Description
Technical field
The present invention relates to a kind of gardening pruning device, specifically refers to a kind of greening bridge wood and prunes structure.
Background technology
At present, distribution line going through streets and alleys common phenomenon of become, but distribution line and the tree line contradiction for existing between the trees of urban beautification are day by day deepened, particularly the trees on the downside of distribution line.Thus, tree trimming on the downside of distribution line becomes the key of city line safety work, if leaving its free growth, the own growth of trees is likely to touch circuit, cause circuit stress damaged or directly result in phase fault, so, can not only cause the most power supply in city to stop, be also possible to cause fire when serious.Additionally, the high-tension current carried in tree body can injure passing pedestrian, and the personal safety to overhauling the staff of circuit causes huge threat.Therefore, the trees on the downside of distribution line reasonably must be pruned.Traditional processing mode is, before laying-out, manually the branch on distribution line or trees to be pruned using apparatuses such as cutters, but such method operational hazards, and the personal safety of staff cannot be guaranteed；Another kind of modified by high-altitude operation vehicle, and this kind of mode is simple to operate, and safety coefficient is high, but the use cost of high-altitude operation vehicle is high, and suitable environment limitation is high.
The content of the invention
It is an object of the invention to provide a kind of greening bridge wood prunes structure, fast and easy is pruned to the trees on the downside of distribution line, and the use range of structure is pruned in increase, it is ensured that the branch for manually treating pruning on the ground carries out safety operation.
The purpose of the present invention is achieved through the following technical solutions：
A kind of greening bridge wood prunes structure, including screw rod and cutting base, sleeve is arranged with the screw rod, and the cutting base is run through in the screw rod upper end, two support blocks are installed in the cutting base upper surface, axis of rotation is arranged in two support blocks, and gear saw blade is fixed with the rotating shaft, the screw rod upper end is provided with bevel gear, and the angular wheel being engaged with bevel gear is provided with roller end；Also include the upper arm of the arc on the wall of cutting base side, the projection of arc is provided with the inside of the upper arm bending section, and width of the projection on the axis direction of the bending section is more than width of the upper arm on the axis direction.
During present invention work, sleeve and cutting base are manually lifted by needs, and the band saw cut adopted in prior art, the weight of itself is larger, needs to expend excessive muscle power when which is lifted, and increased working strength of the greening arbor when pruning, and the band saw cut for adopting is applied to large-scale branch, when cutting to middle-size and small-size branch, the length with saw is limited to, saw blade is easy to stuck in cut portion.And the present invention is in cutting, upper arm on the wall of cutting base side is applied to the residual part and cutting part of branch respectively with gear saw blade, so-called residual part refers to the part that branch is stayed on trunk after the completion of cutting, using suspension of the residual part to cutting base, so that operator can be capable of achieving the cutting action to branch under less force state, and the projection of arc is installed on the inside of the bending section of upper arm, the projection can be fitted with the outer circle wall of residual part, the width of projection is greater than the width of upper arm simultaneously, and then increase the contact area between upper arm and residual part, the cutting base in fixed point cutting is avoided non-directional swing occur, reduce the occurrence probability of security incident.The isolation material that sleeve can adopt intensity larger, so, can be avoided and injury of the high-tension current on trunk to workman and the impact to operating efficiency in operation.
Described rotation on cutting base is provided with minor arc plate, arc-shaped through-hole is provided with minor arc plate, backing pin and ratchet are additionally provided with cutting base, backing pin passes through arc-shaped through-hole, groove is provided with the inside of upper arm, minor arc plate is connected by torsion spring with groove, and the bottom of the upper arm is engaged with ratchet.When gear saw blade reaches branch to be cut, the trunk of branch is blocked by upper arm, minor arc plate can be freely rotated on cutting base, according to the size of branch diameter to be cut, upper arm directly can be adjusted the corner dimension of upper arm and vertical direction against branch, it is artificial to promote sleeve to cause gear saw blade to start to cut trunk, so that upper arm is subject to an active force towards gear saw blade, torsion spring stress causes upper arm bottom to separate with ratchet simultaneously, when during gear saw blade cuts, barrier or staff need rest for some reason, gear saw blade stops cutting trunk, torsion spring stress disappears and upper arm bottom is engaged again with ratchet, remain chucking power of the upper arm to trunk, pruning structure is avoided to fall and cause security incident.
The central angle of the arc-shaped through-hole is 15 ° ~ 60 °.The central angle size of arc-shaped through-hole, directly influence the slewing area of minor arc plate and upper arm, according to the diameter of trunk to be cut, when the central angle of arc-shaped through-hole is less than 15 °, the slewing area of upper arm is too small, gear saw blade can only cut the trunk of small diameter, cause the practicality of the present invention to reduce；When the central angle of arc-shaped through-hole is more than 60 °, the rotational angle of upper arm is excessive so that upper arm is clamped on trunk not closely, easily occurs in the situation of upper arm landing in cutting process.
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention utilizes suspension of the residual part to cutting base, so that operator can be capable of achieving the cutting action to branch under less force state, and the projection of arc is installed on the inside of the bending section of upper arm, the projection can be fitted with the outer circle wall of residual part, the width of projection is greater than the width of upper arm simultaneously, and then increase the contact area between upper arm and residual part, it is to avoid in fixed point cutting, there is non-directional swing in cutting base, reduces the occurrence probability of security incident.
2nd, the present invention when gear saw blade cut during for some reason barrier or staff need rest when, gear saw blade stops cutting trunk, torsion spring stress disappears and upper arm bottom is engaged again with ratchet, remain chucking power of the upper arm to trunk, it is to avoid prune structure and fall and cause security incident.
