Abstract

The utility model discloses a rotary tiller shaft bearing frame is with novel dustproof sealing device, including arbor spindle nose, bearing, bearing frame, double oil seal, pedestal cap, grease nipple, dustproof case, nylon dust ring and jump ring, the dustproof case suit in outer and the fixed connection of arbor spindle nose, the cross -section of bearing frame is provided with the recess, dustproof case's the protruding card of a terminal surface is gone into in the recess of bearing frame, nylon dust ring suit in outside the dustproof case, and lie in the bearing frame with between the dustproof case, the jump ring connect in the nylon dust ring with between the bearing frame. Compared with the prior art, the utility model discloses a dustproof case rotates with the arbor spindle nose together, and the bearing frame passes through the jump ring with the nylon dust ring to be fixed, and the dustproof case of Z type forms sealedly with the recess of bearing frame to reach multiple sealed effect, the effectual impouring that prevents mud has the value of using widely.

Description

Rotavator knife bearing housing Dustproof sealing device

Technical field

The utility model is related to a kind of mechanical seal structure, more particularly to a kind of rotavator knife bearing housing Dustproof Sealing device.

Background technology

Rotary cultivator is the cultivation machinery for completing to plough, harrow operation with tractor.Because it has, hack ability is strong, plough rear ground The features such as table is flat, and be widely used；The root stubble being embedded in below earth's surface can be shredded simultaneously, be easy to seeder to make Industry, for later stage sowing provides good kind bed.Proper use of and adjustment rotary cultivator, to keeping its good technique state, it is ensured that farming Quality is critically important.In the prior art, the cutter shaft of rotary cultivator needs rotation, and cutter shaft works in soil environment, bearing connection Place be easily accessible dust, cause to run out bearing, bearing service life is low, there is room for improvement.

Utility model content

The purpose of this utility model is that and provided to solve the above problems a kind of rotavator knife bearing housing with newly Type dust-proof sealing device.

The utility model is achieved through the following technical solutions above-mentioned purpose：

The utility model includes cutter shaft spindle nose, bearing, bearing block, double oil seal, pedestal cap, grease nipple, dustproof shell, nylon Dust ring and jump ring, the dustproof shell are set in outside the cutter shaft spindle nose and are fixedly connected, and the section of the bearing block is provided with Groove, the end face projection of the dustproof shell is snapped in the groove of the bearing block, and the nylon dust ring is set in described anti- Outside dirt shell, and between the bearing block and the dustproof shell, the jump ring is connected to the nylon dust ring and the axle Between bearing.

Specifically, the nylon dust ring is taper；The section of the dustproof shell is " Z " type, the dust-proof housing and institute State spot-welded connection between cutter shaft spindle nose.

The beneficial effects of the utility model are：

The utility model is a kind of rotavator knife bearing housing Dustproof sealing device, compared with prior art, this The dustproof shell of utility model is rotated together with cutter shaft spindle nose, and bearing block is fixed with nylon dust ring by jump ring, the dustproof shell of Z-type Groove with bearing block forms sealing, so as to reach multi-sealed effect, effectively prevents being poured into for mud, makes with popularization Value.
