Abstract
The utility model relates to a garden branch pruning device, in particular to a branch pruning device with an anti-pinch disk saw bit, which belongs to the technical field of garden machines. The branch pruning device can be arranged at the end of a stretchable arm of a project vehicle and driven by a hydraulic driving motor to reach a certain working speed , feeding of the cutting saw bit is driven by a hydraulic cylinder, and the branches of a tree or trees with smaller diameters can be cut. The branch pruning device improves an ordinary disk saw bit, and the disk saw bit is formed to be a regular elongated hole, so that the radial plate disk saw bit improves elasticity of the saw bit and deformations, two layers of saw bits in different diameters form a shape of a concave surface, certain gaps are retained after an assembly is carried out, so that the branch pruning device has sufficient deformations and elasticity. The branch pruning device is suitable for pruning and maintaining of the trees, cleaning of deadwood, management of a greenbelt of a super highway and cleaning of abrupt slope wood objects, particularly for cutting branches with larger diameters in a range from 150mm to 200mm.
Description
Technical field
The utility model relates to a kind of gardens branch pruning device, specifically is a kind of clamp-proof circular saw blade branch pruning device, belongs to the graden machine technical field.
Background technology
Along with socioeconomic fast development, people's living standard improves day by day at present, and the greening of environment is required to improve constantly, and the gardener safeguards that the task of the woods, flowers is very heavy.The pruning of common ornamental trees and shrubs is pruned with knife saw with safeguarding the employing manpower, and perhaps practical forestry lumbering is pruned with chain saw, and tiny branch adopts orchard shears to prune.Adopt manpower low with knife saw pruning trees efficient, some deadwoods drop and may meet accident and injure staff's health simultaneously, bring unsafe hidden danger; Chain saw is pruned and to be used more flexibly for bigger trees, but during for operation on certain height, the equipment of well not ascending a height operation is dangerous and inconvenient; Orchard shears has certain limitation, and is lower for thicker branch efficient, especially has the branch of certain altitude, and it is relatively large that the flexible stock of employing is cut labor strength, and operating efficiency is low.So far there is not good solution.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art part, a kind of clamp-proof circular saw blade branch pruning device is provided, this device is mounted in the telescopic arm end of engineering truck, power drive by hydraulic drive motor reaches certain working speed, and finish the feeding of cast-cutting saw slice, branch or the less a little trees of diameter of cutting trees by the driving of hydraulic jack.This device comprises common circular saw bit is improved, it is processed well-regulated strip hole, the connection of disc formula has improved the elasticity of saw blade, and increased deflection, adopt the saw blade of double-deck different-diameter to form concave, behind assembly, keep certain clearance, and have sufficient distortion and elasticity.Circular saw bit flexible and efficient succinct, developed the function that the plain disk saw blade does not have elasticity and anti-pinch, be applicable to the tree trimming maintenance of gardens and forest department, the cleaning of the residual tree of deadwood, the cleaning of management of expressway greening band and the wooden article in abrupt slope especially is fit to the bigger branch of 150～200mm and cuts off.
The utility model is realized with following technical scheme: a kind of clamp-proof circular saw blade branch pruning device, it includes: anchor clamps, hydraulic motor is arranged on the anchor clamps, be connected with high-pressure oil pipe and cutting machine power flexible axle on the hydraulic motor, also be fixed with bearing on the anchor clamps, it is characterized in that: be fixed with cast-cutting saw on the bearing and move oil cylinder, cast-cutting saw moves oil cylinder and is connected with revoliving arm, shaft coupling is arranged on the revoliving arm, shaft coupling connects cast-cutting saw slice by the umbrella shape speed increasing gear on its top, cast-cutting saw slice is the concave shape of double-deck different-diameter, be evenly distributed with the strip hole on the cast-cutting saw slice, the cast-cutting saw slice external diameter has sawtooth, also be connected with the support folder on the revoliving arm and drive oil cylinder, be fixed with on the anchor clamps and drive pincers and following clamp, wherein upward drive pincers and be connected with helping folder driving oil cylinder.
The utility model has the advantages that: this device improves design with common circular saw bit, it is processed well-regulated elongated hole, the connection of disc formula has improved the elasticity of saw blade, and increased deflection, adopt the saw blade of double-deck different-diameter to form concave, behind assembly, keep certain clearance, and have sufficient distortion and elasticity.Circular saw bit is flexible and efficient succinct, function with elasticity and anti-pinch, be applicable to the tree trimming maintenance of gardens and forest department, the cleaning of the residual tree of deadwood, the cleaning of management of expressway greening band and the wooden article in abrupt slope especially is fit to the bigger branch of 150～200mm and cuts off.
