It should be noted that in the description of the present invention, the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are only for convenience of description and simplification of description, and do not indicate or imply that the referred device or element must have a specific orientation, be configured in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

Further, it will be appreciated that the dimensions of the various elements shown in the figures are not drawn to scale, for ease of description, and that the thickness or width of some layers may be exaggerated relative to other layers, for example.

It should be noted that like reference numerals and letters refer to like items in the following figures, and thus, once an item is defined or illustrated in one figure, it will not need to be further discussed or illustrated in detail in the description of the following figure.

As shown in fig. 1 to 6, the present invention provides a technical solution: the utility model provides a geological survey core drill, which comprises a housing 1, can adopt the stainless steel material that has excellent corrosion resistance, formability and obdurability, make housing 1 life longer, the inside appearance pipe 2 that is provided with of housing 1, the inside inner tube 3 that is provided with of appearance pipe 2, the inside swing joint of inner tube 3 has spliced pole 301, spliced pole 301 one side outer lane fixedly connected with a plurality of first long boards 4, the inner circle fixedly connected with a plurality of second long boards 406, spliced pole 301 one side fixedly connected with electric putter 202, in this embodiment, electric putter 202's standard stroke is at 400mm, its maximum force can reach 6000N, no-load operating speed is 40mm/s, electric putter 202 uses 24V/12V direct current permanent magnet motor as the power supply, convert the rotary motion of motor into linear reciprocating motion. It should be noted that the use of the electric ram 202 as an actuator not only reduces the air supply and auxiliary equipment required for use with pneumatic actuators, but also reduces the weight of the actuator. Because the pneumatic actuating mechanism needs to have certain air pressure in the whole control operation process and has larger air consumption, the electric push rod 202 is adopted as the actuating mechanism, when the control opening degree is changed, power needs to be supplied, and the power can not be supplied when the required opening degree is reached, so that the electric push rod 202 actuating mechanism has obvious energy-saving advantages compared with a pneumatic actuating mechanism in terms of energy saving, therefore, in this embodiment, it is preferable to adopt the electric push rod 202 as an actuating structure, the first long plate 4 and the second long plate 406 are symmetrically and fixedly connected with the connecting blocks 402 on one side, the rotating shaft 401 is fixedly connected between the connecting blocks 402, the first stopper 404 is arranged at the bottom of the first long plate 4, the second stopper 405 is arranged at the bottom of the second long plate 406, one side of each of the first stopper 404 and the second stopper 405 is movably connected with the rotating shaft 401, and the top of each of the first stopper 404 and the second stopper 405 is fixedly connected with the first long plate 4 and the second long plate 406 through a plurality of springs 403. It should be noted that the length of the first long plate 4 is smaller than that of the second long plate 406, and it should be noted that the motor 101 and the electric push rod 202 are electrically connected to the controller 5. It should be understood that the first stopper 404 and the second stopper 405 are retracted into the inner tube 3 by the driving of the electric push rod 202, so that the diameter of the outer circle formed by the first stopper 404 and the second stopper 405 should be smaller than the diameter of the inner circle of the inner tube 3, and the diameter of the outer circle of the first stopper 404 and the second stopper 405 after being spread apart by the pulling force of the spring 403 is adapted to the sample collecting tube 2. It is emphasized that when the spring 403 is in use, the outer layer is covered with a protective soft shell to prevent the core from entering and causing the spring 403 to lose its function.

As a specific embodiment, the bottom of the shell 1 is screwed with a drill 102, the top is fixedly connected with a motor 101, the top of the motor 101 is fixedly connected with a square plate 103, the top of the square plate 103 is fixedly provided with a controller 5, and the top of the square plate 103 is fixedly connected with a handle 104.

As a specific embodiment, the top of the housing 1 is fixedly connected with a housing cover 105, and one side of the sample receiving tube 2 is screwed with the housing cover 105. It should be noted that, the sampling tube 2 is screwed with the shell cover 105, so that the sampling tube 2 can be more conveniently detached, and the sampling tube 2 can be cleaned and replaced in the later period.

As a specific embodiment, a fixing ring 203 is fixedly connected to the inner tube 3, a top cover 201 is fixedly connected to one side of the electric push rod 202, and the fixing ring 203 and the top cover 201 are fixedly connected with the sampling tube 2.
