Description

Technical Field

[0001] This invention relates to the field of highway asphalt pavement recycling equipment technology, and in particular to a mobile vibrating screen distribution machine for asphalt pavement. Background Technology

[0002] The field of highway asphalt pavement recycling and maintenance equipment technology mainly focuses on the research and development of engineering equipment for the recycling of waste asphalt pavement materials. Addressing industry pain points such as aging and hardening of old asphalt, waste of milled material, high consumption of traditional maintenance materials, high carbon emissions, and construction pollution, the research revolves around complete sets of processes including plant-mixed hot recycling, in-situ hot recycling, and in-situ cold recycling. It studies core equipment technologies such as waste material crushing and screening, precise heating and temperature control, quantitative blending of recycling agents, integrated mixing and paving, and flue gas dust removal and noise reduction. By optimizing equipment thermal efficiency, high-blending structure of old materials, intelligent batching, and integrated operating mechanisms, the research achieves the restoration of aged asphalt performance, the resource-based recycling of old pavement materials, and the reduction of virgin asphalt aggregate consumption. It balances highway maintenance construction efficiency, pavement service performance, and green, low-carbon environmental protection requirements, serving highway reconstruction and expansion projects as well as routine maintenance projects.

[0003] During asphalt pavement construction, the screening, distribution, and paving uniformity of asphalt mixtures directly affect the pavement construction quality and service life. The differences in material requirements for different ground heights, such as pavement base, surface layer, shoulder, and slope, further increase the requirements for the adaptability of distribution equipment.

A baffle plate slides at the bottom of the discharge box, flexibly adjusting the opening size of the discharge chute to achieve precise control of the feeding speed. When feeding material to higher ground, the opening of the discharge chute is enlarged to accelerate the feeding speed. At the same time, the limiting block of the material limiting device moves away from the traction device as the baffle plate moves, reducing the obstruction of material falling on the traction device and ensuring sufficient material supply to higher ground. When feeding material to lower ground, the opening of the discharge chute is reduced to slow down the feeding speed. The limiting block is moved closer to the traction device to increase the limiting effect on the material, reduce the amount of material paved per unit time, and avoid material accumulation and waste at lower ground. This effectively solves the problem of differentiated material supply at different ground heights, improves paving uniformity, and reduces construction defects caused by material impact.

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] First Embodiment

[0034] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 This is a schematic diagram of the structure of a first embodiment of a mobile vibrating screen distribution machine for asphalt pavement provided by the present invention; Figure 2 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 3 for Figure 1 The diagram shown is a structural schematic of the material limiting device. Figure 4 for Figure 1 The diagram shows the structure of the blocking device. Figure 5 for Figure 1 The diagram shows the structure of the screening device.

[0035] A mobile vibrating screen distribution machine for asphalt pavement includes: a base 1;

[0036] Mounting plate 5, two mounting plates 5 are respectively fixedly installed on the top two sides of the base 1, traction device 6 is provided on both sides of the bottom between the two mounting plates 5, support plate 2 is fixedly installed on both sides of the surface of the mounting plate 5, and a fixed box 3 is fixedly installed on the top of the middle of the four support plates 2, and a screening device 4 is fixedly installed in the middle of the fixed box 3.

[0037] The movable groove 11 is opened on one side of the outer surface of the support plate 2, and a first driving member 13 is fixedly installed on the other side of the outer surface of the support plate 2. A first threaded screw 12 is fixedly connected to the output shaft end of the first driving member 13.

[0038] The blocking device 7 and the two assembly devices 7 are respectively disposed on both sides of the bottom of the screening device 4;

[0039] Material limiting device 8 is fixedly installed on one side of the outer surface of the blocking device 7.

[0040] The screening device 4 includes a feeding box 41, a screening box 42, a feeding trough 43, a sieve plate 44, a discharge box 45, a discharge trough 46, and a vibration motor 47. The feeding box 41 is fixedly installed in the middle of the fixed box 3. The screening box 42 is fixedly installed on the top of the feeding box 41. The feeding trough 43 is opened in the middle of the top of the screening box 42. The sieve plate 44 is disposed inside the feeding trough 43. The discharge box 45 is fixedly installed on the bottom of the feeding box 41. The two discharge troughs 46 are respectively opened in the middle of the bottom of the discharge box 45. The vibration motor 47 is disposed on one side of the surface of the screening box 42.

[0041] The blocking device 7 includes a blocking plate 71, a movable block 72, and a threaded hole 73. The blocking plate 71 is slidably installed on the bottom of the discharge box 45. The two movable blocks 72 are respectively fixedly installed on both sides of the outer surface of the blocking plate 71. The threaded hole 73 is opened in the middle of one side of the outer surface of the movable block 72.

[0042] The material limiting device 8 includes an extension block 81, a fixing block 82, and a limiting block 83. The two extension blocks 81 are respectively fixedly installed on both sides of the surface of the baffle plate 71. The fixing block 82 is fixedly installed on the bottom of one side of the extension block 81. The limiting block 83 is fixedly installed on the bottom of one side of the surface of the two fixing blocks 82.

[0043] A control box 9 is fixedly installed on one side of the outer surface of one of the support plates 2.

[0044] The base 1 is equipped with casters 10 on all four sides of its outer surface.

[0045] The moving block 72 is threadedly engaged with the outer surface of the first threaded screw 12 through the threaded hole 73.

[0046] Vibration motor 47 controls the vibration of screen plate 44 to achieve screening, which is the existing screening technology. Material pumps can be set on both sides of the discharge box 45 to control the connection of discharge trough 46, and the discharge volume on the left and right sides can be independently controlled, which is suitable for various construction scenarios such as equal material distribution and unilateral material replenishment.

[0047] The first drive component 13 adopts a servo motor structure, and its outer surface is covered with a protective shell for protection and waterproofing.

[0048] The working principle of the mobile vibrating screen distribution machine for asphalt pavement provided by this invention is as follows:

[0049] During operation, the screening device 4 first screens the material and drops it onto the top of the traction device 6. The bottom of the screening device 4 is equipped with two discharge troughs 46 on the left and right sides to facilitate material distribution. The material drops onto the surfaces of the two traction devices 6 on the left and right sides of the bottom through the two discharge troughs 46 and is transported to two positions. This allows for independent control of the material output on the left and right sides, and is suitable for various construction scenarios such as equal material distribution and unilateral material replenishment.

[0050] The operator can adjust the discharge speed of the discharge chute 46 according to the paving height and paving speed. When paving on high ground, the impact of falling material is large, which can easily lead to problems such as paving accumulation and discontinuity, resulting in insufficient paving uniformity and insufficient material supply to high ground. At this time, the output shaft of the first drive component 13 rotates, which drives the first threaded screw 12 to rotate. The rotation of the first threaded screw 12 causes the threaded engagement blocking device 7 to slide at the bottom of the discharge box 45, causing the blocking plate 71 to move, thus exposing a larger discharge space in the discharge chute 46, increasing the discharge speed, improving the traction efficiency of the traction device 6, and increasing the thickness of asphalt paving at the same time.

[0051] Furthermore, the movement of the blocking device 7 causes the material limiting device 8 to move, and the limiting block 83 moves away from the traction device 6, causing the asphalt to fall quickly from the surface of the traction device 6.

[0052] When laying asphalt on low ground, the blocking plate 71 can cover the discharge space of the discharge chute 46 to a larger extent. As the blocking plate 71 moves, the distance between the limiting block 83 and the traction device 6 decreases, reducing the efficiency of asphalt laying at the same time and reducing the laying thickness, so as to meet the differentiated material supply needs of ground at different heights.

[0053] Compared with related technologies, the mobile vibrating screen distribution machine for asphalt pavement provided by the present invention has the following advantages:

[0054] This invention provides a mobile vibrating screen distribution machine for asphalt pavement. It achieves efficient screening of asphalt mixtures through a screening device 4. A vibrating motor 47 drives the screen plate 44 within the screening box 42 to vibrate, guiding qualified materials through the feeding chute 43 and feeding box 41 into the discharge box 45. The materials are then distributed via the discharge chute 46 to the traction device 6 below. The design of double discharge chute 46 and double traction device 6 allows for independent control of the discharge volume on both sides, adapting to various construction scenarios such as equal material distribution and unilateral material replenishment. A baffle plate 71 slides at the bottom of the discharge box 45, flexibly adjusting the opening size of the discharge chute 46 to achieve precise control of the discharge speed. The control mechanism controls the material supply. When material needs to be supplied to higher ground, the opening of the discharge chute 46 is increased to accelerate the material feeding speed. At the same time, the limiting block 83 of the limiting device 8 moves away from the traction device 6 as the baffle plate 71 moves, reducing the obstruction of material falling on the traction device 6 and ensuring sufficient material supply to higher ground. When material needs to be supplied to lower ground, the opening of the discharge chute 46 is reduced to slow down the material feeding speed. The limiting block 83 moves closer to the traction device 6 to increase the limiting effect on the material, reduce the amount of material paved per unit time, and avoid material accumulation and waste at lower ground. This effectively solves the problem of differentiated material supply at different ground heights, improves paving uniformity, and reduces construction defects caused by material impact.

[0055] Second Embodiment

[0056] Please refer to the following: Figure 6 , Figure 7 and Figure 8 Based on the first embodiment of this application, a mobile vibrating screen distributor for asphalt pavement is provided. The second embodiment of this application proposes another mobile vibrating screen distributor for asphalt pavement. The second embodiment is merely a preferred embodiment of the first embodiment, and its implementation will not affect the separate implementation of the first embodiment.

[0057] Specifically, the second embodiment of this application provides a mobile vibrating screen distribution machine for asphalt pavement, which differs in that the other two sides of the outer surface of the mounting plate 5 are provided with sliding grooves 15, a second threaded screw 17 is rotatably installed inside the sliding groove 15, a second driving member 16 is provided at one end of the second threaded screw 17, and a cleaning device 14 is slidably installed on one side of the top of the traction device 6.

[0058] The cleaning device 14 includes a scraper 141, a baffle 142, a first connecting block 143, a second connecting block 144, a second threaded block 145, and a second threaded hole 146. The scraper 141 is slidably mounted on one side of the top of the traction device 6. The two baffles 142 are respectively fixedly mounted on both sides of the surface of the scraper 141. The first connecting block 143 is fixedly mounted on one side of the top of the baffle 142. The second connecting block 144 is fixedly mounted on the bottom of one side of the surface of the first connecting block 143. The second threaded block 145 is fixedly mounted on one side of the outer surface of the second connecting block 144. The second threaded hole 146 is opened in the middle of one side of the outer surface of the second threaded block 145.

[0059] The second threaded block 145 is threadedly engaged with the outer surface of the second threaded screw 17 through the second threaded hole 146.

[0060] The second drive unit 16 adopts a servo motor structure, and the outer surface is covered with a protective shell to protect the motor and avoid the impact on the motor during rinsing.

[0061] The working principle of the mobile vibrating screen distribution machine for asphalt pavement provided by this invention is as follows:

[0062] During operation, when rinsing the traction device 6, the output shaft of the second drive component 16 rotates, driving the second threaded screw 17 to rotate. The second threaded screw 17 rotates the second threaded block 145 of the threaded second connecting block 144, causing the scraper 141 to move slowly on the surface of the traction device 6. The scraper 141 scrapes off the asphalt residue on the surface of the traction belt 6.

[0063] After the cleaning is completed, the output shaft of the second drive component 16 rotates in the opposite direction, causing the second threaded screw 17 to rotate in the opposite direction, so that the cleaning device 14 moves back to its original position.

[0064] Compared with related technologies, the mobile vibrating screen distribution machine for asphalt pavement provided by the present invention has the following advantages:

[0065] This invention provides a mobile vibrating screen distribution machine for asphalt pavement. By setting up a linkage structure between the cleaning device 14, the second threaded screw 17, and the second drive component 16, it achieves automated cleaning of residual asphalt on the surface of the traction device 6. The scraper 141 moves across the surface of the traction device 6, effectively scraping away residual asphalt, stones, and other debris adhering to the belt. This avoids the problems of low efficiency, incomplete cleaning, and potential damage to the belt caused by traditional manual cleaning. The baffles 142 on both sides of the scraper 141 prevent the scraped debris from scattering to both sides, ensuring that the cleaned material falls into a designated collection area for subsequent processing. After cleaning, the second drive component 16 reverses its rotation to reset the cleaning device 14, without affecting the normal screening and distribution operations of the equipment. This not only reduces the labor intensity of operators but also maintains the cleanliness of the traction device 6, preventing residual material from hardening and affecting conveying efficiency or causing additional wear to the equipment, thereby extending the service life of the equipment and ensuring the continuity and stability of asphalt paving operations.

[0066] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
