Description
св занной с рычагом 10 управлени трансмиссией 11 рабочих органов сельскохоз йственного агрегата.connected with the transmission control lever 10 of 11 working bodies of the agricultural unit.
Педаль 3 и рычаг управлени трансмиссией снабжены возвратными пружинами 12 и 13.Pedal 3 and transmission control lever are equipped with return springs 12 and 13.
Устройство снабжено также датчиками 14 контрол перегрузки рабочих органов, подключенными к блоку контрол 15 перегрузки , выход которого подключен к обмотке электромагнита 1.The device is also equipped with sensors 14 controls the overload of the working bodies connected to the control unit 15 overload, the output of which is connected to the winding of the electromagnet 1.
Устройство работает следующим образом .The device works as follows.
В исходном положении обмотка электромагнита 1 обесточена и положение корпуса 8 фиксировано относительно стакана 4. При этом изменение положени рычага 10 однозначно св зано с положением педали 3, а возврат педали 3 и рычага 10 в исходное положение при сн тии усили с педали происходит под действием возвратных пружин 12 и 13.In the initial position, the winding of the electromagnet 1 is de-energized and the position of the housing 8 is fixed relative to the cup 4. At the same time, the change in the position of the lever 10 is uniquely related to the position of the pedal 3, and the return of the pedal 3 and the lever 10 to the initial position when the force is removed from the pedal occurs under the action of return springs 12 and 13.
При работе агрегата в нормальном режиме устройство находитс в положении, показанном на фиг. 2.When the unit is operating in normal mode, the device is in the position shown in FIG. 2
При возникновении перегрузок рабочих органов датчики 14 подают сигнал на блок контрол 15 и на выход последнего подаетс электрическое напр жение, в результате чего корь электромагнита перемещает запорный шток 5, сжима пружину-6. Шарики 7 смещаютс внутрь стакана 4 и втора штанга телескопической т ги с корпусом 8 под действием пружины 13 перемещаетс по стакану 4, а рычаг 10 устанавливаетс в нерабочее положение (фиг. 3).When overloading of the working bodies occurs, the sensors 14 send a signal to the control unit 15 and an electrical voltage is applied to the output of the latter, as a result of which the electromagnet bark moves the locking rod 5, compressing the spring-6. The balls 7 are displaced inside the cup 4 and the second rod of the telescopic rod with the housing 8 is moved by the action of the spring 13 along the glass 4, and the lever 10 is set to the non-operating position (Fig. 3).
Дл повторного пуска рабочего органа в работу снимают управл ющее усилие оператора с педали 3. При этом под действиемTo restart the working body, the control effort of the operator is removed from the pedal 3. At the same time, under the action of
пружины 12 т га 2 смещаетс в исходное положение, отверсти с шариками в боковой стенке стакана 4 совмещаютс с кольцевой проточкой корпуса 8 и шарики под воздействием конусной поверхности запорного штока 5 и пружины 6 вход т в кольцевую проточку корпуса 8 и фиксируют телескопическую т гу в исходном положении (фиг. 1). После этого агрегат готов к повторному включению рабочих органов.The springs 12 tons ha 2 are displaced to their original position, the holes with balls in the side wall of the glass 4 are aligned with the annular groove of the housing 8 and the balls under the influence of the conical surface of the locking rod 5 and the springs 6 enter the annular groove of the housing 8 and fix the telescopic traction in the original position (Fig. 1). After that, the unit is ready to re-enable the working bodies.
Такое выполнение устройства повышает надежность защиты рабочих органов сельскохоз йственного агрегата от перегрузок и сокращает врем работы рабочих органовSuch an embodiment of the device increases the reliability of protection of the working bodies of the agricultural unit against overloads and reduces the working time of the working bodies.
