Abstract
The invention relates to an auger feeder of concrete mix having a helical segment, which auger feeder has at least one insert (22), which is manufactured of material that is softer than that used for manufacturing the auger feeder's helical segment. One insert (22) is mounted on a downstream end of the auger feeder. The invention also relates to a method of manufacturing an auger feeder, which method includes manufacture of a helical segment of the auger feeder, in which method at least one insert is manufactured from a material softer than that used for the auger feeder's helical segment. The insert (22) is to be mounted on a downstream end of the auger feeder of the casting of the auger feeder's helical segment.
Claims9
An auger feeder for concrete mix, said auger feeder comprising:
- a cast helical segment,
- at least one annular insert mounted on a downstream end of the auger feeder, the annular insert having a gap cutting the annular shape in a cross direction, wherein the annular insert is manufactured of material that is softer than that used for manufacturing the cast helical segment, and wherein the annular insert is set into a cast mold of the auger feeder before casting the helical segment, and
- a cover plate covering at least part of an outer surface of a circumference of the annular insert at the area of the gap.
A method of manufacturing an auger feeder comprising;
- a setting at least one annular insert having a gap into a cast mold for the auger feeder before casting a helical art of the auger feeder, wherein the insert is mounted on a downstream end of the auger feeder
- casting a helical segment of the auger feeder in the cast mold, wherein the helical segment is cast from a material which is harder than the at least one insert.
