Изобретение относитс к сельскохоз йственному машиностроению, а именно к устройствам дл навешивани сельскохоз йственных орудий на трактор.FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to devices for hanging agricultural implements on a tractor.

Известно навесное оборудование трактора , содержащее механизм навески, имеющий центральную т гу с упругим элементом и гидросистему, включающую гидронасос , распределитель, золотник регул тора положени навешенных орудий и силовой гидроцилиндр 1.A tractor attachment is known, which contains a hinge mechanism, having a central body with an elastic element and a hydraulic system, including a hydraulic pump, a distributor, a spool of a mounted position adjuster, and a power hydraulic cylinder 1.

Недостатком известного устройства вл етс то, что подъем навешенных сельскохоз йственных орудий происходит с запаздыванием вследствие деформации упругого элемента центральной т ги механизма навески , что приводит к снижению производительности труда.A disadvantage of the known device is that the lifting of the mounted agricultural implements occurs with a delay due to the deformation of the elastic element of the central linkage of the linkage mechanism, which leads to a decrease in labor productivity.

Цель изобретени - повышение производительности труда путем сокращени времени на подъем навешенных сельскохоз йственных орудий.The purpose of the invention is to increase labor productivity by reducing the time required for raising mounted agricultural implements.

Эта цель достигаетс тем, что гидросистема снабжена клапаном и дополнительным гидроцилиндром, установленным на центральной т ге механизма навески параллельно упругому элементу и соединенным одной из своих рабочих полостей со сливом и через клапан с другой рабочей полостью , при этом клапан св зан с бесштоковой полостью силового гидроцилиндра и с распределителем.This goal is achieved by the fact that the hydraulic system is equipped with a valve and an additional hydraulic cylinder mounted on the central linkage mechanism parallel to the elastic element and connected to one of its working cavities with the drain and through the valve to another working cavity, the valve being connected to the rodless power cylinder. and with distributor.

На чертеже схематично изображено навесное оборудование трактора в виде гидросистемы и механизма навески, в плане.The drawing schematically shows the mounted equipment of the tractor in the form of a hydraulic system and a hitch mechanism, in plan.

Навесное оборудование трактора содер10 жит механизм 1 навески, имеющий центральную т гу 2 с упругим элементом 3 и гидросистему, включающую гидронасос 4, распределитель 5, золотник 6 регул тора положени навешенных орудий, силовойThe tractor's hinged equipment contains a hinge mechanism 1, having a central gear 2 with an elastic element 3 and a hydraulic system including a hydraulic pump 4, a distributor 5, a spool 6 of the mounted positioner, power tools

15 гидроцилиндр 7, клапан 8, дополнительный гидроцилиндр 9 и каналы 10-13. Дополнительный гидроцилиндр 9 установлен на центральной т ге 2 параллельно упругому элементу и соединен одной из своих полостей с помощью гидролинии 13 со сливом15 hydraulic cylinder 7, valve 8, additional hydraulic cylinder 9 and channels 10-13. An additional hydraulic cylinder 9 is installed on the central tube 2 parallel to the elastic element and is connected to one of its cavities by means of a hydroline 13 with a drain.

Claims

and through valve 8 with a different working cavity. The valve 8 is connected to the rodless cavity of the power cylinder 7 connected by channel 11 to the bis valve 5, distributor 5, which is connected to the rod cavity of the power cylinder 7 by hydraulic line 12. Hydraulic line 4 is connected to the valve 6 by the hinged equipment of the tractor as follows. The oil from the hydraulic pump 4 through the valve 5 at the neutral position of the spool 6 (as shown in the drawing) goes to the drain. The power cylinder 7 is in this case in a fixed position. The working cavities of the additional hydraulic cylinder 9 of the central gearbox gi 2 of the mounted mechanism 1 are interconnected by means of a valve 8, while the elastic element 3 of the central pulley 2 of the mechanism 1 of the suspension is unlocked. With the passage of a signal to increase traction from the sensor, for example, a power setting mechanism (not shown), the valve 6 of the positioner of the visited guns moves to the right, and the oil from the hydraulic pump 4 flows through channels 10 and 11 into the power cylinder 7, which raises the hinged mechanism 1 and simultaneously to the valve 8, which separates the working cavities of the additional hydraulic cylinder 9. The elastic element 3 of the central thrust piston 2 of the attached mechanism 1 is blocked by the hydraulic cylinder 9.. With the passage of a signal to reduce the thrust force from the power sensor, the adjustment mechanism shifts the spool 6 to the left. The working cavities of the power cylinder 7 are connected by channels 12 and 13 with the drain, and the power cylinder 7 enters a floating state. Due to the pressure drop in the channel 11, the valve 8 connects the working cavities of the additional hydraulic cylinder 9. The elastic element 3 of the central link 2 of the attached mechanism I is unlocked. Thus, due to the blocking of the elastic element 3 by an additional hydraulic cylinder 9, the delay in raising the visited agricultural implements is eliminated, which ultimately leads to an increase in labor productivity. Invention formula Attachable equipment of the tractor containing a hinge mechanism having a central link with an elastic element and a hydraulic system including a hydraulic pump, a distributor, a spool of the regulator of the position of the visited guns and a power cylinder, characterized in that, in order to increase the production labor by reducing the time spent on visiting agricultural implements, the hydraulic system is equipped with a valve and an additional hydraulic cylinder mounted on the central linkage mechanism parallel to the elastic element and connected to one of its working cavities with a drain and through the valve to another working cavity. it is loaded with a brushless cavity of a power hydraulic cylinder and with a distributor.
