The invention discloses a hydrogeological drill type detection device, and belongs to the technical field of hydrogeological detection. The hydrogeological drill type detection device comprises a supporting frame, a stabilizing frame, a drilling assembly arranged on the stabilizing frame and a power assembly arranged on the supporting frame. The drilling assembly comprises a drilling barrel and adrilling rod which are vertically arranged; the top of the drilling barrel is connected with the power assembly, the outer side wall of the drilling barrel is connected with the stabilizing frame through threads, and a first conical surface is arranged at the bottom end of the drilling barrel; the drilling rod penetrates through the drilling barrel, the top of the drilling rod is connected with the power assembly, the side wall of the drilling rod is connected with the inner side wall of the drilling barrel through threads, a drill bit is arranged at the bottom of the drilling rod, and a second conical surface of the drill bit is located in the extending direction of the first conical surface. Sampling is conducted through a threaded groove, soil of other depths cannot enter the threadedgroove of the drilling rod in the sampling process, soil of other depths is prevented from entering a sample, and therefore detection errors caused by mixing of other soil are avoided.

The invention relates to stratified sampling equipment for soil detection. The stratified sampling equipment comprises a driving device; a drilling barrel which is driven by the driving device to enter target soil; and a sampling mechanism which is telescopically located in the drilling barrel and used for stretching out of one end of the drilling barrel to take the target soil after the drillingbarrel enters the target soil, wherein the sampling mechanism is provided with a drilling rod and a plurality of sampling grooves located in the outer side wall of the drilling rod at different heights. According to the stratified sampling equipment for soil detection, the driving device is utilized to enable the drilling barrel to drill into the target area, and then the sampling mechanism is used for sampling so that the sampling efficiency is improved and the soil can be taken out conveniently.
