Description

Technical Field

[0001] This utility model relates to the technical field of construction machinery, and more specifically, to an auxiliary device for paving. Background Technology

[0002] When laying asphalt, a paver is used for paving. For areas that cannot be reached by machinery, such as corners, manual paving is required. The asphalt mixture is unloaded to the designated location according to the required quantity and then leveled manually with a rake 2-3 times. During the construction process, the rake should be moistened with an oil-water mixture to prevent the asphalt mixture from sticking to the rake teeth.

[0003] Traditional manual paving rakes lack heating and automatic water spraying devices. Rakes at room temperature tend to accelerate the cooling of asphalt, causing the mixture to segregate or become waste. Oil-water mixtures are also quite cumbersome, requiring the rake to be taken to a specific spraying area for operation, which is time-consuming and labor-intensive. In order to shorten the entire paving and leveling process as much as possible, more manpower must be used, increasing labor costs. Therefore, there is an urgent need to improve the traditional rake. Utility Model Content

[0007] Preferably, the handle includes a grip and a connecting rod. One end of the connecting rod is fixedly connected to the rake head, and the other end is provided with a threaded connection to the grip. The outer diameter of the end is smaller than the outer diameter of the connecting rod, and the length of the end is greater than the depth of the threaded hole on the grip. The plastic bag is fitted onto the end.

[0008] Preferably, the grip, connecting rod, and end are all made of hollow steel pipe.

[0009] Preferably, both the grip and the connecting rod are made of solid wood and have a shaft hole at their center. The end is made of stainless steel and the end of the grip for connecting to the end has a metal connector with an internal thread.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0022] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0023] according to Figure 1-4 As shown, a paving auxiliary device includes a rake body 1, which includes a handle 11 and a serrated rake head 12. The rake head 12 has a heating element inside. The handle 11 has a plastic bladder 2 filled with an oil-water mixture. Several water spray holes are formed on the outer surface of the rake head 12, and the plastic bladder 2 communicates with these holes. The heating element provides heat to the rake head 12, preventing the metal rake head 12 from becoming too cold and accelerating the asphalt's hardening, which would affect the paving effect. The oil-water mixture in the plastic bladder 2 provides continuous or intermittent anti-sticking protection to the rake head 12, making operation convenient and effectively improving work efficiency.

[0024] The heating element in this application is set as an electric heating wire, and the wire connecting the electric heating wire extends from the tail end of the handle 11 to the outside. In addition, it should be noted that the heating of the rake head 12 can also be achieved by using heat transfer media such as hot water or hot oil. When using a liquid heating medium, the rake head 12 is welded into a hollow shape using a metal plate.

[0025] according to Figure 1-2 As shown, the handle 11 includes a grip 111 and a connecting rod 112. One end of the connecting rod 112 is fixedly connected to the rake head 12, and the other end has a threaded end 113 for threaded connection with the grip 111. The outer diameter of the end 113 is smaller than the outer diameter of the connecting rod 112, and the length of the end 113 is greater than the depth of the threaded hole on the grip 111. The plastic capsule 2 is fitted onto the end 113. The grip 111, connecting rod 112, and end 113 are all made of hollow steel tubing. Alternatively, the grip 111 and connecting rod 112 are both made of solid wood, and each has a shaft hole at its center. The end 113 is made of stainless steel. The end of the grip 111 for connection with the end 113 has a metal connector with internal threads. Alternatively, the handle 11 can also be made of plastic.

[0026] according to Figure 1-4 As shown, the outer diameter of the plastic bag 2 is greater than or equal to the outer diameter of the connecting rod 112. The end of the plastic bag 2 near the handle 111 is provided with an air intake hose and an air valve 3 for bending the air intake hose and then fitting it onto the plastic bag. The air valve 3 has a flared insertion hole 31 inside, and a winding rod 32 is provided near the end of the insertion hole 31 with a smaller diameter. The winding rod 32 is located on the axis of the insertion hole 31.

[0027] The oil-water mixture in the plastic bladder 2 can flow onto the rake head 12 by its own weight. Therefore, when the rake body 1 is working, the rake head 12 is lower than the gripping part at the end of the handle 11, and the handle 11 is in an inclined state, allowing the oil-water mixture to flow automatically. At this time, the valve... Figure 3 As shown, the air intake hose vents air into the plastic bladder 2 to maintain the air pressure balance inside and outside the bladder 2. Additionally, squeezing the plastic bladder 2 by hand can accelerate the flow of the oil-water mixture inside the bladder 2. At this time, the air valve 3... Figure 4 As shown, this prevents the oil-water mixture from flowing out of the air intake hose.

[0028] The oil-water mixture is formed by mixing diesel fuel and water in a ratio of 1:9.
