SU946473A1 - Forceps for marking animals - Google Patents

Description

The invention relates to tools for labeling animals and can be used on livestock farms for labeling cattle, sheep, pigs, etc.

Tongs for marking animals are known, including pivotally interconnected levers with jaws, on which working elements are fixed in one - for punching a hole, in others - for closing the washer on pin 1.

The disadvantage of such forceps is the laboriousness of the animals and the low productivity, as the hole in the ear of the animal punched by forceps and punch is set manually and then fixed with a forceps and fixator.

Also known are tongs for marking animals, including arms that are pivotally interconnected, one of which has a support and the other of the jaws.

A disadvantage of the known tongs is that the labor productivity remains low, since it is necessary to put a new mark in the tongs every time. The safety of such tags on the ear of an animal does not exceed 80-85%, the rest are lost due to the presence of protruding parts of the tag on both sides of the ear: what is the basis for hooking onto fencing stalls, tree branches, wool of another animal, etc.

The purpose of the invention is to increase productivity when attaching ear tags.

This goal is achieved by the fact that in the forceps for fixing the ear tags of animals, the lever with the pressure sponge is made of the POLEM and equipped with the tag mechanism, the tag ejector, and the support sponge is equipped with a figured matrix that interacts with: the ejector.

The tag feeding mechanism is made in the form of loosely mounted on the guide rod with the T-end of the magazine, the feeder and the compression spring.

Claims (2)

The matrix has a profile-curved side walls and tabs. FIG. 1 shows the forceps, a partial cut-out of the walls; in fig. 2 - section A-A in FIG. one; in fig. 3 is a diagram of the attachment of the mark on the ear of the animal The animal tagging tongs contain lever 1 with support sponge 2 and ЕА chag 3 with gland sponge 4, interconnected pivotally with axis 5 and torsion spring b, which holds the levers in the open position. The support sponge 2 is provided with a matrix 7 having profilely curved side walls 0 and a tongue B. An ejector 8 is rigidly fixed on the movable sponge 4. The lever 3 is made hollow and removed by an automatic tag feeding mechanism consisting of a magazine 9, a feeder 10 and a compression spring 11 . The feeder 10 and the compression spring 11 are freely seated on the guide rod 12, the end of which is T-shaped. The hollow rectangular box 9 has one notch 13 in the front part of the cut-out, and a latch 14 in the rear part to hold the T-shaped end of the guide rod 12. The automatic label feeding mechanism is fitted with forceps The hollow arm 3 is hingedly attached to the slot 15 by means of a T-shaped end of the guide rod 12. The automatic feeding mechanism for the tags under the spring is made of a spring element made in the form of a plate spring 16 fixed on the lever 1 by a screw 17. Forceps work as follows B The magazine 9 places the marks 13 (20-25 pieces), presses the front part with the feeder Yu and the compression spring 11 and locks the T-shaped end of the guide rod 12 in the latch 14. In this form, the automatic tag feeding mechanism inserts the lever 3 into the floors secured with the same T-shaped end of the guide rod 12 in the latch 15. The tongs are ready for use. To secure the mark, the animal's ear is placed between the jaws 2 and 4 and pressing the levers 1 and 3 bring the bearing 2 and the jaw 4 together to overcome the resistance of the torsion spring 6. The automatic tag feeding mechanism, in contact with the animal's ear, enters the hollow space of lever 3. The extreme mark 13, interacting with the ejector 8, comes out of the store 9, its pointed legs pierce the animal х-r, slides along the shaped walls of the matrix 7 and ter limiting stability, folds, taking place under the tongue 6 of the matrix 7. Then, the arms are removed from the levers 1 and 3, the torsion spring 6 pushes them apart, freeing the animal's ear from (, - forceps, and because the tongue 8 of the matrix 7 slightly shorter than the width of the mark 13, the last removed from the tongue in, remaining attached to the ear of the animal. Plastised spring 16 deflects the automatic feeding of tags to the lowest position relative to the hinge mounting point of the automatic feeding of tags into the latch 15. At the same time, the ejector 8 releases space in the front part of the magazine 9 The feeder 10 and the compression spring 11 push the marks 13 forward, driving the forceps to the position ready for tagging the next animal. U-shaped marks 13 with pointed legs are made of corrosion-resistant and harmless to the body of animal material, have sufficient strength for punching the cartilage of the ear of an animal and keep their shape well. Such a tag, attached to the ear of the animal (Fig. 3), has no protruding parts, does not catch on bushes, tall grasses, etc., which ensures its long-term preservation. The use of these forceps on cattle-breeding complexes improves productivity when fixing ear tags by 5–7 times ensures the preservation of marks practically throughout the biological life of animals, greatly simplifies and facilitates the labeling process itself. Claims 1. The tongs for marking animals that contain hinge-connected levers, one of which has a support and the other a pressing sponge, characterized in that, in order to improve performance when fixing the ear tags, the lever with the pressing sponge is hollow and equipped placed in it by the tag feeding mechanism and tag ejector, and the support sponge is provided with a figured matrix interacting with the ejector. 2. The tongs according to claim 1, distinguished by the fact that the tag feeding mechanism is made in the form of freely set on the guide rod with the T-end of the magazine, the feeder and the compression springs. 3. Nippers according to claim 1, characterized in that the matrix has profile curved side walls and a tongue. Sources of information taken into account in the examination 1.
