Description

Technical Field

[0001] The invention relates to the technical field of mine geology, and more particularly to a mobile drilling sampling device for an open-pit coal mine. Background Art

[0002] Coal mine sampling is to take a small part of representative samples from the coal seam for analysis, testing and identification according to certain specifications and requirements. The purpose of coal seam sampling is to determine the type of coal, coal quality characteristics and its changing laws and coal process performance of the mineable coal seam in the mining area or well field through the data obtained from the chemical and physical tests of coal samples, so as to correctly evaluate the coal quality, determine the processing technology characteristics and industrial utilization direction of coal, and provide reliable coal quality data for the development and rational utilization of coal resources.

[0003] However, in the actual mining and sampling process of open-pit coal mines, due to the characteristics of open-pit coal mines being exposed to the natural environment, there are many impurities on the surface of the coal mines. The drilling sampling equipment currently used in open-pit coal mines is easily contaminated by impurities on the surface of the coal seam and the soil layer during the drilling process, resulting in a large amount of impurities mixed into the samples taken out, reducing the purity of the samples. This not only increases the difficulty of subsequent sample processing, but also affects the accurate evaluation of coal seam characteristics.

[0004] Solving the purity problem usually requires multiple steps, such as cleaning the soil layer, impurities, and locating the drilling position, which are cumbersome and time-consuming. In addition, the poor mobility of the equipment leads to inefficiency when transferring between different sampling points, further affecting the overall sampling progress. Based on the above problems, it is particularly important to develop an efficient mobile open-pit coal mine drilling sampling equipment. In view of this, we propose a mobile drilling sampling equipment for open-pit coal mines. Summary of the invention

At this time, push the plunger to move downward on the slot, the plunger drives the collar, and the collar drives the first chuck, the connecting rod and the second chuck to move downward until the third groove at the bottom of the second chuck is fixedly engaged with the first groove at the top of the toothed disc. At this time, slide the paddle block in the slide slot again to the very end. At this time, when the drill rod drives the toothed disc to rotate, the first groove at the top of the toothed disc is fixedly engaged with the third groove at the bottom of the second chuck, thereby synchronously driving the first chuck, the connecting rod and the second chuck to rotate. Since the connecting rod is movable The outer ring frame is inserted on the outer ring frame, so it drives the outer ring frame to rotate synchronously. At this time, the drill rod, the gear plate and the outer ring frame revolve as a whole, and the outer ring frame drives the arc plate at the bottom and the drill barrel to rotate as a whole to perform drilling operations; when the drill barrel rotates clockwise, due to the friction force generated by the coal mine soil layer on the bottom surface of the opening and closing fan plate and the resistance generated on the side of the opening and closing fan plate, the opening and closing fan plate is stationary relative to the coal mine layer, and the drill barrel rotates clockwise. When the blocking block set on the opening and closing fan plate contacts the edge of the entry slot, the opening and closing fan plate and the drill barrel are relatively stationary. At this time, the drill barrel drives the opening and closing fan plate to rotate at the same time, so that the entry slot is in an open state, and the coal follows the rotation to enter the inside of the drill barrel; S3, discarded layer synchronous exclusion operation; The sliding paddle card block slides in the slide groove until it slides onto the slot. At this time, the insertion rod is pushed to move toward the middle of the slot. The insertion rod drives the collar, and the collar drives the first chuck, the connecting rod and the second chuck to move toward the middle until it moves to the middle slide groove position. At this time, the sliding paddle card block slides in the middle slide groove to the very end again; when the drill rod drives the toothed disc to rotate, the toothed disc engages with the gear to drive the gear to rotate, and the gear engages with the inner tooth groove on the inner wall of the outer ring frame on the outside, so that the toothed disc drives the gear to rotate, and the gear drives the inner tooth groove to make the outer ring frame rotate. At this time, the gear and the outer ring frame are both rotating on their own. In this state, the outer ring frame drives the arc plate and the drill barrel at the bottom to rotate, so as to produce drilling in the coal mine, the gear drives the first shaft body fixedly connected at the bottom end thereof to rotate, the first shaft body drives the belt to rotate, the belt pulls the second shaft body connected at the other end to rotate at the bottom end of the toothed disc, the second shaft body synchronously drives the fixedly connected shaft rod to rotate, the shaft rod drives the auger to rotate synchronously inside the drill barrel, so that in the process of the drill barrel rotating through the entry slot to drill a hole, the coal mine enters the inside of the drill barrel through the entry slot, and then through the synchronous rotation of the auger, the top layer of coal mine and impurities that first enter the drill barrel are discharged through the rotation of the auger; S4, sampling operation; When sampling is required, first slide the pick card block in the slide groove until it slides to the slot.

At this time, slide the pick card block in the slide groove again to the end. Fig.13 As shown, at this time, when the drill rod drives the toothed disc to rotate, since the second slot opened at the bottom of the fixed frame is fixedly engaged with the third slot opened at the top of the first chuck, the connecting rod is movably inserted on the outer ring frame, so the outer ring frame is fixed, and the rotation of the toothed disc drives the gear meshing on its outer wall to rotate, and the gear is also meshed on the inner tooth groove of the outer ring frame, but because the outer ring frame is in a fixed state at this time, the gear makes a circular arc motion along the inner tooth groove of the outer ring frame, and the outer ring frame is fixed, resulting in the arc plate and the drill barrel being fixed, and the rotation of the gear drives the first shaft body fixedly connected to its bottom end to rotate, and the first shaft body drives the belt to rotate, and the belt pulls the second shaft body connected at the other end to rotate at the bottom of the toothed disc, and the second shaft body synchronously drives the fixedly connected shaft rod to rotate, and the shaft rod drives the auger to rotate inside the drill barrel, thereby realizing the sampling state of the auger rotating alone, and taking out the coal mine sample taken from the drill barrel.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention improves the structure of the existing coal mine drilling and sampling equipment by arranging a moving crawler at the bottom of a hydraulic platform, arranging a longitudinal moving mechanism at the front end of the hydraulic platform, arranging a support frame on the longitudinal moving mechanism, arranging a vertical calibration platform on the support frame, hoisting the drilling and sampling mechanism on the longitudinal moving mechanism, driving the drilling and sampling mechanism to drill into the coal mine layer through the longitudinal moving mechanism, and arranging a mode adjustment mechanism on the vertical calibration platform to adjust the specific use state of the drilling and sampling mechanism.

[0017] 2. In the present invention, a toothed disc is fixedly connected to the bottom end of the drill rod. The toothed disc is a toothed disc with meshing teeth on the outer wall. The first slot is opened at the top of the toothed disc. When the drill rod drives the toothed disc to rotate, the toothed disc meshes with the gear to drive the gear to rotate. The gear meshes with the inner tooth groove on the inner wall of the outer ring frame on the outside, so that the toothed disc drives the gear to rotate, and the gear drives the inner tooth groove to rotate the outer ring frame. At this time, the gear and the outer ring frame are both in a state of self-rotation. The outer ring frame drives the arc plate and the drill barrel at the bottom to rotate, so as to drill into the coal mine. The gear drives the first shaft body fixedly connected to its bottom end to rotate. The first shaft body The belt is driven to rotate, and the belt pulls the second shaft body connected to the other end to rotate at the bottom end of the toothed disk. The second shaft body synchronously drives the fixedly connected shaft rod to rotate, and the shaft rod drives the auger to rotate synchronously inside the drill barrel, so that in the process of the drill barrel rotating through the entry slot to drill a hole in the present invention, the coal enters the drill barrel through the entry slot, and then the top layer of coal and impurities that first enter the drill barrel are discharged through the rotation of the auger through the synchronous rotation of the auger. The introduction of the waste layer exclusion state avoids the mixing of waste layer materials during the sampling process, thereby improving the sampling accuracy and the accuracy of subsequent analysis.

[0018] 3. In the present invention, a rotating shaft is rotatably provided on the shaft hole opened at the bottom of the drill tube, and an opening and closing fan plate is fixedly and symmetrically provided on the rotating shaft. When the drill tube rotates clockwise, as shown in the attached Fig.11 As shown, due to the friction force generated by the coal mine soil layer on the bottom surface of the opening and closing fan plate and the resistance generated on the side of the opening and closing fan plate, the opening and closing fan plate is stationary relative to the coal mine layer, and the drill barrel rotates clockwise. When the blocking block set on the opening and closing fan plate contacts the edge of the entry groove, the opening and closing fan plate and the drill barrel are relatively stationary. At this time, the drill barrel drives the opening and closing fan plate to rotate at the same time, so that the entry groove is in an open state, which is convenient for entering the coal mine; when the drill barrel rotates counterclockwise, due to the friction force generated by the coal mine soil layer on the bottom surface of the opening and closing fan plate and the resistance generated on the side of the opening and closing fan plate, the opening and closing fan plate is stationary relative to the coal mine layer, and the drill barrel rotates counterclockwise. When the blocking block set on the opening and closing fan plate contacts the edge of the entry groove, the opening and closing fan plate and the drill barrel are relatively stationary, so that they are in a closed state, thereby simplifying the sampling process and further improving the efficiency of the sampling operation.

[0019] 4. In the present invention, a fixing frame is fixed on the vertical calibration table, and an insertion rod is movably inserted on the fixing frame. When the state of the drilling sampling mechanism needs to be adjusted, if the drilling state is required, the sliding paddle block slides in the slide groove until it slides to the slot. At this time, the insertion rod is pushed to move downward on the slot, and the insertion rod drives the collar, and the collar drives the first chuck, the connecting rod and the second chuck to move downward until the third groove opened at the bottom end of the second chuck is fixedly engaged with the first groove opened at the top end of the toothed disc. At this time, the sliding paddle block slides in the slide groove to the end again. Fig.14 As shown, at this time, when the drill rod drives the toothed disc to rotate, since the first groove opened at the top of the toothed disc is fixedly engaged with the third groove opened at the bottom of the second chuck, the first chuck, the connecting rod and the second chuck are synchronously driven to rotate. Since the connecting rod is movably inserted in the outer ring frame, the outer ring frame is synchronously driven to rotate. At this time, the drill rod, the toothed disc and the outer ring frame revolve as a whole, and the outer ring frame drives the arc plate and the drill tube at the bottom to rotate as a whole to perform drilling operations; if the sampling state is required, the sliding paddle block slides in the slide groove until it slides to the slot, and at this time, the insertion rod is pushed to move upward on the slot, and the insertion rod drives the ring, and the ring drives the first chuck, the connecting rod and the second chuck to move upward until the third groove opened at the top of the first chuck is fixedly engaged with the second groove opened at the bottom of the fixed frame. At this time, the sliding paddle block slides in the slide groove to the very end again, as shown in FIG. Fig.13 As shown, at this time, when the drill rod drives the toothed disc to rotate, since the second slot opened at the bottom of the fixed frame is fixedly engaged with the third slot opened at the top of the first chuck, the connecting rod is movably inserted on the outer ring frame, so the outer ring frame is fixed, and the rotation of the toothed disc drives the gear meshing on its outer wall to rotate, and the gear is also meshed on the inner tooth groove of the outer ring frame, but because the outer ring frame is in a fixed state at this time, the gear makes a circular arc motion along the inner tooth groove of the outer ring frame, and the outer ring frame is fixed, resulting in the arc plate and the drill barrel being fixed, and the rotation of the gear drives the first shaft body fixedly connected to its bottom end to rotate, and the first shaft body drives the belt to rotate, and the belt pulls the second shaft body connected at the other end to rotate at the bottom of the toothed disc, and the second shaft body synchronously drives the fixedly connected shaft rod to rotate, and the shaft rod drives the auger to rotate inside the drill barrel, so as to realize the sampling state of the auger rotating alone; it is beneficial to reduce the idling and ineffective working time of the equipment, improve efficiency, and also help to reduce energy consumption and emissions, responding to energy conservation and emission reduction.

The second shaft (6031) ) synchronously drives the fixedly connected shaft (6032) to rotate, and the shaft (6032) drives the auger (6033) to rotate synchronously inside the drill barrel (6022), so that when the drill barrel (6022) of the present invention rotates through the entry slot (6023) to drill a hole, the coal enters the drill barrel (6022) through the entry slot (6023), and then the auger (6033) synchronously rotates so that the top layer of coal and impurities that first enter the drill barrel (6022) are discharged through the rotation of the auger (6033); S4, sampling operation; When sampling is required, the sliding pick block (7027) is first slid in the slide groove (7014) until it slides onto the slot (7013). At this time, the insertion rod (7026) is pushed to move upward on the slot (7013). The insertion rod (7026) drives the ring (7025), and the ring (7025) drives the first chuck (7021), the connecting rod (7024) and the second chuck (7022) to move upward until the third slot (7023) opened at the top of the first chuck (7021) and the bottom of the fixing frame (7011) are aligned. At this time, the slide plate block (7027) is slid again in the slide groove (7014) to the end, as shown in FIG13 . At this time, when the drill rod (606) drives the toothed disc (6011) to rotate, the second slot (7012) opened at the bottom end of the fixed frame (7011) and the third slot (7023) opened at the top end of the first chuck (7021) are fixedly engaged, and the connecting rod (7024) is movably inserted on the outer ring frame (6013), so the outer ring frame (6013) ) is fixed, the gear plate (6011) rotates to drive the gear (6015) meshed with the outer wall thereof to rotate, and the gear (6015) is also meshed with the inner tooth groove (6014) of the outer ring frame (6013), but because the outer ring frame (6013) is in a fixed state at this time, the gear (6015) moves in a circular arc along the inner tooth groove (6014) of the outer ring frame (6013), and the outer ring frame (6013) is fixed, resulting in the arc plate (6021) and the drill tube (6022) being fixed, and the gear (6015) rotates to drive the fixedly connected bottom end thereof The first shaft (6016) rotates, and the first shaft (6016) drives the belt (6017) to rotate. The belt (6017) pulls the second shaft (6031) connected at the other end to rotate at the bottom end of the toothed disc (6011). The second shaft (6031) synchronously drives the fixedly connected shaft (6032) to rotate. The shaft (6032) drives the auger (6033) to rotate inside the drill tube (6022), thereby realizing the sampling state of the auger (6033) rotating independently, and taking out the coal sample taken from the drill tube (6022).
