Description

Technical Field

[0001] This utility model relates to the field of asphalt concrete production technology, specifically to an anti-clogging asphalt concrete powder storage hopper. Background Technology

[0002] Asphalt concrete powder typically refers to a fine-particle material used in asphalt concrete mixes, primarily composed of mineral powder, stone powder, and other materials. These powders effectively fill the voids in asphalt concrete, enhancing its performance and ensuring pavement quality and durability. Mineral powder is a fine-particle material obtained by finely grinding aggregates (such as granite and limestone); stone powder is typically produced during the crushing process. Their small particle size allows them to act as fillers in asphalt concrete.

[0003] For example, a clog-resistant asphalt concrete powder storage hopper, as disclosed in announcement number CN220115289U, includes a hopper body with supporting legs at the bottom and a motor box at the top. A drive motor is housed inside the motor box, and a rotating shaft extending into the hopper body is located at the output shaft of the drive motor. A stirring blade is mounted on the outer side of the rotating shaft. This clog-resistant asphalt concrete powder storage hopper, through the installation of a fixing component and an anti-clogging component, extends the rotating rod into the rectangular box. Under the tension of a spring, a stop block moves, fixing the rotating rod with a locking rod. The spiral stirring blades thus stir the material, preventing clogging during discharge. Furthermore, the rotating scraper cleans the inner wall of the hopper body, facilitating user operation and achieving the purpose of preventing clogging during discharge.

[0004] The aforementioned patent proposes that the spiral stirring blades can stir the material and prevent blockage during feeding. Secondly, the scraper can scrape the inner wall of the storage hopper when it rotates. However, in actual use, when the scraper rotates, the contact force is too large, which will damage the inner wall of the storage hopper, resulting in wear and uneven scraping, which may affect the flowability of the powder.

[0021] 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.

[0022] Example 1: Please refer to Figures 1-4A clog-resistant asphalt concrete powder storage hopper includes a storage hopper structure 1. The storage hopper structure 1 includes a bottom support 11 and a discharge hopper 19 installed inside the top of the bottom support 11. An internal frame 18 is installed inside the bottom support 11. The internal frame 18 is located on both sides of the discharge port of the discharge hopper 19. A main rotating shaft 14 is installed at both ends between the internal frames 18. An inner rotating shaft 15 is movably installed between the internal frames 18. A conveyor belt 13 is installed on the outer surface of the main rotating shaft 14 and the inner rotating shaft 15. An installation component 17 is installed at the lower end of the discharge hopper 19. A drive component 16 is installed between the outer surface of the inner rotating shaft 15 and one end of the installation component 17. A transport motor 12 is installed on the outer surface of the internal frame 18.

[0023] Mounting component 17 includes a connecting shaft 174 movably mounted inside the lower end of the discharge hopper 19. An outer ring 175 is mounted on the outer surface of the connecting shaft 174, and bent push rods 176 are symmetrically mounted on the outer surface of the outer ring 175.

[0024] An L-shaped bracket 181 is installed at the top of the built-in frame 18, a cylinder 183 is installed between the L-shaped brackets 181, and a fixed shaft 182 is installed between the L-shaped brackets 181 and the cylinder 183.

[0025] The moving end of cylinder 183 is equipped with the top side of bucket seal plate 184. Bucket seal plate 184 is installed inside the lower end of discharge hopper 19. After rotation, the bent push rod 176 will be above bucket seal plate 184. The width of bucket seal plate 184 is greater than the width of discharge port of discharge hopper 19.

[0026] The drive component 16 includes an I-shaped cylinder A161 and a drive gear 162 installed inside the I-shaped cylinder A161. Connecting bolts 166 are installed on both sides of the I-shaped cylinder A161. An I-shaped cylinder B164 is provided at the upper end of the I-shaped cylinder A161. A driven gear 165 is installed on the outer surface of the I-shaped cylinder B164. A gear chain 163 is installed on the outer surfaces of the drive gear 162 and the driven gear 165. The I-shaped cylinder A161 is fixedly installed on one end of the inner rotating shaft 15 by the connecting bolts 166.

[0027] A mounting shaft 171 is movably mounted on one end of the connecting shaft 174. An upper bending strip 172 is mounted on the top end of the mounting shaft 171. A fixing bolt 173 is threaded on the outer side of the upper bending strip 172. The mounting component 17 is fixed to the lower end of the discharge hopper 19 by the fixing bolt 173. The I-shaped cylinder B164 is movably mounted on one end of the connecting shaft 174.

[0028] In this embodiment: the cylinder 183 extends, pushing the hopper seal plate 184 towards one end of the discharge port of the discharge hopper 19, thus blocking the inside of the discharge port of the discharge hopper 19. The asphalt concrete powder is inside the discharge hopper 19. When the powder is being removed, the cylinder 183 retracts, the hopper seal plate 184 returns to its original position, and the powder inside the discharge hopper 19 is discharged to the top of the conveyor belt 13. The conveyor motor 12 operates, driving the main shaft 14 to rotate, causing the conveyor belt 13 to move on the outer surfaces of the inner shaft 15 and the main shaft 14, thus moving the powder. 5. During the rotation, the I-shaped cylinder A161 is driven to rotate. When the drive gear 162 installed inside the I-shaped cylinder A161 rotates, it will pull the toothed chain 163 to move. Since the upper end of the toothed chain 163 meshes with the outer surface of the driven gear 165, the toothed chain 163 can drive the driven gear 165 and the I-shaped cylinder B164 to rotate during the movement. The I-shaped cylinder B164 drives the connecting shaft 174 to rotate together, and drives the bent push rod 176 to rotate through the outer ring 175, so as to clear the inside of the discharge port of the discharge hopper 19 and prevent the powder from clogging the inside of the discharge port of the discharge hopper 19.

[0029] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 2-4 The inside of the curved push rod 176 is equipped with an inner support rod 177, and a connecting steel wire 178 is installed between the curved push rods 176. The inner support rod 177 supports the curved push rod 176.

[0030] In this embodiment: During the movement of the conveyor belt 13, the driving component 16 drives the connecting shaft 174 to operate synchronously, which ensures that the discharge hopper 19 discharges material smoothly while the conveyor belt 13 moves the powder together, avoiding the accumulation of powder that affects the discharge effect of the discharge hopper 19. The inner support rod 177 installed inside the curved push rod 176 supports it and prevents the curved push rod 176 from collapsing when powder accumulates inside the discharge hopper 19. The two sets of curved push rods 176 are connected by a connecting steel wire 178 to prevent the curved push rod 176 from being squeezed and bending to both sides of the outer connecting ring 175, which would affect the smooth flow of powder by the curved push rod 176. At the same time, the curved push rod 176, the inner support rod 177 and the connecting steel wire 178 reduce the space occupied inside the discharge hopper 19.
