(54) САМОЗАГРУЖАЮЩИЙСЯ СКРЕПЕР KoHUbf двуплечих рычагов 8 посредством uiaровых опор to. и пальцев И сое линемЕ, со стойками 7 рамы, а задние концы посредством шарнира 12 - со штоками гидроцилнндров 13 наклона, корпуса которых шарнирно св заны с задними концами боковых балок 4. На боковых стенках кОвша смонтированы распорки 14 с .продольными прорез ми 15 под задние концы двуплечих рычагов 8. Задн   часть несущей рамы 3 л естко соединена с трактором 16. Между кронштейнами 17 и 18, размещенными соответственно на задней стенке ковша 2 и тракторе 16, шарнирно установлен гидроцилиндр 19 изменени  угла резани . Длина каждой прорези 15 обеспечивает полное поднимание и опускание ковша 2 гидроцилиндрами . 13,а поперечный ее размер ограничивает .скручивание или поворот вокруг продольных осей двуплечих рычагов 8, Например, размерное соЬтпошёние может допускать поворачивание двуплечих рычагов относительно их продольных осей на угол около (см. фиг. 4). Таким образом; ковш можно наклон ть на угол до 5° относительно рамы скрепера . При незаполненном ковше в транспортном положении (сплошна  лини  иа фиг.2) удлинением, двух гидрйцилиндров наклона 13 вызываетс  наклон ковШа вперед. Режуща  кромка ковша вхо.дит в. грунт обычным образом (промежуточна  пунктирна  лини  на фиг. 2). Когда же гидроцилиндры 13 удлин ютс  дл  опускани  задних концов двуплечих рычагов 8, то передний конец ковша, опускаетс  вместе с шарнирами 9, на которых удерживаетс  ковш. Дл  наклона ковша вбок гидроцилиндры 13 привод тс  в действие в противоположны/ направлени х . Как при горизонтальном, так и при наклонном. положени .х ковша задний конец ковша можно опускать одновременно с установлением его в положение копани  путем соответствуюп1его удлинени  гидроциликдра 19 (штрих-пунктирна  лини  на фиг. 2). Формула изобретени  Самозагружающийс  скрепер, включающий трактор, несущую раму, жестко соединенную задней частью с трактором, а передней частью щарнирно смонтированную на управл емой колесной паре, шарнирно подвешенный к несущей раме ковш с режущим ножом и гидроцилиндры управлени  ковшом, отличающийс  тем, что, с целью увеличени  производительности работы .скрепера путем уменьшени  сопротивлени  резанию, рама выполнена из охватывающих ковш в плане элементов, боковые из которых в передней их части имеют стойки, а подвеска ковша выполнена из шарнирно св занных с ним двуплечих рычагов, один, конец каждого из которых посредством шаровой опоры соединен с соответствующей стойкой рамы, а другой посредством гидроцилиндра шарнирио св зан с задней частью рамы, при этом на боковых стенках ковша смонтированы распорки с продольными прорез ми, через которые пропущены двуплечие рычаги.

(54) SELF-LOADING SCRAPER KoHUbf two-arm levers 8 with uiarovyh supports to. fingers and soles, with uprights 7 frames, and the rear ends by means of a hinge 12 — with tilt rods 13, the bodies of which are pivotally connected to the rear ends of the side beams 4. On the side walls of the posts, spacers 14 are mounted with longitudinal slots 15 under the rear ends of the double shoulders 8. The rear part of the carrier frame is 3 liters rigidly connected to the tractor 16. Between the brackets 17 and 18, placed respectively on the rear wall of the bucket 2 and the tractor 16, the hydraulic cylinder 19 for changing the cutting angle is hinged. The length of each slot 15 provides a full raising and lowering of the bucket 2 hydraulic cylinders. 13, and its transverse size limits twisting or turning around the longitudinal axes of two shoulders 8, For example, dimensional sawing may allow the two shoulders to rotate relative to their longitudinal axes by an angle of about (see Fig. 4). In this way; the bucket can be tilted up to 5 ° relative to the scraper frame. When the bucket is unfilled in the transport position (solid line in FIG. 2) by lengthening the two hydraulic cylinders of inclination 13, the bucket tilts forward. The cutting edge of the bucket enters. soil in the usual way (intermediate dotted line in Fig. 2). When the hydraulic cylinders 13 are lengthened to lower the rear ends of the double-arm levers 8, the front end of the bucket is lowered together with the hinges 9, on which the bucket is held. For tilting the bucket sideways, the hydraulic cylinders 13 are driven in opposite / directions. Both at horizontal and at inclined. The bucket position. The rear end of the bucket can be lowered at the same time as it is set to the digging position by a corresponding extension of hydraulic cylinder 19 (dash-dotted line in Fig. 2). The claims of the Self-loading scraper, including a tractor, a carrying frame, rigidly connected with the rear part to the tractor, and a front part that is pivotally mounted on a controlled pair of wheels, a bucket with a cutting knife and the control cylinders of the bucket, which is attached to a supporting frame, with a cutting knife and a single cylinder that is controlled by a wheelbarrow, is attached with a cutting blade. increasing the productivity of the scraper by reducing the cutting resistance, the frame is made of covering elements in terms of the bucket, the side parts of which have racks in the front parts and the suspension of the bucket It consists of two double-arm levers articulated with it, one end of each of which is connected to a corresponding frame by means of a ball and another is connected to the rear part of the frame by means of a hydraulic cylinder, with spacers with longitudinal slots mounted on the side walls of the bucket, through which the two shoulders are leveraged.
