Изобретение относитс к устройствам дл соединени рабочих органов с част ми машин, в частности ковша экскаватора с его руко тью.The invention relates to devices for connecting working bodies with machine parts, in particular an excavator bucket with its arm.
Известно устройство дл креплени ра- 5 бочего органа гидравлического экскаватора , в котором имеетс захват с клиновым монтажным зевом и фиксируюш,ий элемент в виде пальца .A device is known for fastening a working body of a hydraulic excavator, in which there is a grip with a wedge mounting throat and a fixing element in the form of a finger.
Недостатком этих устройств вл етс ю невозможность обеспечени в процессе эксплуатации беззазорного присоединени рабочего органа, в результате чего возникающие в каждом цикле динамические нагрузки привод т к быстрому разрушению is деталей устройства.The disadvantage of these devices is the impossibility of ensuring the in-process unresponsive attachment of the working member during operation, as a result of which the dynamic loads occurring in each cycle lead to the rapid destruction of the device parts.
Известно навесное оборудование дл разработки грунта, содерл аш,ее прикрепленную к базовой машине руко ть и рабочий орган, причем на руко ти смонтирован 20 силовой цилиндр, шток которого шарнирно соединен с рычагом, а на конце руко ти установлена эксцентрикова ось, причем к рабочему органу прикреплены скобы, соответственно взаимодействующие 25 с рычагом и эксцентриковой осью 2.Known attachments for the development of soil, containing ash, its handle attached to the base machine and the working body, moreover, a 20 power cylinder is mounted on the handle, the rod of which is pivotally connected to the lever, and an eccentric axis is installed at the end of the handle clamps are attached, respectively interacting 25 with the lever and the eccentric axis 2.
Недостатком этого устройства вл етс необходимость периодической ликвидацииA disadvantage of this device is the need to periodically eliminate
зазора в соединении рабочего органа с руко тью.the gap in the connection of the working body with the hand.
Известно устройство дл соединени рабочего органа с руко тью экскаватора, содержащее шип руко ти, проушину на рабочем органе и фиксатор .A device for connecting the working member with an excavator arm is known, comprising a handle tenon, an eye on the operating member, and a lock.
Однако такое устройство недостаточно надежно вследствие того, что оно не исключает зазоры в соединени х.However, such a device is not sufficiently reliable due to the fact that it does not exclude gaps in the connections.
Цель изобретени - повышение надежности соединени .The purpose of the invention is to increase the reliability of the connection.
Это достигаетс тем, что в устройстве дл соединени рабочего органа с руко тью экскаватора руко ть снабжена шарнирно св занной с ней траверсой, на которой расположен шип, выполненный в виде клина, причем проушина и шип имеют в поперечном сечении скошенные в сторону оси их симметрии рабочие поверхности, а фиксатор выполнен в виде приводного эксцентричного кулачка.This is achieved by the fact that in the device for connecting the working body with the excavator arm, the handle is provided with a cross-arm, pivotally connected to it, on which there is a wedge shaped spike, and the eyelet and thorn have in cross section their working symmetry axis surface, and the latch is made in the form of a drive eccentric cam.
