Изобретение относитс к сельскохоз йственному машиностроению, в частности к системам управлени самоходных машин дл уборки технических культур. The invention relates to agricultural machinery, in particular, to control systems of self-propelled machines for harvesting industrial crops.
По основному авт. св. № 631101 известно устройство дл управлени самоходной сельскохоз йственной машины, включающее след щую систему автоматического управлени с копирующими щупами, распределителем и силовым гидроцилиндром, систему ручного управлени с узлом дистанционного управлени , св занными с силовым гидроцилиндром маслопроводами с обратными клапанами, с которыми соединен элемент с логической функцией И 1.According to the main author. St. No. 631101, a device for controlling a self-propelled agricultural machine is known, including a follow-up automatic control system with copy probes, a distributor and a power cylinder, a manual control system with a remote control unit connected to the power hydraulic cylinder of oil lines with non-return valves, to which the element is connected to a logic function and 1.
Недостатком известного устройства вл етс то, что переключение элемента с логической функцией И происходит только при больщих потоках рабочей жидкости. Кроме того, наличие механической св зи копирующих щупов и управл емых колес, котора имеет люфты в звень х, снижает точность автоматического вождени .A disadvantage of the known device is that switching of an element with a logical function of AND occurs only at high flows of the working fluid. In addition, the mechanical connection of the copy probes and steering wheels, which has gaps in the links, reduces the accuracy of automatic driving.
Целью изобретени вл етс обеспечение работоспособности устройства при малых потоках рабочей жидкости.The aim of the invention is to ensure the operability of the device at low flows of the working fluid.
Эта цель достигаетс тем, что устройство содержит дроссели с обратными клапанами, установленными в маслопроводах.This goal is achieved by the fact that the device contains throttles with non-return valves installed in the oil lines.
Элемент с логической функцией И и обратные клапаны размещены в общем корпусе с проточками, выполненными по диаметру шаров.The element with the logical function And and the check valves are placed in a common housing with grooves made on the diameter of the balls.
След ща система автоматического вождени содержит насос-дозатор, кинематически св занный с копирующими щупами.The following automatic driving system comprises a metering pump kinematically associated with the copy probes.
На чертеже представлена схема предлагаемого устройства дл управлени самоходной сельскохоз йственной машиной.The drawing shows the scheme of the proposed device for controlling a self-propelled agricultural machine.
Устройство дл управлени самоходной сельскохоз йственной машиной состоит из след щей системы автоматического управлени с копирующими щупами 1, распределителем 2 и гидроцилиндром 3 управл емых олес 4, узла дистанционного ручного управлени 5 с рулевым колесом 6, распределителем 7 и насосом-дозатором 8, переключающего блока 9, собранного из двух обратных клапанов 10 и элемента 11 с логической функцией И. Корпус 12 переключающего блока 9 имеет две проточки с седлами под щары 13. Между шарами 13 расположенThe device for controlling a self-propelled agricultural machine consists of an automatic control system with copy probes 1, a distributor 2 and a hydraulic cylinder 3 controlled oles 4, a remote manual control unit 5 with a steering wheel 6, a distributor 7 and a metering pump 8, a switching unit 9 assembled from two check valves 10 and element 11 with logic function I. The housing 12 of the switching unit 9 has two grooves with seats under the gaps 13. Between the balls 13 is located
