Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring, specifically a rapid soil sampling device for environmental monitoring. Background Technology

[0002] Soil monitoring is basically the same as water and air quality monitoring. By using appropriate measurement methods, various physicochemical properties of soil are measured, such as iron, manganese, total potassium, organic matter, total nitrogen, available phosphorus, total phosphorus, moisture, total arsenic, available boron, fluoride, chloride, mineral oil, and total salt content, to achieve purposes such as monitoring the current status of soil quality; monitoring soil pollution incidents; dynamic monitoring of land treatment of pollutants; and investigating soil background values.

[0003] Current rapid soil sampling devices for environmental monitoring, as described in patent CN208270236U, include a drill bit, a pedal, a connector, and a handle. The drill bit, pedal, and handle are all threaded onto the connector. The drill bit is installed at the bottom of the connector, the handle is installed at the top of the connector, and the pedal is movably connected to the connector. By rotating the thread, the pedal can be moved to any position on the connector.

[0004] Regarding the aforementioned technologies, the inventors believe that the fixed connection between the drill bit and the connecting pipe, which prevents them from being folded, results in the device occupying a large space, making it inconvenient to carry. Utility Model Content

[0005] The purpose of this invention is to provide a rapid soil sampling device for environmental testing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0015] As a further embodiment of this utility model: a throttle handle is symmetrically and fixedly connected to the outer side of the rotating tube, and a lever is fixedly and through one side of the rotating shaft.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] With the above-mentioned structure, the interplay of the slot, rotating shaft, threaded rod, and insert post allows the threaded rod to rotate when the rotating shaft rotates. The threaded rod can be screwed into the interior of the rotating tube as it rotates. After the insert post is pulled out from the slot, the rotating tube can be inserted into the soil sampling tube. Then, the insert post is inserted into the upper slot, thereby achieving the folding of the entire soil sampling device. This effectively reduces the space occupied by the entire soil sampling device and makes it more convenient to carry. Attached Figure Description

[0025] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0026] Please see Figure 1-4 A rapid soil sampling device for environmental monitoring includes a sampling mechanism 1, which includes a soil sampling cylinder 101. The soil sampling cylinder 101 is designed to be inserted into the soil, and when removed from the soil, it carries out the soil inside, thereby achieving soil sampling. The bottom of the soil sampling cylinder 101 has multiple evenly spaced serrated grooves 103. These grooves are designed to cut the soil during rotation, making it easier and less strenuous to insert the soil sampling cylinder 101 into the soil. The bottom of the soil sampling cylinder 101 has a matching cover 104. The cover 104 is designed to fit over the bottom of the soil sampling cylinder 101, thereby covering the serrated grooves 103 and reducing the probability of the serrated grooves 103 being exposed during transport and potentially injuring nearby personnel.

[0027] A magnet 105 is embedded in the inner wall of the shielding sleeve 104. The magnet 105 is designed to adhere to the outside of the soil sampling cylinder 101 using its own magnetism after the shielding sleeve 104 is fitted onto the outside of the soil sampling cylinder 101, thereby reducing the probability of the shielding sleeve 104 detaching from the bottom of the soil sampling cylinder 101. A spiral blade 102 is fixedly connected to the outside of the soil sampling cylinder 101. The spiral blade 102 is designed to rotate synchronously with the soil sampling cylinder 101, so that the spiral blade 102 can be screwed into the soil when rotating, making it easier and less strenuous for the soil sampling cylinder 101 to be inserted into the soil. The rotating mechanism 2 includes a guide ring 201 fixedly connected to the top of the soil sampling cylinder 101. Multiple reinforcing ribs 202 are fixedly connected in a ring array on the outer side of the guide ring 201. Each set of reinforcing ribs 202 is fixedly connected to the soil sampling cylinder 101. The reinforcing ribs 202 are used to further connect and fix the soil sampling cylinder 101 and the guide ring 201, thereby improving the connection stability between the soil sampling cylinder 101 and the guide ring 201.

[0028] A rotating tube 203 is slidably connected inside the guide ring 201. Guide bars 204 are symmetrically fixedly connected to the outer side of the rotating tube 203. Guide grooves 205, adapted to the guide bars 204, are symmetrically formed on the inner wall of the guide ring 201. The guide bars 204 and guide grooves 205 guide the sliding of the rotating tube 203 and, when the rotating tube 203 rotates, drive the guide ring 201 and the soil sampling cylinder 101 to rotate accordingly. A handle 210 is symmetrically fixedly connected to the outer side of the rotating tube 203, facilitating the adjustment of the rotation of the rotating tube 203.

[0029] One end of the rotating tube 203 extends into the interior of the soil sampling cylinder 101. A symmetrically sliding insert 206 passes through the interior of the guide ring 201. Slots 209, adapted to the inserts 206, are symmetrically provided on both sides of the rotating tube 203. Two sets of inserts 206 are inserted into the lower two sets of slots 209, respectively. The inserts 206 are designed to limit the rotation of the rotating tube 203 after insertion into the slots 209. Pull blocks 207 are fixedly connected to the opposite sides of the two sets of inserts 206. Springs 208 are fixedly connected between the pull blocks 207 and the guide ring 201. The springs 208 use their elasticity to pull the pull blocks 207 and the inserts 206 towards one side of the rotating tube 203, reducing the probability of the inserts 206 disengaging from the slots 209.

[0030] The sampling mechanism 3 includes a threaded rod 301 internally threaded to a rotating tube 203. A push block 302 is fixedly connected to the bottom of the threaded rod 301. The threaded rod 301 is configured to drive the push block 302 up and down during rotation, so that when the push block 302 moves downward, it can push out the soil collected inside the soil sampling cylinder 101. A rotating shaft 303 is slidably connected internally to the threaded rod 301. The rotating shaft 303 is rotatably connected to the rotating tube 203. Positioning blocks 305 are symmetrically fixedly connected to the outer side of the rotating shaft 303. Positioning grooves 304 that are adapted to the positioning blocks 305 are symmetrically opened inside the threaded rod 301. The rotating shaft 303 is configured to drive the positioning blocks 305 to rotate during rotation, so that the positioning blocks 305 can actuate the rotating shaft 303. A lever 306 is fixedly fixed through one side of the rotating shaft 303. The lever 306 is configured to adjust the rotation of the rotating shaft 303.

[0031] In use, the soil sampling tube 101 is vertically aligned with the sampling location. Then, the rotating tube 203 is rotated, causing the soil sampling tube 101 and the spiral blade 102 to rotate. This allows the serrated groove 103 to cut at the corresponding location, while the spiral blade 102 gradually spirals into the soil, causing the soil sampling tube 101 to be inserted into the soil as well. Next, the rotating tube 203 and the soil sampling tube 101 are rotated in the opposite direction, causing the spiral blade 102 and the soil sampling tube 101 to spiral out of the soil. The soil inside the soil sampling tube 101 remains inside the soil sampling tube 101 and is removed from the surface soil along with the soil sampling tube 101. Next, the lever 306 is rotated, causing the rotating shaft 303 to rotate. The rotating shaft 303 then rotates the threaded rod 301, which in turn rotates downwards along the interior of the rotating tube 203, causing the push block 302 to move downwards. As the push block 302 moves downwards, it pushes out the soil remaining inside the soil sampling cylinder 101, thus completing the soil sampling. After sampling is complete, the rotating shaft 303 can be rotated in the opposite direction, causing the threaded rod 301 to rotate in the opposite direction, thus causing the threaded rod 301 to screw into the interior of the rotating tube 203. This causes the pusher block 302 to move upwards until the rotating shaft 303 moves upwards and contacts the bottom wall of the rotating tube 203. Then, the pull blocks 207 on both sides are pulled, causing the pull blocks 207 to drive the two inserts 206 to move in opposite directions, thus disengaging them from the interior of the two lower sets of slots 209. After that, the rotating tube 203 moves downwards, inserting itself into the soil sampling cylinder 101, until the two upper sets of slots 209 move with the rotating tube 203 and align with the two sets of inserts 206. Then, the pulling of the pull block 207 is stopped, causing the spring 208 to return to its original deformation and pull the pull block 207 back towards the rotating tube 203. The device moves to one side, causing the insert 206 to be inserted into the upper slot 209, thereby limiting the rotation tube 203 and enabling the entire soil sampling device to be folded, reducing the space occupied by the entire soil sampling device and making it more convenient to carry. Then, the cover 104 is put on the bottom of the soil sampling cylinder 101, so that the magnet 105 inside the cover 104 is attracted to the outer wall of the soil sampling cylinder 101, thereby fixing the cover 104. At the same time, the cover 104 can cover the soil sampling cylinder 101, reducing the probability of the serrated groove 103 scratching the surrounding personnel when carrying the entire soil sampling device.

[0032] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
