Abstract
Description
Technical Field
[0001] This utility model relates to the field of crusher technology, and in particular to a crusher for crushing asphalt recycled materials. Background Technology
[0002] In the process of recycling asphalt, it is necessary to crush the asphalt. However, since the sources of waste asphalt vary, it may contain some impurities. If it is not screened, the crusher may be damaged during the crushing process due to its hard texture. Screening requires additional time and manpower. Therefore, a new type of crusher is needed to solve this problem. Utility Model Content
[0003] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.
[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a crusher for crushing asphalt recycled materials.
[0005] To achieve the above objectives, the technical solution of this utility model is: a crusher for crushing asphalt recycled materials, comprising a frame and two crushing rollers, both of which are rotatably connected to the frame, one of which is rotatably connected to the frame via a tilting frame, the tilting frame being rotatably connected to the frame, and an elastic mechanism being provided between the tilting frame and the frame.
[0006] By adopting the above technical solution, the overturning mechanism enables one of the crushing rollers to move. When a harder and larger impurity enters the crusher, the movable crushing roller will be pushed away by the interaction force due to the resistance. This causes the overturning mechanism to rotate in the direction that overcomes the elastic force of the elastic mechanism, thereby increasing the distance between the crushing rollers. At this time, the impurity can pass between the two crushing rollers. In this way, when the crushing roller encounters a harder and larger impurity, it can pass through to prevent the crusher from being damaged, thus protecting the equipment.
[0007] Preferably, the elastic mechanism is provided in two sets, and the two sets of elastic mechanisms are respectively located at both ends of the flipping frame.
[0008] This invention uses two sets of elastic mechanisms to ensure that the forces at both ends of the tilting frame are evenly distributed.
[0009] Preferably, the elastic mechanism includes a spring and a support rod. The spring is sleeved on the support rod, one end of the support rod is rotatably connected to the tilting frame, and the other end of the support rod is rotatably and slidably connected to the frame via a connecting mechanism. The two ends of the spring abut against the support rod and the connecting mechanism, respectively. This invention utilizes the support rod and the connecting mechanism to limit the spring's position, ensuring the spring is fixed between the tilting frame and the frame. When the tilting frame rotates, the support rod simultaneously rotates and slides, causing the spring to deform and generate elastic force, allowing impurities to be reset after passing through the tilting frame.
[0010] Preferably, the connecting mechanism includes a rotating rod and two connecting seats, both of which are connected to the frame. Both ends of the rotating rod are rotatably connected to the two connecting seats respectively. One end of the support rod passes through the rotating rod, and the support rod is slidably connected to the rotating rod. This invention, through the slidable connection between the support rod and the rotating rod, allows the support rod to slide only along its length. Simultaneously, the rotatable connection between the rotating rod and the connecting seats allows the support rod to rotate, achieving the desired effect of the connecting mechanism.
[0011] Preferably, both connecting seats are slidably connected to the frame via a sliding mechanism, and the end of the support rod is threaded with an adjusting nut for adjusting the spring compression. This invention utilizes the adjusting nut to adjust the spring compression, thereby adjusting the resistance required for the crushing roller to rotate. Simultaneously, the range of sliding of the support rod changes during adjustment, altering the distance between the two crushing rollers, thus adjusting the particle size of the crusher output. The connecting seats can change position via the sliding mechanism, further increasing the adjustment range.
[0012] Preferably, the sliding mechanism includes a limiting bolt and a limiting nut. The frame has a slide rail. The limiting bolt passes through the connecting seat and the slide rail. The limiting nut is threadedly connected to the limiting bolt and abuts against the frame. This invention utilizes the mutual engagement of the limiting nut and the limiting bolt to press the connecting seat firmly onto the frame, thereby fixing the position of the connecting seat. After the limiting nut is loosened, the connecting seat can slide along the slide rail under the limitation of the limiting bolt, thus achieving adjustment.
[0013] Preferably, the two crushing rollers are driven by two separate motors, one of which is fixedly connected to the tilting frame, and the other is fixedly connected to the machine frame. This invention ensures sufficient crushing force by simultaneously driving the two crushing rollers individually.
[0014] Preferably, both motors are connected to the crushing roller via a reduction gearbox. This invention utilizes the reduction gearbox to adjust the output torque of the motors, making them suitable for the operation of the crusher.
[0015] Preferably, a hopper is provided at the top of the frame. This invention utilizes the hopper to guide materials between the two crushing rollers.
[0016] In summary, the beneficial effects of this utility model are:
[0017] 1. The tilting mechanism allows one of the crushing rollers to move. When a hard and large impurity enters the crusher, the movable crushing roller will be pushed away by the interaction force due to the resistance. This causes the tilting mechanism to rotate in the direction that overcomes the elastic force of the elastic mechanism, thereby increasing the distance between the crushing rollers. At this time, the impurity can pass between the two crushing rollers. In this way, when the crushing roller encounters a hard and large impurity, it can be passed through to prevent the crusher from being damaged, thus protecting the equipment.
[0018] 2. The compression of the spring can be adjusted by using the adjusting nut, which in turn adjusts the resistance required for the crushing roller to rotate. During the adjustment process, the sliding range of the support rod will also change, thus changing the distance between the two crushing rollers and adjusting the particle size of the crusher output. The connecting seat can change position through the sliding mechanism, thereby further increasing the adjustment range.

[0033] like Figure 1-2 As shown, a crusher for crushing asphalt recycled materials includes a frame 1 and two crushing rollers 2. Both crushing rollers 2 are rotatably connected to the frame 1. One of the crushing rollers 2 is rotatably connected to the frame 1 through a tilting frame 3. The tilting frame 3 is rotatably connected to the frame 1, and an elastic mechanism is provided between the tilting frame 3 and the frame 1.
[0034] By adopting the above technical solution, the overturning mechanism enables one of the crushing rollers 2 to move. When a harder and larger impurity enters the crusher, the movable crushing roller 2 will be pushed away by the interaction force due to the resistance. This causes the overturning mechanism to rotate in the direction that overcomes the elastic force of the elastic mechanism, thereby increasing the distance between the crushing rollers 2. At this time, the impurity can pass between the two crushing rollers 2. In this way, when the crushing roller 2 encounters a harder and larger impurity, it can allow it to pass through, preventing the crusher from being damaged and protecting the equipment.
[0035] Two sets of elastic mechanisms are provided, one at each end of the tilting frame 3. By providing two sets of elastic mechanisms, the force on both ends of the tilting frame 3 is made uniform.
[0036] The elastic mechanism includes a spring 4 and a support rod 5. The spring 4 is sleeved on the support rod 5. One end of the support rod 5 is rotatably connected to the tilting frame 3, and the other end of the support rod 5 is rotatably and slidably connected to the frame 1 through a connecting mechanism. The two ends of the spring 4 abut against the support rod 5 and the connecting mechanism, respectively. The support rod 5 and the connecting mechanism limit the position of the spring 4, so that the position of the spring 4 can be fixed between the tilting frame 3 and the frame 1. When the tilting frame 3 rotates, the support rod 5 will rotate and slide simultaneously, causing the spring 4 to deform and generate elastic force, so that impurities can be reset after passing through the tilting frame 3.
[0037] The connecting mechanism includes a rotating rod 6 and two connecting seats 7, both of which are connected to the frame 1. Both ends of the rotating rod 6 are rotatably connected to the two connecting seats 7 respectively. One end of the support rod 5 passes through the rotating rod 6, and the support rod 5 is slidably connected to the rotating rod 6. Through the slidable connection between the support rod 5 and the rotating rod 6, the support rod 5 can only slide along its length. Simultaneously, through the rotatable connection between the rotating rod 6 and the connecting seats 7, the support rod 5 can be rotated, achieving the desired effect of the connecting mechanism.
[0038] Both connecting seats 7 are slidably connected to the frame 1 via a sliding mechanism. The end of the support rod 5 is threaded with an adjusting nut 8 for adjusting the compression of the spring 4. The adjusting nut 8 allows adjustment of the compression of the spring 4, thereby adjusting the resistance required for the crushing roller 2 to rotate. Simultaneously, the sliding range of the support rod 5 changes during adjustment, altering the distance between the two crushing rollers 2, thus adjusting the particle size of the crusher output. The connecting seats 7 can change position via the sliding mechanism, further increasing the adjustment range.
[0039] The sliding mechanism includes a limit bolt 9 and a limit nut 10. The frame 1 has a slide rail 11. The limit bolt 9 passes through the connecting seat 7 and the slide rail 11. The limit nut 10 is threadedly connected to the limit bolt 9 and abuts against the frame 1. By utilizing the mutual engagement of the limit nut 10 and the limit bolt 9, the connecting seat 7 can be pressed tightly onto the frame 1, thereby fixing its position. After loosening the limit nut 10, the connecting seat 7 can slide along the slide rail 11 under the limit of the limit bolt 9, thus achieving adjustment.
[0040] The two crushing rollers 2 are driven by two motors 12, one of which is fixedly connected to the tilting frame 3, and the other is fixedly connected to the frame 1. By driving the two crushing rollers 2 individually at the same time, the crushing force is ensured.
[0041] Both motors 12 are connected to the crushing roller 2 via a reduction gearbox 13. The reduction gearbox 13 allows for adjustment of the torque output of the motors 12 to suit the operation of the crusher.
[0042] A hopper 14 is provided on the top of the frame 1. The hopper 14 can be used to guide the material between the two crushing rollers 2.
[0043] It should be noted that many specific details have been set forth in the above description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
