And tree-remover technical field.
Background technology
Nursery implantation technique, which removes, can make full use of the sunlight-heat reaources in nursery place, seedling stage drought is avoided to freeze natural calamity, carry
Outside the multiple crop index of high crops, also there is the compensating action to weather and the comprehensive benefit for shifting to an earlier date plant growth, be China
Future ensures one of the important means of agricultural product supply security.In recent years, with the continuous improvement of China's agriculture production technology, move
The continuous expansion continued to increase and transplant area of crop specie is planted, nonirrigated farmland seeding transplant machine starts progressively to step into vast agricultural kind
The visual field at family is planted, becomes very important mechanization equipment in the seedling transplanting production operation of nonirrigated farmland.However, current Farm Machinery Market
On, the pitch of seeding transplant machine, left-right balance hydraulic control system generally existing structure are unreasonable, spare and accessory parts quantity compared with
It is more, connecting pipeline is complex, assemble installation it is single, stability is poor, maintaining is inconvenient, processing and manufacturing is difficult, is produced into
The shortcomings of this is higher, narrow scope of application.When hillside, small plot operation, due to cannot be according to landform, landforms and ridge High variation
Corresponding adjusting is made, thus the requirement of crops transplanting spacing in the rows, line-spacing and depth cannot be met substantially, to the vast of knob
Farmer brings inconvenience.Therefore, optimize the overall structure of seeding transplant machine hydraulic control system, reduce the kind of its spare and accessory parts
With quantity, simplify its connecting pipeline, improve its assemble Installation Flexibility, enhance its stability, its more convenient maintaining, drop
Low its manufactures assembly difficulty and cost, to expand its scope of application extremely urgent.The present invention will be that hills or even plains region are real
Now the mechanization transplanting of the crops such as vegetables, flowers, tobacco, beet, cotton, corn, rape lays good substance base
Plinth, and to mitigation transplanting operation labor intensity, improvement crops transplanting quality, raising rural labor productivity effect with important existing
Sincere justice.
The content of the invention
It is contemplated that optimize the overall structure of seeding transplant machine hydraulic control system, the kind sum number for reducing its spare and accessory parts
Amount simplifies its connecting pipeline, improves it and assemble Installation Flexibility, enhance its stability, facilitate its maintaining, reduce its manufacture
Assembly difficulty and cost expand its scope of application, be hills or even plains region realize such as vegetables, flowers, tobacco, beet,
The mechanization transplanting of the crops such as cotton, corn, rape lays good material base, and strong to mitigating transplanting operation work
Degree, improvement crops transplanting quality, raising rural labor productivity effect have important practical significance.
Technical scheme：Including fuel tank 1, oil filter 2, oil pump 3, synchronous velocity control valve 4, overflow valve I 5, three
Position four-way valve I 6, one-way hydraulic lock 7, piston cylinder I 8, load I 9, load II 10, piston cylinder II 11, three-position four-way valve II 12 overflow
