Belt conveyors are used to convey loose materials or pieces of goods such as coal, crushed stone, sand, cement, fertilizer, grain, and the like. After a long-term operation of the belt conveyor, a part of materials can be adhered to the working surface of the conveyor belt. When the material is unloaded, the adhered part of the material can not be unloaded, and the running resistance of the belt conveyor can be increased; and the material can also stick on the roller surface, and with the increase of stickers, the stickers can bypass the machine head roller and stick on the return idler, so that the conveying belt deviates, and the abrasion of the conveying belt and the supporting part is increased.
The sweeper is one of the main parts on the belt conveyor, and the main function of the sweeper is to remove materials adhered to the surface of the conveyor belt after the conveyor belt is unloaded through a scraper part on the sweeper, so that the service life of the conveyor belt is prolonged. The scraper of ordinary sweeper is integral, and a plurality of scrapers set up on same part, because the material size of conveyer belt different position adhesion in the operation is different, and the material of adhesion is inhomogeneous, can lead to the scraper wearing and tearing volume of different positions different. Therefore, the scraper can be set to be split, and a compensation mechanism is arranged at the installation part of each scraper, so that the influence of different abrasion loss of the scrapers at different positions on the scraping effect of the scrapers is avoided.

The scrapers at different positions are respectively compensated through the spring compensation adjusting mechanism, so that the effective control of the scrapers at different positions on the laminating distance of the conveying belt is realized, and the overall cleaning effect is ensured. However, the spring compensation adjusting mechanism is in direct contact with the connecting plate 3 during operation, the spring 1 and the connecting plate 3 can slide relatively along with the rotation of the scraper during adjustment, the spring 1 and the connecting plate 3 have friction resistance due to the elasticity of the spring 1, and the spring 1 and the connecting plate can slide relatively along with the rotation of the scraper during long-time operation, so that the adjusting effect of the spring compensation adjusting mechanism is finally affected, the adjustment is insensitive, and the compensation adjustment can not be realized even, so that the split type scraper fails, and the operation requirement of the sweeper can not be met.

When the adjusting plate 5 rotates along with the scraper seat 4, the first fixing plate 7 and the adjusting pulley 6 will displace, and the adjusting pulley 6 will rotate relative to the first fixing plate 7. The resistance is reduced when the displacement occurs, and the adjustment sensitivity of the integral compensation mechanism is improved.
Example three:
as shown in fig. 6, the difference between the present embodiment and the first embodiment is: the adjusting plate 5 is a bending plate. The bending plate is a plate with a bending angle, and when the bending plate is installed, the bending part faces one side of the adjusting pulley 6, so that the sliding resistance between the adjusting pulley 6 and the adjusting plate 5 can be reduced during compensation.
Example four:
as shown in fig. 7, the difference between the present embodiment and the first embodiment is: the adjusting plate 5 is a flat plate, and installation and maintenance can be facilitated by arranging the flat plate, and inspection and maintenance of the adjusting spring 8 are facilitated.
Example five:
as shown in fig. 8 and 9, the difference between the first embodiment and the second embodiment is: the adjusting seat 11 is fixedly arranged on the cross beam 13, and two ends of the cross beam 13 are provided with tensioning mechanisms for limiting the rotation of the cross beam 13.
The adjusting seat 11 is welded with the cross beam 13 or fixedly connected with the cross beam 13 through bolts, the cross beam 13 is a circular beam, the two sides of the cross beam 13 can be tensioned in a rotating mode through the tensioning mechanism, the tensioning mechanism can adjust the distance between the scraper and the material of the conveying belt, and secondary compensation of the scraper is achieved.
As shown in fig. 8, the tensioning mechanism includes a tensioning seat 16, a tensioning plate 17, a tensioning spring 18, a tensioning shaft 19 and a tensioning nut 20, wherein one end of the tensioning plate 17 is fixedly connected with the cross beam 13 and can rotate along the cross beam 13, the tensioning shaft 19 is arranged through the tensioning plate 17, one end of the tensioning shaft 19 is connected with the tensioning seat 16, and the tensioning spring 18 is arranged on the tensioning shaft 19 and is locked by the tensioning nut 20.
The tensioning seat 16 is fixedly connected with the whole equipment base, so that the tensioning seat 16 is fixed. The cross beam 13 is rotatable along the tensioning seat 16, and the tensioning plate 17 is fixedly connected to the cross beam 13 by means of bolts or welding. The tensioning shaft 19 is connected with the tensioning seat 16, a sleeve 23 is welded at one end of the tensioning shaft 19, a rotating shaft 24 is welded on the tensioning seat 16, and the sleeve 23 is sleeved on the rotating shaft 24, so that the tensioning shaft 19 can rotate along the rotating shaft 24. The tension spring 18 is installed on the tension shaft 19, one end of the tension spring 18 is limited and fixed through the rotating shaft nut 20, and the tension shaft 19 is provided with threads, so that the tension nut 20 is convenient to install. The tension of the tension spring 18 can be adjusted by rotating the tension nut 20. Under the action of the tension spring 18, the tension plate 17 is pushed to always keep close contact with the sleeve 23, and the tension of the tension plate 17 and the cross beam 13 fixedly connected with the tension plate 17 is realized.
As shown in fig. 8, a tension pulley 21 and a second fixing plate 22 are disposed between the tension plate 17 and the tension spring 18, the tension pulley 21 is located between the tension plate 17 and the second fixing plate 22, and the second fixing plate 22 is fixedly connected to the tension spring 18.
When the tensioning mechanism works, displacement is generated between the tensioning plate 17 and the tensioning spring 18, the acting force of the tensioning spring 18 is large, the relative sliding resistance between the tensioning plate 17 and the tensioning spring 18 is large, and therefore the adjustment sensitivity of tensioning is not high, the tensioning pulley 21 and the second fixing plate 22 are arranged between the tensioning plate 17 and the tensioning spring 18, the friction resistance between the tensioning plate 17 and the tensioning spring 18 is changed into the sliding resistance between the tensioning pulley 21 and the tensioning plate 17 or the second fixing plate 22, the resistance is reduced, the adjustment sensitivity of tensioning force is improved, the tensioning mechanism is used for secondary compensation of a scraper, and therefore the sensitivity of the sweeper to scraper compensation is also improved.
As shown in fig. 9, the tension pulley 21 is rotatably disposed on the second fixing plate 22, and the tension pulley 21 is in contact with the tension plate 17 and is rotatable relative to the tension plate 17.
The tension pulley 21 is fixedly mounted on the second support plate 27 of the second fixing plate 22 through a bolt, a rotating shaft or a pin shaft, the tension pulley 21 is fixedly mounted, when the tension plate 17 rotates, relative sliding can be generated between the tension plate 17 and the tension pulley 21, at the moment, the rotation resistance of the tension pulley 21 is small, and therefore the sensitivity of tension force adjustment is improved.
As shown in fig. 9, the number of the tension pulleys 21 is even when the tension pulleys are installed, the rotation axes are overlapped, and the tension pulleys 21 are uniformly distributed on both sides of the tension shaft 19, in order to ensure the consistency of the rotation of the tension pulleys 21, the diameters of the tension pulleys 21 are the same, and the uniform distribution on both sides of the tension shaft 19 ensures the uniformity of the acting force of the second fixing plate 22 on the tension spring 18.
As shown in fig. 8, the axis of rotation of the tension plate 17 relative to the cross beam 13 and the axis of rotation of the tension pulley 21 are parallel to each other.
The tension pulley 21 can be mounted on the second fixing plate 22 by a bolt, a pin or a rotating shaft, and the axis of rotation of the tension plate 17 relative to the cross beam 13 and the axis of rotation of the tension pulley 21 are parallel to each other, so that when the tension plate 17 rotates along with the cross beam 13, the rotation resistance of the bolt, the pin or the rotating shaft to the tension pulley 21 is minimum. The rotation resistance of the tension pulley 21 itself is reduced to the maximum.
As shown in fig. 8, the tension plate 17 is a flat plate, and may be an arc plate or a bent plate.
Resistance becomes little when two arcwall faces rotate relatively, and tensioning plate 17 sets up to the arcwall, has further reduced the sliding resistance between tensioning pulley 21 and tensioning plate 17. The bending plate is a plate with a bending angle, and when the bending plate is installed, the bending part faces to one side of the tension pulley 21, so that the sliding resistance between the tension pulley 21 and the tension plate 17 can be reduced during compensation.
Example six:
as shown in fig. 10, the difference between the present embodiment and the fifth embodiment is: the tension pulley 21 is rotatably disposed on the tension plate 17, and the tension pulley 21 is in contact with the second fixing plate 22 and is rotatable relative to the second fixing plate 22.
The tension pulley 21 is fixedly installed on the second supporting plate 27 on the tension plate 17 through a bolt, a rotating shaft or a pin shaft, the tension pulley 21 is fixedly installed, when the tension plate 17 rotates, relative sliding can be generated between the second fixing plate 22 and the tension pulley 21, at the moment, the rotation resistance of the tension pulley 21 is small, and therefore the sensitivity of tension force adjustment is improved.
