Abstract

Described is an apparatus for closing and continuously emptying the container of a processing machine by means of a closure cover (6-9) which is arranged in the bottom (1) of the container and which is driven so that it can be moved into and out of the emptying opening (2) in the bottom (1) of the container by way of a pivotal shaft (17) acting as a lifting means on a mounting means, for example a mounting arm (16), outside the container. In order to permit both coarse and fine adjustment of the discharge rate in operation and also closure of the container, without incurring high levels of capital investment and also with robust operating characteristics, the invention provides that the closure cover (6-9) has a controllable rotary drive means (11, 14, 15), the pivotal shaft (17) acting as the lifting means is connected to a control drive means (21) for precise adjustment of the inclination of the mounting arm (16) and that the emptying opening (2) has a downwardly frustoconically flaring discharge hopper (4) into which the closure cover (6-9) can engage.
