEVICE FOR PIGS - Google Patents

Abstract

The invention relates to a feeding device for pigs, in which the supply of animals on the principle of self-withdrawal of feed mixtures in liquid or pasty consistency from pressurized pipelines takes place. The object of the invention is to achieve a reliable portioned delivery of the liquid feed from a pressure line into the trough. According to the invention, the object is achieved by a double valve as a dispensing and portioning element, which is connected via a rod with an actuating element at the lower end of the feed downpipe.

Field of application of the invention

The invention relates to a feeding device for pigs, in which the supply of animals on the principle of Seibetentnahme of feed mixtures in liquid or pasty consistency from pressurized pipelines takes place.

Characteristic of the known technical solutions

In particular, in pig husbandry various self-withdrawal devices for liquid feed are known, wherein the feed from central Rohrlettungar: or from storage containers of the individual removal device is supplied.

The feed is removed by the animal in each case by the actuation of a dosing or Absperrelemonies in the form of spring, pressure or weight-loaded valves, slide clamps or similar closure elements.

These devices, e.g. according to GB-PS 1400736, DE-OS 1507131 or DD-PS 84513, however, due to blockages, sedimentation and deposits of Futterbestandtellen, gluing the sliding and sealing surfaces or by mechanical closure of the dispensing mechanisms do not expect sufficient reliability.

Another major shortcoming of the known solutions is the uncontrolled food spillage on actuation of the dispensing mechanisms, which leads to Fu et et waste through the animals to trough overfilling.

Also, the adjustable design of the actuating mechanisms, e.g. the stroke length for a cone valve to DE-GM 8033026, has created no remedy in this regard.

Some of the known Futterabgabeelemente are also by a complicated structure and therefore a high

Production costs marked. The high loads In stable operation, these facilities do not withstand.

A portion-wise feed delivery is realized with the feeding devices according to DE-AS 2225967 and DD-PS 223621. In the former solution, however, the delivery of the feed is automatically gestusrt by the pressure in the feed tube, so that an animal-dependent and thus needs-based food supply is no longer given. Both solutions have technically complicated) and error-prone Portionierungsmechanlsmen. Due to the functional deficiencies, there is a reduced or excessive feed delivery.

The device according to DD-PS 223621 has a certain Schwergänglgkeit, so that it is only suitable for animals from a certain biomass. Due to the inertia of the system the Portionierungsfählgkeit is impaired.

Object of the invention

It is the object of the invention to reduce in the self-removal of Flüseiyfutter from pressure-loaded pipelines, dio feed losses due to uncontrolled feed leakage, to reduce the technical complexity of the Portionierungsmechanlsmus and to improve its reliability and to obtain over a long period of use.

-2- 265 Explanation of the essence of the invention

The invention is based on the object, a Selbstfütterungeeinrichtung for pigs with little technical effort

and high reliability, which, upon actuation of an element by the animal, produces a portioned delivery of the product

Liquid feeds eus a pressure line in a trough with constipation-resistant function guaranteed. According to the invention the object is achieved in that the valve to be actuated by the animal within a downpipe than Double valve preferably as Doppeikegelventil, consisting of a double cone as a valve body and a center A suitable valve ring is executed and thus acts as a discharging and portioning element

animal valve body is connected to an actuator at the lower end of the Futterfallrohres.

According to another feature of the invention, the maintenance element is a ring, depending on the type of feed trough

odor as Ringsegrnent, preferably folded from round material, so that it is accessible at all eating places for the animals.

The connection between linkage and actuator is made by a cross rail, for in the Futterfallrohr

corresponding slots are arranged opposite one another.

To guide the actuating element and the linkage connected to it are preferably two on Futterfallrohr Sleeves attached, the vertike! freely movable Dormt record, which on the actuator or d> r cross rail

are attached.

If the actuator for the purpose of Futterentnahrr e raised by the animals, the Bicone is over the Linkage actuated. Initially lifts the upper Kegul of the valve body from the valve ring, so that feed from the Delivery pipe can flow into the Futterfallrohr. Oa the lower cone at the same direction of movement the valve immediately

closes again, a portioning feed delivery is achieved. By the weight of the whole

Actuating mechanism as well as by the present in the delivery pipe pressure is the discharge · and Portioning element w! K gate closed by the upper cone as soon as the actuating element through the animals

released wiru.

Compared to known conical valves, the upper and lower valve seats of the valve ring are sharp-edged, whereby Fu animal ingredients squeezed or cut off, so that a secure closure of the double cone valve achieved exemplary The invention will be explained in more detail below with reference to a Ausführungsbeispielispiele. In the accompanying drawing is

a Futtorabgabeelement represented via a feeding trough.

Under an outlet opening of the feed tube 1 by means of screw 2, the clamping shell 3 is fixed, the nozzle 4 the Futterfallrohr 10 with the valve ring 5 and the valve body receives β. A linkage 7 in the chuck tube 10 provides the connection between the valve body β and the actuator 8 on Outlet of Futterfallrohrrohr 10 via a cross rail 9 ago, for the free movement of two opposing slots 13 in Feed tube 10 are provided. To guide the actuating element 8 and the linkage 7 are on Futterfailrohr 10th

two sleeves 11 attached, which receive the pins 8 attached to the actuator 8. Considering the physiological conditions of the pigs and the trough, the actuator 8 is made as a ring and round material.

If this element is actuated by the animals, then the double cone β is raised via the linkage 7. The upper cone opens

while the valve, so that the flow funnel can flow into the Futterfsllrohr 10. In the same stroke phase, the valve is closed again by the lower Kegol, so that only a defined portion of feed can escape. As soon as the ring element 8 is released by the animals, the entire actuating mechanism drops into its position due to its own weight

Starting position back, so that the valve closure takes place again through the upper cone. This is again a limited Feed portion delivered in the downpipe 10. In this way it is ensured that the valve is always open only for a short time and only a small amount of feed in

got the trough. By the stroke limitation of the double cone 6 on a door limited the Futerabgabe Mlndeii '-' ß becomes

ensured that the animals do not hold the double cone valve in the open state and an overflow of the trough " ntritt.

The limitation of feed withdrawal by the animals to certain feeding times can be controlled by a time control of the animals Conveying organs or by a mechanical locking of the actuating element done. Due to the sharp-edged design of the valve seats in the valve ring 5 a secure closure of Doppelkegp valves is achieved

since feed ingredients are squeezed or cut off, which could otherwise lead to clogging or jamming of the valve. For pre-deposition of deposits above the double cone valve, this is flush with the lower edge of the

Delivery pipe 1 is arranged so that an unobstructed flow to the valve is constantly ensured.
