Description

Technical Field

[0001] This utility model relates to the field of rock cuttings collection technology, and in particular to a drilling rock cuttings collection device. Background Technology

[0002] In geological drilling, mineral exploration, and geotechnical engineering investigation, it is necessary to systematically collect rock cuttings generated during the drilling process for geological logging and analysis. Sampling funnels are key tools used to receive and guide rock cuttings into sample bags.

[0003] Currently, sampling funnels typically consist of a conical cavity and a pipe fixedly welded to the bottom outlet. The outlet pipe is permanently fixed and exposed, making it impossible to store. This results in the entire device occupying a large space when not in use, having an irregular shape, and being very inconvenient to carry and store in a toolbox. During transportation, the exposed outlet pipe is easily bumped into other tools, causing deformation and damage to the pipe opening, or puncturing the sample bag and affecting its use. To address these issues, we propose a drilling cuttings collection device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drilling cuttings collection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A drilling cuttings collection device includes a conical cavity, an outlet pipe inserted at the bottom of the conical cavity, a connecting ring fixedly connected to the outer wall of the conical cavity, and a rectangular groove formed inside the connecting ring. A connecting block is inserted inside the rectangular groove, and a threaded groove is formed inside the connecting block. A threaded rod is inserted inside the threaded groove, and the threaded rod is inserted inside the connecting ring through a bearing. Two sets of limiting grooves adapted to the connecting block are formed inside the outlet pipe. A pinch plate is fixedly connected to the outer wall of the conical cavity.

[0006] Preferably, a limiting ring is fixedly connected to the top of the outlet pipe, and a groove adapted to the limiting ring is provided on the inner wall of the conical cavity.

[0007] Preferably, the inner wall of the rectangular groove is connected to a crossbar, and the inside of the connecting block is provided with a guide groove that matches the crossbar.

[0008] Preferably, a guide strip is fixedly connected to the outer wall of the outlet pipe, and a strip groove adapted to the guide strip is opened inside the conical cavity.

[0009] Preferably, a rotating plate is fixedly connected to the side of the threaded rod away from the connecting block, and the outer wall of the rotating plate is provided with anti-slip texture, and a protective pad is fixedly connected to the bottom end of the conical cavity.

[0010] Preferably, a fixing rod is fixedly connected to the top of the conical cavity, and a limiting piece is fixedly connected to the top of the fixing rod. A sealing plate is movably sleeved on the outside of the fixing rod.

[0011] Preferably, a rubber sheet is glued to the bottom of the sealing plate, and the cross-sectional area of ​​the sealing plate is larger than the opening area at the top of the conical cavity.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By incorporating a connecting ring and a connecting block, this device can transform into a regular, truncated cone without protruding parts when not in use. This greatly reduces the storage volume, making it easier to pack and carry. It also effectively prevents deformation and damage to the outlet pipe during transportation due to bumps, thus extending the tool's service life.

[0013] 2. The device is equipped with a fixed rod and a sealing plate. When not in use, the sealing plate can be rotated to further protect the outlet pipe embedded in the conical cavity. When sampling is temporarily suspended, the sealing plate can be quickly rotated to close, preventing residual rock cuttings from the borehole from falling and polluting the environment, or preventing external debris from mixing into the incomplete sampling process.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-6 A drilling cuttings collection device includes a conical cavity 1, an outlet pipe 2 inserted at the bottom of the conical cavity 1, a connecting ring 3 fixedly connected to the outer wall of the conical cavity 1, and a rectangular groove opened inside the connecting ring 3. A connecting block 5 is inserted inside the rectangular groove, and a threaded groove is opened inside the connecting block 5. A threaded rod 4 is inserted inside the threaded groove, and the threaded rod 4 is inserted inside the connecting ring 3 through a bearing. Two sets of limiting grooves 15 adapted to the connecting block 5 are opened inside the outlet pipe 2. A pinch plate 14 is fixedly connected to the outer wall of the conical cavity 1.

[0018] Furthermore, refer to Figure 4 It can be seen that the top of the outlet pipe 2 is fixedly connected to the limiting ring 8, and the inner wall of the conical cavity 1 is provided with a groove that matches the limiting ring 8. By using the limiting ring 8 with a diameter larger than that of the outlet pipe 2 and the groove provided on the inner wall of the conical cavity 1, the outlet pipe 2 can be limited during the pulling process, thereby effectively ensuring the quick alignment of the connecting block 5 and the upper limiting groove 15, preventing it from being completely pulled out from the bottom of the conical cavity 1, which would require the operator to laboriously reinstall and align it. In addition, the specifications of the groove and the limiting ring 8 are compatible, thereby preventing the entry of drill cuttings.

[0019] Furthermore, refer to Figure 4 It can be seen that the inner wall of the rectangular groove is connected to a horizontal bar 7, and the inside of the connecting block 5 is provided with a guide groove that matches the horizontal bar 7. Through the setting of the guide groove and the horizontal bar 7, the connecting block 5 can move precisely in a preset direction.

[0020] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the outer wall of the outlet pipe 2 is fixedly connected with a guide strip 10, and the inside of the conical cavity 1 is provided with a strip groove that matches the guide strip 10. Through the setting of the guide strip 10, the outlet pipe 2 can be vertically guided to ensure that the positions of the two sets of limiting grooves 15 and the position of the connecting block 5 always correspond.

[0021] Furthermore, refer to Figure 4 and Figure 5 It can be seen that a rotating plate 6 is fixedly connected to the side of the threaded rod 4 away from the connecting block 5, and the outer wall of the rotating plate 6 is provided with anti-slip texture. A protective pad 9 is fixedly connected to the bottom end of the conical cavity 1. With the setting of the rotating plate 6 and the anti-slip texture, it is convenient for the staff to rotate the threaded rod 4 with ease and convenience. With the setting of the rubber protective pad 9, the bottom end of the conical cavity 1 can be protected.

[0022] Furthermore, refer to Figure 2 , Figure 3 and Figure 6 It can be seen that a fixing rod 11 is fixedly connected to the top of the conical cavity 1, and a limiting piece 12 is fixedly connected to the top of the fixing rod 11. A sealing plate 13 is movably sleeved on the outside of the fixing rod 11. By using the fixing rod 11 and the limiting piece 12 together, the rotation requirements of the sealing plate 13 can be met, thereby achieving the sealing of the opening above the conical cavity 1, so as to protect the outlet pipe 2 embedded in the conical cavity 1, and can also provide temporary sealing.

[0023] Furthermore, refer to Figure 6 It can be seen that a rubber plate is glued to the bottom of the sealing plate 13. The cross-sectional area of ​​the sealing plate 13 is larger than the opening area of ​​the top of the conical cavity 1. The rubber plate is not shown in the figure. By setting the rubber plate, the friction between it and the top wall of the conical cavity 1 can be effectively increased, which can prevent the sealing plate 13 from rotating easily. Since the cross-sectional area of ​​the sealing plate 13 is large, the sealing effect on the conical cavity 1 can be improved.

[0024] Working Principle: In use, the operator first rotates the rotating plate 6, causing the threaded rod 4 to rotate simultaneously. This allows the threaded rod 4 and the connecting block 5 to engage threadedly, so that the connecting block 5 is embedded in the rectangular groove inside the connecting ring 3 and pulled out from the limiting groove 15 at the bottom of the outlet pipe 2. Then, the operator can pull down the outlet pipe 2 to remove it from the conical cavity 1. When the limiting ring 8 and the groove on the inner wall of the conical cavity 1 abut, the position of the connecting block 5 corresponds to the position of the limiting groove 15 on the upper side of the outlet pipe 2. Then, the operator can reverse the rotation... The rotating plate 6 is moved so that the connecting block 5 can be embedded into the limiting groove 15 to limit the pull-out outlet pipe 2. Then, the operator can push the sealing plate 13 so that it rotates along the central axis of the fixing rod 11, thereby opening the top opening of the conical cavity 1. Then, the operator can put the outlet pipe 2 into the collection container and pour the drill cuttings into the interior of the conical cavity 1. When the collection operation is paused in the middle, the sealing plate 13 can be rotated to temporarily seal the top opening of the conical cavity 1 to ensure the safety of the sampling process. The above is the entire working principle of this utility model.
