Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling equipment, and more specifically to an automatic sampler for drill cuttings of an open-pit down-the-hole drill. Background Art

[0002] Open-pit drilling refers to the process of drilling holes into the ore body using drilling machinery to form blastholes in an open-pit mine. This process is the first step in open-pit mining, aiming to provide the necessary space for subsequent blasting operations, effectively breaking and loosening the ore, facilitating subsequent shoveling and transportation processes.

[0003] During the drilling process, down-the-hole drilling will generate a large amount of drill cuttings, which will accumulate near the mouth of the blasthole. By collecting the soil drill cuttings at a specific depth and analyzing the different grades of elements contained in the drill cuttings at a specific depth, guidance can be provided for the next production step. However, existing drilling equipment generally does not have a sampling structure installed, and cannot collect the soil drill cuttings accumulated near the drill hole in real time during drilling. If the drill cuttings are collected after drilling, the soil drill cuttings at different depths will be mixed together, resulting in the inability to collect soil drill cuttings samples at a specific depth.

[0026] Example:

[0027] See also Figures 1-4 , an open-pit down-the-hole drilling rig cuttings automatic sampler, comprising:

[0028] A control box 1 is provided. Two L-shaped connecting plates 3 are fixedly connected to the outer surface of one side of the control box 1.

The bottom of the transmission block 8 is fixedly connected to a transmission plate 5 via two fixing rods. A micro-electric telescopic rod 6 is fixedly installed on the bottom of the transmission plate 5. The output end of the micro-electric telescopic rod 6 is fixedly connected to a mounting frame 10. A semi-cylinder-shaped soil shovel 12 is rotatably connected between the inner walls of the two sides of the mounting frame 10.

A transmission worm 15 is rotatably connected between the upper and lower inner walls of the side connection box 13. The transmission worm 15 is meshed with the transmission worm gear 14.

[0030] In a specific embodiment of the present invention, the control box 1 is installed on the drilling rig through other connecting parts. When the drilling rig is working, a large amount of soil cuttings accumulate around the drill hole. By controlling the micro electric telescopic rod 6 to start, the mounting frame 10 and the semi-cylinder type soil shovel 12 are driven to descend, and then the transmission threaded rod 7 is controlled to rotate to drive the transmission block 8 to move, so that the transmission plate 5 drives the mounting frame 10 and the semi-cylinder type soil shovel 12 toward the soil cuttings pile through the micro electric telescopic rod 6, shoveling part of the soil cuttings into the interior of the semi-cylinder type soil shovel 12, and then the transmission threaded rod 7 is controlled to reverse, driving the semi-cylinder type soil shovel 12 out of the soil cuttings. The micro electric telescopic rod 6 drives the mounting frame 10 and the semi-cylinder shovel 12 to rise, and then drives the transmission worm 15 to rotate, drives the transmission worm wheel 14 to rotate, and drives the semi-cylinder shovel 12 to rotate through the rotating shaft rod, and pours the soil drill cuttings sample inside the semi-cylinder shovel 12 into the inside of the collecting box 4, thereby completing the sampling work in the drilling process. The device can automatically complete the real-time collection of soil drill cuttings at a specific depth during the drilling operation without manual intervention. The working efficiency is very high and the sampling accuracy is high, which is helpful to analyze the different grades of elements contained in the drill cuttings and can provide guidance for the next production step.

[0032] In this embodiment, the driving motor 2 is controlled to start, so as to drive the transmission threaded rod 7 to rotate.

[0033] Specifically, two limit rods 9 are fixedly connected between the inner walls on both sides of the control box 1 , and the transmission block 8 is slidably sleeved on the two limit rods 9 .

[0034] In this embodiment, the two limiting rods 9 enable the transmission block 8 to remain stable during the movement.

[0035] Specifically, the two limiting rods 9 are both made of stainless steel.

[0036] In this embodiment, the surface of the limiting rod 9 is smooth, has low friction, is strong and corrosion-resistant.

[0037] Specifically, a limited telescopic rod 11 is fixedly connected between the transmission plate 5 and the installation frame 10 .

[0040] In this embodiment, the servo motor 16 is controlled to start, thereby driving the transmission worm 15 to rotate.

[0041] Working principle: When the drilling rig is working, a large amount of soil cuttings accumulate around the drill hole. The micro electric telescopic rod 6 is controlled to start, driving the installation frame 10 and the semi-cylinder type soil shovel 12 to descend. Then, the drive motor 2 is controlled to start, driving the transmission threaded rod 7 to rotate, driving the transmission block 8 to move, so that the transmission plate 5 drives the installation frame 10 and the semi-cylinder type soil shovel 12 to move toward the soil cuttings pile through the micro electric telescopic rod 6, and shovels part of the soil cuttings into the inside of the semi-cylinder type soil shovel 12. Then, the drive motor 2 is controlled to reverse, driving the transmission threaded rod 7 to reverse, driving the semi-cylinder type soil shovel 12 out of the soil cuttings pile, and the micro electric telescopic rod 6 drives the installation frame 10 and the semi-cylinder type soil shovel 12 to rise. Then, the servo motor 16 is controlled to start, driving the transmission worm 15 to rotate, and the transmission plate 5 drives the installation frame 10 and the semi-cylinder type soil shovel 12 to move toward the soil cuttings pile. The dynamic transmission worm gear 14 rotates, driving the semi-cylindrical soil shovel 12 to rotate through the rotating shaft rod, and pouring the soil drill cuttings sample inside the semi-cylindrical soil shovel 12 into the inside of the collecting box 4, thereby completing the sampling work during the drilling process. This device can automatically complete the real-time collection of soil drill cuttings at a specific depth during the drilling operation without manual intervention. The work efficiency is very high and the sampling accuracy is high. It helps to analyze the different grades of elements contained in the drill cuttings and can provide guidance for the next production step. The control method of the utility model is to control it by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in this field, and the utility model is mainly used to protect mechanical devices, so the utility model no longer explains the control method and wiring layout in detail.
