Embodiment

[0053] like figure 1 As shown, a high-efficiency rock and soil sampling device includes a fixed bracket assembly 1, a gasoline engine 2, a transmission assembly 3, and a drilling assembly 4 that are installed on the fixed bracket assembly 1 and connected in sequence, and between the gasoline engine 2 and the fixed bracket assembly 1. A sliding assembly 5 is also connected between them, allowing the gasoline engine 2 to move up and down along the fixed bracket assembly 1. The drilling assembly 4 is externally connected with a water cooling system 6 .

[0054] like figure 1 As shown, the fixed bracket assembly 1 includes a vertical sliding bar 11 and a base bracket 12 installed at the bottom of the vertical sliding bar 11 . A slideway 111 is provided on the vertical slide bar 11 for a slide assembly 5 to slide along it in the future. In order to maintain balance, a counterweight 112 is provided at the bottom of the vertical slide bar 11 in the direction away from the gasoline...

Abstract

The invention discloses a high-efficiency ground sampling device and a sampling method, and belongs to the field of geotechnical exploration equipment. The device and the method have an advantage thatthe sampling efficiency is improved. According to the technical scheme, the high-efficiency ground sampling device comprises a fixed support component, a gasoline engine, a transmission component anddrilling components, wherein the gasoline engine, the transmission component and the drilling components are arranged on the fixed support component and are connected in sequence; the drilling components are externally connected to a water cooling system; the gasoline engine is connected to the transmission component; the transmission component is arranged in a mounting box; a driving wheel, a driving shaft which is coaxial to the driving wheel, a driven wheel, a driven shaft which is coaxial to the driven wheel, and a transmission chain which is arranged between the driving wheel and the driven wheel are arranged in the mounting box; the driving shaft is connected to a piston of the gasoline engine through a coupling; one end, far away from the gasoline engine, of the driving shaft and one end, far away from the gasoline engine, of the driven shaft are respectively connected to a set of drilling components; and a sliding component is connected between the gasoline engine and the fixed support component, and the gasoline engine moves up and down along the fixed support component.

Description

technical field [0001] The invention relates to the field of rock and soil sampling, more specifically, it relates to a high-efficiency rock and soil sampling device and a sampling method. Background technique [0002] In the geotechnical engineering survey work in mountainous and hilly areas, due to the high altitude of the project area, it is difficult to transport and fetch water for large-scale engineering survey drilling rigs, and the applicability is poor. From this, a core sampling package assembly has been gradually developed, with an overall mass of about 20kg, which is light and efficient. Specifically include: main engine, probe rod, drilling tool, drill bit, water supply system, positioning parts, etc. [0003] The existing patent CN207703520U discloses a geotechnical sampling device in geotechnical engineering, including a gasoline engine, a split sampling rod and a support, the output shaft below the gasoline engine is engaged with the gear set, and the gear s...
