[0016] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0017] like Figure 1-3A Quaternary soil layer drilling device for geological exploration shown in the figure includes a body 1 and a shock-absorbing assembly installed on the body 1. A rotating part 2 is movably installed on one side of the body 1, and a drilling rod 3 is rotatably installed on the bottom of the rotating part 2. The shock-absorbing assembly includes a rubber ring 7, a spring 11 and a support seat 4. A groove is opened on the outer wall of the bottom of the drilling rod 3, the spring 11 is installed inside the groove, the rubber ring 7 is installed at the edge of the groove, the support seat 4 is fixedly installed at the bottom of the body 1, and a sliding plate 5 is slidably installed above the support seat 4.

[0018] A drilling port is provided on the table of the support seat 4, a U-shaped groove is provided on the outer wall of the sliding plate 5, the width of the U-shaped groove of the sliding plate 5 is adapted to the rod diameter of the drilling rod 3, a clamping plate is installed on the edge of the table of the support seat 4, and the side of the sliding plate 5 is embedded in the clamping plate. A handle 6 is fixedly installed at one end of the sliding plate 5, and a limit plate 8 is fixedly installed on the table of the support seat 4, and the limit plate 8 is installed on the side of the sliding plate 5 away from the handle 6.

[0019] The bottom end of the drilling rod 3 is provided with a mounting hole 9, the inner wall of the mounting hole 9 is provided with an internal thread, and the bottom end of the drilling rod 3 is provided with a plurality of threaded holes, which are evenly distributed outside the edge of the mounting hole 9. A matching plate 10 is installed in the groove of the outer wall of the bottom of the drilling rod 3, the threaded hole at the bottom end of the drilling rod 3 is connected with the groove, the spring 11 is fixedly installed above the matching plate 10, and the matching plate 10 is installed inside the rubber ring 7.

[0020] Embodiment: A hydraulic lifting mechanism is installed inside the machine body 1. The hydraulic lifting mechanism is adapted to be installed with the rotating member 2. The rotating member 2 drives the drilling rod 3 to rotate. The mounting hole 9 and the threaded hole at the bottom of the drilling rod 3 can be equipped with a drill bit. The drilling rod 3 explores the soil layer through the drill bit. Since the underground situation is unknown, if the drill bit encounters a hard rock layer during drilling, the drill bit will generate a large vibration when it contacts the rock layer, and the connection between the drilling rod 3 and the drill bit is easily damaged. Therefore, when installing the drill bit, the drill bit is initially fixed to the drill bit through the mounting hole 9, and then the drill bit is fixed to the threaded hole at the bottom of the drilling rod 3 with a bolt. After the bolt passes through the threaded hole, it contacts the matching plate 10, lifts the matching plate 10, and compresses and deforms the spring 11. When the drill bit is working, the spring 11 and the rubber ring 7 can act as a buffer at the connection of the drilling rod 3 to prevent the connection from being damaged due to vibration.

[0021] Before the drilling rod 3 is started, the operator will pull the sliding plate 5 through the handle 6, and the sliding plate 5 will gradually separate from the support seat 4, and the drilling port on the support seat 4 will be exposed. After the machine body 1 lowers the drill bit below the support seat 4, the operator will reset the sliding plate 5. When the sliding plate 5 is pushed to the limit plate 8, the reset is completed, and the U-shaped groove of the sliding plate 5 clamps the outer wall of the drilling rod 3. Clamping the drilling rod 3 can play a controlling role, reduce the vibration of the drilling rod 3, and protect the connection between the drill bit and the drilling rod 3.

[0022] It should be noted that the parts not covered in the present invention are the same as the prior art or can be implemented by the prior art; the various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structures in the drawings.

[0023] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
