Description
Technical field
The utility model relates to agricultural machine field, relates in particular to a kind of laser pickoff arrangement for adjusting height that is used for the level land shovel.
Background technology
Land readjustment is an important step in the consolidation work.Studies show that land readjustment increases income etc. for the control of farmland water-saving, weeds, crop all obvious effects.Utilize the laser controlled leveling technology to level land, level land precision height, simple to operate, the operating efficiency height.The laser land leveling shovel is made up of generating laser, hydraulic jack, laser pickoff, control valve group, fuel tank, hitch frame, gear oil pump, controller and perching knife etc.The laser pick-off apparatus that uses all is fixedly mounted on the column at present.Before the work of level land, earlier laser pickoff is fixedly mounted on the column, roughly estimate the dispersed elevation of field piece, can not accurately know the actual elevation in target field, if eat the soil amount too much in the process of level land, the laser pickoff range of receiving surpasses range, then need stop level land work, manually reset the receiver installation site, scraper bowl is laid down for interior cubic metre of earth.
The level land shovelman that prior art is described in conjunction with Fig. 1 makes principle and defective: before carrying out the farmland grading operation, at first in farmland central authorities generating laser (in as Fig. 1 (a)) is installed, is guaranteed that Laser emission receives the space clear.The laser plane that sends with generating laser is the level land height datum, laser pickoff receives laser signal and measures the difference of current level land shovel loca elevation and height datum, regulate the flexible of level land shovel hydraulic jack by controller drive control valve group, realize the real-time control of blade height, reach the effect of leveling land.When level land shovel is operated in elevation less than the zone, farmland of dispersed elevation (in as Fig. 1 (b)), because laser pickoff is lower than the emission level face, and still in range of receiving, this moment, hydraulic jack stretched out, with cubic metre of earth uninstalling in the scraper bowl.If the plot elevation is more and more lower, when this moment, laser pickoff exceeded range of receiving, the level land shovel kept motionless.When level land shovel is operated in elevation greater than the zone, farmland of dispersed elevation (in as Fig. 1 (c)), because laser pickoff is higher than the emission level face, and still in range of receiving, this moment, hydraulic jack shrank, and the control perching knife descends, level land shovel beginning scraping.When level land shovel be operated in can received signal above laser pickoff the elevation zone time, this moment, under forklift deadweight effect, the level land shovel kept the scraping state always because perching knife has certain penetrating angle.When the soil amount of eating was more and more, because the range of receiving of receiver is limited, the flexible range of control oil cylinder was less, can't reach the purpose of accumulation in the unloading forklift cubic metre of earth this moment by manual control hydraulic cylinder action.Existing working method must quit work, and the fixed position by the manual adjustments laser pickoff is to unload soil, and making influences operating efficiency by grading operation process device complex operation.Simultaneously, because the laser pickoff position is difficult for regulating, forklift is difficult to unload soil, and the working resistance that causes forklift and tractor to be subjected to is also increasing, and long-time overload work very easily damages level land shovel and tractor.
