Description

Technical Field

[0001] The utility model belongs to the technical field of biomass investigation, and in particular relates to a forest biomass investigation device. Background Art

[0002] Biomass refers to the total amount of organic matter accumulated by an organism or community over a certain period of time, usually expressed as the dry mass accumulated per unit area and per unit time. The study of biomass usually involves collecting forest litter to calculate the change in ecosystem biomass. Litter is a metabolite produced by plants in nature during their growth and development. It is produced by the above-ground parts of plants and falls to the ground. It serves as a source of material and energy for decomposers, thereby maintaining the continuous and stable functions of forest ecosystems. Forest litter is a key process in the nutrient cycle of terrestrial ecosystems, and the accurate collection of litter is a key process in calculating the change in biomass.

[0003] At present, when collecting litter in the forest, the connecting rod is fixed to a three-dimensional bracket by screws, and then the net bag is placed on the three-dimensional bracket. The installation is cumbersome and labor-intensive. Therefore, we propose a forest biomass survey device to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the problem that when collecting fallen leaves in the forest, the connecting rod is fixed to a three-dimensional bracket by screws, and then the net bag is placed on the three-dimensional bracket, which is complicated and labor-intensive to install.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] A forest biomass survey device comprises a frame, a fixed rod and a net bag respectively arranged at the lower end and the upper end of the frame, the fixed rod being provided with a conical tip away from the frame, and a fixed plate being fixedly installed on the fixed rod near the conical tip, the frame comprising four I-shaped wheels and four transfer rods, a first rotating ring and a second rotating ring being fixedly installed at both ends of the four transfer rods, the four transfer rods being rotatably installed on the four I-shaped wheels through the first rotating ring and the second rotating ring, and the first rotating ring and the second rotating ring of adjacent transfer rods being rotatably installed on the same I-shaped wheel, the lower ends of the four I-shaped wheels being provided with insertion holes, the upper ends of the fixed rods being fixedly installed with an insertion rod, and the insertion rod being movably inserted into the insertion hole.

[0007] It is further defined that the I-shaped wheel is provided with a mounting hole, and the mounting hole is provided with an internal thread, the mounting hole is connected with a locking bolt through the internal thread, and the lower end of the locking bolt abuts against the first rotating ring. With such a structural design, when the locking bolt penetrates deeply into the mounting hole, it can generate a squeezing force on the first rotating ring, so that the first rotating ring and the second rotating ring fit closely together, thereby keeping the frame in a set shape.

[0008] It is further defined that a plurality of positioning hooks are fixedly mounted on the upper end of the transfer rod, and the plurality of positioning hooks pass through the meshes of the net bag. With such a structural design, the plurality of positioning hooks can position the net bag to fix the net bag, and the net bag is applicable to net bags of different sizes.

[0009] It is further defined that a non-slip rubber layer is attached to the side where the first rotating ring and the second rotating ring are close to each other. With such a structural design, the non-slip rubber layer can increase the friction between the first rotating ring and the second rotating ring to prevent the frame from being deformed when subjected to external force.

[0010] It is further defined that a clamping block is fixedly mounted on the inner wall of the jack, and an L-shaped clamping slot matching the clamping block is provided on the plug rod. With such a structural design, the clamping block matches the L-shaped clamping slot, and the fixing rod can be clamped under the I-shaped wheel, and it is convenient for disassembly and assembly.

[0011] The utility model adopting the above technical solution has the following advantages:

[0012] The utility model positions the net bag by means of the frame and the fixing rod. After the fixing rod is inserted into the ground and the transfer rod is rotated to put the frame in an unfolded state, the frame can be placed on the fixing rod to form a bracket to support the net bag. The structure is relatively simple and more convenient to assemble and disassemble. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present utility model will be described in detail below in conjunction with the drawings and specific embodiments. It should be noted that in the drawings or the description of the specification, similar or identical parts are all denoted by the same drawing number, and the implementation manners not shown or described in the drawings are the forms known to those of ordinary skill in the art. In addition, the directional terms mentioned in the embodiments, such as "upper", "lower", "top", "bottom", "left", "right", "front", "rear", etc., are only the directions referring to the drawings and are not used to limit the protection scope of the present utility model.

[0027] As Figures 1 to 5 shown, a forest biomass survey device of the present utility model includes a frame body 1, a fixed rod 2 and a mesh bag 3 respectively arranged at the lower end and the upper end of the frame body 1. The fixed rod 2 is provided with a tapered tip 21 at the part away from the frame body 1, and a fixed disk 22 is fixedly installed on the fixed rod 2 near the tapered tip 21. The frame body 1 includes four spools 11 and four adapter rods 12. The two ends of the four adapter rods 12 are respectively fixedly installed with a first rotating ring 121 and a second rotating ring 122. The four adapter rods 12 are rotationally installed on the four spools 11 through the first rotating ring 121 and the second rotating ring 122, and the first rotating ring 121 and the second rotating ring 122 of the adjacent adapter rods 12 are rotationally installed on the same spool 11. The lower ends of the four spools 11 are provided with jacks 111. The upper end of the fixed rod 2 is fixedly installed with a plug rod 23, and the plug rod 23 is movably inserted into the jack 111. The sides of the first rotating ring 121 and the second rotating ring 122 close to each other are attached with anti-slip rubber layers.

[0028] The spool 11 is provided with a mounting hole, and the mounting hole is provided with internal threads. A locking bolt 4 is threadedly connected in the mounting hole. The lower end of the locking bolt 4 abuts against the first rotating ring 121. When the locking bolt 4 rotates in the mounting hole and is close to the first rotating ring 121, a force will be generated on the first rotating ring 121, so that the first rotating ring 121 and the second rotating ring 122 are closely attached.

[0029] A number of positioning hooks 5 are fixedly installed at the upper end of the adapter rod 12. The number of positioning hooks 5 pass through the mesh holes of the mesh bag 3. The positioning hooks 5 passing through the mesh holes can have a positioning effect on the mesh bag 3 and are applicable to mesh bags 3 of different sizes.

[0030] A clamping block 112 is fixedly installed on the inner wall of the jack 111. An L-shaped clamping groove 231 adapted to the clamping block 112 is formed on the insertion rod 23. After the clamping block 112 is snapped into the L-shaped clamping groove 231, a clamping effect can be exerted on the insertion rod 23 to lock the fixed rod 2 and prevent the fixed rod 2 from detaching from the frame body 1.

[0031] The usage method of the present utility model is as follows:

[0032] During use, rotate the adapter rod 12 on the winding drum 11 to make adjacent adapter rods 12 perpendicular to each other, thereby expanding the frame body 1 into a square frame. At this time, turn the locking bolt 4, and the first rotating ring 121 and the second rotating ring 122 in the winding drum 11 are closely attached under pressure. The locking bolt 4 locks the mutual connection points of the adapter rods 12 to prevent the shape of the frame body 1 from changing under external force;

[0033] Hold the fixed rod 2 by hand and insert the insertion rod 23 of the fixed rod 2 into the jack 111. When the clamping block 112 penetrates into the L-shaped clamping groove 231 and abuts against the groove wall of the L-shaped clamping groove 231, rotate the fixed rod 2 to make the clamping block 112 snap into the L-shaped clamping groove 231, so that the fixed rod 2 is clamped with the winding drum 11 to complete the assembly of the bracket;

[0034] Pierce the conical tip 21 of each fixed rod 2 into the soil until the lower end of the fixed disk 22 contacts the ground to firmly fix the bracket composed of the frame body 1 and the fixed rod 2 on the ground. Then place the mesh bag 3 on the frame body 1. The positioning hooks 5 can have a positioning effect on the mesh bag 3. The mesh bag 3 located inside the frame body 1 can collect the forest litter, which is convenient for completing the subsequent investigation work on forest biomass.

[0035] The above has introduced in detail a forest biomass investigation device provided by the present utility model. The description of the specific embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
