Description

Technical Field

[0001] The utility model relates to the technical field of dairy cow breeding auxiliary equipment, in particular to an anti-kicking device for dairy cow milking. Background Art

[0002] Milk is one of the oldest natural dairy products with great nutritional value. The source of milk for milk production mainly comes from dairy farms. Large-scale farms are generally equipped with relatively complete milking equipment, which can basically realize automatic milking, and there is basically no cow kicking during the milking process. However, for some small farmers or farmers, due to the small number of dairy cows, they do not have the conditions to install automatic milking equipment, and generally use manual milking to collect milk sources. Therefore, anti-kicking equipment is needed to prevent cows from kicking people during milking.

[0003] For example, the Chinese utility model patent with announcement number: CN216627084U specifically discloses a cow anti-kicking device for milking, including a trunk fixing belt and a hind limb anti-kicking frame; the trunk fixing belt is used to fix on the trunk of the animal body and connect the hind limb anti-kicking frame; the trunk fixing belt is in the shape of a long strip, and its two ends are connected to form a closed loop by a connector; along the width direction of the trunk fixing belt, one side thereof extends outward and is connected with a first connecting rope; the hind limb anti-kicking frame is in a non-closed loop quadrilateral shape, which is used to be clamped on the upper part of the hind limb of the animal body to limit its range of motion; the hind limb anti-kicking frame is connected with a third connecting rope; the first connecting rope and the third connecting rope are connected by a buckle. When using this device, the trunk fixing belt and the hind limb anti-kicking frame need to be fixed on the cow, and more contact and interaction with the cow are required during the fixing process. During the installation process, the operator has more direct contact with the cow, and the installation operation is relatively cumbersome, which can easily cause the cow to kick people in agitation.

[0004] Another example is the Chinese utility model patent with the announcement number CN207467403U, which specifically discloses a cow anti-kicking auxiliary clamp for milking, comprising two parallel and spaced vertically arranged sleeves, the upper ends of the two sleeves are respectively connected with connecting pipes extending obliquely upward and downward from the inner sides of the two sleeves, and an elastic plate capable of adjusting the separation angle of the two sleeves is connected between the extended ends of the two connecting pipes; the tube cavities of the two sleeves are respectively inserted with telescopic rods that can only slide up and down, the lower ends of the two telescopic rods respectively extend downward from the tube cavities of the corresponding sleeves, and a locking device for adjusting the extension length of the telescopic rod is provided between the sleeves and the telescopic rods, and the lower ends of the two telescopic rods are respectively provided with arc rods that are arc-shaped and bent upward and downward from the inner sides of the two telescopic rods, and the ends of the arc rods are respectively covered with elastic sleeves. The whole device includes a relatively large and long rod-shaped part, so it is very easy to cause panic and agitation of cows when installed and used. Utility Model Content

[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0026] In the present invention, unless otherwise specified, the directional words used, such as "upper, lower, top, bottom", are usually relative to the directions shown in the drawings, or relative to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the contours of the components themselves, but the above directional words are not used to limit the present invention. The present invention will be described in detail below with reference to the drawings and in combination with embodiments.

[0027] The following is a description of the anti-kicking device for milking cows in conjunction with the accompanying drawings. The device is mainly used for small farms or individual farmers to prevent kicking during milking. Cows kick people mainly with their hind legs during milking, specifically, the force is exerted by the lower part of the knee joint of the hind leg of the cow and the force is exerted through the hoof. Therefore, in order to prevent kicking, the hind legs of the cow are mainly targeted. The utility model mainly reduces the instantaneous explosive force of the cow's hind legs by limiting the range of motion of the calf. Moreover, the utility model does not completely fix the cow's legs, which can prevent the cow from becoming restless due to the restraint and fixation of the legs.

[0028] Example 1

[0029] like Figures 1 to 3 as well as Figure 5 As shown, an anti-kicking device for milking cows includes a main body 10; the main body 10 is in a rectangular shape, the width of the main body 10 is 20-30 cm, and universal wheels (not shown in the drawings) are arranged at the four corners of the bottom of the main body 10. The universal wheels have brakes and are fixed by the brakes when in use to prevent the main body 10 from sliding through the universal wheels. The top of the main body 10 is an operator seating surface 101, that is, the main body 10 can provide the function of a bench, and the operator can sit on the seating surface 101 to perform milking operations to avoid fatigue caused by long-term bending or squatting operations.

[0030] In order to prevent the operator from being kicked by the cow during milking, a retractable anti-kick component is provided on the main body 10, which can prevent the cow from kicking the operator during milking. Specifically, the anti-kick component is arranged on both sides of the main body 10 in the length direction.

[0031] Specifically, during milking operation, the anti-kick assembly can be unfolded on (or extended to) one side of the main body to limit the cow's hind legs. The anti-kick assembly limits the range of motion of the cow below the knee joint, specifically reducing the space for lifting the legs forward and kicking the legs backward. During non-milking operation, the anti-kick assembly shrinks and is accommodated inside the main body.

[0032] In this embodiment, the anti-kicking component includes two limit rods 201, and the two limit rods 201 are respectively located on both sides of the length direction of the main body. During the milking operation, the two limit rods 201 are rotated and unfolded to (or extended to) the outside of one side of the main body, so that the parts of the two limit rods 201 located on the outside of the main body 10 are parallel at a fixed distance, and the cow's hind legs are located between the two limit rods 201, and the part below the knee joint of the cow's hind legs is located between the two limit rods 201, wherein the limit rod 201 located on the front side of the cow's hind legs is used to limit the forward leg-lifting position of the cow's hind legs, and the limit rod 201 located on the rear side of the cow's hind legs is used to limit the backward leg-kicking position of the cow's hind legs.

[0033] As a specific solution in the above embodiment, the two limiting rods 201 are straight rods, one end of each straight rod is hingedly arranged on both sides of the main body 10, and the other end is a free end. The straight rod can be horizontally flipped with the hinge as the axis, that is, each straight rod can be attached to the outside of the main body 10 and rotated 180° in the horizontal direction with the hinge as the axis, so that the straight rods are parallel to each other on the outside of the main body 10, and a limiting area 30 for accommodating the corbel is formed between the two straight rods, and the limiting area 30 is the space where the corbel can move. At the same time, in order to ensure that each of the two unfolded straight rods remains in a parallel relative state, the anti-kick assembly also includes a connecting rod 202.

[0034] When not in use, the two straight rods are against the side wall of the main body 10; when in use, the two straight rods are unfolded on the same side of the main body 10, and the two unfolded straight rods are connected by a connecting rod 202 to ensure that the distance between the two straight rods remains unchanged.

[0035] Preferably, the connecting rod 202 is telescopic, and is specifically telescopic by using a threaded rod and an outer cylinder with an internal thread. One end of the connecting rod 202 is provided with a cylindrical fixing ring 2021, and the other end is fixedly provided with a semicircular clamping ring 2022; the fixing ring 2021 is mounted on one of the straight rods, and the connecting rod 202 can rotate at any angle with the straight rod where the fixing ring 2021 is located as the axis; when not in use, the connecting rod 202 is suspended under the straight rod by the fixing ring 2021; when in use, the clamping ring 2022 at one end of the connecting rod 202 is clamped on the other straight rod, and the connecting rod 202 keeps the distance between the two straight rods unchanged.

[0036] Preferably, the anti-kicking assembly further comprises a detachable force unloading bag 203, the force unloading bag 203 comprises a force unloading portion 2031 and a connecting portion 2032, the connecting portion 2032 is cylindrical, and during milking operation, the force unloading bag 203 is suspended on the portions of the two limiting rods 201 located outside the main body 10, that is, it is suspended on the two limiting rods 201 through the cylindrical connecting portion 2032, and the force unloading bag 203 is detachably arranged on the two limiting rods 201. During non-milking operation, the force unloading bag 203 can be detached from the two limiting rods 201.

[0037] Preferably, the force unloading bag 203 is filled with fine sand or clean water.

[0038] Preferably, the anti-kicking device also includes a counterweight (not shown in the figure), for example, a stone or iron block, which is arranged in the main body 10 at the bottom of the riding surface to increase the weight of the anti-kicking device and prevent the anti-kicking device from moving due to the movement of the cow's hind legs.

[0039] Example 2

[0040] like Figure 4-Figure 5 As shown, as another implementation of the limit rod in the above-mentioned embodiment 1, the limit rod 201 in this solution adopts telescopic rods fixedly arranged on both sides of the length direction of the main body 10 instead of straight rods. In the aforementioned solution, the straight rods are opened by rotating and unfolding, while in this embodiment, they are unfolded by telescopic means. Specifically, the two limit rods 201 are both telescopic rods, which include an outer tube fixed to the outside of the main body 10 and an inner rod with a socket in the outer tube, and the inner rod can be inserted or pulled out along the circumference of the outer tube, wherein the two telescopic rods are fixedly arranged on the main body below the seating plane 101, and the telescopic directions of the telescopic parts of the two telescopic rods are the same.

[0041] It is unfolded by telescopic means, and there is no need to set a connecting rod between the two limit rods 201 (i.e., telescopic rods). When it is not in use, the force unloading bag 203 needs to be disassembled and separated from the telescopic rod. When in use, the force unloading bag 203 can be hung on the protruding part of the telescopic rod.

[0042] According to the disclosure and teaching of the above specification, those skilled in the art to which the utility model belongs can also make appropriate changes and modifications to the above implementation method. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
