SCREW FEEDER FOR BULK MATERIALS Russian patent published in 2021 - IPC B65B1/12 B65D88/68 

FIELD: food industry.

SUBSTANCE: invention relates to a device for dispensing bulk products and can be used in food, chemical and other industries. The auger dispenser for bulk materials contains a feed hopper 1, a feed nozzle 2, a hopper cover 3, on which a material level sensor 4 is installed, a vertical shaft 5 installed inside the hopper 1, along the axis of which a screw 6 is located in its lower part, enclosed in a screw pipe 7, which is attached to the lower edge of the feed hopper 1. The auger dispenser is equipped with a scraper 8 with an agitator 9 to prevent bridging. In the upper part of the hopper 1 above the auger 6, with the possibility of simultaneous rotation around a single axis, a flat horizontal blade 10 is mounted, horizontally leveling the surface of the bulk material loaded into the hopper to prevent errors in the readings of the material level sensor 4 installed on the cover of the hopper 3. One of the edges of the horizontal blade 10 is bent to the bottom of the hopper, thereby forming an acute angle α with the horizontal plane of the blade, the vertical shaft 5 together with the screw 6 rotates by means of the shaft drive 11, and the scraper drive 12 rotates the scraper 8 with the mixer 9 and the horizontal blade 10. The drive of the shaft 11 and the drive of the scraper 12 are mounted on the cover of the hopper 3.

EFFECT: invention improves the reliability of the operation of the device.
