Description

Technical Field

[0001] This utility model relates to the field of asphalt processing and application technology, and in particular to a swing-type asphalt mixture unloading port anti-accumulation structure. Background Technology

[0002] During the asphalt processing and production process, asphalt mixtures have high viscosity and are easily affected by temperature changes during unloading, which leads to a decrease in their fluidity and makes them prone to accumulation and blockage at the bottom of the unloading hopper and the unloading port.

[0003] Existing asphalt mixture unloading hoppers often lack effective anti-accumulation structures or rely on fixed mixing components for cleaning. This not only makes it difficult to completely remove accumulated material from different areas within the hopper, easily creating cleaning dead zones, but also may cause structural damage due to uneven stress on the mixing components. Some anti-accumulation devices are complex to operate, requiring frequent manual intervention, which seriously affects unloading efficiency, increases production costs, and fails to meet the production needs of continuous asphalt processing. Therefore, this utility model proposes a swing-type anti-accumulation structure for asphalt mixture unloading ports. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a swing-type asphalt mixture discharge port anti-accumulation structure to solve the problems of easy accumulation and blockage, incomplete cleaning and complicated operation of existing asphalt mixture discharge hoppers, and to achieve the purpose of efficiently removing accumulated materials, expanding the cleaning range and improving structural stability.

[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: providing a swing-type asphalt mixture discharge port anti-accumulation structure, including a discharge hopper, wherein a cleaning mechanism is movably connected to the center of the discharge hopper to realize the stirring and cleaning operation of the asphalt mixture blocked at the bottom of the discharge hopper; A swing assembly is detachably connected to one side of the cleaning mechanism to swing and deflect the cleaning mechanism inside the unloading hopper.

[0006] The present invention is further configured such that the top of the unloading hopper is fixedly connected with a bolt mounting edge.

[0007] Through the above technical solution, the bolt mounting edge can be detachably and fixedly connected to the unloading end of the asphalt processing equipment by bolts. On the one hand, this ensures that the unloading hopper remains relatively stable with the main body of the equipment during the unloading process, avoiding displacement or shaking of the unloading hopper due to equipment vibration, which would affect the unloading accuracy and anti-accumulation effect. On the other hand, it facilitates the subsequent disassembly and maintenance of the unloading hopper and its internal components, reducing the difficulty of maintenance.

[0008] The present invention is further configured such that: the cleaning mechanism includes a fixing block, a motor is bolted to the top of the fixing block, a connecting shaft is fixedly connected to the output shaft end face of the motor, and a spiral blade is fixedly connected to the outer wall of the connecting shaft.

[0009] With the above technical solution, the motor, as the power source, can drive the connecting shaft to rotate around its own axis after being powered on, and the spiral blades on the outer wall of the connecting shaft will rotate together. The spiral structure of the spiral blades can generate axial stirring and pushing force on the asphalt mixture accumulated at the bottom of the unloading hopper. This can not only break up the clumps of mixture and destroy the accumulation structure, but also push the broken mixture downwards along the spiral direction to the unloading port, fundamentally solving the problem of material accumulation and blockage at the bottom of the unloading hopper and ensuring smooth unloading.

[0010] The present invention is further configured such that: rotating shafts are symmetrically fixedly connected to both sides of the fixed block; the end faces of the two rotating shafts respectively penetrate the two side walls of the unloading hopper and are slidably connected to the ear brackets symmetrically fixedly connected to the two side walls of the unloading hopper; springs are sleeved on the outer walls of the two rotating shafts near their end faces; limit blocks are fixedly connected to their end faces; and stabilizing components are fixedly connected to the bottom of the two rotating shafts.

[0011] Through the above technical solution, the fixing block slides with the ear frame of the unloading hopper through the rotating shafts on both sides, so that the fixing block can drive the entire cleaning mechanism to rotate around the axis of the rotating shaft within the ear frame, providing a structural basis for the swing adjustment of the cleaning mechanism; the spring on the outer wall of the rotating shaft can generate elastic buffer when the cleaning mechanism swings or vibrates during operation, absorb vibration energy, reduce rigid impact between the rotating shaft and the ear frame, and reduce component wear; the limiting block can limit the axial displacement of the rotating shaft, prevent the rotating shaft from slipping out of the ear frame, and ensure a stable connection between the cleaning mechanism and the unloading hopper; and the stabilizing component at the bottom of the rotating shaft can further improve the structural stability of the cleaning mechanism and prevent it from shifting during agitation or swing.

[0012] The present invention is further configured such that: the stabilizing component includes a support rod fixedly connected to the bottom of two rotating shafts, the bottom of the two support rods is fixedly connected to a stabilizing sleeve, and the outer wall of the connecting shaft is rotatably connected to the inner wall of the stabilizing sleeve.

[0013] Through the above technical solution, the support rod fixes the stabilizing sleeve between the two rotating shafts, forming a radial support structure for the connecting shaft; the inner wall of the stabilizing sleeve rotates with the outer wall of the connecting shaft, which not only does not affect the rotational movement of the connecting shaft, but also restricts the radial runout of the connecting shaft during rotation, avoiding bending deformation caused by excessive length of the connecting shaft and uneven force, ensuring that the spiral blades can always fully contact the material at the bottom of the discharge hopper, and ensuring the stability and reliability of the stirring and cleaning effect.

[0014] The present invention is further configured such that: the swing assembly includes a cylinder rotatably connected to the outer wall of the unloading hopper, the end face of the drive rod of the cylinder is rotatably connected to a connecting frame, and the connecting frame is fixedly connected to a connecting rod, one end of the connecting rod passes through the unloading hopper through a movable groove opened on the outer wall of the unloading hopper, and the other end is threadedly connected to a fixed block.

[0015] Through the above technical solution, the cylinder serves as the oscillating power source, and its drive rod can extend and retract axially. The drive rod drives the connecting rod to move synchronously through the connecting frame. Since the connecting rod passes through the movable slot of the unloading hopper and is threadedly connected to the fixed block of the cleaning mechanism, the sliding of the connecting rod in the movable slot can be converted into a pushing and pulling force on the fixed block, causing the fixed block to swing around the axis within the ear frame, thereby driving the entire cleaning mechanism to swing and shift inside the unloading hopper. By adjusting the extension and retraction of the cylinder drive rod, the swing angle of the cleaning mechanism can be controlled, expanding the agitation coverage of the spiral blades, effectively removing accumulated materials in different areas at the bottom of the unloading hopper, and avoiding cleaning dead zones.

[0016] The present invention is further configured such that the connecting rod makes a smooth contact movement on the inner wall of the movable groove.

[0017] Through the above technical solution, the smooth fit between the connecting rod and the inner wall of the movable groove can minimize the sliding friction resistance between the two, ensuring that the connecting rod can slide smoothly in the movable groove when the cylinder drives the rod to extend or retract, avoiding the unstable swing or failure to reach the position of the cleaning mechanism due to friction jamming; at the same time, the smooth fit movement can reduce the wear of the connecting rod and the inner wall of the movable groove, extend the service life of both, and ensure the long-term stable operation of the swing component.

[0018] The beneficial effects of this utility model are as follows: 1. The present invention proposes a swing-type asphalt mixture discharge port anti-accumulation structure. The motor drives the connecting shaft and the spiral blade of the cleaning mechanism to rotate. By utilizing the stirring and pushing action of the spiral blade, the asphalt mixture accumulated at the bottom of the discharge hopper can be efficiently dispersed, the material accumulation structure is destroyed and pushed to the discharge port, thus solving the blockage problem at its source. At the same time, the stabilizing sleeve of the stabilizing component provides radial support for the connecting shaft, preventing the connecting shaft from bending and deforming, and ensuring a stable and reliable cleaning effect. 2. The swing-type asphalt mixture discharge port anti-accumulation structure proposed in this utility model uses the cylinder-driven connecting rod of the swing component to drive the cleaning mechanism to swing, which can flexibly adjust the position of the cleaning mechanism, expand the stirring range of the spiral blades, and effectively eliminate the cleaning dead corners in the discharge hopper; and the spring on the outer wall of the rotating shaft can buffer the vibration impact, reduce component wear, improve the stability and service life of the overall structure, reduce maintenance costs, and is suitable for continuous asphalt processing production scenarios.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0022] like Figure 1 and Figure 2 As shown, a swing-type asphalt mixture discharge port anti-accumulation structure includes a discharge hopper 1. The top of the discharge hopper 1 is fixedly connected to a bolt mounting edge 11. The bolt mounting edge 11 can be detachably fixed to the discharge end of the asphalt processing equipment through bolts. On the one hand, it ensures that the discharge hopper 1 remains relatively stable with the main body of the equipment during the discharge process, avoiding displacement or shaking of the discharge hopper 1 due to equipment vibration, which would affect the discharge accuracy and anti-accumulation effect. On the other hand, it facilitates subsequent disassembly and maintenance of the discharge hopper 1 and its internal components, reducing the difficulty of maintenance.

[0023] like Figure 3 and Figure 4As shown, a cleaning mechanism 2 is movably connected to the center of the unloading hopper 1 to agitate and remove the asphalt mixture clogging the bottom of the unloading hopper 1. The cleaning mechanism 2 includes a fixed block 21, with a motor 22 bolted to the top of the fixed block 21. A connecting shaft 23 is fixedly connected to the output shaft end face of the motor 22, and a spiral blade 24 is fixedly connected to the outer wall of the connecting shaft 23. The motor 22 serves as a power source, and when energized, its output shaft can drive the connecting shaft 23 to rotate around its own axis. The spiral blade 24 on the outer wall of the connecting shaft 23 rotates along with it. The spiral structure of the spiral blade 24 can generate axial agitation and pushing force on the asphalt mixture accumulated at the bottom of the unloading hopper 1. This can not only break up the clumps of mixture and destroy the accumulation structure, but also push the broken mixture downwards along the spiral direction to the unloading port, fundamentally solving the problem of material accumulation and blockage at the bottom of the unloading hopper and ensuring smooth unloading. The fixed block 21 is symmetrically fixedly connected to two rotating shafts 25 on both sides. The end faces of the two rotating shafts 25 pass through the two side walls of the unloading hopper 1 respectively, and are slidably connected to the ear brackets 12 symmetrically fixedly connected to the two side walls of the unloading hopper 1. Springs 26 are sleeved on the outer walls of the two rotating shafts 25 near their end faces, and limit blocks 27 are fixedly connected to their end faces. The fixed block 21 slides with the ear brackets 12 of the unloading hopper 1 through the rotating shafts 25 on both sides, so that the fixed block 21 can drive the entire cleaning mechanism 2 to rotate around the axis of the rotating shafts 25 within the ear brackets 12, which is the swing of the cleaning mechanism 2. The adjustment provides a structural foundation; the spring 26 on the outer wall of the rotating shaft 25 can generate elastic buffer when the cleaning mechanism 2 swings or vibrates during operation, absorb vibration energy, reduce rigid impact between the rotating shaft 25 and the ear bracket 12, and reduce component wear; the limiting block 27 can limit the axial displacement of the rotating shaft 25, prevent the rotating shaft 25 from slipping out of the ear bracket 12, and ensure a stable connection between the cleaning mechanism 2 and the unloading hopper 1; while the stabilizing component at the bottom of the rotating shaft 25 can further improve the structural stability of the cleaning mechanism 2 and prevent it from shifting during agitation or swinging.

[0024] like Figure 4 As shown, a stabilizing component is fixedly connected to the bottom of the two rotating shafts 25. The stabilizing component includes a support rod 28 fixedly connected to the bottom of the two rotating shafts 25. A stabilizing sleeve 29 is fixedly connected to the bottom of the two support rods 28. The outer wall of the connecting shaft 23 is rotatably connected to the inner wall of the stabilizing sleeve 29. The support rod 28 fixes the stabilizing sleeve 29 between the two rotating shafts 25, forming a radial support structure for the connecting shaft 23. The inner wall of the stabilizing sleeve 29 and the outer wall of the connecting shaft 23 are rotatably engaged, which does not affect the rotational movement of the connecting shaft 23, and can limit the radial runout of the connecting shaft 23 during rotation. This avoids bending deformation caused by the excessive length of the connecting shaft 23 and uneven force, ensuring that the spiral blade 24 can always fully contact the material at the bottom of the discharge hopper 1, and ensuring the stability and reliability of the stirring and cleaning effect.

[0025] like Figure 2 and Figure 4As shown, a swing assembly 3 is detachably connected to one side of the cleaning mechanism 2 to swing and offset the cleaning mechanism 2 inside the unloading hopper 1. The swing assembly 3 includes a cylinder 31 rotatably connected to the outer wall of the unloading hopper 1. A connecting frame 32 is rotatably connected to the end face of the drive rod of the cylinder 31, and a connecting rod 33 is fixedly connected to the connecting frame 32. One end of the connecting rod 33 passes through the unloading hopper 1 through a movable slot 13 opened on the outer wall of the unloading hopper 1, and the other end is threaded to a fixed block 21. The cylinder 31 serves as the swing power source, and its drive rod can extend and retract axially. The drive rod drives the connecting rod through the connecting frame 32. The rod 33 moves synchronously; since the connecting rod 33 passes through the movable groove 13 of the unloading hopper 1 and is threadedly connected to the fixed block 21 of the cleaning mechanism, the sliding of the connecting rod 33 in the movable groove 13 can be converted into a pushing and pulling force on the fixed block 21, causing the fixed block 21 to swing around the rotating shaft 25 in the ear frame 12, thereby driving the entire cleaning mechanism 2 to swing and shift inside the unloading hopper 1; by adjusting the extension and retraction of the cylinder 31 drive rod, the swing angle of the cleaning mechanism 2 can be controlled, expanding the agitation coverage of the spiral blade 24, effectively removing the accumulated material in different areas at the bottom of the unloading hopper 1, and avoiding cleaning dead corners; The connecting rod 33 moves smoothly against the inner wall of the movable groove 13. The smooth fit between the connecting rod 33 and the inner wall of the movable groove 13 can minimize the sliding friction resistance between the two, ensuring that the connecting rod 33 can slide smoothly in the movable groove 13 when the cylinder 31 drives the rod to extend or retract, avoiding the unstable swing or failure to reach the position of the cleaning mechanism 2 due to friction jamming. At the same time, the smooth fit movement can reduce the wear of the connecting rod 33 and the inner wall of the movable groove 13, extend the service life of both, and ensure the long-term stable operation of the swing assembly 3.

[0026] In use, this utility model first fixes the entire structure to the unloading end of the asphalt processing equipment by bolt mounting edge 11 on the top of the unloading hopper 1. When the asphalt mixture enters the unloading hopper 1 and shows a tendency to accumulate, the motor 22 of the cleaning mechanism 2 is started. The motor 22 drives the connecting shaft 23 and the spiral blade 24 to rotate. The spiral blade 24 agitates and disperses the material at the bottom and pushes it to the unloading port. At the same time, the cylinder 31 of the swing component 3 is started. The cylinder 31 drives the rod to extend and retract, causing the connecting rod 33 to slide in the movable groove 13, thereby pulling the fixed block 21 to swing around the rotating shaft 25, so that the entire cleaning mechanism 2 swings in the unloading hopper 1, expanding the agitation range of the spiral blade 24. During this process, the stabilizing sleeve 29 ensures the stable rotation of the connecting shaft 23, the spring 26 buffers the vibration, and the limiting block 27 prevents the rotating shaft 25 from slipping, together achieving a highly efficient anti-accumulation effect.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
