Two guide plates 26 are arranged at one end of the mounting frame 2 located at the conveying assembly, and the conveying assembly is located between the two guide plates 26. By providing two guide plates 26, the seedling raising tray 1 can be moved out from between the two guide plates 26 during the process of the conveyor belt 16 conveying the seedling raising tray 1, thereby improving the stability and accuracy of the movement of the seedling raising tray 1.

[0048] The mounting frame 2 is provided with a second driving motor 21, and the transmission shaft of the second driving motor 21 is provided with a third sprocket; the driving shaft 17 is provided with a fourth sprocket 23, and the fourth sprocket 23 is connected to the third sprocket through a chain transmission.

[0049] Working principle:

[0050] In actual use, such as Figure 2As shown, the seedling tray stack is placed on the transport assembly, the seedling tray stack is located between the two limit baffles 29 and on the conveyor belt 32, the first drive motor 5, the second drive motor 21, and the third drive motor 34 are started, the third drive motor 34 drives the fifth sprocket 33 and the active transport shaft 30 to rotate simultaneously through the chain, and the active transport shaft 30 drives the conveyor belt 32 to move and transport the seedling tray stack on the top of the conveyor belt 32 into the installation frame 2. The seedling tray stack moves to abut against the limit baffle 36 and no longer moves. At the same time, the seedling tray stack is located between the four limit plates 35, which can improve the accuracy of the stop position of the seedling tray stack.

[0051] When the seedling tray stack moves into between the four limit plates 35, the third drive motor 34 stops working to wait for the next delivery of the seedling tray stack, and at the same time enters the seedling tray stack inside the mounting frame 2, and the bottom of the flange 27 corresponding to the lowest seedling tray 1 of the seedling tray stack abuts against the top of the dividing tray convex teeth 4. The first drive motor 5 drives the first sprocket 12 and the linkage shaft 7 to rotate simultaneously through the chain. Since the linkage shaft 7 is connected to the two first drive shafts 6 through bevel gears, and the two first drive shafts 6 are connected to the four dividing tray rotating shafts 3 through bevel gears, the four dividing tray rotating shafts 3 can be driven to rotate at the same time, and at this time, the four dividing tray convex teeth 4 are driven to rotate simultaneously through the dividing tray rotating shaft 3.

[0052] The cam 27 of the bottom third seedling tray 1 gradually moves downward and abuts the cam 4 of the dividing plate, and the cam 27 of the bottom third seedling tray 1 gradually moves downward and abuts the cam 4 of the dividing plate, and the cam 27 of the bottom third seedling tray 1 gradually moves downward and abuts the cam 4 of the dividing plate, ..., until the cam 27 of the bottom third seedling tray 1 gradually moves to the bottom of the cam 4 of the dividing plate, at this time, the cam 27 of the bottom third seedling tray 1 loses the support of the cam 4 of the dividing plate, and the cam 27 of the bottom third seedling tray 1 falls from the bottom of the cam 27 of the cam 27 of the dividing plate, and falls onto the conveyor belt 16 below. The cam 27 of the bottom fourth seedling tray 1 does not fall due to the support of the cam 4 of the dividing plate, and the separation of the cam 27 of the bottom fourth seedling tray 1 and the bottom fifth seedling tray 1 is completed.

[0053] The second driving motor 21 drives the fourth sprocket 23, the driving shaft 17 and the driving wheel 19 to rotate simultaneously through the chain. At this time, the conveyor belt 16 is driven to move through the driving wheel 19. The conveyor belt 16 can drive the seedling tray 1 that falls on the top of the conveyor belt 16 to move out from one side of the mounting frame 2. The mounting frame 2 can be connected to the rice planter, and the seedling tray 1 transmitted by the conveyor belt 16 can be directly transmitted to the rice planter for sowing operations.

[0054] When the seedling tray 1 is transported away by the conveyor belt 16, the second-to-last seedling tray 1 at the bottom falls onto the conveyor belt 16 and is transported out, and this cycle is repeated. The individual seedling trays 1 in the seedling tray stack can be automatically separated and sent to the rice planter in sequence. The operation is convenient, and the staff does not need to take out the individual seedling trays 1 from the seedling tray stack in sequence, which saves labor, improves work efficiency, and is conducive to the automated rice seedling cultivation. When the height of the seedling tray stack in the mounting frame 2 is gradually reduced until only one or two seedling trays 1 are left, the third drive motor 34 can be started to transport the next seedling tray stack to the mounting frame 2 to wait for separation, and this cycle is repeated.

[0055] like Figure 2-Figure 11 As shown, in some embodiments of the utility model, the above-mentioned mounting frame 2 is provided with a support shaft 24, the support shaft 24 is horizontally arranged and passes through the middle of the conveyor belt 16, the support shaft 24 is rotatably sleeved with a support pulley 25, and the conveyor belt 16 abuts against the top of the support pulley 25.

[0056] The utility model provides a supporting pulley 25 to support the conveyor belt 16, and further can support the seedling tray 1 conveyed on the top of the conveyor belt 16, to prevent the seedling tray 1 from squeezing the conveyor belt 16 and causing the conveyor belt 16 to deform too much, thereby facilitating the transmission of the seedling tray 1.

[0057] like Figure 2-Figure 11 As shown, in some embodiments of the utility model, the above-mentioned mounting frame 2 is provided with two tray assemblies at intervals, and the tray assemblies correspond to the two sub-disk assemblies one by one; the tray assembly includes a vertical shaft 38 and a mounting sleeve 37 provided on the mounting frame 2, and the vertical shaft 38 rotates through the mounting sleeve 37; the bottom end of the vertical shaft 38 is provided with a fifth bevel gear 39, and the top end of the vertical shaft 38 is provided with a seventh sprocket 40; a tray drive shaft 41 is provided between the two tray assemblies, and the tray drive shaft 41 is rotatably provided on the mounting frame 2 through the bearing seat 15, and both ends of the tray drive shaft 41 are provided with a sixth bevel gear 42 meshing with the fifth bevel gear 39; the tray drive shaft 41 is provided with an eighth sprocket 43, and the mounting frame 2 is provided with a fourth drive motor 44, and the transmission shaft of the fourth drive motor 44 is provided with a ninth sprocket, and the ninth sprocket is connected to the eighth sprocket 43 through a chain transmission;

[0058] A rotating sleeve 45 is rotatably sleeved on the outside of the vertical rotating shaft 38, and a driving arm 46 and a swing arm 47 are arranged opposite to the rotating sleeve 45. A mounting bearing 48 is arranged on the top of the swing arm 47, and the inner ring of the mounting bearing 48 is fixed to the top of the swing arm 47. A tenth sprocket 49 and a storage tray 50 are fixed on the outer ring of the mounting bearing 48. The tenth sprocket 49 is connected to the seventh sprocket 40 through a chain transmission.

[0059] The utility model also includes two cylinders 13, and the number of the cylinders 13 is one-to-one corresponding to the two tray assemblies; one end of the cylinder 13 is rotatably connected to the mounting frame 2, and the other end of the cylinder 13 is rotatably connected to the driving arm 46. The mounting frame 2 is provided with a supporting pad 14, and the end of the swing arm 47 away from the rotating sleeve 45 is rotatably provided with a pulley 22, and the pulley 22 is slidably arranged on the top of the supporting pad 14.

[0060] The utility model provides a tray assembly, and when the transport assembly transports the seedling tray stack into the installation frame 2, the seedling tray stack can be supported by the storage tray 50 of the tray assembly, thereby improving the stability of the movement of the seedling tray stack. The working principle of the tray assembly is as follows:

[0061] When the transport assembly has not yet transported the stack of seedling trays, the cylinder 13 shortens and pulls the driving arm 46 to rotate, and the driving arm 46 pulls the rotating sleeve 45 to rotate along the vertical rotating shaft 38 to make the swing arm 47 rotate toward the outside of the mounting frame 2. At this time, the swing arm 47 drives the storage tray 50 to move toward the outside of the mounting frame 2 to keep the storage tray 50 away from the stack of seedling trays inside the mounting frame 2.

[0062] When the transport assembly transports the stack of seedling trays into the interior of the mounting frame 2, the cylinder 13 extends and pushes the driving arm 46 to rotate, and the driving arm 46 pushes the rotating sleeve 45 to rotate along the vertical rotating shaft 38 to make the swing arm 47 rotate toward the inside of the mounting frame 2. At this time, the swing arm 47 drives the storage tray 50 to move toward the inside of the mounting frame 2 so that the storage tray 50 moves into the interior of the mounting frame 2, and then the cylinder 13 is stopped. After the transport assembly transports the stack of seedling trays into the interior of the mounting frame 2, the stack of seedling trays is located on top of the two storage trays 50, and the stack of seedling trays is supported by the two storage trays 50.

[0063] At the same time, the fourth drive motor 44 is started, and the fourth drive motor 44 drives the eighth sprocket 43 and the tray drive shaft 41 to rotate simultaneously through the chain. Since the tray drive shaft 41 is meshed with the vertical shaft 38 through the bevel gear, the two vertical shafts 38 can be driven to rotate. Since the seventh sprocket 40 is arranged on the top of the vertical shaft 38, the seventh sprocket 40 is connected with the tenth sprocket 49 through the chain transmission, the rotating vertical shaft 38 drives the tenth sprocket 49 and the outer ring of the mounting bearing 48 to rotate, and drives the storage tray 50 to rotate through the outer ring of the mounting bearing 48. Since the seedling tray stack is located on the top of the storage tray 50, under the action of the friction between the seedling tray stack and the storage tray 50, the rotating storage tray 50 can drive the seedling tray stack to move toward the side of the limit stop rod 36 until the seedling tray stack moves to abut against the limit stop rod 36. At this time, the seedling tray stack moves to the set position, and then the fourth drive motor 44 is turned off, the cylinder 13 is started, the cylinder 13 is shortened to allow the storage tray 50 to move out from the bottom of the seedling tray stack, and the cylinder 13 is turned off, waiting for the next seedling tray stack to be transported into the installation frame 2 by the transport assembly.
