Abstract

The present invention relates to a small multifunctional development machine for mining coal and repairing roadway. It includes self-propelled crawler body on which a hoeing machine and a cutting arm connecting device are mounted, said cutting arm connecting device is hinged with cutting arm, hinged swinging device and cutting head device whose cutting head can be leftwards and rightwards moved. Said cutting head device is hinge-connected with cutting arm by means of hinged swinging device, and can be removably connected. Said development machine can be matched with breaking hammer and percussion drill, so that it has several different functions.

Description

1. Technical field: [0001] The invention relates to a small-sized multifunctional roadheader used for excavation and roadway repairing in coal mines and other mines. 2. Background technology: [0002] The cutting arms of the existing small roadheader (100KW and below) cutting devices all adopt left and right swings, the whole cutting arm swings up and down, the cutting head is telescopic (some do not telescopic), and the body is lighter (below 25 tons). It can carry out tunneling operations in small roadways and is welcomed by coal mines. However, its function is single; and when encountering hard rock, the vibration is large, and the pick is seriously damaged, so it can only be used for tunneling in soft rock and coal seams, which limits the use of roadheaders. In addition, due to its single function, when other operations are required, it needs to be equipped with multiple operating machines, which increases equipment investment, affects the operation progress, increases ...
