Abstract

The utility model relates to a grit excavating loader, which belongs to the technical field of engineering machinery. A stand is provided with two rotary first chains 1 synchronously driving; matched chamfers (7) synchronously driving are evenly distributed on the rotary first chains 1 through cross beams (6); grit accumulation devices are arranged in front of the rotary low ends of the rotary first chains and are matched with the chamfers (7); grits are loosened and accumulated through two sets of synchronously driving helical blades (10) which are propelled in opposite directions; and funnels (21) are arranged below and in front of the rotary high ends of the rotary first chains. The chamfers (7) can be automatically filled with the grits in the up conversion at the rotary low ends, and the grits in the chamfers can automatically slide into the funnels (21) so as to be bagged when a load goes up to the rotary high ends and is in the down conversion. The grit excavating loader integrates excavating and loading, can be flexibly used, has high efficiency, low energy consumption and a simple structure, is easy to move and transport, is convenient for small-sized design and manufacturing and is especially suitable for relieving flood disasters and dredging nearby at emergency to build breakwaters against the flood.
