Utility model content
The utility model provides portable powerful averruncator, and the cleaning that has solved trees branch and bamboo wood is in the past easily limited, cannot accomplish the problem of thoroughly putting in order.
The utility model is that technical solution problem is achieved through the following technical solutions: portable powerful averruncator, comprise cutting out section and running part, described cutting out section comprises quiet cutter head and knife section, on quiet cutter head, be provided with the edge of a knife matching with knife section, described running part comprises worm screw, worm gear, energy storage bar, ratchet, pull bar, described knife section is arranged on worm screw, worm and wheel engagement, worm gear and the engagement of energy storage bar, energy storage bar and ratchet engagement, on described energy storage bar, be socketed with energy-stored spring, and energy storage bar is provided with lock pin, described ratchet is connected with pull bar.
The edge of a knife on quiet cutter head matches with knife section, forms clip, and this clip opens along with the motion of knife section or be closed; Running part is realized gathering and the release of energy, first, by swinging pull bar, the motion of pull bar drives ratchet to rotate, and kinetic energy is sent to energy storage bar, energy storage bar is setting in motion compressed energy-storage spring under the effect of ratchet, meanwhile, energy storage bar drives worm gear to rotate, and worm gear correspondingly drives worm movement, knife section motion on worm screw, opens clip; The continuous motion of pull bar, energy-stored spring is constantly compressed, until reach capacity, the engagement of now ratchet disengaging and energy storage bar, now energy storage pull bar and lock pin are in percussion state, swing again along with pull bar, lock pin is pulled the trigger, energy-stored spring release pressure, energy storage bar, under the effect of energy-stored spring, drives worm gear reverse rotation, worm gear drives worm screw to do axial return movement, closed clip, finally utilizes worm and gear principle to form huge shearing thrust at clip, reaches the object of cutting off branch, bamboo pole etc.; When energy storage bar resets, ratchet also meshes with energy storage bar again.
Further, the outside of described energy-stored spring is provided with sleeve, and the length of described sleeve is equal to or greater than the length of energy storage bar.Sleeve can be fixed the motion bodily form of energy-stored spring, the working environment of energy-stored spring is played a protective role simultaneously.
Further, described quiet cutter head is provided with cavity, and knife section and worm screw are positioned at this cavity.Knife section and worm screw can move back and forth in this cavity, realize opening and closure of clip, make total more reasonable.
Further, the edge of a knife on described quiet cutter head and the edge of a knife of knife section are all curved, and cave inward.When shearing, the edge of a knife on quiet cutter head and the edge of a knife of knife section are just in time embraced branch or bamboo pole, and shear effect is better like this.
Further, described pull bar is provided with return spring.There is return spring, while carrying out eminence operation, pull bar of every swing, spring can reset pull bar, can reduce like this requirement of aid, needn't all by aid, pull bar be resetted at every turn.
Further, on pull bar, the one end away from ratchet is provided with draw ring.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model is by design cutting out section and running part, running part is by the swing of pull bar, energy-stored spring is compressed to the limit and then discharges, energy storage bar, under the effect of energy-stored spring, drives worm gear reverse rotation, worm gear drives worm screw to do axial return movement, closed clip, utilizes worm and gear principle to form huge shearing thrust at clip, and branch, bamboo pole etc. is easily cut off, can shear branch of far-end, eminence etc., thereby accomplish thorough cleaning.
(2) the utility model is easy to operate, is easy to realize, and labour intensity and the reduction work that can alleviate staff's operation maintenance are dangerous, simultaneously lightweight, are also easy to carry.
