Description

Technical Field

[0002] When measuring the size of an object, a vernier caliper is usually used to obtain more accurate size data. For regular objects, the measuring claws of the vernier caliper can be stably stuck on the end of the egg body, and the readings obtained can be more accurate. However, for irregular objects, the measuring claws of the vernier caliper cannot be stably stuck on the end of the egg body, which increases the difficulty of size measurement and the measured degree will also produce a large error.

[0003] Taking the measurement process of poultry egg shape index as an example, among the traditional measurement methods, one of the options is to use a vernier caliper to clamp the two ends of the long axis and the two ends of the short axis of the egg, record the values ​​of the long axis and the short axis, and then calculate the egg shape index; however, the surface of the eggshell is smooth, and the measuring claws of the vernier caliper cannot stably clamp on the surface of the eggshell, resulting in a large reading error of the measured size, and the eggshell is brittle, and the measuring claws can easily damage the eggshell during the measurement process; another option is to take a photo of the poultry egg with a camera, and then use machine vision technology to extract the long axis and short axis dimensions of the photo and calculate the egg shape index. This solution not only requires electric-driven measuring equipment, but also has a high cost. It is limited by the use environment and cost, and is not suitable for large-scale promotion.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The purpose of the present invention is to provide a poultry egg shape measuring device and a method for using the device; while achieving the measurement of the major axis size and minor axis size of the poultry egg body, the measuring process is simplified and the size measurement accuracy is improved; the eggshell is prevented from being damaged and the integrity of the poultry egg is ensured;

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Please refer to Figure 1-3The measuring device comprises a base 1, on which a supporting platform and a vertical plate 18 are arranged, the vertical plate 18 is arranged on one side of the supporting platform, the supporting platform comprises a placing table 12 and a supporting frame arranged below the placing table 12, the placing table 12 is used to place an egg body 24 to be tested, a platform baffle 8 is arranged on the placing table 12, and a transmission rack 16 is also arranged on the supporting frame; a gear shaft 17 is also arranged on the base 1, the axis of the gear shaft 17 is perpendicular to the base 1, a transmission gear is arranged on the gear shaft 17, and the transmission gear is meshed with the transmission rack 16, the egg body 24 is placed on the placing table 12, the placing table 12 is lowered by the gravity of the egg body 12, and the transmission rack 16 and the gear shaft 1 are used to move the egg body 24 to the placing table 12. 7 drives the transmission gear to rotate; a long axis detection device 3 is arranged on the vertical plate 18, and the platform baffle 8 and the long axis detection device 3 are located on the opposite side of the storage table 12. When one end of the long axis detection device 3 abuts against the platform baffle 8, the position of the other end of the long axis detection device 3 is the horizontal movement reference of the long axis detection device 3. When the storage table 12 descends, the transmission rack 16 drives the long axis detection device 3 to approach the storage table 12 through the transmission gear. The long axis detection device 3 pushes the egg body 24 placed on the storage table 12 to always maintain an abutment state with the platform baffle 8. At this time, the distance between the end of the long axis detection device 3 away from the platform baffle 8 and the horizontal movement reference is the long axis size of the egg body 24;

[0037] A short axis detection device 2 is also provided above the storage table 12. After the egg 24 is placed on the storage table 12, the storage table 12 is lowered, and the short axis detection is slid downward along the vertical plate 18 to determine the height of the storage table 12 after it is lowered, and this height is used as the movement reference of the short axis detection device 2 in the vertical direction, and then the short axis detection device 2 is lifted and pressed on the top of the egg 24. After the egg 24 is placed on the storage table 12, the storage table 12 drops under the gravity 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 toward the platform baffle 8. In this state, even if more weight is added to the storage table 12, the storage table 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 amount of the short axis detection device 2 relative to the movement reference in the vertical direction is the short axis size of the egg 24.

[0038] The measuring device can reduce the measurement error in the process of manually measuring the long and short axes of the egg body 24, improve the measurement accuracy, free the hands, reduce the difficulty of measuring the egg shape index, and avoid damage to the eggshell during the handheld measurement. The long axis size and the short axis size of the egg body 24 are obtained through the above measurement, and the egg shape index can be obtained by the ratio of the long axis size to the short axis size.

[0039] After placing the egg 24 on the storage table 12, it is not only necessary to manually keep the egg 24 in contact with the platform baffle 8, but also when holding the egg 24, it is not possible to completely ensure that the storage table 12 will drop under the gravity of the egg 24. Therefore, when the long axis detection device 3 moves toward the platform baffle 8 under the action of the transmission rack 16, the movement of the long axis detection device 3 is used to push the egg 24 so that the egg 24 can contact with the platform baffle 8 by itself, and in order to reduce the distance between the egg shell and the storage table 12, the egg 24 can be pushed to the platform baffle 8 by itself. Friction force, a slide rail 11 is arranged on the storage table 12, and 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 arranged on the slide rail 11, an egg body 24 is placed on the slide table 9, and the egg body 24 is fixed by the clamping claw 10 on the slide table 9 to prevent the egg body 24 from slipping when the egg body 24 is pushed, and under the push of the long axis detection device 3, the clamping force of the clamping claw 10 on the egg shell drives the slide table 9 to slide along the slide rail 11 toward the platform baffle 8 until the egg body 24 abuts against the platform baffle 8.

[0040] The control structure at the bottom of the clamp 10 can be set to a structure that automatically clamps the egg 24 by relying on the gravity of the egg 24, that is, when the egg 24 is placed between the clamps 10, the clamps 10 automatically clamp the egg 24 under the action of the gravity of the egg 24. After the measurement is completed, when the egg 24 is removed from the clamp 10, the control structure at the bottom of the clamp 10 loses pressure, and the control clamp 10 is automatically loosened, so that the egg 24 can be easily taken out of the clamp 10. The material of the clamp 10 is made of elastic material, and the automatic clamping of the egg 24 by the clamp 10 is achieved under the action of the plastic deformation of the clamp 10 itself. A flexible material is also sheathed on the outside of the elastic material to prevent the clamp 10 from causing damage to the eggshell.

[0041] The support frame arranged at the bottom of the storage platform 12 can be in various forms, as long as it can drive the transmission rack 16 to reciprocate in the horizontal direction during the ascending and descending process of the storage platform 12;

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

[0043] Please refer to Figure 5In order to facilitate the connection between the multi-link mechanism 14, the transmission rack 16 and the storage platform 12, and to ensure the stability of the connection between the multi-link mechanism 14, the transmission rack 16 and the storage 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; and the first horizontal connecting plate 14-5, the first link 14-1, the first vertical connecting plate 14-8 The straight 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 in sequence, 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 storage table 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 storage table 12 and the base 1 through a plane, thereby improving the stability of the connection between the connecting rod mechanism 14 and the base 1 and the storage table 12;

[0044] In order to ensure that the storage platform 12 can be maintained at a certain height and at the same time ensure that the storage platform 12 can be restored to its original height after the measurement is completed and the egg body 24 is removed, a torsion spring is arranged at the hinge points among 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 and the first vertical connecting plate 14-7, the second vertical connecting plate 14-8, and the torsion spring is used to provide power for the storage platform 12 to return to its initial height, wherein the elastic force of the torsion spring is not sufficient to overcome the gravity of the egg body 24 that prevents the storage platform 12 from descending.

[0045] In order to improve the stability of the multi-link mechanism 14 in the process of controlling the lifting of the storage platform 12, a limited optical axis 13 is arranged on the base 1, and the limited optical axis 13 is arranged vertically on the base 1. The number of the limited optical axis 13 is set at least one, and the side of the first horizontal connecting plate 14-5 and the second horizontal connecting plate 14-6 is provided with a limited plate 15, and the limited through hole is arranged on the limited through hole. The first horizontal connecting plate 14-5 and the second horizontal connecting plate 14-6 are slidably connected with the limited optical axis 13 through the limited through hole on the limited plate 15, and the storage platform 12 is ensured to move in the vertical direction through the limited optical axis 13;

[0046] On the basis of the above scheme, a reset spring is mounted on the limiting optical axis 13, and the reset spring is arranged between the two limiting plates 15 on the limiting optical axis 13. While the limiting optical axis 13 keeps the placing table 12 rising and falling in the vertical direction, the reset spring is used to keep the placing table 12 at a certain height and provide a reset force for the placing table 12; wherein the elastic force of the reset spring is not sufficient to overcome the gravity of the egg body 24 and prevent the placing table 12 from descending.

[0047] On the premise of setting up two sets of multi-link mechanisms 14, in one of the first vertical connecting plates 14-7 and the second vertical connecting plates 14-8 close to the vertical plate 18, a cross bar can be set between the two first vertical connecting plates 14-7 or the two second vertical connecting plates 14-8, and the transmission rack 16 is set in the middle position of the cross bar to ensure that the two sets of multi-link mechanisms 14 simultaneously drive the transmission rack 16 to reciprocate in the horizontal direction, avoiding the situation where the thrust of the two sets of multi-link mechanisms 14 drive the gear shaft 17 to start to rotate, resulting in horizontal deflection of the storage table 12, thereby improving the stability of the measuring device during the measurement process.

[0048] An indicator plate 23 is also provided on the side of the vertical plate 18 away from the supporting platform, and scale lines 25 are provided on the indicator plate 23. When the major axis detection device 3 and the minor axis detection device 2 move in the horizontal direction and the vertical direction, the scale lines 25 indicated by the indicating structures of the major axis detection device 3 and the minor axis detection device 2 on the indicator plate 23 change accordingly, thereby determining the change amount of the movement of the major axis detection device 3 and the minor axis detection device 2, and obtaining the major axis size and the minor axis size of the egg body 24 through the change amount.

[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 through the vertical plate slide rail 19. The long axis detection rod 20 is provided with teeth on the side facing the gear shaft 17, and the teeth are engaged with the gear on the gear shaft 17. After the egg body 24 is placed on the storage platform 12, the storage platform 12 is lowered, and the gear on the gear shaft 17 is driven to rotate through the transmission rack 16. The gear drives the long axis detection rod 20 to move along the vertical plate slide rail 19 toward the storage platform 12 through the teeth on the long axis detection rod 20. The long axis detection rod 20 is provided on one end facing the support platform. The long axis baffle 21, the long axis detection rod 20 pushes the egg body 24 placed on the slide 9 to move toward the platform baffle 8 through the long axis baffle 21 until the egg body 24 abuts against the platform baffle 8, at which time the long axis detection rod 20 stops moving and the storage table 12 stops descending; a long axis detection pointer 22 is set at the other end of the long axis detection rod 20. In the process of the long axis detection rod 20 pushing the egg body 24 to move 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 numerical difference represented by the scale line 25 indicated by the long axis detection pointer 22 before and after the measurement is the long axis size of the egg body 24.

[0050] Please refer to Figure 4, the 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, a plurality of short axis limiting rings 26 are arranged on the vertical direction of the vertical plate 18, and the short axis limiting ring 26 and the long axis detection device 3 are arranged on the opposite side of the vertical plate 18, the short axis limiting rod 5 is slidably arranged in the short axis limiting ring 26, the short axis detection plate 4 is detachably connected to one end of the short axis detection rod 6 facing the storage table 12, and the short axis detection plate 4 is located directly above the storage table 12, when measuring the size of the egg body 24, the short axis detection plate 4 and the short axis detection rod 6 need to be separated to prevent the egg body 24 or the clamping claw 10 from hindering the short axis detection rod 6 from sliding down;

[0051] After the egg 24 is placed on the placing table 12, the placing table 12 descends. When the placing table 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 9, so as to determine the reference of the short axis detection rod 6 when moving in the vertical direction; the end of the short axis detection rod 6 away from the placing table 12 is bent toward the direction of the base 1, and a short axis detection pointer 7 is provided at the bent end. The change of the scale line 25 indicated by the short axis detection pointer 7 on the indicator plate 23 reflects the change of the short axis detection device 2 in the vertical direction, and then the short axis size of the egg 24 is determined.

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

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

[0054] S2: placing the egg 24 on the storage table 12, and making one end of the long axis of the egg 24 contact the platform baffle 8, and then limiting the egg 24. Under the action of the gravity of the egg 24, the storage table 12 descends, and drives the long axis baffle 21 to move toward 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 storage table 12, it is necessary to manually control the egg 24 to maintain abutment with the platform baffle 8. Therefore, a slide rail 11 is provided on the storage table 12, and 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, and the slide table 9 can slide along the slide rail 11. After the egg 24 is placed on the slide table 9, there is no need to control the egg 24 to abut against the platform baffle 8. Under the action of the gravity of the egg 24, the storage table 12 descends, and the long axis baffle 21 pushes the egg 24 to slide on the slide rail until the egg 24 abuts against the platform baffle 8. At the same time, in order to prevent the egg 24 from sliding 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, and insert the short axis limit rod 5 into the short axis limit ring 26, the short axis detection rod 6 falls to the same height as the storage table 12, and record the indication a1 of the short axis detection pointer 7 on the vertical axis of the indicator plate 23 at this moment;

[0057] S4: lift the short axis limit rod 5 again, fix the short axis detection plate 4 on the short axis detection rod 6, and let the short axis limit rod 5 fall in the short axis limit ring 26 again.
