[0002] In the main production areas in the middle and lower reaches of the Yangtze River, there is an obvious seasonal land use conflict between crab cultivation ponds and food crops such as wheat, resulting in the phenomenon of "competition for land between grain and fishery". Therefore, the crab-wheat-crab continuous cropping and cultivation mode proposed in the agricultural scientific research field realizes sustainable development of "dual use of one field and complementary planting and breeding" through ecological cycle three-dimensional development and utilization of time difference. After crabs are marketed in September-October, winter wheat is planted in a rush, and crab seedlings are put in immediately after wheat is harvested in May of the following year.

At present, manual screening is still generally used for crab seedling sorting, which has problems of low sorting efficiency and large human error. Although there are some mechanical sorting devices on the current market, their structures are complex, the cost is high, and the injury rate of crab appendages is high. Therefore, this solution proposes an intelligent sorting and temporary rearing device for crab seedlings. Summary of the Invention

Detailed Embodiment
[0038] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.
[0039] Embodiment 1:
[0040] Please combine Figure 1 - Figure 10 The crab seedling intelligent sorting and temporary rearing device of this embodiment includes:
[0041] The temporary rearing mechanism comprises a temporary rearing pond 35, and the temporary rearing pond 35 is used to culture crab seedlings in a short period of time.
[0042] The sorting mechanism includes a mounting plate 2, a conveyor belt 1 mounted on the outer wall of one side of the mounting plate 2, and a receiving plate 10 arranged on the inner side of the conveyor belt 1. A fixing plate 11 is fixed to one side of the bottom of the mounting plate 2. A plurality of fixing holes are provided on the top surface of the fixing plate 11. Before sorting crab seedlings, the fixing plate 11 is fixed to the edge of the temporary holding pool 35 by inserting a rod through the fixing holes, thereby setting the sorting mechanism above the temporary holding pool 35.
[0043] The surface of the conveyor belt 1 is provided with a plurality of sorting slots arranged along its width direction. A driving assembly for driving the conveyor belt 1 to rotate is installed on the mounting plate 2. The driving assembly includes two transmission shafts 13 rotatably connected to the outer wall of the mounting plate 2 and a motor installed on the outer wall of the other side of the mounting plate 2. One end of the output shaft of the motor is transmission-connected to one end of one of the transmission shafts 13. Two transmission wheels 15 are sleeved on the outer periphery of the transmission shaft 13. The conveyor belt 1 is sleeved on the outer periphery of the transmission wheels 15 on the two transmission shafts 13, and the two transmission wheels 15 on the same transmission shaft 13 are respectively located on both sides of the inner circle of the conveyor belt 1 deviating from the sorting slot directly below. The motor is a servo motor. After the motor is started, it drives one of the transmission shafts 13 to rotate. After the transmission shaft 13 rotates, it can drive the conveyor belt 1 to rotate accordingly. Setting the transmission wheel 15 at a position deviating from the sorting slot directly below can prevent the crab seedlings falling into the sorting slot from being crushed by the transmission wheel 15, thereby effectively reducing the damage rate of the crab seedlings.
[0044] The material receiving plate 10 is inclined, and the lower end of the material receiving plate 10 extends to the outside of the conveyor belt 1. The upper end of the material receiving plate 10 is movably connected to the mounting plate 2 through a mounting member. On both sides of the top surface of the material receiving plate 10, side plates 33 are fixed to prevent the crab seedlings on the material receiving plate 10 from falling off from the sides. The mounting member includes a support plate 34 fixed on the mounting plate 2. The bottom surface of the material receiving plate 10 abuts against the top surface of the support plate 34. A limiting groove 30 is formed in the top surface of the support plate 34 along its length direction. The mounting member further includes a limiting post 31 fixed in the limiting groove 30 and a limiting block 32 movably sleeved on the outer periphery of the limiting post 31. The top of the limiting block 32 is fixedly connected to the bottom surface of the material receiving plate 10. The arrangement of the mounting member enables the material receiving plate 10 to move along the length direction of the limiting groove 30. When sorting crab seedlings, first start the motor to rotate, and then convey the crab seedlings onto the upper surface of the conveyor belt 1. As the conveyor belt 1 rotates, the smaller-sized crab seedlings among the crab seedlings will fall from the sorting groove, then fall onto the top surface of the material receiving plate 10. Finally, place a collection bucket below the bottom of the feeding plate 10 to collect the unqualified crab seedlings. The crab seedlings with qualified size will be conveyed into the temporary cultivation pond as the conveyor belt 1 rotates, thus completing the rapid sorting of the crab seedlings.
[0045] A vibration mechanism is installed inside the conveyor belt 1 and is used to drive the material receiving plate 10 to swing left and right when the conveyor belt 1 rotates. The vibration mechanism includes two eccentric wheels 12 respectively sleeved on the outer peripheries of two transmission shafts 13 and two abutting columns 14 respectively fixed on the bottom surfaces of both sides of the material receiving plate 10. The deflection directions of the two eccentric wheels 12 are the same. At one end of each of the two abutting columns 14, a ball is installed, and the balls on the two abutting columns 14 respectively abut against the outer peripheries of the two eccentric wheels 12. After the motor drives one of the transmission shafts 13 to rotate, the conveyor belt 1 rotates accordingly, and then drives the other transmission shaft 13 to rotate synchronously. When the two transmission shafts 13 rotate, the two eccentric wheels 12 also rotate accordingly. When one of the eccentric wheels 12 pushes the abutting column 14 in contact with it to the left during rotation, the material receiving plate 10 moves leftward accordingly. Subsequently, when the other eccentric wheel 12 pushes the abutting column 14 in contact with it to the right, the material receiving plate 10 moves rightward accordingly. In this way, it reciprocates to drive the material receiving plate 10 to swing left and right back and forth, thereby accelerating the falling speed of the crab seedlings on the top surface of the material receiving plate 10.
[0046] A cleaning mechanism includes a connecting plate 26 fixed on the outer wall of the mounting plate 2 and a cleaning brush 16 installed on the connecting plate 26 through a connecting member. The cleaning brush 16 is located at the bottom of the material receiving plate 10, and the bristles on the bottom surface of the cleaning brush 16 extend into the sorting groove. When the conveyor belt 1 rotates, the bristles of the cleaning brush 16 continuously slide over the sorting groove, so as to brush off the crab seedlings stuck in the sorting groove.
[0047] Feeding mechanism, which includes a hopper 3 arranged directly above the conveyor belt 1, a limit plate 23 installed on the hopper 3 through an elastic member, a rotating shaft 17 rotatably connected to the outer wall of one side of the discharge port of the hopper 3, and a buffer plate 18 fixed to the outer circumference of the rotating shaft 17. One end of the limit plate 23 extends to the inside of the discharge port of the hopper 3, and a plurality of tooth grooves 19 are provided on the bottom surface of the limit plate 23. A linkage gear 20 meshing with the tooth grooves 19 is sleeved on the outer circumference of the rotating shaft 17. The buffer plate 18 is inclined, and the bottom of the buffer plate 18 overlaps on the surface of the conveyor belt 1. The elastic member includes a connecting block 22 fixed to the top surface of the outer end of the limit plate 23 located outside the hopper 3 and a plurality of connecting springs 21 fixed to the connecting block 22. The other end of the connecting spring 21 is fixedly connected to the outer wall of the hopper 3. Under the action of the elastic force of the connecting spring 21, the bottom of the buffer plate 18 always abuts against the top surface of the conveyor belt 1. When the bottom of the buffer plate 18 slides into the sorting groove, the buffer plate 18 will rotate downward under the action of the spring, and the rotating shaft 17 will rotate synchronously with the buffer plate 18, thereby driving the linkage gear 20 to rotate clockwise. The linkage gear 20 then drives the limit plate 23 to move inward towards the hopper 3, thereby reducing the size of the falling space of the crab seedlings in the hopper 3 and reducing the falling speed of the crab seedlings. As the conveyor belt 1 continues to rotate, the buffer plate 18 will rotate upward under the drive of the conveyor belt 1. At this time, it will drive the limit plate 23 to move inward towards the hopper 3, thereby accelerating the falling speed of the crab seedlings. Then the buffer plate 18 will slide into the next sorting groove under the rotation of the conveyor belt 1, and further reduce the falling speed of the crab seedlings. This process repeats, and thus the purpose of intelligently regulating the falling speed of the shrimp seedlings can be achieved, avoiding the problem of untimely sorting caused by the too fast falling speed of the crab seedlings.
[0048] A plurality of groups of soft brushes are fixed to the inner end of the limit plate 23 located inside the hopper 3. The soft brushes can limit the falling speed of the crab seedlings while avoiding pinching the crab seedlings.
[0049] Embodiment 2:
[0050] Combined with Figure 3 and Figure 7 - Figure 10, on the basis of Embodiment 1, the further improvement of this embodiment lies in that: a transmission assembly is installed between the cleaning brush 16 and the bottom of the material receiving plate 10 to drive the cleaning brush 16 to move along the length direction of the sorting tank when the material receiving plate 10 swings left and right. An installation hole 25 is opened on the bottom surface of the material receiving plate 10, and an installation groove 29 arranged along the width direction of the conveyor belt 1 is opened on the top surface of the connecting plate 26. The connecting piece includes a sleeve rod 28 fixed in the installation groove 29, a connecting column 24 movably sleeved on the outer periphery of the sleeve rod 28, and an abutting block 27 fixed in the installation hole 25. Two reset springs are sleeved on the outer periphery of the sleeve rod 28, respectively located on both sides of the connecting column 24. One end of the reset spring is fixedly connected to the connecting column 24, and the other end of the reset spring is fixedly connected to the inner wall of the installation groove 29. The abutting block 27 is in the structure of a right-angled triangular prism. The top of the connecting column 24 extends into the installation hole 25, and a slope that fits the hypotenuse of the abutting block 27 is opened on one side of the end of the connecting column 24 located in the installation hole 25. During the left and right swinging process of the material receiving plate 10, the abutting block 27 will be driven to move synchronously. When the abutting block 27 presses the connecting column 24 during the moving process, the connecting column 24 will be forced to move forward along the length direction of the sleeve rod 28. After the connecting column 24 moves, one of the reset springs is stretched and the other reset spring is compressed. When the material receiving plate 10 moves back, under the action of the two reset springs, the connecting column 24 will automatically move backward. In this way, during the left and right back-and-forth process of the material receiving plate 10, the connecting column 24 can be driven to move back and forth, and then drive the cleaning brush 16 to move back and forth along the length direction of the sorting tank, so that the crab seedlings stuck in the sorting tank can be cleaned out more thoroughly.
[0051] Embodiment 3:
[0052] Combined with Figure 1 - Figure 3 , on the basis of Embodiment 1, the further improvement of this embodiment lies in that: two baffle plates 5 are fixed on the mounting plate 2, and the two baffle plates 5 are respectively located at positions on both sides of the top surface of the conveyor belt 1 deviating from directly above the sorting tank, and the bottom surface of the baffle plate 5 abuts against the top surface of the conveyor belt 1. A quantity control brush 4 is installed between the two baffle plates 5. A gap for crab seedlings to pass through is provided between the bottom of the quantity control brush 4 and the top surface of the conveyor belt 1. The hopper 3 is fixed between the two baffle plates 5. The baffle plates 5 can effectively prevent the crab seedlings on the surface of the conveyor belt 1 from falling from both sides of the conveyor belt 1, and the quantity control brush 4 can brush away the crab seedlings piled up on the surface of the conveyor belt 1, avoiding small-sized crab seedlings from being sandwiched inside large-sized crab seedlings and unable to be screened out.
[0053] Both ends of the metering brush 4 are rotatably connected to two baffles 5 through connecting shafts 7, and one end of one of the connecting shafts 7 extends to the outside of the baffle 5. A fixing sleeve 6 fixedly connected to the baffle 5 is sleeved on the outer periphery of the connecting shaft 7. A locking bolt 9 abutted against the connecting shaft 7 is threadedly connected to the outer periphery of the fixing sleeve 6. A runner 8 is fixed at one end of the connecting shaft 7 located outside the fixing sleeve 6. After the locking bolt 9 is tightened, the connecting shaft 7 can be locked by using the static friction force between it and the connecting shaft 7, so as to prevent the metering brush 4 from rotating. When cleaning the metering brush 4, the locking bolt 9 can be loosened, and then the runner 8 can be rotated to turn over the metering brush 4, so as to achieve the purpose of facilitating the cleaning of the metering brush 4.
[0054] The above-mentioned embodiments are only the preferred embodiments of the present invention, and the scope of protection of the present invention cannot be limited thereby. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
