Shovel blade capable of removing attachments back and forth
The invention discloses a shovel blade capable of removing attachments back and forth and aims at realizing that the shovel blade capable of removing attachments back and forth is capable of improving the working efficiency, good in removal effect for different attachments and convenient to operate. The shovel blade comprises a blade, a shank and a shank sleeve; an upper blade is arranged on the upper surface of the blade; one end of the upper blade is bent to be provided with a hook-shaped cutting edge that is 30-50mm long and an included angle of 30 degrees is formed between the hook-shaped cutting edge and the upper blade; a lower blade is arranged on the lower surface of the blade; one end of the lower blade is bent to be provided with a hook-shaped cutting edge that is 15-35mm long and an included angle of 45 degrees is formed between the hook-shaped cutting edge and the lower blade; a blade groove of which the section is of a rectangular structure is formed in the shank in the axial direction at the position of the shank sleeve, and the tail portions of the upper blade, the blade and the lower blade are matched with the blade groove; when a hand pushes forwards, the blade is enabled to clear away attachments on a working surface; when the hand pulls back, the upper blade or the lower blade is enabled to clear away the attachments; as a result, the working efficiency is greatly improved.
