The invention relates to
coal mining equipment and specially, relates to a high-efficiency blocking
coal shovel. The high-efficiency blocking
coal shovel comprises a
shovel body. The shovel body comprises a frame. The high-efficiency blocking
coal shovel also comprises an impulsion shovel mechanism. The impulsion shovel mechanism comprises a shovel head and an impulsion device. The shovel head comprises shovel teeth and a fixing part. The shovel teeth are installed on the fixing part. A rear part of the fixing part is provided with an impulsion
stroke guiding mechanism. The impulsion
stroke guiding mechanism is sildingly connected to a guiding sleeve. The guiding sleeve is arranged on the impulsion device and / or the frame. The impulsion device impacts the impulsion
stroke guiding mechanism. Only through one impulsion process, the shovel head can complete both coal falling and
surface cleaning. The impulsion shovel mechanism is arranged on the shovel body. The shovel body drives the whole high-efficiency blocking
coal shovel to walk.
Coal mined by the high-efficiency blocking
coal shovel is not broken fully. The high-efficiency blocking coal shovel has a high blocking rate and low
power consumption, produces a small quantity of
coal dust, provides a good work environment, realizes continuous
coal mining, synchronously completes both coal falling and
surface cleaning, and saves a
mass of energy.
