Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically to a grate for a single-toothed roller crusher. Background Technology

[0002] A single-toothed roll crusher is a device that uses a single rotating toothed roll in conjunction with fixed components (such as grate plates and jaw plates) to crush materials through compression, shearing, splitting, and other actions. It is widely used in the metallurgical, mining, building materials, and chemical industries, and is especially common in the crushing of hard materials in sintered ore, coal, and ores.

[0003] Existing single-tooth roller crushers can strictly control the output particle size of the grate, avoiding the mixing of excessively coarse or fine materials, ensuring uniform particle size of the crushed product, and meeting the strict requirements of subsequent production for material particle size. However, the strength of the connection parts is insufficient. Under high-frequency impact loads, the wear-resistant working parts and the mounting base are prone to relative displacement or loosening, or even falling off. The existing technology uses "wedge self-locking fit plus positioning pin" to replace the traditional bolt connection. At the same time, the cylindrical positioning pin restricts horizontal displacement and reduces the force on the bolt. However, the long-term friction between the positioning pin and the pin hole leads to pin hole wear, which reduces the positioning accuracy and weakens the horizontal displacement restriction ability. After the pin hole is worn, it cannot be repaired by tapping like the bolt hole, which will lead to the scrapping of the entire mounting base or grate in the existing technology. Utility Model Content

[0033] like Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of this utility model is provided: a single-toothed roller crusher grate, including a base 1, a frame 2 fixedly connected to the left side of the top wall of the base 1, a single-toothed roller shaft 3 provided on the top of the frame 2, a plurality of crushing plates 4 equidistantly arranged on the inner wall of the frame 2, the outer edge of the crushing plates 4 having a wear-resistant coating, a fixing mechanism 5 provided inside the frame 2 for fixing the crushing plates 4, and a support disassembly mechanism 6 installed on the top wall of the base 1 for supporting the single-toothed roller shaft 3 for easy disassembly;

[0034] The fixing mechanism 5 includes a T-shaped block 501, which is fixedly connected to the front and rear sides of the outer wall of the crushing plate 4. The inner wall of the frame 2 is provided with multiple sliding grooves 502 at equal intervals. The sliding grooves 502 are slidably connected to the T-shaped block 501. The T-shaped block 501 slides into the sliding groove 502 of the frame 2. The top wall of the T-shaped block 501 is threaded with bolts 504 on both the left and right sides. The outer wall of the bolts 504 is provided with springs 505. The inner bottom wall of the sliding groove 502 is provided with threaded holes 503 on both the left and right sides. The bolts 504 are passed through the T-shaped block 501 and screwed into the threaded holes 503 in the sliding groove 502. The bolts 504 compress the springs 505 to achieve a stable fixation of the crushing plate 4. The frame 2 is provided with an auxiliary component 506.

[0035] The auxiliary component 506 includes a circular groove 5061, which is formed on the front and rear sides of the outer wall of the T-block 501 and the frame 2. The outer wall of the T-block 501 is provided with a pin 5062, which engages with the circular groove 5061. A spring 505 is provided on the top of the T-block 501. The T-block 501 is threadedly connected to the threaded hole 503 by a bolt 504. The pin 5062 is inserted through the frame 2 into the circular groove 5061 on the outer wall of the T-block 501 to further limit the displacement.

[0036] Specifically, the T-block 501 is inserted into the groove 502 of the frame 2 to initially position the crushing plate 4. Then, the bolt 504 is passed through the T-block 501 and screwed into the threaded hole 503 in the groove 502. The bolt 504 applies pressure to the spring 505 to ensure the stable fixing of the crushing plate 4. Subsequently, the pin 5061 is passed through the frame 2 and inserted into the outer wall circular groove 5062 of the T-block 501 to further limit its displacement. This design can effectively resist high-frequency impact and vibration during the crushing process and prevent the crushing plate 4 from loosening or shifting. In addition, this installation method is easy for a single person to operate and significantly reduces the time required to install or replace the crushing plate 4, thereby improving maintenance efficiency.

[0037] like Figure 2 , Figure 3 and Figure 5 As shown, the support disassembly mechanism 6 includes a column 601, which is fixedly connected to the left and right sides of the top wall of the base 1. A support seat 602 is slidably connected to the inner wall of the column 601. A threaded rod 603 is rotatably connected to the inner bottom wall of the column 601. The threaded rod 603 is threadedly connected to the inner wall of the support seat 602. The threaded rod 603 drives the support seat 602 to rise inside the column 601. The rising support seat 602 supports the single toothed roller shaft 3 to achieve support. A drive assembly 604 is installed on the top wall of the base 1.

[0038] The drive assembly 604 includes a dual-head motor 6041, which is fixedly connected to the middle of the rear side of the top wall of the base 1. A rotating shaft 6042 is fixedly connected to the output end of the dual-head motor 6041, driving the rotating shaft 6042 to rotate. A universal joint 6043 is fixedly connected to the end of the rotating shaft 6042, and a rotating shaft 6044 is fixedly connected to the end of the universal joint 6043. The rotation of the rotating shaft 6042 drives the rotating shaft 6044 to rotate via the universal joint 6043. A helical gear 6045 is fixedly connected to the front end of the outer wall of the rotating shaft 6044, driving the rotating shaft 6044 to rotate. Helical gear 6045 rotates, and helical gear 6046 is fixedly connected to the bottom end of threaded rod 603. Helical gear 6046 meshes with helical gear 6045. Helical gear 6045 drives helical gear 6046 to rotate, and helical gear 6046 drives threaded rod 603 to rotate. Rotating shaft 6044 passes through the lower middle part of the rear side of the outer wall of column 601. Helical gear 6046 is rotatably connected to the inner bottom wall of column 601. Single toothed roller shaft 3 is rotatably connected to the top wall of support base 602. Support base 602 adopts a U-shaped design, and the U-shaped design of support base 602 can fit the single toothed roller shaft 3.

[0039] Specifically, during the disassembly of the single-tooth roller shaft 3, the dual-head motor 6041 should be started first. The dual-head motor 6041 drives the first rotating shaft 6042 to rotate. The rotation of the first rotating shaft 6042 is transmitted to the second rotating shaft 6044 through the universal joint 6043, which in turn drives the first helical gear 6045 to rotate. The first helical gear 6045 meshes with the second helical gear 6046, causing the second helical gear 6046 to rotate, which in turn drives the threaded rod 603 to rotate. The rotation of the threaded rod 603 causes the support seat 602 to rise along the inside of the column 601. After the support seat 602 rises, it can support the single-tooth roller shaft 3, so as to facilitate the disassembly operation from the frame 2.

[0040] like Figure 1 , Figure 2 and Figure 3As shown, a fixing block 7 is fixedly connected to the right side of the top wall of the base 1. A drive motor 8 is fixedly connected to the top wall of the fixing block 7. The fixing block 7 is used to fix the drive motor 8 to the base 1. A connecting shaft 9 is fixedly connected to the output end of the drive motor 8. The drive motor 8 drives the connecting shaft 9 to rotate, and the connecting shaft 9 drives the single toothed roller shaft 3 to rotate. The single toothed roller shaft 3 is located inside the connecting shaft 9. The connecting shaft 9 drives the single toothed roller shaft 3 to rotate. A square block 11 is fixedly connected to the right end of the outer wall of the single toothed roller shaft 3. The left side of the top wall of the connecting shaft 9... A square groove 10 is provided on the side, which engages with a block 11. The block 11 and the square groove 10 are engaged and connected, which can transmit power to the single toothed roller shaft 3 and prevent slippage. A limiting groove 12 is provided on the left side of the top wall of the connecting shaft 9. A round block 13 is fixedly connected to the right end of the outer wall of the single toothed roller shaft 3. The limiting groove 12 engages with the round block 13. The round block 13 is engaged in the limiting groove 12 to prevent radial displacement or separation due to vibration and impact during operation, thus enhancing the stability and reliability of the connection.

[0041] Specifically, the fixing block 7 is used to fix the drive motor 8 on the base 1. The drive motor 8 drives the connecting shaft 9 to rotate, and the connecting shaft 9 drives the single toothed roller shaft 3 to rotate. The square block 11 and the square groove 10 are engaged and connected, which can transmit power to the single toothed roller shaft 3 and avoid slippage. The round block 13 is inserted into the limiting groove 12 to prevent radial displacement or separation due to vibration and impact during operation, thus enhancing the stability and reliability of the connection.

[0042] Working principle: The T-blocks 501 at the front and rear of the crushing plate 4 are slid into the slide grooves 502 of the frame 2 to initially position the crushing plate 4. The bolts 504 are passed through the T-blocks 501 and screwed into the threaded holes 503 in the slide grooves 502. The bolts 504 compress the springs 505 to securely fix the crushing plate 4. Then, the pins 5062 are passed through the frame 2 and inserted into the circular grooves 5061 on the outer wall of the T-blocks 501 to further restrict displacement. This can effectively resist high-frequency impacts and vibrations during crushing, prevent the crushing plate 4 from loosening or shifting, and facilitate the installation or replacement of the crushing plate 4 by a single person, greatly shortening maintenance time.

[0043] When it is necessary to disassemble the single-tooth roller shaft 3, start the dual-head motor 6041. The dual-head motor 6041 drives the first rotating shaft 6042 to rotate. The rotation of the first rotating shaft 6042 drives the second rotating shaft 6044 to rotate through the universal joint 6043. The second rotating shaft 6044 drives the first helical gear 6045 to rotate. The first helical gear 6045 drives the second helical gear 6046 to rotate. The second helical gear 6046 drives the threaded rod 603 to rotate. The threaded rod 603 drives the support seat 602 to rise inside the column 601. The rising support seat 602 supports the single-tooth roller shaft 3, making it easy to disassemble from the frame 2.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it.
