Description

Technical Field

[0001] This utility model relates to the field of rice seedling technology, and more specifically, it relates to a bottomless rice seedling tray for rice cultivation. Background Technology

[0002] In the existing technology, there are still some shortcomings in the structural design and ease of use of a bottomless rice seedling tray for rice planting. The main shortcomings are that the connection between the various trays is not convenient enough, and the installation and disassembly process of the tray and the soaking cylinder is relatively complicated.

[0003] First, the connection between the various trays is inconvenient. Existing bottomless seedling trays are usually composed of multiple independent trays, which can be expanded or spliced ​​according to the seedling area or seedling needs. However, in practical applications, these trays are mostly connected by simple snap-fit ​​or plug-in structures. During assembly, manual alignment and force pressing are required, which is cumbersome and inefficient.

[0004] Secondly, the installation and disassembly of the tray and the soaking cylinder are inconvenient. Bottomless seedling trays are typically used with a soaking cylinder to provide nutrients and moisture to the substrate or seedling material in the tray through soaking or spraying. However, in existing designs, the connection structure between the tray and the soaking cylinder is quite complex, usually requiring threaded tightening, snap ring fixing, or screw locking. In practice, installation and disassembly are difficult, especially when frequent cleaning, replacement, or maintenance is needed. Operators must use tools to complete the assembly and disassembly, resulting in low efficiency. Utility Model Content

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a bottomless rice seedling tray for rice cultivation, comprising an installation plate, a tray installation mechanism, an installation clamping mechanism, and a stabilizing mechanism. The tray installation mechanism includes a liquid-soaked bottom cylinder and a seedling tray body. A top plate is installed at the outer end of the seedling tray body, and a bottom plate is installed at the outer end of the liquid-soaked bottom cylinder. A clamping tube is fixedly installed on the top plate. A clamping rod is slidably installed on the installation plate. One end of the clamping rod can pass through the bottom plate, the installation plate, and the top plate, and extend into the clamping tube for clamping. The installation clamping mechanism includes a locking rod and an outer moving block. The outer moving block is slidably installed laterally on the outer wall of the clamping tube. A locking rod is installed at one end of the outer moving block. A clamping groove is opened on the outer wall of the locking rod. An outer rotating frame is rotatably installed on the outer wall of the clamping tube. A sealing block and an unlocking block are installed on the outer rotating frame. The sealing block can press against the outer moving block, causing the locking rod to extend into the clamping groove. The outer rotating frame is rotated in the opposite direction, causing the locking rod to move away from the clamping groove.

[0007] The present invention is further configured such that the stabilizing mechanism includes an outer fixed ring and a pair of shrink blocks. The outer fixed ring is fixedly installed on the outer wall of the clamping tube. The pair of shrink blocks are slidably installed on the outer fixed ring, and multiple sets of rings are arranged in pairs. A shrink spring is installed between the pairs of shrink blocks. A rotating ball block is installed on one end face of the outer rotating frame. The rotating ball block passes through the pairs of shrink blocks in sequence, so that the outer rotating frame rotates stably on the outer wall of the clamping tube.

[0008] The present invention is further configured such that a splicing groove is provided on one end face of the mounting plate, and a splicing block is installed on one end face of the mounting plate.

[0009] The present invention is further configured such that the mounting plate is provided in multiple sets, and the interlocking blocks can be embedded in the interlocking slots to connect adjacent mounting plates. The interlocking blocks and the interlocking slots are respectively installed and opened on the end face of the mounting plate to realize the rapid connection of multiple sets of mounting plates.

[0010] The present invention is further configured such that a connecting plate is installed at the bottom end of the mounting plate, and the mounting bolt can pass through the mounting plate and the connecting plate to fix adjacent mounting plates. The connecting plate is installed at the bottom of the mounting plate and works with the mounting bolt to fix adjacent mounting plates.

[0011] The present invention is further configured such that a connecting plate is installed on the side wall of the card tube, and the connecting plate is fixedly installed on the top plate. The connecting plate is installed on the side wall of the card tube to fix the card tube on the top plate.

[0012] The present invention is further configured such that an end block is installed at one end of the snap-fit ​​rod, and the end block can contact one end face of the chassis. The end block is installed at one end of the snap-fit ​​rod and provides positioning support by contacting the end face of the chassis.

[0013] The present invention is further configured such that a push-in spring is installed between the outer wall of the outer moving block and the outer wall of the locking tube, and the push-in spring is installed between the outer moving block and the outer wall of the locking tube to provide a driving force for the locking rod to be embedded.

[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides a bottomless rice seedling tray for rice cultivation, which has the following beneficial effects: This utility model is equipped with a tray installation mechanism. The seedling tray body cooperates with the clamping pipe and clamping rod on the top plate. The liquid-soaking bottom cylinder is positioned by the base plate. The clamping rod slides on the mounting plate and passes through the base plate, the mounting plate and the top plate to extend into the clamping pipe, so as to realize the combined installation and precise positioning of the seedling tray body and the liquid-soaking bottom cylinder on the mounting plate.

[0015] This utility model is equipped with an installation snap-fit ​​mechanism. When the outer rotating frame is rotated, the sealing block presses against the outer moving block, and the pushing spring drives the outer moving block to slide laterally so that the locking rod extends into the snap-fit ​​rod's outer wall slot to achieve a firm lock. When rotated in the opposite direction, the unlocking block acts to make the locking rod move away from the slot and quickly unlock, thus achieving a reliable connection and convenient disassembly / reassembly between the seedling tray and the soaking bottom cylinder.

[0016] This invention features a stabilizing mechanism. When the outer rotating frame rotates, the rotating ball blocks pass sequentially between pairs of contraction blocks on the outer fixed ring. The contraction springs cause the contraction blocks to contract centripetally, generating a clamping force on the rotating ball blocks. This creates staged positioning feedback and rotational resistance, ensuring that the outer rotating frame rotates smoothly and accurately on the outer wall of the clamping tube, thus improving the controllability and precision of the clamping operation.

[0022] Please see Figures 1-5 A bottomless rice seedling tray for rice cultivation includes an installation plate 1, a tray installation mechanism, an installation clamping mechanism, and a stabilizing mechanism. The tray installation mechanism includes a liquid-soaked bottom cylinder 2 and a seedling tray body 3. A top plate 4 is installed at the outer end of the seedling tray body 3, and a bottom plate 5 is installed at the outer end of the liquid-soaked bottom cylinder 2. A clamping pipe 6 is fixedly installed on the top plate 4. A clamping rod 7 is slidably installed on the installation plate 1. One end of the clamping rod 7 can pass through the bottom plate 5, the installation plate 1, and the top plate 4, and extend into the clamping pipe 6 to cooperate. The locking mechanism includes a locking rod 8 and an outer moving block 9. The outer moving block 9 is laterally slidably installed on the outer wall of the locking tube 6. A locking rod 8 is installed at one end of the outer moving block 9. A locking groove 10 is opened on the outer wall of the locking rod 8. An outer rotating frame 11 is rotatably installed on the outer wall of the locking tube 6. A blocking block 12 and an unlocking block 13 are installed on the outer rotating frame 11. The blocking block can press against the outer moving block 9, so that the locking rod 8 extends into the locking groove 10. The outer rotating frame 11 is rotated in the opposite direction, so that the locking rod 8 moves away from the locking groove 10.

[0023] In this embodiment, a top plate 4 is fixed to the outer end of the seedling tray 3, and a base plate 5 is fixed to the outer end of the immersion bottom cylinder 2. A clamping pipe 6 is fixedly installed on the top plate 4. A clamping rod 7 slides on the mounting plate 1, with one end passing through the base plate 5, the mounting plate 1, and the top plate 4 before extending into the clamping pipe 6 to engage and lock. This achieves the combined installation and positioning of the seedling tray 3 and the immersion bottom cylinder 2 on the mounting plate 1. After the end of the clamping rod 7 extends into the clamping pipe 6, the outer rotating frame 11 is rotated to press the sealing block 12 against the outer moving block 9. The push spring 23 drives the outer moving block 9 to slide laterally, causing the locking rod 8 to extend into the slot 10 on the outer wall of the clamping rod 7, thus achieving a firm lock between the clamping pipe 6 and the clamping rod 7. When disassembly is required, the outer rotating frame 11 is rotated in the opposite direction to activate the unlocking block 13, causing the locking rod 8 to exit the slot 10 and release the engagement, thus achieving rapid separation of the seedling tray 3 and the immersion bottom cylinder 2.

[0024] The stabilizing mechanism includes an outer fixed ring 14 and a pair of shrink blocks 15. The outer fixed ring 14 is fixedly installed on the outer wall of the clamping tube 6. The pair of shrink blocks 15 are slidably installed on the outer fixed ring 14, and the pair of shrink blocks 15 are arranged in multiple sets of rings. A pair of shrink springs 16 are installed between the pairs of shrink blocks 15. A rotating ball block 17 is installed on one end face of the outer rotating frame 11. The rotating ball block 17 passes through the pairs of shrink blocks 15 in sequence, so that the outer rotating frame 11 is stabilized and rotates on the outer wall of the clamping tube 6.

[0025] In this embodiment, when the outer rotating frame 11 rotates, the rotating ball block 17 on one end face passes sequentially between the paired shrink blocks 15 on the outer fixed ring 14. The shrinking spring 16 causes the paired shrink blocks 15 to shrink centripetally, generating clamping force and resistance on the rotating ball block 17. The rotating ball block 17 pushes the shrink blocks 15 to slide outward and then reset, forming a staged positioning feedback to ensure that the outer rotating frame 11 rotates smoothly and accurately on the outer wall of the clamping tube 6, improving the reliability of the clamping operation.

[0026] Please see Figures 1-5 As a supplementary implementation method for a bottomless rice seedling tray for rice cultivation, which includes a tray installation mechanism, a mounting clamping mechanism, and a stabilizing mechanism: a groove 18 is provided on one end face of the installation plate 1, and a block 19 is installed on one end face of the installation plate 1. The installation plate 1 is provided with multiple sets, and the groove 19 can be embedded in the groove 18 to connect adjacent installation plates 1. A connecting plate 20 is installed at the bottom end of the installation plate 1, and the installation bolt can pass through the installation plate 1 and the connecting plate 20 to fix adjacent installation plates 1. A connecting plate 21 is installed on the side wall of the clamping pipe 6, and the connecting plate 21 is fixedly installed on the top plate 4. An end block 22 is installed at one end of the clamping rod 7, and the end block 22 can contact one end face of the base plate 5. A push-in spring 23 is installed between the outer moving block 9 and the outer wall of the clamping pipe 6.

[0027] More specifically, multiple sets of mounting plates 1 are connected into an integral platform by inserting the interlocking blocks 19 into the interlocking slots 18. The mounting bolts pass through the mounting plates 1 and the connecting plates 20 to fix adjacent mounting plates 1. The seedling tray 3 and the soaking bottom cylinder 2 are placed on the mounting plate 1. The locking rod 7 slides on the mounting plate 1. After its end block 22 contacts the chassis 5, it continues to advance. The locking rod 7 passes through the chassis 5, the mounting plate 1 and the top plate 4 and extends into the locking pipe 6 on the top plate 4. The outer rotating frame 11 is rotated, and the rotating ball block 17 passes through the paired shrinking blocks 15 in sequence to provide stable feedback. The sealing block 12 presses against the outward moving block 9 so that the pushing spring 23 drives the locking rod 8 to extend into the locking slot 10 to lock. After locking, the seedling tray 3 and the soaking bottom cylinder 2 are firmly installed on the mounting plate 1 platform, and rice seedling raising operations can be carried out. When it is necessary to replace or clean, the outer rotating frame 11 is rotated in the opposite direction to make the locking rod 8 exit the locking slot 10, and the tray and bottom cylinder are quickly separated. The entire device realizes the modular installation, reliable fixation and convenient disassembly of the seedling raising equipment.

[0028] In summary, when the whole equipment is in use or running: when the tray installation mechanism is required to run, the top plate 4 is fixed to the outer end of the seedling tray 3, the bottom plate 5 is fixed to the outer end of the immersion bottom cylinder 2, the clamping pipe 6 is fixedly installed on the top plate 4, and the clamping rod 7 slides on the mounting plate 1. One end of the rod passes through the bottom plate 5, the mounting plate 1 and the top plate 4 and then extends into the clamping pipe 6 to engage, so as to realize the combined installation and positioning of the seedling tray 3 and the immersion bottom cylinder 2 on the mounting plate 1.

[0029] When the snap-fit ​​mechanism is in operation, after the end of the snap-fit ​​rod 7 extends into the snap-fit ​​tube 6, the outer rotating frame 11 is rotated to make the sealing block 12 press against the outer moving block 9. The push spring 23 drives the outer moving block 9 to slide laterally, which drives the locking rod 8 to extend into the slot 10 on the outer wall of the snap-fit ​​rod 7, thereby achieving a firm lock between the snap-fit ​​tube 6 and the snap-fit ​​rod 7. When disassembly is required, the outer rotating frame 11 is rotated in the opposite direction to make the unlocking block 13 act, and the locking rod 8 exits the slot 10 to release the snap-fit, thereby achieving a quick separation between the seedling tray 3 and the soaking bottom cylinder 2.

[0030] When the stabilizing mechanism is in operation, as the outer rotating frame 11 rotates, the rotating ball block 17 on one end face passes sequentially between the paired shrink blocks 15 on the outer fixed ring 14. The shrinking spring 16 causes the paired shrink blocks 15 to shrink centripetally, generating clamping force and resistance on the rotating ball block 17. The rotating ball block 17 pushes the shrink blocks 15 to slide outward and then reset, forming a staged positioning feedback to ensure that the outer rotating frame 11 rotates smoothly and accurately on the outer wall of the clamping tube 6, improving the reliability of the clamping operation.

[0031] Multiple sets of mounting plates 1 are connected into an integral platform by inserting the interlocking blocks 19 into the interlocking grooves 18. The mounting bolts pass through the mounting plates 1 and the connecting plates 20 to fix adjacent mounting plates 1. The seedling tray 3 and the soaking bottom cylinder 2 are placed on the mounting plate 1. The locking rod 7 slides on the mounting plate 1. After its end block 22 contacts the chassis 5, it continues to advance. The locking rod 7 passes through the chassis 5, the mounting plate 1 and the top plate 4 and extends into the locking pipe 6 on the top plate 4. The outer rotating frame 11 is rotated, and the rotating ball block 17 passes through the paired shrinking blocks 15 in sequence to provide stable feedback. The sealing block 12 presses against the outward moving block 9 so that the pushing spring 23 drives the locking rod 8 to extend into the locking groove 10 to lock. After locking, the seedling tray 3 and the soaking bottom cylinder 2 are firmly installed on the mounting plate 1 platform, and rice seedling raising operations can be carried out. When it is necessary to replace or clean, the outer rotating frame 11 is rotated in the opposite direction to make the locking rod 8 exit the locking groove 10, and the tray and bottom cylinder are quickly separated. The entire device realizes the modular installation, reliable fixing and convenient disassembly of the seedling raising equipment.
