[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: Figure 1-Figure 6 As shown, the utility model provides a technical solution for an agricultural sprayer with a mixing structure, including a sprayer water tank 1, a water tank top cover 2, two handles 3, two shoulder straps 4 and an externally threaded tube 5, the bottom end of the externally threaded tube 5 is fixedly connected to a water inlet elbow 15, one end of the water inlet elbow 15 is arranged inside the sprayer water tank 1, a diverter box 9 is fixedly installed on the outside of the water inlet elbow 15, a plurality of diverter holes 10 are opened on the concave side of the diverter box 9, a plurality of small holes 8 are opened on the outside of the water inlet elbow 15, a guide piece 11 is fixedly connected to the top of the diverter box 9, and a measuring cup 12 is fixedly connected to the top of the guide piece 11.

[0026] First, the internal threaded member 6 on the outer side of the external threaded tube 5 fixedly connected to the top of the water tank top cover 2 is rotated to separate the internal threaded member 6 on the outer side of the external threaded tube 5 from the external threaded tube 5, and the rubber pad 7 fixedly connected to the bottom end of the internal threaded member 6 leaves the contact state with the water tank top cover 2, so that the top cover of the multiple air release grooves 16 arranged at the bottom of the rubber pad 7 and annularly distributed on the outer side of the external threaded tube 5 is removed. At this time, the multiple air release grooves 16 connect the inside of the sprayer water storage tank 1 with the outside, exhaust the inside of the sprayer water storage tank 1, and avoid the situation that the gas inside the sprayer water storage tank 1 is discharged when the sprayer water storage tank 1 is filled with water through the external threaded tube 5, resulting in the external threaded tube 5 not being able to enter the water smoothly; and the outer side of the measuring cup 12 arranged on the top of the water tank top cover 2 is threadedly sleeved with an internal threaded member 2 14, and the internal threaded member 2 14 is rotated and removed from the outer side of the measuring cup 12, so that a certain amount of pesticide can be poured into the measuring cup 12 during the process of filling the sprayer water storage tank 1 with water through the external threaded tube 5.

[0027] One end of the water inlet elbow 15 fixed at the bottom end of the external threaded tube 5 is arranged inside the sprayer water tank 1, so the water enters the sprayer water tank 1 under the guidance of the external threaded tube 5 and the water inlet elbow 15, and the water inlet elbow 15 is arranged in an L shape, and the position where the water falls into the sprayer water tank 1 is staggered from the top end of the external threaded tube 5, so as to avoid the water falling into the sprayer water tank 1 and contacting with the water mixed with pesticides to splash out of the sprayer water tank 1, and the pesticides splashing onto the user's body. In addition, a diversion box 9 is fixedly installed on the outside of the water inlet elbow 15, and a plurality of diversion holes 10 are opened on the concave side of the diversion box 9. The plurality of small holes 8 opened on the outside of the water inlet elbow 15 correspond to the plurality of diversion holes 10 one by one, so the inside of the water inlet elbow 15 is connected with the inside of the diversion box 9 through the plurality of small holes 8 and the plurality of diversion holes 10;

[0028] A guide member 11 is fixedly connected to the top of the diverter box 9, and the top of the guide member 11 is fixedly installed with a measuring cup 12. The drainage groove 13 opened in the measuring cup 12 is connected to the inside of the guide member 11, so the pesticide in the measuring cup 12 enters the inside of the guide member 11 through the drainage groove 13, and the pesticide enters the inside of the diverter box 9 under the guidance of the guide member 11. The multiple diverter holes 10 and the multiple small holes 8 are all inclined in the up and down direction or parallel to the horizontal plane, so that the pesticide in the diverter box 9 can completely enter the inside of the water inlet elbow 15 through the diverter holes 10 and the small holes 8. In the process of water entering the sprayer water storage tank 1 through the water inlet elbow 15, small amounts of pesticide continuously enter the water inlet elbow 15 from multiple positions through the multiple small holes 8 and mix with the flowing water. By setting structures such as the measuring cup 12, the guide member 11, and the diverter box 9, the time for the pesticide to enter the sprayer water storage tank 1 is prolonged, and the pesticide is dispersed and mixed with the flowing water inside the water inlet elbow 15, ensuring that the pesticide is evenly mixed with the water inside the sprayer water storage tank 1, thereby reducing the occurrence of a large difference in the pesticide content in the water inside the sprayer water storage tank 1.

[0029] A sliding frame 19 is inserted into one of the air release grooves 16. The sliding frame 19 is slidably connected to the water tank top cover 2 and can only move up and down. The bottom end of the sliding frame 19 is arranged inside the sprayer water tank 1 and fixedly connected with a floating block 20. When the water level inside the sprayer water tank 1 rises to a certain level, the sliding frame 19 floats up under the action of water, and the prompt plate 18 fixedly connected to the top of the sliding frame 19 rises. The prompt plate 18 with a brightly painted surface moves up to remind the user that the water level inside the sprayer water tank 1 has reached a certain height, and water can be stopped to avoid the situation where the water and pesticide mixture overflows due to excessive water addition inside the sprayer water tank 1.

[0030] A receiving groove 17 is provided on the top of the water tank top cover 2, and the receiving groove 17 is used to receive the prompt plate 18 so that the top surface of the prompt plate 18 is flush with the water tank top cover 2, ensuring that after the internal threaded part 6 is installed to the outside of the external threaded tube 5, the rubber pad 7 fixedly connected to the bottom of the internal threaded part 6 is deformed to block the sealing effect of the multiple air relief grooves 16.
