Description

Technical Field

[0001] The invention relates to the technical field of pulling out pole-diameter plants and collecting soil, and in particular to a single-row pulling out and synchronously clearing soil acquisition device and method for soil remediation sampling. Background Art

[0002] Soil remediation refers to the process of treating contaminated soil by physical, chemical or biological means to reduce or eliminate harmful substances in the soil and restore the productivity and ecological environmental functions of the soil. During the soil remediation process, soil collection is required to obtain soil information to provide basic data for subsequent pollution assessment, remediation plan design and effect evaluation. To obtain soil from some large-diameter plants, it is necessary to pull out the plants and collect soil information from their roots. Large-diameter plants are those with obvious upright stems. The stems of these plants are usually thicker and can support taller plants, such as sugarcane.

[0003] After the pole-diameter plants (such as sugarcane) are planted and mature, they need to be pulled out of the ground. Most of them are pulled out manually, which has low work efficiency. There are some problems with pulling out by equipment. After the pole-diameter plants are pulled out, a lot of soil will be attached to the roots, which is also an indispensable carrier of soil information for soil remediation. At the same time, the pulled-out pole-diameter plants need to be cleared manually, which increases the work intensity. The clamping and pulling out of the pole-diameter plants are independent actions and cannot be performed synchronously, which adds unnecessary equipment movement and reduces work efficiency. For this reason, we propose a single-row pulling and synchronous soil clearing acquisition device and method for soil remediation sampling. Summary of the invention

The method for obtaining soil remediation samples by single-row pull-out synchronous soil clearing according to claim 8, characterized in that: The steps include: S1: Connect the movable shafts (105) at both ends of the stabilizing support arm (104) to an external mobile body, move the mobile body to the farmland, move the two sets of clamping plates (204) to the two sides of the stem-diameter plants to be pulled out, start the stepping motor (212), drive the transmission gear (209) to rotate, so that the linkage rack (208) moves towards each other in the waist-shaped frame (207), drive the guide clamping plates (204) to move closer to each other, and drive the clamping plates (204) to clamp the rows of stem-diameter plants; S2: When the stepper motor (212) is started, the reel is driven to rotate, the pull rope (213) is driven to retract, and the lifting plate (210) is pulled vertically upward along the direction of the rectangular frame (211), and the two groups of clamping plates (204) are driven to move upward. At this time, the two groups of guide frames (203) move upward on the movable base plate (202) to pull out the clamped stem-diameter plant; S3: The driving motor (306) is started, and the gear transmission box (307) drives the linkage belt (308) to drive the toothed roller (310) to rotate, driving the toothed plate (311) to push the shovel plate (312) to move obliquely downward along the concave frame (302), and at the same time of the pulling operation, the soil on both sides of the root of the stem-diameter plant is separated and loosened; S4: The driving motor (306) drives the convex toothed belt (304) to rotate at the same time. When the convex toothed belt (304) rotates, the rotating convex toothed belt (304) is close to the roots of the pole-diameter plants, and cooperates with the arc-shaped scraper (305) to clean and remove the mud adhering to the roots of the pole-diameter plants; S5: The electric telescopic assembly (106) is started synchronously, driving the collecting frame (103) to extend into the soil cleaning assembly (300) to collect the soil scraped by the arc scraper (305), thereby realizing the sampling operation.
