Description
Technical field
The present invention relates to agricultural mechanical field, turning between specially a kind of achievable compact structure and highland gap structure
Change and meet the special agriculture requirement such as weeding and management operation under long-stalked crop intertillage, field management operation in the ranks and orchard tree crown
Road clearance adjustable multifunctional tractor chassis.
Background technology
In agricultural mechanization development process, the mechanization of planting industry technology is emphasis all the time, is also the master of modern agriculture
Indicate.But the not perfectly flat weighing apparatus of the development of all kinds of planting machineries, mechanization degree difference is larger, such as arable land, site preparation, sowing, wheat
The events in operation such as harvest, mechanization degree has reached higher level, and great function is served to the development for promoting planting industry production.
Some events in operation, mechanization degree is relatively low, such as field crop and fruit tree, the tillage and weeding in vegetables production and field management
Project, continues to use traditional manual work mode substantially, and labor intensity is big, low production efficiency, and the requirement with modern agricultural production is not
It is adapted, main cause is shown：（1）The scale of operation of China's agricultural production is small, and field divides thin, and hilly and mountainous land is more, landform
Complexity, large and middle tractor is difficult under crop growthing state into ground operation；（2）In recent years, the development of small-sized field-garden management machine
Comparatively fast, it is but big both for greenhouse vegetable production, it is not suitable with the field management requirement of crop field imtertilled crop；（3）Supporting intertillage
Manage equipment to lack, the especially high-clearance engine dedicated for this operation, at home substantially blank；（4）Orchard
Field management labor intensity is big, and work tool is few, and the compact type tractor of operation under tree crown can be adapted to by especially lacking.
The long-stalked crops such as corn, sorghum, the job requirements dynamic power machine such as field management, tillage and weeding at later stages leads to
The property crossed is good, and climbing property is good, and ground gap is high, can be in the ranks walking and operation；The operations such as orchard management, tillage and weeding, transport, it is desirable to drag
Machine drawing compact conformation, the road clearance is small, and complete machine is highly small, can be in normal operation under tree crown.Different operating condition, to tractor
Structural shape requirement differ greatly, be badly in need of a kind of adjustable multifunctional tractor of road clearance in production, not only meet high bar
The requirement of crop operation in the ranks, can also meet under the tree crown of orchard and manage job requirements.
For tractor, its road clearance depends primarily on the structure of chassis main frame.It is used as the core group of tractor
Into part, chassis main frame has important influence to the reliability of complete machine, stability and work in every performance, there is very big grind
Study carefully meaning and researching value.In the presence of certain defect during existing high-arch tractor operation on domestic market：One is tractor
Chassis contour dimension is larger；Two be tractor chassis gap it is low, it is impossible to be directly entered the operation of fruit tree nursery.
The content of the invention
The present invention in order to solve the problem of there is larger contour dimension and low ground gap in existing tractor chassis there is provided
A kind of road clearance adjustable multifunctional tractor chassis.
The present invention adopts the following technical scheme that realization：Road clearance adjustable multifunctional tractor chassis, including wheel

Frame lifting upper connecting rod and frame lifting lower link, frame lifting upper connecting rod and frame lifting that the front and rear sides at right two ends are hinged
The other end of lower link is hinged with wheelspacer pipe, be provided with the middle part of frame left and right ends one end be hinged with it, it is another
The frame hoist cylinder that end is hinged with wheelspacer pipe；Steering mechanism includes being arranged on turning for wheelspacer pipe front and rear sides
To oil cylinder, between being provided with the outside of two steering cylinders on the outside of the kingpin vertically placed, kingpin and steering cylinder
It is provided with the steering link being connected with both；Ground gap governor motion includes the kingpin connector fixed with kingpin, turns
Driving wheel is provided with below to vertical shaft connector, the axle center of driving wheel is provided with driving wheel bar, and driving wheel bar connects with kingpin
The ground gap regulation upper connecting rod for being hinged and being obliquely installed with both and ground gap regulation lower link, and kingpin are provided between fitting
The ground gap regulation oil cylinder being hinged with both is provided between connector and ground gap regulation lower link；Also set up at the axle center of driving wheel
There is drive motor, the decelerator being connected with both is provided between drive motor and driving wheel.
When carrying out road clearance regulation, wheel tread adjusting mechanism is adjusted by wheelspan to be stretched inside and outside hydraulic oil cylinder driving wheel distance regulating rod
Contracting, and then ground gap governor motion and the inside and outside regulation of driving wheel are driven, realize the regulation of Track width；Frame elevating mechanism passes through machine
Frame hoist cylinder driving frame lifts upper and lower link motion, relative to wheelspacer pipe, can be achieved to frame high and low position
Regulation；Steering mechanism by steering cylinder drive steering link drive kingpin rotate, and then drive ground gap governor motion and
Driving wheel is rotated, and realizes a range of deflection of driving wheel；By ground gap, gap is adjusted ground gap governor motion with adjusting hydraulic oil cylinder driving
Upper and lower link motion, and then regulation above and below driving wheel bar and driving wheel is driven, realize the regulation and support to complete machine；Drive horse
Power is provided up to for driving wheel.Overcome the problem of existing tractor chassis has larger contour dimension and low ground gap.
The adjustable range of ground gap governor motion is 200-1700mm, and the adjustable range of wheel tread adjusting mechanism is 1360-
2000mm。
When the structure design make it that the road clearance is smaller, it can be used as compact type tractor, can when the road clearance is larger
Used as high-arch tractor, possess the functions such as comprehensive steering, frame automatic adjusument, be suitable for orchard and long-stalked crop
Operation in the ranks.
Reasonable in design of the present invention is reliable, and its road clearance, wheelbase and wheelspan can adjust, and meet most of crops
Intertillage agronomy ground gap requirement and in the ranks job requirements, it is to avoid the crop damage not enough caused due to the road clearance；And knot
Structure is compact, by functional, during the operation of hillside fields, produce the discrepancy in elevation by vehicle frame or so ground gap governor motion, can make tractor on slope
Ground smooth-ride, prevents rollover, while not only meeting long-stalked crop intertillage and field management job requirements, and orchard in the ranks
Field management, weeding, tillage operation, realize the requirement of a tractor serves several purposes, reduce the species of agricultural production dynamic power machine, reduction
Production cost.
