Description

Technical Field

[0001] This utility model relates to the field of conveying equipment, specifically a chain scraper conveyor. Background Technology

[0002] Chain scraper conveyors use chains with scrapers to pull materials in enclosed troughs, enabling horizontal, inclined, or vertical conveying. As a key hub in modern industrial automated production lines, they have become an indispensable basic equipment in many fields such as coal, cement, grain, and chemicals, efficiently connecting various production links and ensuring the continuous and stable operation of bulk material handling systems.

[0003] Due to the stickiness of some materials and the impact and splashing during feeding, material residue is prone to accumulate at the top of the chain scraper conveyor. The residual material will lead to a decrease in the conveying capacity of the equipment and an increase in energy consumption. In addition, the accumulated material may suddenly fall off, causing local blockage or instantaneous overload. Therefore, a chain scraper conveyor is proposed to address the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, material residue is prone to accumulate at the top of the inside of chain scraper conveyors. This residue can lead to reduced conveying capacity and increased energy consumption. This invention proposes a chain scraper conveyor.

A striking mechanism is provided inside the machine body, and the scraper is used in conjunction with the striking mechanism. The striking mechanism includes two threaded rods rotatably connected inside the machine body. Each of the two threaded rods has a movable block threadedly fitted on its surface. A striking plate is rotatably connected to the opposite side of each of the two movable blocks. Torsion springs are fixedly connected to the surfaces of the two movable blocks respectively. One end of each of the two torsion springs is fixedly connected to the two sides of the striking plate respectively. A positioning component is provided inside the machine body, and the positioning component works in conjunction with the threaded rods.

[0006] Preferably, the interior of the machine body is provided with a sliding groove, and a slider is fixedly connected to the surface of the movable block, with the surface of the slider slidably connected to the inner cavity of the sliding groove.

[0007] Preferably, one end of each of the two threaded rods passes through the machine body and is rotatably connected to the inner cavity of the machine body. One end of one of the threaded rods is fixedly fitted with a first gear, and one end of the other threaded rod is fixedly fitted with a second gear.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail. This application discloses a chain scraper conveyor. (Refer to...) Figure 4 and Figure 6 A chain scraper machine includes a machine body 1. Two sets of sprockets 101 are rotatably connected inside the machine body 1. Each set of sprockets 101 has two sprockets 101. The surfaces of the two sprockets 101 are jointly driven by a chain 102. A scraper 103 is fixedly connected to the opposite side of the two chains 102. A striking mechanism 2 is provided inside the machine body 1. The scraper 103 is used in conjunction with the striking mechanism 2. The striking mechanism 2 includes two threaded rods 201 rotatably connected inside the body 1. Each of the two threaded rods 201 has a movable block 202 threadedly fitted on its surface. The two movable blocks 202 are rotatably connected to a striking plate 203 on their opposite sides. Torsion springs 204 are fixedly connected to the surfaces of the two movable blocks 202 respectively. One end of each torsion spring 204 is fixedly connected to both sides of the striking plate 203. A positioning component 3 is provided inside the body 1. The positioning component 3 works in conjunction with the threaded rods 201. When material accumulates at the top inside the machine body 1, the threaded rod 201 is rotated. The threaded rod 201 drives the striking plate 203 to move via the moving block 202, so that the striking plate 203 is adjusted to the material accumulation area. Then, the scraper 103 is driven to rotate via the chain 102. When the scraper 103 moves to contact the striking plate 203, the scraper 103 pushes one end of the striking plate 203, causing the other end of the striking plate 203 to separate from the top inside the machine body 1. As the scraper 103 continues to rotate, the scraper 103 separates from the striking plate 203. At this time, the torsion spring 204 twists the striking plate 203, causing the other end of the striking plate 203 to strike the top inside the machine body 1 and generate vibration. Thus, the striking of the striking plate 203 shakes off the fine powder and sticky materials adhering to the top, avoiding the situation where the material continues to accumulate and form a blockage that affects the conveying.

[0018] Reference Figure 1 and Figure 4 The machine body 1 has a sliding groove 205 inside, and a slider 206 is fixedly connected to the surface of the moving block 202. The surface of the slider 206 is slidably connected to the inner cavity of the sliding groove 205. When the threaded rod 201 is rotated, the slider 206 and the sliding groove 205 stabilize the moving block 202, allowing it to slide on the surface of the threaded rod 201, thus preventing the moving block 202 from rotating with the threaded rod 201.

[0019] Reference Figure 2 and Figure 6 One end of each of the two threaded rods 201 passes through the body 1 and is rotatably connected to the inner cavity of the body 1. One end of one threaded rod 201 is fixedly fitted with a first gear 207, and one end of the other threaded rod 201 is fixedly fitted with a second gear 208. The surfaces of the first gear 207 and the second gear 208 are jointly fitted with a synchronous toothed belt 209. When the threaded rods 201 are rotated, one threaded rod 201 drives the first gear 207 to rotate, and the first gear 207 drives the second gear 208 to rotate through the synchronous toothed belt 209, so that the second gear 208 drives the other threaded rod 201 to rotate synchronously. Thus, rotating one threaded rod 201 drives the two moving blocks 202 to move synchronously, avoiding the situation where the striking plate 203 tilts to one side.

[0020] Reference Figure 4 and Figure 5 The machine body 1 has a limiting groove 210 inside, and a limiting block 211 is fixedly sleeved on the surface of another threaded rod 201. The surface of the limiting block 211 is slidably connected to the inner cavity of the limiting groove 210. When one threaded rod 201 drives the other threaded rod 201 to rotate, the position of the other threaded rod 201 is ensured by the stability of the limiting groove 210 and the limiting block 211, thus preventing the other threaded rod 201 from separating from the surface of the machine body 1.

[0021] Reference Figure 2 and Figure 3 The positioning component 3 includes an opening 301 inside the body 1. Several arc-shaped blocks 302 are fixedly connected inside the opening 301. Several sleeve rods 303 are fixedly connected to the surface of one threaded rod 201. An inner rod 304 is slidably connected inside the sleeve rod 303. One end of the inner rod 304 passes through the sleeve rod 303 and is slidably connected to the inner cavity of the sleeve rod 303. The inner rod 304 cooperates with the arc-shaped blocks 302. A spring 305 is installed inside the sleeve rod 303. One end of the spring 305 is connected to the sleeve rod 302. The inner wall of the 3 is fixedly connected, and the other end of the spring 305 is fixedly connected to the other end of the inner rod 304. When the threaded rod 201 is rotated, the threaded rod 201 drives the inner rod 304 to rotate through the sleeve rod 303. When the inner rod 304 rotates to the concave surface of the arc block 302, the spring 305 pushes the inner rod 304, so that the inner rod 304 inserts into the concave surface of the arc block 302, thereby positioning the threaded rod 201 and preventing the threaded rod 201 from being mis-rotated due to vibration or other factors, which would lead to the position of the striking plate 203 being offset.

[0022] Reference Figure 2 and Figure 3 The sleeve rod 303 is fixedly connected to a stop 306, and the other end of the inner rod 304 is fixedly connected to a protrusion 307. The stop 306 and the protrusion 307 work together. When the spring 305 pushes the inner rod 304, the position of the inner rod 304 is ensured by the stability of the stop 306 and the protrusion 307, and the inner rod 304 is prevented from disengaging from the inner cavity of the sleeve rod 303.

[0023] Working principle: When material accumulates at the top inside the machine body 1, rotating one of the threaded rods 201 drives the first gear 207 to rotate. The first gear 207, through the synchronous toothed belt 209, drives the second gear 208 to rotate, which in turn drives the other threaded rod 201 to rotate. This allows the two moving blocks 202 to synchronously drive the striking plate 203 to move, preventing one side of the striking plate 203 from tilting. After the striking plate 203 is moved to the appropriate position, the chain 102 drives the scraper 103 to rotate. When the scraper 103 rotates to contact the striking plate 203, the scraper 103 pushes one end of the striking plate 203, causing the other end of the striking plate 203 to separate from the top inside the machine body 1. As the scraper 103 continues to rotate, the scraper 103 separates from the striking plate 203. At this time, the torsion spring 204 twists the striking plate 203, causing the other end of the striking plate 203 to strike the top inside the machine body 1 and thus generate vibration. In this way, the striking of the striking plate 203 shakes off the fine powder and sticky materials adhering to the top, avoiding the situation where materials continue to accumulate and form blockages that affect the conveying.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
