This is a system that forms a column-shaped mixing pile while stirring, but especially on clayey ground, etc., the mixing and stirring function deteriorates due to clogging or retention of excavated soil during excavation. The present invention is a mechanism designed to solve this problem. Referring to the drawings, FIG. 1 is an overall view of the mechanism of the present invention, in which the tip end of the rotary shaft (2) of the punching machine (1) has a tip. As shown in the detailed view (FIG. 2), the cutting blade stages (3) and (4) and the coupling transmission type drive side pulley (5) of the embodiment of the present invention are welded and rotate integrally with the shaft (2). The stirring blade (6) is installed in the joint pulley (7) as shown in (Fig. 3), and the rotary shaft (2) is rotated forward (8) = the direction in which the cutting is advanced. At the time of rotation and reverse rotation (9), the stirring frame (6) is spread by the force of the spring (10) and stopped by friction with the wall of the hole, whereby the shaft (2) idles. The joint pulley (7) is constantly pushed up by the spring (11). FIG. 4 is a detailed view of the tip of the shaft (2) in the gear conduction type embodiment of the present invention. The cutting blade stages (3) and (4) in the figure and the gear (13) in the conduction block (12) shown in FIG. 5 are welded to the rotary shaft (2). As shown in the detailed view of the inside of the transmission block (Fig. 6), the gear (13) is fitted with the gear (14), but the shaft (2) is rotated forward (8) = the direction in which cutting is advanced = At this time, the gear (14) is set so as to move along with the gear (13) and stop at the position where the arrow pin (15) is engaged between the teeth. Therefore, if the forward rotation (8) continues further, the conduction block (12) itself follows the forward rotation. When the shaft (2) rotates in the reverse direction (9), the gear (14) becomes the gear (1
3) meshing with R, moving in the reverse direction, R-shaped wall (17)
It is set to idle around the position surrounded by. When the stirring block (16) is installed in the periphery of the conduction block (12) and the block rotates forward (8), it is rotated with a size equal to or smaller than the cutting hole diameter, and the shaft (2) rotates backward (9). , Spreads out and stops by friction with the wall of the hole, so that it idles with respect to the shaft (2). In both cases of the coupling type and the gear type, if the stirring blade is stopped by the reverse rotation, the clogging or stagnation of the cutting soil (18) between the cutting blade steps is eliminated by the continuous reverse rotation of the cutting blade. If the co-rotation caused by the clogging or stagnation of excavated soil is eliminated by the present invention, it is possible not only to save time and labor such as pulling out the entire axis to the ground each time as in the conventional case, but also to shorten the working time and to mix and mix. Is done precisely and can make a great contribution to the technology.
