RU190921U1 - NECK CLIPPER FOR BIG CATTLE - Google Patents

Abstract

The utility model “Cervical fixator for cattle” refers to the field of agriculture, in particular to devices for fixing the head and body of cattle during veterinary measures, and can be used in peasant farms, livestock farms and other agricultural fields. the model is aimed at reducing the complexity, increasing security, increasing the number of treated livestock per unit of time during veterinary procedures. Cattle is a reinforced metal structure with an automatic locking mechanism and moving arcs, which occupy one of three positions, depending on the stage of the procedure. Arcs have three positions: 1) are open inside the cell; 2) fixed by a locking device; 3) open outward. The latch consists of a rod connecting 2 arcs that rotate in the bushings of the frame and platform and are fixed between two flags attached to the frame. The animal is driven into the cage with its head towards the latch. The head of the animal passes between arcs that rotate towards the locking mechanism. Due to the rotation of the arcs, their edges approach, which ensures the fixation of the animal in the neck and does not allow the head to pass back. Thus, the animal does not have the ability to move forward or backward, as a result of which various veterinary procedures can be performed on the animal.

Description

The utility model relates to agricultural devices for fixing and immobilization of animals (cattle) for the purpose of carrying out the necessary veterinary procedures, and can be used in peasant farms, livestock farms and in other areas of agriculture.

Known machine for fixing cattle, containing hydraulic mechanisms for opening / closing the walls of the machine, neck gates, hinged boards, controls, fixed at the level of a man's belt. The locking neck gates are controlled manually. The machine is equipped with special rubber lining, limiting the review of cattle at the entrance to the machine, which encourages them to move closer to the locking gate (1) (http://agroserver.ru/user/77783/files/467854/dw).

A disadvantage of the known construction is the complexity of its mechanisms. The fixation of the animal is done manually.

Known machine for fixing cattle and hoof processing, which uses a cervical clamp consisting of a lattice metal structure, one of the cells of which has an arcuate rod turning on a hinge. All operations with this lock are made manually (2) (http://uralagro.agroserver.ru).

A disadvantage of the known construction is that the operator has to fasten the animal in direct contact with it, which threatens with injuries and increased fatigue of the operating personnel.

Known machine for fixing a calf, containing a 4-sided box and a device for fixing the body of an animal having lifting straps, while the machine has side walls. The frame consists of vertical rear and front pillars on which doors with elements of animal head fixation are installed, made in the form of a platform, imitating the animal head profile, mounted on the front door butt and fitted with hooks symmetrically relative to each other. Hooks provide fixation of the head of the calf by means of a nylon band or cord with a diameter of 6-10 mm, with the lifting straps attached to two tubes parallel to each other and connecting the upper parts of the rear and front racks. One of the pipes is rigidly connected to the uprights, and the other is provided with bushings rigidly mounted on the uprights. One of the sleeves is made through and provides the possibility of removal and rotation around its axis and winding the lifting belts. The pipe and the through sleeve are interconnected by means of holes located in mutually perpendicular planes of the retainer (3) (Patent RU No. 2228796).

The disadvantage of this machine is the complexity of the design, not a reliable fixation of the animal.

The closest in technical essence and technical tasks is a machine for fixing cattle, which uses a cervical clamp with an automatic mode of operation. The arc synchronization design is made of several complex nodes. When capturing the neck of an animal, additional chains (4) are used (http://hi-hog.com).

A disadvantage of the known construction is the complexity of its mechanisms and the low availability of the warranty service and repair procedure.

This utility model is aimed at reducing labor intensity, increasing safety, and increasing the number of treated cattle per unit of time when performing veterinarian procedures.

The task is solved due to the fact that the latch is a reinforced metal structure (Fig. 1), having an automatic locking mechanism and moving arcs 13, occupying one of three positions depending on the stage of the procedure. The frame of the latch 75 and the platform latch 14 are attached to a massive cage, limiting the possibility of reversal of the animal, which allows you to send his head between the arcs 13.

The figure 1 shows the latch consisting of:

1 - latch knob;

2 - pin, washer;

3 - support flags;

4 - triple canopy;

5 - flag return spring;

6 - axis of flag handles;

7 - fingers of flags;

8 - latch frame element;

9 - checkbox;

10 - support bar flag;

11 - transverse locking rod;

12 - fixing rings;

13 - lock arches;

14 - locking platform;

15 - retainer frame;

16 - bushings with grease fittings;

The latch has provisions:

1) the arcs are open inside the cell (Fig. 2);

2) the arcs are fixed by a fixing device (Fig. 3);

3) the arcs are open outwards (Fig. 4).

The device works as follows: the animal, mainly cattle, is driven into the cage with its head towards the retainer in the first position (Fig. 2), the flags of which are automatically rotated, without operator participation, when arcs pass under them turning under the pressure of the animal's body . With the passage of the head between the arcs 13 and the further forward movement of the animal under the influence of its wide part of the body, the arcs 13 rotate in the sleeves 16 towards the locking mechanism. The synchronism of their rotation is provided by thrust 11. When passing arcs 13 in contact with flag 9, it rotates relative to triple overhang 4, while the edge of flag 9 rises up. Reaching the edge of the second flag, the arc 13 fall into the gap between them, and the raised first flag under the influence of the spring 5 returns to its original position, preventing the reverse movement of the arcs 13.

Having reached the second position (Fig. 3), the arcs 13 are in a fixed state. Due to the rotation of the arcs 13, their edges converged, which additionally ensures the fixation of the animal in the neck area and does not allow the head to reverse. Thus, the animal does not have the ability to move forward or backward, and in combination with other additional fixing devices of the cage, various veterinary procedures can be performed on it.

Due to the large mass of the animal, the retainer is subjected to significant loads. To reduce the risk of deformation of its structural elements, triple canopies of 4 flags 9 are rigidly fastened with a thick support bar of flags 10 and fixed at the ends of the support 3 with guides attached to the frame element 8.

After completing the procedures, the animal is released by lowering the second handle of the latch 1. Handle 1 of the flag 9, turning around axis 6 and, resting the opposite end on the washer and cotter pin 2, lifts the finger 7, the cap of which pulls the corresponding flag 9 upwards, thereby freeing the arches 13 , which under the influence of the translational motion of the animal swing open out.

Reaching the third position (Fig. 4), the second knob 1 is released, ensuring the return of the second flag 9 to its original position under the action of the spring 5. To return the arcs 13 to the first position (Fig. 2), they are manually turned inside the cage. The second flag 9 is raised and lowered automatically, and to overcome the first flag 9, the first handle 1 is used. Thus, the lock returns to the first position and is ready for work with the next animal.
