Abstract
The invention discloses an intelligent lifting electronic automatic balancing system for walking tractors on sloping fields. The electronic automatic balancing system comprises a hydraulic lifting part and an electronic balancing part, wherein the hydraulic lifting part comprises left and right hydraulic oil cylinders, a lifting arm, a hydraulic oil pump and a multi-way distribution valve; the electronic balancing part comprises double-axis tilt angle sensors, relays, electromagnetic valves and an interlocking device. Power output by an internal combustion engine of a walking tractor drives the hydraulic oil pump; and the on and off of the multiple hydraulic electromagnetic valves is controlled through automatic adjustment of the electronic automatic balancing system, so that the left and right hydraulic oil cylinders extend or retreat to always keep the gravity center of slope walking tractor on the sloping fields in the balancing state.
Description
Technical field
The invention belongs to agricultural machinery technological field, particularly relate to a kind of electronic automatic balance system for intelligent elevated hillside fields walker tractor.
Background technology
At present, walker tractor occupies important position in farm power machinery, and it is not only movable dexterous, diverse in function, easy to operate, or the propulsion source of a lot of field machine, configuration rotary tillage, break ground, sow, plant, dig the various facility such as the land measure equal to fifteen mu in most parts of the Northeast and realize do mechanization operation.Walker tractor has transmission gearbox, and two jack shafts stretch out from the both sides of transmission gearbox respectively, and two drive wheels are arranged on two jack shafts respectively, and the height of two drive wheels can not regulate.At mountain area or high-land, peasant is when using walker tractor to carry out hillside fields transverse direction operation, if the gradient is comparatively large, two side drive wheel height can not regulate, and machine gravity sidesway easily makes walker tractor produce rollover, causes the accident.For addressing this problem, the patent No. be 87217114U patent discloses a kind of level Adjuster for hillside fields worker, this levelling gear fills the parallel shafts that is parallel to two wheel crank up axles in frame, with two rocking bars and two quadrant drive between parallel shafts and wheel crank up axle, parallel shafts is driven to rotate by a hydraulic ram or manual unit, make two wheels move simultaneously and move down, reach body leveling object.This device utilizing manual operations to carry out balancing of middle discovery is used to there is following problem: one is promptly and accurately to make trac. be in state of equilibrium all the time; Two is that operation is cumbersome, needs skilled operator.
Summary of the invention
The object of the invention is for prior art Problems existing, provide a kind of according to physical features gradient energy adjustment two wheels automatically, make walker tractor be in the electronic automatic balance system of state of equilibrium all the time.
The object of the invention is to be achieved through the following technical solutions, this electronic automatic balance system comprises hydraulic lifting portion and electronic equilibrium portion, described hydraulic lifting portion comprises left and right hydraulic ram, lift arm, hydraulic oil pump, Multi-path distribution valve, described change speed gear box is connected with one end of left and right lift arm by change speed gear box main driving axle, the other end of left and right lift arm is connected by the lower end of jack shaft with left and right hydraulic ram, the upper end of left and right hydraulic ram is fixed on hydraulic ram support, hydraulic oil pump is connected to hydraulic reservoir by oil inlet, the other end is connected to multipath hydraulic distributing valve, multipath hydraulic distributing valve four hydraulic oil pipes are connected respectively to entering of left and right hydraulic ram, oil out port, semiaxis connects tire by wheel hub, described electronic equilibrium portion comprises double-shaft tilt angle sensor, relay, electromagnetic valve, interlock, double-shaft tilt angle sensor is left, right, before, output switch amount signal during rear-inclined, be used for driving relay, relay contacts is made to close to drive solenoid valve dispensers overflow coil and liter (or falling) magnet coil, solenoid valve dispensers is turned on or off, the stretching or contract of hydraulic control oil cylinder, interlock is connected between the double-shaft tilt angle sensor of both sides, the conversion of both sides double-shaft tilt angle sensor mode of operation is completed by interlock, fender guard is connected between relay and electromagnetic valve, being used for detecting hydraulic ram stretches to PTO Power Take Off during end position, play a protective role.
Described interlock is two remote proximity switches (or travel switch).
Described fender guard is two proximity switches.
During use, two double-shaft tilt angle sensors are arranged on hand steered tractor, the hydraulic ram that solenoid valve dispensers is elevated with control trac. is connected, when one of them double-shaft tilt angle sensor detects that walker tractor lopsidedness angle is greater than 7 ° (7 ° can ensure that trac. jolts time can not misoperation), this side senser conducting, being amplified by relay secondary drives electromagnetic distribution valve to make hydraulic work system, hydraulic ram extends, walker tractor achieves balance, balance casterangle sensor disconnects, hydraulic closure system.Adopt two remote proximity switches (or travel switch) to identify the position of oil cylinder, ensure side cylinder efficient when walker tractor tilts, opposite side does not work, and causes walker tractor entirety to raise in order to avoid two side cylinders work simultaneously; When trac. angle of inclination reaches maxim 21 °, the proximity switch be arranged on below oil cylinder connects action and forces hydraulic closure system, thus protection hydraulic ram be unlikely hydraulic efficiency pressure system overwork cause damage, otherwise then anti-.
The power that walker tractor combustion engine exports, drive hydraulic oil pump, by the automatic adjustment of electronic automatic balance system, control multipath hydraulic electromagnetic valve and connect and close, make left and right hydraulic ram stretch or contract, reach hillside fields walker tractor center of gravity and remain at state of equilibrium.
Beneficial effect of the present invention
After walker tractor being installed electronic automatic balance system, during by hillside fields, by electronic automatic balance system, make left and right hydraulic ram stretch or contract, reach hillside fields walker tractor center of gravity and remain at state of equilibrium, have easy to operate, balance advantage accurately.
