Description

Technical Field

[0001] This application relates to the technical field of rice seedling transfer, and in particular to a rice seedling transfer device for rice cultivation. Background Technology

[0002] As one of the world's major food crops, the efficient transportation of rice seedlings is a crucial factor affecting planting efficiency and yield. Traditional rice seedling transportation relies mainly on manual handling or transport carts. While transport carts offer better efficiency and require less labor compared to manual handling, the current transport carts have simple structures and lack effective protection for the seedlings during transport. Workers simply stack seedling trays on the cart's placement platform, causing the seedlings to be squeezed together. Furthermore, the bumpy transport process can easily lead to misalignment and friction between the seedlings, resulting in damage and affecting survival rates.

[0003] Therefore, those skilled in the art have provided a rice seedling transfer device for rice cultivation to solve the problems mentioned in the background art. Utility Model Content

[0004] To address the problems mentioned in the background art, this application provides a rice seedling transfer device for rice cultivation.

[0005] The rice seedling transfer device for rice cultivation provided in this application adopts the following technical solution:

[0006] A rice seedling transfer device for rice cultivation includes a base plate. A handrail is installed on one side of the upper surface of the base plate. Multiple threaded rods are installed on both sides of the upper surface of the base plate. Multiple pads are sleeved between two threaded rods. Multiple U-shaped grooves are equidistantly installed on the upper surface of the pads, and the multiple U-shaped grooves are arranged opposite each other in pairs. The base plate is fixedly connected to the two corners of the multiple pads. A crossbar is fixedly connected between the outer sides of the multiple rows of U-shaped grooves. Adjusting sleeves are installed at the two corners of the crossbar, and the two end adjusting sleeves are respectively sleeved on the outside of the corresponding end adjusting rods. A limiting component is provided below the adjusting sleeve.

[0007] Preferably, the limiting component includes a U-shaped part and a limiting bolt. The U-shaped part is fixed to the lower surface of the adjusting sleeve, the limiting bolt is threaded to the lower part of the U-shaped part, and one end of the U-shaped part abuts against the lower surface of the adjusting rod.

[0008] Preferably, each of the sides of the multiple crossbars is equipped with a protrusion, and the multiple protrusions in the same row are connected by a through rod, with the bottom of the through rod overlapping the surface of the base plate.

[0009] Preferably, the multiple threaded rods are externally threaded with multiple threaded sleeves, and an annular plate overlaps the upper surface of the multiple threaded sleeves. A spring is elastically connected between the annular plate and the pad.

[0010] Preferably, a circular hole is provided at the center of the annular plate.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. By controlling the lateral movement of multiple crossbars, the outermost rows of U-shaped grooves can move on the upper surface of the pad. The distance between two U-shaped grooves in relative positions is adjusted so that the two U-shaped grooves match the specifications of the seedling trays to be transported. With the top of the limit bolt abutting against the lower surface of the adjusting rod, the adjusted position of the multiple rows of U-shaped grooves is fixed, making it easy to place the seedling trays one by one between the two adjusted U-shaped grooves. This not only limits the seedling trays one by one, but also avoids the seedling trays directly stacking on each other, reducing the damage to the seedlings caused by misalignment and friction during transport, and improving the protection of the seedlings during transport. Furthermore, the spring elastic connection between the ring plate and the pad provides cushioning for the seedlings when they are transported on bumpy sections, further improving the protection of the seedlings.

[0013] 2. By using the through rod and the protrusion, the height adjustment of the U-shaped groove is not affected, and the operator can move the multiple rows of U-shaped grooves on the outer side laterally at the same time without having to move and adjust each row of U-shaped grooves one by one, thus improving the convenience of the device during use.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] refer to Figures 1-4 As shown, this application discloses a rice seedling transfer device for rice cultivation, including a base plate 1 with rollers at four corners. A handrail 2 is installed on one side of the upper surface of the base plate 1 for easy control of the device's movement. Multiple threaded rods 4 are installed on both sides of the upper surface of the base plate 1, with multiple pads 12 connected between two threaded rods 4. Multiple U-shaped grooves 3 are equidistantly installed on the upper surface of the pads 12, arranged in pairs opposite each other. The innermost U-shaped groove 3 is fixed to the upper surface of the pad 12, while the outermost adjusting sleeve 13 overlaps the upper surface of the pad 12 to facilitate lateral movement of one side of the U-shaped groove 3 and adjust the distance between the two adjusting sleeves 13. This device is adaptable to different seedling tray sizes.

[0021] Meanwhile, base plates 1 are fixedly connected to the two corners of multiple pads 12, and crossbars 10 are fixedly connected between the outermost rows of U-shaped grooves 3. Adjusting sleeves 13 are installed at the two corners of the crossbars 10, and the two ends of the adjusting sleeves 13 are respectively sleeved on the outside of the corresponding end adjusting rods 11. A limiting component is provided below the adjusting sleeves 13. By moving the multiple crossbars 10 laterally, the outermost rows of U-shaped grooves 3 can move on the upper surface of the pads 12, adjusting the distance between the two U-shaped grooves 3 in relative positions, so that the two U-shaped grooves 3 match the specifications of the seedling trays to be transported, which is convenient to adapt to the specifications of more seedling trays of different sizes. At the same time, with the help of the limiting component, it is easy to limit the adjusting sleeves 13 and the crossbars 10, ensuring that the multi-row U-shaped grooves 3 are fixed after the position is adjusted.

[0022] refer to Figure 4 As shown, the limiting assembly includes a U-shaped part 14 and a limiting bolt 15. The U-shaped part 14 is fixed on the lower surface of the adjusting sleeve 13, and the limiting bolt 15 is threadedly connected to the lower part of the U-shaped part 14. One end of the U-shaped part 14 abuts against the lower surface of the adjusting rod 11, which facilitates the limiting of the adjusting sleeve 13 and ensures that the moving position of the outer multi-row U-shaped groove 3 is fixed in time.

[0023] refer to Figure 3 and Figure 4As shown, multiple crossbars 10 have protrusions 9 installed at both ends of their sides. Multiple protrusions 9 in the same row pass through a through rod 5, and the bottom of the through rod 5 overlaps the upper surface of the base plate 1. Through the cooperation of the through rod 5 and the protrusions 9, the height adjustment of the U-shaped groove 3 is not affected, and the operator can simultaneously move the multiple rows of U-shaped grooves 3 on the outer side laterally without having to move and adjust each row of U-shaped grooves 3 sequentially, thus improving the convenience of the device during use.

[0024] refer to Figure 2 and Figure 3 as well as Figure 4 As shown, multiple threaded rods 4 are externally threaded with multiple threaded sleeves 6. Annular plates 7 overlap the upper surfaces of the multiple threaded sleeves 6. Springs 8 are elastically connected between the annular plates 7 and the pads 12. The threaded sleeves 6 can limit the position of the annular plates 7, making it easy to adjust the distance between the multiple pads 12 and the U-shaped grooves 3, which can easily adapt to the height of different batches of seedlings. At the same time, the springs 8 can buffer the seedlings when they are transported on bumpy roads, further improving the protection of the seedlings.

[0025] refer to Figure 4 As shown, a circular hole is provided at the center of the annular plate 7 to facilitate the movement of the annular plate 7 outside the threaded rod 4.

[0026] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0028] The implementation principle of a rice seedling transfer device for rice planting according to an embodiment of this application is as follows:

[0029] During transport, multiple crossbars 10 are pulled laterally to allow the outermost rows of U-shaped grooves 3 to move on the upper surface of the pad 12. The distance between the two U-shaped grooves 3 is adjusted to match the size of the seedling trays to be transported. Then, multiple limiting bolts 15 are tightened in sequence so that the top of the limiting bolts 15 is inserted into the adjusting sleeve 13 and abuts against the lower surface of the adjusting rod 11. This facilitates the limiting of the adjusting sleeve 13 and the crossbars 10, ensuring that the rows of U-shaped grooves 3 are fixed after adjustment. Then, the seedling trays can be placed between the two adjusted U-shaped grooves 3 one by one. This not only limits the seedling trays one by one, but also avoids the seedling trays from being directly stacked on top of each other, reducing the damage to the seedlings caused by misalignment and friction during transport, and improving the protection of the seedlings during transport.
