[0002] Belt conveyor is a common material conveying equipment, which consists of conveyor belt, drive device, tensioning device, support device, conveyor roller and transmission roller. Belt conveyor is usually used for horizontal or inclined conveying of various bulk materials or pieces of objects in industrial and mining enterprises, such as ore, coal, sand and gravel, grain, fertilizer, etc. It can play an important role in long-distance and large-volume transportation. In the process of conveying materials, there are often some residues or dust left on the surface of the conveyor belt. If not cleaned in time, these residues may accumulate on the belt conveyor, affecting the normal use of the conveyor. By using a surface scraper device, the residual materials can be effectively cleaned, the conveyor belt can be protected, and the service life can be extended.

[0003] Traditional belt conveyor surface scraper devices are mainly fixed by welding. Scrapers are usually made of wear-resistant materials such as rubber, polyurethane or metal to increase their service life and wear resistance. The scraper is fixed to the conveyor structure to keep it in contact with the conveyor belt surface, thereby achieving the cleaning process.

[0004] Although the traditional belt conveyor surface scraper device achieves a firm installation effect by welding, it does not take into account the problem that it is inconvenient to replace the scraper when it is worn. Therefore, a belt conveyor surface scraper device is proposed to solve the above problem. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a belt conveyor surface scraper device, which aims to improve the problem that the scrapers of the traditional belt conveyor surface scraper device in the prior art are connected by welding, so that they cannot be replaced due to later wear, and the scrapers on both sides are rigid and easily cause damage to the conveyor belt.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a belt conveyor surface scraper device, comprising a fixed frame 1, a conveyor belt 2 is arranged inside the fixed frame 1, a side ear 3 is fixedly connected to the side wall of the fixed frame 1, a rotating shaft 4 is rotatably connected between the side ears 3, a fixed plate 5 is fixedly connected to the side wall of the rotating shaft 4, a fixed column 6 is fixedly connected to the side wall of the fixed plate 5 on one side, a fixed rod 2 10 is fixedly connected to the side wall of the fixed frame 1 on one side, a fixed rod 1 9 is fixedly connected to the side wall of the rotating shaft 4 on one side, a first spring 11 is arranged between the fixed rod 1 9 and the fixed rod 2 10, a scraper 7 is arranged on the side wall of the fixed plate 5, a bolt 8 is threadedly connected to the inside of the scraper 7, and a side wall of the bolt 8 is threadedly connected to the inside of the fixed plate 5, a material receiving assembly is arranged on the side wall of the fixed frame 1 for receiving scraped waste, and the material receiving assembly comprises a material receiving frame 12, a side wall of the material receiving frame 12 is fixedly connected to the side wall of the fixed frame 1, and a leakage groove 13 is opened inside the material receiving frame 12;

[0033] During the operation of the conveyor belt 2, the impurities attached to its surface will move with the conveyor belt 2. When these impurities pass through the bottom of the right scraper 7, the firmly attached impurities will lift up the scraper 7 due to their strong attachment strength. This action will further drive the right fixed plate 5 to deflect through the rotating shaft 4. During the deflection, the first spring 11 will deform, so that the impurities that are not firmly attached can be separated from the surface of the conveyor belt 2. These loose impurities will fall into the inside of the receiving frame 12 connected to the bottom, and the first cleaning will be achieved. Subsequently, when the firmly attached impurities move away from the bottom of the right scraper 7, the first spring 11 will return to its original state, and the scraper 7 will be close to the side wall of the conveyor belt 2 again. In this way, the firmly attached impurities will move to the bottom of the left scraper 7 with the operation of the conveyor belt 2. When the firmly attached impurities move to the bottom of the left scraper 7, the scraper 7 will scrape them off the conveyor belt 2. Similarly, these impurities will fall into the inside of the receiving frame 12, and the second collection will be achieved. When the scraper is seriously worn, the scraper 7 can be disassembled and replaced by twisting the bolts.

[0034] Reference Figure 3 - Figure 4 The lower surface of the fixed frame 1 is fixedly connected to a fixed box 14, and a collecting box 15 is slidably connected inside the fixed box 14. A connecting pipe 16 is fixedly connected inside the fixed box 14, and a connecting bucket 17 is fixedly connected to one end of the connecting pipe 16. The side wall of the connecting bucket 17 is fixedly connected to the lower surface of the receiving frame 12. A fan 18 is fixedly connected to the lower surface of the fixed frame 1, and a connecting pipe 2 19 is fixedly connected to the input end of the fan 18. The side wall of the connecting pipe 2 19 penetrates the side wall of the fixed box 14 and extends to the inside. The connecting pipe 2 A filter plate 20 is fixedly connected inside 19, a connecting plate 21 is fixedly connected to the lower surface of the fixed box 14, a pull rod 22 is slidably connected inside the connecting plate 21, a side wall of the pull rod 22 is fixedly connected to a limiting plate 23, a side wall of the pull rod 22 is sleeved with a second spring 24, one end of the second spring 24 is fixedly connected to the side wall of the limiting plate 23, the other end of the second spring 24 is fixedly connected to the side wall of the connecting plate 21, a latch 25 is rotatably connected to the side wall of the pull rod 22, and the side wall of the latch 25 is slidably connected to the inside of the collection box 15.

[0035] The suction force generated by starting the fan 18 is transmitted to the material receiving frame 12, thereby sucking the impurities into the collection box 15. When the work is completed, the pull pin 25 is pulled to make the pull rod 22 slide inside the connecting plate 21. This process will cause the second spring 24 to be squeezed and contracted, thereby pulling the upper end of the plug 25 out of the collection box 15. Next, the collection box 15 is pulled out from the fixed box 14 to clean the collected impurities. After cleaning, the collection box 15 is put back into the fixed box 14. At this time, the plug 25 is pulled again and rotated to reinsert the plug 25 into the collection box 15 to restrict it.

[0036] Working principle: When the conveyor belt 2 is working, when the impurities attached to the surface of the conveyor belt 2 pass through the bottom of the right scraper 7, the firmly attached impurities will lift up the right scraper 7 and make the right fixed plate 5 deflect through the rotating shaft 4, causing the first spring 11 to deform. At this time, the impurities that are not firmly attached will fall into the material receiving frame 12 connected to the bottom. When the firmly attached impurities move away from the bottom of the right scraper 7, the first spring 11 will reset at this time, making the scraper 7 fit the side wall of the conveyor belt 2 again. The firmly attached impurities move with the conveyor belt 2. When they move to the bottom of the left scraper 7, the scraper 7 will scrape them off the conveyor belt 2 and also make them fall into the material receiving frame 12. The impurities collected in the receiving frame 12 are collected inside the collecting box 15, and then suction is generated by starting the fan 18. The impurities collected inside the receiving frame 12 are extracted through the connecting pipe 16 and sucked into the collecting box 15. After the work is completed, the latch 25 is pulled to make the pull rod 22 slide inside the connecting plate 21, and the second spring 24 is squeezed and contracted, and the upper end of the latch 25 is pulled out from the collecting box 15. Then the collecting box 15 is pulled out from the fixed box 14, and the collected impurities are cleaned. After the cleaning is completed, the collecting box 15 is put back into the fixed box 14, and the latch 25 is pulled again and rotated, so that the latch 25 is reinserted into the collecting box 15 to restrict it.
