Description

Technical Field

[0001] This invention relates to the field of cattle breeding and weighing technology, specifically to a precise yak channel weighing device. Background Technology

[0002] In the livestock farming sector, with the development of large-scale farming, accurate measurement of yak weight has become increasingly important. Accurate yak weight information not only helps in the scientific assessment of yak growth and the rational planning of feeding programs, but also provides precise measurement data for yak transactions. However, existing weighing equipment faces numerous challenges when dealing with yaks, a unique type of livestock. Yak farming environments are typically complex, and their hooves easily carry impurities such as mud, feces, and snow, making accurate weighing very difficult. Furthermore, yaks are inherently sensitive and prone to stress responses to environmental changes during weighing, affecting weighing efficiency and accuracy. In addition, traditional weighing methods lack the automation levels required for the high efficiency demands of large-scale farming.

[0003] Existing yak weighing equipment mostly employs a relatively simple platform scale structure. Typically, it uses a flat weighing platform and pressure sensors to measure the pressure exerted by the yak when standing, thus calculating the yak's weight. To guide the yak onto the weighing platform, a simple walkway or enclosure is usually installed. The pressure sensors on the weighing platform are mostly conventional strain gauge sensors. When the yak stands on the platform, the pressure causes the sensor to deform, changing its resistance value. By measuring the change in resistance, the pressure is calculated, and finally, the weight data is obtained. Controlling the yak's entry and exit from the weighing area relies primarily on manual guidance and manually opening and closing the gate.

[0004] Existing yak weighing equipment has shortcomings in terms of weighing accuracy. Because yak farming environments are mostly in complex areas such as high-altitude regions, yaks' hooves easily become covered in mud, feces, and, in winter, snow. When a yak steps onto the weighing platform, these impurities add extra weight to the weighing plate, i.e., tare weight. Traditional weighing equipment cannot effectively remove this extra weight caused by impurities, resulting in significant deviations in weighing data and failing to accurately reflect the yak's true weight. Over long-term use, the accumulation of impurities also corrodes and damages components such as pressure sensors, further affecting weighing accuracy and the equipment's lifespan, failing to meet the needs for precise measurement of yak weight and long-term stable use. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a precise yak channel weighing device, which solves the problem that traditional weighing devices cannot effectively remove the additional weight of impurities brought by yaks when they walk onto the weighing platform, resulting in large deviations in weighing data and failing to accurately reflect the true weight of yaks.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 9This invention provides a precise yak weighing device with a channel frame, including a channel frame 1. An installation platform 14 is fixedly connected to the inner side of the channel frame 1. The channel frame 1 serves as the main structure of the entire weighing device, with its bottom firmly installed on the ground, providing a foundation for the installation of other components. It also defines the channel range for yak weighing and guides the yaks into the weighing area. A weighing plate 22 is installed above the installation platform 14. Multiple sets of full-bridge strain gauge sensors with optimized stress structure are arranged inside the weighing plate 22 for accurately measuring the weight of the yaks. A controller 13 is installed on the outer side of the channel frame 1 to control and receive signals, control the operation of the components according to the signal instructions, coordinate the work of various parts of the device, and realize functions such as automatic door opening and closing and self-cleaning. A purging assembly is installed on the outside of the channel frame 1 to clean impurities on the weighing plate 22. An arc-shaped protective plate 7 is installed on the inside of the channel frame 1, and a buffer assembly is installed between the arc-shaped protective plate 7 and the channel frame 1 to protect the equipment. When a yak collides with the arc-shaped protective plate 7, the arc-shaped protective plate 7 is forced to slide inward toward the channel frame 1 and exerts a squeezing effect. Two gates 45 are installed on the inside of the channel frame 1 to isolate the yak and ensure that only one yak enters the weighing area at a time, thus achieving automated continuous weighing. A first fixed plate 2 is fixedly connected to the inside of the channel frame 1. A sliding assembly is installed on the top of the first fixed plate 2. The sliding assembly can precisely control the gates 45 to achieve smooth opening and closing of the gates 45.

[0023] Specifically, the main structure of the device is a channel frame 1, which is firmly installed on the ground at the bottom, defining the yak's passage and providing a mounting base for other components. An installation platform 14 is fixedly connected to the inside of the channel frame 1, and a weighing plate 22 is installed on the top of the installation platform 14. Multiple sets of full-bridge strain gauge sensors with optimized stress structure are arranged inside the weighing plate 22 for accurately measuring the weight of the yak.

[0024] In terms of control and maintenance, a controller 13 is installed on the outside of the channel frame 1 to receive signals and coordinate the operation of various components to achieve automated control; at the same time, a purging assembly is provided on the outside of the channel frame 1 to clean the mud, manure and snow brought in by the yak hooves on the weighing plate 22.

[0025] In terms of protection and execution, an arc-shaped protective plate 7 is installed on the inner side of the channel frame 1, and a buffer component is provided between it and the frame to buffer the impact force when the yak collides and protect the equipment. The inner side of the channel frame 1 is also provided with left and right symmetrical gates 45 to isolate a single yak to ensure continuous weighing.

A third fixing block 18 is fixedly connected to one end of the first spring 19. The second connecting rod 20 provides guidance for the sliding of the third fixing block 18 and the fourth fixing block 21, ensuring the stability and accuracy of the sliding of the push plate 17. The fourth fixing block 21 and the third fixing block 18 together compress the first spring 19, and when the first spring 19 resets, they assist the push plate 17 to return to the initial position. The third fixing block 18 is slidably connected to the outside of the second connecting rod 20 and the outside of the mounting platform 14. The push plate 17 is fixedly connected to the outside of the third fixing block 18. Multiple ventilation chambers are opened on the side of the push plate 17 away from the weighing plate 22. Multiple stops 63 are fixedly connected inside the push plate 17. Multiple fourth connecting rods 35 are rotatably connected inside the push plate 17. Vortex blades 36 are fixedly connected to the outside of the fourth connecting rods 35. A cleaning brush 37 is fixedly connected to the bottom of the fourth connecting rods 35. The baffle 63 blocks half of the high-speed airflow, allowing the airflow to enter through half of the ventilation cavity, changing the direction and intensity of the airflow to more effectively impact the vortex blades 36, driving the fourth connecting rod 35 and the cleaning brush 37 to rotate, thus improving the cleaning effect. During the self-cleaning process, the push plate 17 has a ventilation cavity inside, and the external high-speed airflow enters the ventilation cavity to impact the vortex blades 36. At the same time, the third fixing block 18 and the fourth fixing block 21 on both sides of the bottom of the push plate 17 compress the first spring 19 to provide a reset elastic force. The blowing assembly also includes a second fixing plate 9, which is fixedly connected to the outside of the channel frame 1. The first fixing block 10 is fixedly connected to the outside of the second fixing plate 9, and a cylinder 11 is fixedly connected to the outside of the first fixing block 10. A first wedge block 24 is fixedly connected to the output shaft of cylinder 11. A slide rail 15 is slidably connected to the outside of the first wedge block 24. A second fixing block 16 is fixedly connected to the outside of the slide rail 15. The second fixing block 16 is fixedly connected to the outside of the mounting platform 14. A second wedge block 25 is slidably connected to the outside of the first wedge block 24. Under the push of the output shaft of cylinder 11, it slides upward in the slide rail 15 and cooperates with the second wedge block 25 to convert the linear motion of cylinder 11 into the power of other components and start the cleaning structure action. A third connecting rod 27 is fixedly connected to the outside of the second wedge block 25. A third fixing plate 26 is fixedly connected to the bottom of the first fixing block 10. The third connecting rod 27 is slidably connected to the inside of the third fixing plate 26. A first connecting plate 28 is rotatably connected to the outside of the third connecting rod 27. The first connecting plate 28 is rotatably connected from bottom to top to the first transmission plate 29 and the second transmission plate 30. The other side of the first transmission plate 29 is rotatably connected to the third transmission plate 31. The second transmission plate 30 rotates under the drive of the first transmission plate 29, transmitting power to the third transmission plate 31 and the fourth transmission plate 32. The other side of the second transmission plate 30 is rotatably connected to the fourth transmission plate 32. The outer side of the third transmission plate 31 and the fourth transmission plate 32 is rotatably connected to the second connecting plate 33. The outer side of the second connecting plate 33 is rotatably connected to the third connecting plate 34. The outer side of the third connecting plate 34 is fixedly connected to the second support block 23. The second support block 23 is fixedly connected to the outer side of the push plate 17.

[0027] Specifically, the purging assembly achieves automatic cleaning through precise pneumatic and mechanical linkage. The assembly uses cylinder 11 as its core power source, and cylinder 11 is securely mounted on the outside of the channel frame 1 via a first fixing block 10 and a second fixing plate 9.

[0028] In terms of power transmission, the output shaft of cylinder 11 pushes the first wedge block 24 to slide upward within the slide rail 15, which is fixed to the outside of the mounting platform 14 by the second fixing block 16. The first wedge block 24 and the second wedge block 25 cooperate to convert the linear thrust into lateral power, driving the third connecting rod 27 to slide inside the third fixing plate 26. The third connecting rod 27 drives the first connecting plate 28, which in turn drives the first transmission plate 29 and the second transmission plate 30 to rotate, and then transmits power through the third transmission plate 31 and the fourth transmission plate 32. Finally, the second connecting plate 33 and the third connecting plate 34 drive the second support block 23 to smoothly push the push plate 17 to move.

[0029] In terms of cleaning execution, the push plate 17 has multiple ventilation chambers, and a baffle 63 is fixed inside each chamber. The baffle 63 is used to block half of the airflow, optimizing the airflow direction and intensity, so that it can efficiently impact the vortex blades 36 on the outside of the fourth connecting rod 35. This drives the fourth connecting rod 35 and the cleaning brush 37 at its bottom to rotate at high speed, effectively cleaning the concentrated area.

[0030] In terms of guidance and reset, the third fixing block 18 connected to the push plate 17 slides on the second connecting rod 20, and the second connecting rod 20 is fixed to the fourth fixing block 21 on the top of the mounting platform 14, providing precise guidance for the movement. At the same time, the third fixing block 18 and the fourth fixing block 21 together compress the first spring 19, using the potential energy stored in the spring to assist the push plate 17 in resetting after the operation is completed.

[0031] Please see the appendix Figure 12 - Appendix Figure 13In a preferred embodiment of the present invention, the buffer assembly includes a third connecting block 58, which is disposed inside the channel frame 1. A third sliding block 57 and a first sliding block 49 are slidably connected inside the third connecting block 58. A third spring 59 is fixedly connected to the opposite side of the third sliding block 57 and the first sliding block 49. The third sliding block 57 and the first sliding block 49 work together to compress the third spring 59 located in the middle of the third connecting block 58 to perform primary buffering and absorb the impact force of the yak collision. The third sliding block 57 and the first sliding block 49 are respectively fixedly connected to the second mounting plate 48 and the first mounting plate 47 on opposite sides. The second mounting plate 48 and the first mounting plate 47 are respectively fixedly connected to two sets of second connecting seats 50 and two sets of third connecting seats 56 on opposite sides. The second mounting plate 48 and the first mounting plate 47 are respectively fixedly connected to the inner side of the channel frame 1 and the arc-shaped protective plate 7. The arc-shaped protective plate 7 plays a protective role for the yaks during the entry and weighing process, and at the same time, it works with the buffer component to buffer the impact force generated by the collision of the yaks. The second connecting seat 50 is rotatably connected to the first connecting rod 51 in the middle. The second connecting seat 50 drives the first connecting rod 51 to transmit the impact force of the yak colliding with the arc-shaped protective plate 7 to the subsequent components, initiating a multi-stage buffering action. The other end of the first connecting rod 51 is rotatably connected to the third fixed rod 52. The outer side of the third fixed rod 52 is rotatably connected to the second connecting rod 55. The second connecting rod 55 is rotatably connected to the middle of the third connecting seat 56. The outer side of the third fixed rod 52 is fixedly connected to the second sliding block 54. The outer side of the second sliding block 54 is fixedly connected to the second spring 53. Under the drive of the first connecting rod 51 and the third fixed rod 52, the second sliding block 54 slides in the second connecting block 46 and squeezes the second spring 53, converting the impact force into the elastic potential energy of the spring, achieving secondary buffering. The other side of the second spring 53 is fixedly connected to the second connecting block 46. The second connecting block 46 is fixedly connected to the outer side of the third connecting block 58. The second sliding block 54 is slidably connected to the inner side of the second connecting block 46.

[0032] Specifically, the buffer assembly is located between the channel frame 1 and the arc-shaped protective plate 7, and is designed to absorb the impact force generated by the yak collision through a multi-level buffer mechanism to protect the equipment.

[0033] In terms of the primary buffer structure, the third connecting block 58 is located inside the channel frame 1, and a third sliding block 57 and a first sliding block 49 are slidably connected inside it. A third spring 59 is fixed between the two on opposite sides. The first sliding block 49 is connected to the first mounting plate 47 fixed inside the arc-shaped protective plate 7, and the third sliding block 57 is connected to the second mounting plate 48 fixed inside the channel frame 1. When the yak collides with the arc-shaped protective plate 7, the first sliding block 49 and the third sliding block 57 cooperate to compress the third spring 59 in the middle, absorbing the impact force through spring deformation, thus completing the primary buffer.

[0034] In terms of the two-stage linkage buffer, two sets of second connecting seats 50 and two sets of third connecting seats 56 are fixed on opposite sides of the second mounting plate 48 and the first mounting plate 47, respectively. The second connecting seat 50 is rotatably connected to the first connecting rod 51, and the third connecting seat 56 is rotatably connected to the second connecting rod 55. Both connecting rods are connected to the third fixed rod 52. When an impact occurs, the linkage mechanism transmits the force to the third fixed rod 52, causing the second sliding block 54 fixed on its outer side to slide within the second connecting block 46. The second connecting block 46 is fixed to the outer side of the third connecting block 58. The sliding of the second sliding block 54 compresses the second spring 53, converting the impact force into elastic potential energy, thus achieving secondary buffering.

A first connecting rod 4 is rotatably connected to the inside of the first support block 5. A second bevel gear 62 is fixedly connected to the inside of the first connecting rod 4. The second bevel gear 62 meshes with the first bevel gear 61. The first bevel gear 61 is driven to rotate by the output end of the motor 3, transmitting the power of the motor 3 to the second bevel gears 62 on both sides, thereby realizing the conversion and transmission of power and providing a power basis for the subsequent opening and closing action of the gate 45. A first rotating plate 38 is fixedly connected to the outer side of the first connecting rod 4. A second rotating plate 39 is rotatably connected to the other side of the first rotating plate 38. A sliding sleeve 40 is rotatably connected to the other side of the second rotating plate 39. A first fixed rod 6 is slidably connected to the inner side of the sliding sleeve 40. The second rotating plate 39 rotates under the drive of the first rotating plate 38, causing the sliding sleeve 40 to slide on the first fixed rod 6, further transmitting power and pushing the stop door 45 to open. The first fixed rod 6 is fixedly connected to the outer side of the first support block 5. A fourth fixed rod 60 is fixedly connected to the outer side of the sliding sleeve 40. Two third rotating plates 41 are sleeved on the outer periphery of the fourth fixed rod 60. The third rotating plate 41 is rotatably connected to the first connecting seat 42 at the end away from the fourth fixed rod 60. The first connecting seat 42 is fixedly connected to the outside of the stop door 45. The outside of the stop door 45 is fixedly connected to the second fixed rod 44. The third rotating plate 41 rotates in the first connecting seat 42 under the drive of the fourth fixed rod 60 at the bottom of the sliding sleeve 40, pushing the left and right symmetrical stop doors 45, so that the stop door 45 can rotate to open or close with the second fixed rod 44 in the first connecting block 43 as the center. Two first connecting blocks 43 are fixedly connected to the inside of the channel frame 1, and the second fixed rod 44 is rotatably connected to the inside of the first connecting block 43. A first diffuse reflection photoelectric sensor 8 and a second diffuse reflection photoelectric sensor 12 are fixedly connected from left to right on the inner side of the channel frame 1. The first diffuse reflection photoelectric sensor 8 is installed in the middle of the inner side of the channel frame 1 to sense the position of the yak. ​​When the yak passes by, it sends a signal to the controller 13. The controller 13 controls the sliding component to move in the opposite direction, which drives the barrier gate 45 to close, thus isolating a single yak. ​​The second diffuse reflection photoelectric sensor 12 is installed at the tail end of the inner side of the channel frame 1 to sense the signal that the yak has left after weighing and sends it to the controller 13. The controller 13 controls the motor 3 to operate and drive the barrier gate 45 to open, allowing the next yak to enter, thus realizing the automation of continuous weighing.

[0036] Specifically, in terms of power drive, the first support block 5 is fixed to the outside of the first fixed plate 2, and a motor 3 is fixed inside it. The first bevel gear 61 connected to the output end of the motor 3 meshes with the second bevel gear 62 at one end of the first connecting rod 4. When the motor 3 starts, it transmits power to the first connecting rod 4, which is rotatably connected in the first support block 5, through bevel gear transmission, providing the power foundation for the entire assembly.

[0037] In terms of transmission and execution, the first connecting rod 4 drives the outer first rotating plate 38 and the second rotating plate 39 to rotate, causing the sliding sleeve 40 to slide along the first fixed rod 6 fixed to the outer side of the first support block 5. The sliding sleeve 40 drives the two third rotating plates 41 to move through the fourth fixed rod 60 at the bottom, thereby pushing the first connecting seat 42 fixed on the stop door 45. This allows the stop door 45 to rotate and open precisely with the second fixed rod 44 fixed in the first connecting block 43 inside the channel frame 1 as the center.

[0038] In terms of automation control, a first diffuse reflection photoelectric sensor 8 is provided at the middle of the inner side of the channel frame 1 to sense the position of the yak and send a signal to the controller 13 to control the gate 45 to close to achieve single-head isolation; a second diffuse reflection photoelectric sensor 12 is provided at the inner tail end to send a signal when the yak leaves after weighing, and the controller 13 instructs the motor 3 to operate to open the gate 45 to allow the next yak to enter, thereby realizing the automation of continuous weighing operation.

[0039] Working principle: When weighing yaks is required, the bottom of the channel frame 1 is firmly installed on the ground. At the start of the weighing process, the controller 13 on one side of the channel frame 1 sends a command to start the motor 3 on the first fixed plate 2. The output end of the motor 3 rotates, driving the first bevel gear 61 to rotate. The first bevel gear 61 drives the second bevel gears 62 on both sides to rotate, causing the first rotating plate 38 on the outside of the first connecting rod 4 to drive the second rotating plate 39, which drives the sliding sleeve 40 to slide on the first fixed rod 6. The fourth fixed rod 60 fixed to the bottom of the sliding sleeve 40 then drives the third rotating plate 41, which is arranged vertically and vertically, to rotate within the first connecting seat 42, thereby pushing the left and right symmetrical gates 45, so that the gates 45 are connected to the first connecting block 43. The second fixed rod 44 inside is opened by rotating the center. At this time, the yak is driven into the channel and moves into the protection range of the arc-shaped protective plate 7 installed inside the channel frame 1. When the yak continues to move and is sensed by the first diffuse reflection photoelectric sensor 8 at the middle of the inner side of the channel frame 1, the above-mentioned sliding component moves in the opposite direction to drive the barrier door 45 to close, completing the single-head isolation. Then the yak walks onto the weighing plate 22 and uses multiple sets of full-bridge strain sensors with optimized force structure arranged inside the plate to achieve accurate weighing. After the weighing is completed, the yak leaves. When it is sensed by the second diffuse reflection photoelectric sensor 12 at the tail end of the inner side of the channel frame 1, the system controls the motor 3 to operate again to drive the barrier door 45 to open, allowing the next yak to enter, realizing fully automated continuous weighing. During the process of yaks entering and being weighed, in order to protect the equipment, the arc-shaped protective plate 7 works in conjunction with the buffer assembly installed near the inner side of the channel frame 1. When the yak walks and collides with the arc-shaped protective plate 7, the first mounting plate 47 on one side of the arc-shaped protective plate 7 drives the first sliding block 49 to slide into the third connecting block 58. At the same time, the second connecting seat 50 symmetrically arranged on the first mounting plate 47 drives the symmetrical first connecting rod 51, so that the first connecting rod 51 drives the second sliding block 54 to slide in the second connecting block 46 through the third fixed rod 52 and squeeze the second spring 53 for secondary buffering. The third fixed rod 52 simultaneously drives the second connecting rod 55 on the outside, and drives the second mounting plate 48 through the third connecting seat 56, so that the third sliding block 57 on one side of the second mounting plate 48, together with the first sliding block 49, squeezes the third spring 59 located in the middle of the third connecting block 58 for primary buffering. Through multi-stage linkage, the impact force is effectively absorbed. After multiple weighings, to address the issue of increased tare weight on the weighing plate 22 on the mounting platform 14 due to mud, manure, and snow carried by the yak's hooves, the equipment has a self-cleaning function. The output shaft of cylinder 11 pushes the fixed first wedge block 24 to slide upwards within the slide rail 15, engaging with the second wedge block 25. This, in turn, pushes the third connecting rod 27, fixed to one side of the second wedge block 25, to slide within the third fixed plate 26. The third connecting rod 27 drives the first connecting plate 28, which in turn causes the first transmission plate 29 and the second transmission plate 30 to rotate, respectively driving the third transmission plate 31 and the fourth transmission plate 32, ultimately driving the second connecting plate 33 and the third connecting plate 34 to continue... As the rotation continues, the second support block 23, fixed outside the third connecting plate 34, drives the push plate 17 below to slide. The third fixing blocks 18, symmetrically located on both sides of the bottom of the push plate 17, slide outside the second connecting rod 20 and cooperate with the fourth fixing block 21 to compress the first spring 19, providing a reset force. At this time, the external high-speed airflow is connected to the ventilation cavity set inside the push plate 17 through the ventilation pipe. Half of the high-speed airflow is blocked by the baffle 63 inside the ventilation cavity, allowing the airflow to enter through half of the ventilation cavity and impact the vortex blades 36 outside the fourth connecting rod 35. This drives the cleaning brush 37 at the bottom of the fourth connecting rod 35 to rotate at high speed, effectively cleaning the surface of the symmetrical weight plate 22 and ensuring weighing accuracy.
