Description

Technical Field

[0001] The utility model relates to the technical field of drilling sampling machines, and more specifically, the utility model relates to a drilling sampling machine. Background Technique

[0002] A drilling sampling machine is a device that can drill shallow holes dozens of meters deep in surface soil and rock formations and can take soil samples and rock cores. The drilling sampling machine can provide accurate and effective underground information for geological exploration, construction, environmental investigation, etc., and is widely used in the field of coal mine geology;

[0003] In the prior art, through the setting of a stable support mechanism, the support stability of the drilling sampling pipe during the drilling sampling process can be corrected. However, during the actual use process, there will still be shaking phenomena, resulting in unsatisfactory stability. Moreover, the contact surface between the support mechanism and the ground is limited, and the self-weight of the sampling machine easily causes the support bottom plate to settle, and the problem of insufficient stability cannot be well solved;

[0004] Chinese Patent with the patent application number CN202322881067.8 discloses a drilling sampling machine, including a chassis, a support frame, a rotating structure and a lifting structure; the rotating structure includes a rotating plate and a fixing plate, and the fixing plate is located at the outer end of the chassis. The roller is rotatably connected to the chassis through the rotating plate, and the roller can be directly rotated to the bottom end of the chassis. At this time, the sampling machine can be moved; conversely, under the reaction of the spring, the roller can be retracted to the outer end of the chassis. When using the sampling machine, the chassis can be in contact with the support frame, improving the stability of the sampling machine;

[0005] However, it can be seen from the accompanying drawings of its specification that the length of the rotating shaft is fixed. When the depth of the drilling sampling position is relatively deep, it is inconvenient to adjust and use. Moreover, the equipment is only supported by the bottom plate and the supporting legs around. When the ground is uneven, the equipment will be placed unstably, and the stability of the equipment placement cannot be adjusted according to the ground inclination, thereby affecting the stability of the equipment operation and the use effect.
