This method is simple, convenient, and reduces costs.

[0036] Example 2

[0037] Reference Figs. 1-6This is the second embodiment of the present invention. Unlike the previous embodiment, the frame 101 includes a first frame head 101a, a second frame head 101b, and a hook 101c.

The limiting shaft 101c-24 is located on the hook head 101c-22. The rotating hole 101c-21 is located on the side of the hook body 101c-2 that is biased towards the hook tail 101c-23. The position of the rotating hole 101c-21 causes the center of gravity of the hook 101c to shift. When the hook 101c is not holding the screen 103, the hook head 101c-22 faces downward and the hook tail 101c-23 faces upward.

[0040] Furthermore, the column 102a includes a groove 102a-1, which is disposed on the column 102a;

[0041] The connecting frame 102b includes a sleeve shaft 102b-1 and a support plate 102b-2. The sleeve shaft 102b-1 is axially connected to the column 102a, and the support plate 102b-2 is disposed on the sleeve shaft 102b-1.

The first gear 102c-1 and the second gear 102c-2 are meshed and connected. The threaded column 102c-3 is fixedly disposed on the second gear 102c-2, and the support component 102c-4 is threadedly connected to the threaded column 102c-3.

[0042] Furthermore, the frame 103a includes an algae-unloading side 103a-1, which is disposed on the frame 103a; the connecting rod 103b includes a protrusion 103b-1, which is disposed on the connecting rod 103b; the connecting column 103c includes a connecting shaft 103c-1, which is disposed on the connecting column 103c; the connecting rod 103b is disposed on one side of the frame 103a, but not in the middle of one side of the frame 103a. When the connecting rod 103b interferes with the hook head 101c-22, the connecting rod 103b is on the drooping side of the hook head 101c-22, which makes it convenient for the connecting rod 103b to lift the hook head 101c-22.

[0043] In use, one end of the first gear 102c-1 is connected to the motor, and the first gear 102c-1 is the driving transmission gear. The first gear 102c-1 meshes with the second gear 102c-2. The threaded post 102c-3 is fixedly mounted on the second gear 102c-2 and serves as the transmission post. The support member 102c-4 is threadedly connected to the threaded post 102c-3, and the support member 102c-4 moves within the groove 102a-1 of the post 102a. The sleeve shaft 102b-1 is mounted on the support member 102c-2. On the -4, the sleeve shaft 102b-1 moves together with the support member 102c-4; a support plate 102b-2 is provided on one side of the sleeve shaft 102b-1, and the support plate 102b-2 is fixedly connected to the sleeve shaft 102b-1, and the support plate 102b-2 also moves together with the support member 102c-4; the connecting shaft 103c-1 is axially connected to the connecting through hole 101b-2. When the protrusion 103b-1 is located on the inner curved side of the hook tail 101c-23, the algae discharge side 103a-1 of the screen 103 tilts upward, and the microalgae fall from the algae outlet into the screen 103. To ensure that microalgae can better reside within the screen 103, the limiting shaft 101c-24 is mounted on the hook head 101c-22. The hook head 101c-22 of the hook 101c is heavier than the hook tail 101c-23. Simultaneously, the rotating hole 101c-21 is located on the side of the hook body 101c-2 biased towards the hook tail 101c-23. When the support member 102c-4 continues to move upwards, and the support plate 102b-2 supports the screen 103, the hook 101c is not under force, with the hook head 101c-22 pointing downwards and the hook tail 101c-23 pointing upwards; when the support plate 102b-2 supports the screen 103, the hook 101c is not under force, with the hook head 101c-22 pointing downwards and the hook tail 101c-23 pointing upwards. When the support 102c-4 descends and then rises again, the screen 103 is lifted upward by the support plate 102b-2. The connecting rod 103b is not located in the middle position on one side of the frame 103a. When the connecting rod 103b interferes with the hook 101c-22, the connecting rod 103b is pushed upward from the drooping side of the hook 101c-22 until the protrusion 103b-1 falls back into the inner bend of the hook tail 101c-23. At this point, the linkage mechanism completes all the movements. All reciprocating movements are completed through mechanical structure, saving equipment and labor costs.

[0044] Example 3

[0045] Reference Figs. 1-7 This is the third embodiment of the present invention. This embodiment further provides a continuous harvesting device, including a harvesting unit 200 and a linkage unit 100 disposed on one side of the harvesting unit 200. The harvesting unit 200 includes an algae discharge pump 201, a recovery tank 202 and a collection channel 203. The algae discharge pump 201 is disposed on one side of the recovery tank 202 and the collection channel 203 is disposed on the other side of the recovery tank 202.

[0046] Preferably, the algae outlet pump 201 includes a water pump 201a and an algae outlet 201b. The algae outlet 201b is located on one side of the water pump 201a. The algae outlet 201b is configured with multiple channels according to the particle size of the algae solution. Different sizes of microalgae can be screened by switching through valves.

[0047] In summary, pump 201a extracts the microalgae solution, which flows out through valves from different algae outlets 201b. One end of the first gear 102c-1 is connected to the motor, and the first gear 102c-1 is the driving transmission gear. The first gear 102c-1 meshes with the second gear 102c-2. The threaded column 102c-3 is fixedly mounted on the second gear 102c-2 and serves as the transmission column. The support member 102c-4 is threadedly connected to the threaded column 102c-3, and the support member 102c-4 moves within the groove 102a-1 of the column body 102a. The sleeve shaft 102b-1 is mounted on the support. On the support member 102c-4, the sleeve shaft 102b-1 moves together with the support member 102c-4; a support plate 102b-2 is provided on one side of the sleeve shaft 102b-1, and the support plate 102b-2 is fixedly connected to the sleeve shaft 102b-1, and the support plate 102b-2 also moves together with the support member 102c-4; the connecting shaft 103c-1 is axially connected to the connecting through hole 101b-2. When the protrusion 103b-1 is located on the inner curved side of the hook tail 101c-23, the algae discharge side 103a-1 of the screen 103 tilts upward, and when the microalgae fall from the algae outlet into the screen 103, it ensures that the microalgae can be better contained within the screen 103, limiting the shaft. 101c-24 is mounted on the hook head 101c-22. The hook head 101c-22 of the hook 101c is heavier than the hook tail 101c-23. Meanwhile, the rotating hole 101c-21 is located on the side of the hook body 101c-2 biased towards the hook tail 101c-23. When the support member 102c-4 continues to move upward, and the support plate 102b-2 supports the screen 103, the hook 101c is not under force, the hook head 101c-22 faces downward, and the hook tail 101c-23 faces upward. When the support member 102c-4 descends and then rises again, the screen 103 is lifted upward by the support plate 102b-2, and the connecting rod 103b is not located on the screen. At the middle position on one side of the frame 103a, when the connecting rod 103b interferes with the hook head 101c-22, the connecting rod 103b is pushed upward from the drooping side of the hook head 101c-22 until the protrusion 103b-1 falls back into the inner bend of the hook tail 101c-23. The screen 103 leaves water from the microalgae through the screen holes and flows into the recycling tank 202. When the algae unloading side 103a-1 of the screen 103 is tilted downward, the height of the algae unloading side 103a-1 is low, and the microalgae fall from the algae unloading side 103a-1 into the collection channel 203. The microalgae continuous harvesting device realizes an uninterrupted harvesting process, which greatly improves production efficiency and output.
