Driving system of seedling transplanter

Abstract

The invention relates to a driving system of a seedling transplanter, the driving system includes a travelling driving hydraulic system and a seedling box lifting energy recovery hydraulic system, the travelling driving hydraulic system includes a driving main loop, an oil compensating loop and a cooling loop; a front wheel plunger pump and a rear wheel plunger pump are driven to work by an engine via a belt, the front wheel plunger pump and the rear wheel plunger pump are swashplate type, the size and the direction of the dip angle of a swash plate can be regulated by change of displacement, oil-suction direction and oil pressing direction of the pumps, the front wheel plunger pump and the rear wheel plunger pump have dual functions of change of flow rate and direction, a power element of the seedling box lifting energy recovery hydraulic system is gear pump driven by the engine, the oil outlet of the gear pump is connected with a three-position four-way directional control valve, the three-position four-way directional control valve is used to control the flow direction of hydraulic oil so as to control lifting and descending of a seedling box, a reversing valve is O-type meso-position function, and is used to lock the position of an oil cylinder, an oil outlet of a rodless cavity of a lifting oil cylinder is equipped with a two-position solenoid directional valve which is used to change the direction of the hydraulic oil, and an energy accumulator is mounted on one oil outlet of the reversing valve to store and release energy.

Description

technical field [0001] The invention relates to a driving system of a rice transplanter, belonging to the technical field of the driving system of a rice transplanter. Background technique [0002] With the implementation of the country's "Thirteenth Five-Year Plan", hydraulic transmission and electric transmission technologies are gradually being used in the field of agricultural machinery, and agricultural machinery products are gradually developing towards automation and intelligence. It has also become an inevitable development trend. [0003] The existing high-speed rice transplanter has a series of advantages such as high efficiency and good planting quality. It has been working in paddy fields with poor environment for a long time and can basically meet the requirements of paddy field work, but it also has the following disadvantages: [0004] 1) Multi-stage gears and transmission shafts are used to transmit power, the transmission system is complex and heavy, the la...

AI Technical Summary

Problems solved by technology

[0004] 1) Multi-stage gears and transmission shafts are used to transmit power, the transmission system is complex and heavy, the layout is fixed and single, and the speed adjustment range is small

[0005] 2) The mass of the whole machine is relatively large, which does not meet the demand for lightweight

[0006] 3) Can not store excess kinetic energy or potential energy of the recovery system, which is not conducive to energy saving and environmental protection

[0007] 4) The driving part of rice transplanting is mechanical transmission, the transmission system is complicated, and the speed cannot be adjusted steplessly, which is not conducive to control

[0008] 5) It is not conducive to the realization of automation and intelligent control
