Worked in field, and weeds are numerous in field, traditional oil sealing is easy to twine the situation of grass, more have impact on the close of oil sealing
Sealing property and service life.
Therefore, inventor of the present utility model needs a kind of new technology of design badly to improve its problem.
Utility model content
The purpose of this utility model is the deficiency for solving above-mentioned prior art presence there is provided a kind of oil sealing and rice transplanter,
Reasonable in design, can effectively prevent dirt, and the debris such as weeds enters oil sealing, and prevent to twine the situation of grass, significantly
Degree improves the wheel drive case life-span.
In order to solve the above technical problems, the technical solution of the utility model is as follows：
A kind of oil sealing, including：Outside body and inferior body, wherein the axial section of described outside body is L-shaped；Institute
The inferior body top axial section stated is in horizontal " one " shape, and " one " shape extends upward spacing close to one end of outside body
Projection, " one " shape horizontal surface extends downwardly out the horizontal plane of main lip, secondary lip and anti-lip care, main lip and secondary lip and outside body
Contact, anti-lip care contacts composition labyrinth structure with the vertical plane of outside body.
Further, described outside body upper end is bent to inferior body direction, to " one " of inferior body upper end
Below shape horizontal plane.
Preferential, the part of the inside side body direction bending in described its upper end of outside body is circular arc chamfering.
Described anti-lip care is at least 1.
Described main lip is located on the horizontal plane of outside body by fastening annulus hoop.
It is preferred that, described fastening annulus is spring.
Angle between described main lip and secondary lip is between 90 degree to 110 degree.
A kind of rice transplanter, with above-mentioned oil sealing.
Described oil sealing is acted against by the spacing preiection of inferior body on the outer surface of rice transplanter transmission case body, and axle is spacing
The mode that mechanism fixes outside body carries out axial restraint；The horizontal surface of outside body is contacted with axletree surface, and
Logical fastening annulus carries out radially fixed.
Using above-mentioned technical proposal, the utility model at least includes following beneficial effect：
A kind of oil sealing and rice transplanter described in the utility model, main lip and secondary lip are contacted with the horizontal plane of outside body, are prevented
Lip care contacts composition labyrinth structure with the vertical plane of outside body, forms sealing, can effectively prevent dirt and debris from entering,
Good dustproof effect, and have prevents oil sealing from twining the effect of grass well, and the wheel drive case life-span is greatly improved.
Brief description of the drawings
Fig. 1 is a kind of axial cross section structural representation of oil sealing described in the utility model；
Fig. 2 is the cross section structure schematic diagram that rice transplanter oil sealing is installed.
Wherein：1. inferior body, 1-1. inferior bodies upper end, 2. outside bodies, 3. main lips, 4. secondary lips, 5. anti-lip care, 6.
Fasten annulus, 7. spacing preiections, 8. axletrees, 9. transmission case bodies, 10. axle position-limit mechanisms.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe.
A kind of oil sealing of the present embodiment refers to Fig. 1, including：Outside body 2 and inferior body 1, wherein described outside sheet
The axial section of body 2 is L-shaped；The axial sections of described inferior body upper end 1-1 are in horizontal " one " shape, and " one " shape is close to outside
One end of body 2 extends upward spacing preiection 7, and " one " shape horizontal surface extends downwardly out main lip 3, secondary lip 4 and anti-lip care
5, main lip 3 and secondary lip 4 are contacted with the horizontal plane of outside body 2, and anti-lip care 5 contacts composition labyrinth with the vertical plane of outside body 2
Structure, this structure can effectively prevent dirt and debris from entering, good dustproof effect.
Further prioritization scheme is, described anti-lip care 5 is more than two panels or two panels, vertical with outside body 2
The multiple labyrinth cavitys of face contact composition, make the effect for preventing dirt and debris from entering more preferable.
Further, the described upper end of outside body 2 is bent to the direction of inferior body 1, to inferior body upper end 1-1's
Below " one " shape horizontal plane, so can effectively prevent from twining the phenomenon of grass, preferred scheme be described outside body 2 thereon
End is circular arc chamfering to the part that the direction of inferior body 1 is bent, and the effect of such grass-winding proof is more obvious.
The main lip 3 of oil sealing is located on the horizontal plane of outside body 2 by fastening the hoop of annulus 6, and described fastening annulus 6 is preferred
For spring.
Shape is at a certain angle between the main lip 3 of oil sealing and secondary lip 4, provides more preferable radial support for oil sealing, preferably
Angle is between 90 degree to 110 degree.
A kind of reference Fig. 2 of rice transplanter of the present embodiment, with a kind of oil sealing, goes on various rice transplanters, such as
Hand steered step transplanter, saddle type rice transplanter, high-speed transplanter etc.；The spacing preiection 7 that described oil sealing passes through inferior body 1
On the outer surface for acting against rice transplanter transmission case body 9, the mode that axle position-limit mechanism 10 fixes outside body 2 carries out axial restraint；
The horizontal surface of outside body 2 is contacted with the surface of axletree 8, and logical fastening annulus 6 carry out it is radially fixed.
Obviously, described embodiment is only a part of embodiment of the utility model, rather than whole embodiments.Base
Embodiment in the utility model, the institute that those of ordinary skill in the art are obtained under the premise of creative work is not made
There is other embodiment, belong to the scope of the utility model protection.
