Description
(54) ГИДРАВЛИЧЕСКАЯ СИСТЕМА ПОЧВООБРАБАТЫВАЮЩИХ (54) HYDRAULIC SOIL PROCESSING SYSTEM
1one
Изобретение относитс к области сельскохоз йственного машиностроени , в частности к устройствам, обеспечивающим соединение почвообрабатьшаю- g щего оруди с трактором.The invention relates to the field of agricultural engineering, in particular, to devices that connect the soil-tillage tool with the tractor.
Известна гидравлическа система почвообрабатывающих агрегатов, содержаща гидроцилиндры дл подъема и опускани рабочих органов и предохра- |Q нительные гидроцилиндры, соединенные трубопроводом с гидроаккумул тором ГнThe known hydraulic system of tillage units, containing hydraulic cylinders for raising and lowering the working bodies and safety valves, connected by pipeline to hydraulic accumulator G
Дл управлени гидроцилиндрами подъема и опускани рабочих органов в этом почвообрабатывающем агрегате используетс .ходовой клапан, установленный на тракторе, снабженный автоматическим возвратным уст)Ойством, перевод щим ходовой клапан в нулевое роложение в конце подъема или опуска- ни рабочих органов.To control the hydraulic cylinders for raising and lowering the working bodies in this tillage unit, a gate valve installed on the tractor, equipped with an automatic return valve, is used.
Недостатком такой гидравлической системы вл етс резкое, скачкообразное возрастание давлени жидкости в -в системе при включени х ходового клапа на, что приводит к преждевременному возвращению клапана в исходное положение , и тракторист, чтобы этого не , .происходило, вынужден посто нно удер АГРЕГАТОВThe disadvantage of such a hydraulic system is a sharp, abrupt increase in fluid pressure in the system when the running valve is turned on, which leads to a premature return of the valve to its original position, and the operator, so that this does not happen, is forced by the constant
живать рычаг управлени клапаном в положении на подъем.the valve control lever is in the up position.
Целью изобретени вл етс повыше-; ние надежности и облегчение обслуживани гидросистемы.The aim of the invention is to increase; improvement of reliability and ease of maintenance of the hydraulic system.
Это достигаетс тем, что напорна магистраль гидроцилиндра подъема и опускани рабочих органов соединена с трубопроводом предохранительных гидроцилиндров, посредством поршневого золотника.This is achieved by the fact that the pressure line of the hydraulic cylinder for raising and lowering the working bodies is connected to the pipeline of safety hydraulic cylinders by means of a piston valve.
На чертеже Представлена схема пред лагаемой гидравлической системы.The drawing shows a diagram of the proposed hydraulic system.
Гидравлическа система включает гидроцилиндр 1 подъема и опускани рабочих органов, напорную магистральThe hydraulic system includes a hydraulic cylinder 1 of raising and lowering the working bodies, a pressure line
2,предохранительные гидроцилиндры2, safety cylinders
3,трубопровод 4, гидроаккумул тор 5 и поршневой золотник 6. Дл управлени гидроцилиндром 1 подъема и опускани рабочих органов служит ходовой клапан 7. Зар дка гидросистемы предохранительных гидроцилиндров 3 и гидроаккумул тора 5 от напорной магистрали 2 производитс через Запорный клапан 8. 3, pipe 4, hydroaccumulator 5 and piston spool 6. To control the hydraulic cylinder 1 to lift and lower the working bodies, the running valve 7 serves.
