Description
Technical field
The present invention relates to agricultural mechanical field, turn between specially a kind of achievable compact structure and highland gap structure
It changes and meets 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 technique
In agricultural mechanization development process, the mechanization of planting industry technology is the master of emphasis and modern agriculture always
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
Events in operation, the mechanization degrees such as harvest have reached higher level, play great function to the development for promoting planting industry production.
Some events in operation, mechanization degree is lower, such as tillage and weeding and field management in field crop and fruit tree, vegetables production
Project continues to use traditional manual work mode substantially, and large labor intensity, production efficiency is low, and the requirement with modern agricultural production is not
It is adapted, main cause is shown: (1) scale of operation of China's agricultural production is small, and field divides carefully, and hilly and mountainous land is more, landform
Complexity, large and middle tractor are difficult into ground operation under crop growthing state；(2) in recent years, the development of small-sized field-garden management machine
Comparatively fast, but greatly it is produced both for greenhouse vegetable, is not suitable with the field management requirement of crop field imtertilled crop；(3) matched intertillage
Equipment is managed to lack, especially dedicated for the high-clearance engine of this operation, substantially blank at home；(4) orchard
Field management labor intensity is big, and work tool is few, especially lacks the compact type tractor that can be suitble to operation under tree crown.
The long-stalked crops such as corn, sorghum, the job requirements dynamic power machine such as field management, tillage and weeding at later stages are logical
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 that drag
Machine drawing is compact-sized, and the road clearance is small, and complete machine height is small, can be in normal operation under tree crown.Different operating condition, to tractor
Structural shape require differ greatly, be badly in need of a kind of road clearance adjustable multifunctional tractor in production, not only meet high bar
The requirement of crop operation in the ranks can also meet and manage job requirements under the tree crown of orchard.
For tractor, the road clearance depends primarily on the structure of chassis main frame.Core group as tractor
At component, 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.Have the defects that when existing high-arch tractor operation on domestic market certain: first is that tractor
Chassis contour dimension is larger；Second is that tractor chassis gap it is low, the operation of fruit tree nursery can not be directly entered.
Summary of the invention
The present invention provides to solve the problems, such as that existing tractor chassis is larger there are contour dimension and ground gap is low
A kind of road clearance adjustable multifunctional tractor chassis.
The present invention is achieved by the following technical scheme: road clearance adjustable multifunctional tractor chassis, including wheel
Distance regulating mechanism, rack elevating mechanism, steering mechanism, gap regulating mechanism and rack；Wheel tread adjusting mechanism includes left and right settings
Wheelspacer pipe, the wheel distance regulating rod that front and back is distributed is installed in wheelspacer pipe, and take turns the outer end of distance regulating rod with
It is provided between wheelspacer pipe and adjusts oil cylinder with the hinged wheelspan of the two；Rack elevating mechanism includes that one end and rack are left
The hinged rack lifting upper connecting rod in the front and rear sides at right both ends and rack go up and down lower link, and rack goes up and down upper connecting rod and rack lifting
The other end of lower link and wheelspacer pipe are hinged, and it is hinged with it, another that one end is provided in the middle part of rack left and right ends
End and the hinged rack lifting cylinder of wheelspacer pipe；Steering mechanism includes that turning for wheelspacer pipe front and rear sides is arranged in
To oil cylinder, the kingpin vertically placed is provided on the outside of two steering cylinders, between kingpin and steering cylinder outside
It is provided with the steering link connecting with the two；Ground gap regulating mechanism includes the kingpin connector fixed with kingpin, is turned
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 and kingpin connect
It is provided with ground gap adjusting upper connecting rod that is hinged with the two and being obliquely installed between fitting and ground gap adjusts lower link, and kingpin
Connector and ground gap, which adjust to be provided between lower link, adjusts oil cylinder with the hinged ground gap of the two；It is also set up at the axle center of driving wheel
There is drive motor, the retarder connecting with the two is provided between drive motor and driving wheel.
When carrying out road clearance adjusting, wheel tread adjusting mechanism is adjusted overhanging in oil cylinder driving wheel distance regulating rod by wheelspan
Contracting, and then ground gap regulating mechanism and the inside and outside adjusting of driving wheel are driven, realize the adjusting of Track width；Rack elevating mechanism passes through machine
Frame lifting cylinder drives rack to go up and down upper and lower link motion, relative to wheelspacer pipe, it can be achieved that rack high and low position
It adjusts；Steering mechanism by steering cylinder drive steering link drive kingpin rotation, and then drive ground gap regulating mechanism and
Driving wheel rotation, realizes a certain range of deflection of driving wheel；Ground gap regulating mechanism adjusts oil cylinder drivingly gap adjusting by ground gap
Upper and lower link motion, and then driving wheel bar and driving wheel up and down adjustment are driven, realize adjusting and support to complete machine；Drive horse
Power is provided up to for driving wheel.Overcoming existing tractor chassis has that contour dimension is larger and ground gap is low.
The adjustable range of ground gap regulating mechanism is 200-1700mm, and the adjustable range of wheel tread adjusting mechanism is 1360-
2000mm。
When structure design is so that the road clearance is smaller, compact type tractor use can be used as, it, can when the road clearance is larger
It is used as high-arch tractor, has the functions such as comprehensive steering, rack automatic adjusument, be suitable for orchard and long-stalked crop
Operation in the ranks.
Structure of the invention design is rationally reliable, and road clearance, wheelbase and wheelspan are adjustable, meets most of crops
Intertillage agronomy gap require and in the ranks job requirements, avoid as the road clearance it is inadequate caused by crop damage；And it ties
Structure is compact, and passage capacity is good, when the operation of hillside fields, generates height difference by vehicle frame or so ground gap regulating mechanism, tractor can be made on slope
Ground smooth-ride prevents from turning on one's side, while not only meeting long-stalked crop intertillage and field management job requirements, but also orchard in the ranks
Field management, weeding, tillage operation realize the requirement of a tractor serves several purposes, reduce the type of agricultural production dynamic power machine, reduce
Production cost.
