Description

The invention relates to agriculture, in particular animal welfare.

An object of the invention is to increase the reliability of animal welfare.

This goal is achieved by the fact that in the well-known grip for cows, containing a collar with a flexible pull, on the free end of which there is a load, and pairs of guide elements mounted on a support for each pull with a locking latch connected with a longitudinally movable horizontal rod equipped with a fork, interacting with the rod, made in the form of a finger of the latch, the guide elements for flexible traction with load are bent from the feeder at an angle not less than the angle of friction of the material of the flexible traction along the material the constituent elements, and center to center distance between the reference pin and the pin scavenger by abutment with a retainer is determined depending on

A B + b - (- 2d + y + a, (1) where B is the width of the stop plate;

b is the distance between the catcher pins;

d is the diameter of the catcher pins;

y-free end of the latch;

and - the free movement of the latch in the catcher pin from the stop.

In this case, the free movement of the latch in the catcher pin on the stop side, which ensures reliable operation of the device for animals, is within

.

Fig. 1 is an animal side view; in FIG. 2, same top view; Fig. 3 is a design diagram for determining the center-to-center distance between the support pin and the catcher pin from the stop side with a fixer.

The animal lash contains a collar 1 with a flexible pull 2, on the free end of which a load 3 is secured. The lanyard is equipped with a locking device, which consists of pins 4 with guide elements 5, a latch b and a control rod 7 with an emphasis 8, the support pin 9 and the bracket 10. The pins 4 are rigidly mounted on the frame 11.

On each of the pins 4, respectively, there is one guide element 5, which are bent from the feeder 12 by an angle Q, the value of which is not less than the friction angle of the material of the flexible rod 2 according to the material of the guide elements 5, that is:

(2) where is the indicated friction angle.

The angle a (the bending angle of the guide elements 5 from the feeder 12) is measured from the vertical plane N, perpendicular to the axis 13 of the animal stall (see Fig. 2).

The support pin 9 is fixedly mounted on the frame 11 of the sling. The catcher pins 4 and the support pin 9 have openings 14: The latch 6 has a handle 15 and a pin 16 and is arranged to move in the holes 14 of the support pin 9 and the catcher pins 4.

The handle 15 and the finger 16 of the latch 6 5 are located on both sides of the support pin 9. A control rod 7 with an emphasis 8 made in the form of a fork is horizontally placed along the feeder 12. A stop 8 is placed between the support pin 9 and the catcher pin 0. The bracket 10 is rigidly fixed to the end of the frame 11 adjacent to the support pin 9 and is located with the possibility of engagement with the handle 15 of the latch 6.

An animal liaison operates as follows.

The control rod 7 through the stop 8. being in engagement with the finger 16 of the latch 6, leads out of the hole 14 of the pin 4 of the free end of the latch, freeing 0 the gap between the two pins A of the catcher. The center-to-center distance (A) between the support pin 9 and the pin 4 from the side of the stop 8c with the latch is selected so that when moving the bolt-5 summer b by means of the stop 8 under the influence of traction 7 (in Fig. 2, the ha 7 moves to the left). the free end of the latch 6 of length (y) moves to the left by the value of its stroke equal to: 0 (b + d + y). (3)

The magnitude of the stroke, the latch is defined as: by the dependence (3), must be provided by the relative position of the structural elements (pin 9, stop 8 5 and pin 4 from the side of the stop 8) in the form: xChA-dB (4) Expressions (3) and ( 4) determine the course of the latch, ensuring satisfactory operation of the latch, therefore, the indicated expressions (3) and (4) are the equations of system (5): x AdB

x b + d + y (5) Having solved system (5) with respect to (A),

teach

A B + b + 2d + y. (6) Expression (6) defines the center distance to ensure reliable operation, but it is nominal

its meaning. In this sense, there is a tolerance field that provides the previous conditions, but which, when installed, will provide the ability to select dimensional chains of the clamp elements. After the tolerance is determined by the free-wheeling (A) of the end of the latch 6 in the catcher pin 4 from the stop, that is, the parameter (A) can be increased by dependence (6) by (a) in the form:

A B + b + 2d + y + a. (7)

In this case, the free movement of the latch in the catcher pin on the stop side, which ensures reliable operation of the device for the connection of animals, is within:

About a d. (8)

If the distance (A) is less than the optimum defined by expression (7), then the free end of the latch will not completely free the distance (b) between the pins 4, which will impede the connection or connection of the animal and reduce the reliability of the device.

If the distance (A) between the indicated pins 9 and A from the stop 8 side is more than optimal, expression (7), then the free end of the latch pops out of the hole 14 pin 4 from the stop 8 side. To prevent this, the distance (A ) between the pins 9 and 4 from the stop 8 should be selected according to the dependence (7). The free movement of the latch of the bag 7 will be limited by the width of the plate (B) of the stop 8 and equal to (x) (see Fig. 3).

When approaching the feeder 12, the animal is brought to the feed located in the feeder, while the flexible rod 2 slides along the guide elements 5 of the catcher. Since the guide elements 5 are bent from the feeder (Fig. 2) to an angle not less than the friction angle of the material of the flexible rod 2 according to the material of the guide elements 5, the flexible rod 2 with the load 3 is guided into the space (b) between the pin catcher 4, regardless of where the bending of the rod 2 is touching the guide elements 5. Due to the fact that the guide element 5 is bent from the feeder by the angle determined by the dependence (2), the bending rod 2 has the ability to move freely in the direction of the pins 4 for fixing.

After the bending of the bar 2 with the load 3 is between the pins 4, the control bar 7 by means of the stop 8, which is engaged with the pin 16, introduces the latch 6 into the hole 14 of the pin 4. Thus, the animal will be tied.

In order to bind the animal with the control link 7 by means of the abutment 8. which is engaged with the pin 16, the free end of the latch is disengaged from the 5 holes 14, freeing the distance (b) between the pins 4.

An individual animal may be kept in the following manner. By turning the latch 6, the finger 16 is withdrawn from the chain e0 with a stop of 8, and the handle 15 is inserted into the bracket 10. To individually unhook the animal by turning the latch 6, the finger 16 is disengaged from the stop 8. The latch manually by the handle 15 output t

.5 holes 14, freeing the gap (b) between the pins 4.

The effectiveness of the application of this vaccine for animals is that the livestock conditions are improved.

It is possible to quickly and reliably recover animals in an emergency situation (in case of fire in the premises of the livestock farm), which will contribute to their conservation.
