Description

Technical Field

[0001] This invention relates to the field of geological exploration technology, and specifically to a soil and rock sampling device for geological exploration. Background Technology

[0002] The core working principle of soil and rock sampling equipment for geological exploration is to drive the drill bit sampler with power, and use mechanical action (static pressing, impact, rotary cutting) to overcome the resistance of the soil and rock mass, so that the target soil and rock mass can enter the sampling chamber and achieve complete collection of undisturbed or disturbed samples.

[0003] However, some existing geological exploration soil and rock sampling equipment lacks a quick-change structure for drill bits, which means that the drill bits cannot be quickly replaced when they are damaged by hard objects. In addition, the collected soil and rock lack a quick-discharge structure, making the sampling operation more cumbersome for staff. Summary of the Invention

[0004] The purpose of this invention is to provide a soil and rock sampling device for geological exploration, which can solve the problems of some soil and rock sampling devices for geological exploration lacking a quick drill bit replacement structure, resulting in the inability to quickly replace the drill bit when it is damaged by hard objects, and lacking a quick material unloading structure for the collected soil and rock, making the sampling operation more cumbersome for workers.

[0005] According to the technical solution provided by the present invention: a rock and soil sampling device for geological exploration includes a frame, a lift is slidably connected to the right side of the frame, a motor is fixedly connected to the top of the lift, a rotating shaft is fixedly connected to the output end of the motor, and a drill rod unit is sleeved on the outer wall of the rotating shaft.

[0006] The drill pipe unit includes a fixing component with a fixed connection function. Two sampling rods are slidably connected to the bottom surface of the fixing component. A limit component is slidably sleeved on the outer wall of the two sampling rods. A limit curved plate is slidably connected between the outer walls of the two sampling rods.

[0014] 1. Through the cooperation between the structures, the drill bit can be changed quickly by the workers. The limiting components and the internal structure of the fixing ring can speed up the removal of samples by the workers, thereby improving the working efficiency of this equipment.

Detailed Implementation

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0025] like Figure 1-6 As shown, the present invention is a soil and rock sampling device for geological exploration; it includes a frame 1, a lifting platform 2 slidably connected to the right side of the frame 1, a motor 4 fixedly connected to the top surface of the lifting platform 2, a rotating shaft 5 fixedly connected to the output end of the motor 4, and a drill rod unit 3 sleeved on the outer wall of the rotating shaft 5;

[0026] The drill rod unit 3 includes a fixing component 31 with a fixed connection function. Two sampling rods 32 are slidably connected to the bottom surface of the fixing component 31. A limiting component 33 is slidably sleeved on the outer wall of the two sampling rods 32. A limiting curved plate 35 is slidably connected between the outer walls of the two sampling rods 32. A drill bit 34 is connected between the bottom surfaces of the two sampling rods 32. Two fixing rings 37 are fixedly connected to the top surface of the drill bit 34. Two sets of sliders 38 are fixedly connected to the inner wall of the outer fixing rings 37. Two limiting plates 36 are fixedly connected to the bottom surface of the limiting curved plate 35. The limiting plates 36 are slidably connected to the fixing rings 37.

[0027] Specifically, when using this device, the frame 1 is pushed to move the device to the sampling position, the frame 1 is flipped so that the drill rod unit 3 is perpendicular to the bottom surface, the motor 4 is started, the motor 4 drives the drill rod unit 3 to rotate through the shaft 5, the lifting platform 2 is started, the lifting platform 2 drives the drill rod unit 3 to drill a hole in the bottom surface to sample through the motor 4, the motor 4 drives the sampling rod 32 to rotate through the fixed connection between the fixing component 31 and the limiting component 33, and the sampling rod 32 drives the fixed ring 37 to rotate to drill a hole in the bottom surface;

[0028] When the surface wear of the drill bit becomes severe after prolonged use, the bottom connecting structure of the sampling rod 32 can be removed by removing the limiting component 33. Then, the limiting curved plate 35 is pulled upward, causing the limiting plate 36 to separate from the fixed ring 37. The drill bit 34 can then be rotated clockwise, causing the fixed ring 37 and the slider 38 on the inner wall to rotate. Pulling the drill bit 34 downward separates it from the sampling rod 32, allowing for quick replacement. Similarly, after removing the limiting component 33 and separating the sampling rod 32 from the drill bit 34, the sampling rod 32 is separated from the limiting curved plate 35, allowing for quick removal of the samples stored inside the two sampling rods 32, thus completing the sampling process.

[0029] Preferably, the outer wall of the sampling rod 32 is provided with a sliding groove that matches the limiting plate 36 and the slider 38, and the outer wall of the sampling rod 32 is provided with a slot that matches the limiting curved plate 35.

[0030] Specifically, the groove on the outer wall of the sampling rod 32 allows the fixed ring 37 to be slidably connected to the sampling rod 32 via the slider 38 and then fixed by the limiting plate 36 without affecting the operation of the drill bit 34. By setting the slot on the outer wall of the sampling rod 32 to match the limiting curved plate 35, the limiting curved plate 35 can limit the distance between the two sampling rods 32 and enhance the power at the connection between the two sampling rods 32, so that the sampling rod 32 will not separate during rotation.

[0031] Preferably, the fixing component 31 includes a threaded sleeve 311 that is slidably sleeved on the outer wall of the rotating shaft 5. A hexagonal locking block 312 is fixedly connected to the top of the threaded sleeve 311, and the hexagonal locking block 312 is slidably connected to the rotating shaft 5. An inner threaded sleeve 313 is fixedly connected to the outer wall of the threaded sleeve 311 by threads. A limiting ring 314 is connected to the inner top surface of the inner threaded sleeve 313, and the limiting ring 314 is fixedly connected to the rotating shaft 5.

[0032] Specifically, multiple semi-circular clamping plates 331 are fixedly connected to both the outer wall of the threaded sleeve 311 and the outer wall of the sampling rod 32. These are then fitted together by the first clamping sleeve 332, followed by the clamping of the semi-cylinder 333 by the second clamping sleeve 334, and finally slidably fixed by the sliding cylinder 336. Through the interplay of these structures, the sliding cylinder 336 can be slid upwards when disassembly is required, separating it from the second clamping sleeve 334. Then, the second clamping sleeve 334 and the semi-cylinder 333 are separated to both sides. Finally, the first clamping sleeve 332 is separated from the semi-circular clamping plates 331, allowing for rapid disassembly of the limiting component 33 structure and separation of the sampling rod 32 structure, thereby improving the sampling efficiency of the staff.

[0033] Preferably, the limiting component 33 includes a semi-circular clamping plate 331 fixedly connected to the outer wall of the sampling rod 32 or the threaded sleeve 311, and the semi-circular clamping plate 331 is slidably connected to the threaded sleeve 311. Two first clamping sleeves 332 are sleeved on the outer wall of the threaded sleeve 311. The inner wall of the first clamping sleeve 332 is provided with a limiting groove that matches the semi-circular clamping plate 331. Two semi-cylinders 333 are fixedly connected to the outer wall of one side of the first clamping sleeve 332. Two adjacent semi-cylinders 333 form a cylinder. The outer walls of the two semi-cylinders 333 are slidably connected to the second clamping sleeve 334. The outer walls of the two second clamping sleeves 334 are slidably connected to the slide cylinder 336. The slide cylinder 336 is slidably connected to the inner threaded sleeve 313 or the second clamping sleeve 334.

[0034] Specifically, multiple semi-circular clamping plates 331 are fixedly connected to both the outer wall of the threaded sleeve 311 and the outer wall of the sampling rod 32. These are then fitted together by the first clamping sleeve 332, followed by the clamping of the semi-cylinder 333 by the second clamping sleeve 334, and finally slidably fixed by the sliding cylinder 336. Through the interplay of these structures, the sliding cylinder 336 can be slid upwards when disassembly is required, separating it from the second clamping sleeve 334. Then, the second clamping sleeve 334 and the semi-cylinder 333 are separated to both sides. Finally, the first clamping sleeve 332 is separated from the semi-circular clamping plates 331, allowing for rapid disassembly of the limiting component 33 structure and separation of the sampling rod 32 structure, thereby improving the sampling efficiency of the staff.

[0035] Preferably, the outer wall of the inner threaded sleeve 313 or the second ferrule 334 is fixedly connected with a limiting stripe 337, the inner wall of the slide cylinder 336 is provided with a curved groove that matches the limiting stripe 337, and the inner wall of the second ferrule 334 is provided with a groove 335 that matches the semi-cylinder 333.

[0036] Specifically, by setting the structure of the limiting stripe 337, the motor 4 will not slip due to the connection relationship when driving the semi-circular plate 331 to rotate through the rotating shaft 5, thus enhancing the connection effect between the threaded sleeve 311 and the rotating shaft 5. By setting the slot 335 to limit the semi-cylinders 333 on both sides, the tight fit between the first sleeve 332 and the threaded sleeve 311 is ensured.

[0037] Preferably, an elastic band 351 is connected between the sampling rod 32 and the limiting curved plate 35, and the side of the elastic band 351 is fixedly connected to the sampling rod 32 by glue.

[0038] Specifically, by setting the structure of the elastic band 351, after the sampling rod 32 is separated from the limiting curved plate 35 during disassembly, the elastic band 351 returns to its original shape due to its own elasticity, thereby preventing the groove on the surface of the sampling rod 32 from being covered by dirt and hindering its next use. The structure allows the slot on the sampling rod 32 to be used for a long time without frequent cleaning, thereby improving the sampling efficiency of the staff.

[0039] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
