DE1139685B - Safety device for independent individual coupling and joint uncoupling of cattle, especially on pasture milking trucks - Google Patents

Description

The invention relates to a device by means of which cattle roaming free for the purpose of Feeding, milking, veterinary examinations and other care measures determine automatically. The lock allows groups or individual loosening of those held Animals.

There are devices known as a safety gate, in which cattle found in groups by hand will. All cattle must be in the safety gate with their necks before they can be locked can. It is also known to individually locate the cattle by putting their heads in a push the flap fastened between the feeding bars forward until you can get your head through, to get to the feeding trough. The movable drop flap closes when the Head, whereby the determination is achieved. Another individual determination of the cattle takes place by putting their necks on you as you go down your head to eat Press the cross bar attached to a spar of the feeding fence and thus the mockery into the catching position to press.

The known devices have the disadvantage that once only a group detection is possible all animals to be detected are in the safety gear before closing must and several workers are required to collect. For those equipped with a drop hatch individual safety gates has the disadvantage that the cattle only lift their head and with the Maul has to open the flap to get to the feeding trough. This route to feed is with a dem Cattle is not connected to its own movement and results in a delay in the determination. Devices with a one-sided handlebar guide are due to the release mechanism only for animals of the same size usable. The one-sided opening makes it difficult to push the head through, especially with cattle big horns.

According to the invention, all these disadvantages are avoided in that the locking of the cattle by means of two rods, each movable at a pivot point, the upper and lower ends of which are in a guide rail are movably mounted, takes place, the locking of the rods by movably attached Plates that fall under their own weight and are provided with locking bulges happens. Loosening the cattle is carried out by the weights attached to the rods above the pivot point, provided that the plates, those with a rod through weak chains or safety gear

Wire connected can be lifted by turning a crank.

In the drawing, an embodiment of the invention is shown and explained in more detail.

The device consists of two movable rods 1 attached to a pivot point 2, the upper and lower ends of which run in a guide bar and are brought into a vertical position by a force K acting below the pivot point 2. Additional weights 8 are attached to the upper part of the rods 1. A drop flap 3, on the lower side of which there are locking bulges 6, is attached to the upper guide strips for each rod 1, which fix the rods 1 in a vertical position. The device is thus closed. There are pins between the guide rails that limit the range of motion of the rods. A rod 7 located above the drop flaps 3, which is provided with a crank 5 at the end, causes the drop flaps 3 to be raised when rotated via a wire connection and thus the release of the locking on the locking beads 6. The opening A is released again. By turning back the crank 5, the device is brought back into the catching position. The area between the safety gear and the frame is blocked by bars.

A push rod 10 with cams 9 attached to the upper or lower guide rail has the effect when actuated the closing process of the unoccupied one Lattice,

The device can be put together in various numbers and operated at the same time.

The effect is now as follows: the cow sticks her head through opening A to take up feed and uses her neck to push apart the rods 1 below the fulcrum 2, each movable in a pivot point 2, in order to get to the manger 4. This narrows the space between the two rods 1 above the pivot point 2. Two movable drop flaps 3 provided with locking bulges on the lower side lock the rods 1. The animal is thus trapped.

As soon as the grid is to be opened again, a crank 5 is turned. It is connected to a rod 7, which in turn is connected to each drop flap 3 by wire connections 6. In order to are the drop flaps provided with locking bulges 3 lifted up and the rods 1 released from the lock. Two sideways above the Pivot point 2 attached to the rod 1 weights 8 pull the rods apart so that the The cow can easily withdraw its head from the grid and the original state of the grid is restored.

If the need arises to close the grid when it is not occupied, a cam 9 is provided Push rod 10 below the upper guide rail or above the lower guide rail may be appropriate to pull once to the right and once to the left. The rods 1 are then locked again and can as soon as the grille is opened is to be brought into the collecting position by actuating the crank 5.
