Description
Technical field
The utility model belongs to agricultural machinery technological field, fills more particularly to weeding between a kind of paddy field rice shoot strain in the ranks
It sets.
Background technique
China is populous large agricultural country, while being a grain big country, and Rice Production is raw in China's grain
Occupy very important status in production, there is 60% or more population in the whole nation using rice as staple food, China's Monitoring of Paddy Rice Plant Area about 0.3
Hundred million hectares, the 40% of Zhan Quanguo cereal cultivated area, the 28.2% of world's Monitoring of Paddy Rice Plant Area, however weeds in paddy field is striven with rice
Take the resources such as growing space, fertilizer nutrient, illumination, water, heat by force, influences the growth and development of rice, yield and quality of rice is caused to drop
Low, Rice Yield Loss Caused rate is 15% or more as caused by crop smothering every year, therefore, in the production process of rice, scientificlly and effectively
Control crop smothering is to ensure that one of rice healthy growth, high yield, good essential key link.
Chemical agent weeding is current most widely used weeding system, it have many advantages, such as it is quick, efficient, economical, so
And since the 1980s, in world wide, the large area of herbicide is used, and brings many negative issues, as weeds generate
Drug resistance, crop phytotoxicity, ecological environmental pollution etc., the reinforcement with the development of modern agriculture, people to environmental protection consciousness
With the attention to Food Quality Safety, so that herbicide decrement control technology has gradually developed, weeding by machine, agricultural are anti-
Except having obtained more researchs and application with the non-chemical weeding technique such as biological control, the non-chemical chemical weeding in Rice Cropping
Prevention Technique, mechanical weeding technology quickly grows, and has corresponding rice field weeding equipment to apply in agricultural production.
During paddy growth, being excessively used for herbicide not only reduces rice quality, but also contaminated soil and water source,
Ecological environment is destroyed, due to artificial weeding large labor intensity, weeding ratio is low, so weeding by machine is considered as " green rice " kind
Optimal weeding system during plant changes the way with chemical agent weeding using weeding by machine, and working efficiency is than artificial
Operation improves 5 times, and mechanical tillage and weeding is the loose soil of seedlings root growth and development, avoids and is caused using chemical herbicide
The shortcomings that soil cannot be effectively loose, and containment root system extends, promotes the growth of seedling, however, rice ploughs middle weeding machine at me
The development or blank of state, as what rice varieties and cultivation were studied gos deep into, to adapt to rice yield continuous improvement and mechanization
The needs of plantation, Japan, South Korea and China's most area use wide space planting, and the research for weeding technique between strain is domestic
It is still in infancy, the existing most of weeders in market can only remove inter-row weed, and be unable to reach reason for weeds between strain
The herbicidal effect thought, therefore, the weeder produced at this stage can only generally carry out individual event weeding operation, and the water of the utility model
Field weeder both can be carried out weeding in the ranks, while can also carry out weeding between strain, agriculture requirement is able to satisfy, to China's green agriculture
Development have great significance.
Summary of the invention

Weeding ratio, when weeder weeding in the ranks, weeds are pressed into mud by 2 rolls forward of weeding cage, are detached from mud in the gear teeth
When, the mud of gear teeth two sides closes up to centre buries weeds, so that weeds is not can be carried out photosynthesis, to reach weeding mesh in the ranks
, which is tested in field, has reached good effect；During weeder advances, one list of every advance
Position, spring wire drive rod a8 and spring wire drive rod b14 driving spring silk 20 are swung laterally once, and weeds between strain are played row
Between, 6 rolls forward of weeding cage 2 and monodentate weeding cage then in the ranks rolls weeds between strain in the soil of underwater, isolation
Oxygen achievees the purpose that weeding between strain；During weeder advances, seedling distributing device 9 in time separates rice seedling and weeds
Come, rice shoot is avoided to be damaged.
Between the seedling of paddy field weeder work when, rice seedling line space be 300mm, strain spacing be 12cm, 15cm or 18cm,
Device overall width is 2600mm, and effective weeding width is 2440mm, and weeding ratio is high, and will not damage rice seedling, can be to seedling
The root system portion soil progress of seedling is loose, improves the yield and quality of rice.
When weeder works between the seedling of paddy field, weeding cage 2 and spring wire 20, all work paddy field underwater soil layer it
In, when removing the weeds around rice shoot, soil layer is uniformly squeezed and is stirred, so that soil is overturn and is stirred, thus
It releives soil, increases the exchange of the nutriment between water layer and soil layer, promote absorption of the plant root to nutrition, improve water
Rice yield, meanwhile, weeding by machine can be reduced harm of the chemicals to environment and the phytotoxicity to rice shoot, improve the mouth of rice
Sense.
The above is only the preferred embodiment of the utility model only, is not intended to limit the protection model of the utility model
It encloses.Any modification, equivalent substitution, improvement and etc. made within the spirit and principle of the present invention, are all contained in this reality
With in novel protection scope.
