Description

Technical Field

[0001] This invention relates to the field of road paving technology, and more specifically to an emulsified asphalt mixture paving equipment. Background Technology

[0002] Emulsified asphalt is a road construction material with good fluidity at room temperature, formed by dispersing asphalt in water containing emulsifiers through mechanical and chemical action. In particular, adding emulsified asphalt to recycled asphalt mixtures can make the old asphalt material and new material more evenly mixed. It is then laid on the subgrade and road surface by paving equipment, and then manually dispersed and smoothed, and finally rolled and leveled. However, because emulsified asphalt has a certain degree of stickiness, the mixture may stick to the bottom of the hopper.

[0003] For example, Chinese utility model publication CN209602923U provides a paving device for emulsified asphalt. The device includes a paving frame and a metering tank on one side of the main body. The metering tank has a discharge port at its bottom and a storage chamber and a metering chamber inside. The metering tank is placed between fixed blocks, and a rotating shaft is inserted at its center. Both ends of the shaft are fixed to the inner wall of the metering tank via bearings. After all the mixture is poured out, the metering tank is rotated again to connect the receiving port with the hopper, allowing for further metering of the mixture. This solves the problem of inconsistent paving quality caused by the inability to meter the emulsified asphalt mixture during its transport from the discharge hopper to the paving frame. The device ensures the rational utilization of the emulsified asphalt mixture, uniform road paving, and guaranteed quality.

[0004] Analysis of existing technologies reveals that traditional asphalt mixture dumping relies on gravity, the mixture stack cannot be automatically spread out, and manual leveling of the asphalt mixture on the road surface is still required. The width of the paving outlet is limited by the width of the inlet, and emulsified asphalt mixture has a certain degree of stickiness, which can cause the mixture to adhere to the bottom of the hopper. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention proposes an emulsified asphalt mixture paving device to solve the technical problems mentioned in the background art, such as the reliance on gravity during the traditional mixture dumping process, the inability of the mixture to spread automatically, the need for manual leveling of the asphalt mixture on the road surface, the limitation of the paving outlet width by the inlet width, and the fact that emulsified asphalt has a certain degree of viscosity, which can lead to the mixture adhering to the bottom of the hopper.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an emulsified asphalt mixture paving device, comprising: The frame is located on one side of the vehicle body; A feeding assembly is mounted on the frame, and one side of it can extend into the truck bed of the vehicle body; The material spreading mechanism is rotatably disposed within the frame. The material spreading mechanism includes multiple sets of circumferentially multi-layered spreading sliders that are slidably disposed within the material spreading mechanism. The emulsified asphalt mixture discharged from the material feeding component can enter from above the material spreading mechanism, be spread by the spreading sliders, and be discharged from the bottom of the material spreading mechanism. A paving assembly, disposed at the bottom of the frame and connected to the paving mechanism, includes a scraper, which converts the rotational motion of the paving mechanism into the reciprocating motion of the scraper to pave the discharged emulsified asphalt mixture; and A drive component is disposed within the material spreading mechanism to convert the rotation of the material spreading mechanism into driving the material spreading slider to reciprocate within the material spreading mechanism.

[0007] Furthermore, the feeding assembly includes: A housing, disposed on the frame, has a feed trough connected to one end; and Multiple sets of screws are provided, all of which are rotatably arranged inside the housing, and one end of each screw is connected to a first motor.

[0008] Furthermore, the material spreading mechanism includes: A rolling frame is rotatably mounted on the frame, and one end of the rolling frame is connected to a second motor; The partition is provided in multiple sets and is uniformly fixedly connected to the rolling frame shaft in a circumferential direction. It can be combined with the rolling frame to form multiple material receiving spaces for accommodating the emulsified asphalt mixture. Multiple sets of inner sliders are provided, slidably disposed within the rolling frame shaft and magnetically coupled to the spreading slider; and An inner groove is formed inside the rolling frame shaft, and the inner slider can slide within the inner groove.

[0009] Furthermore, each side of the inner groove is parallel to the bottom surface of the material-bearing space.

[0010] Furthermore, the leveling component includes: The first groove is formed at the bottom of the frame, and the scraper can be slidably engaged in the first groove; A push plate is fixedly mounted on the scraper. A swing fork, rotatably mounted on the frame, has a second sliding groove at one end, and the second sliding groove is slidably connected to one end of the scraper; and Multiple sets of drive rods are fixedly connected to one side of the rolling frame. When the drive rods rotate, they can first drive the swing fork to rotate and pull back the scraper, and then drive the push plate forward to push the scraper out. Furthermore, the rolling frame and the partition are made of non-magnetic metal materials.

[0011] Furthermore, the driving component includes: A fixed shaft is fixedly installed on one side of the frame and can coaxially pass into the inner sliding groove. Multiple sets of reciprocating grooves are also spaced apart on the fixed shaft. Multiple sets of crescent-shaped guide blocks are provided, each rotatably disposed inside the inner slider, and the crescent-shaped guide blocks can slide back and forth within the reciprocating groove group.

[0012] Furthermore, the reciprocating groove assembly includes: A first spiral groove is formed on the fixed shaft; and A second spiral groove is formed on the fixed shaft. One end of the second spiral groove is connected to one end of the first spiral groove, and the other end of the second spiral groove is connected to the other end of the first spiral groove. Furthermore, inclined pressure plates are fixedly connected to both sides of the scraper.

[0013] Furthermore, the spreading slider and the inner slider are made of magnetic material.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The feeding component of this equipment can uniformly convey emulsified asphalt mixture to the paving mechanism. Under the action of the driving component, the spreading slider in the paving mechanism can spread the mixture to both sides to increase the paving width. After the paving mechanism pours the mixture onto the road surface, the scraper in the paving component can immediately level the mixture to prevent the difficulty of leveling the mixture from increasing after the temperature drops. Moreover, the scraper is installed on the frame parallel to the bottom surface to ensure that the leveled mixture can achieve a high degree of flatness, saving the subsequent manual leveling process and reducing the health impact of asphalt mixture on construction workers.

[0015] 2. The spreading slider of this equipment can reciprocate within the spreading mechanism. When the spreading mechanism starts to pour the mixture, the mixture remaining in the spreading mechanism will also be scraped off by the spreading slider. The power source for both the spreading slider and the scraper is provided by the rotation of the spreading mechanism, eliminating the need for an additional power source, thus reducing equipment costs. The equipment has a compact and ingenious structure, is easy to operate, and also improves the efficiency of road paving work. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0020] Example: like Figure 1 , 2As shown, this invention provides an emulsified asphalt mixture paving device, including a frame 101, one end of which is connected to a vehicle body 102. A feeding assembly is installed on the frame 101, one end of which can extend into the truck bed of the vehicle body 102. A rotatable paving mechanism is rotatably arranged inside the frame 101. The emulsified asphalt mixture discharged from the feeding assembly can enter from above the paving mechanism, be spread out by rotation, and then be discharged from the bottom of the paving mechanism. Multiple sets of paving sliders 310 are arranged inside the paving mechanism and perform reciprocating linear motion within the paving mechanism. A scraper 401 in the paving assembly can flatten the discharged emulsified asphalt mixture. The feeding assembly includes a housing 201, a feed trough 202, and a screw 203. The frame 101 is fixedly connected to... The system is equipped with a housing 201, one end of which is a discharge port and the other end is connected to a feed trough 202. Multiple sets of screws 203 are rotatably installed inside the housing 201. One end of each screw 203 is fixedly connected to the output shaft of a first motor 204. When the first motor 204 is started, it drives the screws 203 to rotate. The mixture entering from the feed trough 202 is pushed by the screws 203 and discharged from the discharge port of the housing 201 at a uniform speed. The feeding component can reduce the workload of construction personnel, and the discharge frequency and quantity can be kept relatively stable, which helps to improve construction quality and control the quantity of material laid. Multiple sets of pulleys 103 are provided at the bottom of the frame 101, which can distribute the weight of the equipment to the ground and move with construction vehicles.

[0021] like Figures 1 to 6 As shown, the paving mechanism includes a rolling frame 301, a second motor 302, partitions 303, and an inner groove 304. The drive assembly includes a fixed shaft 305, an inner slider 307, and a crescent guide block 308. The reciprocating groove assembly includes a first spiral groove 306 and a second spiral groove 309. The rolling frame 301 is rotatably mounted inside the frame 101. One end of the rolling frame 301 is fixedly connected to the output shaft of the second motor 302. Multiple sets of partitions 303 are fixedly installed inside the rolling frame 301. The partitions 303 can be combined with the rolling frame 301 to form multiple material-bearing spaces for accommodating emulsified asphalt mixture. An inner groove 304 is provided inside the shaft of the rolling frame 301. 04. It should be noted here that the inner slide 304 is polygonal in shape, and the number of corresponding partitions 303 is equal to the number of its sides. The sides of the polygon of the inner slide 304 should be parallel to the bottom surface of the material receiving space. This ensures uniform magnetic force and maximum transmission effect. A fixed shaft 305 is fixedly connected to one side of the frame 101 and coaxially inserted into the inner slide 304. Multiple sets of reciprocating grooves are spaced apart on the surface of the fixed shaft 305. Multiple sets of inner sliders 307 can be slidably installed in the inner slide 304. The shape of the inner slider 307 fits the inner slide 304. The inner slider 307 and the reciprocating groove are slidably connected by crescent guide blocks 308.

[0022] When the second motor 302 starts, it drives the rolling frame 301 to rotate. The inner sliding groove 304 in the rolling frame 301 drives the inner slider 307, which is matched with it, to rotate. Since the crescent guide block 308 installed on the inner slider 307 is engaged in the reciprocating groove assembly, but the fixed shaft 305 is fixed on the frame 101 and does not rotate, the inner slider 307 can only rotate while moving axially under the compression of the reciprocating groove assembly. Since the reciprocating groove assembly is composed of the first spiral groove 306 and the second spiral groove 309 connected end to end, the inner slider 307 will turn back at the connection point of the first spiral groove 306 and the second spiral groove 309, achieving the effect of reciprocating linear motion. Both block 307 and spreading slider 310 are made of magnetic material. Therefore, spreading slider 310 will reciprocate linearly along with inner slider 307. When the emulsified asphalt mixture enters the receiving space, it will pile up together. Multiple sets of reciprocating spreading sliders 310 will take turns spreading the mixture to both sides. When the paving mechanism starts to pour the mixture, the mixture remaining in the paving mechanism will also be scraped off by the spreading slider 310. The power source of spreading slider 310 is provided by the rotation of the paving mechanism, without the need for an additional power source. This equipment has a compact and ingenious structure, is easy to operate, and can increase the paving width without changing the feeding width, thereby improving the efficiency of road paving work.

[0023] like Figure 3As shown, the paving assembly includes a pusher plate 402, a swing fork 403, a second slide groove 404, and a drive rod 405. A first slide groove 104 is provided at the bottom of the frame 101, and a scraper 401 is slidably engaged within the first slide groove 104. A pusher plate 402 and a slanted pressure plate 406 are fixedly connected to the scraper 401. A swing fork 403 is rotatably mounted on the frame 101, and a second slide groove 404 is provided at one end of the swing fork 403. The second slide groove 404 is slidably connected to one end of the scraper 401. Multiple sets of drive rods 405 are fixedly connected to one side of the rolling frame 301. When the rolling frame 301 rotates counterclockwise, the drive rods 405 rotate accordingly. The drive rods 405 contact the swing fork 403 and cause it to rotate clockwise until the swing fork 403 leaves the trajectory of the drive rod 405. The swing fork 403 then causes the scraper 401 to retract, and at this time, the pusher plate 402 advances... The drive rod 405 enters the movement trajectory of the drive rod 405. The drive rod 405 continues to rotate and contacts the push plate 402, pushing it out of the movement trajectory and driving the scraper 401 to extend, thereby realizing the reciprocating motion of the scraper 401. The reciprocating motion of the scraper 401 is used to level the asphalt mixture poured on the bottom surface. After the roller frame 301 of this equipment pours the mixture onto the road surface, the scraper 401, together with the inclined pressure plate 406, can level the mixture immediately, preventing the difficulty of leveling the mixture from increasing after the temperature drops. The roller frame 301 itself rotates to drive the scraper 401 to make reciprocating motion. The scraper 401 is slidably installed on the frame 101 parallel to the bottom surface, ensuring that the leveled mixture can achieve a high degree of flatness, saving the subsequent manual leveling process and reducing the health impact of asphalt mixture on construction workers.

[0024] Specific usage and beneficial effects of the present invention: Construction workers shovel the mixture from the truck bed into the feed trough 202. The screw 203 rotates and conveys the mixture to the material receiving space of the spreading mechanism. The rotating frame 301 drives the inner slider 307 to rotate. Since the crescent-shaped guide block 308 installed on the inner slider 307 is engaged in the reciprocating groove assembly, but the fixed shaft 305 is fixed on the frame 101 and does not rotate, the inner slider 307 can only rotate while moving axially under the compression of the reciprocating groove assembly. Since the reciprocating groove assembly is composed of the first spiral groove 306 and the second spiral groove 309 connected end to end, the inner slider 307 will fold back at the connection point of the first spiral groove 306 and the second spiral groove 309, achieving the effect of reciprocating linear motion. Since both the inner slider 307 and the spreading slider 310 are made of magnetic materials, The spreading slider 310 moves in a reciprocating linear motion along with the inner slider 307, achieving the effect of spreading the mixture to both sides. After the rolling frame 301 pours the mixture onto the road surface, the scraper 401 can immediately level the mixture, preventing the difficulty of leveling the mixture from increasing after the temperature drops. The rolling frame 301 itself rotates to drive the scraper 401 to reciprocate, and the scraper 401 is slidably installed on the frame 101 parallel to the bottom surface, ensuring that the leveled mixture can achieve a high degree of flatness, saving the subsequent manual leveling process, reducing the health impact of asphalt mixture on construction workers. This equipment has a compact and ingenious structure, is easy to operate, and can increase the paving width without changing the feed width, thus improving the efficiency of road paving work.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to the present invention, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
