The same grading egg bin 70, the grading egg bin 70 and the blocking chute 62 are in a sequential corresponding relationship. A shock-absorbing mechanism 71 is provided at the bottom of the grading egg bin 70, and a bin door 72 is provided on the front side of the grading egg bin 70. The eggs are used to slide from the first feeding chute 30 into the feeding port 1101, and then pass through the second feeding chute 40, and then hit the anti-collision wall 50 and fall onto the grading chute 60. The size of the eggs is graded by the grading chute 60, and they fall at the corresponding grade size position, and their falling position is limited by the blocking chute 62, so that they fall correctly into the corresponding grading egg bin 70. At the same time, the shock-absorbing mechanism 71 in the grading egg bin 70 reduces the shock to prevent the eggs from being damaged, thereby completing the grading and screening of the eggs. The device does not require electricity to use a high-power transmission structure, is simple to operate, and is similar in size to a suitcase, with the advantage of high portability.

[0027] In this embodiment, an embedding groove 1102 is opened on the left side of the top of the top plate 11, and the embedding groove 1102 is connected to the feeding port 1101. A hinge part is provided at the intersection, and one end of the first feeding chute 30 is hinged to the hinge part. When the first feeding chute 30 is kept horizontal with the top plate 11, the first feeding chute 30 is embedded in the embedding groove 1102.

[0028] like Figure 4 As shown, the top of the top plate 11 is located on the left side of the embedding groove 1102, and a first sliding groove 1103, a second sliding groove 1104 and a third sliding groove 1105 that are interconnected are provided from top to bottom. The third sliding groove 1105 is connected to the embedding groove 1102, and a circle of flange 1106 is provided on the inner wall of the third sliding groove 1105 near the left side. A diagonal support plate 12 is provided between the bottom of the top plate 11 and the inner wall of the box body 10.

[0029] Furthermore, the slide pop-up mechanism 32 includes a pop-up switch 3201 and a pneumatic spring telescopic rod 3202. The pop-up switch 3201 includes a latch 32011.

The connecting column 32013 and the toggle block 32014 are movably arranged in the second sliding groove 1104 and the first sliding groove 1103 respectively. A resisting spring 32015 is provided between the flange 1106 and the connecting column 32013. The left end of the first feeding slide 30 has a downward The inclined notch has an inclined socket 31. When the first feeding chute 30 is embedded in the embedding groove 1102, the oblique plug 32012 is embedded in the oblique socket 31. The bottom of the pneumatic spring telescopic rod 3202 is hinged to the top of the diagonal support plate 12. The end of the output shaft of the pneumatic spring telescopic rod 3202 passes through the top plate 11 and is hinged to the bottom of the first feeding chute 30. The first sliding groove 1103 can be supported by the pneumatic spring telescopic rod 3202 to form an inclined surface with the top plate 11, and eggs are fed into this inclined surface, which makes the operation more convenient. When not in use, the pop-up switch 3201 can be engaged with the oblique plug 32012 to make the first feeding chute 30 fit into the embedding groove 1102 for easy storage and transportation.

[0030] In this embodiment, the grading slide 60 includes two grading rods 61 disposed inside the box body 10 . The grading rods 61 are inclined downward from left to right, and the distance between the two grading rods 61 increases from left to right.

[0031] As a preferred embodiment, the blocking chute 62 is installed between the front and rear sides of the bottom of the grading chute 60, and its direction is inclined from top to bottom to the left, and its extension line is located at the center of the grading egg bin 70. During the falling process, the eggs will move parabolically to the right. In order to prevent the eggs from falling into grading egg bins 70 of other sizes, by setting the blocking chute 62 above the right side wall of the grading egg bin 70, the movement trajectory of the eggs can be simplified and guided to the grading egg bin 70 corresponding to the falling.

[0032] As a preferred embodiment, a plurality of sponge strips are linearly and equally divided on the surface of the first feeding chute 30, the second feeding chute 40 and the blocking chute 62. There are two sponge strips on the left and right. One is to protect the safety of the eggs during the rolling process to avoid collision and damage, and the other is to slow down the rolling speed of the eggs to avoid collision and damage at various transition points due to excessive speed. Side barriers are provided on both sides of the length direction of the first feeding chute 30 and the blocking chute 62. The side barriers ensure that the eggs move along a predetermined trajectory to better protect the eggs.

[0033] like Figure 5 As shown, the shock absorbing mechanism 71 includes a buffer plate 7101 and a shock absorbing spring 7103. The front end of the buffer plate 7101 is hinged to the bottom of the grading egg bin 70. A shock absorbing spring 7103 is provided between the rear side of the bottom of the buffer plate 7101 and the bottom wall of the grading egg bin 70. The top of the buffer plate 7101 is provided with evenly distributed sponge blocks 7102. When an egg falls onto the buffer plate 7101, it is buffered by the sponge blocks 7102 and the shock absorbing spring 7103 in turn, thereby ensuring that the egg remains intact under a certain drop.

[0034] In this embodiment, a door curtain 73 is provided on the outer top of the bin door 72 to prevent eggs from rushing out of the egg grading bin 70 quickly and being broken.

[0035] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
