Description

Technical Field

[0001] The utility model relates to a drilling device, in particular to a drilling device for engineering geology, belonging to the technical field of geological drilling equipment. Background Art

[0002] Geological drilling refers to the use of a drilling rig to drill holes in the strata to identify and divide the subsurface strata and to take samples along the depth of the hole. Drilling is the most widely used engineering geological exploration method in engineering geological surveys. It can obtain deep geological data such as rocks, strata, structural landforms and other geological conditions.

[0003] Currently, the commonly used drilling machines are relatively large in size, such as the HGY-300 geological drilling machine and the XY100 drilling machine. When used, they need to be transported to the corresponding mining exploration area for installation and then drilling. They require a larger working site and cannot adapt to shallow geological surface drilling in the field.

[0004] The Chinese utility model patent with application number CN202020587128.3 discloses a geological prospecting drilling device, including a base, a mounting tube is provided on the top of the base, a gear support ring is placed in the middle of the top of the base, a driven gear is placed on the gear support ring, the screw is sleeved on the base, a gear is provided on the driven gear, the driven gear is meshed with a driving gear, a driving shaft is fixedly connected to one side of the driving gear, the driving shaft is fixedly installed on the top of the bearing bracket, a drill bit is fixedly installed at the bottom of the screw, and a fixing bolt is sleeved inside the mounting tube. The geological prospecting drilling device is novel in design, and the fixing bolt and the mounting tube are used to replace the integral bracket of the device, so the structure is simpler, the volume is small, and it can be easily carried in use, which is more practical for drilling in the shallow geological layer. However, for a field environment with a certain slope and more complex, it is impossible to adjust the drilling direction of the drill bit to achieve vertical drilling after installing the fixing bolt, so the center is extremely unstable during drilling.

[0009] A link mechanism is symmetrically arranged at both ends of the balance board, the link mechanism comprises a first link and a second link, the adjacent ends of the first link and the second link are rotatably connected, a screw that can lock and limit the relative rotation of the first link and the second link is provided at the rotation connection, and the other ends of the first link and the second link that are away from each other are rotatably connected to the balance board and the base respectively;

[0010] Furthermore, the screw rod is L-shaped, with a boss provided thereon, a threaded section from the boss to one end thereof, and a nut which can tighten the rotational connection end of the first connecting rod and the second connecting rod is connected to the threaded section;

[0011] Furthermore, a convex point is provided on the contact surface between the nut and the first connecting rod or the second connecting rod;

[0012] Furthermore, a level is provided on the upper surface of the balance board;

[0013] Furthermore, the balancing plate and the base are provided with corresponding openings, and the drill installed below the driving member passes through the openings in sequence;

[0014] Furthermore, a fixing pin is provided on the supporting foot of the base.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the balance plate provided in the utility model can be adjusted to a certain angle. When drilling on a geological surface with a slope in a field environment, the balance plate can be adjusted to a horizontal position, so that the drill bit can drill vertically downward, thereby improving the stability and adaptability during drilling.
