Description

Technical Field

[0001] The invention relates to the technical field of geological sampling, and in particular to a geological content sampling device for geological surveying and mapping. Background Art

[0002] In geological surveying and mapping, it is crucial to obtain accurate geological content data. Traditional geological sampling methods often rely on manual operations, which are not only inefficient, but also difficult to ensure sampling depth and accuracy. Especially in complex geological conditions, such as hard rock or soft soil, traditional methods are even more difficult to handle. In addition.

[0003] Application No. CN202410346041.X discloses a geological content sampling device for geological surveying, including a sampling bracket, a control unit is installed on the top of the sampling bracket, and a drilling mechanism is installed below the control unit; the drilling mechanism includes a rotating part and a drilling rod, a soil discharge plate is arranged on the outside of the drilling rod, and a loose soil plate is fixed on the bottom of the drilling rod; an anti-pollution isolation component, the anti-pollution isolation component is installed on the outside of the drilling rod, and the anti-pollution isolation component includes a sampling isolation sleeve, the outer side of the soil discharge plate is fitted with the inner wall of the sampling isolation sleeve, and the top of the sampling isolation sleeve is fixed with a soil-leading isolation sleeve, and a mounting frame is installed on the inner side of the soil-leading isolation sleeve. The present invention can lead the drilled soil out of the borehole during the sampling drilling process, and the inner wall of the borehole is isolated by the sleeve so as not to be in direct contact with the drilled soil, so as to keep the soil on the inner wall of the borehole as the soil at the current depth, and collect samples from the inner wall of the borehole to ensure the accuracy of sampling.

[0004] Based on the search of the above patents and the application of existing geological content sampling devices for geological surveying and mapping, it is understood that the current geological sampling devices collect a large number of samples during the sampling process. When arriving at the sampling position of the geological layer, there is a tendency for high-layer samples to remain, resulting in inaccurate sampling at the sampling position required for geology, affecting the accuracy of the analysis results.

[0008] Furthermore, a mounting seat is fixedly installed in the middle position of the top of the lifting frame, and a motor A is fixedly installed in the middle position of the upper interior of the mounting seat. The rotating shaft of motor A is fixedly connected to the top position of screw member A. Screw member A is located in the middle position of the interior of the lifting frame, and a threaded hole is opened in the middle rear position of the lifting block, and screw member A is located in the threaded hole of the lifting block.

[0009] Furthermore, a bidirectional screw is rotatably connected to the middle position of the inner part of the clamping frame, and the left and right threads of the bidirectional screw are symmetrically designed. Threaded holes are opened at the middle and rear ends of the sides of the two clamping plates, and the left and right positions of the bidirectional screw are respectively located in the threaded holes of one clamping plate.

[0010] Furthermore, a driving motor is arranged below the drilling machine, and a rotating shaft of the driving motor of the drilling machine is fixedly connected to a middle position at the top of a transmission rotating shaft, and a casing is fixedly installed at a middle position at the bottom of the transmission rotating shaft.

[0011] Furthermore, a stabilizing shaft is fixedly provided at the bottom axis position of the transmission shaft, and the stabilizing shaft is located at an internal position of the sleeve.

[0012] Furthermore, a through hole is provided at the middle position of the bottom of the sleeve, and the middle position of the bottom of the stabilizing shaft is connected to the middle position of the top of the conical buffer block through a spring.

[0013] Furthermore, the buffer block is located below the through hole of the sleeve, the spring for stabilizing the connection between the shaft and the buffer block is located in the through hole of the sleeve, and the lower position of the sleeve is installed at the upper position inside the collecting tube.

[0014] Furthermore, a motor B is fixedly connected to the middle position of the front end of the adjustment frame, and the rotating shaft of the motor B is fixedly connected to the middle position of the top of the gear A, and the gear A meshes with the gear ring.

The soil at the sampling position first enters the interior of the sampling sleeve, and then is transferred from the middle position of the adjustment frame to the internal position of the collection tube for collection, thereby avoiding collection errors.

[0017] The drilling machine transmits power to the spiral drill bit through the transmission shaft and casing to achieve efficient drilling. At the same time, the design of the stable shaft and buffer block provides buffering and stabilization during the drilling process, ensuring the accuracy and efficiency of sampling.

This design enables the device to accurately sample at a specific depth, avoiding errors and contamination during the sampling process.

[0019] In the process of the overall upward movement of the drilling machine and the collecting tube, vibration is inevitable. The buffer block reduces the force through the spring between the buffer block and the stabilizing shaft, so that the conical position at the bottom of the buffer block fits the sampling sample. At the same time, the buffer block itself can also act as a damper. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Example: As attached Figure 1 To Attachment Figure 8 As shown: The present invention provides a geological content sampling device for geological surveying and mapping, comprising: a support frame 1; a lifting frame 101 is fixedly connected to the middle position of the top of the support frame 1, a lifting block 105 is slidably connected to the internal front end position of the lifting frame 101, a clamping frame 2 is fixedly connected to the front end position of the lifting block 105, a clamping plate 202 is respectively arranged on the left and right sides of the front end of the clamping frame 2, a drilling machine 3 is clamped and fixed at the inner sides of the two clamping plates 202, the drilling machine 3 is located just above the collecting tube 4, the screw member A104 is driven by the motor A103 to realize the up and down sliding of the lifting block 105 along the lifting frame 101, thereby adjusting the height of the drilling machine 3 and the collecting tube 4, this design enables the device to adapt to sampling needs at different heights, and improves the flexibility and adaptability of operation.

[0027] Among them, the middle and lower position of the collecting tube 4 is designed as a funnel structure, and a circular ring plate is arranged at the bottom. The circular ring plate position at the bottom of the collecting tube 4 is fixedly connected to the top position of the sampling sleeve 411. The adjusting frame 401 is fixedly installed at the middle position of the bottom of the circular ring plate at the bottom of the collecting tube 4. The adjusting frame 401 is annular in design, and the internal position of the adjusting frame 401 is rotatably connected with a gear ring 402. The bottom position of the gear ring 402 is provided with a spiral groove. The bottom position of the adjusting frame 401 is provided with four slide grooves, and the four slide grooves of the adjusting frame 401 are distributed in a cross shape. The adjusting frame A sector plate 405 is slidably connected in each slide groove of 401, and an arc groove is set in the middle position of the top of each sector plate 405. The arc grooves of the four sector plates 405 mesh with the spiral groove position at the bottom of the gear ring 402. A circular discharge hole is opened at the upper position on both sides of the sampling sleeve 411. A cross 406 is fixedly installed in the middle position inside the sampling sleeve 411, and a detachable spiral drill bit 407 is installed in the middle position at the bottom of the cross 406. The spiral drill bit 407 is located at the lower position inside the sampling sleeve 411.

[0028] Among them, a mounting base 102 is fixedly installed in the middle position of the top of the lifting frame 101, and a motor A103 is fixedly installed in the middle position of the upper inside of the mounting base 102. The rotating shaft of the motor A103 is fixedly connected to the top position of the screw member A104. The screw member A104 is located in the middle position inside the lifting frame 101. A threaded hole is opened in the middle rear position of the lifting block 105, and the screw member A104 is located in the threaded hole of the lifting block 105.

[0029] Among them, a bidirectional screw 201 is rotatably connected to the middle position inside the clamping frame 2, and the left and right threads of the bidirectional screw 201 are symmetrically designed. Threaded holes are opened at the middle and rear ends of the sides of the two clamping plates 202. The left and right positions of the bidirectional screw 201 are respectively located in the threaded holes of a clamping plate 202. The bidirectional screw 201 designed inside the clamping frame 2 can symmetrically adjust the distance between the two clamping plates 202, thereby ensuring that the drilling machine 3 is stably clamped. This design effectively prevents the drilling machine 3 from shaking and falling off during the drilling process, and improves the stability and safety of sampling.

[0030] Among them, a driving motor is arranged under the drilling machine 3, and the driving motor shaft of the drilling machine 3 is fixedly connected to the middle position of the top of the transmission shaft 301, a sleeve 302 is fixedly installed at the middle position of the bottom of the transmission shaft 301, and a stabilizing shaft 303 is fixedly arranged at the bottom axis position of the transmission shaft 301, and the stabilizing shaft 303 is located in the internal position of the sleeve 302.

[0031] Among them, a through hole is set in the middle position of the bottom of the sleeve 302, and the middle position of the bottom of the stabilizing shaft 303 is connected to the middle position of the top of the conical buffer block 304 through a spring. The buffer block 304 is located below the through hole of the sleeve 302. The spring connecting the stabilizing shaft 303 and the buffer block 304 is located in the through hole of the sleeve 302. The lower position of the sleeve 302 is installed in the upper position inside the collecting tube 4. When the soil sample does not enter the collecting tube 4, the funnel structure of the collecting tube 4 fits with the bottom position of the buffer block 304.

[0032] The front middle position of the adjusting frame 401 is fixedly connected with a motor B403 , the rotating shaft of the motor B403 is fixedly connected with the top middle position of the gear A404 , and the gear A404 meshes with the gear ring 402 .

[0033] When using: First, transfer the support frame 1 to the position just above the desired sampling area, and drive the screw member A104 to rotate through the motor A103, thereby driving the lifting block 105 to slide up and down along the lifting frame 101, thereby realizing the lifting and lowering of the clamping frame 2, and the drilling machine 3 as a whole and the collecting tube 4 as a whole can be raised and lowered in height.

[0034] When the bottom of the spiral drill bit 407 touches the ground, the drilling machine 3 drives the motor shaft to operate and drives the transmission shaft 301 to rotate. The power is transmitted through the transmission shaft 301 and the casing 302, and the collecting tube 4 rotates as a whole. The spiral drill bit 407 drills down into the ground. During the drilling process of the spiral drill bit 407, the soil sample will enter the internal position of the sampling sleeve 411, and then the collected material inside the sampling sleeve 411 will be discharged through the discharge holes designed on the upper sides of the sampling sleeve 411.

[0035] Start the motor B403, and the shaft of the motor B403 drives the gear A404 to rotate. The gear A404 is meshed with the gear ring 402 for transmission, and the four sector plates 405 slide at the bottom of the adjusting frame 401 to seal the middle position of the adjusting frame 401, so as to prevent the soil in the internal position of the sampling sleeve 411 from passing through the adjusting frame 401 and entering the internal position of the collecting tube 4 for collection.

[0036] When the sampling sleeve 411 reaches the required sampling depth, the motor B403 is controlled to drive the gear A404 to rotate in the opposite direction. The gear A404 is meshed with the gear ring 402 to transmit the four sector plates 405 to extend, canceling the closure of the bottom position of the adjustment frame 401. When sampling at a specific depth, the spiral drill bit 407 continues to drill downward to the sampling position. The soil at the sampling position first enters the interior of the sampling sleeve 411, and then is transferred from the middle position of the adjustment frame 401 to the internal position of the collection tube 4 for collection, thereby avoiding collection errors.

[0037] After the collected sample enters the collection tube 4 , the sampling sleeve 411 continues to move downward. At this time, the sample will push up the buffer block 304 until the top position of the buffer block 304 fits the bottom position of the sleeve 302 , and the sample is finally stored in the collection tube 4 .

[0038] After the sampling inside the collecting tube 4 is completed, the drilling machine 3 as a whole and the collecting tube 4 as a whole will slide upward along the lifting frame 101 through the lifting block 105 to complete the upward movement. In this process, the motor B403 shaft cooperates with the gear A404, and the gear ring 402 drives the four sector plates 405 to retract, so that every two adjacent sector plates 405 fit together, and the middle position of the adjustment frame 401 is closed to prevent the sample inside the collecting tube 4 from escaping from the collecting tube 4; in addition, there is inevitably vibration in the process of the drilling machine 3 as a whole and the collecting tube 4 as a whole moving upward. The buffer block 304 reduces the force through the spring between the stabilizing shaft 303, so that the conical position at the bottom of the buffer block 304 fits the sample, and the buffer block 304 itself can also play the role of a damper.

[0039] The above are only specific implementations of the present disclosure, but the protection scope of the present disclosure is not limited thereto, and the protection scope of the present disclosure shall be based on the protection scope of the claims.
