Abstract
The utility model discloses a special farmland spraying head, including attach fitting and sprinkler body, the attach fitting is linked with the sprinkler body spiral, the sprinkler body includes the shell and the body of exerting pressure, it is provided with the screw thread to correspond with the body of exerting pressure on the shell inner wall, the body of exerting pressure is linked with the shell inner wall through the screw thread soon, be provided with the through -hole on exerting pressure physically, the outside that the body and the shell of exerting pressure is connected is provided with spray head shell, spray head shell is the outer loudspeaker form setting of expanding, the last a plurality of orifice that is provided with of spray head shell. This special farmland spraying head simple structure sprays evenly, and it is big to spray the area, and application scope is wide, and liquid medicine, solution, nutrient solution or water all can use.
Description
Technical field
This utility model belongs to agricultural equipment technical field, is specifically related to a kind of farmland nozzle specially used.
Background technology
Crops of the prior art need to use shower nozzle that it is carried out spray water or pesticide, promote its growth and prevent pest and disease damage.Prior art the structure of shower nozzle include the head body of circle, head body shows to be provided with multiple spray orifice, by spraying liquid in spray orifice to Crops in Applying Fertilizer, parasite killing, water, head body spray area is less, the a certain position of crops can only be sprayed, easily cause hydrojet excessive or very few, wayward, and during actual hydrojet, need the field-crop such as full wafer Oryza glutinosa constituting flat surface, dish Seedling etc. carries out liquid sprinkling, if using head body of the prior art to spray, the somewhere in farmland can only be carried out a spray, the sprinkling efficiency is low, inconvenient operation.
Utility model content
The purpose of this utility model is to provide a kind of farmland nozzle specially used, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of farmland is nozzle specially used, including jointing and sprinkler body, described jointing links with sprinkler body spiral, described sprinkler body includes shell and pressure body, it is correspondingly arranged on screw thread with pressure body on described outer casing inner wall, described pressure body is linked with outer casing inner wall rotation by screw thread, it is provided with through hole on described pressure body, the outside that described pressure body and shell connect is provided with nozzle housing, described nozzle housing, in extending out horn-like setting, described nozzle housing is provided with several spray orifices.
Preferably, the through hole on described pressure body is at least provided with 5, and is provided with drainage screen in through hole.
Preferably, described sprinkler body is corresponding with nozzle housing is connected by thread seal.
Preferably, described injection diameter is 0.2mm-1mm.
Technique effect of the present utility model and advantage: this farmland is nozzle specially used, pressure body is set in shell, shell and nozzle housing are by the gap between threaded adjusting pressure body and nozzle housing, and regulate the areal extent of spray orifice ejection medicinal liquid on nozzle housing, and the through hole on pressure body can increase the flow of medicinal liquid, improve the spray drug effect rate of sprinkler body, the nozzle specially used simple in construction in this farmland, sprays uniformly, and spray area is big, applied widely, medicinal liquid, solution, nutritional solution or water all can use.
