Description
Technical field
The present invention relates to walking weeders.
Background technique
Herbicide has certain side effect, can generate many harm in use, and in general, herbicide is to plant
Object, pathogen, edaphon and environment etc. all have a certain impact.And it will cause environmental pollution incessantly, and it also can be indirect
It causes harm to the human body.
Land pollution: after the herbicide spraying of farmland, it can not dissociated by the herbicidal composition that weeds absorb and be present in soil
In.Currently, it is long residual type that the chemical herbicide used, which has majority, their residual lives in the soil generally up to 36 months with
On.According to investigation, there is 20%~70% can remain in soil for a long time in the herbicide generally used in production at present, to make
Soil, underground water, grain are contaminated.
Be unfavorable for production estimation: crops can absorb and put aside herbicide, and biological tissue can be by a degree of
It destroys, its certain nutrient that should have can not be synthesized, so as to cause certain nutritional ingredients missing in crop and fruit.Weeding
Agent has certain inhibiting effect to crops such as wheat, corn and soybean, cottons in normal usage, if using not conforming to
Reason, influences crops normal development and maturation, leads to the recessive underproduction.Hunan Province's development test shows that herbicide side effect can be led
Cause rice, wheat, soybean, the corn underproduction 10.5%~26.8%.Any herbicide has certain residual life in the soil, has
Even up to 3~5 years, when herbicide residue amount is big, when rear stubble plantation sensitive crop, is also easy to produce phytotoxicity, and plant can not be normal
Growth, it is serious to cause to have no harvest.For example capsicum Newborn Leaves cannot normally be unfolded, young bird contracting elongation, leaf margin distortion, fruit is seriously abnormal
Shape is similar to " multiparity ", no commodity value.
Soil property decline, soil " cancerization " is exactly " cancer field " described in people, can not change stubble, target crop low output or root
This does not have harvest.In the Northeast in China, have there is large area because herbicide is excessively used for a long time in the ground such as Heilungkiang, Jilin
" cancer field ".
And it will cause environmental pollution incessantly, can also cause harm to the human body indirectly, have studies have shown that containing TCDD's
Phenoxy herbicides can increase human muscle, nerve and adipose tissue sarcoma and occur.It is exposed to crowd's hair of phenoxy herbicides
The number of the raw above tumour is 5-6 times of unexposed crowd.
The feed of animal edible pollution of herbicide encroaches on its liver, kidney, digestive organs, causes loss of appetite, hematopoiesis function by
Damage, it is gradually thin, failure and die.According to from Guizhou Province, herbicide residue poisoning causes an animal husbandry Development Co., Ltd
42 heavy ewe miscarriages, 33 are suffered from sheep death.These phenomenons show in pastoral area than more prominent.The mankind are edible by herbicide residue
The food stained causes serious influence to health, can cause alopecia, leukaemia, tumour, renal necrosis, caput femoris necrosis, pregnant
Woman such as easily miscarries at a variety of diseases.
Therefore it is imperative to eliminate grass for field machinery.Weeder currently on the market, only sub-fraction can field remove
Grass, but large labor intensity, low efficiency, the grass of line-spacing is except not clean, and the grass of spacing in the rows cannot remove, so cannot be pushed away well always
Extensively.It is imperative that it improves and innovates.
Summary of the invention
For above situation, for the defect for overcoming the prior art, the purpose of the present invention is just to provide a kind of walking weeding
Machine can effectively solve the problems, such as the efficient weeding in field.
The technical solution that the present invention solves is:
A kind of walking weeder, the weeder including car body and setting on the car body, the weeder include
It is vertically arranged vertical supporting bar on the car body, vertical supporting bar lower part is provided with the horizontal working arm stretched out outwardly, working arm

Weeding knife, guide sleeve are fixed on the front end of working arm, and guide sleeve is provided centrally with vertical pilot hole up and down, and telescopic mast is sliding
It is dynamic to be mounted in pilot hole, slide construction of the telescopic mast above and below guide sleeve is constituted, the upper end of telescopic mast is coaxially connected with height
Adjusting screw rod is installed with stop nut on height adjusting screw rod, compression spring, weeding is provided between stop nut and guide sleeve
Disk shield is fixed on the lower end of telescopic mast, and motor is fixed on the side wall of telescopic mast lower part and the shaft of motor is set downwards
It sets, equipped with the extending shaft coaxially connected in the shaft of motor, the lower end of extending shaft is protruded into below weeding disk shield, is protruded into
One end on equipped with the weeding cutterhead that is fixedly connected, weeding knife have it is multiple, in the following table for extending downwardly shape weeding cutterhead being arranged in
Face.
The working arm includes the first working arm and the second working arm being respectively hinged on vertical supporting bar, the first work
It is provided with the elastic telescopicing rod for both adjusting angle between arm and the second working arm, the first working arm and the second working arm
Front end is provided with weeding mechanism；
The elastic telescopicing rod includes the first rotary sleeve being hinged on the first working arm by first bearing and by the
Second rotary sleeve of two bearing hinge connections on the second working arm is fixedly connected on the first rotary sleeve towards the second rotary sleeve direction
The buffering sleeve of stretching buffers in sleeve and is provided with buffer spring, is connected on the second rotary sleeve towards the first rotary sleeve direction
The first length adjusting screws stretched out, the first length adjusting screws have length adjustment far from one end spinning of the second rotary sleeve in succession
Screw-casing, length adjustment screw-casing are connected with the second length adjusting screws far from one end spinning of the first length adjusting screws, the
