The inner wall of the second frame is fixedly connected to a discharge chute. Rectangular sleeves and L-shaped inserts are welded to the surfaces of the first and second frames, respectively. A cylindrical box and a vertical block are connected to the surfaces of the first and second frames, respectively. The vertical block has a circular hole. A sliding rod is slidably connected to the inner wall of the cylindrical box, and a column block is fixedly connected to the end of the sliding rod. This utility model limits the horizontal connection between the first and second frames by the insertion of the rectangular sleeves and L-shaped inserts, and limits the vertical connection by the engagement of the column block and the inner cavity of the circular hole. This allows the first and second frames to be aligned and easily fixed, achieving pre-fixation of the middle section of the coal chute to the frame, aligning the perforations of the frames, and facilitating bolt installation.

Description

Technical Field

[0001] This utility model belongs to the field of coal conveying technology, and in particular relates to a discharge trough connection structure for a curved coal drop pipe. Background Technology

[0002] Curved coal chute technology utilizes the elasticity, viscosity, plasticity, deformation level, sliding, expansion, and flowability of material particles. Based on this analysis, a mathematical model is established, combined with computer simulation technology, to transform the original coal descent process into a coal sliding process. It controls the magnitude and direction of the coal flow's kinetic energy changes during the sliding process, ensuring it slides strictly according to the optimal tangential angle and velocity. It matches the horizontal velocity of the coal stream outlet with the speed of the receiving conveyor belt, allowing the coal stream to slide smoothly onto the receiving belt. The curved coal chute technology employs a streamlined discharge chute to ensure material is output at the optimal angle, guaranteeing material collection and conveying, controlling the induced draft of the coal flow, and mitigating the impact and wear of the coal flow on the equipment.

[0003] Because the discharge chute of the coal chute is in direct contact with the material, it may be damaged due to wear after long-term use, requiring frequent disassembly, repair, or replacement. Furthermore, the connection between the middle section of the coal chute and the discharge chute is fixed with bolts. In actual installation, it is necessary to align the perforations of the middle section of the coal chute and the edge of the discharge chute. Therefore, a curved coal chute discharge chute connection structure is needed to pre-fix the middle section of the coal chute and the edge of the discharge chute, so that the perforations of the edge can be aligned and easily fixed, thereby facilitating the installation of bolts. Utility Model Content

[0021] In the following description, embodiments of the discharge chute connection structure for the curved coal chute of this invention will be described with reference to the accompanying drawings.

[0022] Example 1:

[0023] Figure 1-4 This invention illustrates a curved coal chute connection structure according to an embodiment of the present invention, comprising a first frame 1 and a second frame 2. A discharge chute 3 is fixedly connected to the inner wall of the second frame 2. Rectangular sleeve blocks 4 and L-shaped insert blocks 5 are welded to the surfaces of the first frame 1 and the second frame 2, respectively. A cylindrical box 6 and a vertical block 7 are respectively connected to the surfaces of the first frame 1 and the second frame 2. A circular hole 8 is provided in the vertical block 7. A sliding rod 9 is slidably connected to the inner wall of the cylindrical box 6. A column block 10 is fixedly connected to the end of the sliding rod 9. A rectangular opening 11 is provided at the top of the vertical block 7. The column block 10 is located within the cavity of the circular hole 8. The diameter of 10 is larger than the inner wall spacing of the rectangular opening 11. A circular plate 12 is fixedly connected to the surface of the slide rod 9. A spring 13 is fixedly connected between the circular plate 12 and the inner wall of the cylindrical box 6. A pressing block 14 is fixedly connected to the end of the slide rod 9. By setting the pressing block 14, the contact area of ​​the end of the slide rod 9 is increased, avoiding finger pain when pressing the slide rod 9 directly, thereby improving the comfort of pressing the slide rod 9. A bolt 15 is installed between the first frame 1 and the second frame 2. The middle section of the coal drop pipe 17 is fixedly connected to the inner wall of the first frame 1.

[0024] Example 2:

[0025] Figure 1-4This invention illustrates a curved coal chute connection structure according to an embodiment of the present invention, comprising a first frame 1 and a second frame 2. A discharge chute 3 is fixedly connected to the inner wall of the second frame 2. Rectangular sleeve blocks 4 and L-shaped insert blocks 5 are welded to the surfaces of the first frame 1 and the second frame 2, respectively. A cylindrical box 6 and a vertical block 7 are respectively connected to the surfaces of the first frame 1 and the second frame 2. A circular hole 8 is provided in the vertical block 7. A sliding rod 9 is slidably connected to the inner wall of the cylindrical box 6. A column block 10 is fixedly connected to the end of the sliding rod 9. A rectangular opening 11 is provided at the top of the vertical block 7. A circular plate 12 is fixedly connected to the surface of the sliding rod 9. A spring 13 is fixedly connected between the inner wall of the cylindrical box 6 and the frame 1. A bolt 15 is installed between the frame 1 and the frame 2. A washer 16 is fitted on the surface of the bolt 15. The washer 16 is an elastic washer. The setting of the washer 16 increases the friction on the surface of the bolt 15, and avoids the bolt 15 from loosening and falling out due to external vibration, thereby improving the tightness of the bolt 15 installation. The middle section 17 of the coal drop pipe is fixedly connected to the inner wall of the frame 1. The cylindrical box 6, the slide rod 9, the column block 10 and the vertical block 7 are all nickel-chromium-molybdenum alloy steel components.

[0026] Working principle: When using this utility model, the user moves the column block 10 by pressing the slide rod 9. At this time, the slide rod 9 drives the spring 13 to deform through the circular plate 12, which then lifts the discharge chute 3 and drives the second frame 2 to fit with the first frame 1. This allows the slide rod 9 to enter the inner cavity of the circular hole 8 through the rectangular opening 11. At this time, the connection between the first frame 1 and the second frame 2 is limited horizontally by the insertion of the rectangular sleeve block 4 and the L-shaped insert block 5. Then, the slide rod 9 is released, and the rebound force of the spring 13 drives the column block 10 to fit into the inner cavity of the circular hole 8 through the circular plate 12 and the slide rod 9. The engagement of the column block 10 and the inner cavity of the circular hole 8 limits the connection between the first frame 1 and the second frame 2 in the vertical direction, thereby aligning and easily fixing the first frame 1 and the second frame 2. Then, the bolt 15 is used to fix the first frame 1 and the second frame 2, realizing the pre-fixation of the middle section of the coal drop pipe and the frame of the discharge chute, so that the frame through holes can be aligned and easily fixed, thus facilitating the installation of bolts.

[0027] In summary, the curved coal chute connection structure uses a rectangular sleeve block 4 and an L-shaped insert block 5 to horizontally limit the connection between frame 1 and frame 2, and uses the engagement of the column block 10 and the inner cavity of the round hole 8 to vertically limit frame 1 and frame 2. This allows frame 1 and frame 2 to be aligned and easily fixed, thus achieving the purpose of pre-fixing the middle section of the coal chute to the frame of the discharge chute, aligning the frame through holes and easily fixing them, thereby facilitating bolt installation.
