DETAILED DESCRIPTION

[0012] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0013] See also Figure 1-6 The present invention provides a technical solution of a spermator for artificial insemination of pigs: Example

[0014] according to Figure 1 As shown, it includes a U-shaped handle frame 1, a horizontally retractable folding airbag 2 is arranged in the middle of the upper end of the U-shaped handle frame 1, and a valve body 3 and a semen discharge control mechanism 6 are respectively arranged at the front and rear ends of the folding airbag 2, and the semen discharge control mechanism 6 can control the contraction of the folding airbag 2 to press out the boar semen in the folding airbag 2, and the valve body 3 plays a role in controlling the semen discharge amount of the folding airbag 2, and the semen discharge control mechanism 6 can control the valve body 3 to start the operation while controlling the contraction of the folding airbag 2; the front end of the folding airbag 2 is connected to a semen discharge head 4 through the valve body 3, the front end of the semen discharge head 4 is connected to a sperm guide tube 5, and a rotating ring seat 33 is installed at the front end of the sperm guide tube 5, when artificial insemination of a sow, the rotating ring seat 33 is inserted into the sow's vagina, and then the folding airbag 2 is controlled to contract by the semen discharge control mechanism 6, and the semen in the folding airbag 2 passes through the semen discharge head 4 and the sperm guide tube 5 and is finally input into the sow's uterus through the rotating ring seat 33.

[0015] A hard cover 8 is symmetrically installed at the front and rear ends of the folding airbag 2. The hard cover 8 at the front end is used as a fine cover plate 31 of the valve body 3. Figure 3 and Figure 4As shown, the valve body 3 includes a sperm outlet cover plate 31, and a plurality of sperm outlet ports 1 32 are circumferentially formed on the sperm outlet cover plate 31. A sperm baffle plate 4 is arranged at the front end of the sperm outlet cover plate 31, and the sperm baffle plate 4 is fixed to the front upper end of the U-shaped handle frame 1 through a rotating ring seat 33. A rotating ring seat 33 is rotatably mounted between the sperm outlet cover plate 31 and the sperm baffle plate 4. The rotating ring seat 33 seals and connects the sperm outlet cover plate 31 and the sperm baffle plate 4 together. A sperm baffle plate 34 is arranged inside the rotating ring seat 33, and a sperm outlet port 2 35 corresponding to the position of the sperm outlet port 1 32 is arranged on the sperm baffle plate 34. When the rotating ring seat 33 rotates, the sperm outlet port 2 35 can correspond to the sperm outlet port 1 32 in sequence. When the semen outlet 2 35 rotates to a position corresponding to the semen outlet 1 32, the folded airbag 2 is connected to the semen outlet head 4, and the semen in the folded airbag 2 can enter the semen outlet head 4 through the aligned semen outlet 2 35 and the semen outlet 1 32 to realize the transportation of semen; when the semen outlet 2 35 rotates to a position not corresponding to the semen outlet 1 32, the rotating ring seat 33 can block the semen outlet 1 32, and the semen in the folded airbag 2 cannot flow out through the semen outlet 1 32; at the same time, the folded airbag 2 is continuously controlled and contracted by the semen outlet control mechanism 6, and at this time, the folded airbag 2 is in a state of accumulating force, so that when the semen outlet 2 35 is aligned with the next semen outlet 1 32 and has sufficient instantaneous impact force, the semen rushes out quickly; through the continuous rotation of the rotating ring seat 33, the folded airbag 2 is in a continuous cycle state of accumulating force-sperm-accumulating force-sperm-discharging, thereby increasing the impact force of semen during transportation.

[0016] A cross 9 is fixed in the sperm shielding plate 4, and a connecting column 10 is vertically fixed at the center of the cross 9. A through groove 36 is opened through the center of the rotating ring seat 33. The connecting column 10 movably passes through the through groove 36 and is connected to the center of the sperm outlet cover plate 31. The connecting column 10 and the cross 9 can ensure that when the rotating ring seat 33 rotates, the sperm outlet cover plate 31 and the sperm shielding plate 4 are connected together and remain motionless.

[0017] The specific structure of the sperm control mechanism 6 is as follows: Figure 2-5 As shown, it includes a screw 61 rotatably mounted on the rear side of the hard cover body 8, a nut 63 is threadedly mounted on the screw 61, and the nut 63 is fixedly mounted on the upper end of the rear side of the U-shaped handle frame 1, and a fixing seat 62 is fixedly installed at the front end of the screw 61. By controlling the rotation of the fixing seat 62, the screw 61 can be driven to follow the rotation, and then under the thread cooperation of the screw 61 and the nut 63, a thrust is applied to the rear end of the folding airbag 2 through the screw 61 to push the folding airbag 2 to shrink. The extrusion and shrinkage of the folding airbag 2 is achieved by rotating the screw 61, which is more labor-saving and easy to operate than directly extruding the folding airbag 2.

[0018] An L-shaped rotating rod 64 is fixed to the side wall of the rotating ring seat 33, and the fixed seat 62 and the rotating rod 64 are connected by a horizontally arranged connecting piece, so that the rotating ring seat 33 can rotate synchronously with the fixed seat 62 and the screw 61, thereby realizing the start-up operation of the valve body 3, and a turning handle 65 is fixedly sleeved on the end of the rotating rod 64, and the rotating ring seat 33 can be driven to rotate by turning the turning handle 65, and the synchronous rotation of the fixed seat 62 and the screw 61 can be realized by cooperating with the connecting piece; because the distance between the fixed seat 62 and the rotating ring seat 33 will change when the semen discharge control mechanism 6 controls the contraction of the folding airbag 2, the connecting piece can be set to a telescopic rod 66 with a telescopic effect, and the telescopic rod 66 is parallel to the fixed seat 62 and the two ends are respectively connected to the fixed seat 62 and the rotating rod 64.

[0019] like Figure 6 As shown, an annular groove 12 is provided on the outer side wall of the sperm outlet cover plate 31 and the sperm baffle plate 4, and flanges are provided inwardly at the front and rear ends of the rotating ring seat 33. The rotating ring seat 33 is inserted into the annular groove 12 through the flanges at both ends to achieve the connection between the sperm outlet cover plate 31 and the sperm baffle plate 4 and prevent the rotating ring seat 33 from falling off from between the sperm outlet cover plate 31 and the sperm baffle plate 4; an annular slide rail 11 is also provided on the outer side wall of the sperm outlet cover plate 31 and the sperm baffle plate 4 and the inner side wall of the rotating ring seat 33, and a plurality of ball bearings are distributed in the annular slide rail 11. The annular slide rail 11 and the ball bearings can improve the stability and smoothness of the rotating ring seat 33 during rotation.

[0020] A semen replenishing port 7 is provided on the hard cover body 8 at the rear end of the folding airbag 2 , through which semen can be replenished into the folding airbag 2 .

[0021] When used specifically, the insemination device for artificial insemination of pigs of the present invention first fills the folding airbag 2 with sufficient semen through the semen replenishment port 7, and then inserts the disposable insemination tube 13 into the vagina of the sow. Then, the operator holds the U-shaped handle frame 1 with one hand and rotates the handle 65 with the other hand, and drives the rotating ring seat 33 and the screw rod 61 to rotate synchronously through the cooperation of the rotating rod 64 and the telescopic rod 66. When the screw rod 61 rotates, the screw rod 61 can be driven to move forward through the thread cooperation effect between the screw rod 61 and the nut 63. When the screw rod 61 moves forward, it applies a thrust to the rear of the folding airbag 2, pushing the folding airbag 2 to contract, and the folding airbag 2 is squeezed to squeeze out the semen inside. When the rotating ring seat 33 rotates, the semen outlet 2 35 is aligned with each semen outlet 1 32 in sequence. When the semen outlet 2 35 rotates to a position corresponding to the semen outlet 1 32, the folded airbag 2 is connected to the semen outlet head 4, and the semen in the folded airbag 2 enters the semen outlet head 4 through the aligned semen outlet 2 35 and semen outlet 1 32, and is transported to the sow's uterus in cooperation with the sperm guide tube 5 and the disposable sperm deferens 13. When the semen outlet 2 35 rotates to a position not corresponding to the semen outlet 1 32, the rotating ring seat 33 blocks the semen outlet 1 32, and the semen in the folded airbag 2 cannot pass through the semen outlet. The semen flows out from the semen outlet 1 32, and at the same time, the folded airbag 2 is continuously controlled and contracted by the semen outlet control mechanism 6, so that the folded airbag 2 is in a state of storing power. When the semen outlet 2 35 rotates to a position aligned with the next semen outlet 1 32, the folded airbag 2 in the state of storing power can quickly squeeze out the internal semen. The semen outlet control mechanism 6 continuously squeezes the folded airbag 2, and cooperates with the continuous rotation of the rotating ring seat 33, so that the folded airbag 2 is in a continuous cycle state of storing power-sperm-sperm-sperm-sperm, thereby improving the impact force of semen during transportation, thereby improving the efficiency and effect of artificial insemination. Example

[0022] On the basis of Example 1, the similarities between this embodiment and Example 1 are not repeated here, and the differences are as follows: matching threads can be set on the inner side of the hard cover body 8 and the outer side of the extension section of the folding airbag 2, and the hard cover body 8 can be detachably installed on the front and rear ends of the folding airbag 2 by means of threads, and then the semen discharge control mechanism 6 and the valve body 3 can be detachably connected to the front and rear ends of the folding airbag 2, so as to facilitate the removal of the folding airbag 2 for cleaning or replacement.
