Embodiment 1

[0054] This embodiment provides a spray head 3, and the spray head 3 is optionally arranged on a spray bar. The nozzle 3 provided in this embodiment can change the extension length of the nozzle 33, thereby changing the distance between the nozzle 33 and the spraying target, so that the medicine can be sprayed to the middle and lower part of the crop crown or the ground, and the spraying effect of the nozzle 3 is improved.

[0055] Specifically, refer to image 3 , the spray head 3 includes a housing 31 , a hose 32 and a nozzle 33 . The hose 32 has a first end and a second end. The first end of the hose 32 extends into the housing 31 and communicates with the liquid medicine tank. The second end of the hose 32 protrudes from the housing 31 and communicates with the The nozzle 33 enables the medicine to be delivered to the nozzle 33 through the hose 32, and the nozzle 33 sprays mist to complete the spraying operation.

[0056] Further, refer to Figure 4 The spray head 3 als...

Embodiment 2

[0071] refer to Figure 7 with 8 , the present embodiment provides a plant protection helicopter 10, the plant protection helicopter 10 optionally includes a fuselage 101, a main rotor 102 located above the fuselage 101, a landing gear 103 located below the fuselage 101, and a Tail pipe 104 on the rear side of the fuselage. The plant protection helicopter 10 is provided with a spraying device 20, which is used to spray crops. The spraying device 20 includes a spraying bar assembly 6 and a plurality of spraying heads 3 arranged on the spraying bar assembly 6 . The spray bar assembly 6 is optionally arranged on the landing gear 103 .

[0072] Specifically, the spray bar assembly 6 includes a first spray bar 61 and a second spray bar 62 . The first spray bar 61 is a linear structure extending along the first direction, and is symmetrical with respect to the central axis of the fuselage 101 (the central axis of the fuselage 101 is as follows: Figure 7 As shown by the dashed ...

Abstract

The invention discloses a spray head and a spray rod assembly, and belongs to the technical field of plant protection. The spray head comprises a shell, a hose, a rotating shaft and a first driving mechanism; one end of the hose extends into the shell, and the other end of the hose extends out of the shell and is connected with a nozzle; the rotating shaft is rotationally arranged in the shell; and the first driving mechanism is configured to drive the hose to be wound on the rotating shaft or released from the rotating shaft. The spray rod assembly comprises a first spraying rod and a secondspraying rod, and the first spraying rod and the second spraying rod are each provided with a plurality of the spray heads. According to the spray head, the extending length of the nozzle can be changed, and it is guaranteed that pesticide is sprayed to the lower middle portion of a crop plant crown or the ground.

Description

technical field [0001] The invention relates to the technical field of plant protection, in particular to a spray head and a spray bar assembly. Background technique [0002] my country is a large agricultural country with vast farmland and forests, so a lot of plant protection operations are required to spray crops with chemicals. The application of pesticides by plant protection helicopters has the advantages of high operating efficiency, good control effect, high utilization rate of pesticides, and large one-time operation area. Gradually replace labor and become the main force of plant protection operations. [0003] Such as figure 1 with 2 As shown, the nozzle 3' provided on the traditional spraying rod 2' cannot be adjusted, and the height of the plant protection helicopter 10' has a limit, so that the spray droplets can only be deposited on the upper part of the crop when spraying the medicine, and cannot reach the center of the crop crown. The lower part or the g...
