Description

Technical Field

[0001] The utility model relates to the technical field of geotechnical engineering, in particular to a drilling device for geotechnical engineering investigation. Background Art

[0002] Drilling is one of the main means of geotechnical engineering investigation. The purpose of geotechnical engineering investigation is mainly to identify engineering geological conditions, analyze existing geological problems, and make engineering geological evaluations of construction areas. In the process of geotechnical investigation, drilling is required to analyze rock formations. The geological borehole must be processed first, and then the probe of the detection instrument is placed into the hole to detect geological data.

[0003] During the use of the existing drilling devices for geotechnical engineering surveys, the devices need to be fixed on the ground when they are working to improve the stability during drilling. Usually, the cones that connect the devices to the ground need to be knocked into the soil layer by workers with the help of tools to form a fixed connection with the ground. However, the above operation is not only too cumbersome, but also may cause the device to tilt during the knocking process, thereby reducing the stability of the device when it is working. In addition, a large amount of dust will be generated during the drilling operation. Usually, a dust suction mechanism is set up to effectively collect and process the dust, improve the working environment, and protect the health of the operators. However, the uninterrupted operation of the dust suction mechanism during continuous operation will cause the filtering capacity of the filter to exceed the load, resulting in clogging of the filter, and then causing the device to malfunction. Usually, the dust suction mechanism cannot solve the problem of easy clogging of the filter, affecting the stability of the device operation. Utility Model Content
