[0033] See also Figure 1-Figure 3 As shown, this embodiment is a rice seedling raising tray-laying machine, comprising:

[0034] A main assembly, the main assembly comprising a conveyor belt 12;

[0035] A standing plate 11 is connected to one end of the outer surface of the conveyor belt 12, a baffle 13 is fixed to one side of the outer surface of the conveyor belt 12, a film roller 14 is installed on the lower surface of the baffle 13, and a seedling tray 15 is placed on the upper surface of the conveyor belt 12;

[0036] The conveyor belt 12 is responsible for carrying and transporting the seedling tray 15, and realizes the smooth transmission of the seedling tray 15 from one end to the other end by cooperating with the driving device. The seedling tray 15 is the operating object of the entire main assembly;

[0037] The limiting assembly includes a motor 21, a support platform 211, a screw rod 22, a positive thread groove 23, a negative thread groove 231, and a first movable ring 24;

[0038] The motor 21 is mounted on one side of the outer surface of the conveyor belt 12, the support 211 is fixed on the lower surface of the motor 21, the thread passes through the screw rod 22 connected to the output end of the motor 21, the positive thread groove 23 is opened on one end of the outer surface of the screw rod 22, the reverse thread groove 231 is opened on the other side of the outer surface of the screw rod 22, and the first movable ring 24 passes through one side of the outer surface of the screw rod 22;

[0039] The motor 21 is installed on one side of the conveyor belt 12 as a power source, and is responsible for providing power to drive the entire limit assembly. When the motor 21 is started, the screw rod 22 will rotate, thereby driving the first movable ring 24 and the second movable ring 26 connected thereto to work. The positive thread groove 23 and the negative thread groove 231 are respectively provided on both sides of the screw rod 22. Their design enables the screw rod 22 to drive the first movable ring 24 and the second movable ring 26 in different directions when rotating, thereby realizing complex adjustment actions.

[0040] A first side plate 25 is fixedly connected to one side of the outer surface of the first movable ring 24, a second movable ring 26 is passed through the other side of the outer surface of the screw rod 22, a second side plate 27 is fixedly connected to one side of the outer surface of the second movable ring 26, a limiting rod 28 is passed through one side of the outer surface of the first side plate 25 and the second side plate 27, and a fixing block 29 is passed through one end of the screw rod 22;

[0041] The first side plate 25 and the second side plate 27 are connected to the screw rod 22 through the first movable ring 24 and the second movable ring 26. Their movement can adjust the effective width of the conveyor belt 12 to adapt to seedling trays 15 of different sizes and different ridges. The limit rod 28 is used to ensure that the two side plates move in parallel;

[0042] Working principle:

[0043] When the ridge width of the field becomes smaller;

[0044] The staff can start the motor 21 through the external control module, and the motor 21 will drive the screw rod 22 to rotate;

[0045] The screw rod 22 rotates, synchronously driving the positive thread groove 23 and the negative thread groove 231 to rotate. At this time, the first movable ring 24 and the second movable ring 26 move relative to each other, synchronously driving the first side plate 25 and the second side plate 27 to move toward the middle, shortening the width of the conveyor belt 12 to adapt to the width of the field ridge;

[0046] And under the limitation of the limiting rod 28, the first side plate 25 and the second side plate 27 move smoothly, so that the disc paving machine can work under different land conditions;

[0047] This step improves the applicability and flexibility of the machinery, making it highly adaptable and precise, able to work stably under different field conditions, improving operating efficiency and reducing costs, while also promoting the development of agricultural mechanization technology.

[0052] The function of the mounting groove 31 is to provide a fixed position for placing the connecting plate 32, thereby providing a stable support point for the entire anti-breakage assembly, and the main function of the connecting shaft 34 is to support the rotation of the connecting wheel 35;

[0053] The connecting wheel 35 is the part that directly contacts the seedling tray 15. When the seedling tray 15 is transmitted through the conveyor belt 12 and contacts the connecting wheel 35, the connecting wheel 35 can roll, thereby avoiding scratches or damage to the seedling tray 15 caused by excessive pressure;

[0054] Working principle:

[0055] When the seedling tray 15 is between the first side plate 25 and the second side plate 27 and is transported downward by the conveyor belt 12;

[0056] The side wall of the seedling tray 15 will contact the connecting wheel 35, and when the seedling tray 15 moves, the connecting shaft 34 rotates in the circular hole 33;

[0057] And drive the connecting wheel 35 to rotate, avoid damaging the outer surface of the seedling tray 15, not only protecting the seedling tray 15;

[0058] This step reduces damage and downtime, improves transmission stability, increases equipment applicability and operating quality, and reduces maintenance costs.
