Description

Technical Field

[0001] This utility model relates to the field of spray width adjustment technology, and in particular to a spray width adjustment device for an asphalt chip sealer. Background Technology

[0002] Asphalt-mash synchronous seal vehicle is a specialized piece of equipment used in road construction and maintenance projects to achieve simultaneous paving of asphalt and mash. Through an integrated operating system, it simultaneously spreads asphalt binder and mash on the road surface in proportion to form a seal structure with protective and bonding functions. It can effectively improve the impermeability, wear resistance and service life of the road surface, and is widely used in the construction, reconstruction and preventive maintenance of highways at all levels.

[0003] In actual construction, the adjustability of asphalt spraying width is crucial. Due to significant differences in road widths (e.g., rural roads, urban arterial roads, highways), and the frequent encounter with complex road sections such as curves and intersections, a fixed spraying width is difficult to adapt to diverse operational scenarios. If the spraying width is too large, it leads to asphalt waste and contamination of non-construction areas; if the width is too small, multiple repetitions are required, reducing construction efficiency and potentially affecting the seal coat quality due to improper handling of overlaps. Therefore, achieving flexible adjustment of the asphalt spraying width is a key requirement for improving construction adaptability, saving material costs, and ensuring project quality. Utility Model Content

[0004] The main purpose of this invention is to provide a spraying width adjustment device for an asphalt chip sealer, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A spraying width adjustment device for an asphalt chip sealer includes two adjusting hydraulic rods symmetrically fixedly mounted on a fixed asphalt spraying assembly. Four supporting guide rail assemblies are symmetrically fixedly mounted on the fixed asphalt spraying assembly. Each supporting guide rail assembly consists of a support frame and limiting guide wheels. Two limiting guide wheels are symmetrically and rotatably mounted on the support frame. A movable asphalt spraying assembly is fixedly mounted on the piston rods of both adjusting hydraulic rods. The movable asphalt spraying assembly is simultaneously slidably mounted on both supporting guide rail assemblies and also slidably mounted on the fixed asphalt spraying assembly. Each movable asphalt spraying assembly consists of a second square tube, a guide plate, a second connecting frame, a second shield, and a second nozzle. The guide plate is fixedly mounted on the front end of the second square tube. Two second connecting frames are symmetrically fixedly mounted on one end of the second square tube. The second shield is fixedly mounted on the lower ends of the two second connecting frames. Two second nozzles are symmetrically fixedly mounted on the second square tube, and the second nozzles simultaneously pass downwards through the upper inner wall of the second shield.

[0007] Preferably, the fixed asphalt spraying assembly consists of a first shield, a first square tube, a first connecting frame, a mounting frame, and a first nozzle. There are two first connecting frames, which are symmetrically fixedly installed on the upper end of the first shield. The first square tube is fixedly installed on one end of the two first connecting frames. There are several first nozzles, which are evenly fixedly installed on the first square tube. The first nozzles simultaneously pass downward through the upper side wall of the first shield. The mounting frame is fixedly installed on the upper end of the first square tube.

[0008] Preferably, the first square tube is fixedly installed on the vehicle frame by connecting hydraulic rods, and an asphalt tank is fixedly installed on the vehicle frame. The asphalt tank is connected to the first square tube and the second square tube through a pipeline system.

[0009] Preferably, the adjusting hydraulic rod is fixedly connected to the mounting bracket and the second square tube.

[0010] Preferably, the support frame on the support rail assembly is fixedly installed at the rear end of the first square tube.

[0011] Preferably, the guide plate is movably inserted between two limiting guide wheels on the supporting guide rail assembly, and the upper side wall of the second shield is provided with a fitting groove, and the second shield is movably fitted onto the first shield.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By installing an adjusting hydraulic rod on the fixed asphalt spraying assembly, and a movable asphalt spraying assembly consisting of a second square tube, guide plate, second connecting frame, second shield, and second nozzle on both the adjusting hydraulic rod and the fixed asphalt spraying assembly, the movable asphalt spraying assembly can be slid by adjusting the extension and retraction of the adjusting hydraulic rod. This allows for position adjustment relative to the fixed asphalt spraying assembly, thereby changing the overall spraying width to adapt to the construction needs of different road widths and complex road sections. This avoids problems such as material waste, pollution of non-construction areas, or low efficiency of repetitive work caused by a fixed spraying width. By connecting the movable asphalt spraying assembly to the fixed asphalt spraying assembly with a support guide rail assembly consisting of a support frame and limiting guide wheels, a stable guide can be provided for the sliding of the movable asphalt spraying assembly, ensuring the smoothness and accuracy of its movement.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, an asphalt chip seal vehicle spraying width adjustment device includes two adjusting hydraulic rods 1, which are symmetrically fixedly mounted on a fixed asphalt spraying assembly 2. Four supporting guide rail assemblies 3 are symmetrically fixedly mounted on the fixed asphalt spraying assembly 2. Each supporting guide rail assembly 3 consists of a support frame 13 and two limiting guide wheels 14, which are symmetrically rotated on the support frame 13. A movable asphalt spraying assembly 4 is fixedly mounted on the piston rod of each of the two adjusting hydraulic rods 1. The movable asphalt spraying assembly 4 is simultaneously slidably mounted on both supporting guide rail assemblies 3 and also slidably mounted on the fixed asphalt spraying assembly 2. The movable asphalt spraying assembly 4 consists of a second square tube 15, a guide plate 16, a second connecting frame 17, a second shield 18, and a second nozzle 19. The guide plate 16 is fixedly mounted on the front end of the second square tube 15. Two second connecting frames 17 are symmetrically fixedly mounted on one end of the second square tube 15. The second shield 18 is fixedly mounted on the lower end of the two second connecting frames 17. The second nozzle... Two nozzles 19 are symmetrically fixedly installed on the second square tube 15. The second nozzle 19 passes downward through the upper inner wall of the second shield 18. An adjusting hydraulic rod 1 is set on the fixed asphalt spraying assembly 2. A movable asphalt spraying assembly 4, consisting of the second square tube 15, guide plate 16, second connecting frame 17, second shield 18 and second nozzle 19, is set on the adjusting hydraulic rod 1 and the fixed asphalt spraying assembly 2. The movable asphalt spraying assembly 4 can be slid by adjusting the extension and retraction of the hydraulic rod 1, so as to adjust the position of the movable asphalt spraying assembly 4 relative to the fixed asphalt spraying assembly 2, thereby changing the overall spraying width to adapt to the construction needs of different road widths and complex road sections, and avoid problems such as material waste, pollution of non-construction areas or low efficiency of repetitive work caused by fixed spraying width. The movable asphalt spraying assembly 4 is connected to the fixed asphalt spraying assembly 2 by setting a support guide rail assembly 3 consisting of support frame 13 and limit guide wheel 14, which can provide stable guidance for the sliding of the movable asphalt spraying assembly 4 and ensure the smoothness and accuracy of its movement.

[0021] Specifically, the fixed asphalt spraying assembly 2 consists of a first shield 8, a first square tube 9, a first connecting frame 10, a mounting frame 11, and first nozzles 12. Two first connecting frames 10 are symmetrically fixedly installed on the upper end of the first shield 8. The first square tube 9 is fixedly installed on one end of each of the two first connecting frames 10. Several first nozzles 12 are evenly fixedly installed on the first square tube 9, and each nozzle 12 passes downwards through the upper side wall of the first shield 8. The mounting frame 11 is fixedly installed on the upper end of the first square tube 9. The first square tube 9 is fixedly installed on the frame 5 via a connecting hydraulic rod 6. An asphalt tank 7 is fixedly installed on the frame 5, and the asphalt tank 7 is connected via a pipe... The system is connected to the first square tube 9 and the second square tube 15. When in use, the frame 5 needs to be installed on the vehicle body. At the same time, the vehicle body is also equipped with a gravel spreading device. The asphalt in the asphalt tank 7 is transported to the first square tube 9 of the fixed asphalt spraying component 2 and the second square tube 15 of the movable asphalt spraying component 4 through the pipeline system. Several first nozzles 12 on the first square tube 9 spray asphalt evenly, and the second nozzles 19 of the movable asphalt spraying component 4 spray in coordination. At the same time, the gravel spreading device spreads gravel synchronously to achieve synchronous sealing operation of asphalt and gravel. During the operation, the overall height of the fixed asphalt spraying component 2 can be adjusted by connecting the hydraulic rod 6 to adapt to different construction needs.

[0022] Specifically, the adjusting hydraulic rod 1 is fixedly connected to the mounting bracket 11 and the second square tube 15. The support bracket 13 on the support guide rail assembly 3 is fixedly installed at the rear end of the first square tube 9. The guide plate 16 is movably inserted between the two limiting guide wheels 14 on the support guide rail assembly 3. The upper side wall of the second shield 18 is provided with a fitting groove 20. The second shield 18 is movably fitted onto the first shield 8. When adjusting the asphalt spraying width according to road conditions, the adjusting hydraulic rod 1 is first activated. The piston rod of the adjusting hydraulic rod 1 extends and retracts, driving the movable asphalt spraying assembly 4 fixedly connected to it to move. The guide plate 16 of the movable asphalt spraying assembly 4 is located on the support guide rail assembly 3. The two limiting guide wheels 14 slide between each other, while the second shield 18 slides on the first shield 8 of the fixed asphalt spraying assembly 2. When the movable asphalt spraying assembly 4 moves away from the fixed asphalt spraying assembly 2, the distance between the second nozzle 19 and the first nozzle 12 increases, and the overall spraying width increases. When the movable asphalt spraying assembly 4 moves closer to the fixed asphalt spraying assembly 2, the distance between the second nozzle 19 and the first nozzle 12 decreases, and the overall spraying width decreases. After adjusting to suit the current road width or the needs of complex road sections, the hydraulic rod 1 is stopped, and the adjustment of the asphalt spraying width is completed.

[0023] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
