Embodiment:
See accompanying drawing 1～Fig. 6, the utility model is to drag formula laser land leveling shovel, comprises level land shovel and Askania, and Askania comprises fuel tank 1, oil filter 2, gear oil pump 3, hydraulic jack 4 and oil pipe 5; The level land shovel comprises draw bar 11, bidirectional modulation screw rod 12, level land shovel framework 13, perching knife 14, supports wheel carrier 15, and it is characterized in that: respectively there is a side shield 16 shovel framework 13 both sides, level land, are welded to connect with level land shovel framework to be one; Perching knife 14 is a symmetrical structure, and all there is cutting blade both sides; Generating laser 6, laser pickoff 7, controller 8, pressure control drain charge valve, ratio electrically-controlled valve, electric control one-way valve have been increased in the Askania, wherein, pressure control drain charge valve, ratio electrically-controlled valve, electric control one-way valve are three control valve groups 9 that valve is integrated, control valve group 9 has four oil pipes 5, wherein two oil pipes 5 are connected with the big chamber and the loculus of hydraulic jack 4 respectively, article one, oil pipe 5 links to each other with fuel tank 1, and another oil pipe 5 is connected with oil filter 2; Laser pickoff 7 outputs by cable be connected with controller 8 inputs, controller 8 outputs are connected with ratio electrically-controlled valve in the control valve group 9 by cable.Askania is placed on the shovel framework of level land, forms independently hydraulic system.
Fuel tank is that 60 liters, oil filter (being made up of oil header WU100, filter ZU-H00 and air cleaner EF4-50), gear oil pump model are that CBT-E525, hydraulic jack model are HSGF
*Φ 80/ Φ 45, control valve group model are that FC-10A, generating laser model are that L-600, laser pickoff model are that R2S-S, controller model are CBT20T0.
Use the oil circuit of three seperating vales to see Fig. 7.Narrate the effect of three valves below respectively, pressure control drain charge valve 9-1, hydraulic oil does not have pressure by drain charge valve oil sump tank at ordinary times, and system does not generate heat, and energy consumption is low; When to the big chamber of oil cylinder fuel feeding, the drain charge valve is in closed condition, in case surpass safe pressure, the drain charge valve is opened overflow, and when to oil cylinder loculus fuel feeding, oil directly refluxes altogether, only has a small amount of repairing to enter loculus, by level land shovel deadweight the pushing of the oil in the big chamber is refluxed; The effect of electric control one-way valve 9-3 is that electric control one-way valve is motionless when to the big chamber of oil cylinder fuel feeding, can be unidirectional oily excessively, and when to oil cylinder loculus fuel feeding, electric control one-way valve action, but big chamber oil return; The big chamber backflow of ratio electrically-controlled valve control 9-2 system hydraulic jack throttle opening, regulator solution compressing cylinder stretching speed.
Originally dragging formula laser land leveling shovel is tractor-drawn by wheeled or crawler belt, and whole level land shovel hangs draw bar by bearing pin and is connected with the tractor-drawn hook, by the tractor-drawn operation.When tractor-drawn point height change,, guarantee operating efficiency by the cutting angle degree of adjusting screw(rod) length adjustment perching knife.Perching knife is a symmetrical structure, and all there is cutting blade both sides, when a side tool sharpening decreases, perching knife can be pulled down refitting, uses the opposite side blade to carry out operation.Support wheel carrier and be connected with level land shovel framework with the adjusting oil cylinder by bearing pin respectively, the flexible support wheel carrier that makes of hydraulic jack rotates around connecting pin, and the level land shovel is propped or put down, and realization is unloaded soil and cut native action.
Above-mentioned to drag formula laser land leveling shovel be with Askania and drag formula level land shovel to be assembled into one, and can carry out the meticulous smooth operation in soil, farmland, substitutes existing conventional mechanical planarization soil equipment (as bulldozer, scraper, traditional land leveller etc.).
This device is owing to the pressure control drain charge valve, ratio electrically-controlled valve, the electric control one-way valve that adopt are three control valve groups that valve is integrated, and the oil circuit between them connects in inside, so, drag simple in structure, compact, the dependable performance of formula laser land leveling shovel.
