Description

Technical Field

[0001] This utility model relates to the technical field of belt conveyor equipment, and in particular to a conveyor belt cleaning device. Background Technology

[0002] The discharge port of the silo is usually connected to a belt conveyor. During operation, the conveyor belt inevitably leaves residual material, which requires frequent cleaning. After the material is conveyed by the belt conveyor, some of it will stick to the conveyor belt. The upper conveyor belt rotates from the discharge roller to the lower part, and the material stuck to the conveyor belt rotates to the bottom of the belt. If the material has high moisture content, it can easily cause the belt conveyor to be overloaded, resulting in equipment damage. In addition, the stuck material will fall off one after another during the rotation, which is not convenient to clean and wastes manpower and resources. Utility Model Content

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0028] like Figure 1-2As shown, one embodiment of this utility model is as follows: The conveyor belt cleaning device includes a fixed frame 1, with rollers 2 rotatably mounted on the left and right ends of the fixed frame 1, and a conveyor belt 3 wound between the two rollers 2. A reduction motor is mounted on the fixed frame 1, which drives one of the rollers 2 to rotate, thereby causing the conveyor belt 3 to rotate cyclically. The conveyor belt cleaning device also includes a cleaning device 4 disposed on the bottom surface of the fixed frame 1. The cleaning device 4 includes: a support base 41, a swing arm 42, a roller brush 43, a drive assembly 44, and a motor 45. The support base 41 is disposed on the bottom surface of the fixed frame 1; the left end of the swing arm 42 is connected to the... The support base 41 is rotatably connected; the roller brush 43 is rotatably mounted on the right end of the swing arm 42; the drive assembly 44 is mounted on the support base 41, and its working end is rotatably connected to the swing arm 42 to drive the swing arm 42 to rotate, so that the roller brush 43 moves closer to or away from the conveyor belt 3; the motor 45 is mounted on the swing arm 42, and its output end is connected to the roller brush 43 for driving the roller brush 43 to rotate. It can be understood that the output end of the motor 45 is provided with a first pulley, and the rotating shaft of the roller brush 43 is provided with a second pulley. Of course, the motor 45 and the roller brush 43 can also be connected to the chain drive via a sprocket.

[0029] In this embodiment, a first pulley is provided at the output end of the motor 45, and a second pulley is provided on the rotating shaft of the roller brush 43. The first pulley and the second pulley are connected by a belt. When the conveyor belt 3 needs to be cleaned, the drive assembly 44 drives the right end of the swing arm 42 to move closer to the bottom surface of the conveyor belt 3, so that the roller brush 43 contacts the bottom surface of the conveyor belt 3. The motor 45 drives the roller brush 43 to rotate, sweeping off the material adhering to the surface of the conveyor belt 3, preventing the material from sticking together and causing the belt conveyor to be overloaded, resulting in equipment damage.

[0030] In one embodiment, such as Figure 2 As shown, the drive assembly 44 includes a connecting seat 46 and a cylinder 47. The left end of the connecting seat 46 is rotatably mounted on the support seat 41, and its right end extends to the right. The fixed end of the cylinder 47 is rotatably connected to the right end of the connecting seat 46, and its working end is rotatably connected to the swing arm 42. During operation, the cylinder 47 extends to drive the swing arm 42 to rotate, causing the right end of the swing arm 42 to move upward, thereby causing the roller brush 43 to contact the conveyor belt 3 and sweep off the material on the lower surface of the conveyor belt 3. When the roller brush 43 needs maintenance and replacement, the cylinder 47 retracts, and the right end of the swing arm 42 moves downward, causing the roller brush 43 to move away from the conveyor belt 3.

[0031] In one embodiment, such as Figure 1 , Figure 3 As shown, the conveyor belt cleaning device also includes an air blowing device 5. The air blowing device 5 includes a mounting base 51, an adjusting screw 52, ​​and an air blowing assembly 53. The mounting base 51 is disposed on the bottom surface of the fixed frame 1. One end of the air blowing assembly 53 is slidably connected to the mounting base 51. The adjusting screw 52 is rotatably disposed in the mounting base 51 and is spirally connected to the air blowing assembly 53.

[0032] In this embodiment, the air blowing device 5 and the cleaning device 4 can be used simultaneously or separately. When the material has low moisture content, only the air blowing device 5 can be turned on to reduce the wear of the roller brush 43. By rotating the adjusting screw 52, ​​the distance between the air blowing assembly 53 and the conveyor belt 3 can be adjusted to adapt to different material conditions.

[0033] In one embodiment, such as Figure 4 As shown, the air blowing assembly 53 includes an air pipe 531 and multiple nozzles 532. The length direction of the air pipe 531 is consistent with the width direction of the conveyor belt 3. The multiple nozzles 532 are arranged at intervals along the length direction of the air pipe 531 and are connected to the air pipe 531 respectively. The dust adhering to the surface of the conveyor belt 3 is blown off by the multiple nozzles 532 along the width direction of the conveyor belt 3.

[0034] In one embodiment, such as Figure 4 As shown, the air blowing assembly 53 also includes a slider 533, which is slidably disposed in the mounting base 51 and is screwed to the adjusting screw 52. One end of the air pipe 531 is fixedly connected to the slider 533. By rotating the adjusting screw 52, ​​the slider 533 is driven to slide along the mounting base 51, thereby adjusting the distance between the air pipe 531 and the conveyor belt 3.

[0035] In one embodiment, such as Figure 5 As shown, a slide 511 is provided in the mounting base 51, and a through groove 512 communicating with the outside is provided on one side of the slide 511. The slider 533 is slidably connected to the slide 511. The through groove 512 is suitable for the passage of the vent pipe 531. In this embodiment, the slide 511 is opened along the length direction of the mounting base 51, and the width of the slide 511 is greater than the width of the through groove 512 to prevent the slider 533 from falling off.

[0036] In one embodiment, such as Figure 4 As shown, the end of the vent pipe 531 away from the mounting base 51 is connected to a solenoid valve 534. The input end of the solenoid valve 534 is connected to external high-pressure gas, and the solenoid valve 534 is used to control the on / off of the high-pressure gas.

[0037] In one embodiment, such as Figure 1 As shown, it also includes a dust collection hood 6, which is located above the cleaning device 4. The dust collection hood 6 is connected to an external dust collector, which collects dust floating in the air through the dust collection hood 6 to prevent environmental pollution.

[0038] In one embodiment, such as Figure 1 As shown, it also includes a dust collection bin 7, which is located below the cleaning device 4 and is used to collect materials dropped from the cleaning device 4 and the air blowing device 5.

[0039] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this utility model specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims of this utility model.
