Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, 2, 3, the present invention includes frame 100, the working plate of frame 100 is provided with anchor clamps 10, and anchor clamps 10 are used for mower being fixed and being located, and guide pipe 9 is installed in the working plate below, guide pipe 9 is perpendicular to working plate, the bottom of guide pipe 9 is provided with stop collar 6, and the frame of guide pipe 9 belows is provided with installation sleeve 15, and the top is penetrated bar 4 and is sleeved in the installation sleeve 15, push up the register pin 7 that the upper end of penetrating bar 4 is provided with positioning steel tube 8, stage clip 5 supports to be contained in to push up and penetrates between bar 4 and the installation sleeve 15.The top is penetrated bar 4 lower ends and is connected with armature 3, and the frame 100 of armature 3 belows is provided with cylinder 1, and electromagnet 2 connects the piston rod of cylinder 1, and electromagnet 2 cooperates with armature 3.Electromagnet 2 other frames 100 are provided with insurance cylinder 14, are connected with safety block 13 on the piston rod of insurance cylinder 14.
State shown in Fig. 1, Fig. 2 is the initial standby condition of test, the top is penetrated bar 4 and be in lifting position under the effect of stage clip 5 and stop collar 6, at this moment the steel pipe 8 with specific standard inserts in the guide pipe 9, be inserted in the top and penetrate on the register pin 7 of bar 4 upper ends, the piston rod of cylinder 1 will be pushed on the electromagnet 2 and push up the armature 3 of penetrating bar 4 lower ends and contact; To electromagnet 2 energisings, adhesive armature 3, cylinder 1 action with electromagnet 2 and connected armature 3, that bar 4 is penetrated on the top is drop-down, at this moment, stage clip 5 is in compressive state, and subsequently, the piston rod of insurance cylinder 14 stretches out, safety block 13 is pushed the top (shielding) of armature 3, and the steel pipe 8 of specific standard is relying on Action of Gravity Field to drop to the position of Fig. 2; Mower 11 is fixed in place by anchor clamps 10, such as Fig. 2.
During test, such as Fig. 3, start mower 11, make blade 12 rotations, start insurance cylinder 14, make the 14 piston rod indentations of insurance cylinder, drive the top (arming) that safety block 13 shifts out armature 3, make electromagnet 2 dead electricity, armature 3 loses the suction-combining force, and stage clip 5 discharges rapidly to be penetrated the top at bar 4 and eject rapidly together with the steel pipe 8 of specific standard, insert in the rotating blade of in running order mower, make the blade stall, cut off the mower power supply after 15 seconds, off-test.
