[0002] The seedling raising tray is an important tool for cultivating seedlings in the process of rice planting, which helps to improve seedling raising efficiency, ensure seedling quality, and facilitate mechanized transplanting. The seedling raising tray is generally divided into hard seedling raising trays and soft seedling raising trays. The hard seedling raising tray has high strength and durability, is suitable for large-scale repeated use, the soft seedling raising tray is light and easy to fold, and is convenient for transportation and storage, but is relatively not so solid and has a short service life.

[0003] When the hard seedling raising tray is used for seedling raising, the rice seeds are spread in the tray, and the number of rice placed at one time is limited. The rice is not separated, which causes the roots of the rice to easily entangle together. When the rice is taken out, the roots of the rice grow in disorder, which easily breaks in the process of taking out. If the hard seedling raising tray is not properly stacked after use, it will occupy a large storage space and increase the storage cost. The hard seedling raising tray may be broken or deformed when improperly used or subjected to external force impact, which affects the service life. SUMMARY

[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-4 As shown, a bottomless rice seedling tray for rice cultivation includes: a seedling tray 1, with a fixing groove 2 inside the seedling tray 1; a positioning component set at the bottom of the seedling tray 1, the positioning component including: a first leg 101, a positioning groove 102, and a second leg 103; and a pressing component set inside the seedling tray 1, the pressing component including: a spring a201, a connecting plate 3, a connecting block 4, a spring b401, and a pressing block 402.

[0023] The positioning components ensure that the second support 103 and the positioning groove 102 can interlock when the seedling trays 1 are stacked, preventing misalignment and increasing the stability of the stacked trays. The compression components ensure that the seedlings grow individually within the seedling chamber 5, forming intact seedling blocks. This prevents the roots from intersecting and avoids damage to the roots during seedling separation, thus improving the seedling survival rate.

[0024] The seedling tray 1 has a first bracket 101 fixedly installed at the bottom, a positioning groove 102 opened at the top of the seedling tray 1, the positioning groove 102 is deeper on one side and has a semi-circular cross-section, and a second bracket 103 fixedly installed at the bottom of the seedling tray 1.

[0025] When stacking seedling trays 1, the second leg 103 of one seedling tray 1 is placed into the positioning groove 102 of another seedling tray 1. Since one side of the positioning groove 102 is deeper than the other, the second leg 103 will slide from the shallower part of the positioning groove 102 to the deeper part, thereby making the two seedling trays 1 interlocked. This fixes the two seedling trays 1 together and achieves a positioning effect, preventing misalignment when stacking the seedling trays 1, which would reduce the stability of the seedling trays 1. The first leg 101 increases the friction between the seedling trays 1, increases the stability of the seedling trays 1 when stacked, prevents the seedling trays 1 from slipping when stacked, and leaves space for the rice seedlings to avoid squeezing the seedlings.

[0026] The fixed groove 2 is internally provided with a plurality of springs a201, one end of the spring a201 is connected with the inner wall of the fixed groove 2, the plurality of springs a201 are uniformly distributed in the horizontal direction, the top of the spring a201 is fixedly connected with the connecting plate 3, the inside of the seedling raising tray 1 is provided with two sliding grooves 301, the inside of the seedling raising tray 1 is provided with a plurality of connecting holes 302, the top of the connecting plate 3 is fixedly connected with a plurality of connecting rods 303, a rotating rod 304 is rotatably connected between every two connecting rods 303, a plurality of connecting blocks 4 are fixedly installed on the top of the connecting plate 3, a plurality of springs b401 are fixedly installed on the top of the connecting block 4, an extrusion block 402 is fixedly connected with the top of the spring b401, a plurality of seedling raising cavities 5 are formed in the top of the seedling raising tray 1, and a limiting block 501 is fixedly installed in the bottom of each seedling raising cavity 5.

[0027] When the seedlings are raised, the rice seeds are placed in the seedling raising cavities 5, through the arrangement of the seedling raising cavities 5, the rice seeds can grow into seedling blocks, and the root systems of the seedlings will not cross each other, when the seedlings are separated, the rotating rod 304 is rotated, then the rotating rod 304 is pulled upwards, an upward pulling force is applied to the rotating rod 304, the rotating rod 304 pulls the connecting rod 303, so that the connecting plate 3 moves upwards, the connecting plate 3 moves upwards, the spring a201 is stretched to generate elastic force, at the same time, the connecting block 4 moves upwards to extrude the spring b401, the elastic force generated by the extrusion of the spring b401 pushes the extrusion block 402 to slide in the seedling raising cavity 5, so that the extrusion block 402 extrudes the seedling block upwards, the seedling block can be completely extruded out of the seedling raising cavity 5, the seedlings are prevented from being pulled out and damaged when the staff takes the seedlings, after the seedlings are taken out, the rotating rod 304 is loosened, the pulling force disappears, the elastic force generated by the spring a201 pulls the connecting plate 3 to move downwards, so that the connecting block 4 pulls the spring b401 to stretch downwards, the elastic force generated by the stretching of the spring b401 can pull the extrusion block 402 to move downwards, and the limiting block 501 can limit the extrusion block 402 to prevent the extrusion block 402 from being pulled into the fixed groove 2 by the spring b401.

[0028] Working principle:

[0029] When the seedling trays 1 are stacked, the second foot 103 of one seedling tray 1 is placed into the positioning groove 102 of another seedling tray 1. Since the positioning groove 102 is deeper on one side and shallower on the other side, the second foot 103 will slide from the shallow side to the deep side of the positioning groove 102, so that the two seedling trays 1 are clamped with each other, thereby being fixed with each other, achieving the positioning effect, avoiding mispositioning when the seedling trays 1 are stacked, and reducing the stability of the seedling trays 1. The first foot 101 increases the friction between the seedling trays 1, increases the stability of the seedling trays 1 when stacked, avoids the seedling trays 1 from falling when stacked, and reserves space for rice seedlings, avoiding the rice seedlings from being squeezed. When the seedlings are cultivated, the rice seeds are placed in the seedling cavities 5. Through the arrangement of the seedling cavities 5, the rice seeds can grow into seedling blocks, and the root systems of the seedlings will not intersect with each other. When the seedlings are separated, the rotating rod 304 is rotated, and then the rotating rod 304 is pulled upward, so that an upward pulling force is applied to the rotating rod 304, the rotating rod 304 pulls the connecting rod 303, thereby driving the connecting plate 3 to move upward. The upward movement of the connecting plate 3 causes the spring a 201 to stretch and generate elastic force, and causes the connecting block 4 to move upward and squeeze the spring b 401. The elastic force generated by the spring b 401 due to the squeezing pushes the squeezing block 402 to slide in the seedling cavity 5, so that the squeezing block 402 squeezes the seedling block upward, and the seedling block can be completely squeezed out of the seedling cavity 5, avoiding the seedlings from being pulled out by the staff and damaged. After the seedlings are taken out, the rotating rod 304 is released, and the elastic force generated by the spring a 201 pulls the connecting plate 3 to move downward, so that the connecting block 4 pulls the spring b 401 to stretch downward, the elastic force generated by the stretching of the spring b 401 pulls the squeezing block 402 to move downward, and the limiting block 501 limits the movement of the squeezing block 402 to prevent the squeezing block 402 from being pulled into the fixed groove 2 by the spring b 401.
