Description

Technical Field

[0001] The invention relates to the technical field of asphalt paving, and in particular to a drainage type municipal road asphalt paving device and method. Background Art

[0002] Drainage asphalt pavement, also known as permeable asphalt pavement, refers to a new type of asphalt concrete surface layer with a void ratio of about 20% after compaction, which can form drainage channels inside the mixture. Its essence is an open-graded asphalt mixture with a skeleton-void structure formed by single-size crushed stones according to the embedding mechanism. When paving asphalt, it needs to be paved through an asphalt paving device.

[0003] When the existing asphalt paving device is in use, asphalt is loaded into the receiving hopper on the paving device by a discharge truck, and the asphalt flows from the two ends of the receiving hopper to the middle, and is then transported to the spiral feeding blades for spreading through a conveyor belt. However, the asphalt near the two ends of the receiving hopper slides down the slope under the action of its own gravity. When the asphalt on the slope gradually decreases, part of the asphalt adheres to the slope and cannot slide down smoothly. After the asphalt is retained for a period of time, its temperature decreases. The asphalt with reduced temperature cannot be put into use. If it is not cleaned in time, it will cause certain damage to the subsequently laid asphalt pavement, thereby reducing the use value of the paving device. Summary of the invention

However, the asphalt near the two ends of the receiving hopper slides down the slope under the action of its own gravity. When the asphalt on the slope is gradually reduced, part of the asphalt adheres to the slope and cannot slide down smoothly.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] A drainage-type municipal road asphalt paving device disclosed in the present invention is mainly applied to the existing asphalt paving device. When in use, asphalt is loaded into the receiving hopper on the paving device by a discharge truck, and the asphalt flows from the two ends of the receiving hopper to the middle, and is then transported to the spiral feeding blades for spreading through a conveyor belt. However, the asphalt near the two ends of the receiving hopper slides down the slope under the action of its own gravity. When the asphalt on the slope is gradually reduced, part of the asphalt adheres to the slope and cannot slide down smoothly. After the part of the asphalt is retained for a period of time, its temperature decreases. The asphalt with reduced temperature cannot be put into use. If it is not cleaned in time, it will cause certain damage to the subsequently laid asphalt pavement.

[0035] Reference Figure 1-Figure 13A drainage type municipal road asphalt paving device comprises a paving machine body 1 and two grounding frames 4, the two grounding frames 4 are fixedly connected to the bottom of the paving machine body 1, and one of the grounding frames 4 is provided with a mounting groove 13, a driving motor 3 14 is fixedly connected inside the mounting groove 13, an output shaft of the driving motor 3 14 is fixedly connected to a driving roller 16 through a coupling, one end of the driving roller 16 is connected to one side of the other grounding frame 4 through a bearing, the two grounding frames 4 are connected to the same matching roller 17 through a bearing on the opposite side away from the driving roller 16, the outer side walls of the driving roller 16 and the matching roller 17 are sleeved with a conveyor belt 11, and the two grounding frames 4 are provided with a plurality of mounting grooves 13, and a plurality of mounting grooves 13 are provided with a plurality of mounting grooves 14 ... An adjustable unloading mechanism 2 is provided on the top, and the adjustable unloading mechanism 2 includes a material receiving frame 201, the material receiving frame 201 is fixedly connected to the top of the grounding frame 4, the inner wall of the material receiving frame 201 near the bottom is connected with a self-adjusting unloading plate 203 through a hinge, a deflection groove is opened on the top of the self-adjusting unloading plate 203, the inner walls on both sides of the deflection groove are connected with the same deflection shaft 211 through bearings, the outer wall of the deflection shaft 211 is fixedly connected with a fitting scraper 202, and self-adjusting spring rods 210 are fixedly connected at equal distances on the downward inclined surface of the self-adjusting unloading plate 203, and one end of the self-adjusting spring rod 210 is fixedly connected to the inner inclined surface of the material receiving frame 201.

[0036] In a specific application scenario, when the material transport vehicle is loading asphalt onto the receiving frame 201, initially, more asphalt will slide directly along the self-adjusting unloading plate 203 to the conveyor belt 11. As the amount of asphalt decreases, the self-adjusting spring rod 210 in the compressed state gradually expands, causing the self-adjusting unloading plate 203 to gradually deflect upward, thereby accelerating the sliding of the asphalt. At the same time, the drive motor 216 is started to drive each striking ball 217 to impact the self-adjusting unloading plate 203, putting it in an oscillating state, ensuring that all the asphalt on the self-adjusting unloading plate 203 can be introduced onto the conveyor belt 11, avoiding the retention loss of asphalt, and at the same time, avoiding the retained asphalt from polluting the subsequently delivered asphalt after cooling down.

[0037] Specifically, when the asphalt on the self-adjusting unloading plate 203 is gradually accumulated at its lower position, this part of the asphalt still cannot be introduced into the conveyor belt 11 in the oscillating state, the electromagnet 215 is powered off, and the iron block 214 is separated from the electromagnet 215. The bending spring 213 in the compressed state drives the ejection plate 208 to pop out. After the ejection, the ejection plate 208 is in an upward oscillating state, and the asphalt attached to it is poured onto the conveyor belt 11, further improving the completeness of the asphalt unloading.

[0038] It should be noted that when the angle between the self-adjusting feed plate 203 and the bottom of the material receiving frame 201 gradually increases, the limiting slider 206 slides in the limiting slide groove 207, so that the fitting scraper 202 is always in a fitting state with the side of the material receiving frame 201, avoiding the asphalt from being introduced into the gap between the self-adjusting feed plate 203 and the material receiving frame 201. At the same time, the fitting scraper 202 has a material attachment effect.

[0044] Specifically, after the asphalt is paved, during the movement of the paving machine body 1, the long paving plate 701 performs a preliminary flattening operation on the paved asphalt, and then the forward and reverse motor 706 is started to drive the secondary pressure plate 702 to rotate forward and reverse within a certain angle to achieve secondary flattening. During the secondary flattening process, the hydraulic cylinder 1 705 is adjusted to drive the secondary pressure plate 702 to move back and forth, thereby increasing the number of asphalt flattening times and the flattening range, and further improving the asphalt paving effect.

[0045] It should be noted that when the secondary pressing plate 702 is in the process of forward and reverse rotation, the rotating centrifugal force drives the elastic connecting rods 704 to stretch, and the extended pressing plate 703 presents a certain trajectory to perform three flattening operations on the asphalt. During the three flattening operations, the extended pressing plate 703 will adjust its direction and position according to the rotation direction of the secondary pressing plate 702, so that the extended pressing plate 703 can press and push the asphalt at a high frequency, thereby further improving the asphalt finishing and paving effect.

During the secondary flattening process, adjust the hydraulic cylinder 1 705 to drive the secondary pressing plate 702 to move back and forth, thereby increasing the number of asphalt flattening and the flattening range. When the asphalt paving is completed, the operation is ended.
