The gear 62 is rotationally driven to rotate the fourth bevel gear (not shown), the fifth bevel gear (not shown), and the screw rod 42 in reverse to rotate the screw rod 42 in reverse. After the rotation, the lock block 40 is driven and slid into the lock hole 39, and after the tip end surface of the tail block 44 contacts the ceiling wall of the dovetail groove 47, the lock block 40 is moved. The slider 38 is locked again, and at this time, the guide rod 49 is farthest from the insertion groove 51, and the tip surface of the mounting block 54 is pressed by the second pressing spring 56 so that the tip surface of the mounting block 54 is the ceiling wall of the first sliding groove 55. And the second bevel gear 53 meshes with the third bevel gear 50 and the first bevel gear 61 again, that is, the device of the present invention returns to the initial state;

The plunging cylinder 21 in the device of the present invention is in a rotating state in the course of plunging and returning, whereby the inner wall of the dug pit plunged by the rotational frictional force is further flattened and plunged at the same time. Consolidation of the inner wall of the pit can be greatly increased, and the quality of the digging pit can be improved.

The quality of the earth pit can be improved, and at the same time, the device of the present invention has a function of organizing the surplus soil by distinguishing it from the conventional soil layer plunging equipment, and can significantly reduce the labor intensity and improve the construction efficiency.

The above is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited to this. Changes and substitutions that come up without the whole creative labor are covered by the protection scope of the present invention. Therefore, the scope of protection of the present invention is standardized on the scope of protection to which the right claim is limited.

The present invention takes up the field of construction construction technology, and specifically is a plunge equipment.

Soil layer plunging equipment is always used in the construction field, but conventional soil layer plunging equipment has a single installation mode and limited functions, so the excess soil generated after plunging is manually arranged. Must be done, which significantly increases labor intensity and reduces construction efficiency. In addition, since the conventional soil layer plunging equipment generally performs plunging operation with a drill head, the compaction of the soil pit after plunging is insufficient, and the collapse phenomenon is extremely likely to occur, and the soil after plunging is likely to occur. The mines are of poor quality and have safety issues that require improvement.
