Description

Technical Field

[0001] The utility model relates to the technical field of eggs, in particular to an egg size screening device. Background Art

[0002] Eggs, also known as chicken eggs, are the eggs produced by hens. They have a hard shell on the outside and an air chamber, egg white and egg yolk inside. They are rich in protein and various trace elements and are nutritious. In the process of egg production, processing and sales, grading eggs by size is an important link to improve the added value of products and meet market demand.

[0003] The existing utility model of an automatic egg grading device with the authorization announcement number of CN209268355U includes a screening tank. The top and both sides of the screening tank are open. A plurality of partition plates are fixedly connected to the bottom inner wall of the screening tank. A support rod is welded to the bottom of the screening tank. A rotating shaft is welded to one side of the support rod. A balance rod is rotatably sleeved outside the rotating shaft. A rubber ball is fixedly pasted on one side of the top of the balance rod. The rubber ball cooperates with the screening tank. A driving motor is fixedly connected to the bottom of the screening tank. The driving motor is located on the side of the support rod away from the rubber ball. A turntable is fixedly sleeved on the output shaft of the driving motor.

[0004] Adopting this technical solution, the design is reasonable and the structure is simple. Under the driving action of the driving motor, the rubber ball can continuously knock on the bottom of the screening tank, causing the eggs in the screening tank to vibrate, which is beneficial to the eggs to roll in the screening tank and can screen the eggs according to their sizes. However, in the process of screening the egg sizes, the eggs are constantly moving. For eggs with thinner shells, the eggs are easily damaged during the rolling process in the screening tank, which not only reduces the screening efficiency of the device, but also causes waste of eggs and further reduces the screening efficiency of the device.

The outer surface of each block 20 is engaged with the inside of the card slot 22. The outer surface of each electric push rod 21 is sleeved with a buffer spring 18.

[0026] By the telescopic movement of the electric push rod 21, under the buffering action of the buffer spring 18, the block 20 and the card slot 22 are separated, realizing the rapid replacement of the second screening plate 19 and the first screening plate 23, and further improving the use effect and working efficiency of the device.

[0027] Further, a fixed frame 7 is fixedly connected to the outer surface of the controller 6. The bottom surface of the fixed frame 7 is fixedly connected to the upper surface of the bottom plate 1. The controller 6 is electrically connected to the electric push rod 21, the servo motor 10, and the telescopic rod 3 through wires. One end of a set of buffer springs 18 away from each other is fixedly connected to the outer surface of the block 20 and the inner wall of the first screening frame 8 respectively, and one end of the other set of buffer springs 18 away from each other is fixedly connected to the outer surface of the block 20 and the inner wall of the second screening frame 9 respectively.

[0028] Further, an L-shaped plate 11 is fixedly connected to the outer surface of the servo motor 10. The left side surface of the L-shaped plate 11 is fixedly connected to the right side surface of the fixed frame 2.

[0029] Further, a bearing 16 is fixedly connected to the outer surface of the lead screw 14. The outer surface of the bearing 16 is fixedly connected to the inner wall of the sliding groove 15.

[0030] Further, a fixed ring 12 is fixedly connected to the outer surface of each telescopic rod 3. The bottom end of the fixed ring 12 is fixedly connected to the upper surface of the second screening frame 9.

[0031] Further, two groups of bolts 5 are threadedly connected to the inner wall of the bottom plate 1. Two gaskets 4 are sleeved on the outer surface of each group of bolts 5. The bottom end of each gasket 4 is in contact with the upper surface of the bottom plate 1.

[0032] Further, two trapezoidal blocks 25 are fixedly connected to the front surface and the back surface of the first screening frame 8 respectively. The bottom surface of each trapezoidal block 25 is fixedly connected to the upper surface of the bottom plate 1.

[0033] Further, a fixed shell 24 is fixedly connected to the outer surface of each electric push rod 21. The outer surface of each fixed shell 24 is fixedly connected to the outer surface of the block 20.

[0034] Working principle: When in use, first connect the controller 6, electric push rod 21, servo motor 10, and telescopic rod 3 to the power supply. When using this device to screen eggs, the staff uses the controller 6 to control the servo motor 10 to work. The servo motor 10 drives the lead screw 14 to rotate when it works. The rotation of the lead screw 14 drives the slider 13 to slide along the inside of the chute 15. During the movement of the slider 13, it drives the first screening mechanism composed of the telescopic rod 3, the second screening rack 9, and the second screening plate 19 to move directly above the first screening rack 8. According to the size of the egg specifications, the staff replaces the specifications of the second screening plate 19 and the first screening plate 23. When it is necessary to replace the second screening plate 19 and the first screening plate 23, use the controller 6 to control the electric push rod 21 to work. The electric push rod 21 drives the clamping block 20 to stretch under the support of the U-shaped frame 17 and disengages from the card slots 22 of the second screening plate 19 and the first screening plate 23 under the buffering action of the buffer spring 18. The staff takes out and replaces the first screening plate 23 and the second screening plate 19. Then use the controller 6 to control the electric push rod 21 to reset. Then use the controller 6 to control the telescopic rod 3 to lift and drive the second screening rack 9 and the second screening plate 19 to contact the upper surface of the first screening rack 8. Then the staff places the eggs to be screened on the upper hole surface of the second screening plate 19. Then the smaller eggs will leak through the holes of the second screening plate 19 and fall into the inside of the first screening plate 23. At this time, the staff uses the controller 6 to control the telescopic rod 3 to work. The telescopic rod 3 stretches and drives the eggs on the second screening rack 9 and the second screening plate 19 to move upward from the first screening plate 23. The eggs that meet the specifications of the second screening plate 19 are lifted by the second screening plate 19 and stored on the upper surface of the second screening plate 19. The eggs of smaller specifications stay inside the first screening plate 23. Then use the controller 6 to control the servo motor 10 to work. The servo motor 10 drives the lead screw 14 to rotate when it works. The rotation of the lead screw 14 drives the slider 13 to move along the inside of the chute 15, realizing the reset of the telescopic rod 3, the second screening rack 9, and the second screening plate 19, thus facilitating the staff to take and store the screened eggs. Through this device, eggs of different specifications can be quickly screened, further improving the use effect and working efficiency of the device.
