Abstract: Animal drinkers of an activation unit provided with two arms engaging respective valve pin in an axially oriented manner when pivoting an activator. This reduces wear and leads to a longer service life of the drinker valve. The respective arm can moreover have a channel through which the water exits the drinker valve and can be fed in a targeted manner to the activator to ensure that all of the water exiting the drinker valve makes its way into the water collection tray.

Abstract: An improved, self-balancing water distribution system uses siphon characteristics to maintain negative pressure within the water system and to enable distribution of water to one or more distribution points, such as drinker lines with drinker nipples, at a controlled pressure, for consumption by poultry. The system includes water conduit connected to and configured to distribute water from a water supply reservoir to the one or more distribution points. The water level of the water supply reservoir is used to control the water pressure within the system. A vacuum apparatus is connected to the water conduit to remove entrapped air within the system to help maintain negative pressure within the conduit and throughout the system.

Abstract: Animal watering stations having a liquid piping system including watering lines, a supply line, and a return line. The supply line supplying liquid simultaneous to all watering lines and the return line returning of liquid to a liquid reservoir. In this way, a circulation of the liquid can be realized in at least parts of the liquid piping system and on the other hand the parallel fluidic circuit of the watering lines enables an easy adapting of the liquid pressure at the drinking valves.

Abstract: Animal drinkers for beaked animals often have drinker valves (12) which are to be opened by activation units (13). In order for the respective drinker valve (12) to be opened, an elongate activation means (29) of the activation unit (13) is pivoted by the beaked animals. Conventional drinker valves of this type have above all the disadvantage that the respective valve pin (16) of the drinker valve (12) is always tilted in the same direction by the activation unit (13). This leads to unilateral wear and therefore to the respective drinker valve (12) being worn out in a rapid manner. The invention provides that the activation means (29) of the activation unit (13) is provided with at least one arm (30, 31). On account of said arm (30, 31) the respective valve pin (16) is able to be lifted in an axially oriented manner when pivoting the activation means (29). This reduces wear and leads to a longer service life of the drinker valve (12).

Abstract: Animal drinking troughs have pressure reducers for reducing the higher pressure of the liquid supply to a low liquid pressure for supplying the animal drinking troughs. For various reasons, it is desired to change the reduced pressure. This takes place by adjustment of the pressure reducers. It is known to undertake such an adjustment with compressed air. This requires a separate compressed air source and a corresponding pipe system. The invention makes provision to adjust the pressure reducer hydraulically by means of the higher pressure of the liquid of the liquid supply. The energy required for adjusting the pressure reducers thereby provides the liquid pressure of the liquid supply. As a result, the pressure reducers according to the invention operate autonomously. A separate energy source for adjusting the pressure reducers is not required.

Abstract: An actuating means (25) for an animal drinker, the actuating means configured in such a way that the valve pin (14) is liftable by the actuating means (25) in order to open the drinking valve (12), preferably on a rectilinear longitudinal center axis (19) of the valve pin (14). In this way, one-sided wearing down of the drinking valve (12), in particular of the valve pin (14) and/or of a sealing surface (17) of the housing (13), is avoided. As a result, the useful life of the drinking valve (12) is extended.

Abstract: A method for cleaning a conveyor for agricultural products, such as eggs, and a conveyor for agricultural products, in which contaminants that adhere firmly to the conveyor are removed by the use of an ultrasonic cleaning bath into which a section of the conveyor is dipped with the aid of a deflecting unit. During the normal revolution of the conveyor chain, cleaning of the conveyor chain is carried out even during running operation of the conveying system by means of ultrasound and suitable cleaning agent. A conveyor chain having a multiplicity of rods that are connected to one another via chain links is transported in individual conveying segments of the conveyor. Lying on the conveyor chain, the agricultural products are transported. Deposits of contaminants onto the conveyor unavoidably occur during operation, such as, in particular, as a result of litter or feathers.

Abstract: An animal drinker allowing for the circulation of the water in the animal drinker. To this end, the animal drinker has two parallel pipe strings (23, 24) that form a water circuit ensuring a constant movement of water, namely that water flows continuously through the pipe strings (23, 24) even when no water has been removed at the drinking valves (20) over an extended period of time.

Abstract: Special conveying systems are used within a production plant in order to transport agricultural products such as, in particular, eggs. Here, a conveyor chain 14 having a multiplicity of rods 42 which are connected to one another via chain links 44 is transported in individual conveying segments 12 of the conveyor 10. Lying on the conveyor chain 14, the products, in particular the eggs, are transported. Deposits of contaminants unavoidably occur during operation, such as, in particular, as a result of litter or feathers. Contaminants which adhere only loosely can be removed in a simple way, for example, by suitable strippers. It is the object of the invention to also eliminate contaminants which adhere firmly and as far as possible to also minimize the number of microorganisms. This is achieved by the use of an ultrasonic cleaning bath 30, into which a section of the conveyor 10 is dipped with the aid of a deflecting unit 16.

Abstract: Drinking troughs for in particular poultry feature drinking valves arranged at regular intervals along a water supply line, with each drinking valve being assigned a water-collecting bowl (14). The water-collecting bowls (14) are usually made of plastic. The water-collecting bowls (14) are cleaned with agents that contain aggressive substances, which are capable of damaging the plastic of the water-collecting bowls (14). The invention is a water-collecting bowls (14) with a respective insert (17) made of a resistant material, thus making the water-collecting bowl (14) resistant to aggressive liquids, in particular cleansing agents.

Abstract: Known drinking troughs with drinking valves (21), which are assigned to a water-supply line (20), and water-collecting bowls (24) assigned to said drinking valves are problematic when it comes to supplying young chicks automatically with water. Known drinking troughs have proven unsuitable for young turkey chicks. The invention proposes a drinking trough which is also suitable for young turkey chicks. This drinking trough is distinguished in that valve pins for opening the drinking valves (21) are assigned elongate, tubular actuating levers (25). The actuating levers (25) facilitate the opening of the drinking valves (21). Moreover, by way of the tubular actuating levers (25) extending into the water-collecting bowls (24), the water passing out of the drinking valves (21) is directed specifically into he water-collecting bowls (24), as a result of which splashing of water is avoided.
