Description

Technical Field

[0001] The utility model relates to the technical field of egg crack detection by acoustic waves, in particular to an egg cracking and grading machine. Background Art

[0002] During the production process, eggs are inspected for surface cracks. Eggs with no cracks in the shell are easier to store for a long time, while eggs with severe cracks are not easy to store for a long time. Eggs are graded according to whether there are cracks and the severity of the cracks, and are used to make different types of eggs.

[0003] Traditional egg crack detection and grading machines use hammers that directly strike the eggshells. Due to the varying sizes of eggs, larger eggs are closer to the hammers, making them more susceptible to cracking. Furthermore, after 450 days of age, laying hens gradually lose their ability to absorb phosphorus, potassium, and calcium, resulting in a decrease in eggshell thickness and hardness. This also makes the eggshells more susceptible to cracking, creating a defect. Due to the numerous limitations of direct physical impact, improvements are urgently needed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides an egg detection and egg grading machine, which is used to solve the problem that the traditional egg crack detection and egg grading machine uses a hammer head to directly impact the eggs, which easily cracks the egg shells when the eggs are too large and the egg shell thickness is small.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] An egg inspection and egg-splitting grading machine comprises a grading conveyor and a conveyor chain on the grading conveyor for conveying eggs. A chassis is fixedly mounted on the grading conveyor and is located above the conveyor chain. A fixing frame is fixedly mounted inside the chassis. An ultrasonic generator is mounted on the fixing frame. An ultrasonic transducer is mounted below the fixing frame. A straight spring is fixedly connected to the bottom of the ultrasonic transducer.

[0007] A shaft sleeve is installed in the chassis for horizontal rotation, a knocking rod is fixedly installed on the shaft sleeve for tilting, the lower end of the knocking rod is tilted toward the downstream side of the conveying chain, the upper end of the knocking rod is connected to the lower end of the straight spring, the lower end of the knocking rod is installed with a hammer head, and a sound wave receiver is installed below the fixed frame through a connecting bracket, the sound wave receiver corresponds to the position of the hammer head and is located on one side of the egg conveying direction.

[0008] Preferably, a fixed shaft perpendicular to the conveying direction of the conveyor chain is horizontally fixedly installed in the chassis, and the shaft sleeve is rotatably connected to the surface of the fixed shaft.

[0009] Preferably, the ultrasonic transducer and the straight spring are both arranged vertically, and the ultrasonic transducer, the straight spring, the knocking rod and the egg are located in the same vertical plane.

[0010] Preferably, the hammer head is a spindle-shaped resin hammer.

[0011] Preferably, the ultrasonic transducer and the sound wave receiver are both located corresponding to the eggs and are arranged equidistantly in the transverse and longitudinal directions, and the sound wave receiver is located between two adjacent eggs in the longitudinal direction.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The utility model emits vibrations through an ultrasonic transducer, which is transmitted to a knocking rod through a straight spring to drive a hammer head to knock the eggs downward. Not only is the vibration amplitude emitted by the ultrasonic transducer extremely small, but the straight spring is elastic and retractable, so that the hammer head can easily rebound when knocking the eggs, and will not directly and hard impact the eggs to cause the eggshells to be cracked. The utility model is suitable for eggs of different sizes and eggshell thicknesses, and solves the problem that traditional egg crack detection and egg grading machines that use hammer heads for direct physical impact to knock eggs for grading are prone to cracking eggshells when the eggs are large in size and thin in eggshell thickness. The utility model also has a simple structure, is easy to maintain, is very practical, and is suitable for popularization and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-5 As shown, the utility model provides a technical solution: an egg inspection and egg grading machine, comprising a grading conveyor 1 and a conveyor chain 3 on the grading conveyor 1 for conveying eggs 2, a chassis 4 fixedly mounted on the grading conveyor 1 and located above the conveyor chain 3, a fixing frame 5 fixedly mounted inside the chassis 4, an ultrasonic generator 6 mounted on the fixing frame 5, an ultrasonic transducer 7 mounted below the fixing frame 5, and a straight spring 8 fixedly connected to the bottom of the ultrasonic transducer 7;

[0022] A shaft sleeve 9 is horizontally and rotatably installed in the chassis 4, and a knocking rod 10 is fixedly and obliquely installed on the shaft sleeve 9. The lower end of the knocking rod 10 is inclined toward the downstream side of the conveying chain 3. A fixed shaft 14 perpendicular to the conveying direction of the conveying chain 3 is horizontally and fixedly installed in the chassis 4. The shaft sleeve 9 is rotatably connected to the surface of the fixed shaft 14. The knocking rod 10 can be turned up and down around the fixed shaft 14 to allow the hammer head 11 to knock the eggs 2;

[0023] The upper end of the knocking rod 10 is connected to the lower end of the straight spring 8, and the lower end of the knocking rod 10 is equipped with a hammer head 11. The hammer head 11 is a spindle-shaped resin hammer with moderate hardness to protect the egg 2 from being broken into eggshells. The ultrasonic transducer 7 and the straight spring 8 are all vertically arranged, and the ultrasonic transducer 7, the straight spring 8, the knocking rod 10 and the egg 2 are located in the same vertical plane. When the egg 2 is transported downstream, it will automatically push the hammer head 11 upward so that it will not be hindered by the hammer head 11 and the knocking rod 10;

[0024] An acoustic wave receiver 13 is installed below the fixing frame 5 through a connecting bracket 12. The acoustic wave receiver 13 corresponds to the position of the hammer head 11 and is located on one side of the conveying direction of the eggs 2. The ultrasonic transducer 7 and the acoustic wave receiver 13 both correspond to the positions of the eggs 2 and are equidistantly arranged in the horizontal and vertical directions. The acoustic wave receiver 13 is located between two adjacent eggs 2 in the longitudinal direction, close to the hammer head 11 and will not hinder the conveyance of the eggs 2.

[0025] Working principle:

[0026] The ultrasonic generator 6 emits ultrasonic waves, which are converted into mechanical vibrations through the ultrasonic transducer 7. The vibrations are output downward through the straight spring 8, driving the knocking rod 10 and the hammer head 11 to swing up and down around the fixed axis 14 to strike the egg 2. Because the vibration amplitude generated by the ultrasonic transducer 7 is relatively small and the straight spring 8 is elastic and retractable, the hammer head 11 easily rebounds when striking the egg 2, and will not directly impact the egg 2 and cause the eggshell to be cracked.
