[0002] Geological survey is the abbreviation of geological exploration work. Geological exploration work is an investigation and research work with different focuses on the geological conditions such as rocks, stratigraphic structure, minerals, groundwater and landforms in a certain area. There are different geological exploration work according to different purposes.

[0003] However, during geological surveys, it is necessary to take soil samples from different soil layers within a certain area for observation and research. Currently, when taking soil samples from different soil layers, most of the time, a sampling tube is inserted into the ground, and then the soil is taken out and stored after the sampling tube is removed. Then, the soil is sampled again by inserting the tube into the soil at different depths. The back-and-forth operation is time-consuming, labor-intensive, and cumbersome, which reduces the overall work efficiency. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-6 As shown, an engineering geological survey device includes a drill bit 1, and a sampling mechanism 2 is installed at the bottom of the drill bit 1, and the sampling mechanism 2 includes a rotating groove 204. The bottom side wall of the drill bit 1 is provided with multiple groups of equidistant rotating grooves 204, and three annular equidistant rotating grooves 204 form a group. A collection box 202 is respectively provided inside the multiple rotating grooves 204, and one end of the collection box 202 is rotatably connected to the inside of the rotating groove 204 through a rotating shaft 205. The rotating shaft 205 is fixedly connected to the collecting box 202, and both ends of the rotating shaft 205 are rotatably connected to the inside of the drill bit 1. A first torsion spring 206 is provided at both ends of the rotating shaft 205, and one end of the first torsion spring 206 contacts the side wall of the collecting box 202, and the other end of the first torsion spring 206 contacts the inside of the drill bit 1. The collection box 202 is an arc structure, and a control mechanism 3 is installed on the drill bit 1.

[0024] As a technical optimization solution of the present invention, a symmetrical handle 201 is installed on the outer side of the top of the drill bit 1. The handle 201 is a cylindrical structure. The installation of the handle 201 facilitates the holding of the drill bit 1, and facilitates the insertion into the ground and rotation to achieve soil sampling.

[0025] As a technical optimization solution of the present invention, the collection box 202 is an arc-shaped structure with an open end, and multiple side walls of the collection boxes 202 are provided with sharp teeth 203, which are conducive to the sudden scraping of the collection box 202 on the ground when the drill bit 1 rotates, thereby realizing the collection and storage of the scraped soil.

[0026] As a technical optimization solution of the present invention, the control mechanism 3 includes a rotating sleeve 305, and the drill bit 1 is rotatably connected to a plurality of equidistantly distributed rotating sleeves 305. The side walls of the plurality of rotating sleeves 305 are rotatably connected to drive rods 307, and the other ends of the plurality of driving rods 307 are rotatably connected to the side walls of the collection box 202. The drill bit 1 is rotatably connected to a rotating rod 304, and the bottom of the rotating rod 304 is a hexagonal structure. The bottom of the rotating rod 304 is connected to a plurality of rotating sleeves 305 through connecting holes 306. The installation of the rotating sleeve 305 is convenient for connecting the driving rod 307. By rotating the rotating rod 304, the rotation control of the rotating sleeve 305 is achieved. The rotating sleeve 305 drives the driving rod 307 to pull the collection box 202, so that the collection box 202 is closed, which facilitates the sinking or rising of the drill bit 1. By rotating the rotating rod 304 in the opposite direction, the collection box 202 is rotated open to achieve soil scraping and collection.

[0027] As a technical optimization solution of the present invention, a turntable 301 is installed on the top of the rotating rod 304. The turntable 301 is a "M"-shaped structure, which is conducive to driving and controlling the rotating rod 304 through the turntable 301, making operation more convenient and labor-saving.

[0028] As a technical optimization solution of the present invention, a second torsion spring 308 is installed on the top of the rotating rod 304. The top of the rotating rod 304 is rotatably connected to the inner side of the top of the drill bit 1 through the second torsion spring 308. Through the installation of the second torsion spring 308, the rotating rod 304 can be reset in time after rotation, thereby realizing the control of the opening and closing state of the collection box 202.

[0029] As a technical optimization solution of the present invention, a connecting sleeve 302 is welded on the top of the drill bit 1, and the rotating rod 304 is rotatably connected to the inside of the connecting sleeve 302. Through the installation of the connecting sleeve 302, the top of the rotating rod 304 is shielded and protected, which is convenient for protection during subsequent operations.

[0030] As a technical optimization solution of the present invention, the connecting sleeve 302 is vertically threaded with a bolt 303, and one end of the bolt 303 extends to the inside of the connecting sleeve 302 and contacts the rotating rod 304. After the rotating rod 304 is rotated to a certain position, the bolt 303 is rotated to limit the contact of the rotating rod 304, so that the rotating rod 304 drives the collection box 202 to maintain a certain working state.

[0031] When the present invention is in use, first hold the handle 201, and rotate the turntable 301 to make the rotating rod 304 drive the multiple rotating sleeves 305 to rotate, and the multiple rotating sleeves 305 drive the driving rod 307 to pull the collection box 202, so that the collection box 202 is free from the elastic force of the first torsion spring 206 and rotates, so that the multiple collection boxes 202 are stored in the rotating groove 204. Then, by rotating the bolt 303, the rotating rod 304 is limited, which facilitates the insertion of the drill bit 1 into the ground. After the drill bit 1 is inserted into the ground, the bolt 303 is rotated to release the limit of the rotating rod 304, and the rotating rod 304 is driven to reset under the elastic force of the second torsion spring 308, and the rotating rod 304 is rotated. When the rod 304 is reset and rotated, the rotating sleeve 305 is driven to reset and rotate, so that multiple driving rods 307 are not pulled by external force, and multiple collecting boxes 202 are not pulled by external force. Under the elastic force of the first torsion spring 206, the rotating shaft 205 and the collecting box 202 are driven to rotate, so that the outer side of the collecting box 202 is actually kept in contact with the soil. Through the rotation of the drill bit 1, the multiple collecting boxes 202 scrape the soil of different depths, and the soil is scraped into the collecting box 202 for storage. Finally, the rotating rod 304 is rotated again, so that the multiple driving rods 307 pull the collecting box 202 to rotate and store it, which is convenient for pulling out the drill bit 1 and facilitating the subsequent removal and detection of the stored soil.
