Description

Technical Field

[0001] This utility model relates to the field of non-destructive testing technology for eggshell thickness, specifically a non-destructive testing device for eggshell thickness based on ultrasonic technology. Background Technology

[0002] Eggshell thickness is one of the key indicators in poultry egg grading, hatching quality assessment and breakage rate control. To accurately obtain eggshell thickness without damaging the egg, ultrasonic non-destructive testing technology is usually used.

[0003] Chinese Patent Publication No. CN202321651597.7, published on February 13, 2024, discloses a non-destructive testing device for eggshell thickness based on ultrasonic technology. The device includes an equatorial detection module and two end detection modules. These modules can be used in combination to meet the thickness testing needs of different parts of the eggshell. A protective component is provided on the equatorial detection module, significantly improving the stability of the device, protecting the eggs from damage, and making it suitable for different types of eggs. A connecting component is provided at the bottom of the end detection modules, improving the compatibility between the two modules.

[0004] Although the above-mentioned technical solution uses an ultrasonic probe to contact the outer surface of the eggshell and calculates its thickness by detecting the propagation time of ultrasonic waves inside the eggshell, it has some drawbacks. For example, it can only test one egg at a time, and after testing, the next egg must be removed manually. Repeated placement, operation, control, and recording affect efficiency. In order to speed up the process, manual operation is prone to errors that cause eggs to fall. After each test, coupling agent needs to be manually applied to the probe. When testing in batches, the number of testing steps for eggs has to be increased, and the intensity of operation will also increase.

[0005] Therefore, a non-destructive testing device for eggshell thickness based on ultrasonic technology is needed to address the aforementioned technical deficiencies. Utility Model Content

[0006] The purpose of this invention is to provide a non-destructive testing device for eggshell thickness based on ultrasonic technology, so as to solve the problems of low testing efficiency and high operational intensity of batch testing mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a non-destructive testing device for eggshell thickness based on ultrasonic technology, comprising a testing seat and a partition. The partition is horizontally fixed inside the testing seat. A hollow column is fixedly connected to the top center of the partition. A turntable is fixed to the upper part of the hollow column. A gear ring is fixedly sleeved on the outer ring of the turntable. A steering motor is fixed to the right side of the top of the partition. A gear is fixedly sleeved on the output shaft of the steering motor. The gear meshes with the gear ring. Four sets of slots are provided inside the turntable. Three sets of steps with a concentric circular structure are machined on the inner edge of the slots. A cylinder is fixedly connected to the bottom center of the partition. A telescopic rod is fixedly assembled on the piston rod of the cylinder. The telescopic rod extends through the hollow column to the outside. A pressure plate is fixed around the telescopic rod.

[0008] As a further technical solution of this utility model, the four sides of the tablet are processed into concave arc shape, and its shape corresponds to a set of slots.

[0009] As a further technical solution of this utility model, a mounting bracket is fixedly connected to the left side of the outer wall of the detection seat, a lifting motor is fixedly connected to the bottom end of the mounting bracket, and a threaded rod is fixedly connected to the output shaft of the lifting motor.

[0010] As a further technical solution of this utility model, a threaded block is sleeved on the outside of the threaded rod, and a connecting frame is fixedly connected to the right side of the threaded block.

[0011] As a further technical solution of this utility model, an ultrasonic probe is movably connected inside the connecting frame, and a spring is fixedly connected to the bottom right side of the connecting frame. The ultrasonic probe corresponds to a set of slots in the vertical direction.

[0012] As a further technical solution of this utility model, a coupling agent box is placed at the rear of the detection seat, and a water pump is fixedly connected to the front end of the coupling agent box. The water pump is connected to a nozzle through a hose.

[0013] As a further technical solution of this utility model, a bracket is fixedly connected to the top of the partition, and a screw is fixedly connected between the bracket and the partition, with the bracket located on one side of the connecting frame.

[0014] As a further technical solution of this utility model, a support tray is placed on the top left side of the partition, and the support tray is located below the ultrasonic probe.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the device is equipped with four sets of slots, each set with three concentric steps on the inner side, to adapt to different egg shapes and sizes. With the help of the pressing plate, the eggs are prevented from shifting during rotation. The turntable rotates and changes position under the drive of gears and motors. With the action of the cylinder and telescopic rod, each set of eggs can stably enter the detection position, improving detection efficiency and reducing drops caused by human error.

[0016] When an egg is placed in the leftmost slot and enters the detection position, the ultrasonic probe is placed against the eggshell to detect its thickness. A spring provides stable pressure to ensure a clear and reliable signal. After the detection is completed, the lifting motor drives the threaded rod to move the entire probe assembly down, and the turntable rotates to the next egg position. The system realizes automatic switching and continuous detection of multiple eggs, avoiding damage to the eggshell caused by manual operation.

[0017] After each set of four egg tests is completed, the coupling agent box delivers coupling agent to the nozzle via a water pump, which is automatically sprayed onto the probe surface to ensure good acoustic coupling conditions before each test. The splashed coupling agent is collected and recycled through a tray, which is suitable for high-frequency batch testing needs. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4This utility model provides an embodiment of a non-destructive testing device for eggshell thickness based on ultrasonic technology, comprising a testing base 1 and a partition 18. The partition 18 is horizontally fixed inside the testing base 1. A hollow column 8 is fixedly connected to the top center of the partition 18. A turntable 4 is fixed to the upper part of the hollow column 8. A gear ring 9 is fixedly sleeved on the outer ring of the turntable 4. A steering motor 3 is fixed to the right side of the top of the partition 18. The steering motor 3 is model AZM24AK-K. The turntable 4 has a lightweight structure and a small load. The steering motor 3 has a built-in positioning feedback function, facilitating... To achieve fixed-point stopping of the turntable 4 and ensure that the probe corresponds to the slot 5, the output shaft of the steering motor 3 is fixedly sleeved with a gear 2, which meshes with the gear ring 9. The turntable 4 is equipped with four sets of slots 5, and the inner edge of the slot 5 is machined with three sets of steps in a concentric circle structure. The bottom center of the partition plate 18 is fixedly connected to a cylinder 19, and the piston rod of the cylinder 19 is fixedly equipped with a telescopic rod 7. The telescopic rod 7 extends through the hollow column 8 to the outside. A pressure plate 6 is fixed around the telescopic rod 7. The four sides of the pressure plate 6 are machined into concave arc shapes, and its shape corresponds to a set of slots 5.

[0025] Specifically, such as Figure 1 and Figure 2 As shown, each of the four sets of slots 5 can hold poultry eggs, and the inner edge of each set of slots 5 is machined with three sets of concentric steps to place poultry eggs of different sizes. After placing four sets at once, the cylinder 19 drives the telescopic rod 7 to pull back, so that the pressure plate 6 is above the poultry eggs but does not contact them, thus preventing them from falling. The detection position is the leftmost set of slots 5 on the inner wall of the detection seat 1. During detection, the pressure plate 6 is raised, the steering motor 3 is started, and the rotation of the gear 2 drives the gear ring 9 that meshes with it to rotate, and the entire turntable 4 rotates to switch to the next set of poultry eggs for detection. Then the pressure plate 6 is lowered again, which improves the detection efficiency and avoids the poultry eggs falling during rotation due to instability when manually placing them.

[0026] A mounting bracket 10 is fixedly connected to the left side of the outer wall of the detection base 1. A lifting motor 13 is fixedly connected to the bottom of the mounting bracket 10. The lifting motor 13 is an AC servo motor, which can achieve stable lifting within a range of 5-10cm. It is equipped with an encoder to achieve high-precision position control and avoid excessive contact between the probe and the eggshell. A threaded rod 12 is fixedly connected to the output shaft of the lifting motor 13. A threaded block 11 is sleeved on the outside of the threaded rod 12. A connecting bracket 14 is fixedly connected to the right side of the threaded block 11. An ultrasonic probe 15 is movably connected inside the connecting bracket 14. A spring 16 is fixedly connected to the bottom right side of the connecting bracket 14. The ultrasonic probe 15 corresponds to a set of slots 5 in the vertical direction.

[0027] Specifically, such as Figure 1 and Figure 4As shown, during testing, the eggs in the leftmost slot 5 are placed on and in contact with the ultrasonic probe 15. The spring 16 ensures that the ultrasonic probe 15 rebounds and contacts the eggs after being pressed. The eggshell thickness is detected by ultrasonic technology. After the test is completed, the lifting motor 13 drives the threaded rod 12 to rotate, and the threaded block 11 descends. The ultrasonic probe 15 descends, making it easy for the turntable 4 to change position to test the next group of eggs. This achieves automatic testing without having to hold the ultrasonic probe 15, avoiding the problem of crushing the eggs by hand or excessive contact with the eggs, which could cause the eggshells to crack.

[0028] A coupling agent box 21 is placed inside the rear of the detection seat 1. A water pump 20 is fixedly connected to the front end of the coupling agent box 21. The water pump 20 is of model GB-K23.LF and has good self-priming ability. It is compatible with a hose. The water pump 20 is connected to a nozzle 24 through a hose. A bracket 23 is fixedly connected to the top of the partition 18. A screw 22 is fixedly connected between the bracket 23 and the partition 18. The bracket 23 is located on one side of the connecting frame 14. A support tray 17 is placed on the left side of the top of the partition 18. The support tray 17 is located below the ultrasonic probe 15.

[0029] Specifically, such as Figure 1 and Figure 3 As shown, after every four groups of eggs are tested, the threaded block 11 drives the connecting frame 14 to descend once, and the coupling agent in the coupling agent box 21 is extracted and sprayed onto the surface of the ultrasonic probe 15 through the nozzle 24. The tray 17 is used to collect the sprayed coupling agent. By automatically spraying the coupling agent, there is no need for manual repeated application to the ultrasonic probe 15, which reduces the workload of manual batch testing.

[0030] Working principle: The operator places four eggs sequentially into the four slots 5 on the turntable 4. The inner edge of each slot 5 has three sets of concentric stepped structures, which automatically limit and position the eggs according to their shell size, ensuring stable placement. At this time, cylinder 19 drives the telescopic rod 7 upwards, causing the pressure plate 6 to approach the egg from above without making contact, forming a limiting structure to prevent the egg from falling during rotation. Then, ultrasonic testing begins. The pressure plate 6 lifts, releasing the egg in the testing position. The lifting motor 13 starts, driving the threaded rod 12 to rotate via its output shaft, pushing the threaded block 11 up and down. This drives the connecting frame 14 to slowly lower the ultrasonic probe 15. Under the action of spring 16, the ultrasonic probe 15 lightly touches the outer surface of the egg, automatically completing the contact. After the ultrasonic probe 15 has finished contacting, the water pump 20 is started, and the water is then... The coupling agent is extracted from the coupling agent box 21 and sprayed quantitatively onto the contact surface of the ultrasonic probe 15 through the nozzle 24 to ensure the quality of sound wave coupling. Excess coupling agent is recovered by the lower tray 17 to avoid contaminating the device or wasting liquid. After the probe makes good contact with the eggshell surface, the ultrasonic system starts, emits sound wave signals, penetrates the eggshell and receives the internal echo, and calculates the eggshell thickness by time difference. After the test is completed, the lifting motor 13 starts again, driving the ultrasonic probe 15 to rise slowly and detach from the egg. Then, the cylinder 19 drives the pressure plate 6 to rise, and at the same time, the steering motor 3 starts, driving the gear ring 9 meshing with it to rotate through the output gear 2, so that the turntable 4 rotates to a fixed angle, and the next egg is turned into the test position. The pressure plate 6 then descends again, and the above process is repeated to complete the test of four sets of eggs in sequence.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
