The casing is then pulled out of the mud surface, and the plastic drain boards are combined with the anchor shoes and left in the soil together. The drain boards are cut manually with a sickle or scissors to complete a board insertion operation.

[0003] In the prior art, a Chinese utility model patent document with authorization announcement number CN202718082U discloses an automatic cutting mechanism for plastic drain boards of a plug-in machine, comprising a support frame, a fixed blade and a movable blade, wherein the fixed blade is horizontally fixed to the bottom of the support frame and is located on one side of the plastic drain board, and the movable blade is horizontally connected to the hydraulic cylinder and is located on the other side of the plastic drain board, and the hydraulic cylinder is installed at the bottom of the support frame, wherein the hydraulic cylinder drives the movable blade to cooperate with the fixed blade to cut the plastic drain board, but it occupies more internal space of the plug-in machine frame, which brings instability to the installation of the anchor shoe at the end of the plastic drainage belt after cutting.

[0004] Therefore, it is necessary to design an automatic shearing mechanism for the drainage board that can reduce the space occupied inside the board inserting machine frame and reduce the impact on the installation of the anchor shoe to solve the current technical problems.
