Description

Technical Field

[0001] The utility model relates to the field of soil sampling, in particular to a geological exploration sampling device. Background Art

[0002] When conducting geological exploration, it is very necessary to take soil samples, because soil is the product of weathering of surface rocks, and its samples are easy to obtain. Using high-precision instruments to analyze soil samples can obtain highly representative and accurate results. The content and combination of soil elements are very similar to the original rock, mineral (mineralized) body, etc. By studying the geochemical properties of soil, geochemical anomalies related to the mineralization of the original rock can be discovered, which is of great significance for prospecting.

[0003] When sampling soil, special equipment is generally required for drilling and sampling. There are many types of such devices, but many of them are electric drilling methods. When conducting geological exploration outdoors, power supply is not convenient, so the use of electric methods is relatively limited. Moreover, when collecting soil samples, the soil has a certain viscosity and will stick to the inner wall of the sampling drill bit, making it difficult to remove a complete soil core column sample. Therefore, it is necessary to optimize and improve it. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of the utility model is to provide a geological prospecting sampling device.

[0005] The technical solution of the utility model is as follows: A geological prospecting sampling device, characterized in that it comprises:

[0006] A base, wherein a vertical sleeve is fixedly provided at the center of the base, and the inner peripheral wall of the sleeve is provided with threads;

[0007] A threaded tube, wherein the outer peripheral wall of the threaded tube is provided with threads, the threaded tube is inserted into the sleeve and is threadedly connected with the sleeve, and a plurality of handle rods arranged at intervals along the circumference of the threaded tube are fixedly provided on the top of the threaded tube;

[0008] A sampling drill bit, which is cylindrical and coaxially fixed to the bottom of the threaded tube;

[0009] A core stripping plug, which is arranged in the threaded tube and can move up and down along the threaded tube and the sampling drill bit, and a push-pull rod is fixedly arranged on the upper side of the core stripping plug, and the push-pull rod extends upward from the threaded tube;

[0010] An extension tube, the base is provided with a plurality of legs spaced apart along the circumference of the base, each of the legs is detachably mounted with the extension tube, and the extension tube is suitable for being sleeved on the handlebar.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. This device uses a pure mechanical screw-driven device to realize the mobile drilling of the sampling drill bit, so there is no need to consider the power supply problem, which is more convenient outdoors;

[0013] 2. This device is also equipped with an extension tube, which can be placed on the handlebar, which can increase the power arm during rotation and make rotation more labor-saving. If the extension tube is not needed, the extension tube can be stored and installed on the outrigger, which is very convenient and will not affect the normal operation of the device.

[0014] 3. A coring plug is provided in the threaded tube of the device. When the soil core column sample needs to be taken out, the coring plug is pressed downward by the push-pull rod, and the coring plug can gradually push out the soil core column sample.

[0027] like Figure 1-Figure 5 The geological prospecting sampling device shown comprises: a base 1, a threaded pipe 3, a sampling drill bit 5, a core stripping plug 6 and an extension pipe 8.

[0028] A vertical sleeve 2 is fixedly provided at the center of the base 1, and the inner circumferential wall of the sleeve 2 is provided with a thread; the outer circumferential wall of the threaded tube 3 is provided with a thread, the threaded tube 3 is inserted into the sleeve and is threadedly connected to the sleeve, and a plurality of handle rods 4 arranged at intervals along the circumference of the threaded tube 3 are fixedly provided on the top of the threaded tube 3; the sampling drill bit 5 is cylindrical and coaxially fixed to the bottom of the threaded tube 3; the core stripping plug 6 is arranged in the threaded tube 3 and can move up and down along the threaded tube 3 and the sampling drill bit, and a push-pull rod 7 is fixedly provided on the upper side of the core stripping plug 6, and the push-pull rod 7 extends upward from the threaded tube 3; the base 1 is provided with a plurality of legs 12 arranged at intervals along the circumference of the base 1, and each leg 12 is detachably mounted with an extension tube 8, and the extension tube 8 is suitable for being sleeved on the handle rod 4.

[0029] Specifically, in view of the inconvenient power supply during outdoor geological exploration, this device does not adopt electric drilling sampling, but adopts pure mechanical drilling sampling, so there is no need to consider power supply issues, and it is more convenient to use outdoors.

[0030] The device adopts a screw drive form to realize the mobile drilling of the sampling drill bit 5. When performing the sampling operation, the handle rod 4 is grasped, and then the screw tube 3 is rotated to drive the sampling drill bit 5 to move up and down, so that the sampling can be carried out deep into the soil and the soil sample can be taken out. This screw drive form is simple, easy to implement, and convenient to operate.

[0031] In order to save more effort when rotating the threaded tube 3, the device is also equipped with an extension tube 8, which can be placed on the handle bar 4, so that the power arm during rotation can be increased, making it more convenient for the staff to rotate the threaded tube 3. If the extension tube 8 is not needed, the extension tube 8 can be stored and installed on the support leg 12, which is very convenient and will not affect the normal operation of the device.

[0032] Then in further settings, such as Figure 2 and Figure 3 As shown, the leg 12 is provided with a plurality of elastic buckles 9 arranged at intervals along the length direction of the leg 12 , and the extension tube 8 is clamped on the buckles 9 , thereby facilitating the disassembly and assembly of the extension tube 8 .

[0033] Among them, the buckle 9 is a U-shaped buckle 9, the open end of the U-shaped buckle 9 is the clip-in end, the closed end of the U-shaped buckle 9 is fixedly connected to the support leg 12, the part of the U-shaped buckle 9 located between the open end and the closed end is an arc-shaped part 10, the arc-shaped part 10 is tightly fitted with the tube wall of the extension tube 8, and the edge of the open end is provided with a curling edge 11. This buckle 9 has a simple structure and is easy to use.

[0034] Because the soil has a certain viscosity when collecting soil samples, it will stick to the inner wall of the sampling drill bit 5, making it difficult to take out a complete soil core column sample. Therefore, the device is equipped with a coring plug in the threaded tube 3. When it is necessary to take out the soil core column sample, the coring plug is pressed downward by the push-pull rod 7, and the coring plug can gradually push out the soil core column sample. This coring method can ensure the integrity of the soil core column sample.

[0035] Furthermore, if Figure 5 As shown, the core removing plug 6 is provided with a plurality of micro air permeable holes 13 penetrating the core removing plug 6 along the thickness direction of the core removing plug 6. Therefore, when coring, if there is air between the core removing plug 6 and the soil core column sample, the air can be discharged from the air permeable holes 13, thereby preventing the air from being compressed by the core removing plug 6 and breaking the soil core column sample downward.

[0036] Furthermore, a push-pull plate 14 is fixedly provided on the top of the push-pull rod 7 , thereby facilitating manual pushing and pulling of the push-pull rod 7 .

[0037] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
