Description

Technical Field

[0001] The invention relates to the technical field of sampling, in particular to a mining blasting sampling device. Background Art

[0002] In the process of mine exploration and development, blasting sampling is a common technical means to obtain rock or soil samples from mines for subsequent geological analysis and resource assessment. However, the existing mine blasting sampling equipment has exposed some problems in practical applications, which limits its sampling efficiency and accuracy, and also increases the maintenance cost and difficulty of the equipment.

[0003] Specifically, existing blasting sampling equipment has certain defects in the driving mechanism. Traditional equipment usually relies on a spiral structure for sampling, which is difficult to sample quickly and effectively when facing harder ores. In addition, there is also a method of blasting sampling using hydraulic impact, but this method requires hydraulic equipment and has a high overall cost.

[0004] Therefore, it is necessary to provide a mine blasting sampling device to solve the above problems. Summary of the invention

[0005] In order to solve the above problems, the present invention provides the following technical solutions: A mining blasting sampling device comprises a drill rod, a blasting sampling assembly is installed at the lower end of the drill rod, and the blasting sampling assembly comprises:

[0006] The deflagration chamber has a closed upper end and an opening at the lower end;

[0007] A receiving chamber, which is installed at the opening of the deflagration chamber and is used to receive a mounting seat;

[0008] A plurality of blasting claws distributed at intervals in the circumferential direction, one end of which is hinged to the mounting seat;

[0009] A driving rod, which slides through the mounting seat, and is hinged with a plurality of connecting rods corresponding to the blasting claws, and the other end of the connecting rod is correspondingly hinged to the blasting claws;

[0010] A piston, which is fixed to an end of the driving rod away from the blasting claw, and the piston is sealingly slidably disposed in the deflagration chamber;

[0011] Wherein, the side wall of the deflagration bin is also provided with an igniter, and the top wall of the deflagration bin is also provided with a feed pipe, and the feed pipe is used to supply the deflagration fluid;

[0012] Wherein, a second spring connected to the driving rod is installed in the mounting seat, and the second spring is a compression spring.

[0013] Further, as a preference, a sliding seat is fixed to the outside of the mounting seat;

[0015] Further, preferably, a first spring is installed between the guide cylinder and the slide seat, and the first spring is a compression spring.

[0016] Further, preferably, the bottom of the mounting seat is hinged to the blasting claw by a slide plate, the slide plate is slidably connected to the mounting seat, and an elastic member is installed between the slide plate and the mounting seat.

[0017] Further, as a preference, the drill rod is provided with drilling power by a power assembly, the power assembly is arranged on a moving assembly, and an angle adjustment assembly is also arranged between the power assembly and the moving assembly.

[0018] Further, as a preference, a plurality of mounting grooves distributed in a circumferential array are provided on the inner wall of the deflagration chamber, a clamping column is slidably provided in the mounting groove, and a return spring is provided between the clamping column and the mounting groove;

[0019] A clamping groove corresponding to the clamping column is formed on the outer peripheral side of the piston;

[0020] An electromagnetic block corresponding to the clamping column is also embedded in the inner wall of the deflagration chamber;

[0021] The energization timing of the electromagnetic block is earlier than the ignition timing of the igniter.

[0022] Furthermore, as a preference, a retracting wheel is also installed on the outside of the deflagration chamber for retracting and releasing a pull rope, and the free end of the pull rope sealably slides into the deflagration chamber and is connected to the piston.

[0025] Compared with the prior art, the present invention provides a mining blasting sampling device, which has the following beneficial effects:

[0026] In the present invention, the deflagration chamber contains the deflagration fluid and generates high-pressure gas after ignition, so that the energy can be efficiently converted into mechanical energy, driving the blasting claws to quickly deploy. The conical structure and the crushing protrusions on the outer surface of the blasting claws enhance the crushing ability and improve the sampling efficiency. The cost is low and the sampling effect for hard ores is good.

[0037] Please refer to Figure 1-Figure 5 In an embodiment of the present invention, a mining blasting sampling device is provided, including a drill rod 3, a blasting sampling assembly 5 is installed at the lower end of the drill rod 3, and the blasting sampling assembly 5 includes:

[0038] The deflagration chamber 51 is closed at its upper end and has an opening at its lower end;

[0039] A receiving chamber 52, which is installed at the opening of the deflagration chamber 51 and is used to receive a mounting seat 56;

[0040] A plurality of blasting claws 57 are circumferentially spaced apart, one end of which is hinged to the mounting seat 56;

[0041] A driving rod 59, which slides through the mounting seat 56, and a plurality of connecting rods 58 corresponding to the blasting claws 57 are hinged on the driving rod 59, and the other ends of the connecting rods 58 are correspondingly hinged to the blasting claws 57;

[0042] A piston 511, which is fixed to one end of the driving rod 59 away from the blasting claw 57, and the piston 511 is sealingly slidably disposed in the deflagration chamber 51;

[0043] The side wall of the deflagration chamber 51 is further provided with an igniter 512, and the top wall of the deflagration chamber 51 is further provided with a feed pipe 513, and the feed pipe 513 is used to supply the deflagration fluid;

[0044] The mounting seat 56 is provided with a second spring 510 connected to the driving rod 59 , and the second spring 510 is a compression spring.

[0045] The deflagration chamber 51 is a container with an opening, and its main function is to contain deflagration fluid (such as explosives or similar substances) and generate high-pressure gas after ignition to drive the blasting claws 57 to expand.

[0046] The blasting claw 57 is a plurality of claws (usually 3 or more) distributed at intervals in the circumferential direction, and one end of the blasting claw 57 is hinged to the mounting seat 56. When the deflagration fluid in the deflagration chamber 51 is ignited, the gas pressure generated pushes the blasting claw 57 to move through the driving rod 59, and pushes the blasting claw 57 to expand in cooperation with the connecting rod 58, thereby crushing the mine sample.

[0047] The piston 511 is fixed to the end of the driving rod 59 away from the blasting claw 57 and is sealed and slidably arranged in the deflagration chamber 51. The function of the piston 511 is to transfer the high-pressure gas in the deflagration chamber 51 to the driving rod 59, thereby driving it to move, and a deflagration space can be formed between the piston 511 and the deflagration chamber 51.

[0048] When it is necessary to collect a mine sample, firstly, the deflagration fluid is supplied to the deflagration chamber 51 through the feed pipe 513, and then the deflagration fluid is ignited by the igniter 512. The high-pressure gas generated by the deflagration pushes the piston 511 and the driving rod 59 to move, and the driving rod 59 pushes the blasting claw 57 to move, and pushes the blasting claw 57 to expand in cooperation with the connecting rod 58, thereby crushing the mine sample. After the sampling is completed, the second spring 510 helps the blasting claw 57 to reset.

[0049] In this embodiment, a slide seat 54 is fixed to the outside of the mounting seat 56;

[0050] A guide cylinder 53 for limited sliding connection with the slide seat 54 is fixed on the inner side of the accommodating chamber 52 .

[0051] In this embodiment, the slide 54 is an additional component fixed to the outside of the mounting seat 56. Its main function is to provide a stable sliding interface so that the mounting seat 56 (and the blasting claw 57 and other components connected thereto) can move smoothly in the accommodating chamber 52, which helps to ensure that the movement of the entire blasting sampling assembly 5 is controllable and stable during the blasting sampling process.

[0052] Matching with it, the guide cylinder 53 is fixed inside the accommodating chamber 52, serving as a sliding track for the slide 54, ensuring that the slide 54 (and the components such as the mounting seat 56 connected thereto) can slide along a predetermined path. The design of the guide cylinder 53 helps to limit the movement range of the mounting seat 56, preventing it from accidentally deviating or rotating during the blasting sampling process.

[0053] Then, when the deflagration fluid in the deflagration chamber 51 is ignited, the generated high-pressure gas pushes the piston 511 and the driving rod 59 to move. Since the driving rod 59 is connected to the mounting seat 56 through the second spring 510, and the mounting seat 56 is connected to the guide cylinder 53 through the slide 54 in a limited sliding manner, the slide 54 (and the mounting seat 56 and other components connected thereto) can move smoothly along a predetermined path in the accommodating chamber 52.

[0054] In this embodiment, a first spring 55 is installed between the guide cylinder 53 and the slide seat 54 , and the first spring 55 is a compression spring.

[0055] Among them, the main function of the first spring 55 is to store force, that is, during the blasting sampling process, when the deflagration fluid in the deflagration chamber 51 is ignited and generates high-pressure gas to push the piston 511 and the drive rod 59 to move, the first spring 55 will release the stored energy in advance, thereby increasing the power of the drive rod 59, the mounting seat 56 and the blasting claw 57 connected thereto and other components, thereby improving the sampling efficiency of the equipment.

[0056] In this embodiment, the bottom of the mounting seat 56 is hinged to the blasting claw 57 by a slide plate 516 , the slide plate 516 is slidably connected to the mounting seat 56 , and an elastic member 520 is installed between the slide plate 516 and the mounting seat 56 .

[0057] The slide plate 516 is designed to be hinged with the bursting claw 57 at the bottom of the mounting seat 56. The slide plate 516 can not only provide a more flexible and stable connection, but also play a guiding and supporting role when the bursting claw 57 is deployed and reset. In addition, an elastic member 520 is installed between the slide plate 516 and the mounting seat 56. The main function of this elastic member (which can be one or more springs, elastic sheets, etc.) is to provide a buffer force to protect the device from damage.

[0058] In this embodiment, the drilling power of the drill rod 3 is provided by a power assembly 2 , and the power assembly 2 is arranged on the moving assembly 1 . An angle adjustment assembly 4 is also arranged between the power assembly 2 and the moving assembly 1 .

[0059] In this embodiment, a plurality of mounting grooves 517 distributed in a circumferential array are provided on the inner wall of the deflagration chamber 51, a clamping column 518 is slidably provided in the mounting groove 517, and a return spring is provided between the clamping column 518 and the mounting groove 517;

[0060] The outer peripheral side of the piston 511 is provided with a clamping groove 519 corresponding to the clamping column 518;

[0061] An electromagnetic block corresponding to the clamping column 518 is also embedded in the inner wall of the deflagration chamber 51;

[0062] The timing of energizing the electromagnetic block is earlier than the timing of igniting the igniter 512 .

[0063] Among them, a plurality of mounting grooves 517 are provided on the inner wall of the deflagration chamber 51, and are distributed in a circular array. Their main function is to accommodate the clamping column 518 and provide a sliding track for the clamping column 518. When the clamping column 518 is attracted by the electromagnetic block and located in the mounting groove 517, the piston 511 is not mutually engaged with the clamping column 518, and when the electromagnetic block is powered off, the clamping column 518 can be clamped into the clamping groove 519 on the outer peripheral side of the piston 511, thereby fixing the position of the piston 511. In addition, the timing of the electromagnetic block being powered on is earlier than the timing of the ignition of the igniter 512, which means that the piston 511 has been released before the deflagration fluid is ignited. At this time, due to the elastic force of the first spring 55, the piston 511 will start to move, but since the deflagration fluid has not yet been ignited, the piston 511 is a primary movement, and then the igniter 512 is ignited, the deflagration fluid is ignited and high-pressure gas is generated. The high-pressure gas pushes the piston 511 to move quickly, thereby driving the driving rod 59, the blasting claw 57 and other components to perform blasting sampling. The whole set of actions is relatively smooth and efficient.

[0064] In this embodiment, a retracting wheel 514 is further installed on the outside of the deflagration chamber 51 for retracting and releasing a pull rope 515 . The free end of the pull rope 515 sealably slides into the deflagration chamber 51 and is connected to the piston 511 .

[0065] The retractable wheel 514 is a mechanical device installed outside the deflagration chamber 51, used to retract the pull rope 515, and one end of the pull rope 515 is connected to the retractable wheel 514, and the other end of the pull rope 515 is sealed and slidably penetrates into the deflagration chamber 51 and is connected to the piston 511. The function of the pull rope 515 is to provide an external pulling force to help the piston 511 reset after the blasting sampling is completed. The free end of the pull rope 515 penetrates into the deflagration chamber 51 through a sealing member (such as a rubber plug or a sliding sealing ring) to ensure that the deflagration fluid inside the deflagration chamber 51 will not leak.

[0066] In this embodiment, the blasting claw 57 is a conical structure, and its outer surface has crushing protrusions.

[0067] In addition, a clamping ring is fixed on one side of the blasting claw 57 close to the driving rod 59 , and a bib (not shown in the figure) is installed between two adjacent clamping rings.

[0068] The blasting claw 57 is a conical structure, which enables the blasting claw 57 to cut into the rock or soil in the mine more easily when it is unfolded, thereby improving the sampling efficiency. The outer surface of the conical structure is also provided with crushing protrusions, which can be sharp, serrated or in other shapes, for providing additional crushing force when the blasting claw 57 cuts into the rock or soil.

[0069] A clamping ring is fixed on one side of the blasting claw 57 close to the driving rod 59, and a bib is installed between two adjacent clamping rings. The bib is a flexible or semi-rigid covering. When multiple blasting claws 57 are close to each other (reset), the bib can collect samples broken by the blasting claws 57, ensuring that part of the sample will not be lost or scattered, thereby improving the accuracy and integrity of the sampling.

[0070] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
