Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary equipment for sow insemination, and in particular relates to a back pressing device for insemination. Background Art

[0002] During the artificial insemination process of sows, in order to improve the mating effect, workers are usually required to press the back of the sows to simulate the movements of boars during mating, increase the excitement of the sows, and then increase the conception rate and litter size of the sows. However, the number of sows in existing pig farms has become large-scale, and it is obviously unlikely that each worker will be responsible for the insemination and back pressing of each sow. Therefore, at present, sow breeding workers usually tie a massager on the back of the sow to simulate boar mating, or use existing insemination devices for assistance. For example, a Chinese patent discloses a simple pig automatic insemination device (patent announcement number: CN202892146U), which simulates boar mating through a back pressure belt and a vibrator arranged on the back pressure belt to achieve the effect of stimulating the sows;

[0003] Although the above technical solution can realize automatic back compression of sows, the effect of stimulating the sow only by the vibrator set on the back compression belt is not as good as the manual effect of the staff, because manual back compression simulates the mating action of the boar, and the vibration emitted by the vibrator is not similar to the back compression of the staff, not to mention the simulation of the mating action of the boar. The vibration emitted by the vibrator is far less effective than manual pressing, and continuous vibration will also have a certain stimulating effect on the sow. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a semen insemination back pressing device to solve the problem that the existing sow back pressing device cannot well simulate the action of the boar during mating and the stimulation to the sow is not ideal.

[0005] In order to achieve the above object, the utility model provides the following technical solutions:

[0006] A back-pressing device for insemination comprises a fixed plate placed on the back of a pig and a protective shell arranged on the upper surface of the fixed plate, the fixed plate being arc-shaped, and having a first movable part and a second movable part hingedly connected at both ends of the fixed plate respectively; the first movable part and the second movable part are arranged from the back of the pig toward the navel, and the first movable part and the second movable part comprise a plurality of movable blocks hinged to each other; a connecting part is arranged between the free ends of the first movable part and the second movable part, the connecting part adopts a detachable connection mode, and under the action of the connecting part, the surface of each movable block is in close contact with the surface of the pig's skin; a plurality of air bags are arranged on the surface of each movable block close to the pig's side, and the air bags on the surface of each movable block are arranged at intervals along the length direction of the movable block; an air vent is opened on the surface of each air bag; a plurality of the air bags are commonly connected to an air pump, the air pump is arranged in the protective shell, and the air pump is electrically connected to a control unit also arranged in the protective shell.

[0007] Furthermore, each movable block is arc-shaped, and the curvature of each movable block is similar to the part that fits the surface of the pig skin.

[0008] Furthermore, the size of the airbag on the surface of each movable block gradually decreases from the pig's back toward the navel.

[0009] Furthermore, the surfaces of the fixed plate and each movable block close to the pig are covered with a heating layer, and the outer side of the heating layer is covered with a flexible buffer layer.

[0010] Furthermore, a handle is fixedly connected to the top of the protective shell.

[0011] The beneficial effects of the utility model are:

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] like Figure 1-2 As shown, the utility model provides a technical solution: a semen transfusion back pressing device, comprising a fixing plate 1 placed on the pig's back and a protective shell 2 arranged on the upper surface of the fixing plate 1, the fixing plate 1 is arc-shaped, and its curvature is similar to the curvature of the pig's back, and the two ends of the fixing plate 1 are respectively hinged with a first movable part and a second movable part; the first movable part and the second movable part are arranged from the pig's back toward the navel, and the first movable part and the second movable part include a plurality of mutually hinged movable blocks 3, in this solution, the first movable part and the second movable part are respectively hinged to form two mutually hinged movable blocks 3; a connecting part is provided between the free ends of the first movable part and the second movable part, and the connecting part adopts a detachable connection method, in this solution, the connecting part adopts a belt buckle 5 and a connecting belt 4, and when the connecting belt 4 and the belt buckle 5 are locked, the surface of the fixing plate 1 and each movable block 3 All of them are close to the surface of the pig skin; the surface of each movable block 3 close to the pig side is provided with multiple grooves (the grooves are not drawn in the figure), and an airbag 6 is arranged in each groove, and the multiple airbags 6 on the surface of each movable block 3 are arranged at intervals along the length direction of the movable block 3; each of the airbags 6 is provided with an air leakage hole (not drawn in the figure), and the air leakage speed of the air leakage hole is lower than the inflation speed of the airbag 6 by the air pump; the multiple airbags 6 are connected to an air pump for inflation through a connecting pipe, and an electromagnetic valve is provided on the connecting pipe between the air pump and each airbag 6, the air pump is arranged in the protective shell 2, and the air pump is electrically connected to a control unit also arranged in the protective shell 2, the control unit can adopt a single-chip microcomputer or an intelligent processor, and the control unit is electrically connected to each electromagnetic valve (the air pump, the electromagnetic valve and the control unit are all arranged in the protective shell 2 and are not shown).

[0020] Combination Figure 1 and Figure 2As shown, when the sow is pressed on the back, the fixing plate 1 is placed on the sow's back and close to the buttocks, and then the connecting belt 4 and the belt buckle 5 are fixed and locked, so that the fixing plate 1 and the multiple movable blocks 3 are all in close contact with the surface of the sow's skin, and the control unit is started. Through the preset program pre-stored in the control unit, the control unit controls the air pump and the corresponding solenoid valve to start working, and the air pump injects external air into the air bag 6 connected to it. The inflation speed is greater than the speed at which the air flows out of the air vent, so that the corresponding air bag 6 will bulge toward the sow's skin after being inflated for a period of time. After bulging for a period of time, the control unit controls the solenoid valve again to disconnect the connection between the air bag 6 and the air pump. At this time, since there is no air pump to inflate, and the surface of the air bag 6 is in close contact with the surface of the sow's skin, the gas in the air bag 6 will flow out from the air vent, and the air bag 6 will gradually deflate and shrink. When the airbag 6 is deflated for a period of time, it will return to its original state. At this time, the control unit controls the electromagnetic valve again and opens the connection between the airbag 6 and the air pump. The air pump inflates it again, causing the airbag 6 to expand. The above process is repeated in this way, so that the airbag 6 cycles back and forth between the expansion and contraction states, thereby achieving massage stimulation for the sow. Since each movable block 3 is provided with multiple airbags 6, the control unit controls the opening and closing of different electromagnetic valves, so that multiple airbags 6 repeat the above process at the same time and massage and stimulate the sow, further simulating the stimulation of multiple parts of the sow during mating by boars, which can effectively improve the fertilization rate and litter size of the sow and improve work efficiency. Moreover, since the first movable part and the second movable part are both composed of multiple movable blocks 3, the insemination back pressure device can be applicable to sows of different sizes within a certain range, thereby improving the scope of application.

[0021] In this embodiment, each of the movable blocks 3 is arc-shaped, and the curvature of each movable block 3 is similar to the part that fits the surface of the pig skin.

[0022] Each movable block 3 is set to a different curvature to fit the skin curve of the corresponding part of the sow, which can increase the contact area between the movable block 3 and the sow's skin surface, improve the stability of the device when fixed, and increase the stimulation of the airbag 6 to the sow's skin.

[0023] In this embodiment, the size of the airbag 6 on the surface of each movable block 3 gradually decreases from the pig's back toward the navel.

[0024] The closer to the navel, the smaller the arc of the massage stimulation of the airbag 6 is, further simulating the arc of the movement when the two front paws of the boar lie on the back of the sow during mating, which is more in line with the normal mating action of the boar.

[0025] In this embodiment, the surfaces of the fixed plate 1 and each movable block 3 close to the pig are covered with a heating layer, and the outer side of the heating layer is covered with a flexible buffer layer, which can be made of sponge, natural latex and other materials.

[0026] When the weather is cold, the heating layer can be used to preheat the surfaces of the fixed plate 1 and the movable block 3 to prevent their surfaces from touching the sow's skin surface when they are cold, thereby stimulating the sow and making her emotionally uneasy, which is not conducive to mating. The flexible buffer layer can improve the comfort of the fixed plate 1 and the movable block 3 when they touch the sow's skin surface.

[0027] In this embodiment, a handle 7 is fixedly connected to the top of the protective shell 2 to facilitate staff to take the device.

[0028] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
