[0002] Fruit trees are easily attacked by pests. In order to increase the growth life of fruit trees, fruit farmers have to spray pesticides on fruit trees to prevent pathogens from invading fruit trees. At present, spray guns are mainly used for spraying. When fruit farmers hold spray guns for spraying, part of the pesticides sprayed from the spray guns will flow back. The returned pesticides will adhere to the outer wall of the spray gun and even flow to the hands of fruit farmers, which will not only hurt the skin of fruit farmers' hands, but also make the pesticides remaining in the nozzle or even flowing to the outer wall of the spray gun. Under the influence of the external environment, it is easy to corrode the spray gun and volatilize, affecting the health and use of fruit farmers. Therefore, in view of the above problems, a fruit tree spraying device that can prevent the backflow of liquid medicine is proposed to solve the above problems. Summary of the invention

[0003] The purpose of the present invention is to provide a fruit tree spraying device capable of preventing the backflow of liquid medicine, so as to solve the problem proposed in the above background technology that when fruit farmers spray pesticides with a hand-held spray gun, part of the pesticide sprayed from the spray gun will flow back, and the returned pesticide will adhere to the outer wall of the spray gun and even flow onto the hands of the fruit farmers, which will not only hurt the skin of the fruit farmers' hands, but also make the pesticide remaining in the nozzle or even flowing to the outer wall of the spray gun, under the influence of the external environment, easily corrode the spray gun, and produce volatilization, affecting the health and use of the fruit farmers.

A micro water pump 13 is welded to the bottom end of the inside of the clean water tank 11, and a water pipe 15 is installed at the output end of the micro water pump 13. A pesticide adsorbent 18 is provided inside the sewage tank 12, and a collecting nozzle 14 is provided at the left side wall position of the sewage tank 12 below the nozzle 5.

[0018] According to the attached Figure 1 , attached Figure 2 and attached Figure 3As shown, the surfaces of the connecting rod 7 and the slider 9 are both provided with reserved holes, and bolts are installed inside the reserved holes through threads, a drain port 17 is provided at the bottom of the sewage tank 12, and a cover body is embedded inside the drain port 17 through threads, and the top of the cover body extends to the inside of the sewage tank 12 and is fixedly connected to the pesticide adsorbent 18, the collecting nozzle 14 is set to be funnel-shaped, and the bottom of the collecting nozzle 14 is connected to the left side wall of the sewage tank 12, the end of the water pipe 15 away from the micro water pump 13 passes through the top of the clean water tank 11, and the water pipe 15 extends to the top of the spray gun body 1, and the right side wall of the water pipe 15 is welded and fixed to the top of the box body 8, when the refluxed pesticide adheres to the surface of the nozzle 5, the fruit farmer's hand The gripping handle 6 is held to drive the box body 8 to move laterally along the slide groove 10 toward the nozzle 5. At the same time, the output end of the micro water pump 13 is in operation to discharge the clean water in the clean water tank 11 through the water conduit 15, and the nozzle 5 is fully sprayed and rinsed, so that the pesticide attached to the surface of the nozzle 5 is diluted by the clean water and falls into the collecting nozzle 14 with the clean water, and then is adsorbed by the pesticide adsorbent 18 and uniformly collected in the sewage tank 12, which can effectively prevent the nozzle 5 surface from flowing back and adhering to the outer wall of the spray gun body 1, and flowing along the spray gun body 1 to the hands of the fruit farmer, thereby solving the problem of the backflow pesticide causing harm to the fruit farmer's body and the problem of residual pesticide causing corrosion to the surface of the spray gun body 1.

The model of the micro water pump 13 is DC30A.

[0020] Working principle: Before spraying pesticides, the fruit farmer opens the water inlet 16 on the top of the clean water tank 11 and slowly pours clean water into the clean water tank 11. After pouring in an appropriate amount, the slider 9 slides horizontally in the slide groove 10, and the fruit farmer unscrews the bolt on the surface of the connecting rod 7 from the reserved hole. Then, the fruit farmer holds the upper handle of the spray gun body 1 with one hand and the hand-held grip 6 with the other hand, and drives the box body 8 to move horizontally along the slide groove 10 toward the nozzle 5 through the connecting rod 7 until the water pipe 15 moves to the top of the nozzle 5, stops moving, and inserts the bolt into the reserved hole again and tightens it.

[0021] Next, the pesticide spraying operation begins. After the pesticide passes through the external tube 2 and the spray gun body 1, it is sprayed out from the nozzle 5 at the left end of the spray gun body 1. At this time, the fruit farmer holds the upper handle of the spray gun body 1 with one hand and the hand-held grip 6 with the other hand, and sprays the fruit. At the same time, the pesticide sprayed back from the nozzle 5 on the spray gun body 1 will drip into the collecting nozzle 14. When the spraying work is completed, the fruit farmer starts the micro water pump 13 by pressing the operation button 3. The output end of the micro water pump 13 works and runs, and the clean water in the clean water tank 11 is discharged through the water pipe 15 and passes through the water pipe 1 The nozzle 5 is sprayed and flushed comprehensively, so that the pesticide attached to the surface of the nozzle 5 during the reflux falls into the collecting nozzle 14 together with the clean water after being flushed and diluted by the clean water, and then is adsorbed by the pesticide adsorbent 18 and uniformly collected in the sewage tank 12, wherein the pesticide adsorbent 18 is a solid substance that can effectively adsorb the pesticide components from the liquid. Finally, after the flushing is completed, the fruit farmer opens the cover body in the drain port 17 at the bottom of the sewage tank 12 to uniformly discharge the diluted and adsorbed pesticide sewage in the sewage tank 12. The above is the entire working principle of the present invention.
