Description
Известны устройства д.т автоматической настройки режима работы гидроувеличител сцепного веса трактора, включающие гидравлические датчики, приемники и запирающие устройства. Недостатком таких устройств вл етс то, что устанавливаемое трактористом вручную давление подпора в начале гона не вл етс оптимальным в каждой точке. Это приводит к недогрузке колес трактораОписываемое устройство отличаетс от известных тем, что к раме навесного оруди при помощи ходового винта закреплен гидроцилиндр , полость которого сообщаетс с приемником управлени давлеFfHeM подпора, а щток порщн гидроцилиндра прикреплен к стойке копирг навесного оруди . Предлагаемое устройство обеспечивает передачу на трактор величины реакции почвы на копирующие органы навесного оруди .Devices are known for the automatic adjustment of the operating mode of the tractor’s hydraulic enlarger weight, including hydraulic sensors, receivers and locking devices. The disadvantage of such devices is that the manually set pressure of the tractor driver at the beginning of the rut is not optimal at each point. This leads to underloading of tractor wheels. The described device differs from those known in that a hydraulic cylinder is fixed to the frame of the mounted gun with a lead screw, the cavity of which communicates with the backpressure pressure control receiver, and the cylinder of the hydraulic cylinder is attached to the rack of the mounted gun. The proposed device provides the transmission to the tractor of the magnitude of the reaction of the soil to the copying organs of the mounted implement.
На чертеже представлена принципиальна схема устройства.The drawing shows a schematic diagram of the device.
На навесном орудии установлен гидроцилиндр-датчик /, корпус которого при помощи ходового винта 2 св зан с рамой 3 оруди . Шток поршн гидроцилиндра соединен со стойкой 4 копирующего органа. Регулировка глубины обработки осуществл етс ходовым винтом. Верхн полость гидроцилиндра / сообщаетс с цилиндро.м-приемником л управлени давлением подпора, выполненным в крышке гидроувеличител сцепного веса. Давление в гидроцилиндре /, определ емое величиной реакции почвы, передаетс на толкающий плунжер 6. сл имающий через фигурную гайку 7 и колпак 8, регулировочную пружину 5 и пружину 10 предохранительного клапана. По сжатию пружин определ ют давление подпора. Геометрические параметры гидроцилиндра /, цилиндра 5 и пружин выбраны с таким расчетом, чтобы давление подпора, образуюп1еес в цилиндре // механизма заднейA hydraulic cylinder-sensor / is mounted on the mounted implement, the casing of which is connected to the frame of 3 guns by means of a lead screw 2. The piston rod of the hydraulic cylinder is connected to the rack 4 of the copying organ. The adjustment of the depth of processing is carried out by the lead screw. The upper cavity of the hydraulic cylinder / communicates with the cylinder m-receiver of the control of the pressure of the backwater, made in the cover of the hydraulic enlarger of the coupling weight. The pressure in the hydraulic cylinder I, determined by the magnitude of the reaction of the soil, is transmitted to the pushing plunger 6, which is fed through the figure nut 7 and the cap 8, the adjusting spring 5 and the spring 10 of the safety valve. The compression of the springs determines the pressure of the overpressure. The geometrical parameters of the hydraulic cylinder /, cylinder 5 and springs are chosen so that the pressure of the sub-pressure that forms in the cylinder // mechanism of the rear
