Meanwhile, since the size of the carriage 2 is generally large, in order to improve the sliding stability of the carriage, the first guide rod 21 is fixed on the carriage 2, and the first guide sleeve (not shown in the figure) which is used for the first guide rod 21 to pass through and is matched with the first guide rod is fixedly installed on the frame 1, so that the sliding movement of the carriage 2 is more stable.
The sliding frame 2 is rotatably connected with a roll shaft 3, for example, bearings are arranged at two ends of the roll shaft 3, so that the sliding frame 2 is rotatably connected with two ends of the sliding frame 2 through the bearings; evenly be provided with the flexible brush silk of a plurality of on the circumference outer wall of roller 3 to form the brush roll, usually, the flexible brush silk is the steel wire, and flexible brush silk contacts with the cylinder screen that treats the clearance when using, thereby clears up the material that blocks up in the mesh. The axis of the roller shaft 3 is generally set perpendicular to the sliding direction of the carriage 2.
A power device for driving the roller shaft 3 to rotate is fixedly arranged on the sliding frame 2, and the power device comprises a base 4, a motor 5 and a speed reducer 6 which are arranged on the base 4. The base 4 is slidably connected to the carriage 2 and fixed by a locking mechanism 41, for example, a linear slide rail is fixed to the carriage 2, and a slide groove adapted to the linear slide rail is provided on the base 4, so that the base 4 can slide on the carriage 2, and the linear slide rail is provided in a direction parallel to the axis of the roller shaft 3. In this embodiment, the locking mechanism 41 is configured as a pin, and the base 4 is specifically locked by providing a through pin hole on the base 4 and also providing a pin hole on the carriage 2, and the pin passes through the pin hole on the base 4 and penetrates through the pin hole on the carriage 2 to fix the base 4 at a working position, which is a position where the motor 5 can drive the roller shaft 3 to rotate. Alternatively, in another embodiment, the locking mechanism 41 may be configured as a locking screw, and a through threaded hole is provided in the base 4, and after the locking screw is screwed into the threaded hole, the base 4 is fixed by a frictional force generated by abutting against the carriage 2.
The motor 5 is mechanically connected to the input of the reducer 6, for example, a coupling, but in another embodiment, the motor and the reducer may be connected through a gear transmission mechanism; meanwhile, the output end of the speed reducer 6 is connected with the roller shaft 3 through an Oldham coupling, and the arrangement of the Oldham coupling enables the speed reducer 6 to be smoothly connected with or disconnected from the roller shaft 3 when the base 4 slides.
The rack 1 is further slidably connected with a push plate 7, the sliding direction of the push plate 7 is parallel to the sliding direction of the carriage 2, and in this embodiment, by means of the first guide rod 21, a first guide sleeve is arranged on the push plate 7, so as to ensure the sliding connection of the push plate 7 with respect to the rack 1. Meanwhile, a compression spring 8 is connected between the push plate 7 and the sliding frame 2, the rack 1 is also in threaded connection with an adjusting screw rod 9, and the tail end of the adjusting screw rod 9 is abutted against the push plate 7. So set up for through revolving to twist adjusting screw 9 and promote push pedal 7 and compression spring 8 motion, thereby exert certain elasticity to balladeur train 2, guarantee the pressure that the cylindrical sieve that the clearance was treated to the flexible brush silk on it.
When in use, firstly, the frame 1 is usually fixedly arranged on the frame body of the cylindrical screen, and the axis of the roll shaft 3 is ensured to be parallel to the axis of the cylindrical screen; screwing an adjusting screw 9, driving the sliding frame 2 to slide through a push plate 7 and a compression spring 8, enabling the flexible brush wires to be in contact with and pressed on the cylindrical screen, and adjusting and controlling the pressure of the flexible brush wires on the cylindrical screen through the adjusting screw 9; then, the base 4 is slid, the output end of the speed reducer 6 is connected with the roller shaft 3, and then the base 4 is locked and fixed through a locking mechanism; when the drum screen rotates to screen, the synchronous starting motor 5 rotates to drive the roller shaft 3 to rotate, and the flexible brush wires can perform synchronous cleaning work on meshes of the drum screen in the working process of the drum screen, so that the meshes are not blocked. Therefore, in the cleaning operation of the meshes, the impact and the damage to the screening equipment can not be caused, and meanwhile, the machine does not need to be stopped, so that the production efficiency is favorably kept.
Example two
The difference from the first embodiment is that: as shown in fig. 2, in the present embodiment, a fixed friction disk 10 is attached to the roller shaft 3, a movable friction disk 11 is slidably connected to the carriage 2, the sliding direction of the movable friction disk 11 is parallel to the axis of the roller shaft 3, a pressure screw 12 is screwed to the carriage 2, and the pressure screw 12 is in contact with the movable friction disk 11 via a pressure spring 13.
Specifically, a second guide rod 22 is fixed to the carriage 2, a second guide sleeve (not shown) adapted to the second guide rod 22 is mounted on the movable friction disk 11, a pressure plate 14 is further slidably connected to the second guide rod 22, the pressure spring 13 is fixedly connected between the movable friction disk 11 and the pressure plate 14, and the pressure screw 12 abuts against the pressure plate 14. That is, the movable friction disk 11 is located between the fixed friction disk 10 and the pressure plate 14, and the second guide bush described above is also provided on the pressure plate 14 so as to be slidable on the second guide rod 22.
So set up for through the operation promotion pressure strip 14 motion of twisting the pressure screw 12, pressure strip 14 extrusion pressure spring 13, thereby to the elasticity of applying to activity friction disk 11, this elasticity makes the frictional force increase between activity friction disk 11 and the fixed friction disk 10, thereby guarantees under unpowered condition (base 4 slides the back, reduction gear 6 is not connected with roller 3), can reduce the rotational speed of roller 3 through this operation, makes the flexible brush silk can be better stretch into the mesh and carry out the cleaning operation.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, and the scope of protection is still within the scope of the invention.
