DE20312888U1 - Water trough for piglets has a tilting mounting for emptying and with a vertical feed water pipe - Google Patents

Abstract

A water trough for piglet rearing is hinged about a bottom front axis to tilt up for emptying. The rear end of the trough is connected to a vertical water feed pipe (34), from an upper mounted membrane valve (46). In the normal position the trough is kept filled by the automatic watering system. For cleaning the trough is tilted up by pulling the water pipe. As the trough is tilted up it opens the water flow to add to the cleaning effect.

Description

The subject matter of the invention is the tipping trough according to claim 1.

While immobile troughs with an outlet valve that has to be opened using an actuating tongue or rod overwhelm the weak piglets and are difficult to clean, the tipping trough according to the invention with a membrane-operated shut-off valve ensures automatic filling of the empty or only partially filled trough up to the lower edge of the water supply pipe, the lower end of which penetrates into the trough at an adjustable height; and this enables the trough to be swiveled to empty it by pulling up the end that is located away from the sloping transverse wall using the pipe after it has been released, whereby this pipe is moved vertically and at the same time moved horizontally. Advantageously, when the tipping trough is deflected from the horizontal, water starts to flow out of the lower end of the pipe, so that the trough self-cleans, which can be ended at any time by swiveling the trough back to the horizontal and then filling the trough.

The tipping trough according to claim 2 has the particular advantage that the chosen axis arrangement contributes to the largest possible pivoting lever arm.

The tipping trough according to claim 3 has a modified cuboid shape in the form of a household chute. The tipping trough according to claim 4 also has the advantage that the selected rod bearing does not disturb the interior of the trough and does not require any separate additional parts on the trough. The tipping trough according to claim 5 has a particularly simple locking mechanism for the lower end of the pipe. Finally, in the tipping trough according to claim 6, the suspension and the fixing of the upper end of the pipe are easy to handle and protected against the consequences of involuntary piglet attacks on the pipe.

In the following, the invention is explained in detail with reference to a preferred embodiment of the tipping trough according to the invention, which is shown by way of example in the accompanying drawing.

The only figure in the drawing shows a partially schematized perspective view of the embodiment from the front at a horizontal distance from a pen wall of a piglet pen, which is to be imagined to be behind the plane of the drawing; on the one hand (left) in the operating state and on the other hand (right) in the emptying state.

The polyhedral shape of the tipping trough 10 shown is a cuboid open at the top with a rectangular trough bottom 12; two vertical, parallel, long rectangular longitudinal walls 14; a vertical transverse wall 16 connecting these and an opposite, slanted transverse wall 18, which allows the two extensions 20 of the two longitudinal walls 14 to protrude laterally and forms an obtuse interior angle with the bottom 12.

On a stable floor, which is to be imagined as being below the tipping trough 10, which is arranged horizontally in the operating state, at a free distance from its floor 12, there is a support 22 which pivots the right-hand part of the trough about its horizontal axis by means of a cantilevered rod 24 forming the tilting axis, the rod 24 being arranged under the sloping transverse wall 18 and connecting the two extensions 20 of the longitudinal walls. The rod support 22 is fastened to the imaginary pen wall by means of screws 26. In the immediate vicinity of the vertical transverse wall 16, a tab 28 is rotatably mounted on the inside of the rear longitudinal wall 14, which extends into a cylindrical guide sleeve 30, which is provided on the side with a clamping screw 32 which secures the lower end inserted in the sleeve 30.

34 of a water supply pipe 36 which is vertical when the tipping trough 10 is arranged horizontally and is suspended from a holding part 38 which is fastened to the bay wall. The suspension consists of a locking sleeve 40 which strikes the underside of the holding part 38 and is firmly seated on the pipe and of a clamping sleeve 42 which is pushed against the upper edge of a lateral slot in the holding part 38 and is frictionally mounted on the pipe and which forms a type of lock with the holding part 38 and the locking sleeve 40.

At the upper end 44 of the water supply pipe 36 there is a membrane-operated shut-off valve 46, to which - not shown - on the one hand an air hose leads, which lies in the pipe 36 and begins at its lower end 34, and on the other hand a water hose leads, which begins at a water pipe located at the top of the stable and has such a looseness that the pipe 36 together with the valve 46 can be removed from the holding part 38 laterally, pulled up and simultaneously moved to the side after the sleeves 40 and 42 have been separated. During this combined vertical and horizontal displacement movement, which in the drawing leads from the left operating state to the right emptying state, the pivot point of the tab 28 is pulled up, whereby it rotates counterclockwise relative to the tipping trough 10 and its left end pivots upwards around the axis of the rod 24, whereby the inclined wall 18 at least reaches a horizontal position so that the filled trough 10 can drain, whereby self-cleaning takes place. The reverse pivoting movement of the tipping trough 10 leads back to the initial state in which, with the valve 46 open, water flows into the trough until its level closes the mouth of the lower pipe end 34. If the water level is to be raised or lowered, the clamping

screw 32 is loosened before adjusting the height of the tube end 34 and then tightened. Accordingly, the locking sleeve 40 is adjusted on the tube 36 and the clamping sleeve 42 is moved.
