Title:
MIXER
Document Type and Number:
Japanese Patent JP2010071001
Kind Code:
A
Abstract:

To switch between continuous processing mode and batch processing mode as appropriate in accordance with the properties of the earth and sand which are to be improved.

The mixer is provided with a processing mode switching means 14 which consists of a first and a second rotary sensors 15, 16, a first and a second motors 19, 21, an input setting machine 23, a motor controller 24, or the like, and switching is performed as appropriate between the continuous processing mode and the batch processing mode. In the continuous processing mode, the right-and-left stirring shafts 6 and 10 are rotated in the same direction, and the improved soil is transferred from the earth-and-sand supply port 4 side of a mixing tank 3 to a discharge port 3F. In the batch processing mode, the right-and-left stirring shafts 6 and 10 are rotated in the direction opposite to each other, and the improved soil is transferred from the earth-and-sand supply port 4 side of the mixing tank 3 to the discharge port 3F by the left stirring shaft 6, and the improved soil is transferred from the discharge port 3F of the mixing tank 3 to the earth-and-sand supply port 4 side by the right stirring shaft 10. Because of this, the continuous processing mode and the batch processing mode can be selectively performed by using a single mixer 1, and the improved soil of good quality can always be generated regardless of the properties of the earth and sand.
