Description

Technical Field

[0001] This utility model belongs to the field of conveyor technology, specifically relating to a scraper conveyor. Background Technology

[0002] A scraper conveyor is a transport device that uses a scraper chain as the traction component to transport bulk materials by the continuous movement of scrapers within a trough. It is widely used in industries such as coal mining, metallurgy, and building materials, and is especially crucial for coal transportation in underground coal mining faces. It can adapt to complex working conditions, transporting materials horizontally, inclined, or on curves. It features high conveying capacity, robust structure, and the ability to work in conjunction with other equipment. Its working principle involves a motor driving a sprocket, which in turn drives the scraper chain in a cyclical motion, thus transporting material from one end of the trough to the other.

[0003] Currently, the connection between scrapers and chains is mostly achieved by directly fastening with fixing bolts. When it is necessary to replace or adjust the position of the scraper, the disassembly process is cumbersome and requires a lot of manpower and time, making it difficult to meet the needs of rapid maintenance. Therefore, a scraper conveyor is proposed. Utility Model Content

[0025] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Example 1

[0027] like Figure 1 - Figure 5 As shown, a scraper conveyor includes a conveyor body 1, within which a chain assembly 2 is installed. The chain assembly 2 includes chains A21 and B22, which are hinged at intervals to form a ring structure. The chain assembly 2 is connected to the conveyor body 1 via sprockets. A scraper 3 is installed on the chain assembly 2, with limit blocks 6 slidably installed on both sides of the scraper 3. Extension rods 5 are symmetrically slidably installed on the scraper 3, pressing and limiting the limit blocks 6 through the extension rods 5. Strip blocks 4 are slidably installed on the scraper 3, driving the extension rods 5 to move to both sides through the strip blocks 4. The chain A21 and chain B22 are hinged at intervals to form a ring structure, enabling the chain... When the strip assembly 2 runs within the main body 1 of the conveyor, the force is more even, reducing local wear caused by uneven force, significantly reducing the probability of jamming, and ensuring the continuity of the conveying process. The limiting blocks 6 on both sides of the scraper 3 can provide precise positioning when connected to the chain assembly 2. The symmetrically arranged extension rods 5 can apply force to the limiting blocks 6 from both sides simultaneously, ensuring that the limiting blocks 6 move in unison. The strip block 4, as a driving component, can efficiently control the movement of the extension rods 5. The cooperation of the three makes the connection and separation of the scraper 3 and the chain assembly 2 convenient and labor-saving, significantly shortening the time for installation, disassembly and maintenance of the scraper 3, and improving the overall maintenance efficiency of the equipment.

[0028] The scraper 3 has a groove 31, through which the extension rod 5 and the strip block 4 are slidably connected to the scraper 3. Mounting brackets 32 are provided on both sides of the scraper 3, and through slots 33 are provided on the mounting brackets 32. A limiting block 6 is slidably positioned in the through slots 33. The groove 31 provides a sliding path for the extension rod 5 and the strip block 4, restricting their movement trajectory and preventing component jamming due to offset, thus ensuring the accuracy of the extension rod 5 and the strip block 4's movements. The mounting bracket 32 ​​not only provides a stable mounting base for the limiting block 6, enhancing the structural strength of the connection between the scraper 3 and the chain assembly 2, but its through slots 33 also provide a smooth sliding channel for the limiting block 6, reducing frictional resistance during sliding and making the limiting block 6 more flexible during extension and retraction. It also effectively prevents the limiting block 6 from loosening or falling off during operation, further improving the stability of the connection between the scraper 3 and the chain assembly 2.

[0029] One end of the extension rod 5 is equipped with a wedge block 51, and a spring 52 is installed between the wedge block 51 and the slide groove 31. The other end of the extension rod 5 is symmetrically angled. The inclined surface design of the wedge block 51 makes the contact between the strip block 4 and the extension rod 5 a surface contact, which can evenly transmit the thrust of the strip block 4 to the extension rod 5, reduce local stress, and reduce the resistance when the strip block 4 drives the extension rod 5, making the driving process more effortless. When the strip block 4 moves in the opposite direction, the spring 52 can automatically push the extension rod 5 to reset without manual intervention, simplifying the operation steps of disassembling the scraper 3 and saving manpower and time costs.

[0030] The limiting block 6 is provided with a second inclined block 61, which is parallel to the angle of the extension rod 5 and abuts against the extension rod 5. The chain A21 is provided with a mounting plate 23, which has a limiting groove. The limiting block 6 is embedded in the limiting groove. The scraper 3 is connected to the mounting plate 23 through the limiting block 6. The symmetrical angle of the other end of the extension rod 5 cooperates with the second inclined block 61 on the limiting block 6, which can efficiently convert the horizontal movement of the extension rod 5 into the vertical movement of the limiting block 6, ensuring that the limiting block 6 can be embedded in the limiting groove of the mounting plate 23, thus improving the reliability of the connection. The mounting plate 23 provides a support structure for the connection between the scraper 3 and the chain A21. The limiting groove provided on it can provide an embedding position for the limiting block 6, ensuring that the scraper 3 will not wobble laterally or longitudinally after being connected to the chain group 2.

[0031] A bolt 41 is rotatably mounted on the strip block 4, and a nut 7 is fixedly mounted in the slide groove 31. The nut 7 is threadedly connected to the bolt 41. The two ends of the strip block 4 are provided with bevels parallel to the inclined block 51. The strip block 4 abuts against the inclined block 51. The threaded connection between the bolt 41 and the nut 7 has a self-locking function. The movement distance of the strip block 4 can be controlled by rotating the bolt 41 to drive the extension rod 5.

[0032] It should be noted that the working principle of this scraper conveyor is as follows: When the scraper 3 needs to be installed, the mounting bracket 32 ​​is embedded into the mounting plate 23, and then the bolt 41 on the strip block 4 is rotated. Since the bolt 41 is threadedly connected to the nut 7 in the slide groove 31, the strip block 4 will be driven to slide in the slide groove 31 of the scraper 3; the bevels at both ends of the strip block 4 abut against the bevel block 51 on the extension rod 5. As the strip block 4 moves, it will squeeze the bevel block 51, causing the symmetrically arranged extension rod 5 to overcome the elastic force of the spring 52 and move to both sides of the scraper 3; the bevel at the other end of the extension rod 5 abuts against the bevel block on the limit block 6. The angle between the inclined block 261 and the extension rod 5 is parallel. When the extension rod 5 moves to both sides, it will squeeze the inclined block 261, causing the limiting block 6 to slide outward and extend in the through groove 33 of the mounting frame 32. At this time, the limiting block 6 is embedded in the limiting groove of the mounting plate 23 of the chain A21 in the chain assembly 2, realizing a stable connection between the scraper 3 and the chain assembly 2. Conversely, when the bolt 41 is rotated in the opposite direction, the strip block 4 moves in the opposite direction, the spring 52 returns to its original position and pushes the extension rod 5 back, releasing the compression of the limiting block 6 by the extension rod 5. The limiting block 6 can then slide back in the through groove 33, facilitating the disassembly or position adjustment of the scraper 3. When the conveyor is working, the chain assembly 2 is driven by the sprocket to move in a circular motion. The ring structure formed by the interlocking of the chain A21 and the chain B22 drives the scraper 3 to move. The scraper 3 realizes the material conveying through its structure and the upper limit connection.

[0033] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
