Detailed implementation manners

[0019] The technical solutions of the present invention will be further described in detail below through embodiments in conjunction with the accompanying drawings. However, the present invention is not limited to the following embodiments.

[0020] In livestock farming, it is usually necessary to weigh livestock regularly to monitor the growth and development of livestock. Weighing large livestock such as yaks is a core means of scientific farming, which can not only ensure animal health and production efficiency, but also provide a basis for genetic improvement and market decision-making.

[0021] In the prior art, livestock need to be driven to a weighbridge for weighing. For large-scale farms, this method is inefficient, and improper operation may cause stress to the livestock. After the livestock are stressed, they may not eat or eat less for several days, affecting the normal development of the livestock.

[0022] Supplementary feeding refers to the method of artificially adding feed to make up for the nutritional gap caused by insufficient natural forage intake or unbalanced nutrition of animals. The purpose of supplementary feeding is to improve the production performance of animals (such as weight gain, milk production, reproduction, etc.), improve the health status, or maintain their basic survival needs in a specific environment.

[0023] To solve the above problems, the purpose of the present invention is to provide an automatic weighing system for yaks, which is used for automatic weighing during the supplementary feeding of yaks; the automatic weighing system includes a weighing platform 10 arranged near the supplementary feeding area, a weighing support 11 for supporting the weighing platform 10, a lifting component arranged inside the weighing support 11 capable of lifting the weighing platform 10, a weighing unit 12 connected to the lifting component, and side baffles 13 arranged on both sides of the weighing platform 10. The weighing platform 10 is arranged on one side of the supplementary feeding area. Yaks need to stand on the weighing platform 10 for supplementary feeding. The side baffles 13 are used to limit that only one yak can be accommodated on the weighing platform 10, and when the yaks are being supplemented, all the weight is applied to the weighing platform 10; before the lifting component lifts the weighing platform 10, the weighing support 11 plays a supporting role for the weighing platform 10; the lifting component can lift the weighing platform 10 and separate it from the weighing support 11, and the weighing unit 12 can measure the weight of the weighing platform 10 and the yaks standing on the weighing platform 10.

[0024] In this embodiment, as Figure 1 , Figure 2 , Figure 3 shown, the supplementary feeding area can be a feeding trough, the feeding trough can be strip-shaped, and the supplementary feed is placed in the feeding trough. Livestock can stand on both sides of the feeding trough for supplementary feeding. The weighing support 11 includes a ground part and an underground part. The ground needs to be excavated before installing the weighing support 11. The underground part includes an underground frame body for installing the lifting component, and the ground part includes a ground frame body for placing the weighing platform 10. The side baffles 13 are arranged on the ground frame body. The weighing platform 10 is set at the height of the ground.

[0025] The ground frame includes a hole arranged in the center, and there are steps around the hole. The outer shape of the weighing platform 10 matches the hole and is placed on the steps. The steps limit the lowest position of the weighing platform 10. When the weighing platform 10 is at the lowest position, the yaks stand on the weighing platform 10, and the weight of the yaks is applied to the weighing support 11.

[0026] When weighing the yak, the lifting component lifts the weighing platform 10, and the weighing platform 10 is separated from the steps. After separation, the weight of the yak is applied to the lifting component.

[0027] The weighing unit 12 connected to the lifting component can measure the mass of the lifting movable part 22 of the lifting component, the weighing platform 10, and the yaks on the weighing platform 10.

[0028] In some embodiments, when the yak is not on the weighing platform 10, the automatic weighing system lifts the weighing platform 10 for weight calibration, that is, measuring the tare value. The weighed value when the yak stands on the weighing platform 10 minus the tare value gives the net weight value.

[0029] In some embodiments, when the weighing platforms 10 have similar specifications, the tare weight value of one weighing platform 10 can be applied to all the weighing platforms 10. For weighing platforms 10 with different specifications, the tare weight values can be calibrated for different specifications of weighing platforms 10 or for all the weighing platforms 10 respectively.

[0030] Further, the lifting assembly includes a lifting fixed part 21 and a lifting movable part 22. The lifting fixed part 21 is provided with a lifting driver 23 and a lifting transmission assembly connected to the lifting driver 23. The lifting movable part 22 is connected to the lifting transmission assembly, and the lifting movable part 22 is connected to the weighing platform 10; the lifting driver 23 can drive the lifting movable part 22 to move so as to lift the weighing platform 10 to a position where it is separated from the weighing support 11 or place the weighing platform 10 on the weighing support 11; The weighing unit 12 is arranged at the bottom of the lifting fixed part 21. After the weighing platform 10 is lifted and separated from the weighing support 11, the weighing unit 12 can measure the weight of the weighing platform 10 and the yak standing on the weighing platform 10.

[0031] In this embodiment, the lifting assembly includes a lifting fixed part 21 and a lifting movable part 22. The lifting fixed part 21 refers to the part whose height position remains unchanged during the lifting action or the descending and resetting action after lifting, while the lifting movable part 22 refers to the part whose height position changes during the lifting action or the descending and resetting action after lifting.

[0032] When the lifting movable part 22 is in the descending and resetting state, the top of the lifting movable part 22 is below the bottom of the weighing platform 10 and they do not contact. When the lifting movable part 22 is in the lifting state, the top of the lifting movable part 22 contacts the bottom of the weighing platform 10 and lifts the weighing platform 10 to separate the weighing platform 10 from the weighing support 11.

[0033] Further, the lifting driver 23 is a first motor. The lifting transmission assembly includes a first worm 24 connected to the output shaft of the lifting driver 23, a first gear set 25 connected to the first worm 24, a second worm 26 connected to the first gear set 25, a first transmission rod 27 connecting the first gear set 25 and the second worm 26, a third gear 28 connected to the second worm 26, and a first screw rod 29 coaxially connected to the third gear 28; an internal thread hole matching the first screw rod 29 is provided on the lifting movable part 22, and the rotation of the first screw rod 29 can drive the lifting movable part 22 to translate along the axis of the first screw rod 29; The lifting driver 23 can drive the first worm 24 to rotate, and successively drive the first screw rod 29 to rotate through the first gear set 25, the first transmission rod 27, the second worm 26, and the third gear 28.

[0034] In this embodiment, the lifting drive 23 is used to provide power for the lifting action and the lowering and resetting action of the lifting movable part 22.

[0035] In some embodiments, the automatic weighing system further includes a controller, which is connected to the lifting drive 23. The controller is used to control the action of the lifting drive 23, specifically including forward rotation, reverse rotation, and stop.

[0036] In some embodiments, the first worm 24, the first gear set 25, the second worm 26, the first transmission rod 27, the third gear 28, and the first screw 29 are respectively connected to the lifting fixed part 21 through support members. The support members are used to limit the positions of these components and provide installation and support functions.

[0037] In some embodiments, the meshing of the worm and the gear can be realized by the worm and the helical gear, and the normal base pitch of the worm and the meshing helical gear is equal.

[0038] The lifting drive 23 can drive the first worm 24 to rotate, and sequentially drive the first screw 29 to rotate through the first gear set 25, the first transmission rod 27, the second worm 26, and the third gear 28. The first screw 29 is in threaded fit with the lifting movable part 22, and the rotation of the first screw 29 can drive the lifting movable part 22 to translate, thereby realizing the lifting action and the lowering and resetting action.

[0039] Further, two sets of first gear sets 25 are arranged on both sides of the first worm 24. The first gear set 25 includes a first gear and a second gear that mesh with each other. The first gear meshes with the first worm 24. The second gears of the two sets of first gear sets 25 are respectively connected to two first transmission rods 27, and the second gear is arranged in the middle of the first transmission rod 27. Second worms 26 are respectively arranged at both ends of the first transmission rod 27; Four third gears 28 and a first screw 29 connected coaxially are arranged on the lifting fixed part 21. The second worms 26 at both ends of the two first transmission rods 27 respectively mesh with the four third gears 28; the thread helix directions of the two first screws 29 connected by the same first transmission rod 27 are the same; the thread helix directions of the two first screws 29 connected by the two first transmission rods 27 are opposite.

[0040] In this embodiment, a specific implementation manner of the lifting transmission assembly is proposed. Four first screws 29 are respectively arranged at the four corners of the lifting fixed part 21, and four threaded holes matching the first screws 29 are respectively arranged at the corresponding positions of the lifting movable part 22. The threaded hole can be an insert with an internal thread or a threaded hole directly machined on the bottom surface of the lifting movable part 22.

[0041] On both sides of the first worm 24, there are two first gear sets 25 respectively. The first gear set 25 can be of one size or multiple meshing sizes, and is used to transfer torque to the corresponding position of the first screw 29. The first worm 24 can drive the two first gear sets 25 to rotate.

[0042] In this embodiment, the first gear set 25 includes a first gear and a second gear that mesh with each other. The first gear meshes with the first worm 24, and the second gear meshes with the first transmission rod 27.

[0043] In this embodiment, the first transmission rod 27 is a long bar-shaped part. The middle of the first transmission rod 27 is connected to the second gear, and the two ends of the first transmission rod 27 are provided with second worms 26. The third gear 28 is coaxially connected with the first screw 29, and the rotation of the second worm 26 can drive the first screw 29 to rotate.

[0044] Since the helix directions of the first gears on both sides of the first worm 24 are opposite, the helix directions of the two first transmission rods 27 are opposite. In order to enable the first worm 24 to drive the lifting movable part 22 to rise or fall smoothly, the thread helix directions of the two first screws 29 connected by the same first transmission rod 27 are the same; the thread helix directions of the two first screws 29 connected by the two first transmission rods 27 are opposite.

[0045] Further, a plurality of support frames 31 are provided on the lifting movable part 22. The bottom of the support frame 31 is connected to the lifting movable part 22, and the top of the support frame 31 is used to contact the weighing platform 10; the plurality of support frames 31 can balance the contact force between the lifting movable part 22 and the weighing platform 10, so that the force between the lifting movable part 22 and the weighing platform 10 is uniform.

[0046] In this embodiment, the support frame 31 is of a frame structure. The support frame 31 includes a plurality of parallel cross beams, and these cross beams can contact the weighing platform 10 to balance the contact force between the lifting movable part 22 and the weighing platform 10, so that the force between the lifting movable part 22 and the weighing platform 10 is uniform.

[0048] In this embodiment, the automatic weighing system includes a plurality of weighing platforms 10 arranged side by side. The moving platform 32 can reciprocate back and forth between the weighing platforms 10. The moving platform 32 can be positioned at the bottom of a certain weighing platform 10. A lifting component is arranged on the moving platform 32.

[0049] Furthermore, the automatic weighing system further includes a translation track 34, and rollers matching the translation track 34 are arranged on the moving platform 32; A plurality of rollers are arranged on the moving platform 32, and the plurality of rollers include a driving roller 35 and a driven roller 36; the translation driver 33 is arranged on the moving platform 32, and a translation transmission component is further arranged on the moving platform 32; Two driving rollers 35 and two driven rollers 36 are arranged on the moving platform 32.

[0051] In the specific implementation process, the first transmission wheel 37 and the second transmission wheel 38 can be sprockets. Correspondingly, the transmission belt 39 is a chain. The two driving rollers 35 are respectively arranged at both ends of the transmission shaft.

The positioning component is used to assist in confirming whether the mobile platform 32 accurately moves to the bottom of a certain weighing platform 10, so as to avoid jamming when lifting the weighing platform 10 due to inaccurate positioning.

[0055] The position of the fixed positioning unit is relatively stationary with respect to the weighing platform 10, and each weighing platform 10 corresponds to a fixed positioning unit. The movable positioning unit is connected to the mobile platform 32.

The laser emitting unit 43 is used to emit laser, and the laser receiving unit 44 is used to detect the laser. When the laser emitting unit 43 and the laser receiving unit are aligned, the laser blocking unit blocks the laser, and the laser emitting unit cannot receive the laser, and the positioning of the mobile platform 32 is completed.

In the specific implementation process, when the mobile platform 32 moves, the movable end follows the movement and pulls the cable 47 to move, thereby pulling the connecting piece 48 to move synchronously, avoiding excessive resistance at the bent part of the drag chain body 45 due to excessive friction.

[0061] Furthermore, the mobile platform 32 further includes a support portion 51 and an elastic member 52. The elastic member 52 is used to connect the roller and the mobile platform 32; before the lifting assembly contacts the weighing platform 10, the elastic member 52 is in an extended state, and the support portion 51 is not in contact with the plane where the translation track 34 is located; after the lifting assembly contacts the weighing platform 10, the elastic member 52 is in a compressed state, and the support portion 51 is in contact with the plane where the translation track 34 is located.

[0062] In this embodiment, as Figure 6 , Figure 7 shown, the support portion 51 plays a supporting role. The elastic member 52 can be a compression spring. The elastic member 52 can lift the mobile platform 32 without external force. At this time, the bottom of the support portion 51 is suspended, and the translation drive 33 can drive the mobile platform 32 to move. After the lifting assembly contacts the weighing platform 10, the elastic member 52 is compressed, and the support portion 51 moves downward and contacts the plane where the translation track 34 is located. The support portion 51 plays a main weighing role, avoiding damage to the roller due to excessive pressure.

[0063] Furthermore, a main body identification unit 53 is provided on the plurality of weighing platforms 10. The automatic weighing system further includes a main body identification tag installed on the yak limb. The main body identification unit 53 can or is currently obtaining the information of the main body identification tag carried by the yak being supplemented on the corresponding weighing platform 10.

[0064] In this embodiment, as Figure 10 , Figure 11, the main body identification tag can be a radio frequency tag, the main body identification unit 53 can be a radio frequency reader 42, the yak wears the main body identification tag, and the information stored in the main body identification tag is associated with the yak's identity. When the yak stands on the weighing platform 10, the main body identification unit 53 can obtain the radio frequency tag information, and then associate the weighing information with the yak's identity.

[0065] In some embodiments, as Figure 12 shown, support beams are provided at the bottom of the weighing platform, and the support beams are in contact with the support frame for balancing the force.

[0066] This embodiment also provides an automatic weighing method for a yak herd, including: continuously detecting the main body identification tag within the identification range through the main body identification unit 53; after the main body identification unit 53 detects the main body identification tag, controlling the mobile platform 32 to move to the bottom of the weighing platform 10 where the main body identification unit 53 that detected the main body identification tag is located; controlling the lifting assembly to act, lifting the weighing platform 10 to a position where it is separated from the weighing support 11, obtaining the mass value measured by the weighing unit 12, which is related to the mass of the yak on the current weighing platform 10, subtracting the preset tare value to obtain the tare-free value, and associating and storing the tare-free value with the main body identification tag information; controlling the lifting assembly to act and placing the weighing platform 10 on the weighing support 11.

[0067] In this embodiment, the main body identification tag can be a radio frequency tag, the main body identification unit 53 can be a radio frequency reader 42, the yak wears the main body identification tag, and the information stored in the main body identification tag is associated with the yak's identity. When the yak stands on the weighing platform 10, the main body identification unit 53 can obtain the radio frequency tag information, and then associate the weighing information with the yak's identity. After the main body identification unit 53 detects the main body identification tag information, the controller controls the mobile platform 32 to move to the bottom of the weighing platform 10 for weighing operations. When weighing, the lifting assembly only needs to lift the weighing platform 10 to a position where it is separated from the weighing support 11 to perform weighing, specifically 3 - 5 millimeters, which is almost imperceptible to the yak and will not cause a stress response.
