[0002] During the agricultural planting process, agricultural products need to be sprayed with pesticides regularly to ensure the quality and yield of farm products. Due to the large agricultural planting area, most pesticides are sprayed by spraying, which is a method of spraying pesticide liquid into droplets suspended in the air using a sprayer, and then landing on crops or other treatment objects. It is one of the important methods of spraying pesticides to prevent and control agricultural and forestry pests, and can also be used to prevent and control sanitary pests and disinfect. At present, most traditional spraying machines are composed of a simple backpack, a shoulder strap and a spray system connected to a spray gun or a nozzle. When dispensing pesticides, it is usually necessary to add water to the proportion. At present, most of them are manually poured into the bottle mouth, and then water is added through the bottle mouth. This method of dosing is easy to cause pesticides to splash to the edge of the bottle mouth. At this time, if human hands touch it, it will cause certain human harm. In addition, due to the different spraying requirements of each farmland, the bottle mouth needs to be opened repeatedly to add medicine and water during each water replenishment process, which is cumbersome and inefficient.

DETAILED DESCRIPTION
[0018] The following is combined with Figure 1-3 This application is described in further detail.
[0019] The present application embodiment discloses a backpack pesticide spraying device. Figure 1 , including a spray back box 1, a back wall of the spray back box 1 is symmetrically fixed with shoulder straps 8, the shoulder straps 8 have a certain elasticity to enhance comfort, a connecting pipe 6 is fixedly installed on the bottom of one side of the spray back box 1, and a regulating valve 7 is installed on the connecting pipe 6, which can be connected to the spray system for spraying medicine, and sealed bottle caps 3 are sealed on both sides of the top of the spray back box 1. Water can be added to the interior of the spray back box 1 by opening the sealed bottle caps 3, and a scale window 2 is fixedly provided at the center of the outer wall of the spray back box 1, and the liquid solvent inside can be observed through the scale window 2.
[0020] like Figure 2-Figure 3 As shown, a dosing groove 4 is opened in the middle of the top of the spray back box 1, and a connecting pipe mouth 5 is fixed in the dosing groove 4. A sealing tube 9 is movably provided inside the connecting pipe mouth 5. A medicine storage bottle 10 is installed on the top of the sealing tube 9. The outer wall of the medicine storage bottle 10 is provided with a scale bar 11. The medicine storage bottle 10 is used to store pesticides. One end of the medicine storage bottle 10 is fixed with a connecting bottle head 12 in an integrated structure. An internal thread 13 is provided inside the sealing tube 9, and the internal thread 13 is adapted to the thread of the connecting bottle head 12, so that the medicine storage bottle 10 can be installed on the sealing tube 9.
[0021] Combination Figure 3 The bottom of the sealing tube 9 is an integrated structure with a sliding tube 15 fixed thereto, and a spring 14 is provided at the bottom end of the connecting pipe opening 5. The spring 14 is sleeved on the outside of the sliding tube 15, and one end of the sliding tube 15 away from the sealing tube 9 extends into the spray back box 1 and is fixed with a limited edge 16. Therefore, due to the elasticity of the spring 14, the sliding tube 15 can be pushed to drive the sealing tube 9 to slide in the connecting pipe opening 5.
[0022] In addition, a bracket 19 is fixed at the center of the top of the spray back box 1, and sliding grooves 17 adapted to the bracket 19 are provided on both sides of the bottom of the sliding tube 15 to facilitate sliding adaptation.
