Description

Technical Field

[0001] The invention relates to the technical field of conveying equipment, and in particular to an adjustable scraper and an anti-winding tail wheel sweeper. Background Art

[0002] At present, during the working process of the belt conveyor, the tail roller of the belt conveyor often sticks to the material, causing the belt to deviate, and at the same time, the tail roller is prone to entanglement accidents. At present, for cleaning the tail roller of the belt conveyor, a scraper is generally used to scrape off impurities, and then the impurities are removed by a processing device. For example, the published patent 2018222147562 discloses a belt conveyor bottom sweeper arch-breaking scraper. After the material on the belt is scraped off by the scraper, it is easy to form an arch at the bottom of the belt. After the arch is dredged by the arch-breaking scraper, it is taken out of the sweeper by the scraper, thereby achieving the purpose of breaking the arch. However, in the above action, the material is easily stuck in the gap between the roller and the scraper due to the action of the scraper, which is easy to cause equipment damage over time. Therefore, it is particularly important to solve the problem of impurity residues caused by ordinary scraper impurity removal. Summary of the invention

[0003] The purpose of the present invention is to provide an adjustable scraper and an anti-roll tail wheel sweeper, which can scrape impurities on the tail roller by means of a cleaning scraper, and at the same time, can suck the impurities away from above by means of a cleaning nozzle, so that the impurities will not fall on the equipment or in the gaps, thereby avoiding damage to the equipment. At the same time, the space occupied by the sweeper bracket and the arc plate thereon are utilized to eliminate the space that is easily rolled up, thereby solving the problem that impurities are easily left behind when ordinary scrapers are used for impurity removal.

[0004] The present invention provides an adjustable scraper and an anti-winding tail wheel sweeper, comprising a cleaning scraper arranged next to the tail roller of a belt conveyor, wherein a fastener is arranged at one end of the cleaning scraper, and the other end of the cleaning scraper is arc-shaped and consistent with the curvature of the tail roller, and the arc-shaped part of the cleaning scraper is arranged close to the drum edge of the tail roller, and an adjusting screw is arranged on one side of the fastener, and the distance between the fastener and the tail roller is adjusted by rotating the adjusting screw, thereby adjusting the distance between the arc-shaped part of the cleaning scraper and the tail roller.

[0005] A further improvement is that a close contact spring is provided between the fastener and the cleaning scraper, and the cleaning scraper is made to close contact with the tail roller by the close contact spring.

[0006] A further improvement is that a cleaning nozzle is arranged above the cleaning scraper, and a vacuum cleaner is connected to the rear end of the cleaning nozzle. The vacuum cleaner generates negative pressure at the lower end of the cleaning nozzle to collect impurities scraped off the cleaning scraper.

[0007] A further improvement is that a lifting cylinder is arranged on the side of the cleaning nozzle, and the lifting cylinder drives the cleaning nozzle to move downward to expand the cleaning range.

[0008] A further improvement is that the vacuum cleaner connected to the cleaning nozzle is reversed, and air is blown through the cleaning nozzle to blow away impurities adhering to the cleaning scraper.

[0009] A further improvement is that a vibration motor is arranged on the fastener, and vibration is generated by the vibration motor, and the vibration is transmitted to the close-fitting spring, thereby vibrating the cleaning scraper and shaking off the impurities on the cleaning scraper.

[0010] The beneficial effects of the present invention are as follows: impurities on the tail roller are scraped off by the cleaning scraper, and impurities are sucked away from above by the cleaning nozzle, and will not fall on the equipment and in the gaps, thereby avoiding damage to the equipment. At the same time, the space occupied by the sweeper bracket and the arc plate thereon are utilized to eliminate the space that is easy for people to be rolled up, thereby avoiding the occurrence of potential safety hazards. The cleaning nozzle moves downward under the drive of the lifting cylinder, thereby expanding the cleaning range and improving the cleaning effect. At the same time, the vacuum cleaner works in reverse when necessary to blow off impurities, and at the same time, a vibration motor is used to vibrate the cleaning scraper to remove impurities adhered to the cleaning scraper, thereby avoiding the impurities adhered to the cleaning scraper, thereby preventing the scraping effect from being reduced and damaging the tail roller.

[0013] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0014] like Figure 1As shown, this embodiment provides an adjustable scraper and an anti-winding tail wheel cleaner, including a cleaning scraper 2 arranged beside the tail roller 1 of the belt conveyor, a fastener 3 is arranged at one end of the cleaning scraper 2, the other end of the cleaning scraper 2 is arc-shaped and consistent with the arc of the tail roller 1, the arc-shaped part of the cleaning scraper 2 is arranged close to the drum edge of the tail roller 1, and an adjusting screw 4 is arranged on one side of the fastener 3. By rotating the adjusting screw 4, the distance between the fastener 3 and the tail roller 1 is adjusted, thereby adjusting the distance between the arc-shaped part of the cleaning scraper 2 and the tail roller 1. A close contact spring 5 is arranged between the fastener 3 and the cleaning scraper 2, and the cleaning scraper 2 is made to close to the tail roller 1 by the close contact spring 5. A cleaning suction nozzle 6 is arranged above the cleaning scraper 2, and a vacuum cleaner is connected to the rear end of the cleaning suction nozzle 6. The vacuum cleaner generates negative pressure at the lower end of the cleaning suction nozzle 6 to collect impurities scraped off by the cleaning scraper 2. A lifting cylinder 7 is provided on the side of the cleaning nozzle 6, and the lifting cylinder 7 drives the cleaning nozzle 6 to move downward to expand the cleaning range. The vacuum cleaner connected to the cleaning nozzle 6 is reversed, and air is blown through the cleaning nozzle 6 to blow away the impurities adhered to the cleaning scraper 2. A vibration motor 8 is provided on the fastener 3, and the vibration is generated by the vibration motor 8. The vibration is transmitted to the close spring 5, thereby vibrating the cleaning scraper 2, so that the impurities on the cleaning scraper 2 are shaken off. The impurities on the tail roller 1 are scraped off by the cleaning scraper 2, and the impurities are sucked away from the top by the cleaning nozzle 6, so that they will not fall on the equipment and in the gaps, thereby avoiding damage to the equipment. At the same time, the space occupied by the sweeper bracket and the arc plate thereon are used to eliminate the space that is easy for people to be rolled up, thereby avoiding the occurrence of safety hazards. The cleaning nozzle 6 moves downward under the drive of the lifting cylinder 7 to expand the cleaning range and improve the cleaning effect. At the same time, when necessary, the vacuum cleaner works in reverse to blow away the impurities. At the same time, the vibration motor 8 is used to vibrate the cleaning scraper 2 to remove the impurities adhered to the cleaning scraper 2, thereby avoiding the impurities adhered to the cleaning scraper 2, resulting in a decrease in the scraping effect and damage to the tail roller 1.
