Detailed implementation method

[0023] Example 1: Refer to Figures 1 - 6, a green, safe and efficient mining device for mines, comprising a mounting frame 1, a lifting plate 2, a first motor 3 and a spiral blade rod 4, and further comprising a limiting cylinder 8; the mounting frame 1 is placed vertically, the lifting plate 2 moves vertically along the mounting frame 1, the first motor 3 is fixed to the top of the lifting plate 2, the output shaft of the first motor 3 extends vertically downward below the lifting plate 2, the spiral blade rod 4 is connected to the output shaft of the first motor 3, the spiral blade rod 4 extends vertically downward, spiral blades are distributed on the outer wall of the spiral blade rod 4, and a drill bit 5 is fixed to the bottom end of the spiral blade rod 4; a connecting plate 9 is arranged at the lower position of the mounting frame 1, the limiting cylinder 8 is connected to one end of the connecting plate 9 facing the spiral blade rod 4, and the outer wall of the spiral blade rod 4 is in sliding contact with the inner wall of the limiting cylinder 8. During use, the mounting frame 1 is fixed to the ground, and the first motor 3 drives the spiral blade rod 4 and the drill bit 5 to rotate, so that the spiral blade rod 4 and the drill bit 5 descend along with the lifting plate 2 to carry out drilling and mining operations; in the prior art, the spiral blade rod 4 may conduct mechanical vibrations through the lifting plate 2 during long-term operation, causing the top of the mounting frame 1 to deflect outward, resulting in the deflection of the spiral blade rod 4 and the drill bit 5 and affecting the drilling and mining operations. In the technical solution of the present application, the limiting cylinder 8 is located at the opening position close to the ground, and the limiting cylinder 8 is connected to the bottom of the mounting frame 1 through the connecting plate 9. At the same time, the inner wall of the limiting cylinder 8 is in sliding contact with the outer wall of the descending spiral blade rod 4; thus, during use, on the one hand, the stability of the spiral blade rod 4 is improved by the wrapping operation of the outer wall of the spiral blade rod 4 by the limiting cylinder 8 and the bottom end of the limiting cylinder 8 being in contact with the ground, and the means of stabilizing the spiral blade rod 4 does not solely depend on the fixed connection position of the first motor 3, so as to improve the stable anti-deflection effect of the spiral blade rod 4 during operation through the fixation at two positions; on the other hand, since the bottom end of the mounting frame 1 is in contact with the ground, when the lifting plate 2 above vibrates and deflects and applies a force outward, the top of the mounting frame 1 will tilt outward, and when the connecting plate 9 at the bottom vibrates and deflects and applies a force outward, the top of the mounting frame 1 will tilt inward. Thus, when the spiral blade rod 4 deflects, the lifting plate 2 and the connecting plate 9 will apply forces to the mounting frame 1 simultaneously, and the lifting plate 2 and the connecting plate 9 will produce a way of applying forces that makes the mounting frame 1 tilt in different directions to offset the acting forces, thereby improving the stability and anti-deflection effect of drilling and mining.

[0024] In the present invention, with reference to Figures 1 - 6, a movable cavity 101 is provided in the mounting bracket 1. Vertical extension limiting grooves 102 are provided at both ends of the movable cavity 101. The limiting grooves 102 are horizontally penetrated. A vertically extending threaded rod 6 is rotatably connected between the top inner wall and the bottom inner wall of the movable cavity 101. The top end of the threaded rod 6 is drivingly connected to a second motor 7. One end of the lifting plate 2 is provided with a movable block 201 that is limited and slides in the movable cavity 101. One end of the connecting plate 9 is provided with a slider 901 that is limited and slides in the movable cavity 101. Both the movable block 201 and the slider 901 are provided with a middle part and limiting parts located at both ends of the middle part. The width of the middle part is greater than the width of the limiting part. The outer wall of the limiting part is in sliding contact with the inner wall of the limiting groove 102. The movable block 201 is provided with a threaded hole that is threadedly connected to the threaded rod 6. The slider 901 is provided with a through hole with a diameter larger than the outer diameter of the threaded rod 6. A first spring 10 is connected between the movable block 201 and the slider 901. Through the threaded connection between the movable block 201 and the threaded rod 6, the lifting operation of the lifting plate 2 with the spiral blade rod 4 is realized. Through the connection between the slider 901 and the first spring 10, the bottom end of the limiting cylinder 8 is tightly pressed against the ground to improve the stability and anti-offset effect of the spiral blade rod 4.

[0025] In the present invention, referring to Figures 1 - 6 , the limiting cylinder 8 is provided with a guiding part, a connecting part and an inserting part from top to bottom. The inner diameters of the guiding part, the connecting part and the inserting part are the same. The outer diameter of the inserting part gradually decreases from top to bottom, so that the bottom end of the inserting part is inserted into the opening position at the top of the ground drill hole under the action of the first spring 10, and the outer wall inclined surface of the inserting part abuts against the inner wall of the top opening of the drill hole. On the one hand, the stability of the limiting cylinder 8 is improved to improve the stability of the limit on the spiral blade rod 4. On the other hand, by the limiting cylinder 8 abutting against the top opening of the drill hole, the stability around the hole is improved to avoid the offset of the spiral blade rod 4 caused by the collapse of the hole opening; the outer diameter of the guiding part gradually increases from top to bottom, and the inner wall of the guiding part fits with the spiral blade rod 4, so that the part of the soil brought out by the spiral blade rod 4 is dispersed along the outer wall of the guiding part under the action of gravity when it separates from the inner wall of the guiding part.

[0026] In the present invention, referring to Figures 1 - 6 , one end of the connecting plate 9 is fixed with a horizontally placed connecting cylinder 11. One end of the limiting cylinder 8 is provided with a horizontally placed connecting rod 12. The outer wall of the connecting rod 12 is in sliding contact with the inner wall of the connecting cylinder 11. A second spring is connected between one end of the connecting rod 12 and the connecting cylinder 11. The connecting cylinder 11 and the connecting rod 12 are used to connect the connecting plate 9 and the limiting cylinder 8, and the horizontal vibration amplitude transmitted to the limiting cylinder 8 is reduced by using the connecting rod 12 and the second spring, so as to buffer the mechanical vibration, so as to avoid the excessive offset of the spiral blade rod 4 due to mechanical vibration and affect the drilling and mining operation effect.

[0027] In the present invention, referring to Figures 1 - 6, on both sides of one end of the mounting frame 1 close to the lifting plate 2, baffles 13 are installed. The bottom end of the baffle 13 is flush with the bottom end of the mounting frame 1. The horizontal cross-section of the baffle 13 is set as an arc structure with the middle position arched towards the lifting plate 2. The two sides of the lifting plate 2 are in sliding contact with the two baffles 13. On the one hand, the baffles 13 distributed at both sides block the dust during the drilling and mining process, avoiding excessive scattering of dust and affecting the working environment. On the other hand, by contacting the two sides of the lifting plate 2 with the arc-shaped baffles 13, the mechanical vibration is dispersed to improve the stability of the overall installation of the mounting frame 1 and the baffle 13 on the ground for use.

[0028] Embodiment 2: Refer to Figures 1 - 8 , a green, safe and efficient mining device for mines. On the basis of Embodiment 1, a fixing plate 14 is installed at the top end of the connecting plate 9. The two sides of the fixing plate 14 are in sliding contact with the outer walls of the baffles 13. Horizontally placed dust collection pipes 15 are installed at both sides of the fixing plate 14. The extending direction of the dust collection pipes 15 is perpendicular to the end face of the mounting frame 1. One end of the dust collection pipe 15 close to the mounting frame 1 is communicated with a horizontally placed air suction pipe 16. The air suction pipe 16 is perpendicular to the dust collection pipe 15. A vertically extending through groove 131 is opened at the position of the baffle 13 corresponding to the air suction pipe 16. A plurality of air holes 151 are opened on the side and bottom of the dust collection pipe 15 facing the spiral blade rod 4. During the use process, through the installation of the fixing plate 14 and the connecting plate 9, the dust collection pipe 15 moves along with the connecting plate 9 and the dust collection pipe 15 is always located above the limiting cylinder 8. And during the drilling and mining process, the suction operation of the air suction pipe 16 makes the air holes 151 on the dust collection pipe 15 generate suction force, so as to absorb the dust during the process of the spiral blade rod 4 sending out the soil, thereby reducing the impact on the working environment.

[0029] In the present invention, refer to Figures 1 - 8, one end of the dust collection pipe 15 far from the suction pipe 16 is connected with a swing air pipe 17. The swing air pipe 17 is vertically arranged. A horizontally extending pipe joint 171 is arranged at the top end of the swing air pipe 17. The pipe joint 171 is rotatably connected to the end of the dust collection pipe 15. A vertically extending air groove 172 is opened at the middle position of the swing air pipe 17 far from the baffle 13. A plurality of vertically distributed air holes 173 are opened at both ends of the swing air pipe 17. Wind blades 18 are fixed at positions on the inner wall of the swing air pipe 17 corresponding to the air holes 173. During the suction process of the suction pipe 16, the dust collection pipe 15 performs dust suction operations on both sides of the spiral leaf rod 4. The air grooves 172 on both sides of the swing air pipes 17 perform dust suction operations on the end position of the spiral leaf rod 4 far from the mounting frame 1. The air holes 173 at both ends of the swing air pipe 17 perform air extraction and, as the dust distribution near the spiral leaf rod 4 changes, the intensity of the dust hitting the wind blades 18 when entering the interior from both ends of the swing air pipe 17 is different, so that the swing air pipe 17 swings under the condition of different external dust distributions. The swing of the swing air pipe 17 is used to improve the dynamic change of the suction of the dust and improve the dust reduction effect and avoid the blockage of the air holes 173.

[0030] Embodiment 3: Refer to Figures 1 - 8 , a green, safe and efficient mining device for mines. On the basis of Embodiment 2, a barometric pressure monitoring module is arranged in the dust collection pipe 15. The barometric pressure monitoring module is used to monitor the barometric pressure intensity at the connection position between the dust collection pipe 15 and the suction pipe 16 in real time. When the spiral leaf rod 4 deflects, the gap between one side of the spiral leaf rod 4 and the drill hole will increase, so that local dust will increase during the continuous movement of the spiral leaf rod 4. The increase in dust will cause more dust to be sucked in the dust collection pipe 15, resulting in an increase in resistance or blockage of the air holes 151, both of which will cause the barometric pressure intensity in the dust collection pipe 15 to decrease; a squeezing force monitoring module is arranged in the connecting cylinder 11. The squeezing force monitoring module is used to monitor the squeezing force of the second spring in real time. If the spiral leaf rod 4 deflects, it will pull or push the connecting rod 12, causing the second spring to be over-squeezed or over-stretched, that is, the squeezing force will exceed the expected change; there is also a current monitoring module. The current monitoring module is used to monitor the current magnitude of the first motor 3 in real time. If the spiral leaf rod 4 deflects and the outer wall of the spiral leaf rod 4 is blocked, it will suddenly increase, resulting in a sudden increase in the current.

[0031] In the present invention, the barometric pressure monitoring module, the squeezing force monitoring module and the current monitoring module are uploaded to the processor. After calculation, an early warning coefficient is obtained, and the early warning coefficient is compared with the early warning reference coefficient. If the early warning coefficient is less than or equal to the early warning reference coefficient, it means that the spiral leaf rod 4 is in a normal working state. If the early warning coefficient is greater than the early warning reference coefficient, it means that the deflection of the spiral leaf rod 4 exceeds the expectation and affects the drilling and mining operation, and the staff needs to be reminded.

[0032] In the present invention, the calculation logic of the early warning coefficient is: Step 1: The air pressure monitoring module obtains the air pressure intensity , the extrusion force monitoring module obtains the extrusion force , the current monitoring module obtains the current value ; Step 2: Calculate the air pressure deviation ratio , , where in the formula is the air pressure intensity under normal conditions; Calculate the extrusion force deviation ratio , , where in the formula is the extrusion force under normal conditions; Calculate the current deviation ratio , , where the current change range during normal operation is , means to select and the maximum value of; Step 3: Calculate the warning coefficient , , where in the formula , and are weight coefficients, which can be determined in advance through experiments, and , is the time decay factor of the air pressure deviation ratio, is the time decay factor of the extrusion force deviation ratio, which can be determined in advance through experiments, and , represents the time step of data acquisition. By introducing the decay factor, the accuracy of the analysis and calculation of the changes of air pressure intensity and extrusion force over time can be improved, represents the correlation coefficient between the extrusion force and the current, which can be determined in advance through experiments. By introducing the correlation coefficient, the coordination of the changes of the extrusion force and the current can be improved, thereby improving the accuracy of the warning; thus, by monitoring and analyzing the changes of the air pressure intensity during dust collection, the extrusion force changes in the telescopic rod, and the current changes of the rotational drive, the accuracy and timeliness of the judgment of the inclination and offset changes of the spiral blade rod 4 can be effectively improved, and the stability and efficiency of the drilling and mining can be improved.

[0033] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
