Abstract
Description
Technical Field
[0001] This utility model relates to the field of ore material conveying technology, specifically a leveling mechanism for ore material conveying. Background Technology
[0002] Ore material is a broad concept, referring to rocks containing valuable minerals extracted from mines. Ore refers to rocks containing useful minerals and having mining value; these useful minerals can be metallic elements, non-metallic elements, or their compounds. Ore material refers to the various material forms involved in the mining and processing of these ores. The characteristics of ore material depend on the types and amounts of minerals it contains, as well as factors such as the ore's structure and texture. To ensure the uniform transport of ore material, a leveling mechanism is needed, which is typically used to evenly spread or distribute the ore material.
[0003] Traditional ore conveying methods often suffer from uneven ore distribution. Since ore is an irregularly shaped mixture, it tends to accumulate during transport, resulting in uneven ore levels in different sections. This accumulation can clog processing equipment and negatively impact processing quality, necessitating precise ore delivery. To address this issue, some ore conveying leveling mechanisms incorporate height-limiting plates above the conveyor. When the conveyor carries ore over these plates, the accumulated ore is blocked, ensuring even distribution and preventing equipment blockages and quality issues. However, this method suffers from friction and collisions as the ore passes over the height-limiting plates, which are typically single units requiring replacement and increasing maintenance costs. Therefore, this paper proposes a new leveling mechanism for ore conveying. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a leveling mechanism for conveying ore materials, thereby solving the aforementioned technical problems that not only require overall replacement but also increase maintenance costs.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a leveling mechanism for conveying ore materials, comprising:
[0008] The conveyor belt and the protective side plate set on the outside of the conveyor belt, and the feed box is added above the conveyor belt, and the height limit plate is added on the outside of the feed box, and the bottom of the height limit plate is connected to the paving plate.
[0009] A threaded screw is located on the outside of the feed box, and a drive motor is coaxially connected to the top of the threaded screw. A sliding block is sleeved on the surface of the threaded screw, and the sliding block is connected to the height limit plate.
[0010] A rotating handle is provided on the upper surface of the height limit plate, and a connecting post is installed at the bottom of the rotating handle. The connecting post extends inward through the outer wall of the height limit plate, and a return spring is sleeved on the surface of the connecting post. The end of the return spring is tightly fitted with the surface of the connecting post and the inner wall of the height limit plate, respectively. A positioning block is installed at the bottom of the connecting post, and positioning edges are added on both sides of the positioning block.
[0011] Positioning holes are provided on the upper surface of the paving board, and the shapes of the positioning holes correspond to those of the positioning blocks and positioning edges. Positioning grooves are evenly provided on the upper part of the inner wall of the positioning holes, and the shapes of the positioning grooves correspond to those of the positioning edges. The drive motor rotates the screw on the feed box, and the sliding block moves the height limit plate up and down on the feed box according to the rotation of the screw, adjusting the working height of the paving plate. When the conveyor belt carries the ore material inside the feed box outward, the paving plate blocks the ore material accumulated on the conveyor belt and spreads it evenly on the conveyor belt. When the paving plate is severely worn, pressing the rotating handle on the height limit plate lowers the connecting column, causing the positioning block to descend and compress the return spring, separating the positioning edge from the positioning groove. Then, rotating the rotating handle causes the connecting column to rotate the positioning block and positioning edge, aligning them with the positioning hole, thus separating the paving plate from the height limit plate. On the one hand, because the paving mechanism is not an integrated design, worn parts can be replaced individually, reducing maintenance costs. On the other hand, when the paving plate is connected to the height limit plate, the return spring drives the positioning block to rise through the connecting column, while the positioning edge is inserted into the positioning groove, ensuring connection stability and facilitating disassembly and assembly.
[0012] Preferably, support legs are installed on both sides of the bottom of the protective side plate, and the support legs are U-shaped, while both sides of the protective side plate are semi-circular. The support legs provide stable support for the protective side plate and its connecting structure, and at the same time, the protective side plate can prevent ore materials on the conveyor belt from falling off.
[0013] Preferably, limit grooves are provided on both sides of the inner wall of the feed box, and limit blocks are installed on both sides of the height limit plate. When the height limit plate moves up and down, the limit blocks can move up and down in the same direction along the limit grooves to avoid misalignment when the height limit plate moves up and down.
[0014] Preferably, both the limiting block and the limiting groove are T-shaped, and their positions and shapes correspond to each other. The T-shaped design of the limiting block and the limiting groove not only facilitates separation operations but also ensures the stability of the connection between the limiting block and the limiting groove during sliding, preventing separation and detachment.
[0015] Preferably, each sliding block has a side connecting plate mounted on its top, and the side connecting plate is connected to the height limiting plate. The sliding block drives the height limiting plate to move in the same direction through the side connecting plate.
[0016] Preferably, the rotating handle and connecting column are inserted into the height limit plate, and the positioning block and positioning edge are both located on the lower surface of the height limit plate. The rotating handle and connecting column can drive the positioning block and positioning edge to perform lifting and rotation operations on the height limit plate.
[0017] (III) Beneficial Effects
[0018] Compared with the prior art, the present invention provides a leveling mechanism for conveying ore materials, which has the following beneficial effects:
[0019] This ore material conveying leveling mechanism, when conveying ore material from inside the feed box to the outside via a conveyor belt, uses a leveling plate to block the ore material accumulated on the conveyor belt and evenly spread it on the belt. When the leveling plate is severely worn, pressing down on the rotating handle on the height limit plate lowers the connecting column, causing the positioning block to descend and compress the return spring, separating the positioning edge from the positioning groove. Rotating the rotating handle then causes the connecting column to rotate the positioning block and positioning edge, aligning them with the positioning hole, thus separating the leveling plate from the height limit plate. On one hand, because the leveling mechanism is not an integrated design, worn parts can be replaced individually, reducing maintenance costs. On the other hand, when the leveling plate is connected to the height limit plate, the return spring, through the connecting column, causes the positioning block to rise, while the positioning edge is inserted into the positioning groove, ensuring connection stability and facilitating disassembly and assembly.

[0025] 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 protection scope of the present utility model.
[0026] This utility model provides a technical solution: a leveling mechanism for conveying ore materials, comprising: (see details) Figure 1 The conveyor belt 1 and the protective side plate 2 are provided on the outside of the conveyor belt 1. A feed box 3 is added above the conveyor belt 1, and a height limit plate 4 is added on the outside of the feed box 3. A paving plate 5 is connected to the bottom of the height limit plate 4.
[0027] Please see Figure 2 A threaded screw 6 is located on the outside of the feed box 3, and a drive motor 7 is coaxially connected to the top of the threaded screw 6. A sliding block 8 is sleeved on the surface of the threaded screw 6, and the sliding block 8 is connected to the height limit plate 4.
[0028] Please see Figure 3 A rotating handle 12 is disposed on the upper surface of the height limit plate 4, and a connecting post 13 is installed at the bottom of the rotating handle 12. The connecting post 13 extends inward through the outer wall of the height limit plate 4, and a return spring 14 is sleeved on the surface of the connecting post 13. The end of the return spring 14 is tightly fitted with the surface of the connecting post 13 and the inner wall of the height limit plate 4, respectively. A positioning block 15 is installed at the bottom of the connecting post 13, and positioning edges 16 are added on both sides of the positioning block 15.
[0029] Please see Figure 4Positioning holes 17 are provided on the upper surface of the paving plate 5, and the shapes of positioning holes 17 correspond to those of positioning blocks 15 and positioning edges 16. Positioning grooves 18 are evenly provided on the upper part of the inner wall of positioning holes 17, and the shapes of positioning grooves 18 correspond to those of positioning edges 16. The drive motor 7 drives the threaded screw 6 to rotate on the feed box 3, and the sliding block 8 drives the height limiting plate 4 to move up and down on the feed box 3 according to the rotation of the threaded screw 6, adjusting the working height of the paving plate 5. When the conveyor belt 1 carries the ore material inside the feed box 3 outward, the paving plate 5 blocks the ore material accumulated on the conveyor belt 1, and makes the accumulated ore material evenly spread on the conveyor belt 1. When the paving plate 5 is severely worn, the rotating handle 12 is pressed down on the height limiting plate 4, the connecting column 13 drives the positioning block 15 to descend, and squeezes the return spring 14, so that the positioning edge 16 and the positioning plate 15 are aligned. After separating from the slot 18, the rotating handle 12 is rotated, and the connecting column 13 drives the positioning block 15 and the positioning edge 16 to rotate, so that the positioning block 15 and the positioning edge 16 correspond to the positioning hole 17. This allows the paving board 5 to be separated from the height limit plate 4. On the one hand, since the paving mechanism is not an integrated design, not only can worn parts be replaced individually, but maintenance costs are also reduced. On the other hand, when the paving board 5 is connected to the height limit plate 4, the return spring 14 drives the positioning block 15 to rise through the connecting column 13, while the positioning edge 16 is inserted into the interior of the positioning slot 18, which not only ensures the stability of the connection, but also facilitates disassembly and assembly.
[0030] Please see Figure 1 The bottom two sides of the protective side plate 2 are equipped with support legs, and the support legs are U-shaped. Both sides of the protective side plate 2 are semi-circular. The support legs provide stable support for the protective side plate 2 and its connecting structure, and at the same time, the protective side plate 2 can prevent the ore material on the conveyor belt 1 from falling off.
[0031] Please see Figure 2 The inner walls of the feed box 3 are provided with limiting grooves 11 on both sides, and limiting blocks 10 are installed on both sides of the height limiting plate 4. When the height limiting plate 4 moves up and down, the limiting blocks 10 can move up and down in the same direction along the limiting grooves 11 to prevent misalignment of the height limiting plate 4 during the movement. Both the limiting blocks 10 and the limiting grooves 11 are T-shaped, and their positions and shapes correspond. The T-shaped design of the limiting blocks 10 and the limiting grooves 11 not only facilitates separation operations but also ensures the stability of the connection between the limiting blocks 10 and the limiting grooves 11 during sliding, preventing separation and detachment. The top of each sliding block 8 is equipped with a side connecting plate 9, which is connected to the height limiting plate 4. The sliding block 8 drives the height limiting plate 4 to move in the same direction through the side connecting plate 9.
[0032] Please see Figure 4The rotating handle 12 and connecting column 13 are inserted into the height limit plate 4, and the positioning block 15 and positioning edge 16 are both located on the lower surface of the height limit plate 4. The rotating handle 12 and connecting column 13 can drive the positioning block 15 and positioning edge 16 to perform lifting and rotation operations on the height limit plate 4.
[0033] This solution: The drive motor 7 drives the screw 6 to rotate on the feed box 3. The sliding block 8 drives the height limit plate 4 to move up and down on the feed box 3 according to the direction of the screw 6. When the height limit plate 4 moves up and down, the limit block 10 can move up and down in the same direction along the limit groove 11 to adjust the height of the paving plate 5. When the conveyor belt 1 carries the ore material inside the feed box 3 outward, the paving plate 5 blocks the ore material accumulated on the conveyor belt 1 and makes the accumulated ore material evenly spread on the conveyor belt 1. When the paving plate 5 is severely worn, the rotating handle 12 is pressed down on the height limit plate 4. The connecting column 13 drives the positioning block 15 to descend and squeezes the return spring 14, so that the positioning edge 16 separates from the positioning groove 18. Then, the rotating handle 12 is rotated, and the connecting column 13 drives the positioning block 15 and the positioning edge 16 to rotate, so that the positioning block 15 and the positioning edge 16 correspond to the positioning hole 17, so that the paving plate 5 and the height limit plate 4 can be separated.
