The number of conveying guide assemblies 2 corresponds to the number of brackets 3. In other embodiments, other numbers of conveying guide assemblies 2 and brackets 3 can be provided according to the transfer efficiency needs.

[0039] The frame 1 is provided with a track 11 in the form of a ring, and the track 11 has a plurality of different side walls. The conveying guide assembly 2 comprises a conveying block 21 moving along the track 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, and 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 track 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.

[0040] In this scheme, four conveying guide assemblies 2 and brackets 3 are provided, and the driving assembly drives the conveying guide assemblies 2 to operate and drives the brackets 3 to move. Each bracket 3 can support a floating plate. The driving assembly can transfer four floating plates in one cycle, greatly improving the conveying efficiency of the circulating transfer device. In addition, the guide assembly and the bracket 3 are respectively arranged on the front and rear sides of the conveying block 21 and are connected by the rotating shaft 20 penetrating the conveying block 21, which can make the balance of the rotating shaft 20 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 this scheme, the guide assembly and the bracket 3 are arranged on the front and rear sides of the conveying block 21, so that the conveying guide assembly 2 and the bracket 3 can operate more stably, effectively avoiding the floating plate from falling during the conveying process.

[0041] In this scheme, four conveying guide assemblies 2 and brackets 3 are provided, and the driving assembly drives the conveying guide assemblies 2 to operate and drives the brackets 3 to move. Each bracket 3 can support a floating plate. The driving assembly can transfer four floating plates in one cycle, greatly improving the conveying efficiency of the circulating transfer device. In addition, the guide assembly and the bracket 3 are respectively arranged on the front and rear sides of the conveying block 21 and are connected by the rotating shaft 20 penetrating the conveying block 21, which can make the balance of the rotating shaft 20 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 this scheme, the guide assembly and the bracket 3 are arranged on the front and rear sides of the conveying block 21, so that the conveying guide assembly 2 and the bracket 3 can operate more stably, effectively avoiding the floating plate from falling during the conveying process. Figure 1 and Figure 2 As shown in the view, for the conveying block 21, the side close to the bracket 3 and the floating plate is the "front side", and the other side opposite to the "front side" is the "rear side".

[0042] As shown in Figure 5 and Figure 6 As shown, regarding the track 11 and the guide assembly, the guide assembly comprises a horizontal frame 23 and a vertical frame 24 arranged in a cross vertical manner, and one end of the rotating shaft 20 is connected to the intersection of the horizontal frame 23 and the vertical frame 24. The bracket 3 is always arranged in the same direction with the horizontal frame 23 and in a vertical manner with the vertical frame 24. The track 11 comprises two oppositely arranged vertical segments and two oppositely arranged arc segments, and the vertical segment has a first track side wall 13. When the conveying guide assembly 2 moves vertically, the vertical guide wheel moves along the first track side wall 13. The arc segment is provided with a second track, and when the conveying guide assembly 2 moves on the arc segment, the horizontal guide wheel moves along the second track side wall 14 of the second track.

[0043] In detail, when the conveying guide assembly 2 moves vertically, the vertical guide wheels move along the first track side wall 13, and under the interaction of the first track side wall 13 and the vertical guide wheels, the vertical frame 24 is always kept in a vertical state, and the horizontal frame 23 is always kept in a horizontal state, so that the carrier 3 is kept horizontal. See Figure 5 In the transition process of the conveying guide assembly 2 from the vertical section of the track 11 to the arc section, the horizontal guide wheels begin to contact the second track side wall 14, which is in an arc shape matching the track of the horizontal guide wheels, and under the action of the second track side wall 14 and the horizontal guide wheels, at the arc section, the vertical frame 24 is still always kept in a vertical state, and the horizontal frame 23 is still always kept in a horizontal state, so that the carrier 3 is still kept horizontal. In order to avoid interference, the space of the track 11 where the vertical frame 24 and the vertical guide wheels pass through needs to be enlarged when the vertical frame 24 and the vertical guide wheels pass through the arc section of the track 11, so that the vertical frame 24 and the vertical guide wheels can pass through smoothly; similarly, the space of the track 11 where the horizontal frame 23 and the horizontal guide wheels pass through needs to be enlarged when the horizontal frame 23 and the horizontal guide wheels pass through the vertical section of the track 11, so that the horizontal frame 23 and the horizontal guide wheels can pass through smoothly.

[0044] As shown in Figure 3 and Figure 4 shown, an even number of moving wheels 22 are connected to the conveying block 21, and preferably the number of moving wheels 22 is 8. More preferably, the moving wheels 22 can be provided in 2; more preferably, the moving wheels 22 can also be provided in 4. In the present embodiment, the moving wheels 22 are described as being provided in 8. Specifically, the two sides of the track 11 are also provided with third guide rails 15; when the conveying block 21 moves along the track 11, every two moving wheels 22 are located on the two sides of the third guide rail 15. The moving wheels 22 are provided in 8, and every two moving wheels 22 are located at a right-angled 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 stably and reduces the amount of shaking of the conveying block 21, so that the floating plate is stably conveyed.

[0045] As shown in Figure 5 specifically, the conveying block 21 moves along the third guide rail 15 under the guidance of the third guide rail 15, and in order to meet the need for the relative position of the third guide rail 15 and the first track side wall 13 when the conveying block 21 moves along the vertical section of the track 11, so that the vertical guide wheels can move along the first track side wall 13. Similarly, in order to meet the need for the relative position of the third guide rail 15 and the second track side wall 14 when the conveying block 21 moves along the arc section of the track 11, so that the horizontal guide wheels can move along the second track side wall 14.

[0046] More specifically, the circulating transfer device further includes a drive assembly, which comprises two sprockets and a chain 12. The sprockets are located at the arc-shaped sections of the track 11, and the chain 12 is arranged to enclose the sprockets. The chain 12 is connected to the conveyor block 21. Moreover, the direction of the third guide rail 15 is consistent with the direction of the chain 12. In one case, one of the two sprockets is a driving wheel and the other is a driven wheel. A motor drives the driving wheel to rotate, causing the chain 12 to rotate. The chain 12 drives the conveyor block 21 to move. Each time it passes through an arc-shaped section of the track 11, the conveyor block 21 undergoes a 180-degree turn, while the rotating shaft 20 is rotated relative to the conveyor block 21. The two ends of the rotating shaft 20 are fixedly connected to the guide assembly and the bracket 3. Under the combined action of the guide assembly and the different side walls of the track 11, the bracket 3 can be kept horizontal.

[0047] Typically, through holes are made in the float board to allow for ventilation during the breeding and seedling stage. In this design, the bracket 3 includes a connecting frame 33 and several support frames 31 connected to the connecting frame 33. The support frames 31 are connected to positioning posts 32. The positions of the positioning posts 32 correspond to the positions of the through holes on the float board. When the float board is supported on the bracket 3, the positioning posts 32 are located in the through holes, further preventing the float board from falling. In addition, the rotating shaft 20 is connected to the connecting frame 33 at the middle position to further maintain the stability of the float board.

[0048] As a preferred implementation method, combined with Figure 4 and Figure 5 As shown, the horizontal guide wheels include a first horizontal guide wheel 231 and a second horizontal guide wheel 232, which are respectively connected to both ends of the horizontal frame 23; the vertical guide wheels include a first vertical guide wheel 241 and a second vertical guide wheel 242, which are respectively connected to both ends of the vertical frame 24. The arrangement of two horizontal guide wheels and two vertical guide wheels allows the guide assembly to maintain better balance.

[0049] In another preferred embodiment, the first horizontal guide wheel 231 and the second horizontal guide wheel 232 are respectively arranged facing the front and rear sides; the first vertical guide wheel 241 and the second vertical guide wheel 242 are respectively arranged facing the front and rear sides. The first horizontal guide wheel 231 and the second horizontal guide wheel 232, as well as the first vertical guide wheel 241 and the second vertical guide wheel 242, are arranged in different directions. This configuration allows the horizontal and vertical guide wheels to automatically correct themselves if they become skewed during travel, thanks to the action of the guide wheels in different directions.

[0050] The terms "mounting", "arrangement", "provided with", "connected" should be interpreted broadly. For example, it can be fixed connection, detachable connection, or integral structure; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium, or internal communication between two devices, elements or components. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0051] The above describes the present application and its embodiments in a schematic manner, which is not restrictive, and the embodiments shown in the drawings are only one of the embodiments of the present application, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this, without departing from the creative purpose of the present application, similar structural modes and embodiments can be designed without creativity, which should belong to the protection scope of the present application.
