Description

Technical Field

[0001] This utility model relates to the field of environmental survey equipment technology, specifically to an inclined sampler. Background Technology

[0002] In the fields of environmental surveys and soil pollution monitoring, obtaining soil samples from specific areas is the core foundation for analyzing soil characteristics and assessing environmental quality.

[0003] Current mainstream vertical soil sampling technology has significant advantages under normal terrain conditions due to its convenient operation and mature technology. However, when it comes to special sensitive areas such as building foundations, municipal facilities, and seepage-proof landfills, traditional vertical sampling methods have significant technical defects. This is because vertical sampling requires surface drilling, which will directly damage the existing structures above the target area, requiring subsequent facility repair. To address this, an inclined sampler has been proposed. Utility Model Content

[0004] Based on the above description, this utility model provides an inclined sample sampler, which solves the technical problems pointed out in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A tilting sampler, comprising:

[0006] The frame includes a base, and side frames are provided on the upper surface of the base;

[0007] The upright has pivots fixed on its front and rear sides, and is rotatably connected to the side frame through the pivots;

[0008] An angle adjustment structure includes a transmission box installed on the outside of the side frame. A worm gear and a worm wheel are provided in the transmission box. The worm gear and the worm wheel are connected in a transmission manner. One end of the worm gear extends out from one side of the transmission box. One end of the rotating shaft passes through the outer wall of the transmission box and extends into the inside of the transmission box. The worm wheel is assembled on the outside of this rotating shaft.

[0009] The sampling structure is located on the left side of the column and includes a positioning plate. A threaded hole is provided on the positioning plate, and a screw is threaded into the threaded hole. A sampler is provided at the bottom end of the screw.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, there are two side frames, and the angle adjustment structure is fixed to the outside of either side frame by bolts.

[0012] Furthermore, each of the side frames has a waist hole coaxial with the rotating shaft on its front side. A positioning slide column is slidably connected in this waist hole. The positioning slide column is fixedly connected to the upright column. A pointer is fixed at the end of the positioning slide column away from the upright column. An angle scale is provided on the outer side of the side frame.

[0013] Furthermore, side plates are fixed on both the front and rear sides of the base, and through holes are provided on the side plates for driving in ground anchor bolts.

[0014] Furthermore, the left end of the worm gear one extends out from the left side of the transmission box and is fixed with a handle one for the operator to hold.

[0015] Furthermore, it also includes a lifting device structure, which includes a liftable box set on the outside of the column. A shaft is rotatably connected between the front and rear inner side walls of the box. A worm gear and a gear are fixed on the outside of the shaft in a front-to-back arrangement.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] by Figure 1 For example, B is a special sensitive area such as building foundation, municipal facilities, and seepage-proof landfill, and C is the target area that needs to be sampled. If direct vertical sampling is required, surface drilling operations need to be carried out in area B. This operation will directly damage the existing structure above the target area C that needs to be sampled. Here, the existing structure refers to area B. That is, vertical sampling will lead to the need for facility repair later.

[0030] Therefore, reduce or avoid facility repair costs, such as Figure 2-6 As shown in this embodiment, an inclined sampler is used for sampling soil or solid waste. It includes a frame 1, a column 2, an angle adjustment structure 3, and a sampling structure 4. The frame 1 is placed on the ground during use, and the column 2 is rotatably adjustable on the frame 1 and its angle is adjusted by the angle adjustment structure 3. The sampling structure 4 is a prior art technology and is connected to the column 2. When the angle of the column 2 changes, the angle of the sampling structure 4 can also change synchronously. Thus, when the angle of the sampling structure 4 changes, it will not cause drilling damage to area B, and will not lead to the need for facility repair in area B later.

[0031] The aforementioned frame 1 includes a base 11, which is erected on the ground during use. Side frames 12 are fixed on the upper surface of the base 11. There are two sets of side frames 12, which are spaced apart to allow the column 2 to be rotatably positioned between the two side frames 12. It is understood that anti-slip teeth can be welded to the bottom of the base 11 to enhance its anti-interference ability. In addition, in some embodiments, side plates are welded on both the front and rear sides of the base 11. Perforations are provided on the side plates, and ground anchors of the corresponding size in the prior art can be driven into the perforations. The ground anchors are not shown in the figure. This design is mainly used for soft ground. It should be noted that if ground anchors are used, they are mainly used for soft ground.

[0032] As for the column 2, it is rectangular when viewed from above, and there are rotating shafts 21 fixed on the front and rear sides of the column 2. The side frame 12 is provided with a rotating hole, and the rotating shaft 21 is adapted to rotate inside the rotating hole. That is, the column 2 is rotatably connected to the side frame 12 through the rotating shaft 21.

[0033] It should be noted that, in order to understand the angle adjustment situation, the preferred scheme is designed with a reference point. Specifically, each side frame 12 has a waist hole 13 on the front side, which is coaxial with the rotating shaft 21 to avoid interference. A positioning slide column 14 is slidably connected in this waist hole 13. The positioning slide column 14 is fixedly connected to the column 2. In this way, the positioning slide column 14 can change the same angle as the column 2. A pointer 15 is fixed at the end of the positioning slide column 14 away from the column 2. An angle scale is set on the opposite side of both sets of side frames 12. The cooperation of the angle scale and the pointer 15 provides a reference point, that is, the operator can know the specific angle adjustment situation, so as to adjust the correct tilt angle to match the stratum direction and accurately obtain the sampling of area C.

[0034] Angle adjustment structure 3 is used to control the angle adjustment of column 2. There is one set of them, which are installed on the outside of any side frame 12. The angle adjustment structure 3 includes a transmission box 31 fixed to the outside of the side frame 12 by bolts. A worm gear 32 and a worm wheel 33 are provided in the transmission box 31. The worm gear 32 and the worm wheel 33 are connected in a transmission. One end of the worm gear 32 extends out from one side of the transmission box 31 and is fixed with a handle for the operator to hold. One end of the rotating shaft 21 penetrates the outer wall of the transmission box 31 and extends into the inside of the transmission box 31. The worm wheel 33 is assembled on the outside of the rotating shaft 21.

[0035] With this design, rotating the handle 1 will drive the worm gear 32 to rotate the worm wheel 33, and the rotating shaft 21 will cause the column 2 and the sampling structure 4 to tilt, thereby matching the stratum direction and accurately obtaining samples from area C. Since there is no need to drill and damage area B, it will not require facility repair in area B later, reducing repair costs. In addition, the worm gear design has a self-locking function, ensuring that the angle will not regress when the worm gear 32 is not rotated.

[0036] The sampling structure 4 is located on the left side of the column 2 and includes a positioning plate 41. A threaded hole is provided on the positioning plate 41, and a screw 42 is threadedly connected in the threaded hole. A sampler 43 is provided at the bottom end of the screw 42. The sampler 43 is existing technology and consists of a sampling shovel and a sample tube. The sample tube is fixed at the bottom end of the screw 42, and a handwheel is fixed at the top end of the screw 42 for the operator to hold.

[0037] After the angle is adjusted, the sampling structure 4 is tilted. Turn the handwheel to raise and lower the screw 42, and the sampler 43 is driven into the soil until it reaches the target area C that needs to be sampled, and the sampling is completed.

[0038] In addition, to extend the stroke of the sampling structure 4, the inclined sample sampler also includes a lifting structure 5. The lifting structure 5 includes a box 51 that can be lifted and lowered and is located on the outside of the column 2. The positioning plate 41 is fixed on the outside of the box 51 to move synchronously with the box 51. A shaft 52 is rotatably connected between the front and rear inner side walls of the box 51. A worm gear 53 and a gear 54 distributed in the front and rear are fixed on the outside of the shaft 52. Multiple meshing teeth 55 are fixed on the outside of the column 2. The gear 54 is connected to the column 2 through the meshing teeth 55 to control the position of the box 51. A worm gear 56 is also rotatably assembled in the box 51. The worm gear 56 is connected to the worm gear 53. In addition, the right end of the worm gear 56 extends out from the right side of the box 51 and is fixed with a handle for the operator to hold.

[0039] With this design, rotating the second handle causes the second worm gear 56 to drive the second worm wheel 53 to rotate, which in turn drives the shaft 52 to rotate. The shaft 52 then drives the gear 54 to rotate. Since the gear 54 meshes with the column 2 through the meshing teeth 55, the housing 51 and the sampling structure 4 can be adjusted in height, thereby expanding the stroke of the sampling structure 4.

[0040] In summary, for example, if area B is a building site, the base 11 is anchored in a safe area next to the building foundation, and the angle of the column 2 is adjusted so that the sampler 43 can penetrate obliquely to the target area C that needs to be sampled, thus avoiding damage to area B.

[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
