Description

Technical Field

[0001] This utility model relates to the field of road engineering technology, and in particular to an anti-clogging, fast and uniform spreading machine. Background Technology

[0002] An asphalt spreader is a mechanical device specifically designed for the precise and uniform distribution of liquid asphalt during road construction. It plays a crucial role in road construction and maintenance, primarily used for subgrade preparation, tack coat application, and crack repair during asphalt pavement laying. By using an asphalt spreader, the asphalt material can be ensured to be evenly distributed across the road surface, thereby improving road quality and service life.

[0003] Existing asphalt spreaders have some technical problems in practical use, especially in the case of asphalt clumping and nozzle blockage after long-term storage and spraying operations. Because asphalt itself has a certain viscosity and temperature sensitivity, prolonged storage in tanks or improper temperature control can easily lead to localized cooling, solidification, or even clumping, thus affecting its fluidity. This not only causes problems during asphalt transportation but can also clog pipes or nozzles during spraying, severely impacting construction efficiency and spray uniformity.

[0004] Furthermore, after spraying operations are completed, the nozzles are typically exposed to the air. If they are not cleaned promptly or if effective protective measures are not implemented, the asphalt residue inside the nozzles or at the outlet will rapidly solidify due to the drop in temperature, forming lumps and further increasing the risk of nozzle clogging. This phenomenon not only increases the frequency and difficulty of equipment maintenance but may also lead to problems such as uneven spraying and unstable flow rates, affecting the quality of road construction. Utility Model Content

[0005] The purpose of this invention is to provide an anti-clogging, rapid, and uniform asphalt spreader that avoids problems such as clumping and nozzle blockage caused by the viscosity and temperature sensitivity of asphalt after long-term storage or spraying, which affect the fluidity and spray uniformity of existing asphalt spreaders. After spraying, the nozzles are exposed to air, and the residual asphalt easily cools and solidifies, further increasing the risk of blockage, increasing maintenance difficulty, and affecting construction quality.

[0006] This utility model provides an anti-clogging, rapid, and uniform spreading machine, including a mobile device. An asphalt storage tank is installed on the top of the rear side of the mobile device. A transmission pipe is connected to the rear side of the asphalt storage tank. An electromagnetic valve is installed on the outer surface of the transmission pipe. A fixing plate is fixedly connected to the rear side of the mobile device. A heating assembly is provided on the top of the fixing plate. The heating assembly includes a heating box and a rotating rod. A heating cylinder is fixedly connected to the center of the inner cavity of the heating box. A separation cylinder is provided at the center of the inner cavity of the heating cylinder. The top end of the rotating rod penetrates into the inner cavity of the heating cylinder and is fixedly connected to the bottom end of the separation cylinder. A heating coil is installed on the inner wall of the heating cylinder.

[0007] In one specific implementation, a protective box is fixedly connected to the bottom of the fixed plate, and a first motor is fixedly connected to the inner cavity of the protective box. The output shaft of the first motor is fixedly connected to the side opposite to the rotating rod, and one end of the transmission pipe extends through to the top of the inner cavity of the heating box and is aligned with the top of the separation cylinder.

[0008] In one specific implementation, a mounting box is fixedly connected to the top of the heating box, a second motor is fixedly connected to the inner cavity of the mounting box, a long rod is fixedly connected to the output shaft of the second motor, and the bottom end of the long rod extends through the inner side of the separation cylinder and is fixedly connected to a stirring blade.

[0009] In one specific implementation, a plurality of connecting rods are fixedly connected to the outer surface of the separation cylinder, and a scraper is fixedly connected to the end of the connecting rod away from the separation cylinder. A conveying pipe is connected to the bottom of the inner cavity of the heating cylinder.

[0010] In one specific implementation, a positioning plate is fixedly connected to the bottom of the fixing plate, and an asphalt pump is fixedly connected to the top of the positioning plate. The inlet end of the asphalt pump is connected to the bottom end of the conveying pipeline.

[0011] In one specific implementation, a plurality of welding plates are fixedly connected to the bottom of the positioning plate, and a storage pipe is rotatably connected to the inner side of the welding plate, and the surface of the storage pipe is in communication with the discharge end of the asphalt pump.

[0012] In one specific implementation, the surface of the storage pipe is connected to a plurality of conical nozzles, and a guide plate is fixedly connected to the outer surface of the storage pipe.

[0013] In one specific implementation, a short rod is fixedly connected to the inner side of the guide plate, and a short plate is fixedly connected to the bottom of the fixing plate.

[0014] In one specific implementation, a placement block is rotatably connected to the inner side of the short plate, and an electric telescopic rod is fixedly connected to one side of the placement block.

[0015] In one specific implementation, the output end of the electric telescopic rod is fixedly connected to the surface of the short rod.

[0016] The beneficial effects of this application are as follows: By setting up a heating component, not only is continuous heating of the asphalt achieved, effectively preventing clumping due to temperature drop, but the heating component also uniformly stirs the asphalt, improving its fluidity and spray uniformity. Simultaneously, the separation device, based on heating and stirring, further separates impurities or lumps from the asphalt, ensuring that the asphalt delivered to the nozzle has good fluidity and consistency, thereby significantly reducing the risk of pipe and nozzle blockage.

[0017] In addition, the heating assembly is equipped with a nozzle oscillation function. The heating assembly drives the nozzle to oscillate, preventing asphalt from remaining at the nozzle for extended periods and causing it to cool and solidify, thus further preventing nozzle clogging. This effectively improves the working stability and construction efficiency of the asphalt spreader, extends the equipment's service life, and ensures the quality and continuity of spraying operations.

[0028] To address the issues of clumping and nozzle blockage caused by the viscosity and temperature sensitivity of asphalt in existing asphalt spreaders after prolonged storage or spraying, which affect flowability and spray uniformity, and the problem of residual asphalt cooling and solidifying after spraying, further exacerbating the risk of blockage, increasing maintenance difficulty, and impacting construction quality, the inventors have developed an anti-clogging, rapid, and uniform asphalt spreader. The heating component not only provides continuous heating and uniform mixing of the asphalt, improving its flowability and spray uniformity, but also removes impurities and lumps through a separation device, reducing the risk of pipe and nozzle blockage. Simultaneously, the nozzles can oscillate under the influence of the heating component, preventing asphalt from solidifying and ensuring continuous spraying operations and stable equipment operation, thus resolving the aforementioned shortcomings.

[0029] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

An electromagnetic valve 22, a multi-functional ZDF-F series electromagnetic valve, is mounted on the outer surface of the transmission pipe 21 and is electrically connected to the mobile device 1. A fixing plate 23 is fixedly connected to the rear side of the mobile device 1. A heating assembly 3 is provided on the top of the fixing plate 23. The heating assembly 3 includes a heating box 31 and a rotating rod 35. The bottom of the heating box 31 is fixedly connected to the top of the fixing plate 23. A heating cylinder 32 is fixedly connected to the center of the inner cavity of the heating box 31, and a separation cylinder 36 is provided at the center of the inner cavity of the heating cylinder 32. The top end of the rotating rod 35 penetrates into the inner cavity of the heating cylinder 32 and is fixedly connected to the bottom end of the separating cylinder 36. The area where the rotating rod 35 penetrates into the heating cylinder 32 is sealed. A heating coil 324 is installed on the inner wall of the heating cylinder 32. Heat dissipation holes are provided on both the left and right sides of the heating box 31. A protective box 33 is fixedly connected to the bottom of the fixing plate 23. A first motor 34 is fixedly connected to the inner cavity of the protective box 33. The output shaft of the first motor 34 is fixedly connected to the opposite side of the rotating rod 35. One end of the transmission pipe 21 penetrates into the top of the inner cavity of the heating box 31 and is aligned with the top of the separating cylinder 36 to facilitate the flow of asphalt into the separating cylinder 36. A mounting box 37 is fixedly connected to the top of the heating box 31. A second motor 38 is fixedly connected to the inner cavity of the mounting box 37.

[0031] Please refer to Figures 2 to 8 The output shaft of the second motor 38 is fixedly connected to a long rod 39. The bottom end of the long rod 39 extends through the inner side of the separation cylinder 36 and is fixedly connected to a stirring blade 310. Several connecting rods 311 are fixedly connected to the outer surface of the separation cylinder 36. A scraper 312 is fixedly connected to the end of the connecting rod 311 away from the separation cylinder 36, and the side of the scraper 312 away from the connecting rod 311 contacts the inner wall of the heating cylinder 32. A conveying pipe 313 is connected to the bottom of the inner cavity of the heating cylinder 32. A positioning plate 314 is fixedly connected to the bottom of the fixing plate 23. An asphalt pump 315 is fixedly connected to the top of the positioning plate 314. The feed end of the asphalt pump 315 is connected to the bottom end of the conveying pipe 313. Several welding plates 316 are fixedly connected to the bottom of 314. A storage pipe 317 is rotatably connected to the inner side of the welding plate 316. The surface of the storage pipe 317 is connected to the discharge end of the asphalt pump 315. Several conical nozzles 318 are connected to the surface of the storage pipe 317. A guide plate 319 is fixedly connected to the outer surface of the storage pipe 317. A short rod 320 is fixedly connected to the inner side of the guide plate 319. A short plate 321 is fixedly connected to the bottom of the fixed plate 23. A placement block 322 is rotatably connected to the inner side of the short plate 321. An electric telescopic rod 323 is fixedly connected to one side of the placement block 322. The output end of the electric telescopic rod 323 is fixedly connected to the surface of the short rod 320.

[0032] Specifically, when asphalt is transported to the separation cylinder 36 through the transmission pipe 21, the heating coil 324 is first activated to heat the asphalt, thereby reducing its viscosity and preventing it from caking upon cooling. Subsequently, the second motor 38 is activated, which drives the long rod 39 to rotate. The long rod 39 further drives the stirring blades 310 to fully stir the asphalt, thereby effectively breaking up the caking asphalt caused by storage.

[0033] While stirring, the first motor 34 is started, which drives the rotating rod 35 to rotate. The rotating rod 35 drives the separating cylinder 36 to rotate synchronously. Centrifugal force is used to separate the stirred asphalt from the separating cylinder 36 and transport it to the heating cylinder 32 for further heat preservation. During the transportation process, the separating cylinder 36 drives the scraper 312 to push the asphalt in the heating cylinder 32, so that the asphalt can be transported through the conveying pipe 313, thereby ensuring that the asphalt maintains good fluidity.

[0034] Next, the asphalt pump 315 is started, and the asphalt in the heating cylinder 32 is extracted through the delivery pipe 313 and delivered to the storage pipe 317. Subsequently, the asphalt is delivered through the storage pipe 317 to the cone nozzle 318 for uniform spraying.

[0035] To prevent asphalt from accumulating and cooling at the nozzle during prolonged spraying, causing blockages, the electric telescopic rod 323 can be activated when the conical nozzle 318 has been in use for an extended period. This electric telescopic rod 323 pushes the short rod 320 to move back and forth, which in turn moves the guide plate 319 synchronously. The guide plate 319 then causes the storage pipe 317 and the conical nozzle 318 to swing, achieving an automatic vibration function for the nozzle. This effectively avoids nozzle blockage caused by asphalt clumping or accumulating, improving the stability of the equipment and the spraying effect.

[0036] In summary, the working principle of the anti-clogging rapid uniform spreader of this utility model embodiment is as follows: First, when the user moves the control moving device 1 to the designated location, the asphalt in the asphalt storage tank 2 is transferred to the heating component 3 for heating and separation, thereby avoiding the asphalt from clumping and clogging during the spraying process. Then, the heating component 3 is restarted, and the heating component 3 swings the conical nozzle 318, thereby avoiding the situation where asphalt is retained in the nozzle of the conical nozzle 318, making it easy to use.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
