[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0028] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0029] In the above description of the present invention, it should be noted that the terms "one side" and "the other side" and the like indicate positions or locations based on the positions or locations shown in the accompanying drawings, or the positions or locations in which the product of the present invention is typically placed when in use. These terms are intended solely to facilitate the description of the present invention and simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0030] Furthermore, the term "identical" and similar terms do not necessarily require that the components be absolutely identical; slight variations are permitted. The term "perpendicular" simply refers to the positional relationship between components being more perpendicular than "parallel," not that the structure must be perfectly vertical; rather, it can be slightly tilted.

[0031] See also Figure 1-5 The utility model provides a technical solution: a coalfield geological survey sampling device, including a coalfield geological sampling tube 1, the outer surface of the coalfield geological sampling tube 1 is fixedly connected to a support 2, the support 2 is connected to a support rod 3 for damping rotation, and a pressure plate 4 is provided at one end of the support rod 3.

[0032] The damped rotation connection can be achieved by using a damped rotating shaft, so that the support rod 3 can have damped rotation. In this application, a groove is provided in the support 2, which can provide a fulcrum for damped rotation for one end of the support rod 3. The setting of the groove can limit the rotation angle of the support rod 3, and the rotation angle is 0-90 degrees. By unfolding the pressure plate 4 on the support rod 3 to a near horizontal state and pressing it to the ground, people can step on the pressure plate 4, so that the pressure plate 4 can limit the location of the coalfield sampling tube 1 through the support rod 3. By improving the stability of the coalfield geological sampling tube 1 on the ground, subsequent manual work can be used to knock the steel drill guided and limited in the coalfield geological sampling tube 1 deep into the stratum.

[0033] In this embodiment, a reduction groove 10 is provided on the coalfield geological sampling tube 1 .

[0034] The weight-reducing groove 10 can reduce the weight of the entire sampling device.

[0035] In this embodiment, a rotating plate 11 is fixedly connected to the pressing plate 4 , and the rotating plate 11 is connected to the support rod 3 in a damped rotation manner.

[0036] The connection of the damped rotation of the rotating plate 11 is also realized through the damping shaft. The rotation setting of the rotating plate 11 can make the pressure plate 4 have damping folding properties. In this application, one end of the support rod 3 is provided with a groove that provides a fulcrum for the damping shaft. The groove can rotate the rotation angle of the plate 11, and the rotation angle is 0-135 degrees.

[0037] In this embodiment, a cone head 6 is fixedly connected to the bottom of the pressing plate 4 .

[0038] There are multiple cone heads 6. When a person steps on the pressure plate 4, the cone heads 6 can extend into the ground, which can provide better locking performance for the support of the coalfield geological sampling tube 1.

[0039] In this embodiment: a locking structure 5 is provided on the support rod 3 and the coalfield geological sampling tube 1, and the locking structure 5 includes an elastic rope 51, which is fixedly connected to the coalfield geological sampling tube 1, and one end of the elastic rope 51 is fixedly connected to a hook ring 52, and the support rod 3 is fixedly connected to a hanging ear 53 for hooking the hook ring 52.

[0040] When in use, the support rod 3 is rotated and folded upward until the ear 53 is close to the hook ring 52, and the elastic material of the elastic rope 51 is used to pull the hook ring 52 to hook it on the ear 53. In this way, the support rod 3 stored on the coalfield geological sampling tube 1 can be locked, so that the subsequent coalfield geological survey sampling device can be moved and carried.

[0041] After the pressing plate 4 is folded, the cone head 6 is arranged outward. In order to prevent the cone head 6 from causing scratches to people, the direction of the cone head 6 can be adjusted by using the rotating plate 11 with damping rotation.

[0042] In this embodiment: a steel drill guide assembly 7 for limiting the steel drill is provided in the coalfield geological sampling tube 1. The number of the steel drill guide assembly 7 is a pair. The steel drill guide assembly 7 includes a V-shaped bracket 71. The V-shaped bracket 71 is fixedly connected to the inner wall of the coalfield geological sampling tube 1. The inner wall of the V-shaped bracket 71 is rotatably connected to a pair of rollers 72, and the rollers 72 are in rolling cooperation with the steel drill.

[0043] Roller 1 72 is partially embedded and arranged on the V-shaped bracket 71 through the coordinated rotation of the rotating shaft and the bearing. The V-shaped structure of the V-shaped bracket 71 can increase the limiting range of the sampling steel chisel of the columnar structure, and roller 1 72 can provide a sliding guide for the sampling steel chisel, so that the sampling steel chisel can be more smooth and stable when it is lowered by being struck by a hammer.

[0044] In this embodiment: the number of the steel drill guide assembly 2 9 is a pair, and the steel drill guide assembly 2 9 includes a limit plate 91, which is located above the V-shaped bracket 71, and the side of the limit plate 91 is rotatably connected to a roller 2 92, which cooperates with the steel drill.

[0045] A pair of steel drill guide assemblies 1 7 and a pair of steel drill guide assemblies 2 9 are distributed in pairs in the coalfield geological sampling tube 1. The setting of the limit plate 91 can adjust the diameter of the V-shaped bracket 71, and the roller 2 92 and the roller 1 72 have the same structure and principle. When the sampling steel drill is set between the V-shaped bracket 71 and the limit plate 91, at the same time, the roller 2 92 and the roller 1 72 roll in contact with the sampling steel drill. At this time, no manual support is required. The tail of the steel drill is hit by a hammer to allow the steel drill to steadily descend under the guidance of the roller 2 92 and the roller 1 72. The steel drill can break the ground, thereby allowing sampling of the coalfield geological soil layer.

[0046] In this embodiment: the linear drive structure 8 includes a precision screw 81, which is threadedly connected to the coalfield geological sampling tube 1. One end of the precision screw 81 is rotatably connected to a push plate 82, and the side of the push plate 82 is fixedly connected to a light rod 83. The light rod 83 slides through the coalfield geological sampling tube 1, and the limit plate 91 is fixedly connected to the push plate 82.

[0047] When in use, by rotating the precision screw 81, a rotating block can be set at one end of the precision screw 81 facing away from the push plate 82, and one end of the precision screw 81 can be rotatably connected to the push plate 82 through a bearing. The precision screw 81 can be moved by rotating the thread on the coalfield geological sampling tube 1, and cooperates with the light rod 83 to provide a sliding guide for the movement of the push plate 82, so that the push plate 82 can move horizontally in a straight line, and the position of the limit plate 91 can be adjusted by the horizontal movement of the push plate 82, so as to flexibly adjust the size of the limiting triangle space between the V-shaped bracket 71 and the limit plate 91, so that steel drills of different diameters can be used for guiding and limiting, which can meet the operational requirements of coalfield geological survey and sampling.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
