Description
Technical field
The utility model relates to dustproof rotary ploughing cutter shaft for a kind of agricultural rotary tiller, belongs to agricultural machinery technological field.
Background technology
Agricultural rotary tiller is one of farm machinery main in agricultural production, in China's agricultural production, plays an important role.Rotary ploughing cutter shaft is the critical piece on agricultural rotary tiller, connects with speed changing box power output shaft, and rotation under power take-off drives, installs superincumbent rotary blade by soil spin-up, pulverizes.Known rotary ploughing cutter shaft is owing to there is no dust prevention, and in soil, dust is easy to enter in the bearing at cutter shaft two ends and damages bearing when operation, causes facility fault, not only affects facility operating efficiency but also increased maintenance cost.
Summary of the invention
The purpose of this utility model is to provide dustproof rotary ploughing cutter shaft for a kind of agricultural rotary tiller.
The technical solution of the utility model is: dustproof rotary ploughing cutter shaft for a kind of agricultural rotary tiller, include rotary ploughing cutter shaft central siphon, on rotary ploughing cutter shaft central siphon circumference, be welded with rotary tillage cutter holder, spindle nose and adpting flange are welded on respectively rotary ploughing cutter shaft central siphon two ends, coupling sleeve is arranged on adpting flange, on spindle nose and coupling sleeve, be welded with respectively gear soil ring, gear soil ring on spindle nose matches with the draw-in groove of side plate bearing chamber, gear soil ring on coupling sleeve matches with the draw-in groove of casing bearing chamber, and while preventing operation, dust enters in the bearing of side plate bearing chamber and casing bearing chamber.
Dustproof rotary ploughing cutter shaft for the agricultural rotary tiller that the utility model provides, rational in infrastructure, cost is low, can effectively prevent the damage of dust to bearing, has extended the service life of bearing, has greatly improved the operating efficiency of complete machine.
Brief description of the drawings
Fig. 1 is that a kind of agricultural rotary tiller of the utility model is looked sectional structure schematic diagram with the master of dustproof rotary ploughing cutter shaft.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In figure: 1, rotary ploughing cutter shaft central siphon 2, rotary tillage cutter holder 3, spindle nose 4, adpting flange 5, coupling sleeve 6, gear soil ring 7, side plate bearing chamber 8, casing bearing chamber 9, bearing
As shown in drawings, the utility model is dustproof rotary ploughing cutter shaft for a kind of agricultural rotary tiller, include rotary ploughing cutter shaft central siphon 1, on rotary ploughing cutter shaft central siphon 1 circumference, be welded with rotary tillage cutter holder 2, spindle nose 3 and adpting flange 4 are welded on respectively rotary ploughing cutter shaft central siphon 1 two ends, coupling sleeve 5 is arranged on adpting flange 4, on spindle nose 3 and coupling sleeve 5, be welded with respectively gear soil ring 6, gear soil ring 6 on spindle nose 3 matches with the draw-in groove of side plate bearing chamber 7, gear soil ring 6 on coupling sleeve 5 matches with the draw-in groove of casing bearing chamber 8, while preventing operation, dust enters in the bearing 9 of side plate bearing chamber and casing bearing chamber.
When operation, coupling sleeve 5 is connected with the power take-off of gear-shifting box of rotary cultivator, side plate bearing chamber 7 is fixed on rotovator framework lateral plate with bolt, rotary blade is installed on rotary tillage cutter holder 2 successively with bolt, rotary ploughing cutter shaft does circumference rotation under speed changing box power output shaft drives, the rotary blade being arranged on rotary ploughing cutter shaft is pulverized soil spin-up, completes rotary tillage process.
Dustproof rotary ploughing cutter shaft for the agricultural rotary tiller that the utility model provides, rational in infrastructure, cost is low, can effectively prevent the damage of dust to bearing, has extended the service life of bearing, has greatly improved the operating efficiency of complete machine.
