Detailed Description

Exemplary embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the detailed description is intended only to teach one skilled in the art how to practice the invention, and is not intended to be exhaustive or to limit the scope of the invention.

Taking sheep epidemic prevention as an example, the epidemic prevention device for livestock (hereinafter referred to as epidemic prevention device) according to the invention is introduced. The epidemic prevention device can keep the sheep at a preset position, automatically realize the marking and/or identification of the sheep identity (hereinafter also referred to as identity identification for short), and inject vaccine into the sheep.

Unless otherwise specified, the present invention describes the positional relationship of the components in a coordinate system as shown in fig. 1, in which a first direction Y extends in the front-rear direction of the sheep and a second direction X extends in the left-right direction of the sheep. It should be understood that the positional relationship defined in the present invention according to the first direction Y and the second direction X is relative, and the coordinate axes can be spatially rotated according to the practical application of the apparatus.

Fig. 1 and 2 are schematic views of an animal epidemic prevention apparatus according to an embodiment of the present invention, which includes a trolley 1 and a gangway fence 12.

The wheels 15 are arranged at the bottom of the trolley 1, so that the trolley is convenient to move, and the trolley 1 can be conveniently moved to a sheep raising field. Meanwhile, a plurality of fixed columns 16 are arranged around the trolley 1, and the wheels 15 of the trolley 1 can be separated from the ground by adjusting the mounting height of the trolley 1 relative to the fixed columns 16, so that the trolley 1 is not easy to move relative to the ground (usually, the wheels 15 are separated from the ground in the vaccination process).

Both the front and rear ends of the cart 1 in the first direction Y have footrests 17 inclined with respect to the horizontal direction. The pedal 17 is connected with the bottom plane in the trolley and extends towards the ground outside the trolley, so that the sheep can conveniently enter and exit the trolley 1 of the epidemic prevention device. In the vertical direction, the lowest position of the foot board 17 is not lower than the lowest position of the wheels 16, so that the trolley 1 can move conveniently.

The trolley 1 comprises a frame 11. The frame 11 is provided with a conveying line 2, a blocking mechanism 3, a neck pressing mechanism 4, an injection mechanism 5, a chip implanting mechanism 6, a chip scanning mechanism 7 and other mechanisms.

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 with the aisle fence 12.

The passageway fence 12 is connected to the conveying line 2 of the epidemic prevention device at one end, and can be connected with sheepfold at the other end, so that sheep can enter the conveying line 2 from the sheepfold in sequence to wait and carry out epidemic prevention. The width of the passageway fence 12 is only enough for one sheep to pass through, so that the phenomenon that a plurality of sheep are parallel to the inlet of the conveying line 2 to cause blockage is avoided. The aisle fence 12 comprises a plurality of detachably connected fence sections 121, which not only facilitates the disassembly, storage, transportation and assembly of the aisle fence 12, but also facilitates the adjustment of the length and direction of an aisle formed by the aisle fence 12.

The overall epidemic prevention process of the epidemic prevention device according to one embodiment of the invention comprises the following steps: first, the sheep are passed from the aisle barrier 12 to the conveyor line 2, which conveyor line 2 carries the sheep forward. Then, when the sheep moves to a certain position (when the sheep touches the blocking mechanism 3), the sensor 13 detects a signal, the conveying line 2 stops running, the chip scanning mechanism 7 extends out and scans whether a chip is on the sheep neck or not, if the chip is on the sheep neck, the chip information is stored in the computer, and meanwhile, the chip is not implanted; if there is no chip, then one chip needs to be implanted. Then, the chip scanning mechanism 7 is reset, and the neck pressing mechanism 4 presses down and clamps the sheep neck together with the blocking mechanism 3. After the sheep neck is fixed, the injection mechanism 5 executes the action of injecting the medicament, and meanwhile, the chip implanting mechanism 6 executes the action of implanting the chip according to the condition. And finally, resetting the injection mechanism 5, the chip planting mechanism 6 and the neck pressing mechanism 4, opening the blocking mechanism 3, starting the conveying line 2 to enable the sheep which has received the epidemic prevention to leave, and closing the blocking mechanism 3 after the front-section sensor 13 detects a signal that the sheep completely leaves to start the epidemic prevention of the next sheep.

Next, referring to fig. 3 to 6, the conveying line 2, the blocking mechanism 3, and the neck pressing mechanism 4 of the epidemic prevention apparatus according to an embodiment of the present invention will be described.

Transfer chain 2 includes anterior segment transfer chain 2a and back end transfer chain 2b, and the front end of anterior segment transfer chain 2a forms the export, and the back end of back end transfer chain 2b forms the entry, and two sections transfer chains can transport the sheep simultaneously. Sheep on rear end transfer chain 2b waits when the sheep on front end transfer chain 2a carries out the epidemic prevention, promptly, transfer chain 2b is equivalent to waiting for the district. The waiting area can eliminate unnecessary time waste among all links of epidemic prevention operation, save the time of the whole epidemic prevention process and enable the epidemic prevention process to be more efficient.

Every section transfer chain 2 all includes that two symmetry in opposite directions set up the conveyer belt 21 in the sheep body both sides, forms big-end-up's V-arrangement transport passage between two conveyer belts 21, is convenient for laminate sheep body in order to erect the sheep body and carry out the transportation. Two conveyer belts of back end transfer chain 2b turn over to the one side of keeping away from the sheep body at the entrance to form the entry of tubaeform transfer chain 2, be convenient for guide sheep to get into the transfer passage.

Preferably, with reference to fig. 6, the minimum distance L between the two conveyor belts 21 is not greater than 250mm, and the acute angle M included between the two conveyor belts 21 is 15 ° to 25 ° so as to better fit the lamb body, enabling a better definition of the lamb body. More preferably, the minimum distance L between the two conveyor belts 21 is 200mm to 250mm, more adapted to the actual shape of the lamb body.

In the present embodiment, the angle and the minimum distance between the two conveyor belts 21 can be adjusted according to actual conditions. Specifically, referring to fig. 6, in the present embodiment, two conveyor belts 21 are connected to the frame 11 by a first connection portion 111 and a second connection portion 112. The first connecting portion 111 is capable of reciprocating in the second direction X with respect to the frame 11, and the first connecting portion 111 rotatably connects the conveyor belt 21 with the frame 11. The second connecting portion 112 is capable of reciprocating in the vertical direction with respect to the frame 11, and the second connecting portion 112 rotatably connects the conveyor belts 21 to the frame 11, so that the minimum distance L and the included acute angle M between the two conveyor belts 21 can be adjusted.

It should be understood that the minimum distance L and the included acute angle M between the two opposite conveyor belts 21 of the epidemic prevention apparatus according to the present invention can be adjusted, and are not limited to the above manner. For example, in the case where the angle between the conveyor belt 21 and the frame 11 can be controlled, only the first connecting portion 111 may be provided without providing the second connecting portion 112; alternatively, in the case where the angle between the conveyor belt 21 and the frame 11 can be controlled, only the second connecting portion 112 may be provided without providing the first connecting portion 111. For example, the first connecting portion 111 may be configured to reciprocate in the second direction X with respect to the frame 11, or may be configured to be fixed with respect to the frame 11, the former being capable of adjusting the minimum distance L and the included acute angle M, and the latter being capable of adjusting only the included acute angle M. For another example, one of the two conveyor belts 21 may be fixed and the other may be adjustable.

It will be appreciated that when the sheep are gripped by the two conveyor belts 21, the legs of the sheep leave the ground, and in this state, the sheep are difficult to struggle greatly, which provides a good basis for the subsequent epidemic prevention work. Therefore, the conveying line 2 not only plays a role of conveying the sheep along the first direction Y, but also plays a role of fixing the sheep at the position of epidemic prevention operation.

Two other mechanisms for securing the sheep, namely the blocking mechanism 3 and the neck-pressing mechanism 4, will be described.

Referring to fig. 5, a blocking mechanism 3 is provided at the exit of the transportation path formed by the transportation line 2, and a blocking portion 31 of the blocking mechanism 3 can be opened or closed for controlling the sheep on the transportation line 2 to remain at the exit or to be separated from the transportation path from the front. Specifically, in the present embodiment, the blocking portion 31 is hinged to the frame 11 on the outlet side of the transportation channel, the blocking portion 31 is further connected to the blocking cylinder 32 at a non-hinged position, one end of the blocking cylinder 32 is fixed to the frame 11 (not shown in the figure), and the other end of the blocking cylinder can stretch and retract to drive the blocking portion 31 to rotate around the hinged side so as to block the outlet of the transportation line 2. The stopper 31 of the stopper mechanism 3 in the closed state is in contact with the front neck of the sheep to serve as a lower reference for the neck pressing mechanism 4 to clamp the neck. The upper side of the blocking portion 31 protrudes forward of the transportation passage with respect to the lower side to be adapted to the shape of the neck of the sheep. The blocking part 31 is wrapped with flexible materials outside the contact part of the sheep, so that the sheep is prevented from being injured.

The neck pressing mechanism 4 is disposed above an outlet of the transportation passage formed by the transportation line 2, and the neck pressing mechanism 4 includes a neck pressing portion 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 sheep nape, so that the neck of the sheep is fixed together with the blocking mechanism 3. Specifically, in the present embodiment, the neck pressing portion 41 of the neck pressing mechanism 4 is fixedly connected to the shaft 43 and can rotate along with the shaft 43, and the shaft 43 is disposed on the frame 11 (not shown) above the outlet of the conveying line 2. The shaft 43 is also provided at a middle portion thereof with a rotating arm 430 protruding in a radial direction of the shaft 43. The radial outer side of the rotating arm 430 is connected with a clamping cylinder 42, 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 activated, the shaft 43 can be driven to rotate, so that the shaft 43 drives the neck pressing part 41 to rotate, and the neck pressing part 41 is pressed against the sheep back neck. The neck pressing part 41 is made of flexible materials and is in contact with the sheep, so that the sheep is prevented from being injured.

In the embodiment, the position of the sheep in the epidemic prevention device is detected by the sensor. Specifically, a front-stage sensor 13 (see fig. 2) is provided in front of the front-stage conveying line 2 a. The front sensor 13 is an infrared sensor. Specifically, the detection position of the front sensor 13 is approximately at a portion where the stopper 31 in the closed state contacts the front neck of the sheep. When the front section sensor 13 detects that the sheep enters (namely, when the front neck of the sheep is contacted with the blocking part 31), the conveyor belt 21 of the front section conveyor line 2a stops running, so that the sheep receives epidemic prevention in situ; after the epidemic prevention is finished, the front section sensor 13 detects that the sheep completely leaves, and the blocking mechanism 3 is closed to wait for blocking the next sheep.

A rear-end sensor 14 (see fig. 1) is also provided between the rear-end line 2b and the front-end line 2 a. The rear stage sensor 14 is an infrared sensor. The rear sensor 14 has substantially the same height as the detection position of the front sensor 13. The rear section sensor 14 is used for detecting the position of the sheep on the rear section conveyor line 2 b. When the rear sensor 14 detects that the sheep completely enters 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 waits for the sheep on the front conveyor line 2a to receive epidemic prevention in situ.

The injection mechanism 5, the chip implanting mechanism 6 and the chip scanning mechanism 7 of the epidemic prevention apparatus according to one embodiment of the invention will be described below with reference to fig. 7 and 8. Wherein, the injection mechanism 5 is used for injecting vaccine for epidemic prevention into the sheep body at the side of the sheep neck. The chip implanting mechanism 6 is used for implanting the chip recorded with the sheep identity information into the sheep body at the sheep neck side. The chip scanning mechanism 7 is used for scanning at the chip pre-implantation position on the sheep neck side and identifying whether a chip is implanted or not, so as to determine whether the chip implanting mechanism 6 works or not.

Fig. 7 is a schematic view of the injection mechanism 5, the chip implanting mechanism 6, the chip scanning mechanism 7, the blocking mechanism 3 and the neck pressing mechanism 4 on a part of the frame 11 according to the present invention. The fixation of the neck of the sheep by the blocking means 3 and the neck-pressing means 4 determines the position where the vaccine injection and the chip implantation are subsequently performed on the sheep, i.e. the position lateral to the predetermined clamping position of the neck of the sheep is the position of the vaccine injection and the chip implantation. The injection mechanism 5, the chip implanting mechanism 6 and the chip scanning mechanism 7 are arranged on the side of the predetermined clamping position of the neck of the sheep. In the present embodiment, the injection mechanism 5, the chip implanting mechanism 6, and the chip scanning mechanism 7 are all provided on the frame 11 outside the outlet of the transportation passage. Wherein, the chip implanting 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.

Fig. 8 is a schematic diagram of the chip scanning mechanism 7 according to an embodiment of the present invention in an operating state. The chip scanning mechanism 7 is disposed above the side of the blocking mechanism 3 (see fig. 7), and when it is operated, the chip scanning mechanism 7 is driven by the air cylinder to move downward and toward the direction of the nape (to the position shown in fig. 8), thereby contacting with the nape and performing chip scanning.

The detailed structure of the injection mechanism 5 of the epidemic prevention apparatus according to an embodiment of the present invention will be described below with reference to fig. 9 and 10.

In the present embodiment, the injection mechanism 5 is provided on the frame 11 (not shown in the figure) on both sides outside the outlet of the transportation passage, and the injection mechanism 5 includes a needleless injector 51 and a medicine suction mechanism 52. It should be understood that reference herein to needleless injection is to the injection needle 511 not being required to be inserted subcutaneously into a bovine animal.

The medicine sucking mechanism 52 includes a medicine sucking needle 521 and a medicine bottle 522 containing a medicine. The drug-sucking needle 521 is driven into the drug vial 522 by the drug-sucking cylinder 523 above the drug-sucking needle, and the tail of the drug-sucking needle 521 is connected to the needleless injector 51 through a hose, so that the drug in the drug vial 522 can be supplied to the needleless injector 51. When it is desired to replace the vial 522, the suction cylinder 523 retracts to carry the suction needle 521 away from the vial 522.

The needleless injector 51 cooperates with the extend cylinder 53 and the trigger cylinder 54 to effect an automatic injection procedure in accordance with a predetermined program.

Specifically, in the present embodiment, the body of the needleless injector 51 is fixed to the connection plate 55, the injection buffer plate 56 is provided in front of the injection needle 511 of the needleless injector 51 in the injection direction, the injection buffer plate 56 is connected to the connection plate 55 by the spring 57, and the injection buffer plate 56 has a through hole through which the injection needle 511 passes to perform injection.

The stretching cylinder 53 is fixed on the frame 11 (not shown) on one side and connected with the connecting plate 55 on the other side, so that the stretching of the stretching cylinder 53 can drive the needleless injector 51 and the injection buffer plate 56 to be close to or far away from the neck of the sheep. When the injection buffer plate 56 approaches and contacts the nape of the sheep, the spring 57 is compressed, so that the injection needles 511 are pressed against the skin on the nape side through the through holes of the injection buffer plate 56. The injection buffer plate 56 contacts the neck of the animal prior to the injection needle 511 and exerts a pressure on the neck of the animal via the spring 57, facilitating the subsequent injection.

The body of the trigger pulling cylinder 54 is fixed relative to the body of the needle-free injector 51, the piston of the trigger pulling cylinder 54 extends to the front of the trigger of the needle-free injector 51, a protrusion 541 is arranged on the piston of the trigger pulling cylinder 54, and the protrusion 541 can pull the trigger of the needle-free injector 51 when the trigger pulling cylinder 54 retracts, so that the needle-free injector 51 can suck medicaments and inject the medicaments into the skin of sheep to complete the injection of vaccines.

The specific structure of the chip scanning mechanism 7 of the epidemic prevention apparatus according to an embodiment of the present invention will be described below with reference to fig. 11.

The chip scanning mechanism 7 comprises a chip scanning part 71, a first scanning air cylinder 72 and a second scanning air cylinder 73, wherein the first scanning air cylinder 72 can drive the chip scanning part 71 to reciprocate in the vertical direction, and the second scanning air cylinder 73 can drive the chip scanning part 71 to reciprocate in the second direction X, so that the chip scanning part 71 can be attached to a preset clamping position on the neck of a sheep to scan a chip and read chip information.

In this embodiment, in order to prevent the chip scanning mechanism 7 from interfering with the neck pressing mechanism 4 near the neck of the sheep, when the sheep on the conveying line 2 contacts the blocking mechanism 3 and does not advance any more (representing that the sheep is already in place), the chip scanning mechanism 7 starts to abut against the neck of the sheep before the neck pressing mechanism 4 performs chip scanning (at this time, the neck pressing mechanism 4 does not clamp the sheep). After chip scanning mechanism 7 accomplished the chip scanning, chip scanning mechanism 7 got back to the side top of barrier mechanism 3 by the cylinder drive, just started work after pressing neck mechanism 4, pressed neck mechanism 4 and barrier mechanism 3 to press from both sides tight sheep jointly, was prepared to carry out bacterin injection and chip implantation.

Next, a specific structure of the chip implanting mechanism 6 of the epidemic prevention apparatus according to an embodiment of the present invention will be described with reference to fig. 12 to 18.

Fig. 12 shows a specific structure of a chip module 60 used in the present embodiment. Chip assembly 60 includes a needle assembly 601 and a barrel assembly 605.

The needle assembly 601 includes a needle 602 and a sleeve 603 disposed over the needle 602. The needle 602 has a hollow needle tube 604, and the chip is housed inside the needle tube 604.

When the piston of the chip implanting cylinder 67 extends, the moving plate 652 is pushed, so that the needle 602 of the chip assembly 60 on the moving plate 652 penetrates through the through hole on the buffer plate 651 and enters the skin under the sheep neck (the spring 672 is hardly deformed during the movement of the moving plate 652); at this time, the moving plate 652 is limited by the limiting block 653 and does not move any more, the piston of the chip implanting cylinder 67 continues to extend, the spring 672 is compressed, the head 671 moves relative to the moving plate 652, and the head 671 pushes the ejector rod 607, so that the chip in the needle tube 604 is ejected out and enters subcutaneous tissues of the neck of the sheep; finally, the piston of the chip implanting cylinder 67 retracts, the return spring 608 and the spring 672 are both reset, and the piston of the chip implanting cylinder 67 pulls the moving plate 652 back to the original position through the protrusion on the other side of the ejector rod 671.

The working process of the chip planting mechanism 6 is as follows: the material receiving plate 62 moves out of the lowermost one of the needle assemblies 601 in the magazine 61, and then the needle gripping jaws 63 grip the needle 602 of the needle assembly 601, and the needle gripping sleeve jaws 64 grip the sleeve 603 of the needle assembly 601, separating the sleeve 603 from the needle 602. Needle gripping jaws 63 press needle 602 against the front of barrel assembly 605, and barrel assembly 605 is screwed together with needle 602 by tightening motor 66. Then, the buffer plate 651 of the connecting plate 65 is pressed against the neck of the sheep, and the chip implanting cylinder 67 is extended to implant the chips of the chip assembly 60 into the sheep.
