Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to geological exploration drilling equipment. Background Art

[0002] Geological survey is the abbreviation of geological exploration work, which is to conduct investigation and research on the geological conditions such as rocks, stratigraphic structures, minerals, groundwater, and landforms in a certain area with different focuses. The portable field drilling equipment is generally a handheld drill, which conducts geological analysis on the soil drilled out.

[0003] However, this type of handheld drill generally has the following two problems during use: 1. The samples drilled out of the drill rod will be scattered all over the ground due to insufficient centripetal force, making them difficult to collect and causing serious sample contamination; 2. The handheld drill has no fixed structure, so it is difficult to maintain direction and requires manual judgment of direction, which lacks accuracy. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide geological exploration drilling equipment to meet the needs of collecting samples while drilling and being able to fix the handheld drill on the surface.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is:

[0006] geological exploration drilling equipment, including hand-held drills;

[0007] A drill pipe and a collecting bucket; the top of the drill pipe is fixed on the housing of the handheld drill, and the drill bit of the handheld drill passes through the drill pipe for drilling; a discharge port is provided at the upper end of the drill pipe near the housing of the handheld drill; the collecting bucket is sleeved and fixed in the middle of the drill pipe;

[0008] A ground nail, a ground nail tube and a flip bracket; the ground nail tube is erected on one side of the drill pipe through the flip bracket, and after flipping up and down around the middle and lower part of the drill pipe, it is fixed on the drill pipe through the flip bracket; the ground nail passes through the ground nail tube and fixes the ground nail tube to the ground.

[0009] As an improvement, the flip bracket includes a support rod 1 and a support rod 2. One end of the support rod 1 is hinged to the drill pipe, and the other end is fixedly connected to the end of the support rod 2 and fixed to the outer wall of the ground nail tube. The other end of the support rod 2 is hinged to the drill pipe. The support rod 1, the support rod 2 and the drill pipe form a triangular structure. The triangle has stability, so the structural strength can be increased.

[0010] As an improvement, the second support rod includes a sleeve, a sleeve rod and a hand screw. The bottom end of the sleeve rod is fixedly connected to the first support rod. The sleeve is movably sleeved on the sleeve rod and fixed at different positions on the sleeve rod by the hand screw. The top of the sleeve is hinged to the drill bit tube. The sleeve rod is provided with a positioning screw hole that matches the hand screw. A plurality of positioning screw holes are evenly arranged along the axial direction of the sleeve rod. The advantage of this is that it avoids the loosening of the hand screw due to vibration, and at the same time increases the supporting strength of the second support rod.

[0011] The advantages of the utility model compared with the prior art are:

[0012] 1. By setting up a collection bucket, the drilled samples can fall completely into the collection bucket, avoiding sample contamination caused by samples falling on the ground, and also avoiding sample contamination caused by samples falling into the borehole;

[0013] 2. By setting up structures such as brackets and ground spikes, the handheld drill can be firmly fixed to the ground, maintaining a constant drilling direction for greater accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
