Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, and in particular to an environmental monitoring soil sampling device. Background Technology

[0002] Piston-type soil samplers use the suction force of a piston to draw soil into a sampling tube. They typically consist of a hollow sampling tube and a movable piston. Once the sampling tube is inserted into the soil, pulling the piston creates a negative pressure inside the tube, drawing the soil in.

[0003] Existing soil sampling machines are long, cannot be disassembled, are not easy to store, and are difficult to rotate during drilling, resulting in low work efficiency and inconvenience of use.

[0004] An existing patent (publication number: CN220708774U) discloses an environmental monitoring soil sampling device, including a bracket. An engine is fixedly connected to the upper outer surface of the bracket near the left side, and a gasoline can is fixedly connected to the right outer surface of the engine. A switch is fixedly connected to the upper outer surface of the bracket near the right side. A movable block is rotatably connected to the lower outer surface of the bracket near the middle. A second bolt is rotatably connected to the right outer surface of the movable block near the lower end, and a rotating rod is rotatably connected to the lower inner surface of the movable block. This environmental monitoring soil sampling device has advantages such as being detachable after use, facilitating storage, reducing space requirements, and requiring less effort during drilling by using a threaded connection, thus improving work efficiency. It solves the problems of non-detachability, laborious drilling, and low efficiency.

[0005] To address the aforementioned issues, existing patents offer solutions. However, existing piston-type soil samplers lack a structure for soil pretreatment, making it difficult for the sampler to break down the initial soil structure. The piston's negative pressure cannot effectively overcome soil resistance to draw the sample into the sampling tube, requiring repeated insertion and removal of the sampling tube. This cumbersome process, coupled with repeated operations, excessively damages the soil structure, severely impacting sample integrity and making it prone to breakage and fragmentation, thus reducing sample quality.

[0006] Therefore, an environmental monitoring soil sampling device is proposed. Utility Model Content

[0007] The purpose of this invention is to provide an environmental monitoring soil sampling device that can solve the problems of existing piston-type soil samplers, which lack a structure for pre-treatment of the soil. This makes it difficult for the sampler to break down the initial soil structure, and the piston negative pressure cannot effectively overcome soil resistance to draw the sample into the sampling tube. The sampling tube needs to be repeatedly inserted and removed, which is cumbersome. Moreover, during repeated operations, the soil structure is excessively damaged, the integrity of the sample is seriously affected, and the sample is prone to breakage and fragmentation, thereby reducing the quality of the sample.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an environmental monitoring soil sampling device, comprising a soil sampler body, a connecting plate welded to the surface of the soil sampler body, a soil pretreatment mechanism welded to the top of the connecting plate, auxiliary fixing mechanisms fixedly connected to both sides of the connecting plate, the soil pretreatment mechanism comprising a water storage tank, a filling pipe, a micro water pump, a connecting hose, a guide pipe, a connecting ring, and several nozzles, the water storage tank being welded to the top of the connecting plate, the filling pipe being fixedly connected to the top of the water storage tank, the micro water pump being installed on the rear side of the top of the connecting plate, the front end of the micro water pump being fixedly connected to the bottom of the rear side of the water storage tank, the rear end of the micro water pump penetrating and extending to the bottom of the connecting plate, the connecting hose being fixedly connected to the bottom of the rear end of the micro water pump, the guide pipe being fixedly connected to the bottom of the connecting hose, the connecting ring being welded to the bottom of the guide pipe, and the nozzles being installed on the surface of the connecting ring.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 The present invention provides the following technical solution:

[0027] An environmental monitoring soil sampling device includes a soil sampler body 1, a connecting plate 2 welded to the surface of the soil sampler body 1, a soil pretreatment mechanism 3 welded to the top of the connecting plate 2, and auxiliary fixing mechanisms 4 fixedly connected to both sides of the connecting plate 2. The soil pretreatment mechanism 3 includes a water storage tank 31, a filling pipe 32, a micro water pump 33, a connecting hose 34, a guide pipe 35, a connecting ring 36, and several nozzles 37. The water storage tank 31 is welded to the top of the connecting plate 2, the filling pipe 32 is fixedly connected to the top of the water storage tank 31, the micro water pump 33 is installed on the rear side of the top of the connecting plate 2, the front end of the micro water pump 33 is fixedly connected to the bottom of the rear side of the water storage tank 31, the rear end of the micro water pump 33 passes through and extends to the bottom of the connecting plate 2, the connecting hose 34 is fixedly connected to the bottom of the rear end of the micro water pump 33, the guide pipe 35 is fixedly connected to the bottom of the connecting hose 34, the connecting ring 36 is welded to the bottom of the guide pipe 35, and the nozzles 37 are installed on the surface of the connecting ring 36.

[0028] In this embodiment: by setting the soil sampler body 1 as a piston-type soil sampler, soil samples can be collected, and the connecting plate 2 can be supported and limited. The connecting plate 2 connects the soil sampler body 1, the soil pretreatment mechanism 3 and the auxiliary fixing mechanism 4. The water storage tank 31 provides the water source required for pretreatment. The filling pipe 32 facilitates rapid replenishment of water. The micro water pump 33 delivers water to the sampling area, improving the sampling success rate of dry and hard soil. The connecting hose 34 is made of flexible material and can be bent to adjust the position of the nozzle 37 to adapt to different terrains and sampling angle requirements. The conical bottom design of the guide tube 35 facilitates insertion into the soil surface, reduces water flow diffusion, and improves local wetting efficiency. The connecting ring 36 can support and limit the nozzle 37. The nozzle 37 can spray water in a fan shape to cover the entire sampling area and ensure uniform soil wetting.

[0029] Specifically, such as Figure 4 , Figure 5 As shown, the auxiliary fixing mechanism 4 includes a limiting plate 41, a torsion spring 42, a support plate 43, a slide groove 44, a lifting plate 45, three ground insertion rods 46, a foot pedal 47, a fixing plate 48, and a return spring 49. The limiting plate 41 is fixedly connected to both sides of the connecting plate 2.

[0030] Specifically, such as Figure 4 , Figure 5 As shown, the torsion spring 42 is rotatably connected to the inner side of the limiting plate 41, the support plate 43 is welded to the surface of the torsion spring 42, the slide groove 44 is opened at the bottom of the inner side of the support plate 43, and the lifting plate 45 is slidably connected to the inner side of the slide groove 44.

[0031] Specifically, such as Figure 4 , Figure 5 As shown, the ground insertion rod 46 is welded to the bottom of the lifting plate 45, the foot pedal 47 is welded to both sides of the lifting plate 45, the fixing plate 48 is welded to the bottom surfaces of both sides of the support plate 43, the return spring 49 is installed on the top of the fixing plate 48, and the top of the return spring 49 is installed on the bottom of the foot pedal 47.

[0032] In this embodiment: the limiting plate 41 can support and limit the torsion spring 42, and the torsion spring 42 can provide elastic support, so that the support plate 43 can adjust the angle according to the terrain, ensuring that the device can remain vertical on slopes or uneven ground. The slide 44 can guide and limit the movement of the lifting plate 45. The lifting plate 45 can slide along the slide 44, driving the ground insertion rod 46 to adjust its height. After the ground insertion rod 46 is inserted into the soil, it provides anti-overturning force and reduces shaking during sampling. The foot pedal 47 makes it easy for the operator to quickly insert the ground insertion rod 46 by stepping on it, improving the fixing efficiency. The fixing plate 48 can support and limit the return spring 49. The return spring 49 makes the lifting plate 45 automatically return after being pulled out, simplifying the operation process.

[0033] Specifically, such as Figure 2 As shown, a sealing ring 5 is fixedly connected to the side of the connecting hose 34 near the drain end of the micro water pump 33, and the surface of the sealing ring 5 is coated with anti-corrosion paint.

[0034] Specifically, such as Figure 3 As shown, the bottom of the guide tube 35 is tapered, and the surface of the guide tube 35 is coated with an anti-corrosion coating.

[0035] In this embodiment: by setting a sealing ring 5 made of corrosion-resistant rubber, water leakage is prevented at the connection between the connecting hose 34 and the drain end of the micro water pump 33. By setting an anti-corrosion coating, the corrosion of chemicals in the water is effectively resisted, extending the sealing life. By setting the bottom of the guide tube 35 to be conical, the conical bottom design facilitates insertion into the soil surface. By setting an anti-corrosion coating, the corrosion of the guide tube 35 by the soil is reduced, extending its service life.

[0036] Specifically, such as Figure 5 As shown, a reinforcing ring 6 is welded to the side of the ground insertion rod 46 near the lifting plate 45, and the surface of the reinforcing ring 6 is coated with anti-corrosion paint.

[0037] Specifically, such as Figure 1 As shown, a reinforcing base 7 is installed at the bottom of the micro water pump 33, and the bottom of the reinforcing base 7 is welded to the top of the connecting plate 2.

[0038] In this embodiment: by setting a reinforcing ring 6, the strength of the connection between the ground insertion rod 46 and the lifting plate 45 is enhanced; by setting an anti-corrosion coating, the reinforcing ring 6 is protected, reducing the impact of damp or saline soil; and by setting a reinforcing base 7, the micro water pump 33 is supported, reducing the vibration generated during operation.

[0039] Working principle: First, the operator fills the water tank 31 with clean water through the filling pipe 32. Then, the operator moves the soil sampler body 1 to the desired sampling location and adjusts the angle of the support plate 43 of the auxiliary fixing mechanism 4 according to the terrain of the sampling location, using the elastic support of the torsion spring 42, so that the device can adapt to slopes or uneven ground and ensure that the soil sampler body 1 remains vertical. Then, the operator steps on the foot pedal 47, which drives the lifting plate 45 to slide down the slide 44 and insert the ground insertion rod 46 into the soil. After that, the operator starts the micro water pump 33, which draws water from the water tank 31. Water is pumped through the drain end to the connecting hose 34. The water flows through the connecting hose 34 into the guide pipe 35, and then is sprayed in a fan shape on the sampling area through the nozzle 37 on the surface of the connecting ring 36. Finally, the operator uses the piston-type soil sampler body 1 to sample the pretreated soil. After sampling is completed, the operator moves the foot pedal 47 upward to separate the ground insertion rod 46 from the soil. At this time, under the action of the return spring 49, the lifting plate 45 slides up and returns to its original position along the slide groove 44, driving the ground insertion rod 46 to return to the inner side of the slide groove 44. Then, the operator can move the device to the next sampling point.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
