[0002] Seedling raising is a crucial and fundamental step in rice cultivation. Through steps such as seed selection, soaking and germination, sowing and seedling raising, robust seedlings are cultivated. Traditionally, this relied on natural conditions, but modern methods often use greenhouses, mechanized seedling raising lines, and other technologies to regulate temperature and humidity, improve efficiency and seedling quality, and lay the foundation for high and stable rice yields.

[0003] The track-type harvesting platform runs along a preset track, ensuring high stability and smooth operation. It is suitable for harvesting fruits and vegetables cultivated over long seasons. The platform can be hydraulically lifted, with an operating height of several meters, facilitating operations such as pruning, removing forks, and harvesting. Although track laying requires certain costs, it improves harvesting efficiency and reduces labor intensity, making it an important manifestation of modern agricultural mechanization and intelligence.

[0004] In order to improve the efficiency of workers during the rice seedling harvesting process, the interior of the greenhouse is usually equipped with a track with a moving platform. Workers stand on the platform and use sickles to harvest the rice. However, after the storage boxes on the platform are full of rice, the moving platform needs to be moved back to the starting position to load and unload the boxes. Moving the platform back and forth is too time-consuming and affects the efficiency of rice harvesting. Therefore, this utility model proposes a track-type harvesting platform for rice seedling centers to solve the above problems. Utility Model Content

Detailed Implementation

[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] according to Figure 1 , 2As shown in Figures 3 and 4, this embodiment proposes a track-type harvesting platform for a seedling raising center, including a No. 1 vehicle 1, a No. 2 vehicle 2, and a No. 3 vehicle 3. The No. 2 vehicle 2 is located on one side of the No. 1 vehicle 1, and the No. 3 vehicle 3 is located on one side of the No. 2 vehicle 2. A support frame 4 is fixedly connected to the top of each of the No. 1, No. 2, and No. 3 vehicles. A limiting mechanism is provided at the top of the support frame 4. A driving mechanism is provided on one side of the bottom of each of the No. 1 and No. 3 vehicles. A connecting mechanism is provided between the No. 1, No. 2, and No. 3 vehicles. In use, the worker stands on top of the No. 1 vehicle 1, and the No. 1 and No. 2 vehicles are connected as one unit via the connecting mechanism. The storage frame is stably placed on top of the support frame 4 by the limiting mechanism, and driven by the driving mechanism. Car 1, Car 2, and Car 3 move within the track, facilitating rice harvesting during the movement. Once the storage box is full of rice, it is removed from the limiting mechanism of Car 1 and moved to the limiting mechanism of Car 2. Then, the empty storage box on Car 3 is removed and clamped in the limiting mechanism of Car 1, disconnecting Car 1 from Car 2. Car 3 then drives Car 2 back to the starting point, removing the storage box from the limiting mechanism of Car 2 and fixing the empty storage box in the limiting mechanism of Car 3. Car 3 then drives Car 2 to reset, restoring the connection between Car 1 and Car 2. During this process, employees do not need to move back and forth waiting for new storage boxes, improving the efficiency of rice harvesting.

[0021] The connecting mechanism includes a connecting hook 5, a limiting frame 6, a telescopic rod 7, a pressure plate 8, and a spring 9. Connecting hooks 5 are hinged to one side of the first car 1 and the third car 3. Limiting frames 6 are symmetrically fixedly connected to both sides of the second car 2. One end of each of the two connecting hooks 5 is engaged with one side of each of the two limiting frames 6. Telescopic rods 7 are symmetrically fixedly connected to the other side of each limiting frame 6. A pressure plate 8 is fixedly connected to one end of each telescopic rod 7. A spring 9 is provided on the outer side of the telescopic rod 7. Moving the pressure plate 8 towards the limiting frame 6 increases the gap between the pressure plate 8 and one side of the limiting frame 6. Rotating one end of the connecting hook 5 allows it to enter the limiting frame. Move one side of the positioning frame 6 and move the positions of car 1 and car 2 or car 3 and car 2 so that one end of the connecting hook 5 and one side of the positioning frame 6 are engaged together, and the telescopic rod 7 and spring 9 are in a compressed state. After releasing, the elastic force generated by spring 9 drives the pressure plate 8 to return to its original position. The pressure plate 8 and the positioning frame 6 cooperate to clamp one end of the connecting hook 5, so as to connect the connecting hook 5 and the positioning frame 6 together. At this time, one side of car 2 can be connected to car 1, or the other side of car 2 can be connected to car 3, so that car 2 moves with car 1 or car 3.

[0022] The No. 1 car, No. 2 car, and No. 3 car include pressure plates and rollers. A set of rollers is symmetrically fixedly installed on the bottom of the pressure plate, and the pressure plate is slidably connected to the track through the rollers.

[0023] The drive mechanism includes a self-locking motor 10, a rotating shaft 11, a first bevel gear 12, and a second bevel gear 13. A self-locking motor 10 is fixedly installed on one side of the first car 1 and the third car 3. A rotating shaft 11 connects a set of rollers. A second bevel gear 13 is fixedly connected to the outer side of the rotating shaft 11. A self-locking motor 10 is also fixedly installed on one side of the first car 1 and the third car 3. The output end of the self-locking motor 10 passes through the bottom of the pressure plate of the first car 1 and is fixedly connected to the first bevel gear 12. The first bevel gear 12 and the second bevel gear 13... The outer walls of the three cars mesh with each other. The output end of the self-locking motor 10 can drive the first bevel gear 12 to rotate on one side of the bottom of the first car 1 or the third car 3. The first bevel gear 12 meshes with the second bevel gear 13, and the second bevel gear 13 is connected to the rotating shaft 11 as a whole. The self-locking motor 10 can drive the rotating shaft 11 to rotate. The two ends of the rotating shaft 11 are connected to two rollers respectively, which are used to drive the two rollers to rotate automatically, thereby driving the first car 1 or the third car 3 to move automatically. The forward and reverse rotation of the self-locking motor 10 can control the first car 1 or the third car 3 to move forward or backward.

[0024] The first vehicle 1 and the third vehicle 3 are equipped with a protective shell on one side. The self-locking motor 10 is wrapped inside the protective shell. Multiple anti-collision strips are fixedly connected to the outside of the protective shell. The protective shell and anti-collision strips can isolate the self-locking motor 10 from external objects, prevent external objects from directly contacting the self-locking motor 10, and protect the self-locking motor 10.

[0025] The limiting mechanism includes a sliding groove 14, clamping plates 15, and adjusting bolts 16. The top of the support frame 4 is provided with a sliding groove 14. Adjusting bolts 16 are symmetrically slidably connected to both sides of the sliding groove 14. Clamping plates 15 are fixedly connected to the outer side of the adjusting bolts 16. Nuts are threaded to both ends of the adjusting bolts 16. Loosening the nuts at both ends of the adjusting bolts 16 releases the restriction between the adjusting bolts 16 and the top of the support frame 4. The adjusting bolts 16 can move back and forth in a straight line along the sliding groove 14 until the two clamping plates 15 are attached to both sides of the storage frame. The L-shaped clamping plates 15 can avoid the outer edge of the top of the storage frame and directly limit it. Then, tighten the nuts at both ends of the adjusting bolts 16 to lock the position of the two clamping plates 15, so that the storage frame is stably placed on the top of vehicle 1, vehicle 2, and vehicle 3. When moving the storage frame, loosen the nuts again to move the clamping plates 15 away from the storage frame and release the restriction of the clamping plates 15 on the storage frame.

[0026] The clamping plate 15 has a groove 17 inside, and a tensioning rod 18 is hinged inside the groove 17. A cylinder is fixedly connected to the top of the tensioning rod 18. A threaded rod 19 is threadedly connected to the top of the clamping plate 15. A wedge block 20 is rotatably connected to the bottom of the threaded rod 19. The bottom of the wedge block 20 is fitted against the outer side of the cylinder. During the movement of vehicles 1, 2, and 3, they may be subjected to external impacts that cause the vehicle bodies to vibrate. If the storage frame is only supported by the limiting mechanism, it may fall off the top of them. Turning the threaded rod 19 in the forward direction will cause the wedge block 20 to move. Moving downwards, the wedge block 20 presses the top of the tension rod 18, causing its bottom to rotate outwards towards the storage frame. After the bottom of the tension rod 18 fits against the storage frame, it can clamp it, thus fixing the storage frame on top of vehicle 1, vehicle 2, and vehicle 3. When moving the storage frame, the threaded rod 19 is turned in the opposite direction, causing the wedge block 20 to move upwards. After the wedge block 20 separates from the top of the tension rod 18, no more pressure is applied to it. The bottom of the tension rod 18 rotates downwards due to gravity and separates from the storage frame, making it convenient for employees to remove the storage frame from the top of vehicle 1, vehicle 2, and vehicle 3.

[0027] The track-type harvesting platform moves the pressure plate 8 towards the limiting frame 6, increasing the gap between the pressure plate 8 and one side of the limiting frame 6. Rotating one end of the connecting hook 5 allows it to enter one side of the limiting frame 6, and the positions of car 1 and car 2, or car 3 and car 2, are adjusted so that one end of the connecting hook 5 and one side of the limiting frame 6 are engaged. The telescopic rod 7 and spring 9 are compressed. Releasing the lever allows the spring force of spring 9 to reset the pressure plate 8. The pressure plate 8, in conjunction with the limiting frame 6, clamps one end of the connecting hook 5, connecting it to the limiting frame 6. At this point, one side of car 2 can connect to car 1, or... On the other side of vehicle 2, it connects to vehicle 3. After the storage box is filled with rice, it is removed from the limiting mechanism of vehicle 1 and moved to vehicle 2. Then, the empty storage box on vehicle 3 is removed and clamped in vehicle 1, disconnecting vehicle 1 from vehicle 2. Vehicle 3 then drives vehicle 2 back to the starting point. After removing the storage box from vehicle 2, the empty storage box is fixed on vehicle 3. Vehicle 3 then drives vehicle 2 to reset, restoring the connection between vehicle 1 and vehicle 2. During this process, employees do not need to move back and forth to wait for a new storage box, improving the efficiency of rice harvesting.
