Description

Technical Field

[0001] This utility model relates to the technical field of soil and rock sampling devices, and in particular to a portable soil and rock sampling device. Background Technology

[0002] A soil and rock sampling device is a tool or equipment used to collect geological samples such as rocks and soil. It is widely used in geological exploration, civil engineering, environmental monitoring and other fields. A portable soil and rock sampling device consists of a rod, a handle and a drill bit.

[0003] Existing technologies, such as the utility model patent with publication number CN222258784U, disclose a soil and rock sampling device. This patent includes a frame, a drilling section rotatably mounted on a lifting mechanism, and the lifting mechanism driving the drilling section to move up and down on the frame. A drive unit drives the drilling section to rotate on the lifting mechanism and drill into the soil and rock. A collection section is mounted on the drilling section and moves with it. A gate is located on the collection section, used to allow for opening and closing of the collection section to the outside environment. When the drive unit drives the drilling section to rotate, the collection section is open to the outside environment; when the drive unit stops, the collection section is closed to the outside environment. The gate can block the collection section, preventing soil and rock from leaking out, thus reducing the need for multiple soil and rock samplings and improving sampling efficiency. By setting up a lifting mechanism, the length of the collection section extending to the outer shell can be fixed during sampling, and after sampling contact, the collection section can be retracted into the frame, making it smaller in size during movement and thus more convenient. (ESM) A similar invention has been applied for a patent on the same day.

[0004] The inventors discovered the following problems in the use of the portable soil and rock sampling device during their daily work: the rod and drill bit are integrated, and when users select the appropriate inner diameter and depth of the drill bit according to their sampling needs, the entire device needs to be replaced, which is costly and inefficient.

[0015] The above-mentioned components achieve the following effect: by using clamps to simultaneously hold and limit the anti-slip sleeves on both grips, the anti-slip sleeves will not loosen or fall off the grips after long-term use. The operation is simple and convenient, and it is easy for users to replace them later.

[0016] Preferably, the lower surface of the clamp plate has a plurality of anti-slip patterns on the position corresponding to the grip, and the plurality of anti-slip patterns are evenly distributed at both ends of the clamp plate.

[0017] The effect achieved by the above components is to increase the friction on the lower surface of the clamping plate through the anti-slip texture, thereby improving the clamping plate's limiting effect.

[0032] Reference Figures 2 to 4As shown in this embodiment: the adjustment structure 5 includes a mounting frame 501, which is fixedly connected to the rod 1. A mounting block 502 is slidably connected to the inner wall of the mounting frame 501. The lower surface of the mounting block 502 is fixedly connected to the drill bit 3. A positioning hole 503 is opened on the surface of the mounting block 502. A fixing plate 504 is fixedly connected to the upper surface of the mounting frame 501. Two round rods 505 are slidably connected to the inner wall of the fixing plate 504. Springs 506 are sleeved on the arc surfaces of the two round rods 505. The two ends of the springs 506 are fixedly connected to the round rods 505 and the fixing plate 504, respectively. A connecting plate 507 is fixedly connected to one end of the two round rods 505. A positioning rod 509 is fixedly connected to the side of the connecting plate 507 near the mounting frame 501. The arc surface of the positioning rod 509 is slidably connected to the mounting frame 501. The inner surface of the positioning hole 503 is... The wall and positioning rod 509 are slidably connected. The operating connecting plate 507 can easily release the limiting position of the mounting block 502 by the mounting frame 501, making it convenient for the user to change the drill bit 3 with the appropriate inner diameter and depth according to the needs, thus improving work efficiency. A pull ring 508 is rotatably connected to the side of the connecting plate 507 away from the mounting frame 501. The operating pull ring 508 drives the connecting plate 507 to move, making it convenient for the user to move the connecting plate 507. Two protective covers 510 are fixedly connected to the upper surface of the mounting frame 501 at the position corresponding to the round rod 505. The protective covers 510 protect the spring 506 and the round rod 505, extending the service life of the spring 506. The end of the positioning rod 509 near the mounting frame 501 is arc-shaped, which makes it easy for the positioning rod 509 to slide into the positioning hole 503.

[0033] Reference Figure 5 As shown in this embodiment: the auxiliary structure 6 includes an auxiliary frame 61, which is fixedly connected to the rod 1. An auxiliary rod 62 is rotatably connected to the top side of the inner wall of the auxiliary frame 61. A clamping plate 63 is threadedly connected to the arc surface of the auxiliary rod 62. The clamping plate 63 is slidably connected to the inner wall of the auxiliary frame 61. Anti-slip sleeves 64 are slidably connected to the arc surfaces of the two grips 2. The clamping plate 63 simultaneously clamps and limits the anti-slip sleeves 64 on the two grips 2, preventing the anti-slip sleeves 64 from loosening and falling off the grips 2 after long-term use. The operation is simple. The design is simple and convenient for users to replace later. Several anti-slip textures 65 are provided on the lower surface of the clamp plate 63 corresponding to the grip 2. The anti-slip textures 65 are evenly distributed at both ends of the clamp plate 63.

[0034] Detailed Instructions for Use: By adjusting the adjustment structure 5, first move the connecting plate 507 away from the mounting frame 501. The connecting plate 507 drives the two round rods 505 and the positioning rod 509 to move. When the round rods 505 move along the fixed plate 504, the spring 506 is compressed. The positioning rod 509 slides away from the positioning hole 503 along the mounting frame 501, releasing the restriction on the mounting block 502. At this time, the drill bit 3 can be moved downwards. The drill bit 3 drives the mounting block 502 to slide downwards away from the mounting frame 501. Take a drill bit 3 of appropriate diameter and length, and operate the new drill bit 3 from top to bottom towards the mounting frame 501, so that the mounting block 502 slides into the mounting frame 501. Release the connecting plate 507. 07. In the compressed state, the spring 506 provides a spring force to the round rod 505, causing the round rod 505 to move the connecting plate 507 towards the mounting frame 501. The connecting plate 507 then causes the positioning rod 509 to slide into the positioning hole 503 on the mounting block 502, thus fixing the positions of the mounting block 502 and the drill bit 3. The operating pull ring 508 moves the connecting plate 507, making it easy for the user to move the connecting plate 507. The protective cover 510 protects the spring 506 and the round rod 505, extending the service life of the spring 506. The end of the positioning rod 509 near the mounting frame 501 is arc-shaped, making it easy for the positioning rod 509 to slide into the positioning hole 503.

[0035] By setting the auxiliary structure 6, first rotate the auxiliary rod 62. The auxiliary rod 62 drives the clamping plate 63 to move upward along the inner wall of the auxiliary frame 61 with the help of the thread. After the clamping plate 63 moves away from the handle 2 by a certain distance, the anti-slip sleeve 64 is moved and put on the handle 2. Then rotate the auxiliary rod 62 in the opposite direction. The auxiliary rod 62 drives the clamping plate 63 to move downward with the thread. The clamping plate 63 moves downward and closes to the handle 2. The two ends of the clamping plate 63 squeeze and limit the anti-slip sleeve 64 on the two handles 2, so that the position of the anti-slip sleeve 64 is fixed. Among them, the anti-slip texture 65 increases the friction of the lower surface of the clamping plate 63 and improves the limiting effect of the clamping plate 63. The sliding rod 66 further limits the clamping plate 63, making the clamping plate 63 more stable when moving along the auxiliary frame 61.
