Abstract

The invention discloses a geological sampling device with high output torque and low noise, which comprises a geological sampling vehicle and an engine connected with the geological sampling vehicle. The engine is used to drive the geological sampling vehicle. Part includes a compression chamber, a pump chamber, a return chamber and a hydraulic circuit. The compression chamber is arranged at the rear of the engine, and a first oil port and a second oil port are arranged on it. The first oil port and the second oil port The first control valve and the second control valve are respectively connected to the compression accumulator, and the pump chamber is respectively connected to the low-pressure oil circuit and the high-pressure oil circuit through the check valve. A pressure reducing valve is set on the oil pipeline from the high pressure accumulator to the cylinder body, and a start valve is set on the oil pipeline between the compression accumulator and the high pressure accumulator. The geological sampling device has simple structure, convenient manufacture, high scavenging efficiency, stable performance, large output torque, and a complete control system and position detection system are designed.

Description

technical field [0001] The invention relates to the geological field, in particular to a geological sampling device with high output torque and low noise. Background technique [0002] Geological sampling is an important link in the geological field, and it is also the initial link to obtain geological samples. Due to the particularity of geological sampling work, geological sampling devices, mainly geological sampling vehicles, have become an important means of transportation and sampling. [0003] How to further reduce the working energy consumption of the geological sampling device, mainly the geological sampling vehicle and improve the work efficiency, is a problem that people have been concerned about. The current geological sampling vehicles are basically driven by engines, and the existing engines generally have problems such as overly complex structures, inaccurate control, and insufficient output torque. Therefore, we can improve the performance of geological sampl...
