[0024] This utility model embodiment provides a circulating grinding machine based on modified asphalt processing.

[0025] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4A circulating grinding machine based on modified asphalt processing includes a housing 1 and a receiving box 2 connected to the housing 1. A rotating sleeve 5 is rotatably connected to the inner top wall of the housing 1. A rotating rod 4 is rotatably connected inside the rotating sleeve 5. Blades 6 are fixedly connected to the outer surfaces of both the rotating rod 4 and the rotating sleeve 5. The rotating rod 4 and the rotating sleeve 5 rotate in opposite directions. The rotating rod 4 rotates inside the rotating sleeve 5, and both ends of the rotating rod 4 penetrate the rotating sleeve 5. By driving the rotating rod 4 and the rotating sleeve 5 to rotate in opposite directions, the two sets of blades 6 perform preliminary crushing and grinding on the material falling into the housing 1.

[0026] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 A drive motor 13 is fixedly connected to the top of the housing 1. A drive bevel gear is fixedly connected to the output shaft end of the drive motor 13. Connecting bevel gears are fixedly connected to the upper part of the outer surface of the rotating sleeve 5 and the upper part of the outer surface of the rotating rod 4. The drive bevel gear meshes with the two connecting bevel gears respectively. The two connecting bevel gears are symmetrically arranged about the drive bevel gear. By starting the drive motor 13, the bevel gears and connecting bevel gears are driven to drive the rotating rod 4 and the rotating sleeve 5 to rotate together in opposite directions.

[0027] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 A frustum grinding head 41 is fixedly connected to the middle of the outer surface of the rotating rod 4. A grinding seat 3 is fixedly connected inside the housing 1. The frustum grinding head 41 is located inside the grinding seat 3. The longitudinal section of the grinding seat 3 is frustum-shaped. The top of the frustum grinding head 41 is arc-shaped. The material after preliminary grinding falls into the interior of the grinding seat 3 and is subjected to secondary grinding through the frustum grinding head 41 and the inner wall of the grinding seat 3.

[0028] Please refer to it again. Figure 2 , Figure 3 and Figure 4The inside of the box 1 is hinged with a screen 7 via a pin. The box 1 and the receiving box 2 are connected by a connecting channel. One end of the screen 7 extends into the inside of the receiving box 2 through the connecting channel. The screen 7 is used to screen the ground material and screen out the material that does not meet the particle size requirement. The material on the screen 7 eventually slides into the inside of the receiving box 2 for collection. The material collected in the receiving box 2 can be fed back into the inside of the box 1 for cyclic grinding through the feeding equipment. A collection box 11 is inserted into the inner bottom wall of the box 1, and a receiving box 21 is inserted into the inner bottom wall of the receiving box 2. The collection box 11 is used to collect the material screened out by the screen 7, and the receiving box 21 is used to collect the material that slides off the screen 7. The top of the box 1 is fixedly connected to a discharge port 12, which facilitates the feeding of materials into the box 1.

[0029] Please refer to it again. Figure 2 , Figure 3 and Figure 4 The box 1 is equipped with a shaking mechanism that drives the screen 7 to swing up and down. The shaking mechanism includes a fixed frame 8 fixed inside the box 1. A swing rod 81 is rotatably connected inside the fixed frame 8. The swing rod 81 and the screen 7 are connected by a pull rope. By driving the swing rod 81 to swing around the pivot, the screen 7 is pulled up and down around the pivot by the pull rope, which accelerates the screening efficiency of the screen 7. A support frame is fixedly connected inside the box 1. The bottom of the rotating rod 4 is rotatably connected to the support frame. The support frame is used to stabilize the rotating rod 4 inside the box 1. A striker 42 is fixedly connected to the lower part of the outer surface of the rotating rod 4 to impact the swing rod 81. When the rotating rod 4 rotates, the striker 42 impacts the swing rod 81 to make the swing rod 81 rotate. A spring 71 is fixedly connected to the inner bottom wall of the connecting channel. The other end of the spring 71 is fixedly connected to the screen 7. Under the action of the spring 71, one end of the screen 7 quickly returns to its original position when no force is applied.

[0030] Working principle: Install the device in a suitable location and connect it to the municipal power supply and external control equipment. Feed the material to be ground into the housing 1 through the discharge port 12. Start the drive motor 13, which, under the action of the connecting bevel gear and the drive bevel gear, drives the rotating rod 4 and the rotating sleeve 5 to rotate in opposite directions. The material is initially ground by two sets of blades 6, and then further ground by the inner wall of the grinding seat 3 and the rotating frustum grinding head 41. The ground material falls onto the screen 7 for sieving. The screened material falls into the collection box 11 for collection. When the rotating rod 4 rotates, it hits one end of the swing rod 81 through the impact rod 42, causing the swing rod 81 to swing. Under the action of the pull rope, the screen 7 is pulled upward and flipped. Then, the spring 71 rebounds and drives one end of the screen 7 to return downward. Through the reciprocating shaking of the screen 7, the material on the screen 7 quickly slides off the screen 7 and into the collection box 2, finally falling into the collection box 21 for collection. The material collected in the collection box 21 can be put back into the box 1 for recycling and grinding through the feeding equipment.
