Problems solved by technology
[0004] The above-mentioned document A) can make up for the shortcomings of the original operation method, and has the technical effect described in the 5-8 line on page 2 of the manual, but there are the following Deficiencies: First, because it heats the asphalt in the asphalt tank by the high-temperature hot air discharged from the exhaust pipe of the gasoline engine when the gasoline engine is working, so the energy consumption is large and energy saving is lost; second, because of the single function, it is difficult to adapt to different In the case of joint filling on the pavement, for example, the structure shown in this patent scheme moves backwards when filling the joints, that is, the traveling wheels move in a backward manner, which is suitable for the slow walking required for the joint filling of asphalt pavement cracks, but for The expansion joints reserved on the cement pavement usually require the traveling wheels to travel forward to meet the speed requirement, otherwise the asphalt will spread to the surfaces on both sides of the expansion joint, causing waste and affecting the view of the cement pavement
In addition, according to common knowledge, since the expansion joints on the cement pavement are relatively narrow, if the road wheels travel in reverse, it is often difficult to make the asphalt outlet end of the asphalt conduit correspond to the expansion joints, because the road wheels travel backwards, and the operator must Backwards, and only when the operator walks forward can the corresponding effect between the asphalt outlet end of the asphalt conduit and the expansion joint be effectively guaranteed; thirdly, because asphalt usually needs to show good flow at a temperature of about 160°C However, it can be seen from the patent scheme that asphalt needs to meet this condition, which requires a lengthy process, thus prolonging the sta
