Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, and more specifically, to a soil sampling device for plateau ecological analysis. Background Technology

[0002] Plateau ecology refers to the collective term for ecosystems formed by the interaction of biological communities and the abiotic environment in the special geographical region of plateau. When analyzing plateau ecology, soil sampling devices are required to complete the sampling operation of plateau soil. In practice, these devices have the advantages of simple operation, stable structure, and good results.

[0003] The prior art discloses a soil sampler with application number CN202221233174.9. In this utility model, the sampling cylinder is raised and lowered by rotating a threaded rod. The threaded rod is exposed to the air without a protective structure. When soil or other impurities adhere to the surface of the threaded rod, it will affect the rotation of the threaded rod to raise and lower the sampling cylinder, reducing the practicality of this utility model. At the same time, when sampling, the conical prongs need to be inserted into the soil to fix the sampling structure. However, the conical prongs have no covering structure. When foreign objects come into contact with the conical prongs, they are prone to being punctured, which poses a safety hazard to the use of this utility model.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a soil sampling device for plateau ecological analysis. It features the advantages of enabling the sampling tube to be raised and lowered without the need for a threaded rod structure, and has a covering structure that prevents the insertion pin structure from contacting external objects when not in use, thereby solving the problems mentioned in the background technology.

[0006] To achieve the advantages of lifting and lowering the sampling cylinder without the need for a threaded rod structure, having a covering structure, and preventing the plug structure from contacting foreign objects when not in use, the specific technical solution adopted by this utility model is as follows: A soil sampling device for plateau ecological analysis includes a gantry frame. The gantry frame has slots on both sides, and vertical rods are installed inside each of the slots. Lifting plates are slidably fitted onto the side walls of the vertical rods, and a sampling tube is fixedly inserted through the upper part of the lifting plates. A first piston plate is slidably installed inside the sampling tube. An electrical control box is installed on one side of the gantry frame, containing a control panel and a battery. Protective cylinders are installed on both sides of the gantry frame, and insert rods slidably pass through the upper parts of both protective cylinders. An oxygen cylinder and a suction pump are installed on the other side of the gantry frame, and a connecting hose is attached to the outlet of the oxygen cylinder. An oxygen mask is installed at one end of the connecting hose. An air storage cylinder is installed on the top surface inside the gantry frame. A filter screen is installed inside the opening of the air storage cylinder. Two sets of connecting rods slide through the upper part of the filter screen. A second piston plate is installed at the upper end of the two sets of connecting rods. The lower ends of the two sets of connecting rods are fixedly connected to the upper part of the sampling cylinder. A ventilation pipe is fixedly inserted through the upper part of the sampling cylinder. A gas guide hose is snapped into the output end of the suction pump. One end of the gas guide hose is inserted into the inside of the sampling cylinder. A suction and extraction dual-purpose air pump is installed on the upper part of the gantry frame. A gas guide hose is snapped into the output end of the suction and extraction dual-purpose air pump. One end of the gas guide hose is inserted into the inside of the air storage cylinder.

[0007] Furthermore, a first control valve is provided on the side wall of the connecting hose, a second control valve is provided on the side wall of the vent pipe, a third control valve is provided on the side wall of the air guiding hose, and a fourth control valve is provided on the side wall of the air guiding pipe.

[0008] Furthermore, concave seats are installed on both sides of the gantry frame, and mounting shafts are installed inside the two sets of concave seats via bearings. Guide wheels are fixedly sleeved on the side walls of the two sets of mounting shafts, and pull ropes are wound around the side walls of the two sets of guide wheels. Connecting blocks are installed at the upper ends of the two sets of insertion rods. One end of each set of pull ropes is fixedly connected to the two sets of connecting blocks, and a frame plate is installed at the other end of each set of pull ropes. Magnet hole plates are fixedly sleeved on the side walls of the two sets of insertion rods.

[0009] Furthermore, both sets of protective cylinders are made of iron.

[0010] Furthermore, the control panel is electrically connected to the battery, the air pump, and the dual-purpose air pump via wires.

[0011] Furthermore, the lower part of the gantry frame is equipped with four sets of casters.

[0012] Compared with the prior art, this utility model provides a soil sampling device for plateau ecological analysis, which has the following beneficial effects: (1) This utility model adopts a first piston plate, an air storage cylinder, and a second piston plate. In actual use of the soil sampling device for plateau ecological analysis, the operator first manually opens and closes the second control valve and the fourth control valve, and then uses the control panel to make the suction and extraction dual-purpose air pump work. Air can enter the interior of the air storage cylinder through the air guide pipe. This part of the air can push the second piston plate down. The down-moving second piston plate can make the sampling cylinder down through two sets of connecting rods. The down-moving sampling cylinder can be inserted into the soil. The soil inside the sampling cylinder can push the first piston plate to move. When the amount of soil sampled reaches the expected level, the control panel is used to make the suction and extraction dual-purpose air pump work again, and the air inside the air storage cylinder is extracted through the air guide pipe. A negative pressure environment is formed inside the air storage cylinder. The first piston plate can be extracted through two sets of connecting rods. The sampling tube is moved upwards and reset. After the sampling tube has been reset, the second and fourth control valves are closed, and then the third control valve is opened and closed. Using the control panel, the air pump is activated, and air enters the sampling tube through the connecting hose. This air pushes the first piston plate to move, and the moving first piston plate pushes out the soil inside the sampling tube. Since the oxygen content is thin in high-altitude areas, the operator can cover their nose with an oxygen mask and then open and close the first control valve. The oxygen inside the oxygen tank enters the oxygen mask through the connecting hose, thus providing oxygen to the operator. Through the first piston plate, the air storage tank, and the second piston plate, the sampling tube can be raised and lowered without the need for a threaded rod structure, which improves the practicality of the soil sampling device for high-altitude ecological analysis.

[0013] (2) This utility model adopts a protective cylinder and a plug rod. Before actually using the soil sampling device for plateau ecological analysis, the gantry is moved to a suitable position using four sets of universal wheels. Then, the operator steps on the two sets of connecting blocks with his feet. The two sets of plug rods will gradually move out of the two sets of protective cylinders and finally insert into the soil. At this time, the gantry can be fixed. After the sampling work is completed, the operator steps on the two sets of frame plates with his feet. The two sets of pull ropes can be used to move the two sets of plug rods upward. When the two sets of magnetic perforated plates are attracted to the inner top surface of the two sets of protective cylinders, the two sets of plug rods are stably fixed. The two sets of concave seats play the role of installing the two sets of mounting shafts and the two sets of guide wheels. The two sets of guide wheels play the role of supporting the two sets of pull ropes. The protective cylinder and plug rod have a covering structure. When not in use, the plug rod structure can be prevented from contacting foreign objects, which ensures the safety of the use of the soil sampling device for plateau ecological analysis.

[0020] In one embodiment, a first control valve is provided on the side wall of the connecting hose 9, a second control valve is provided on the side wall of the vent pipe 11, a third control valve is provided on the side wall of the air guide hose 13, and a fourth control valve is provided on the side wall of the air guide pipe 18.

[0021] In one embodiment, concave seats 21 are installed on both sides of the gantry frame 1, and mounting shafts 22 are installed inside the two sets of concave seats 21 through bearings. Guide wheels 23 are fixedly sleeved on the side walls of the two sets of mounting shafts 22, and pull ropes 24 are wound around the side walls of the two sets of guide wheels 23. Connecting blocks 25 are installed at the upper ends of the two sets of insertion rods 20.

[0022] In one embodiment, both sets of protective cylinders 19 are made of iron material, which provides protection for the adsorption of the two sets of magnetic perforated plates 27.

[0023] In one embodiment, the control panel is electrically connected to the battery, the vacuum pump 12, and the dual-purpose vacuum pump 17 via wires. The control circuit of the control panel can be implemented by simple programming by those skilled in the art and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0024] In one embodiment, four sets of casters are installed on the lower part of the gantry frame 1.

[0025] Working principle: In actual use of the soil sampling device for plateau ecological analysis, the operator first manually opens and closes the second and fourth control valves. Then, using the control panel, the dual-purpose suction and extraction air pump 17 is activated. Air enters the air storage cylinder 7 through the air guide pipe 18. This air pushes the second piston plate 16 downwards. The downward-moving second piston plate 16, via two sets of connecting rods 15, causes the sampling cylinder 5 to move downwards. The downward-moving sampling cylinder 5 can be inserted into the soil. The soil inside the sampling cylinder 5 pushes the first piston plate 6 to move. When the expected amount of soil sampled is reached, the control panel is used again to activate the dual-purpose suction and extraction air pump 17, and the remaining soil inside the air storage cylinder 7 is then removed. Air is drawn out through the air duct 18, creating a negative pressure environment inside the air storage cylinder 7. The first piston plate 6 can move the sampling cylinder 5 upwards and reset via two sets of connecting rods 15. After the sampling cylinder 5 has reset, the second and fourth control valves are closed, followed by the opening and closing of the third control valve. Using the control panel, the air pump 12 is activated, allowing air to enter the sampling cylinder 5 through the connecting hose 9. This air pushes the first piston plate 6, which in turn pushes out the soil inside the sampling cylinder 5. Since oxygen levels are low in high-altitude areas, operators can cover their noses with an oxygen mask 10 before opening and closing the first control valve. Oxygen can enter the oxygen mask 10 through the connecting hose 9, thus providing oxygen to the operator. The sampling cylinder 5 can be raised and lowered without the need for a threaded rod structure, thanks to the first piston plate 6, the air storage cylinder 7, and the second piston plate 16, improving the practicality of the soil sampling device for plateau ecological analysis. Before actual use, the gantry 1 is moved to a suitable position using four sets of casters. Then, the operator steps on the two connecting blocks 25, causing the two insertion rods 20 to gradually move out of the two protective cylinders 19 and eventually insert into the soil. At this point, the gantry can be... 1. After sampling is completed, the operator steps on the two sets of frame plates 26. The two sets of pull ropes 24 can be used to move the two sets of insertion rods 20 upward. When the two sets of magnetic perforated plates 27 are respectively attracted to the inner top surface of the two sets of protective cylinders 19, the two sets of insertion rods 20 are stably fixed. The two sets of concave seats 21 serve to install the two sets of mounting shafts 22 and the two sets of guide wheels 23. The two sets of guide wheels 23 serve to support the two sets of pull ropes 24. The protective cylinders 19 and insertion rods 20 have a covering structure, which can prevent the insertion structure from contacting foreign objects when not in use, thus ensuring the safety of the use of the soil sampling device for plateau ecological analysis.
