Abstract

The invention discloses a scraper knife device for an engineering machine. The scraper knife device comprises a device body, a driving oil cylinder is arranged on one side wall of the device body, a scraper knife is connected to the driving oil cylinder through a supporting rod, and the supporting rod is of a hollow structure; a roller is further arranged on the side wall of the lower side of thedevice body, an installing groove is formed in the side wall of one side of the scraper knife, and the supporting rod is inserted into the installing groove; an installing block is arranged on the side wall of one side of the supporting rod located in the installing groove, and the installing block is of a hollow structure; a reel is rotationally connected to the interior of the installing block,a plurality of through holes are formed in the side wall of the installing block, and a clamping block matched with each through hole is arranged in the corresponding through hole in an inserted mode.The scraper knife device is simple in structure and convenient to use, the scraper knife can be easily disassembled from the supporting rod so as to meet the cleaning or maintenance or replacement operation; meanwhile, scraper teeth of the scraper knife can move in a reciprocating mode, soil can be loosened conveniently, and the certain protective effect on the scraper knife is achieved.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a shovel device for construction machinery. Background technique [0002] Traditional excavating machinery and shovel transport machinery adopt the integral welding connection of the shovel and the support rod. In a specific environment, if the corresponding shovel is needed, other specific engineering vehicles need to be replaced for operation. At the same time, the shovel It is very inconvenient when the knife needs to be maintained or cleaned; in addition, when the blade is loosening the soil and other operations, it directly uses the extrusion force to loosen the soil, which will cause greater wear and tear on the blade, and the effect of loosening the soil is relatively low. Difference. [0003] For this reason, we propose a shovel device for construction machinery to solve the problems in the prior art that the shovel is difficult to disassemble from the sup...
