Abstract
Description
Technical Field
[0001] This utility model relates to the field of scraper cleaning, specifically a scraper cleaning device for a coal mining transfer machine. Background Technology
[0002] In the coal mining industry, coal transfer machines are key equipment in the coal transportation process, and scrapers are important components of the transfer machines for material conveying. When working, scrapers are in constant contact with coal and other materials, and a large amount of residual material will inevitably remain on their surface.
[0003] Traditional scrapers are usually not cleaned or rely on manual cleaning, which is ineffective and leaves a lot of material on the scraper surface. The accumulated residue will increase the weight of the scraper, increase the operating load of the equipment, and thus affect the working efficiency of the transfer machine. It may also cause energy waste. In addition, manual cleaning also poses certain safety risks. Workers are prone to injury when working in harsh environments. Therefore, it is necessary to design a scraper cleaning device for coal mining transfer machines to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a scraper cleaning device for a coal mining transfer machine to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a scraper cleaning device for a coal mining transfer machine, comprising a conveying trough, a driving device being provided inside the conveying trough, a scraper chain being driven on the outside of the driving device, and a plurality of scrapers being installed on both the front and rear sides of the scraper chain.
[0006] Mounting plates are installed on both the front and rear sides of the top of the conveying trough. Lifting rods are slidably installed inside the mounting plates. Elastic components connected to the mounting plates are provided at the top of the lifting rods. U-shaped brackets are installed at the lower ends of the two lifting rods. Connecting plates are installed on the bottom surface of the U-shaped brackets. Multiple mounting holes are opened on the surface of the connecting plates. Multiple vibration transmission components for resisting the scraper are provided inside the mounting holes. Vibration motors are installed inside the U-shaped brackets.
[0007] Preferably, the driving device includes multiple motors, which are installed on the outside of the conveying trough. Multiple transmission wheels are fixedly installed at the output end of the motors, and the scraper chain drive is located on the outside of the multiple transmission wheels.
[0008] Preferably, the elastic component includes a baffle plate, which is fixedly installed on the upper end of the lifting rod, and a spring is fixedly installed on the bottom surface of the baffle plate, with the lower end of the spring fixedly installed on the top surface of the mounting plate.
[0009] Preferably, the spring surrounds the outside of the lifting rod.
[0010] Preferably, the vibration transmission component is a contact wheel, which is rotatably installed inside the mounting hole.
[0011] Preferably, the abutment wheel is cylindrical.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. The scraper cleaning device used in this coal transfer machine allows the scraper to move to contact the contact wheel during the conveying process. Turning on the vibrating motor causes the vibrating motor, U-shaped support, and connecting plate to vibrate. The vibration is transmitted through the connecting plate to the contact wheel, causing the scraper to vibrate and shaking off the coal ash adhering to its surface. The shaken-off coal ash falls back into the lower part of the conveying trough and is then conveyed along with the coal ash to the outlet of the conveying trough. This facilitates the cleaning of coal ash adhering to the scraper surface and effectively reduces the load on the transfer machine.
[0014] 2. The scraper cleaning device for this coal mining transfer machine has a spring installed between the baffle and the mounting plate. The spring has a tendency to pull the baffle downward, which causes the baffle, U-shaped support, connecting plate and contact wheel to move downward as well. This ensures that the contact wheel can make contact with the scraper, so that vibration can be transmitted to the scraper. The rolling design of the contact wheel can reduce the friction between the scraper and the contact wheel and reduce equipment wear. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1
[0021] Please refer to Figure 1-3 As shown, this utility model provides a scraper cleaning device for a coal mining transfer machine, including a conveying trough 1, a driving device is installed inside the conveying trough 1, a scraper chain 4 is driven on the outside of the driving device, and several scrapers 5 are installed on both the front and rear sides of the scraper chain 4.
[0022] Mounting plates 6 are installed on both the front and rear sides of the top of the conveying trough 1. Lifting rods 7 are slidably installed inside the mounting plates 6. The top of the lifting rods 7 is provided with an elastic component connected to the mounting plates 6. U-shaped brackets 8 are installed at the lower ends of the two lifting rods 7. A connecting plate 12 is installed on the bottom surface of the U-shaped brackets 8. Multiple mounting holes 13 are opened on the surface of the connecting plate 12. Multiple vibration transmission components for resisting the scraper 5 are provided inside the mounting holes 13. A vibration motor 11 is installed inside the U-shaped brackets 8.
[0023] Specifically, during the conveying process, the scraper 5 can move to contact the contact wheel 14, turn on the switch of the vibration motor 11, and cause the vibration motor 11, U-shaped bracket 8, and connecting plate 12 to vibrate. The vibration is transmitted to the contact wheel 14 through the connecting plate 12 and drives the scraper 5 to vibrate, thereby shaking off the coal ash attached to the surface of the scraper 5.
[0024] The drive device includes multiple motors 2, which are installed on the outside of the conveying trough 1. Multiple transmission wheels 3 are fixedly installed at the output end of the motors 2. The scraper chain 4 is driven on the outside of the multiple transmission wheels 3. When the switch of the motor 2 is turned on, the transmission wheels 3 are driven to rotate, and the transmission wheels 3 drive the scraper chain 4 and the scraper 5 to move.
[0025] The elastic component includes a baffle 9, which is fixedly installed on the upper end of the lifting rod 7. A spring 10 is fixedly installed on the bottom surface of the baffle 9. The lower end of the spring 10 is fixedly installed on the top surface of the mounting plate 6. The spring 10 surrounds the outside of the lifting rod 7. The spring 10 has a tendency to pull the baffle 9 downward, so that the baffle 9, the U-shaped bracket 8, the connecting plate 12 and the abutment wheel 14 all have a tendency to move downward.
[0026] Specifically, the vibration transmission component is the contact wheel 14, which is rotatably installed inside the mounting hole 13. The contact wheel 14 is cylindrical and its rolling design can reduce the friction between the scraper 5 and the contact wheel 14, thereby reducing equipment wear.
[0027] Working principle: This utility model is a scraper cleaning device for a coal transfer machine. When the transfer machine is processing, the switch of motor 2 is turned on, which drives the transmission wheel 3 to rotate. The transmission wheel 3 drives the scraper chain 4 and scraper 5 to move. The scraper 5 can push the coal in the conveying trough 1 to the outlet position. The scraper 5 moves to the upper part of the conveying trough 1 with the scraper chain 4 and can move to contact the contact wheel 14. The switch of vibrating motor 11 is turned on, which causes the vibrating motor 11, U-shaped bracket 8 and connecting plate 12 to vibrate. The vibration is transmitted to the contact wheel 14 through the connecting plate 12 and drives the scraper 5 to vibrate, thereby shaking off the coal dust attached to the surface of the scraper 5. The shaken coal dust will fall back to the lower part of the inner cavity of the conveying trough 1, and thus continue to be conveyed to the outlet position of the conveying trough 1 along with the conveyed coal dust. This facilitates the cleaning of the coal dust attached to the surface of the scraper 5 and effectively reduces the load on the transfer machine.
[0028] A spring 10 is installed between the baffle 9 and the mounting plate 6. The spring 10 has a tendency to pull the baffle 9 downward, so that the baffle 9, the U-shaped bracket 8, the connecting plate 12 and the contact wheel 14 all have a tendency to move downward, thereby ensuring that the contact wheel 14 can abut against the scraper 5, so that vibration can be transmitted to the scraper 5. The rolling design of the contact wheel 14 can reduce the friction between the scraper 5 and the contact wheel 14, and reduce equipment wear.
