The invention relates to a self-drinking pasture pump with an elongated drinking bowl a with the pool end assembled pump actuating pendulum rocker, which at the ends of two longitudinally engaging one behind the other on the pump housing, forming a four-bar linkage Handlebars is articulated, the handlebar facing away from the pelvis under cover of the hinge axes the pendulum rocker with a pump piston or a pump diaphragm actuating Plunger is connected.

In known pasture pumps of this type, the four-bar linkage for supporting the pendulum swing arm is located or the pump handle forming and the actuation of the pump serving, in the longitudinal direction Distance from each other arranged handlebar levers and also the lower joints above the Pump housing completely free, and only the joints between the pendulum swing arm and the handlebars are covered in a known design by an upper bridge of the pendulum swing arm, but freely accessible to the front and rear.

It is understandable that the joints are thus directly exposed to weathering and pollution are exposed and that drifting sand or the like. Can get into the joints, so that jamming occurs can, through which the pendulum swing after actuation by the head of the animal under certain circumstances does not return to the starting position in which it has lateral access to the Should lock the basin. When the pendulum swing arm is operated by an animal, a another approaching animal with its mouth or a head part between the handlebar and the The pendulum swing arm can be pinched and injured, or an animal may hit the Horns get between the handlebars and even the whole pump through a hook take along.

In order to remedy these disadvantages, the invention consists in that in the self-drinking pasture pump mentioned at the beginning the handlebar lever facing away from the pelvis as U-shaped in section, in side view approximately triangular, downwardly open cap is formed, the side walls of which Form bearings for their two joint axes and both the articulation to the pump and the the pelvis covered handlebars and that the also in section U-shaped, down and closed The pendulum swing open to the handlebars with its side self-watering pasture pump

ίο turns in every position at least partially in the handlebar cap reaches into it.

This means that all joints are completely protected under the handlebar cap, which serves as a handlebar lever, because the side of the cap facing the free pool end is also made practical by the cap-shaped one Pendulum swing arm covered, and both caps are only down, the elongated drinking bowl opposite, open, but with the pendulum swing also covered at the bottom

zo can be. The invention also means that there are no free spaces that are somehow accessible from the outside, so that injuries to the animals are no longer possible and the animals can no longer get their horns between such parts.

The invention will now be explained in detail using an exemplary embodiment of the drawing, namely shows

F i g. 1 is a side view of the self-drinking pasture pump according to the invention,

F i g. 2 a vertical longitudinal section through the self-drinking pasture pump,

F i g. 3 is a top view with a partial horizontal section along line HI-III of FIG. 2,

F i g. 4 the outer cover of the handlebar axles running transversely through the handlebar cap in Cut.

According to the embodiment, the self-drinking pasture pump consists of an elongated drinking bowl 1, for example made of cast iron, which can be placed or fastened with feet 2 on the ground or on a support. In the case of the embodiment of the bottom of the drinker at the free end at la is only slightly inclined and runs out flat towards the free end, and said bottom inclination then proceeds in a trough-shaped recess 1 b through. The lower part 3 of a pump, for example a diaphragm pump, connects to this trough-shaped depression, in which the larger amount of water accumulates, through which the animal is stimulated to exercise a larger lever stroke, wherein this lower part forms a cast part with the basin 1 or else can be flanged. The lower

part 3 of the pump is covered by a flanged upper part 4, and between these parts is a membrane 5 is attached, which protrudes with a plunger 6 from the upper housing part 4. This upper housing part 4 is provided on both sides of the plunger 6 with two upwardly drawn ribs 7, which the bearing blocks for the axles 8 and 9 of two control arms 10 and 11 form. The handlebar lever 11 is now designed according to the invention as a cap, the side walls as flat surfaces or are pulled down as curved surfaces, so that this handlebar cap 11 is only down to Drinking bowl and towards the free end of the drinking bowl is open.

In this embodiment, the pelvic arm 10 swings between the housing ribs 7 the axis 8, while facing away from the ground, designed as a cap handlebar lever 11 on the Outer sides of the bearing ribs 7 can be pivoted about an axis 9. The cap 11 is on the inside provided with a rib-shaped stiffener 11 α, the articulated with its lower part at 14 on the diaphragm plunger 6 attacks.

The pendulum rocker 15, which is also designed as a cap, has a cleat at the free end

16 provided, and their side walls 17,18 are down to about above the edge of the pool pulled while the edge facing the pump

17 a of these side walls 17, 18 with a small spacing within the cap walls 12, 13 lies. This pendulum rocker 15 is articulated about the upper axis 19 on the link arm 10 on the pelvic side and on the other hand is pivotably supported within the cap 11 by a journal 20.

Characterized in that the one handlebar lever 11 as a cap with downwardly drawn side walls 12, 13 is formed, all hinge axes 8, 9 and 19, 20 are protected below the cap and also the pelvic-side handlebar lever 10, while the open side of the cap facing the free end of the pelvis is practically covered by the pendulum swing arm 15, which is also cap-shaped. Run it only the handlebar axles 9 and 20 transversely through the cap 11 and are shown in accordance with FIG. 4th Protected against penetration of dirt or the like from the outside by a push-on cap 21.

The mode of operation of the self-drinking pasture pump corresponds practically to the usual known pasture pumps, i.e. the animal pushes against the butt plate 16 to actuate the pump so that the The pendulum rocker 15 swings into the handlebar cap 11, the handlebar axles 19 and 20 raise slightly and pivot the handlebars 10 and 11 about the axes 8 and 9 and thereby the membrane actuate the pump to execute the suction stroke. After this suction stroke has been carried out, the Pendulum swing arm 15 automatically into the position shown in FIG. 1 and 2 position shown back, so that the animal now can pump again. This automatic return of the pendulum swing takes place in that the common center of gravity of all moving parts arcs up from the rest position.

So that the overall center of gravity of the self-drinking pasture pump is as low as possible and thus one high stability is achieved, the handlebars 10 and 11 as well as the pendulum swing arm 15 can be made Consist of light metal, e.g. cast from light metal.
