Description

Прием одновременной обработки междур дий и р дков пропашных культур и устройство попарно расположенных поворотных лап, работающих в сочетании со стрельчатыми неподвижными лапами, известен; известно также применение синхронизатора скоростей, включаемого в работу от вала отбора мощности трактора и ог приводного колеса прицепной машины, сообщающего движение рабочим органам. Недостатком их вл етс вли ние неравномерности вращени вала отбора мощности трактора на точность срабатывани поворотных лап.The reception of simultaneous processing of inter-row spacing and rows of tilled crops and the arrangement of pairwise-arranged slewing legs, working in combination with lancet fixed legs, is known; It is also known to use a speed synchronizer, which is included in the operation of the tractor's power take-off shaft and on the drive wheel of the trailed machine, which imparts movement to the working bodies. Their disadvantage is the effect of the uneven rotation of the tractor's power take-off shaft on the accuracy of the paws.

Предлагаемый синхронизатор не имеет этого недостатка, так как он получает гтривод мгновенно и непосредственно от ведущих колес трактора.The proposed synchronizer does not have this drawback, since it receives the drive immediately and directly from the driving wheels of the tractor.

Кроме того, в нем применено сочетание синхронизатора с включателем гидромоторов и центробежным регул тором, который приводит в движение гидронасос и исключает вли ние на работу поворотных лап вала отбора мощности трактора.In addition, it uses a combination of a synchronizer with a switch of hydromotors and a centrifugal regulator, which drives the hydraulic pump and eliminates the effect on the work of the tractor's pivot shaft.

На фиг. 1 показан агрегат сверху вид; на фиг. 2--схема спаренных поворотных лап с гидромотором и ограничите,лем оборотов; на фиг. 3- схема синхронизатора, его привода, приводов включател г-идромотороз и регул тора лап.FIG. 1 shows an assembly from the top view; in fig. 2 is a diagram of paired paws with a hydraulic motor and limit, by the turnovers; in fig. 3 is a diagram of a synchronizer, its actuator, actuators, including an r-hydromotor and paw regulator.

Агрегат состоит из рамы 7, состо щей из двух звеньев-левого и правого. Каждое звено с одной стороны крепитс к трактору, а с другой-к направл ющей. Шесть комплектов спаренных поворотных лап 2 и столько же стрельчатых 3 шарнирно закреплены на балке 4 рабочих органов. Балка 4 закреплена к раме агрегата и через систему штоков св зана с вертикальным ходовым винтом, получающим вращение от гидромотора 5 подъема и заглублени рабочих органов.The aggregate consists of a frame 7, consisting of two links — left and right. Each link is attached to the tractor on one side and a guide on the other. Six sets of paired paws 2 and the same lancet 3 are hinged on the beam 4 working bodies. The beam 4 is fixed to the frame of the unit and, through a system of rods, is connected with a vertical spindle that receives rotation from the hydraulic motor 5 for raising and lowering the working members.

Механизм спаренных поворотных лап состоит из двух валов и 7 с закреплеиньщи на них лапами 8, шестерен промежуточной передачи 9 и JO к шестерен // и 12 редуктора. Поворот осуш.ествл етс гидромотором 13, вьшолненныад в виде двух цилиндрических шестерен }4 и 15, и корпуса с крышкой. Ограничитель оборотов состоит из фрикциона 16 и трех сателлитов 17, наход шихс в зацеплении с шестерней 18, и шестернейкорпусом 19, смонтированных на валике 20. В нижней части ограничител имеетс храновой механизм 21.The mechanism of paired paws consists of two shafts and 7 with clamped paws 8 on them, intermediate gears 9 and JO gears to gears // and 12 gears. The rotation of the dryer is driven by a hydraulic motor 13, executed in the form of two spur gears} 4 and 15, and a housing with a cover. The speed limiter consists of a friction clutch 16 and three satellites 17 meshed with gear 18 and gear casing 19 mounted on a roller 20. In the lower part of the limiter there is a storage mechanism 21.

Синхронизатор выполнен из трех блоков-центрального и двух боковых (левого и правогО). Левый блок состоит из шестерен 22, 23 и 24: правый- блок из шестерен 25, 26 и 27. Левый и правый блоки нередают вращение от ведущих валов 28 тормозов через конические шестерни 29 и 30 фрикционные муфты к шестерне 31 привода включател гидромоторов поворотных лап и центробежного регул тора оборотов лап. Центробежный регул тор 32 получает движение через синхронизатор и шестерни 33 и 34. Регул тор заключен в корпус и состоит из валика 35, грузиков 36, :ползуна, пружины и штока 37 с зубом. Шток своим зубом сцепл етс с шестерней 38 золотника. При повороте золотника уменьшаете или увеличиваетс проходное отверстие дл масла, подводимого к золотнику , и тем самым мен етс количество масла, поступающего к гидромоторам спаренных лап, чем обеспечиваютс обороты лац соответственно скорости передвижени агрегата. Включатель гидромоторов приводитс во вращение от синхронизатора через гибкий вал 39 и шестерни 40 и 33 и предназначен дл подачи масла от насоса через центробежный регул тор и золотники включател к соответствующим гидромоторам спаренных поворотных лап.The synchronizer is made of three blocks - central and two side (left and right). The left block consists of gears 22, 23 and 24: the right is a block of gears 25, 26 and 27. The left and right blocks are not rotated from the driving drive shafts 28 of the brake through bevel gears 29 and 30 friction clutches to the gear 31 of the actuator of the hydraulic motors of the paws and centrifugal speed control paws. The centrifugal regulator 32 receives movement through the synchronizer and gears 33 and 34. The regulator is enclosed in a housing and consists of a roller 35, weights 36,: a slide, a spring, and a rod 37 with a tooth. The stem engages with the gear 38 of the spool with its tooth. When the spool is rotated, the through-hole for the oil supplied to the spool is reduced or increased, and thus the amount of oil supplied to the motors of the paired legs changes, thus ensuring the turns of the rolls according to the speed of movement of the unit. The switch of the motors is driven in rotation from the synchronizer through the flexible shaft 39 and gears 40 and 33 and is designed to supply oil from the pump through the centrifugal regulator and the spool switches to the corresponding hydraulic motors of the paired turning legs.
