TECHNICAL FIELD
[0001] The utility model relates to geological exploration earth -excavating device technical field, concretely is a geological exploration is with the earth -excavating device that can be accomodated. BACKGROUND
[0002] In geological exploration work, obtaining accurate geological samples is the basis for analyzing key information such as underground geological structure and resource distribution. The traditional geological exploration earth -excavating device has many problems in the sampling process, especially in the rising and homing stage after sampling is completed. Loose buckling leads to frequent falling of the measured object, which seriously affects the accuracy and reliability of the exploration results.
[0003] The existing geological exploration earth -excavating device, the sampler needs to rise back to the ground after completing the underground sampling. However, in the rising process, the device will inevitably be affected by various vibrations. These vibrations may come from the mechanical movement of the device itself, or from external environmental factors such as uneven ground, bumps during transportation, etc. Due to the lack of effective auxiliary fixing mechanism in the existing device, the sampler is prone to loosen under the action of vibration, resulting in loose buckling. Some existing samplers controlled by simple mechanical structures only rely on their own gravity or simple spring return to achieve closure. In the rising process, slight vibration may change the spring force or cause relative displacement of the sampler parts, so that they cannot be tightly buckled. When the sampler rises to the ground, the measured object inside may spill out due to loose buckling. This not only causes the loss of samples, making subsequent geological analysis lack sufficient data support, but also may cause pollution to the surrounding environment, especially when exploring some areas that may contain harmful substances, the consequences are more serious.

[0021] Please refer to Figure 1 、 Figure 2 、 Figure 3 The utility model provides a technical scheme: a geological exploration device with a storable earth digging device, which comprises
[0022] The main frame 1 includes a top plate 11, an intermediate mounting plate 12 and a bottom fixing plate 13. The bottom surface of the top plate 11 is connected to the fixed end of the lifting driving device 2 and the mounting end of the measuring device 3; the intermediate mounting plate 12 is detachably connected to the lifting end of the lifting driving device 2. The measuring end of the measuring device 3 passes through the intermediate mounting plate 12 and is connected to the top surface of the bottom fixing plate 13. The top surface of the top plate 11 is provided with a groove for mounting an auxiliary support, so as to expand the function of the device or enhance the stability when needed, and also facilitate the disassembly of the outer member for storage.
[0023] The lifting driving device 2 includes a lifting end and a fixed end. The fixed end of the lifting driving device 2 is connected to the inner top surface of the main frame 1, and the lifting end of the lifting driving device 2 is connected to the sampling device 4 for driving the sampling device 4 to move up and down to realize sampling operation.
[0024] The measuring device 3 includes a measuring end and a mounting end. The mounting end of the measuring device 3 is fixedly connected to the inner top surface of the main frame 1, and the measuring end of the measuring device 3 is connected to the lifting end of the lifting driving device 2. The measuring device 3 is used to measure the lifting height or position of the sampling device 4, etc., to provide accurate sampling depth data for the operator. The measuring device 3 adopts a structure similar to a tape measure, which can adapt to a deeper depth and reduce the overall volume for easy storage and replacement.
[0025] The sampling device 4 includes a control motor 41, a support connecting rod frame 42, a connecting rod 43, a lead screw 44, a lifting linkage frame 45 and a sampler 46. The control motor 41 is detachably connected inside the support connecting rod frame 42, and the driving end of the control motor 41 is fixedly connected to the lead screw 44. The top of the connecting rod 43 is fixedly connected to the bottom of the support connecting rod frame 42. The lifting linkage frame 45 is threadedly connected to the lead screw 44, the top of the sampler 46 is rotatably connected to the outer end of the lifting linkage frame 45, and the side wall of the sampler 46 is rotatably connected to the bottom end of the connecting rod 43. Through the rotation of the control motor 41, the lead screw 44 is rotated, and then the lifting linkage frame 45 moves up and down, realizing the opening and closing of the sampler 46 and completing the sampling action. It should be noted that the number of the sampler 46 and related structures is at least two groups. Since the sampling device 4 is not the core protection point of the application, it will not be described in detail.
[0026] The auxiliary fixing device 5 is used to enhance the stability of the sampling device 4 during the rising process, preventing the measured object from falling. The auxiliary fixing device 5 comprises a driving motor 51, an auxiliary lifting device 52, an extended connecting rod 53 and a fixing cap 54. The driving motor 51 is arranged on the top surface of the middle mounting plate 12, and the driving end of the driving motor 51 is connected to the top of the auxiliary lifting device 52 through the bottom fixing plate 13. The driving end of the auxiliary lifting device 52 is connected to the top of the extended connecting rod 53, and the bottom of the extended connecting rod 53 is fixedly connected to the outer side surface of the fixing cap 54. The outer side surface of the fixing cap 54 is provided with a positioning protrusion, and the bottom surface of the bottom fixing plate 13 away from the sampling device 4 is provided with the clamping groove 131 for clamping the positioning protrusion of the fixing cap 54.
[0027] After the sampling device 4 completes sampling, the fixing cap 54 is first reset to a pre-fastening position, i.e. the fixing cap 54 is located directly below the sampler 46, at this time the driving end of the auxiliary lifting device 52 is raised, thereby driving the fixing cap 54 to be fastened to the outer side surface of the sampler 46 of the sampling device 4, thereby playing an auxiliary fixing role on the sampling device 4, preventing it from being opened due to vibration and causing the measured object to fall. Then the lifting end of the lifting driving device 2 is raised, driving the sampling device 4 to rise, at the same time the driving end of the auxiliary lifting device 52 is raised, until the top surface of the sampling device 4 abuts against the bottom surface of the bottom fixing plate 13, at this time the auxiliary lifting device 52 and the lifting driving device 2 are turned off.
[0028] This process does not need to completely synchronize the lifting speed of the auxiliary lifting device 52 and the lifting driving device 2, only the fixing cap 54 can play a role of being located directly below the sampler 46, and the fixing cap 54 can rise together, so as to avoid the measured object from falling as much as possible.
[0029] When it is necessary to start the sampling work, the auxiliary lifting device 52 is turned on, so that the fixing cap 54 is first lowered to a state away from the sampler 46, at this time the driving motor 51 is turned on to drive the auxiliary lifting device 52 to rotate, thereby driving the fixing cap 54 to rotate. The fixing cap 54 is first rotated by a certain angle, and the rotation angle here only needs to not affect the rising movement. When the positioning protrusion of the fixing cap 54 is in the same horizontal plane as the clamping groove 131, the driving motor 51 is continuously turned on, so that the positioning protrusion of the fixing cap 54 is clamped into the clamping groove 131. It should be noted that the worker only needs to close the auxiliary lifting device 52 when the fixing cap 54 is raised to the position where the top surface of the fixing cap 54 abuts against the bottom surface of the bottom fixing plate 13, and does not need to see that the positions are flush.
[0030] Working principle:
[0031] When the sampling work needs to be started, the auxiliary lifting device 52 is started to make the fixed cap 54 first lower to a state away from the sampler 46, and then the driving motor 51 is started to make the auxiliary lifting device 52 rotate and further drive the fixed cap 54 to rotate. The fixed cap 54 is first rotated by a certain angle, and the rotation angle here can be any angle that does not affect the lifting movement. When the positioning protrusion of the fixed cap 54 is in the same horizontal plane as the clamping groove 131, the driving motor 51 is continuously started to make the positioning protrusion of the fixed cap 54 clamped into the clamping groove 131.
[0032] After the sampling device 4 completes the sampling, the driving motor 51 is started to make the auxiliary lifting device 52 rotate and further drive the positioning protrusion of the fixed cap 54 to move away from the clamping groove 131, and then the auxiliary lifting device 52 is started to make the driving end of the auxiliary lifting device 52 lower by a certain depth, and then the auxiliary lifting device 52 is stopped. Then the driving motor 51 is started to make the fixed cap 54 rotate to below the sampler 46, and then the auxiliary lifting device 52 is started to make the driving end of the auxiliary lifting device 52 rise, thereby driving the fixed cap 54 to be buckled on the outer side of the sampler 46 of the sampling device 4, thereby playing an auxiliary fixing role on the sampling device 4 to prevent the sampling device 4 from being opened due to vibration and causing the measured object to fall. Then the lifting end of the lifting driving device 2 rises to drive the sampling device 4 to rise, and at the same time, the driving end of the auxiliary lifting device 52 rises until the top surface of the sampling device 4 abuts against the bottom surface of the bottom fixed plate 13, and then the auxiliary lifting device 52 and the lifting driving device 2 are stopped.
