Description

Technical Field

[0001] This utility model relates to the field of tomato planting technology, specifically to a multi-layer tomato seed germination device. Background Technology

[0002] Seed germination treatment is crucial for improving germination rate and uniformity, with soaking to soften the seed coat being a key step in the process. To maximize soaking efficiency, traditional germination devices typically use multi-layered trays to carry large quantities of tomato seeds. However, in practice, when the trays carrying the seeds are submerged, the seeds often float and scatter, causing the previously orderly arrangement to become disordered and piled up. This results in some seeds not softening completely, impacting subsequent germination efficiency.

[0003] Therefore, the existing technology has further proposed an improved scheme by adding a clamping structure. This scheme uses pressure plates on each tray to press down and fix the seeds, thereby ensuring that the seeds are difficult to float after the tray is submerged in water, thus preventing the tomato seeds from being scattered and piled up.

[0004] However, in practical applications, such clamping plates are often continuously pressed down during the seed soaking process, resulting in the seeds being covered on both sides by the plate while clamped, hindering uniform water penetration. In particular, the soaking effect is limited in the area where the clamping plate contacts the seed, creating localized soaking blind spots. Furthermore, the interlayer linkage of the clamping plates in multi-layer germination devices is poor, and the layer-by-layer operation is cumbersome, making it difficult to achieve efficiency improvements in large-scale seed processing. Utility Model Content

[0005] The purpose of this invention is to provide a multi-layer tomato seed germination device to solve the technical problem in the prior art where seeds are covered on both sides due to the continuous downward pressure of the pressure plate.

[0006] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0007] A multi-layer tomato seed germination device includes a reaction chamber and a cover. Multiple trays are longitudinally stacked inside the reaction chamber. The multiple trays are connected by a first connecting block to form a tray assembly. The first connecting block is connected to a pull rod, and the pull rod extends upward to connect with the cover.

[0008] An movable gap is provided between adjacent trays, and a clamp is provided in each tray. The clamp is slidably disposed in the movable gap. The clamp is used to clamp and release tomato seeds by sliding closer to or away from the bottom surface of the tray. Multiple clamps are connected by a second connecting block to form a clamp assembly. The second connecting block is connected to a displacement rod, which is axially slidably disposed on the hatch cover.

[0009] In a preferred embodiment of this utility model, the top of the first connecting block and the second connecting block are provided with pull rings, and the bottom of the pull rod and the displacement rod are provided with main hooks, the main hooks being movably connected to the pull rings.

[0010] As a preferred embodiment of this utility model, an auxiliary hook is provided at the middle position of the clamping plate at the top layer. The auxiliary hook is movably connected to a force-boosting rod. The force-boosting rod extends upward and is axially slidably connected to the hatch cover. The force-boosting rod is connected to the displacement rod through a connecting rod.

[0011] As a preferred embodiment of this utility model, a swivel sleeve is axially rotatably provided on the connecting rod, and a root column is connected inside the swivel sleeve by means of threaded engagement, and the root column is fixedly connected to the hatch cover.

[0012] As a preferred embodiment of this utility model, a U-shaped handle is fixedly provided on the hatch, and the U-shaped handle is located close to the first connecting block.

[0013] As a preferred embodiment of the present utility model, a support block is provided at the bottom of the second connecting block, one side of the support block is connected to the second connecting block by a reinforcing spring, and the other side of the support block abuts against the bottom surface of the tray;

[0014] The reinforcing spring extends or contracts when the displacement rod slides axially, and extends when the displacement rod drives the clamp assembly away from the bottom surface of the tray.

[0015] When the displacement rod moves the clamp assembly closer to the bottom surface of the tray, the reinforcing spring contracts.

[0016] In a preferred embodiment of this utility model, the supporting block abuts against the bottom surface of the tray via ball bearings.

[0017] As a preferred embodiment of this utility model, a redirecting plate is fixedly connected to the side of the clamping plate, the redirecting plate is fixedly connected to the first connecting block, and a notch is opened on one side of the pallet, the redirecting plate being fitted and slidably disposed within the notch.

[0018] As a preferred embodiment of this utility model, the redirecting plate is provided with a stop block, the stop block is disposed outside the notch, and the stop block slidably covers the outside of the notch.

[0019] As a preferred embodiment of this utility model, the first connecting block has a plurality of slots arranged in a longitudinal linear array, and the tray is movably inserted into the slots via the slots.

[0020] Compared with the prior art, this utility model has the following advantages:

[0021] This invention utilizes the synergistic effect of a modular clamping plate assembly and a displacement rod to provide overall constraint on the seed cluster during the immersion stage. This effectively overcomes the problem of seeds floating and scattering, ensuring that the seeds do not pile up during tray immersion and thus prevent incomplete soaking. Furthermore, the displacement rod drives the clamping plate assembly to lift vertically and synchronously, allowing one side of the seeds to detach from the clamping contact surface. This eliminates the immersion blind zone created by double-sided clamping, significantly expanding the effective immersion area. Simultaneously, the integrated moving structure of the clamping plate assembly avoids the cumbersome layer-by-layer operation of multi-layer devices. While maintaining the orderly arrangement of seeds, it achieves seamless integration of immersion positioning and dynamic adjustment processes, ensuring uniform softening of the seed coat and reducing the intensity of manual intervention through mechanized linkage.

[0029] 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.

[0030] like Figures 1 to 4 As shown, this utility model provides a multi-layer tomato seed germination device, including a reaction chamber 1 and a cover 2. The reaction chamber 1 is a rectangular container, in which a reaction solution is placed to soak tomato seeds. Multiple trays 3 are arranged longitudinally and overlappingly inside the chamber. The top of each tray 3 is open, and the sides are surrounded by a panel to prevent the seeds from escaping. The bottom plate is used to hold the tomato seeds. The multiple trays 3 are connected by a first connecting block 4 to form a tray assembly 5. The first connecting block 4 is connected to a pull rod 6, which extends upward and connects to the cover 2. An movable gap is reserved between each tray 3 to provide space for the sliding of a clamping plate 7. This sliding includes the clamping plate 7 sliding longitudinally to disengage from the bottom surface of the tray 3 and sliding laterally to move out from between the trays 3.

[0031] Each tray 3 is equipped with a clamping plate 7, which is a rectangular plate structure with a flat surface and is made of corrosion-resistant plastic or stainless steel. The clamping plate 7 is slidably positioned within the movable gap of the tray 3, and can slide up and down along the bottom surface of the tray 3 to clamp or release tomato seeds. Multiple clamping plates 7 are connected by a second connecting block 8 to form a clamping plate assembly 9. The second connecting block 8 is connected to a displacement rod 10, which is axially slidably positioned within a guide hole on the cover 2. A sealing ring is embedded in the guide hole to prevent moisture leakage.

[0032] like Figure 1 As shown, when the tray assembly 5 and the clamping plate assembly 9 are lowered into the reaction chamber 1 to soak the seeds, during the lowering phase, each clamping plate 7 is located on the bottom surface of the tray 3 to hold the seeds in place and prevent them from scattering when the seeds are submerged. When the tray 3 is submerged and in the soaking phase, the upward sliding displacement rod 10 drives the clamping plates 7 to slide upward and detach from the bottom surface of the tray 3, allowing the seeds to be fully soaked.

[0033] For ease of use, pull rings 11 are further provided on the top of both the first connecting block 4 and the second connecting block 8. The pull rings 11 are circular or elliptical metal rings. Main hooks 12 are provided at the bottom of the pull rod 6 and the displacement rod 10. The main hooks 12 have a U-shaped or J-shaped structure and are movably connected to the pull rings 11, facilitating the connection and disassembly of the tray assembly 5, the clamping plate assembly 9, and the hatch cover 2. Specifically, in actual use, the movable connection between the main hooks 12 and the pull rings 11 allows the tray assembly 5 and the clamping plate assembly 9 to be moved synchronously by the hatch cover 2, so that when the tray assembly 5 and the clamping plate assembly 9 are placed into the reaction chamber 1, the hatch cover 2 of the reaction chamber 1 is also closed simultaneously. Furthermore, the movable connection between the main hooks 12 and the pull rings 11 also facilitates the retrieval of seeds from the tray 3.

[0034] like Figure 1 and Figure 2 As shown, in order to achieve synchronous lifting and dynamic adjustment of the clamping plate assembly 9 and avoid the clamping plate assembly 9 tilting due to unilateral force, this device sets an auxiliary hook 13 in the middle of the top clamping plate 7. The auxiliary hook 13 is a small hook. The auxiliary hook 13 is connected to a force-boosting rod 14, which is axially slidably connected to the hatch cover 2. The force-boosting rod 14 is connected to the displacement rod 10 through the connecting rod 15 to form an integral structure. Thus, when the displacement rod 10 is lifted, the displacement rod 10 can lift the clamping plate assembly 9 from both sides through the auxiliary hook 13 in the middle of the clamping plate 7 and the main hook 12 on the second connecting block 8, thereby improving the overall movement balance performance. Since the lifting of the clamping plate assembly 9 is mainly to avoid long-term compression of the seed group and contact coverage of the seed ring, the displacement distance for the longitudinal lifting of the clamping plate assembly 9 does not need to be too large. The displacement form of the displacement rod 10 is given below as a specific structure:

[0035] like Figure 1 and Figure 2 As shown, a sleeve 16 is provided on the connecting rod 15. The sleeve 16 is an internally threaded metal sleeve, which is fixed to the root post 17 on the hatch cover 2 through threaded engagement. The root post 17 is a fixing screw. The rotation of the sleeve 16 drives the clamping plate assembly 9 to move up and down through the connecting rod 15, the displacement rod 10 and the force-increasing rod 14, thereby fine-tuning the height position of the clamping plate assembly 9. The threaded engagement method can fix the adjusted position, making it more convenient to use.

[0036] Since both the clamp assembly 9 and the tray assembly 5 are connected to the hatch cover 2 on one side via a rod, a U-shaped handle 18 is further fixedly installed on the hatch cover 2 to facilitate gripping and lifting of the hatch cover 2 while ensuring balanced force distribution between the internal tray assembly 5 and the clamp assembly 9. The U-shaped handle 18 is located near the first connecting block 4. During use, by simultaneously gripping the U-shaped handle 18 and the connecting rod 15, the internal tray assembly 5 and the clamp assembly 9 can be lifted and lowered more conveniently and stably. When moving up or down, the clamp 7 can abut against the outer bottom surface of the bottom plate of the tray 3 to improve the overall structure.

[0037] In practical use, a support block can be installed at the bottom of the reaction chamber 1 to support the pallet assembly 5 and the clamping plate assembly 9, or the pallet assembly 5 and the clamping plate assembly 9 can be placed directly on the bottom surface of the reaction chamber 1 for support and stress. In the connection method of suspension via hooks and pull rings 11, a support block 19 is installed at the bottom of the second connecting block 8 to add a stress point to the pallet assembly 5 on the other side. This allows the entire structure to be suspended by two points of stress (the connection between the first connecting block 4 on one side and the side of the pallet 3, and the connection between the support block 19 on the other side and the bottom surface of the pallet 3), thereby improving the stability of the overall structure.

[0038] like Figure 3 As shown, the support block 19 is a rectangular or circular block structure. One side of the support block 19 is connected to the second connecting block 8 via a reinforcing spring 20. The reinforcing spring 20 is a stainless steel helical spring. The reinforcing spring 20 extends or retracts when the displacement rod 10 slides axially. When the displacement rod 10 moves the clamping plate assembly 9 away from the bottom surface of the tray 3, the reinforcing spring 20 extends. When the displacement rod 10 moves the clamping plate assembly 9 closer to the bottom surface of the tray 3, the reinforcing spring 20 retracts. When the displacement rod 10 slides axially, it moves the clamping plate assembly 9 away from or closer to the bottom surface of the tray 3, and the reinforcing spring 20 extends and retracts. When the displacement rod 10 slides upward, it moves the reinforcing spring 20 upward through the second connecting block 8. At this time, when it moves the clamping plate assembly 9 away from the bottom surface of the tray 3, the entire structure is in the soaking solution and is in the soaking stage. When the displacement rod 10 slides downward, the reinforcing spring 20 retracts and returns to its original state. At this time, the clamping plate assembly 9 is close to the bottom surface of the tray 3 to clamp the seeds. At this time, the cover 2 can be moved upward, which can move the entire structure upward from two points.

[0039] In addition, such as Figure 3 As shown, in order to facilitate the lateral sliding of the clamping plate assembly 9 out of the pallet assembly 5, the other side of the support block 19 abuts against the bottom surface of the pallet 3 via a ball bearing 21. The ball bearing 21 is embedded in the groove at the bottom of the support block 19, reducing the sliding friction between the support block 19 and the bottom surface of the pallet 3, and further improving the smoothness of sliding.

[0040] like Figure 2 and Figure 3As shown, to reduce the thickness of the clamping plate 7, shorten the gap between adjacent pallets 3, and increase the number of pallets 3 that can be arranged in a limited space, this utility model connects the deflector plate 22, which is fixedly connected to the side of the clamping plate 7, to the first connecting block 4, instead of placing the deflector plate 22 on the top surface of the clamping plate 7, thereby reducing the thickness of the clamping plate 7. The deflector plate 22 is fixedly connected to the first connecting block 4. At the same time, a notch 23 is provided on the side panel of one side of the pallet 3, and the deflector plate 22 is fitted and slidably disposed in the notch 23 to facilitate synchronous sliding of the deflector plate 22 when the clamping plate 7 slides.

[0041] To prevent seeds from flowing out of the notch 23 when the clamping plate 7 moves upward, a stop block 24 is further provided on the redirecting plate 22. The stop block 24 is rectangular and slightly larger than the notch 23. It is fixed on the outside of the redirecting plate 22. When the redirecting plate 22 moves upward with the clamping plate 7, the stop block 24 can slide to cover the notch 23, preventing seeds from overflowing from the notch 23 during immersion.

[0042] like Figure 4 As shown, to further facilitate the loading and unloading of tomatoes, multiple longitudinally arranged trays 3 are configured as detachable structures. Multiple slots 25, rectangular grooves, are linearly arranged longitudinally on the first connecting block 4. The trays 3 are movably inserted into the slots 25 via locking blocks, which are protruding structures matching the slots 25. After insertion, slight deformation allows for fixation and disassembly. Thus, after removing the clamping plate assembly 9 from the tray assembly 5, the trays 3 can be disassembled or installed sequentially, facilitating loading and unloading.

[0043] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
