Description

Technical Field

[0001] The invention relates to the technical field of belt rollers, and in particular to a self-driven cargo bag cleaning roller structure and a use method thereof. Background Art

[0002] Coal mines often use belt rollers to provide power for conveying coal powder. Such belt rollers include: a base, a roller and a motor. The roller is mounted on the base, and the motor is rotatably connected to the roller. The problem with such belt rollers is that after the belts have been used for a long time, especially when the coal powder is wet, it is particularly easy for the coal powder to stick to the belts. Coal powder sticking to the belts will cause the following problems:

[0003] 1) The coal powder transported by the belt adheres to the belt, causing the total amount of coal powder to be lost;

[0004] 2) The returned coal powder under the belt often enters the conveyor system, thereby damaging the drum and rollers, and causing belt deflection and wear;

[0005] 3) When the coal powder sticks to the belt outside the front pulley, the additional weight of the coal powder sticking to the belt makes the equipment work more difficult, so it will use more energy;

[0006] 4) Fugitive dust is usually a byproduct of coal dust that falls under the belt during the return journey, causing the coal dust to float in the work space.

[0007] In order to solve the above problems, the applicant has developed a belt roller with a bag cleaning function, comprising: a base; a roller, which is installed on the base; a motor, which is rotatably connected to the roller; a scraper, the scraping edge of the scraper is parallel to the central axis of the roller, and the distance between the scraping edge of the scraper and the surface of the roller is greater than the thickness of the belt; a cylinder, which is detachably mounted on the base, the side surface of the cylinder is connected to the lower opening of the collecting trough, and a discharge port is provided at the lower part of the side surface of the cylinder; an auger, which matches the inner diameter of the cylinder, the auger is rotatably installed in the cylinder, and the projection of the auger on the horizontal plane completely covers the projection of the collecting trough on the horizontal plane; a driving device, which is rotatably connected to the auger.

[0008] However, the applicant found in actual use that an additional set of driving devices is required to drive the auger to rotate. The addition of this set of driving devices requires either a motor or an internal combustion engine. Adding an internal combustion engine and a motor will increase the manufacturing cost of the equipment. In addition, the internal combustion engine and the motor have complex structures, are easily damaged, and have low reliability. Summary of the invention

[0019] The driving wheel is fixedly connected to the rotating shaft of the drum, the central axis of the driving wheel coincides with the central axis of the drum, and the outer surfaces of the driving wheel and the driven wheel are tangent and contact with each other.

[0020] Furthermore, a layer of anti-slip rubber is fixedly connected to the outer surface of the driven wheel.

[0021] Furthermore, the clockwise angle between the upper surface of the scraper and the moving direction of the belt is greater than 90 degrees and less than 180 degrees, and the thickness of the scraper gradually decreases from the side away from the scraping edge to the side of the scraping edge.

[0022] Furthermore, fixed arms are provided on the left and right sides of the base, and the mounting arms are fixedly connected on the left and right sides of the lower bottom surface of the cylinder. The distance between the mounting arms on the left and right sides is the same as the distance between the fixed arms on the left and right sides, and the width of the mounting arms on the left and right sides is the same as the width of the fixed arms on the left and right sides. The cylinder is detachably connected to the fixed arms and the mounting arms through a clamping device.

[0023] Furthermore, a first rack is provided on the upper surface of the fixed arm along the length direction of the fixed arm, and a second rack is provided on the lower surface of the mounting arm along the length direction of the mounting arm.

[0027] Furthermore, the clamping device further comprises:

[0028] A pressing plate is fixedly connected to the lower end of the fastening screw, the pressing plate is circular, the diameter of the pressing plate is smaller than the hole width of the frame, and a layer of rubber is fixedly connected to the lower surface of the pressing plate.

[0034] S03. Adjust the rotary rod to tighten the pressure plate from the upper part of the mounting arm to fix the roller on the base.

[0035] The beneficial effects of the present invention are: compared with the prior art,

[0036] 1) The scraper of the present invention contacts the belt and scrapes the coal powder off with the movement of the belt, thereby automatically cleaning the coal powder adhered to the belt. The coal powder scraped off the belt falls into the collecting tank and falls into the cylinder through the lower opening of the collecting tank. Since the driven wheel contacts the driving wheel, the driving wheel rotates under the drive of the belt, thereby causing the driven wheel to rotate. The auger in the cylinder is driven by the driven wheel to rotate, so that the coal powder falling into the cylinder is pushed by the auger to be transported to the discharge port for centralized collection. Compared with the traditional auger, an additional driving device is required to drive the auger to rotate. The present invention uses the power of the rotation of the drum itself to drive the auger to rotate, eliminating the driving device for driving the auger, saving more costs, and only providing power to the auger through the cooperation of the driving wheel and the driven wheel. Compared with the complex structure of the motor and the internal combustion engine, the present invention has a simpler structure and higher reliability.

[0037] 2) The present invention increases the friction between the driving wheel and the driven wheel by fixing a layer of anti-skid rubber on the outer surface of the driven wheel, thereby preventing the driving wheel and the driven wheel from slipping;

[0038] 3) The present invention makes the clockwise angle between the upper surface of the scraper and the moving direction of the belt greater than 90 degrees and less than 180 degrees, so that the scraping edge of the scraper can be inserted into the coal powder layer adhered to the belt, and the coal powder is scraped off as the belt moves, thereby automatically cleaning the coal powder adhered to the belt. The thickness of the scraper gradually decreases from the side away from the scraping edge to the side of the scraping edge, so that the scraping edge of the scraper is sharper and easier to insert into the coal powder layer adhered to the belt, and the resistance to the belt in cleaning the coal powder adhered is smaller;

[0039] 4) The present invention detachably connects the cylinder to the base through a clamping device, so that the scraper can be moved by moving the cylinder, thereby adjusting the relative position of the scraper and the belt;

[0040] 5) The present invention cooperates with the frame and the fastening screw. When the fastening screw is tightened, the relative position between the fixed arm and the mounting arm is locked. When the fastening screw is loosened, the relative position between the fixed arm and the mounting arm can be adjusted, thereby achieving the adjustment of the relative position between the scraper and the belt;

[0041] 6) The present invention achieves the fixation of the relative position between the fixed arm and the mounting arm by cooperating with the first rack and the second rack, thereby preventing the relative position between the scraper and the belt from changing when the machine is running;

[0042] 7) The present invention contacts the mounting arm through the pressing plate, and a layer of rubber is fixedly connected to the lower part of the pressing plate, so that the friction between the pressing plate and the mounting arm is increased, thereby preventing the relative position between the mounting arm and the fixed arm from changing due to vibration during operation of the device;

[0043] 8) The present invention applies force to rotate the fastening screw by means of a rotating rod, and since the rotating rod has a larger diameter, it is easier to rotate the fastening screw;

[0044] 9) The present invention adjusts the distance d between the lower surface of the scraper and the side of the drum by adjusting the tightness of the pressure plate by adjusting the rotary rod, so that d is greater than the belt thickness and less than d+1mm, so that the scraper can clean the coal powder adhering to the belt without scratching the belt. At the same time, the outer surfaces of the driving wheel and the driven wheel are tangent and contact with each other. The drum rotates under the drive of the belt, driving the auger to rotate at the same time, so that the adhering coal powder cleaned from the belt can be transported to the discharge port by the auger for centralized treatment.

[0064] S03, adjusting the rotary rod 905 to make the pressing plate 903 press from the upper part of the mounting arm 8, so that the drum 2 is fixed on the base 1.

[0065] The beneficial effects of the present invention are: compared with the prior art,

[0066] 1) The scraper 4 of the present invention contacts the belt and scrapes the coal powder off with the movement of the belt, thereby automatically cleaning the coal powder adhered to the belt. The coal powder scraped off the belt falls into the collecting tank 5 and falls into the cylinder 701 through the lower opening of the collecting tank 5. Since the driven wheel 3 contacts the driving wheel 10, the driving wheel 10 rotates under the drive of the belt, thereby causing the driven wheel 3 to rotate. The auger 702 in the cylinder 701 is driven by the driven wheel 3 to rotate, so that the coal powder falling into the cylinder 701 is pushed by the auger 702 and transported to the discharge port 703 for centralized collection. Compared with the traditional auger 702, an additional driving device is required to drive the auger 702 to rotate. The present invention uses the power of the rotation of the drum 2 itself to drive the auger 702 to rotate, eliminating the driving device for driving the auger 702, saving more costs, and only providing power to the auger 702 through the cooperation of the driving wheel 10 and the driven wheel 3. Compared with the complex structure of the motor and the internal combustion engine, the structure of the present invention is simpler and more reliable.

[0067] 2) The present invention increases the friction between the driving wheel 10 and the driven wheel 3 by fixing a layer of anti-skid rubber 301 on the outer surface of the driven wheel 3, thereby preventing the driving wheel 10 and the driven wheel 3 from slipping;

[0068] 3) The present invention makes the clockwise angle between the upper surface of the scraper 4 and the moving direction of the belt greater than 90 degrees and less than 180 degrees, so that the scraping edge 401 of the scraper 4 can be inserted into the coal powder layer adhered to the belt, and the coal powder is scraped off as the belt moves, thereby automatically cleaning the coal powder adhered to the belt. The thickness of the scraper 4 gradually decreases from the side away from the scraping edge 401 to the side of the scraping edge 401, so that the scraping edge 401 of the scraper 4 is sharper and easier to insert into the coal powder layer adhered to the belt, and the resistance to the belt when cleaning the coal powder adhered is smaller;

[0069] 4) The present invention connects the cylinder 701 to the base 1 detachably through the clamping device 9, so that the scraper 4 can be moved by moving the cylinder 701, thereby adjusting the relative position of the scraper 4 and the belt;

[0070] 5) The present invention cooperates with the frame 901 and the fastening screw 904. When the fastening screw 904 is tightened, the relative position between the fixed arm 101 and the mounting arm 8 is locked. When the fastening screw 904 is loosened, the relative position between the fixed arm 101 and the mounting arm 8 is adjustable, thereby achieving the adjustment of the relative position between the scraper 4 and the belt;

[0071] 6) The present invention achieves the fixation of the relative position between the fixed arm 101 and the mounting arm 8 by cooperating with the first rack 1011 and the second rack 801, thereby preventing the relative position between the scraper 4 and the belt from changing when the machine is running;

[0072] 7) The present invention contacts the mounting arm 8 through the pressing plate 903, and a layer of rubber is fixedly connected to the lower part of the pressing plate 903, so that the friction between the pressing plate 903 and the mounting arm 8 is increased, thereby preventing the relative position between the mounting arm 8 and the fixed arm 101 from changing due to vibration during operation of the device;

[0073] 8) The present invention applies force to rotate the fastening screw 904 through the rotating rod 905. Since the rotating rod 905 has a larger diameter, it is easier to rotate the fastening screw 904.

[0074] 9) The present invention adjusts the tightness of the pressure plate 903 by adjusting the rotary rod 905, thereby adjusting the distance d between the lower surface of the scraper 4 and the side of the drum 2, so that d is greater than the belt thickness and less than d+1mm, so that the scraper 4 can clean the coal powder adhering to the belt without scratching the belt. At the same time, the driving wheel 10 is tangent to the outer surface of the driven wheel 3 and contacts each other. The drum 2 rotates under the drive of the belt, driving the auger 702 to rotate at the same time, so that the adhering coal powder cleaned from the belt can be simultaneously transported by the auger 702 to the discharge port 703 for centralized processing.

[0075] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
