Description
Technical field
The present invention relates to afforestation, pruning device field, specifically, are that one kind has pruning serrated knife
Hand-push apparatus.
Background technology
Afforestation even more embodies gardens in a kind of mode for being not only used for now increasing green coverage, purify air
The engineering of design, garden, cell, or even city image, now current greening are widely used in urban construction, roadside greening and high speed
The isolation strip greening of highway.With the continuous expansion of the species and area that afforests now, for the work that gardens are repaired and safeguarded
Amount is also increasing, and in order to reach high efficiency, high-quality garden maintenance purpose, present pruning maintenance service is from the initial stage
Hand-operated tools prune be transitioned into electric tool, the semi-automatic pruning of internal combustion engine instrument.
What existing garden maintenance workload was maximum with pruning difficulty is the pruning in shrub gardens, due to the shrub speed of growth
Hurry up, prune cycle is short, and the branch and trunk with certain shearing strength, so, the quality of pruning tool is directly influenced repaiies
The quality that cuts and work efficiency.
The instrument of existing topiaries using serrated knife by two panels steel sawtooth piece overlap constitute, and by drive
Dynamic device drive wherein a piece of is moved along a straight line back and forth, formed with quiet tooth in the reciprocatory movement of dynamic tooth repeatedly staggeredly
Shear action, cuts off the purpose for reaching shearing so as to will be located at dynamic shrub between tooth and quiet tooth or flowers and plants.
There is following technical problem in shearing in existing serrated knife：1st, the acting surface that existing sawtooth blade is mutually sheared
In arranged in parallel, blade be not provided with, shear action is realized by the extruding force that drive mechanism is provided, accordingly, there exist shearing
Power is inadequate, it is impossible to realize the shearing of thicker branch；2nd, due to blade Integral design, when indivedual cutters tooth, card occur blunt, can only be by
Whole blade is changed, and improves cost；3rd, due to not designing single blade, in prolonged shrub shear history,
Easily appearance increases the gap between blade because cutting to cut hard object, so as to when softer nursery stock or leaveves are sheared, easily go out
Now cut and continuous situation.
Content of the invention
It is an object of the invention to provide a kind of hand-push apparatus with pruning serrated knife, for solving existing saw
Serrated knife is present in use：1st, shear ability is low, it is impossible to realize the rapid shearing compared with bough, and the scope of application is narrower；
2nd, the modular repair of serrated knife can not be carried out, increases tool maintenance cost；3rd, the gap between blade easily increases and is difficult to cut
Disconnected nursery stock plant.
The present invention is achieved through the following technical solutions：
A kind of topiaries go-cart that prunes for roadside greening, including railway carriage, installed in the handle of railway carriage afterbody, installed in car
