Problems solved by technology

[0003] Most of the existing agricultural sprayers have spraying apertures, and the spraying pressure remains stable, so that the spraying range cannot be changed, which makes it unable to adapt to different regions and has relatively large limitations. When spraying different sizes of regions, it is necessary to replace different models. Sprayer, much less useful

Embodiment 1

[0059] see Figure 1-Figure 11 As shown, the purpose of this embodiment is to provide an agricultural sprayer that can change the spraying range based on pressure regulation, including a spray box body 10 and a spray chamber 20 installed on the side of the spray box body 10. The side box of the spray box body 10 is provided with a side box 110, the front end of the side box 110 is provided with a card slot 111, the inside of the card slot 111 is provided with a water pump 120, the rear end of the water pump 120 is connected with a water pipe 121, and the other end of the water pipe 121 is connected to the top of the spray box 10 and extends into the spray box 10 inner ends, the spray chamber 20 at least includes:

[0060] Nozzle 210, the inner end of the nozzle 210 is a hollow structure, the inside of the nozzle 210 is provided with an inner pipe 211, the side of one end of the nozzle 210 is connected with a nozzle 212, the nozzle 212 is a funnel-shaped structure, the side of ...

Embodiment 2

[0071] see Figure 12 As shown, in order to reduce the friction between it and the inner tube 211, the extruded part 2233 has a U-shaped structure, and the bottom end of the extruded part 2233 is provided with a rolling bar 2234, and a rolling part 2235 is sleeved on the rolling bar 2234, and the rolling part 2235 has a spherical structure. The rolling friction of the rolling element 2235 is small, which can reduce the abrasion of the extruding element 2233 and the outer side of the inner tube 211 and prolong the service life of the device.

Embodiment 3

[0073] see Figure 13 As shown, in order to avoid deviation, the rolling element 2235 is in a cylindrical structure, and the inner side of the rolling element 2235 is rotationally connected with the outer side of the rolling rod 2234 . The outer side of the inner tube 211 is squeezed by the rolling member 2235 to improve its stability and avoid deviation during the rolling process, resulting in that the squeezed area of ​​the inner tube 211 cannot achieve the effect of changing the pressure.

Abstract

The invention relates to an agricultural sprayer, in particular to an agricultural sprayer capable of changing the spraying range based on pressure regulation. The agricultural sprayer comprises a spraying box body and a spraying cavity installed on the side face of the spraying box body, the spraying cavity comprises a spraying pipe, an inner pipe is arranged on the inner side of the spraying pipe, a pair of extrusion mechanisms is arranged on the outer side of the spraying pipe, each extrusion mechanism comprises a pair of hydraulic rods, and one side of each hydraulic rod is connected with a connecting rod, a limiting groove is formed in the tail end of the side face of each connecting rod, and a clamping mechanism is arranged in each limiting groove. Through the arranged extrusion mechanisms, the hydraulic rods push the connecting rods to push a rotating shaft of the connecting rods, a rotating rod rotates towards the other side to drive an extrusion part to slide on the surface of the inner pipe, and due to the fact that the length of the extrusion part is not changed, when the extrusion part is perpendicular to the inner pipe, the extrusion part extrudes the two sides of the inner pipe, the inner space of the inner pipe is narrowed, and the pressure intensity is increased; therefore, the pressure intensity of the sprayed liquid in the inner pipe is increased, and the spraying range is enlarged accordingly.

Description

technical field [0001] The invention relates to an agricultural sprayer, in particular to an agricultural sprayer whose spraying range can be changed based on pressure regulation. Background technique [0002] Sprayer is a machine that disperses liquid into mist. It is a kind of machinery. It is divided into agricultural, medical and other uses (such as industrial use). Agricultural use is classified as agricultural machinery and plant protection machinery. It is widely used in general industrial equipment and medical equipment. , chemical equipment, agriculture (lawn and garden), tourist vehicles, special vehicles, ships, beverages, vehicle cleaning, carpet cleaning, ground cleaning, water purification and water treatment equipment. [0003] Most of the existing agricultural sprayers have spraying apertures, and the spraying pressure remains stable, so that the spraying range cannot be changed, which makes it unable to adapt to different regions and has relatively large lim...
