Description

Technical Field

[0001] The present invention belongs to the technical field of sampling devices, and particularly relates to a geological exploration sampling device. Background Art

[0002] Geological exploration refers to the work of investigating and researching geological conditions within a certain area by using various geological survey methods and technical means to obtain geological information and identify geological conditions such as mineral resources, geological structures, and stratigraphic lithologies.

[0003] The existing geological exploration operation is to use a sampling device to drill and sample at the location to be explored, so as to obtain the distribution of geological layers. When using the sampling device to drill into the rock formation, since the drill barrel lacks a suitable cutting-off device, after the drill barrel drills to the specified depth in the rock formation, due to the bottom end of the drill barrel not being able to perform a good cutting-off operation on the rock formation, and because the bottom end of the sample in the drill barrel is prone to adhesion to the rock formation, when the drill barrel drives the sample out of the drill hole, the bottom end of the sample is prone to fracture, thereby affecting the integrity of the sample.

[0004] Therefore, it is very necessary to invent a geological exploration sampling device to solve the above problems. Summary of the Invention

[0005] In view of the above problems, the present invention provides a geological exploration sampling device to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: A geological exploration sampling device includes a drill barrel. A plurality of vertical chutes are annularly distributed on the side wall of the drill barrel.

A circular groove is formed in the middle of the top of the pressing plate, and the electric push rod is vertically and fixedly connected between the inner wall of the bottom of the groove and the inner wall of the top of the drill barrel.

[0009] Further, a vertical installation groove is formed in the side of the extrusion rod close to the axis of the drill barrel. A separation assembly is installed in the installation groove.

The number of the insertion rods is two, and the two insertion rods are respectively fixedly connected to the two ends of the movable strip. The two insertion rods are respectively slidably inserted into the top and bottom groove walls of the installation groove. The return spring is fixedly connected to the bottom end of the insertion rod at the bottom, and the bottom end of the return spring is fixedly connected to the inside of the extrusion rod. The convex block is fixedly connected to the side of the insertion rod at the top close to the axis of the drill barrel. The pressing block is located directly above the convex block, and the pressing block is fixedly connected to the bottom of the pressing plate.

[0010] Further, a vibration assembly is arranged in the groove. The vibration assembly includes a rotating ring, fixed rods, guide rollers, knocking balls, deflection springs and vibrating rods. The rotating ring is rotatably installed on the side wall of the groove. A plurality of inclined guide holes are formed through the side wall of the rotating ring, and the plurality of guide holes are rotationally symmetric about the axis of the rotating ring. The number of the fixed rods is multiple, and the multiple fixed rods are directly opposite to the multiple guide holes.

In the present invention, by providing a knocking ball and a vibrating rod, when the pressing plate moves up and down under the action of the electric push rod, the rotating ring can drive the knocking ball to hit the vibrating rod under the cooperation of the guiding roller and the guiding hole, so that the rock sample located inside the drill cylinder can more easily fall out of the drill cylinder under the action of vibration. In addition, the generated vibration can also separate some of the rock samples adhered to the inner wall of the drill cylinder from the inner wall of the drill cylinder, reducing the probability of the rock samples remaining on the inner wall of the drill cylinder.

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments

[0031] The present invention provides a geological exploration sampling device as shown in Figures 1 to 9 , including a drill pipe 1. A plurality of vertical chutes are annularly distributed on the side wall of the drill pipe 1. The bottom ends of the chutes are inclined towards the direction close to the axis of the drill pipe 1, and a cutting assembly is installed in the chutes. The cutting assembly includes an extrusion rod 2, a connecting block 3, a cutting head 4, a compression spring 5, a guide block 6 and a power assembly. The top of the drill pipe 1 is fixedly connected with a connecting sleeve 24, and a connecting pin hole is penetrated through the side wall of the connecting sleeve 24

[0032] The extrusion rod 2 is slidably installed in the chute. The connecting block 3 is hinged to the bottom end of the extrusion rod 2. The cutting head 4 is slidably inserted at the bottom of the connecting block 3. The two sides of the cutting head 4 are flush with the two sides of the connecting block 3. The bottom of the cutting head 4 is designed with an inclined surface, and the bottom of the cutting head 4 is parallel to the inclined surface at the bottom of the chute. The compression spring 5 is fixedly connected between the top of the cutting head 4 and the inside of the connecting block 3. The number of the guiding blocks 6 is two. The two guiding blocks 6 are respectively fixedly connected to the two sides of the cutting head 4. Guiding grooves 7 are respectively formed at positions on both sides of the chute opposite to the guiding blocks 6. The guiding blocks 6 are slidably installed in the guiding grooves 7, and the bottom end of the guiding groove 7 inclines towards the direction close to the axis of the drilling cylinder 1. In the initial state, the cutting head 4 can be completely retracted into the chute. When the guiding block 6 moves to the bottom end of the guiding groove 7, the bottom end of the cutting head 4 can extend out of the chute, and the length that the cutting head 4 extends out of the chute is equal to the maximum expansion and contraction amount of the compression spring 5.

[0033] The power assembly includes a pressing plate 8, an electric push rod 9, a limiting rod 10 and a limiting spring 11. Vertical limiting grooves with the same number as the extrusion rods 2 are formed on the side surface of the pressing plate 8, and the multiple limiting grooves are respectively opposite to the multiple extrusion rods 2 one by one. The top end of the extrusion rod 2 protrudes towards the direction where the limiting groove is located, and the protruding part at the top end of the extrusion rod 2 is slidably installed in the limiting groove. The limiting rod 10 is vertically and fixedly connected to the inner walls of the top and bottom of the limiting groove, and the limiting rod 10 vertically slides through and is inserted on the extrusion rod 2. The limiting spring 11 is sleeved on the limiting rod 10, and the two ends of the limiting spring 11 are respectively fixedly connected to the top end of the extrusion rod 2 and the inner wall of the top of the limiting groove. A circular groove is formed in the middle of the top of the pressing plate 8. The electric push rod 9 is vertically and fixedly connected between the inner wall of the bottom of the groove and the inner wall of the top of the drilling cylinder 1. The elastic force of the limiting spring 11 is greater than the elastic force of the compression spring 5, and the maximum compression amount of the limiting spring 11 is greater than the distance from the bottom of the pressing block 16 to the top of the convex block 15 in the initial state.

[0034] Before sampling, first connect the drill barrel 1 to the output rotating shaft of the sampling machine through the connecting sleeve 24. Then move the drill barrel 1 to the area to be sampled. Finally, start the output rotating shaft on the sampling machine to drive the drill barrel 1 to gradually drill into the rock formation. During this process, the electric push rod 9 can remain in a contracted state, and the cutting head 4 can be retracted into the chute. As the sampling operation progresses, when the drill barrel 1 drills to the specified depth, start the electric push rod 9 to drive the pressing plate 8 to move downward. As the pressing plate 8 moves downward, the limiting spring 11 can press the extrusion rod 2 downward. As the extrusion rod 2 moves downward, the extrusion rod 2 can press the cutting head 4 downward through the connecting block 3. When the bottom of the cutting head 4 contacts the inclined surface at the bottom of the chute, the cutting head 4 can cooperate with the guiding groove 7 under the guiding action of the chute bottom wall and the limiting action of the guiding block 6, so that the bottom end of the cutting head 4 gradually deflects outward from the chute. When the cutting head 4 contacts the rock formation, the cutting head 4 can first compress the pressing spring 5 under the action of the blocking force of the rock formation on it, and the cutting head 4 can keep close to the surface of the sample inside the drill barrel 1 under the pressure of the pressing spring 5. At this time, as the drill barrel 1 continues to rotate, multiple cutting heads 4 can perform circular cutting along the surface of the sample under the action of the pressing spring 5. And as the cutting depth increases, the pressing spring 5 can gradually elongate. After the cutting head 4 cuts for a period of time, a circular cutting groove can be formed at the position of the bottom end of the sample. Subsequently, as the drill barrel 1 is taken out of the drill hole by the output rotating shaft of the sampling machine, the place where the bottom end of the sample is cut by the cutting head 4 can be easily broken off, thus ensuring the integrity of the sample in the drill barrel 1;

[0035] In addition, when the drill barrel 1 drives the sample inside it to move upward out of the drill hole, multiple cutting heads 4 can support at the edge position of the bottom end of the sample, so as to exert a limiting effect on the sample in the drill barrel 1, thereby avoiding the sample slipping out of the drill barrel 1 accidentally during the process of the drill barrel 1 being taken out of the drill hole. And when the drill barrel 1 is completely taken out of the drill hole, as the electric push rod 9 shortens, the pressing plate 8 can make the cutting head 4 gradually reset downward through the pulling force on the extrusion rod 2, so that the cutting head 4 can move away from the bottom edge position of the sample, avoiding blocking the extraction of the sample.

[0036] Such as Figures 2 to 9As shown in the figure, a vertical installation groove is formed on one side of the extrusion rod 2 close to the axis of the drill cylinder 1. A separation assembly is installed in the installation groove. The separation assembly includes a movable strip 12, a plug rod 13, a return spring 14, a convex block 15 and a pressing block 16. The movable strip 12 is slidably installed in the installation groove. The number of the plug rods 13 is two. The two plug rods 13 are respectively fixedly connected to both ends of the movable strip 12. The two plug rods 13 are respectively slidably inserted into the top and bottom groove walls of the installation groove. The return spring 14 is fixedly connected to the bottom end of the plug rod 13 at the bottom. The bottom end of the return spring 14 is fixedly connected to the inside of the extrusion rod 2. The convex block 15 is fixedly connected to one side of the plug rod 13 at the top close to the axis of the drill cylinder 1. The pressing block 16 is located directly above the convex block 15. The pressing block 16 is fixedly connected to the bottom of the pressing plate 8. One side of the movable strip 12 close to the axis of the drill cylinder 1 extends out of the limit groove, and horizontal anti-slip lines are uniformly arranged on one side of the movable strip 12 close to the axis of the drill cylinder 1;

[0037] By providing the separation assembly, when the drill cylinder 1 completes the drilling operation on the rock formation and is taken out of the drill hole, the rock sample located in the drill cylinder 1 may get stuck in the drill cylinder 1. At this time, by continuously extending the electric push rod 9, the pressing plate 8 can continue to move downward under the action of pressure. During this process, the limit spring 11 is further compressed, and the cutting head 4 can stop extending out of the sliding groove due to the limiting effect of the guiding groove 7 on it. As the pressing plate 8 continues to move downward, when the pressing block 16 at the bottom of the pressing plate 8 contacts the convex block 15 directly below it, as the pressing block 16 presses the convex block 15 downward, the convex block 15 can drive the movable strip 12 to move downward. During this process, the anti-slip lines on the surface of the movable strip 12 can slide downward along the outer edge of the sample, so as to apply a downward thrust to the sample through the friction force of the movable strip 12 on the sample, and further enable the sample stuck in the drill cylinder 1 to move downward under the action of this thrust. During the downward movement of the movable strip 12, the return spring 14 can be compressed by the plug rod 13 at the bottom. Since the elongation of the electric push rod 9 is limited, the electric push rod 9 can be repeatedly extended and retracted, so that the sample can be gradually pushed out from the bottom of the drill cylinder 1 through the repeated downward movement of the movable strip 12, thus avoiding the sample from getting stuck inside the drill cylinder 1 and ensuring the integrity of the sample when it is removed from the drill cylinder 1;

[0038] In addition, it should be noted that during the repeated telescoping of the electric push rod 9, although the cutting head 4 will initially extend out of the chute and press against the bottom edge position of the sample during the downward movement of the pressing plate 8, due to the presence of the compression spring 5, the cutting head 4 can contract a certain amount into the connecting block 3 under the extrusion of the sample. And when the bottom end of the sample extends to the bottom of the drill cylinder 1 under the action of its own gravity, as the pressing plate 8 moves downward and pushes the cutting head 4 downward through the extrusion rod 2, at this time, since the cutting head 4 is against the side of the sample, the cutting head 4 can compress the compression spring 5 under the blockage of the sample, so that the bottom end of the cutting head 4 can still be located in the chute, and thus will not block the sample during the subsequent downward movement of the movable bar 12 pushing the sample downward.

[0039] As Figures 2 to 6 shown, a vibration assembly is arranged in the groove. The vibration assembly includes a rotating ring 17, a fixing rod 18, a guide roller 19, a knocking ball 20, a deflection spring 21 and a vibration rod 22. The rotating ring 17 is rotatably installed on the side wall of the groove. A plurality of inclined guide holes 23 are formed through the side wall of the rotating ring 17, and the plurality of guide holes 23 are rotationally symmetric about the axis of the rotating ring 17. The number of the fixing rods 18 is multiple, and the multiple fixing rods 18 are in one-to-one correspondence with the multiple guide holes 23. The multiple fixing rods 18 are all vertically and fixedly connected to the inner wall of the top of the drill cylinder 1. The guide roller 19 is rotatably installed on one side of the fixing rod 18 close to the guide hole 23, and the guide roller 19 is slidably installed in the guide hole 23. The number of the deflection springs 21 and the vibration rods 22 is multiple. The multiple deflection springs 21 are uniformly and horizontally fixedly connected to the inner wall of the rotating ring 17. The knocking ball 20 is fixedly connected to the free end of the deflection spring 21. The vibration rod 22 is vertically and fixedly connected to the inner wall of the top of the drill cylinder 1, and the knocking ball 20 can contact the vibration rod 22;

[0040] By providing the knocking ball 20 and the vibration rod 22, when the pressing plate 8 moves up and down under the action of the electric push rod 9, the rotating ring 17 can also move up and down together with the pressing plate 8. During this process, the guide roller 19 can move up and down relative to the pressing plate 8 along the corresponding guide hole 23. With the relative movement of the guide roller 19, the guide roller 19 can make the rotating ring 17 rotate in the groove by the thrust on the inner wall of the guide hole 23. With the rotation of the rotating ring 17, the rotating ring 17 can drive the knocking ball 20 to collide with the vibration rod 22 in its moving direction through the deflection spring 21. With the knocking of the knocking ball 20 on the vibration rod 22, the vibration generated by the vibration rod 22 can be transmitted to the drill cylinder 1, so that the rock sample located inside the drill cylinder 1 can more easily fall out of the drill cylinder 1 under the action of the vibration. In addition, the generated vibration can also separate part of the rock sample adhered to the inner wall of the drill cylinder 1 from the inner wall of the drill cylinder 1, reducing the probability of the rock sample remaining on the inner wall of the drill cylinder 1.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
