Description
Technical field
The present invention relates to a kind of flusher.
Background technology
In recent years, as multi-rotor aerocraft develops, because its with maneuverability, rapid reaction, unmanned flight, operation will
Low advantage is sought, its application in multiple fields is caused, particularly in agricultural plant protection field.Sprinkling on multi-rotor aerocraft
Device is one of pith for influencing its operating efficiency.
In correlation technique, there are sealing problem between the drive shaft of flusher and installation housing, liquid be easy into
Enter actuator short circuit and the corrosion to installation enclosure interior, caused in flusher, significantly reduce the reliable of flusher
Property and service life.Conventional sealing ring e insufficient to play the role of being fully sealed, such as O-ring seal, but also can shadow
Ring the rotational efficienty to rotating member (such as drive shaft).
The content of the invention
The present invention provides a kind of flusher, it is intended to solve at least to a certain extent technical problem in correlation technique it
One.
A kind of flusher according to embodiments of the present invention, including：
Disk is sprayed, for liquid to be sprayed；
Driving device, including for providing the actuator of power to the sprinkling disk and driving its turn by the actuator
Dynamic drive shaft, the drive shaft are fixedly connected with the sprinkling disk；
Housing component, including for being fixedly mounted and storing the main casing of the actuator and extended to along the main casing
Secondary housing on the sprinkling disk, the main casing are equipped with the accommodating cavity for housing the actuator, the secondary housing be equipped with
The accommodating cavity is communicated for the via hole for drive shaft insertion；
Sealing ring, including waterproof baffle ring, the waterproof baffle ring are equipped with through the waterproof baffle ring and for being inserted into rotation axis
Through hole, the both ends of the through hole set the casing of elastically deformable, and the drive shaft passes through the through hole, described to pass through
The inner wall of through hole, the inner wall of described sleeve pipe are close to the outer surface of the drive shaft and the outer wall of the waterproof baffle ring is held in institute
State on the hole wall of via hole.
Beneficial effects of the present invention：By the way that the both ends of the through hole to be set to the casing of elastically deformable, so that perforation
Hole is in close contact with rotation axis, reduces the friction between the sealing ring and the rotation axis, in favor of the rotation axis
Rotate.
Brief description of the drawings
Fig. 1 is the structure diagram of flusher according to embodiments of the present invention.
Embodiment
The embodiment of the present invention is described below in detail, the example of the embodiment is shown in the drawings.Below with reference to
The embodiment of attached drawing description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
It is shown in Figure 1, a kind of flusher of the embodiment of the present invention, including：
Disk 1 is sprayed, for liquid to be sprayed；
Driving device, including for providing the actuator of power to the sprinkling disk and driving its turn by the actuator
Dynamic drive shaft 2, the drive shaft 2 are fixedly connected with the sprinkling disk；
Housing component 3, including for being fixedly mounted and storing the main casing of the actuator and extend along the main casing
Secondary housing to the sprinkling disk, the main casing are equipped with the accommodating cavity for housing the actuator, and the secondary housing is equipped with
Communicated with the accommodating cavity for the via hole for drive shaft insertion；
Sealing ring 4, including waterproof baffle ring, the waterproof baffle ring are equipped with through the waterproof baffle ring and for being inserted into rotation axis
Through hole, the both ends of the through hole set the casing 5 of elastically deformable, and the drive shaft passes through the through hole, described
Inner wall, the inner wall of described sleeve pipe 5 of through hole are close to the outer surface of the drive shaft and the outer wall of the waterproof baffle ring supports
In on the hole wall of the via hole.
Beneficial effects of the present invention：By the way that the both ends of the through hole to be set to the casing of elastically deformable, so that perforation
Hole is in close contact with rotation axis, reduces the friction between the sealing ring and the rotation axis, in favor of the rotation axis
Rotate.The sealing ring is arranged concentrically the waterproof protrusion to play the role of radial and axial fixation using the waterproof protrusion.
