The present invention relates to a pen with a feed hopper.

There are two types of pens, more specifically long pens and short pens.

A long pen means that a cow can stand and lie on its own podium along its entire length. This means that when a cow reaches the feed table, it stands further on the podium and when it defecates, the manure drips down onto the podium itself. This requires, on the one hand, cleaning the podium by hand and, on the other hand, causing the manure on the podium to soil the cow.

By short pen is meant that the pen is so short that the standing cow or its head is above the feed table. In this case, the cow is always forced to defecate in the manure trough itself.

This prevents contamination of the manure platform. In addition, such pens take up less space, which is an advantage in terms of construction costs.

2 62929

The present invention relates to an arrangement by means of which the permanent and temporary tying of a cow to its pen can be changed in a simple manner in a short pen. Permanent tethering is particularly relevant during the winter, when cows stay in their pens around the clock, while temporary tethering comes into question, for example, when cows come from a green pasture in their barn for milking.

According to the present invention, there is provided a short pen for a cattle comprising a feed gate that is pivotable between two positions, in the first position the cow can stand but not on the ground holding its head above the feed table and in the second position the cow can both stand and lie on the ground above the feed table. The pen according to the invention is mainly characterized in that, in the first position, the gate is arranged approximately vertically above the front edge of the feed table and is such that the animal can reach the feed table only by inserting its neck from above into the gate opening, at least the lower part of the opening being narrower than the cow. the gate is pivotable about a horizontal pivot axis extending across the longitudinal direction of the pen, so that after turning 180 ° it enters said position where the gate leaves the road free on the animal under the gate and / or through said now downward opening.

The invention will be explained in more detail with reference to the accompanying drawing, in which Fig. 1 shows an embodiment in which the feed gate is located in the first position, and Fig. 2 shows the same feed gate in the second position.

In Figures 1 and 2, reference numeral 1 denotes a feed table and reference numeral 2 denotes racks consisting of vertical tubes cast on the floor as well as a top beam 3 formed by the tube. This top beam supports bearings 4 by means of which the feed gates 5 can be turned. The gates are locked in the respective positions by means of locking elements, which are not known per se, but which are not shown. The gate 5 consists of a frame made of a tube, comprising a tube bracket 6 delimiting an opening 11 which is open upwards in Fig. 1 and which has an upper extension which narrows to a lower portion adapted to pass through the cow's neck but not the cow's 3 62929 head. for implementation. In addition, the top beam 3 supports columns 7 supported by a top beam 8 extending along the entire row of pens. By means of the lever arms 9 pivotally mounted on the posts 7, a horizontal neck boom extending over the entire row of pens can move vertically between the lowest (Fig. 1) and the highest (Fig. 2) positions, in which positions it can be locked. Parts 5-8 and 10 are also suitably tubes. The device works as follows:

Figure 1 shows the position of the gate 6 when the cow is temporarily tethered, e.g. when it has been taken in from the pasture for milking. As the cow enters its pen, the boom 10 is in its upturned position, shown in Figure 2. To reach the feed on the feed table, the cow lowers its head from top to bottom in the bracket 6. When all the cows have done so, the boom 10 is lowered to the position shown in Figure 1, locking the cow into the handle because the neck boom 10 prevents it from raising its head. In this situation, the cow also cannot lie down.

Figure 2 shows the position of the gate 5 and the boom 10 when the cow is permanently tethered as in winter time. In this case, the cows are tethered with a special hook that allows them to both stand and lie down by holding their heads above the feed table. While standing, the cow can insert its neck into the bracket 6 from below, while the gate branches formed on both sides of the opening 11 form shoulder supports that prevent the cow from moving onto the feed table. Since the bearing 4 is positioned asymmetrically relative to the center of the gate in the vertical direction, a gate is raised half turn the position of Figure 1, so that the cow lying down may prejudice the gate to reach the feed table.

The lock boom (10) shown in the drawing is only one example of a lock device suitable for temporary tying. Other locking devices can also be used. Another example is a device comprising a horizontal bar that can pivot about its longitudinal axis and portions arranged on the bar in pairs above each gate bar, which by turning the bar can be made to join downwards into the bracket opening so that the width of the animal's neck is "extended" and prevents the cow from pulling its head back even when it holds its head up.

Claims (4)

62929 4 1. A short pen with a feed gate which can be turned between two positions, in the first position the animal can stand but not on the ground by holding its head above the feed table and in the second position the animal can both stand and hold the head above the feed table, characterized in that the gate (5 ) in the first position is arranged approximately vertically above the front edge of the feed table and is made so that the animal can reach the feed table only by inserting its neck into the upward opening (11) of the gate (5) from above, the bottom of the opening (11) being narrower than the cow's head. the gate can be pivoted about a horizontal pivot axis extending across the longitudinal direction of the pen, so that after turning about 180 ° it enters said second position where the gate leaves the road free on the animal under the gate and / or through said now downward opening (11) A short pen according to claim 1, characterized in that the opening (11) comprises, in the first position, an upper part which is wider than said lower part. A short pen according to any one of the preceding claims, characterized in that said pivot axis is arranged asymmetrically vertically with respect to the center of the gate, so that the lowest part of the gate is in a lower position in the first position than in the second position. Short pen according to one of the preceding claims, characterized in that the raising and lowering boom (10), which is substantially parallel to said pivot axis and which may be common to several pens in a row, is arranged in the first position of the gate (5) to close the animal's neck (11). i.
