In some embodiments, the steel band hole is located at immediately below the steel belt disk, can reduce steel band during the work time
With the friction of steel band catch.
In some embodiments, the through hole is to be bolted with the steel band catch.
In some embodiments, the steel band catch is circle.
In some embodiments, the air admission hole is arranged at the upper limit device orlop portion.
In some embodiments, the air admission hole is screw hole so that it is convenient for disassembly and assembly with extraneous air generating means, it is effectively anti-
Only air is revealed.
In some embodiments, the air admission hole is connected with external compressed air generator.
The beneficial effects of the utility model are：Probe is added into a upper limit device storehouse, and with partition plate by steel band storehouse with it is upper
Limit device storehouse separates, and a through hole is set on partition plate, steel band catch is set on through hole, can prevent work when level-sensing device works
Dust in environment enters steel band storehouse and blocks steel belt disk, is blown using positive pressure, and compressed air enters from air admission hole so that upper limit device
Storehouse keeps positive pressure, is blown out air outward by the pipeline in upper limit device, avoids dust condensation that upper limit device steel tube material is caused to coagulate
Knot blocks.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
In Fig. 1, Fig. 2, as the example one of the utility model, a kind of antifouling type weight dropper charge level indicator probe, including steel band
Disk mounting base 4 and motor bin 1 are equipped with steel belt disk in steel belt disk mounting base 4, further include probing shell, steel band storehouse 2 and upper limit device
Storehouse 3, steel band storehouse 2 are separated with upper limit device storehouse 3 by a partition plate 8, and motor bin 1, steel band storehouse 2 and upper limit device storehouse 3 are divided into probe shell
In vivo, motor bin 1 is arranged at the left end of probing shell, steel band storehouse 2 and upper limit device storehouse 3 be arranged on the right end in probing shell and from
On set down.Steel belt disk is arranged in steel band storehouse 2, and a through hole 5 is provided on partition plate 8, is passed through for the steel band of steel belt disk, the upper limit
An air admission hole 7 is additionally provided on device storehouse 3, air admission hole 7 is used for being connected to external compressed air generator.
In Fig. 3, a steel band catch 9 is further included, steel band catch 9 is arranged on through hole 5 and a steel is provided on steel band catch 9
With holes 91, the size in steel band hole 91 is adapted with steel band.The effect for setting steel band catch 9 is effectively to prevent dust from entering steel band
Storehouse 2 prevents steel band storehouse 2 from blocking, while the steel band for being also possible to prevent steel belt disk during exercise wears partition plate 8.91, steel band hole
Immediately below steel belt disk, the friction that steel band generates during the work time with steel band catch 9 can be reduced.3 are provided with around through hole 5
A mounting hole 6 also has with 6 corresponding hole of mounting hole on steel band catch 9, the mode being connected by screw bolts by steel band catch 9 with
Through hole 5 connects, the quantity of mounting hole or 2,4,5 etc., and steel band catch 9 is circle.
In Fig. 1, Fig. 3, air admission hole 7 is arranged at 3 bottom of upper limit device storehouse, and air admission hole 7 is screw hole, using threaded connection, energy
External compressed air generator is conveniently connected to, can also prevent compressed air from being revealed in junction.
As the example two of the utility model, three chambers are by the way of horizontal positioned, between steel band storehouse 2 and upper limit device storehouse 3
It is separated with partition plate, this mode can equally reach the purpose of this utility model.
The operation principle of the present embodiment is：When measurement starts, external compressed air enters upper limit device storehouse by air admission hole 7
In 3, upper limit device storehouse 3 remains positive pressure so that there is air externally to blow out always in upper limit device steel pipe, it can be effectively by environment
In dust blow away, prevent dust or material condense from blocking upper limit device, meanwhile, after part dust enters upper limit device storehouse 3, due to by
To the influence of partition plate 8 and steel band catch 9, it is impossible to enter in steel band storehouse 2, avoid because the excessively multipair steel belt disk of dust blocks.
Advantage of this embodiment is that：A upper limit device storehouse is added in probe, is divided steel band storehouse and upper limit device storehouse with partition plate
It separates, through hole on partition plate is set, steel band catch is set on through hole, the powder in working environment can be prevented when level-sensing device works
Dirt enters steel band storehouse and blocks steel belt disk, is blown using positive pressure, and compressed air enters from air admission hole, due to air admission hole and compressed air
For connector using being threadedly coupled, good airproof performance effectively avoids compressed air from revealing so that upper limit device storehouse keeps positive pressure, can be by dust
It is blown out outward from the steel pipe of upper limit device, avoids dust that the condensation of upper limit device steel tube material is excessively caused to block.
Only the most preferred embodiment of the utility model is described above, but is not to be construed as the limit to claim
System.The utility model is not only limited to above example, and concrete structure is allowed to vary.It is all in the utility model independent right
