Abstract

Изобретение может быть использовано в конструкции зерноуборочного комбай- на, бункер которого выполнен с подвижными днищем и боковой стенкой, и обеспечивает повышение надежности поворота днища и стенки при их подн тии, а также улучшение заполнени бункера зерном . Корпус 1 бункера имеет наклонное к нижнему выгрузному устройству 3 днище 9 и одностороннюю с ним боковую подвижную стенку 6, подпружиненную к днищу 9 при помощи блоков пружин 12. С днищем 9 св заны гидроцилиндры 10 двухстороннего действи дл поворота стенки 6 вокруг своего верхнего конца и днища 9 вокруг своего нижнего конца. Перед выгрузкой зерна из бункера днище 9 находитс в крайнем нижнем положении, а стенка б - в вертикальном. По мере выгрузки зерна при помощи гидроцилиндров 10 днище 9 поднимают, при этом стенка 6 также поднимаетс , прижима сь к днищу 9 со скольжением относительно него под действием блоков пружин 12. В крайнем верхнем положении днища 9 и стенки 6 их плоскости наклонены к горизонтали под углом, достаточным дл самопроизвольного ссыпа- ни зерна к устройству 3. Сопр жение днища 9 с внутренней поверхностью стенки 6 при ее подпружинивании к днищу 9 исключает заклинивающее воздействие стенки 6 в на чале процесса выгрузки зерна . 1 з.п.ф-лы, 2 ил. сл сThe invention can be used in the design of a combine harvester, the bunker of which is made with a movable bottom and side wall, and provides improved reliability of the turn of the bottom and wall when they are raised, as well as improved filling of the bunker with grain. The bunker body 1 has a bottom 9 inclined to the lower unloading device 3 and a lateral movable wall 6 which is one-sided with it, which is spring-loaded to the bottom 9 by means of spring units 12. Two-acting hydraulic cylinders 10 are connected to the bottom 9 to rotate the wall 6 around its upper end and the bottom 9 around its lower end. Before unloading grain from the hopper, the bottom 9 is in the lowest position, and the wall b is in the vertical position. As the grain is unloaded by means of hydraulic cylinders 10, the bottom 9 is raised, while the wall 6 also rises, pressing against the bottom 9 with sliding against it under the action of spring blocks 12. In the extreme upper position of the bottom 9 and the walls 6, their plane is inclined to the horizontal at an angle sufficient for the spontaneous dumping of grain to the device 3. The coupling of the bottom 9 with the inner surface of the wall 6 when it is springing to the bottom 9 eliminates the jamming effect of the wall 6 at the beginning of the process of unloading grain. 1 hp ff, 2 ill. cl

Claims

Claim

1. The hopper of the combine harvester, comprising a housing made with lateral fixed walls, a bottom inclined towards a discharge device located at the bottom of the housing, and a one-sided movable side wall with a bottom, the upper end of which and the lower end of the bottom are pivotally connected to a bottom drive for rotating the movable wall and the bottom with mutual sliding of the latter, characterized in that, in order to increase the reliability of rotation of the bottom and the movable wall in the process of raising them, as well as improve the When filling the hopper with grain, the bottom is interfaced with the inner surface of the movable wall, which is spring-loaded to the bottom, and the drive is made with two-sided action,.

2. The hopper according to claim 1, characterized in that the movable wall is spring-loaded to the 5th bottom by means of spring blocks connected to this wall by means of levers rigidly connected to it and length-adjustable rods connected to the fixed side walls.
