Problems solved by technology

At present, most of the conventional crushing teeth adopt the integral casting type. The crushing teeth and the crushing tooth seat are an integral structure. After the crushing teeth are broken, they cannot be replaced separately. After wear and tear, the entire crushing tooth roller must be replaced. The maintenance volume is large, the maintenance cost is high, and it cannot be replaced on site. , seriously restricting the normal production of coal mines

Embodiment Construction

[0016] The present invention is described in detail below in conjunction with accompanying drawing and embodiment:

[0017] A crushing tooth structure of a grading crusher, see attached figure 1 to attach image 3 , In the figure: tooth seat 1, nut 2, bolt 3, broken tooth 4, limit key structure 5, circular through hole 6, square counterbore 7, hoisting through hole 8, groove structure 9.

[0018] In this embodiment, the crushing tooth 4 is connected to the tooth seat 1 through a bolt 3 , the non-threaded end of the bolt 3 is in a square structure, and the threaded end of the bolt 3 is connected to the nut 2 .

[0019] Tooth holder 1 has a wedge-shaped structure, such as figure 1 As shown in ; the connecting end of the gear seat 1 and the crushing tooth 4 is provided with a limit key structure 5; the limit key structure 5 is located on the axial symmetrical center line of the tooth seat 1; the crushing tooth 4 is provided with a limit key structure 5 matching groove structur...

Abstract

The invention relates to a classification crusher component, in particular to a classification crusher crushing tooth structure. The classification crusher crushing tooth structure comprises a tooth base and crushing teeth which are connected with the tooth base through connecting pieces. Compared with the prior art, the structure is simple, replacement is convenient, when the crushing teeth are abraded, replacement of a whole tooth roller is not needed, normal work can be recovered only by replacing the seriously-abraded crushing teeth, the accessory expense is saved, the maintenance time isshortened, and the work efficiency is improved.

Description

technical field [0001] The invention relates to a component for a graded crusher, in particular to a crushing tooth structure of a graded crushing gear machine. Background technique [0002] The crushing tooth is the core working part of the grading crusher, and its structural performance directly determines the overall performance of the equipment. In addition to coal, there are a large amount of hard materials such as gangue and sandstone mined from underground coal mines. These materials have high hardness, are not easy to break, and have serious wear and tear on the broken teeth. At present, most of the conventional crushing teeth adopt the integral casting type. The crushing teeth and the crushing tooth seat are an integral structure. After the crushing teeth are broken, they cannot be replaced separately. After wear and tear, the entire crushing tooth roller must be replaced. The maintenance volume is large, the maintenance cost is high, and it cannot be replaced on s...
