Description
Technical field
This utility model relates to a kind of tractor plough tool electric-control system.
Background technology
At present, tractor to plough tool control mainly have two types: one is to suppress type, and one is power position adjustment type.
Suppressing the control mode of type: the lifting of plough tool realizes with the hydraulic system descending through band two-way cylinder, plough tool is pressed into soil and lifts and can force to carry out by hydraulic system.Tractor is possible not only to realize the action control to plough tool rise and fall, but also has float function, and float function is exactly to there is not any pressure in hydraulic jack, and plough tool can be freely-movable with the change of landform.Suppress that to plough the various actions of tool in type hydraulic system and carry out be to be controlled by allotter, action bars on allotter has four positions: go up raise-position, neutral position, decline position and floating bit, neutral position is position locking bit, when needs realize plough tool rising, driving lever is stirred from neutral position upwards raise-position, stirring position the most, hydraulic cylinder displacement action is the fastest, otherwise the slowest.When plough tool arrives ideal position, driving lever is reversed neutral position, then hydraulic jack does not reoperates, and is locked in current location, the most also ensures that the position of plough tool does not reoperates, is locked in ideal position；The realization declined is as rising, and when need to decline, is stirred to decline position from neutral position by driving lever, and it is the most to stir position, and cylinder action is the fastest, and when dropping to ideal position, driving lever reverses neutral position can be locked position.Floating bit is from lock-bit, when needs make plough tool be in quick condition, from neutral position, allotter driving lever is pushed floating bit, and driving lever just can be locked in floating bit, and plough tool just can realize quick condition.Tractor is to have an operation handle at driver's cabin to the mode of operation of plough tool now, operation handle is connected with the driving lever on allotter by linkage mechanism, operation handle drives the driving lever on allotter to realize rising, declining and float function by linkage, and the realization of these actions mainly operates handle by people.
The control mode of power position adjustment type: this mode band regulates effectively and regulates with position.Power regulation is through the size of regulation power to control tilling depth, when power is set in some value, plough tool will be from earth's surface toward internal press-in, along with the degree of depth of press-in soil increases, the resistance ploughed will incrementally increase, when power equal in magnitude reached and arrange, tilling depth then will not be further added by, suddenly become fine and close when running into soil property, when causing resistance to increase, in order to ensure the balance of power, plough tool then can the most up be lifted, and reduces resistance by reducing tilling depth, until the size of the power of resistance and setting reaches balance.Power regulates plough tool exactly and resistance is increased or decreased by strengthening tilling depth or reduction tilling depth, is a kind of shaping modes of resistance and the size balance of the power of setting.This shaping modes is to realize action by a mechanical force governor motion in hydraulic system, operation handle in operating room is connected with the regulation handle of mechanical force governor motion by linkage, operation handle carries out action by the regulation handle of linkage driving mechanical power governor motion, and power regulation handle is in different positions and represents the size of different power.Position regulation is with to suppress type similar, it is through setting the position of plough tool to ensure tilth, position regulation handle in operating room is connected with the mechanical position governor motion of hydraulic system by linkage, when position regulation handle is in minimum position, plough tool is lifted to peak, when position regulation handle is in maximum position, plough tool drops to minimum point.Regulation handle is in different positions, and plough tool is then adjusted to corresponding position.Machinery position governor motion and mechanical force governor motion be do together with a kind of mechanism, need to regulate position handle when needs power regulate and be adjusted to maximum and then regulate power and regulate handle, need also exist for that power is regulated handle when needs position regulates and be adjusted to maximum.
Either suppress type or power position adjustment type, the common defect is both had to be exactly: complex operation, especially when plough tool lift put down again time, plough tool can not return to the position before lifting, need regulation of manually taking your time, efficiency is low, especially has the place of hard requirement to tilling depth at those, and the impact on efficiency becomes apparent from.

When described load resistance monitoring means 03 monitors when described head resistance becomes big or during described nose towing power deficiency, described load resistance monitoring means 03 transmits a signal to described control unit 06, described control unit 06 issues instructions to described rising electrically-controlled valve 011 and controls the rising of plough tool after receiving signal, tilth is reduced by plough tool rising, to discharge load, make the value that resistance returns to normally to work to ensure being normally carried out of work, the minimum of normal work is arranged in described control unit (this value can be configured by described guidance panel)；When described nose towing power is less than arranging the resistance of value or described head higher than when arranging value, described control unit 06 can control described rising electrically-controlled valve 011, plough tool is made to increase, when resistance or pull strength return to normal value, described control unit 06 can control described decline electrically-controlled valve 012, makes plough tool return to the position that described control unit 06 is remembered；
Force lifting function
Described control panel 05 is forced to lift button directly to signal to described control unit 06, described control unit 06 directly controls described rising electrically-controlled valve 010, plough tool is made to be raised to maximum position, when closing pressure lifting function, described control unit 06 receives closedown pressure and lifts signal, control described decline electrically-controlled valve 012, make plough tool return to the plough tool position that described control unit 06 is remembered；If the position of described lift arm 01 is not remembered by described control unit 06, when described control unit 06 receive the closedown that described guidance panel 05 is given force to lift signal time, described lift arm 01 is still within extreme higher position, and the change of any position does not occur.
