When the floating plate stack enters the unstacking machine 800 and is located on the unstacking conveyor belt, the unstacking clamping cylinders 81 clamp the floating plate stack except the bottom floating plate through the unstacking clamping plates, the unstacking conveyor belt rotates and pushes the bottom floating plate out to the first elevator 100 through the unstacking belt push plates 82. Specifically, the air transfer machine 500 transfers the floating plate stack to the second transfer trolley 93, and the floating plate stack on the second transfer trolley 93 is conveyed to the unstacking conveyor belt of the unstacking machine 800. The floating plate stack on the second transfer trolley 93 can enter the unstacking machine 800 by manual pushing and pulling or other ways. The unstacking clamping cylinders 81 push the unstacking clamping plates to clamp the floating plate stack except the bottom floating plate, the unstacking conveyor belt rotates and pushes the bottom floating plate out to the first elevator 100 through the unstacking belt push plates 82, then the unstacking conveyor belt reverses to the original position, the unstacking clamping cylinders 81 release the unstacking clamping plates, and the floating plate stack falls onto the unstacking conveyor belt again, and so on to unstack the floating plates. The unstacking conveyor belt can be driven by a motor, and the forward and reverse rotation of the unstacking conveyor belt can be controlled by the motor. The unstacking belt push plates 82 push the bottom floating plate out to the bracket 3 of the first elevator 100, and the first elevator 100 transfers the floating plate to the first conveying platform 101 after one rotation.

A second rack is arranged on the transverse moving frame 51, and a second gear and a second motor are arranged on the air transfer machine 500, the second motor drives the second gear to rotate, so that the air transfer machine 500 moves along the transverse moving frame 51. The air transfer machine 500 further includes a gear and rack assembly 55, which includes a third rack and a third gear, the third gear is fixedly arranged relative to the air transfer machine 500, and the third rack is connected with the transfer bracket 53 at one side. When the third gear is driven, the third rack moves up and down, so that the transfer bracket 53 moves up and down. The rotation of the third gear can be realized by arranging a third motor.

[0056] The aerial transfer machine 500 further comprises a support guide rail for guiding the transfer supports 53, and the lower ends of the transfer supports 53 are further connected to transfer supporting feet. For a certain pile of floating plates, the third gear drives the third rack to move downward, so that the lower ends of the transfer supports 53 move to the lower side of the pile of floating plates, the transfer clamping cylinders 54 are retracted, so that the two transfer supports 53 are close to each other to clamp the pile of floating plates, the pile of floating plates is supported on the transfer supporting feet at the same time, the third gear drives the third rack to move upward, the transfer supports 53 drive the pile of floating plates to move upward, and then the aerial transfer machine 500 moves along the transverse moving frame 51, the transverse moving frame 51 moves along the rail frame 52, and the pile of floating plates is transferred to different positions.

[0057] In combination Figures 5-10 As shown, the second elevator 700 and the first elevator 100 are consistent in structure, and the only difference is that the transfer directions of the floating plates 4 are different. Specifically, the first elevator 100 lifts and conveys the floating plates 4 to the first conveying platform 101, and the floating plates 4 are conveyed to the second elevator 700 through the first conveying platform 101, and the second elevator 700 lowers and conveys the floating plates to the second conveying platform 102.

[0058] In this embodiment, the structure of the first elevator 100 is described. The first elevator 100 comprises a frame 1, four conveying guide assemblies 2 and four brackets 3, and the number of the conveying guide assemblies 2 corresponds to the number of the brackets 3. In other embodiments, other numbers of the conveying guide assemblies 2 and the brackets 3 can be set according to the transfer efficiency needs.

[0059] The frame 1 is provided with a ring-shaped rail 11, and the rail 11 has a plurality of different side walls. The conveying guide assembly 2 comprises a conveying block 21 moving along the rail 11, a guide assembly located at the rear side of the conveying block 21, and a rotating shaft 20 penetrating the conveying block 21. The bracket 3 is located at the front side of the conveying block 21, one end of the rotating shaft 20 is fixedly connected to the guide assembly, and the other end is fixedly connected to the bracket 3. The guide assembly comprises a horizontal guide wheel and a vertical guide wheel, and the horizontal guide wheel and the vertical guide wheel move along the different side walls of the rail 11, so that when the conveying guide assembly 2 drives the bracket 3 to move, the bracket 3 remains in a horizontal state relative to the frame 1.

[0060] In the scheme, four conveying guide assemblies 2 and carriers 3 are arranged, the driving assembly drives the conveying guide assemblies 2 to operate and drives the carriers 3 to move, and each carrier 3 can support a floating plate. The driving assembly can transfer four floating plates in each operation cycle, greatly improving the conveying efficiency of the elevator. In addition, the guide assemblies and the carriers 3 are arranged on the front and rear sides of the conveying block 21 respectively, and are connected through the rotating shaft 20 penetrating the conveying block 21, so that the balance of the rotating shaft 20 is better. Since the floating plate is a foam plate formed of foam material, the weight of a single floating plate is usually about 200g, which is relatively light. In the scheme, the guide assemblies and the carriers 3 are arranged on the front and rear sides of the conveying block 21, so that the conveying guide assemblies 2 and the carriers 3 can operate more stably, effectively avoiding the floating plate from falling during conveying.

[0061] In Figure 5 and Figure 6 , the front side of the conveying block 21 is the side close to the carrier 3 and the floating plate, and the rear side is the side opposite to the front side.

[0062] In combination with Figure 8 and Figure 9 , regarding the track 11 and the guide assembly, the guide assembly includes a horizontal frame 23 and a vertical frame 24 arranged in cross vertical direction, and one end of the rotating shaft 20 is connected to the intersection of the horizontal frame 23 and the vertical frame 24. The carrier 3 always keeps the same direction with the horizontal frame 23 and keeps vertical arrangement with the vertical frame 24. The track 11 includes two oppositely arranged vertical segments and two oppositely arranged arc-shaped segments, the vertical segment has a first track side wall 13, and the vertical guide wheel moves along the first track side wall 13 when the conveying guide assembly 2 moves vertically. The arc-shaped segment is provided with a second track, and the horizontal guide wheel moves along the second track side wall 14 of the second track when the conveying guide assembly 2 moves on the arc-shaped segment.

[0063] In detail, when the conveying guide assembly 2 moves vertically, the vertical guide wheel moves along the first track side wall 13, and under the interaction of the first track side wall 13 and the vertical guide wheel, the vertical frame 24 always keeps vertical state, and the horizontal frame 23 always keeps horizontal state, so that the carrier 3 keeps horizontal. See Figure 5During the transition of the conveying guide assembly 2 from the vertical section of track 11 to the arc section, the horizontal guide wheel begins to contact the second track sidewall 14. The second track sidewall 14 is arc-shaped, matching the trajectory of the horizontal guide wheel. Under the action of the second track sidewall 14 and the horizontal guide wheel, the vertical frame 24 remains vertical and the horizontal frame 23 remains horizontal at the arc section, thus keeping the bracket 3 horizontal. To avoid interference, when the vertical frame 24 and the vertical guide wheel pass through the arc section of track 11, the space in track 11 at the point where the vertical frame 24 and the vertical guide wheel pass needs to be increased to allow them to pass smoothly. Similarly, when the horizontal frame 23 and the horizontal guide wheel pass through the vertical section of track 11, the space in track 11 at the point where the horizontal frame 23 and the horizontal guide wheel pass needs to be increased to allow them to pass smoothly.

[0064] Combination Figure 7 and Figure 8 As shown, an even number of moving wheels 22 are connected to the conveying block 21, preferably eight. More preferably, two moving wheels 22 can be used; even more preferably, four moving wheels 22 can be used. In this embodiment, eight moving wheels 22 are used for illustration. Specifically, third guide rails 15 are respectively provided on both sides of the track 11; when the conveying block 21 moves along the track 11, every two moving wheels 22 move on both sides of the third guide rail 15. With eight moving wheels 22, every two moving wheels 22 are located at a right-angle corner of the conveying block 21, so that the moving wheels 22 limit and guide the conveying block 21 in four directions, so that the conveying block 21 moves smoothly, reduces the amount of swaying of the conveying block 21, and thus the floating plate is conveyed smoothly.

[0065] See details Figure 9 As shown, the conveyor block 21 moves along the third guide rail 15 under the guidance of the third guide rail 15. To ensure that the relative position of the third guide rail 15 and the first track sidewall 13 is satisfied when the conveyor block 21 moves along the vertical section of the track 11, the vertical guide wheel can move along the first track sidewall 13. Similarly, when the conveyor block 21 moves along the arc section of the track 11, the relative position of the third guide rail 15 and the second track sidewall 14 is satisfied, allowing the horizontal guide wheel to move along the second track sidewall 14.

[0066] More specifically, the first elevator 100 further comprises a driving assembly, which comprises two sprockets and a chain 12, the sprockets are respectively located at the arc-shaped sections of the tracks 11, and the chain 12 is arranged in a closed loop around the sprockets. The chain 12 is connected with the conveying block 21. Moreover, the third guide rail 15 is arranged in the same direction as the chain 12. In one case, one of the two sprockets is a driving sprocket, and the other is a driven sprocket. A motor is used to drive the driving sprocket to rotate, so that the chain 12 rotates. The chain 12 drives the conveying block 21 to move, and the conveying block 21 appears a 180-degree turning once every time passing through an arc-shaped section of the track 11. The rotating shaft 20 is arranged relative to the conveying block 21, and the two ends of the rotating shaft 20 are fixedly connected with the guide assembly and the bracket 3. Under the joint action of the guide assembly and the different side walls of the track 11, the bracket 3 can be kept horizontal.

[0067] Generally, in order to ventilate during the breeding and seedling raising process, a through hole is formed on the floating plate. In this scheme, the bracket 3 comprises a connecting frame 33 and a plurality of support frames 31 connected with the connecting frame 33, and the support frames 31 are connected with positioning columns 32. The positions of the positioning columns 32 correspond to the positions of the through holes on the floating plate. When the floating plate is supported on the bracket 3, the positioning columns 32 are located in the through holes, further avoiding the floating plate from falling. In addition, the rotating shaft 20 is connected with the connecting frame 33 at the middle position, further maintaining the stability of the floating plate.

[0068] As a preferred embodiment, in combination with the drawings shown in Figure 8 and Figure 9 , the horizontal guide wheels comprise a first horizontal guide wheel 231 and a second horizontal guide wheel 232, which are respectively connected at the two ends of the horizontal frame 23; the vertical guide wheels comprise a first vertical guide wheel 241 and a second vertical guide wheel 242, which are respectively connected at the two ends of the vertical frame 24.
