After being compacted by the original asphalt pavement, the soil will adhere firmly to the surface of the asphalt, and after being squeezed, it will become lumps and difficult to clean. When dealing with the adhered soil, the soil on the surface of the asphalt must first be peeled off, and then the next step of filtering is performed. The commonly used treatment method is to stir and brush the asphalt, and then repeatedly brush the screened asphalt, but this repetitive process has many steps and is inefficient.

[0027] Example

[0028] Reference Figures 1 to 6 , is an embodiment of the utility model, which provides an asphalt construction filtering device, such as Figure 1 , Figure 4 , Figure 5As shown, it includes a shell 100, on which a transmission component 200 for conveying materials is provided, and the conveying surface of the transmission component 200 is provided with screening elements 300 at equal intervals. When conveying materials, the transmission component 200 moves in the opposite direction to the material, the material turns over and peels off impurities, and the impurities fall into the screening slots 300-1 between adjacent screening elements 300, move to the feeding end of the transmission component 200 and are thrown out, and the materials roll to the discharging end of the transmission component 200 and are discharged;

[0029] Specifically, the transmission component 200 is used to transport asphalt blocks. The transmission component 200 is installed on the shell 100, and the transmission component 200 is set in the middle of the shell 100, supported on both sides of the transmission component 200 to prevent the asphalt material from rolling down from both ends of the transmission component 200, and the shell 100 is supported at the feeding end and the discharging end of the transmission component 200 respectively. The height of the feeding end is higher than the discharging end, so that the asphalt material has the potential energy to roll down and turn over. The shell 100 is provided with a guide hopper 103 at the feeding end for loading a large amount of asphalt material;

[0030] like Figure 4-Figure 5 As shown, specifically, the inclined surface 301 of the screening member 300 forms an acute angle with the transmission direction of the conveying surface, and the concave surface 303 of the screening member 300 forms an obtuse angle with the transmission direction of the conveying surface. The top surface 302 is conical, which can smoothly allow the soil blocks and other impurities that fall when the asphalt material is turned over to fall into the screening slot 300-1, and form a blocking force with the moving direction of the material to prevent the impurities from rolling down to the discharge end of the conveying assembly 200 with the asphalt material, so that the screening slot 300-1 of the adjacent screening member 300 is an inverted concave. When the impurities are removed When it moves to the upper end of the throwing boundary 300a of the feeding end of the transmission component 200, the screening element 300 moves, and the debris is thrown out in a parabolic manner. The large-mass broken asphalt and stone pieces are thrown out farther due to their large mass and high density, while the same soil pieces are thrown out at a shorter distance. By setting a collection box at a corresponding distance below the feeding end of the transmission component 200, the broken asphalt pieces are collected, thereby further selecting the asphalt by brushing. The large asphalt pieces then turn over and roll down, and the soil pieces on them are separated from them, thus completing the screening effect.

[0031] For example, Figure 1-Figure 6 As shown, the transmission assembly 200 includes a transmission belt 201, an output shaft 202, a driving part 203 and a driven shaft 204. The output shaft and the driven shaft 204 are connected through the transmission belt 201. One end of the transmission belt 201 located at the driven shaft 204 is a feeding end, and one end of the transmission belt 201 located at the output shaft 202 is a discharging end. The outer surface of the transmission belt 201 is a conveying surface. One end of the output shaft 202 is connected to the output end of the driving part 203. The driving part 203 is arranged on the housing 100. The housing 100 is provided with a supporting leg 101 at the discharging end and a supporting member 102 at the feeding end.

[0032] Specifically, the output shaft of the driving unit 203 is connected to the output shaft, providing the output shaft to rotate, driving the transmission belt 201 to rotate the driven shaft 204. The driving unit 203 can be in the form of a motor frame planetary gear set or an internal combustion engine. Screening pieces 300 are installed at equal intervals on the outer surface of the transmission belt 201, and screening grooves 300-1 are formed between the screening pieces 300. When screening asphalt, the transmission belt 201 is driven by the driving unit 203 in the opposite direction of the movement direction of the potential energy of the asphalt, that is, the asphalt block rolls on the belt, and the belt moves in the opposite direction, so that the asphalt block quickly flips on the belt, separating the surface soil from it. , and can also extend the time that the asphalt blocks are transmitted on the belt, thereby reducing the length of the belt and miniaturizing the device. Then, the separated soil blocks are left in the screen slot 300-1 through the belt-type equidistantly installed screening member 300. When moving to the end of the driven shaft 204, the soil blocks and the mixed small asphalt blocks are thrown out. Due to the different densities of the soil blocks and the asphalt gravel blocks, the throwing distances of the two are different. Furthermore, after the asphalt blocks are brushed once and continue to move, those smaller particles of dust and asphalt will fall down. Since these asphalt blocks contain a large amount of soil, they are no longer of use value, and the brushing process of the asphalt blocks is completed;

[0033] It is worth mentioning that the housing 100 is provided with a support leg 101 at the discharging end, and a support member 102 is provided at the feeding end. The support member 102 is provided with a chute 102a connected to the extension of the housing 100. A buffer portion 102b is provided in the chute 102a, and the buffer portion 102b is respectively connected to the extension and the support member 102;

[0034] Specifically, Figure 1 , Figure 6 As shown, a support member 102 is installed on the housing 100 at the position of the driven shaft 204. The slide groove 102a provided on the support member 102 and the installed buffer part 102b have a vibration reduction and buffering effect on the transmission component 200 and the housing 100 when screening asphalt blocks, which can extend the service life of the equipment. At the same time, appropriate buffering and vibration reduction can prevent the asphalt blocks from falling due to excessive flipping on the belt, and prevent the debris in the screening slot 300-1 from vibrating and falling into the discharge end of the belt, thereby effectively avoiding the effect of impurities and asphalt being mixed again.
