A detector 9 is arranged above the U-shaped support frame 1.

[0026] like Figure 1-Figure 2 As shown, a vertical plate 7 is slidably connected to the outer side of the U-shaped support frame 1, a mounting plate 8 and a first T-shaped slider 11 are fixedly arranged on the back side of the vertical plate 7, a detector 9 is fixedly installed on the top surface of the mounting plate 8, a detection end of the detector 9 is arranged on the bottom surface of the mounting plate 8, the detector 9 is electrically connected to the detection end, the detection end of the detector 9 is aimed at the eggs to obtain the image information of the eggs, so that the detector 9 can judge the quality of the eggs and identify the broken eggs, so as to realize the grading detection of the eggs, a first T-shaped groove adapted to the first T-shaped slider 11 is arranged on the outer side of the U-shaped support frame 1, the first T-shaped slider 11 is slidably connected to the U-shaped support frame 1 through the first T-shaped groove, and the moving vertical plate 7 can drive the first T-shaped slider 11 to slide inside the first T-shaped groove, thereby driving the mounting plate 8 and the detector 9 to move left and right, so as to facilitate the rapid change of the position of the detector 9.

[0027] like Figure 1-Figure 3As shown, a push assembly is arranged on the inner side of the U-shaped support frame 1, and the push assembly consists of a collecting trough 10, a rubber pad 14, a fixed plate 15, a servo motor 16, a rotating plate 17, a first electric telescopic rod 18, a second electric telescopic rod 19, a lifting plate 20 and a second T-shaped slider 21. A fixed plate 15 is fixedly arranged on the inner side of the U-shaped support frame 1, and the fixed plate 15 is arranged inside the conveyor belt 4. The servo motor 16 is fixedly installed on the top surface of the fixed plate 15, and the rotating plate 17 is fixedly installed on the top surface of the output end of the servo motor 16. The first electric telescopic rod 18 and the second electric telescopic rod 19 are fixedly installed on the top surface of the rotating plate 17, and the lifting plate 20 is hinged on the top surface of the output end of the second electric telescopic rod 19. The rubber pad 14 is fixedly arranged on the top surface of the lifting plate 20, and the lifting plate 20 moves upward and passes through the empty slot to drive the rubber pad 14 to contact The broken eggs can drive the broken eggs to move upward, and the rubber pad 14 can increase the friction between the lifting plate 20 and the eggs, thereby preventing the eggs from moving relative to the lifting plate 20 while the lifting plate 20 remains horizontal. The top surface of the output end of the first electric telescopic rod 18 is hinged with a second T-shaped slider 21, and the bottom surface of the lifting plate 20 is provided with a second T-shaped slide groove adapted to the second T-shaped slider 21. The second T-shaped slide groove is slidingly connected to the lifting plate 20 through the second T-shaped slide groove. A collecting trough 10 is fixedly installed on the outside of the U-shaped support frame 1, and the top surface of the collecting trough 10 is an inclined surface. A connecting plate is fixedly provided between the outer side surface of the U-shaped support frame 1 and the bottom surface of the collecting trough 10. The pushing assembly can drive the broken eggs to move upward along the empty groove and roll them into the inside of the collecting trough 10, thereby facilitating the broken eggs to be pushed out for collection.

[0028] Specifically, when the detector 9 identifies a broken egg, the detector 9 sends an electrical signal to the control panel 6. When the broken egg moves above the lifting plate 20, the control panel 6 controls the output ends of the first electric telescopic rod 18 and the second electric telescopic rod 19 to extend simultaneously, thereby driving the lifting plate 20 and the rubber pad 14 to move upward. The rubber pad 14 moves upward and passes through the empty slot to contact the broken egg and drive the egg to move upward. After the broken egg moves to above the U-shaped support frame 1, the control panel 6 controls the servo motor 16 to drive the rotating plate 17 to rotate ninety degrees, thereby driving the lifting plate 20, the rubber pad 14 and the egg to rotate ninety degrees. During the rotation of the egg, the relative rubber pad 14 never moves. Then the control panel 6 controls the output end of the first electric telescopic rod 18 to extend to drive the second T-shaped slider 21 to move upward. The second T-shaped slider 21 is relative to the lifting plate 20 at the second T-slide The broken eggs are rolled along the top of the rubber pad 14 to the inside of the collecting trough 10, thereby facilitating the collection of the broken eggs. After the broken eggs are separated from the rubber pad 14, the control panel 6 controls the output end of the first electric telescopic rod 18 to contract so that the lifting plate 20 returns to a horizontal state. The control panel 6 controls the servo motor 16 to drive the lifting plate 20 to rotate ninety degrees in the opposite direction. Then, the control panel 6 controls the output ends of the first electric telescopic rod 18 and the second electric telescopic rod 19 to contract simultaneously so that the lifting plate 20 moves downward back to its original position. During the up and down movement of the lifting plate 20, the pushing assembly never contacts the conveyor belt 4 and the cross bar 5.

[0029] like Figure 1-Figure 4As shown, a limiting assembly is arranged on the outside of the U-shaped support frame 1, and the limiting assembly consists of a knob 12, a threaded groove 13, a threaded rod 22, a movable plate 23, a spring 24, a first limiting ring 25 and a second limiting ring 26. A knob 12 is arranged on the outside of the U-shaped support frame 1, and a threaded rod 22 is fixedly arranged at the center of one side of the knob 12 close to the U-shaped support frame 1, a threaded hole adapted to the threaded rod 22 is penetrated through the side of the vertical plate 7, and the threaded rod 22 is threadedly connected to the vertical plate 7 through the threaded hole, a spring 24 is fixedly arranged on the side of the vertical plate 7, and a movable plate 23 is fixedly arranged on the other end of the spring 24, a first limiting ring 25 is fixedly arranged on the other side of the movable plate 23, and a second limiting ring 26 is fixedly arranged on the other side of the first limiting ring 25, and the first limiting ring 25 and the first limiting ring 25 are fixedly arranged. The inner diameter length is the same, the outer diameter length of the first limiting ring 25 is smaller than the outer diameter length of the second limiting ring 26, a hole groove is set through the central position of the movable plate 23, the threaded rod 22 passes through the movable plate 23 through the hole groove, and a first annular groove adapted to the first limiting ring 25 is set on the side of the knob 12 close to the threaded rod 22, the first limiting ring 25 is rotatably connected to the knob 12 through the first annular groove, and a second annular groove adapted to the second limiting ring 26 is set inside the knob 12, the first annular groove is communicated with the second annular groove, and the second limiting ring 26 is rotatably connected to the knob 12 through the second annular groove, the side of the movable plate 23 close to the knob 12 is rotatably connected to the knob 12, and a plurality of thread grooves 13 adapted to the threaded rod 22 are set in a linear array on the outside of the U-shaped support frame 1, and the threaded rod 22 The threaded connection with the U-shaped support frame 1 is threaded through the thread groove 13. Turning the knob 12 drives the threaded rod 22 to rotate so that the threaded rod 22 can move forward and backward relative to the vertical plate 7, thereby driving the knob 12 to move forward and backward. Turning the knob 12 so that the threaded rod 22 is threadedly connected with the U-shaped support frame 1 through the thread groove 13 can prevent the threaded rod 22 from moving relative to the U-shaped support frame 1, thereby fixing the position of the detector 9, thereby preventing the detector 9 from shaking left and right. Rotating the knob 12 in the opposite direction drives the threaded rod 22 to disengage from the U-shaped support frame 1 to release the limit on the detector 9. Moving the vertical plate 7 left and right allows the broken eggs identified by the detector 9 to be transported to the top of the rubber pad 14, so that the control panel 6 can just control the pushing assembly to push the broken eggs outward. At this time, the threaded rod 22 is aligned with the thread groove 13. Groove 13, turn the knob 12 to make the threaded rod 22 threadedly connected to the U-shaped support frame 1 through the threaded groove 13, and re-fix the position of the detector 9. The threaded rod 22 never separates from the vertical plate 7 during rotation. The knob 12 and the threaded rod 22 will not drive the movable plate 23, the spring 24, the first limiting ring 25 and the second limiting ring 26 to rotate during rotation. When the knob 12 is rotated and moves away from the vertical plate 7, the second limiting ring 26 can be driven away from the vertical plate 7, thereby driving the movable plate 23 and the first limiting ring 25 away from the vertical plate 7, and the spring 24 is stretched. The movable plate 23, the first limiting ring 25, and the second limiting ring 26 cooperate with the spring 24 to be subjected to the gradually increasing pulling force of the spring 24 during the period when the knob 12 moves away from the vertical plate 7, thereby preventing the threaded rod 22 from separating from the vertical plate 7.

[0030] Specific working principle:

[0031] When the device is in use, the knob 12 is turned to drive the threaded rod 22 to disengage from the U-shaped support frame 1 to release the limit on the detector 9, and the vertical plate 7 is moved left and right so that when the broken eggs identified by the detector 9 are transported to the top of the rubber pad 14, the control panel 6 can just control the pushing assembly to push the broken eggs outward. At this time, the threaded rod 22 is aligned with the thread groove 13, and the knob 12 is rotated in the opposite direction to make the threaded rod 22 threadedly connected to the U-shaped support frame 1 through the thread groove 13, and the position of the detector 9 is fixed again, and the driving motor 2 is controlled to drive the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 drives the conveyor belt 4 to rotate, thereby driving the cross bar 5 to rotate, and an empty groove is formed between the adjacent cross bars 5 and the symmetrical conveyor belt 4. The eggs are placed in the empty grooves on the upper surface of the conveyor belt 4 in turn, so that the eggs can be transported with the rotation of the conveyor belt 4, and the empty grooves can limit the eggs placed therein, thereby improving the limiting effect on the unbroken eggs and preventing the unbroken eggs from moving to the outside of the U-shaped support frame 1.

[0032] The detector 9 is started to perform grading detection on the eggs. When the detector 9 identifies a broken egg, the detector 9 sends an electrical signal to the control panel 6. When the broken egg moves to the top of the lifting plate 20, the control panel 6 controls the output ends of the first electric telescopic rod 18 and the second electric telescopic rod 19 to extend at the same time, thereby driving the lifting plate 20 and the rubber pad 14 to move upward. The rubber pad 14 moves upward and passes through the empty slot to contact the broken egg and drive the egg to move upward. After the broken egg moves to the top of the U-shaped support frame 1, the control panel 6 controls the servo motor 16 to drive the rotating plate 17 to rotate ninety degrees, thereby driving the lifting plate 20, the rubber pad 14 and the egg to rotate ninety degrees. During the rotation of the egg, it does not move relative to the rubber pad 14. Then the control panel 6 controls the output end of the first electric telescopic rod 18 to extend to drive the second T-shaped slider 21 to move upward. The second T-shaped slider 21 is relative to the lifting plate 20. The broken eggs slide upward in the second T-shaped slide groove, thereby driving the lifting plate 20 to rotate upward at one end away from the collecting trough 10. The rotation of the lifting plate 20 causes the broken eggs to tilt. When the broken eggs are affected by their own gravity and just rotate relative to the rubber pad 14, the side of the lifting plate 20 just fits the top surface of the collecting trough 10, and the broken eggs roll along the top surface of the rubber pad 14 to the inside of the collecting trough 10, thereby facilitating the collection of the broken eggs. After the broken eggs are separated from the rubber pad 14, the control panel 6 controls the output end of the first electric telescopic rod 18 to contract to restore the lifting plate 20 to a horizontal state. The control panel 6 controls the servo motor 16 to drive the lifting plate 20 to rotate ninety degrees in the opposite direction, and then the control panel 6 controls the output ends of the first electric telescopic rod 18 and the second electric telescopic rod 19 to contract simultaneously to move the lifting plate 20 downward back to its original position. During the up and down movement of the lifting plate 20, the pushing assembly never contacts the conveyor belt 4 and the cross bar 5.
