Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of community diversity, specifically to a portable shrub and grass community diversity quadrat sampling device. BACKGROUND

[0002] The richness of a biological community refers to the number of species in the community, i.e., the total number of species. The methods for determining species richness include the sampler sampling method and the quadrat method. In the quadrat method, a number of quadrats are randomly selected in the habitat of the surveyed community, the species in each quadrat are counted, and the richness of the community of this type is calculated.

[0003] Currently, when detecting the diversity of shrub and grass communities, a sampler is generally used to sample the corresponding area, and then the species in the sample are counted. The existing samplers are simply tools such as iron shovels, which directly sample the corresponding area and have the advantage of being easy to use. However, they cannot dig soil at a deep depth below the ground, so the representativeness of the extracted sample is poor. Some samplers can take soil at a deep depth, but the sample is not easy to separate from the sampler, and the soil is loose when separated, which cannot form a whole and affects the subsequent detection. Therefore, a portable shrub and grass community diversity quadrat sampling device is proposed to solve the above problems. SUMMARY

[0004] The utility model aims at providing a portable shrub and grass community diversity quadrat sampling device to solve the problems in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0006] As an optional solution of the portable shrub and grass community diversity quadrat sampling device, the device comprises a base, wheels, and a fixed plate.

[0007] The bottom of the base is fixedly connected with wheels for walking.

[0008] The top of the base is fixedly connected with the fixed plate, one side of the fixed plate is fixedly connected with an inclined plate, and the other end of the inclined plate is fixedly connected with a handle.

[0009] One side of the fixed plate is fixedly connected with a lifting mechanism, and one side of the lifting mechanism is fixedly connected with a sampling mechanism.

[0010] The sampling mechanism comprises a moving block, a mounting frame and a second motor, one side of the moving block is fixedly connected with the lifting mechanism, the bottom of the moving block is fixedly connected with the mounting frame, the inside of the mounting frame is fixedly connected with the second motor, the main shaft tail of the second motor is fixedly connected with a rotating shaft, and the bottom of the rotating shaft is fixedly connected with a sampling cylinder.

[0011] As an optional solution of the portable shrub-grass community diversity quadrat sampling device, the bottom of the sampling cylinder is unevenly arranged.

[0012] As an optional solution of the portable shrub-grass community diversity quadrat sampling device, the bottom of the moving block is fixedly connected with a hydraulic rod, the free end of the hydraulic rod is fixedly connected with a moving plate, the bottom of the moving plate is rotatably connected with a rotating disc, the bottom of the rotating disc is fixedly connected with a connecting column, the bottom of the connecting column is fixedly connected with extrusion plates, and the inside of the moving plate is rotatably connected with the rotating shaft.

[0013] As an optional solution of the portable shrub-grass community diversity quadrat sampling device, the outside of the connecting column is slidably connected with the sampling cylinder.

[0014] At present, when the shrub-grass community diversity is detected, a sampler is generally used to sample the corresponding area, and then the types in the sample are calculated. The existing sampler is simply a tool such as a shovel, which directly samples the corresponding area and has the advantage of convenient use, but cannot dig the soil below the ground, so that the representativeness of the extracted sample is poor. Some samplers can take deep soil, but the sample is not easy to separate from the sampler, and the soil is loose when separated, cannot form a whole, and affects the subsequent detection. When in use, the device is moved to the corresponding position by connecting an external power supply, the sampling mechanism is moved by starting the lifting mechanism, the rotating shaft is rotated by the second motor, and the sampling cylinder is rotated by the rotating shaft. At this time, the soil can be sampled in depth, and the moving plate moves by the hydraulic rod. At this time, the moving plate drives the rotating disc, the connecting column and the extrusion plate to move downward, so as to extrude the soil in the sampling cylinder, ensure that it moves downward as a whole, and ensure the integrity of the sample.

[0015] As an optional solution of the portable shrub-grass community diversity quadrat sampling device, the lifting mechanism comprises a guide frame, a first motor and a threaded shaft, the outside of the guide frame is fixedly connected with the fixed plate, the top of the guide frame is fixedly connected with the first motor, the main shaft tail of the first motor is fixedly connected with the threaded shaft, the outside of the threaded shaft is spirally connected with a threaded sleeve, the outside of the threaded sleeve is fixedly connected with a sliding block, and the outside of the sliding block is fixedly connected with the sampling mechanism.

[0016] As an optional scheme of the portable grass community diversity quadrat sampling device, the outer side of the sliding block is in sliding connection with the guide frame.

[0017] By starting the first motor to drive the threaded shaft to rotate, the threaded shaft drives the threaded sleeve to move, so as to drive the sliding block to move, and then drive the sampling mechanism to move up and down, facilitating subsequent sampling.

[0018] Compared with the prior art, the utility model has the advantages that:

[0019] In use, the device is moved to the corresponding position, the sampling mechanism is moved by starting the lifting mechanism, the rotating shaft is rotated by the second motor, the sampling cylinder is rotated by the rotating shaft, the soil can be sampled at a depth at this time, the moving plate is moved by the hydraulic rod at this time, the moving plate drives the rotating disc, the connecting column and the extrusion plate to move downward, the soil in the sampling cylinder is extruded, the soil is ensured to move downward as a whole, and the integrity of the sample is ensured.

[0020] When the sampling cylinder rotates, the connecting column will rotate with the sampling cylinder, the sampling cylinder is ensured to rotate normally, and the bottom of the sampling cylinder is unevenly arranged, so that the sample can be stably segmented and sampled.
