Description

Technical Field

[0001] The invention relates to the technical field of coal mine excavation, in particular to fast excavation drilling equipment for deep well close-range coal seam mining. Background Art

[0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. The efficient advancement of deep well and close-range coal seam mining is inseparable from the strong support of fast excavation drilling equipment.

[0003] When drilling, existing drilling equipment generates a large amount of dust while drilling out the soil. Generally, a dust suction mechanism is provided to absorb the generated dust from above, and the dust suction mechanism needs to be at a certain distance from the ground to avoid contact with the soil. However, since the soil gradually increases during drilling, the soil near the drill hole needs to be removed in time. During the soil removal process, holes need to be reserved on the side, which causes the dust to be discharged from the holes reserved on the side, thereby reducing the dust suction effect. For this reason, we disclose deep well close-range coal seam mining rapid excavation drilling equipment. Summary of the invention

[0015] Compared with the prior art, the present invention provides a rapid tunneling drilling equipment for deep well and close-distance coal seam mining, which has the following beneficial effects: In the present invention, during drilling, the equipment is placed at the position where drilling is required, and drilling can be carried out by starting the drilling mechanism. Through the rotating sleeve, the dust generated by drilling can only overflow directly upward. Starting the dust suction mechanism facilitates the adsorption of the dust that overflows directly upward. At the same time, the dust suction mechanism improves the adsorption effect under the influence of the drilling mechanism. When the drilling mechanism drills, it will drive the one-way transmission mechanism, and the one-way transmission mechanism will make the rotating sleeve and the soil guiding plate rotate. The soil guiding plate rotates to discharge the soil by the sealed discharging mechanism, so that the soil will not accumulate in the rotating sleeve.

[0016] In the present invention, when the swing rod contacts the pressure-receiving rod, the swing rod squeezes the pressure-receiving rod, so that the pressure-receiving rod rotates. The rotation of the pressure-receiving rod makes the rotating ring and the mounting sleeve rotate. The rotation of the mounting sleeve causes the mounting spring to deform. When the pressure-receiving rod separates from the swing rod, at this time, under the action of the mounting spring, the mounting sleeve and the rotating ring return to their original states, so that the rotating ring rotates back and forth, and further makes the plurality of suction heads rotate back and forth to adsorb the dust back and forth.

[0017] In the present invention, when the soil guided by the soil guiding plate enters the discharge chute, since the rotating cylinder rotates clockwise, the rotation of the rotating cylinder drives the plurality of soil scraping plates to rotate. The rotation of the plurality of soil scraping plates drives the plurality of extrusion rods and extrusion wheels to rotate. When the extrusion wheel contacts the side of the extrusion triangular plate, the side of the extrusion triangular plate will squeeze the extrusion wheel, so that the extrusion wheel moves. The movement of the extrusion wheel drives the extrusion rod and the soil scraping plate to move. The movement of the soil scraping plate makes the two reset rods enter the two reset grooves, and the two reset springs deform until the extrusion wheel reaches the arc groove on the baffle. At this time, the position of the extrusion wheel remains unchanged. When the extrusion wheel separates from the arc groove, under the reaction force of the two reset springs, the soil scraping plate returns to its original state, so that when the soil scraping plate is about to reach the position of the arc block, it will shrink into the plate groove to avoid entering, and at the same time, prevent the soil from being brought into the rotating sleeve. When the soil scraping plate leaves the position of the arc block, the soil scraping plate will return to its original state, so that the soil guided by the soil guiding plate can be scraped away. At the same time, the side of at least one soil scraping plate contacts the arc-shaped inner wall of the soil scraping plate, so that the dust will not overflow a large amount through the discharge chute.

[0020] The present invention will be further described below in conjunction with specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention necessarily goes beyond these limited embodiments. For some equivalent replacement schemes or common means, no detailed description will be given herein, but they still fall within the protection scope of this application.

[0021] Figures 1 to 13 is the best embodiment of the present invention. The following will further describe the present invention in conjunction with the attached Figures 1 to 13 to further describe the present invention.

[0022] The present invention discloses a rapid tunneling drilling equipment for deep well and close-distance coal seam mining, including a base 20. A drilling mechanism and a dust suction mechanism are installed on the top of the base 20. The dust suction mechanism is cooperatively installed with the drilling mechanism. A rotating sleeve 25 is rotatably installed at the bottom of the base 20. The rotating sleeve 25 is cooperatively installed with the drilling mechanism through a one-way transmission mechanism. A soil guiding plate 28 is fixedly installed on the inner wall of the rotating sleeve 25. A sealed discharging mechanism is installed on the rotating sleeve 25. The soil guiding plate 28 corresponds to the positions of the drilling mechanism and the sealed discharging mechanism. The sealed discharging mechanism is cooperatively installed with the one-way transmission mechanism.

[0023] With the above structure: during drilling, the equipment is placed at the position where drilling is required. By starting the drilling mechanism, drilling can be carried out. Through the rotating sleeve 25, the dust generated by drilling can only overflow directly upward. Starting the dust suction mechanism facilitates the adsorption of the dust that overflows directly upward. At the same time, the dust suction mechanism improves the adsorption effect under the influence of the drilling mechanism. When the drilling mechanism drills, it will drive the one-way transmission mechanism, and the one-way transmission mechanism will cause the rotating sleeve 25 and the soil guiding plate 28 to rotate. The soil guiding plate 28 rotates to discharge the soil by the sealed discharging mechanism, so that the soil will not accumulate in the rotating sleeve 25.

[0024] Such as Figure 1As shown in the figure, the drilling mechanism includes a U-shaped plate 5 fixedly installed on the top of the base 20. A first motor 1 is fixedly installed on the top of the U-shaped plate 5. The output shaft of the first motor 1 penetrates through the top of the U-shaped plate 5 and is fixedly installed with a rotating shaft 8. An external thread 3 is provided on the rotating shaft 8. The top inner wall of the U-shaped plate 5 and the top of the base 20 are fixedly installed with guide rods 10. Two moving blocks 4 are arranged inside the U-shaped plate 5. One of the moving blocks 4 is slidably sleeved on the guide rod 10, and the other moving block 4 is threadedly installed on the external thread 3. The side parts of the two moving blocks 4 close to each other are fixedly installed with a mounting plate 11. A second motor 2 is fixedly installed on the top of the mounting plate 11. The output shaft of the second motor 2 penetrates through the top of the mounting plate 11 and is fixedly installed with a drill rod 6. An avoidance hole corresponding to the drill rod 6 is provided on the top of the base 20. Starting the second motor 2 causes the output shaft of the drill rod 6 to rotate. At the same time, starting the first motor 1 causes the rotating shaft 8 and the external thread 3 to rotate counterclockwise. The rotation of the external thread 3 causes the moving block 4 to move downward, thereby causing the mounting plate 11, the second motor 2, and the drill rod 6 to move downward. After the drill rod 6 passes through the avoidance hole of the base 20, drilling can be carried out.

[0025] As Figure 2 , Figure 3 and Figure 4 shown in the figure, the dust suction mechanism includes a rotating ring 17 rotatably installed on the top of the base 20. The avoidance hole is located inside the rotating ring 17. The top of the rotating ring 17 is fixedly installed with a mounting ring 14 through a plurality of connecting rods. An annular pipe 18 is arranged on the outer side of the rotating ring 17. A plurality of communicating mounting pipes 15 are fixedly installed on the top of the annular pipe 18. The ends of the plurality of mounting pipes 15 far from the annular pipe 18 are fixedly installed with suction heads 16. The plurality of suction heads 16 are all fixedly connected to the outer side of the mounting ring 14. The positions of the plurality of suction heads 16 correspond to the avoidance hole. One side of the U-shaped plate 5 is fixedly installed with a filter box 23. A suction pump 22 is fixedly installed on one side of the filter box 23. The intake end of the suction pump 22 is communicated with the filter box 23. The filter box 23 is communicated with the annular pipe 18 through a connecting hose 19. A filter screen 24 is fixedly installed on the inner wall of the filter box 23. Starting the suction pump 22 can generate suction, so that the dust discharged from the avoidance hole can be inhaled into the annular pipe 18 through the plurality of suction heads 16 and the plurality of mounting pipes 15, and inhaled into the filter box 23 through the connecting hose 19. The dust can be filtered by the filter screen 24.

[0026] As Figure 1 and Figure 2As shown, the dust suction mechanism further includes a mounting sleeve 13 rotatably mounted on the top of the rotating ring 17. A movable ring 21 is rotatably sleeved on the guide rod 10. Mounting springs 12 are fixedly installed on the side portions of the movable ring 21 and the mounting sleeve 13 close to each other. A plurality of swing rods 7 are fixedly sleeved on the rotating shaft 8. A pressure-receiving rod 9 is fixedly installed on the top of the rotating ring 17. The positions of the plurality of swing rods 7 correspond to those of the pressure-receiving rod 9. When the swing rod 7 contacts the pressure-receiving rod 9, the swing rod 7 presses the pressure-receiving rod 9, causing the pressure-receiving rod 9 to rotate. The rotation of the pressure-receiving rod 9 causes the rotating ring 17 and the mounting sleeve 13 to rotate. The rotation of the mounting sleeve 13 causes the mounting springs 12 to deform. When the pressure-receiving rod 9 is separated from the swing rod 7, at this time, under the action of the mounting springs 12, the mounting sleeve 13 and the rotating ring 17 return to their original states, causing the rotating ring 17 to rotate back and forth, and further causing the plurality of suction heads 16 to rotate back and forth to adsorb dust back and forth.

[0027] As Figure 6 and Figure 7 shown, the one-way transmission mechanism includes a circular hole opened on the top of the base 20. The bottom end of the rotating shaft 8 passes through the circular hole. An outer gear ring 29 coaxially arranged with the rotating shaft 8 is rotatably mounted on the bottom of the base 20. A right-angled triangular block 31 is fixedly installed on the inner wall of the outer gear ring 29. The inclined side portion of the right-angled triangular block 31 faces the counterclockwise rotation direction of the outer gear ring 29. The bottom end and the annular side portion of the rotating shaft 8 are provided with the same groove. A sliding groove is opened on the vertical inner wall of the groove. A moving column 34 is slidably mounted in the sliding groove. One end of the moving column 34 extends out of the groove and is rotatably mounted with a moving wheel 33. The other end of the moving column 34 is fixedly connected with the inner wall of the sliding groove through a moving spring 32. The moving wheel 33 is adapted to the groove. The moving wheel 33 contacts the vertical side portion of the right-angled triangular block 31. When the rotating shaft 8 rotates counterclockwise, the rotation of the rotating shaft 8 counterclockwise causes the moving wheel 33 to rotate. The moving wheel 33 presses the vertical side portion of the right-angled triangular block 31, causing the outer gear ring 29 to rotate. When the rotating shaft 8 rotates clockwise, the inclined side portion of the right-angled triangular block 31 contacts the moving wheel 33. However, when the pressing wheel 41 on the rotating cylinder 45 rotates counterclockwise and contacts the side portion of the baffle 39, it will be stuck, causing the meshing teeth 30 and the outer gear ring 29 to be unable to rotate. Further, the moving wheel 33 is pressed by the inclined side portion of the right-angled triangular block 31 to make way, and the moving spring 32 deforms. After the avoidance is completed, under the action of the moving spring 32, the moving wheel 33 returns to its original state.

[0028] As Figure 8 , Figure 9 and Figure 10As shown, the sealed discharging mechanism includes a plurality of evenly arranged meshing teeth 30 fixedly installed on the annular side of the rotating sleeve 25. The plurality of meshing teeth 30 are meshed with the external gear ring 29. The bottom of the base 20 is fixedly installed with an internal gear ring 27 through a plurality of vertical columns 26. The internal gear ring 27 is located below the external gear ring 29. The bottom, annular outer side and annular inner wall of the rotating sleeve 25 are provided with the same discharging groove 35. The annular side of the rotating sleeve 25 is provided with an outer groove 38. The outer groove 38 is located above the discharging groove 35. Rotating holes are provided on the inner walls of the discharging groove 35 and the outer groove 38 close to each other. A rotating cylinder 45 is rotatably installed in the rotating holes. The top center position of the rotating cylinder 45 is fixedly installed with an internal gear 36 through a round shaft 50. An external gear 37 is rotatably installed on the top side inner wall of the outer groove 38. The external gear 37 is meshed with the internal gear 36 and the internal gear ring 27 respectively. The rotation of the external gear ring 29 drives the meshing teeth 30 to rotate. The meshing teeth 30 rotate clockwise. The rotation of the meshing teeth 30 drives the rotating sleeve 25 and the soil guiding plate 28 to rotate clockwise. The rotation of the soil guiding plate 28 guides the soil into the discharging groove 35. At the same time, the rotation of the rotating sleeve 25 drives the external gear 37 to rotate. The external gear 37 rolls on the internal gear ring 27. At this time, the external gear 37 rotates counterclockwise. The rotation of the external gear 37 drives the internal gear 36, the round shaft 50 and the rotating cylinder 45 to rotate. The rotating cylinder 45 and the internal gear 36 rotate clockwise.

[0029] As Figure 11 and Figure 13As shown in the figure, the sealed discharging mechanism further includes a plurality of plate grooves 42 uniformly formed on the annular side of the rotating cylinder 45. Extrusion holes 44 are formed on the top inner walls of the plurality of plate grooves 42. Scraping plates 43 are fixedly installed on the inner walls of the plurality of plate grooves 42 through a reset assembly. The bottom of the scraping plate 43 is at the same horizontal position as the bottom of the rotating sleeve 25. The top of the scraping plate 43 is in contact with the top inner wall of the discharge chute 35. Extrusion rods 46 are fixedly installed on the tops of the plurality of scraping plates 43. The tops of the plurality of extrusion rods 46 respectively penetrate through the plurality of extrusion holes 44 and are rotatably installed with extrusion wheels 41. A baffle 39 is fixedly installed on one inner wall of the outer groove 38. An arc groove is formed on the side of the baffle 39 close to the circular shaft 50. Two of the extrusion wheels 41 are in contact with the inner wall of the arc groove. An extrusion triangular plate 40 is fixedly installed on the side of the baffle 39. The side of the extrusion triangular plate 40 close to the circular shaft 50 corresponds to the position of the extrusion wheel 41. The side of the baffle 39 away from the extrusion triangular plate 40 is in the same plane as the diameter line of the circular shaft 50. When the soil guided by the soil guide plate 28 enters the discharge chute 35, since the rotating cylinder 45 rotates clockwise, the rotation of the rotating cylinder 45 drives the plurality of scraping plates 43 to rotate. The rotation of the plurality of scraping plates 43 drives the plurality of extrusion rods 46 and the extrusion wheels 41 to rotate. When the extrusion wheel 41 contacts the side of the extrusion triangular plate 40, the side of the extrusion triangular plate 40 will squeeze the extrusion wheel 41, causing the extrusion wheel 41 to move. The movement of the extrusion wheel 41 drives the extrusion rod 46 and the scraping plate 43 to move, and the reset assembly deforms until the extrusion wheel 41 reaches the arc groove on the baffle 39. At this time, the position of the extrusion wheel 41 remains unchanged. When the extrusion wheel 41 separates from the arc groove, under the action of the reset assembly, the scraping plate 43 returns to its original state. Thus, when the scraping plate 43 is about to reach the position of the arc block 49, it will contract into the plate groove 42 to avoid interference, and at the same time, it can prevent soil from entering the rotating sleeve 25. When the scraping plate 43 leaves the position of the arc block 49, the scraping plate 43 will return to its original state, so that the soil guided by the soil guide plate 28 can be scraped away.

[0030] As Figure 13 shown, an arc block 49 is fixedly installed on the top inner wall and one inner wall of the discharge chute 35. The arc inner wall of the arc block 49 is in contact with the annular side of the rotating cylinder 45. The arc block 49 and the baffle 39 are located on the same side of the rotating cylinder 45. Through the setting of the arc block 49, dust can be prevented from overflowing from one side of the rotating cylinder 45, and at the same time, soil can be prevented from entering. The soil guide plate 28 and the arc block 49 are located on both sides of the rotating cylinder 45. The inner wall of the discharge chute 35 away from the arc block 49 is arc-shaped. The sides of two of the scraping plates 43 away from the arc block 49 are in contact with the arc inner wall of the discharge chute 35. The advantage of this setting is that at least one side of the scraping plate 43 is in contact with the arc inner wall of the scraping plate 43, so that dust will not overflow in large amounts through the discharge chute 35.

[0031] As Figure 12As shown in the figure, the reset assembly includes two reset rods 48 fixedly installed on the vertical inner wall of the plate groove 42. Two reset grooves are provided on the side of the soil scraping plate 43. The two reset rods 48 respectively extend into the two reset grooves and are fixedly installed with reset springs 47. One ends of the two reset springs 47 away from the reset rods 48 are respectively fixedly installed on the inner walls of the two reset grooves. Through the arrangement of the reset springs 47, after the soil scraping plate 43 moves, the soil scraping plate 43 can be restored to its original state under the action of the reset springs 47.

[0032] As Figure 1 shown in the figure, a plurality of support legs are fixedly installed at the bottom of the base 20, and the bottoms of the plurality of support legs and the bottom of the rotating sleeve 25 are on the same horizontal plane. The advantage of this setting is that the bottom of the rotating sleeve 25 contacts the ground after being placed.

[0033] The working principle and usage process of the present invention: During drilling, the equipment is placed at the position where drilling is required. The second motor 2 is started to rotate the output shaft of the drill rod 6. At the same time, the first motor 1 is started to rotate the rotating shaft 8 and the external thread 3 counterclockwise. The rotation of the external thread 3 causes the moving block 4 to move downward, and then the mounting plate 11, the second motor 2 and the drill rod 6 move downward. After the drill rod 6 passes through the avoidance hole of the base 20, drilling can be carried out; Since the bottom of the rotating sleeve 25 is not in a breathable state, the dust can only be discharged through the avoidance hole. Starting the air extraction pump 22 can generate suction force, so that the dust discharged from the avoidance hole can be inhaled into the annular pipe 18 through a plurality of suction heads 16 and a plurality of mounting pipes 15, and inhaled into the filter box 23 through the connecting hose 19. The dust can be filtered through the filter screen 24. At the same time, the rotation of the rotating shaft 8 drives a plurality of swing rods 7 to rotate. When the swing rod 7 contacts the pressure-receiving rod 9, the swing rod 7 squeezes the pressure-receiving rod 9, so that the pressure-receiving rod 9 rotates. The rotation of the pressure-receiving rod 9 causes the rotating ring 17 and the mounting sleeve 13 to rotate. The rotation of the mounting sleeve 13 causes the mounting spring 12 to deform. When the pressure-receiving rod 9 is separated from the swing rod 7, at this time, under the action of the mounting spring 12, the mounting sleeve 13 and the rotating ring 17 are restored to their original states, so that the rotating ring 17 rotates back and forth, and then a plurality of suction heads 16 rotate back and forth to adsorb the dust back and forth; Meanwhile, the soil drilled out by the drill pipe 6 is located inside the rotating sleeve 25. The rotating shaft 8 rotates counterclockwise, causing the moving wheel 33 to rotate. The moving wheel 33 squeezes the vertical side of the right-angled triangular block 31, causing the external gear ring 29 to rotate. The rotation of the external gear ring 29 drives the meshing gear 30 to rotate. The meshing gear 30 rotates clockwise. The rotation of the meshing gear 30 drives the rotating sleeve 25 and the soil guiding plate 28 to rotate clockwise. The rotation of the soil guiding plate 28 guides the soil into the discharge chute 35. At the same time, the rotation of the rotating sleeve 25 drives the external gear 37 to rotate. The external gear 37 rolls on the internal gear ring 27. At this time, the external gear 37 rotates counterclockwise. The rotation of the external gear 37 drives the internal gear 36, the circular shaft 50, and the rotating cylinder 45 to rotate. The rotating cylinder 45 and the internal gear 36 rotate clockwise; When the soil guided by the soil guiding plate 28 enters the discharge chute 35, due to the clockwise rotation of the rotating cylinder 45, the rotation of the rotating cylinder 45 drives the rotation of multiple soil scraping plates 43. The rotation of multiple soil scraping plates 43 drives the rotation of multiple extrusion rods 46 and extrusion wheels 41. When the extrusion wheel 41 contacts the side of the extrusion triangular plate 40, the side of the extrusion triangular plate 40 will squeeze the extrusion wheel 41, causing the extrusion wheel 41 to move. The movement of the extrusion wheel 41 drives the extrusion rod 46 and the soil scraping plate 43 to move. The movement of the soil scraping plate 43 causes the two reset rods 48 to enter the two reset slots, and the two reset springs 47 deform until the extrusion wheel 41 reaches the arc-shaped groove on the baffle 39. At this time, the position of the extrusion wheel 41 remains unchanged. When the extrusion wheel 41 separates from the arc-shaped groove, under the reaction force of the two reset springs 47, the soil scraping plate 43 returns to its original state, thus realizing that when the soil scraping plate 43 is about to reach the position of the arc-shaped block 49, it will shrink into the plate groove 42 to avoid entering, and at the same time, prevent soil from entering the rotating sleeve 25. When the soil scraping plate 43 leaves the position of the arc-shaped block 49, the soil scraping plate 43 will return to its original state, so that the soil guided by the soil guiding plate 28 can be scraped away. At the same time, the side of at least one soil scraping plate 43 contacts the arc-shaped inner wall of the soil scraping plate 43, so that dust will not overflow a large amount through the discharge chute 35; After the drilling is completed, at this time, the first motor 1 is started to make the rotating shaft 8 and the external thread 3 rotate clockwise, which can make the second motor 2 and the drill pipe 6 return to their original states. At the same time, the clockwise rotation of the rotating shaft 8 causes the inclined side of the right-angled triangular block 31 to contact the moving wheel 33. However, when the extrusion wheel 41 on the rotating cylinder 45 rotates counterclockwise and contacts the side of the baffle 39, it will get stuck, causing the meshing gear 30 and the external gear ring 29 to be unable to rotate. As a result, the moving wheel 33 is squeezed by the inclined side of the right-angled triangular block 31 to make way, and the moving spring 32 deforms. After the avoidance is completed, under the action of the moving spring 32, the moving wheel 33 returns to its original state.
