Abstract
A gapless sealing structure of a rotary body of a crushing sand making machine is provided with an upper rotary body 11, a middle rotary body 12 and a bottom rotary body 13, wherein the upper rotary body 11 comprises an upper hammer body 2 and an upper hammer head 3, the upper hammer body 2 is arranged on a rotary shaft, and the upper hammer head 3 is arranged on the upper hammer body 2; at least one ring of groove 4 is arranged on the upper part of the periphery of the middle layer rotating body 12 and the bottom layer rotating body 13, and a sealing ring 5 is arranged in the groove 4. The utility model discloses owing to adopt as above design, can effectually prevent that the dust from getting into broken system sand machine, prolonged the life of pivot bearing greatly, overcome broken system sand machine multilayer rotator and unsealed lead to pivot bearing rapid wear and tear and produce vibrations and noise etc. to the problem each other, can prolong broken system sand machine's life, be favorable to operating personnel's physical and mental health, effectively avoid the emergence of incident.
Description
Technical Field
The utility model relates to a broken system sand device, especially a broken system sand machine rotator zero clearance seal structure.
Background
According to the condition analysis of the industry, the crushing sand making machine for crushing the massive stones into the fine stones has good development trend at present, and becomes a traditional and brand-new business creation field at home and abroad. China has abundant mountain stone resources, provides sufficient raw materials for the production of artificial sand, and along with the integration and adjustment of the mine industry, the crushing sand making machine exerts excellent advantages under the fumigation of the environment, but some problems generated in the production, such as that the crushing sand making equipment shows backward and seriously wastes resources, bring great obstacles to the progress of the sand and stone industry. Therefore, the development of the industry tends to be high-end and high-efficiency sand making machine. At present, real estate in China is developed quickly, and projects such as western large development, middle rising and the like are developed comprehensively, so that good development opportunities are provided for the crushing sand making machine industry in future, the crushing sand making machine has very large market demand regardless of domestic and foreign countries, and the prospect is bright.
All be equipped with the multilayer rotator on the broken system sand machine of current, the rotator includes pivot, hammer block and tup, and the hammer block is installed in the pivot, and the tup is installed on the hammer block, and the multilayer rotator is left the clearance that differs in width because unsealed each other. And broken sand making machine during operation can produce a large amount of dusts, and the dust is inevitable can be from the clearance between the multilayer rotator, enters into the pivot bearing in broken sand making machine, leads to pivot bearing rapid wear and tear and produce vibrations and noise, not only can shorten broken sand making machine's life, still can seriously influence operating personnel's physical and mental health, serious still lead to the emergence of incident easily.
Disclosure of Invention
The utility model aims at providing a broken system sand machine rotator zero clearance seal structure to solve broken system sand machine multilayer rotator and do not seal each other and lead to pivot bearing rapid wear and tear and produce vibrations and noise, shorten broken system sand machine life's problem.
The technical scheme of the utility model is that: a gapless sealing structure of a rotary body of a crushing sand making machine is provided with a multi-layer rotary body, wherein the rotary body comprises a hammer body and a hammer head, the hammer body is arranged on a rotary shaft, and the hammer head is arranged on the hammer body; the upper part of the periphery of the lower layer rotating body is provided with at least one ring of groove, and a sealing ring is arranged in the groove.
The utility model discloses further technical scheme is: the rotary sealing device is provided with an upper layer rotary body, a middle layer rotary body and a bottom layer rotary body, wherein the upper parts of the peripheries of the middle layer rotary body and the bottom layer rotary body are provided with at least one ring of groove, and a sealing ring is arranged in the groove.
The utility model discloses owing to adopt as above design, can effectually prevent that the dust from getting into broken system sand machine, prolonged the life of pivot bearing greatly, overcome broken system sand machine multilayer rotator and unsealed lead to pivot bearing rapid wear and tear and produce vibrations and noise etc. to the problem each other, can prolong broken system sand machine's life, be favorable to operating personnel's physical and mental health, effectively avoid the emergence of incident.
The invention is further described below with reference to the figures and examples.
