Description

Technical Field

[0001] This invention relates to the field of cleaning devices, specifically a cleaning device that automatically controls the blade to adhere to and detach from the belt surface. Background Technology

[0002] A cleaner is a device used to clean residual materials on a conveyor. During the conveying process of a belt conveyor, if residual materials enter the bearing housing of the rollers or idlers, it will accelerate the wear of the bearings. Materials stuck to the surface of the rollers or idlers will tear and fray the conveyor belt adhesive, accelerating the wear and damage of the conveyor belt. Therefore, the use of a cleaner is particularly important.

[0003] Currently, existing sweepers maintain a fixed angle between the sweeper blades and the conveyor belt for easy integration with conveyors. However, in actual use, the rollers sometimes detach from the frame on which the sweeper is installed, requiring the blades to disengage from the conveyor belt, such as on a stacker-reclaimer belt conveyor. Furthermore, the conveyor belt sometimes needs to rotate in both directions, requiring the sweeper blades to disengage from the belt during rotation. This necessitates manual adjustment of the sweeper blade position and angle, a cumbersome, time-consuming, and labor-intensive process. Therefore, we propose a sweeper that automatically controls the blades' contact with and disengagement from the belt surface. Summary of the Invention

[0004] The purpose of this invention is to provide a cleaner that automatically controls the blades to adhere to and detach from the belt surface. This invention offers the advantage of automatically controlling the blades' contact with and detachment from the belt surface, solving the problem of existing cleaners where, for ease of use with conveyors, the cleaner blades maintain a fixed angle with the conveyor belt. However, in actual use, the rollers sometimes detach from the frame where the cleaner is installed, requiring the blades to disengage from the conveyor belt, such as on a stacker-reclaimer belt conveyor. Furthermore, the conveyor belt sometimes needs to rotate in both directions, requiring the cleaner blades to disengage from the belt during rotation. This necessitates manual adjustment of the cleaner blade position and angle, making the operation cumbersome, time-consuming, and labor-intensive.

[0027] Please see Figure 1-5A cleaning device that automatically controls the blade's contact with and detachment from the belt surface includes a right mounting plate 1, a left mounting plate 7, a fixing rod 12, and a bearing seat 15. A fixing sleeve 16 is fixedly connected to one end of the outer surface of the fixing rod 12. A blade holder plate 2 is fixedly connected to the front surface of the fixing sleeve 16. A fixing plate 6 is fixedly connected to the upper end of the front surface of the blade holder plate 2. A guide bend 4 is provided between one end of the fixing plate 6 and the upper end of the blade holder plate 2. A rotating rod 14 is provided inside the bearing seat 15. The left and right ends of the rotating rod 14... Each is connected with a limit pin 20. A blade 9 is fixedly installed on the outer surface of the rotating rod 14. A countersunk hole 19 is opened on the inner surface of the lower end of the blade 9. A connecting pin 18 is provided on the inner side of the countersunk hole 19. A first cylinder 3 is fixedly installed on the lower end of the front surface of the tool holder plate 2. A first chain 5 is fixedly connected between the extended end of the first cylinder 3 and the connecting pin 18. A second cylinder 10 and a guide wheel seat 22 are fixedly installed on the upper end of the right side of the right mounting plate 1. A second chain 23 is fixedly installed on the extended end of the second cylinder 10.

[0028] The inner surfaces of the right mounting plate 1 and the left mounting plate 7 are both provided with adjustment slots 8. An adjustment plate 17 is fixedly installed on one side of the right mounting plate 1 and the left mounting plate 7 by bolts. A fixing ring 11 is fixedly connected to the middle of one side of the adjustment plate 17. A fixing rod 12 is fixedly connected to the inner side of the fixing ring 11, and the fixing rod 12 is movable inside the adjustment slot 8.

[0029] By adjusting the position and height of the adjusting plate 17 on one side of the right mounting plate 1 and the left mounting plate 7, the fixing rod 12 can slide in the adjusting groove 8. The change in the position of the fixing rod 12 can drive the blade holder plate 2 to move through the fixing sleeve 16, thereby facilitating the adjustment of the position and height of the blade 9 according to the actual use.

[0030] A connecting plate 24 is fixedly connected to the upper rear side of the tool holder plate 2, and a bearing seat 15 is fixedly installed on the rear side of the connecting plate 24.

[0031] Through the above technical solutions, the bearing seat 15 ensures smooth movement of the blade 9, and the connecting plate 24 increases the range of motion of the upper end of the blade 9.

[0032] The rear end of the connecting pin 18 is threaded with a connecting nut 21, and the connecting nut 21 is located inside the countersunk hole 19.

[0033] Through the above technical solutions, the length of the first chain 5 can be easily adjusted by the cooperation of the connecting nut 21 and the connecting pin 18, and all the blades 9 can move synchronously while maintaining a straight line.

[0034] The first chain 5 is adapted to the guide bend 4, and the first chain 5 moves inside the guide bend 4.

[0035] Through the above technical solutions, the guide bend 4 can guide and limit the movement of the first chain 5.

[0036] An air management line hole 13 is provided on the inner surface of the lower end of the right mounting plate 1, and the diameter of the air management line hole 13 is between five centimeters and ten centimeters.

[0037] Through the above technical solution, the air pipe of the first cylinder 3 can be centrally organized and guided by the setting of the air pipe hole 13, avoiding the air pipe from being too scattered and affecting the appearance.

[0038] A through hole 25 is provided on the inner surface of the upper end of the right mounting plate 1. The second chain 23 is wrapped around the outside of the guide wheel seat 22, and the second chain 23 passes through the through hole 25 and is installed on the upper end of the left mounting plate 7.

[0039] Through the above technical solutions, with the assistance of the guide wheel seat 22, the second chain 23 can be guided, reducing the wear rate of the second chain 23 during use.

[0040] The first chain 5 and the second chain 23 can be replaced with soft rope.

[0041] The above technical solutions allow for selective substitution based on actual conditions, thus improving the applicability of this cleaner.

[0042] In use, the cleaner is fixed to the frame by levers. The position and height of the adjusting plate 17 on one side of the right mounting plate 1 and the left mounting plate 7 are adjusted so that the fixing rod 12 can slide in the adjusting groove 8. The change in the position of the fixing rod 12 can drive the blade holder plate 2 to move via the fixing sleeve 16, thus facilitating the adjustment of the fit height between the blade 9 and the conveyor belt according to the actual use. When the blade 9 needs to be close to the conveyor belt, the first cylinder 3 is controlled by an external control solenoid valve to drive the first chain 5 to retract (the first cylinder 3 is a series of cylinders, and each first cylinder 3 can be set with a value to control the tension of the blade 9). The first chain 5 is connected by the connecting pin 18 and the connecting screw. The mother 21 drives the blade 9 to rotate inward around the rotating rod 14. At the same time, the external control solenoid valve controls the second cylinder 10 to extend the second chain 23. With the cooperation of the guide wheel seat 22 and the through hole 25, the second chain 23 that blocks the blade 9 is released. When it is necessary for the blade 9 to disengage from the conveyor belt, the external control solenoid valve controls the first cylinder 3 to extend and release the first chain 5. At the same time, the external control solenoid valve controls the second cylinder 10 to retract the second chain 23. With the cooperation of the guide wheel seat 22 and the through hole 25, the second chain 23 that blocks the blade 9 is tightened, thereby causing the blade 9 to rotate outward and reset around the rotating rod 14.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
