Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to a sampling device for soil quality monitoring. Background Technique

[0002] At present, agroforestry is a research discipline or practical method that combines land use between forestry and agriculture. Now, special attention is paid to the planting and development of agroforestry. During the development of agroforestry, some problems are encountered. When developing agroforestry, it is necessary to first sample and detect the soil of the development land. The soil sampler is a tool often used in soil quality monitoring. The soil sample is taken out by the sampler, and then the soil sample is analyzed to obtain the content of soil monitoring indicators.

[0003] In the existing soil sampling device, usually a sampling cylinder is inserted into the soil. After pulling it out, the lid on the side is opened to sample the collected soil. However, the cutter head at the bottom of the sampling cylinder will be severely worn after long-term use, which is inconvenient to replace. Moreover, when cleaning the sampling cylinder, the dead corners inside are difficult to wash clean, causing inconvenience to cleaning. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a sampling device for soil quality monitoring, which solves the problems put forward in the above background technique.

[0005] To achieve the above object, the utility model is realized through the following technical solutions: A sampling device for soil quality monitoring includes a top plate. Pillars are fixedly installed at both ends of the top plate. A first sliding plate is slidably installed between the two pillars. A rotating cylinder is rotatably installed inside the first sliding plate. An auxiliary ring is fixedly installed on the outer wall of the rotating cylinder. The auxiliary ring is rotatably connected to the first sliding plate. A second sliding groove is opened inside the rotating cylinder. Two second springs are fixedly installed inside the second sliding groove. A second sliding plate is slidably installed inside the second sliding groove. One side of the second sliding plate is fixedly connected to one ends of the two second springs. A sliding column is slidably installed inside the second sliding groove. The sliding column passes through the inside of the second sliding plate and is fixedly connected to it. A third sliding groove is opened inside the rotating cylinder. Three third springs are fixedly installed inside the third sliding groove. An arc-shaped sliding block is slidably installed inside the third sliding groove. One side of the arc-shaped sliding block is fixedly connected to one ends of the three third springs. The sliding column extends into the third sliding groove and is slidably connected.

[0006] Preferably, a second gear is rotatably installed inside the first sliding plate. A first gear is fixedly installed on the outer wall of the rotating cylinder. The first gear is rotatably connected to the inside of the first sliding plate. The first gear is meshed with the second gear. A second motor is fixedly installed on the top of the first sliding plate. The output end of the second motor is fixedly connected to the central position of the second gear. By starting the second motor, the first gear and the second gear rotate, thereby driving the rotating cylinder to rotate, which facilitates inserting the rotating cylinder into the soil interior.

[0007] Preferably, a first collecting cylinder and a second collecting cylinder are inserted into the rotating cylinder. Fixed columns are fixedly installed on the tops of the first collecting cylinder and the second collecting cylinder. Slots are provided on one side of the two fixed columns. The two fixed columns are inserted into the inside of the rotating cylinder. The arc-shaped sliding block is inserted into the two slots. Four slots are provided on one side of the first collecting cylinder. Four insertion blocks are fixedly installed on one side of the second collecting cylinder. The four insertion blocks are respectively inserted into the four slots. Knife discs are fixedly installed at the bottoms of the first collecting cylinder and the second collecting cylinder. After inserting the four insertion blocks into the four slots and then inserting them into the rotating cylinder, the arc-shaped sliding block is inserted into the two slots to limit its position, preventing the first collecting cylinder and the second collecting cylinder from separating from the inside of the rotating cylinder during use.

[0008] Preferably, first sliding grooves are provided inside the two support columns. Lead screws are rotatably installed inside the two first sliding grooves. The first sliding plate is slidably connected between the two first sliding grooves and is threadedly connected to the two lead screws. Two connecting bottom columns are fixedly installed between the two support columns. A first motor is fixedly installed on the top of one of the support columns. The output end of the first motor is fixedly connected to one end of one of the lead screws. By starting the first motor, the lead screw rotates, driving the first sliding plate to move downward.

[0009] Preferably, square grooves are provided inside the two support columns. A first bevel gear and a second bevel gear are rotatably installed inside the two square grooves. The first bevel gear is meshed with the second bevel gear. One end of each of the two lead screws is respectively inserted into the two square grooves and is fixedly connected to the inside of the first bevel gear. A connecting column is fixedly installed between the two second bevel gears. The connecting column is rotatably connected to the top plate. When one of the first bevel gear and the second bevel gear rotates, it can drive the other first bevel gear and the second bevel gear to rotate, thereby enabling the two lead screws to rotate together.

[0010] Preferably, a placement groove is provided on the top of the first sliding plate, and a bottom cover is movably installed inside the placement groove. The inside of the bottom cover is plugged into the two cutter discs, and two rollers are rotatably installed at the bottom of the two pillars. The staff holds the bottom cover and covers the bottom of the cutter disc to prevent the staff from being injured when taking out the first collection barrel and the second collection barrel.

[0011] The utility model provides a sampling device for soil quality monitoring, which has the following beneficial effects:

[0012] 1. The sampling device for soil quality monitoring presses the sliding column to make the sliding column against the arc-shaped sliding block, and pushes the arc-shaped sliding block to make it disengage from the inside of the two card slots. At this time, the first collection tube and the second collection tube will fall together, making it convenient for the staff to replace the collection tube and the knife disc.

[0013] 2. The sampling device for soil quality monitoring separates the first collecting tube from the second collecting tube by disengaging the four plugs from the inside of the four slots, so that the staff can clean the first collecting tube and the second collecting tube conveniently after the sampling is completed, thereby avoiding the situation where there are dead corners inside that cannot be cleaned properly.
