Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1 and 2, a conveying belt cleaning structure of a shield muck belt conveyor, wherein a first scraper 3 and a second scraper 4 are sequentially arranged at a belt pulley 1 at the output end of the shield muck belt conveyor along the transmission direction of a belt 2; wherein a gap exists between the first scraper 3 and the belt 2, and the second scraper 4 is kept in close contact with the belt 2 by an elastic element 6 arranged on a belt conveyor frame 5.
The utility model discloses set up one fixed scraper blade on shield structure dregs belt conveyor and compress tightly the activity scraper blade at the belt surface through elastic element 6 effects together, the twice scraper blade can scrape the belt surface dregs basically whole, and then improves belt conveyor's the ability of slagging tap.
Specifically, first scraper blade 3 is located 1 upper right side of belt pulley and is 3cm with 2 surperficial distances in the belt, and first scraper blade 3 adopts arc alloy scraper blade to with 5 inner wall fixed connection of band conveyer frame, above-mentioned first scraper blade 3 can be scraped most dregs and bold gravel dregs. The second scraper blade 4 adopts the polyurethane scraper blade to make through the effect of elastic element 6 and keep certain pressure contact between polyurethane scraper blade and the belt all the time, improved and scraped the sediment effect. In addition, the high polymer polyurethane material has the characteristics of low friction coefficient, high wear resistance, corrosion resistance, high strength and no damage to the belt, and the polyurethane scraper can improve the slag scraping effect and prolong the service life of the scraper structure.
Referring to fig. 2 and fig. 3, in some embodiments, a specific connection structure between the second scraper 4, the elastic element 6 and the frame is provided, the second scraper 4 is located at the lower right of the belt pulley 1 and has a scraper shaft 7 at one end away from the belt pulley 1, the second scraper 4 is rotatably mounted on the frame 5 through the scraper shaft 7, two ends of the scraper shaft 7 are fixedly provided with a baffle 8 extending in a direction away from the belt pulley 1, one end of a pin 9 is fixedly connected with the baffle 8, the other end is fixedly connected with the frame 5, a coil spring in a compressed state is sleeved on the pin 9 between the baffle 8 and the frame, that is, the elastic element 6, the scraper shaft 7 is driven to rotate around its own axis by an elastic force provided by the coil spring, and then the second scraper 4 is driven to rotate relative to the frame, so that one end of the second scraper 4 away from the scraper shaft 7 is only abutted to the belt, maintaining intimate contact.
Referring to fig. 4 and 5, in other embodiments, considering that the belt is made into rough surfaces for improving slag carrying effect, and the tiny pits of the rough surfaces are easy to accumulate slag soil, and cannot be completely removed by the slag scraping plate, a nozzle 10 aligned with the belt can be further arranged on the belt conveyor frame 5 behind the second scraper 4, the nozzle 10 is connected with a pressure water source through a water inlet pipe 11, and the pressure water sprayed by the nozzle 10 can wash away the slag soil accumulated in the tiny pits on the belt surface.
Specifically, in order to realize the comprehensive cleaning of the belt, the nozzles 10 are arranged in rows along the width direction of the belt, in practical application, the direction of the spray heads can form an included angle of 50 degrees with the horizontal direction of the belt, and the distance between the spray heads and the lower surface of the belt is 5 cm.
This embodiment sets up one fixed scraper blade, compresses tightly the polyurethane scraper blade and one nozzle on the belt surface through the spring action together to shield structure dregs conveyor belt because of shield structure dregs viscidity is stronger, easily appears scraping unclean problem.
