The egg testing items generally include fresh egg crack detection and preserved egg pickling quality detection. These test items are often tested through sound wave detection technology, that is, the receiving microphone receives and analyzes the reflected waves and transmitted waves, etc., and the frequency changes and vibration frequencies of the sound waves are used to determine whether the fresh eggs have cracks or whether the preserved eggs are well pickled.

[0003] In the existing related technologies, reference can be made to the invention patent with publication number CN 116148357 A. The invention patent discloses an automatic detection and classification system and method for egg cracks that can be accurately sorted, including obtaining environmental sounds in a state where the eggs are not struck; in a state where the eggs are struck, the cracked eggs and the crackless eggs are struck respectively, and a first composite sound including environmental sounds and the sound of striking the eggs is obtained at a first position; a second composite sound including environmental sounds and the sound of striking the eggs is obtained at a second position, wherein the second position is farther from the source of the sound of striking the eggs than the first position; the frequency range of the sound of striking the eggs without cracks and the frequency range of the sound of striking the eggs with cracks are screened out according to the environmental sounds, the first composite sound and the second composite sound; the eggs to be detected are numbered, and the time distribution of the hammer striking the eggs is controlled, so that the egg crack detection can be quickly realized.

[0004] With regard to the above-mentioned related technologies, when eggs are inspected by striking the top of the egg with a hammer and then receiving and analyzing the sound waves with a receiving microphone on the top of the egg, the egg needs to stop at the position of the hammer to facilitate the hammering, and the inspection efficiency needs to be improved. Summary of the invention

[0005] In order to improve the efficiency of egg detection, the present application provides an egg quality detection device.

[0006] The egg quality detection device provided in this application adopts the following technical solution: An egg quality detection device comprises a frame, a pushing component and a detection component; The detection assembly includes a detection slide rail, a detection corrugated plate and an acoustic wave detection member; The detection slide rail is installed on the frame, and the detection slide rail is provided with a detection slide groove, and the detection slide groove extends along the length direction of the detection slide rail; the detection corrugated plate is installed on the frame, and the detection corrugated plate is provided with a detection protrusion, and the detection protrusion is located in the detection slide groove; the sound wave detection element is used to receive and analyze the sound waves generated when the egg rolls over the detection protrusion; The pushing component is used to push the eggs to move along the extension direction of the detection chute.

[0007] By adopting the above technical solution, the eggs are placed in the detection chute, and then the eggs are pushed to move along the extension direction of the detection chute by the pushing component. After the eggs contact the detection protrusion, sound waves are generated, and the sound waves are received and analyzed by the sound wave detection component, and then it is judged whether there are cracks in the fresh eggs or whether the preserved eggs are well pickled, so as to detect the quality of the eggs. During the entire detection process, the eggs have almost no pauses, and only need to move continuously along the detection chute, and the detection efficiency is high. In addition, it is also helpful to reduce the occurrence of cracks in the brittle shells of thin-shell eggs or pickled eggs due to hammer strikes.

[0008] Optionally, a plurality of the detection protrusions are provided, and the plurality of the detection protrusions are distributed along the extension direction of the detection slide groove.

[0009] By adopting the above technical solution, the eggs contact and pass through each detection protrusion in turn, thereby continuously generating sound waves for the sound wave detection element to receive and analyze, which is conducive to improving the detection accuracy.

[0010] Optionally, the detection corrugated plates are provided in plurality, and the plurality of the detection corrugated plates are divided into two groups, and the two groups of the detection corrugated plates are distributed along the extension direction of the detection chute; The detection protrusions of one group of the detection corrugated plates are arranged close to one side of the detection slide groove along the width direction of the detection slide groove, and the detection protrusions of the other group of the detection corrugated plates are arranged close to the other side of the detection slide groove along the width direction of the detection slide groove.

[0011] By adopting the above technical solution, when the eggs move along the detection chute, one end of the eggs first contacts the detection protrusions of one set of detection corrugated plates, and the sound wave detection component receives and analyzes the sound waves generated by one end of the eggs.

[0012] After one end of the egg is tested, it contacts the testing protrusions of another set of testing corrugated plates, and the sound wave testing component receives and analyzes the sound waves generated by the other end of the egg.

[0013] Therefore, by testing the two ends of the egg in sequence, the sound waves generated at the two ends of the egg are less likely to interfere with each other, which is beneficial to improving the detection accuracy.

[0014] Optionally, the acoustic wave detection member is located at the bottom of the detection corrugated plate.

[0015] By adopting the above technical solution, it is helpful to reduce the interference of irrelevant environmental sound waves on the sound wave detection element. In addition, compared with the method of setting the sound wave detection element on the top or side of the detection corrugated plate, the sound wave detection element is less likely to cause obstruction and inconvenience to the transportation of eggs.

[0016] Optionally, the detection component further includes a receiving seat; The receiving seat is provided with a seat body accommodating groove, the notch of the seat body accommodating groove faces the detection corrugated plate from bottom to top, and the sound wave detection component is located in the seat body accommodating groove.

[0017] By adopting the above technical solution, the sound waves generated when the eggs contact and pass through the detection protrusion are directly transmitted to the sound wave detection component through the notch of the seat accommodating groove, making it difficult for the sound wave detection component to receive irrelevant environmental sound waves, thereby facilitating improving the detection accuracy.

[0018] Optionally, the receiving seat is mounted on the frame via a seat buffer, and the seat buffer is elastic.

[0019] By adopting the above technical solution, the vibration generated when the egg contacts and passes through the detection protrusion, as well as the vibration generated when the detection device is running, will be absorbed by the seat buffer, making the acoustic wave detection element less susceptible to the vibration, thereby facilitating improved detection accuracy.

[0020] Optionally, the pushing assembly includes an egg pushing member and a rotary driving member; There are a plurality of egg pushers, and the rotary drive member is used to drive each egg pusher to perform circumferential motion.

[0021] By adopting the above technical solution, a plurality of egg pushers respectively and sequentially push a plurality of eggs to move along the detection chute, which is beneficial to improving the egg conveying and detection efficiency.

[0022] Optionally, the rotary drive member includes a rotary sprocket and a rotary chain; The rotary sprocket is rotatably matched with the frame, the rotary chain is wound around the rotary sprocket, and a plurality of egg pushers are installed on the rotary chain, and the plurality of egg pushers are distributed along the length direction of the rotary chain.

[0023] By adopting the above technical solution, the rotary chain occupies a small volume and is convenient for layout and installation, thereby facilitating the transportation and inspection of a larger number of eggs with a limited device volume.

[0024] Optionally, the egg quality detection device further comprises a rejection component; The reject assembly includes a reject slide rail, an opening and closing member, and a reject conveyor belt; The reject slide rail is installed on the frame, and the reject slide rail is provided with a reject slide slot and a reject drop slot, the reject slide slot is connected to the detection slide slot, and the reject drop slot is penetrated and opened at the bottom of the detection slide slot; the opening and closing member is used to open and close the reject drop slot; The reject conveyor belt is located at the bottom of the reject chute.

[0025] By adopting the above technical solution, when the ultrasonic detection component detects eggs of unqualified quality, the position sequence of the eggs is recorded. When the eggs move along the rejection chute to the rejection chute, the opening and closing component opens the rejection chute, allowing the unqualified eggs to fall to the bottom of the conveyor belt, thereby rejecting the unqualified eggs.

[0026] Optionally, the egg pushing member includes a mounting seat and an egg pushing rod; The egg pushing rods are provided with a plurality of egg pushing rods, and egg pushing grooves are provided between the plurality of egg pushing rods. The egg pushing grooves are used to accommodate eggs. The egg pushing rods are rotatably matched with the mounting seat, and a pushing rod reset piece is provided between the egg pushing rods and the mounting seat, and the pushing rod reset piece is elastic.

[0027] By adopting the above technical solution, the egg push rod is always tightly fitted to the surface of the egg under the action of the push rod reset member. When the egg contacts and passes the detection protrusion, the egg push rod rotates with the rise and fall of the egg and keeps the egg in a limited position, so that the egg is not likely to bounce up after contacting the detection protrusion and pass over the detection protrusion without generating enough sound waves for the sound wave detection member to receive and analyze, thereby ensuring the egg conveying stability and detection accuracy.

[0028] In summary, the present application includes at least one of the following beneficial technical effects: 1. Place the eggs on the detection chute, and then use the pushing component to push the eggs along the extension direction of the detection chute. When the eggs touch the detection protrusion, sound waves are generated. The sound waves are received and analyzed by the sound wave detection component to determine whether there are cracks in the fresh eggs or whether the preserved eggs are well pickled, thereby detecting the quality of the eggs. During the entire detection process, the eggs have almost no pauses and only need to move continuously along the detection chute, so the detection efficiency is relatively high. In addition, it is also helpful to reduce the occurrence of cracks in the brittle shells of thin-shelled eggs or pickled eggs due to hammering; 2. When the egg moves along the detection chute, one end of the egg first contacts the detection protrusion of one set of detection corrugated plates, and the sound wave detection component receives and analyzes the sound waves generated by one end of the egg. After one end of the egg is detected, it contacts the detection protrusion of another set of detection corrugated plates, and the sound wave detection component receives and analyzes the sound waves generated by the other end of the egg. Therefore, by detecting both ends of the egg in turn, the sound waves generated by both ends of the egg are not easy to interfere with each other, which is conducive to improving the detection accuracy; 3. The egg push rod is always tightly fitted to the surface of the egg under the action of the push rod reset member. When the egg contacts and passes the detection protrusion, the egg push rod rotates with the rise and fall of the egg and keeps the egg in position, so that the egg is not likely to bounce up after contacting the detection protrusion and pass over the detection protrusion without generating enough sound waves for the sound wave detection member to receive and analyze, thereby ensuring the egg transportation stability and detection accuracy.

After the eggs contact the detection protrusion 331, sound waves are generated, which are received and analyzed by the sound wave detection member 34 to determine whether there are cracks in the fresh eggs or whether the preserved eggs are well pickled, thereby detecting the quality of the eggs. During the entire detection process, the eggs have almost no pauses and only need to move continuously along the detection chute 311, so the detection efficiency is relatively high.
