Description

Technical Field

[0001] This utility model relates to the field of plant resource field sampling technology, and in particular to a field plant cutting sampler. Background Technology

[0002] When surveying wild plant resources, propagation is often necessary. Cuttings are a common asexual propagation technique. Rapid propagation by cuttings effectively preserves the superior characteristics of the mother plant while enabling rapid and large-scale reproduction in a short period. Therefore, rapid propagation by cuttings is frequently used when propagating wild plant resources to facilitate further research.

[0003] However, when propagating some plants, especially those that are difficult to root, through cuttings, it is often necessary to quickly immerse the cuttings in water or rooting solution to prevent them from drying out and dying. While timely watering of cuttings is relatively easy to perform in the laboratory, it is difficult to implement in the field.

[0004] In particular, when transporting cuttings of wild plant resources, it is best to soak them in water or rooting solution promptly to ensure a high survival rate. However, when wild plant cuttings are soaked in liquid, bumps or sudden braking during long-distance transport can cause the liquid to splash out. Therefore, splash prevention is a key design consideration in the design of field plant samplers.

[0005] Currently, there is no specialized sampler for long-distance transport of wild plant cuttings, making it impossible to efficiently collect wild plant cuttings, promptly soak, hydrate, and effectively preserve them, or effectively transport soaked cuttings. Ultimately, this makes it difficult to implement rapid propagation of wild plant resources through cuttings, resulting in a low survival rate.

[0006] Based on the above-mentioned technical problems, this utility model provides a sampler for wild plant cuttings. Utility Model Content

[0007] The purpose of this invention is to provide a field plant cutting sampler to solve the problems existing in the prior art.

[0008] To achieve the above objectives, this utility model provides the following solution: This utility model provides a field plant cutting sampler, comprising:

[0009] The inner cylinder has several vertical holes at its bottom and is filled with cultivation soil.

[0010] An outer cylinder is fitted over the inner cylinder, and a gap is provided between the outer wall of the inner cylinder and the inner wall of the outer cylinder. The top surface of the inner cylinder is higher than the top surface of the outer cylinder.

[0011] An annular partition, wherein several groups of annular partitions are provided, and the several groups of annular partitions are fixed at equal intervals between the inner cylinder and the outer cylinder, and a filling space is formed between adjacent partitions. The filling space is filled with water-retaining material, and through holes are arrayed on the partitions.

[0012] A closed ring is rotatably connected to the top surface of the outer cylinder, rotatably connected to the inner cylinder, and rotatably connected to the annular partition at the top surface. The closed ring is provided with water-permeable holes, which are arranged corresponding to the through holes.

[0013] An interval adjustment assembly is installed on the top edge of the inner cylinder, and the interval adjustment assembly is used to adjust the distance between the top of the inner cylinder and the top of the outer cylinder;

[0014] The cross-sectional shape of both the annular partition and the closed ring is arc-shaped.

[0015] According to the field plant cutting sampler provided by this utility model, cotton absorbent strips are fixed in the vertical holes respectively.

[0016] According to the field plant cutting sampler provided by this utility model, a sealing ring is provided between the closed ring and the inner wall of the inner cylinder.

[0017] According to the field plant cutting sampler provided by this utility model, the top surface of the inner cylinder is detachably connected to a sealing cover, the sealing cover has an insertion hole, and the sealing cover is positioned with the top edge of the inner cylinder by screws.

[0018] According to the field plant cutting sampler provided by this utility model, the interval adjustment component includes an adjustment screw, and there are not less than three sets of adjustment screws. The adjustment screws are vertically threaded to the top edge of the inner cylinder, and the adjustment screws are rotatably connected to the top edge of the outer cylinder.

[0020] According to the field plant cutting sampler provided by this utility model, the inner cylinder has a diameter of 7cm-8cm and a height of 15cm-20cm; the outer cylinder has a diameter of 10cm-12cm.

[0021] The present invention discloses the following technical effects:

[0022] 1) The annular partition divides the space between the inner and outer cylinders into multiple filling spaces, which are filled with water-retaining material to store a large amount of water. Through the through holes on the annular partition and the permeable holes on the closed ring, water can be effectively replenished and slowly released, providing a stable water environment for the cuttings, reducing the adverse effects of water fluctuations on plant growth, and improving the survival rate of the cuttings.

[0023] 2) The closed ring can rotate, which changes the correspondence between the permeable holes and the through holes on the annular baffle, thereby controlling the amount of water replenishment. When a large amount of water needs to be replenished, the permeable holes and through holes are aligned perfectly; when a smaller amount of water needs to be replenished, the closed ring can be rotated to partially align or offset the permeable holes and through holes, achieving precise control over water replenishment.

[0024] 3) The design of the interval adjustment component allows the sampler to adjust the distance between the top of the inner cylinder and the top of the outer cylinder according to plant growth or environmental changes. This function helps improve the growth environment of plant roots, such as regulating air circulation, controlling moisture and temperature around the roots, and promoting healthy plant growth.

[0025] 4) Both the annular baffle and the closed ring have arc-shaped cross-sections. This design not only increases the stability of the structure, but may also facilitate the uniform distribution and flow of moisture to a certain extent, thus improving the overall performance of the sampler.

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0027] Figure 1 This is a schematic diagram of the structure of the field plant cutting sampler of this utility model.

[0028] The components include: 1. Inner cylinder; 2. Outer cylinder; 3. Annular partition; 4. Water storage material; 5. Sealing ring; 6. Cotton absorbent strip; and 7. Adjusting screw. Detailed Implementation

[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] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figure 1 This utility model provides a field plant cutting sampler, comprising:

[0032] Inner cylinder 1, with several vertical holes at the bottom, and filled with cultivation soil;

[0033] Outer cylinder 2 is fitted outside inner cylinder 1, and there is a gap between the outer wall of inner cylinder 1 and the inner wall of outer cylinder 2. The top surface of inner cylinder 1 is higher than the top surface of outer cylinder 2.

[0034] Annular partition 3, several sets of annular partition 3 are provided, and several sets of annular partition 3 are fixed at equal intervals between the inner cylinder 1 and the outer cylinder 2. A filling space is formed between adjacent partitions, and water storage material 4 is filled in the filling space. Through holes are arrayed on the partition.

[0035] The closed ring 5 is rotatably connected to the top surface of the outer cylinder 2. The closed ring 5 is rotatably connected to the inner cylinder 1 and to the annular partition 3 on the top surface. Water permeable holes are provided on the closed ring 5, and the water permeable holes are arranged corresponding to the through holes.

[0036] An interval adjustment assembly is installed on the top edge of the inner cylinder 1 and is used to adjust the distance between the top of the inner cylinder 1 and the top of the outer cylinder 2.

[0037] Among them, the cross-sectional shape of the annular partition 3 and the closed ring 5 is an arc structure.

[0038] In use, cuttings of wild plants are inserted into the cultivation soil filled in the inner cylinder 1. Because there is a gap between the outer wall of the inner cylinder 1 and the inner wall of the outer cylinder 2, and this gap is divided into multiple filling spaces by several sets of equally spaced and fixed annular partitions 3, these filling spaces are filled with water-retaining material 4. Simultaneously, a sealing ring 5 is rotatably connected to the top surface of the outer cylinder 2, the inner cylinder 1, and the topmost annular partition 3. The sealing ring 5 has permeable holes, initially corresponding to the through holes on the annular partition 3.

[0039] When the plants need water, water can be added to the interstitial areas (i.e., the areas filled with water-storing material 4) through the top of the outer cylinder 2 (since the top surface of the inner cylinder 1 is higher than the top surface of the outer cylinder 2, there is space at the top of the outer cylinder 2 for operation). The water will enter each filled space through the through holes on the annular partition 3 and the permeable holes on the closed ring 5, and will be absorbed and stored by the water-storing material 4.

[0040] As the water in the growing soil is consumed, the water in the water storage material 4 will gradually permeate into the growing soil through the through holes on the annular partition 3 and several through holes at the bottom of the inner cylinder 1, providing a continuous water supply for the plants.

[0041] When it is necessary to adjust the distance between the top of the inner cylinder 1 and the top of the outer cylinder 2 according to the plant growth or environmental factors, the interval adjustment component is operated. This component is installed on the top edge of the inner cylinder 1. Through its adjustment function, the distance between the top of the inner cylinder 1 and the top of the outer cylinder 2 can be changed, thereby affecting the spatial state between the inner cylinder 1 and the outer cylinder 2 (such as air circulation, the degree of contact between the water storage material 4 and the outside world, etc.) to meet the needs of different growth stages of plants.

[0042] The design was further optimized by fixing cotton absorbent strips 6 inside the vertical holes.

[0043] When water is added to the space between the inner cylinder 1 and the outer cylinder 2, the water is absorbed by the water-retaining material 4. One end of the cotton absorbent strip 6 is immersed in the water-retaining material 4, while the other end is in contact with the growing soil inside the inner cylinder 1. Due to the excellent water absorption and retention properties of the cotton material, the moisture in the water-retaining material 4 is slowly and continuously transferred to the growing soil through the cotton absorbent strip 6, providing moisture for the cuttings. As the moisture in the growing soil is depleted, the cotton absorbent strip 6 continuously draws moisture from the water-retaining material 4 to replenish it, maintaining a relatively stable soil moisture level.

[0044] The cotton absorbent strip 6 should be made of pure cotton. Pure cotton fibers are highly absorbent, soft, and non-toxic to plants, and will not damage plant roots. Its thickness and length should be reasonably selected according to the interval between the inner cylinder 1 and the outer cylinder 2 and the size of the through hole to ensure that the absorbent strip can fully contact the water storage material 4 and the cultivation soil, while not being too thick and clogging the through hole.

[0045] The cotton absorbent strip 6 can be fixed inside the through hole using glue. The glue should be environmentally friendly, non-toxic, strong, and able to maintain its adhesion for a long time to ensure the absorbent strip does not fall off during use. When fixing, pay attention to the position and direction of the absorbent strip to ensure it can effectively transfer moisture.

[0046] The design was further optimized by installing a sealing ring between the closed ring 5 and the inner wall of the inner cylinder 1.

[0047] When the closed ring 5 is rotated to adjust the correspondence between the permeable holes and the through holes on the annular partition 3, or when water is being supplied to the plants normally, the sealing ring plays a sealing role to prevent water from leaking out from the gap between the closed ring 5 and the inner wall of the inner cylinder 1, ensuring that water can enter the filling space or the cultivation soil according to the designed path, thereby improving the efficiency of water use.

[0048] The sealing ring should be made of rubber, which has good elasticity and sealing properties, and can adapt to the minute gap changes between the sealing ring 5 and the inner wall of the inner cylinder 1 to ensure the sealing effect. At the same time, the rubber material should be resistant to aging and corrosion to adapt to complex outdoor environmental conditions.

[0049] The sealing ring can be installed between the sealing ring 5 and the inner wall of the inner cylinder 1 using an interference fit. During installation, ensure that the sealing ring is flat and free from twisting to guarantee sealing performance. Applying a suitable amount of lubricant to the installation area of ​​the sealing ring can facilitate installation and reduce wear.

[0050] The design is further optimized by adding a detachable cover to the top surface of the inner cylinder 1. The cover has an insertion hole and is positioned with screws between it and the top edge of the inner cylinder 1.

[0051] When inserting the cuttings into the potting soil in inner cylinder 1, first open the sealed cover, insert the cutting into the appropriate position, then close the sealed cover and secure it to the top edge of inner cylinder 1 using screws. The size of the insertion hole should be slightly larger than the diameter of the cutting to ensure smooth insertion while minimizing water and soil loss. The sealed cover protects the cuttings and prevents external debris from entering inner cylinder 1. The screw-locking mechanism facilitates disassembly and installation, allowing for easy observation and pruning of the plant.

[0052] The sealing cap can be made of plastic, which is lightweight, low-cost, corrosion-resistant, and easy to process into various shapes. The edges of the insertion hole should be smoothed to avoid damaging the cuttings. Screws should be made of stainless steel, which has good corrosion resistance and strength, ensuring a stable connection over long-term use.

[0053] The contact surface between the sealing cap and the top edge of the inner cylinder 1 should be designed with positioning structures, such as protrusions and grooves, to facilitate quick positioning and installation. The position and size of the screw holes should be designed reasonably to ensure that the screws can be tightly connected without damaging the sealing cap and the inner cylinder 1. A sealing gasket can be placed on the contact surface between the sealing cap and the top edge of the inner cylinder 1 to further improve the sealing performance and prevent moisture and soil leakage.

[0054] The scheme is further optimized. The interval adjustment component includes an adjustment screw 7. There are no fewer than three sets of adjustment screws 7. The adjustment screws 7 are vertically threadedly connected to the top edge of the inner cylinder 1. The adjustment screws 7 are rotatably connected to the top edge of the outer cylinder 2.

[0055] When it is necessary to adjust the distance between the top of the inner cylinder 1 and the top of the outer cylinder 2, the adjusting screw 7 is rotated. Since the adjusting screw 7 is threadedly connected to the top edge of the inner cylinder 1 and rotatably connected to the top edge of the outer cylinder 2, rotating the adjusting screw 7 will cause the inner cylinder 1 to move in the vertical direction, thereby changing the distance between the top of the inner cylinder 1 and the top of the outer cylinder 2. Setting no less than three sets of adjusting screws 7 can ensure the stability during the adjustment process, so that the inner cylinder 1 can be evenly stressed and avoid tilting or shaking.

[0056] The adjusting screw 7 should be made of high-strength steel to ensure it can withstand the forces during adjustment and maintain stability over long-term use. The steel surface should be treated with anti-corrosion measures, such as galvanizing or spraying with anti-corrosion paint, to prevent rusting and corrosion in outdoor environments.

[0057] The threaded connection between the adjusting screw 7 and the top edge of the inner cylinder 1 should be designed with a self-locking function to prevent the inner cylinder 1 from shifting due to its own weight or other external forces after adjustment. A scale marking can be provided on the adjusting screw 7 for precise control of the distance between the top of the inner cylinder 1 and the top of the outer cylinder 2. Simultaneously, the rotating connection between the adjusting screw 7 and the top edge of the outer cylinder 2 should use a bearing or bushing structure to reduce friction during rotation and make the adjustment operation easier.

[0058] Further optimization of the design involves setting scale lines on the outer wall of the outer cylinder 2 and the outer wall of the inner cylinder 1.

[0059] Further optimization of the design: the inner cylinder 1 has a diameter of 7cm-8cm and a height of 15cm-20cm; the outer cylinder 2 has a diameter of 10cm-12cm.
