The shedder has transverse crossbars 2, connected by posts 1 through eccentrics 4, at the height of crossbars 2 there are valves 5 with shafts 6 that end with loop 7 for the belt 8 of turning the eccentrics 4 there are handles 10, which at both ends have thickenings 12. When turning eccentrics 4 with handles 10 for 180 ° & in the total amount is the disclosure of the zevnik in three sizes. 5 yl

Description

The invention relates to veterinary medicine, in particular to the sheds

The purpose of the invention is to improve the usability.

FIG. 1 shows a zevnik, eccentrics in the initial position, general view; in fig. 2 - the same, the lower eccentric in the working position, front view; in fig. 3 - a zevnik in the working position, the second upper eccentric in the working position; in fig. 4 - the same, left view; in fig. 5 - a zevnik in the transport state.

Zevnik consists of two racks 1, interconnected by two regulating transverse crossbars 2, which are connected to racks 1 through the eccentrics 4 fixed in bearings 3, on racks 1 are fixed with the possibility of rotation at full angle up to the stop of the valve 5 at the height of crossbars 2, transition control shafts 6, which end with loop 7 for the belt 8, and the eccentric 4 has an opening 9 for the handle 10 for the eccentric 4, and on the rack 1 near the second

The eccentric 4 has a cut 11 for fixing the handle 10, where each handle 10 has a thickening 12 at both ends. The valves 5 are connected to the adjusting shafts 6 by means of thumb screws 13. There are two stops 14 on the housings of the upper bearings 3.

Zevnik works as follows.

Before you start working with a zevnik, you must remove it from the transport state. To do this, release the belts 8 and release the valves 5 with the shafts 6 so that the ends of the shafts 6 with the belts 8 are turned one tooth above the horizontal, rotate the yawner in a horizontal position with the shafts 6 upwards, and the valves 5 are turned as far as the stop 14 and inserted the yawn is put into the oral cavity, turned by the shafts 6 towards the nape of the animal's head, the yaw is firmly fixed with the straps 8 and the joint is fixed by the shafts with thumb screws 13.

If the yawn is not placed earlier on the smallest amount of disclosure, this is achieved by the fact that both eccentrics 4 with transverse crossbars 2 are turned

for the purpose of which the handle 10 of the eccentric 4 is taken from the cut 11. The eccentric 4 is swiveled 180 ° inside the center of the yawning, and the other end of the same handle 10 of the eccentric 4 is fixed in the same cut 11. The other eccentric 4.

The jaws of the animal are opened with two transverse crossbars 2 with a minimum opening. This is recommended because when inserting a zevnik into the mouth of an animal, it resists the insertion of a zevnik least of all and does not damage the toothless part of the mouth. Such a position of the yaw makes it possible to inspect the mouth of the animal. To open the mouth gradually to the second distance, at the free choice of one of eccentrics 4 with cross bar 2, handle 10 of eccentric 4 should be taken out of cut 11, turn eccentric 4 outward of the shed, fix other end of handle 10 11. Another eccentric 4 will remain in the same position.

With the gradual opening of the mouth of the animal to the third magnitude, it is necessary that the second eccentric 4, according to the previous technology, be brought to the side of the shed. This distance is sufficient for holding the hand into the oral cavity.

This approach is safe for the animal and for the worker.

After manipulation, it is sufficient to release the straps 8 on the back of the head of the animal and the yawn is removed from the oral cavity.

Before inserting the zevnik into the transport state, it is recommended to set the zevnik on the first, smallest amount of opening.

Claims (1)

Invention Formula A cattle breeder, including two racks, on which transverse crossbars are mounted, mounted for movement along the uprights, and perpendicular to the uprights and crossbars, of the breech pipe on the animal's head, characterized in that. in order to increase usability, each crossbar is equipped with a movement mechanism along the racks made in the form of fixed on its both ends and on the inner surface of the racks enclosed in bearings, eccentrics with turn handles located on the outer surface of the racks, and the latch on the animal’s head made in the form of valves with shafts mounted on the valves with the possibility of rotation, at the free ends of which are located loops for belts.
