Description

Technical Field

[0001] This utility model relates to the field of mining belt conveyor technology, specifically a belt scraper device with automatic adjustment function. Background Technology

[0002] A mining belt conveyor is a feeding device that uses a closed conveyor belt structure. The belt speed is adjusted by a speed-regulating motor driving the drums, thereby controlling the feed rate. Its working principle is based on friction drive; material is input at the feeding end and transported by the conveyor belt to the discharge end. This equipment is suitable for conveying powdery, lumpy, or granular bulk materials and is widely used in metallurgy, mining, and coal industries.

[0003] In modern industrial production, belt conveyors are commonly used to transport solid materials. Due to issues such as material adhesion, materials may spill during belt transport. Spilled materials have become one of the technical problems that plague the production site. Traditional belt cleaning devices have low cleaning efficiency and short service life due to various reasons, which seriously affects on-site safe production. Utility Model Content

[0012] Compared with the prior art, the present invention provides a belt scraper with automatic adjustment function, which has the following advantages:

[0013] 1. This belt scraper with automatic adjustment function, through the set lever mechanism, the scraper plate is made of soft material and is fixed by steel plate, so there will be no accident of scratching the conveyor belt, thus ensuring inherent safety; because the scraper plate is in close contact with the moving parts (belt) of the belt conveyor, the cleaning efficiency is high; it can be automatically adjusted, reducing the amount of manual adjustment and reducing labor intensity.

[0014] 2. This belt scraper device with automatic adjustment function uses waste belts as scraper plates through an adjustment mechanism, which has a wide range of material sources. After the scraper plates are worn, they can be repeatedly used through adjustment, resulting in a long service life and saving a lot of costs. Attached Figure Description

[0019] Example 1

[0020] Combination Figures 1 to 3A belt scraper with automatic adjustment function includes a steel pipe 1, and an adjustment mechanism 2 and a lever mechanism 3 are respectively provided on the outer wall of the steel pipe 1.

[0021] The lever mechanism 3 includes a first positioning block 38, which is movably connected to the outer wall of the steel pipe 1. A bolt 2 301 is provided inside the first positioning block 38, and a nut 2 302 is threadedly connected to the outer wall of the bolt 2 301. A second positioning block 39 is movably connected to the outer wall of the steel pipe 1. A support plate 2 37 is fixedly connected to the right side of the first positioning block 38. A support plate 1 33 is fixedly connected to the inner side of the support plate 2 37. A fixing rod 32 is rotatably connected inside the support plate 1 33.

[0022] Mounting plates 31 are fixedly connected to both ends of the fixed rod 32. A fixed shaft 34 is fixedly connected inside the support plate 33. A hook 35 is fixedly connected to the outer wall of the fixed shaft 34. A counterweight 36 is movably connected to the outer wall of the hook 35.

[0023] Both the first positioning block 38 and the second positioning block 39 have round holes inside, and the bolt 301 passes through the round holes. With the cooperation of the first positioning block 38 and the second positioning block 39, the support plate 37 can be installed and connected, which is convenient for operation and use.

[0024] Example 2

[0025] See Figures 1 to 3 Furthermore, based on Embodiment 1, the adjustment mechanism 2 includes a steel plate 21, which is fixedly connected to the outer wall of the steel pipe 1. A bolt 22 is provided inside the steel plate 21, and a nut 23 is threadedly connected to the right end of the bolt 22. A scraper 24 is provided on the right side of the steel plate 21. If the scraper 24 is worn, it can be adjusted up and down to fit the belt.

[0026] The scraper 24 has an elongated opening inside, through which bolt 22 passes. Bolt 22 can be adjusted within the elongated opening.

[0027] Nut 23 is in contact with scraper 24 on the left side. A through hole is provided inside the steel plate 21. Bolt 22 passes through the through hole, so that bolt 22 can pass through the through hole and screw nut 23 into its outer wall.

[0028] In actual operation, when this device is used, it is first installed on the outside of the mining belt conveyor through the inner mounting plate 31. Under the weight of the counterweight 36, the scraper 24 can be in close contact with the belt of the mining belt conveyor, thereby scraping off the material adhering to the belt of the mining belt conveyor. At the same time, it ensures that the scraper 24 can be in close contact with the belt and can be automatically adjusted, resulting in high cleaning efficiency and facilitating safe on-site work.

[0029] During prolonged use, the scraper 24 will wear out. At this time, the nut 23 can be rotated to remove the pressure of the scraper 24. The position of the scraper 24 can then be adjusted through the elongated opening in the scraper 24, allowing the scraper 24 to better fit the belt. After the scraper wears out, it can be adjusted and reused repeatedly, resulting in a long service life and significant cost savings.
