Abstract

The damping device is for hydraulic systems for soil working implements, esp. ploughs, to allow damping of the pressure peaks appearing in the hydraulic system. There is a piston plunger with one piston side connected to the pressure line to the operating cylinder for the excavation while the opposite piston side is connected to the pressure line for the overload system of the plough body. The overload system can be filled with hydraulic oil via a cut-off valve and is adjusted to a smaller pressure than is necessary for digging the plough in the operating cylinder.

Description

(54) ГИДРАВЛИЧЕСКАЯ СИСТЕМА ПОЧВООБРАБАТЫВАЮЩИХ (54) HYDRAULIC SOIL PROCESSING SYSTEM

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.
