Description

A kind of rotary cultivator

Technical field

The present invention relates to agricultural machinery technological field, is specially a kind of rotary cultivator.

Background technology

The annual output of the current stalk in China is about more than 6.2 hundred million tons, and only 6% stalk is by returning to the field.Largely discarded, burnt Burn, cause environmental pollution and fire hazard to cause damages seriously to national economy.Straw-returning is classified as " rich by the Ministry of Agriculture in recent years Receipts plan " and the main contents of " fertile_soil plan ", and repeatedly send emergency notice, it is desirable to crop straw burning is forbidden in various regions, does conscientiously Good straw-returning and comprehensive utilization work.

Current single-shaft rotary cultivator tilling depth is shallow（Less than 16cm）, the stalk ratio in soil is too high, influences the normal raw of wheat It is long.The scheme of solution mainly has two kinds, and one kind uses ploughing, and also needs multiple working procedure to plant after ploughing, spent time length, Efficiency is low, is not easy to realize compoundization of operation.Another kind still uses rotary tillage, and stalk is realized by increasing the tilling depth of rotary tillage Total crop return, can also realize compoundization of operation.Therefore it is still preferable selection using rotary tillage.And existing rotary cultivator, Such as vertical milling formula twin shaft layering among a kind of central transmission described in the Chinese invention patent of Application No. 201410243083.7 Cut rotary cultivator, including power traction machine, chain wheel driving mechanism, central gearing box, first axle rotary blade and the second axis rotary blade； Power traction machine is connected with chain wheel driving mechanism, and central gearing box includes the front support shell and rear support shell in herringbone distribution, First axle rotary blade cutter shaft is rotatably connected to front support shell lower end, and the second axis rotary blade cutter shaft props up after being rotatably connected to Support shell lower end, the setting parallel with the second axis rotary blade cutter shaft axis of first axle rotary blade cutter shaft, first axle rotary blade turning circle The lower edge in week is higher than the lower edge of the second axis rotary blade revolution circumference, first axle rotary blade cutter shaft, the second axis rotary blade cutter shaft and chain Wheel drive mechanism is sequentially connected, and intermediate supports shell is equipped between front support shell and rear support shell on the central gearing box, in Between in supporting shell rotatably arranged with there is vertical milling rotary blade, vertical milling rotary blade cutter shaft is sequentially connected with the chain wheel driving mechanism, The cultivation area covering first axle rotary blade of vertical milling rotary blade and the farming blind area of the second axis rotary blade.Its shortcoming is：The rotation The machine of ploughing hack energy force difference, easily adheres to soil block or winding weeds, farming is not carried out at work on rotary blade blade.

The content of the invention

It is an object of the present invention to provide a kind of rotary cultivator, has the characteristics that broken soil performance is good, rotary tillage effect is good.

The present invention above-mentioned technical purpose technical scheme is that：A kind of rotary cultivator, including vehicle frame, The dynamic traction device and the rotary cultivator attachment for being arranged on the vehicle frame rear, the rotary cultivator attachment bag being arranged in front of the vehicle frame Gear frame, transmission mechanism, rotary knife component and protective cover are included, the gear frame is fixed on the vehicle frame, and the transmission mechanism is set Put in the gear frame and drive the rotary knife component to rotate, the protective cover is installed on the vehicle frame, the rotary knife group Part is arranged in the protective cover, and the rotary knife component includes cutter shaft and the rotary knife rotated with the cutter shaft, and the rotary knife is spiral shell Rotation shape is distributed on the cutter shaft, and cutter is equipped with the protective cover, and the cutter is arranged between adjacent two rotary knife, One end of the cutter is connected with reciprocal thrust gear, and the other end of the cutter is directed toward the cutter shaft axle center, described back and forth to push away Telephone-moving structure is arranged on the outside of the protective cover and drives the cutter to be moved back and forth along the cutter shaft radial direction.

For the present invention by setting cutter between adjacent rotary knife, rotary knife makes it form opposite cutting with cutter by rotating Action, so that the weeds between rotary knife or soil block are shredded, and cutter is connected on reciprocal thrust gear, makes cutter in cutter shaft Radial direction is moved back and forth, and cutter is formed opposite cutting action in cutter shaft radial direction with rotary knife, is both improved cutter Cutting effect, and the soil block on rotary knife or weeds can be will be attached to and peeled off.Simultaneously because cutter shaft axle center is directed toward in the end of cutter, Cutter moves back and forth the radial direction that direction is cutter shaft, makes cutter in cutting with maximum effective cut length.

Preferably, the reciprocal thrust gear includes fixed seat, knife rest, transmission arm and drive, the fixed seat is consolidated Surely the outside of protective cover is connected to, the protective cover, which is equipped with, makes the cutter enter the protective cover on the outside of the protective cover Inner side goes out the edge of a knife, and the cutter is fixed on the knife rest；The drive is driven by the transmission mechanism and rotated, described One end of transmission arm is articulated with the knife rest, its other end bias is articulated with the drive, when the drive rotates When, the transmission arm promotes the knife rest to be relatively fixed seat movement.

Preferably, the fixed seat is equipped with guide rod, the knife rest is slidably connected on the guide rod.

Preferably, the side away from cutter is equipped with stabiliser bar on the knife rest, one end of the stabiliser bar is fixed in institute State on knife rest, its other end is socketed on the guide rod and relatively described guide rod slides.

Preferably, the cutter is equipped with sawtooth, the sawtooth is inclined on the cutter.

Preferably, the rotary knife includes knife body, is arranged on the mounting portion of knife body one end and to be arranged on knife body another The cutting part of one end, the knife body are convex structure, and are bent to the rotary knife rotation direction；The cutting part relative to The knife body is obliquely installed along the cutter shaft axial direction, and the angle between the cutting part and the knife body is 100 °- 120°。

Preferably, the cutting part is included in upper and lower spaced first cutting part and the second cutting part, described the One cutting part is equipped with cutting cutting edge of a knife or a sword, and the cutting cutting edge of a knife or a sword is made of two intersecting cutting edges, and the cutting cutting edge of a knife or a sword turns to the rotary knife Dynamic direction protrudes from second cutting part.

Preferably, be equipped with diversion trench between first cutting part and second cutting part, the diversion trench is along institute Rotary knife rotation direction is stated through the front and rear sides of the cutting part.

Preferably, being socketed several knife cylinders being spaced apart on the cutter shaft, the knife cylinder is equipped with tool apron, the rotation Knife is plugged on the tool apron.

Preferably, the tool apron is telescopic structure, including the fixation tool apron that is fixed on knife cylinder and relatively described solid The movable tool apron of stationary knife seat movement, the fixed tool apron are equipped with the regulating part of adjusting activity tool apron displacement distance.

Beneficial effects of the present invention：The soil block or weeds that the present invention can effectively will be attached on rotary knife are peeled off or cut It is broken, broken soil performance and rotary tillage effect are improved, and the embedded depth of rotary knife can be adjusted, rotary knife soil-entering resistance is small, reduces It cuts and crushes the power consumption of soil.
