Description

Technical Field

[0001] The present invention belongs to the field of geological exploration, and particularly relates to a portable gantry dust-proof sample cutting device and a using method thereof Background Technique

[0002] Drilling cores are usually cylindrical and have relatively large dimensions in terms of length and diameter, and cannot be directly used as experimental samples. Currently, the tool for dividing samples at the drilling site is usually a geological hammer. The size of the collected samples is much larger than the requirements of the laboratory, which is likely to cause waste of cores. Moreover, the samples collected by the laboratory also need to be processed twice, increasing the time cost and labor cost

[0003] Currently, most of the cutting equipment commonly used for cutting cores on-site is belt-driven. The rotational power of the motor is transmitted to the cutting tool through a belt to cut the core. Such cutting equipment often has large vibrations, high noise, a lot of dust, low precision, or has the disadvantages of a large appearance and a relatively complex structure, making it not suitable for use in relatively simple field environments. In view of these existing deficiencies, this invention is designed to improve the cutting precision, reduce noise, reduce vibration, and reduce dust during the cutting process of core samples Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a portable gantry dust-proof sample cutting device and a using method thereof. By setting a gantry support structure and a cutting module connected by threads, the high precision and stability during the cutting process are ensured. The threaded connection between the column and the cutting module allows for fine adjustment of the cutting height, while the gantry support structure provides a stable support, effectively reducing the shaking and deviation during the cutting process. By controlling through the operation panel, the technical problems of the traditional cutting device, such as complex operation, manual adjustment of the cutting position, and manual adjustment of the clamping assembly, are solved

[0005] The technical solution provided by the present invention is as follows

[0006] The present invention provides a portable gantry dust-proof sample cutting device, including a main body support module.

[0010] Further, the cutting grooves are two V-shaped grooves symmetrically distributed along the short side direction of the base. A dust-proof module is arranged on the cutting grooves. The dust-proof module includes a dust-proof cover covering the cutting grooves. A dust-proof cover is detachably connected above the dust-proof cover. The length of the dust-proof cover is greater than the diameter of the cutting tool. An opening corresponding to the cutting groove through which the cutting tool extends into the dust-proof cover is opened at the top of the dust-proof cover.

[0016] Beneficial Effects

[0017] (1) Most of the existing commonly used samplers are inclined downward-pressing type for cutting samples, which have large vibrations, high noise, low precision and are difficult to operate. The present invention ensures high precision and stability during the cutting process by setting up a gantry support structure and a threaded cutting module. The threaded connection between the column and the cutting module allows fine-tuning of the cutting height, while the gantry support structure provides a stable support, effectively reducing shaking and deviation during the cutting process. The control of the operating panel solves the technical problems of the traditional cutting device, which is complicated to operate and requires manual adjustment of the cutting position and manual adjustment of the clamping assembly.

[0018] (2) Most of the original samplers are of one-piece structure and cannot be disassembled. They are large in size, heavy, difficult to carry, and not suitable for field use. The portable gantry sampling device adopts a split design, which can divide the sampling equipment into multiple modules for easy assembly and disassembly. It is easy to disassemble and carry, which is conducive to the cutting of core samples in the field and convenient for the placement and movement of the device.

[0019] (3) The clamping module of the present invention can firmly fasten the sample to be cut, and the gantry support structure improves the stability of the cutting process. The reasonable combination of the two can effectively reduce the influence of vibration during cutting and significantly improve the accuracy of cutting experimental samples.

[0020] (4) The present invention designs a dust-proof module and a corresponding cutting fluid spraying component, which can confine most of the dust generated during cutting in the dust-proof cover, effectively reducing the dispersion of dust, thereby protecting the health of cutting operators.

[0021] (5) The present invention designs an automatic clamping device. By automatically lifting the upper V-shaped clamping groove, it can more conveniently and stably fasten and loosen the core samples to be divided, effectively reducing the labor intensity and improving the work efficiency.

[0022] (6) The present invention designs an auxiliary feeding and discharging module. The auxiliary feeding and discharging module can conveniently control various feeding and discharging actions through the operation panel, achieving the goal of automatic feeding and discharging, effectively reducing the labor intensity and improving the work efficiency.

[0023] (7) The present invention designs a control module for the main body support module, cutting module, clamping module, and auxiliary feeding and discharging module, which can conveniently control the clamping, loosening, and feeding and discharging actions. The control of the main body support module, cutting module, clamping module, and auxiliary feeding and discharging module is centralized on the operation panel. Through the operation panel, the actions of each component can be conveniently controlled, improving the work efficiency. Brief Description of the Drawings
