Изобретение относитс к области строительно-дорожных машин, в частности к погрузочно-транспортным машинам.The invention relates to the field of road building machines, in particular to loading and transport vehicles.

Известен рабочий орган логрузочнотранспортных машин, содержаш,ий ковш, закрепленный на стреле, силовые цилиндры и шарнирно-рычажную систему .A working body of logos and transport vehicles is known, containing a bucket fixed on the boom, power cylinders and a hinge-lever system.

Известен также орган погрузочно-транспортной машины, содержащий ковш, шарнирно соединенный со стрелой, силовой цн-, линдр поворота ковша, соединенный с последним посредством т ги, установленный на стреле .поворотный рычаг, на который опираетс силовой цилиндр поворота ковша в месте шарнирного соединени его с т гойAlso known is the body of the loading and transport machine, which contains a bucket pivotally connected to the boom, a power tsn, a bucket turn linder, connected to the latter by means of a pull, mounted on the boom. A swivel lever, on which the bucket turn power cylinder rests at the hinge point good luck

Недостатком указанных устройств вл етс то, что дл увеличени эффективности разгрузки ковша необходимо увеличить длин промежуточной т ги и поворотной стойки, что приводит к увеличению габаритов рабочего органа.The disadvantage of these devices is that in order to increase the efficiency of unloading the bucket, it is necessary to increase the length of the intermediate thrust and turntable, which leads to an increase in the size of the working body.

Цель изобретени - повышение эффективности разгрузки ковша путем увеличени угла разгрузки.The purpose of the invention is to increase the efficiency of unloading the bucket by increasing the angle of unloading.

Достигаетс это тем, что т га выполнена в виде коромысла, шарнирно соединенного средней частью с силовым цилиндром поворота ковша, а свободным концом - с поворотным рычагом.This is achieved by the fact that the ha is made in the form of a rocker arm, pivotally connected by the middle part with the power cylinder of turning the bucket, and the free end with the swiveling lever.

При этом с целью уменьшени величины углового отклонени ковша от его исходного положени при подъеме рабочего органа оси шарниров коромысла расположены в одной плоскости, совмещенной с осью силового цилиндра поворота ковша в нижнем и верхнем исходных положени х рабочего органа.At the same time, in order to reduce the magnitude of the angular deviation of the bucket from its initial position when lifting the working element, the axes of the hinges of the rocker arms are located in one plane aligned with the axis of the power cylinder of the bucket turning in the lower and upper initial positions of the working body.

На фиг. 1 изображен -рабочий орган в нижнем крайнем положении; на фиг. 2 - то же, в верхнем крайнем положении.FIG. 1 shows the working body in the lower extreme position; in fig. 2 - the same, in the upper extreme position.

Устройство содержит ковш 1, шарнирно закрепленный на стреле 2, силовой цилиндр 3 поворота ковша, соединенный с ним посредством т ги 4, выполненной в виде коромысла , и поворотный рычаг 5. При этом плечи коромысла 4 соединены с ковшом 1 и поворотным рычагом 5 посредством шарниров 6 и 7, а промежуточна часть шарниром 8 соединена с силовым цилиндром 3 поворота ковша. Кроме того, оси шарниров 6-8 коромысла 4 расположены в одной плоскости, совмещенной с осью силового цилиндра 3 поворота ковша в нижнем и верхнем крайних положени х рабочего органа .The device contains a bucket 1, pivotally mounted on the boom 2, the power cylinder 3 rotates the bucket connected to it by means of a ty 4, made in the form of the rocker arm, and a swivel lever 5. The arms of the rocker arm 4 are connected to the bucket 1 and the rotary lever 5 by means of hinges 6 and 7, and the intermediate part of the hinge 8 is connected to the power cylinder 3 of the rotation of the bucket. In addition, the axis of the hinges 6-8 of the yoke 4 are located in the same plane, aligned with the axis of the power cylinder 3 turns the bucket in the lower and upper extreme positions of the working body.

Работает устройство следующим образом.The device works as follows.

Claims

After the bucket 1 is filled with the rock mass, the power cylinder 3 of the bucket rotation is turned and the bucket 4 returns the bucket to its initial position by means of the rocker arm 4. When lifting the bucket 1, due to the axis of the harnesses 6-8 of the yoke 4 located in the same plane, aligned with the axis of the power cylinder 3, turning the bucket in the upper and lower extreme positions of the tool body, insignificant angular deviations of the bucket (within 2 °) from its extreme position. When unloading the bucket, the rod of the power cylinder 3 extends and moves the rocker arm 4, which by means of the hinge 6 brings the bucket 1 to the unloading position. When this occurs, the movement of the swivel lever 5, connected by a hinge 7 with the rocker arm 4. This embodiment of the working body of the loading and transport machine increases the efficiency of unloading the bucket. Claim 1. Worker body of a loading / unloading machine, including a bucket, pivotally connected to the boom, power cylinder of the bucket turning, connected to it by means of traction, and a swivel lever, characterized in that with 11ll of increasing the efficiency of unloading the bucket by increasing the discharge angle, t ha is made in the form of a rocker arm, hingedly connected by the middle part with the power cylinder of the bucket turn, and with the free condom - with the rotary lever. 2. Working body - according to claim 1, characterized in that, in order to reduce the magnitude of the bucket's angular deviation from its initial position when lifting the working body, the axis of the hinges of the rocker arm are located in one plane, aligned with the axis of the power cylinder of the bucket rotation in the lower and upper starting positions of the working body.
