Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, and in particular to a device for interchangeable diameters of a splitting sample device. Background Technology

[0002] During the mining process, especially for hard rocks such as granite, it is necessary to conduct experimental tests on the bottom or interior of the ore to confirm whether it meets the mining standards. Typically, a hollow drill is used to penetrate deep into the rock to take samples and drill columnar rock columns.

[0003] In existing technologies, the common practice is to cut the extracted columnar rock column into segments to obtain samples of different sizes for testing. Specifically, the columnar rock column sample is placed inside a limiting pipe, one end of which is then inserted into the inlet of a splitting device and secured. The splitting device is then used to split the rock column in half. Before cutting, the columnar rock column sample needs to be pushed inwards so that it is positioned below the cutting disc of the splitting device. However, the inlet size of the cutting device cannot be adjusted according to the diameter of the rock column. This means that only limiting pipes of the same size can be used to cut rock columns of a specific size, significantly reducing the flexibility of the splitting device. Summary of the Invention

A threaded groove is opened on the outer wall of the mounting column, and a locking nut is threadedly connected to the threaded groove. The locking nut abuts against the outer wall of the pressing plate.

[0011] To facilitate locking the limiting groove formed between the two sets of limiting blocks, the locking and fixing mechanism further includes a locking cylinder fixedly connected to the outer wall of the frame. A locking channel is provided inside the fixing block. A locking rod is slidably connected to the locking cylinder. One end of the locking rod extends into the locking channel and is provided with a locking plate. A locking protrusion is fixedly connected to the locking plate. At least two sets of equidistant limiting blocks are provided on the connecting rod. A limiting groove is formed between the two sets of limiting blocks. The locking protrusion cooperates with the limiting groove. A piston is provided at the other end of the locking rod. The piston is connected to the inner wall of the locking cylinder by a spring.

[0012] To facilitate the movement of the locking rod, preferably, a pressure box is provided on the top of the workbench, and a pressure rod is slidably connected to the pressure box. One end of the pressure rod extends into the cavity of the pressure box and is provided with a pressure plate.

The pressure plate is located below the cutting assembly.

[0013] Furthermore, a limit spring is provided at the bottom of the booster box, and the top of the limit spring is fixedly connected to the booster plate.

[0018] 2. The diameter interchange device of the splitting sample equipment moves towards the limiting groove formed between the two sets of limiting blocks by the locking protrusion on the locking plate and inserts into the limiting groove.

[0019] 3. The diameter interchange device of this splitting sample equipment, when the gas is delivered through the gas outlet pipe, will cause the annular hollow expansion air bag to expand rapidly and stick tightly to the outer wall of the columnar material, thereby effectively fixing the columnar material being cut and preventing it from shaking or shifting during the cutting process.

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] During mining operations, especially for high-hardness rocks such as granite, it is necessary to conduct pre-mining tests on the bottom or interior of the ore to confirm whether it meets mining standards. A common practice is to cut the extracted columnar rock into sections to obtain samples of different sizes for testing. The columnar rock sample is placed in a limiting pipe, and one end of the limiting pipe is inserted into the inlet of a splitting sample device. After fixing the limiting pipe, the splitting sample device is used to split the rock in half. Before cutting, the columnar rock sample needs to be pushed inward. A cutting component is also provided on worktable 1. It is also equipped with a notch 101. The cutting assembly includes a cutting arm 2 rotatably connected to the worktable 1. A drive motor 3 is fixedly connected to the cutting arm 2. The cutter head is fixedly connected to the output end of the drive motor 3. When the limiting pipe is inserted into the cutting channel on the worktable 1 through the frame 4, the cutter head on the cutting assembly can cover the entire cross section of the cutting channel through the stroke of the notch 101, so that it is located in the cutting channel. The drive motor 3 drives the cutter head to rotate, splitting the columnar rock column sample in half, so that the columnar rock column sample can be accurately divided into two parts for subsequent detailed testing and analysis.

[0033] Example:

[0034] Reference Figures 1-7 A slitting sample cutting device with interchangeable nozzle diameters includes a cutting channel on a workbench 1, extending along the length of the workbench 1. The cutting channel has an O-shaped cross-section to facilitate the insertion of a limiting pipe. A frame 4 is installed at the inlet of the cutting channel and is connected to the cutting channel. A limiting expansion structure is installed on the inner wall of the outlet of the cutting channel to flexibly support and limit the cutting columnar material. The cutter head does not affect the supporting effect of the limiting expansion structure. The frame 4 is connected to the cutting channel, and the channel of the frame 4 contains... The lifting mechanism includes a limit adjustment mechanism. The working end of the limit adjustment mechanism is equipped with three sets of circumferentially distributed limit components. The limit components abut against the outer wall of the limiting pipe. The limit adjustment mechanism includes a limit arc plate 7 that is lifted and installed in the channel of the frame 4. The inner wall of the limit arc plate 7 is equipped with at least two sets of circumferentially equidistant limit components. The limit components include a conical tip 701 and a cylindrical limit end 702. The design of the limit arc plate 7 can tightly fit the outer wall of the limiting pipe, ensuring that the limiting pipe remains stable during the splitting process, thereby improving the accuracy and safety of the splitting.

[0035] In the above scheme, when it is necessary to replace the limiting pipe with a different diameter, the staff only needs to adjust the position of the limiting arc plate 7 and fix the limiting pipe. In addition, the lifting setting of the limiting arc plate 7 also makes it easy for the staff to flexibly adjust the height of the limiting pipe according to actual needs, thereby further enhancing the applicability and flexibility of the splitting equipment.

[0036] In order to improve the limiting effect of the limiting arc plate 7 on the limiting pipe, the limiting component includes a tapered tip 701 provided on the inner wall of the limiting arc plate 7. The design of the tapered tip 701 enables it to form a tight fit with the outer wall of the limiting pipe, thereby greatly enhancing the fixing effect of the limiting arc plate 7 on the limiting pipe.

[0037] To improve the limiting effect of the limiting arc plate 7 on the limiting pipe, the limiting component may also include a cylindrical limiting end 702 disposed on the inner wall of the limiting arc plate 7. The design of the cylindrical limiting end 702 can further enhance the contact effect between the limiting arc plate 7 and the limiting pipe.

[0038] In the above scheme, the design of the limiting component ensures that the limiting arc plate 7 remains stable and is not prone to displacement even when subjected to large external forces during the splitting process.

[0039] A locking and fixing mechanism is also provided on the outer wall of the frame 4. The working end of the locking and fixing mechanism extends into the channel of the frame 4 and is provided with a locking element. The limit adjustment mechanism is provided with a protrusion that cooperates with the locking element. The design of the locking and fixing mechanism allows the locking element on the working end to cooperate tightly with the protrusion on the limit adjustment mechanism after the limit arc plate 7 is adjusted to the required position and the limit pipe is fixed. This achieves a stable lock on the limit arc plate 7.

[0040] A fixing block is set at the top of the frame 4, and a sliding groove is opened on the fixing block. A connecting rod 6 is slidably connected to the sliding groove. A pressing plate 601 is set at the top of the connecting rod 6. A limiting arc plate 7 is fixedly connected to the bottom of the connecting rod 6. The design of the pressing plate 601 facilitates the operation of raising and lowering the connecting rod 6, thereby realizing the adjustment of the position of the limiting arc plate 7. During the adjustment process, the connecting rod 6 can slide along the sliding groove, ensuring the smoothness and accuracy of the raising and lowering movement. In addition, there are two sets of symmetrically arranged connecting rods 6, ensuring that the limiting arc plate 7 can only be raised and lowered within the channel of the frame 4. Furthermore, the cooperation of the fixing block and the sliding groove makes the raising and lowering movement of the connecting rod 6 more stable and reliable, avoiding the situation where the limiting arc plate 7 shakes during the splitting process, which affects the splitting effect.

[0041] A mounting column 5 is fixedly connected to the frame 4. A pressing plate 601 is slidably connected to the mounting column 5 through a through hole 602. A threaded groove is provided on the outer wall of the mounting column 5, and a locking nut 501 is threadedly connected to the threaded groove. The locking nut 501 abuts against the outer wall of the pressing plate 601. After the operator adjusts the height of the limiting arc plate 7, they only need to rotate the locking nut 501 to make it fit tightly against the outer wall of the pressing plate 601, which will stabilize the connecting rod 6 and the limiting arc plate 7 in the current position. This locking mechanism is not only easy to operate, but also has a significant locking effect. It effectively prevents the limiting arc plate 7 from being displaced due to external force during the splitting process, ensuring the working stability and splitting accuracy of the splitting sample equipment. At the same time, the cooperation of the threaded groove and the locking nut 501 enables fine adjustment of the position of the pressing plate 601, further enhancing the practicality of the device. Furthermore, the frame 4 can be used to quickly replace and fix limiting pipes of different diameters to adapt to columnar rock samples of different sizes.

[0042] To improve the limiting effect of the limiting arc plate 7, the locking and fixing mechanism includes a locking cylinder 15 fixedly connected to the outer wall of the frame 4. A locking channel 401 is provided inside the fixing block. A locking rod 17 is slidably connected to the locking cylinder 15. One end of the locking rod 17 extends into the locking channel 401 and is provided with a locking plate 18. A locking protrusion 19 is fixedly connected to the locking plate 18. At least two sets of equidistant limiting blocks 8 are provided on the connecting rod 6. A limiting groove is formed between the two sets of limiting blocks 8. The locking protrusion 19 and the locking plate 19 are fixedly connected to the locking plate 401. The locking rod 17 is fitted with a piston 16 at the other end, and the piston 16 is connected to the inner wall of the locking cylinder 15 by a spring. When the locking rod 17 moves on the locking cylinder 15, the locking protrusion 19 on the locking plate 18 moves toward the limiting groove formed between the two sets of limiting blocks 8 and inserts into the limiting groove. Since the limiting blocks 8 are set at an angle, the locking protrusion 19 can cooperate with the limiting groove to limit the connection rod 6 during the insertion process, thus securing the connection rod 6 on the mounting post 5.

[0043] To facilitate the automatic insertion of the locking rod 17, a pressure box 9 is provided on the top of the workbench 1. A pressure rod 12 is slidably connected to the pressure box 9. One end of the pressure rod 12 extends into the cavity of the pressure box 9 and is provided with a pressure plate 10. The pressure plate 10 fits against the inner wall of the pressure box 9. The other end of the pressure rod 12 is provided with a pressure plate 13. The pressure plate 13 is located below the cutting arm 2. A limit spring 11 is provided at the bottom of the pressure box 9. The top of the limit spring 11 is fixedly connected to the pressure plate 10. Through the cooperation of the pressure plate 13 and the cutting arm 2, when the cutting arm 2 is rotated to cut the columnar raw material, the pressure plate 13 will be pressed, thereby transporting the gas below the pressure box 9 to the locking cylinder 15 through the air outlet pipe 20, and then pushing the piston 16 to drive the locking rod 17 to move, so as to achieve the effect of automatic locking.

[0044] The aforementioned limiting expansion structure includes an annular hollow expansion airbag 14 disposed on the inner wall of the cutting channel outlet. This airbag can be made of high-strength, high-elasticity rubber or silicone materials, which possess excellent sealing and wear resistance, ensuring the stability and durability of the annular hollow expansion airbag 14 during use. Simultaneously, these materials also possess a certain elastic recovery capability. Through the limiting spring 11 within the pressure box 9, the pressure plate 10 is reset, allowing the annular hollow expansion airbag 14 to quickly return to its original state after cutting, preparing for the next cut. The pressure box 9 is connected to the annular hollow expansion airbag 14 and the locking cylinder 15 via an air outlet pipe 20. When the gas is received from the pressurization box 9 and delivered through the outlet pipe 20, the annular hollow expansion airbag 14 will rapidly expand and adhere tightly to the outer wall of the columnar material, thereby effectively fixing the columnar material being cut and preventing it from shaking or shifting during the cutting process. This design not only improves the cutting accuracy and stability but also further enhances the safety performance of the equipment. At the same time, after receiving the gas, the locking cylinder 15 will push the piston 16 and the locking rod 17 to move, thereby fixing the limiting pipes of different diameters to achieve interchangeability of the diameters, which further enhances the applicability and flexibility of the splitting equipment. In addition, the mechanism has a simple structure, is easy to operate, reduces the cost of use, and has broad application prospects.
