For those skilled in the art, the specific meanings of the above terms in this utility model can be understood by those skilled in the art in specific circumstances.

[0023] like Figure 1-3As shown, the utility model proposes an asphalt concrete screening device, including a protective shell 4 and a bottom plate 3, the protective shell 4 is arranged on the upper end surface of the bottom plate 3, and also includes a screening plate 2, the right side of the upper end surface of the screening plate 2 is penetrated with a plurality of equidistantly distributed screening holes 18, and a protective outer frame 1 is provided at the edge of the upper end surface of the screening plate 2, so as to prevent the asphalt concrete raw materials from falling through the side of the screening plate 2. The front and rear end surfaces of the screening plate 2 are respectively connected to the front and rear inner walls of the protective shell 4 through sliding components, and the feed hopper 7 is arranged on the right side of the upper end surface of the protective shell 4, and the right end surface of the protective shell 4 is penetrated at intervals. There are multiple first electric push rods 6, and the telescopic shafts of the multiple first electric push rods 6 are connected to the right end face of the screening plate 2. A first inclined plate 15 is provided on the left inner wall of the protective shell 4 and below the screening plate 2. A second inclined plate 17 is provided on the right inner wall of the protective shell 4 and below the screening plate 2. The first inclined plate 15 is inclined and a cleaning mechanism is provided on the upper end face of the bottom plate 3. A collecting assembly is placed below the discharge chute between the first inclined plate 15 and the second inclined plate 17. The first inclined plate 15, the second inclined plate 17 and the screening plate 2 are all inclined and their upper end faces are smooth.

[0024] In the present invention, when asphalt concrete is being processed, the asphalt concrete raw materials need to be screened first before they can be processed into asphalt concrete; and when in use, multiple first electric push rods 6 are started, and through the sliding components on both sides, the sliding components on both sides can drive the screening plate 2 to move repeatedly. When the asphalt concrete raw materials are poured through the feed hopper 7, they will fall on the moving screening plate 2, and the asphalt concrete raw materials will be screened through multiple screening holes 18. The screened asphalt concrete raw materials can fall through the inclined surface of the screening plate 2, and the screened waste will fall on the upper end surface of the first inclined plate 15 or the second inclined plate 17. Since the upper end surfaces of the first inclined plate 15 and the second inclined plate 17 are both smoothly inclined, these wastes can fall into the collection component through the discharge trough, and the waste remaining on the first inclined plate 15 can be cleaned into the collection component by starting the cleaning mechanism.

[0025] In an optional embodiment, the sliding assembly includes a slide rail 19 and a slider 20. The slide rails 19 are symmetrically distributed on the front and rear inner walls of the protective shell 4. The opposite sides of the symmetrically distributed slide rails 19 are respectively connected to the two sides of the outer end surface of the screening plate 2 through the slider 20.

[0026] It should be noted that by starting multiple first electric push rods 6, multiple first electric push rods 6 can drive the protective shell 4 to move, and the sliders 20 on both sides of the outer end surface of the protective shell 4 slide in the slide rails 19 on both sides, thereby ensuring the stability of the screening plate 2 during movement.

[0027] In an optional embodiment, the cleaning mechanism includes a pad 8, a second electric push rod 9, a movable plate 11, a third electric push rod 14 and a cleaning assembly. The upper end surface of the first inclined plate 15 is connected to the second electric push rod 9 through the pad 8. The movable plate 11 is arranged on the telescopic shaft of the second electric push rod 9. The telescopic shafts of multiple third electric push rods 14 pass through the movable plate 11 and are connected to the cleaning assembly.

[0028] It should be noted that when it is necessary to clean the waste on the upper end surface of the first inclined plate 15, first start multiple third electric push rods 14. Multiple third electric push rods 14 can drive the cleaning component to descend, so that the cleaning end of the cleaning component contacts the upper end surface of the first inclined plate 15. Then start the second electric push rod 9. The second electric push rod 9 can drive the movable plate 11 to move. Multiple movable plates 11 can drive the cleaning component to move, thereby cleaning the waste on the first inclined plate 15. The cleaned waste can fall into the collection component through the discharge chute.

[0029] In an optional embodiment, the cleaning assembly includes a cleaning brush plate 10, a lifting plate 12 and a scraper 13. The lifting plate 12 is connected to the telescopic shaft of multiple third electric push rods 14. The cleaning brush plate 10 and the scraper 13 are distributed at intervals on the left and right sides of the bottom of the lifting plate 12; the scraper 13 can clean large pieces of waste, and the cleaning brush plate 10 can clean the waste that falls from the scraper 13.

[0030] It should be noted that the lifting plate 12 can be driven to rise and fall by extending and retracting the multiple third electric push rods 14. When the lifting plate 12 is rising and falling, the cleaning brush plate 10 and the scraper 13 can be driven to rise and fall. When the upper end surface of the first inclined plate 15 contacts the cleaning brush plate 10 and the scraper 13, the second electric push rod 9 can be activated to clean the waste on the upper end surface of the first inclined plate 15.

[0031] In an optional embodiment, the collection assembly includes a collection box 16 and a handle 5. The collection box 16 passes through the right end face of the protective shell 4, and the opening of the collection box 16 is located below the discharge trough between the first inclined plate 15 and the second inclined plate 17. The handle 5 is arranged on the right end face of the collection box 16.

[0032] It should be noted that the collection box 16 can be used to collect waste. When the waste inside the collection box 16 reaches a certain level, the handle 5 allows the staff to pull the collection box 16 out from the inside of the protective shell 4, making it convenient for the staff to clean the waste inside the collection box 16. After cleaning, the collection box 16 can be inserted into the inside of the protective shell 4.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
