DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0024] Reference Figure 1 、 Figure 2 , a high-pressure spraying device, including a body 1, a control rod 2, a spray pipe 3, a high-pressure nozzle 4 and a strap 5, the control rod 2 is arranged on the side wall of the body 1, the spray pipe 3 is connected to the body 1 through a connecting pipe, the high-pressure nozzle 4 is fixedly installed at the end of the spray pipe 3, the strap 5 is arranged on the side wall of the body 1, and the strap 5 adopts a widened nylon breathable strap to increase the stability of carrying the body 1; a filter 6 is provided on the wall of the spray pipe 3, the filter 6 includes a first shell 7, a second shell 8 and a filter screen 9, the first shell 7 and the second shell 8 are threadedly connected, the inner side wall of the first shell 7 is fixedly provided with a support ring 10, the inner side wall of the second shell 8 is fixedly provided with a pressure ring 11, and the second shell 8 is fixedly provided with a plurality of L-shaped connecting rods 14 extending to the interior of the first shell 7 around the inner wall, and one end of the plurality of L-shaped connecting rods 14 is fixedly connected to the top of the pressure ring 11, and the filter screen 9 is located between the support ring 10 and the pressure ring 11. The support ring 10 and the pressure ring 11 can limit and press the filter screen 9 to the interior of the first shell 7. The filter screen 9 adopts a PP filter screen, and the aperture size of the filter screen 9 is 20-100 mesh. The PE material is soft and non-toxic. Its softness makes its flow resistance to the pesticide solution smaller during the filtration process, which is conducive to maintaining the normal pressure and flow of the sprayer. The aperture size setting is mainly used to intercept larger particles of impurities, such as leaf fragments, mud and sand, insect corpses, etc.

[0025] When the pesticide liquid enters the spray pipe 3, it will pass through the filter screen 9 inside the first shell 7 and the second shell 8, which can filter out impurities and undissolved pesticide particles, avoiding the situation where the pesticide liquid causes repeated blockage of the high-pressure nozzle 4, thereby improving the efficiency of pesticide spraying.

[0026] Reference Figure 2 、 Figure 3The opening edge of the first shell 7 is fixed with a threaded ring 12, and the opening edge of the second shell 8 is provided with a threaded groove 13 matched with the threaded ring 12. After the pesticide spraying is finished, the operator can rotate the first shell 7 by hand, so that the threaded ring 12 on the first shell 7 is moved out from the inner thread of the threaded groove 13. At this time, the first shell 7 is separated from the second shell 8, and the compression ring 11 is moved out from the inside of the first shell 7, so that the filter screen 9 can be taken off from the supporting ring 10. The impurities filtered by the filter screen 9 can be cleaned, and after the cleaning is finished, the filter screen 9 is installed between the first shell 7 and the second shell 8.

[0027] With reference to Figure 1 The position of the pipe wall of the pesticide spraying pipe 3 and close to the high-pressure nozzle 4 is fixed with a lifting tray 15. When the pesticide is filled into the inside of the machine body 1, the pesticide spraying pipe 3 is generally placed on the ground, and the high-pressure nozzle 4 can be in contact with the ground. At this time, the lifting tray 15 is in contact with the ground, so that the high-pressure nozzle 4 is placed at a certain height from the ground, and the phenomenon that the high-pressure nozzle 4 is polluted and blocked by the soil is avoided.

[0028] The above is only the preferred specific implementation mode of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
