Description

Technical Field

[0001] This utility model relates to the technical field, specifically to an experimental device for placing seeds on the ground. Background Technology

[0002] In plant research, it is necessary to explore the influence of animals on the seed fate of plants in their natural habitats from the perspective of the mutualistic relationship between plants and animals, especially the influence of frugivores on seeds.

[0003] In existing technologies, a combination of ground placement and infrared cameras is generally used to study the selection of different types of seeds (whole aggregate fruit, intact seed, naked seed with seed coat removed) by ground-based fruit predators (rodents, ants), as well as the differences in their handling and consumption of different types of seeds.

[0004] Conventional experimental methods typically involve covering the petri dish with a protective cover. Existing devices often integrate the protective cover, base, and petri dish into a single unit. To adjust the size of the protective cover's aperture, custom-made covers are required for replacement. This makes it impossible to flexibly choose a protective cover with a suitable aperture size based on experimental needs, and the internal space of the protective cover is fixed.

[0005] In summary, existing seed placement experimental devices require protective covers of different aperture sizes and volumes, which reduces the applicability of the device and the efficiency of experimental operations. Utility Model Content

[0006] The purpose of this invention is to provide a seed placement experiment device to solve the technical problem in the prior art that the size of the protective cover's aperture and the size of the internal space cannot be adjusted in a timely manner according to the actual situation.

[0007] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution: A seed placement experimental apparatus includes: a petri dish for holding experimental seeds; a base for supporting the petri dish, wherein multiple through holes are vertically arranged along the edge of the base, and nails are driven through the through holes and into the soil to fix the base to the soil surface; an inner mesh cover made of rigid material, which covers the base and is connected to the base; and an outer mesh cover made of flexible material, which can be wrapped around the side wall of the inner mesh cover and is detachably connected to the inner mesh cover.

[0008] Furthermore, the inner mesh cover is a cylindrical metal structure with an open bottom, and an annular support is provided at the bottom of the inner mesh cover, which is magnetically connected to the base.

[0009] Furthermore, the inner mesh cover has at least two positioning rods arranged vertically from top to bottom on its sidewall. The outer mesh cover is wound around and fixed to the inner mesh cover by suspending the mesh openings at the start and end positions of the outer mesh cover as it is wound around the inner mesh cover.

[0010] Furthermore, the base is equipped with a detachable insect-proof platform at its bottom to raise the distance between the bottom of the base and the soil surface, thus preventing ants from climbing onto the base.

[0011] Furthermore, the bottom of the base has a threaded groove, and the top of the insect-proof platform is provided with a threaded joint that can be threadedly connected to the threaded groove.

[0012] Furthermore, the sidewalls of the insect-proof platform are provided with an adhesive layer and are covered with release paper.

[0013] Furthermore, the inner mesh cover has a pore size of 20-35mm to prevent birds from contacting the seeds located in the petri dish.

[0014] Furthermore, the outer mesh cover has a pore size of 5-10 mm to prevent rodents from contacting the seeds located in the culture dish.

[0015] Compared with the prior art, this utility model has the following advantages: The seed placement experimental device provided in this utility model features a composite protective cover structure consisting of an inner mesh cover and an outer mesh cover. The inner mesh cover serves as the base, and outer mesh covers with different aperture sizes are wrapped around the inner mesh cover. The aperture size of the outer mesh cover is used as the aperture size of the entire protective cover to achieve the experimental purpose of distinguishing different animals from those contacting the seeds. If the size of the protective cover needs to be changed, only the size of the inner mesh cover needs to be changed. This is achieved by wrapping the outer mesh cover around the inner mesh cover to accommodate the changed size of the outer mesh cover, eliminating the need to order a custom outer mesh cover and simplifying the number of accessories required for the experiment.

[0016] Furthermore, the petri dishes are placed on the base and secured by nails that penetrate the base and are driven into the soil, providing reliable support for the base and ensuring that the base supporting the petri dishes is always stably fixed in the preset experimental position, avoiding positional deviation of the experimental samples due to device movement.

[0020] 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.

[0021] like Figure 1 As shown, this utility model provides a seed placement experiment device, which mainly consists of a composite protective cover structure of an inner mesh cover 3 and an outer mesh cover 4, which is placed on a container 1. The inner mesh cover 3 serves as the base, and the outer mesh cover 4 with different pore sizes is wrapped around the inner mesh cover 3. The pore size of the outer mesh cover 4 is used as the pore size of the entire protective cover to achieve the experimental purpose of distinguishing different animals from those that come into contact with the seeds.

[0022] Among them, container 1 serves as the direct container for the experimental seeds and is made of transparent material, such as highly transparent plastic or glass. Depending on the experimental requirements, container 1 can be selected with different depth specifications to meet the needs of different seed types, such as larger beans and smaller herb seeds. At the same time, its smooth inner wall facilitates cleaning and reuse after the experiment.

[0023] The vessel 1 is placed on the base 2, which is the core of the support and fixation of the entire device. Its main body is flat, and the central area is a groove or flat surface that matches the vessel 1 to ensure that the vessel 1 does not easily slide after being placed. There are 3-4 vertical through holes 21 evenly distributed around the edge.

[0024] In use, the metal nail body 22 is driven through the through hole 21 and vertically into the soil to a depth of about 5-10cm. The base 2 is firmly fixed to the ground by the mechanical interlocking action of the nail body 22 and the soil.

[0025] This multi-point fixing design can effectively resist external forces such as wind, rain, or small animals touching the device, preventing the entire device from shifting or tipping over and ensuring the stability of the experimental position.

[0026] The inner mesh cover 3 serves as the basic support structure of the protective cover. It is made of rigid materials, such as galvanized iron wire mesh or rigid plastic grid, and has a stable three-dimensional shape. Its overall structure is a "cover" structure with a closed top and an open bottom, and the side walls and top are integrally formed mesh structures.

[0027] The inner mesh cover 3 covers the base 2 and wraps around the container 1. The inner mesh cover 3 is detachably connected to the base 2. The bottom edge of the inner mesh cover 3 is equipped with a detachable connection structure, such as elastic buckles and flange slots, which are adapted to the eaves of the base 2: when it is necessary to cover, the bottom of the mesh cover is aligned with the eaves of the container 1 and fixed by buckle or slot; when it is necessary to change the seeds, the buckles can be easily pried open to separate them quickly, making the operation convenient.

[0028] The rigid material gives the inner mesh cover 3 sufficient structural strength, which can not only support the winding and fixing of the outer mesh cover 4, but also prevent the protective cover from collapsing due to external pressure, thus protecting the seeds in the container 1 from mechanical damage.

[0029] The outer mesh cover 4 is the core adjustment component for the protective function. It is made of flexible materials, such as nylon mesh and polyester yarn mesh, which are lightweight and have a certain degree of extensibility.

[0030] The outer mesh cover 4 can be made from filter screens of different pore sizes available on the market, depending on the experimental requirements, and cut to match the size of the inner mesh cover 3.

[0031] The outer mesh cover 4 is flexible in its use: it can be wrapped around the side wall of the inner mesh cover 3 and, if necessary, cover the top. The flexible material can be used to completely wrap the mesh structure of the inner mesh cover 3, so that the actual protective aperture of the entire protective cover is determined by the outer mesh cover 4.

[0032] The outer mesh cover 4 has Velcro or straps on its edges. After wrapping, it can be fixed by sticking or binding to ensure a tight fit with the inner mesh cover 3 without any protective gaps.

[0033] When the protection level needs to be changed, the outer mesh cover 4 can be removed simply by unfastening the fixing structure and a new mesh cover with the corresponding aperture can be replaced; if the size of the inner mesh cover 3 is adjusted, the outer mesh cover 4 can be adapted to the new size by cutting the filter screen, without the need for additional customization, which significantly improves the versatility of the device.

[0034] Regarding the detachable arrangement between the inner mesh cover 3 and the base 2, this embodiment provides the following examples.

[0035] As shown in the figure, the inner mesh cover 3 adopts a cylindrical metal structure with an open bottom. The whole is made of high-strength rust-resistant metal, such as 304 stainless steel. It serves as the supporting base for the outer mesh cover 4 and has structural stability and weather resistance.

[0036] The cylindrical shape of the inner mesh cover 3 is adapted to the circular outline of the vessel 1, and its diameter is slightly larger than the outer diameter of the vessel 1. A ring-shaped support 31 is welded to the bottom edge of the inner mesh cover 3. The support is made of the same metal material and is perpendicular to the cylindrical side wall of the inner mesh cover 3, forming a ring-shaped base 2.

[0037] The lower surface of the ring bracket 31 is embedded with strong magnetic blocks, such as neodymium iron boron magnets, evenly distributed along the circumference, in the form of 3-4 blocks. Correspondingly, the upper surface of the base 2 is embedded with a suitable iron sheet or magnetic metal sheet in the area that contacts the ring bracket 31.

[0038] When the inner mesh cover 3 covers the vessel 1, the annular support 31 is in contact with the surface of the base 2. The inner mesh cover 3 and the base 2 are quickly magnetically connected by the adsorption of the magnetic block and the iron sheet, which not only ensures the connection is stable, but also simplifies the disassembly and assembly operation.

[0039] Regarding the detachable nature of the outer mesh cover 4 and the inner mesh cover 3, this embodiment provides the following examples.

[0040] The inner mesh cover 3 has at least two positioning rods 32, preferably three, arranged vertically from top to bottom on its side wall. These rods are located at the top, middle, and bottom positions, respectively. The positioning rods 32 are fixed to the side wall of the inner mesh cover 3 by welding, forming outwardly protruding suspension fulcrums.

[0041] Furthermore, the positioning rod 32 is inclined upwards, with a length of 5-10mm and a diameter of 2-5mm.

[0042] When the outer mesh cover 4 is wound, it is precisely fixed by the positioning rod 32: First, align the starting end of the outer mesh cover 4, such as the mesh hole at the edge, with the positioning rod 32 below, put the mesh hole into the positioning rod 32 and tighten it slightly as the starting point of the winding; then, tightly wrap the outer mesh cover 4 along the circumferential direction of the side wall of the inner mesh cover 3. When the winding reaches the end, align the mesh hole at the end of the outer mesh cover 4 with the corresponding positioning rod 32 and put it in to fix it.

[0043] The starting and ending positions of the outer mesh cover 4 are firmly fixed, which can prevent loosening or slippage caused by wind or external force after wrapping, and ensure that it fits tightly with the side wall of the inner mesh cover 3 without any protective gaps.

[0044] This connection method eliminates the need for additional straps or Velcro; fixation is achieved solely through the mechanical engagement of the mesh and positioning rod 32. This simplifies the operation process and avoids interference with the protective effect from additional fasteners, such as straps or Velcro that may obscure part of the mesh.

[0045] To meet the experimental requirements, the following embodiments are also provided in this implementation plan.

[0046] like Figure 2 As shown, the bottom of the base 2 is provided with a detachable insect-proof platform 5 to raise the distance between the bottom of the base 2 and the soil surface, so as to prevent ants from climbing onto the base 2.

[0047] Specifically, the insect-proof platform 5, as a detachable anti-ant component of the base 2, is made of hard and corrosion-resistant materials, such as ABS engineering plastic and anti-corrosion resin. It is cylindrical or polygonal in shape and designed to be 3-5cm high. This height can effectively raise the vertical distance between the bottom of the base 2 and the soil surface, using the physical height difference that ants cannot cross to block their path to climb directly up the base 2 along the soil; at the same time, it will not cause the center of gravity of the base 2 to shift upward due to excessive height, thus avoiding affecting the overall stability of the device.

[0048] Furthermore, the bottom of the base 2 is provided with a threaded groove 51, and the top of the insect-proof platform 5 is provided with a threaded joint 52 that can be threadedly connected to the threaded groove 51, so as to realize quick assembly and disassembly between the base 2 and the insect-proof platform 5.

[0049] Furthermore, the sidewall of the insect-proof platform 5 is provided with an adhesive layer and is covered with release paper.

[0050] Specifically, when not in use, the release paper can isolate impurities such as dust and soil particles, preventing the adhesive from becoming contaminated with dirt beforehand and thus reducing its stickiness. This ensures that the adhesive can maintain optimal stickiness when the release paper is torn off after assembly.

[0051] When in use, simply peel off the release paper along the side wall of the platform to expose the adhesive layer. If any ants attempt to climb the side wall of the platform, they will be firmly stuck to the adhesive and unable to move upwards to the base 2, forming a dual anti-ant barrier of physical elevation and adhesive interception, which greatly improves the reliability of anti-ant protection.

[0052] If the adhesive becomes covered with ants or impurities, weakening its stickiness, the adhesive layer can be peeled off and replaced with a new release paper-covered adhesive, or the entire platform can be replaced.

[0053] In this embodiment, the following examples are given regarding the aperture of the inner mesh cover 3 and the outer mesh cover 4, based on specific experimental requirements.

[0054] The inner mesh cover 3 has a pore size of 20-35mm to prevent birds from contacting the seeds located in the container 1; the outer mesh cover 4 has a pore size of 5-10mm to prevent rodents from contacting the seeds located in the container 1.

[0055] Specifically, the usage methods are as follows, depending on the different experimental subjects; 1) Fully open treatment: nail the base into the soil so that the edge of the petri dish is flush with the soil and there is no obstruction; birds, rodents and other mammals can eat the seeds.

[0056] 2) Rodent feeding treatment: Set up an insect-proof platform with the base nailed 3cm above the soil. Remove the release paper of the adhesive layer on the insect-proof platform to ensure that invertebrates (such as ants) cannot enter the petri dish.

[0057] An inner mesh cover with a 35mm aperture is placed over the petri dish. Only small rodents can pass through the mesh of the inner mesh to feed or carry seeds, while other vertebrates (such as birds) cannot enter.

[0058] 3) Ant feeding treatment: Nail the base into the soil so that the edge of the petri dish is flush with the soil. Cover the petri dish with an inner mesh cover with a 35mm aperture, and wrap and fix an outer mesh cover with a 15mm aperture to the inner mesh cover. The bottoms of the outer mesh cover and the inner mesh cover are flush, so that only ants can enter the metal mesh cover to feed or carry seeds, while other vertebrates cannot enter.

[0059] 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.
