摘要：
The utility model refers to agricultural machinery, in particular to screw seeders for bulk materials, which can be used in sowing machines for selection production.The task solved by the declared utility model is to increase the uniformity of seeding.The technical result in the implementation of the claimed utility model is the elimination of the influence of the level of material in the hopper on the degree of filling of the interturn space of the screw.The screw sowing apparatus comprises a sowing apparatus body 1 including a receiving chamber 2 with an outlet port 3, a casing of the screw 4 in which a metering screw 5 is disposed. In the receiving chamber 2, a detachable hopper 6 is installed, with flat flaps 7, 8 installed in the lower base bunker with the possibility of rotation relative to the axes 9, 10, made on the longitudinal edges of the flaps.On the opposite ends of the axes of the shutters 7, 8 protruding beyond the removable hopper 6, spring-loaded levers 15, 16 are located at an angle to the flaps.On the front wall, in the direction of conveying the material by the metering screw, and the rear wall of the receiving chamber 2, the flaps 7, 8, offset relative to the longitudinal axis of the body and the vertical grooves mirrored with respect to each other, are displaced by the diameter of the axis of the flaps 7, 8.The position of the dampers in the open state above the dosing screw eliminates the influence of the seed level in the detachable hopper on the stability of the feeding by the dosing screw and improves the uniformity of sowing.Полезная модель относится к сельскохозяйственному машиностроению, в частности к шнековым высевающим аппаратам для сыпучих материалов, которые могут быть использованы в посевных машинах для селекционного производства.Задачей, решаемой заявленной полезной моделью, является повышение равномерности высева.Техническим результатом при осуществлении заявленной полезной модели является исключение влияния уровня материала в бун
