Description
Technical field
The invention belongs to agricultural mechanical equipment fields, are related to a kind of fog machine more particularly to a kind of change line-spacing exploration type pair
Target device for administration of drugs.
Background technique
China is large agricultural country, and planting industry is most important agricultural production sector.Staple food crop has rice, wheat
Deng industrial crops have cotton, peanut, rape, tobacco leaf etc..Planting Row Distance is different between various crops, and position occurs for pest and disease damage
Difference, and equipment for plant protection domestic at present is more for orchard research, it is less for short crop pesticide spraying machine research, between spray head
Away from that cannot be adjusted according to practical Planting Row Distance, to the crop of different spacings plantation, wherein it is same to be exposed to outer soil
Application causes pesticide greatly to waste and the pollution in soil；The crop more luxuriant for blade, due to blocking for canopy, medicine
Liquid is difficult to be deposited on the position that canopy occurs below pest and disease damage.
The Chinese patent of Patent No. 201720747306.2 discloses a kind of " multi-functional spray bar type spraying machine ", can lead to
Medicine frame elevating mechanism is crossed to realize that medicine frame height adjusts, adapts to the height change of crop growth, it can by Display Rack Shen Shou mechanism
Medicine frame is folded when not in use, saves parking space；But its nozzle equidistant interval is arranged on medicine frame, the expansion of medicine frame
Spraying when use, covering surface is very wide, and spray head spacing cannot be adjusted according to practical Planting Row Distance, and it is same to be exposed to outer soil
Sample application causes pesticide waste and land pollution.To improve this problem, we devise, and " a kind of exploration type becomes line-spacing to target
Isobaric device for administration of drugs " (patent No. 201710617877.9), which can probe into spray head in rice rice clump, and adjustable height
Degree, the variable angle of bracket and wing support is made by level-one rotating device, makes corresponding tune to meet the practical Planting Row Distance of rice
It is whole, it realizes and target is administered；But spray head spacing still cannot be adjusted according to practical Planting Row Distance, cause pesticide waste and
Land pollution.
Summary of the invention
It is an object of the invention to be applied to target to row in view of the above-mentioned problems, research and develop a kind of change line-spacing exploration type spraying device
Medicine economizes on resources, and reduces environmental pollution.The present invention adopts the following technical scheme:
A kind of change line-spacing exploration type is to target device for administration of drugs, comprising: lifting device, guide rail bracket become line-spacing device and pipeline dress
It sets；
The lifting device is rectangle mount structure, is fixed on pesticide applicator, provides support for entire device for administration of drugs, including
