Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of carbon reserve measurement, and in particular relates to a carbon reserve measurement device and a test method for spray-seeding slope soil. Background Art
[0002] Carbon storage refers to the amount of carbon retained in an ecosystem, which is closely related to the existing amount of organisms in the ecosystem. It is an important environmental parameter. By measuring the carbon storage in the soil of the sprayed slope, the carbon sequestration capacity of the sprayed slope can be effectively evaluated, which is conducive to the subsequent ecological restoration of the sprayed plants on the slope.
[0003] The existing spray-seeding slope soil carbon storage measurement device cannot fix and support the sampling mechanism well during sampling. During the sampling process, the soil around the sampling will collapse to a certain extent, affecting the sampling effect. After the sampling tube is pulled out of the soil, the soil adhered to the outer wall of the sampling tube will fall into the soil sample and pollute the soil sample, affecting the measurement accuracy of soil carbon storage. In addition, the soil sample in the sampling tube will adhere to the inner wall of the sampling tube, and the sampled sample cannot be completely collected, which will also reduce the measurement accuracy. Therefore, how to overcome the above-mentioned technical problems and defects has become a key issue that needs to be solved. Summary of the invention
[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a device and a method for measuring the carbon reserve of a spray-seeding slope soil.
[0005] The object of the present invention is achieved in that: A device for measuring carbon reserves in soil of a spray-seeding slope comprises a sampling mechanism, wherein the sampling mechanism comprises a supporting assembly, a sampling barrel, a lifting assembly and a cleaning assembly for cleaning the outer wall of the sampling barrel; the supporting assembly comprises a base, threaded drill rods are screwed at the four corners of the upper surface of the base, an inverted triangular drill bit is integrally connected to the lower end of the threaded drill rod, inverted triangular protrusions are evenly fixedly connected to the lower surface of the base, and a through hole for the sampling barrel to pass through is arranged in the middle of the upper surface of the base; the lifting assembly is fixedly connected to the upper left and right sides of the sampling barrel, and the lifting assembly comprises symmetrically fixedly connected to the upper left and right sides of the sampling barrel A support plate, the upper surface of the support plate is connected to a first screw through a first bearing seat, the first screw is screwed to a support rod, and the support rod is provided with a first screw hole matching the first screw; the upper and lower ends of the sampling barrel are both opened, an electric push rod is installed in the middle of the lower surface of the support rod, the telescopic end of the electric push rod is fixedly connected to a circular pressure plate, the outer circumference of the circular pressure plate is evenly fixedly connected to a first brush, and the other end of the first brush is in contact with the inner wall of the sampling barrel; the cleaning component is symmetrically arranged on the left and right sides of the sampling barrel, and the cleaning component is symmetrically fixed to the left and right sides of the upper surface of the base.
[0006] Furthermore, the cleaning component includes columns symmetrically fixedly connected to the left and right sides of the upper surface of the base, and a second screw is screwed on the column. The end of the second screw close to the sampling barrel is connected to a clamping block through a second bearing seat, and a second brush is evenly fixedly connected to the side of the clamping block close to the sampling barrel. The other end of the second brush is in contact with the outer wall of the sampling barrel. The soil adhered to the outer wall of the sampling barrel is brushed off by the second brush to prevent the soil from falling into the soil sample and contaminating the soil sample, thereby improving the measurement accuracy of soil carbon reserves.
[0007] Furthermore, the clamping block is a semicircular arc structure, and the sampling tube can be completely clamped by two semicircular arc structure clamping blocks. The soil adhering to the outer wall of the sampling tube can be completely scraped off by the second brush fixed to the clamping block, without cleaning dead corners, thereby further improving the measurement accuracy.
[0008] Furthermore, the column is provided with a second screw hole matching the second screw rod.
[0009] Furthermore, the first brush and the second brush are both soft brushes, so as to avoid the first brush and the second brush from damaging the inner and outer walls of the sampling tube.
[0010] Furthermore, threaded holes matching the threaded drill rods are arranged at the four corners of the upper surface of the base.
[0011] The present invention also discloses a method for testing carbon storage in spray-seeding slope soil, comprising the following steps: (1) Sampling was carried out using the above-mentioned spraying slope soil carbon storage measurement device. The specific sampling steps are as follows: (1.1) Place the base in the soil area where sampling is required on the spraying slope. Insert the inverted triangle protrusion on the lower surface of the base into the soil. Rotate the threaded drill rod to insert the inverted triangle drill bit deep into the soil to fix and support the base. (1.2) Rotate the two first screws to lower the sampling tube into the soil. When the sampling tube reaches the specified depth, stop rotating the first screw, and then rotate the second screw to move the clamping block toward the sampling tube until the second brush abuts against the outer wall of the sampling tube. (1.3) Rotate the two first screws to raise the sampling tube. During the rising process of the sampling tube, the second brush will brush off the soil adhering to the outer wall of the sampling tube. When the sampling tube rises to a height where the lower surface is higher than the upper surface of the clamping block, the soil adhering to the outer wall of the sampling tube is completely scraped off, and the rotation of the first screw is stopped; (1.4) Place the sample collection box directly below the sampling tube, turn on the electric push rod, and extend the electric push rod to move the circular pressing plate and the first brush downward. The circular pressing plate squeezes the soil sample in the sampling tube to discharge it from the sampling tube into the sample collection box. The first brush scrapes the soil sample adhering to the inner wall of the sampling tube and drops it into the sample collection box, thus completing the sampling; (2) Use the carbon storage calculation device to calculate the carbon storage of the soil sample in step (1.4).

The device for measuring carbon reserves in slope soil by spraying of the present invention comprises a supporting mechanism including a base, and inverted triangular protrusions are evenly fixedly connected to the lower surface of the base. When sampling, the inverted triangular protrusions are inserted into the soil. The arrangement of the inverted triangular protrusions can increase the contact area between the base and the soil and improve the fixed support effect. The inverted triangular drill bit is inserted into the soil to a certain depth through a threaded drill rod to further improve the fixed support effect.
[0014] 3. The device for measuring carbon reserves in the soil of the spray-seeding slope of the present invention can completely brush off the soil adhering to the outer wall of the sampling tube through the cleaning component, thereby preventing the soil from falling into the soil sample and causing contamination to the soil sample, thereby improving the measurement accuracy of the soil carbon reserves.
[0015] 4. The device for measuring carbon reserves in the soil of the spray-seeding slope of the present invention can completely discharge the soil sample in the sampling tube from the sampling tube to the sample collection box through the electric push rod, the circular pressure plate and the first brush. The sample collection is completely conducive to the subsequent measurement of soil carbon reserves and improves the measurement accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
