The lower part of glue seal fits, and PTFE pair lips are provided on sheet of PTFE；The bottom of the outside framework oil seal is provided with metal case,
It is by the metallic framework extending part inside rubbery sealed body that the main body of metal case, sheet of PTFE and rubbery sealed body is combined
Connection.
Optionally, metallic framework is profiled metal skeleton.
Optionally, metallic framework includes two lateral parts, the left ends of two lateral parts respectively with longitudinal bending part
Lower end be connected.
Optionally, two lateral parts of metallic framework are parallel.
Optionally, the right end of the lateral part below metal case is provided with the angle bending part of " L " font.
Optionally, the vertical section of angle bending part is set as incline structure.
Optionally, the vertical section of angle bending part tilts down from left to right.
Optionally, PTFE pairs lip tilts down from left to right.
The utility model has the following advantages that：
The farm machinery outside framework oil seal of the utility model, the used environment that can solve agricultural vehicle bridge are extremely disliked
Bad, dust storm is big and superfine, and sand-dust impurity is easily doped into common oil sealing, leads to the major and minor lip abrasion of oil sealing, causes asking for oil leak
Topic, can stop the sand-dust impurity of bulky grain, can effectively stop that superfine sand and dust enter inside oil sealing, are effectively protected pair
Lip and main lip prevent the superfine sand and dust under adverse circumstances from entering oil sealing internal sabotage lip and cause oil leak；It can adapt in pole
Hold boisterous applying working condition.
Description of the drawings
Fig. 1 is the structural schematic diagram of the farm machinery outside framework oil seal of the utility model.
In figure, 1 is metallic framework, and 2 be spring, and 3 be primary seal lip, and 4 be rubbery sealed body, and 5 be secondary sealing lip, and 6 be rubber
Glue lip, 7 be sheet of PTFE, and 8 be metal case, and 9 be PTFE pair lips.
Specific implementation mode
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.
Embodiment
It is close to be provided with rubber referring to Fig. 1, including metallic framework 1, on metallic framework 1 for a kind of farm machinery outside framework oil seal
Body 4 is sealed, spring 2 is provided in rubbery sealed body 4, there are one primary seal lip 3, rubber seals for the top setting of rubbery sealed body 4
There are one the rubber lip 6 of secondary sealing lip 5 and a support sheet of PTFE 7, sheet of PTFE 7 and rubbery sealed bodies 4 for the lower part setting of body 4
Lower part fit, PTFE pairs lip 9 is provided on sheet of PTFE 7；The bottom of the outside framework oil seal is provided with metal case 8, passes through
1 extending part of metallic framework inside rubbery sealed body 4 is by the main body phase group of metal case 8, sheet of PTFE 7 and rubbery sealed body 4
Close connection.
As it can be seen that the farm machinery outside framework oil seal of the present embodiment, metal case 8 can stop that the sand and dust of bulky grain are miscellaneous
Matter, PTFE pairs lip 9 can effectively stop that superfine sand and dust enter inside oil sealing, combination structure, coordinate other structures energy
It is enough effectively protected secondary lip and main lip, is adapted to the applying working condition of exceedingly odious weather, is prevented superfine under adverse circumstances
Sand and dust enter oil sealing internal sabotage lip and cause oil leak.
The farm machinery outside framework oil seal of the utility model can further include such as lower structure, and metallic framework 1 is different
Shape metallic framework.Metallic framework 1 includes two lateral parts, the left ends of two lateral parts respectively under longitudinal bending part
