Description

Technical Field

[0001] The present invention relates to the technical field of animal husbandry, and particularly to a measuring device for pigs. Background Art

[0002] In animal husbandry, accurate measurement of the body size and weight of pigs is crucial, which is of great significance for evaluating the growth and development, health status and meat yield of pigs.

[0003] Among them, in the prior art, the body size mainly depends on manual measurement. It is relatively easy to measure the body length and height, but it is very difficult to measure the waist circumference of pigs. Measuring with a flexible ruler is simple and direct, but the measurement efficiency is low. Moreover, in the actual measurement process, especially for pigs with a large body size, the staff often needs to walk around the pig to complete the measurement, or two people need to cooperate to achieve the measurement. This not only takes time but also requires a lot of physical strength, especially when the pig does not cooperate. On the other hand, due to the frequent movement of pigs, the flexible ruler is prone to slip or loosen during the measurement process, resulting in inaccurate measurement data. On the other hand, in the measurement process of the existing measurement method, the staff needs to keep a relatively close distance from the pig, which increases the risk of the staff's safety when measuring pigs that are not familiar with humans or are more aggressive. Summary of the Invention

[0004] To solve the above problems in the prior art, the present invention provides a measuring device for pigs, including: a limiting cage, a measurement channel is formed between the two ends of the limiting cage;

[0005] A flexible ruler, having a fixed end fixedly connected to one side of the limiting cage;

[0006] A suspension rope, connecting the middle section of the flexible ruler to the top of the limiting cage;

[0007] A warp hinge, arranged on the side opposite to the fixed end of the flexible ruler, and the tail end is connected to the movable end of the flexible ruler;

[0008] Wherein, the warp hinge includes a plurality of links, and both sides in the width direction of the link are respectively a hinge side and a driving side, and the driving side is close to the measurement channel;

[0009] Adjacent links form a hinge point C on the hinge side;

[0010] Both ends of the driving side form a force application point A and a force application point B;

[0011] The force application point A, the force application point B and the hinge point C form an angle a with the hinge point C as the vertex;

[0012] A first driving component, applying a pulling force N1 to the force application point A and the force application point B;

[0013] A limiting component is arranged between the warping hinge and the measuring channel and abuts against the driving side to keep the warping hinge in a vertical state.

[0014] A second driving component drives the warping hinge to perform a linear motion in the vertical direction and drives the warping hinge to extend out from the bottom of the limiting component.

[0015] Further, both ends of the driving side are provided with driving shafts, forming a stress point A and a stress point B.

[0016] The first driving component includes:

[0017] A driving rope is wound around one of the driving shafts of adjacent links to form an annular knot; and the end of the driving rope is fixedly connected to the driving shaft at the end of the warping hinge.

[0018] A first driving member is connected to the driving rope to apply a pulling force to the driving rope and contract the annular knot.

[0019] Further, both ends of the driving side are provided with driving shafts, forming a stress point A and a stress point B.

[0020] The first driving component includes a plurality of elastic driving members.

[0021] Wherein, both ends of the elastic driving member are respectively connected to one of the driving shafts of adjacent links.

[0022] When the link abuts against the limiting component, the elastic driving member is in an energy storage state, and when the link extends out of the limiting component, the elastic driving member releases elastic force.

[0023] Further, the limiting component has a guiding cavity penetrating through the limiting component in the vertical direction.

[0024] The warping hinge is arranged in the guiding cavity.

[0025] The warping hinge performs a linear motion so that the warping hinge continuously protrudes from the guiding cavity.

[0026] Further, an avoidance groove is arranged on the side wall of the limiting component facing the measuring channel.

[0027] Wherein, the width of the avoidance groove is at least greater than the width of the flexible ruler.

[0028] Wherein, the width of the avoidance groove is at least smaller than the thickness of the warping hinge.

[0029] Further, the second driving component includes:

[0030] The driving lead screw is arranged in the guiding cavity and is arranged along the length direction of the guiding cavity;

[0031] The second driving motor is arranged at the top or bottom of the limiting member and is connected to the driving lead screw;

[0032] The guiding slider is arranged in the guiding cavity and is hinged to the first end of the warp hinge, and the guiding slider has a threaded hole and forms a lead screw drive with the driving lead screw.

[0033] Furthermore, the second driving assembly includes:

[0034] The guiding slider is arranged in the guiding cavity and is hinged to the first end of the warp hinge;

[0035] The winch is fixedly arranged on the limiting cage or the limiting member and is located higher than the guiding slider;

[0036] The connecting rope has one end connected to the guiding slider and the other end connected to the winch;

[0037] When the winch rotates, the connecting rope is released or tightened.

[0038] Furthermore, it includes: a camera arranged towards the fixed end of the flexible ruler;

[0039] The control assembly is connected to the camera and is used for receiving the data information acquired by the camera.

[0040] Furthermore, a weighing device is arranged below the limiting cage, and the weighing device sends weight information to the control assembly.

[0041] Furthermore, one end of the limiting cage is an entrance and the other end is an exit;

[0042] Wherein, a scanning device is arranged above the entrance to identify the ear tag number of the pig to be measured and send it to the control assembly.

[0043] The beneficial effects of the present invention are reflected in that the first driving assembly applies a pulling force to adjacent links of the warp hinge, so that the warp hinge maintains a tendency to warp towards the measurement channel. The warp hinge is abutted and blocked by the limiting member from warping towards the measurement channel, and the second driving assembly is used to control the warp hinge to gradually determine the starting warping position of the warp hinge from the extension of the limiting member, realizing the gradual warping of the warp hinge. The warp hinge applies an oblique acting force to the flexible ruler, so that the flexible ruler surrounding the pig to be measured is tightly attached to the waist of the pig to be measured, and the difference between the two scales at the intersection of the flexible ruler can be used to obtain the waist circumference of the pig to be measured. When measuring the abdominal dimension of the pig to be measured, this measuring device does not require manual measurement, effectively improving the measuring efficiency and measuring accuracy, and will not cause any safety problems to the operator.

Detailed Description of the Invention

[0055] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0056] Embodiment 1:

[0057] Refer to Figure 1 - Figure 10 。

[0058] This embodiment provides a measuring device for pigs, including: a limiting cage 1, and a measuring channel 11 is formed between both ends of the limiting cage 1;

[0059] A flexible ruler 2, having a fixed end fixedly connected to one side of the limiting cage 1;

[0060] A suspension rope 3, connecting the middle section of the flexible ruler 2 to the top of the limiting cage 1;

[0061] A warping hinge 4, arranged on the opposite side of the fixed end of the flexible ruler 2, and the tail end is connected to the movable end of the flexible ruler 2;

[0062] Wherein, the warping hinge 4 includes a plurality of link sections 41, both sides in the width direction of the link section 41 are respectively a hinged side 42 and a driving side 43, and the driving side 43 is close to the measuring channel 11;

[0063] Adjacent link sections 41 form a hinge point C on the hinged side 42;

[0064] Both ends of the driving side 43 form a force application point A and a force application point B;

[0065] The force application point A, the force application point B and the hinge point C form an included angle a with the hinge point C as the vertex;

[0066] A first driving component 5, and a pulling force N1 is applied to the force application point A and the force application point B;

[0067] A limiting component 6, arranged between the warping hinge 4 and the measuring channel 11, abutting against the driving side 43 to keep the warping hinge 4 in a vertical state;

[0068] A second driving component 7, driving the warping hinge 4 to perform a linear motion in the vertical direction and driving the warping hinge 4 to extend from the bottom of the limiting component 6.

[0069] In the livestock industry, the body size data of pigs is of great significance for evaluating the growth status of pigs. However, it is very difficult to measure the waist circumference of pigs. When measuring, first drive the pig into the measuring cage, and then the worker needs to place one end of the flexible ruler 2 on one side of the pig, carry the other end of the flexible ruler 2 around to the other side, and finally pass this end of the flexible ruler 2 under the pig's belly back to the original side through a pole, so that the flexible ruler 2 forms a complete ring, and finally contract this ring to confirm the pig's waist circumference.

[0070] It should be noted that the workers have tried to pre-lay the flexible ruler 2 in the pig cage. After the pig comes in, directly wind the two ends of the flexible ruler 2 together to form a ring for measurement. However, when the pig comes in, it often kicks the flexible ruler 2 and arches the flexible ruler 2 to the position of the neck, resulting in inability to measure. Then the worker still needs to pull out the flexible ruler 2 and re-pass it through the pig's belly with a pole. Moreover, the work of laying the flexible ruler 2 flat is not simple. The worker still needs to repeatedly circle around the pig cage when laying and tightening the flexible ruler 2.

[0071] When passing the end of the flexible ruler 2 through the pig's belly with a pole, especially for larger pigs, the belly is very close to the bottom plate of the pig cage. The worker often needs to bend down and other actions to make the pole as parallel as possible to the bottom plate of the pig cage to pass the pole through. Then after the worker returns to the original side, the flexible ruler 2 still needs to be removed from the pole before the flexible ruler 2 can be contracted for measurement. Finally, the pole still needs to be pulled out for measuring the next pig.

[0072] Therefore, in the measurement process, the process of winding the flexible ruler 2 around the pig's waist is very troublesome.

[0073] For this reason, this application provides a measuring device for pigs, mainly aiming at measuring the waist circumference of pigs.

[0074] Specifically, it includes a limiting cage 1. The limiting cage 1 is just the pig cage for usually measuring pigs. The size of the limiting cage 1 is similar to the body size of the pig to be measured, and only allows the pig to be measured to enter from one end and exit from the other end, restricting the pig's activity space as much as possible, especially preventing the pig to be measured from turning around. A measuring channel 11 is formed between the exit and the entrance. The flexible ruler 2 is specifically tested in the measuring channel 11.

[0075] First, the flexible ruler 2 is fixed to one side of the limit cage 1. The end of the flexible ruler 2 fixed to the limit cage 1 is the fixed end. For most pig cages, there is a crossbeam across both sides of the pig cage at the top. The flexible ruler 2 is connected to this crossbeam through the suspension rope 3 to shape the flexible ruler 2. Specifically, the suspension rope 3 can be a simple elastic rope, so that the flexible ruler 2 it connects is higher than the back of the pig to be measured. At the same time, the flexible ruler 2 can release elastic force after being stressed, so that the flexible ruler 2 has sufficient freedom. At this time, after the pig to be measured enters the measurement channel 11, the fixed end of the flexible ruler 2 is on one side of the pig to be measured, and the flexible ruler 2 connected to the suspension rope 3 passes over the back of the pig. That is to say, after the flexible ruler 2 can pass through the other side of the pig to be measured and then pass through the belly of the pig to be measured, the main measurement work is completed.

[0076] For this, this embodiment further includes that a warping hinge 4 is arranged on the opposite side of the fixed end of the flexible ruler 2 to control the movable end of the flexible ruler 2 to pass under the belly of the pig to be measured and then cross with the flexible ruler 2.

[0077] The tail end of the warping hinge 4 is fixedly connected to the flexible ruler 2; it can be understood that at this time, the tail end of the warping hinge 4 can pass under the belly of the pig to be measured, and the flexible ruler 2 completes the action of surrounding the waist circumference of the pig to be measured.

[0078] For the hinge structure, its characteristic is that each link 41 can swing around the hinge axis, so the hinge structure can form any arc shape. The two sides in the width direction of the link 41 are respectively the hinge side 42 and the driving side 43, and the driving side 43 is close to the measurement channel 11;

[0079] Adjacent links 41 form a hinge point C at the hinge side 42;

[0080] Both ends of the driving side 43 form a force application point A and a force application point B;

[0081] The force application point A, the force application point B and the hinge point C form an angle a with the hinge point C as the vertex;

[0082] When the force application point A and the force application point B are subjected to tensile force, the distance between the two points continuously approaches, the degree of the angle a decreases, and the angles of adjacent two links 41 decrease synchronously with the degree of the angle a, and the overall warping hinge 4 bends.

[0083] This embodiment further includes a first driving component 5 that applies a tensile force N1 to the force application point A and the force application point B. There are many ways to apply tensile forces to the two points. For example, a tension spring is connected at the two points, so that the warping hinge 4 always maintains a bending trend. That is, when the warping hinge 4 is not subject to other external forces, the warping hinge 4 is bent. A limiting component 6 is arranged between the measurement channel 11 and the limiting component 6, which has a blocking effect on the warping hinge 4 and prevents the warping hinge 4 from bending towards the measurement channel 11. In this embodiment, the shape of the warping hinge 4 is restricted by the limiting component 6 (the abutment of the limiting component 3 on the warping hinge 4 is an other external force mentioned above) to keep it vertical. Specifically, the limiting component 6 is arranged in a cylindrical structure, and the warping hinge 4 is arranged inside the limiting component 6, and the warping hinge 4 abuts against the inside of the limiting component 6.

[0084] And this embodiment further includes a second driving component 7 that drives the warping hinge 4 to perform a linear motion in the vertical direction, drives the warping hinge 4 to extend from the bottom of the limiting component 6, and breaks away from the blocking of the limiting component 6, and the angle of the link 41 changes due to the tensile force N1. After being driven by the second driving component 7, the warping hinge 4 extends from the bottom of the limiting component 6 as the starting position of warping, so that the warping hinge 4 extends from below the side of the pig to be measured to above the opposite side.

[0085] More specifically, the distance between the limiting component 6 and the bottom surface of the limiting cage 1 is L1, and the length of a single link 41 of the warping hinge 4 is L2; L1 > L2; that is to say, at least when the warping hinge 4 is in a vertical state and the end of the warping hinge 4 touches the limiting cage 1, the end link 41 is completely out of the blocking of the limiting component 6. Therefore, after the end link 41 is lower than the limiting component 6, the end link 41 will bend towards the measurement channel 11 due to the action of the first driving component 5. Subsequently, the position of the warping hinge 4 continues to drop, and the adjacent link 41 at the end will also bend, and so on. Every time the warping hinge 4 drops a certain distance, the link 41 of the warping hinge 4 protruding from the limiting component 6 will bend. For this, this embodiment further includes a second driving component 7 to continuously lower the warping hinge 4 (after the measurement is completed, driving the warping hinge 4 to rise can be reset), that is, driving the warping hinge 4 to perform a linear motion in the vertical direction; and the length of the warping hinge 4 is less than the distance from the head end of the warping hinge 4 to the bottom surface of the limiting cage 1; this is to ensure that when the warping hinge 4 is at the initial height, the warping hinge 4 can maintain a vertical state.

[0086] It can be imagined that the arc formed by the bending of the warp hinge 4 continuously bends towards the measurement channel 11, and at the same time, it also bends upwards, continuously pushing the movable end of the flexible ruler 2 from one side diagonally downward to the opposite side diagonally upward. The fixed end of the flexible ruler 2 remains stationary, the middle position of the flexible ruler 2 is in a free state, the movable end of the flexible ruler 2 is continuously subjected to an oblique acting force, and the loop formed by the middle section of the flexible ruler 2 will continuously contract and closely adhere to the waist circumference of the pig to be measured. Subtracting the cross positions formed by the flexible ruler 2 can obtain the measured waist circumference.

[0087] During measurement, the worker can stand on the side of the fixed end of the flexible ruler 2, and set the control switch of the device on this side as well. After starting the device, the worker can record the cross position of the flexible ruler 2 by himself and calculate the waist circumference by himself.

[0088] For ease of understanding, it can be imagined that after the flexible ruler 2 passes through the belly of the pig to be measured,

[0089] When a person's hand grabs the movable end of the flexible ruler 2, the worker can also tighten the loop formed by the middle section of the flexible ruler 2 by applying an oblique force to the movable end of the flexible ruler 2 by pulling. Applying an oblique thrust to the flexible ruler 2 and applying an oblique pull to the flexible ruler 2 are essentially no different. The warp hinge 4 in this application is simulating the pulling force of a person's hand pulling the flexible ruler 2.

[0090] Embodiment 2

[0091] Refer to Figures 7 - 10 。

[0092] Specifically, how to apply a pulling force to the force application point A and the force application point B. Both ends of the driving side 43 have driving shafts 431, forming the force application point A and the force application point B;

[0093] The first driving assembly 5 includes:

[0094] A driving rope 51, which surrounds one driving shaft 431 of each adjacent link 41 respectively, forming a loop knot 511. Moreover, the end of the driving rope 51 is fixedly connected to the driving side 43 at the end of the warp hinge 4;

[0095] A first driving member 52, which is connected to the driving rope 51 and applies a pulling force to the driving rope 51.

[0096] Specifically, how to make the driving sides 43 approach each other. In this embodiment, a driving rope 51 is provided. The driving rope 51 surrounds one driving side 43 of each adjacent link 41 respectively, forming a loop knot 511; moreover, the end of the driving rope 51 is fixedly connected to the driving side 43 at the end of the warp hinge 4.

[0097] Pull the head end of the driving rope 51. The tail end of the driving rope 51 approaches the head end of the driving rope 51. During the force application process, each annular knot 511 of the driving rope 51 will receive a tightening force. The annular knot 511 of the driving rope 51 presses against the two adjacent driving sides 43, which is equivalent to the annular knot 511 applying a clamping force to the opening of the included angle a, that is, the pulling force N1, causing the angle of the included angle a to continuously contract, and further causing the warping hinge 4 to form an arc.

[0098] The first driving assembly 5 further includes a first driving member 52. When the warping link 41 is abutted by the limiting member 6, since the link 41 cannot swing, the annular knot 511 is relatively large. However, the first driving member 52 always applies a pulling force to the driving rope 51. Whenever a link 41 extends out of the limiting member 6, the first driving member 52 will pull a section of the driving rope 51. Specifically, the first driving member 52 can be set as a motor to wind the driving rope 51 through a rotating shaft; or set as a tension spring, with one end fixedly connected and the other end connected to the driving rope 51; or set as a counterweight, connected to the driving rope 51 and suspended in the air (when adopting the form of a tension spring or a counterweight, at least one reversing structure needs to be set above the head end of the warping hinge 4 so that the downward acting force can pull the driving rope 51 upward, and the reversing structure can be a fixed pulley or a fixed ring); it should be noted that when the warping hinge 4 is working, the warping hinge 4 will continuously descend. Therefore, when the first driving member 52 is in the form of a motor, the first driving member 52 should be connected to the second driving assembly 7 and descend synchronously with the warping hinge 4; and during the descending process of the warping hinge 4, the elongation of the driving rope 51 is usually less than the displacement of the warping hinge 4. Therefore, when adopting the form of a tension spring or a counterweight, the tension spring will continuously elongate and the counterweight will continuously move upward; adopting a tension spring and a counterweight has a lower cost and a simpler structure than adopting a motor. During the continuous warping process of the warping structure, the length in the horizontal direction continuously increases and the resistance arm grows. The first driving member 52 needs to provide a greater acting force to pull the driving rope 51. Therefore, the first driving member 52 in the form of a tension spring is more in line with the force received by the warping hinge 4 of the present application.

[0099] Embodiment 3

[0100] Refer to Figure 9 and Figure 10 。

[0101] This embodiment provides another structure for driving the warping hinge 4 to bend.

[0102] Both ends of the driving side 43 are provided with driving shafts 431, forming force application points A and B;

[0103] The first driving assembly 5 includes a plurality of elastic driving members 53;

[0104] Wherein, both ends of the elastic driving member 53 are respectively connected to one of the driving shafts 431 of the adjacent links 41;

[0105] When the link 41 abuts against the limiting member 6, the elastic driving member 53 is in an energy storage state. When the link 41 extends out of the limiting member 6, the elastic driving member 53 releases elastic force.

[0106] The first driving assembly 5 is provided with a plurality of elastic driving members 53, and the elastic driving member 53 can be specifically set as a spring piece or a tension spring. Both ends of the elastic driving member 53 are respectively connected to one of the driving shafts 431 of the adjacent links 41. When the warping hinge 4 is within the limiting member 6 and abuts against the limiting member 6, the elastic driving member 53 is in an energy storage state and is stretched. When a certain link 41 is driven by the first driving assembly 5 to break away from the limiting member 6, without the block of the limiting member 6, the elastic driving member 53 releases elastic force and the angle between this link 41 and the adjacent link 41 changes.

[0107] It should be noted in this embodiment that: First, the elastic driving members 53 in this embodiment are independent of each other, and the overall warping hinge 4 will not be prevented from bending due to the connection at the end of the warping hinge 4 being abutted. Therefore, the length of the limiting member 6 should be greater than the length L4 of the warping hinge 4, and blocking plates are provided on both sides in the width direction of the warping hinge 4. More preferably, the limiting member 6 is set as a cylindrical structure to directly wrap the warping hinge 4. Second, due to the continuous warping of the warping hinge 4, the subsequent elastic driving members 53 need to pry more links 41, so a greater elastic force is required. Therefore, elastic driving members 53 with different elastic force magnitudes should be selected, and the elastic force is greater closer to the first end of the warping hinge 4.

[0108] Embodiment 4

[0109] Refer to Figure 3 - Figure 5 。

[0110] The limiting member 6 has a guiding cavity 61 that penetrates the limiting member 6 in the vertical direction;

[0111] The warping hinge 4 is arranged in the guiding cavity 61;

[0112] The warping hinge 4 moves linearly along the guiding cavity 61 so that the warping hinge 4 continuously protrudes from the guiding cavity 61.

[0113] The limiting member 6 is set as a cylindrical structure, with both ends in the vertical direction penetrating, and a guiding cavity 61 is formed inside. The warping hinge 4 is arranged in the guiding cavity 61 so that the warping hinge 4 moves more stably during linear motion.

[0114] Furthermore, a side wall of the limiting component 6 facing the measuring channel 11 is provided with an avoidance groove 62; the width of the avoidance groove 62 is greater than the width of the tape measure 2, and the width of the avoidance groove 62 is less than the thickness of the warping hinge 4, so that the tape measure 2 can freely pass through the limiting component 6 while the wall surface of the guide cavity 61 can still limit the warping hinge 4.

[0120] A guide slider 73 is disposed in the guide cavity 61 and is hinged to the head end of the warping hinge 4. The guide slider 73 has a screw hole and forms a screw transmission with the driving screw 71.

[0122] This embodiment provides a specific structure of a second driving assembly 7 to enable the warping hinge 4 to perform linear motion along the vertical direction.

[0123] The second driving assembly 7 includes a driving screw 71, a second driving motor 72, and a guide slider 73.

The driving screw 71 is threadedly connected to the guide slider 73, and the second driving motor 72 drives the screw to rotate. The driving screw 71, the second driving motor 72, the guide slider 73, and the guide cavity 61 form a complete screw transmission mechanism. The guide slider 73 is hinged to the head end of the warping hinge 4, and the guide slider 73 drives the warping hinge 4 to perform linear motion as a whole.

[0130] The winch 74 is fixedly arranged on the limiting cage 1 or the limiting component 6 and is higher in position than the guiding slider 73;

[0131] The connecting rope 75 has one end connected to the guiding slider 73 and the other end connected to the winch 74;

[0132] When the winch 74 rotates, it releases the connecting rope 75 or winds up the connecting rope 75.

[0133] The guiding slider 73 is arranged in the guiding cavity 61 and is hinged to the head end of the warping hinge 4. The movement of the guiding slider 73 drives the warping hinge 4 to act. The winch 74 is fixedly arranged on the limiting cage 1 or the limiting component 6 and is higher in position than the guiding slider 73. The guiding slider 73 is connected to the winch 74 through the connecting rope 75. When the winch 74 rotates in one direction, the connecting rope 75 is wound up, pulling the guiding slider 73 to move upward. When the winch 74 rotates in the other direction, the connecting rope 75 is released, and the guiding slider 73 and the warping hinge 4 fall due to their own gravity. The warping hinge 4 needs to warp. Naturally, a lighter material should be selected. Therefore, in this embodiment, the guiding slider 73 should have a greater weight compared to the lead screw drive in Embodiment 5.

[0135] Refer to Figure 1 - Figure 3 。

[0136] The camera 81 is arranged facing the fixed end of the flexible ruler 2;

[0137] The control component 82 is connected to the camera 81 and is used for receiving the data information obtained by the camera 81.

[0138] For the tightened flexible ruler 2, the actual waist circumference length can be obtained only by subtracting the two at the crossing position of the flexible ruler 2. Calculating manually is too troublesome and there is a possibility of calculation errors. More automatedly, the data at the crossing position of the flexible ruler 2 is photographed by the camera 81 and sent to the control component 82 for calculation.

[0139] Furthermore, a weighing device 83 is arranged below the limiting cage 1, and the weighing device 83 sends the weight information to the control component 82. When recording data, it is often necessary to record the weight while measuring the waist circumference. In this embodiment, the weighing device 83 is arranged below the limiting cage 1 to measure and record the weight data of the pig to be measured at the same time, saving the work process.

[0140] Furthermore, one end of the limiting cage 1 is an entrance and the other end is an exit;

[0141] Above the inlet, a scanning device 84 is provided to identify the ear tag number of the pig to be measured and send it to the control component 82.

[0142] The scanning device 84 automatically identifies the ear tag number of the pig to be measured and associates the weight and waist circumference data with the corresponding pig to be measured.
