Description
Technical field
The invention belongs to meadow mechanized improvement technical field, be specifically related to a kind of meadow with profile modeling function and break ground and cut
Root machine.
Background technology
The grassland resources of China enriches, and its total amount and occupancy volume per person have all reached the first place of other land resources.But according to
Substantially estimating, current China there are about the meadow of 56.5% and degenerates.China's meadow Environmental Status needs improvement badly, and this is also that realization can
The key of sustainable development.As the main advantage herbage of China's Steppe and meadow steppe, Leymus chinensis (Trin.) Tzvel. grass yield in recent years is gradually
Decline.The soil permeability of Chinense Grassland is deteriorated, and water content reduces, reduction in porosity so that have the strongest asexual renewal energy
The breeding of the Leymus chinensis (Trin.) Tzvel. of power is restricted.
Some scholars of China have invented a kind of Chinense Grassland the method constantly seeking grassland improvement, Wang Dechen etc. in recent years
Mechanization is broken ground and is cut root rejuvenation growth-promoting new technique, has innovated the low disturbance in meadow, without turning over the mechanized farming technology of upturned soil, not sand.
But root cutter based on this principle still suffers from certain problem: as 9QP-830 type meadow break ground root cutter work on meadow time,
Its axle is easily bent deformation, and root cutter is easily damaged.Root cutter axle uses the mode of axis transmission, and root cutter can not accomplish to imitate
The effect of shape.When ground out-of-flatness, the active force of soil suffered by some cutterhead of root cutter increases, and cutterhead is to the power of cutter shaft also
Increasing, then easily cause the flexural deformation of axle, and then make root cutter and ground can not form vertical relation, so produce inclines
Angle makes root cutter be subject to the common effect of radially and laterally power, not only can affect and cut root effect, increase and soil resistance；More having can

Connecing, the power shaft of change speed gear box 306 is fixing with the rear output shaft of tractor rear end to be connected, and the rear output shaft input of tractor rear end is dynamic
Power, is delivered to main shaft 303 through change speed gear box 306, and the drive sprocket 305 being arranged on main shaft 303 is cut with being arranged on by chain 304
Root sprocket wheel 302 of cutting on root cutter shaft 301 carries out chain drive, thus drives the root cutter dish 202 being fixed in root cutter axle 301 to revolve
Turn, root cutter 201 high speed rotating cut off subsurface stratum Leymus chinensis (Trin.) Tzvel. horizontal walk rhizome, thus complete to cut root work.
As shown in Figure 4, feeler mechanism is automatically adjusted the height of root cutter dish 202 by copying spring 410 simultaneously: work as meadow
When there is depression situation, root cutter dish 202 and root cutter 201 height decline, and drive the rear end of the 4th link 405 to decline, draw
Play the 4th link 404 to rotate counterclockwise around the second connecting pin 415, and then cause the second link 403 around the first connecting pin
414 rotate counterclockwise, and the second link 403 moves downward relative to the 3rd link 404, and the decrement of copying spring 410 subtracts
Little, i.e. spring shortens, thus completes copy table；When protruding situation occurs in meadow, root cutter dish 202 and root cutter 201 are high
Degree rises, and the rear end of the 4th link 405 rises, causes the 4th link 405 to rotate clockwise around the second connecting pin 415,
And then cause the second link 403 to connect around the first connecting pin 414 clockwise movement, the second link 403 relative to the 3rd
Frame 404 moves upward, and the decrement of copying spring 410 increases, i.e. spring is elongated, thus completes copy table.
Copying spring 410 can ensure that root cutter 201 contacts with earth's surface all the time.By the screw-in degree of adjusting nut 409
The decrement of copying spring 410 can be changed, thus control the size of the cutting force of root cutter 201.When soil is hard, increase
The screw-in depth of adjusting nut 409 is to increase the pressure of copying spring 410；When soil is soft, reduce the rotation of adjusting nut 409
Enter the degree of depth to reduce the pressure of copying spring 410.Additionally, when running into barrier, root cutter 201 can pass through copying spring 410
Automatically adjust, reduce the damage to blade.This feeler mechanism ensure that root cutter structure carries out spirit with the fluctuating on earth's surface
Live and regulate, it is ensured that cut the concordance of the root degree of depth.
