[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-6 One embodiment provided by this utility model:
[0027] A screening machine for high-stability asphalt production and processing includes:
[0028] The machine body includes the vibrating screen 1, which is an existing product and is not considered a technical protection point of this application. Therefore, it will not be described in detail here.
[0029] The feeding mechanism includes a connecting frame 2, which is fixedly connected to the surface of the vibrating screen 1 to fix the feed hopper 21 to the feed end of the vibrating screen 1. The feed hopper 21 is fixedly connected to the end of the connecting frame 2 away from the vibrating screen 1 for convenient feeding. A mounting plate 22 is fixedly connected to the surface of the feed hopper 21 for mounting a servo motor 23. The servo motor 23 is mounted on the surface of the mounting plate 22 to drive the drive gear 24 to rotate. The drive gear 24 is rotatably connected to the surface of the servo motor 23 to connect the first crushing roller 25 and the first synchronous gear 27. The first crushing roller 25 is fixedly connected to the surface of the drive gear 24 to cooperate with the second synchronous gear 29. The asphalt blocks fed into the feed are crushed. A fixed shaft 26 is fixedly connected inside the feed hopper 21 to connect the first crushing roller 25 and the second crushing roller 210. The surface of the drive gear 24 is meshed with the first synchronous gear 27 to connect the drive gear 24 and the synchronous belt 28. The surface of the first synchronous gear 27 is meshed with the synchronous belt 28 to connect the first synchronous gear 27 and the second synchronous gear 29. The surface of the synchronous belt 28 is meshed with the second synchronous gear 29 to connect the second crushing roller 210. The surface of the second synchronous gear 29 is fixedly connected with the second crushing roller 210 to cooperate with the first crushing roller 25 to crush the asphalt blocks fed into the feed.
[0030] Furthermore, the connecting frames 2 are symmetrically distributed in two sets on the surface of the vibrating screen 1. The feed hopper 21 is fixedly connected to the surface of the vibrating screen 1 through the connecting frames 2. The two sets of connecting frames 2 are symmetrically distributed to fix the feed hopper 21 to the feed end of the vibrating screen 1 so that the high-stability asphalt blocks can be poured into the feed hopper 21 for crushing.
[0031] Furthermore, the fixed shafts 26 are symmetrically distributed in two sets inside the feed hopper 21. One set is connected to the first crushing roller 25, and the other set is connected to the second crushing roller 210. The drive gear 24 is rotatably connected to the surface of the feed hopper 21 via the servo motor 23. The first crushing roller 25 is rotatably connected to the surface of the fixed shaft 26 via the drive gear 24. Starting the servo motor 23 can drive the drive gear 24 to rotate, thereby driving the first crushing roller 25 to rotate and crush the high-stability asphalt block.
[0032] Furthermore, the first synchronous gear 27 is rotatably connected to the surface of the feed hopper 21 via the drive gear 24, and the synchronous belt 28 is rotatably connected to the surface of the feed hopper 21 via the first synchronous gear 27. The rotation of the drive gear 24 drives the first synchronous gear 27 to rotate, causing the synchronous belt 28 to rotate, thereby driving the second synchronous gear 29 to rotate synchronously with the drive gear 24.
[0033] Furthermore, the second synchronous gear 29 is rotatably connected to the surface of the feed hopper 21 via the synchronous belt 28, and the second crushing roller 210 is rotatably connected to the surface of the fixed shaft 26 via the second synchronous gear 29. The rotation of the synchronous belt 28 drives the second synchronous gear 29 to rotate, and the rotation of the second synchronous gear 29 drives the second crushing roller 210 to rotate inside the feed hopper 21, so that the first crushing roller 25 and the second crushing roller 210 rotate in opposite directions, thereby crushing the high-stability asphalt block.
[0034] Furthermore, the unblocking mechanism includes a connecting block 3, which is fixedly connected to the surface of the vibrating screen 1 and is used to connect the adjusting knob 31 and the adjusting screw 32. The adjusting knob 31 is rotatably connected to the surface of the connecting block 3 and is used to drive the adjusting screw 32 to rotate. The adjusting screw 32 is fixedly connected to the surface of the adjusting knob 31 and is used to drive the connecting plate 33 to move. The connecting plate 33 is threadedly sleeved on the surface of the adjusting screw 32 and is used to connect the fixing frame 34. The fixing frame 34 is fixedly connected to the end of the connecting plate 33 away from the connecting block 3 and is used to connect the unblocking rod 35. The unblocking rod 35 is fixedly connected to the surface of the fixing frame 34 and is used to unblock the screen plate on the surface of the vibrating screen 1.
[0035] Furthermore, the adjusting screw 32 is internally rotatably connected to the adjusting knob 31 and the connecting block 3. A connecting groove is provided on the surface of the vibrating screen 1. The connecting plate 33 is movably connected to the inside of the vibrating screen 1 through the adjusting screw 32. Rotating the adjusting knob 31 can drive the adjusting screw 32 to rotate, thereby driving the connecting plate 33 to move inside the vibrating screen 1.
[0036] Furthermore, the fixed frame 34 is internally and movably connected to the vibrating screen 1 via the connecting plate 33. The unblocking rods 35 are evenly distributed on the surface of the fixed frame 34. The unblocking rods 35 are internally and movably connected to the vibrating screen 1 via the fixed frame 34. The movement of the connecting plate 33 drives the fixed frame 34 and the unblocking rods 35 to move synchronously, so that the unblocking rods 35 act on the surface of the screen plate of the vibrating screen 1, pushing out the high-stability asphalt blocks stuck in the screen plate holes and preventing blockage.
[0037] Working principle: When using the vibrating screen 1, firstly, high-stability asphalt blocks are poured into the feed hopper 21. Starting the servo motor 23 drives the drive gear 24 to rotate, which in turn drives the first crushing roller 25 to rotate. The rotation of the drive gear 24 drives the first synchronous gear 27 to rotate, which in turn drives the synchronous belt 28 to rotate, thereby driving the second synchronous gear 29 to rotate synchronously with the drive gear 24. The rotation of the second synchronous gear 29 drives the second crushing roller 210 to rotate inside the feed hopper 21, so that the first crushing roller 25 and the second crushing roller 210 rotate in opposite directions, thereby crushing the high-stability asphalt blocks for subsequent screening. After screening, rotating the adjustment knob 31 drives the adjustment screw 32 to rotate, which in turn drives the connecting plate 33 to move inside the vibrating screen 1. The movement of the connecting plate 33 drives the fixed frame 34 and the unblocking rod 35 to move synchronously, so that the unblocking rod 35 acts on the surface of the screen plate of the vibrating screen 1, pushing out the high-stability asphalt blocks stuck in the screen plate holes and preventing blockage.
[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
