Detailed implementation manners

[0041] 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 the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] The object of the present invention is to provide a weighing and measuring device to solve the problems existing in the prior art. Installation openings are provided on the side fences on both the left and right sides, and U-shaped grooves are provided on the installation openings. Placement rods are provided on the temporary retaining guardrail and the ear tag identification plate. Through the cooperation of the placement rods and the U-shaped grooves, the temporary retaining guardrail and the ear tag identification plate can be disassembled and assembled on the installation openings of the side fences at any time. Then, according to whether the electronic ear tag of the livestock is on the left side or the right side, the temporary retaining guardrail and the ear tag identification plate are swapped with each other, so that the ear tag identification plate corresponds to the ear side where the livestock electronic ear tag is located, thereby being able to adapt to livestock with different ear sides (such as cattle, sheep, etc.).

[0043] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] This embodiment provides a weighing and measuring device, as Figures 1 to 17 shown, including a main frame 1, an ear tag identification plate 5, and a temporary retaining guardrail 6. A weighing platform is installed at the bottom of the main frame 1 for weighing livestock, such as cattle, sheep, etc. An inlet is provided at the front end of the main frame 1, and an outlet is provided at the rear end of the main frame 1. Opening and closing doors are provided on both the inlet and the outlet. Side fences 2 are provided on both the left and right sides of the main frame 1. Installation openings 18 are provided at one end of the left and right side fences 2 close to the outlet. The installation openings 18 can accommodate the ear tag identification plate 5 or the temporary retaining guardrail 6. U-shaped grooves 19 are symmetrically provided on both side walls of the installation openings 18, and the openings of the U-shaped grooves 19 face upward. Placement rods 20 are provided on both the ear tag identification plate 5 and the temporary retaining guardrail 6. The placement rods 20 are matched with the positions of the U-shaped grooves 19 for being placed into the U-shaped grooves 19. Through the placement rods 20 and the U-shaped grooves 19, the ear tag identification plate 5 or the temporary retaining guardrail 6 can be respectively installed on the installation openings 18 of the left and right side fences 2. When the electronic ear tag is on the left ear of the livestock, the ear tag identification plate 5 is placed on the installation opening 18 of the left side fence 2, and the corresponding temporary retaining guardrail 6 is placed on the installation opening 18 of the right side fence 2. When the electronic ear tag is on the right ear of the livestock, the ear tag identification plate 5 is placed on the installation opening 18 of the right side fence 2, and the corresponding temporary retaining guardrail 6 is placed on the installation opening 18 of the left side fence 2, solving the problem that the existing weighing and measuring device cannot identify cattle with electronic ear tags on different sides. The ear tag identification plate 5 is integrated with a visual recognition device for identifying electronic ear tags, collecting body height, and collecting body condition.

[0045] In one embodiment, as Figures 1 to 17 shown, the visual recognition device includes an RFID electronic ear tag identifier and a camera. The electronic ear tag of the livestock is identified through the RFID electronic ear tag identifier, and the body height and body condition can be collected through the camera.

[0046] The cattle weighing and measuring device is a key equipment in modern livestock breeding management, mainly used to collect the weight of cattle, the identity information of electronic ear tags and body measurement data (such as the height of the withers), providing data support for scientific feeding, health monitoring and breeding optimization.

[0047] In one embodiment, as Figures 1 to 17 shown, the weighing platform includes a hollow weighing plate 12 and a weighing sensor. The hollow weighing plate 12 is installed on the measuring end of the weighing sensor, and the fixed end of the weighing sensor is installed at the bottom of the main frame 1. When livestock steps on the hollow weighing plate 12, the hollow weighing plate 12 will press down the measuring end of the weighing sensor, so that the weighing sensor will detect the magnitude of the pressure received and convert it into a weight value. There are many hollow holes on the hollow weighing plate 12 to facilitate the leakage of livestock urine and so on.

[0048] In one embodiment, as Figures 1 to 17 shown, the side fences 2 on the left and right sides of the main frame 1 can move relatively, such as approaching each other or moving away from each other, so as to adjust the space size between the left and right side fences 2 according to the fatness and thinness of livestock, reduce the activity space of livestock, and ensure the weighing accuracy of the weighing platform.

[0049] In one embodiment, as Figures 1 to 17 shown, hinge rods 21 are provided at the four corners of the outer side wall of the side fence 2. One end of the hinge rod 21 is hinged to the side fence 2, and the other end of the hinge rod 21 is hinged to the main frame 1, so that the side fence 2 can move inside or outside the main frame 1. The side fence 2 realizes the relative movement of mechanical control through a driving mechanism. The driving mechanism is installed at the top of one end of the main frame 1 provided with an inlet. The driving mechanism includes a driving rod 22, a slide rail 23, a slider 24 and a telescopic push rod 25. The slide rail 23 is fixedly installed on the top of the main frame 1, and the extending direction of the slide rail 23 is parallel to the front-back direction of the main frame 1. The fixed end of the telescopic push rod 25 is fixed on the top of the main frame 1, and the telescopic end of the telescopic push rod 25 is fixedly connected to the slider 24. The telescopic direction of the telescopic push rod 25 is parallel to the slide rail 23. The slider 24 is slidably connected to the slide rail 23. One end of the driving rod 22 is hinged to the slider 24, and the other end of the driving rod 22 is hinged to the inner side wall of the side fence 2. When the telescopic end of the telescopic push rod 25 extends or retracts, it will drive the slider 24 to move on the slide rail 23, thereby driving the driving rod 22 to move, so as to pull the left and right side fences 2 closer to each other or push the left and right side fences 2 away from each other. The telescopic push rod 25 can be an electric telescopic rod, a hydraulic telescopic rod or a pneumatic telescopic rod.

[0050] In one embodiment, as Figures 1 to 17As shown in the figure, the opening and closing door is a sliding door. The sliding doors at both the front and rear ends of the main frame 1 each include a door frame 3, a moving mechanism, two guide rails 26, and two door leaves 4. Entrance and exit channels for the door leaves 4 to enter and exit are provided on both the left and right sides of the door frame 3. The two guide rails 26 are fixedly connected side by side at the top of the door frame 3, and the extending direction of the guide rails 26 is parallel to the left-right direction of the door frame 3 (i.e., the left-right direction of the main frame 1). A pulley bracket 27 is provided at the top of the door leaf 4. The pulley bracket 27 is sleeved on the guide rail 26, and a pulley 28 is provided on the pulley bracket 27. The pulley 28 is arranged on the guide rail 26, enabling the door leaf 4 to move along the guide rail 26 through the pulley 28. The moving mechanism includes a driving motor 29, a gear 30, and two racks 31. The driving motor 29 is fixedly connected to the two guide rails 26. The gear 30 is fixedly connected to the motor shaft of the driving motor 29 coaxially. The gear 30 meshes between the two racks 31. The two racks 31 are respectively arranged at the tops of the two door leaves 4, and the extending direction of the racks 31 is parallel to the extending direction of the guide rail 26. When the motor shaft of the driving motor 29 rotates, it can drive the gear 30 to rotate, thereby driving the two racks 31 to move synchronously in opposite directions, and then driving the two door leaves 4 to move synchronously in opposite directions, that is, one door leaf 4 moves to the left and one door leaf 4 moves to the right, and the two door leaves 4 are opened synchronously. Compared with setting one door leaf 4 to move in one direction, the speed of opening and closing the door is relatively increased.

[0051] In an embodiment, as Figures 1 to 17 shown, a protective cover 8 is provided at the top of the door frame 3. The protective cover 8 covers the moving mechanism to prevent the moving mechanism from being exposed to the outside and rusting. Side baffles 9 are provided on both the left and right sides of the door frame 3. Entrance and exit openings 13 corresponding to the entrance and exit channels are provided on the side baffles 9 for the door leaves 4 to pass through.

[0052] In an embodiment, as Figures 1 to 17 shown, a position sensor is provided on the door frame 3. The position sensor is located at the preset opening position and closing position on the moving stroke of the door leaf 4. When the door leaf 4 moves to the preset opening position, the position sensor at the preset opening position will detect the door leaf 4, thereby determining that it is open. When the door leaf 4 moves to the preset closing position, the position sensor at the preset closing position will detect the door leaf 4, thereby determining that it is closed.

[0053] In an embodiment, as Figures 1 to 17As shown in the figure, an electric control box 17 is installed at the top of one end of the door frame 3 where there is an exit. A controller, which serves as the intelligent core, is provided inside the electric control box 17. One end of the main frame 1 where there is an entrance is provided with a control panel 11, and the control panel 11 is electrically connected to the controller inside the electric control box 17. The controller is electrically connected to a driving mechanism, a moving mechanism, a weighing sensor, a position sensor, an ear tag identification board 5, etc. The controller receives and conveys the instructions of the control panel 11, and at the same time also transmits the collected information to the control panel 11. The control panel 11 is provided with a screen, a numeric keypad, and buttons. Through the screen, weighing information, ear tag information, etc. can be displayed. Through the numeric keypad, buttons, etc., different door opening methods can be set for the moving mechanism. The door opening methods are roughly divided into timed door opening and closing, door opening and closing during the collection process, and active control door opening and closing. For timed door opening and closing, for example, after livestock enter, the door will automatically open after a certain period of time. For door opening and closing during the collection process, such as after livestock weighing and ear tag identification are completed, the door will automatically open. For active control door opening and closing, mainly, a button is pressed manually to open the door. The controller can be controlled through the control panel 11, and then the controller controls the driving mechanism to adjust the distance between the side fences 2 on both sides. The electric control box 17 is located at the top of the entire main frame 1, and only the control panel 11 is set on the side of the main frame 1. Compared with setting the electric control box 17 on the side of the main frame 1, it can reduce the obstruction of the line of sight. Through the screen of the control panel 11, the data collection process can have a centralized operation interface, and through the numeric keypad and buttons, operators can manually enter some information (such as ear numbers).

[0054] In one embodiment, as Figures 1 to 17 shown, a battery assembly, a reader, an action control box, and a weighing indicator are also provided inside the electric control box 17. The weighing indicator is electrically connected to the weighing sensor, and the reader is electrically connected to the ear tag identification board 5. The battery assembly, the reader, the action control box, and the weighing indicator are all electrically connected to the controller.

[0055] In one embodiment, as Figures 1 to 17 shown, the controller can be communicatively connected to a mobile phone app, a WeChat mini-program, a ranch network, etc. through a gateway, and then transmitted to a computer client through the ranch network.

[0056] In one embodiment, as Figures 1 to 17 shown, a shielding cover 7 is provided at the top of the main frame 1, and bottom baffles 10 are provided at the bottoms of the left and right sides of the main frame 1. The driving mechanism and the electric control box 17 are both located inside the shielding cover 7 to prevent the driving mechanism and the electric control box 17 from being exposed, rusted, or rained on, etc.

[0057] In one embodiment, as Figures 1 to 17As shown, the control panel 11 is installed on the main frame 1 through a rotating mechanism. The rotating mechanism includes a first bushing 14, a second bushing 15, and a rotating link 16. The first bushing 14 is fixedly connected to the main frame 1, and the axis of the first bushing 14 is arranged vertically. The rotating link 16 includes a first vertical rod section, a horizontal cross-bar section, and a second vertical rod section. One end of the first vertical rod section is rotatably connected to the inner wall of the first bushing 14, the other end of the first vertical rod section is fixedly connected to one end of the horizontal cross-bar section, the other end of the horizontal cross-bar section is fixedly connected to one end of the second vertical rod section, and the other end of the second vertical rod section is rotatably connected to the inner wall of the second bushing 15. The second bushing 15 is fixedly connected to the control panel 11. This rotating mechanism can enable the control panel 11 to rotate in the horizontal direction, thereby adjusting the control angle of the control panel 11. On the one hand, it is convenient for the operator to operate according to needs. On the other hand, the control panel 11 can be moved away from the side fence 2, reducing the obstruction of the side fence 2 and facilitating the observation of the internal situation.

[0058] In one embodiment, as Figures 1 to 17 shown, a side stop strip 32 is provided at the bottom of the inner wall of the side fence 2.

[0059] In the present invention, specific examples are used to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
