Description

Technical Field

[0001] This utility model relates to the field of seedling sowing technology, and in particular to a simple integrated device for wheat sowing and seedling cultivation in the laboratory. Background Technology

[0002] The laboratory wheat sowing and seedling raising device achieves repeatable and quantifiable management of the entire process from seed to standardized seedlings by controlling plant spacing, row spacing, sowing depth, and microenvironmental factors such as substrate moisture, nutrients, temperature, and light. It can rapidly sow and simultaneously raise hundreds of samples at once, completely replacing the errors caused by inconsistent depth, density, and uneven emergence resulting from manual sowing. This ensures that research in genetic transformation, mutant screening, and physiological stress experiments obtains consistent starting materials, significantly reducing experimental errors and improving data reliability. Its modular tray and detachable sowing head design support arbitrary density switching from 24 to 384 wells, and is compatible with conventional petri dishes, tissue culture bottles, and hydroponic boxes, achieving seamless "sowing-raising-transfer" and reducing root damage caused by frequent transfers before the three-leaf stage, saving 30% of costs. The device reduces labor and time costs; its built-in transparent humidity hood and adjustable LED light source allow researchers to observe early events such as coleoptile elongation and primary root development in real time without opening the chamber. Combined with image recognition software, it can obtain phenotypic parameters such as germination potential, emergence rate, root length, and leaf area in high throughput, providing big data support for QTL localization and phenotypic verification after gene editing. At the same time, the device uses sterile-grade materials and a closed ventilation structure to minimize the risk of soil-borne pathogens and cross-contamination, ensuring the safe propagation of transgenic or precious mutant materials. This promotes the development of wheat functional genomics, molecular breeding, and stress biology research towards higher throughput, higher precision, and lower cost, and has important practical significance and broad promotion value for accelerating the breeding of new varieties and ensuring food security.

[0003] Currently, when conducting wheat breeding experiments in the laboratory, the common method for placing seeds one by one into the grid of the seedling tray using manual tweezers or a simple spoon is to use a simple wheat sowing and seedling raising device. Due to the small size of the seeds and the high reproducibility of the operation, operators are prone to errors such as over-counting, under-counting, or uneven distribution, resulting in differences in the number of seeds in the same batch of seedling trays. This not only reduces the comparability and reliability of the experimental data but also consumes a lot of manpower and time. Therefore, it is necessary to improve the existing device technology. Utility Model Content

[0004] The purpose of this invention is to provide a simple integrated device for wheat sowing and seedling raising in the laboratory, in order to solve the problem mentioned in the background art that the existing devices use manual tweezers or simple spoons to place the seeds one by one into the grid of the seedling tray. Because the seeds are small and the operation is highly repetitive, the operator is very likely to make mistakes such as too many, missing, or unevenly distributed seeds, resulting in differences in the number of seeds in the same batch of seedling trays.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A simple laboratory-grade wheat sowing and seedling raising device, comprising:

[0007] Seedling components;

[0008] A seeding component is disposed above a seedling component;

[0009] The seeding assembly includes a seeding tray with several seed-receiving holes through its upper wall. A rotating disk is fitted to and rotatably mounted on the inner bottom wall of the seeding tray. The rotating disk has several feeding holes of the same number, position, and size as the seed-receiving holes. A limiting ring is fitted to the bottom wall of the rotating disk and is fixedly installed on the inner wall of the seeding tray. A hollow groove is formed on the outer wall of the seeding tray, and a lever is provided inside the hollow groove. One end of the lever is fixedly connected to the outer wall of the rotating disk. A seed-dispensing guide tube is fixedly connected below the feeding holes.

[0010] Preferably, the upper wall of the seeding tray is provided with a first mounting hole and a second mounting hole. A first iron block is fixedly installed inside the first mounting hole, and a second iron block is fixedly installed inside the second mounting hole. The upper wall of the rotating disk is provided with a third mounting hole, and a magnetic block is fixedly installed inside the third mounting hole. The first iron block and the second iron block are both connected to the magnetic block by magnetic attraction.

[0011] Preferably, the first iron block, the second iron block, and the magnetic block are all the same size.

[0012] Preferably, the seedling assembly includes a holding cylinder, with two symmetrically and fixedly connected support rods on the inner wall of the holding cylinder. A seed placement plate is fixedly connected between the two support rods. An installation groove is provided on the upper wall of the seed placement plate, and a mesh plate is fixedly installed inside the installation groove. The mesh plate is positioned below several seed guide tubes.

[0013] Preferably, the container is made of transparent glass material, and the outer wall of the container is fixedly provided with scale lines.

[0014] Preferably, the upper wall of the container has two symmetrically formed slots, and the outer wall of the seed tray has two symmetrically and fixedly connected insert rods, which are inserted into and matched with the slots.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] This invention features a seed-dispensing tray and a rotating disc forming a "double-layer perforated plate" structure. Initially, the seed-containing hole and the feeding hole are misaligned, and the openings are sealed. A large number of seeds can be poured in, and by shaking, each hole can be precisely positioned to hold one seed, achieving "single-seed quantitative distribution" and avoiding omissions. Subsequently, the handle is turned to rotate the rotating disc at a certain angle, and the two holes instantly overlap. Under the action of gravity, the seeds fall directly into the corresponding grid position through the feeding hole and the seed-dispensing guide tube, completing one synchronous seeding operation. This ensures that the number of seeds in each grid is consistent and improves the comparability of experiments. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] Example:

[0024] Please see Figures 1-4As shown, this utility model is a simple integrated device for wheat sowing and seedling cultivation in a laboratory, comprising:

[0025] Seedling components;

[0026] A seeding component is disposed above a seedling component;

[0027] The seeding assembly includes a seeding tray 1, with several seed receiving holes 2 extending through the upper wall of the seeding tray 1. A rotating disk 3 is fitted and rotatably mounted on the inner bottom wall of the seeding tray 1. Several feeding holes 4, the number, position, and size of which are the same as those of the seed receiving holes 2, are opened on the rotating disk 3. A limiting ring 5 is fitted and fixedly installed on the inner wall of the seeding tray 1. A hollow groove 6 is opened on the outer wall of the seeding tray 1. A toggle handle 7 is provided inside the hollow groove 6, and one end of the toggle handle 7 is fixedly connected to the outer wall of the rotating disk 3. A seeding guide tube 18 is fixedly connected below the feeding holes 4.

[0028] Specifically, in the initial state, the seed receiving hole 2 on the seeding tray 1 and the feeding hole 4 on the rotating disk 3 are staggered. Furthermore, a storage box is placed below the seeding component. Personnel can pour multiple seeds onto the seeding tray 1 and fill the seed receiving hole 2 by flattening or shaking it. Each seed receiving hole 2 can only hold one seed. After the seed is filled, the excess seeds are moved to the seed storage box below for recycling.

[0029] As can be seen from the above, the seeding tray 1 and the rotating disk 3 form a "double-layer perforated plate" structure: initially, the magnetic block 10 attracts the first iron block 8, the seed receiving hole 2 and the feeding hole 4 are misaligned, and the opening is closed, so that a large number of seeds can be poured in and shaken so that each hole can be exactly framed with one seed, realizing "single seed quantitative" and avoiding missing the count; then, the handle 7 drives the rotating disk 3 to rotate at a certain angle, the magnetic block 10 attracts the second iron block 9, the two holes instantly overlap, and the seeds fall directly into the corresponding grid position of the grid plate 14 through the feeding hole 4 → seeding guide tube 18 under the action of gravity, completing one synchronous seeding, ensuring that the number of seeds in each grid is consistent and improving the comparability of the experiment.

[0030] Depend on Figure 4 It is known that, in order to strengthen the connection between the seeding tray 1 and the rotating disk 3, the upper wall of the seeding tray 1 is provided with a first mounting hole and a second mounting hole. A first iron block 8 is fixedly installed inside the first mounting hole, and a second iron block 9 is fixedly installed inside the second mounting hole. The upper wall of the rotating disk 3 is provided with a third mounting hole, and a magnetic block 10 is fixedly installed inside the third mounting hole. The first iron block 8 and the second iron block 9 are both connected to the magnetic block 10 by magnetic adsorption.

[0031] The first iron block 8, the second iron block 9, and the magnetic block 10 are all the same size.

[0032] In the initial state, the first iron block 8 and the magnetic block 10 are connected by magnetic attraction. At this time, the seed receiving hole 2 on the seeding tray 1 and the feeding hole 4 on the rotating disk 3 are staggered to facilitate filling the seed receiving hole 2 with seeds. After the seeds are filled, the staff uses the lever 7 to rotate the rotating disk 3, so that the second iron block 9 and the magnetic block 10 are connected by magnetic attraction. At this time, the seed receiving hole 2 on the seeding tray 1 and the feeding hole 4 on the rotating disk 3 are aligned. The seeds enter the seedling component through the feeding hole 4 and the seeding guide tube 18.

[0033] As can be seen from the above, magnetic adsorption provides a clear "positioning feel" and self-locking force, preventing the rotating disk 3 from shifting on its own during shaking; the first iron block 8, the second iron block 9 and the magnetic block 10 are the same size, ensuring that the area of ​​the adsorption surface is consistent, so that the switching between misalignment and overlap only requires a small amount of force, making the operation labor-saving and can be completed with one hand, which meets the needs of high frequency and small batch seeding in the laboratory.

[0034] Depend on Figure 3 It is known that the seedling raising component includes a holding cylinder 11, and two support rods 12 are symmetrically and fixedly connected to the inner wall of the holding cylinder 11. A seed placement plate 13 is fixedly connected between the two support rods 12. An installation groove is opened on the upper wall of the seed placement plate 13. A mesh plate 14 is fixedly installed inside the installation groove. The mesh plate 14 is set below several seed guide tubes 18.

[0035] The container 11 is made of transparent glass material, and scale lines 15 are fixedly provided on the outer wall of the container 11.

[0036] As can be seen from the above, the transparent glass container 11 can be pre-filled with treatment solutions such as salt stress, drought or nutrient difference, and the scale line 15 facilitates precise control of the liquid level; each grid of the grid plate 14 is directly opposite the outlet of the seed-planting tube 18, and after the seed falls, the root system can vertically pass through the mesh and extend into the liquid, realizing the integrated docking of "top-planting and bottom-cultivation", avoiding secondary transfer damage. At the same time, the glass wall allows for direct observation of root length and root hair changes, which is suitable for continuous recording of stress experiments such as salt stress.

[0037] Depend on Figure 2 It can be seen that two slots 16 are symmetrically opened on the upper wall of the container 11, and two plug rods 17 are symmetrically and fixedly connected to the outer wall of the seed tray 1. The plug rods 17 are inserted and matched with the slots 16.

[0038] As can be seen from the above, the insertion rod 17 and the slot 16 form a quick insertion and removal interface. After the inoculation is completed, the inoculation component can be separated by lifting it upwards. The container 11 is left independently on the workbench, which is convenient for placing into the incubator or climate chamber. The insertion length is ≥15mm, which ensures that the overall positioning is reliable during the inoculation process and will not cause misalignment between the guide tube opening and the grid plate 14 due to shaking, further ensuring the accuracy of inoculation and the consistency of the experiment.

[0039] The accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
