Abstract

Pole shears special for kiwi branches comprise a shears body and a shearing force device. The shears body is composed of a single-edge blade holder and a double-edge blade holder. The shearing force device is composed of a support pole, pulleys and a shearing force pull rope. During use, the pole shears special for kiwi branches is raised, a sheared branch is clamped via blade edges of the shears body, then the bottom end of the support pole butts against the ground or other force application points, then a tail rope is pulled down forcibly, and then the movable blade holder can be driven to shear the branch. The pole shears have the advantages that since the support pole is mounted, kiwi tree branches in a high place can be sheared; the shears body is of the structure that the single-edge blade holder is penetratingly inserted between two edges of the dual-edge blade holder, blades cannot be shifted and misplaced, and incisions can be enabled to be flush; the blade edges are concave dual-arc edges, so that the branches cannot move outside during shearing; the dual-edge blade edges can enable the branches to be uniform in stress; by combination of various structures, the high branches of kiwi trees can be sheared quickly, and damage to internal tissue and cortical tissue is reduced.

Description

Kiwi fruit branches of tall trees dedicated scissors

Technical field

The utility model relates to a kind of planting tool, particularly a kind of kiwi fruit branches of tall trees dedicated scissors.

Background technology

In the cultivation management of kiwi fruit, plant training is the key technology that affects kiwi fruit output and quality, current known technology is generally to frame both sides, to extend to form 2 major branches, every 25-40 cm, cultivate 1 side shoot with major branch vertical direction, vertical with major branch direction, staggered to both sides along crossbeam, bearing basal shoot and fruit bearing shoot are by pumping on side shoot.When collateral generation surpasses crossbeam outermost end, when liftoff 50-60 cm, adopt cutting back to combine with sparse branching, the pruning that combines of long, medium and short branch.Pruning to water sprout, generally stays 5-6 bud cutting back, makes it sprout 2-3 branch.Long fruit bearing shoot to excessive growth, generally cuts on setting fruit position in last year and stays 3-4 bud.Long fruit branch and medium fruit branch are cut and stayed 2-3 bud.In whole production process, need a large amount of beta prunings.

Existing beta pruning instrument is due to its design defect, and when beta pruning, two blades are easily offset, so that is difficult to make the otch of branch concordant, even can make crust cracked, affects beta pruning effect.Once branch diameter is excessive a little, can outwards slide along the edge of a knife again, make shearing point away from hinge fulcrum, the scissors arm of force extends, moment strengthens, and causes and shears difficulty, even if cut off, also can make otch coarse, crust is cracked, destroys the interior tissue of branch cutting shoulder, impact healing.

In addition, also have a large amount of branches long aloft, only with people is high cannot beta pruning, taking helper can increase workload, and has certain danger.

Utility model content

Technical problem to be solved in the utility model is for the problems referred to above, provides a kind of edge of a knife that can make concordant, can avoid branch to move during shearing outward, also can shear the dedicated scissors of the kiwi fruit branch of eminence, to improve beta pruning quality and efficiency simultaneously.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is kiwi fruit branches of tall trees dedicated scissors, comprises scissor body and shear device, it is characterized in that described scissor body is configured to by single cutting tool horse and double-edged blade; Single cutting tool horse is with shearing bar, and knife-edge is the two curved edges of indent; Catling horse is with shearing bar, and knife-edge is the two curved edges of indent; Single cutting tool horse interts in the middle of the two-edged of catling horse and by the mutual hinge of fulcrum pivot pin, between the shearing bar of single cutting tool horse and the shearing bar of catling horse, has also installed tension spring; Described shear device consists of support bar, pulley and shearing stay cord; Wherein support bar is rectangular shaped frame structure, in frame top attaching fulcrum pivot pin being integrated with scissor body attaching; Pulley comprises single-blade bar pulley, twolip bar pulley, upper fulcrum pulley and lower fulcrum pulley, wherein single-blade bar pulley is arranged on the shearing bar tail end at single cutting tool horse place, twolip bar pulley is arranged on the shearing bar tail end at catling horse place, upper fulcrum pulley is arranged on the top of support bar, and lower fulcrum pulley is arranged on the position of distance support bar bottom, the below 150-180cm of support bar; Shearing stay cord fixedly ties up on single-blade bar pulley, is then overlapped on twolip bar pulley, then is overlapped on fulcrum pulley, then be overlapped on fulcrum pivot pin, is finally connected on lower fulcrum pulley around a circle the outer tail rope that stays.

During use, kiwi fruit branches of tall trees dedicated scissors is lifted, the knife-edge of scissor body is clamped by beta pruning bar, then the bottom of support bar is propped up on ground or other impetus, the more drop-down tail rope of exerting oneself, just can drive blade holder to shear branch.

The beneficial effects of the utility model are due to support bar being installed, and can shear the kiwi fruit branch of eminence; The structure that scissor body adopts single cutting tool horse to intert in the middle of the two-edged of catling horse, blade cannot be offset dislocation, can make otch concordant; Knife-edge is the two curved edges of indent, can make branch when shearing also not meeting move outward; Double-edged blade mouth can make branch stressed evenly; Various structures combination can make kiwi fruit eminence branch be sheared rapidly, and reduces interior tissue and cortical tissue's damage.
