Embodiment:
For guaranteeing cutting range, these works adopt the lifting platform mode.Utilize lifting platform as the element task platform, mechanical arm is realized the flexible motion of a plurality of degree of freedom on platform.Lifting platform adopts scissor-type, and adjustable height is than higher.
The anti-side scheme of falling the tree-cohesion mechanism.For convenience Gardener author farthest simplifies the operation course, and these works have adopted symmetrical quadric chain and slider-crank mechanism (as shown in Figure 2) to fall the principle of tree-cohesion mechanism as anti-side.The shared bar of the crank 10 of slider-crank mechanism and the crank of four connecting rods organically combines two mechanisms.And the slide block lengthening is become an outer loop bar 13, on interior loop bar 12, slide.And outer loop bar and lifting platform link together by hold down gag 3.Inside and outside loop bar is locked by trip bolt.Earlier lifting platform is pushed away towards trunk during work, interior loop bar can withstand trunk earlier, continues to push away forward, and outer loop bar begins to slide on interior loop bar, until holding trunk tightly, last artificial lock-screw.
Workbench rotation scheme.Allow workbench rotation, be for workbench is pruned under the situation of lifting platform fixed-site, and in less space, have flexibility, increase the pruning scope.Lifting platform adopts square, turntable is that two long shaped plates are superimposed as cross form 25, adds a gripper shoe on decelerator 22, adds up-thrust bearing 23 between gripper shoe and turntable, dress four wheels 24 below turntable is realized the effect of supplemental support simultaneously.Same by the further driven rotary platform rotation of motor 21 drive decelerators.Its advantage is easy to process, rotate laborsaving, lower to the requirement of drive motors.
The mechanical arm stretching mechanism scheme.The present invention adopts three joint telescoping mechanisms to realize the flexible of mechanical arm.In second and third joint telescoping mechanism, the 3rd joint mechanism is positioned at the end of whole mechanical arm, and electric saw will be installed in this joint mechanism, consider that this joint mechanism can not be too big, to reduce the vibration when working simultaneously from electric saw as far as possible, avoid vibration to pass to pruner integral body,, utilize its force of rolling friction to realize the Telescopic of mechanical arm so adopt a pair of rubber wheel 33 to realize relatively moving of two, three joint mechanisms along mechanical arm.Yet the interior cover of telescopic arm is a metal side tube, directly is in contact with it with rubber wheel to occur the situation of skidding easily, so add rubber strip on interior cover metal side tube, has promptly increased the force of rolling friction of friction pulley.This cover mechanism has realized the self-locking of friction pulley with the motor direct-drive friction pulley that has worm type of reduction gearing when power is provided.(as shown in Figure 5) in first and second joint telescoping mechanism, consider that the gross weight of second and third grade telescopic arm and pruning mechanism is very big, so decision realizes between first and second two joints telescopic arm flexible with this kind of drive of leading screw 18 nuts.Be about to that nut will be packed in the telescopic arm of the second level and fixing with it, again with screw rod with after motor is connected, again motor is fixed on the first order telescopic arm 17.
The mechanical arm design that hoists.Use the crank 3 of a crank and rocker mechanism of decelerator drive of twin shaft output, mechanical arm is equivalent to rocking bar, by the design of minimum pressure angle, thrust is reduced.The steric configuration of crank and rocker mechanism can guarantee when pruning operation that again the branch that the key component of pruner is not fallen smashes simultaneously.
Pull branch and prune mechanism's design.By investigation and experiment to the tree trimming method in the afforestation, ensure operating personnel's safety again if find the damage minimum that trees are subjected to, need guarantee when the side shoot of trees is pruned, the position of its relative clipping device and clip to be fixed.For these these works have two little hands of machinery in the both sides of electric saw, when electric saw is near branch, can help electric saw that the fixed-site of branch is lived, pull branch and prune.
Design to manipulator is as follows: adopt the skeleton 27 of the slider-crank mechanism of symmetry as the little hand of machinery.The Slipper 28 of its folding of control is linked to each other with the saw cover of electric saw 30 by stage clip 29.When electric saw to rising and during near branch, the spring that saw puts promotes slide block and makes its closure, and branch is pulled.This moment electric saw continue to branch near and start, spring is compressed, the strength of mechanical little hand folder branch is increasing, and is sawed-off by electric saw until branch.This design has realized mechanical linkage, and the gardener's that is more convenient for operation also more meets pruning and must ask and process.
The Aerial Work LT mode that the present invention adopts helps guaranteeing cutting range, and cost is low, working stability.Generally speaking, these works mechanism is simple, is easy to processing, and key is to have overcome a series of difficult problems, and can realize Long-distance Control aspect electrical control, has taken into full account the stability of complete machine and operating personnel's personal safety and is embodied.
