Description

Technical Field

[0001] This utility model belongs to the field of sampling device technology, and in particular relates to a plant sample sampling device. Background Technology

[0002] In botanical research, whether it is research on plant taxonomy, physiology, genetics, or ecology, it is necessary to obtain plant samples. In plant taxonomy, researchers need to collect various parts of the plant, such as roots, stems, leaves, flowers, and fruits, to observe their morphological characteristics and determine the plant species. For plant physiology research, it is necessary to collect plant samples from specific growth stages and specific parts to analyze changes in their internal chemical composition and physiological indicators. In genetic research, in order to analyze the genetic composition and genetic diversity of plants, it is necessary to collect samples from a large number of plant individuals.

[0003] However, existing plant sample collection devices may cause excessive pulling, squeezing or tearing of leaves during the collection process, thereby damaging the leaf tissue structure. Damaged leaf samples may also cause changes in the internal chemical composition of the plant, affecting the accurate analysis of nutrients, secondary metabolites and other substances in the leaves. Utility Model Content

[0004] The purpose of this invention is to provide a plant sample sampling device. By setting a shearing mechanism, it solves the problem that existing plant sample sampling devices may cause excessive pulling, squeezing or tearing of leaves during the collection process, thereby damaging the tissue structure of the leaves. Damaged leaf samples may also cause changes in the internal chemical composition of the plant, affecting the accurate analysis of nutrients, secondary metabolites and other substances in the leaves.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a plant sample collection device, including a support rod, on which a shearing mechanism and a collection mechanism are provided;

[0007] A gasket is fixedly connected to the outer wall of the support rod. The shearing mechanism includes a shearing assembly one and a shearing assembly two. The shearing assembly one includes a support plate fixedly connected to the right side of the support rod. Two connecting rods one are hinged to the top of the support plate. Shearing heads are fixedly connected to the sides of the two connecting rods one that are close to each other. Connecting rods two are hinged to the left sides of the two connecting rods one.

[0008] Furthermore, the second shearing assembly includes a threaded rod rotatably connected to the inner wall of the right side of the support rod, the left side of the threaded rod rotatably extending to the outside of the support rod, and a movable block threadedly connected to the outer wall of the threaded rod.

[0009] Furthermore, limit grooves are provided on the inner walls of the front and rear sides of the support rod, and limit blocks are slidably connected to the inner walls of the two limit grooves. The sides of the two limit blocks that are close to each other are fixedly connected to the moving block.

[0010] Furthermore, a C-shaped connecting rod is fixedly connected to the right side of the movable block, and the right side of the C-shaped connecting rod extends slidably to the outside of the support rod. The C-shaped connecting rod is hinged to the two connecting rods, and a handle is fixedly connected to the left extension of the threaded rod.

[0011] Furthermore, the collecting mechanism includes two connecting blocks rotatably connected to the outer wall of the support rod, and each of the two connecting blocks has a rotating groove on its inner wall.

[0012] Furthermore, two retaining rings are fixedly connected to the outer wall of the support rod, and the outer walls of the two retaining rings slide into the two rotating grooves respectively. A rectangular support plate is fixedly connected to the bottom of the two connecting blocks.

[0013] Furthermore, two triangular support blocks are fixedly connected to the top and bottom of the rectangular support plate, a collection box is fixedly connected to the right side of the rectangular support plate, and the right sides of several triangular support blocks are fixedly connected to the collection box.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up a shearing mechanism, when sampling is required, the handle can be turned, which drives the threaded rod to rotate. When the threaded rod rotates, it will cooperate with the limiting groove and the limiting block, thereby driving the moving block to move to the right. When the moving block moves to the right, it will push the C-shaped connecting rod to move to the right. Thus, the two connecting rods 2 drive the shearing heads on the two connecting rods 1 to move closer to each other, completing the shearing of the sample. This allows for precise control of the speed and force of the shearing heads moving closer to each other based on factors such as the size and texture of the plant sample, ensuring successful sampling and reducing the risk of hand injury during the shearing process, thus ensuring personal safety.

[0016] 2. By setting up a collection mechanism, the sheared sample will fall into the collection box. Since the connecting block is rotatably connected to the support rod through a rotating groove and a retaining ring, the collection box, under the connection of the rectangular support plate and the triangular support block, and under the action of gravity, keeps the opening facing upward. This ensures that the sample can enter the collection box smoothly, preventing the sample from scattering into the surrounding environment due to improper opening direction of the collection box, reducing the possibility of sample loss, improving sampling efficiency, and eliminating the need to constantly monitor and adjust the opening direction of the collection box during operation, thus improving the convenience and smoothness of operation.

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.

[0027] Please see Figure 1-5As shown, this utility model is a plant sample sampling device, including a support rod 1. A shearing mechanism 2 and a collection mechanism 3 are mounted on the support rod 1. A gasket 101 is fixedly connected to the outer wall of the support rod 1. The shearing mechanism 2 includes a shearing component 21 and a shearing component 22. The shearing component 21 includes a support plate 211 fixedly connected to the right side of the support rod 1. Two connecting rods 212 are hinged to the top of the support plate 211. Shearing blades 213 are fixedly connected to the sides of the two connecting rods 212 that are close to each other. Connecting rods 214 are hinged to the left sides of the two connecting rods 212. The shearing component 22 includes a threaded rod 221 rotatably connected to the inner wall of the right side of the support rod 1. The left side of the threaded rod 221 rotatably extends outside the support rod 1. A sliding contact is threaded onto the outer wall of the threaded rod 221. The moving block 222 and the support rod 1 have limit grooves 223 on their front and rear inner walls. Limit blocks 224 are slidably connected to the inner walls of the two limit grooves 223. The sides of the two limit blocks 224 that are close to each other are fixedly connected to the moving block 222. A C-shaped connecting rod 225 is fixedly connected to the right side of the moving block 222. The right side of the C-shaped connecting rod 225 extends slidably to the outside of the support rod 1. The C-shaped connecting rod 225 is hinged to the two connecting rods 214. A handle 226 is fixedly connected to the left extension of the threaded rod 221. By setting the shearing mechanism 2, the speed and force of the shearing blades 213 approaching each other can be precisely controlled according to the size, texture and other factors of the plant sample, ensuring that the sampling can be completed smoothly and reducing the risk of hand injury during the shearing process, thus ensuring personal safety.

[0028] The collection mechanism 3 includes two connecting blocks 301 rotatably connected to the outer wall of the support rod 1. Each connecting block 301 has a rotating groove 302 on its inner wall. Two retaining rings 303 are fixedly connected to the outer wall of the support rod 1, and their outer walls slide into the two rotating grooves 302. A rectangular support plate 304 is fixedly connected to the bottom of the two connecting blocks 301. Two triangular support blocks 305 are fixedly connected to the top and bottom of the rectangular support plate 304. A collection box 306 is fixedly connected to the right side of the rectangular support plate 304. The right sides of several triangular support blocks 305 are also fixedly connected to the collection box 306. By setting up the collection mechanism 3, the sample can be smoothly entered into the collection box 306, preventing the sample from scattering into the surrounding environment due to improper opening direction of the collection box 306, reducing the possibility of sample loss, improving sampling efficiency, and eliminating the need to constantly monitor and adjust the opening direction of the collection box 306 during operation, thus improving the convenience and smoothness of operation.

[0029] A specific application of this embodiment is as follows: During use, hold the pad 101, align the right side of the support rod 1 with the sample to be sampled, and position the required cutting point between the two cutting blades 213. Turn the handle 226, which drives the threaded rod 221 to rotate. As the threaded rod 221 rotates, it engages with the limiting groove 223 and the limiting block 224, thereby moving the moving block 222 to the right. When the moving block 222 moves to the right, it pushes the U-shaped connecting rod 225 to the right. This causes the cutting blades 213 on the two connecting rods 212 to move closer together via the two connecting rods 214, completing the cutting of the sample. This allows for precise control of the speed and force at which the cutting blades 213 approach each other based on factors such as the size and texture of the plant sample, ensuring successful cutting. Sampling is performed efficiently, reducing the risk of hand injury during the cutting process and ensuring personal safety. The cut sample falls into the collection box 306. Since the connecting block 301 is rotatably connected to the support rod 1 through the rotating groove 302 and the retaining ring 303, the collection box 306, connected by the rectangular support plate 304 and the triangular support block 305, and under the action of gravity, keeps the opening facing upwards. This ensures that the sample can smoothly enter the collection box 306, preventing the sample from scattering into the surrounding environment due to improper opening direction of the collection box 306, reducing the possibility of sample loss, improving sampling efficiency, and eliminating the need to constantly monitor and adjust the opening direction of the collection box 306 during operation, thus improving the convenience and smoothness of operation. After completing the above operations, the sample in the collection box 306 can be taken out.
