Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to a sampling device used for salinized soil analysis experiments. Background Art

[0002] Salinized soil refers to the process in which salt in the bottom soil layer or groundwater rises to the surface with capillary water and accumulates in the surface soil after the water evaporates. This phenomenon is also called salinization. Since the laws of water and salt movement in different types of saline soils under different climatic conditions in different regions are different, it is necessary to actually detect and analyze the salinized soil.

[0003] For example, a sampling device for salinized soil analysis experiments disclosed in Chinese patent CN206248366U has a simple and fast sampling operation, which is easy and labor-saving and can be completed by one person. It can not only ensure the integrity of the soil sample, but also ensure the original state of the soil; after the sampling is completed, there is no soil in the sampling tube, and the sampling process will not cause cross contamination. In addition, the sampling device is easy to disassemble and clean, which ensures the accuracy of the soil sample, has good implementation effect, and is suitable for large-scale promotion and application.

[0004] Although this structure can be used to sample soil, in order to ensure the integrity of soil sampling, when the sampling tube is lifted up, part of the soil will be fractured, resulting in poor integrity of the sampled soil. Therefore, we propose a sampling device for salinized soil analysis experiments that can completely remove the sampled soil, facilitate accurate understanding of the salinity content of each layer of the soil, and improve the accuracy of analytical data in the analysis experiment. Utility Model Content

[0005] The utility model aims to provide a sampling device for salinized soil analysis experiments to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sampling device for salinized soil analysis experiments, comprising a sampling barrel, a handle fixedly mounted on the outer wall of the sampling barrel, and a processing component arranged outside the handle, the processing component comprising a cutting component arranged outside the sampling barrel, and a cleaning component arranged outside the cutting component.

[0007] Preferably, the cutting assembly includes a mounting plate fixedly mounted on the top surface of the sampling barrel, a motor is fixedly mounted on the outer wall of the mounting plate, a rotating rod is fixedly mounted on the output end of the motor, a first bevel gear is fixedly mounted on the outer wall of the rotating rod, the first bevel gear is meshed with a second bevel gear, a first cutting ring is fixedly mounted on the side wall of the second bevel gear, a third bevel gear is meshed on the side of the first bevel gear away from the second bevel gear, a second cutting ring is fixedly mounted on the side wall of the third bevel gear, a protective barrel is arranged on the outside of the third bevel gear, a fixing plate is fixedly mounted on the bottom of the sampling barrel, and a cutter is fixedly mounted on the outer wall of the second cutting ring.

[0008] Preferably, the cleaning assembly includes a counterweight block slidably arranged inside the sampling barrel, a first cleaning ring is fixedly installed on the bottom of the counterweight block, a fixed block is fixedly installed on the outer wall of the sampling barrel, a sliding rod is slidably arranged inside the fixed block, and a second cleaning ring is fixedly installed on the end of the sliding rod.

[0009] Preferably, the end of the protective tube away from the second cutting ring is rotatably connected to the outer wall of the first cutting ring, and the outer wall of the rotating rod is rotatably connected to the outer wall of the protective tube. Under the protection of the protective tube, the meshing of the first bevel gear, the second bevel gear and the third bevel gear is more stably.

[0010] Preferably, the inner side of the second cutting ring is hingedly connected to the outer wall of the fixed plate, and the outer side of the first cutting ring is hingedly connected to the side of the fixed plate away from the second cutting ring. With the support of the fixed plate, the first cutting ring and the second cutting ring can be more stable when rotating, so as to improve the flatness of the soil cutting.

[0011] Preferably, the outer wall of the first cleaning ring is slidably arranged with the inner wall of the sampling tube, and the end of the first cleaning ring away from the counterweight is pointed, so as to completely clean the soil attached to the inner wall of the sampling tube.

[0012] Preferably, there are three sliding rods distributed around the center of the sampling barrel. When the outer wall of the sampling barrel needs to be cleaned, the operator only needs to turn the sampling barrel upside down, and under the action of the gravity of the sampling barrel, the outer wall of the sampling barrel will slide in contact with the inner wall of the second cleaning ring to perform the cleaning work.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The sampling device for salinized soil analysis experiment is composed of a cutting assembly as one of its components. When it is necessary to sample the saline soil, the operator holds the handle and presses the sampling tube to the desired sampling location to press the sampling tube into the soil. When the sampling tube has finished sampling, the soil needs to be completely taken out. At this time, the motor is started, and the rotating rod fixedly installed on the output end thereof begins to rotate, and the first bevel gear fixedly installed on the outer wall of the rotating rod rotates accordingly, and the second bevel gear meshing with the first bevel gear rotates accordingly, and the first cutting ring fixedly installed on the side wall of the second bevel gear rotates accordingly, and the cutter fixedly installed on the outer wall of the first cutting ring rotates accordingly to cut the soil. When the first bevel gear rotates, the third bevel gear meshing with it rotates accordingly, and the second cutting ring fixedly installed on the side wall of the third bevel gear rotates accordingly. The ring rotates accordingly, and the cutter fixedly installed on the outer wall of the second cutting ring cuts off the soil on the other side. Under the restriction of the first bevel gear, the second bevel gear and the third bevel gear, the first cutting ring and the second cutting ring rotate in opposite directions to cut the soil. Since the first cutting ring and the second cutting ring are hingedly connected to the outer wall of the fixed plate, the first cutting ring and the second cutting ring rotate stably under the support of the fixed plate, and the end of the protective tube is rotationally connected to the outer walls of the first cutting ring and the second cutting ring. Under the protection of the protective tube, the soil can be prevented from entering the first bevel gear to improve the meshing accuracy of the first bevel gear, the second bevel gear and the third bevel gear. When the first cutting ring and the second cutting ring cut off the soil, the operator can lift the handle to take out the sampled soil intact.

[0015] 2. The sampling device for salinized soil analysis experiment is composed of a cleaning component as one of its components. After sampling is completed, the soil inside the sampling tube needs to be demolded. The operator only needs to push the counterweight block to make the first cleaning ring fixedly installed at the bottom of the counterweight block slide along the inner wall of the sampling tube to push the sampled soil out of the sampling tube. Under the restriction of the first cleaning ring contacting and sliding with the inner wall of the sampling tube, the soil attached to the inner wall of the sampling tube can be cleaned accordingly. In this way, the operator does not need to clean the inner wall of the sampling tube separately. The slide rod is pressed to make the slide rod drive the second cleaning ring to slide on the outer wall of the sampling tube to clean the soil attached to the outer wall of the sampling tube.

When the sampling tube 1 has finished sampling, the soil needs to be completely taken out. At this time, the motor 312 is started, and the rotating rod 313 fixedly installed on the output end thereof begins to rotate, and the first bevel gear 314 fixedly installed on the outer wall of the rotating rod 313 rotates accordingly, and the second bevel gear 315 meshing with the first bevel gear 314 rotates accordingly, and the first cutting ring 316 fixedly installed on the side wall of the second bevel gear 315 rotates accordingly, and the cutter 320 fixedly installed on the outer wall of the first cutting ring 316 rotates accordingly to cut the soil. When the first bevel gear 314 rotates, the third bevel gear 317 meshing therewith rotates accordingly, and the second cutting ring 318 fixedly installed on the side wall of the third bevel gear 317 rotates accordingly, and the cutter 320 fixedly installed on the outer wall of the second cutting ring 318 rotates accordingly. 0 cuts off the soil on the other side, and under the restriction of the first bevel gear 314, the second bevel gear 315, and the third bevel gear 317, the first cutting ring 316 and the second cutting ring 318 rotate in opposite directions to cut off the soil. Since the first cutting ring 316 and the second cutting ring 318 are hingedly connected to the outer wall of the fixing plate 319, the first cutting ring 316 and the second cutting ring 318 rotate stably under the support of the fixing plate 319, and the end of the protective cylinder 321 is rotatably connected to the outer walls of the first cutting ring 316 and the second cutting ring 318.
