Description

Technical Field

[0001] This invention relates to the field of ecological survey and environmental monitoring equipment technology, and in particular to a multifunctional adjustable integrated vegetation and soil sampling device for desert areas. Background Technology

[0002] Desert regions receive very little rainfall, which is irregularly distributed in time and space. Vegetation is sparse and patchy, scattered among bare land. Plant species are scarce, mainly consisting of xerophytic and halophytic shrubs, semi-shrubs, succulents, and short-lived plants. Lichens and cyanobacteria are commonly found on the surface. Desert ecosystems are characterized by low vegetation cover, large areas of exposed ground, and strong wind and sand activity. Ecological surveys often require separate vegetation quadrat surveys and soil sample collection.

[0003] Currently used survey equipment includes manual quadrats, steel tape measures, handheld GPS devices, and soil drills, which have the following main problems: the equipment is scattered and the operation process is cumbersome, resulting in low efficiency in fieldwork; the spatial correspondence between vegetation data and soil samples is not strong, affecting the accuracy of ecological process correlation analysis; traditional equipment is easily disturbed in windy and sandy environments and lacks stability; it is inconvenient to carry and cannot meet the needs of long-distance, multi-site surveys in desert areas.

[0004] Existing related patent technologies are mostly focused on single functions, such as vegetation cover measuring instruments or dedicated soil samplers, and lack integrated equipment that can simultaneously and at the same location complete vegetation observation and soil sampling.

[0031] The support block 6 is detachably installed at the bottom of the column via the support rod 5. The support block 6 has an arc-shaped structure, and four support blocks 6 form a ring structure. The ring structure is used to support and fix the second telescopic rod 7. The motor 8 is fixedly installed at the bottom end of the second telescopic rod 7, and the sampling cylinder 10 is installed on the output shaft of the motor 8. The sampling cylinder 10 is driven by the motor 8 to rotate and sample.

[0032] A laser rangefinder 14 and a high-definition camera 15 are mounted on the top of the column 1. The laser rangefinder 14 and the high-definition camera 15 are used to automatically measure the height, cover and density of plants in the sample plot.

[0033] The design has been further optimized. The bottom of column 1 is threaded with a foot 13, which is used to adjust the level of the support component.

[0034] In a further optimized design, a connecting ring 9 is provided between the motor 8 and the sampling cylinder 10. The connecting ring 9 is fixed to the output shaft of the motor 8 by locking bolts. Multiple third connecting rods 12 are fixedly connected to the connecting ring 9. The multiple third connecting rods 12 are equally spaced along the circumference of the connecting ring 9. The connecting ring 9 is connected and fixed to the sampling cylinder 10 through the third connecting rods 12.

[0035] Further optimizing the scheme, the sampling assembly also includes an expansion rod 11, which is threaded to the bottom of the connecting ring 9 and coaxially arranged inside the sampling cylinder 10. The expansion rod 11 includes a central rod body 111, multiple expansion joints 112, and multiple outer tube segments 113. The two ends of the expansion joints 112 are fixedly connected to the central rod body 111 and the outer tube segments 113, respectively, and a tension spring is provided inside the expansion joints 112. The multiple outer tube segments 113 are arranged at equal intervals along the circumferential direction, and a gap is provided between adjacent outer tube segments 113. An air bladder 114 is provided between the outer tube segments 113 and the central rod body 111. An inflation tube 115 is detachably connected to the top side wall of the central rod body 111. The air bladder 114 is inflated through the inflation tube 115 to drive the outer tube segments 113 to expand outward to compact the soil sample inside the sampling cylinder 10.

[0036] The design was further optimized by using lightweight aluminum alloy or carbon fiber materials for the support components.

[0037] To further optimize the design, a key is provided on the inner rod of the second telescopic rod 7 to prevent relative rotation between the inner rod and the outer rod.

[0038] In a further optimized design, a clamping sleeve 116 is threadedly connected to the top of the central rod 111. The clamping sleeve 116 is used to limit the movement of the external tube segment 113.

[0039] In a further optimized design, the bottom of the central rod 111 is a conical drill bit, and the top of the conical drill bit is provided with multiple limiting grooves 117.

[0042] The present invention provides a multifunctional adjustable integrated vegetation and soil sampling device for desert areas. During assembly, the uprights 1 and connecting components are first connected to form a rectangular frame. The length of the first telescopic rod 4 is adjusted and locked according to the required distance between the two uprights 1 to maintain the stability of the rectangular frame. Then, the support rod 5 and support block 6 are installed, the second telescopic rod 7 is placed in the ring formed by the support block 6, and the motor 8 and sampling cylinder 10 are installed.

[0043] During sampling, the motor 8 and the second telescopic rod 7 are started to drive the sampling cylinder 10 into the soil. After sampling is completed, the clamping sleeve 116 is rotated first to contact the limit between the clamping sleeve 116 and the outer tube 113. Then, air is injected into the air bag 114 through the inflation tube 115 to expand the outer tube 113 and compact the soil sample before extracting the sample cylinder 10. This prevents the problem of sampling being impossible due to loose soil in desert areas.

[0044] Vegetation parameters are automatically collected using a laser rangefinder 14 and a high-definition camera 15, and the data is transmitted to mobile devices via Bluetooth.
