DEVICE FOR PRECISE FEEDING OF BULK MATERIALS Russian patent published in 2021 - IPC B65G65/40 F16K3/03 

FIELD: transportation.

SUBSTANCE: according to the invention, the device for precise feeding of bulk material for the extradition of bulk material with micro-adjustment of the quantity of bulk material, delivered in the downward direction from the outlet located at the bottom of the tank containing bulk material, and shipping bulk material to the device of the next stage contains multiple flaps located at the perimeter of the outlet, and the flap drive mechanism, which includes a driving force device, a transmission element and pulleys. The pulleys are connected to the driving force device by means of a transmission element. Multiple flaps are attached to the axes of the pulleys at one end, and the other ends rotate reciprocally under the influence of the driving force device, so that the flaps move in the gap between the outer periphery of the outlet and its center. The multiple flaps interact with each other to regulate the degree of opening/closing, while delivering a measured amount of bulk material.

EFFECT: purpose of the invention is to solve the problems of a device for feeding bulk material, in which a gate-type flap is used, and to create a device for precise feeding of bulk material, which, by delivering bulk material to the device of the next stage, accurately and stably regulates the speed of delivering bulk material vertically downwards.
