Description
Technical field
The present invention relates to a kind of farm flattening equipments, and in particular to a kind of paddy field laser flatting machine of profiling back-up roller.
Background technique
Smooth paddy field is the premise of mechanized farming plantation, has and improves mechanical efficiency, is poured water uniformly, and water money is saved
The advantages that source facilitates field management, improves utilization rate of fertilizer, improve crop yield." a kind of folding paddy field is smooth for patent of invention
Machine " (CN103039142A) provides that a kind of structure is simple, practicability is good, folding paddy field leveler.But the paddy field leveler
Tractor trifilar suspension can only be manually adjusted when use and realizes equipment up and down motion operation, be unable to reach the requirement on accurate level land.
Patent of invention " a kind of paddy field laser flatting machine " (CN101223841A) judges the height of flat shovel by the contraposition of laser signal
Degree, the height of flat shovel is adjusted by elevation hydraulic cylinder and parallel linkage.But the laser flatting machine can not be dragged with wheeled
The three-link hitch of machine drawing is connected.Patent of invention " a kind of land level scraper elevation regulating mechanism of paddy field laser flatting machine "
(CN103583101A) parallelogram mechanism is constituted by suspension mounting rack, flat shovel rotating turret, synchronous parallel bar, to control
Make elevation and the horizontal movement of flat shovel.Patent of invention " a kind of rotary type paddy field laser flatting machine " (CN105874929A) passes through
It moves synchronously frame and drives laser pickoff synchronization lifting.But both laser flatting machines are unable to improve tractor pitch attitude frequency
Influence of numerous variation to land level scraper.
In actual application, the elevation of land level scraper, which is adjusted, is not only caused flat shovel liter by flat shovel itself is overweight
Drop is difficult, and also mainly by tractor, when paddy field hardcore is walked, its pitch attitude frequently changes and influenced.When tractor is bowed
When facing upward posture and frequently changing, laser pickoff issues electric signal after receiving signal to controller to command HYDRAULIC CONTROL SYSTEM
Elevation cylinder movement.This process receives signal and feeds back to since the time of tractor attitudes vibration when paddy field is walked is very fast
There is lag to adjust the run duration of elevation oil cylinder, it is difficult to reach ideal leveling effect.
Therefore, the present invention mainly utilizes the float function of the three-link hitch of wheeled tractor, using profiling back-up roller
Cause pitch attitude frequently to change the influence to laser land leveling machine operation to reduce tractor by paddy field hardcore injustice, reduces
The muck haulage resistance of land level scraper, enhances the versatility of laser flatting machine, further to field hack, bury stubble, it is wheeled dilatory to improve
Level land precision when machine is used for grading operation and the problems such as operating efficiency.
