Description
Technical field
The invention belongs to agricultural machinery technological field, weeding pine between a kind of mulberry field and the universal strain in orchard is especially related to
Native machine.
Background technique
In the plantation of xylophyta, weeds often with plant strain growth in plant around the end of ground, weeds
Nutrient can be fought for plant, propagate pest and disease damage and cause plant stem small and weak not only bad for plant strain growth, also will affect plant
Quality, it is therefore necessary in time remove plant between weeds.
Mode of commonly hoeing up weeds in production and living at present is manpower weeding or uses all kinds of herbicides, traditional people
There are working efficiencies for work mode lowly, labour expends the shortcomings such as big.Although herbicide can timely, thorough, quick, province
Power, conveniently, the removing weeds of saving of labor, but caused serious environmental pollution in recent years along with the use of a large amount of pesticides, it is miscellaneous
The drug resistance of grass also highlights.So invent weed and loose soil machine between a kind of mechanization, easy to operate, environmental-friendly strain has very much
It is necessary.
Summary of the invention
In view of the above deficiencies, it the present invention provides weed and loose soil machine between the universal strain in a kind of mulberry field and orchard, is able to solve
The problem of manpower weeding inefficiency, pollution of herbicide environment.

Support effect.
5 power input shaft of helical bevel gear reverser realizes the input of power, realizes speedup and power by chain 1
Transmitting.
The driven sprocket 8 drives weeding to loosen the soil 15 high speed rotation of shaft, realizes the high speed rotation of weeding Soil loosening tool,
And then realize that weeding is loosened the soil operation.
The tension spring 24 receives pulling force effect in the course of work, by elastic force produced by its drawing process to movable
Spiral arm 4 is resetted, reset final effect be anticollision wheel 18 not by stem resistance when movable spiral arm 4 state.
The present invention is connect with tractor by pin shaft by three-point type hanging frame 1, passes through the mobile drive complete machine of tractor
Movement, tractor PTO output imparts power to the power input shaft end of helical bevel gear reverser 5 by universal joint 14, real
The supply of existing complete machine operation power.
The present invention is mainly that xylophyta weeding is loosened the soil operation, applies and loosens the soil operation in the weeding of mulberry field and fruit.
The working principle of the invention and the course of work are as follows:
The present invention is suspended on tractor by three-point type hanging, the PTO and spiral of tractor are connected with universal joint 34
The power input shaft of bevel gear commutator 5, complete machine follow tractor mobile, provide power by tractor PTO, dilatory by adjusting
The outstanding support universal wheel 3 for making complete machine of machine bikini and ground face contact, make that universal wheel 3 is supported to play a supporting role.When selection weeding
Loosen the soil knife weeding system when, rotary head 21 is fixed on weeding and is loosened the soil 15 lower end of shaft；The weeding knife 19 that loosens the soil is solid by bolt
Due on rotary head 21, weeding is loosened the soil in 19 tip of knife insertion soil, and tractor is moved along plant side, makes the circle of anticollision wheel 18
The heart is overlapped with plant central line, and rotary head 21 is removed miscellaneous between strain and strain in high speed rotation under the drive of transmission system
Grass, when rotary head 21 is moved to plant root, anticollision wheel 18 is contacted with stem, and movable spiral arm 4 is inclined by resistance generation angle
Turn, while tension spring 24 is stretched and generates pulling force, anticollision wheel 18 along stem arc surface moving in rotation, at this time rotary head 21 with
Arc-shaped route is moved along stem surface, and weeding is loosened the soil under the passed by circular arc path of 15 high-speed rotation of shaft removing in moving process
The weeds of side, complete machine continues to move along, when being moved to 18 center of circle of anticollision wheel and tree diameters circle center line connecting perpendicular in plant
When heart straight line, 24 spring of tension spring reaches limit of stretch position, and movable spiral arm 4 is multiple under the pulling force effect of tension spring 24
, in reseting procedure, the route of rotary head 21 is still the circular arc along stem, and the weeds on route soil surface are by high speed rotation
Weeding is loosened the soil knife removing, and movable spiral arm 4 resets.When select mow rope weeding when, rotation cheese is mounted on weeding and is loosened the soil shaft
15 lower ends；Mow rope 36 rotation cheese 37 high speed drive under high speed rotation, mow rope 36 can by weeds crush bury, pass through
The type restricted is mowed in replacement can be for different weeds, the same first kind of other organisation operations.Strain is completed under the cooperation of each mechanism
The weeds uninterruptedly having no mechanical damage between strain are removed to be driven complete machine continuation to advance forward, enters with work of loosening the soil, tractor
Next weeding is loosened the soil the period.
In the present invention, according to remove different height weeds, optional weeding loosen the soil knife or mow rope weeding；Weeding pine
Native knife is mainly used in the shorter weeds of height and removes and buries, and has both the function of loosening the soil while removing weeds；Mowing rope weeding
It is that rope is cut in the relatively high weeds use of height to pump off crushing for higher-height weeds.
