Detailed Description

An embodiment of a drilling apparatus for geotechnical engineering investigation according to the present invention will be further described with reference to fig. 1 to 4.

The utility model provides a drilling equipment is used in geotechnical engineering reconnaissance, including fixed disk 1, be fixed with fixed block 7 on the outer wall of fixed disk 1, the quantity of fixed block 7 is provided with two, two fixed block 7 symmetries set up the both sides at fixed disk 1, it has dwang 13 to articulate on the fixed block 7, the one end that fixed disk 1 was kept away from to dwang 13 articulates there is landing leg 3, the one end that dwang 13 was kept away from to landing leg 3 is fixed with awl foot 5, be equipped with first stop device between dwang 13 and the fixed disk 1, be equipped with the second stop device between dwang 13 and the landing leg 3, wear to be equipped with screw rod 6 on the fixed disk 1, screw rod 6 and 1 threaded connection of fixed disk, the upper end.

As shown in fig. 2 and 4, the first limiting device includes a fixing ring 10 fixed on the rotating rod 13 and a sliding ring 8 sleeved on the rotating rod 13, a limiting spring 9 is fixed between the sliding ring 8 and the fixing ring 10, and a limiting groove 18 is formed in a side surface of the sliding ring 8 facing the fixing block 7, as shown in fig. 4, when the fixing block 7 is inserted into the limiting groove 18, the rotating rod 13 is in a horizontal state, and at this time, the limiting spring 9 is in an original length state, so that the fixing block 7 is separated from the limiting groove 18, and the resilience force of the limiting spring 9 is required; as shown in fig. 2, a limiting protrusion 16 is fixed on the lower side surface of the fixing block 7, a limiting hole 17 is formed in the sliding ring 8, and when the limiting protrusion 16 is inserted into the limiting hole 17, the rotating rod 13 is in a vertical state.
