Quality is critically important.In prior art, the cutter shaft of rotary cultivator needs to rotate, and cutter shaft works in earth environment, and bearing connects
Place be easily accessible dust, cause running out bearing, bearing is low for service life, there is room for improvement.
Utility model content
The purpose of this utility model is that provides a kind of rotavator knife bearing housing with many to solve the problems referred to above
Repeat to close dust-proof sealing device.
This utility model is achieved through the following technical solutions above-mentioned purpose:
This utility model includes cutter shaft spindle nose, bearing, bearing block, double oil seal, pedestal cap, grease nipple, dustproof shell, dust-proof
Including sheet, dust cap and fixing bolt, described dustproof shell is set on the cylindrical of described cutter shaft spindle nose and fixing connection, described dust-proof
The middle part of shell is provided with groove, and the described dust-proof sheet that includes is positioned at the groove of described dustproof shell, described dustproof shell and described dust-proof include
Sheet is all coated in described bearing block, and described dust cap is arranged between described dustproof shell and described bearing block, and by described
Fixing bolt is fixing to be connected.
Further, the described dust-proof sheet that includes is two semi-annular shape structures, point between described dust cap and described cutter shaft spindle nose
Weldering is welded to connect.
The beneficial effects of the utility model are:
This utility model is a kind of rotavator knife bearing housing MULTIPLE COMPOSITE dust-proof sealing device, with prior art phase
Ratio, this utility model arranges the dust-proof sheet that includes of two semicircles, and two panels is circular altogether, cutter shaft rotates when, centrifugal force
Effect under, two include sheet and can closely cooperate with bearing block, reach dust-proof effect such that it is able to improve bearing the use longevity
Life, reduces maintenance probability, has the value of popularization and application.
