The axis of the guide rod 22 is parallel to the axis of the core barrel 14 so that the drill bit 15 can move along the axis of the guide rod 22, which guides the moving direction of the motor 11. A positioning ring 23 is slidably provided on the guide rod 22, and a locking member for fixing the positioning ring 23 is provided on the positioning ring 23.

Referring to fig. 1 and 2, a baffle 221 is integrally formed at one end of the guide rod 22, and the guide tube 21 is located between the baffle 221 and the positioning ring 23. When the guide tube 21 abuts the stop plate 221, the end of the drill bit 15 is flush with the end of the guide tube 21 facing away from the stop plate 221. A flange 211 is integrally formed at an end of the guide tube 21 facing away from the baffle 221. In the initial state, the guide tube 21 abuts against the stop plate 221 and the drill bit 15 is just able to contact the ground. By moving the positioning ring 23, the depth to be drilled into the ground is marked on the guide rod 22. The distance between the retaining ring 23 and the flange 211 is the distance the drill bit 15 can penetrate into the ground, and the feed of the drill bit 15 is stopped when the guide tube 21 is moved against the retaining ring 23.

Referring to fig. 1 and 2, in order to facilitate the operator to intuitively obtain the feeding depth, scales are axially disposed on the guide rod 22, so that the operator can more conveniently calibrate the position of the positioning ring 23.

The torsion spring 62 can urge the holding portion 63 to rotate in a direction approaching the rack 32. The retaining protrusion 64 is mated with the rack gear 32 such that the retaining protrusion 64 can engage with the rack gear 32. The torsion spring 62 is always in a stretched state, and can continuously apply an elastic force to the grip portion 63, so that the stopper projection 64 is held in an engaged state with the rack 32, thereby fixing the position of the collar 27.

Referring to fig. 1, in order to control the movement of the engine 11, a handle 16 is fixedly disposed on the engine 11, which is beneficial for a worker to hold and control the engine 11.

The embodiment of the application also discloses a surveying method, which utilizes the surveying equipment for geological surveying and comprises the following operation steps:

the surveying equipment for geological surveying is moved to a surveying place, and the state of the equipment is checked. The cutting foot 24 is inserted into the ground so that the guide bar 22 can be kept perpendicular to the ground. The clamping portion 63 is pulled outwardly so that the stop lug 64 is disengaged from the rack 32 and the two support plates 25 are brought against the ground by moving the collar 27 towards the blade foot 24. The clip 63 is released so that the stop lug 64 engages the rack 32 and thereby secures the collar 27 and ensures that the guide bar 22 stands on the ground. The guide tube 21 abuts the stop plate 221 and the drill bit 15 is just in contact with the ground.

Pulling the pull ring 45 outward separates the lock cylinder 41 from the rack 32, moving the positioning ring 23, marking the guide bar 22 where the guide tube 21 can move. The distance between the flange 211 on the guide tube 21 and the positioning ring 23 is the depth of the drill bit 15 capable of drilling into the ground.

The motor 11 is started and the core barrel 14 and the drill bit 15 are rotated together by the motor 11. The operator holds the handle 16 and moves the motor 11 along the guide rod 22 so that the drill 15 is driven into the ground, and the core barrel 14 is continuously sprayed with the cooling water while the drill 15 is driven into the ground.

The engine 11 is moved along the guide rod 22 until the flange 211 on the guide tube 21 abuts against the positioning ring 23, and the engine 11 is then switched off.

The motor 11 is raised up the guide rod 22 until the core barrel 14 and drill bit 15 are completely extracted from the ground. The core barrel 14 is removed and the core sample in the core barrel 14 is expelled by knocking the core barrel 14, leaving the core sample. The collar 27 is moved in a direction to approach the stopper so that the support plate 25 is rotated in a direction to approach the guide bar 22 and is attached to the guide bar 22.
