Abstract
The utility model discloses a prevent multistage telescopic cylinder of ash dust removal, including the cylinder body, cylinder body bottom has recovery cylinder, and cylinder body cylinder junctions at different levels all are equipped with a dustproof cap, and dustproof cap and the cylinder fixed connection of subordinate are with higher level's cylinder sliding connection, recovery cylinder bottom undercut becomes the obconic form, and recovery cylinder bottom center is equipped with the bleeder valve, is equipped with supplementary admission valve on the casing wall of recovery cylinder bottom one side. The utility model discloses a set up the dustproof cap in cylinder junctions at different levels, prevent effectively that the dust from getting into the cylinder in, reduced the grey dust quantity that gets into the cylinder greatly, become the obconic shape through cylinder bottom undercut to being equipped with bleeder valve and supplementary admission valve in cylinder bottom, thoroughly eliminating cylinder bottom dust, the maximize reduces in the jar dust to the harmful effects of cylinder, the life of extension cylinder.
Description
Technical field
This utility model belongs to technical field of mechanical automation, relates to a kind of telescopic cylinder, specifically a kind of anti-
The multi-stage expansion cylinder of ash dedusting.
Background technology
Multi-stage expansion cylinder is often used as the elevating mechanism in automation equipment, but automation equipment works
During be easily generated the particulate matters such as chip, most particulate matters and the dust in external environment are in the mistake accumulated over a long period
Cheng Zhonghui is attached on external diameter of cylinder, and these particulate matters can be brought in cylinder when cylinder declines, minority dust
Can be directly entered in cylinder, causing rubs during cylinder moving increases, and causes heating, if not clearing up for a long time,
The stroke accuracy of cylinder can be have impact on, reduce the service life of cylinder.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, easy to operate, the multistage of anti-gray dedusting to stretch
Contracting cylinder.
The purpose of this utility model can be achieved through the following technical solutions:
The multi-stage expansion cylinder of a kind of anti-gray dedusting, including cylinder body, has bottom described cylinder body
Reclaiming cylinder, described cylinder body cylinder at different levels junction is equipped with a dust cap, described dust cap
Fixing with subordinate cylinder it is connected, is connected with higher level's cylinder slide；
Described recovery cylinder bottom concave downward becomes inverted conical shape, described recovery cylinder end center to set
Extraction valve, described recovery cylinder bottom side casing wall is had to be provided with additional-air inlet valve.
Further, described dust cap has the extension downwardly extended.
Further, described dust cap is conical by its shape.
The beneficial effects of the utility model: this utility model by arranging dust cap in cylinder junctions at different levels,
Effectively prevent dust from entering in cylinder, substantially reduce the amount of dust entering cylinder, downward by cylinder end
Cave in into turbination shape, and be provided with extraction valve and additional-air inlet valve in cylinder bottom, thoroughly by the bottom of cylinder
End dust is removed, and maximizes and reduces the dust harmful effect to cylinder in cylinder, extends the service life of cylinder.
Accompanying drawing explanation
With specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is this utility model structural representation.
In figure: 1-cylinder body；2-reclaims cylinder；3-air valve mouth；4-dust cap；5-extension；
6-extraction valve；7-additional-air inlet valve.
Detailed description of the invention
As it is shown in figure 1, this utility model provides the multi-stage expansion cylinder of a kind of anti-gray dedusting, including cylinder
Body 1, has recovery cylinder 2 bottom cylinder body 1, reclaim and have air valve mouth 3 bottom cylinder 2,
For controlling the flexible of multi-stage expansion cylinder.
Being positioned at cylinder body 1 cylinder at different levels junction and be equipped with a dust cap 4, dust cap 4 uses rubber material
Material is made, good sealing effect, is effectively reduced dust and enters in cylinder.
Fixing with subordinate cylinder casing wall bottom dust cap 4 being connected, dust cap 4 uses conical by its shape, and it is with upper
Level cylinder slide connects, when cylinder declines, and can be miscellaneous with bulky grain by the part dust on higher level's external diameter of cylinder
Thing scrapes, and greatly reduces the amount of dust entering cylinder.
Dust cap 4 has the extension 5 downwardly extended, and extension 5 covers the connecting portion of upper and lower level cylinder,
Reduce the amount of dust entering cylinder further.
Reclaim concave downward bottom cylinder 2 and become inverted conical shape, make dust be easier to be deposited in cylinder bottom
The heart.Being positioned at recovery cylinder 2 bottom center and be provided with extraction valve 6, extraction valve 6 is positioned at air valve side.It is positioned at
Reclaim cylinder 2 bottom side casing wall and be provided with additional-air inlet valve 7, when extraction valve 6 is opened and bled, open auxiliary
Help intake valve 7 can supplement air and enter recovery cylinder 2, form air-flow, the dust of cylinder end is removed,
Reduce to bigization the harmful effect to cylinder of the cylinder interior dust.
This utility model, by arranging dust cap in cylinder junctions at different levels, effectively prevents dust from entering in cylinder,
Substantially reduce the amount of dust entering cylinder, by becoming turbination shape at cylinder end concave downward, and
It is provided with extraction valve and additional-air inlet valve in cylinder bottom, thoroughly cylinder end dust is removed, maximize and reduce
The dust harmful effect to cylinder in cylinder, extends the service life of cylinder.
Above content is only to this utility model structure example and explanation, affiliated the art
Described specific embodiment is made various amendment or supplements or use similar mode to replace by technical staff
In generation, without departing from the structure of utility model or surmount scope defined in the claims, all should belong to
In protection domain of the present utility model.
