Description

Technical Field

[0001] This invention relates to the field of object size measurement, and in particular to a measuring device for measuring the shape of poultry eggs and its method of use. Background Technology

[0002] When measuring the size of an object, vernier calipers are usually used to obtain more accurate dimensional data. For regular objects, the measuring jaws of the vernier calipers can be stably clamped at the end of the egg, and the readings obtained are more accurate. However, for irregular objects, the measuring jaws of the vernier calipers cannot be stably clamped at the end of the egg, which increases the difficulty of dimensional measurement and produces a larger error in the measured degree.

[0003] Taking the measurement of poultry egg shape index as an example, one traditional method involves using calipers to clamp the long and short axes of the egg, recording the values ​​before calculating the egg shape index. However, the eggshell surface is smooth, and the caliper's measuring jaws cannot stably grip the eggshell, resulting in significant errors in the measurement readings. Furthermore, the eggshell is brittle, and the measuring jaws can easily damage it during the measurement process. Another method involves taking photos of poultry eggs with a camera and then using machine vision technology to extract the long and short axis dimensions from the photos and calculate the egg shape index. This method requires electrically powered measuring equipment and is expensive, making it unsuitable for widespread adoption due to limitations in the usage environment and cost.

[0004] Therefore, there is a need for a device that can accurately measure the major and minor axis dimensions of eggs while improving the ease of measurement and reducing the cost of the measuring device. Summary of the Invention

[0005] The purpose of this invention is to provide a method for measuring the long axis and short axis dimensions of poultry eggs using a poultry egg shape measuring device, thereby solving the problems existing in the prior art, achieving accurate measurement of the long axis and short axis dimensions of eggs, improving the convenience of measurement, and reducing the manufacturing cost of the measuring device.

[0007] A gear shaft is also provided on the base, with the gear shaft axis perpendicular to the base. A transmission gear is provided on the gear shaft, and a long shaft detection device is provided on the upright plate. The platform baffle and the long shaft detection device are located on opposite sides of the platform. When the support platform is lowered, the transmission rack drives the long shaft detection device to move horizontally through the transmission gear, and moves the long shaft detection device closer to the platform baffle.

[0008] A short axis detection device is also installed above the shelf. The short axis detection device is slidably connected to the upright plate, allowing the short axis detection device to slide in the vertical direction.

[0009] Furthermore, the shelf is also equipped with a slide rail that extends along the direction of movement of the long axis detection device. A slide table is provided on the slide rail, and a clamp for fixing the egg is provided on the side of the slide table.

[0010] Furthermore, the support frame is a multi-link mechanism, with two sets of multi-link mechanisms, symmetrically arranged at the bottom of the shelf with the straight line of the slide rail extension direction as the axis of symmetry.

[0011] Furthermore, the multi-link mechanism includes a first link, a second link, a third link, a fourth link, and a first horizontal connecting plate, a second horizontal connecting plate, a first vertical connecting plate, and a second vertical connecting plate that serve as connectors. The first horizontal connecting plate, the first link, the first vertical connecting plate, the second link, the second horizontal connecting plate, the third link, the second vertical connecting plate, the fourth link, and the first horizontal connecting plate are hinged end to end. One of the first horizontal connecting plates or the second horizontal connecting plate is connected to the bottom surface of the platform, and the other is connected to the base. Each hinge point in the multi-link mechanism is equipped with a torsion spring.

[0012] Furthermore, a limiting optical axis is also provided on the base, and the axis of the limiting optical axis is perpendicular to the base; a limiting plate is provided on the side of the first horizontal connecting plate and the second horizontal connecting plate, and a limiting through hole is provided on the limiting plate, and the limiting plate is slidably connected to the limiting optical axis through the limiting through hole.

[0013] Furthermore, when the support platform descends, the first vertical connecting plate or the second vertical connecting plate moves toward the vertical plate. The first vertical connecting plate or the second vertical connecting plate in the two sets of multi-link mechanisms are connected by a crossbar, and the transmission rack is set on the crossbar.

[0014] Furthermore, it also includes an indicator plate, which is set on the side of the upright plate away from the support platform. The indicator plate is provided with scale lines, and the long axis detection device and the short axis detection device are provided with an indicator structure that works in conjunction with the indicator plate.

[0015] Furthermore, the long axis detection device includes a long axis detection rod, a long axis baffle, and a long axis detection pointer. A vertical plate slide rail is provided on the vertical plate, and the long axis detection rod is slidably connected to the vertical plate through the vertical plate slide rail. The long axis detection rod has teeth on the side facing the gear shaft, and the teeth mesh with the gear on the gear shaft. A long axis baffle is provided at one end of the long axis detection rod facing the support platform, and a long axis detection pointer is provided at the other end. The long axis baffle is used to contact the other end of the long axis of the egg body, and the long axis detection pointer corresponds to the scale line.

[0016] Furthermore, the short axis detection device includes a short axis detection rod, a short axis limiting rod, and a short axis detection plate. The short axis limiting rod is perpendicular to the short axis detection rod. Multiple short axis limiting rings are arranged vertically on the upright plate, and the short axis limiting rings and the long axis detection device are arranged on opposite sides of the upright plate. The short axis limiting rod is slidably arranged inside the short axis limiting rings. The short axis detection plate is detachably connected to the end of the short axis detection rod facing the platform, and the short axis detection plate is located directly above the platform to contact the top of the short axis of the egg. The other end of the short axis detection rod is provided with a short axis detection pointer pointing to the indicator plate, and the short axis detection pointer corresponds to the scale line.

[0017] A method for using a poultry egg shape measuring device includes the following steps:

[0018] S1: Push the long axis baffle to abut against the platform baffle to determine the detection benchmark of the long axis detection device, and record the reading b1 of the long axis detection pointer on the horizontal axis of the indicator plate;

[0019] S2: Place the egg on the platform and make one end of the long axis of the egg contact the platform baffle. Then limit the egg. Under the action of the egg's weight, the platform will descend and drive the long axis baffle to move towards the platform baffle. After the whole device reaches a stationary state again, record the reading b2 of the long axis detection pointer on the horizontal axis of the indicator plate.

[0020] S3: Remove the short axis detection plate from the short axis detection device, insert the short axis limiting rod into the short axis limiting ring, and lower the short axis detection rod to the same height as the platform. Record the reading a1 of the short axis detection pointer on the longitudinal axis of the indicator plate at this moment.

[0021] S4: Raise the short axis limiting rod again and fix the short axis detection plate on the short axis detection rod. Let the short axis limiting rod fall in the short axis limiting ring again. After the short axis detection plate abuts against the upper side of the egg, record the reading a2 of the short axis detection pointer on the longitudinal axis of the indicator plate.

[0022] S5: The major axis dimension of the egg is determined to be the absolute value of b2-b1, and the minor axis dimension is determined to be the absolute value of a2-a1.

[0023] The present invention achieves the following technical effects compared to the prior art:

[0024] Before actual measurement, first, place one end of the long axis detection device against the platform baffle to determine the position of the other end of the long axis detection device, and use this position as the horizontal motion reference for the long axis detection device. Place the egg on the platform, with one end of the egg against the platform baffle. Under the weight of the egg, the platform moves downward. The support frame folds and drives the long axis detection device towards the platform through the transmission rack and gear shaft. The long axis detection device keeps the egg in contact with the platform baffle. The distance between the end of the long axis detection device away from the platform and the horizontal motion reference is the size of the egg's long axis. Then, measure the real-time height of the platform using the short axis detection device, and use this as the vertical motion reference for subsequent measurement of the egg's short axis. Finally, slide the short axis detection device vertically down along the upright plate and press it against the top of the egg. At this point, the distance between the short axis detection device and the vertical motion reference is the size of the egg's short axis.

[0025] After measuring the major and minor axis dimensions of poultry eggs using the aforementioned measuring device, the ratio between the major and minor axis dimensions is the poultry egg shape index. This device does not require an electricity supply, has a simple structure, can adapt to different usage environments, has low manufacturing costs, and can automatically measure the major and minor axis dimensions of poultry eggs, simplifying the measurement process, improving the accuracy of size measurement, and at the same time, it can also avoid eggshell damage and ensure the integrity of poultry eggs.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0034] The purpose of this invention is to provide a poultry egg shape measuring device and its usage method; while realizing the measurement of the long axis and short axis dimensions of poultry eggs, it simplifies the measurement process, improves the accuracy of size measurement, avoids eggshell damage, and ensures the integrity of poultry eggs;

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Please refer to Figure 1-3The measuring device includes a base 1, on which a support platform and a vertical plate 18 are mounted. The vertical plate 18 is located on one side of the support platform. The support platform includes a placement table 12 and a support frame located below the placement table 12. The placement table 12 is used to place the egg 24 to be tested. A platform baffle 8 is provided on the placement table 12. A transmission rack 16 is also provided on the support frame. A gear shaft 17 is also provided on the base 1. The axis of the gear shaft 17 is perpendicular to the base 1. A transmission gear is provided on the gear shaft 17, and the transmission gear meshes with the transmission rack 16. When the egg 24 is placed on the placement table 12, the weight of the egg 12 causes the placement table 12 to descend, and the transmission rack 16 and gear shaft 16 lower the egg 24. 7 drives the transmission gear to rotate; a long shaft detection device 3 is provided on the upright plate 18. The platform baffle 8 and the long shaft detection device 3 are located on opposite sides of the platform 12. When one end of the long shaft detection device 3 abuts against the platform baffle 8, the position of the other end of the long shaft detection device 3 is the horizontal motion reference of the long shaft detection device 3. When the platform 12 descends, the transmission rack 16 drives the long shaft detection device 3 to approach the platform 12 through the transmission gear. The long shaft detection device 3 pushes the egg body 24 placed on the platform 12 to always maintain abutment against the platform baffle 8. At this time, the distance between the end of the long shaft detection device 3 away from the platform baffle 8 and the horizontal motion reference is the long shaft dimension of the egg body 24.

[0037] A short axis detection device 2 is also provided above the platform 12. After the egg 24 is placed on the platform 12, the platform 12 is lowered and the short axis detection device slides down along the vertical plate 18 to determine the height of the platform 12 after it has been lowered. This height is used as the vertical movement reference for the short axis detection device 2. The short axis detection device 2 is then raised and pressed on the top of the egg 24. After the egg 24 is placed on the platform 12, the platform 12 is lowered under the weight of the egg 24 until the egg 24 is stuck between the long axis detection device 3 and the platform baffle 8, so that the long axis detection device 3 cannot continue to move towards the platform baffle 8. In this state, even if more weight is added to the platform 12, the platform 12 will not continue to move downward. After the short axis detection device 2 is pressed on the top of the egg 24, the change in the short axis detection device 2 relative to the vertical movement reference is the short axis dimension of the egg 24.

[0038] The aforementioned measuring device reduces measurement errors that occur during manual measurement of the major and minor axes of the egg body 24, improving measurement accuracy; it also frees up hands, reducing the difficulty of measuring the egg shape index, and avoids damage to the eggshell during handheld measurement. The major and minor axis dimensions of the egg body 24 are obtained through these measurements, and the egg shape index can be derived from the ratio of the major to minor axis dimensions.

[0039] After placing the egg 24 on the platform 12, it is necessary to manually maintain the contact between the egg 24 and the platform baffle 8. Furthermore, holding the egg 24 in hand cannot completely guarantee that the platform 12 will descend under the weight of the egg 24. Therefore, when the long-axis detection device 3 moves towards the platform baffle 8 under the action of the transmission rack 16, the movement of the long-axis detection device 3 pushes the egg 24, causing it to contact the platform baffle 8 on its own. This reduces the pressure between the eggshell and the platform 12. Friction is used to propel the slide rail 11 on the platform 12. The extension direction of the slide rail 11 is the same as the movement direction of the long axis detection device 3. A slide table 9 is provided on the slide rail 11. The egg 24 is placed on the slide table 9 and fixed by the claws 10 on the slide table 9 to prevent the egg 24 from slipping when pushed. Under the push of the long axis detection device 3, the clamping force of the claws 10 on the eggshell drives the slide table 9 to slide along the slide rail 11 towards the platform baffle 8 until the egg 24 comes into contact with the platform baffle 8.

[0040] The control structure at the bottom of the gripper 10 can be set to automatically clamp the egg 24 based on its own weight. That is, when the egg 24 is placed between the grippers 10, the grippers 10 automatically clamp the egg 24 under the weight of the egg 24. After the measurement is completed, when the egg 24 is removed from the grippers 10, the control structure at the bottom of the grippers 10 loses pressure and controls the grippers 10 to automatically release, making it easy to remove the egg 24 from the grippers 10. The grippers 10 are made of elastic material, and the grippers 10 automatically clamp the egg 24 under the action of their own plastic deformation. A flexible material is also sleeved on the outside of the elastic material to prevent the grippers 10 from damaging the eggshell.

[0041] The support frame set at the bottom of the shelf 12 can take many forms, as long as it can drive the transmission rack 16 to reciprocate in the horizontal direction during the rising and falling of the shelf 12.

[0042] Preferably, the support frame is a multi-link mechanism 14, and two sets are arranged side by side at the bottom of the platform 12. The two sets of multi-link mechanisms 14 are symmetrically arranged at the bottom of the platform 12 with the sliding direction of the slide rail 11 as the axis of symmetry.

[0043] Please refer to Figure 5To facilitate the connection between the multi-link mechanism 14 and the transmission rack 16 and the platform 12, and to ensure the stability of the connection between the multi-link mechanism 14 and the transmission rack 16 and the platform 12, the multi-link mechanism 14 includes a first link 14-1, a second link 14-2, a third link 14-3, a fourth link 14-4, and a first horizontal connecting plate 14-5, a second horizontal connecting plate 14-6, a first vertical connecting plate 14-7, and a second vertical connecting plate 14-8 that serve as connectors; and the first horizontal connecting plate 14-5, the first link 14-1, the first vertical connecting plate 14-8, the second horizontal connecting plate 14-6, the third vertical connecting plate 14-7, the fourth ...1, the third vertical connecting plate 14-2, the fourth horizontal connecting plate 14-3, the fifth horizontal connecting plate 14-4, the sixth horizontal connecting plate 14-5, the seventh horizontal connecting plate 14-6, the eighth vertical connecting plate 14-7, and the ninth vertical connecting plate 14-8 serve as connectors. The first horizontal connecting plate 14-7, the second connecting rod 14-2, the second horizontal connecting plate 14-6, the third connecting rod 14-3, the second vertical connecting plate 14-8, the fourth connecting rod 14-4, and the first horizontal connecting plate 14-5 are hinged end to end. One of the first horizontal connecting plate 14-5 or the second horizontal connecting plate 14-6 is connected to the bottom surface of the platform 12, and the other is connected to the base 1, so as to achieve the purpose of connecting the multi-link mechanism 14 with the platform 12 and the base 1 through a plane, thereby improving the stability of the connection between the link mechanism 14 and the base 1 and the platform 12.

[0044] To ensure that the platform 12 can maintain a certain height and return to its initial height after the egg 24 is removed, torsion springs are installed at the hinge points between the first connecting rod 14-1, the second connecting rod 14-2, the third connecting rod 14-3, the fourth connecting rod 14-4, the first horizontal connecting plate 14-5, the second horizontal connecting plate 14-6, the first vertical connecting plate 14-7, and the second vertical connecting plate 14-8. The torsion springs provide power for the platform 12 to return to its initial height. However, the elasticity of the torsion springs is insufficient to overcome the weight of the egg 24 and prevent the platform 12 from descending.

[0045] To improve the stability of the multi-link mechanism 14 during the lifting and lowering of the platform 12, a limiting optical axis 13 is provided on the base 1. The limiting optical axis 13 is set perpendicular to the base 1, and at least one limiting optical axis 13 is provided. A limiting plate 15 is provided on the side of the first horizontal connecting plate 14-5 and the second horizontal connecting plate 14-6. A limiting through hole is provided on the limiting plate 15, and the limiting through hole is sleeved on the limiting optical axis 13. The first horizontal connecting plate 14-5 and the second horizontal connecting plate 14-6 are slidably connected to the limiting optical axis 13 through the limiting through hole on the limiting plate 15. The limiting optical axis 13 ensures that the platform 12 moves in the vertical direction.

[0046] Based on the above scheme, a return spring is sleeved on the limiting optical axis 13, and the return spring is set between the two limiting plates 15 on the limiting optical axis 13. While the limiting optical axis 13 keeps the platform 12 moving up and down in the vertical direction, the return spring keeps the platform 12 at a certain height and provides the platform 12 with the reset power. The elastic force of the return spring is insufficient to overcome the gravity of the egg body 24 and prevent the platform 12 from falling.

[0047] With two sets of multi-link mechanisms 14, a crossbar can be set between the two first vertical connecting plates 14-7 or the two second vertical connecting plates 14-8 that are closest to the vertical plate 18. The transmission rack 16 is set in the middle of the crossbar to ensure that the two sets of multi-link mechanisms 14 drive the transmission rack 16 to reciprocate in the horizontal direction at the same time. This avoids uneven thrust when the two sets of multi-link mechanisms 14 drive the gear shaft 17 to start rotating, which would cause the platform 12 to wobble in the horizontal direction and improve the stability of the measuring device during the measurement process.

[0048] An indicator plate 23 is also provided on the side of the upright plate 18 away from the support platform. The indicator plate 23 is provided with scale lines 25. When the long axis detection device 3 and the short axis detection device 2 move in the horizontal and vertical directions, the scale lines 25 indicated by the indicating structure of the long axis detection device 3 and the short axis detection device 2 on the indicator plate 23 change accordingly, thereby determining the amount of change in the movement of the long axis detection device 3 and the short axis detection device 2. The long axis dimension and short axis dimension of the egg body 24 are obtained through the amount of change.

[0049] The long axis detection device 3 includes a long axis detection rod 20, a long axis baffle 21, and a long axis detection pointer 22. A vertical plate slide rail 19 is provided on the vertical plate 18. The long axis detection rod 20 is slidably connected to the vertical plate 18 via the vertical plate slide rail 19. The long axis detection rod 20 has teeth on the side facing the gear shaft 17, which mesh with the gear on the gear shaft 17. After the egg 24 is placed on the platform 12, the platform 12 descends, driving the gear on the gear shaft 17 to rotate via the transmission rack 16. The gear, through the teeth on the long axis detection rod 20, drives the long axis detection rod 20 to move along the vertical plate slide rail 19 towards the platform 12. The end of the long axis detection rod 20 facing the support platform is... The long axis baffle 21 and the long axis detection rod 20 push the egg body 24 placed on the slide table 9 toward the platform baffle 8 until the egg body 24 comes into contact with the platform baffle 8. At this time, the long axis detection rod 20 stops moving and the platform 12 stops descending. The other end of the long axis detection rod 20 is equipped with a long axis detection pointer 22. During the process of the long axis detection rod 20 pushing the egg body 24 toward the platform baffle 8, the scale line 25 indicated by the long axis detection pointer 22 on the indicator plate 23 changes accordingly. After the long axis detection device 3 stops, the absolute value of the difference between the values ​​represented by the scale line 25 indicated by the long axis detection pointer 22 before and after the measurement is the long axis dimension of the egg body 24.

[0050] Please refer to Figure 4The short axis detection device 2 includes a short axis detection rod 6, a short axis limiting rod 5, and a short axis detection plate 4. The short axis limiting rod 5 is vertically connected to the short axis detection rod 6. Multiple short axis limiting rings 26 are arranged vertically on the upright plate 18, and the short axis limiting rings 26 and the long axis detection device 3 are arranged on opposite sides of the upright plate 18. The short axis limiting rod 5 is slidably arranged in the short axis limiting rings 26. The short axis detection plate 4 is detachably connected to the end of the short axis detection rod 6 facing the platform 12, and the short axis detection plate 4 is located directly above the platform 12. When measuring the size of the egg 24, the short axis detection plate 4 and the short axis detection rod 6 need to be separated to prevent the egg 24 or the gripper 10 from obstructing the downward movement of the short axis detection rod 6.

[0051] After the egg body 24 is placed on the platform 12, the platform 12 descends. When the platform 12 reaches a stationary state, the short axis detection rod 6 is controlled to slide down along the limiting direction of the short axis limiting ring 26 until the short axis limiting rod 5 is flush with the upper surface of the slide table 9, so as to determine the reference when the short axis detection rod 6 moves in the vertical direction. The end of the short axis detection rod 6 away from the platform 12 bends towards the base 1, and a short axis detection pointer 7 is set at the bent end. The change of the scale line 25 indicated by the short axis detection pointer 7 on the indicator plate 23 is used to reflect the change in the short axis detection device 2 in the vertical direction, thereby determining the short axis dimension of the egg body 24.

[0052] This application also discloses a method for using a poultry egg shape measuring device, including the following steps:

[0053] S1: Push the long axis baffle 21 to abut against the platform baffle 8 to determine the detection benchmark of the long axis detection device 3, and record the reading b1 of the long axis detection pointer 22 on the horizontal axis of the indicator plate 23;

[0054] S2: Place the egg body 24 on the platform 12 and make one end of the long axis of the egg body 24 contact the platform baffle 8. Then limit the egg body 24. Under the action of the weight of the egg body 24, the platform 12 descends and drives the long axis baffle 21 to move towards the platform baffle 8. After the whole device reaches a stationary state again, record the reading b2 of the long axis detection pointer 22 on the horizontal axis of the indicator plate 23.

[0055] In this step, after the egg 24 is placed on the platform 12, it is necessary to manually control the egg 24 to maintain contact with the platform baffle 8. Therefore, a slide rail 11 is provided on the platform 12. The slide rail 11 extends along the movement direction of the long axis detection device 3. A slide table 9 is provided on the slide rail 11. The slide table 9 can slide along the slide rail 11. After the egg 24 is placed on the slide table 9, it is not necessary to control the egg 24 to contact with the platform baffle 8. Under the action of the weight of the egg 24, the platform 12 descends, and the long axis baffle 21 pushes the egg 24 to slide on the slide rail until the egg 24 contacts the platform baffle 8. At the same time, in order to prevent the egg 24 from slipping off the slide table 9, a clamp 10 for fixing the egg 24 is provided on the side of the slide table 9.

[0056] S3: Remove the short axis detection plate 4 from the short axis detection device 2, insert the short axis limiting rod 5 into the short axis limiting ring 26, and lower the short axis detection rod 6 to the same height as the platform 12. Record the reading a1 of the short axis detection pointer 7 on the longitudinal axis of the indicator plate 23 at this moment.

[0057] S4: Raise the short axis limiting rod 5 again and fix the short axis detection plate 4 on the short axis detection rod 6. Let the short axis limiting rod 5 fall in the short axis limiting ring 26 again. After the short axis detection plate 4 abuts against the upper side of the egg body 24, record the reading a2 of the short axis detection pointer 7 on the longitudinal axis of the indicator plate 23.

[0058] S5: The major axis dimension of egg body 24 is the absolute value of b2-b1, and the minor axis dimension is the absolute value of a2-a1.
