Abstract
The utility model discloses a leakage-proof device for an auger. The leakage-proof device comprises a spring and two oil seal seats fixedly arranged at the two ends of the spring; two oil seals different in inner diameter are mounted on each oil seal seat; a shell is arranged to enclose the oil seal seats. The leakage-proof device has the advantages that the oil seal larger in inner diameter is used for sealing the shaft hole of the auger, while the oil seal smaller in diameter is used for sealing the shaft of the auger, and therefore, the dual-sealing effect is achieved.
Description
Technical field
The utility model relates to a kind of leak-proof device for auger.
Background technology
Auger is being commonly called as of conveyor screw, is applicable to the horizontal feed of particle or granular material, tilts to carry the forms such as vertical transport.The auger of prior art is in convey materials process, and because sealing effectiveness is not good, material easily leaks in twisted axis, can produce damage to twisted axis.
Utility model content
The purpose of this utility model is to provide a kind of leak-proof device for auger, to solve the existing the problems referred to above of prior art.
To achieve these goals, the technical solution of the utility model is as follows:
For a leak-proof device for auger, it comprises: spring and two oil seal seats that are installed in the two ends of described spring, be provided with two different oil sealings of internal diameter, the outer shell that is arranged with of oil seal seat on described oil seal seat.
As preferred version, described oil sealing is Y shape oil sealing.
As preferred version, described shell middle part is provided with oil hole.
As preferred version, described oil hole is unidirectional oil hole.
The utility model has the advantage of, utilize and compared with the oil sealing of large diameter, auger axis hole is sealed, utilize the oil sealing of small diameter to seal screw-conveyer-shaft, reached the effect of double seal.
?
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1, shell; 11, unidirectional oil hole; 2, spring; 31, the first oil seal seat; 32, the second oil seal seat; 41, the first oil sealing; 42, the second oil sealing; 43, the 3rd oil sealing; 44 the 4th oil sealings.
The specific embodiment
Referring to accompanying drawing 1, shell 1 inside with unidirectional oil hole 11 is provided with spring 2, the two ends of spring 2 are separately installed with the first oil seal seat 31 and the second oil seal seat 32, the first oil seal seat 31 is provided with the first oil sealing 41 and the second oil sealing 42, the second oil seal seat 32 is provided with the 3rd oil sealing 43 and the 4th oil sealing 44, wherein, the internal diameter of the first oil sealing 41 is greater than the internal diameter of the second oil sealing 42, the internal diameter of the 3rd oil sealing 43 is greater than the internal diameter of the 4th oil sealing 44, and the first oil sealing 41, the second oil sealing 42, the 3rd oil sealing 43 and the 4th oil sealing 44 are Y shape oil sealing.
During use, utilize oil pump by unidirectional oil hole 11 to the interior injection lubricating oil of shell 1, by the flexible of spring 2, lubricating oil is diffused in whole shell, the stretching, extension of spring 2 is supported on auger inside by the first oil seal seat 31 and the second oil seal seat 32, the first oil sealing 41 and 43 pairs of axis holes of the 3rd oil sealing seal, the second oil sealing 42 and 44 pairs of screw-conveyer-shafts of the 4th oil sealing seal, and meanwhile, the lubricating oil in shell 1 also has oil-tightening effect concurrently.
To sum up, the utility model has the advantage of, utilize and compared with the oil sealing of large diameter, auger axis hole is sealed, utilize the oil sealing of small diameter to seal screw-conveyer-shaft, reached the effect of double seal.
In sum, it is only preferred embodiment of the present utility model, not be used for limiting the scope that the utility model is implemented, all equalizations of doing according to the shape described in the utility model claim scope, structure, feature and spirit change and modify, and all should be included within the scope of claim of the present utility model.
