Description

Technical Field

[0001] The utility model relates to the technical field of drilling exploration, in particular to a rock and soil exploration drilling device. Background Art

[0002] Geotechnical investigation is the use of testing means and methods to investigate and study the site, and analyze and determine the structure, formation age, cause, and soil type of the foundation rock and soil layers. Geotechnical investigation often requires the use of drilling equipment to drill the surface of the rock and soil in advance.

[0003] When drilling with a drill bit, it is necessary to water the drilling area. However, it is difficult to directly pour water on the rock and soil near the drill bit. Most of the water is absorbed by the soil above the drilling point in advance, which has a poor protection effect on the drill bit. Therefore, those skilled in the art provide a geotechnical exploration drilling device to solve the problem. Utility Model Content

[0007] Preferably, the two semi-cylindrical blocks are sleeved on the side surfaces of the two output shafts, and the inner sides of the semi-cylindrical blocks do not contact the side surfaces of the output shafts, thereby preventing friction between the semi-cylindrical blocks and the output shafts.

[0008] Preferably, a plurality of matching columns are symmetrically fixedly installed on one of the semi-cylindrical blocks, and a plurality of matching holes are symmetrically opened on the other semi-cylindrical block. The plurality of matching columns are respectively inserted into the plurality of matching holes, so that the two semi-cylindrical blocks restrict each other and improve stability.

[0010] Preferably, a plurality of positioning pins are provided on the side of the support frame, so as to position the whole frame.

[0011] In summary, the utility model includes the following beneficial technical effects:

[0012] Insert the bottom of the connecting rod into the plug plate and fix it with threads and nuts, insert the top of the connecting rod into the top plate and fix it with threads and nuts. During the installation of the connecting rod, the plug plate can move laterally in the plug block, and the plug block can move vertically in the guide frame. The matching column can cooperate with the matching hole to improve the stability of the semi-cylindrical block. The pipe on the side of the semi-cylindrical block can be filled with water, and the pipe at the bottom can discharge the water. The water falls vertically onto the drill bit, which is more accurate and can moisten the rock and soil at the drilling site, thereby minimizing water loss and protecting the drill bit.
