DETAILED DESCRIPTION

[0021] The following is combined with Figure 1 - Figure 4 This application is described in further detail.

[0022] The present application discloses a crushing device for asphalt mixture. Figure 1 , Figure 2 As shown, it includes a crushing box 1, a motor 2 is fixedly installed on the outer surface of the crushing box 1, and the inner wall of the crushing box 1 is rotatably connected to two crushing rollers 3. The output end of the motor 2 is fixedly connected to one of the crushing rollers 3, and each crushing roller 3 is fixedly connected to a gear 4 at one end away from the motor 2. The two gears 4 are meshed with each other. When the motor 2 is started, it will drive the crushing roller 3 fixedly connected to it to rotate, and the mutual meshing of the two gears 4 allows the two crushing rollers 3 to rotate at the same time, and the two rotation directions are opposite. Through the mutual cooperation of the two crushing rollers 3, large particles of asphalt mixture can be crushed.

[0023] See also Figure 2 The inner wall of the crushing box 1 is rotatably connected with a connecting rod 7, one of the gears 4 and the connecting rod 7 is fixedly connected with a first transmission wheel 6 on the side away from the crushing roller 3, and a first transmission belt 5 is provided on the outside of the crushing box 1. The first transmission belt 5 is transmission-connected to the outer surfaces of the two first transmission wheels 6, and the two first transmission wheels 6 are connected by the first transmission belt 5. When the gear 4 rotates, the two first transmission wheels 6 are driven to rotate at the same time, thereby driving the connecting rod 7 to rotate.

[0024] See also Figure 3 Two V-shaped limit frames 10 are fixedly connected to the inner wall of the crushing box 1, and two second filter plates 11 are arranged inside the crushing box 1. The outer surface of each second filter plate 11 is slidably connected to the two V-shaped limit frames 10. Each second filter plate 11 is provided with a first slot 17 on both sides close to the inner wall of the crushing box 1, and four second slots 18 are provided on the outer surface of the crushing box 1. The second filter plate 11 can be inserted along the V-shaped limit frame 10 until the two second filter plates 11 are in contact, and at this time, the first slot 17 will be on the same central axis as the corresponding second slot 18.

[0025] See also Figure 4 Both sides of the crushing box 1 are fixedly connected with a placement box 12, and the inner wall of each placement box 12 is rotatably connected with a bidirectional screw 13, one end of which is fixedly connected with a rotating wheel 20. When the rotating wheel 20 is rotated, the rotating wheel 20 will drive the bidirectional screw 13 connected thereto to rotate.

[0026] See also Figure 4 One end of each bidirectional screw 13 away from the rotating wheel 20 is fixedly connected to the second transmission wheel 14, the outer surface of one second transmission wheel 14 is transmission-connected to the second transmission belt 19, the second transmission belt 19 is transmission-connected to the outer surface of another second transmission wheel 14, and the two second transmission wheels 14 are connected by the second transmission belt 19. At this time, the rotation of the bidirectional screw 13 connected to the rotating wheel 20 will cause the other bidirectional screw 13 to rotate simultaneously through the second transmission belt 19.

[0027] See also Figure 3 , Figure 4 The outer surface of each bidirectional screw 13 is threadedly connected to two connecting blocks 15, and the outer surface of each connecting block 15 is fixedly connected to a plug rod 16. The outer surface of each connecting block 15 is slidably connected to the corresponding placement box 12, and the outer surface of each plug rod 16 is plugged into the corresponding first slot 17 and the second slot 18. The rotation of the bidirectional screw 13 will drive the corresponding two connecting blocks 15 to move in opposite or reverse directions along the bidirectional screw 13 at the same time, and thereby drive the corresponding plug rod 16 to move horizontally, and the second filter plate 11 is fixed by the plugging between the plug rod 16 and the corresponding first slot 17 and the second slot 18.

[0028] See also Figure 2 , Figure 3 The inner wall of the crushing box 1 is rotatably connected to the first filter plate 9, the outer surface of the connecting rod 7 is fixedly connected to the eccentric piece 8, the bottom surface of the first filter plate 9 is slidably connected to the eccentric piece 8, and when the connecting rod 7 rotates, the eccentric piece 8 will be driven to rotate. At this time, the first filter plate 9 will be pressed on the eccentric piece 8 under the action of its gravity. The rotation of the connecting rod 7 will cause the first filter plate 9 to start vibrating through the eccentric piece 8 to prevent asphalt particles from clogging the first filter plate 9.

[0029] The implementation principle of the asphalt mixture crushing device of the embodiment of the present application is as follows: first, the two second filter plates 11 are inserted along the V-shaped limit frame 10 until the two second filter plates 11 are fully inserted, at which time the first slot 17 will be on the same central axis as the corresponding second slot 18, and then the rotating wheel 20 is rotated, and the two second transmission wheels 14 are connected through the second transmission belt 19. The rotation of the rotating wheel 20 will drive the two bidirectional screws 13 to rotate at the same time, and the rotation of the bidirectional screw 13 will drive the corresponding two connecting blocks 15 to move in opposite or reverse directions along the bidirectional screw 13 at the same time, and thereby drive the corresponding insertion rod 16 to move horizontally, and the insertion rod 16 and the second transmission belt 19 are connected. The second filter plate 11 is quickly fixed by plugging the corresponding first slot 17 and second slot 18, and then the motor 2 is started. When the motor 2 is started, the two crushing rollers 3 can rotate simultaneously through the mutual engagement of the two gears 4, and the asphalt mixture is poured into the crushing box 1, so that the asphalt mixture can be crushed. The crushed asphalt mixture will pass through the first filter plate 9, and the two first transmission wheels 6 are connected by the first transmission belt 5. When the gear 4 rotates, it will drive the two first transmission wheels 6 to rotate at the same time, and thereby drive the connecting rod 7 to rotate. At this time, the eccentric 8 starts to rotate, and the first filter plate 9 starts to vibrate through the eccentric 8.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
