Description

I

This invention relates to the field of veterinary medicine.

The known device for fixing animals, including a swivel bar associated with maxillary grips, and a drive, has an insufficient rigidity in the direction from top to bottom, therefore, with strong bends of the animal's body, the individual grips bend strongly during short-term increased load, which prevents the animals from fixing. In addition, the grips do not compress the animals from above, especially when the pigs are fixed in the feeding groups and sows, and when the animal squats, during the passage of the grips under the chest and abdomen, sometimes the grips rest against the groin or chest-cage behind the shoulder joint and, gaining rigidity in the longitudinal direction, the skin is injured, so that the capture of animals can only be done under the control of the operator.

In order to ensure reliable automatic fixation of animals, increase the speed of capture and prevent injuries, levers are fixed to the rod of the proposed device;

bushings in which spring-loaded grippers of one of the jaws are capable of axial movement. The grippers are located in the guide bushes with side play, and the grips of the second jaw have an axis of rotation located eccentrically with respect to the axis of rotation of the rod or coinciding with it, and are driven by the grippers of the first jaw through the spring-loaded pushers or separate in one.

On fng.1 schematically shows the proposed device, side view; figure 2 - the same, Zid above.

Claims (3)

The rod 1 rotates in the bearings 2 on the bracket 3. The rotation of the rod 1 is carried out by a drive 4 behind the eye 5. The arms of the grippers 6 are rigidly attached to the rod, the lower ends of which are fitted with guides and bushings 7 rigidly mounted at an acute angle to the levers 6. The grippers 8 are fixed in the guide sleeves 7 with weak springs 9. The inner diameter of the sleeve 7 is significantly larger than the outer diameter of the gripper 8, so that the grippers 8 have a large side clearance and at the same time provide a rigid fixation of the animal. Spring mounting provides captures 8 greater freedom in the longitudinal direction. When they stop against the obstacle, they are fully pressed into the sleeve 7. When the animals are fixed, the grippers 8 interact with the clamps 10. The latter, through the axis of rotation 11, are connected to the bar 12 welded to the bracket 3, and through the guide bolt 13 the spring 14 of the clamp and the pusher 15 interact with lever 6 or have self drive. The number of grips 8 on the rotary kggang 1 is not limited, and the distance between them is the same for all animal species (about 12–20 cm, i.e., sufficient for the entrance between them or the hind legs of small animals). In large animals, during fixation, one of the grips rests on the leg and, stretching the spring 9, is pressed into the guide sleeve 7. Thus, the clearance for the leg between the grips will be doubled. After fixation, the claws and clamps are retracted to position I. To fix the animals from position .1, the claws 8 are pushed forward with the lead 4, which by the ear 5 rotates the rod 1 with the lever 6. With the help of the guide sleeve 7, the clamps 8 ts under the bodies of animals that are in a split. Simultaneously and synchronously with the claws 8, the pushers 15, the spring 14 of the clamp and the guide bolts 13 force the force to the clamps 10. They are lowered towards the claws. Even before the end of the capture of animals, the fixation device, through bracket 3, begins lifting the entire fixation unit over the split. When the fixation unit is lifted, the animals, with their head, torso and huts, lie completely on the claws 8 and at the same time press the clamps 10 against the claws 8 and snarl 6 from above and from the aprug side. The stronger the animal is, the cauterization aa 10, because spring 14 is in a more compressed state. The strongly inclined position of the grips 8 helps the animal to slide toward the arms b, and the spring-loaded enough clips 10 add to the fixation of the animal. The animal is in a triangle, the two sides of which provide a rigid fixation, and the third, represented by the clamp, is mobile, but, thanks to the strong spring 14 of the clamp, fixes an animal of any size. If, at the moment of capture of the animal, one or several grips 8 are pressed into the side or foot of the animal, then they, due to the weak spring 9, are pressed into the guide sleeve 7 and will not participate in the fixation of the animal. Claim 1. A device for fixing the belly Hfax, including a swivel bar associated with maxillary clamps, and a drive, characterized in that the levers are fixed at the ends to ensure reliable automatic fixation of animals, increase the speed of trapping and prevent injuries. which have guide bushings in which spring-loaded grippers of one of the jaws are positioned with the possibility of axial movement. 2. A device according to Claims 1, 6, tl and chiu so that the clamps are installed in guide sleeves with side play. 3. A device according to claim 1, characterized in that the grips of the second jaw have a pivot axis located eccentrically in relation to or to the axis of rotation of the rod or coinciding with it, and are driven by the first jaw grips via spring loaded pushers or a separate actuator. ./
