Abstract
The invention discloses an adaptive disc type stumping device. The device is in a telescopic arm structure which is telescoped by a telescopic oil cylinder; a telescopic arm and a cutting knife part are driven to move from side to side by the side-to-side movement of the oil cylinder; the ground clearance of a cutting knife disc is adjusted by lifting the oil cylinder; the telescopic arm can swing in an angle range of 150 degrees by a worm and worm wheel mechanism; the telescopic arm can be lifted and descended by the pitching movement of the oil cylinder; the cutting knife disc is driven by a hydraulic motor (in an electric motor or other mechanical transmission form) to rotate at high speed, and knife blades fixed on the cutting knife disc do centrifugal movement to cut off shrubs; the cutting knife disc and the telescopic arm are hinged so as to adapt to the change of the pitch angle of the telescopic arm and keep the cutting knife disc horizontal; and the knife blades are in an active avoiding structure, so that when a hard object is encountered and can not be cut off, the knife blades are passively retracted to prevent the cutting knife part of the stumping device from being damaged. The adaptive disc type stumping device is used for cutting shrubs and stumping on a sandy ground, has strong adaptability to the shrubs grown on a complex sandy ground, and can meet the requirement of long-time operation in a large area.
Description
Technical field
The present invention relates to a kind of device that is used for sand ground shrub harvesting stump, relate in particular to a kind of self-adaptation type disc type stump device.
Background technology
In recent years, in order to check winds and fix drifting sand, to conserve water and soil and the ecological balance, desert area establishing in large scale desert shrub.Spinney not only has ecological benefits, can also be used for pulping and paper-making, produce feed, biomass power generation as the raw material of industry.According to the biological property of desert shrub, per 3～5 years necessary stumps, growth is accelerated behind the stump, and sprouting power is strengthened, and has rejuvenation effect.
The small-sized backpack or the shoulder-hanging brush saw that generally use in the prior art can't satisfy requirement long-time, the large tracts of land operation, and labour intensity are big, and the vibration in the brush process is bigger to the human influence.
Summary of the invention
It is strong to the purpose of this invention is to provide a kind of shrub adaptability to complicated sand ground face, can satisfy the self-adaptation type disc type stump device of the requirement of long-time, large tracts of land operation.
The objective of the invention is to realize: self-adaptation type disc type stump device of the present invention through following technical scheme; Comprise cutting part, telescopic arm and suspension arrangement; It is characterized in that; The front end of said telescopic arm is connected with said cutting part, and the rear end is connected on the suspension arrangement through movable stand, and said telescopic arm is provided with telescopic oil cylinder;
Be provided with lifting drive, move left and right drive unit between said movable stand and the said suspension arrangement;
Be provided with the drive unit that swings, pitch drive between said telescopic arm and the said movable stand.
Technical scheme by the invention described above provides can be found out; Self-adaptation type disc type stump device of the present invention; Owing to take the telescopic boom structure, and be provided with lifting drive, move left and right drive unit, the drive unit that swings, pitch drive etc., when being used for sand ground brush stump; Shrub adaptability to complicated sand ground face is strong, can satisfy requirement long-time, the large tracts of land operation.
Description of drawings
Fig. 1 is the structural representation of self-adaptation type disc type stump device of the present invention.
1. suspension arrangement, 2. hoist cylinder, 3. left and right sides oil cylinder, 4. moving track, 5. worm-and-wheel gear, 6. telescopic oil cylinder, 7. pitching oil cylinder, 8. telescopic arm, 9. cutting part, 10. brush motor, 11. circular beater plates, 12. blades.
Embodiment
Self-adaptation type disc type stump device of the present invention; Its preferable embodiment is as shown in Figure 1; Comprise cutting part, telescopic arm and suspension arrangement; The front end of said telescopic arm is connected with said cutting part, and the rear end is connected on the suspension arrangement through movable stand, and said telescopic arm is provided with telescopic oil cylinder;
Be provided with lifting drive, move left and right drive unit between said movable stand and the said suspension arrangement;
Be provided with the drive unit that swings, pitch drive between said telescopic arm and the said movable stand.
Said movable stand is provided with the move left and right track and moves up and down slideway, and said lifting drive comprises hoist cylinder, and said move left and right drive unit comprises left and right sides oil cylinder,
The said drive unit that swings comprises the worm-and-wheel gear of being located on the said movable stand, and the rear end of said telescopic arm and the turning cylinder of said worm gear are hinged.
Said pitch drive comprises the turning cylinder of being located at said worm gear and the hoist cylinder between the telescopic arm.
The pendulum angle of said telescopic arm is 150 °.
Said cutting part comprises circular beater plate, and the turning cylinder of said circular beater plate is connected with the brush motor, and the edge of said circular beater plate is provided with blade.
The front end of said telescopic arm and said cutter part are hinged.Said blade is connected with cutterhead through the avoiding-type structure.
Self-adaptation type disc type stump device of the present invention, this device is taked the telescopic boom structure, is realized stretching by the telescopic oil cylinder action, has increased job area; Left and right sides cylinder action drives telescopic arm and cutting part move left and right, further increases job area; Through hoist cylinder, can adjust the cutter disk road clearance, make it adapt to complicated sandy land surface, guarantee the height of stump; By the worm-and-wheel gear of fluid motor-driven, can realize the swing of telescopic arm in 150 ° of angular regions, for cutting blade provides feed motion; Through the pitching cylinder action, can realize lifting and reduce of telescopic arm, cooperate hoist cylinder, better control the height of stump; Cutterhead is high speed rotating under the driving of hydraulic motor, and the blade that is fixed on the cutterhead is done centrifugal motion, and shrub is cut off; This cutterhead and telescopic arm type of attachment are hinged, under the effect of gravity, can adapt to the variation of telescopic arm luffing angle automatically, keep the cutterhead level; Blade structure is an avoiding-type initiatively, when running into hard object and can't cut off, can passive withdrawal, and avoid the cutting part of stump device is caused damage.
The present invention is a kind of big-and-middle-sized brush stump device, needs the characteristic that regular stump fosters and develops to shrub.This device is loaded on the special vehicle of desert, has good sand ground trafficability characteristic, adopts hydraulic system to drive, and brush efficient is high, wide adaptability.Adapt to complicated sand ground operation surface, guarantee the stump requirement for height.Brush efficient is high, and automaticity is high, can reduce operator's labour intensity greatly; This invention can be satisfied the requirement of long working, thereby has solved the difficult problem of domestic extensive spinney harvesting; Shrub adaptability to complicated sand ground face is strong; The harvesting shrub has not only been satisfied the biological nature that regular stump is fostered, and the raw material of industry can also be provided, and is used for pulping and paper-making, biomass power generation etc., when bringing ecological benefits, can also produce huge economic benefit.
