Push rod is upper and lower, front and back symmetrical structure, push rod right-hand member is fork configuration, fork configuration there is the through hole for installing roller, left end is arrow-shaped structure, its inclination angle of inclined plane is 45 °, arrow-shaped structure is left is the class cross coordinated with pick plate depending on shape, arrow is the fork-shaped of front and back structure, this fork configuration width is slightly larger than the external diameter of teeth groove extension spring, push rod is coordinated with pick plate by class cross, its installation direction along arrow left, each installation push rod stage clip before and after push rod, the left end of push rod stage clip is fixed on sealing plate, sealing plate is arranged in the rectangular channel of pick plate left side,
The rectangular channel of pick plate left side has the pin-and-hole with the center line symmetry moved towards up and down, pin-and-hole communicates with the circular hole of the up/down perforation on pick plate is vertical, the face of cylinder is milled with keyway to pick groove, and spacer pin is arranged in pin-and-hole, and spacer pin right-hand member is positioned in the keyway of pick groove.
The invention has the beneficial effects as follows:
The upper-lower position of pick can be changed by the right position controlling push rod, in the gatherer process pushing up coal and ground coal, realize the change for coal seam thickness and change the function of the mining height of pick, avoid coal to be bonded at coal top and bring difficulty to passing support, simultaneously by sealing plate, coordinating of pick groove and pick plate and coordinating of push rod and pick plate, the assemblies such as push rod stage clip, teeth groove extension spring and external environment are separated, under severe working environment, ensure cutting bit assembly not by the impact of dust, ickings.
