Technical Field
[0001] This utility model relates to the field of asphalt mixing equipment, and in particular to a multifunctional asphalt mixing equipment. Background Technology
[0002] In the current road construction industry, asphalt mixing equipment is a key production equipment, and its technological development level plays a vital role in project quality, efficiency, and cost control. With the continuous advancement of transportation infrastructure construction, whether it is the renovation and upgrading of urban roads or the continuous construction of large-scale projects such as highways and bridges, the demand for asphalt mixtures has been raised to a higher level in terms of both quantity and quality, which poses many challenges to existing asphalt mixing equipment.
[0003] In the integrated technology of thermal virgin recycling of asphalt mixtures, the workload of projects varies. If the mixing equipment manufacturer chooses large-scale equipment to meet the demand for large production capacity, a "large horse pulling a small cart" phenomenon will occur when encountering small production capacity tasks. The high energy consumption and low output of the equipment will create a stark contrast, resulting in a huge waste of energy and a significant increase in equipment operating costs. Conversely, if small equipment is configured, although the energy consumption is relatively low when producing at a small capacity, the production capacity of the equipment is insufficient when facing large-scale projects. The only way to meet the output requirements is to extend the production time, thereby reducing production efficiency. Therefore, a multi-functional asphalt mixing equipment is proposed to solve the above problems. Utility Model Content

[0030] 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.
[0031] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a multifunctional asphalt mixing device, comprising a machine body 1, a machine body 2, and a support 8. Machine body 1 is the main body of a small-capacity forced mixing cylinder, and machine body 2 is the main body of a large-capacity forced mixing cylinder. Both bodies can powerfully mix materials, resulting in high mixing efficiency and the ability to uniformly mix materials in a short time, thus improving production efficiency. The support 8 supports three hoppers: a first hopper 5, a second hopper 6, and a third hopper 7. Feed hoppers are provided on opposite sides of machine body 1 and machine body 2, allowing the mixed material to be conveyed into the mixing cylinders for mixing. Discharge ports are provided on the outer sides of both machine body 1 and machine body 2. The support frame 8 has three hoppers fixedly installed in the middle: hopper 1 (5), hopper 2 (6), and hopper 3 (7). Hopper 1 (5) corresponds to the upper part of the LB2000 small-scale primary equipment, hopper 2 (6) corresponds to the upper part of the RLB3000 large-scale regeneration equipment, and hopper 3 (7) corresponds to the upper part of the LB4000 large-scale primary equipment. Hoppers 1 (5), hopper 2 (6), and hopper 3 (7) are fixedly installed from left to right. A switching component 3 is provided at the bottom of hopper 1 (5). The switching component 3 includes a feeding funnel 31, which can guide the material into the feeding hopper. The bottom of hoppers 1 (5), hopper 2 (6), and hopper 3 (7) are all fixedly connected to a fixed frame 38 that provides support and mounts a baffle 34.
[0032] Furthermore, a vertical funnel 33 is fixedly connected to the bottom of the fixed frame 38 located at the bottom of the second hopper 6. The vertical funnel 33 can directly drop the material vertically, reducing the adhesion effect of recycled material and solving the problem of recycled material sticking. After metering, traditional recycling equipment sends the material to the mixing tank through a chute or belt, and some adhesion will occur. However, the vertical funnel 33 is placed directly above the feed hopper of the second body 2, and the recycled material falls vertically, so there is no adhesion to the chute or belt. The fixed frame 38 located at the bottom of the third hopper 7 is fixedly connected to a vertically inclined funnel 33. An inclined funnel 32 guides the material into the feed hopper and then into the machine body 2 for stirring. A partition 37 is fixedly connected to the middle of the fixed frame 38 at the bottom of the discharge hopper 5 to separate the inside of the fixed frame 38. The inner walls of the three sets of fixed frames 38 are all slidably connected with baffles 34 to block the material. The baffles 34 can be closed or opened according to the required amount for material discharge. The rear surfaces of the multiple sets of baffles 34 are all fixedly connected with guide plates 35 to drive the movement of the baffles 34. The front surfaces of the multiple sets of guide plates 35 are all fixedly connected with cylinders 36 to push the movement of the guide plates 35.
[0033] Furthermore, multiple sets of cylinders 36 are respectively fixedly installed on the outside of multiple sets of fixed frames 38. The second machine body 2 is located on the right side of the first machine body 1. The bracket 8 is located on the upper part of the feed hopper between the first machine body 1 and the second machine body 2. The front surfaces of multiple sets of baffles 34 are all fixedly connected with positioning plates 39 that limit the movement distance of the baffles 34. The positioning plates 39 can restrict the movement of the baffles 34 and prevent them from moving out of the fixed frames 38. The positioning plates 39 are slidably connected to the inner wall of the fixed frames 38. The bottom opening of the discharge funnel 31 is provided with two sets, which are vertically downward and inclined to the right respectively. The two sets of openings are respectively Align the feed hopper on the right side of machine body 1 and the feed hopper on the left side of machine body 2. This allows for the opening and closing of the baffle 34 to enable various production modes. The bottom openings of the vertical funnel 33 and the inclined funnel 32 are aligned with the feed hopper on the left side of machine body 2. The two sets of baffles 34 are respectively set on the inner wall of the bottom fixed frame 38 of the discharge hopper 1 and distributed on the left and right sides of the partition 37. The two sets of baffles 34 are respectively connected to the two sets of openings inside the discharge funnel 31. The discharge of material through the two sets of openings on the inner wall of the discharge funnel 31 can be controlled by the baffles 34 and the cylinder 36.
[0034] Reference Figure 1 , Figure 2 and Figure 3A rotating assembly 4 is provided on the right side of the third hopper 7. The rotating assembly 4 includes two sets of fixed blocks 42 supporting the rotating rod 43 and the servo motor 41, and the servo motor 41 driving the rotating rod 43 to rotate. The two sets of fixed blocks 42 are respectively fixedly connected to the right side of the third hopper 7 and the left side of the first hopper 5. A rotating rod 43 that drives multiple sets of stirring blades 44 to rotate is rotatably connected between the two sets of fixed blocks 42. The right end of the rotating rod 43 passes through the fixed block 42 on the right side of the third hopper 7 and is fixedly connected to the output shaft of the servo motor 41. The servo motor 41 is fixedly installed on the right side of the third hopper 7. On the right side of the fixed block 42, the rotating rod 43 passes through the lower middle part of the first hopper 5, the second hopper 6, and the third hopper 7 respectively. The outer wall of the rotating rod 43 is fixedly connected to the inner wall of the first hopper 5, the second hopper 6, and the third hopper 7. The rotating rod 43 has stirring blades 44 that can rotate and stir to reduce the chance of blockage inside the first hopper 5, the second hopper 6, and the third hopper 7. Multiple sets of stirring blades 44 are respectively set above multiple sets of fixed frames 38. By rotating the multiple sets of stirring blades 44, the material can be pushed during feeding to prevent it from accumulating and causing blockage, thereby improving the feeding efficiency.
[0035] Working principle: When in use, first connect the external power supply and switch to the electrical equipment in this device, then turn on the power supply and each system of the equipment, preheat the LB2000 small-scale original equipment, the RLB3000 large-scale regeneration equipment, and the LB4000 large-scale original equipment, check the status of each component of the equipment, and at the same time, transport all kinds of materials required for production to the corresponding silos to ensure sufficient materials.
[0036] By setting the vertical funnel 33 vertically downwards, the problem of recycled material sticking can be solved. After the traditional recycling equipment is metered, it is sent to the mixing tank through a chute or belt, and more or less will stick. However, the recycling equipment is placed directly above the feed hopper on the left side of the machine body 2, and the recycled material falls vertically, so there is no sticking to the chute or belt.
[0037] When starting small-scale production of raw materials, the LB2000 small-scale raw material equipment starts working. The material enters the equipment through the feeding hopper 5. At this time, the control cylinder 36 opens the baffle 34 located inside the fixed frame 38 at the bottom of the feeding hopper 5 and on the left side of the partition 37. The vertical downward opening of the feeding funnel 31 opens, and the material enters the feeding hopper on the right side of the machine body 1 through this opening and enters the small-capacity mixing tank for mixing.
[0038] When the production capacity of the primary equipment needs to be produced, the LB4000 large-scale primary equipment is put into operation. The material is conveyed through the feeding hopper 37, and the baffle 34 is opened by the cylinder 36. The material is then guided into the feeding hopper on the left side of the machine body 2 by the inclined funnel 32 for mixing.
[0039] When producing large quantities of native equipment, you can choose to start both native small-capacity production mode and native medium-capacity production mode simultaneously to achieve large-capacity production of native equipment.
[0040] When integrated production of primary and recycled materials is required, three production modes can be selected according to the requirements. One mode is to simultaneously open the vertical opening at the bottom of hopper 1 5, the bottom opening at the bottom of hopper 2 6, and the bottom opening at the bottom of hopper 3 7 to carry out primary and recycled production. Another mode is to open the bottom openings at the bottom of hopper 2 6 and hopper 3 7 to the machine body 2 2 for production. A third mode is to open the right-sloping opening on the right side of hopper 1 5 to the machine body 2 2 and the bottom opening at the bottom of hopper 3 7 to the machine body 2 2 for production.
[0041] When a fully recycled equipment is required, a production method can be selected that allows the bottom cylinder 36 of the discharge hopper 26 to open the baffle 34 and the vertical funnel 33 into the machine body 2.
[0042] The above seven production modes can meet different production requirements, reduce the problem of oversized equipment or energy waste, and achieve multi-functional asphalt production and mixing effects.
[0043] After the material enters the mixing tank, the mixing devices inside the machine body 1 and machine body 2 are activated. The small-capacity mixing tank 1, with its mixing structure, performs fine mixing on small batches of material, while the large-capacity mixing tank 2 uses powerful motors to efficiently mix large quantities of material, ensuring uniform mixing. During material conveying, the rotating component 4 on the right side of the discharge hopper 3 7 plays a role. The servo motor 41 drives the rotating rod 43 to rotate, which in turn drives the mixing blades 44 to rotate. The mixing blades 44 mix and propel the material in the discharge hoppers 1 5, 2 6, and 3 7, preventing material accumulation and blockage, ensuring smooth material discharge, and improving overall production efficiency.
[0044] After mixing, the qualified asphalt mixture is discharged from the discharge port of the mixing tank and can be transported to the storage area or directly to the construction site by conveyor belt or other transportation equipment.
[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
