Abstract
Description
Technical Field
[0001] This utility model relates to the field of asphalt production technology, and in particular to a cold silo for asphalt production. Background Technology
[0002] During asphalt production, hot asphalt fluid needs to be heated and mixed with cold aggregate. Before mixing, the cold aggregate is placed in a cold aggregate silo. When needed, the cold aggregate is fed into the mixing equipment from the cold aggregate silo. The cold aggregate silo is convenient for storage and retrieval, and can properly preserve the cold asphalt aggregate and prevent it from getting damp.
[0003] Because some materials used in asphalt production have a certain degree of adhesion, when materials need to be discharged from the cold aggregate bin, some materials in the cold aggregate bin will accumulate at the bottom of the cold aggregate bin, forming an arch and squeezing each other. This causes material to accumulate inside the cold aggregate bin and block the discharge port of the cold aggregate bin, affecting the normal feeding of the mixing equipment. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a cold silo for asphalt production, which solves the problem of material accumulation inside the cold silo affecting the normal feeding of the mixing equipment.
[0005] According to an embodiment of this utility model, a cold silo for asphalt production includes a frame and a silo body mounted on the frame. The silo body is provided with a rotatable main shaft and a drive motor connected to the main shaft. A sleeve is fitted on the main shaft, and the sleeve is provided with anti-bridging blades. When the drive motor drives the main shaft to rotate, the sleeve rotates synchronously and can slide along the axial direction of the main shaft. The silo body is also provided with a first mounting seat and a second mounting seat, which are located at opposite ends of the main shaft. The side of the first mounting seat near the sleeve is provided with a spherical head, and the sleeve is provided with a groove to accommodate the spherical head. A spring is also fitted on the main shaft, and the opposite ends of the spring in the extension direction abut against the sleeve and the second mounting seat, respectively.
[0006] Furthermore, the output end of the drive motor is provided with a driving gear, and one end of the main shaft is provided with a driven gear, which meshes with the driving gear.
[0007] Furthermore, the main shaft is provided with a limiting pin, the axial direction of which is consistent with the radial direction of the main shaft, and the sleeve is provided with a sliding groove, the length direction of which is consistent with the length direction of the main shaft. The limiting pin extends into the sliding groove and abuts against the sleeve.
[0008] Furthermore, the sleeve is provided with a plurality of mounting rings spaced apart along the axial direction of the sleeve, and each mounting ring is provided with a plurality of arch-breaking blades spaced apart along the circumferential direction of the sleeve.
[0009] Furthermore, the housing is provided with a through hole for the main shaft to pass through, and the first mounting base and the second mounting base are respectively located at both ends of the through hole, and the first mounting base and the second mounting base are respectively provided with mounting holes that cooperate with the main shaft.
[0010] Furthermore, the chamber body is provided with a plurality of first threaded holes spaced circumferentially along the through hole, and the first mounting base is provided with first through holes aligned one by one with the first threaded holes.
[0011] Furthermore, the chamber body is provided with a plurality of second threaded holes spaced circumferentially along the through hole, and the second mounting base is provided with second through holes aligned one by one with the second threaded holes.
[0012] Furthermore, the sleeve has a limiting part at one end near the second mounting base, and the limiting part is in contact with the inner wall of the through hole, and the spring abuts against the limiting part.
[0013] Furthermore, the first mounting base is provided with a plurality of spherical heads at equal intervals along the circumference of the sleeve, and the sleeve is provided with a plurality of grooves at equal intervals along the circumference of the sleeve, and the number of grooves is the same as the number of spherical heads.
[0014] Furthermore, the first mounting base is provided with a third threaded hole, and the spherical head is provided with a threaded rod that mates with the third threaded hole.
[0015] Compared with the prior art, this utility model has the following beneficial effects: By using a drive motor to drive the main shaft to rotate, the sleeve and the arch-breaking blades set on the sleeve will rotate. When the arch-breaking blades rotate, they will break up the material accumulated in the hopper, preventing the material from accumulating and arching, causing blockage. As the sleeve rotates, the spherical head set on the first mounting seat will enter or exit the groove on the sleeve. When the spherical head enters the groove, the sleeve will move towards the first mounting seat under the push of the elastic force provided by the spring. At this time, the collision between the sleeve and the first mounting seat will cause the arch-breaking blades to vibrate, so that the material adhering to the arch-breaking blades will fall off. When the spherical head exits the groove, the protruding spherical head will push the sleeve away from the first mounting seat and further compress the spring, so that the sleeve moves back and forth along the axial direction of the main shaft while rotating with the main shaft and collides with the first mounting seat, preventing the material from adhering to the arch-breaking blades and ensuring that the material is continuously and stably discharged from the hopper. It solves the technical problem that the accumulation of material inside the cold material hopper affects the normal feeding of the mixing equipment, and produces the technical effect of preventing the blockage of the cold material hopper caused by the accumulation of material and ensuring that the material in the cold material hopper is smoothly fed into the mixing equipment.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0023] like Figures 1 to 5 As shown in the figure, this utility model embodiment proposes a cold material silo for asphalt production, which is used to store materials during the asphalt production process and to transport materials to the mixing equipment.
[0024] Please refer to Figure 1 , Figure 2 and Figure 3The asphalt production cold silo includes a frame 1 and a silo body 2 mounted on the frame 1. The silo body 2 is used to store materials. A rotatable main shaft 3 and a drive motor 4 connected to the main shaft 3 are mounted on the silo body 2. A sleeve 5 is fitted onto the main shaft 3, and anti-bridging blades 51 are mounted on the sleeve 5. When the drive motor 4 drives the main shaft 3 to rotate, the sleeve 5 rotates synchronously and can slide along the axial direction of the main shaft 3. The sleeve 5 also drives the anti-bridging blades 51 to rotate, thus breaking up the materials inside the silo body 2. The silo body 2 is also equipped with a first mounting base 6 and a second mounting base 7. Located at opposite ends of the main shaft 3, the first mounting base 6 has a spherical head 61 on the side near the sleeve 5. The sleeve 5 has a groove 52 for accommodating the spherical head 61. The main shaft 3 is also fitted with a spring 8, and the opposite ends of the spring 8 in the extension and retraction direction respectively abut against the sleeve 5 and the second mounting base 7. During the rotation of the sleeve 5, the spherical head 61 repeatedly enters and exits the groove 52 and acts synchronously with the spring 8 to push the sleeve 5 to reciprocate along the axial direction of the main shaft 3. When the sleeve 5 collides with the first mounting base 6, the arch-breaking blade 51 vibrates, thereby preventing material from adhering to the arch-breaking blade 51.
[0025] Specifically, during the process of feeding the asphalt production cold aggregate bin to the mixing equipment using the method described in this embodiment, the drive motor 4 is started to drive the main shaft 3 to rotate, which in turn drives the sleeve 5 and the anti-bridging blades 51 mounted on the sleeve 5 to rotate. When the anti-bridging blades 51 rotate, they disperse the material accumulated in the bin 2, preventing the material from accumulating and arching, thus preventing blockage. As the sleeve 5 rotates, the spherical head 61 mounted on the first mounting base 6 enters or exits the groove 52 on the sleeve 5. When the spherical head 61 enters the groove 52, the sleeve 5 is supported by the spring 8. Under the force of the elasticity, the sleeve 5 moves towards the first mounting seat 6. At this time, the collision between the sleeve 5 and the first mounting seat 6 causes the arch-breaking blade 51 to vibrate, so that the material adhering to the arch-breaking blade 51 falls off. When the spherical head 61 exits the groove 52, the protruding spherical head 61 pushes the sleeve 5 away from the first mounting seat 6 and further compresses the spring 8. During the rotation of the main shaft 3, the sleeve 5 moves back and forth along the axial direction of the main shaft 3 and collides with the first mounting seat 6, preventing the material from adhering to the arch-breaking blade 51. The cold aggregate bin for asphalt production provided in this embodiment ensures that the material can break up the accumulated material, thereby preventing the cold aggregate bin from being blocked due to the accumulation of material, and preventing the material from adhering to the arch-breaking blade 51, so that the material can be continuously and stably discharged from the bin body 2 and fed into the mixing equipment.
[0026] like Figure 1 and Figure 2 As shown, the output end of the drive motor 4 is provided with a drive gear 41, and one end of the main shaft 3 is provided with a driven gear 31, which meshes with the drive gear 41. Through the meshing of the drive gear 41 and the driven gear 31, the power output by the drive motor 4 is transmitted to the main shaft 3, causing the main shaft 3 to rotate continuously under the drive of the drive motor 4. This, in turn, drives the arch-breaking blades 51 to rotate continuously within the hopper 2 and break up the material within the hopper 2.
[0027] Please combine Figure 3 and Figure 4 The main shaft 3 is provided with a limiting pin 32, the axial direction of which is consistent with the radial direction of the main shaft 3. The sleeve 5 is provided with a sliding groove 53, the length direction of which is consistent with the length direction of the main shaft 3. The limiting pin 32 extends into the sliding groove 53 and abuts against the sleeve 5. With the limiting pin 32 inserted into the sliding groove 53 on the sleeve 5, when the main shaft 3 rotates, the limiting pin 32 abuts against the sleeve 5, causing the sleeve 5 to rotate synchronously with the main shaft 3. When the sleeve 5 moves axially and reciprocally under the pressure of the ball head 61 and the spring 8, the limiting pin 32 slides in the sliding groove 53, allowing the sleeve 5 to slide relative to the main shaft 3 while preventing unexpected deflection of the sleeve 5, thus improving the reliability of the cold silo for asphalt production during operation.
[0028] In this embodiment, six mounting rings 54 are spaced apart along the axial direction of the sleeve 5, and three anti-bridging blades 51 are spaced apart along the circumference of the sleeve 5 on each mounting ring 54. The mounting rings 54 on the sleeve 5 are used to connect the anti-bridging blades 51, and the six mounting rings 54 are spaced apart on the sleeve 5, and three anti-bridging blades 51 are equally spaced along the circumference of each sleeve 5, so as to increase the contact area between the anti-bridging blades 51 and the material in the hopper 2, and prevent material accumulation in local areas of the hopper 2.
[0029] like Figure 3 and Figure 4As shown, the silo body 2 has a through hole 21 for the main shaft 3 to pass through. The first mounting base 6 and the second mounting base 7 are respectively located at both ends of the through hole 21, and the first mounting base 6 and the second mounting base 7 are respectively provided with mounting holes 62 that mate with the main shaft 3. When assembling the cold aggregate silo for asphalt production, first insert the main shaft 3 into the through hole 21, then install the first mounting base 6 and the second mounting base 7 to both ends of the through hole 21, and insert both ends of the main shaft 3 into the corresponding mounting holes 62, thereby installing the main shaft 3 onto the silo body 2 and ensuring a reliable fit between the main shaft 3 and the silo body 2.
[0030] Please refer to Figure 3 and Figure 5 The chamber body 2 has six first threaded holes 22 spaced circumferentially along the through hole 21, and the first mounting base 6 has first through holes 63 aligned with each of the first threaded holes 22. After the first mounting base 6 is installed on the chamber body 2, it can be fixed to the chamber body 2 by passing screws through the first through holes 63 and engaging with the first threaded holes 22, thus ensuring a secure fit between the first mounting base 6 and the chamber body 2.
[0031] In detail, the silo body 2 is provided with six second threaded holes spaced circumferentially along the through hole 21, and the second mounting base 7 is provided with second through holes aligned with the second threaded holes. The second mounting base 7 is fixed to the silo body 2 by using screws passing through the second through holes and engaging with the second threaded holes, which facilitates the installation of the second mounting base 7 while ensuring that the position of the second mounting base 7 on the silo body 2 remains stable, thereby improving the overall structural stability of the asphalt production cold aggregate silo.
[0032] like Figure 2 and Figure 4 As shown, the sleeve 5 has a limiting part 55 at one end near the second mounting base 7, and the limiting part 55 fits against the inner wall of the through hole 21. The spring 8 abuts against the limiting part 55. The limiting part 55 at the end of the sleeve 5 is used to separate the through hole 21 from the internal space of the chamber 2, to prevent material from entering the through hole 21 and affecting the operation of the main shaft 3 and the spring 8, and to keep the spring 8 abutting against the sleeve 5 during the extension and retraction process, ensuring the stable cooperation between the sleeve 5 and the spring 8.
[0033] Please combine Figure 3 , Figure 4 and Figure 5The first mounting base 6 has six spherical heads 61 evenly spaced along the circumference of the sleeve 5, and the sleeve 5 has six grooves 52 evenly spaced along the circumference of the sleeve 5. By equally spaced six spherical heads 61 on the first mounting base 6 and six equally spaced grooves 52 on the sleeve 5, the sleeve 5 moves back and forth once every 60° rotation and collides with the first mounting base 6, thereby controlling the vibration frequency of the arch-breaking blade 51 to shake off the material adhering to the arch-breaking blade 51, thus achieving automatic cleaning of the arch-breaking blade 51.
[0034] Specifically, the first mounting base 6 is provided with a third threaded hole, and the spherical head 61 is provided with a threaded rod 64 that mates with the third threaded hole. The spherical head 61 is installed on the first mounting base 6 through the mating of the threaded rod 64 and the third threaded hole, which helps to improve the reliability of the mating between the spherical head 61 and the first mounting base 6 and prevents the spherical head 61 from falling off due to collision between the sleeve 5 and the first mounting base 6.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
