Abstract

The invention relates to a dry sand sampling drill. An internal drill bit is connected with an internal drill handle, an external drill bit is connected with an external drill handle, the internal drill bit is inserted into the external drill bit and is provided with a baffle, one end of the baffle is connected with the internal drill bit, and the other end of the baffle penetrates through the internal drill bit to extend out via a rope. The external drill bit of the external drill is inserted into sand, and the sliding collapse of walls of sand flow holes can be avoided due to the external drill; and the inner wall of the internal drill is a hollow cavity, the movable baffle is arranged in the cavity, and when the external drill is inserted into the sand, the internal drill is inserted into the external drill, the movable baffle is opened and is then closed through pulling the rope when drilling is carried out to a certain depth, and thus the sand can be removed. Therefore, the sampling is convenient and simple, and labor can be saved.

Description

technical field [0001] The invention relates to a dry sand sampling drill for engineering. Background technique [0002] The dry sand sampling device is an urgently needed equipment in engineering construction or soil quality investigation and research. At present, sampling methods are mostly used such as excavation, which is time-consuming, laborious and inconvenient. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a dry sand sampling drill, which can obtain the required sand samples and is simple and convenient to use, saving time and effort. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A dry sand sampling drill, the inner drill bit 1 is connected to the inner drill handle 2, the outer drill bit 3 is connected to the outer drill handle 4, the inner drill bit 1 is inserted into the outer drill b...
