Abstract
The utility model discloses a multiple floating function device of a land leveller shovel plate. The multiple floating function device of the land leveller shovel plate is composed of an oil tank, an oil pump, an operating valve set, a balance valve, an energy accumulator, a shovel plate lifting oil cylinder, a first magnetic exchange valve, a second magnetic exchange valve and a third magnetic exchange valve. The multiple floating function device of the land leveller shovel plate is characterized in that a rodless cavity of the shovel plate lifting oil cylinder is connected with the first magnetic exchange valve, the second magnetic exchange valve and the balance valve. A rod cavity of the shovel plate lifting oil cylinder is connected with the first magnetic exchange valve, the third magnetic exchange valve and the balance valve. The energy accumulator is connected with the first magnetic exchange valve. The balance valve is respectively connected with the second magnetic exchange valve and the third magnetic exchange valve in a parallel mode, and then connected with the operating valve set. An oil inlet of the oil pump is connected with the oil tank. An oil outlet of the oil pump is connected with the operating valve set. When electric combination of the magnetic exchange valves is controlled, the shovel plate lifting oil cylinder is in a multiple floating functions state. The multiple floating function device of the land leveller shovel plate can achieve four operating modes of the shovel plate according to different working conditions, wherein the four operating modes are light load floating, heavy load floating, dead load floating and fixed locking. The multiple floating function device of the land leveller shovel plate is novel in conception, compact in structure, easy to operate, good in using effects, and capable of expanding using ranges of a land leveler.
Description
Technical field
The utility model belongs to the land leveller technical field, is a kind of novel multiple float function device of level land mechanical shovel soil plate.
Background technology
The equipment of land leveller is divided into groundwork device and auxiliary working apparatus, and the shovel of land leveller soil plate is the groundwork device of land leveller; During land leveller work, by the native angle of height, angle of revolution, shovel of the native plate of adjustment shovel and along with coming in to finish work such as soil-shifting, snow removing before the machine.The Height Adjustment of level land mechanical shovel soil plate has only a kind of stationary state or a kind of quick condition at present.But when removing the snow, opening ice, clear up special operation operating modes such as road surface, mine road, can not do further adjustment according to the special operation operating mode.The utility model provides a kind of novel level land mechanical shovel soil plate multiple float function device, can realize that the underloading of the native plate of shovel is floated, heavy duty is floated, deadweight is floated and fixing four kinds of duties of locking according to different operating modes, has enlarged the scope of application of land leveller.
Summary of the invention
The purpose of this utility model provides a kind of novel multiple float function device of level land mechanical shovel soil plate.The purpose of this utility model is achieved in that the multiple float function device of level land mechanical shovel soil plate is made up of fuel tank, oil pump, operating valve set, equalizing valve, accumulator, shovel soil plate hoist cylinder, solenoid operated directional valve I, solenoid operated directional valve II, solenoid operated directional valve III.The rodless cavity that shovels native plate hoist cylinder connects solenoid operated directional valve I, solenoid operated directional valve II and equalizing valve; The rod chamber that shovels native plate hoist cylinder connects solenoid operated directional valve I, solenoid operated directional valve III and equalizing valve.Accumulator is connected with solenoid operated directional valve I.Equalizing valve is connected with operating valve set more respectively with solenoid operated directional valve II, solenoid operated directional valve III and connect.The oil pump oil-in is connected with fuel tank; The oil pump oil-out is connected with operating valve set.
When solenoid operated directional valve I, solenoid operated directional valve II, solenoid operated directional valve III must not electricity, to shovel native plate hoist cylinder and be in fixedly locking duty, the position of shoveling native plate hoist cylinder is under operator's the control, shovels native plate in relatively-stationary work plane movement; When solenoid operated directional valve II, solenoid operated directional valve III simultaneously when electric, shovel rod chamber and the direct UNICOM of the rodless cavity fuel tank of native plate hoist cylinder, shovel native plate hoist cylinder and be in the deadweight duty of floating, shovel native plate and be attached on the work plane mobile by its weight; When the upper end of solenoid operated directional valve I electromagnetic valve and solenoid operated directional valve III simultaneously when electric, shovel the direct UNICOM of native plate hoist cylinder rod chamber fuel tank, accumulator is communicated with the rodless cavity of the native plate hoist cylinder of shovel by solenoid operated directional valve I, shovel native plate hoist cylinder and be in the unsteady duty of heavy duty, though make the native plate of shovel be in unsteady operating mode, but there is a pressure pressing it all the time, makes the native plate of shovel be close to work plane all the time and move; When the lower end of solenoid operated directional valve I electromagnetic valve and solenoid operated directional valve II simultaneously when electric, shovel the direct UNICOM of native plate hoist cylinder rodless cavity fuel tank, accumulator is communicated with the rod chamber of the native plate hoist cylinder of shovel by solenoid operated directional valve I, shovel native plate hoist cylinder and be in the unsteady duty of underloading, though make the native plate of shovel be in unsteady operating mode, but there is a Tuo Lituo it all the time, overcome part gravity, make the native plate of shovel be attached on the work plane mobile with a less power all the time.
So just realized the multiple float function of level land mechanical shovel soil plate, it can realize that the underloading of the native plate of shovel is floated, heavy duty is floated, deadweight is floated and fixing four kinds of duties of locking according to different operating modes.The utility model is novel, compact conformation, easy operating, result of use are good, has enlarged the scope of application of land leveller.
