DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0019] Please refer to Figures 1-5The application provides a technical scheme: a multifunctional drill bit switching device for geological investigation, The base 1 is used as the mounting carrier of the U-shaped support 2 and the anti-shaking assembly 8. The U-shaped support 2 is mounted on the base 1 and used as the mounting carrier of the lifting assembly 3, the anti-touching assembly 9, the energy supply assembly 10 and the protection assembly 11. The second motor 5 is connected with the lifting assembly 3 through the damping assembly 4 and used as the driving source of the drill bit 6. The drill bit 6 is connected with the second motor 5 through the quick locking assembly 7 and used for drilling operation on soil. The quick locking assembly 7 comprises: The clamping box 701 is mounted on the output end of the second motor 5. The positioning grooves 702 are all arranged on the bottom of the clamping box 701. The positioning blocks 703 are all mounted on the top end of the drill bit 6, and the positioning grooves 702 and the positioning blocks 703 are matched with each other. The cavities 704 are all arranged in the interiors of the two ends of the clamping box 701. The S-shaped plates 705 are in sliding fit with the cavities 704. The through grooves 707 are all arranged on the positioning blocks 703. The clamping grooves 708 are all arranged on the inner sides of the positioning blocks 703, and the clamping grooves 708 are located on one side of the through grooves 707. The clamping blocks 709 are all mounted on one end of the S-shaped plates 705, and the clamping blocks 709 are matched with the through grooves 707 and the clamping grooves 708. The first pre-tightening springs 706 are all mounted on one side of the inner sides of the S-shaped plates 705. The first fixed plates 712 are mounted on the outer sides of the clamping boxes 701. The positioning blocks 703 are rotatably arranged in the interiors of the first fixed plates 712. The small rotary plates 715 are mounted on the top end of the rotating shafts 713. The meshing gears 714 are mounted on the bottom end of the rotating shafts 713. The connecting rods 710 are all mounted on the ends of the S-shaped plates 705 away from the clamping blocks 709. The racks 711 are all mounted on one end of the connecting rods 710, and the two racks 711 are located on the two sides of the meshing gear 714, and the two racks 711 and the meshing gear 714 are in meshing connection.

[0020] In practical application, when it is necessary to change to a different model of drill bit 6, the small turntable 715 is manually rotated, which drives the rotating shaft 713 on the first fixed plate 712 to rotate, thereby driving the meshing gear 714 to rotate, which in turn drives the two racks 711 to move in opposite directions. This causes the two S-shaped plates 705 to slide in opposite directions within their respective cavities 704, thereby causing the locking block 709 to retract sequentially from the slot 708 and the through slot 707 into the cavity 704. This causes the first preload spring 706 to compress and deform, and then the drill bit 6 is pushed... The two positioning blocks 703 on the end are pulled out from the inside of the positioning groove 702. Then, the two positioning blocks 703 on the new drill bit 6 are simultaneously inserted into the positioning groove 702. Then, the small turntable 715 is released, and with the help of the elastic force of the two first pre-tightening springs 706, the locking blocks 709 on the two S-shaped plates 705 are driven to be inserted into the through groove 707 and the locking groove 708 in sequence. At the same time, the racks 711 on one end of the two racks 711 are driven to move towards each other, driving the meshing gear 714 on the rotating shaft 713 to reset and rotate, further driving the small turntable 715 to reset, thus realizing the quick disassembly and assembly operation of different models of drill bits 6.

[0021] This embodiment, by setting up a quick-locking component 7, enables rapid assembly and disassembly of different types of drill bits 6. This facilitates the adaptation and installation of various types of drill bits 6 on the equipment, further enabling shallow exploration and sampling surveys of geology in different regions, improving overall drilling efficiency, and preventing problems such as jamming or rusting that can easily occur when assembling and disassembling drill bits 6 using bolts and nuts. This improves the efficiency of shallow exploration, further enhances the efficiency of geological surveys, increases the applicability of the equipment, and is beneficial for practical application and operation.
