Description

Technical Field

[0001] The utility model belongs to the technical field of civil engineering survey, and in particular relates to a handheld rock sample directional drilling device. Background Art

[0002] A handheld rock sample directional drill is a portable device used to drill rock samples in geological surveys and determine the direction for the samples. When using the handheld rock sample directional drill, the operator inserts the drill bit into the ground and starts the drill. The drill will rotate the drill rod and gradually advance into the rock until the required depth is reached or enough rock samples are obtained. After the drilling is completed, the sampler will be used to cut and collect rock samples and store them in appropriate containers. The directional instrument will simultaneously record the direction and inclination of the borehole. After the drilling is completed, the rock samples can be analyzed on the field or taken back to the laboratory for detailed study. The handheld rock sample directional drills currently on the market have the following problems when used:

[0003] During the use of the handheld rock sample directional drill currently used in the market, the drill bit drills into the rock, and the rock powder produced by sampling will mix with water to form a mud mixture. During the sampling and pulling process, the rock sample may be stuck in the inner cavity of the drill bit and difficult to be removed, resulting in sampling difficulties and a low degree of sampling integrity.
