specific Embodiment approach 1

[0013] Specific implementation mode one: combine figure 1 and image 3 Describe this embodiment, a portable sprinkler in this embodiment, including a high-pressure blower 1, an injector 2, a hose 3, a manual valve 4, a first mixing chamber 5, a first air intake pipe 6 and a back barrel 7, and The ejector 2 includes a receiving chamber 2-1, a mixing chamber 2-2 and a diffusion chamber 2-3, the receiving chamber 2-1 of the ejector 2 communicates with the air outlet 1-1 of the high-pressure fan 1, and the mixing chamber 2-2 The side wall is fixedly connected with the connection port 8 communicating with the mixing chamber 2-2, and one end of the hose 3 is communicated with the connection port 8, and the other end of the hose 3 is communicated with the first mixing chamber 5 through the manual valve 4, and the first The side wall of the mixing chamber 5 is provided with a plurality of first through holes 5-1, the top of the first mixing chamber 5 communicates with the gas outlet ...

specific Embodiment approach 2

[0027] Specific implementation mode two: combination figure 1 and Figure 4 Referring to this embodiment, the first air inlet pipe 6 is an F-shaped structure, including an air outlet end 6-1 at the bottom and two air inlet ends 6-2 at the upper part. In such a design, the two intake ports 6-2 both play the role of intake air, and at the same time, the pipeline where the lower intake port 6-2 is located also serves to support and fix the entire first intake pipe 6 and the first mixing chamber 5. Function, to avoid the position deformation of the first air intake pipe 6 and the first mixing chamber 5 due to the extrusion of solid particles or liquid in the back barrel 7, and even affect the intake air in the first mixing chamber 5. In addition, the first air intake pipe 6 It is also more convenient for processing. Other compositions and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0028] Specific implementation mode three: combination figure 1 and figure 2 Description of this embodiment, the mixing chamber 2-2 of the injector 2 is a cylindrical structure, the receiving chamber 2-1 and the diffusion chamber 2-3 are both conical structures, the small end of the receiving chamber 2-1 and the diffusion chamber 2 The small ends of -3 are respectively affixed to the two ends of the mixing chamber 2-2. Such design, wherein the diffusion chamber 2-3 is a hollow conical structure, the conical structure of the receiving chamber 2-1 can be determined according to the shape of the air outlet 1-1 of the high-pressure fan 1, if the air outlet 1-1 of the high-pressure fan 1 If it is a rectangle, the shape of the joint between the receiving chamber 2-1 and the air outlet 1-1 of the high-pressure fan 1 is a rectangle. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention relates to the technical field of agriculture, in particular to a portable spraying machine. The problems that existing pressing type spraying equipment and manual spraying are short in spraying range, small in spraying size and low in work efficiency are solved. The portable spraying machine comprises a high pressure fan, an ejector, a hose, a manual valve, a first mixing cavity, a first air inlet pipe and a back bucket. The ejector comprises a receiving chamber, a mixing chamber and a diffusion chamber. The receiving chamber of the ejector is communicated with an air outlet of the high pressure fan. The side wall of the mixing chamber is fixedly connected with a connector communicated with the mixing chamber. One end of the hose is communicated with the connector. The other end of the hose is communicated with the first mixing cavity through the manual valve. A plurality of through holes are formed in the side wall of the first mixing chamber. The top end of the first mixing cavity is communicated with the air outlet end of the first air inlet pipe. The air inlet end of the first air inlet pipe is arranged outside the back bucket. The portable spraying machine is used for spraying of agriculture and forestry.

Description

technical field [0001] The invention relates to a spraying machine, in particular to a portable spraying machine, which belongs to the field of agricultural technology. Background technique [0002] There are two methods of fertilizing pesticides and chemical fertilizers in the existing agricultural and forestry industry. One is manual spreading, which is low in efficiency, labor-intensive, and has a small fertilization area. Especially in rice fields, farmers have to go down to the field to fertilize because the fertilization area is small. The other is to use portable spraying equipment, which is mostly backpack-type and realizes the spraying function by pressing. The operator is easily tired after long-term operation. At the same time, most of the existing portable spraying equipment can only realize liquid spraying. It is impossible to effectively spray a large area, and the spraying device has a short range. Contents of the invention [0003] The present invention ai...
