Problems solved by technology

[0002] The broken tooth plate is a vulnerable part. The working environment of the broken tooth plate is harsh and often needs to be replaced. The tooth nails used in the existing tooth plate are integrally cast with the base plate. Once damaged, the tooth plate needs to be replaced as a whole. Waste of resources, because the broken tooth plate is generally made of high-chromium wear-resistant cast iron, the price is relatively expensive, if the tooth plate parts are completely discarded due to local damage, the economy is not good, and the RAP recycled from different asphalt roads It is not the same. If a single tooth plate is used to crush RAP of different surfaces, sometimes the single-shaped tooth plate cannot achieve the expected effect. For example, the RAP particle size of the asphalt pavement base is generally large. In the case of the original gradation, when crushing, it is required that the possibility of crushing the original gradation is greatly reduced, so that a good crushing effect can be obtained. If the crushed RAP of the asphalt pavement layer, due to the RAP gradation of the surface layer The particle size is small, and contains fine powder particles, and the asphalt content is high. When crushing, it is required to knead and tear the asphalt adhesive phase as much as possible. Broken, will not crush RAP, thereby reducing ash and avoiding dust pollution

Embodiment 1

[0061] In the first embodiment, the locking mechanism 4 includes two card slots 41, two card blocks 42 and a spring 43, and the two card slots 41 are symmetrically arranged in the installation hole 211; , the connection part 222 is provided with a relief hole 223, the relief hole 223 is arranged perpendicular to the connection part 222, the two blocks 42 are arranged in the relief hole 223, and can move in a direction close to or away from the card groove 41; the spring 43 is arranged on Between the two blocks 42, located in the relief hole 223, the two ends are respectively connected with the two blocks 42 to drive the two blocks 42 to move close to or away from the slot 41. When the crushing teeth 22 are installed, press the two blocks 42 to make the two The block 42 is completely placed in the mounting hole 211, and the connecting portion 222 is pushed into the mounting hole 211. When the block 42 reaches the position of the slot 41, the two blocks 42 are not blocked by the ...

Embodiment 2

[0062] In the second embodiment, the mounting hole 211 is a circular hole, the connecting portion 222 is a cylinder, the locking mechanism 4 includes a circlip 44 for the shaft, and the connecting portion 222 includes an extension section 224 that can extend out of the mounting hole 211, and the shaft is used for The circlip 44 is used in conjunction with the protruding section 224 of the connecting part 222 to fix the crushing tooth 22 on the bottom plate 21. The diameter of the inner ring of the circlip 44 for the shaft is smaller than the diameter of the connecting part 222 in a natural state. Specifically, The side of the bottom plate 21 in contact with the roller body 1 is provided with a groove 212 communicating with the mounting hole 211, the extension section 224 of the connecting part 222 protrudes from the mounting hole 211 and extends into the groove 212, and the shaft is provided with a circlip 44 in the groove 212 is used in conjunction with the extension section 2...

Embodiment 3

[0063] In the third embodiment, the mounting hole 211 is a circular hole, the connecting portion 222 is a cylinder, and the locking mechanism 4 includes an expansion sleeve 45, and the expansion sleeve 45 is arranged between the mounting hole 211 and the connecting portion 222, and is connected to the mounting hole 211 and the connecting portion 222. The parts 222 cooperate with each other to fix the crushing teeth 22 on the bottom plate 21. When installing the crushing teeth 22, push the expansion sleeve 45 into the installation hole 211 first, and then push the connecting part 222 into the expansion sleeve 45 to realize the crushing teeth 22. Install.

Abstract

Disclosed are a crushing roller and an arrangement and combination method of crushing teeth of the crushing roller. The crushing roller includes a roller body and multiple tooth plates detachably arranged on the roller body. Each tooth plate includes a bottom plate and multiple crushing teeth detachably arranged on the bottom plate. Each bottom plate is provided with multiple mounting holes used for mounting the crushing teeth. Each crushing tooth includes a working part and a connecting part capable of being embedded into the corresponding mounting hole. A locking mechanism is arranged between each connecting part and the corresponding mounting hole. The crushing teeth are detachably arranged on the bottom plates through the cooperation of the mounting holes, connecting parts and lockingmechanisms. When the crushing teeth are damaged, only the damaged crushing teeth are replaced without replacing the whole tooth plate or replacing the whole crushing roller, thereby greatly reducing the use cost, reducing resource waste, and ensuring the crushing of a recycled asphalt mixuture.
