Abstract
The utility model discloses a spray rod and nozzle structure of a knapsack sprayer, which comprises spray heads, the spray rod and a joint. The utility model is characterized in that the spray rod is provided with at least two straight spray heads which are not positioned at the same position, and each straight spray head is positioned at the same plane. Except that the front end of each spray head is inclined outward, the rest spray heads are vertical to the spray rod. The utility model has large one-time spray operation area, high spray efficiency and uniform spray, and the phenomena of repeat spray and leak spray are not easy occur.
Description
The utility model relates to a kind of agricultural plant protection apparatus, is a kind of knapsack sprayer spray boom and nozzle structure specifically.
A kind of knapsack sprayer was arranged in the past, and the structure of its spray boom and shower nozzle is that the tip at spray boom is equipped with the shower nozzles that curve 90 degree, and this shower nozzle can be a single head list spray orifice, also can be the many spray orifices of disjunctor.This kind spray structure is simple, and is easy to use, and fault is easily got rid of, but its weak point is that each spraying operation area is little, and efficient is low, sprays inhomogeneously, easily causes and resprays or leak spray.
It is big that the purpose of this utility model is intended to provide an a kind of spraying operation area, and high efficiency is difficult for respraying and leaking the knapsack sprayer spray boom and the nozzle structure of spray.
Task of the present utility model is finished like this, knapsack sprayer spray boom and nozzle structure, it includes shower nozzle, spray boom, joint, it is characterized in that: have two on the spray boom at least not at the straight shower nozzle of same position, each straight shower nozzle at grade, each straight shower nozzle is except that tip outward-dipping, and all the other and spray boom are perpendicular.
The utility model one-stop operation spray area is big, the spraying efficiency height, and spray cloth is even, and difficult generation is resprayed and is leaked the spray phenomenon.
Fig. 1 is the straight type spray boom of a utility model structural representation.
Fig. 2 is the utility model T type spray boom structural representation.
Among the figure: 1. joint 2. spray booms 3. straight shower nozzles.
Below in conjunction with accompanying drawing two embodiment of the present utility model are described in further detail.
Embodiment one: 1 as shown in Figure 1, joint 1 is connected on the handle, spray boom 2 is a straight-bar, tip can be crooked, straight shower nozzle 3 has two at least, and at grade, and of removing tip of straight shower nozzle 3 outwards has 10-20 degree inclination angle, all the other are all perpendicular with spray boom 2, and the distance between each straight shower nozzle 3 then is to decide according to the different line-spacing of different crops.
Embodiment two: as shown in Figure 2, spray boom 2 is the T type, joint 1 is connected with handle at the middle part of spray boom 2, straight shower nozzle 3 has two at least, straight shower nozzle 3 is outside one's consideration except that being installed in the T type spray boom outward-dipping 10-20 in two ends, all the other are all perpendicular with spray boom, each straight shower nozzle 3 all at grade, the distance between them is decided according to the different distance of different crops equally.
