Abstract

The utility model discloses breaking blades and a breaker for root stubbles of crops. The blades are separately arranged and installed on a knife shaft along the direction of the knife shaft, a plane of the blades is perpendicular to that of the knife shaft, cutting edges of the blades face to the direction of rotation of the knife shaft, and the distance from a rotation center of the blades to each point of the cutting edges is gradually enlarged from the root portion of the cutting edge to the tail end of the cutting edge. When the breaker carries out breaking the root stubbles in fields with matching tractors, the blades not only break the large root stubbles into pieces at the position at which the breaker passes, but also decreases agitation and throw of the soil by the blades in the soil. The blades employ the convex arc shaped cutting edges, the knife shaft drives the blades to rotate along the negative direction of knifepoint in operation, firstly the root portion of the blade presses the root stubbles, then the cutting edge gradually cuts in from the root portion to the knife point, the power consumption is largely reduced by the cutting mode, therefore the breaking blades and the breaker can chop the root stubbles and underground root systems together with thorough breaking and fine effect of application to farmlands.

Description

Broken blade of crops root stubble and crops root stubble breaker
Technical field
The utility model relates to broken blade of a kind of crops root stubble and crops root stubble breaker.
Background technology
Existing corn combine and straw crushing and field-returning machine are to be cooperated by the moving knife of high speed rotating to be positioned at the stationary knife crushing maize stalk pulverized on the housing, because the limitation of its structure, moving knife can't bury and handle the root stubble, if will be with its crushing maize root stubble, just must carry out by a relatively large margin improvement to its overall structure; Moreover in a single day the moving knife of high speed rotating buries, and just needs to consume very big power, so present corn combine and straw crushing and field-returning machine are only handled maize straw, seldom handles the root stubble.But, the root stubble is not handled, the growth of crops is very unfavorable in season to next, people attempt to increase on corn strew grinding return-to-field machinery and join rotary ploughing part and finish crushed stalk and root stubble simultaneously and handle, but rotary ploughing part is to the stirring of soil and toss serious, power consumption is excessive, and can not be satisfactory to the crushing effect of root stubble.
The utility model content
First purpose of the present utility model provides the blade of the broken crops root of a kind of specialty stubble.
Second purpose of the present utility model provides the root stubble breaker of the broken crops root of a kind of specialty stubble.
For realizing first purpose, the utility model adopts following technical scheme: the broken blade of crops root stubble, when blade is fixedly mounted on the rotatable cutter shaft, the plane at blade place is vertical mutually with cutter shaft, blade on the blade is towards the direction of rotation of cutter shaft, and the pivot of blade distance of each point to the blade strengthens gradually from blade root to blade end.
The curved strip of blade cutter hub, blade is located at the chimb of arc cutter hub, is provided with to be used for the installation portion that is connected with cutter shaft on the cutter hub of blade root.
The blade cutter hub is in the form of annular discs, is provided with a cutter tooth with convex blade on the circumference of cutter hub at least, and the centre of disk cutter hub is installed together by an installing hole and cutter shaft, and the center of installing hole overlaps with the pivot of blade.
Described blade camber line is involute or spiral of Archimedes.
For realizing second purpose, the utility model adopts following technical scheme: crops root stubble breaker, comprise and by the cutter shaft of power drive rotation and to arrange the blade of installation at interval along cutter axis orientation, the plane at blade place is vertical mutually with cutter shaft, blade on the blade is towards the direction of rotation of cutter shaft, and the pivot of each blade distance of each point on this knife-blade strengthens gradually from blade root to blade end.
The curved strip of blade cutter hub, blade is located at the chimb of arc cutter hub, is provided with to be used for the installation portion that is connected with cutter shaft on the cutter hub of blade root, and axially mode is uniform in the shape of a spiral on the cutter shaft axial plane along cutter shaft for blade.
The curved strip of blade cutter hub, blade is located at the chimb of arc cutter hub, is provided with to be used for the installation portion that is connected with cutter shaft, along the circumferential direction uniform 2-4 blade on the same cross section of cutter shaft on the cutter hub of blade root.
The blade cutter hub is in the form of annular discs, is provided with a cutter tooth with convex blade on the circumference of cutter hub at least, and the centre of disk cutter hub is installed together by an installing hole and cutter shaft, and the center of installing hole overlaps with the pivot of blade.
Cutter shaft upper edge cutter shaft is the cutter tooth of the corresponding blade on each the blade installation site angle of setting that staggers successively in a circumferential direction axially.
Described blade camber line is involute or spiral of Archimedes.
After being installed on the cutter shaft, blade of the present utility model can implement field root stubble crushing operation with supporting tractor or straw cutting apparatus, in operation process, agricultural machinery power drive machines on one side moves ahead, drive on one side cutter shaft and traveling wheel of farm machine in the same way or counter-rotating, the cutter shaft that rotates is being with blade to rotate together again, and rotation of blade can be implemented cutting-up to the ground foreign material, root stubble and the underground root system that are positioned on the blade track; Because a plurality of blades have been installed on the cutter shaft at interval, and the plane at each blade place is all perpendicular to the cutter shaft axis, so place in the breaker process, blade is not only with the root stubble cutting-up slabbing of bulk, also reduce to bury blade to the stirring of soil with toss, improved the air quality of crushing operation.Blade adopts the convex blade, and the pivot of blade distance of each point to the blade strengthens gradually from blade root to blade end, the cutter shaft band the direction rotation of blade against point of a knife during work, the root of blade is pushed down root stubble and foreign material earlier, being rotated further along with cutter shaft then, blade progresses into cutting from the root to the point of a knife, and the degree of depth of otch strengthens gradually, the power consumption of this cutting mode greatly reduces, therefore, the utility model can shred in the lump to root stubble and underground root system, and is thoroughly broken, field effect is good, helps the growth of next crops in season.
In the utility model, the cutter tooth of the cutter shaft cutter angle of setting that staggers successively in a circumferential direction, purpose are in order to reduce the quantity of the blade that buries simultaneously at synchronization, and then further reduce required drive power, reduce the cost of corollary equipment.
