because each traction assembly (42) is designed at the half position of the top of the station plate (40), when the first two feet of a pig step on the station plate (40), the two traction assemblies (42) can not exert the effect completely, namely, the two pull-down assemblies (43) can not drive the two pressing assemblies (44) to completely press down, when the body of the pig completely enters the top of the station plate (40) and the head of the pig passes through the vertical plate (50), the traction assemblies (42) can exert the effect completely and drive the two pressing assemblies (44) to press down the back of the pig, after the four feet of the pig completely step on the top of the station plate (40) in the middle position, the height of the station plate (40) is reduced, when the station plate (40) descends, the first hinged seat (421) pulls one end of the telescopic rod (420), so that the telescopic rod (420) extends, and the second hinged seat (422) is subjected to the pulling force transmitted by the telescopic rod (420) exerted by the first hinged seat (421), the sliding column (110) is driven to slide downwards on the outer wall of the guide rod (11);

when the sliding column (110) slides downwards on the outer wall of the guide rod (11), the rectangular block body (430) is driven to descend because the rectangular block body (430) is fixedly connected with the sliding column (110), and because the steel cable (432) is sleeved with the rotating shaft (431), the rectangular block body (430) and the cross rod (41) are respectively inserted into two ends of the steel cable (432), and in addition, the first anti-dropping cap (433) is fixedly connected with one end, close to the rectangular block body (430), of the steel cable (432), the second anti-dropping cap (434) is fixedly connected with one end, close to the cross rod (41), of the steel cable (432), so that the rectangular block body (430) is abutted against the first anti-dropping cap (433), the end, close to the rectangular block body (430), of the steel cable (432) is driven to be tightened, the rotating shaft (431) is driven to rotate, one end, close to the cross rod (41), of the steel cable (432) is driven to be wound on the outer wall of the rotating shaft (431), and the second anti-dropping cap (434) is driven the cross rod, the buffer spring (435) has a buffer function, so that the sliding downwards is relatively slow, the back of the pig is prevented from being pressed and injured by the pressing assembly (44), and the strip-shaped gap provides an avoiding space for the cross rod (41);

when the cross rod (41) slides downwards, the cross plate (410) is fixedly connected with the cross rod (41), so that the cross plate (410) is driven to slide downwards, the elastic rod (441) is fixedly connected with the bottom of the cross plate (410), so that the elastic rod (441) is driven to slide downwards, one end of the elastic rod (441), which is far away from the cross plate (410), is fixedly connected with the top of the arc-shaped pressing plate (440), so that the back of a pig is pressed through the arc-shaped pressing plate (440), the protective sponge (443) is soft in material, when the arc-shaped pressing plate (440) presses the back of the pig, a protective effect is achieved, the pig is prevented from being injured, the conflict emotion of the pig can be reduced, the fixing effect is favorably improved, the two second limiting rods (442) and the two limiting blocks play a limiting role, the stability when the arc-shaped pressing plate (440) is pressed downwards is ensured, and the pressing effect of the arc-shaped pressing plate (440, because the standing plate (40), the cross rod (41), the traction assembly (42), the pull-down assembly (43) and the pressing assembly (44) are linked mechanisms, and the pigs only need four feet to step on the top of the standing plate (40), when the weight or the volume of the pigs is larger, the pressing force applied to the pigs by the arc-shaped pressing plate (440) is larger, the pressing force does not need to be adjusted through any external force, and only needs to be automatically applied according to the weight or the volume of the pigs, so that the practicability and the flexibility of the device are further improved;

s3: fixing the head of the pig:

after four feet of a pig completely step on the top right position of the standing plate (40), the pressure of the pig is reduced on the standing plate (40), the bottoms of the two insert rods (501) are fixedly connected with one end, close to the vertical plate (50), of the top of the standing plate (40), the tops of the two insert rods (501) are fixedly connected with the bottom of the cushion plate (500), so that the cushion plate (500) descends synchronously with the standing plate (40) to facilitate the pig head to pass through the arc-shaped opening, further, the pig head is clamped in the arc-shaped opening by the cushion plate (500) and is matched with the two arc-shaped pressing plates (440) to fix the pig, the limiting ring (502) and the limiting spring (503) play a role in buffering the descending of the cushion plate (500), so that the cushion plate (500) descends slowly according to the size of the pig head until the requirement of clamping the pig head is met, when the weight of the pig is larger, the lower the descending of the standing plate (40) is, the cushion plate (500) descending synchronously descends, therefore, the larger the arc-shaped opening is, namely the opening amplitude of the arc-shaped opening is in direct proportion to the dead weight of the pig, the head fixing requirements of the pigs of different sizes can be met, and the practicability of the device is further improved;

s4: fixing the tail of the pig:

the pig completely enters the top of the standing plate (40), and after the pig head passes through the arc-shaped opening, the position sensor (505) receives the approach of the pig head, namely the pig head completely enters the arc-shaped opening and is clamped by the backing plate (500), and sends the signal to the controller (3), so that the controller (3) starts the electric push rod (510), the output end of the electric push rod (510) extends downwards, the output end of the electric push rod (510) is fixedly connected with the baffle door (511), the baffle door (511) is slidably connected with the two baffle plates (52), the baffle door (511) is driven to slide between the two baffle plates (52) until the hip of the pig is blocked, namely the pig is enclosed and blocked between the standing plate (50), the baffle door (511) and the two baffle plates (52), the back cushion (512) facilitates the hip of the pig to lean against, and simultaneously plays a limiting effect, the circular groove is attached to the hip skin of the pig, and then increase the comfort level when the pig is fixed, reduce the struggle probability of pig, further reach and promote the fixed effect of pig, therefore make things convenient for going on of drenching work.
