Detailed Description of the Embodiment

[0014] The technical solutions of the present application will be described in detail below in conjunction with the accompanying drawings and specific embodiments. In this specification, the dimensions of the drawings do not represent the actual size ratio. The drawings are only used to show the relative positional relationship and connection relationship between the components. Components with the same name or the same reference numeral represent similar or identical structures, and are for illustrative purposes only.

[0015] Figure 1 is a schematic diagram of the overall seed flux cutting equipment of the present application. The seed flux cutting equipment 1 includes a movable transfer component 15, and also includes a feeding station 11, a detection station 12, an orientation station 13, and a cutting station 14. The transfer component 15 cyclically and sequentially switches between the feeding station 11, the detection station 12, the orientation station 13, and the cutting station 14 to complete the operations of feeding, detecting, orienting, and cutting the seeds.

[0016] As Figure 1 in the embodiment, the transfer assembly 15 can be arranged on the rotatably arranged base 16. By rotating the base 16, the switching of the specific transfer assembly 15 between each station is realized. In the case of only four stations, the base 16 usually rotates uniformly in steps of 90 degrees. In this case, multiple sets of transfer assemblies 15 can be arranged on the base 16 to improve efficiency. In short, this purpose can be achieved by evenly distributing 4 sets of transfer assemblies 15 in the circumferential direction of the base 16. It is not excluded that the switching of the transfer assembly 15 between the seed taking station 11, the detection station 12, the orientation station 13 and the cutting station 14 is realized by other operating modes.

[0017] The transfer assembly 15 has at least one cavity for receiving a single seed. Usually, multiple cavities for receiving seeds are arranged on 15 to realize throughput operation and improve efficiency, that is, during the process other than blanking, the operations of the seeds in multiple cavities are executed in parallel to improve work efficiency. The figure shows the case of having 8 cavities 151. This means that the device can simultaneously realize the parallel operation of 8 seeds. When sectioned perpendicular to the depth direction, 151 has an oblong cross-section, so that a single seed necessarily extends along the long side direction in the cavity 151. At this time, the direction of the seed is determined, but there is a difference in the head and tail orientation.

[0018] At the seed taking station 11, the seeds from the seed taking device are sequentially placed into the corresponding cavities 151, that is, the seed taking task is completed with respect to the cavity 151. At the seed taking station 11, there is a movably arranged seeder 111, and the moving path of the seeder 111 passes through all the cavities 151 on the transfer assembly 15. By controlling the seeder 111 to stay above each cavity 151 in turn when receiving each seed, each seed is placed into the corresponding cavity 151. Usually, the seeds supplied to the seeder 111 are conveyed by a specific seed taking device, which completes the conveying of seeds by grains and provides a corresponding signal when sending out the seeds, so that the seeder 111 can be moved to the upper part of the next cavity 151 specifically. Preferably, the seed taking station 11 further includes a receiver 112. After the seeds fall from the seeder 111, they first fall into the receiver 112, rather than directly entering their respective cavities 151. After the distribution of a round of seeds is completed, the valve below the receiver 112 is opened by pneumatic or electric means, so that the seeds enter their respective cavities 151 in batches at the same time.

[0019] At the detection station 12, usually a camera array is arranged above the transfer assembly 15, and the camera array has at least one camera for obtaining the posture of the seed in the cavity 151. When there are multiple cameras, optionally, image stitching is required to stitch the pictures of multiple cameras into a single picture. The external control system can determine the head and tail orientation of the seed in the cavity 151 according to the shape of the seed in the image.

[0020] At the orientation station 13, there is an orientation assembly 131, and the orientation assembly 131 has a plurality of commutation devices 132 that independently drive the corresponding cavity 151 to change its direction. For the cavity 151 with incorrect head and tail orientation, the commutation device 132 drives the cavity 151 to rotate 180 degrees, so that the head and tail of the seeds are reversed. After this operation, all the seeds have a consistent orientation. The cavity 151 is movably arranged on the transfer assembly 15. The commutation device 132 has a rotating assembly 133 provided corresponding to each cavity 151. The rotating assembly 133 can rotate around the axis of the cavity 151, and the end of the rotating assembly 133 engages with the bottom of the cavity 151 to drive the cavity 151 to rotate and change its direction. Usually, in order to achieve the engagement, the rotating assembly 133 is arranged to be liftable. When it rises, the rotating assembly 133 engages with the cavity 151, and when it descends, it disengages, so as not to affect the flow of the picking station 11.

[0021] At the cutting station 14, there is a cutting assembly 141. The cutting assembly 141 has a first limiting member 21 that moves along a first direction corresponding to each cavity 151. When the first limiting member 21 extends into a preset position in the cavity 151, it limits the seeds in the first direction. There is a second limiting member 22 that moves along a second direction arranged in the cavity 151. When the second limiting member 22 extends into a preset position in the cavity 151, it limits the seeds in the second direction. Wherein the first direction and the second direction are not parallel to each other, and the first limiting member 21 and the second limiting member 22 limit the seeds at a suitable position in the wedge-shaped groove.

[0022] Specifically, in Figure 2 、 3 In the schematic diagram, the first limiting member 21 moves along the width direction A of the wedge-shaped groove of the cavity 151, and the second limiting member 22 moves along the depth direction B of the wedge-shaped groove. When the two come into contact and properly press the seeds, the seeds are limited at a preset position in the lower part of the cavity 151. At this time, the limitation of the seeds is actually achieved by the combined structure of the first limiting member 21, the second limiting member 22 and the wedge-shaped groove.

[0023] The seed cutting device 1 further includes a moving cutter 23. The cutter 23 can penetrate into the cavity 151 and is arranged to move to cut the seeds after the cutting limitation. Refer to Figure 2Schematic diagram, the cutting knife 23 is usually an elongated sheet arranged to move. Preferably, the cutting knife 23 is arranged parallel to the second limiting member 22, so as to cut the seeds along the same direction B. In a specific application, this realizes cutting the seeds in half to obtain the embryo head and the embryo tail. Further, the second limiting member 22 has a left limiting piece 221 and a right limiting piece 222 arranged at intervals from each other, and the cutting knife 23 is preferably arranged in the interval between the left limiting piece 221 and the right limiting piece 222. The left and right here are only used to distinguish different limiting pieces, and the left and right are defined with the cutting knife 23 as the center, but should not be understood as the left and right having a substantial limitation on the limiting pieces belonging to the second limiting member 22.

[0024] The order of moving (limiting) the seeds between the first limiting member 21 and the second limiting member 22 does not need to be precisely determined in sequence. Obviously, it is required that the action of the cutting knife 23 is after the limiting. In the case where the second limiting member 22 is arranged parallel to the cutting knife 23, the two can be independently driven. As Figure 1 shown, the second limiting member 22 is driven to move by the second driving device 223, and the cutting knife 23 is driven to move by the third driving device 231. The two moving motions can be independent. In addition, preferably, the base of the third driving device 231 can be fixed to the second limiting member 22. At this time, when the second limiting member 22 moves, the cutting knife 23 follows the second limiting member 22 to move. However, the initial position of the cutting knife 23 is not lower than the position of the second limiting member 22 (along the depth direction B), so that when the second limiting member 22 limits the seeds, the cutting knife 23 will surely not perform cutting. After that, the third driving device 231 drives the cutting knife 23 to move downward to complete the cutting or severing task.

[0025] The cavity 151 also includes two negative pressure seed taking ports 241, and the two negative pressure seed taking ports 241 are respectively opened on both sides of the cavity 151 relative to the cutting knife 23. When the seeds are cut into two segments, the two segments respectively belong to the respective regions on both sides of the cavity 151 blocked by the cutting knife 23 (merely mechanical blocking, rather than non-connectivity in space). By applying a certain negative pressure from the negative pressure seed taking ports 241, the negative pressure seed taking ports 241 can take out the cut seeds in the area on the side communicated with them. During the taking-out process, the cutting knife 23 remains inside the cavity 151 to realize the blocking of the seeds, that is, when the negative pressure is generated, it is avoided that the cut seeds in the area farther from the negative pressure seed taking port 241 on the side where the negative pressure is generated are wrongly sucked out. Because for the two negative pressure seed taking ports 241, it is necessary to specifically distinguish the cut seed segments taken out to realize the separate screening and taking out of the embryo head and the embryo tail. In short, when the seed direction is correctly specified, it is always ensured that the seed segments in the fixed side area are the embryo head, and the seed segments in the other side area are the embryo tail.
