Abstract

The invention relates to a coal mine iron shovel capable of adjusting coal shoveling mode, and belongs to the technical field of coal mine devices. The problems that the existing two types of shovelsare separated and thus inconvenient to carry and working intensity is increased can be solved. The coal mine iron shovel capable of adjusting coal shoveling mode comprises a handle, an iron shovel head, and the iron shovel head is mounted on one end of the handle; a plurality of second air passages are symmetrically arranged on a middle support lug, and the second air passages on the symmetric side of the middle support lug are all in communication with corresponding first air passages; two side support lugs are symmetrically mounted on the two sides of one end of a fixing shell; a round headplate is mounted on the fixing shell through cylindrical pins, each of the cylindrical pins penetrates through the two side support lugs and the middle support lug, and the cylindrical pins are fixedly connected with the two side support lugs. According to the coal mine iron shovel capable of adjusting coal shoveling mode, the iron shovel has the function of freely switching between a round head shovel and a square head shovel, using functions are more extensive than that of a traditional iron shovel, switching of the round head shovel and the square head shovel is convenient and quick, and the coal mine iron shovel capable of adjusting coal shoveling mode is structurally reasonable and obvious in terms of effect.

Description

technical field [0001] The invention belongs to the technical field of coal mine equipment, and in particular relates to an iron shovel with an adjustable coal shoveling mode used in coal mines. Background technique [0002] At present, the existing shovel has a simple structure and a single function. There is a kind of shovel with a flat rectangular semicircular pointed tip, which is suitable for stepping into the ground and turning the soil with your feet, so that the soil can be turned up easily. Another kind of shovel is a wide shovel A bucket or a slightly concave shovel body in the middle, equipped with a hand tool composed of a flat handle, digging or throwing materials (such as soil, coal, grain) by hand, the two types of shovels used in existing coal mines are separate, coal mines When workers need to use these two kinds of shovels, they need to carry two kinds of shovels. This will undoubtedly increase the work intensity of coal miners in the process of entering th...
