Description
Technical field
This utility model relates to agricultural machinery, particularly to the full power-driven circular cutting machine for fruit tree of one.
Background technology
The purpose of fruit tree girdling is to improve yield and the percentage of fertile fruit of fruit tree.Patent documentation CN102487737A discloses a kind of power-driven circular cutting machine for fruit tree, it is by fixed support on the body be provided with serrated knife, support is installed limiting plate, by regulate this limiting plate away from or near blade regulate cutting fruit tree the degree of depth, when regulating suitable, phloem can be cut off and not damage xylem, but this structure has an obvious defect, if the trunk out-of-flatness of fruit tree, such as grapefruit, there is a lot of depression, then due to the barrier effect of limiting plate, blade will cut less than or can not cut away completely the bark of recess.
In consideration of it, the present inventor develops a kind of full power-driven circular cutting machine for fruit tree for this, effectively solving the problems referred to above, this case thus produces.
Utility model content
A kind of full power-driven circular cutting machine for fruit tree that this utility model provides, it is adaptable to the smooth and irregular fruit tree of girdling trunk, and do not injure xylem.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of full power-driven circular cutting machine for fruit tree, including handle, driving means, spring, universal joint, sawtooth blade and blade mounting seat, sawtooth blade is arranged in blade mounting seat, sawtooth blade is connected by the power transmission shaft of universal joint and driving means, driving means is arranged in handle, installs the spring for balancing sawtooth blade stress between blade mounting seat and handle.
The cutter tooth of described sawtooth blade is the blunt knife tooth being difficult to cut xylem.
Described sawtooth blade includes the sharp cutter tooth arranged separately and is difficult to cut the blunt knife tooth of xylem, and the height of blunt knife tooth is slightly above the height of sharp cutter tooth.
Fixedly mount on described handle towards blade mounting seat fixing bar, blade mounting seat has the bar-shaped trough corresponding with fixing shank diameter, slides in one end of fixing bar is plugged on bar-shaped trough and along bar-shaped trough, and spring is located on this fixing bar.
There is on described fixing bar the graduation mark representing pressure.
Described blade mounting seat is directly decelerator, and sawtooth blade connects by the output shaft of blade shaft and decelerator is fixing, and the power shaft of universal joint and decelerator connects.
Described decelerator is turbine and worm decelerator.
Described driving means, for driving motor, drives motor to be driven by accumulator.
Described accumulator and handle are installed separately, the socket that handle has and drives motor to electrically connect, and accumulator has the plug of correspondence.
Control switch is installed on described handle.
After using such scheme, this utility model is unobstructed due to blade, therefore can the smooth and irregular fruit tree of girdling trunk.Simultaneously by the balanced action of spring, prevent the unexpected stress of sawtooth blade excessive and cut to xylem, detailed process is, the arm holding handle promotes too much to the direction of tree suddenly, sawtooth blade stress becomes big, spring will be compressed, sawtooth blade swings outside bark with universal joint, counteract arm distances promoted in bark more, user finds that blade swings out excessive, can know motive force excessive, user can reduce motive force, therefore has the effect preventing damaging trunk xylem.

Label declaration
Handle 1, fixing bar 11, graduation mark 111, control switch 12, spring 2, universal joint 3, sawtooth blade 4, blade shaft 41, blunt knife tooth 42, sharp cutter tooth 43, turbine and worm decelerator 5, output shaft 51, power shaft 52, bar-shaped trough 53, power transmission shaft 6, accumulator 7.
Detailed description of the invention
In order to the technical solution of the utility model is explained further, below by specific embodiment, the utility model is elaborated.
As Figure 1-4, it is a kind of full power-driven circular cutting machine for fruit tree that this utility model discloses, including handle 1, driving means (not shown in common structure figure), spring 2, universal joint 3, sawtooth blade 4 and blade mounting seat.
Wherein blade mounting seat is directly turbine and worm decelerator 5, and after sawtooth blade 4 connects by the output shaft 51 of blade shaft 41 and turbine and worm decelerator 5 is fixing, the power shaft 52 of turbine and worm decelerator 5 is connected by the power transmission shaft 6 of universal joint 3 and driving means.
Driving means, for driving motor, drives motor to be driven by accumulator 7, drives motor to be arranged in handle 1, handle 1 is provided with control switch 12, in order to control the start and stop of sawtooth blade 4 in real time.Accumulator 7 and handle 1 are for being installed separately, and the socket that handle 1 has and drives motor to electrically connect, accumulator 7 has the plug of correspondence.After accumulator 7 is installed separately, not only alleviate weight when holding, the volume of accumulator 7 can be increased simultaneously, improve flying power.
Fixedly mount on handle 1 towards turbine and worm decelerator 5 fixing bar 11, turbine and worm decelerator 5 has the bar-shaped trough 53 corresponding with fixing bar 11 diameter, and one end of fixing bar 11 is plugged in bar-shaped trough 53, and slides along bar-shaped trough 53.By fixing bar 11 and the cooperation of bar-shaped trough 53 so that sawtooth blade 4 can only be shaken the head swing.Spring 2 wears and is arranged on this fixing bar 11, is balanced the stress size of sawtooth blade 4 by this spring 2.
The fruit tree of different tree-walk sizes, its thickness is different, tree-walk is the biggest, bark is the thickest, during girdling, required power is the biggest, judges the size of required power for the convenience of the users, is carved with the graduation mark 111 representing pressure on fixing bar 11, when bar-shaped trough 53 did not had the graduation mark 111 of correspondence, i.e. represent that the radial force size that now sawtooth blade 4 is subject to is the numerical value on this graduation mark 111.
Spring 2 prevents the unexpected stress of sawtooth blade 4 excessive by its balanced action, the specific works process played a protective role is, the arm holding handle 1 promotes too much to the direction of tree suddenly, sawtooth blade 4 stress becomes big, spring 2 will be compressed, sawtooth blade 4 swings outside bark with universal joint 3, counteract arm distances promoted in bark more, user find that sawtooth blade 4 swings out when not have default graduation mark 111, can know the most excessive, thus reduce motive force to just the graduation mark 111 do not preset, therefore there is the effect preventing damaging trunk xylem.
So manual operation; firmly size is difficult to accurately control; for this, cutter tooth of sawtooth blade 4 is set to the blunt knife tooth 42 that is difficult to cut xylem; once blunt knife tooth 42 cuts to xylem; so its counteracting force being subject to will increase suddenly; sawtooth blade 4 will swing backward, make blunt knife tooth 42 be more difficult to cut xylem, play the effect of protection xylem.
In order to increase the cutting efficiency of sawtooth blade 4, arrange as it is shown in figure 5, sawtooth blade 4 is additionally provided with sharp cutter tooth 43, i.e. blunt knife tooth 42 and sharp cutter tooth 43 interval between two blunt knife teeth 42.The height of blunt knife tooth 42 is slightly above the height of sharp cutter tooth 43; should be slightly above; as long as blunt knife tooth 42 extends slightly out sharp cutter tooth 43; there is no concrete restriction; effect is, is increased the cutting speed of bark by sharp cutter tooth 43, takes the lead in contacting with xylem by the blunt knife tooth 42 of the sharpest cutter tooth 43 simultaneously; the very first time puts, to play a protective role after making sawtooth blade 4.
The present embodiment is unobstructed due to sawtooth blade 4, therefore can the bark of girdling arbitrary shape, and xylem will not be hurt, be particularly well-suited to the fruit tree that the barks such as girdling grapefruit are complex-shaped.
These are only preferred embodiment of the present utility model, the not restriction to protection domain of the present utility model.All equivalent variations done according to the mentality of designing of this case, each fall within the protection domain of this case.
