[0025] As Figure 3 shown, two limiting slide bars 6 are fixedly installed on the power rod 203. Two limiting chutes are opened in the drill rod 201. The limiting slide bars 6 are adapted to the limiting chutes;

[0026] By the adaptation of the limiting slide bars 6 to the limiting chutes, the limiting slide bars 6 can slide in the limiting chutes. At the same time, the limiting slide bars 6 play a limiting role, so that after the power rod 203 rotates, the drill rod 201 can be driven to rotate through the limiting slide bars 6.

[0027] As Figure 1 and Figure 2 shown, a protective shell 4 is fixedly installed on the support frame 2. A double-shaft motor 401 is fixedly installed on the support frame 2. The double-shaft motor 401 is located inside the protective shell 4. Two rotating rods 402 are rotatably installed on the protective shell 4.

[0031] As Figure 1 shown in the figure, four roller assemblies 101 are fixedly installed at the bottom of the support frame plate 1, and the four roller assemblies 101 are distributed in a rectangular array along the bottom of the support frame plate 1;

[0032] By providing the roller assemblies 101, it is convenient to move and adjust the drilling position of the device.

[0033] The working principle of the drilling device for hydrogeological exploration provided by the present utility model is as follows:

[0034] First step: Move the device to the designated drilling position through the roller assemblies 101. Then, the double-shaft motor 401 is energized and runs. Then, the double-shaft motor 401 drives the two rotating rods 402 to rotate synchronously. Then, the rotating rods 402 can drive the third cone pulley 403 and the fourth cone pulley 404 to rotate simultaneously. Then, the first cone pulley 204 engaged with the fourth cone pulley 404 will be driven to rotate. Then, the power rod 203 is driven to rotate by the first cone pulley 204. Then, the power rod 203 can drive the drill rod 201 to rotate through the limiting action of the first cone pulley 204. Then, the drill rod 201 drives the drill bit 202 to rotate and drill the soil layer;

[0035] Second step: Then, the second cone pulley 306 engaged with the third cone pulley 403 can be driven to rotate. Then, the second cone pulley 306 drives the adjusting screw 305 to rotate spirally. Then, the adjusting screw 305 spirally drives the lifting block 303 to move up and down. Secondly, the lifting block 303 drives the collar 301 to move up and down through the connecting rod 302. Therefore, the rotating drill rod 201 is driven to move up and down by the collar 301, which is convenient for controlling the drilling depth of the drill bit 202;

[0036] Third step: After rotating the second adjusting block 504, loosen the positioning screw 503, and then release the limiting state of the support arm 5, so that the support arm 5 can be rotated. Through the support arm 5, the support position of the support screw 501 can be selected. Then, tighten the positioning screw 503 again to position and fix the support arm 5 at the rotated and adjusted position. Then, turn the first adjusting block 502 to drive the support screw 501 to rotate spirally on the support arm 5. Then, after the support arm 5 is adjusted up and down, it is convenient to support and balance the support frame plate 1 on the uneven ground and keep it stable, which is convenient for geological exploration drilling.
