Description

Technical Field

[0001] This utility model relates to the field of asphalt pavement maintenance technology, specifically to an asphalt pavement maintenance atomizing device. Background Technology

[0002] Asphalt pavement refers to various types of pavement constructed by incorporating asphalt binder into mineral materials. Asphalt binder enhances the ability of paving aggregates to resist damage from traffic and natural factors, resulting in a smooth, dust-free, impermeable, and durable surface. Therefore, asphalt pavement is one of the most widely used high-grade pavements in road construction. Asphalt pavement requires regular maintenance, primarily by applying a fog seal layer. This strengthens the bond between layers and prevents cracking. The fog seal layer is mainly composed of a curing agent and emulsified asphalt, and is typically applied using a mist spraying method.

[0003] According to the asphalt pavement maintenance atomizing device disclosed in patent publication number CN 219470592 U, the device can automatically atomize the asphalt pavement during the traction and movement process, and the fog seal layer coverage is more efficient and uniform. At the same time, it can stir, grind and heat the material to improve the maintenance effect. However, when the device atomizes and sprays the maintenance material, it cannot filter the maintenance material. The particulate impurities in the maintenance material may damage the atomizing nozzle, thereby affecting the subsequent use of the device.

[0004] To address this issue, we propose an atomizing device for asphalt pavement maintenance. Utility Model Content

[0028] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings. Example 1

[0029] like Figure 1-6As shown, this utility model provides a technical solution: an asphalt pavement maintenance atomizing device, including a movable base 1, a material box 2 fixedly installed on the upper part of the movable base 1, a box cover 4 fixedly installed on the upper part of the material box 2, a material pump 5 fixedly installed on the upper part of the movable base 1, a filter box 6 fixedly installed on the upper part of the movable base 1, and a connecting assembly 3 set on the upper part of the movable base 1. The connecting assembly 3 includes a filter mechanism 31 set on the upper part of the movable base 1. A stirring mechanism 32 is set inside the material box 2. The input end of the material pump 5 is connected to the material box 2 through a feed pipe, and the output end of the material pump 5 is connected to the filter box 6 through a discharge pipe. The filter mechanism 31 includes a support plate 311 fixedly installed on the upper part of the movable base 1. A mounting shaft 312 is rotatably connected inside the support plate 311 through a bearing. A spray pipe 313 is fixedly connected to the inner end of the mounting shaft 312. An atomizing nozzle 314 is connected to the lower part of the spray pipe 313. An adjusting disc 315 is fixedly connected to the outer end of the mounting shaft 312. An adjusting hole 316 is provided on the surface of the adjusting disc 315. A bracket 317 is fixedly connected to the outer side of the support plate 311. An adjusting rod 318 is movably connected inside the bracket 317. A round block is fixedly connected to the outer end of the adjusting rod 318. A first spring 319 is fixedly connected to the outer side of the bracket 317. An installation groove is provided inside the filter box 6. An installation frame 3110 is inserted into the installation groove. A filter plate 3111 is fixedly connected inside the installation frame 3110. A sealing ring is fixedly connected to the inner wall of the filter box 6. The sealing ring is located in the gap between the installation frame 3110 and the installation groove. A sliding groove 3112 is provided on the upper part of the filter box 6. A sliding rod 3113 is fixedly connected to the inner wall of the sliding groove 3112. A slider 3114 is slidably connected to the outer wall of the sliding rod 3113. A second spring 3115 is fixedly connected to the inner wall of the sliding groove 3112. A limit block 3116 is fixedly connected to the upper part of the slider 3114.

[0030] In this embodiment, one end of the second spring 3115 is fixedly connected to the slider 3114, the bottom of the limiting block 3116 is fitted to the upper part of the mounting frame 3110, and the spray pipe 313 is connected to the filter box 6 via a connecting pipe at one end near the filter box 6.

[0031] Furthermore, the adjusting rod 318 is snapped into the adjusting hole 316, and the outer end of the first spring 319 is fixedly connected to the round block. Through the cooperation of the mounting frame 3110, filter plate 3111, slide groove 3112, slide rod 3113, slider 3114, second spring 3115, and limit block 3116, the material entering the spray pipe 313 can be filtered to prevent particulate impurities in the material from clogging the atomizing nozzle 314 and affecting subsequent use.

Then, manually engage the adjusting rod 318 with the corresponding adjusting hole 316, and under the action of the first spring 319, the adjusting rod 318 can be engaged with the adjusting hole 316, thereby standing the spray pipe 313 up for storage. This facilitates subsequent transportation of the device and increases the applicability of the device. Example 2

[0033] Based on Example 1, a preferred embodiment of the asphalt pavement maintenance atomizing device provided by this utility model is as follows: Figures 1 to 6 As shown: The stirring mechanism 32 includes a motor 321 fixedly mounted on the upper part of the box cover 4 via a mounting bracket. A rotating shaft 322 is fixedly connected to the output end of the motor 321. A mounting sleeve 323 is fitted on the outside of the rotating shaft 322. A stirring rod 324 is fixedly connected to the outer wall of the mounting sleeve 323. A pressing rod 325 is fixedly connected to the outer wall of the mounting sleeve 323 via the rotating rod. A sloped pressing ring 326 is fixedly connected to the bottom of the box cover 4. A heating plate 327 is fixedly installed inside the material box 2. A second mounting plate 3211 is fixedly connected to the outer wall of the bottom end of the rotating shaft 322. A first mounting plate 328 is fixedly connected to the outer wall of the bottom end of the mounting sleeve 323. A limit rod 329 is fixedly connected to the bottom of the first mounting plate 328. A connecting block is fixedly connected to the bottom end of the limit rod 329. A third spring 3210 is fixedly connected to the bottom of the second mounting plate 3211. A scraper 3212 is fixedly connected to the bottom end of the rotating shaft 322.

[0034] In this embodiment, the rotating shaft 322 is rotatably connected to the cover 4 via bearings, and the top of the pressure rod 325 is provided with ball bearings. Through the cooperation of the motor 321, rotating shaft 322, mounting sleeve 323, stirring rod 324, pressure rod 325, inclined pressure ring 326, heating plate 327, first mounting plate 328, limiting rod 329, third spring 3210, second mounting plate 3211, and scraper 3212, materials such as curing agents can be stirred and mixed, which facilitates subsequent use and further increases the applicability of the device.

[0035] Furthermore, the limiting rod 329 moves through the second mounting plate 3211, and the bottom end of the third spring 3210 is fixedly connected to the connecting block.

[0036] When it is necessary to mix curing agents and other curing materials, the materials are simply added manually into the material box 2 through the feed port connected to the upper part of the box cover 4. Then, the motor 321 drives the rotating shaft 322 to rotate. Under the limiting action of the first mounting plate 328, the limiting rod 329, and the second mounting plate 3211, the stirring rod 324, which is fixedly connected to the outer wall of the mounting sleeve 323, can rotate synchronously, thereby performing preliminary mixing of the materials. When the mounting sleeve 323 rotates, the pressure rod 325 can rotate synchronously. Then, under the elastic force of the third spring 3210, the pressure rod 325 can drive the ball bearing to slide relative to the inclined pressure ring 326, thereby allowing the stirring rod 324 to move up and down during rotation, which can effectively mix the materials in the material box 2, thus facilitating the subsequent atomization spraying operation.
