Abstract

Paddy field banking machine rotary knife axis assembly belongs to agricultural machinery；It is fixedly mounted with A tool rests, B tool rests successively on cutter shaft, throws local soil type's conjunction tool rest and roller frame, closed in A, B tool rest and throwing local soil type and be fixedly mounted with the native knife A of collection, the native knife B of collection and throwing local soil type conjunction knife on tool rest respectively, collect native knife A, B and throw local soil type and close knife in a circumferential direction mutually in dislocation configuration is intersected, collect native knife B tactical diameter Ф₂The tactical diameter Ф of knife is closed with throwing local soil type₁, the native knife A of collection tactical diameter Ф₃Magnitude relationship is：Ф₂>Ф₁>Ф₃, collect native knife B tactical diameter Ф₂Less than or equal to the overall diameter Ф of roller frame, N number of shaping compacting shell fragment is equipped with outer surface of cylinder；This assembly structure is novel, rationally, and using reliable, transaction capabilities are good, and it is high to build ridge quality.

Description

Paddy field banking machine rotary knife axis assembly

Technical field

The invention belongs to agricultural machinery, relates generally to a kind of rotary blade assembly on the ridger of paddy field one side.

Background technology

It is usually to build out new ridge by rotary-tillage suppressing on the basis of old stalk that ridger is repaiied in paddy field one side, but at present The ridge building rotary blade assembly developed only serves hack, collects the effect of soil, the ridge low intensity built out, the soil in ridge Earth tight ness rating is not high, in doughy state, drainage not only easily occurs, causes moisture loss in paddy field, ridge especially easily occurs Slump is metalled run out failure.

The content of the invention

The purpose of the present invention is aiming at the above-mentioned problems of the prior art, with reference to the actual need of paddy field production operation Ask, design a kind of paddy field banking machine of new construction rotary knife axis assembly, reach the paddy field ridge soil tight ness rating built out it is big, Bulk strength is high, water-tight, not slump, service life length purpose.

What the purpose of the invention was realized in:It is fixedly mounted with A tool rests, B tool rests successively on cutter shaft, throws local soil type's conjunction tool rest With roller frame, closed in described A tool rests, B tool rests and throwing local soil type and be fixedly mounted with the native knife A of collection, the native knife B of collection and the conjunction of throwing local soil type on tool rest respectively Knife, it is mutually in intersect dislocation to configure in a circumferential direction that knife closes in collection native knife A, the native knife B of collection and the throwing local soil type, collects returning for native knife B Turn diameter Ф₂The tactical diameter Ф of knife is closed with throwing local soil type₁, the native knife A of collection tactical diameter Ф₃Between magnitude relationship be Ф₂>Ф₁> Ф₃, the tactical diameter Ф of the native knife B of collection₂Less than or equal to the roller overall diameter Ф of roller frame, in the roller of the roller frame The overall uniform equipped N number of shaping compacting shell fragment of covering, so far forms paddy field banking machine rotary knife axis assembly on outer surface.

It is of the invention that using collecting, native knife A, B collection sufficient twice are native to close knife for native and shaping compacting shell fragment to the ridge with throwing local soil type Continuous rolling type squeeze job inside body one side, is greatly improved the soil compaction of Xiu Geng ridge body, enhances ridge body Bulk strength, not permeable leak, slump is not easy, service life length, this cutter shaft assembly structure is novel, reasonable, uses reliable, workability Can be good, it is high to build ridge quality.

Piece number explanation in figure：

1st, knife, 2, the native knife B of collection, 3, the native knife A of collection, 4, cutter shaft, 5, A tool rests, 6, B tool rests, 7, throwing local soil type conjunction knife close in throwing local soil type Seat, 8, shaping compacting shell fragment, 9, roller frame, 10, handle of a knife, 11, cone angle shape elasticity arc surfaced cutter hub.

Embodiment

Embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.A kind of paddy field banking machine rotary knife axis are total Into being fixedly mounted with A tool rests 5, B tool rests 6 successively on cutter shaft 4, throw local soil type and close tool rest 7 and roller frame 9, in described A tool rests 5, B tool rests 6 and throw local soil type and close to be fixedly mounted with the native knife A3 of collection, the native knife B2 of collection on tool rest 7 respectively and throw local soil type and close knife 1, the native knife A3 of the collection, the native knife of collection Knife 1 closes in a circumferential direction mutually in the configuration that misplaces is intersected in B2 and throwing local soil type, collects native knife B2 tactical diameter Ф₂Closed with throwing local soil type The tactical diameter Ф of knife 1₁, the native knife A3 of collection tactical diameter Ф₃Between magnitude relationship be Ф₂>Ф₁>Ф₃, the native knife B2 of collection Tactical diameter Ф₂It is overall on the outer surface of cylinder of the roller frame 9 less than or equal to the roller overall diameter Ф of roller frame 9 The uniform equipped N number of shaping compacting shell fragment 8 of covering.Knife 1 closes by handle of a knife 10, the structure of cone angle shape elasticity arc surfaced cutter hub 11 in the throwing local soil type Into the cone angle shape elasticity arc surfaced cutter hub 11 is packed on the downside leading section of handle of a knife 10.

During operation, while this rotary knife axis assembly does the motion of circumferencial direction active rotation under the driving of cutter shaft 4, rotary blade The overall axis direction forward movement along its cutter shaft 4 of axle assembly, drive and collect native knife A, B3,2 spin line tracking motion, collect native knife A, B3,2 the ridge soil in the old side wall of the ridge one is completed to cut, hack, the native operation of collection, while arc ditch is formed in the old side wall of the ridge one Groove, the local soil type of throwing thereafter conjunction knife 1 will collect native knife A, B3,2 native parts concentrated are thrown in the arcuate furrow in the old side wall of the ridge one, throw simultaneously The cone angle shape elasticity arc surfaced cutter hub 11 that local soil type is closed on knife 1 is done for the first time to being filled with native part in the old side wall of the ridge one in arcuate furrow Elasticity suppression, operation is made real, it is complete to native part in arcuate furrow after the shaping compacting shell fragment 8 on your outer surface of cylinder of roller frame 9 Operation is made real into the suppression of the second hypoelasticity.The present invention, which is greatly improved, builds ridge soil compaction.
