Technical Field

[0001] This utility model relates to the field of strength testing equipment technology, and in particular to an eggshell strength testing device. Background Technology

[0002] Eggshell quality is a very important indicator for measuring the quality of eggs produced by breeder hens and laying hens. It is closely related to the hatching rate, hatchability, and chick quality of breeding eggs, as well as the fresh egg production and economic benefits of commercial laying hens. Among them, eggshell strength is an important indicator of eggshell quality. Eggshell strength refers to the degree of pressure resistance of the eggshell, and pressure sensors are usually used to test eggshell strength.

[0003] An automatic eggshell strength tester with authorized publication number CN219830591U includes a base with an input / output device embedded in it, a rotating assembly installed inside the base, an electric slide assembly fixed to the top of the base, a pressure arm fixed to the slider of the electric slide assembly, a pressure column screwed to the bottom of the pressure arm, a pressure plate attached to the bottom of the pressure column, an upper pressure transmitter between the pressure plate and the pressure column, and a test platform fixed to the top surface of the base opposite the pressure column. This automatic eggshell strength tester can perform constant pressure testing and destructive testing on eggshells, and can also monitor cracks in eggshells after pressure is applied.

[0004] Regarding the aforementioned technologies, the existing strength testing equipment has the following drawbacks: dust adheres to the surface of the egg during storage and transportation, and dust particles form uneven "rigid protrusions" between the pressure head and the eggshell surface, resulting in a reduction in the local contact area and affecting the testing accuracy. Therefore, this utility model provides an eggshell strength testing device. Utility Model Content

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.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Example 1: Reference Figure 1-4The eggshell strength testing device shown includes a support frame 1. An inverted funnel-shaped groove 2 is provided on the inner side of the support frame 1 to facilitate the collection of eggshell breakage residue during testing. The funnel-shaped design allows the residue to fall smoothly and is easy to clean later. A rotating rod 7 is installed through the inner side of the support frame 1, allowing it to rotate within the frame. This provides a mounting base for a dust blowing assembly, a cleaning assembly, and an ion neutralization assembly, and drives them in circular motion, expanding the effective range of each assembly. A dust blowing assembly, a cleaning assembly, and an ion neutralization assembly are located on the outer side of the rotating rod 7. The dust blowing assembly includes a first fixing plate 8 fixedly connected to the outer side of the rotating rod 7. The first fixing plate 8 is used to fix an air pump 9, ensuring its stability during operation. The air pump 9, which generates compressed air, provides the power source for the air jet. A jet nozzle 10 is located below the first fixed plate 8. The output end of the air pump 9 is connected to the jet nozzle 10. The jet nozzle 10 can directionally spray the compressed air output by the air pump 9 to blow away dust and other light debris from the eggshell surface, preventing dust from affecting the accuracy of the eggshell strength test. The cleaning assembly includes a second fixed plate 11 fixedly connected to the outside of the rotating rod 7. The second fixed plate 11 is used to install the hydraulic push rod 12, enabling the hydraulic push rod 12 to work stably. The hydraulic push rod 12 is installed through the inner side of the second fixed plate 11. The hydraulic push rod 12 can adjust the distance between the brush plate 14 and the eggshell surface through telescopic movement to adapt to eggshells of different sizes. A motor 13 is fixedly connected to the output end of the hydraulic push rod 12. The motor 13 can drive the brush plate 14 to rotate, cleaning the eggshell surface and removing firmly attached impurities such as dust and stains. A brush plate 14 is fixedly connected to the output end of motor 13. The bristles on the brush plate 14 can directly contact the eggshell surface and clean impurities through friction. The ion neutralization assembly includes a third fixing plate 18 fixedly connected to the outside of the rotating rod 7. The third fixing plate 18 is used to fix the fixing frame 19 to ensure the overall structural stability of the ion neutralization assembly. The bottom of the third fixing plate 18 is fixedly connected to the fixing frame 19. Multiple ion fans are installed inside the fixing frame 19. The ion fans can generate airflow with positive and negative ions to neutralize the static electricity on the eggshell surface and prevent static electricity from attracting dust and affecting the test. The air outlet of the fixing frame 19 is provided with multiple tungsten needles arranged in an array. The tungsten needles can enhance the emission efficiency of ions, make the ions more evenly distributed on the eggshell surface, and improve the static electricity neutralization effect. The inner wall side of the fixing frame 19 is provided with a vent plate 20. The vent plate 20 can guide the airflow generated by the ion fans, so that the airflow can be discharged more smoothly from the air outlet, ensuring that the ions can fully contact the eggshell surface.

[0020] Example 2: Reference Figure 1-4Based on the same concept as Embodiment 1 above, this embodiment further proposes that a dust collector 3 be installed on the outer side of the support frame 1. The dust collector 3, by generating negative pressure suction, can effectively collect dust, debris, and other impurities generated during operation, preventing them from spreading into the working environment and affecting work quality and operator health. A dust collection pipe 4 is fixedly connected to the output end of the dust collector 3. The dust collection pipe 4 serves as a channel connecting the dust collector 3 to subsequent components, transmitting the suction power generated by the dust collector 3 to a designated location. A ventilation ring 5 is installed inside the empty slot 2. The ventilation ring 5 evenly distributes the suction power, ensuring that the entire annular area has dust collection capability. The dust collection pipe 4 is connected to the ventilation ring 5, ensuring that the suction power can be smoothly transmitted to the ventilation ring 5. Multiple interconnected dust extraction heads 6 are fixedly connected to the outer side of the ventilation ring 5. These heads directly contact the working area, sucking in dust and debris. The multiple extraction heads 6 expand the dust extraction range and improve efficiency. A placement plate 22 is installed inside the empty trough 2 to hold items to be processed or handled. Multiple placement slots 23 allow for categorized placement of items, facilitating management and operation. A load-bearing rod 24 is fixedly connected to the bottom of the placement plate 22, and is also fixedly connected to the inner wall of the empty trough 2. The load-bearing rod 24 enhances the load-bearing capacity of the placement plate 22, ensuring its stability when carrying items and preventing deformation or damage. A motor 21 is installed at the bottom of the support frame 1, providing power to the rotating rod 7, which rotates through its output end. The output end of the electric motor 21 is fixedly connected to the rotating rod 7 to achieve direct power transmission. A positioning plate 16 is fixedly connected to the outer side of the rotating rod 7. The positioning plate 16 provides an installation position for the hydraulic telescopic rod 17 and drives the hydraulic telescopic rod 17 to rotate synchronously when the rotating rod 7 rotates, thus playing the role of positioning and power transmission. The hydraulic telescopic rod 17 is installed through the inner side of the positioning plate 16. The hydraulic telescopic rod 17 can adjust the height position of the lifting plate 15 through its telescopic movement to meet different working requirements. The output end of the hydraulic telescopic rod 17 is fixedly connected to the lifting plate 15, which is used to bear and transmit pressure. Multiple pressure sensors 25 are installed at the bottom of the lifting plate 15. The pressure sensors 25 can monitor the pressure on the lifting plate 15 in real time and feed the pressure data back to the control system for corresponding adjustments and control.

[0021] The working principle of this utility model is as follows: An egg is placed in the placement tank 23. The air pump 9 sprays high-pressure gas through the jet nozzle 10 to blow away dust from the outside of the eggshell. The dust extractor 3 extracts dust through the dust extraction pipe 4, ventilation ring 5, and multiple dust extraction heads 6. The motor 21 drives the rotating rod 7 to rotate, causing the brush plate 14 to deflect directly above the placement plate 22. The motor 13 drives the brush plate 14 to rotate, and the hydraulic push rod 12 drives the motor 13 downwards to clean the eggshell surface again. The motor 21 continues to rotate, energizing multiple tungsten needles to generate positive and negative ions. The ion fan blows ionized air through the ventilation plate 20, evenly covering the entire eggshell surface. The neutralization time is ≤3 seconds, neutralizing surface static electricity. The motor 21 continues to rotate, moving the lifting plate 15 directly above the placement plate 22. The hydraulic telescopic rod 17 drives the lifting plate 15 and pressure sensor 25 downwards to detect pressure on the eggshell.
