Horizontal axle bearing, the horizontal axle bearing are arranged in fixed block, and the fixed block is arranged on the horizontal shaft support plate, institute
State and a gear is also equipped with trunnion axis, a L-type motor, the L-type motor output shaft are installed on the horizontal shaft support plate
On be provided with the little gear engaged with the gear.
An optoelectronic switch is provided with the head shell, one is provided with the trunnion axis can block the light of optoelectronic switch
Electric switch baffle plate.
One material blocking block is installed on the head shell, it is corresponding with material blocking block spacing that one is provided with the trunnion axis
Block.
Trunnion axis oil sealing is installed on the lateral surface that the trunnion axis contacts with the head shell.
Sleeve is also set with the trunnion axis, the sleeve is between the gear, the fixed block.
The present invention has advantages below：The head luffing mechanism of the present invention, rotated by L-type motor driven trunnion axis, from
And upper backup pad pitching is driven, whole luffing structure is simple, and whole luffing structure is all to be detachably connected, so that should
The dismounting of head luffing mechanism is extremely convenient；By optoelectronic switch and optoelectronic switch baffle plate, so as to realize that the automatic of L-type motor stops
Only, and by limited block and fixed block, the luffing angle scope of luffing mechanism is further defined, and cause head pitching
Mechanism bows, faces upward conversion steadily.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
As shown in figure 1, a kind of head luffing mechanism, it include upper backup pad 1, support side plate 2, trunnion axis 12, outside head
Shell 16 and horizontal shaft support plate 8, the support side plate 2 are arranged on the both ends of the upper backup pad 1, the water by attachment screw
Flat axle 12 is arranged in the head shell 16, and the both ends of the trunnion axis 12 pass through the head shell 16, the level
The both ends of axle 12 are connected with the support side plate 2, and are locked by lock-screw 4, and the both ends of the trunnion axis 12 are set with
Horizontal axle bearing 14, the horizontal axle bearing 14 are arranged in fixed block 15, and the fixed block 15 is arranged on the trunnion axis branch
On fagging 8, a gear 6 is also equipped with the trunnion axis 12, a L-type motor 9, institute are installed on the horizontal shaft support plate 8
The little gear for being provided with the output shaft of L-type motor 9 and being engaged with the gear 6 is stated, the L-type motor 9 works, so as to moving gear
