DETAILED DESCRIPTION

[0018] In order to make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0019] Embodiment 1 like Figure 1 As shown, an engineering sampling device includes a spiral cutter body 1 composed of multiple spiral monomers and a cutting cutter body 2 composed of multiple cutting monomers. The cutting cutter body 2 is located on the inner side of the spiral cutter body 1, and the spiral cutter body 1 is connected to a spiral drive member for spirally inserting into the soil layer. The spiral drive member drives the spiral cutter body 1 to rotate, so that the head of the spiral drive member is inserted into the soil layer from top to bottom in a spiral rotation posture, and the channel formed is for the spiral monomer located at the upper end to be inserted, so as to cut into the soil layer from top to bottom in the form of small area contact, and achieve the purpose of avoiding affecting the soil layers at different depths.

[0020] It should be mentioned that a blade gap 3 is formed between two adjacent spiral monomers. The width of the cutting blade 2 is greater than the width of the blade gap 3, and the cutting blade 2 is connected to a cutting drive member for driving and running in the axial direction and covering the blade gap 3. The cutting drive member drives the cutting monomer to move downward from the inner side of the corresponding spiral monomer and cuts the soil layer between the blade gap 3, thereby reducing the cutting effect on soil layers of different depths based on the cutting form of small spacing.

[0021] In order to improve the cutting effect of the spiral cutter body 1 and the cutting cutter body 2 on soil layers of different depths, an outer lower cutting surface 11 is provided at the outer lower end of the spiral cutter body 1, and an inner lower cutting surface 21 is provided at the inner lower end of the cutting cutter body 2. The outer lower cutting surface 11 cooperates with the inner lower cutting surface 21 to achieve effective cutting of the soil layer, thereby reducing the cutting effect on soil layers of different depths by increasing the contact pressure with the soil layer.

[0022] like Figure 1 , Figure 2As shown, a driving disc 4 for driving rotation is provided at the top of the spiral cutter body 1, and a positioning shaft column 5 is detachably connected at the axis of the driving disc 4. The bottom height of the positioning shaft column 5 is lower than the bottom height of the spiral cutter body 1. Therefore, when the soil layer is cut to achieve an effective extraction depth that is consistent with the actual soil layer, the positioning shaft column 5 is in contact with the surface of the soil layer to achieve the positioning function, and then the spiral cutter body 1 is used to drive the cutting cutter body 2 and the positioning shaft column 5 to perform synchronous rotational motion, so that the spiral cutter body 1, the cutting cutter body 2 and the positioning shaft column 5 can perform synchronous linear movement, and then a complete soil layer structure with consistent depth is obtained.

[0023] In the first embodiment of the present application, the engineering sampling device is a small handheld sampling device, and a polygonal connecting column 51 is provided at the top of the positioning shaft column 5. The polygonal connecting column 51 and the driving disk 4 form a spiral driving member, and are used to be externally connected to the output device to achieve the purpose of driving rotation. In order to prevent the positioning shaft column 5 from penetrating deep into the soil layer and affecting the diffusion of the soil layer to the outside of the positioning shaft column 5 and affecting the structure of the soil layers at different depths, a discharge hole 52 is provided in the positioning shaft column 5. The discharge hole 52 is used to discharge the soil layer structure located at the positioning shaft column 5, so as to improve the sampling efficiency and the sampling accuracy of the soil layers at different depths.

[0024] At the same time, the cutting drive member is a driving ring body 6 located at the top of the driving disk 4. The bottom of the driving ring body 6 passes through the driving disk 4 from top to bottom and is used to drive the cutting blade 2 to move downward. The effect of effectively driving the driving ring body 6 to run can be achieved by pulling and pressing the driving ring body 6 by hand. Among them, a cutting capsule 7 is arranged at the bottom of the driving disk 4. A lower driving plate 71 for relatively upward and downward sealing movement is arranged at the bottom of the cutting capsule 7. The lower driving plate 71 is connected to the cutting capsule 7 by a flexible sealing material such as rubber, and the lower driving plate 71 is connected and fixed to the bottom of the driving ring body 6. It should be mentioned that a capsule cavity 72 filled with liquid is arranged in the cutting capsule 7, and an elastomer for pushing the lower driving plate 71 downward is arranged in the capsule cavity 72. The top of the cutting blade body 2 is detachably connected to the plug-in portion 73 plugged into the cutting capsule 7, and the plug-in portion 73 is in sealed sliding connection with the cutting capsule 7 to prevent the liquid in the capsule cavity 72 from overflowing and to push the cutting blade body 2 downward to achieve the purpose of cutting the soil layer at a corresponding depth through the liquid in the capsule cavity 72. The liquid can be oil or the like, which will not be described in detail here.

[0025] When the lower driving plate 71 moves upward, the cutting blade 2 descends and forms a gap between the lower driving plate 71 and the topmost soil layer, which has the effect of forming negative pressure and adsorbing the soil layer, and thus effectively prevents the soil layer from falling off from between the spiral blade 1 and the cutting blade 2 of the engineering sampling device due to gravity. After the engineering sampling device is taken out of the soil layer, the lower driving plate 71 and the cutting blade 2 are reset, which will expose the soil layer between the blade gaps 3, so as to be used for direct sampling and detection of soil layers at different depths, thereby significantly improving the sampling and detection accuracy of soil layers at different depths.

[0026] Embodiment 2 like Figure 3 As shown, an engineering sampling device includes a spiral cutter body 1 composed of multiple spiral monomers and a cutting cutter body 2 composed of multiple cutting monomers. The cutting cutter body 2 is located on the inner side of the spiral cutter body 1, and the spiral cutter body 1 is connected to a spiral drive member for spirally inserting into the soil layer. The spiral drive member drives the spiral cutter body 1 to rotate, so that the head of the spiral drive member is inserted into the soil layer from top to bottom in a spiral rotation posture, and the channel formed is for the spiral monomer located at the upper end to be inserted, so as to cut into the soil layer from top to bottom in the form of small area contact, and achieve the purpose of avoiding affecting the soil layers at different depths.

[0027] It should be mentioned that a blade gap 3 is formed between two adjacent spiral monomers. The width of the cutting blade 2 is greater than the width of the blade gap 3, and the cutting blade 2 is connected to a cutting drive member for driving and running in the axial direction and covering the blade gap 3. The cutting drive member drives the cutting monomer to move downward from the inner side of the corresponding spiral monomer and cuts the soil layer between the blade gap 3, thereby reducing the cutting effect on soil layers of different depths based on the cutting form of small spacing.

[0028] In order to improve the cutting effect of the spiral cutter body 1 and the cutting cutter body 2 on soil layers of different depths, an outer lower cutting surface 11 is provided at the outer lower end of the spiral cutter body 1, and an inner lower cutting surface 21 is provided at the inner lower end of the cutting cutter body 2. The outer lower cutting surface 11 cooperates with the inner lower cutting surface 21 to achieve effective cutting of the soil layer, thereby reducing the cutting effect on soil layers of different depths by increasing the contact pressure with the soil layer.

[0029] like Figure 3As shown, a driving disc 4 for driving rotation is provided at the top of the spiral cutter body 1, and a positioning shaft column 5 is detachably connected at the axis of the driving disc 4. The bottom height of the positioning shaft column 5 is lower than the bottom height of the spiral cutter body 1. Therefore, when the soil layer is cut to achieve an effective extraction depth that is consistent with the actual soil layer, the positioning shaft column 5 is in contact with the surface of the soil layer to achieve the positioning function, and then the spiral cutter body 1 is used to drive the cutting cutter body 2 and the positioning shaft column 5 to perform synchronous rotational motion, so that the spiral cutter body 1, the cutting cutter body 2 and the positioning shaft column 5 can perform synchronous linear movement, and then a complete soil layer structure with consistent depth is obtained.

[0030] In the second embodiment of the present application, the engineering sampling device is a large-scale mobile sampling device, and a polygonal connecting column 51 is provided at the top of the positioning shaft column 5. The polygonal connecting column 51 and the driving disk 4 form a spiral driving member, and are used to be externally connected to the output device to achieve the purpose of driving rotation. In order to prevent the positioning shaft column 5 from penetrating deep into the soil layer and affecting the diffusion of the soil layer to the outside of the positioning shaft column 5 and affecting the structure of the soil layers at different depths, a discharge hole 52 is provided in the positioning shaft column 5. The discharge hole 52 is connected to the exhaust holes distributed in the radial direction, and the discharge hole 52 is used to discharge the soil layer structure located at the positioning shaft column 5, so as to improve the sampling efficiency and the sampling accuracy of the soil layers at different depths.

[0031] At the same time, the cutting drive member is a driving ring body 6 located at the top of the driving disk 4. The bottom of the driving ring body 6 penetrates the driving disk 4 from top to bottom and is used to drive the cutting blade 2 to move downward. Among them, a cutting capsule 7 is arranged at the bottom of the driving disk 4. A lower driving plate 71 is arranged at the bottom of the cutting capsule 7 for relatively upward and downward sealing movement, and the lower driving plate 71 is connected to the cutting capsule 7 by a flexible sealing material such as rubber, and the lower driving plate 71 is connected and fixed to the bottom of the driving ring body 6. It should be mentioned that a capsule cavity 72 filled with liquid is arranged in the cutting capsule 7, and an elastic body for pushing the lower driving plate 71 downward is arranged in the capsule cavity 72. The top of the cutting blade 2 is detachably connected to the plug-in portion 73 plugged into the cutting capsule 7, and the plug-in portion 73 is sealed and slidably connected to the cutting capsule 7 to avoid the liquid in the capsule cavity 72 from overflowing and has the purpose of pushing the cutting blade 2 downward through the liquid in the capsule cavity 72 to achieve the purpose of cutting the corresponding depth of the soil layer. The liquid can be oil, etc., which will not be repeated here.

[0032] When the lower driving plate 71 moves upward, the cutting blade 2 descends and forms a gap between the lower driving plate 71 and the topmost soil layer, which has the effect of forming negative pressure and adsorbing the soil layer, and thus effectively prevents the soil layer from falling off from between the spiral blade 1 and the cutting blade 2 of the engineering sampling device due to gravity. After the engineering sampling device is taken out of the soil layer, the lower driving plate 71 and the cutting blade 2 are reset, which will expose the soil layer between the blade gaps 3, so as to be used for direct sampling and detection of soil layers at different depths, thereby significantly improving the sampling and detection accuracy of soil layers at different depths.

[0033] Among them, a lifter 61 is arranged on the top of the driving disk 4, and the lifter 61 is used to drive the driving ring body 6 to make a linear movement toward or away from the driving disk 4, so as to achieve the purpose of automatically driving the cutting blade 2. At the same time, a driving motor 8 is detachably connected to the top of the positioning shaft column 5, and the driving motor 8 is connected to a fixed frame. The fixed frame plays the role of supporting and connecting the driving motor 8, and the fixed frame includes a supporting base plate 9. The middle part of the supporting base plate 9 is penetrated from top to bottom by the spiral cutter body 1, and a gap is formed for scraping off the outer soil layer, and the gap is controlled to be 1-3cm. Two brackets 91 symmetrically distributed on the upper side of the supporting base plate 9 are arranged, and the driving motor 8 is connected to the bracket 91 in an up-and-down sliding manner. Among them, a lifting limit groove 92 distributed in the vertical direction is arranged on the inner side of the bracket 91. A hoisting rod 81 is detachably connected to the top of the driving motor 8. The two ends of the hoisting rod 81 are matched with the corresponding lifting limit grooves 92 respectively. A fixed locking rod 93 is provided at the top of the support base plate 9, and the two ends are respectively connected and fixed to the top of the corresponding bracket 91, and the fixed locking rod 93 is used to be detachably connected with the hanging rod 81. Therefore, when using the engineering sampling device in the second embodiment of the present application, the support base plate 9 of the engineering sampling device is placed at the position of soil layer sampling, and the fixed locking rod 93 is connected and fixed with the hanging rod 81 to prevent the driving motor 8 from falling. In the second embodiment of the present application, the fixed locking rod 93 and the hanging rod 81 are connected by a vertical bolt thread, and then when the bolt is loosened, the hanging rod 81 will drive the driving motor 8, the spiral cutter body 1 and the cutting cutter body 2 to descend until the spiral cutter body 1 contacts the surface of the soil layer, and then the fixed locking rod 93 and the hanging rod 81 are separated. Then, the spiral cutter body 1 is driven by the driving motor 8 to be spirally inserted into the soil layer to effectively cut the soil layer of the corresponding depth, so as to achieve the purpose of convenient use, fast cutting and high-precision cutting.

[0034] In summary, the present application provides an engineering sampling device, which first uses a spiral drive to drive the spiral blade 1 and the cutting blade 2 to rotate synchronously in a spiral manner, and then inserts the spiral blade 1 and the cutting blade 2 into the corresponding depth inside the soil layer, and then the cutting drive drives the cutting blade 2 to perform an axial downward movement, so that the soil layer located between two adjacent spiral blade bodies 1 is cut by the cutting blade 2 whose width is greater than the width of the blade body interval 3, thereby effectively separating and cutting to form a soil layer structure of corresponding depth, so as to achieve the effect of accurately measuring the soil layer of corresponding depth after the soil layer is taken out.
