[0057] The exemplary embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present invention, and are not intended to exhaust all possible modes of the present invention, nor to limit the scope of the present invention.

[0058] Taking the prevention of sheep as an example, the livestock prevention device according to the present invention (hereinafter referred to as the prevention device) is introduced. The prevention device according to the present invention can keep the sheep in a predetermined position, automatically mark and / or identify the sheep's identity (hereinafter also referred to as the identity mark), and can vaccinate the sheep.

[0059] Unless otherwise specified, the present invention Figure 1 The coordinate system shown in FIG. 1 is used to illustrate the positional relationship of each component, the first direction Y extends along the front-back direction of the sheep, and the second direction X extends along the left-right direction of the sheep. It should be understood that the positional relationship defined by the first direction Y and the second direction X in the present invention is relative, and the coordinate axis can be rotated in space according to the actual application of the device.

[0060] Figure 1 and Figure 2 1 is a schematic diagram of a livestock epidemic prevention device according to an embodiment of the present invention. The livestock epidemic prevention device in this embodiment includes a trolley 1 and an aisle fence 12.

[0061] The bottom of the trolley 1 is provided with wheels 15 for easy movement, and the trolley 1 can be moved to the sheep breeding ground according to the location. At the same time, a plurality of fixing columns 16 are arranged around the trolley 1. By adjusting the installation height of the trolley 1 relative to the fixing columns 16, the wheels 15 of the trolley 1 can be lifted off the ground, so that the trolley 1 is not easily moved relative to the ground (usually the wheels 15 are lifted off the ground during the vaccination process).

[0062] The trolley 1 has foot pedals 17 inclined relative to the horizontal direction at both the front and rear ends in the first direction Y. The foot pedals 17 are connected to the bottom plane inside the trolley and extend to the ground outside the trolley, so as to facilitate the sheep to enter and exit the trolley 1 of the epidemic prevention device. In the vertical direction, the lowest position of the foot pedals 17 is not lower than the lowest position of the wheels 16, so as to facilitate the movement of the trolley 1.

[0063] The trolley 1 comprises a frame 11 on which are arranged mechanisms such as a conveying line 2, a blocking mechanism 3, a neck pressing mechanism 4, an injection mechanism 5, a chip implanting mechanism 6 and a chip scanning mechanism 7.

[0064] The front and rear ends of the trolley 1 in the first direction Y are open, and the rear end of the trolley 1 is connected to the aisle fence 12.

[0065] One end of the aisle fence 12 is connected to the conveyor line 2 of the epidemic prevention device, and the other end can be connected to the sheepfold, so that the sheep can enter the conveyor line 2 from the sheepfold in turn to wait and be epidemic prevention. The width of the aisle fence 12 is only enough for one sheep to pass through, so as to avoid multiple sheep arranging in parallel at the entrance of the conveyor line 2 and causing blockage. The aisle fence 12 includes multiple groups of detachably connected fence sections 121, which is not only convenient for disassembly, storage, transportation and assembly of the aisle fence 12, but also convenient for adjusting the length and direction of the aisle formed by the aisle fence 12.

[0066] The overall epidemic prevention process of the epidemic prevention device according to one embodiment of the present invention includes: first, the sheep enters the conveyor line 2 from the aisle fence 12, and the conveyor line 2 carries the sheep forward. Then, when the sheep moves to a certain position (when it hits the blocking mechanism 3), the sensor 13 detects a signal, the conveyor line 2 stops running, and the chip scanning mechanism 7 extends and scans whether there is a chip on the sheep's neck. If there is a chip, the chip information will be stored in the computer, and the chip will not be implanted; if there is no chip, a chip needs to be implanted. Then, the chip scanning mechanism 7 is reset, and the neck pressing mechanism 4 is pressed down and clamps the sheep's neck together with the blocking mechanism 3. After the sheep's neck is fixed, the injection mechanism 5 performs the action of injecting the medicine, and at the same time, the chip implanting mechanism 6 performs the action of implanting the chip according to the situation. Finally, the injection mechanism 5, the chip implanting mechanism 6 and the neck pressing mechanism 4 are reset, the blocking mechanism 3 is opened, and the conveyor line 2 is started, so that the sheep that have received epidemic prevention leave. After the front sensor 13 detects the signal that the sheep has completely left, the blocking mechanism 3 is closed again, and the next sheep is started for epidemic prevention.

[0067] According to the following Figures 3 to 6 , introduces a conveying line 2, a blocking mechanism 3 and a neck pressing mechanism 4 of an epidemic prevention device according to an embodiment of the present invention.

[0068] The conveyor line 2 includes a front conveyor line 2a and a rear conveyor line 2b. The front end of the front conveyor line 2a forms an outlet, and the rear end of the rear conveyor line 2b forms an entrance. The two conveyor lines can transport sheep at the same time. The sheep on the rear conveyor line 2b wait while the sheep on the front conveyor line 2a are undergoing epidemic prevention. That is, the conveyor line 2b is equivalent to a waiting area. The setting of the waiting area eliminates unnecessary time waste between various links of the epidemic prevention operation, saves time in the entire epidemic prevention process, and makes the epidemic prevention process more efficient.

[0069] Each section of the conveyor line 2 includes two conveyor belts 21 symmetrically arranged on both sides of the sheep body, and a V-shaped transport channel with a larger upper part and a smaller lower part is formed between the two conveyor belts 21, which is convenient for fitting the sheep body to lift the sheep body and transport it. The two conveyor belts of the rear section conveyor line 2b are folded at the entrance to the side away from the sheep body to form a trumpet-shaped entrance of the conveyor line 2, which is convenient for guiding the sheep into the transport channel.

[0070] Preferably, refer to Figure 6 , the minimum distance L between the two conveyor belts 21 is not greater than 250 mm, and the acute angle M between the two conveyor belts 21 is 15° to 25°, so as to better fit the sheep's body and better limit the sheep's body. More preferably, the minimum distance L between the two conveyor belts 21 is 200 mm to 250 mm, which is more suitable for the actual shape of the sheep's body.

[0071] In this embodiment, the angle and the minimum distance between the two conveyor belts 21 can be adjusted according to actual conditions. Figure 6 In this embodiment, the two conveyor belts 21 are connected to the frame 11 through a first connection portion 111 and a second connection portion 112. The first connection portion 111 can reciprocate relative to the frame 11 in the second direction X, and the first connection portion 111 enables the conveyor belt 21 to be rotatably connected to the frame 11. The second connection portion 112 can reciprocate relative to the frame 11 in the vertical direction, and the second connection portion 112 enables the conveyor belt 21 to be rotatably connected to the frame 11, so that the minimum distance L and the acute angle M between the two conveyor belts 21 can be adjusted.

[0072] It should be understood that the minimum distance L and the acute angle M between the two relative conveyor belts 21 of the epidemic prevention device according to the present invention can be adjusted, and are not limited to the above-mentioned manner. For example, in the case where the angle between the conveyor belt 21 and the frame 11 can be controlled, only the first connection part 111 can be provided without the second connection part 112; or, in the case where the angle between the conveyor belt 21 and the frame 11 can be controlled, only the second connection part 112 can be provided without the first connection part 111. For another example, the first connection part 111 can be arranged to reciprocate relative to the frame 11 in the second direction X, or can be arranged to be fixed relative to the frame 11. The former can adjust the minimum distance L and the acute angle M, and the latter can only adjust the acute angle M. For another example, one of the two conveyor belts 21 can be fixed, and the other can be adjustable.

[0073] It should be understood that when the sheep is clamped by the two conveyor belts 21, the sheep's legs leave the ground. In this state, the sheep is difficult to struggle greatly, which provides a good foundation for subsequent epidemic prevention operations. Therefore, the conveyor line 2 not only plays the role of conveying the sheep along the first direction Y, but also plays the role of fixing the sheep at the location of the epidemic prevention operation.

[0074] Next, two other mechanisms that play a role in fixing the sheep, namely the blocking mechanism 3 and the neck pressing mechanism 4, are introduced.

[0075] Reference Figure 5 The blocking mechanism 3 is arranged at the exit of the transport channel formed by the conveyor line 2, and the blocking part 31 of the blocking mechanism 3 can be opened or closed, and is used to control the sheep on the conveyor line 2 to remain at the exit or to leave the transport channel from the front. Specifically, in the present embodiment, the blocking part 31 is hinged on the frame 11 on the exit side of the transport channel, and the blocking part 31 is also connected to the blocking cylinder 32 at the non-hinged part. One end of the blocking cylinder 32 is fixed on the frame 11 (not shown in the figure), and the other end can be retracted to drive the blocking part 31 to rotate around the hinged side to block the exit of the conveyor line 2. The blocking part 31 of the blocking mechanism 3 in the closed state contacts the front neck of the sheep, and is used as the lower reference for the neck clamping mechanism 4 to clamp the neck. The upper side of the blocking part 31 protrudes toward the front of the transport channel relative to the lower side to adapt to the shape of the sheep's neck. The part where the blocking part 31 contacts the sheep is wrapped with a flexible material to avoid causing harm to the sheep.

[0076] The neck pressing mechanism 4 is arranged above the exit of the transport channel formed by the conveyor line 2, and the neck pressing mechanism 4 includes a neck pressing part 41, a clamping cylinder 42 and a shaft 43. After the blocking mechanism 3 blocks the sheep, the neck pressing part 41 can be pressed against the back of the sheep's neck, thereby fixing the neck of the sheep together with the blocking mechanism 3. Specifically, in this embodiment, the neck pressing part 41 of the neck pressing mechanism 4 is fixedly connected to the shaft 43 and can rotate with the shaft 43. The shaft 43 is arranged on the frame 11 (not shown in the figure) above the exit of the conveyor line 2. The middle part of the shaft 43 is also provided with a rotating arm 430 extending radially along the shaft 43. The radial outer side of the rotating arm 430 is connected to the clamping cylinder 42, and the other end of the clamping cylinder 42 is fixed on the frame 11 (not shown in the figure). When the clamping cylinder 42 is active, it can drive the shaft 43 to rotate, so that the shaft 43 drives the neck pressing part 41 to rotate so that the neck pressing part 41 is pressed against the back of the sheep's neck. The neck pressing part 41 uses a flexible material to contact the sheep to avoid causing harm to the sheep.

[0077] In this embodiment, a sensor is also provided to detect the position of the sheep in the epidemic prevention device. Specifically, a front section sensor 13 (see Figure 2 ). The front sensor 13 is an infrared sensor. Specifically, the detection position of the front sensor 13 is approximately located at the position where the blocking part 31 in the closed state contacts the front neck of the sheep. When the front sensor 13 detects that the sheep has entered (that is, when the front neck of the sheep contacts the blocking part 31), the conveyor belt 21 of the front conveyor line 2a stops running, so that the sheep can receive epidemic prevention in place; after the epidemic prevention is completed, the front sensor 13 detects that the sheep has completely left, and the blocking mechanism 3 closes and waits for the next sheep to be blocked.

[0078] A rear sensor 14 is also provided between the rear conveyor line 2b and the front conveyor line 2a (see Figure 1 ). The rear sensor 14 is an infrared sensor. The height of the detection position of the rear sensor 14 is roughly the same as that of the front sensor 13. The rear sensor 14 is used to detect the position of the sheep on the rear conveyor line 2b. When the rear sensor 14 detects that the sheep has completely entered the rear conveyor line 2b, the conveyor belt 21 of the rear conveyor line 2b stops running, so that the sheep on the rear conveyor line 2b wait in place for the sheep on the front conveyor line 2a to receive epidemic prevention.

[0079] According to the following Figure 7 and Figure 8 The injection mechanism 5, chip implantation mechanism 6 and chip scanning mechanism 7 of the epidemic prevention device according to one embodiment of the present invention are introduced. The injection mechanism 5 is used to inject the vaccine for epidemic prevention into the sheep at the side of the sheep's neck. The chip implantation mechanism 6 is used to implant a chip recording the sheep's identity information into the sheep at the side of the sheep's neck. The chip scanning mechanism 7 is used to scan and identify whether a chip has been implanted at the chip pre-implantation position on the side of the sheep's neck, thereby determining whether the chip implantation mechanism 6 is working.

[0080] Figure 7 It is a schematic diagram of the injection mechanism 5, chip implantation mechanism 6, chip scanning mechanism 7, blocking mechanism 3 and neck pressing mechanism 4 on a partial frame 11 according to the present invention. The blocking mechanism 3 and the neck pressing mechanism 4 fix the sheep's neck, which determines the position for the subsequent vaccination and chip implantation of the sheep, that is, the side of the predetermined clamping position of the sheep's neck is the position for vaccination and chip implantation. The injection mechanism 5, chip implantation mechanism 6 and chip scanning mechanism 7 are arranged on the side of the predetermined clamping position of the sheep's neck. In this embodiment, the injection mechanism 5, chip implantation mechanism 6 and chip scanning mechanism 7 are all arranged on the frame 11 outside the exit of the transport channel. Among them, the chip implantation mechanism 6 and the chip scanning mechanism 7 are arranged on the same side frame 11, and the injection mechanism 5 is arranged on the other side frame 11.

[0081] Figure 8 FIG. 1 is a schematic diagram of a chip scanning mechanism 7 in a working state according to an embodiment of the present invention. The chip scanning mechanism 7 is arranged on the upper side of the blocking mechanism 3 (refer to FIG. 1 ). Figure 7 ), when it is working, the chip scanning mechanism 7 will be driven by the cylinder to move downward and toward the sheep neck (moving to Figure 8 ), thereby contacting the sheep's neck for chip scanning.

[0082] According to the following Fig. 9 and Fig.10 The specific structure of the injection mechanism 5 of the epidemic prevention device according to one embodiment of the present invention is introduced.

[0083] In this embodiment, the injection mechanism 5 is arranged on the frame 11 (not shown) on both sides outside the outlet of the transport channel, and the injection mechanism 5 includes a needle-free syringe 51 and a drug suction mechanism 52. It should be understood that the needle-free injection referred to here means that the injection needle 511 does not need to be inserted under the skin of the cow.

[0084] The medicine suction mechanism 52 includes a medicine suction needle 521 and a medicine bottle 522 containing medicine. The medicine suction needle 521 is driven by the medicine suction cylinder 523 above it to enter the medicine bottle 522, and the tail of the medicine suction needle 521 is connected to the needle-free syringe 51 through a hose, so that the medicine in the medicine bottle 522 can be provided to the needle-free syringe 51. When the medicine bottle 522 needs to be replaced, the medicine suction cylinder 523 retracts to take the medicine suction needle 521 out of the medicine bottle 522.

[0085] The needle-free syringe 51 cooperates with the extension cylinder 53 and the trigger cylinder 54 to realize an automatic injection process according to a predetermined program.

[0086] Specifically, in this embodiment, the main body of the needle-free syringe 51 is fixed on the connecting plate 55, and an injection buffer plate 56 is arranged in front of the injection direction of the injection needle 511 of the needle-free syringe 51. The injection buffer plate 56 is connected to the connecting plate 55 through a spring 57. The injection buffer plate 56 has a through hole for the injection needle 511 to pass through for injection.

[0087] One side of the extension cylinder 53 is fixed to the frame 11 (not shown in the figure), and the other side is connected to the connecting plate 55, so that the extension and contraction of the extension cylinder 53 can drive the needle-free syringe 51 and the injection buffer plate 56 to approach or move away from the sheep's neck. When the injection buffer plate 56 approaches and contacts the sheep's neck, the spring 57 is compressed, so that the injection needle 511 is pressed against the epidermis on the side of the sheep's neck through the through hole on the injection buffer plate 56. The injection buffer plate 56 contacts the neck of the livestock before the injection needle 511, and applies pressure to the neck of the livestock through the spring 57, which is convenient for subsequent injection.

[0088] The main body of the trigger cylinder 54 is fixed relative to the main body of the needle-free syringe 51, and the piston of the trigger cylinder 54 extends to the front of the trigger of the needle-free syringe 51. The piston of the trigger cylinder 54 has a protrusion 541. The protrusion 541 can pull the trigger of the needle-free syringe 51 when the trigger cylinder 54 is retracted, so that the needle-free syringe 51 can absorb the medicine and inject it into the subcutaneous part of the sheep to complete the vaccine injection.

[0089] According to the following Fig.11 The specific structure of the chip scanning mechanism 7 of the epidemic prevention device according to one embodiment of the present invention is introduced.

[0090] The chip scanning mechanism 7 includes a chip scanning unit 71, a first scanning cylinder 72 and a second scanning cylinder 73. The first scanning cylinder 72 can drive the chip scanning unit 71 to reciprocate in the vertical direction, and the second scanning cylinder 73 can drive the chip scanning unit 71 to reciprocate in the second direction X, so that the chip scanning unit 71 can be attached to a predetermined clamping position on the neck of the sheep to perform chip scanning and read chip information.

[0091] In this embodiment, in order to prevent the chip scanning mechanism 7 from interfering with the neck pressing mechanism 4 near the sheep's neck, when the sheep on the conveyor line 2 contacts the blocking mechanism 3 and stops moving forward (indicating that the sheep has arrived), the chip scanning mechanism 7 starts to stick to the sheep's neck before the neck pressing mechanism 4 and performs chip scanning (at this time, the neck pressing mechanism 4 does not clamp the sheep). After the chip scanning mechanism 7 completes the chip scanning, the chip scanning mechanism 7 is driven by the cylinder to return to the upper side of the blocking mechanism 3, and then the neck pressing mechanism 4 starts to work, and the neck pressing mechanism 4 and the blocking mechanism 3 clamp the sheep together to prepare for vaccine injection and chip implantation.

[0092] According to the following Figures 12 to 18 , introduces the specific structure of the chip implanting mechanism 6 of the epidemic prevention device according to an embodiment of the present invention.

[0093] Fig.12 The chip assembly 60 used in this embodiment has a specific structure. The chip assembly 60 includes a needle assembly 601 and a syringe assembly 605 .

[0094] The needle assembly 601 includes a needle 602 and a needle sleeve 603 sleeved on the outside of the needle 602. The needle 602 has a hollow needle tube 604, and the chip is accommodated inside the needle tube 604. The end of the needle 602 away from the needle tube 604 also has an internal thread, which can be connected to the syringe assembly 605 by threading.

[0095] The syringe assembly 605 includes a syringe 606, a push rod 607 and a return spring 608. One end of the syringe 606 can be threadedly connected to the needle 602. The push rod 607 can pass through the other end of the syringe 606 and enter the needle 602, thereby pushing the chip out of the needle tube 603. The return spring 608 is sleeved on the push rod 607 and can reset the push rod 607 after the chip is pushed out.

[0096] Reference Fig.13 The chip implanting mechanism 6 includes a chip changing module 6A and a chip implanting module 6B.

[0097] According to the following Figures 14 to 16 The chip changing module 6A according to one embodiment of the present invention is introduced. The chip changing module 6A is used to replace the needle assembly 601 of the chip assembly 60 and pull out the needle sleeve 603. The chip changing module 6A includes a material storage channel 61, a material receiving plate 62, a needle clamping claw 63 and a needle sleeve clamping claw 64.

[0098] The upper and lower ends of the storage channel 61 are open to store multiple needle assemblies 601 in the vertical direction. The receiving plate 62 is arranged below the storage channel 61 (refer to Fig.14 ), the needle assembly 601 at the bottom of the storage channel 61 can fall onto the receiving plate 62 by gravity.

[0099] The receiving plate 62 has a groove for accommodating the needle assembly 601. The receiving plate 62 can move below the storage channel 61 to push the needle assembly 601 out from below the storage channel (refer to Fig.15 Specifically, the receiving plate 62 is driven by the material dividing cylinder 621 , and the piston of the material dividing cylinder 621 can reciprocate in the first direction Y, thereby realizing the reciprocating movement of the receiving plate 62 below the material storage channel 61 .

[0100] The needle clamping jaw 63 can clamp the needle 602 of the needle assembly 601 on the material receiving plate 62, thereby moving the needle assembly 601. Specifically, the needle clamping jaw 63 is driven by the first translation cylinder 631, the second translation cylinder 632, and the lifting cylinder 633. The piston of the first translation cylinder 631 can reciprocate in the first direction Y, the piston of the second translation cylinder 632 can reciprocate in the second direction X, and the piston of the lifting cylinder 633 can reciprocate in the vertical direction, thereby realizing the reciprocating movement of the needle clamping jaw 63 in three dimensions: the first direction Y, the second direction X, and the vertical direction.

[0101] The needle sleeve clamping jaw 64 is arranged above the needle clamping jaw 63. The needle clamping jaw 63 can move the clamped needle assembly 601 to the needle sleeve clamping jaw 64. The needle sleeve clamping jaw 64 can clamp the needle sleeve 603 of the needle assembly 601 and pull out the needle sleeve 603 (refer to Fig.16 Specifically, the needle sleeve clamping jaw 64 is driven by the needle sleeve pushing cylinder 641, and the piston of the needle sleeve pushing cylinder 641 can reciprocate in the second direction X. The piston of the needle sleeve pushing cylinder 641 is pushed out, thereby driving the needle sleeve clamping jaw 64 to pull the needle sleeve 603 off the needle head 602.

[0102] According to the following Figure 17 to Figure 18 The chip implantation module 6B according to one embodiment of the present invention is introduced. The chip implantation module 6B is used to connect the needle 602 to the syringe assembly 605 and implant the chip in the needle 602 into the sheep. The chip implantation module 6B includes a connecting plate 65, a tightening motor 66 and a chip implantation cylinder 67.

[0103] One end of the connecting plate 65 has a buffer plate 651 , and the buffer plate 651 has a through hole for the needle 602 to extend out.

[0104] The connecting plate 65 is connected to the piston of the pushing cylinder 654 , and the piston of the pushing cylinder 654 can reciprocate in the second direction X, so as to press the buffer plate 651 of the connecting plate 65 against a predetermined clamping position of the sheep's neck.

[0105] The middle part of the connecting plate 65 has an L-shaped moving plate 652, and the syringe assembly 605 is arranged on the moving plate 652 of the connecting plate 65. The moving plate 652 can reciprocate relative to the connecting plate 65 in the second direction X, so as to approach or move away from the buffer plate 651. The moving plate 652 also has a limit block 653 (refer to Fig.18 ), the limit block 653 can limit the minimum distance between the movable plate 652 and the buffer plate 651, so that the needle 602 on the movable plate 652 can be inserted just under the sheep's skin and remain motionless.

[0106] The needle clamping jaw 63 can move the needle 602 to the front of the syringe assembly 605. The needle clamping jaw 63 is also connected to the piston of the needle pressing cylinder 634, and the needle pressing cylinder 634 can drive the needle clamping jaw 63 to press the needle 602 on the needle clamping jaw 63 onto the syringe assembly 605 on the moving plate 652.

[0107] The syringe assembly 605 can be driven by the tightening motor 66 and rotate around its own central axis on the moving plate 651, so that the syringe assembly 605 and the needle 602 close together can be tightened together.

[0108] The ejector rod 607 of the syringe assembly 605 is connected to the chip implanting cylinder 67 , and the piston of the chip implanting cylinder 67 can reciprocate in the second direction X, so that the ejector rod 607 ejects the chip in the needle tube 604 .

[0109] Specifically, refer to Fig.18 The chip implantation cylinder 67 is connected to the top head 671, and a spring 672 is sleeved on the top head 671. The L-shaped movable plate 652 has a through hole, which only allows the top head 671 to pass through, but does not allow the spring 672 to pass through. Therefore, the top head 671 is connected to the ejector rod 607 through the through hole, and one end of the spring 672 presses against the protrusion of the top head 671, and the other end presses against the movable plate 652.

[0110] When the piston of the chip implanting cylinder 67 extends out, the movable plate 652 is pushed, so that the needle 602 of the chip assembly 60 on the movable plate 652 passes through the through hole on the buffer plate 651 and enters the subcutaneous tissue of the sheep's neck (during the movement of the movable plate 652, the spring 672 hardly deforms); at this time, the movable plate 652 is limited by the limit block 653 and no longer moves, the piston of the chip implanting cylinder 67 continues to extend, the spring 672 is compressed, and the top head 671 continues to move relative to the movable plate 652, and the top head 671 pushes the push rod 607, so that the chip in the needle tube 604 is ejected and enters the subcutaneous tissue of the sheep's neck; finally, the piston of the chip implanting cylinder 67 retracts, the reset spring 608 and the spring 672 are reset, and the piston of the chip implanting cylinder 67 pulls the movable plate 652 back to its original position through the protrusion on the other side of the push rod 671.

[0111] The working process of the chip implanting mechanism 6 is as follows: the receiving plate 62 removes the needle assembly 601 at the bottom of the storage channel 61, then the needle clamping claw 63 clamps the needle 602 of the needle assembly 601, and the needle sleeve clamping claw 64 clamps the needle sleeve 603 of the needle assembly 601, and separates the needle sleeve 603 from the needle 602. The needle clamping claw 63 presses the needle 602 against the front of the syringe assembly 605, and the syringe assembly 605 and the needle 602 are screwed together by the tightening motor 66. Then, the buffer plate 651 of the connecting plate 65 presses against the neck of the sheep, and the chip implanting cylinder 67 extends to implant the chip of the chip assembly 60 into the sheep.

[0112] The present invention has at least one of the following advantages:

[0113] (i) The sheep are transported and clamped by the conveyor line 2. Since the sheep's feet are suspended in the air when clamped by the conveyor line 2, the sheep cannot struggle hard, so that the epidemic prevention operation can be carried out smoothly and reliably.

[0114] (ii) The epidemic prevention device of the present invention is easy to move and fix, and can be connected to a place where the livestock are kept, so as to be adaptable to different epidemic prevention environments.

[0115] (iii) The epidemic prevention device of the present invention includes, in addition to the forced fixation device, an injection mechanism 5, a chip implantation mechanism 6 and a chip scanning mechanism 7, etc., which can automatically complete epidemic prevention operations such as forced fixation, vaccine injection, chip scanning and / or implantation of livestock, eliminating manual labor and having high safety.

[0116] Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art can make various modifications to the above-mentioned embodiments of the present invention under the guidance of the present invention without departing from the scope of the present invention. For example:

[0117] (i) The conveyor line 2 according to the present invention is not limited to two sections, the front section conveyor line 2a and the rear section conveyor line 2b, and can be a multi-section conveyor line as required.

[0118] (ii) The front sensor 13 and the rear sensor 14 of the epidemic prevention device according to the present invention are not limited to infrared sensors, and only need to be able to detect whether the livestock has reached the predetermined position, so the type of sensor can be changed as needed. For example, the front sensor 13 can be set as a force sensor on the blocking mechanism 13. When the force sensor detects force, that is, the livestock contacts the blocking mechanism 13, it means that the livestock has reached the position, and its effect is the same as that of the infrared sensor.
