Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, and more specifically, to a device for automatically adjusting the surface area of ​​a cleaning belt. Background Art

[0002] When the minerals are transported by belt in the concentrator, affected by factors such as material moisture, external natural conditions, and material particle size, after the belt is transported to the machine head for unloading, more or less material will stick to the surface. When it runs to the second floor and returns through the lower roller, it will be scraped off by the lower roller, causing material accumulation. If the material viscosity is high, a lot of material will fall off and accumulate on the belt in a short time, which will not only affect production, but also cause the lower roller to be buried in the material, affecting the service life of the roller.

[0003] In order to clean the belt, corresponding cleaning equipment is needed. Traditional belt head cleaning usually uses a heavy hammer or manually adjusted cleaning equipment to clean the belt after unloading. However, when adjusting the rubber of the cleaning equipment, the traditional cleaning equipment is fixed as a whole, so the cleaning equipment needs to be dismantled for adjustment, which takes a long time, requires a lot of manpower, and is inconvenient to operate. The counterweight type cleaner has an unstable counterweight. When the hardness of the material adhered to the surface of the belt is high, the friction of the material when passing through the cleaner is greater than the counterweight, which will cause the counterweight to float up and down. Both cannot achieve the effect of cleaning and cannot meet the current environmental protection standards. Therefore, it needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figures 1 to 5 As shown, the utility model provides a device for automatically adjusting the surface area of ​​a cleaning belt, comprising:

[0029] A bracket 1, wherein a U-shaped bracket 2 is movably sleeved in the middle of the outer surface of the bracket 1;

[0030] A cleaning mechanism 3, which is arranged inside the U-shaped frame 2;

[0031] A driving mechanism 4, which is arranged at the top of the U-shaped frame 2;

[0032] Among them, the cleaning mechanism 3 includes a limiting column 301, and the number of the limiting columns 301 is two. The two limiting columns 301 are respectively movably installed at the bottom inside the left and right ends of the U-shaped frame 2, and the top ends of the two limiting columns 301 are respectively movably sleeved with extension columns 302, and the top ends of the extension columns 302 are fixedly installed with mounting rods 303, and the bottom ends of the mounting rods 303 are fixedly installed with cleaning rubber plates 304. The bottom ends of the two limiting columns 301 are respectively fixedly installed with springs 305, and the other ends of the springs 305 are fixedly connected to the bottom ends of the mounting rods 303. The bottom ends of the two limiting columns 301 are respectively fixedly installed with vertical rods 306 located inside the springs 305, and the top ends of the vertical rods 306 pass through the mounting rods 303 and the U-shaped frame 2 and extend to the outside of the U-shaped frame 2 and are fixedly sleeved with cross rods 307. The springs 305 will move the cleaning rubber plates 304 downward.

[0033] Since the spring 305 is in a stretched state, the spring 305 will generate a downward pulling force on the mounting rod 303 under the restoring action of the spring 305, pulling the mounting rod 303 and moving the cleaning rubber plate 304 downward along the outer surface of the vertical rod 306, and the limiting column 301 and the extension column 302 can protect the spring 305 to prevent debris from entering the interior of the spring 305 and causing the spring 305 to get stuck. Under the action of the spring 305, the cleaning rubber plate 304 and the conveyor belt can always be kept in contact with each other according to the tightness of the conveyor belt, thereby achieving the purpose of cleaning, saving time and effort.

[0034] Wherein, the driving mechanism 4 includes:

[0035] A driving motor 401 is fixedly mounted on the top of the right end of the U-shaped frame 2, and a threaded rod 402 is fixedly sleeved on the other end of the output shaft of the driving motor 401;

[0036] The movable block 403 is threadedly sleeved on the right side of the outer surface of the threaded rod 402.

The other end of the connecting rod 404 is hinged to the middle part of the rear end of the cross bar 307.

[0037] When the driving motor 401 is started, the threaded rod 402 will rotate, so that the movable block 403 will move to the left with the connecting rod 404, and then the other end of the connecting rod 404 will generate a thrust on the cross bar 307, pushing the cross bar 307 to move upward with the limit column 301 through the vertical rod 306, so that the cleaning device can adjust the elastic force of the spring 305 according to the degree of wear of the cleaning rubber plate 304, and then the cleaning device can stick to the surface of the transmission equipment belt with a fixed force, so as to achieve the effect of cleaning the surface of the transmission equipment belt.

[0038] Among them, a first motor 5 is fixedly installed on the left side of the bottom end of the bracket 1, and the other end of the output shaft of the first motor 5 is fixedly sleeved with a first rotating shaft 6. The top end of the first rotating shaft 6 passes through the bracket 1 and extends to the top of the outer surface of the bracket 1. An active roller 7 is fixedly sleeved on the outer surface of the first rotating shaft 6, and the active roller 7 is movably sleeved on the left end inside the bracket 1.

[0039] When the first motor 5 is started, the first rotating shaft 6 will drive the active roller 7 to rotate.

[0040] Among them, the right end of the inside of the bracket 1 is fixedly sleeved with a fixed shaft 8, and the outer surface of the fixed shaft 8 is movably sleeved with a driven roller 9. The outer surface of the driven roller 9 is movably sleeved with the inner surface of the bracket 1. The driven roller 9 is connected to the active roller 7 through a transmission belt 10, and the outer surface of the transmission belt 10 is movably connected to the outer surface of the cleaning rubber plate 304.

[0041] When the active roller 7 rotates, the transmission belt 10 will rotate because the active roller 7 is connected to the driven roller 9 through the transmission belt 10.

[0042] Among them, a support plate 11 is fixedly installed at the bottom of the left end of the U-shaped frame 2, a second motor 12 is fixedly installed at the left end of the support plate 11, and a second rotating shaft 13 is fixedly sleeved on the other end of the output shaft of the second motor 12. The right end of the second rotating shaft 13 passes through the support plate 11 and extends to the outside of the support plate 11.

[0043] When the second motor 12 is started, the second rotating shaft 13 will rotate.

[0044] Among them, a disc 14 is fixedly sleeved on the front side of the outer surface of the second rotating shaft 13, and connecting rods 15 are hinged on the upper left and lower right of the front end of the disc 14. There are two connecting rods 15 and they are symmetrical with each other about the center of the disc 14. The disc 14 will drive the connecting rods 15 to rotate.

[0045] When the second rotating shaft 13 drives the disk 14 to rotate, one end of the two connecting rods 15 will rotate together.

[0046] Among them, the other ends of the two connecting rods 15 are respectively hinged with a pressure block 16, and the number of the pressure blocks 16 is two. The two pressure blocks 16 are respectively movably sleeved on the bottom of the left and right ends of the U-shaped frame 2, and the tops of the two pressure blocks 16 on the back sides are respectively movably connected to the left and right inner walls of the bracket 1, and the back sides of the two pressure blocks 16 are respectively fixedly installed with baffles 17 located on the outside of the U-shaped frame 2.

[0047] When one end of the connecting rod 15 rotates, the other end of the connecting rod 15 generates a pulling force on the pressing block 16, pulling the two pressing blocks 16 and the two baffles 17 to move toward each other.

[0048] The working principle and use process of this utility model:

[0049] Firstly, when using the cleaning device, start the second motor 12 so that the second rotating shaft 13 drives the disc 14 to rotate. At this time, one end of the two connecting rods 15 hinged to the disc 14 will rotate together, so that the other ends of the two connecting rods 15 respectively generate a thrust on the two pressure blocks 16, pushing the two pressure blocks 16 to move away from each other with the two baffles 17, until the pressure blocks 16 and the U-shaped frame 2 are tightly fitted, thereby fixing the cleaning device to prevent the cleaning device from shaking during use. With the mutual cooperation of various mechanisms, the fixing of the cleaning device is more convenient.

[0050] Then, the operator starts the driving motor 401 according to the degree of wear of the cleaning rubber plate 304, so that the threaded rod 402 rotates, so that the movable block 403 threadedly sleeved with the threaded rod 402 moves along the top of the U-shaped frame 2 with the bottom end of the connecting rod 404, and then the top of the connecting rod 404 generates a thrust on the cross bar 307, pushing the cross bar 307 to move with the limit column 301 through the vertical rod 306, thereby achieving the purpose of adjusting the elastic force of the spring 305 according to the degree of wear of the cleaning rubber plate 304. Then, the operator starts the first motor 5, so that the first rotating shaft 6 rotates with the active roller 7. Since the active roller 7 and the driven roller 9 are connected through the transmission belt 10, the transmission belt 10 will rotate. Since the spring 305 is in a stretched state at this time, the installation rod 303 will move downward along the inner surface of the limit column 301 with the cleaning rubber plate 304 and the extension column 302 under the recovery effect of the spring 305, thereby ensuring that the spring 305 and the outer surface of the transmission belt 10 are in contact with each other with a fixed force, and then as the transmission belt 10 rotates, the surface of the transmission belt 10 is cleaned.
