[0016] The following further elaborates on this application in conjunction with the attached Figures 1 - 3 drawings for a more detailed description.
[0017] It should be noted that the drawings are schematic and not drawn to scale. For the sake of clarity and convenience in the figures, the relative dimensions and proportions of the parts shown in the figures are exaggerated or reduced in size for illustration. Any dimensions are merely exemplary and not limiting. Additionally, the same reference numerals are used for the same structures, elements, or fittings that appear in more than two figures to represent similar features.
[0018] The embodiment of this application discloses an asphalt spraying mechanism for a spreader, which includes a main bracket 1, support arms 2, and a push rod 3. Two support arms 2 are installed at both ends of the top of the main bracket 1 through rotating shafts. One end of the two support arms 2 is installed with two spraying frames 4 through rotating shafts. A one-way hinge 402 is installed between the two spraying frames 4. The top of the main bracket 1 is fixedly installed with a push rod 3, and the output end of the push rod 3 is installed with a movable frame 301. Sliding holes 302 are opened at both ends of the movable frame 301.
[0019] The implementation principle of the embodiment of this application is as follows: The main bracket 1 serves as the support foundation. At both ends of the main bracket 1, two support arms 2 are respectively installed through rotating shafts. The support arms 2 can rotate around the rotating shafts to adjust the angle. The two spraying frames 4 can adjust their positions along with the movement of the support arms 2. Particularly crucial is that the two spraying frames 4 are connected through a one-way hinge 402. This design enables the spraying frames 4 to easily adjust the angle in a specific direction, while remaining relatively stable in the opposite direction, thereby achieving flexible adjustment of the spraying area. By operating the push rod 3, the movable frame 301 can be pushed to move along the direction of the support arm 2, and then, through the lever principle, the angle of the support arm 2 changes. When the push rod 3 pushes the movable frame 301 outwards, the support arm 2 moves inwards to reduce the included angle, driving the spraying frames 4 to be arranged in a V shape. At this time, the spraying area is reduced. When it is necessary to increase the spraying area, the push rod 3 contracts inwards, and the movable frame 301 moves accordingly. Through the lever action of the support arm 2, the spraying frames 4 are arranged in a straight line. At this time, the spraying area reaches the maximum. Through the ingenious cooperation of the push rod 3 and the movable frame 301, rapid and precise adjustment of the angle of the spraying frames 4 is achieved, which can easily adapt to the spraying requirements of roads with different widths and shapes, greatly improving the flexibility of the spraying operation. The operation process of this application is simple and intuitive. Only by controlling the telescopic movement of the push rod 3 can the adjustment of the spraying area be realized. The model of the push rod 3 can be hydraulic or electric, without complex mechanical operations or manual adjustments, significantly improving the work efficiency. Due to the relatively simple structure, the probability of failures is reduced, and the maintenance process is convenient, effectively reducing the equipment maintenance cost.
[0020] Refer to Figure 1 , an installation seat 101 is installed on the back of the main bracket 1. A through hole is provided inside the installation seat 101. Through the combined use of the installation seat 101 and the through hole, the main bracket 1 can be fixed on the spraying machine so that the device can be put into use.
[0021] Refer to Figure 2 , Figure 3 , both ends of the movable frame 301 are movably installed on the support arm 2 through sliding holes 302. Through the combined use of the movable frame 301 and the sliding holes 302, the two support arms 2 can be limited, and when the movable frame 301 moves, the included angle of the two support arms 2 can be forced to change through the sliding holes 302.
[0022] Refer to Figure 1 , a plurality of nozzles 401 are equidistantly arranged inside the spraying frame 4. A pipeline joint is provided at the top of the nozzle 401. The nozzle 401 can be connected to an external spraying pump (not shown in the figure) through the pipeline joint. Through the nozzle 401, asphalt can be evenly sprayed out to complete the spraying operation.
[0023] All the standard parts used in the present utility model can be purchased from the market. The special-shaped parts can be customized according to the descriptions in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art.
