Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of pulverized coal cleaning, and particularly to a shaftless collecting robot for roadway pulverized coal. Background Art
[0002] In the field of coal mining technology, in impact ground pressure mines, pre-drainage boreholes need to be constructed at the sidewalls and headings of driving roadways, and at the sidewalls of the two crossheadings of the mining face. Due to the large number of boreholes constructed, a large amount of pulverized coal will be generated. Since the roadway environment where the pulverized coal exists is relatively complex, large-scale cleaning equipment or rigid cleaning equipment is difficult to use in narrow and tortuous environments (such as under mechanical equipment like belt conveyors). Therefore, the traditional cleaning method is manual cleaning, that is, workers use simple cleaning tools such as shovels to clean the pulverized coal onto the belt or mine car and then transfer it out. This results in a large labor intensity, a long cleaning time, and at the same time, the pulverized coal in the roadway will float, affecting the health of workers and even causing accidents such as explosions, highlighting the deficiencies of the prior art. Summary of the Invention
[0003] The purpose of the present invention is to provide a shaftless collecting robot for roadway pulverized coal to solve the above technical problems.
[0004] To achieve the above purpose, the present invention adopts the following technical solutions:
[0005] A shaftless collecting robot for roadway pulverized coal includes a base, a pneumatic motor, a controller, a discharge cylinder, a discharge port, a conveying cylinder, a bracket, a suction port, a main support seat, a front support disk, a rear support disk, a screw blade, rollers, and a magnetic attraction part. A horizontal pneumatic motor is fixed on the upper part of the base, and a controller is installed at the top end. A horizontal discharge cylinder is fixed at the front part of the base. The discharge cylinder is provided with a discharge port. A flexible conveying cylinder is fixed at the front end of the discharge cylinder. The front end of the conveying cylinder is fixed with a bracket. The bracket is provided with a plurality of suction ports, and a horizontal main support seat is fixed at the front end. The rear part of the main support seat is rotatably connected with a front support disk. The front end of the output shaft of the pneumatic motor is coaxially fixed with a rear support disk. The front support disk and the rear support disk jointly fix a flexible and shaftless screw blade. Two rollers are rotatably arranged at the upper, lower, left, and right ends of the main support seat. The main support seat is also provided with a magnetic attraction part.
[0006] Based on the above technical solution, the magnetic attraction part includes a servo motor, a transmission column, a rack, a support shell, a first permanent magnet, a secondary support seat, a second bidirectional screw, a third bidirectional screw, a gear, a second permanent magnet, and a third permanent magnet. A horizontal servo motor is fixed to the rear of the main support seat. The rotating shaft of the servo motor is coaxially threadedly connected to the transmission column. Horizontal racks are fixed to the top and right end of the transmission column, and a support shell is fixed to the front. The first permanent magnet is fixed inside the support shell and is slidably connected to the main support seat in the front-back direction. A secondary support seat is fixed to the rear of the main support seat. The secondary support seat rotatably connects a horizontal second bidirectional screw and a vertical third bidirectional screw. Gears are coaxially fixed to the second bidirectional screw and the third bidirectional screw respectively. The two gears mesh with the two racks. Horizontal second permanent magnets are threadedly connected to the left and right parts of the second bidirectional screw respectively. Vertical third permanent magnets are threadedly connected to the upper and lower parts of the third bidirectional screw respectively. The two second permanent magnets are slidably connected to the main support seat in the left-right direction. The two third permanent magnets are slidably connected to the main support seat in the up-down direction.
[0007] Based on the above technical solution, the pneumatic motor is externally connected to a gas source. The controller is electrically connected to the servo motor. The controller is externally connected to a power source. The inner cavity of the discharge cylinder is communicated with the inner cavity of the conveying cylinder. The auger blade is inserted into the conveying cylinder with a gap. When the servo motor is energized to rotate forward and backward, it can drive the transmission column to move back and forth. When the transmission column moves back and forth, the second bidirectional screw and the third bidirectional screw can be driven to rotate forward and backward through the racks and gears. When the second bidirectional screw rotates forward and backward, it can make the second permanent magnets slide left and right. When the third bidirectional screw rotates forward and backward, it can make the third permanent magnets slide up and down.
[0008] Compared with the prior art, the present invention has the following advantages: By controlling the pneumatic motor to drive the auger blade to rotate, and then cooperating with the flexible conveying cylinder, the main support seat can conveniently enter a narrow and tortuous space to quickly collect and clean the pulverized coal, improving the collection efficiency. Since the auger blade is intermittently inserted into the conveying cylinder, the pulverized coal can be prevented from floating during the conveying process. By controlling the servo motor to rotate forward and backward in a timely manner, the first permanent magnet, the second permanent magnet, and the third permanent magnet can be expanded or contracted, so that the first permanent magnet, the second permanent magnet, and the third permanent magnet can magnetically adsorb with materials that can be magnetically adsorbed in the outside world, or the rollers can be brought into contact with the outside world, so that the position of the suction port can be conveniently changed, or the position of the suction port can be kept stable, thus facilitating the collection and cleaning of the pulverized coal and greatly reducing the labor intensity.

[0015] As Figures 1 - 4 shown, a shaftless roadway coal powder collection robot includes a base 1, a pneumatic motor 2, a controller 3, a discharge cylinder 4, a discharge port 5, a conveyor cylinder 6, a bracket 7, a suction port 8, a main support seat 9, a front support disc 10, a rear support disc 11, an auger blade 12, a roller 13, and a magnetic attraction part 14. A horizontal pneumatic motor 2 is fixed on the upper part of the base 1, and a controller 3 is installed at the top. A horizontal discharge cylinder 4 is fixed at the front of the base 1. The discharge cylinder 4 is provided with a discharge port 5. A flexible conveyor cylinder 6 is fixed at the front end of the discharge cylinder 4. The front end of the conveyor cylinder 6 is fixed with a bracket 7. The bracket 7 is provided with a plurality of suction ports 8, and a horizontal main support seat 9 is fixed at the front end. The rear part of the main support seat 9 is rotatably connected to a front support disc 10. The front end of the output shaft of the pneumatic motor 2 is coaxially fixed with a rear support disc 11. The front support disc 10 and the rear support disc 11 jointly fix a flexible and shaftless auger blade 12. The flexible and shaftless feature of the auger blade 12 can follow the flexible conveyor cylinder 6 to bend to a certain extent, so as to adapt to a narrow and tortuous space environment. Two rollers 13 are rotatably arranged at the upper and lower ends and the left and right ends of the main support seat 9 respectively. By contacting the outside through the rollers 13, the main support seat 9 can be conveniently moved. The main support seat 9 is also provided with a magnetic attraction part 14.
[0016] The magnetic attraction part 14 includes a servo motor 15, a transmission column 16, a rack 17, a support shell 18, a first permanent magnet 19, a secondary support seat 20, a second bidirectional screw 21, a third bidirectional screw 22, a gear 23, a second permanent magnet 24, and a third permanent magnet 25. A horizontal servo motor 15 is fixed to the rear of the main support seat 9. The rotating shaft of the servo motor 15 is coaxially and threadedly connected to a transmission column 16. A horizontal rack 17 is fixed to the top and the right end of the transmission column 16, and a support shell 18 is fixed to the front. A first permanent magnet 19 is fixed inside the support shell 18 and is slidably connected to the main support seat 9 in the front and rear directions. A secondary support seat 20 is fixed to the rear of the main support seat 9. The secondary support seat 20 is rotatably connected to a horizontal second bidirectional screw 21 and a vertical third bidirectional screw 22. The second bidirectional screw 21 and the third bidirectional screw 22 are coaxially fixed with gears 23 respectively. The two gears 23 are engaged with the two racks 17. A horizontal second permanent magnet 24 is threadedly connected to each of the left and right parts of the second bidirectional screw 21. A vertical third permanent magnet 25 is threadedly connected to each of the upper and lower parts of the third bidirectional screw 22. The two second permanent magnets 24 are slidably connected to the main support seat 9 in the left and right directions. The two third permanent magnets 25 are slidably connected to the main support seat 9 in the up and down directions.
[0017] The pneumatic motor 2 is connected to an external air source. The controller 3 is electrically connected to the servo motor 15. The controller 3 is connected to an external power source. The inner cavity of the discharge cylinder 4 is communicated with the inner cavity of the conveying cylinder 6. The auger blade 12 is inserted into the conveying cylinder 6 with a gap. When the servo motor 15 is energized to rotate forward and backward, it can drive the transmission column 16 to move back and forth. When the transmission column 16 moves back and forth, the second bidirectional screw 21 and the third bidirectional screw 22 can be rotated forward and backward through the racks 17 and the gears 23. When the second bidirectional screw 21 rotates forward and backward, it can make the second permanent magnets 24 slide left and right. When the third bidirectional screw 22 rotates forward and backward, it can make the third permanent magnets 25 slide up and down.
[0018] Working principle of the present invention: When in use, an external air source is used to make the pneumatic motor 2 rotate, thereby driving the rear support disk 11, the auger blade 12 and the front support disk 10 to rotate by means of the pneumatic motor 2. The auger blade 12 rotates in the conveying cylinder 6 to suck pulverized coal into the conveying cylinder 6 through the suction port 8, and then uses the auger blade 12 for screw conveyance and finally discharges it from the discharge port 5. By controlling the servo motor 15 to rotate in the reverse direction, the transmission column 16, the support shell 18 and the first permanent magnet 19 can be moved backward, and the engagement of the rack 17 and the gear 23 can be used to make the second bidirectional screw 21 and the third bidirectional screw 22 rotate in the reverse direction, so that the two second permanent magnets 24 can approach each other, and the two third permanent magnets 25 can approach each other, that is, the support shell 18, the second permanent magnet 24 and the third permanent magnet 25 can contract into the main support seat 9, so that the rollers 13 can contact the external support, facilitating the movement of the main support seat 9 and changing the relative position of the suction port 8 to the outside, so as to facilitate the collection and cleaning of pulverized coal at different positions. By controlling the servo motor 15 to rotate in the forward direction, the support shell 18, the second permanent magnet 24 and the third permanent magnet 25 can be expanded out of the main support seat 9, so that the first permanent magnet 19, the second permanent magnet 24 and the third permanent magnet 25 can be magnetically adsorbed to the external magnetically adsorbable materials (most of the various mining equipment in the roadway is made of iron and can be magnetically adsorbed), so as to ensure the stability of the relative position of the suction port 8 to the outside, and then ensure the stable and continuous collection and cleaning of pulverized coal at a certain position.
[0019] The above is a preferred embodiment of the present invention. For those of ordinary skill in the art, according to the teachings of the present invention, without departing from the principle and spirit of the present invention, the changes, modifications, substitutions and variations made to the implementation manners still fall within the protection scope of the present invention.
