[0002] Scraper conveyor is a continuous conveying equipment, mainly used for horizontal or slightly inclined transportation. It can transport various loose, powdered, block and sheet materials to designated locations. It is widely used in coal mines, mining, metallurgy, chemical industry, building materials and other industries. It can be used to transport coal, ore, powdered materials, sintered ore, etc.

[0003] After searching, the application number CN202323391312.3 discloses a scraper conveyor, including a motor housing and a leveling mechanism. When the conveying angle of the scraper conveyor needs to be adjusted, the hydraulic rod is driven to make the output end of the hydraulic rod pull the sliding block toward the back. At this time, the sliding block slides stably backward under the joint action of the limit bar and the limit slide bar, and the transmission arm is lifted to change the angle of the scraper conveyor, thereby avoiding the problem of material sliding off the top of the scraper in large quantities when conveying at an inclined angle.

[0004] Existing scraper conveyors use a leveling mechanism to change the inclination angle to reduce material slippage during transportation. The inclination of the entire scraper conveyor needs to be controlled, and there are high requirements for the load-bearing performance and driving power of the leveling mechanism. The conveyed materials are generally in the form of scattered powders, blocks, and sheets. By only changing the conveying angle, the material slides from the top of the scraper under the action of gravity, causing material spillage, which affects the conveying volume and has an adverse effect on the conveying environment.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model will be further described in detail in conjunction with the accompanying drawings.

[0024] Please refer to Figure 1 - Figure 5 , which is an anti-slip scraper device for a scraper conveyor provided by the present utility model, including a scraper conveyor 1, a driving device 2 and several groups of scraper mechanisms 3.

[0025] Among them, please refer to Figure 1 , the driving device 2 is installed on the side wall of the scraper conveyor 1, and several groups of scraper mechanisms 3 are spaced apart and distributed in the inner cavity of the scraper conveyor 1. The driving device 2 drives several groups of scraper mechanisms 3 to move to convey materials.

[0026] It can be understood that the driving device 2 includes a driving motor and two groups of roller shafts. The roller shafts are rotatably connected to the inner wall of the scraper conveyor 1. An outer belt is drivingly connected to the two groups of roller shafts. Several groups of scraper mechanisms 3 are spaced apart and arranged on the outer wall of the belt to jointly convey materials with the belt.

[0027] Please refer to Figures 2 to 5 , the scraper mechanism 3 includes a lower scraper 31. The lower end of the lower scraper 31 is fixedly connected to the outer wall of the belt. An upper scraper 32 is slidably connected to the top of the lower scraper 31. An anti-slip plate 33 is hingedly connected to one end of the upper scraper 32 away from the lower scraper 31.

[0028] Specifically, the lower scraper 31 includes a first plate body 311, a slide groove 312 is provided on the top of the first plate body 311, and connecting ropes 313 are fixedly connected to the two ends of the bottom of the slide groove 312. The upper scraper 32 includes a sliding plate 321, the lower end of the sliding plate 321 is slidably connected to the inside of the slide groove 312, and an extension plate 325 is fixedly connected to the upper end of the sliding plate 321. A limiting groove 324 is provided on the side of the extension plate 325 away from the sliding plate 321, and a receiving groove 324 is provided on the upper end surface of the extension plate 325. 23. The anti-slip plate 33 includes a second plate body 331. The lower end of the second plate body 331 is fixedly connected to a limiting column 332. The limiting column 332 is rotatably connected in the limiting groove 324. The outer wall of the limiting column 332 is provided with a plurality of anti-slip grooves 333. The second plate body 331 is rotatably connected to the extension plate 325 through the limiting column 332 and the limiting groove 324. When the angle between the second plate body 331 and the extension plate 325 is 0, the second plate body 331 is received in the accommodating groove 323.

[0029] At the same time, a through hole 322 is opened in the sliding plate 321 and the extension plate 325. One end of the through hole 322 is opened at the bottom of the sliding plate 321, and the other end of the through hole 322 is opened at the upper end surface of the extension plate 325 near the top. The connecting rope 313 passes through the through hole 322 from the bottom of the sliding plate 321, and is fixedly connected to the lower end of the side wall of the second plate body 331 after passing through the upper end surface of the extension plate 325.

[0030] It can be understood that the second plate body 331 is rotatably connected to the top of the extension plate 325. When conveying materials, the materials slide along the upper end surface of the first plate body 311 to the direction of the receiving groove 323 due to the action of gravity. The materials push the second plate body 331 to make the sliding plate 321 slide outward along the inner wall of the slide groove 312, thereby extending the overall height of the scraper to prevent the materials from sliding off the top of the scraper. At the same time, the sliding plate 321 drives the second plate body 331 to move upward through the extension plate 325, so that the connecting rope 313 is tightened. The connecting rope 313 guides the second plate body 331 to rotate toward the direction of the receiving groove 323 through the through hole 322. The second plate body 331 forms a barrier on the top of the extension plate 325, further preventing the materials from sliding through the top of the scraper.

[0031] It should be noted that the limiting post 332 is rotatably connected to the limiting slot 324 , and a blocking member is provided on the inner wall of the limiting slot 324 to prevent the limiting post 332 from being separated from the limiting slot 324 without affecting the rotation of the limiting post 332 .

[0032] It should also be noted that the width of the sliding plate 321 is equal to the width of the first plate body 311, and the width of the first plate body 311 is equal to the inner wall of the scraper conveyor 1, that is, the slide groove 312 runs through the side walls of the first plate body 311 on both sides to prevent materials from leaking from the gap between the two sides of the sliding plate 321 and the inner wall of the scraper conveyor 1 during transportation.

[0033] Principle: The material to be conveyed is placed on the upper end surface of the conveyor belt. The conveyor belt conveys the material to the other end at a certain inclination angle. The material slides along the upper end surface of the first plate body 311 under the action of gravity. When the material slides to the top of the upper end surface of the sliding plate 321, it pushes the second plate body 331 so that the through hole 322 slides upward along the inner wall of the chute 312, thereby appropriately extending the height of the scraper according to the amount of the material. At the same time, the sliding plate 321 drives the second plate body 331 to move upward through the extension plate 325, and the connecting rope 313 fixedly connected to one end of the second plate body 331 is tightened, so that the second plate body 331 rotates toward the side close to the receiving groove 323. The second plate body 331 blocks the material on the top of the extension plate 325, further preventing the material from sliding off the top of the scraper during the conveying process and causing environmental pollution.

[0034] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
