Implementation of the invention

In FIG. 1 shows a front view of a rotary machine for artificial insemination of sheep, which is made of a metal profile and consists of a main 1 and an inner frame 2, which are interconnected by a rotary mechanism 3. On the front frame 4 (Fig. 1) of the inner frame 2 there is a double-leaf semi-automatic gate 5, fixed with the help of hinged hinges 6 with return springs 7. Identical doors of a two-leaf semi-automatic gate 5 are fixed by means of a semi-automatic latch 8 and have a cone-shaped gap 9 for accommodating a sheep's neck with fixation of the head using a cross-shaped self-fixation mechanism of the animal's head 10 with an automatic latch 11.

On the side grating 12 of the inner frame 2, located at an obtuse angle to the floor, there is a locking rod 13 of the inner frame 2 (Fig. 2) and a mechanism for fixing the rear part of the body 14 (Fig. 5) of the animal, consisting of a side clamping flap 15 (Fig. 3), adjustable stem 16 and shut-off gate 17.

Rotary machine for artificial insemination of sheep works as follows.

The animal enters the rotary machine for insemination of sheep, passes forward until it stops with its shoulders into the identical doors of the semi-automatic double gate 5, where it raises its head up, the cruciform self-locking mechanism of the animal's head 10 with automatic latch 11 is activated, after which the animal can no longer lower its head down or take it out head back.

After self-fixation of the sheep's head in the cone-shaped gap 9, the operator raises the locking rod 13 (Fig. 2) of the inner frame 2, activates the rotary mechanism 3 and turns the machine by 90° (Fig. 4), while the cut-off gate 17 rests against the rear frame of the main frame 1 blocking the passage of the animal from the split, at the same time the side clamping flap 15 fixes the back of the animal by transferring force through the adjustable rod 16 and the animal is immobilized in the machine by pressing the sheep against the opposite side grate 12 of the inner frame 2 located at an obtuse angle to the floor and at the same time, the operator turns the fixed animal with its back to the inseminator and fixes the comfortable position of the inner frame by lowering the fixation rod 13.

The mechanism for fixing the rear part of the body 14 of the animal consists of a shut-off gate 17, a side clamping flap 15 and an adjustable rod 16, which allows you to adjust the fixation mechanism in accordance with the size of the animal.

This turret for sheep artificial insemination was designed taking into account the behavioral response of sheep, the use of a rotator and animal fixation mechanisms.

Animal fixation mechanisms can be used both simultaneously and separately from each other.

At the end of the manipulations with the animal, the machine is turned back to its original position, as a result of which the cut-off gate 17 is moved away, the sheep is released from fixing the rear part of the body, then it is released without unlocking the cruciform mechanism for self-fixation of the head 10. The animal is released from the rotary machine for artificial insemination of sheep by lifting the semi-automatic latch 8, which acts on the principle of an elastic element, fixing the doors of the two-leaf semi-automatic gate 5, and automatically returning to its original position by means of return springs 7, with the closing of the two-leaf semi-automatic gate 5. When the sheep moves to the exit through the inner 2 and main 1 frames, the leaves double-leaf semi-automatic gates 5 open at an angle of more than 90 ° to the direction of movement of the sheep and after exiting automatically close with fixation of the semi-automatic latch 8. This function is carried out by attaching a double-leaf semi-automatic gate to gates 5 to the front frame 4 of the inner frame 2, consisting of hinged hinges 6 with a return spring 7. Hinged hinges 6 ensure that the leaves of identical doors of a double-leaf semi-automatic gate 5 are held in the opening of the front frame 4 of the inner frame 2 and provide for proper functioning associated with reliable opening and by closing the identical leaves of the double-leaf semi-automatic gate 5. The return spring 7 ensures the automatic return of the identical leaves of the double-leaf semi-automatic gate 5 to the initial closed state, acting on the principle of a mechanical closer, which reduces the wear of the hinged hinges 6, and the cycle of work with the next animal is repeated.

This invention is made of a metal profile and is intended for fixation and artificial insemination of sheep sequentially coming from the split of animals, as well as for other veterinary activities, both indoors as part of the technological equipment of a complex-mechanized sheep farm or an independent unit, and in pasture conditions, year-round .

The use of a rotary machine for artificial insemination of sheep eliminates the need for capital facilities and premises for artificial insemination of sheep, thereby helping to reduce material costs. The versatility of the invention testifies to its versatility, in addition, it is convenient in storage and transportation, and also helps to reduce manual labor costs.

The rotary sheep artificial insemination machine is applicable in the sheep breeding industry.

The advantage of the proposed rotary machine for artificial insemination of sheep in comparison with existing technical solutions is the presence of mechanisms for cutting off the flow of animals and fixing the animal selected by the operator, in combination with a rotary mechanism, which reduces manual labor costs, allows for a number of veterinary and zootechnical measures, and the presence the rotary mechanism allows to carry out at the same time several operations; the design is made of inexpensive materials, easy to manufacture and use, it can be transported.

Artificial insemination and other veterinary activities are becoming more efficient, convenient and less traumatic in comparison with similar activities in other devices.
