The swing rod 52 is swingably mounted on the frame 7 via a pin, the second wheel 51 is connected to the swing rod 52 via a pin, so that the second wheel 51 can rotate on the swing rod 52, and the second wheel 51 abuts against the cam of the second cam device 54, the ejector seat 53 is fixedly connected to the swing rod 52 via bolts, and the ejector 4 is fixedly embedded in the ejector seat 53.

[0028] In addition, the first cam device 31 and the second cam device 54 can be arranged on the same rotating shaft, and the rotating shaft is driven by a power device, so that the movement of the rotating shaft can correspondingly rotate the first cam device 31 and the second cam device 54 to realize the linkage of the pressing block lifting mechanism 3 and the ejector lifting mechanism 5.

[0029] The chain conveyor 6 comprises a driving wheel, a driven wheel and a plurality of sprocket wheels 61. The driving wheel and the driven wheel are both mounted on the frame 7 through bearings, the driving wheel can be connected with a motor, and a plurality of sprocket wheels 61 are connected in sequence to form a chain, and the chain can bypass the driving wheel and the driven wheel. The sprocket wheel 61 is preferably a silica gel sprocket wheel, and an accommodating space 611 can be formed between adjacent sprocket wheels 61, and the accommodating space 611 can accommodate lotus seeds, and at this time, the lotus seeds can be supported by adjacent sprocket wheels 61.

[0031] The novel lotus seed steering device further comprises a detection device 8 , which can be a color code detector or a CCD detector, etc. The detection device 8 is fixedly mounted on the frame 7 through a connecting frame, and the detection device 8 can detect the orientation of the lotus seeds on the sprocket 61 .

[0032] When the novel lotus seed steering device is in use, each accommodating space 611 on the chain conveyor device 6 can be respectively placed with lotus seeds, and as the chain on the chain conveyor device 6 moves, each accommodating space 611 can move accordingly to realize the transportation of lotus seeds.

[0033] When the lotus seeds on a certain accommodating space 611 move to the top of the ejector pin 4, that is, also located below the pressing block 1, the power device can drive the rotating shaft to rotate, the first cam device 31 and the second cam device 54 move, and the first stop wheel 32 and the second stop wheel 51 can move accordingly.

[0034] On the one hand, the movement of the second wheel 51 can make the swing rod 52 swing, and the ejector seat 53 moves up accordingly, so that the ejector 4 moves up, and the ejector 4 can eject the lotus seeds above it from the accommodating space 611. At the same time, on the other hand, the movement of the first wheel 32 can make the first connecting rod 33 swing, and the swing of the first connecting rod 33 can drive the rotating shaft 34 to rotate, so that the second connecting rod 35 connected to the rotating shaft 34 can swing, so that the pressing block 1 is pressed on the lotus seeds below it.

[0038] The moving frequency of the sprocket wheel 61 of the chain conveyor device 6 in the novel lotus seed steering device can adapt to the action frequency of the first cam device 31 and the second cam device 54, that is, the moving speed of the sprocket wheel 61 will be slightly greater than the required time for the lotus seed reversal, so that after the lotus seeds in a receiving space 611 are reversed each time, with the action of the chain conveyor device 6, the lotus seeds in the receiving space 611 that have completed the reversal can be transported away, and the next receiving space 611 can move to the top of the current ejector pin 4 and the bottom of the pressing block 1 to perform the next reversal. The above operation is repeated, so that the lotus seeds transported by the chain conveyor device 6 can eventually have the same direction.

[0039] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
