Description

A kind of maize harvesting machine hydraulic pressure 4 wheel driven anti-slip device
Technical field
This utility model relates to maize harvesting machine field, especially a kind of maize harvesting machine hydraulic pressure 4 wheel driven anti-slip device.
Background technology
At present maize harvesting machine is front-wheel drive mostly the most on the market, trailing wheel hydro-steering, in muddy field, sandy soil ground or when mountain region operation driving force limited, walking is not easy to get rid of poverty when skidding;Mechanical Driven maize harvesting machine not only operates complexity, and does not has drive system overload protection function.Hydraulic pressure 4 wheel driven maize harvesting machine is the most simple to operate; again to field condition strong adaptability; also has drive system overload protection function; but the deficiency of existing hydraulic pressure 4 wheel driven maize harvesting machine is: when there being a pair to take turns skidding; the wheel rotor speed skidded is too fast; non-slip wheel driving force declines suddenly, and causing that vehicle is stranded can not operation.
Summary of the invention
The purpose of this utility model is to provide a kind of maize harvesting machine hydraulic pressure 4 wheel driven anti-slip device, overcomes existing harvest corn locomotive wheel easily to skid stranded problem, improves the work efficiency of maize harvesting machine.
The technical solution of the utility model is: a kind of maize harvesting machine hydraulic pressure 4 wheel driven anti-slip device, including detection control centre, variable delivery hydraulic oil pump, quantitatively forerunner's motor and variable rear-guard motor, described variable delivery hydraulic oil pump is connected with quantitative forerunner's motor and variable rear-guard motor respectively by forcing flow divider, quantitatively forerunner's motor connects two front-wheels of maize harvesting machine respectively by change speed gear box, variable rear-guard motor connects two trailing wheels of maize harvesting machine respectively by reduction box, two front-wheels and two trailing wheels are respectively equipped with velocity sensor, velocity sensor is all connected with detecting control centre, detection control centre connects forces flow divider, so that when velocity sensor detects skidding, by forcing flow divider to control distribution to quantitative forerunner's motor and the flow of variable rear-guard motor.
Described variable delivery hydraulic oil pump, quantitative forerunner's motor and variable rear-guard motor connect oil respectively and dissipate, and oil dissipates and connects electromotor.
Compared with prior art, the beneficial effects of the utility model are:
The volume adjustable hydraulic pump of this utility model hydraulic pressure 4 wheel driven anti-slip device connects quantitative forerunner's motor and variable rear-guard motor respectively by forcing flow divider.When maize harvesting machine normally travels, flow divider is forced to be equivalent to a threeway;When the velocity sensor of two front-wheel/trailing wheels of maize harvesting machine detects that skidding occurs in two front-wheels/trailing wheel, velocity sensor is to detection control centre feedback speed signal, detection control centre is averagely shunted to variable rear-guard motor and quantitative forerunner's motor by coupled pressure flow divider, the one group of wheel forcing skidding reduces rotating speed, another non-slip group wheel is due to the increase of fuel delivery, make its driving force raise, make maize harvesting machine cross skidding section.
Compared with the type of maize harvesting machine the most on the market, this utility model maize harvesting machine hydraulic pressure 4 wheel driven anti-slip device has anti-slip function, the maize harvesting machine of this utility model hydraulic pressure 4 wheel driven anti-slip device is installed, can work under the operating mode of Normal hydraulic 4 wheel driven maize harvesting machine inoperable field, realize maize harvesting machine in hillside fields, the normalization in sand ground or muddy field travel operation, significantly widening the job area of maize harvesting machine, when improve skidding, the car load of maize harvesting machine adapts to ability and self-saving ability.

Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is schematic diagram of the present utility model.With reference to Fig. 1, this utility model one maize harvesting machine hydraulic pressure 4 wheel driven anti-slip device includes detecting control centre 1, variable delivery hydraulic oil pump 2, quantitative forerunner's motor 3 and variable rear-guard motor 4.Variable delivery hydraulic oil pump 2 is connected with quantitative forerunner's motor 3 and variable rear-guard motor 4 respectively by forcing flow divider 5.Quantitatively forerunner's motor 3 connects two front-wheels of maize harvesting machine respectively by change speed gear box.Variable rear-guard motor 4 connects two trailing wheels of maize harvesting machine respectively by reduction box.Two front-wheels and two trailing wheels are respectively equipped with velocity sensor.Velocity sensor is all connected with detecting control centre 1.Detection control centre 1 connects forces flow divider 5, to control two front-wheels and the rotating speed size of two trailing wheels that are connected with quantitative forerunner's motor 3 and variable rear-guard motor 4.
Described variable delivery hydraulic oil pump 2, quantitative forerunner's motor 3 and variable rear-guard motor 4 connect oil respectively and dissipate 6, and oil dissipates 6 connection electromotors.Electromotor drives volume adjustable hydraulic pump by belt transmission.Volume adjustable hydraulic pump provides high pressure liquid force feed for whole device.In one embodiment, hydraulic oil pressure is set as 42MPa.High pressure liquid force feed is supplied respectively to quantitative forerunner's motor 3 and variable rear-guard motor 4 by forcing flow divider 5.Force to be failure to actuate under flow divider 5 normality, be equivalent to the function of a threeway, quantitative forerunner's motor 3 and variable rear-guard motor 4 and control two front-wheels and two rear wheel rotation speed couplings, adaptive streaming respectively.Quantitatively forerunner's motor 3 connects change speed gear box, and drives two front-wheels by semiaxis, hub reduction gear;Variable rear-guard motor 4 connects reduction box, and by two trailing wheels of rear bridge driven.Detection control centre 1 automatically controls the action forcing flow divider 5 according to front and back wheel speed conditions, thus realizes automatically controlling of vehicle slip.
When ground attaching coefficient continues to reduce, when skidding occurs in wheel, the rate signal of two front-wheel/trailing wheels is fed back to detection control centre 1 by velocity sensor, and detection control centre 1 controls to force flow divider 5 to be opened, and averagely shunts quantitative forerunner's motor 3 and variable rear-guard motor 4, front and back motor flow is equal, the one group of wheel forcing skidding reduces rotating speed, and another non-slip group wheel is due to the increase of fuel delivery so that it is driving force raises, vehicle is hauled out skidding section, thus realizes getting rid of poverty saving oneself.Under transition operating mode, forerunner's pattern, rear motor can be switched to be at zero-displacement condition with hand switch, not only increase speed, and save energy consumption.
Compared with the type of maize harvesting machine the most on the market, this utility model maize harvesting machine hydraulic pressure 4 wheel driven anti-slip device has anti-slip function, the maize harvesting machine of this utility model hydraulic pressure 4 wheel driven anti-slip device is installed, can work under the operating mode of Normal hydraulic 4 wheel driven maize harvesting machine inoperable field, realize maize harvesting machine in hillside fields, the normalization in sand ground or muddy field travel operation, significantly widening the job area of maize harvesting machine, when improve skidding, the car load of maize harvesting machine adapts to ability and self-saving ability.
