PURPOSE: To remove soil adhering on a scoop body easily by installing a support piece falling by stepping at the central section of a pair of arcuate scoop bodies with shank levers and mounting a scraper brought into contact with the inner surface of the scoop body to the support piece.

CONSTITUTION: Arcuate scoop bodies 1 with shank levers are connected in a scissor shape while a scraper support piece 10 having a stepping piece 18 at a central section is energized by a coil spring 11 and set up. A scraper brought into contact with the inner surfaces of both-side scoop bodies 1, 2 is installed to the support piece 10. Soil adhering on the inner surfaces of the scoop bodies 1, 2 is removed by operating the scraper by stepping. Accordingly, the soil is dropped simply, thus improving the operating efficiency.
