Problems solved by technology

But 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 a variety of operating machines, which increases equipment investment, affects the progress of the operation, increases the operating cost, and is not easy to manage.

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 is a small multifunctional roadheader used for mining and tunneling and roadway repair in coal mines and other mines. 2. Background technology: [0002] The cutting arms of the cutting devices of the existing small roadheaders (100KW and below) adopt left and right swings, the cutting arms as a whole swing up and down, the cutting heads are telescopic (some are not), and the body is lighter (under 25 tons). Being able to carry out excavation operations in small tunnels is welcomed by coal mines. But its function is single; and when it encounters hard rock, the vibration is large, and the pick is severely 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 is necessary to equip multiple operation machinery, which increases equipment investment, affects the operation progress, increases operation costs, ...
