Description

Technical Field

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

[0002] Soil, as an important environmental medium, differs significantly from media such as air and water. Soil has low mobility, and pollutants migrate and transform relatively slowly after entering the soil, making it difficult to remediate once contaminated. Currently, before any soil improvement or remediation, the degree of soil contamination and the specific pollutants must be identified through testing. Testing existing contaminated soil requires sampling at a certain depth. Current soil samplers are mainly simple T-type samplers or other basic devices. While these are convenient for sampling shallow soil layers, they are inadequate for sampling deep soil layers and cannot effectively secure the equipment during sampling, potentially increasing the difficulty of the process.

[0003] A soil sampling device disclosed in Chinese utility model patent application publication CN210347193U uses a motor-driven lifting structure for sampling. However, this soil sampling device has the disadvantages of being inconvenient to move, difficult to fix during sampling, and prone to displacement. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a soil sampling device for soil remediation, so as to solve the technical problems of a soil sampling device disclosed in Chinese Utility Model Patent Application Publication CN210347193U. Although the soil sampling device uses a motor-driven lifting structure for sampling, the soil sampling device has the disadvantages of being inconvenient to move, difficult to fix during sampling, and prone to displacement during sampling.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A soil sampling device for soil remediation includes a machine housing with a handle fixed to the top and an automatically retractable submersible tube at the bottom. The submersible tube is made of stainless steel and is cylindrical. An inclined slope is formed at the bottom end of the submersible tube.

[0007] As a preferred embodiment of this utility model, the surface of the handle is fitted with a protective sleeve, which is made of rubber or fabric.

[0008] As a preferred technical solution of this utility model, the surface of the submersible tube is provided with a through-hole lever groove, which is a straight groove that extends to the inclined surface.

[0009] As a preferred embodiment of this utility model, a lever clamp is fixed to the outer wall of the machine housing, and a lever is installed on the lever clamp. The lever is a cylindrical rod structure.

[0010] As a preferred technical solution of this utility model, a straight groove bracket is fixed inside the machine box, a lifting rack is slidably connected to the surface of the straight groove bracket, a guide straight groove is opened on the surface of the lifting rack, and the guide straight groove is slidably connected to the surface of the straight groove bracket;

[0011] The machine housing has a drive gear rotatably connected to its inner bottom surface. The drive gear meshes with a lifting rack. A second pulley is provided on the surface of the drive gear. A servo motor is fixedly installed on the inner top surface of the machine housing. The servo motor has an output shaft extending forward. A first pulley is installed at the top of the output shaft of the servo motor. A V-belt connects the first pulley and the second pulley.

[0012] As a preferred embodiment of this utility model, the lifting rack is slidably connected inside the machine housing.

[0013] As a preferred embodiment of this utility model, a sample retention box is installed inside the storage box slot. The sample retention box is a square box with an open top. The sample retention box is slidably inserted into the storage box slot and can be removed from the storage box slot.

[0014] As a preferred embodiment of this utility model, an elastic ball is provided on the inner wall of the storage box groove. The elastic ball is a soft rubber ball and is glued and fixed to the inner wall of the storage box groove.

[0015] As a preferred embodiment of this utility model, a foot pedal plate is installed on the side wall of the machine housing. The foot pedal plate has an L-shaped structure, and locking bolts are installed on the surface of the foot pedal plate. The surface of the foot pedal plate is fixed to the side wall of the machine housing by the locking bolts.

[0016] This utility model features a handle fixed to the top of the machine box, making it easy for users to lift the machine box. The bottom of the machine box is equipped with an automatically retractable underground tube. The underground tube is made of stainless steel and is cylindrical. The bottom end of the underground tube has an inclined slope that guides the tube, making the bottom end of the underground tube pointed, which facilitates driving the underground tube to penetrate into the soil.

[0017] The handle of this invention is covered with a protective sleeve made of rubber or fabric, which facilitates hand grip and improves handling comfort during carrying.

[0018] After soil sampling is completed, the sample retention box in the storage box slot is slid out of the slot and placed on the ground. The sample retention box is then placed below the submerged tube, which is a hollow tube with a through-hole groove on its surface. This groove is a straight groove extending to an inclined plane, allowing the user to insert a lever into the groove and push the soil in the tube downwards. The soil falls from the hollow tube in the middle of the tube into the sample retention box below. The sample retention box is then placed in the storage box slot for storage, facilitating sample transport for testing during equipment handling. The inner wall of the storage box slot is equipped with elastic balls (soft rubber balls) that provide friction and better elastic support for the sample retention box, effectively reducing noise from the sample retention box colliding with the inner wall of the storage box during transport.

[0019] This invention features a servo motor inside the machine housing that drives a first pulley to rotate. This rotational power is then transmitted to a drive gear via belt drive, which in turn drives a lifting rack to descend, propelling the submersible tube into the soil below. The belt drive mechanism effectively prevents the submersible tube from encountering hard objects like rocks during its descent. Furthermore, the slippage between the V-belt and the pulley prevents the servo motor from becoming stuck and burning out, thus significantly extending its lifespan.

[0020] This invention features a foot-operated pressure plate installed on the side wall of the machine housing. The foot-operated pressure plate has an L-shaped structure. When sampling soil, the machine housing is first placed on the ground. At this time, the bottom surface of the foot-operated pressure plate is also in close contact with the ground. The machine housing is pressed down by the user's feet on the top surface of the foot-operated pressure plate, thereby effectively preventing the machine housing from shifting during the sampling process and improving the stability of the machine housing.

[0021] Other advantages, objectives, and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination and study, or may be learned from practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0037] Example 2

[0038] Please see Figure 1-3 This is another technical solution provided by the present invention. This embodiment has the same features as the above embodiment 1, and the similarities will not be described in this embodiment. The specific differences are as follows:

[0039] A soil sampling device for soil remediation includes a machine box 1, a handle 2 fixed to the top of the machine box 1, and an automatically retractable submersible tube 9 at the bottom of the machine box 1. The submersible tube 9 is a stainless steel tube and a cylindrical tube. An inclined slope 11 is provided at the bottom end of the submersible tube 9.

[0040] The surface of the handle 2 is fitted with a protective sleeve 3, which is made of rubber or cloth.

[0041] This utility model features a handle 2 fixed to the top of the machine box 1, making it easy for users to lift the machine box 1. The bottom of the machine box 1 is equipped with an automatically retractable underground tube 9. The underground tube 9 is a stainless steel tube with a hollow internal structure. The bottom end of the underground tube 9 has an inclined surface 11, which guides the tube so that the bottom end of the underground tube 9 is pointed, making it easier to drive the underground tube 9 into the soil.

[0042] The surface of the submersible tube 9 is provided with a through-hole lever groove 10, which is a straight groove that extends directly to the inclined surface 11. A lever clamp 7 is fixed to the outer wall of the machine housing 1, and a lever 8 is installed on the lever clamp 7. The lever 8 is a cylindrical rod structure.

[0043] After soil sampling is completed, the sample retention box 6 in the storage box 4 is slid out of the storage box 4 and placed on the ground. The sample retention box 6 is placed below the submerged tube 9, which is a hollow tube with a through-hole lever groove 10 on its surface. The lever groove 10 is a straight groove that leads to the inclined surface 11, allowing the user to hold the lever 8 and insert it into the lever groove 10 to push the soil in the submerged tube 9 downwards. The soil falls from the hollow tube in the middle of the submerged tube 9 into the sample retention box 6 below. The sample retention box 6 is then placed in the storage box 4 for storage, making it convenient to take the sample back for testing during the transport of the machine case 1. The inner wall of the storage box 4 is provided with an elastic ball 5, which is a soft rubber ball that provides friction and better elastic support for the sample retention box 6 placed on the inner wall of the storage box 4, effectively reducing the noise generated by the sample retention box 6 hitting the inner wall of the storage box 4 during transport.

[0044] Inside the machine housing 1, a straight groove bracket 15 is fixed. A lifting rack 13 is slidably connected to the surface of the straight groove bracket 15. A guide straight groove 14 is opened on the surface of the lifting rack 13. The guide straight groove 14 is slidably connected to the surface of the straight groove bracket 15.

[0045] A drive gear 19 is rotatably connected to the bottom of the machine housing 1. The drive gear 19 meshes with the lifting rack 13. A second pulley 20 is provided on the surface of the drive gear 19. A servo motor 16 is fixedly installed on the top of the machine housing 1. The servo motor 16 has an output shaft extending forward. A first pulley 17 is installed at the top of the output shaft of the servo motor 16. A V-belt 18 is connected between the first pulley 17 and the second pulley 20.

[0046] The lifting rack 13 is slidably connected to the bottom surface of the machine housing 1 inside the machine housing 1. The cross-section of the lifting rack 13 is square block, so that the lifting rack 13 can reciprocate axially on the bottom surface of the machine housing 1. The submersible tube 9 is fixed to the bottom of the lifting rack 13, thereby driving the submersible tube 9 to reciprocate up and down.

[0047] This invention utilizes a servo motor 16 inside the machine housing 1 to drive the first pulley 17 to rotate. This rotational power is then transmitted to the drive gear 19 via belt drive. The drive gear 19 drives the lifting rack 13 to descend, thereby pushing the submersible tube 9 into the soil below. The belt drive mechanism for rotating the drive gear 19 effectively prevents the submersible tube 9 from encountering hard objects such as rocks during its descent. Furthermore, the slippage between the V-belt 18 and the pulley effectively prevents the servo motor 16 from becoming stuck and burning out, thus significantly extending its service life.

[0048] The storage box 4 is equipped with a sample retention box 6. The sample retention box 6 is a square box with an open top. The sample retention box 6 is slidably inserted into the storage box 4 and can be removed from the storage box 4.

[0049] An elastic ball 5 is provided on the inner wall of the storage box 4. The elastic ball 5 is a soft rubber ball and is glued and fixed to the inner wall of the storage box 4.

[0050] After soil sampling is completed, the sample retention box 6 in the storage box 4 is slid out of the storage box 4 and placed on the ground. The sample retention box 6 is placed below the submerged tube 9, which is a hollow tube with a through-hole lever groove 10 on its surface. The lever groove 10 is a straight groove that leads to the inclined surface 11, allowing the user to hold the lever 8 and insert it into the lever groove 10 to push the soil in the submerged tube 9 downwards. The soil falls from the hollow tube in the middle of the submerged tube 9 into the sample retention box 6 below. The sample retention box 6 is then placed in the storage box 4 for storage, making it convenient to take the sample back for testing during the transport of the machine case 1. The inner wall of the storage box 4 is provided with an elastic ball 5, which is a soft rubber ball that provides friction and better elastic support for the sample retention box 6 placed on the inner wall of the storage box 4, effectively reducing the noise generated by the sample retention box 6 hitting the inner wall of the storage box 4 during transport.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
