Need not be by attendant's manually mobile security pin.Guarantee to forget safety catch by the automatic motion of safety stop lever
Bar puts back to its job position and no correct safety measure just starts again at job run.Thus, according to the present invention, make institute
The position for stating coupling device safety stop lever forces to associate with scraper, particularly scraper plate physical location at least in part,
So that the position of scraper is via the prespecified position of safety stop lever of the coupling device.Thus, by the structure
Make, coupling device can realize automatic function on the position of safety stop lever, ensure that, safety stop lever is for maintenance purpose
And corresponding desired position is had according to the positioning of the scraper in job run.The coupling device is therefore total
It is configured on body so that safety stop lever automatically and according to the positioning of scraper converts which in maintenance position and job position
Between relevant position.
In this regard, the coupling device is suitably configured to so that the coupling device is in scraper in high position
When safety stop lever is locked in maintenance position.If safety stop lever is stably maintained in its maintenance position, there is locking,
So that it is guaranteed that the safety stop lever will not uncontrollably fall back to its job position.This is preferably accomplished by, i.e.,
The coupling device is used as holding meanss simultaneously.
In order to implement the present invention as simply as possible, the coupling device is configured to so that the coupling device is by scraper
The regulation motion of device, the regulation conversion of motion particularly from its lower position to its high position are safety stop lever from job position
To the motion of maintenance position.In this regard, in order to constitute the coupling device, can adopt various operational in machinery
Force transfering device.The coupling device therefore, it is possible to by the motion of scraper hydraulically or electrically, it is but particularly purely mechanic
It is delivered in safety stop lever likes.The salient point of purely mechanic power transmission particularly in, it is not necessary to extra energy source makes peace
Full pin motion.
It is particularly preferred that the coupling device is the guide transmission device for making safety stop lever move along planned orbit.It is logical
The track of prespecified safety stop lever is crossed, particularly be ensure that, on the one hand guarantee to realize the phase in the job position of safety stop lever
The personnel protection of prestige, and on the other hand, in safety stop lever in maintenance position, milling roller box cavity can be freely accessible to.In advance
Fixed track here had both represented the direction of motion of safety stop lever, also illustrated that safety stop lever is directed the section moved along it.
Substantially, can move safety stop lever by any-mode.It is as much as possible for upkeep operation in order to obtain
Space, it is advantageous to which coupling device is achieved in that, i.e. make the linear motion of scraper be converted into the swing of safety stop lever
Motion, especially towards the oscillating motion of ground milling machine.By the hinge in frame of the safety stop lever by road milling machine
To the swing of at least partly vertical position or motion is stirred from level around rotation axiss, in operating direction after milling roller case
The free space obtained in the region in face is significantly more than the situation of the still simple altitude mixture control of horizontally disposed safety stop lever.
The rotation axiss of this safety stop lever are preferably parallel to the rotation axiss of ground milling machine and extend.
The transmission of motion generally can be by coupling device via any connecting element, such as rope, particularly cable wire, chain
Or similar connecting elements are realized.Coupling device preferably comprises lever, particularly draw bar, and the lever will be moved from scraper
Safety stop lever is delivered to, thus coupling device has particularly simple structure.Reliable motion transmission ensure that by lever.For
This lever can be supported to linear movement an end, and is swingably supported in another end.By such arrangement shape
Formula particularly simply realizes the conversion of the oscillating motion for being linearly moved to safety stop lever of scraper.For this purpose, the lever
It is preferred that be hingedly attached on safety lever in side, and opposite side be hingedly attached to ground milling machine relative to frame
On the region that position is fixed, particularly it is hinged on a part of milling roller case.
During the job run of milling roller, it may be necessary to be adjusted differently than the height of scraper.This is probably for example
Following purpose is realized, i.e., the material of different amounts of loosening is left in milling bed, or is scraped in possible minimum lower position
Dynamic milling bed bottom.In scraper operation application, be adjusted to corresponding lower position is it is possible thereby to according to application purpose certain
In the range of change.Even if now in order to ensure when scraper is in different lower positions safety stop lever remain in its operation position
In putting, preferably set, coupling device is configured to so that make safety stop lever leave its operation position by the altitude mixture control of scraper
The motion put just occurs when more than the regulation boundary for determining.The regulation boundary reasonably leaves lower position positioned at scraper
Altitude mixture control region top, scraper reaches the region in normal altitude mixture control during job run.
Only when scraper is adjusted in height beyond the regulation boundary, coupling device just triggers safety stop lever from operation position
Put the regulation of maintenance position and for example the lift motions of scraper are delivered in safety stop lever for this.Thus safety stop lever
Motion also scraper reach and exceed the boundary when just generation.Reliably avoid in road milling by this way
There is the motion that safety stop lever leaves its job position during planer job run.
In order to be normally used the present invention completely, it is of special importance that the safety stop lever for leaving its maintenance position is also reliable
Be again introduced into its job position, so as to for example guarantee upkeep operation terminate and restart ground milling machine operation fortune
After row, the safety stop lever will not stay in unintentionally maintenance position.Thus, coupling device is also desirably structured to, and makes safety catch
Return movement of the bar from its maintenance position to job position is realized by gravity.This embodiment can extremely simplely, it is economical
Ground and realized with little component.Direction is adjusted to as scraper is returned from its high position when milling roller case is opened
The lower position on ground, thus allows the safety stop lever dug upwards or move upwards to decline, and this decline is especially by gravity
Realize.Therefore also without the driving means of the regulation motion individually, for making safety stop lever backtracking position.
One kind is preset to this particularly suitable embodiment, is provided with drive element on scraper, and
Backstop is provided with safety stop lever.The drive element is come in the backstop, then from following gear when scraper rises
In the continuation lift motions of scraper, safety stop lever is moved to which from its job position by the motion of backstop and safeguards position
Put.Thus, by the drive element, the motion of scraper is passed in backstop.Here, driving element gear to lean against backstop
On height adjusted position constitute adjust boundary.Machine is fixed on via hinge by the embodiment is prespecified particularly well
The motion of the safety stop lever on frame, because safety stop lever is simply by the backstop and and drives element by scraper band
It is dynamic.Regulation boundary can be limited by driving the setting being spaced apart between element and backstop, from the regulation boundary, filled in scraper
During the lift motions put, safety stop lever is moved.That is, the boundary is just reached after the interval is overcome, which sets out
Point is that the boundary is in outside the normal range of accommodation of scraper during the job run of road milling machine, and
From the boundary, scraper further adjusts the motion for causing safety stop lever to leave its job position.Here, the backstop
Need not be set directly in safety stop lever, but can also be connected with the safety stop lever via lever or other connecting elements.
By arranging chute guide so that the further precision of guiding and simplification to safety stop lever, the chute are led
To the motion of the prespecified backstop of part.This chute guide is effectively prevented backstop and skids during its motion or deviate predetermined
Track.Therefore ensure that track that safety stop lever also follows which predetermined and be not in the interference to motor process.For this purpose, institute
State chute guide and preferably include elongated hole guide part, the elongated hole guide part is with milling roller case, basic in vertically side
